The purpose of this study was to compare the efficacy and tolerability of PDT using short incubation time, broad area treatment with ALA plus activation with either blue light or laser light to topical 5-FU in the treatment of AK of the face and scalp.
Thirty-six subjects with AK of either the face or scalp were randomized to receive either application of ALA for 1 hour followed by activation with blue light or pulsed dye laser or topical 5-FU. Efficacy was evaluated by grading AK lesions and photoaging signs. Tolerability was assessed by scoring crusting /erosions, erythema and stinging /burning.
Treatment with PDT using ALA plus blue light was as effective as topical 5-FU in clearing AK. PDT using ALA plus laser light was the least effective treatment. All treatments made improvements in the signs of photoaging. Both PDT treatments were better tolerated than 5-FU.
In conclusion, broad area PDT treatment with ALA plus activation with blue light appears to be as effective as 5–FU in the treatment of AK. ALA plus laser light is somewhat less effective than the above therapies. Efficacy could likely be improved with further study of laser parameters and incubation tim

Objective Melanin Measurements: Review of Novel Dosimetry Guidance Device for Intense Pulsed Light in Aesthetic Treatments
E. Victor Ross MD,a Travis W. Blalock MD,a Douglas Winstanley DO,a Joel L. Cohen MD,b and James J. Childs PhDc| |
METHODS: A handheld meter was applied to non sun-damaged skin on the back of volunteers to measure skin pigmentation prior to treatment with IPL light sources over a range of pulse widths and ascending fluences. Curves for maximum epidermal tolerances as a function of pigmentation were determined. These curves were then tabulated for each pulse width in device software to provide guidance in the selection of fluences. Based on these findings, the device was applied in over 300 patients at a comprehensive laser and cosmetic dermatology center.
RESULTS: A pigment meter evaluation led to treatment parameter guidance in intense pulsed light applications. These suggested ranges for settings based on the melanin index score proved useful, accurate, and safe in applications over a broad range of skin colors and across various anatomic units of the skin.
CONCLUSION: A pigment meter can be used to identify appropriate settings with IPL treatments in order to enhance safety and efficacy when treating epidermal pigmented lesions, vessels, general photodamage and excessive hair (where the principles of selective photothermolysis are applied).

Photodynamic therapy (PDT) uses a topical photosensitizing agent which is activated by a light source to cause destruction of specific cells. Commonly used for the treatment of actinic keratoses and photodamage, PDT can also be used for other conditions including acne and sebaceous hyperplasia. Here we report our experience with two treatment protocols. The first protocol utilizes laser assisted delivery of topical 5-aminolevulinic acid for enhanced efficacy of blue light photodynamic therapy in the treatment of actinic keratoses and photodamage. The second protocol utilizes red light photodynamic therapy followed by pulsed dye laser to effectively target sebaceous glands in patients with extensive sebaceous hyperplasia.

A Retrospective Study on Efficacy of Pulsed Dye Laser and Intense Pulsed Light for the Treatment of Facial Telangiectasia
Lin Gao MD PhD,* Ni Gao MD,* Wenting Song MD, Erle Dang MD PhD, Rong Yin MD PhD, Li Wang MD, and Gang Wang MD PhD| |
Both pulsed dye laser (PDL) and intense pulsed light (IPL) systems have been demonstrated to be effective for treatment of facial telangiectasia, however there have been very few comparative studies between both treatments involving purely Asian patient populations. In this study, we performed a retrospective analysis to compare the efficacy of PDL and IPL systems for the treatment of facial telangiectasia. A total of 416 patients with facial telangiectasia who were treated by PDL or IPLs in our department from August 2012 to March 2015 were included in this study. The subjects received one of the following five treatments: PDL 595 nm (9-12 J/cm2), MaxG (500-670 nm & 870-1200 nm, 30-46 J/cm2), IPL (560-1200 nm, 18-24 J/cm2), M22 560 (560-1200 nm, 15-18 J/cm2), and M22 590 (590-1200 nm, 15-20 J/cm2). Each treatment had two sessions with 6-week intervals. The improvement percentage score in facial telangiectasia after the final treatment was evaluated by two non-treating physicians. We found almost all patients (less than 95.00%) had marked improvements or nearly complete clearance of the lesions after PDL 595 nm or MaxG treatment, as compared to 41.38%-56.58% patients in the other three groups that showed similar degrees of improvements. Both PDL 595 nm (9-12 J/cm2) and MaxG (500-670 nm & 870-1200 nm, 30-46 J/cm2) treatments resulted in significantly superior vessel clearance than the IPL systems with other wavelength bands (560-1200 nm or 590-1200 nm) and relatively lower fluence (15-24 J/cm2). Our results also suggested fluence levels account for the significant differences in the effectiveness delivered by different IPL systems. We concluded that PDL 595 nm and MaxG showed comparable clinical efficacy and both treatments resulted in most beneficial outcomes.

Recent U.S. population statistics reveal dramatically shifting demographics that would anticipate a likely increase in this percentage. U.S. Census Bureau data projects that by 2050, people of color are expected to become the majority, comprising 54% of the U.S. population, with Latinos accounting for 30%, African Americans 15%, and Asians 9.2%. The rising popularity of cutaneous laser surgery as an accepted therapy for various skin pathologies, coupled with the diverse face of the patient population, has led to increased demand for laser treatment of darker skin tones.
Although difficult, effective laser therapy in patients with darker skin phototypes can be achieved. When determining a treatment protocol for an individual patient, the proper laser energy and wavelength are important in ensuring a substantial margin of safety while still achieving satisfactory results.

OBJECTIVE: To review published clinical experiences (case series and case reports) using LLLT for treatment of DFU, and provide evidence-based recommendations and future directions on the potential of LLLT as a therapeutic modality for DFU.
METHODS AND MATERIALS: On January 16, 2016 we searched the published literature using databases: PubMed, EMBASE, CINAHL, and Web of Science with key terms: “diabetic foot” AND (“low level laser therapy” OR “low level light therapy” OR “LLLT” OR “light emitting diode” OR “phototherapy” OR “laser”).
RESULTS: After screening of titles, abstracts and/or full-text, 7 original articles were suitable in our review. Our review contains 5 case series and 2 case reports that evaluated LLLT for treatment of DFU, and all reviewed studies have shown positive improvement of DFU using LLLT with no adverse events, albeit with limitations that may be minimized with future RCTs.
CONCLUSIONS: LLLT is an emerging and promising treatment modality to current alternatives that are costly and have shown limited success. Based upon the published evidence, we envision additional research may allow for stronger recommendation with LLLT for treatment of DFU.

Prospective Efficacy and Safety Evaluation of Laser Treatments With Real-Time Temperature Feedback for Fungal Onychomycosis
Jill Waibel MD, Adam Jared Wulkan MD, and Ashley Rudnick| |
METHODS: Twenty-one patients with PAS or culture proven fungal onychomycosis were prospectively treated with laser until target temperature of 46 - 48 degrees Celsius was achieved using real-time infrared temperature feedback. The laser and light therapies used were 1319nm, 1064nm and BroadBand Light. Exclusion criteria included mixed infection and no other prior therapeutic interventions. Subjects received four treatment sessions one week apart. Assessments included PAS & cultures at one, three and six months post treatment. Patients also were asked a pain score from 1-10 during treatment.
RESULTS: Patients tolerated the procedures well with high satisfaction. Average treatment time was 10 minutes. No adverse events were noted. Patients reported mild-moderate transient discomfort during treatment. Six-month culture results revealed 20/21 negative for fungal organisms.
CONCLUSION: Laser therapy offers a safe and effective new option for onychomycosis. This may be the optimal therapy for a large market that needs alternative or adjunct to current therapies. Laser is quick, painless therapy that does not require any oral medications or blood test for monitoring. Additional larger scientific studies are needed to confirm our pilot study results.

Methods: A retrospective study of 313 consecutive laser-assisted hair removal treatments was conducted on a total of 23 patients (22 women, 1 man) with 58 anatomic areas by means of an alexandrite laser. Skin types of III and IV were represented. The long-pulsed alexandrite system (Aphrodite, Quanta system, Italy) was used at a 755-nm wavelength to deliver fluences ranging from 17 to 25 j/cm2 through a 10 mm spot size. The patients were divided into 4 groups according to the number of treatments (group I ? 4, group II = 5, group III = 6, and group IV ? 7 treatments). Digital photographs of the patients were used for hair counting. Adverse effects (hyperpigmentation, hypopigmentation, blister, folliculitis) were questioned. The treatment was defined as successful if there was more than 50% hair reduction and an absence of the adverse effects.
Results: There was a positive correlation between hair reduction and number of treatments (r = .402, p < .005). The following side effects were observed: hyperpigmentation (two patients, both in group IV); hypopigmentation (one patient in group IV) and blister (one patient in group IV); folliculitis (two patients in group III and IV). Treatment was successful in 48.3% (28 out of 58) of the treatment sites. The success rate was 25% for ?4 treatments, and 76%, 58%, and 15% for 5, 6, and ?7 treatments respectively (p = .002).
Conclusion: Patients who undergo more treatment sessions achieve a higher rate of hair reduction; although this may be concomitant with an increase in the incidence of adverse effects. The benefit of more laser treatments should be balanced with the risk of occurrence of side effects in each patient.

Objective: To review the results of clinical trials and case series with respect to light source, topical photosensitizing agent, adverse events, efficacy and skin type.
Methods: A non-critical review is presented of a PubMed search for studies examining PDT in the treatment of acne vulgaris.
Results: The authors found 21 clinical trials and case series of various designs. Eight studies employed a split-face design comparing photosensitizer to placebo, no treatment or another photosensitizer. Two trials used three test spots and one control spot per patient. Three studies utilized control subjects receiving no photosensitizer with or without light therapy. All 21 studies reported a reduction in inflammatory lesions and/or a significant improvement in acne. The light sources utilized included blue light, pulsed-dye laser (PDL), intense pulsed light (IPL) and red light. Studies comparing the use of PDT to light therapy alone demonstrated greater improvement in treatment groups pretreated with a photosensitizer.
Conclusion: All studies reported reduction in inflammatory lesions or significant improvement in acne. Several studies confirm a light source combined with photosensitizer is superior to light alone. Adverse reactions including photosensitivity, pustular eruptions, and crusting varied among photosensitizers and light sources. PDT appears to be a useful therapeutic option for acne patients who are recalcitrant to standard treatments and poor candidates for systemic retinoids. Further studies are still needed before a consensus protocol can be established. Additional investigations are needed to establish optimal incubation time, activating light source and frequency of treatment.
Treatment of Poikiloderma of Civatte With AblativeFractional Laser Resurfacing:Prospective Study and Review of the Literature
Emily P. Tierney MD and C. William Hanke MD MPH| |
Background: Previous laser treatments for Poikiloderma of Civatte (PC) (i.e., Pulsed dye, Intense Pulsed Light, KTP and Argon) are limited by side effect profiles and/or efficacy. Given the high degree of safety and efficacy of ablative fractional photothermolysis (AFP) for photoaging, we set out to assess the efficacy of PC with AFP.
Design: A prospective pilot study for PC in 10 subjects with a series of 1−3 treatment sessions. Treatment sessions were administered at 6−8 week intervals with blinded physician photographic analysis of improvement at 2 months post-treatment. Evaluation was performed of five clinical indicators, erythema/telangiecatasia, dyschromia, skin texture, skin laxity and cosmetic outcome.
Results: The number of treatments required for improvement of PC ranged from 1 to 3, with an average of 1.4. For erythema/telangiecatasia, the mean score improved 65.0% (95% CI: 60.7%, 69.3%) dyschromia, 66.7% (95% CI: 61.8%, 71.6%), skin texture, 51.7% (95% CI: 48.3%, 55.1%) and skin laxity, 52.5% (95% CI: 49.6%, 55.4%). For cosmetic outcome, the mean score improved 66.7% (95% CI: 62.6%, 70.8%) at 2 months post treatment.
Conclusion: In this prospective study, AFP was both safe and effective for the treatment of the vascular, pigmentary and textural components of PC. The degree of improvement observed in wrinkling, creping and laxity after AFP has not been reported with prior laser treatments for PC.

Hypertrophic Surgical Scars: A Pilot Study Supriya G. Bellew MD, Margaret A. Weiss MD, Robert A. Weiss MD| |
Result: Mean improvement on a 0 to 3 oint scale was 2.2(55%) after the first LPDL treatment and 3.2 (80%) after the second. Mean improvement was 1.8(45%) after the first IPL treatment and 2.6(65%) after the second. Differnces in improvement between the LPDL and IPL sides were not statisdtically significant. Patients rated IPL. as more painful thatn LPDL. The incidence of post-treatment pupura was lower with IPL.
Conclusions: This pilot study suggests that LPDL and IPL are equally effective in improving the appearance of hypertrophic surgicak scars. IPL offers a movel method of treating scars that minimizes the risk of purpura.

Objectives: To evaluate the effectiveness of pulsed dye laser (PDL), intense pulsed light (IPL) and light-emitting diode (LED) phototherapy for the treatment of moderate to severe acne vulgaris.
Methods: Forty-five patients with moderate to severe acne were randomly divided into 3 equal groups. Group 1 was treated with a PDL, group 2 was treated with IPL, and group 3 was treated with a blue-red combination LED. Treatment was continued until a ≥90% clearance of patient lesions was achieved. Clinical assessments were conducted before starting treatment, at 1 month as a midpoint evaluation, and after the final treatment session.
Results: Patients treated with the PDL reached a ≥90% clearance of their inflammatory lesions after a mean of 4.1±1.39 sessions, while patients treated with IPL required a mean of 6±2.05 sessions. Patients treated with the LED required a mean of 10±3.34 sessions. At the mid-point evaluation, the percent reduction in acne lesions treated with the PDL was 90% or more, in cases of IPL and the LED, the percent reductions were 41.7% and 35.3%, respectively. Laser and light phototherapy sessions were well tolerated with minimal adverse events experienced as being mild and usually self-limiting.
Conclusions: The encouraging results of the present study contributes evidence of phototherapy as useful therapeutic option for treatment of moderate to severe acne, and validates further studies to evaluate treatments with a larger number of patients and for a longer period of follow-up.
Introduction: This study evaluated the efficacy and tolerability of treating mild-to-moderate facial acne using a new, hand-held,
light-emitting diode blue light device in conjunction with a foam cleanser containing 5% glycolic acid and 2% salicylic acid plus a skin
rebuilding serum containing 1.25% salicylic acid, 0.5% niacinamide, 0.08% liposomal-based azelaic acid and superoxide dismutase.
Methods: Volunteers with mild-to-moderate facial inflammatory acne used the blue light device twice daily for eight weeks, plus the cleanser before treatments and the serum after each evening treatment.
Results: Among 33 subjects aged 25–45 years old, 28 completed. In a 3 cm x 5 cm target area receiving a daily dose of ~29 J/cm2, treatment was associated with significant reductions from baseline in the inflammatory lesion count from week 1 onward (P≤.01) and in the non-inflammatory lesion count from week 4 onward (P≤.05). The number of flares was significantly reduced from baseline from week 2 onward (P≤.05), and flare severity and flare redness were significantly reduced from baseline from week 4 onward (P≤.01 and P≤.05, respectively). At week 8, more than 90 percent of subjects reported improvements in their skin’s overall appearance, clarity, radiance, tone, texture and smoothness. In addition, 82 percent were satisfied, very satisfied, or extremely satisfied with the blue light treatment system and 86 percent agreed the treatment system was much gentler than traditional acne treatments.
Conclusion: The blue light treatment system offers effective, rapid, convenient and well tolerated treatment of inflammatory and non-inflammatory acne lesions. The majority of subjects consider it much gentler than traditional acne treatments and it facilitates effective treatment without the need for antibiotic exposure. The blue light treatment system and blue light therapy alone are attractive treatment options for acne vulgaris, both as alternatives to traditional acne treatments and as adjunctive treatments to complement existing therapies.

OBJECTIVE: The objective was to evaluate the efficacy and safety of a dual-wavelength laser device in treatment of neck and facial PWS in a direct side-by-side comparison.
METHODS: Sixteen Chinese patients with neck and/or facial PWSs were enrolled in the study. All lesions were randomly divided into two area, treated area and adjacent untreated area. Five successive treatments using a dual-wavelength laser system (595-nm PDL combined with 1,064-nm Nd:YAG laser) were delivered on treated areas at 4- to 6-week intervals. The adjacent area was not treated as self control. Two blinded dermatologists evaluated the clinical changes by comparing the before and after photos. Erythema index (EI) values were measured with a non-invasive instrument.
RESULTS: After five sessions of treatment, over 62.5% (10/16) patients achieved more than 50% (moderate or significant) improvement. The efficacy maintained at the 3-month follow-up visit. The values of EI on treated area showed a significant decrease. Adverse effects of treated area were limited.
CONCLUSION: Using this split-face module, the dual-wavelength laser system is proved to be effective and well tolerated in treating neck and facial PWSs in Chinese patients. Adverse effects were minimal and acceptable.

Thirty-two consecutive patients of Fitzpatrick skin types I- III underwent 1 to 7 treatments with intense pulsed light. Patients were assessed clinically and photographically. In addition, patients completed a detailed questionnaire regarding their response to treatment.
Following treatment, eighty-three percent of patients had reduced redness, 75% noted reduced flushing and improved skin texture, and 64% noted fewer acneiform breakouts. Complications were minimal and transitory.
It appears that intense pulsed light is an effective treatment for the signs and symptoms of rosacea and represents a new category of therapeutic options for the rosacea patient.

In-Vivo Histological Analysis of a Fractional CO2 Laser System Intended for Treatment of Soft Tissue
Elisabeth Hurliman MD,a Brian Zelickson MD,b Jeffrey Kenkel MDc| |
BACKGROUND: Fractional ablative lasers have been shown to be safe and effective for improving wrinkles, scars, skin texture, and dyspigmentation. However, the exact effects of this technology in vivo on epidermal and dermal skin constituents have not been delineated. This study evaluated the in vivo histological effects over time of treatment with a fractional ablative CO2 system, using different treatment parameters. MATERIALS AND METHODS: Healthy adult volunteers were enrolled in this multicenter clinical study. Study participants, previously scheduled for abdominoplasty, received fractional CO2 laser treatment on the abdomen at a predetermined time prior to surgery. Biopsies were taken at baseline and after CO2 treatment. Morphological and morphometric analyses were performed in the ablated and coagulated tissue areas. RESULTS: Nine healthy adult volunteers were treated. Histologic evaluation showed 800-900 micron diameter zones of ablation and coagulation confined to the upper most layer of the skin in the mode with the greatest fractional skin coverage using Light Mode 30 - 50% (spot diameter of 150 microns, 30-60 millijoules fluence), while ablation to levels of up to 900 microns in depth using the Deep Mode (spot diameter 150 microns, 50-80 millijoules). Healing times of treated tissue varied from 1-day post-treatment with the Light Mode, and up to 10 days post-treatment with the Deep Mode. No remnants of ablation or coagulation were seen after 30 days post CO2 treatment with either mode. There were no adverse events associated with treatments. CONCLUSION: Treatment of the skin using the fractional CO2 device leads to skin resurfacing via ablation and coagulation of the treated area at a depth proportional to the delivered energy. The higher the energy used, the greater the degree of ablation and coagulation in tissue, which can lead to a greater tissue response in terms of fibroblast activity, collagen remodeling, and new collagen formation.

Aging gracefully has taken on a whole new meaning over the past few decades as new aesthetic treatments have been developed and are becoming more sophisticated by the day. The aging process, which is exacerbated by chronic UV exposure, results in dyspigmentation, loss of skin laxity, precancerous and cancerous skin lesions, fat loss and redistribution, and bone resorption. Laser and light devices can be used to treat dyspigmentation, while neuromodulators and soft tissue fillers can be used for rhytides and revolumization. Newer procedures include using resorbable polyglycolide/L-lactide suspension sutures with bidirectional cones for mid face revolumization, deoxycholic acid injections for submental fat reduction, and radiofrequency energy. Certain over-the-counter products can increase the risk of postprocedure bruising, while arnica and bromelain may help decrease this risk. Dermatologists continue to be at the forefront of aesthetic treatments, ready and willing to help the aging population look and feel their best.

Clinical Improvement and Safety of Ablative Fractional Laser Therapy for Post-Surgical Scars: A Systematic Review of Randomized Controlled Trials
Trenton Custis MDa,b and Daniel B. Eisen MDa| |
OBJECTIVE: To identify randomized trials that study the efficacy of ablative fractionated laser therapy for treatment of surgical scars.
METHODS AND MATERIALS: EMBASE, Web of Science, and Pubmed databases were searched for randomized trials with 10 or more surgical wounds. No restrictions were placed on the language of the publications.
RESULTS: Three randomized trials were identified that met the criteria for the review. One study found superior efficacy of ablative fractionated laser treatment of surgical scars compared to pulsed dye laser while the others found equivalent efficacy when compared to dermabrasion or pulsed dye laser. One study found a superior safety profile for ablative fractionated laser treatment over dermabrasion. No studies compared fractionated laser therapy to sham therapy or observation.
CONCLUSIONS: AFL compares well with the scar amelioration techniques of dermabrasion and pulsed dye laser. Additional studies are needed to further contrast AFL to these and other modalities as well as to observation alone.

Background: Traditional full-face resurfacing has been limited to erbium-doped yttrium aluminium garnet (Er:YAG) and carbon dioxide (CO2) lasers. These devices offer wavelength-specific advantages and disadvantages.
Methods: Nine patients were enrolled in a pilot study of a resurfacing system using a 2790-nm erbium:yttrium-scandium-galliumgarnet (Er:YSGG) laser system. Two treatments were carried out 1 month apart over the entire face. Test spots were performed prior to the full-face sessions to determine the optimal fluence for 1-pass laser resurfacing. Biopsies were performed at the time of treatment and at the final follow-up visit one month after the second treatment. Clinical endpoints included changes in pigment dyschromias, wrinkles, and skin tone. All outcomes were graded by blinded observers.
Results: Eight patients completed the 2 treatments. Biopsies showed thermal damage extending as deep as 80 μm below the stratum corneum. Reepithelialization was complete within 4 days. No scarring, post inflammatory hyperpigmentation (PIH), or infections were observed.
Conclusion: A 2790-nm laser can be used for skin rejuvenation with a 4 day recovery window.

Background: While most of the attention regarding skin pigmentation has focused on the effects of ultraviolet radiation, the cutaneous effects of visible light (400 to 700nm) are rarely reported. Objective: The purpose of this study was to investigate the cutaneous pigmentary response to pure visible light irradiation, examine the difference in response to different sources of visible light irradiation, and determine a minimal pigmentary dose of visible light irradiation in melanocompetent subjects with Fitzpatrick skin type III - VI. Methods: The study was designed as a single arm, non-blinded, split-side dual intervention study in which subjects underwent visible light irradiation using LED and halogen incandescent light sources delivered at a fluence of 0.14 Watts/cm2 with incremental dose progression from 20 J/cm2 to 320 J/cm2. Pigmentation was assessed by clinical examination, cross-polarized digital photography, and analytic colorimetry. Results: Immediate, dose-responsive pigment darkening was seen with LED light exposure in 80% of subjects, beginning at 60 Joules. No pigmentary changes were seen with halogen incandescent light exposure at any dose in any subject. Conclusion: This study is the first to report a distinct difference in cutaneous pigmentary response to different sources of visible light, and the first to demonstrate cutaneous pigment darkening from visible LED light exposure. Our findings raise the concern that our increasing daily artificial light surroundings may have clandestine effects on skin biology.

METHODS: Two patients underwent surgery to remove facial skin cancer tumors. The resulting scars after reconstruction of these skin cancer defects on the left cheek (Case 1) and right cheek (Case 2) each received 3 treatments with a fractional ablative laser device (ProFractional-XC, Sciton, Inc., Palo Alto, CA). Treatments were spaced about 1 month apart. Topical anesthetic cream applied 1 hour before treatment minimized patient discomfort during the procedure. Treatment depths ranged from 150 to 200 microns, 2 passes were performed, and coverage per pass was typically 22% and then 11% in the coagulation mode. Results were evaluated by digital photography before the initial treatment, approximately 4-5 weeks after each of the 3 treatments, and at approximately 7 months after the surgical procedures.
RESULTS: The fractional Er:YAG laser device significantly improved postsurgical scar lines in each patient without significant adverse effects. Prior to the laser sessions, these scars demonstrated hypopigmentation, hyperpigmentation, neovascularization, or diminished pore structures compared to the surrounding skin. These pigmentary, vascular or textural issues were all significantly improved by the fractional ablative Er:YAG laser.
CONCLUSION: The ablative fractional laser device of the present report safely minimizes and improves facial scars demonstrating not only textural alterations but also some pigmentary and vascular changes after reconstruction of skin cancer defects.

Background: 308 nm excimer laser phototherapy is efficacious in the treatment of localized psoriasis. Different approaches regarding
dose fluency, number of treatments, and maintenance have been utilized, and there is yet to be a consensus on standard protocol.
Objective: To characterize treatment parameters for 308 nm excimer laser phototherapy.
Methods: We performed a PubMed search for studies describing excimer laser treatment protocol with particular attention to dosage determination, dose adjustment, dose fluency, number of treatments, and maintenance.
Results: Seven prospective studies were found describing the excimer efficacy for psoriasis. All studies determined the initial treatment dose using either the minimal erythema dose (MED) or induration. Fluency ranged from 0.5 MED (low) to 16 MED (high); one study demon- strated that medium to high fluencies yielded better improvement in fewer number of treatments. Fluency adjustments during the course of treatment were important to minimize phototherapy-associated side effects. The use of higher fluencies was reported to result in higher occurrences of blistering. One study implemented a maintenance tapering of dose-frequency phase to better manage psoriasis flare-ups.
Conclusion: The 308 nm excimer laser is an effective therapy for psoriasis regardless of the method used to determine initial dosage, dose fluency, or number of treatments. As its usage as a targeted monotherapy increases, future trials should consider evaluating and modifying these parameters to determine the most optimal management of localized psoriasis. Based on our reviewed studies, there is no consensus for a single excimer laser therapy protocol and as a result, patient preferences should continue to be an important consid- eration for phototherapy regimen planning.

Fractional, Nonablative Q-switched 1,064-nm Neodymium YAG Laser to Rejuvenate Photoaged Skin: A Pilot Case Series
Methods: Seven healthy female subjects (mean ±standard deviation age, 53.8 ± 10.0 years) with visible signs of facial and neck skin aging were treated with fractional, nonablative Q-switched 1,064-nm Nd:YAG laser device (Pixel QS Nd:YAG; Alma Lasers Ltd, Caesarea, Israel). Treated areas were the face, including the periorbital and perioral regions (particularly the upper lip), neck, and chest. Treatments consisted of 3 sessions at 2- to 4-week intervals. Follow-up was performed monthly following the final treatment. The Alexiades-Armenakas Comprehensive Grading Scale of Skin Aging was employed to assess efficacy. Pain ratings were recorded by 10-point visual assessment scoring.
Results: Employing the validated, quantitative grading scale for rhytides of the face and neck, a 0.29 grade improvement, or 11.3% improvement, over baseline grade was observed in the 7-subject cohort that completed follow-up following a mean of approximately 2 treatments at approximately 1-month follow-up. No pain and rapidly resolving minimal erythema were noted in all subjects during treatment.
Conclusion: The results of this pilot case series suggest that the treatment with the fractional, nonablative Q-switched 1,064-nm Nd:YAG laser device significantly improves superficial rhytides. With its outstanding safety, it seems to be particularly suitable for the treatment of sensitive areas, such as the periorbital region, lips, neck, and chest. The Q-switched Nd:YAG laser is a facile, safe, and fast treatment for aesthetic skin rejuvenation.

Treatment of Photoaging With a Dual-Wavelength, 532 nm and 1,064 nm Picosecond-Domain Laser Producing a Fractionated Treatment Beam Using a Holographic Optic
Eric F. Bernstein MD MSE,a Kevin T. Schomacker PhD,b Amit S. Paranjape PhD,b Jayant D. Bhawalkar PhDb| |
BACKGROUND: A dual-wavelength, picosecond-domain, fractionated laser delivering 1,064nm and 532nm laser energy through a holographic optic was investigated for safety and effectiveness at improving the appearance of chronic photoaging. MATERIALS AND METHODS: A total of 27 subjects were enrolled with 24 completing the study, and 14 subjects were treated with 1,064 nm and 10 with 532 nm. The 1,064 nm-treated subjects received 5 monthly treatments while the 532 nm-treated subjects received 4 monthly treatments. Improvement was measured by blinded evaluation of pre- and post-treatment images 12 weeks following the final treatment. Subjects also evaluated treatment effect and side-effects. RESULTS: Blinded reviewers correctly identified the baseline image in 52 of 72 paired images, or 72% of the time, with a mean improvement score of 1.4 using an 11-point rating scale (P less than 0.0001). Post-treatment erythema, mild edema, and petechiae were the only side effects noted. CONCLUSION: The fractionated, picosecond-domain, 532 nm and 1,064 nm laser is safe and effective for improvement of facial photodamage. The laser was well tolerated with mild erythema, edema, and petechiae as the most common side-effects.

Background: A wide variety of laser and light-based therapies have been utilized for acne vulgaris; however, current techniques have been limited by photosensitivity issues or inconsistent results.
Objective: To determine the clinical efficacy and side-effect profile of photopneumatic therapy for the treatment of facial acne vulgaris.
Methods: Twenty adults with mild to severe facial acne vulgaris received 4 successive treatments at 2-week intervals with a combined photopneumatic device (intense pulsed light [IPL]: fluences=3.6-4.2 J/cm2; negative pressure=3 psi). Clinical improvement was evaluated on a quartile grading scale using comparative digital photographs at baseline, and 1 month and 3 months after the final treatment. Acne lesion counts were obtained at baseline, prior to each treatment session, and at the end of the study.
Results: Modest reduction in acne lesion counts and global clinical improvement was seen in the majority of patients. Patients with severe acne experienced the most clinical improvement. Side effects were mild and limited to transient erythema and rare purpura. Most patients experienced acne worsening early in the treatment course.
Conclusion: Photopneumatic therapy is a safe and effective treatment for acne vulgaris. Patients with more severe acne respond best to treatment.

A Difference in Cutaneous Pigmentary Response to LED Versus Halogen Incandescent Visible Light: A Case Report from a Single Center, Investigational Clinical Trial Determining a Minimal Pigmentary Visible Light Dose
Teo Soleymani MD,a Nicholas A. Soter MD,a Lorcan M. Folan PhD,b Nada Elbuluk MD MSc,a Uchenna R. Okereke MD,a and David E. Cohen MD MPHa| |
BACKGROUND: While most of the attention regarding skin pigmentation has focused on the effects on ultraviolet radiation, the cutaneous effects of visible light (400 to 700nm) are rarely reported. In this report, we describe a case of painful erythema and induration that resulted from direct irradiation of UV-naïve skin with visible LED light in a patient with Fitzpatrick type II skin.
METHODS AND RESULTS: A 24-year-old healthy woman with Fitzpatrick type II skin presented to our department to participate in a clinical study. As part of the study, the subject underwent visible light irradiation with an LED and halogen incandescent visible light source. After 5 minutes of exposure, the patient complained of appreciable pain at the LED exposed site. Evaluation demonstrated erythema and mild induration. There were no subjective or objective findings at the halogen incandescent irradiated site, which received equivalent fluence (0.55 Watts / cm2). The study was halted as the subject was unable to tolerate the full duration of visible light irradiation.
CONCLUSION: This case illustrates the importance of recognizing the effects of visible light on skin. While the vast majority of investigational research has focused on ultraviolet light, the effects of visible light have been largely overlooked and must be taken into consideration, in all Fitzpatrick skin types.

Bilateral Axilla Hair Removal Comparing a Single Wavelength Alexandrite Laser With Combined Multiplexed Alexandrite and Nd:YAG Laser Treatment From a Single Laser Platform
Methods: Subjects received four laser treatments at 4-6 week intervals. One axilla was treated with the alexandrite laser alone while the contralateral axilla was treated with multiplexed pulses delivering either a 755 nm/1064 nm pulse or a 1064 nm/755 nm pulse. Efficacy was evaluated through blinded hair counts performed on digital photographs taken two and six months following the final treatment.
Results: Mean hair clearance percentages were 83%, 81%, and 86% for the alexandrite, alexandrite/YAG sequence, and YAG/alexandrite sequence, respectively. Side effects were minimal and did not differ by treatment.
Conclusion: Muliplexed 755 nm/1064 nm and 1,064 nm/755 nm pulses compared favorably with the 755 nm pulses for efficacy and side-effect profile, all being highly efficacious. Further study of the multiplexed pulses in various clinical settings, including refractory hair removal, are indicated.

Background: Due to the hemoglobin-selective wavelength of the 595 nm pulsed-dye laser, it is a device of choice for treating cutaneous
vascular lesions. However, it is less effective and removing dyschromia, which along with hypervascularity is a cardinal sign of cutaneous
photodamage. A novel 607 nm dye laser was developed as a first step in creating a dual-wavelength pulsed-dye laser.
Study Design/Materials and Methods: Twenty-five subjects with dyschromia on the chest due to chronic photodamage were enrolled into an open-label study to explore the safety and efficacy of a 607 nm pulsed-dye laser, with 22 completing the study. Two treatments were administered to the chest, one month apart, with fluences ranging from 3-6 J/cm,2 using a 10 mm diameter spot and pulse duration of 1.5 msec. Cross-polarized digital photographs were taken before and two months following the final treatment and rated for improvement by physicians in a blinded fashion.
Results: Improvement was rated on a five-point scale with no subjects rated as poor (<25%) clearance, three subjects (13.6%) demonstrating fair (26-50%) improvement, seven subjects (31.8%) rated as good (51-75%) improvement, 12 (54.5%) were rated as excellent (76-95%) improvement, while none were rated as outstanding improvement (>95%).
Conclusion: This is the first study of the 607 nm pulsed-dye laser which showed it to be safe and effective for treating dyschromia of the chest due to chronic photodamage, and may in the future expand the ability of the pulsed-dye laser to treat photodamaged skin.

Histological and Clinical Studies on the Effects of Low to Medium Level Infrared Light Therapy on Humanand Mouse Skin
Koichiro Kameyama MD PhD| |
Study Design/Materials and Methods: Ten, 20, or 30 J/cm2 infrared light were irradiated on the human subject’s skin (thigh), while 5, 10, 20, or 30 J/cm2 were used on amelanotic mouse skin. Biopsies were taken and analyzed using hematoxylin and eosin (H&E) and Elastica von Gieson stain.
Results: Ten or 20 J/cm2 infrared light increased the amount of both collagen and elastin in all layers of the dermis without denaturing the collagen in human skin. A higher dose of 30 J/cm2 also increased the amount of collagen and elastin, but denatured the collagen in human skin. (In addition to the thigh, 2 treatments of 10 J/cm2 infrared light improved skin toning and texture on the subject’s face.) In mouse skin, 5 or 10 J/cm2 remarkably increased the amount of both collagen and elastin, and of epidermal cells. Twenty or 30 J/cm2 increased the amount of collagen and elastin and the number of keratinocytes, but caused some vacuolated degeneration of keratinocytes. The presence of denatured collagen was not evident due to the high density of collagen.
Conclusions: This study shows that the denaturation of collagen is not required to increase the amounts of collagen or elastin in vivo in human skin. The activation of the mitochondria as well as the denaturation of collagen may play important roles in infrared phototherapy.

Observations: This article describes a 26-year-old African American woman with moderate infl ammatory facial acne vulgaris. On examination, she had over 15 infl ammatory papules on her face and post-infl ammatory hyperpigmentation. The patient had a history of treatment failure with the following therapies: topical benzoyl peroxide, topical antibiotics, topical retinoids and oral antibiotics. At presentation, the patient was using a combination topical benzoyl peroxide/clindamycin product in the morning and tazoratene gel in the evening without success. The patient was treated with 20% aminolevulinic acid/blue-light photodynamic therapy spaced monthly for a total of four treatments, a once-daily application of hydroquinone 4% cream and her existing topical regimen. The patient reported signifi cant improvement of infl ammatory acne lesions and post-infl ammatory hyperpigmentation following two treatments with photodynamic therapy and was virtually clear of all acne lesions after the third treatment.
Conclusion: Photodynamic therapy is an emerging remedy for patients with acne vulgaris resistant to standard treatment, particularly in patients with skin of color who are more sensitive to post-infl ammatory hyperpigmentation. In this African-American patient, 20% aminolevulinic acid/blue-light photodynamic therapy was effective in treating facial acne vulgaris.

Methods: In a retrospective multicenter study, clinical data were collected from 56 patients with mild to severe acne. Patients had been treated 2 to 4 times with a portable photopneumatic device (Aesthera PPx, Aesthera Corporation, Pleasanton, CA) that delivers broadband light (400 to 1200 nm) to the treatment site via a hand piece. For 11 of the 56 photographs taken before and after PPx treatment.
Results: For the 56 patients, the median physician-rated clearance increased from 50% after a single treatment to 90% after the fourth treatment, whereas the median patient-rated clearance improved form 50% after a single treatment to 78% after the fourth treatment. On a 4-point scale, both physician-rated and patient-rated median overall satisfaction levels increased from a 3 after a single treatment, to 4 after the second, third, and fourth treatments. Clinically significant adverse events were not observed. For the 11 patients evaluated by photography, the median papule and pustule lesion counts decreased from 2 to 0, respectively. Median acne severity (Burton scale) decreased from 2 before treatment to 1 after the final treatment (scale 1-4). Adverse events were limited to mild erythema.
Conclusion: Photopneumatic technology provides a safe and effective treatment of mild to sever acne vulgaris.

Objective: To evaluate clinical efficacy and side effects of photodynamic therapy using topical 5-methyl aminolevulinate and red light for photorejuvenation.
Methods: A randomized, prospective, split-face comparison study of 10 white, adult patients with moderate photodamage, Fitzpatrick skin types 2 or 3, and no occurrence of actinic keratosis was performed. Three treatments using topical methyl aminolevulinate cream, applied for 1 hour on one half of the face and 3 hours on the other half before illumination with red light. A blinded investigator prior to treatment and 2 months after the third treatment evaluated each side of the subject’s faces.
Results: A moderate improvement in fine lines, tactile roughness, and skin tightness was observed in most of the patients, mostly on the 3-hour time side. There were no changes in mottled pigmentation or telangiectasias. Side effects were observed in all subjects (erythema, edema, scaling) mainly in the 3-hour incubation time side.
Limitations: The small number of patients and the lack of placebo group. Conclusion: Methyl aminolevulinic-photodynamic therapy with red light can improve fine lines, tactile roughness and skin tightness in patients with moderate photoaging and no occurrence of actinic keratosis.

METHODS: Five female patients (age range, 30-60) with abdomen striae alba (n=4) and striae rubra (n=1) were enrolled in the study. Skin type distribution among the 5 patients was two type II, one type III, and two type IVs. The device (Accent XL, Alma Lasers Inc.) is a radiofrequency fractional platform (40.68 MhZ) that deploys multiple conical pin electrodes on a moving handheld 6 cogs roller. Four treatments were performed every two weeks with settings based on test spots performed two weeks prior to a full treatment session. Assessment of striae was based on clinical severity of the lesions on a 1-4 scale, with “4” being the most severe. A questionnaire was administered to patients with possible subjective responses ranging from 0-4, with 0 being no improvement and quartiles from 1-4 (1= mild improvement, 2= fair improvement, 3= moderate improvement, and 4= marked improvement, respectively).
RESULTS: Three months after 4 treatments, a mean improvement of 20% was achieved (mean severity score changed from 2.9 to 2.5). Micro-wounds were approximately 200 μm wide on the surface, initially presenting as small gray “dots” and evolving into black dots lasting about 2 weeks. Mean pain was 2/10. Erythema and edema persisted for about one day. No pigmentation abnormalities were observed at the final evaluation. The results from the patient questionnaire revealed a mean score of 2.4/4, thus falling in the range of good to very good.
CONCLUSION: A fractional ablative micro-plasma RF roller device can improve improvement in the appearance of abdomen striae.

Comparison Between Sequentional Treatment With Diode and Alexandrite Lasers Versus Alexandrite Laser Alone in the Treatment of Hirsutism
Laser systems that are commonly used for the treatment of hirsutism include the ruby laser (694 nm), the diode laser (800 nm), the alexandrite laser (755 nm) and the Nd:YAG laser (1084 nm). The diode laser and alexandrite laser are considered effective in treatment of hirsutism in dark-skinned patients. The response of hairs to these laser systems is variable and not complete. In this study, we compared the efficacy of these two laser systems for permanent hair removal. This was a randomized, controlled clinical trial that was performed with women of the age range 15−45 years old. After obtaining informed consent, the samples were randomized into two groups using random allocation software. The first group was treated with alexandrite laser alone (four sessions, two months apart). The second group was treated sequentially with diode laser for the first two sessions and alexandrite laser for the next two sessions. Overall, 111 patients (57 patients in the alexandrite laser group and 54 patients in the sequential diode-alexandrite laser group) were evaluated. There was no significant difference regarding mean of hair reduction between the two groups during the courses of treatment. Except for the first session, there was no significant difference regarding percent of patient satisfaction between the two groups (P value >0.05). Comparison between the two groups showed no significant difference one month, three months and six months after the last treatment (P value >0.05). Regarding the results of our study, there is no significant difference between sequential treatment with diode and alexandrite lasers versus alexandrite laser alone in the treatment of hirsutism. We suggest that in further studies, the efficacy of sequential treatment with other laser systems is evaluated against single treatment methods.

The Erbium Micropeel: A Prospective, Randomized Trial of the Effects of Two Fluence Settings on Facial Photoaging
Brian Somoano MD, Basil M. Hantash MD PhD, Edgar F. Fincher MD PhD, Peggy Wu MD, Hayes B. Gladstone MD| |
Methods: Forty-six subjects with mild-to-moderate facial dyschromia and rhytides were evenly randomized to two Er:YAG treatment arms. Patients in the lower fluence (LF) (2.5 J/cm2) and higher fluence (HF) (3.8 J/cm2) groups each received three one-pass, full-face treatments one month apart. Patient and investigator assessments of rhytides, dyschromia and global appearance were performed at baseline and at four, eight and 20 weeks using a nominal scale from 1–4. Adverse events and patient satisfaction were also evaluated.
Results: Patient scores showed rhytid improvement only with HF treatments. Investigator scores at three months post-treatment showed dyschromia was significantly improved in both study arms, with a 24 and 36 percent reduction for the LF and HF groups, respectively. Global appearance scores improved by 25 and 32 percent, respectively. A trend towards greater post-procedure erythema and time-to-erythema resolution was observed in the HF group. Mild peeling was the most common adverse event. Individuals who underwent LF treatments were more likely to pursue future treatments.
Conclusion: Both settings resulted in moderate but significant improvement in dyschromia, although only HF treatment improved rhytides. The decreased downtime of LF treatments made this the preferred choice of patients.

Neocollagenesis in Deep and Superficial Dermis by Combining Fractionated Q-Switched ND:YAG 1,064-nm With Topical Plant Stem Cell Extract and N-Acetyl Glucosamine: Open Case Series
Kavita Beri MDa and Sandy S. Milgraum MDb| |
METHOD: Six healthy females (Skin types III - V) were selected for the study with mean average age of 56 years +/- 11 years. The rhytides on the face and neck were assessed using a comprehensive grading scale. Patients were then divided into two groups, one received only laser treatment with the fractionated QSW 1,064 nm laser and the other group received combined treatment with the laser and topical. Patients were assessed again at 4 and 8 weeks.
RESULTS: We observed an enhanced anti-aging effect of the laser in the patients with combined treatment.
DISCUSSION: Understanding the effect of this novel laser therapy on human stem cells and investigating the basis of its synergistic effect with plant stem cell extract and NAG will lead us to better understand stem cell activity. Non-ablative tissue regeneration is the next step in providing optimal anti-aging treatments.

A Systematic Review of Light Emitting Diode (LED) Phototherapy for Treatment of Psoriasis: An Emerging Therapeutic Modality
Derek Ho BS,a,b Eugene Koo MS,a,b Andrew Mamalis MD MS,a,b and Jared Jagdeo MD MSa,b,c| |
Background: Psoriasis is a chronic, inflammatory skin condition. The economic burden of psoriasis is approximately $35.2 billion in the United States per year, and treatment costs are increasing at a higher rate than general inflation. Light emitting diode (LED) phototherapy may represent a cost-effective, efficacious, safe, and portable treatment modality for psoriasis.
Objective: The goal of our manuscript is to review the published literature and provide evidence-based recommendations on LED phototherapy for the treatment of psoriasis.
Methods & Materials: A search of the databases Pubmed, EMBASE, Web of Science, and CINAHL was performed on April 5, 2016. Key search terms were related to psoriasis and LED-based therapies.
Results: A total of 7,793 articles were generated from the initial search and 5 original articles met inclusion criteria for our review. Grade of recommendation: B for LED-blue light. Grade of recommendation: C for LED-ultraviolet B, LED-red light, and combination LED-near-infrared and LED-red light.
Conclusion: We envision further characterizing the effects of LED phototherapy to treat psoriasis in patients may increase adoption of LED-based modalities and provide clinicians and patients with new therapeutic options that balance safety, efficacy, and cost.

OBJECTIVE: We investigated the safety and efficacy of a fractionated 1927nm non-ablative thulium laser for the treatment of photo-induced pigmentation.
METHODS: Prospective multi-center study of subjects with clinically identifiable photopigmentation. The study protocol was approved by BioMed Institutional Review Board (San Diego, CA). Subjects received two treatments with a non-ablative 1927nm fractionated thulium laser (Fraxel Dual 1550/1927 Laser System, Solta, Hayward CA), energy level of 10mJ, coverage of 40% and 4-6 passes. Subject pain, erythema and edema were recorded immediately after treatment. Two dimensional photography was obtained before each treatment and at one and three month follow up visits. Independent blinded physician assessment was performed evaluating overall improvement in appearance as well as pigment specific improvement.
RESULTS: Forty men and women, ages 30 to 80 years, Fitzpatrick skin types I-IV, with photo-induced facial pigmentation were enrolled and treated, and 39 completed the three month follow up visit. Mean pain sensation for subjects during laser treatments was reported to be 4.3 on a 10-point scale. Mean scores for erythema, edema, and skin roughness throughout all treatments indicated moderate erythema, mild edema and mild skin roughness. Assessment of overall improvement was graded as moderate to very significant in 82% of subjects at one month and in 69% of subjects at three months after the second treatment. Assessment of lentigines and ephelides demonstrated moderate to very significant improvement in approximately 68% of subjects at the one month and in 51% of subjects at three months after the second treatment. Independent blinded physician assessment of randomized photography also demonstrated a durable response at three month follow up visit. Treatment was well tolerated and no serious adverse events related to treatment were observed or reported. Study limitations included a limited number of male subjects, lack of Fitzpatrick skin types V and VI, and decrease in improvement at 3 months post-treatment.
CONCLUSIONS: Two treatments with a 1927nm non-ablative fractionated thulium laser produced moderate to marked improvement in overall appearance and pigmentation with high patient satisfaction. The response to treatment was maintained at one and three months follow up.

Topical Liposomal Rose Bengal for Photodynamic White Hair Removal: Randomized, Controlled, Double-Blind Study
Nevien Samy PhDa and Maha Fadel PhDb| |
OBJECTIVE: To investigate if repetitive sessions of photodynamic therapy (PDT) using external application of liposomal Rose bengal (RB) photosensitizer followed by intense pulsed light (IPL) exposure enables removal of gray and white hair.
MATERIALS and METHODS: Rose bengal loaded in liposomes (LRB) was constructed, prepared in hydrogel, and was studied for some pharmaceutical properties. Penetration and selective hair follicle damage in mice skin were studied. Topical gel containing LRB was used for treating fifteen adult females who were complaining of facial white terminal hair. Unwanted facial hair was treated for three sessions at intervals of 4–6 weeks using intense pulsed light (IPL). At each session, the treatment area was pre-treated with topical LRB gel, while a control group of another 15 patients applied placebo gel before IPL treatment. Evaluations included hair regrowth, which was measured 4 weeks after each treatment session and at 6 months follow-up by counting the number of terminal hair compared with baseline pretreatment values. Treatment outcomes and complications if any were also reported.
RESULTS: Average hair regrowth in the LRB group was 56% after 3 treatment cycles. After six-months follow up, average terminal hair count compared with baseline pretreatment showed 40% reduction and no recorded side effects. A significant difference (P<0.05) was seen compared with the control group; the clinical results were promising.
CONCLUSIONS: Photodynamic hair removal using rose bengal-encapsulated liposomal gel in combination with IPL treatment showed significant efficacy in the treatment of white hair compared with a control group.

Methods: Four patients with sebaceous hyperplasia underwent a test spot treatment followed by 2 full treatment sessions using the 1,720-nm laser. Photos were taken before treatment, at each treatment session, and 3 months following the last treatment. Pretreatment photographs and 3-month follow-up photographs were compared to assess efficacy.
Results: Four weeks after the final treatment, 3 dermatologists blinded to the date of the photographs and uninvolved with the study evaluated the photos and scored them based on a global assessment comprised of: 1) lesion diameter, 2) lesion height, and 3) lesion color. Many of the lesions resolved almost completely after a single treatment, and no additional treatment was required. Overall, there was a reduction in the color, diameter, and height of the lesions. Crusts were noted by all patients and resolved within 10 days.
Conclusion: The use of this novel device that exploits the intrinsic selectivity of 1,720 nm achieved nearly complete clearance of sebaceous hyperplasia lesions without depressions or scarring. Complete heating of the sebaceous gland and sparing of the surrounding skin offered by this device resulted in clinically apparent improvement with a minimum of adverse effects.

Fractional Ablative Laser Followed by Transdermal Acoustic Pressure Wave Device to Enhance the Drug Delivery of Aminolevulinic Acid: In Vivo Fluorescence Microscopy Study
Jill S. Waibel MD,a Ashley Rudnick,a Carlos Nousari MD,b and Dhaval G. Bhanusali MDc| |
METHODS: Five patients were treated and biopsied at 4 treatment sites: 1) topically applied aminolevulinic acid (ALA) alone; 2) fractional ablative CO2 laser and topical ALA alone; 3) fractional ablative CO2 laser and transdermal acoustic pressure wave device delivery system; and 4) topical ALA with transdermal delivery system. The comparison of the difference in the magnitude of diffusion with both lateral spread of ALA and depth diffusion of ALA was measured by fluorescence microscopy.
RESULTS: For fractional ablative CO2 laser, ALA, and transdermal acoustic pressure wave device, the protoporphyrin IX lateral fluorescence was 0.024 mm on average vs 0.0084 mm for fractional ablative CO2 laser and ALA alone. The diffusion for the acoustic pressure wave device was an order of magnitude greater.
CONCLUSION: We found that our combined approach of fractional ablative CO2 laser paired with the transdermal acoustic pressure wave device increased the depth of penetration of ALA.

OBJECTIVE: The objective of this review was to describe the various surgical, laser, and alternative therapies available for vitiligo. A literature review was conducted through Pubmed and Ovid using the search terms "Vitiligo treatment”, “Vitiligo surgery”, “Vitiligo laser”. Since no articles were available about needling on both Pubmed and Ovid using the search criteria, individual articles were sought out through Google.
RESULTS: The literature review yielded many possible surgical interventions including autologous mini-punch grafting, suction epidermal blister grafting, split-thickness grafting, and cultured and noncultured melanocyte keratinocyte transfer. Laser options included the helium-neon and xenon-chloride lasers, with tattooing and needling serving as other options. While all the above techniques can provide improvement to pigmentation in vitiliginous patches, physician comfort and experience are important factors with regards to outcome. Our case series of four patients treated with the needling method yielded favorable results, with repigmentation rates ranging from 25-50%, with one patient having 90% repigmentation.
CONCLUSION: There are many surgical, laser, and alternative treatment options available for vitiligo when conventional medical therapy fails or for use in conjunction with medical therapies. Autologous mini punch grafting and needling both have minimal equipment requirements and are easy to learn. Physician experience and comfort play a large role in outcome and availability of services.

Study Design: A total of twenty subjects with chronic photodamage were enrolled in this study. Subjects received a maximum of four full-face treatments at an average fluence of 9.5 J/cm2 at 1,320 nm and 2 J/cm2 at 1,450 nm, delivered sequentially using forced-air cooling, at monthly intervals. Digital photographs were taken two months following the final treatment and compared to pre-treatment photographs by two blinded physician observers.
Results: Improvement in photodamage, overall appearance, wrinkles, hyper-pigmentation, enlarged pores, and sagging skin was rated by blinded physician evaluation of digital photographs as being in the 25-50 percent range. Subjective ratings averaged improved for all criteria that were evaluated, including wrinkles, enlarged pores, redness, sagging skin and hyper-pigmentation.
Conclusions: The multiplexed 1,320 nm and 1,440 nm fractionated laser improves cuta/neous photodamage as assessed by objective and subjective criteria.

Objectives: To determine patient satisfaction and complications with long-pulsed Nd:YAG laser assisted hair removal in dark-complexioned skin individuals from the patient's point of view.
Patients/Methods: A survey questionnaire was administered to subjects with Fitzpatrick skin type VI between the ages of 21-70 years who had been treated with long-pulsed Nd:YAG for unwanted hair. Questions were comprised of those related to satisfaction and complications from treatment with LHR. Satisfaction was recorded on a linear analogue scale (LAS=not at all satisfied; 100=extremely satisfied).
Results: Fifty patients (female 41, male 9) completed the survey. All patients were satisfied with Nd:YAG LHR treatment with the mean satisfaction score of 84.2. All patients favor LHR treatment as compared to alternative methods. The majority of patients (79.3%) who had completed six or more LHR treatments were removing their hair less frequently than before LHR treatment. Hyperpigmentation after treatment was noted in three patients (6%), which lasted for 3-10 days. No hypopigmentation, blistering, or scarring was observed. All patients completing the study would recommend LHR for patients with unwanted hair with the mean recommendation score of 91.5.
Conclusions: Nd:YAG laser-assisted hair removal gives a high rate of patient satisfaction in terms of hair reduction with minimal complication among subjects of color.

Treating Onychomycoses of the Toenail: Clinical Efficacy of the Sub-Millisecond 1,064 nm Nd: YAG Laser Using a 5 mm Spot Diameter
Background: Onychomycosis is a relatively common fungal infection. Current treatments have limited applicability and low cure rates.
Recently introduced laser therapy has shown to be a safe and effective treatment for onychomycosis. In this study, we evaluate a submillisecond Nd:YAG 1,064 nm laser for treating onychomycoses of the tonail.
Methods: Thirteen subjects (9 female, 4 male) with 37 affected toenails received 1 to 3 treatments 4 and/or 8 weeks apart with a sub-millisecond 1,064 nm Nd:YAG laser. Diagnosis of onychomycosis was confirmed with microscopy. Average follow-up time was 16 weeks post-final treatment. Photos were taken and degree of turbidity was determined using a turbidity scale (ranging from "0 = clear nail" to "10 = completely turbid nail") at each visit. Improvement in turbidity was determined by comparison of turbidity scores at baseline and 16-week follow-up on average. Efficacy was assessed by an overall improvement scale (0 to 4), which combined improvement in turbidity scores and microscopic examination. Overall improvement was classified as "4 = complete clearance" if the turbidity score indicated "0 = clear nail" accompanied by a negative microscopic result. No microscopic examination was performed unless the turbidity score showed "0 = clear nail."
Results: Treatments were well tolerated by all subjects and there were no adverse events. Of the 37 toenails treated, 30 (81%) had "moderate" to "complete" clearance average of 16 weeks post-final treatment. Nineteen toenails (51%) were completely clear and all tested negative for fungal infection on direct microscopic analysis. Seven (19%) toenails had significant clearance and four (11%) had moderate clearance.
Conclusions: The preliminary results of this study show this treatment modality is safe and effective for the treatment of onychomycosis in the short term. Additional studies are needed to more fully assess the clinical and mycological benefits as well as optimize the treatment protocol and parameters.

Treatment of Hidradenitis Suppurativa by Photodynamic Therapy With Aminolevulinic Acid: Preliminary Results
Eric S. Schweiger MD,a Christy C. Riddle MD,b Daniel J. Aires MDb| |
Background: The current standard of care for hidradenitis suppurativa (HS) includes antibiotics (oral/topical), retinoids (oral/topical)
and intralesional steroids and is unsatisfactory. Photodynamic therapy (PDT) with 20% 5-aminolevulinic acid (ALA) has been used
"off label" to treat acne vulgaris and may hold promise as a therapy for HS. This open-label, non-blinded study investigated the efficacy
and safety of ALA PDT for the treatment of HS using two blue light sources and intense pulsed light (IPL) for photoactivation.
Methods: Twelve subjects with active HS enrolled to undergo ALA PDT once weekly for four weeks with follow-up visits 4, 8, and 12 or more weeks later. Nine subjects completed the study through the week 8 follow-up visit. Lesions were counted at each treatment visit at week 4, week 8 and at the final week.
Results: Mean lesion counts were 11.25 at baseline, 6.5 at 4 weeks (50.8% reduction), and 7.5 at 8 weeks (29.9% reduction). Mean Global Severity Scores were 2.2 at baseline, 1.5 at 4 weeks, and 1.8 at 8 weeks. Mean DLQI scores were 17.3 at baseline, 13.1 at 4 weeks (27.2% improvement), 14.00 at 8 weeks (19.3% improvement) and 14.0 (19.3% improvement) at the final week (16-62 weeks). Three subjects (25%) had complete clearance and no active lesions 4 weeks after the final treatment. Treatments were more tolerable for subjects treated with blue light than with IPL.
Conclusion: ALA PDT may be a safe and effective treatment of hidradenitis suppurativa.

Randomized, Double-Blind, Split-Face Study Evaluating Fractional Ablative Erbium:YAG Laser-Mediated Trans-Epidermal Delivery of Cosmetic Actives and a Novel Acoustic Pressure Wave Ultrasound Technology for the Treatment of Skin Aging, Melasma, and Acne Scars
Macrene Alexiades MD PhDa,b| |
AIM: Evaluate the safety and efficacy of a novel acoustic pressure wave ultrasound device following fractional ablative Er:YAG 2940-nm laser (FELR) and topical agents for rhytids, melasma, and acne scars.
STUDY DESIGN: Randomized, blinded, parallel group split-face side-by-side, controlled study evaluating FELR and topical anti-aging and anti-pigment agents to entire face succeeded by ultrasound to randomized side. Fifteen subjects were enrolled to three treatment arms:rhytids, melasma, and acne scars. Two monthly treatments were administered with 1, 3, and 6 month follow-up. Efficacy was assessed by Comprehensive Grading Scale of Rhytids, Laxity, and Photoaging by Investigator and two blinded physician evaluators. Subject assessments, digital photographs, and reflectance spectroscopic analyses were obtained.
RESULTS: Rhytid severity was reduced from a mean of 3.25 to 2.60 on the 4-point grading scale. Spectrophotometric analysis demonstrated increases in lightness (L*) and reductions in redness (a*) and pigment (b*), with greater improvements on the ultrasound side as compared to FELR and topicals alone. Moderate erythema post-treatment resolved in 7 days and no serious adverse events were observed.
CONCLUSION: In this randomized, paired split-face clinical study, FELR-facilitated TED of topical anti-aging actives with ultrasound treatment is safe and effective with improvement in rhytids, melasma, and acne scars. Statistically significant greater improvement in pigment levels was observed on the ultrasound side as compared to FELR-TED and topical agents alone.

Ablative Fractionated CO2 Laser Resurfacing for the Neck: Prospective Study andReview of the Literature
Emily P. Tierney MD and C. William Hanke MD MPH| |
Design: A prospective pilot study for neck resurfacing in 10 subjects with a series of one-to-three treatment sessions. Treatment sessions were administered at six-to-eight week intervals with blinded physician photographic analysis of improvement at two months post-treatment. Blinded physician photographic evaluation was performed of four clinical indicators, skin texture, skin laxity, rhytides and overall cosmetic outcome.
Results: The number of treatments required for improvement of neck texture and laxity ranged from 1–3, with an average of 1.4. For skin texture, the mean score improved 62.9% (95% CI: 57.4%, 68.4%), skin laxity, 57.0% (53.2%, 60.8%), and rhytides, 51.4% (48.3%, 54.5%). For overall cosmetic outcome, the mean score improved 59.3% (55.1%, 63.5%) at two months post treatment.
Conclusion: In this prospective study, AFP was both safe and effective for the treatment of neck laxity, rhytids and skin texture. The degree of improvement observed in wrinkling, texture and laxity after AFP coupled with the benign side effect profile has not been reported with previous trials of ablative laser resurfacing of the neck.

A Retrospective Chart Review to Assess the Safety of Nonablative Fractional Laser Resurfacing in Fitzpatrick Skin Types IV to VI
Charlotte M. Clark MD MS, Jonathan I. Silverberg MD PhD MPH, and Andrew F. Alexis MD MPH| |
METHODS: This is a retrospective review of medical records for patients with SPT IV to VI who were treated with a 1,550 nm erbium-doped fractional nonablative laser (Fraxel Re:Store SR 1550; Solta Medical, Hayword, CA). Data were collected from patient charts and the clinic laser logbook from January 2008 to January 2012. The frequency of treatment-associated postinflammatory hyperpigmentation (PIH) and treatment settings used were evaluated.
RESULTS: A total of 115 total laser sessions (45 patients) were included in our analysis. Five of the sessions (4%) were accompanied by PIH, 2 of which occurred in a single patient. Only 1 episode of PIH lasted longer than 1 month (2 months). Two of the 5 cases had only transient PIH (≤7 days), one of which was reported by the patient and not clinically evident on examination.
CONCLUSION: The 1,550 nm erbium-doped fractional laser is well tolerated in SPT IV to VI. Fractional laser resurfacing, with the settings used and pretreatment and posttreatment hydroquinone 4% cream, was associated with a low risk of PIH in darker skin types.

Laser hair removal, previously contraindicated in patients with ethnically dark (phototypes IV-VI) or sun-tanned skin, is now recognized as a safe and effective method of permanent hair reduction in all patients. Longer wavelengths, conservative fluences, longer pulse durations and appropriate cooling methods are necessary to minimize untoward side effects and maximize efficacy. The longer wavelength Nd:YAG laser is considered safest in treating darker skin of color. An added benefit of laser epilation is that side effects of conventional hair removal such as pseudo-folliculitis barbae and post inflammatory dyspigmentation, more commonly seen in skin of color, may also respond favorably to the laser, thus increasing the potential for patient satisfaction.

Methods: Clinical studies were conducted on a range of surgical and post-traumatic scars with a 1540 nm erbium:glass fractional laser varying energy, pulse widths, treatment passes, and number of treatments. A histological study was conducted on a postsurgical scar to follow the time course of healing post-treatment and the impact of the fractional treatment on normalization of scar tissue, as compared to baseline histology of the scar.
Results: Histologic findings demonstrated rapid re-epithelialization of the epidermis within 72 hours of treatment. Remodeling of scar tissue with renewal and reorganization of collagen fibers in the dermis was noted two weeks post-treatment. Clinical subjects, with Fitzpatrick skin types II–V, received three to seven treatments with microbeam energies up to 60 mJ/μb and five passes. Relative to baseline, 73% of treated scars improved 50% or more and 43% improved 75% or more. Side effects included mild swelling (95% of subjects), erythema (94%) and purpura (5%), which all resolved within two to three days. Downtime was minimal-to-none for all subjects.
Conclusion: These data illustrate the safety and efficacy of the 1540 nm erbium:glass fractional laser in the treatment of surgical and post-traumatic scars. Practitioners can vary energy and microbeam density in order to tailor the treatment to reflect the individual scar characteristics.

Assessment of the Mobile Delivery of InfraredLight (1100-1800 nm) for the Treatment of Facialand Neck Skin Laxity
Macrene Alexiades-Armenakas MD PhD| |
Objective: This prospective study assesses the safety, efficacy, and pain profile of the application of infrared light with a mobile delivery method for the treatment of facial and neck skin laxity as assessed by a tested, quantitative grading scale.
Methods: In this study, 22 female subjects (aged 40-75 years; Caucasian and Asian ancestry) with a clinically observable excess of laxity (minimum grade 2 out of 4) on the face received 1 to 3 treatments with incoherent infrared (1100-1800 nm) light at 2-week to 4-week intervals. Each light pulse was administered in a mobile continuous fashion within a localized area measuring approximately 1 handpiece tip-width laterally and vertically. A series of 4 to 5 pulses were administered across small grid areas, followed by 6 to 8 passes to each grid area, totaling approximately 300 to 450 pulses per treatment. Each mobile pulse was delivered at fluences of 45 to 46 J/cm2 to the face, 45 J/cm2 to the mandible, and 44 J/cm2 to the neck. Clinical results were evaluated employing a comprehensive 4-point grading scale from photographs at baseline, and the 1-month and 3-month follow-up visits after the final treatment. Pain ratings were evaluated by visual analog scale (VAS) gradings and patient questionnaire immediately following treatment.
Results: All subjects completed and responded to treatment. The mean treatment number was 2.1 (+/- 0.9) and the mean follow-up interval was 1.9 (+/- 1) months. The quantitative evaluations demonstrated: a mean baseline laxity grade of 2.9 +/- 0.5 and mean posttreatment laxity grade of 2.5 +/- 0.6; and a mean difference in prelaxity grades versus postlaxity grades of 0.4 +/- 0.3 (95% CI; 0.2540- 0.5415). The data demonstrated a statistically significant difference between before and after measurements (P<.0001) and a mean percent improvement in laxity grading scores of 14.1 +/- 11.3%. The treatment discomfort was rated as a mean of 0.7 (+/- 0.6) on a VAS grading scale (0 to 10). By patient questionnaire, sensation during the treatment was rated as painless by 100% of patients and rare (<5) transient moments of heat-related pain sensation were reported by 18% of patients. None of patients reported the procedure as painful or as sensing frequent (>5) or persistent heat-related pain sensation during the treatment. Other side effects included minimal erythema which resolved within 1 to 3 hours. No crusting, dyspigmentation, or scarring was observed.
Conclusion: This prospective clinical study with quantitative grading of laxity and VAS pain scores demonstrated that mobile delivery of infrared light appears to be safe, clinically effective, and painless in reducing facial and neck laxity. The mobile infrared light delivery allowed for delivery of approximately 30% higher fluence dosages and increased passes to each pulse area. The clinically observable and quantified decreases in skin laxity following treatment were statistically significant.

Background: Use of coal tar with narrowband (NB) ultraviolet B (UVB) light (the Goeckerman regimen) is an effective treatment for plaque psoriasis that has become impractical in outpatient care mainly due to the inconvenience and aesthetic concerns of coal tar.
Objective: This study evaluated the safety, efficacy, and convenience of adding a novel LCD (coal tar) solution to standard NB-UVB phototherapy in adults with chronic plaque psoriasis.
Methods: Patients applied LCD solution to half-body twice daily at home and received outpatient full-body NB-UVB light therapy 3 times a week for up to 12 weeks. A blinded investigator graded psoriasis severity of body halves and bilateral target lesions and monitored adverse reactions. Patients rated their psoriasis symptoms and LCD solution aesthetics.
Results: NB-UVB + LCD therapy reduced the median time to clearance or minimal disease in at least 50% of the population by 3 weeks (4 weeks with NB-UVB + LCD versus 7 weeks with NB-UVB alone). A statistically superior clinical response was observed by the end of week 4 with NB-UVB + LCD versus NB-UVB alone (P < 0.05) for: PGA, target lesions, ESI scores, and patient-reported symptoms.
Conclusion: Incorporating an at-home regimen with a novel LCD solution into outpatient NB-UVB light therapy is safe, convenient, effective, and can improve psoriasis more quickly than NB-UVB light therapy alone.
Skin Rejuvenation in Asian Skin: The Analysis of Clinical Effects and Basic Mechanisms of IntensePulsed Light
Yujie Feng, Junying Zhao, Michael H. Gold MD| |
Objectives: The objective of this clinical trial was to evaluate the effects and the mechanism of action of an IPL by comparing clinical photographs and biopsy results before and after treatment.
Methods: A total of 58 patients were treated using a new IPL device. Clinical photographs were taken before treatment and compared to those taken 3 weeks after the treatment. Also, 4 cases had pathological analyses of tissues that were stained by haematoxylin-eosin and Uana orcein. Immunohistology of human collagen of types 1 and 3 and quantitative analyses of elastin and collagen were performed by a poly-functional digital image light microscope; a transmission electron microscope was used for 2 of the cases to look for additional changes.
Results: After 3 treatments, 62.1% of the patients showed improvement in wrinkles and skin texture. Pigmentation improved in 84.6% of the patients, and a reduction in telangiectasis was seen in 81.25% of the patients. Pathological examination showed that both type 1 and type 3 collagens increased following treatment, but elastin content decreased; however, the elastin fibers were arranged more neatly. In the transmission electron microscope study, the amount of fibroblast activity increased, the fibroblasts were more active, and there were more collagen fibers neatly rearranged within the stroma.
Conclusion: Clinical and pathological studies demonstrated that the IPL was effective in improving wrinkles and skin texture. The mechanism of action may be through the increasing activity of the fibroblasts, hyperplasia of the fibroblasts, and rearrangement of both collagen and elastin within the stroma.

A Randomized, Blinded, Bilateral Intraindividual, Vehicle-Controlled Trial of the Use of Photodynamic Therapy With 5-Aminolevulinic Acid and Blue Light for the Treatment of Actinic Keratoses of the Upper Extremities
Background/Objective: Actinic keratoses (AKs) on the upper extremities are difficult to treat. This study compares the efficacy and tolerability of photodynamic therapy (PDT) using 20% 5-aminolevulinic acid solution (ALA) and blue light versus ALA vehicle and blue light for the treatment of AKs of the dorsal hand and forearm.
Methods: Subjects were treated twice at an eight-week interval by ALA with blue light on one hand and forearm and with ALA vehicle and blue light on the contralateral hand and forearm. ALA incubation time was two hours under occlusion. Efficacy and tolerability were compared.
Results: The mean lesion count reductions (58.4±22.2% and 24.8±20.6% four weeks after the second treatment for the ALA and vehicle-treated sides, respectively) differed significantly (P=0.0004). Eleven of 15 subjects (73%) in the ALA-treated side achieved at least 50 percent reduction in lesion count compared to only two subjects (13%) in the vehicle-treated side four weeks after the second treatment. The difference was significant (P=0.0143). Photodamage grade reduction was also significant (P=0.0309) after the second treatment. Subject satisfaction was moderate to very satisfied (86.7%) on the ALA-treated side. Transient adverse events were significantly greater on the ALA-treated side for erythema (P=0.0011), edema (P=0.0199) and stinging and burning (P=0.0016) 48 hours after the first treatment.
Conclusions: Two sessions of PDT using ALA with blue light is a moderately effective, well-tolerated treatment of actinic keratoses of the dorsal hand and forearm.

Treatment of Nodules Associated With Port Wine Stains With CO2 Laser: Case Series and Review of the Literature
Emily P. Tierney MD, C. William Hanke MD MPH| |
Objective: To search the MEDLINE database and review literature on the treatment of PWS and present 2 cases of adults with PWS, complicated by hypertrophic and nodular lesions, treated successfully with CO 2 laser.
Results: Two patients with PWS, with nodular and hypertrophic areas, were treated with CO 2 laser. With the ﬁrst patient, improve- ment of 90% or greater was noted in the 14 discrete nodules present within the PWS in a V2 distribution. At baseline, ectropion of the lower eyelid was noted which resolved completely after CO 2 laser. With the second patient, improvement was noted as 90% or greater in the 40 of 51 discrete nodules present within the PWS extending across the right V1-V2 distribution.
Conclusion: Carbon dioxide ablative laser resurfacing is safe and highly effective in the treatment of the nodular and hypertrophic components of PWS. Future treatment of PWS will likely involve a hybrid approach of utilizing nonablative lasers of varying wave- lengths and pulse durations and treatment with novel laser devices, with the goal of early treatment to prevent progression of PWS to disﬁguring lesions.

OBJECTIVE: To use various methods of photography including standard photography, cross polarized light, parallel polarized light and ultraviolet passing photography to assess which method most effectively captures skin features such as texture, pigment, and/ or vascularity.
METHODS: A prospective analysis comparing advanced photographic techniques including standard photography, polarized light photography, cross-polarized light photography and ultraviolet light passing photography. The photos were then evaluated and scored by two experts and a blinded observer to characterize the differences visualized in each type of photography compared to standard photography in terms of subsurface skin features, hypopigmentation, hyperpigmentation, and rhytids.
RESULTS: 9 subjects completed the study. Overall, of the 3 photographic methods compared to standard photography, UV passing most enhanced the visualization of subsurface features and hypopigmentation, with increased hyperpigmentation as well. Enhancement of these features made UV passing best for capturing photodamage. Cross-polarized photography was best for visualizing hyperpigmentation, but also heightened visualization of hypopigmentation and subsurface features such as vascularity. Parallel-polarized photography enhanced visualization of skin texture.
CONCLUSIONS: These methods of photography show a quantifiable and reproducible selective ability to evaluate and document elements such as skin texture, vascularity, and pigmentation. Each of these techniques has unique properties that can add to the precision of the clinical evaluation and can be of particular value to providers of cosmetic procedures where photo documentation has become increasingly important in providing an objective means of evaluating outcomes.

Comparison of the Efficacy of Long-Pulsed Nd:YAG Laser Intervention for Treatment of Onychomycosis of Toenails or Fingernails
Yan Li MD, Sisi Yu MS, Jing Xu MS, Ruina Zhang MS, and Junying Zhao BS| |
METHODS: One hundred and twelve affected fingernails or toenails in 37 patients with onychomycosis were randomized into Group 1 (22 patients with 50 affected fingernails) and Group 2 (15 patients with 62 affected toenails). These patients were further classified into three subgroups (Grade II, III, and IV) according to Scoring Clinical Index of Onychomycosis. All the affected nails were treated with long-pulse Nd:YAG 1064 nm laser intervention, once weekly, for continuous weeks, and were followed up for 24 weeks.
RESULTS: The response rates at weeks 8, 16, and 24 were 0, 0 and 52%, respectively, for Group 1, and 10, 32 and 71% for Group 2. The inter-group difference in efficacy was statistically significant (P<0.05). Even in the same subgroup, the response rate of Group 2 was higher than that of Group 1.
CONCLUSIONS: The efficacy of long-pulsed Nd:YAG 1064 nm laser intervention against affected toenails is superior to that against fingernails. It is also effective for treatment of onychomycosis with different severity.

Fractional CO2 Laser Treatment vs Autologous Fat Transfer in the Treatment of Acne Scars: A Comparative Study
Omar A. Azzam MD a, Ahmed T. Atta MDb, Rehab M. Sobhi MD, and Pakinam I.N. Mostafa MSca| |
Objective: To compare fractional CO2 laser treatment and fat grafting in the treatment of acne scars.
Materials and methods: Twenty patients were included in this study, 10 received 3 sessions of fractional CO2 laser therapy, and 10 received fat grafting. All patients were then followed up for 3 months, and results were assessed with digital photographs taken by a committee of 3 physicians, by a single-blinded physician, and by reports of patient satisfaction.
Results: In the fractional CO2 laser treatment group, under 20% of patients were graded as having excellent scar improvement, 0 as having marked scar improvement, under 10% as having mild scar improvement, and almost 70% as having moderate scar improvement. In the fat-grafting group, the scar and overall improvement were graded as 30% excellent, 30% marked, 20% moderate, and 20% mild.
Conclusion: Fat grafting proved to be more effective in the treatment of acne scars than ablative fractional CO2 laser treatment. There were many points in its favor, the most significant being the clinical improvement in scars and texture. This supports the stem cell theory of adipose tissue in regenerative medicine.

Objective: The objective of this study was to evaluate the safety and efficacy of photopneumatic technology for the treatment of mild to moderate acne vulgaris.
Methods: Eleven subjects (7 women) aged 15 to 54 years with skin types 1 to 4 presented with mild to moderate facial acne (defined as 15 or more facial inflammatory or noninflammatory lesions) were recruited to the study. All subjects underwent 4 photopneumatic treatments at 3-week intervals with follow-up visits at 1 and 3 months.
Results: Inflammatory lesion counts continued to decrease for at least 3 months after the final treatment. At 3 months, reductions in lesion counts were significant for both inflammatory (P=.0137) and noninflammatory (P=.0383) lesions. Mean scores between visits consistently dropped sharply from their immediate posttreatment values for pain, erythema, and edema. Nine subjects (82%) were moderately satisfied to very satisfied with treatment.
Conclusion: Results suggest that the photopneumatic device is a safe and effective modality for the treatment of mild to moderate inflammatory and comedonal acne vulgaris.
Combined Fractional Ablative and Nonablative Laser Resurfacing Treatment:A Split-Face Comparative Study
Joel L. Cohen MDa and E. Victor Ross MDb| |
Objective: The purpose of this study was to compare a combined fractional ablative and nonablative laser procedure to ablative-only procedures for facial rejuvenation. Methods: A total of 8 subjects in 2 study groups received a single, split-face, facial rejuvenation procedure in this study. In group A, we compared a combined procedure using a fractional nonablative 1,440-nm neodymium-doped yttrium aluminum garnet (YAG) laser and a fractional ablative 2,940-nm erbium (Er)-doped YAG laser on one side of the face, and a combined confluent/fractional ablative Er:YAG laser on the other. In group B, we compared the same 1,440/2,940 treatment as group A on one side of the face, and a fractional ablative CO2 laser on the other. Subjects were followed for 3 months to assess side effects and improvement in Fitzpatrick Wrinkle Score and pigmentation.
Results: Improvement in wrinkles and pigment were seen with all techniques in both groups, and results were equivalent. Areas treated with combined fractional nonablative and ablative technique demonstrated fewer immediate side effects.
Conclusion: Facial rejuvenation using a combination treatment of fractional ablative 2,940 and nonablative 1,440 lasers provides improvement in wrinkles and pigment similar to conservative purely ablative approaches. These purely ablative approaches include the Er:YAG laser used in a sequential confluent fractional manner, or fractional CO2 laser alone. Reduced side effects make the combined procedure an attractive option for facial rejuvenation.

Kee Lee Tan MD, Caroline Kurniawati RN,Michael H. Gold MD| |
Methods: Seven subjects with photodamaged skin received a single facial treatment using a fractional CO2 laser. Anesthesia was limited to a lidocaine and prilocaine cream for 1 hour before the single-pass treatment. Subjects were evaluated for improvement and PIH on alternate days for 14 days, and at 1 month, 3 months, and 6 months posttreatment.
Results: All subjects achieved improvement in their specifi c skin conditions and in skin texture. Postinfl ammatory hyperpigmentation was not observed in any subject. Four subjects experienced no pain during treatment, while 3 reported mild pain. Recovery was associated with minimal pain and itching.
Conclusion: In dark-skinned subjects, fractional CO2 laser treatment and topical anesthesia subjectively improves common skin conditions without PIH.

Photodynamic therapy (PDT) has been considered a safe and efficacious treatment for actinic keratoses (AKs) of the scalp and face. The procedure involves exposing a patient to a blue light source 1-4 hours after application of photosensitizing aminolevulinic acid (ALA) at a dose of 10 J/cm2 for up to 1000 seconds.1,2 We suggest that amount of exposure time and area of exposure should be stratified according to baseline photodamage .

Multi-Center Clinical Study and Review of Fractional Ablative CO2 Laser Resurfacing for the Treatment of Rhytides, Photoaging, Scars and Striae
Macrene Alexiades-Armenakas MD PhD FAAD,a Deborah Sarnoff MD, Robert Gotkin MD, Neil Sadick MD| |
Laser skin resurfacing has shifted over the past two decades from standard ablative resurfacing to non-ablative resurfacing and most recently, to fractional laser resurfacing. In this most recent category, fractional non-ablative lasers were first introduced followed by fractional ablative lasers, which offer an improved balance between safety and efficacy. In the current article, a review of fractional ablative resurfacing is presented alongside the results from a multi-center clinical study employing the fractional carbon dioxide (CO2) laser (SmartXide DOT, DEKA) for the treatment of rhytides, photoaging, scars and striae distensae.

Enhanced Full-Face Skin Rejuvenation Using Synchronous Intense Pulsed Optical and Conducted Bipolar Radiofrequency Energy (ELOS): Introducing Selective Radiophotothermolysis
Neil S. Sadick MD FACP FAACS, Macrene Alexiades-Armenakas MD PhD, Patrick Bitter Jr. MD, George Hruza MD, R. Stephen Mulholland MD| |
Objective: The authors report their experience using an ELOS system (Aurora SR, Syneron, Yokneam, Israel) on 108 consecutive patients treated with a series of full-face procedures.
Methods: Patients received 5 full-face treatments every 3 weeks. Each treatment consisted of 1 to 8 full-face and segmental passes. The number of passes, specific wavelength of pulsed optical energy, and RF energy were determined by the patient’s skin type, dyschromia, wrinkle pathology, and presence of a tan. A total of 540 treatments were performed on 108 subjects. All patients had pre- and post-procedural photographs. Results were assessed by double-blinded physician photographic evaluation and patient satisfaction scales.
Results: Overall skin improvement was rated at 75.3%. Overall average wrinkle improvement was 41.2%, with an average Class 1 wrinkle improvement of 64.7%, Class 2 wrinkle improvement of 38.6%, and Class 3 wrinkle improvement of 20.4%. Improvement in skin laxity was rated at 62.9%. Skin texture was reported to improve 74.1%. Improvement in the appearance of pore size was rated at 65.1%. Average improvement in erythema and telangiectasia was 68.4%. Average improvement in hyperpigmentation and dyschromia was 79.3%. Overall patient satisfaction was 92%. The overall minor complication rate, including blistering, crusting, and stripping was 8.3%, and the major complication rate was less than 1%. One small, depressed nasal scar was observed in one patient.
Conclusions: This study demonstrates the safety and efficacy of a new technology using combined optical and conducted bipolar RF energies for noninvasive skin rejuvenation. The results show improvement in wrinkle reduction and amelioration of erythema, telangiectasia, and hyperpigmentation comparable to that reported for other intense pulsed light technologies.

OBJECTIVE: Determine the level of improvement of post-dermatological surgery scars.
METHODS: Thirty patients attending for excision lesion were recruited. They were randomized to 1 of 2 groups. Group 1 scar was randomly divided into 2 parts, one half received PDL 595 nm on 3 occasions; the first after suture removal, 15 and 45 days. Group 2 in one half laser application was simulated while the other was left untreated. The Vancouver scar scale (VSS) was used by an external evaluator to assess the scars. Two skin biopsies were also obtained one before and one after laser treatment.
RESULTS: The VSS at 45 days decreased in a significant way in the treatment group from 4 to 1 (P = .005). In the control group decreased from 2 to 1.3 (P = .056). No significant difference was found between the presence of inflammatory infiltrate of patients in the placebo group.
CONCLUSION: This study confirmed the usefulness of pulsed dye laser for improving the appearance of scars.

MATERIALS AND METHODS: Under an IRB approved study, eleven subjects with facial photodamage (1 male and 10 female) were enrolled and completed the study. The fractional 1940 nm laser was comprised of a thulium rod pumped by a pulsed alexandrite laser. The fractional patterns were generated by four separate handpieces (two dot (0.48mm and 0.76mm dot-to-dot distance or pitch) and two grid geometries) whereby a larger beam was broken up into smaller microbeams by a microlens system or reflective square grids. The low -pitch circular dot array handpiece, which is used most frequently, has a macro-spot size of 12 mm and a total applied energy of approximately 2-5 J (~ 4-10 mJ per beamlet). Contact skin cooling (5-20degC) was provided via a sapphire window at the distal end of handpiece. Pulses from the dot handpieces were applied with 20% overlap. The microspot size for the dot handpieces was ~ 0.2-0.3 mm. The two grid pattern handpieces included 0.4 mm wide lines with 45% and 0.7 mm wide lines with 65% coverage. Each subject received 3 full-face treatments 4-6 weeks apart. Anesthesia was achieved by 5% lidocaine cream and a cold air chiller. Typical treatments were carried out with two passes. Outcome assessments included changes in pigment, rhytides, laxity, elastosis, and texture, using a diffuse pigmentation scale and the Alexiades-Armenakas Comprehensive Grading Scale of Rhytides, Laxity, and Photodamage. Photographs of each patient from prior to treatment, and 3 months after treatment were analyzed by 3 blinded physician raters. A paired t-test was applied for each category comparing the pre treatment and 3-month post treatment results.
RESULTS: Three months after the final treatment, (a) mean pigment improvement was 21.1%, (b) rhytides were reduced by 14.3%, (c) laxity was reduced by 8.9%, elastosis was reduced by 22.3%, and (e) texture scores were unchanged. Reductions in pigmentation, rhytides, and elastosis were statistically significant (P ≤ 0.05). Clinical downtime was 3-5 days. Pain was variable (mean of 2.8/10) and side effects included two cases of mild focal vesiculation. No long-term side effects were noted. Histological analysis showed focal damage that extended about 200 μm deep to the surface.
CONCLUSION: The 1940nm thulium laser is safe, well tolerated, and results in reduced downtime compared to traditional resurfacing. The study demonstrated that the 1940 nm thulium laser could achieve injury patterns capable of skin rejuvenation.

and Roy G. Geronemus MDa,b
DESIGN: Prospective non-randomized trial.
SETTING: Single center, private practice with a dedicated research department.
PARTICIPANTS: Subjects with clinically diagnosed facial photodamage, melasma, or post inflammatory hyperpigmentation
INTERVENTIONS: Subjects received four to six treatments at 14-day intervals (+/- 3days) with a low energy low density non-ablative fractional 1,927-nm laser (Solta Hayward, CA) with an energy level of 5 mJ, and density coverage of either 5%, 7.5%, or 10%, with a total of up to 8 passes.
MAIN OUTCOME AND MEASURES: Blinded assessment of clinical photos for overall improvement at one and three months post final treatment. Investigator improvement scores, and subject pain and satisfaction scores for overall improvement were recorded as well.
RESULTS: We enrolled 23 subjects, average age 45.0 years (range, 25-64 years), 22 with Fitzpatrick Skin Types I-IV and 1 with Type VI, with facial photodamage, melasma, or post inflammatory hyperpigmentation. Approximately 55% of subjects reported marked to very significant improvement at one and three months post final treatment. Blinded assessment of photography of 20 subjects revealed an average of moderate improvement at one-month follow up and mild to moderate improvement at three months. Average subject pain score was 3.4/10 during treatment.
CONCLUSIONS AND RELEVANCE: Favorable outcomes were demonstrated using the low energy low density, non-ablative fractional 1,927-nm laser in facial resurfacing for photodamage, melasma, and post inflammatory hyperpigmentation. Results were maintained at the 3-month follow up, as demonstrated by investigator and subject assessments, as well as blinded evaluations by three independent dermatologists utilizing photographs obtained from a standardized facial imaging device.

Background: Management of hemangiomas may be a challenge. Different laser systems have been reported to be of significant help for such cases with variable results.
Patients and Methods: In this study, the authors present a unique sequential laser system, which delivers pulsed dye laser (PDL) 595 nm followed by Nd:YAG 1064 nm, which they have found to be superior and more effective than other reported techniques. Twenty-five cases of infantile hemangiomas in the skin and mucous membrane in the head and neck region were selected to be enrolled in this study. Assessment for progress was achieved clinically.
Results: The authors achieved excellent results in eighteen patients (72%) out of the 25 treated patients, with no recurrence after sixmonth follow-up. Laser application from skin and mucous membrane sides (sandwich technique) decreased number of sessions.
Conclusion: The sequential application of 595 nm PDL followed by 1064 nm Nd:YAG laser can be considered a superior method for management of infantile hemangiomas, especially in the head and neck region, due to its excellent cosmetic results with fewer treatment sessions.

Effectiveness of a Nutraceutical During Non-Ablative 1927 nm Fractional Laser on Patients With Facial Hyperpigmentation and Photoaging
Joely Kaufman-Janette MD, Alex Cazzaniga BS MBA, Annelyse Ballin MD and Rachel Swanson-Garcell MSN ARNP| |
Background: Fractional lasers have been proven to treat hyperpigmentation and photoaging. Little research has been done on the effects of supplements on healing post-laser resurfacing. A nutraceutical could offer the benefit of faster healing of the skin and fewer side effects.
Objective: Evaluate the effectiveness of a nutraceutical associated with fractional 1927 nm laser in healing time and effectiveness on hyperpigmentation and photoaging.
Methods & Materials: A prospective, randomized, evaluator-blinded, pilot study included Fitzpatrick skin types I-III patients with hyperpigmentation and photoaging randomly assigned to two groups. Group 1 was laser treatment and Group 2 was laser treatment and nutraceutical. Results were compared with objective biometric TEWL (transepidermal water loss), mexameter, corneometer, and cutometer parameters. A blinded physician-evaluator and the subjects completed questionnaires to evaluate skin improvements.
Results: Twenty women were included. Eight in Group 1 and 10 in Group 2 completed the study. Group 2 presented a faster recovery of the skin barrier function post procedure. Three months after the procedure, Group 2 presented with significantly improved skin glossiness, hydration, and melanin rebound levels. Group 2 presented more overall aesthetic improvement determined by the patient and the blinded physician-evaluator.
Conclusion: The nutraceutical improved the results of the laser treatment.

A series of 32 consecutive patients underwent a single laser resurfacing procedure with the a new microablative CO 2 laser. All patients were followed for a minimum of 6 months and were asked to complete patient satisfaction questionnaires; a 6 month post- operative photographic evaluation by an independent physician, not involved in the treatment, was also performed. Both sets of data were graded and reported on a quartile scale. Results demonstrated greater than 50% improvement in almost all patients with those undergoing treatment for wrinkles, epidermal pigment or solar elastosis deriving the greatest change for the better (>75%).

STUDY DESIGN/MATERIALS AND METHODS: Porcine skin and fat tissue were prepared and separated to form a 2mm skin layer above a 1 cm thick fat layer. A 50μm thermocouple was placed between the layers and centered beneath a 23 x 38 mm treatment window of an 805 nm diode laser device (Vectus, Cynosure, Westford, MA). Apertures provided various incident beam spot sizes and the temperature rise of the thermocouple was measured for a fixed fluence.
RESULTS: The 2mm deep target's temperature rise versus treatment area showed two regimes with different positive slopes. The first regime up to approximately 1 cm2 area has a greater temperature rise versus area than that for the regime greater than 1 cm2. The slope in the second regime is nonetheless appreciable and provides a fluence reduction factor for skin safety. The same temperature rise in a target at 2 mm depth (typical hair bulb depth in some areas) is realized by increasing the area from 1 to 4 cm2 while reducing the fluence by half.
CONCLUSIONS: The role of spot size and in situ beam divergence is an important consideration to determine optimum fluence settings that increase skin safety when treating deeper targets.

BACKGROUND: Fractional photothermolysis (FP) is a popular treatment option for photodamaged skin and addresses shortcomings of ablative skin resurfacing and nonablative dermal remodeling. Previous studies have demonstrated that FP using the 1550nm wavelength has led to improvement of ultrastructural changes and clinical effects associated with photodamaged skin in the deeper dermal structures, while treatment with the 1927nm wavelength has shown clinical effects in the superficial dermis. Both wavelengths produce precise microscopic treatment zones (MTZs) in the skin. The two wavelengths used in combination may optimize the delivery of fractional nonablative resurfacing intended for dermal and epidermal coagulation of photodamage skin.
OBJECTIVES: To evaluate the safety and efficacy of a 1550/1927 Laser System (Fraxel Dual, Solta), using both 1550nm and 1927nm wavelengths in combination for treatment of facial and non-facial photodamage.
METHODS: Prospective, multi-center, post-market study in subjects with clinically identifiable photodamage (N=35) (Fitzpatrick skin types I-IV). Both 1550nm and 1927nm wavelengths were used at each treatment visit. Investigator assessment of the affected area(s) occurred at one week, one month and 3 months after a series of up to four treatments. Severity of adverse events (AEs) were assessed using a 4-point scale (where 0=none and 3=marked). Assessments included erythema, edema, hyperkeratosis, hyper- and hypo-pigmentation, scarring, itchiness, dryness, and flaking. Severity of photoaging, fine and coarse wrinkling, mottled hyperpigmentation, sallowness, and tactile roughness at baseline was assessed using the same scale. Investigators and subjects assessed overall appearance of photodamage and pigmentation based on a 5-point quartile improvement scale at all follow-up visits (where 0=no improvement and 4=very significant improvement [76%-100%]).
RESULTS: There was a positive treatment effect at all study visits, with moderate improvement (average reduction in severity of 21%-43%) observed 3-months after final treatment. Greatest reduction in severity of other benefit areas was at the 3-month follow-up visit, with a 21% and 30% decrease in severity in fine wrinkling and tactile roughness. No AEs or serious AEs were reported. Pain sensation during treatment was tolerable. Anticipated moderate erythema (mean score 1.6±0.5) and mild edema (mean score 0.8±0.7) were transient and resolved within 7-10 days. Anticipated and transient mild dryness (52% of subjects) and flaking (30%) were reported at the 1-week follow-up. There were no incidences of hyperkeratosis, scarring, or itchiness.
CONCLUSION: Treatments using both wavelengths associated with the combined 1550/1927 Laser System were well tolerated with limited, transient anticipated side effects and no serious AEs. Clinical efficacy in the appearance of photodamage and pigmentation was greatest following a series of up to 3 treatments.

Biophysical Evaluation of Fractional Laser Skin Resurfacing With an Er:YSGG Laser Device in Japanese Skin
Background: Ablative fractional laser skin resurfacing (FLSR) has recently been used for the amelioration of acne scars, and previous
studies have shown clinical effectiveness. Despite its extensive use, few studies have focused on the associated changes in biophysical
properties of the epidermis. Herein, we evaluate transepidermal water loss, sebum levels, skin hydration, and skin elasticity, following
FLSR treatments with an Er:YSGG laser device (Pearl FractionalTM , Cutera Inc., Brisbane, CA), employing non-invasive measurements.
Methods: Five Japanese patients with facial acne scars underwent one FLSR session. Some acne scars appeared to become less obvious as a consequence of the treatment. All patients were aware of a feeling of skin tightness in treated areas.
Results: Objective measurements on the lower lateral angle of the eye and on the inner cheeks were evaluated at baseline and at 3 days, 1 week, and 4 weeks after FLSR. Transepidermal water loss showed a significant two-fold (100%) increase at day 3, but had returned to almost the baseline level at week 4 in both areas. Sebum secretion showed a 50% increase at day 3, but had returned to the baseline level after day 7. Skin hydration showed a significant decrease at day 3, but had returned to the baseline level by day 7, and showed significant improvement at the end of the study. Skin elasticity (R2) was still at baseline on day 3, but showed some improvement—an increase of at least 30%—at the end of the study.
Conclusions: Based on our findings, we believe that FLSR should be performed no more than once a month to allow sufficient time for the damaged skin to recover its barrier function in most areas of the face.

A Prospective Study of the Improvement in Periorbital Wrinkles and EyebrowElevation With a Novel Fractional CO2 Laser—The Fractional Eyelift
Dvora Ancona MD and Bruce E. Katz MD| |
Materials and Methods: One hundred subjects with periocular wrinkles, tissue laxity, photoaged skin and moderate dermatochalasis of the face were prospectively treated one to four times in the periorbital area with a fractional CO2 laser device equipped with a scanning handpiece. Improvements in eyelid wrinkles, crow’s feet and skin laxity were evaluated photographically by two blinded, independent observers. Eyebrow elevation was measured by the investigators. Subjects also scored satisfaction and tolerability.
Results: Approximately half of subjects achieved or maintained 26–50% improvement at 12 months. Nearly 40% of subjects maintained 1–2 mm elevation of the brow at six and 12 months after treatment. Subject satisfaction was high and the procedure was well tolerated. Mild-to-moderate erythema and edema persisted for up to three to four days.
Conclusion: Treatment with a fractional CO2 laser device improves periorbital rhytids, tightens skin and elevates the eyebrow with minimal adverse effects.

Home-Based Wrinkle Reduction Using a Novel Handheld Multisource Phase-Controlled Radiofrequency Device
Neil S. Sadick MD,1 Yoram Harth MD,2,3 Andrew S. Dorizas MD,6 Hanna Levy PhD,4 and Avner Shemer MD5| |
PATIENTS AND METHODS: A total of 69 participants (age 54.3 years ± 8.09; age range 37-72 years) were enrolled in the study after meeting all inclusion/exclusion criteria (100%) and providing informed consent. Participants were provided with the tested device together with a user manual and treatment diary, to perform independent treatments at home for 4 weeks. The tested device, (Newa™, EndyMed Medical, Cesarea, Israel) emits 12 W of 1Mhz, RF energy through six electrodes arranged in a linear fashion. Independent control of RF polarity through each one of the 6 electrodes allows significant reduction of energy flow through the epidermis with increased dermal penetration. Participants were instructed to perform at least 5 treatments a week, for one month. Four follow-up visits were scheduled (once a week) during the period of independent treatments at home, following 4 weeks of home treatments, 1 month follow-up visit (1 month after treatment end) and at 3 months follow-up (3 months following treatment end).
Analysis of pre-and post treatment images was conducted by three uninvolved physicians experienced with the Fitzpatrick Wrinkle and Elastosis Scale. Fitzpatrick Wrinkle and Elastosis score of each time point (4 weeks following home use treatments; 1 month follow-up, 3 months follow-up) was compared to baseline.
Participants were asked a series of questions designed to explore usability concerns and level of satisfaction regarding the device use and subjective efficacy.
RESULTS: Altogether, 62 subjects completed the study course and follow-up visits. No unexpected adverse effects were detected or reported throughout the independent treatment. All study participants did not experience any difficulties while operating the tested device for independent wrinkle reduction treatments. Photographic analysis of pre- and post-one month of independent home use treatments, and one and three months follow-up after end of treatment course, was conducted by three uninvolved board certified dermatologists. Analysis of results revealed improvement (downgrade of at least 1 score according to the Fitzpatrick scale) in 91.93%, 96.77%, and 98.39% of study subjects (according to the first, second, and third reviewer, respectively). Results were found to be statistically significant. The majority of study participants were very satisfied from the results of the independent treatment using the tested device for wrinkle reduction.

BACKGROUND: Actinic keratoses (AKs) are dysplastic lesions of the epidermis that have the potential to progress to non-melanoma skin cancers (NMSC). Traditional photodynamic therapy (PDT) requires a pre-illumination incubation time, which adds to overall in-office time and has been linked to pain. Our group has found a novel protocol to effectively treat AKs with PDT that eliminates the pre-illumination incubation period and uses 2 back-to-back cycles of 16 minute 40 seconds.
METHODS: The patient was prepped with soapy water and isopropyl alcohol, and thick AKs were descaled with a curette. Next, 5-aminolevulinic acid (ALA) was applied to the treatment areas and the patient was immediately placed under the blue light for 33 minutes and 20 seconds (two cycles of 16m/40s).
RESULTS: During therapy, the patient reported no pain. At one week, treated areas revealed a good reaction. The procedure was repeated at one month to treat residual AKs. At a 4-month follow-up, the patient’s face and scalp showed near clearance of any AKs.
CONCLUSION: During PDT, the photosensitizer aminolevulinic acid (ALA), or in Europe methyl aminolevulinate (MAL), is utilized as a synthetic precursor that preferentially accumulates in dysplastic cells. The precursor then converts to PpIX via the heme pathway and causes apoptosis of the cells when excited, most commonly by either blue-violet (400-430 nm) or red (630-635 nm) light. Shorter incubation times are associated with reduced pain because less PpIX will have accumulated in the treated tissue by the start of the exposure to the light. The doubling of the light exposure time allows comparable levels of the photosensitizing molecule to accumulate and be activated so as to produce an equivalent reaction. The associated reduction in pain along with a more convenient treatment schedule makes this PDT protocol more tolerable and convenient to some patients.

METHODS: Female subjects age 35-65 with Fitzpatrick Skin Type I-IV and mild to moderate amounts of photodamage, fine lines, and wrinkles used Regenica® Replenishing Crème and Regenica® Renew SPF 15 for 3 months. At each visit, photos were taken of subjects while investigators completed skin grading assessments and subjects completed self-assessments. Investigator assessments included evaluation of tactile roughness, visual texture, wrinkles, blotchiness, skin tone evenness, radiance, and translucence on a 5-point scale. Subjects’ self-assessments included assessment of fine lines and wrinkles, firmness, evenness of skin tone, brightness, resilience, clarity, and radiance. Changes from baseline were evaluated for each parameter and P values for changes from baseline to each study visit for investigator’s assessments and to end-of-study for self-assessments were calculated.
RESULTS: Eighteen of 21 enrolled female subjects completed the study. Three subjects chose to drop from the study. Statistically significant improvements in investigator assessments of tactile roughness, visual texture, wrinkles, blotchiness, skin tone evenness, radiance and translucency compared to baseline were observed at weeks 4, 8, and 12 after initiating treatments. Progressive improvement was seen through the last study visit (visit 5, week 12). Similar statistically significant improvements in subjects’ self-assessments were seen comparing the first post-baseline visit (visit 2, week 2) to subsequent visits. 93.5 % subjects agreed (somewhat or strongly) with all of the positive subject assessment statements at week 12. Importantly, 100 % of subjects indicated at the end of the study that they would recommend the product to a friend and would want to purchase the product. No treatment-related adverse events were recorded during the study.
CONCLUSIONS: Regenica was safe and clinically effective in reducing anti-aging effects in this group of female subjects aged 35-65 years as measured by both investigator assessments and subjects’ self-assessments.

Treatment of Focal Axillary Hyperhidrosis Using a Long-Pulsed Nd:YAG 1064 nm Laser at Hair Reduction Settings
Study Design/Materials and Methods: In a prospective, case-controlled, randomized pilot study, one axilla from six different subjects with axillary hyperhidrosis was treated with monthly laser hair reduction sessions using the 1064 nm Nd:YAG laser at typical settings. The contralateral axilla acted as a control. Subjects were asked to subjectively classify improvement of axillary sweating using a Global Assessment Questionnaire (GAQ) weekly after each treatment. Qualitative evaluation of sweating was also performed using a modified starch iodine test monthly after each treatment. In addition, prior to the first treatment and at one month following the final treatment, a punch biopsy was performed on the treatment axilla to assess for histologic changes to the eccrine gland and surrounding structures.
Results: Statistically significant improvements in subjective ratings of sweating using the GAQ compared to baseline were observed. Objective improvements in sweating with modified starch iodine testing comparing treated versus non-treated axillae were also seen for at least nine months in selected subjects. No significant differences in pre- and post-treatment biopsies were noted on routine histology.
Conclusions: Laser hair reduction using the 1064 nm Nd:YAG at laser hair removal settings provides subjective and objective improvements in patients with focal axillary hyperhidrosis.

A Multicenter, Randomized, Vehicle-Controlled Phase 2 Study of Blue Light Photodynamic Therapy With Aminolevulinic Acid HCl 20% Topical Solution for the Treatment of Actinic Keratoses on the Upper Extremities: The Effect of Occlusion During the Drug Incubation Period
George J. Schmieder DO,a Eugene Y. Huang MD PhD,b and Michael Jarratt MDc| |
Objectives: To determine and compare the safety and ef!cacy of blue light ALA-PDT vs blue light placebo vehicle (VEH) in the treatment of AKs of the upper extremities and to evaluate the effect of occlusion after application of ALA vs VEH.
Methods: ALA or VEH was applied to both dorsal hands/forearms for the 3-hour incubation period before blue light treatment (10 J/ cm2). One extremity of each subject was covered with occlusive dressing during the incubation period. Treatment was repeated at week 8 if any AK lesions remained.
Results: The median AK lesion clearance rate at week 12 was 88.7% for extremities treated with occluded ALA (ALA+OCC), 70.0% for extremities treated with nonoccluded ALA, 16.7% for extremities treated with occluded VEH (VEH+OCC), and 5.6% for extremities treated with nonoccluded VEH (P<.0001). ALA+OCC resulted in a significantly higher clearance rate compared with the nonoccluded extremity at weeks 8 (P=.0006) and 12 (P=.0029). Thirty-four percent (12/35) of extremities treated with ALA+OCC had complete clearance of lesions at week 12 compared with 0% (0/35) of extremities treated with VEH+OCC (P=.0002). The safety pro!le in this study is consistent with previously reported side effects of the therapy.
Conclusion: Blue light ALA-PDT following a 3-hour incubation appears efficacious for AK clearance of the upper extremities. Incubation using an occlusive dressing significantly increases the efficacy of the procedure and also increases the incidence and severity of some acute inflammatory side effects of PDT.

Currently, sunscreens play an important role in maintaining the health of the skin by providing “broad spectrum” protection against the harmful effects of UV radiation. However, this does not protect human skin from 94.2% of solar radiation (comprised of visible and IR lights), and nor does it prevent heat accumulation damage. Thus, none of the commercially-available sunscreens is able to block 100% of UV radiation.
Inspired by the need to provide patients with a more comprehensive solar protection, SkinMedica® has created Total Defense + Repair (TD+R), which combines broad spectrum UV protection with a unique blend of antioxidants (SOL-IR Advanced Antioxidant ComplexTM) that provide protection from IR radiation while promoting skin repair. These antioxidants are the product of scientific research and breakthrough technology, providing the next generation of multifunctional skin care products.

OBJECTIVE: We examined the use of the 300 microsecond 1064 nanometer (nm) Nd:YAG laser for the treatment keloids in patients with skin types ranging from Fitzpatrick I through VI.
METHODS & MATERIALS: A retrospective analysis of treatment efficacy was conducted on 44 patients with keloids. Three separate treatment groups were compared. The groups consisted of: a “control group” in which the whole keloid was only treated with intralesional corticosteroid (triamcinolone 10mg/cc) (16 patients); a “laser only” group in which the patient’s keloid was only treated with the 1064nm Nd:YAG laser at a fluency of 13 to 18 Joules / centimeter2 (J/cm2), a fixed pulse duration of 300 microseconds, 5mm spot size, and a total of 2000 pulses (14 patients); and a “combination group” that received both the aforementioned laser therapy and adjuvant intralesional triamcinolone (14 patients).
RESULTS: Patients in the "combination group" treated with the 300 microsecond 1064nm Nd:YAG laser therapy plus intralesional corticosteroid and the "laser only" group both were observed to have durable clinical reduction in the thickness and erythema of the keloids. These results were shown to be superior to the "control group" whom were only treated with intralesional corticosteroids. Only mild and transient post treatment erythema was noted as an adverse effect.
STATISTICAL ANALYSIS: Data analysis was performed using IBM SPSS Statistics 19.0.0 (Armonk, NY). In order to assess the statistical significance of differences in keloid improvement among the three treatment groups, The Kruskal-Wallis test (non-parametric ANOVA test) was applied. The level of statistical significance was set at P<0.05. A statistically significant difference in keloid improvement was appreciated between treatment groups (P<0.0001).
LIMITATIONS: A small sample size and the retrospective nature of the analysis are limitations to the study.
CONCLUSION: The 300 microsecond 1064nm Nd:YAG laser proved effective in improving the clinical appearance of keloids. We recommended this laser protocol in conjunction with intralesional corticosteroids as a treatment option for patients with keloids, especially in the skin of color population. The 1064nm Nd:YAG laser did not show post inflammatory hyperpigmentation nor hypopigmenatation, which are concerns for skin types IV to VI, and therefore is a suitable option for such patients.

Analysis of Depth of Ablation, Thermal Damage, Wound Healing, and Wound Contraction With Erbium YAG Laser in a Yorkshire Pig Model
Salman M.S. Alsaad MD,a E.Victor Ross MD,b Wiley J.Smith MD,c and Damian P.DeRienzo MDd| |
MATERIALS AND METHODS: The laser delivered an ablative pulse followed by a heating pulse of variable duration using either the full coverage or fractional hand piece. Pulse durations for specific coagulation depths were selected based on existing heat transfer models. The bilateral flanks of a single Yorkshire pig were irradiated. There were 14 treatment groups. 3 sites were treated per group for a total of 42 sites. Two of the 3 sites were for observational assessments and the 3rd site served as a reservoir for biopsies. Biopsy specimens were collected on days 0, 1, 3, 7, 14, and 28. Bleeding, erythema, wound healing, and wound contraction (in the fractional hand piece groups) were assessed.
CONCLUSION: Wound healing is faster for fractional laser skin resurfacing compared with traditional contiguous resurfacing as demonstrated by textural changes and degree of erythema. The laser operator can be confident that the depth of ablation displayed on this system accurately reflects what is occurring in vivo for both confluent and fractional modes. Likewise, the measured degree of coagulation was consistent with panel display settings for the confluent mode. However, the degree of coagulation, as measured by the thickness of residual thermal damage, did not vary significantly between the fractional groups. In other words, the pulse duration of the second (heating) pulse did not impact the degree of coagulation in the fractional mode. There was a 2.3% wound contraction between some groups and a 6.5% wound contraction between other groups. A two way analysis of variance found a statistically significant difference in wound contraction based on ablation depth (P=0.012) but the degree of coagulation did not prove to be statistically significant for wound contraction (P=0.66).

OBJECTIVE: To evaluate the safety and efficacy of a focal approach to fractional CO2 laser treatment for acne scars, coined “Focal Acne Scar Treatment” or “FAST”
PATIENTS and METHODS: This retrospective case series was conducted at Schweiger Dermatology, in New York, NY, with patients treated from November 2011 through May 2012. Overall, six patients (ages 18 to 48) were treated with the fractional CO2 laser resurfacing, using a so called “FAST” technique treating only the acne scars and leaving normal skin untreated. Evaluation was based on physician and patient assessment of improvement at one week and four weeks post-treatment.
RESULTS: All six patients treated with the Focal Acne Scar Treatment technique of fractional CO2 laser resurfacing had significant improvement post treatment ranging from 40% to 70% as estimated by the treating dermatologist and patient at four weeks post treatment. Patient satisfaction was high following FAST method. Temporary post-inflammatory hyperpigmentation was seen in two patients but resolved after a single 1550 nm Erbium Glass fractional laser treatment.
CONCLUSION: The Focal Acne Scar Treatment technique is an effective method of improving the appearance of atrophic acne scars. Higher energy and density levels can be used when utilizing this technique, resulting in improved outcomes when compared with whole face fractional CO2 laser resurfacing. Healing is improved and faster with this technique and no increased incidence of permanent adverse events were found. More studies are needed to further evaluate this new technique.

Methods: Thirty-one subjects with Fitzpatrick skin types V and VI were consented for treatment with the system. Twenty-six subjects completed the 12-week follow-up. Safety was evaluated at each visit and efficacy was evaluated at both follow-up visits.
Results: An average hair clearance of 41.7% from 57 treatment sites was reported at the 6-week follow-up visit and a 35.5% average hair clearance was reported at the 12-week follow-up. Edema was only reported in 2 cases (7.7%) of the study population. Eleven cases of erythema were reported following treatment.
Conclusion: Treatment with the modified LHE system was safe and effective for hair removal in patients with skin types V and VI.

At day 90, ≥ 75% overall improvement was reported in 72% and 19% of patients in the HQ/tret + IPL group and the placebo + IPL group, respectively. HQ/tret + IPL was also associated with significantly lower mean hyperpigmentation scores at days 30, 60 and 90 (P≤0.05), and significantly lower mean laxity scores at day 90 (P≤0.05) compared with placebo + IPL. Adjunctive use of the HQ/tret system enhances the improvements in facial skin achieved with IPL treatment.

Objective: To determine the safety and efficacy of fractional photothermolysis treatment on striae alba and striae rubra.
Methods: Twenty female patients with striae rubra or striae alba on their abdomen, thighs, or buttocks were enrolled in the study. Lesions were randomized to receive treatment, with site-matched normal control areas. Patients received a total of 6 treatments using a 1550-nm, erbium-doped fiber laser with 2 to 3 weeks of elapsed time between treatments. Clinical response to treatment was assessed at each visit, and at 1-month, 2-month, and 3-month follow-up intervals by the patient and investigator. A comparison evaluation of 8 patients examining photographs of striae at baseline and at the 3-month follow-up evaluation which was assessed by 4 independent dermatologists using the quartile grading scale.
Results: The independent evaluators’ assessments of improvement from photographs of 8 randomly selected patients showed an overall improvement of 26% to 50% in 63% (5/8) of patients. A less than 25% improvement in dyschromia was noted in 50% (4/8) of patients. An improvement in texture of 26% to 50% was observed in 50% (4/8) of patients. The clinical responses were indepen- dent of age, gender, and skin phototype. The treatments were tolerated well by all patients with a majority of patients experiencing transient posttreatment erythema and edema.
Conclusion: Fractional photothermolysis can be effectively and safely used in the treatment of striae rubra and striae alba.
Effect of Retinoid Pretreatment on Outcomes of Patients Treated by Photodynamic Therapy for Actinic Keratosis of the Hand and Forearm
Barry I. Galitzer MD| |
Background/Objective: Photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) has been shown to be useful in both spot and field treatments of actinic keratoses (AK). This study evaluates the safety and efficacy of pretreatment of AK lesions on the dorsal hands and forearms with tazarotene gel (0.1%) twice a day for one week before broad-area ALA PDT.
Methods: Ten subjects aged 75.4 ± 11.6 years (mean ± SD) with at least four AK lesions on their dorsal forearm or hand were randomized so that one dorsal hand or forearm was pretreated with tazarotene gel (0.1%) twice daily for one week before ALA PDT with blue light. The other hand or forearm (control) was not pretreated. After seven days, ALA was applied to both sides and incubated 60 minutes before irradiation with blue light. ALA was applied first only to the AK lesions and then to the entire treatment area (defined as the extensor surface of the hand or forearm between the elbow and the base of the fingers) before 60-minute incubation. The ALA area on the control side was occluded during the 60-minute incubation. Efficacy and adverse effects were evaluated within 48 hours and eight weeks later.
Results: For both the pretreated and control group, lesion counts of the target areas decreased significantly from baseline to eight weeks after ALA PDT. Reduction percentages of the target area, however, did not differ significantly between the two groups. When reduction percentages of the entire treatment area for both groups were compared the difference between the two groups was of borderline significance (P=0.0547). When the entire treatment area was analyzed, lesion counts of the tazarotene group differed significantly from baseline at eight weeks (P=0.0002), but this was not the case with the control group (P=0.0365). Adverse events were limited to those expected after ALA PDT. Erythema was significantly more severe (P=0.0029) in the pretreated arm five minutes after ALA PDT.
Conclusion: Pretreatment of AK lesions on the dorsal hand and forearm with tazarotene gel (0.1%) may enhance the therapeutic effect of ALA PDT without serious side effects.

Efficacy of Low-Fluence Nd:YAG 1064 nm Laser for the Treatment of Post-Inflammatory Hyperpigmentation in the Axillary Area
Sahar Ghannam MD PhD,a,b Fatemah K. Al Otabi,c Konstantin Frank,d and Sebastian Cotofana MD PhDe| |
OBJECTIVE: Post-inflammatory hyperpigmentation results in aesthetically unpleasant discoloration of the skin in the affected area. The efficacy of low-fluence Q-switched 1064-nm Nd:YAG laser has so far not been evaluated for the treatment of the axilla. This observational study was designed to evaluate whether the application of the laser treatment can satisfactorily reduce axillary hyperpigmentation. MATERIAL AND METHODS: 17 females (mean age, 34.27 ± 9.24; range, 19–48) were treated in a single center between 2014 and 2016 for post-inflammatory hyperpigmentation of the axillary area. One treatment session was done every 2 weeks. Pairwise pre- / post-treatment assessment was graded by the practitioner, the patient, and an independent non-medical observer for consistency using a standardized grading scale. RESULTS: Post-treatment evaluation revealed an improvement score of 4 ± 0.44; range, 4–5 (good improvement) with a variance of 0.19 after the treatment. The scoring of the practitioner rs= 0.31 correlated higher with the patient-related outcome than with the scoring of the independent non-medical observer rs= 0.17. The minimum number of sessions needed for an excellent patient-evaluated improvement was 3, but an increased number of sessions was not significantly correlated with the outcome. The results of the treatment lasted for at least 6 months after the last session. CONCLUSION: A low-fluence Q-switched 1064-nm Nd:YAG laser provided safe and effective treatment for post-inflammatory hyperpigmentation in the axillary area, with good-to-excellent improvement after a minimum of 3 sessions.

Background: Body contouring with liposuction including laser liposuction is one of the most commonly performed cosmetic procedures. Laser lipolysis is generally well tolerated with high patient satisfaction rates. Laser lipoplasty has been postulated to offer the unique advantage of skin tightening following removal of subcutaneous fat. The search continues for an optimal wavelength that would allow for: (1) efficient targeting of adipocytes while targeting dermal collagen and collagen bound water to allow for dermal remodeling and (2) targeting hemoglobin and vessel wall collagen to decrease intra-operative bleeding and consequent post-operative bruising.
Objective: The main objective of this study was to determine the effects of 1064 nm and 1320 nm Nd:YAG lipolysis on fresh ex vivo human abdominal fat pads.
Materials & Methods: Ipsilateral 1064 nm Nd:YAG lipolysis and contralateral 1320 nm Nd:YAG lipolysis were performed on ex vivo human abdominal fat pads from comparable topographic areas of the body of the same patient. Biopsy specimens were assessed for alterations of the epidermis, papillary and reticular dermis and subcutaneous fat.
Conclusion: Our histological analysis demonstrated a wavelength dependent differential dermal response. Increasing fluence led to progressively more extensive dermal coagulation with associated epidermal thermal injury with 1320 nm Nd:YAG leading to more extensive collagen coagulation as compared to 1064 nm Nd:YAG.

The seborrheic keratosis (SK), which is ubiquitous throughout all populations, is a benign tumor of the skin. SKs are among the top 20 dermatologic conditions treated by dermatologists. They have been reported to occur in individuals of all ages including children as young as age 15 years. Familial cases of SKs have been described with an autosomal dominant inheritance pattern. Mutations of the fibroblast growth factor receptor 3 gene (FGFR3) and the gene encoding for phosphoinositide 3-kinase (PIK3CA) have been demonstrated in SKs. In addition to a genetic predisposition, independent risk factors include advancing age and ultraviolet light exposure. It has been proposed that these two risk factors may also contribute to the development of SKs caused by the genetic mutation in FGFR3 gene, which is involved in regulating cell growth, differentiation, migration, and wound healing. The classic description of a SK is a papule or plaque with a soft, friable, hyperkeratotic surface, or a macule with a fine granular appearance. Variants include the stucco seborrheic keratosis and dermatosis papulosa nigra (DPN). Although diagnosed clinically, mimickers of SKs are well known with melanoma being the most concerning. Treatment of SKs is primarily procedural with new treatments in development.

Based on the cost analysis model, the least expensive treatment option for non-genital warts were carbon dioxide laser therapy ($157) and Candida antigen injections ($190). The other treatment modalities examined ranged from $495 (bleomycin) to $1227 (interferon alpha). Although treatment with the carbon dioxide laser therapy is the least expensive, pain and post-procedure complications limit the use of this modality.

Histologic and Clinical Response to Varying Density Settings With a Fractionally Scanned Carbon Dioxide Laser
Raminder Saluja MD, Jane Khoury MD, Susan P. Detwiler MD, Mitchel P. Goldman MD| |
Objective: An evaluation of the histological and clinical response to varying density settings (-10%, 0, and 10% overlap) with a frac- tionally scanned CO2 laser.
Study design: Clinical and histological study evaluating abdominoplasty excised tissue for depth of penetration and width of tissue ablated with varying density and energy settings utilizing a scanned microsecond pulsed CO2 laser. These parameters were corre- lated clinically with patients treated with similar density settings.
Participants: Fifteen patients were enrolled with 5 patients in each group: group 1 (density 1 settings), group 2 (density 2 settings) and group 3 (density 3 settings).
Main outcome: Histological differences of width and depth of tissue ablated with varying density settings and correlation with pho- todamage improvement clinically.
Methods: Six samples of excised abdominoplasty tissue were treated with increased energy and density settings and were evalu- ated histologically. Clinically, 15 patients with photodamage to the face were randomized to receive a fractional CO2 laser treatment with density levels ranging from 1 to 3.
Results: Microarrays of tissue injury were visualized with multiple areas of superﬁ cial to full-thickness epidermal thermal damage. As energy increased (90W to 100W), the width of basophilic coagulation of the subepidermal collagen increased. Increased density paralleled increased depth of penetration of subepidermal coagulation. Patient assessment of discomfort, erythema, edema, and satisfaction with the procedure was proportional to increasing densities.
Conclusion: A fractional CO2 laser produces photorejuvenation, erythema, edema and discomfort in proportion with the depth and extent of epidermal and subepidermal thermal damage.

OBJECTIVE: To demonstrate that a combination technique called ACELIFT – an acronym for the Augmentation of Collagen and Elastin using Lasers, Injectable neurotoxins, Fillers, and Topicals – in selected patients, is a viable, safe, and effective alternative to a facelift.
METHODS: Ten healthy women, ages 50 to 62 (mean age = 58), with cervical and facial stigmata of aging were enrolled in a prospective study conducted in the authors’ private practice. Patients underwent a two-step procedure; the first step was laser lipolysis of the submental and anterior cervical areas with a pulsed 1440nm Nd:YAG laser with a side-firing fiber (PrecisionTx, Cynosure, Westford, MA). Three months later, the patients were treated in a single session that combined injectable neurotoxin, fillers, and fractional (Fx) CO2 laser resurfacing delivered in a novel “hammock” distribution. After two weeks, following complete re-epithelialization, the patients were started on a topical regimen that included daily use of sunscreen and antioxidants and nightly use of retinoids and peptides. This regimen was continued for a period of six months when all patients returned for final evaluation.
RESULTS: Nine months following the initiation of treatment, all patients were evaluated by the following: Global Aesthetic Improvement Scale, cervicomental angle scale, physician, and subject evaluation. Clinical improvement was evident, and often marked, for all subjects. Both physician and subject satisfaction scores were high, indicating overall satisfaction with the procedure and the outcomes. Side-effects were mild and transient; there were no incidents of adverse scarring, thermal injuries, permanent nerve injury, or dyschromia, hematomas, seromas, or infection. Subjects were likely to recommend the procedure to a friend.
CONCLUSIONS: In properly selected patients, the ACELIFT proved to be a safe and effective, minimally invasive alternative to a facelift. There was little downtime and high patient satisfaction.

INTRODUCTION: Hair loss is a common complaint seen in dermatology clinics. From frustration and attempts at self-help, patients with hair loss may present to the dermatologist with false beliefs, or myths, about the causes of their condition and what treatments are effective.
METHODS: We identified 12 common myths about hair loss, categorized as myths about minoxidil treatment, vitamin and mineral supplements, natural topical treatments, and hair care practices. We performed a PubMed search to find evidence to support or refute each myth.
RESULTS: We found that there is little evidence to support many of these common hair loss myths. In some cases, randomized controlled trials have investigated the effects of particular therapies and point to the effectiveness of certain hair loss treatments.
DISCUSSION: In many cases, there have not been sufficient randomized controlled trials to evaluate the effect of different therapies and hair care practices on hair loss. It is best to guide patients toward treatments with a long track record of efficacy and away from those where little is known scientifically.

METHODS: A patient with profoundly severe perioral photodamage etched-in lines underwent full-field ablative perioral resurfacing with an erbium laser (Contour TRL, Sciton Inc., Palo Alto, CA) that allows separate control of ablation and coagulation. The pre-procedure consultations included evaluation of the severity of etched-in lines, and discussion of patient goals, expectations, and appropriate treatment options, as well as a review of patient photos and post-treatment care required. The author generally avoids full-field erbium ablation in patients with Fitzpatrick type IV and above. For each of 2 treatment sessions (separated by approximately 4 months), the patient received (12 cc plain 2% lidodaine) sulcus blocks before undergoing 4 passes with the erbium laser at 150 μ ablation, no coagulation, and then some very focal 30 μ ablation to areas of residual lines still visualized through the pinpoint bleeding. Similarly, full-field ablative resurfacing can be very reliable for significant wrinkles and creping in the lower eyelid skin – where often a single treatment of 80 μ ablation, 50 μ coagulation can lead to a nice improvement.
RESULTS: Standardized digital imaging revealed significant improvement in deeply etched rhytides without significant adverse events.
CONCLUSION: For appropriately selected patients requiring perioral (or periorbital) rejuvenation, full-field ablative erbium resurfacing is safe, efficacious and merits consideration.

Monopolar Radiofrequency Facial Tightening: A Retrospective Analysis of Efficacy and Safety in Over 600 Treatments
Robert A. Weiss MD, Margaret A. Weiss MD, Girish Munavalli MD MHS, Karen L. Beasley MD| |
Study Design: Charts and clinical images of over 600 consecutive patient treatments between May 2002 and June 2006 using a monopolar radiofrequency device (Thermacool®, Thermage, Haywood, CA) for skin tightening at the Maryland Laser, Skin and Vein Institute were retrospectively reviewed. The primary presentation for treatment was skin laxity of the lower face. Treatment was delivered with a 1-cm2 standard tip at fluences of 81 to 124 J/cm2 (level of 12.5 to 15), a 1-cm2 “fast” tip at fluences of 62 to 109 J/cm2 (level of 72.0 to 76.0), a 1.5-cm2 “big fast” tip at fluences of 75 to 130 J/cm2 (level of 61.5 to 65), and a 3-cm2 “bigger” tip at equivalent fluences as each became available. As treatment algorithms evolved over 4 years, the algorithm of multiple passes at lower fluence associated with better clinical outcomes and greater patient acceptance has been adopted.
Conclusions: Our data, obtained in an office setting without injectable anesthetic or IV sedation, indicate that monopolar RF for skin tightening is ver safe procedure. The treatment algorithm and tips have evolved over several years leading to increased safety and efficacy. Side effects are infrequent, self-limited, and minor, comparing favorably to other nonablative devices utilized for facial rejuvenation.

Study Design: A prospective, controlled study was performed in 5 adults with PWS using a frequency-doubled Nd:YAG laser (Excel V; Cutera Inc, Brisbane, CA) in 4 quadrants, using spot sizes of 6 to 10 mm, fluences of 4.8 to 9 J/cm2, and pulse durations of 3 to 6 ms. An adjacent control area was not treated. Each was assessed immediately posttreatment for purpura and edema and at 1 month for PWS color, size, texture, and thickness. Skin biopsies obtained immediately after and at 1 month posttreatment were evaluated.
Results: All treatment quadrants displayed purpura. At 1-month follow-up, all treatment quadrants showed at least 1 grade of color improvement, from a minimum of 1% to 25% to a maximum of 51% to 75% improvement (12/20 quadrants with 1%-25% improvement, 3/20 with 26%-50%, 5/20 with 51%-75%, and 0/20 with 76%-100%). Histologic evaluation of treatment quadrants revealed vascular changes ranging 0.35 to 4 mm in depth. Immediately posttreatment, thrombi and extravasated red blood cells were observed in treatment quadrants. Histology at 1 month revealed decreased number and diameter of vessels in treatment quadrants (superficial vessels decreased by mean 1.1 vessels per section [13%], and diameter by 3.0 μm [47%], midlevel vessels decreased in number by 2.3 [20%], diameter by 2.42 μm [25%], and deep vessels decreased in number by 1.5 [83%], and diameter by 7.44 μm [88%]).
Conclusions: A single treatment with a short pulse width, frequency-doubled Nd:YAG laser resulted in safe and effective improvement of PWS, with up to 75% improvement in color observed at 1 month. Histologic evaluation demonstrated vascular injury at depths of 0.35 to 4 mm with a reduction in vessel number and size at multiple dermal levels.

Oral and Topical L-Phenylalanine, Clobetasol Propionate, and UVA/Sunlight - A New Study for the Treatment of Vitiligo
Francisco Camacho, MD and Jose Mazuecos, MD| |
AIM: To demonstrate the effectiveness of topical and oral L-phenylalanine in combination with light plus 0.025% clobetasol propionate at night.
PATIENTS AND METHODS: We have performed an open trial on a group of 70 patients with evolutive vitiligo. Participants were treated with oral (100 mg/Kg/day) and tropical (gel at 10%) L-phenylalanine, exposed to sunlight (spring-summer) or UVA lamps (autumn-winter), and given 0.025% clobetasol propionate at night. All patients were revisited every 6 months while in the study, with a maximum of 4 revisits. Biochemical studies were performed at the beginning of the treatment and at each revisit.
RESULTS: Overall, 90.9% of participants showed improvement, with 68.5% of patients achieving an improvement of 75% or more. This 75% improvement rate was reached 87.9% of the time on the face, 60.4% on the trunk, and 54.6% on the limbs. However, there was a moderate response to the treatment in patients with focal and segmental vitiligo. There was a slight additional improvement in patients receiving UVA lamp light. No biochemical abnormalities were found in any patients.
CONCLUSION:L-phenylalanine in combination with 0.025% clobetasol propionate and sunlight during sunny months or UVA lamps in winter, appears to improve evolutive vitiligo without side effects, and therefore is especially recommended on the face or for children.

Methods: Five patients were enrolled in the study. All patients presented with epidermal pigmented lesions on the arms, hands, chest, or legs. Patients were all female with a mean age of 59 years. At the initial evaluation, baseline pigment readings were determined with a pigment meter. Test spots were performed with escalating doses of alexandrite laser (ClearScan ALX, Sciton, Palo Alto, CA) deployed by a 7-mm spot equipped with a 30 mm x 30 mm scanner and a 10-ms pulse duration. Contact cooling was used, and temperature was maintained at 18°C to 20°C. Patients returned 4 to 7 days after test spots for evaluation for the purpose of optimizing settings. The highest settings that allowed for epidermal preservation and crusting of the hyperpigmented lesions were applied for the remainder of the treatment zones. Determinations of improvement were made by evaluation of photographs with standard settings using polarized and nonpolarized images. At each appointment, baseline pigment measurements were made to ensure there were no significant changes between treatment sessions. Two treatment sessions were performed approximately 4 weeks apart, and the final evaluation was 3 months after the final treatment.
Results: Evaluation by a panel of blind observers determined a mean improvement of approximately 30%. Darker lesions responded better than lighter lesions. So-called low-contrast lesions performed the poorest. Pain was approximately 2/10 with the use of 5% lidocaine numbing cream applied approximately 45 minutes before each procedure. Pain was most severe where there was underlying hair.
Conclusion: A long-pulse alexandrite laser equipped with contact cooling can achieve significant pigmentation improvement.

Port-wine stain (PWS) is the second most common congenital vascular malformation characterized as ectatic capillaries and venules in the dermis that clinically appears as a deep red to purple patch on the skin. Typically, PWS progressively darken and may become hypertrophic or nodular without treatment. There are several treatment options available for PWS from topical antiangiogenic agents to laser therapies. Vascular-specific lasers are the gold standard in treating PWS and classically pulsed dye lasers are usually the treatment of choice. However, some patients with PWS are recalcitrant to PDL and may require a combination of treatment methods. Nonetheless, even with the advancements in laser therapies utilized today, it is can be difficult to achieve complete clearance of the PWS. Thus, new innovations for treating recalcitrant PWS are underway in order to improve overall patient treatment outcomes.

Increased understanding of psoriasis has led to a shift in treatments from non-specific immunosuppressants to targeted biologics. Studies in psoriasis have demonstrated minimal risk and substantial benefit. As a result, dermatologists and patients are more frequently choosing biologics as first-line treatments for moderate-to-severe disease as our biologics options have recently increased.
Hair Removal with the 3-msec Alexandrite Laser in Patients with Skin Types IV-VI: Efficacy, Safety, and the Role of Topical Corticosteroids in Preventing Side Effects

A number of drugs can cause cutaneous hyperpigmentation through a variety of mechanisms. The pigment is comprised of dermal deposits of the drug and its metabolites, often combined with melanin and hemosiderin. Minocycline and amiodarone are among the most common medications to cause skin-induced pigmentation. Affected individuals generally develop slate-gray pigmentation in affected sites. Treatment with various Q-switched lasers has been shown to be effective at removing drug-induced pigmentation. The author presents a man with amiodarone pigmentation of the face who responded to treatment with the Q-switched neodymium:yttrium-aluminum-garnet (Nd:YAG) laser.

Objective: The objective of this study was to determine the role of immunity and inflammation in androgenetic alopecia in women and modulate therapy according to inflammatory and immunoreactant profiles.
Materials and Methods: 52 women with androgenetic alopecia (AA) underwent scalp biopsies for routine light microscopic assessment and direct immunofluroescent studies. In 18 patients, serologic assessment for antibodies to androgen receptor, estrogen receptor and cytokeratin 15 was conducted.
Results: A lymphocytic folliculitis targeting the bulge epithelium was observed in many cases. Thirty-three of 52 female patients had significant deposits of IgM within the epidermal basement membrane zone typically accompanied by components of complement activation. The severity of changes light microscopically were more apparent in the positive immunoreactant group. Biopsies from men with androgenetic alopecia showed a similar pattern of inflammation and immunoreactant deposition. Serologic assessment for antibodies to androgen receptor, estrogen receptor or cytokeratin 15 were negative. Combined modality therapy with minocycline and topical steroids along with red light produced consistent good results in the positive immunoreactant group compared to the negative immunoreactant group.
Conclusion: A lymphocytic microfolliculitis targeting the bulge epithelium along with deposits of epithelial basement membrane zone immunoreactants are frequent findings in androgenetic alopecia and could point toward an immunologically driven trigger. Cases showing a positive immunoreactant profile respond well to combined modality therapy compared to those with a negative result.

The Phototoxic and Photoallergy Potential of Clindamycin Phosphate 1.2%/ Tretinoin 0.025% Gel for Facial Acne: Results of Two Single-Center, Evaluator-Blinded, Randomized, Vehicle-Controlled Phase 1 Studies in Healthy Volunteers
John Murray MDa and Aaron Potts BScb| |
OBJECTIVES: Two-phase I studies were conducted to evaluate the phototoxic and photoallergic potential of clindamycin/tretinoin gel.
METHODS: Study 1 (phototoxic) (n=37) and Study 2 (photoallergic) (n=58) were single-center, evaluator-blinded, randomized, vehicle-controlled, phase 1 studies conducted in healthy volunteers. In Study 1, clindamycin/tretinoin gel patches, vehicle gel patches and blank patches (no gel) were applied concurrently for 24 hours to naïve sites. After patch removal, sites were irradiated with 16 joules/cm2 of ultraviolet A light (UVA) then 0.75 minimal erythema dose (MED) of UVA/ultraviolet B light (UVB), the same irradiation protocol followed by 15 joules/cm2 of visible light (VIS), or served as non-irradiated controls. Study 2 examined the effect of repeated drug exposure and involved an induction period (6 repeat phases at the same body sites during which clindamycin/tretinoin gel and vehicle gel patches were applied for 24 hours, removed and sites irradiated with UVB +/- VIS), followed by a rest period (10 to 17 days), then a challenge period that used the protocol described for Study 1. In both studies, inflammatory responses and other cutaneous effects were evaluated at 1, 24, 48, and 72 hours after patch removal.
RESULTS: No subject experienced any adverse events in Study 1 (phototoxic). One subject in Study 2 (photoallergic) experienced AEs (diffuse erythema; mild application site irritation at one each of UV/VIS-irradiated clindamycin/tretinoin gel and vehicle gel patch sites) considered definitely related to study product that resulted in discontinuation from the study. Data from Study 1 and the challenge phase from Study 2 showed most subjects had no visible inflammatory reaction to clindamycin/tretinoin gel after irradiation.
CONCLUSIONS: Clindamycin/tretinoin gel has a favorable safety profile following UV/visible irradiation and a low potential for phototoxicity and photoallergenicity.

Dark skin offers some protection from ultraviolet (UV) light. However, there is considerable heterogeneity in skin of color, a phenomenon that is accentuated by mixed heritage. Ethnicity does not confer skin type anymore. People of color do experience sunburn, and from a biological point of view, all skin types appear to be sensitive to UV-induced DNA damage, with an inverse relationship between skin color and sensitivity to UV light.
Our population is changing rapidly, and within the next few decades minority populations will become the majority. It is therefore imperative to educate both physicians and patients on the perceived immunity against cutaneous malignancies, the need for sun protection, and the clinical signs of skin cancer in non-Caucasian people, so that future unnecessary mortality can be avoided.

Randomized, Split-Face/Décolleté Comparative Trial of Procedure Enhancement System for Fractional non-Ablative Laser Resurfacing Treatment
Deanne Mraz Robinson FAAD MDa,b and Ashton P. Frulla RNb| |
INTRODUCTION: A topical proprietary procedural enhancement system (PES) containing a combination of active ingredients including a tripeptide and hexapeptide (TriHex Technology™, Alastin Procedure Enhancement Invasive System, ALASTIN Skincare™, Inc., Carlsbad, CA) has been used successfully to aid in healing and improve symptomatology following resurfacing procedures.
METHODS: PES (Gentle Cleanser, Regenerating Skin Nectar with TriHex Technology™, Ultra Nourishing Moisturizer with TriHex Technology™, Soothe + Protect Recovery Balm, Broad Spectrum 30+ Sunscreen) was compared to a basic regimen (Aquaphor™, Cerave™ cleanser, Vanicream™, Alastin Broad Spectrum 30+ Sunscreen) in a split face/ décolleté trial following fractional non-ablative thulium-doped resurfacing treatment to the face or décolleté. The skin was pre-conditioned and treated during and after the procedure using the two regimens.
RESULTS: A blinded investigator rated the PES statistically superior to the basic regimen on healing post-laser treatment on day 4 based on lentigines, texture, and Global Skin Quality. Subjects also reported ‘better looking and feeling’ skin on the PES side.
CONCLUSION: PES appears to improve healing post-non ablative thulium-doped resurfacing treatment to the face/décolleté in comparison with standard of care.

Case Report: A 65-year-old woman suffered from an overlapping form of pityriasis lichenoides (OPL) for 5 years. Several initial acute episodes were controlled by successive courses of oral antibiotics, topical corticosteroids, and/or psoralen ultraviolet light-A (PUVA) therapy. The disease progressively evolved to a more chronic form. Topical immune response modifiers and corticosteroids, as well as PUVA, ultraviolet light-B (UVB), methotrexate, dapsone, and cyclosporine were introduced, but all proved ineffective. Due to the therapy multiresistance, 2 weekly injections of etanercept were administered. After 2 months, a marked improvement was observed in regards to the patient’s pruritus and inflammation. No treatment-related adverse effects were observed. Therapy was continued for 4 months without any new lesion development. However, 1 month after stopping treatment new OPL lesions recurred.
Conclusion: At the time of publication, this is the first report of the effectiveness of etanercept in OPL. This drug might be consid- ered as a therapeutic alternative for treatment multiresistant OPL.
Single Blind, Randomized, Controlled Trial of a Lightening Product With and Without Iontophoresis versus Tretinoin and Vehicle for Hyperpigmentation
Molly Wanner MD MBA,a Neil Houston BA,b Emilia Javorsky MPH,c Minsheng Yuan MD,d
Maria Alora-Palli MD,e Alexa B. Kimball MD MPHf
OBJECTIVE: To compare the efficacy of a new skin lightening product with and without iontophoresis to a known effective product (tretinoin) and placebo on hyperpigmentation caused by lentigines and/or melasma. Secondary objectives included an assessment of the product’s effects on the appearance of rhytides and roughness.
METHODS AND MATERIALS: Eighty subjects were randomized into one of four treatment groups: proprietary lightening product, proprietary lightening product with iontophoresis, tretinoin 0.05% cream, or vehicle control. Seventy-four subjects completed all study visits. Blinded assessments of subjects were performed at each visit under ambient and Wood’s light.
RESULTS: The proprietary skin lightening product improved facial hyperpigmentation versus placebo under ambient light (P = 0.05) and Wood’s lamp (P = 0.01) examination. Tretinoin also improved facial hyperpigmentation versus placebo under Wood’s lamp (P = 0.01). The proprietary product was better tolerated than tretinoin, with fewer subject reported side effects.
CONCLUSION: The investigational product was effective and may be better tolerated than tretinoin cream.

Quantitative & Qualitative Evaluation of the Efficacy of a 1440 nm Nd:YAG Laser With Novel Bi-Directional Optical Fiber in the Treatment of Cellulite as Measured by 3-Dimensional Surface Imaging
Bruce Katz MD| |
OBJECTIVE: To evaluate the safety and efficacy of a single cellulite treatment using an Nd:YAG 1440-nm laser delivered with a special fiber delivery system and temperature control.
METHODS: Women with cellulite on their thighs and buttocks were enrolled in a prospective Institutional Review Board–approved study. Subjects were 15 healthy females of all Fitzpatrick Skin types with cellulite (grades II-III). A single treatment was performed with an average of seven 5 x 5 cm squares treated per leg. Evaluations with 2D and 3D imaging, patient and blinded evaluator scales as well as skin histology were performed at baseline, 3 and 6 months post treatment.
RESULTS: In the 2D photographs, blinded evaluators were able to identify treated photographs versus baseline in 90% of cases and the number of sites with improvement in contour irregularities was 94%. With 3D imaging, the average decrease in skin depressions (dimples) was 49% at 6 months and 66% of patients showed improvement in overall skin contour at 6 months follow-up. Patient and physician satisfaction scores were high and no adverse events were reported.
CONCLUSION: The Nd:YAG 1440 nm laser with a special fiber delivery system produced significant improvement in cellulite with one treatment after 6 months of follow up. There were no adverse events.

Access of Efinaconazole Topical Solution, 10%, to the Infection Site by Spreading Through the Subungual Space
Boni E. Elewski MD,a Richard A. Pollak, DPM MS,b Radhakrishnan Pillai PhD,c Jason T. Olin PhDd| |
METHODS: 11 patients (mean age 48.5 years) were entered with clinically determined onychomycosis. Presence of fungal infection was confirmed by KOH testing in eight patients. Two separate applications of vehicle (with fluorescein incorporated for better visualization) were applied at the hyponychium, avoiding application to the exterior nail plate surface. Affected nails were later clipped to allow examination of the nail bed and further examination of the underside of the nail. Spread of formulation was assessed under visible and UV light conditions by photographing target toenails after vehicle application, and after nail clipping.
RESULTS: Assessments under both visible and UV light indicated that the vehicle had spread into the subungual space, with deposition of flourescein wherever vehicle had reached, including in the nail bed. Nail clippings also indicated deposition to the underside of the nail plate.
LIMITATIONS: The relative contributions of spreading into the subungual space, or permeation through the nail plate to the efficacy of efinaconazole topical solution, 10% in treating onychomycosis were not assessed.
CONCLUSIONS: This study suggests that the vehicle developed for efinaconazole topical solution, 10%, when applied at the hyponychium, spreads into the subungual space between the nail plate and nail bed, reaching the site of infection.

Evaluation of the Chemopreventative Effects of ALA PDT in Patients With Multiple Actinic Keratoses and a History of Skin Cancer
Objective: To evaluate the time to development of new non-melanoma skin cancers (NMSC) within one year of ALA-PDT treatment in immunocompetent patients with AK and a history of skin cancer.
Methods and Materials: One hundred forty anatomic sites in 114 patients were treated with topical ALA for a 1 to 3 hour incubation period followed by photodynamic therapy (PDT) with a blue light. All new NMSCs within the treatment areas were recorded over a 1-year observational period.
Results: Eighty-three anatomic sites (59%) did not develop new skin cancers within 1 year. Additionally, 92%, 78%, and 64% of anatomic sites were free of new skin cancers at 3, 6, and 9 months after treatment was initiated. Although approximately 41% of patients treated on both the scalp and face developed new skin cancers within 1 year of treatment, the average time to develop skin cancer was longer for the face (7.09 months) than for the scalp (5.34 months).
Conclusion: In patients with a history of NMSC and multiple AKs, ALA PDT may be a valuable option for the prevention and delay of new NMSCs.

Evaluation of the Safety and Efficacy of a Novel 1440nm Nd:YAG Laser for Neck Contouring and Skin Tightening Without Liposuction
Deborah S. Sarnoff MD FAAD FACP| |
OBJECTIVE: To test the safety and efficacy of a pulsed 1440nm Nd:YAG wavelength and side-firing fiber for the treatment of subcutaneous fat and skin laxity associated with the aging neck.
METHODS: Twenty-four subjects aged 40 to 65 years underwent laser lipolysis of the submental and anterior cervical areas. An average of 1205J per 5x5cm square was delivered, with a maximum internal temperature setting of 47 degrees C. Cervicomental Angle Score (CAS), Global Aesthetic Improvement Scale (GAIS), subject and investigator satisfaction, and safety were assessed.
RESULTS: At six months post-treatment, 79% of subjects had a significant improvement in the CAS (P<.001) and 79% demonstrated an improvement on the GAIS. Clinical improvement was marked and evident for all but one subject, with physician and patient satisfaction scores indicating overall satisfaction with the procedure and outcomes. Adverse events were mild and transient with no incidence of burns, seromas, hematomas, infection, or nerve damage.
CONCLUSION: The 1440nm Nd:YAG device with the side-firing fiber was safe and effective for the treatment of subcutaneous fat and skin laxity in the neck. This device offers an alternative to selected individuals aged 40 and over who do not wish to undergo rhytidectomy.

Objective: To evaluate the effectiveness, tolerability, and patient-reported outcomes of combination etanercept plus NB-UVB phototherapy in moderate to severe plaque psoriasis.
Methods: This 12-week, single-arm, open-label study evaluated the combination of etanercept 50 mg twice weekly and NB-UVB thrice weekly in 86 patients. The primary outcome measure was ≥75% improvement from baseline in the Psoriasis Area and Severity Index (PASI 75). Other measures included PASI 90, PASI 100, and the Dermatology Life Quality Index (DLQI).
Results: At week 12, 26.0% achieved PASI 100, 58.1% achieved PASI 90, and 84.9% of patients achieved PASI 75. Mean improvement from baseline in DLQI was 84.4%. No unexpected, untoward adverse events were noted.
Conclusions: A 12-week course of etanercept plus NB-UVB phototherapy was well tolerated and produced clinically meaningful improvements in signs and symptoms of moderate to severe plaque psoriasis and in patient-reported outcomes. Further investigation of the safety and efficacy of the use of such combination for this indication in controlled clinical trials would be of interest.

Background: The use of intense pulsed light (IPL) for facial rejuvenation had been the topic of many studies. However, few of them
discussed quantitative changes in extracellular matrix proteins after IPL therapy.
Objective: To objectively quantify the histological changes in extracellular matrix proteins after IPL treatment for facial wrinkles.
Methods: Biopsy specimens were obtained from the periocular area of six volunteers of Fitzpatrick skin type III–IV and Glogau's class I–III wrinkles. They were subjected to three months of IPL treatment (six sessions at two-week intervals). Using histological and immunostaining analysis coupled with computerized morphometric analysis, quantitative evaluation of collagen types I, III and VII, newly synthesized collagen, total elastin and tropoelastin was performed for skin biopsies at baseline, end of treatment, and three months post-treatment.
Results: Clinical assessment of volunteers did not show clinically noticeable improvement in facial wrinkles after IPL treatment. Furthermore, quantitative evaluation of extracellular matrix proteins showed no statistically significant changes (P>0.05) in response to IPL treatment.
Conclusion: Although 50 percent of volunteers showed mild improvement in skin texture at the end of IPL treatment, none of them reported improvement in skin tightening or wrinkles. No statistically significant histological changes were observed three months post IPL treatment.

OBJECTIVE: We evaluate disease characteristics and treatment response variation in the moderate-to-severe psoriasis population based on PsA history.
METHODS: Simple-measure for assessing psoriasis activity (S-MAPA) was used to retrospectively analyze treatment responses.
RESULTS: 191 moderate-to-severe psoriatic patients, 58 with and 133 without rheumatologist-diagnosed PsA were analyzed. Regardless of PsA history, S-MAPA improvement was similar with biologic monotherapy (46.2 versus 44.1; P=0.74), traditional systemic monotherapy (62.29 versus 38.12; P=0.22), and combination treatments (64.62 versus 52.71; P=0.40) after 12 weeks. PsA patients on biologic monotherapy experienced a higher infection rate than patients without PsA (0.57% versus 0.19%; P=0.01). PsA patients experienced more adverse events (AEs) associated with traditional systemic monotherapy than biologic monotherapy (3.25 versus 1.04; P=.001).
LIMITATIONS: The relatively small PsA cohort was the primary limitation.
CONCLUSIONS: Patients with moderate-to-severe psoriasis responded similarly to all treatments independent of PsA history. PsA patients received more overall treatments and more biologic monotherapy prescriptions. PsA patients had a greater infection risk on biologic monotherapy compared to those without PsA, and greater adverse events risk on traditional systemic monotherapy compared to biologic monotherapy.

PURPOSE: To determine the frequency of prescribing calcipotriene and other psoriasis drugs in combination.
METHODS: Visits with a sole diagnosis of psoriasis were selected from 1990-2010 data from the National Ambulatory Medical Care Survey. The number of combination therapies used, the leading therapies in each class of medications, and the leading types used in combination were analyzed.
RESULTS: About 10.2 million of 20.3 million psoriasis visits used multiple treatments. The mean number of prescribed medications increased over time (P=.0003). The top 10 treatments included 6 topical steroids, calcipotriene, 2 other topicals, and methotrexate. The most common combinations were topical steroid plus other topical (15.0%), multiple topical steroids (11.5%), topical steroid plus vitamin D analogue (9.7%), and topical steroid plus systemic treatment (6.9%). Vitamin D analogues and systemic treatments were prescribed with increasing frequency over time, while fewer topical steroids were used, and use of other topicals did not change significantly.
LIMITATIONS: Visits with multiple diagnoses had to be excluded to ensure that the medications listed were for psoriasis.
CONCLUSIONS: Combination therapy is the most common way to treat psoriasis in the United States. The wide range of combination therapies prescribed may reflect increased attention to individualization of treatment to match patients’ diverse preferences.

Methods: In this randomized, double-blinded, placebo-controlled split-face study, 20 subjects with bilateral facial telangiectasia were treated with a pulsed dye laser (PDL) device at purpuric settings. The test articles, a gel containing vitamin K oxide and placebo (vehicle), were each randomly assigned to one side of the subject’s face. Subjects applied the test articles twice a day for the following 9 ± 1 days. Improvement in both focal and general field purpura on each side of the face was assessed by the investigator using photographs. A scale of -100% (worsening) to 100% (improving) was used to rate photos against a baseline photograph obtained 15–30 minutes after treatment with the PDL device.
Results: Resolution of the field of purpura was consistently greater with the vitamin K oxide gel after the second day of treatment. The greatest difference between the vitamin K oxide gel and placebo scores occurred on the fourth day after treatment. Although differences in active versus placebo scores did not reach statistical significance during the nine-day study period, a trend toward faster resolution of purpura with the active product was seen. Treatment-related adverse effects were not observed in any subject.
Conclusion: Vitamin K oxide gel appears to hasten the resolution of pulsed dye laser-induced purpura in subjects being treated for bilateral facial telangiectasia, and may well be useful in accelerating resolution of facial bruising from other cosmetic procedures such as fillers used for soft-tissue augmentation as well as other types of cutaneous surgical procedures.
Treatment of Inverse/Intertriginous Psoriasis: Updated Guidelines from the Medical Board of the National Psoriasis Foundation
Hasan Khosravi MD,a Michael P. Siegel PhD,b Abby S. Van Voorhees MD,c and Joseph F. Merola MD MMSca,d| |
Inverse or intertriginous psoriasis commonly involves skin fold areas including the axillae, perianal skin, intergluteal cleft, inframammary, genital/inguinal, abdominal, and retroauricular folds. After reviewing the literature for new treatments, a task force was convened to update a consensus on inverse psoriasis therapy. Short-term treatment continues to be low-potency topical steroids. In order to avoid steroid-induced adverse effects, long-term therapy includes topical immunomodulators, calcitriol, and calcipotriene. Second and third-line therapies include antimicrobials, emollients, and tar-based products. Inverse psoriasis resistant to topical therapy has been shown to respond to botulinum toxin injections, excimer laser therapy, and certain systemic agents (such as anti-TNF and anti-IL12/IL23 therapy). Based on promising results from case reports and prior clinical experience, these systemic agents should be strongly considered in inverse psoriasis resistant to topical therapy. However, they need further evidence-based evaluation. The use of randomized trials and objective severity indices may allow for more robust therapeutic data.

Objective: To ascertain whether fluorescence imaging improves the clinical tumor border assessment by investigating the consistency between tumor size determination by MMS, clinical assessment, and fluorescence imaging.
Methods: Eighteen patients with histologically verified nodular BCCs on the face scheduled for MMS were included in the study. The night before the surgical procedure, 5-aminolevulinic methyl ester cream was applied to the lesion. The following morning, tumor borders were determined clinically (clinical size), after illumination with Wood’s light (fluorescence size), and by the tumor defect left on the skin surface following removal of the MMS specimen (Mohs size).
Results: The median tumor sizes were 93.05 mm2 (Mohs size), 61.05 mm2 (clinical size), and 72.75 mm2 (fluorescence size). The interclass correlation coefficients between Mohs size and fluorescence size was 0.984 and Mohs size and clinical size was 0.752.
Conclusion: Tumor border estimation by fluorescence imaging and clinical assessment underestimate the genuine tumor size determined by MMS; however, the fluorescence size showed a higher degree of consistency with the Mohs size than did the clinical size.

Evaluation of Clinical Improvement in Acne Scars and Active Acne in Patients Treated With the 1540-nm Non-Ablative Fractional Laser
María José Isarría MD, Paloma Cornejo MD, Estefanía Muñoz BSc, Josefina Royo de la Torre MD, Javier Moreno Moraga MD| |
Introduction. Acne is a characteristic condition of puberty; however, adults who continue to have acne outbreaks frequently attend dermatology clinics. Two conditions—active acne and residual scarring—often co-occur in these patients. The objective of the present study was to evaluate the improvement in scarring and active acne after treatment with a 1540-nm erbium: glass fractional laser.
Material and Methods. The authors treated 20 patients with acne and scarring. Each patient received panfacial treatment in four sessions with a 1-month interval between sessions. Patients, the treating physician and a blinded observer evaluated the results in four areas: improvement in scars, improvement in pores, improvement in acne, and improvement in sebum secretion. Improvements were graded using the Global Aesthetic Improvement Scale. The evaluation was made 12 weeks after treatment finished.
Results. Patients presented an improvement in both acne and scars. In 80 percent of cases, patients felt that the appearance of the scars had improved, and the improvement was classified as very much improved in 40 percent. In 85 percent of cases, patients felt that active acne had improved, and the improvement was classified as very much improved in 45 percent. Pore size was evaluated as improved by 75 percent of patients. Sebum secretion improved in 80 percent of cases.
Conclusion. A 1540-nm non-ablative fractional laser provides effective treatment of acne scars. Patient satisfaction is high and active acne lesions improve significantly. Treatment of this mixed condition (scarring and active acne) with a single device is reliable, with a favorable safety profile and a high degree of patient acceptance.

OBJECTIVE: To review successful treatments of Hailey-Hailey, synthesize the evidence, and provide recommendations for therapy. Findings: The best evidence exists for treatment with topical steroids and topical antimicrobials. Refractory disease has shown the most benefit with addition of oral antibiotics, excisional procedures and botulinum toxin A. Other therapies are described but with much less supporting evidence.
CONCLUSIONS: Herein we review the literature to identify successful treatments for Hailey-Hailey disease. We have outlined the treatments with the most evidence. The difficult nature of treating this disease requires that clinicians approach each patient differently. The literature shows that no one regiment works for all patients.

OBJECTIVES: To review the use of PDL for the treatment of MC.
MATERIALS AND METHODS: A search of the National Library of Medicine’s PubMed Database and the SCOPUS Database was performed to find articles that detailed the treatment of MC with PDL.
RESULTS: Eight articles met criteria for inclusion in this review. These articles represented 161 patients with over 4200 MC lesions that were treated with PDL. Each article was reviewed and summarized in a table.
LIMITATIONS: The main limitation of this review is the small number of published studies, which reflects the importance of this review of the dermatology literature.
CONCLUSIONS: PDL offers a novel and effective treatment for MC. However, the articles reviewed herein suggest PDL is a safe, effective, quick and well-tolerated treatment for clearing MC lesions that does not cause scarring or permanent pigment change.

Split-Face Comparison of Ultrapulse-Mode and Superpulse- Mode Fractionated Carbon Dioxide Lasers on Photoaged Skin
Background: Both ultrapulse-mode and superpulse-mode fractional CO2 lasers (UPCO2 and SPCO2) could be successfully used
in treating photoaged skin.
Objective: This evidence-based study was intended to compare the therapeutic and adverse effects of UPCO2 and SPCO2 in treating photoaged skin in Chinese subjects.
Methods: Eighteen Chinese subjects with Fitzpatrick skin type IV were enrolled in a randomized, split-face trial. Subjects received SPCO2 on one half of the face and UPCO2 on the other half. Before and after photos, skin color, epidermal water content, sebum level, periorbital wrinkles, skin roughness, and self-esteem questionnaires were used.
Results: Global evaluation and subjects' self-esteem assessments showed a similar trend at 1-month and 3-month follow-up visits on both sides. The UPCO2 laser has a shorter downtime of 6.25±2.71 days compared with 6.41±2.67 days for SPCO2, but has a higher incidence of edema, spot bleeding, prolonged redness and postinflammatory hyperpigmentation. More subjects prefer SPCO2 treatment because of similar efficacy and fewer adverse effects.
Conclusion: The effectiveness of the SPCO2 laser in treating photoaged skin is very similar to the UPCO2 laser, with less erythema, but more crusting and longer downtime.

The Presence of an Air Gap Between the Nail Plate and Nail Bed in Onychomycosis Patients: Treatment Implications for Topical Therapy
Aditya K. Gupta MD PhD FRCPC FAADa,b and Radhakrishnan Pillai PhDc| |
OBJECTIVE: To evaluate the ability of efinaconazole vehicle solution to reach the site of toenail onychomycosis through application to the hyponychium or hyponychium and dorsal nail surface, and assess the impact of the air gap between the nail plate and nail bed.
METHODS: Twenty-three participants with moderate to severe, mycologically-confirmed onychomycosis were enrolled (mean age, 48.5 years). Two separate applications of vehicle solution containing fluorescein for visualization were applied at the hyponychium or hyponychium and dorsal nail surface. Affected nails were later clipped to allow examination of the nail bed and further examination of the ventral surface of the nail. Spread of formulation was assessed under visible and UV light conditions by photographing target toenails after vehicle application and after nail clipping.
RESULTS: There was a positive correlation between the size of the air gap and degree of affected nail involvement (R2=0.064). Assessments under both visible and UV light indicated that the vehicle had spread to the site of infection, with deposition of fluorescein wherever vehicle had reached, irrespective of application methodology or size of air gap. Nail clippings also indicated absorption into the ventral surface of the nail plate.
LIMITATIONS: The relative contributions of subungual versus transungual application of drug to the nail plate to the efficacy of efinaconazole topical solution, 10% in treating onychomycosis were not assessed.
CONCLUSIONS: This study suggests that the low surface tension vehicle developed for efinaconazole topical solution, 10% can reach the site of infection by application to the hyponychium, dorsal or ventral nail surface and nail folds. This multidirectional approach to drug delivery at the site of fungal infection may contribute to the magnitude of efficacy seen in clinical trials.

Many topical medications are available for the treatment of papulopustular rosacea. While treatments contain metronidazole, azelaic acid, or sodium sulfacetamide-sulfur as the active ingredient, the composition of the vehicle formulations varies widely. These vehicles come in gels, creams, lotions and foams; some ingredients are common to many vehicles, while some vehicles contain unique ingredients designed to optimize skin penetration and delivery of the active drug to its target. Vehicles can also influence tolerability, which is always a concern in patients with heightened skin sensitivity, and compliance, which is typically lower for topical treatments than oral treatments. Ideally, the vehicle of any rosacea treatment should enhance drug delivery, be nonirritating and be easy to use. Ingredients that help repair barrier function are also desirable. This review will focus on the key components of the vehicles from the most commonly used topical therapies for papulopustular rosacea and how vehicle formulations influence the delivery of active ingredient, skin barrier repair, tolerability and compliance.

The Treatment of Melasma With Topical Creams Alone, CO2 Fractional AblativeResurfacing Alone, or a Combination of the Two: A Comparative Study
Mario A. Trelles MD PhD, Mariano Velez MD, Michael H. Gold MD| |
Patients and Methods: Thirty females with melasma, mean age of 38 years, skin types II–IV, were allocated to three groups: group A received treatment with Kligman’s formula maintenance topical cream program; group B, CO2 fractional resurfacing using high power, fixed pulse width and low frequency; and group C, both laser and maintenance topical cream treatment. Subjective patient and clinician assessments based on melasma area severity index (MASI) scores were made at baseline, one, two, six and 12 months, and the satisfaction index (SI) and overall efficacy calculated.
Results: All patients completed the study. The SI and overall efficacy in groups A, B and C were 100% at one month in all groups but progressively decreased in further assessments except for group C in which better scores were maintained throughout. MASI scores for group C were statistically significantly improved compared to A and B at six and 12 months (P<0.001 for both).
Conclusion: The fractional CO2 laser and topical cream regimen produced good, well-maintained results in melasma treatment compared with the monotherapy groups.

OBJECTIVE: To characterize psoriasis treatments by patients' types of payment in the US outpatient office setting.
METHODS: Using the National Ambulatory Medical Care Survey (NAMCS), a large survey that samples outpatient office visits to US non-federally funded physicians, visits linked with sole diagnoses for psoriasis (ICD-9-CM: 696.1) were identified. There were 545 unweighted records. The types and number of treatments prescribed at these visits were categorized by expected major payment type to be used for the visit.
RESULTS: Mainstay psoriasis therapies such as vitamin D analogs and clobetasol were prescribed regardless of payment type. Retinoids were also within the most frequently prescribed psoriasis medications for all payment types, however they were less frequently prescribed than vitamin D analogs. Payment type did not have a significant effect on the number of medications prescribed at psoriasis visits.
LIMITATIONS: Data on treatment adherence and filling of prescriptions are not included in the NAMCS database.
CONCLUSION: Prescribing patterns for psoriasis medications are similar across payment type. Additional factors appear to modulate therapy choice for patients with psoriasis.

Background: Hyaluronic acid (HA) gels are commonly injected into the skin to lift rhytides and to improve facial appearance. The different processes used in their manufacture and formulation yield products with unique physical characteristics that play an important role in predicting their clinical performance.
Objective: The following rheologic evaluation was performed to objectively measure the physical characteristics of HA dermal filler products derived from similar bacterial sources and containing the same butanediol diglycidyl ether cross-linker, but formulated using different manufacturing techniques. The objective of this study was to evaluate the physical characteristics of two distinct families of HA products, thereby providing clinicians with a greater understanding of these products' attributes and the ability to optimize their use in the treatment of patients seeking facial rejuvenation.
Materials and Methods: The physical properties of commercially-available dermal fillers containing HA were evaluated using rheologic testing methods under clinically-relevant conditions. Additionally, light microscopy was used to assess the particulate nature of each product.
Results: The gels tested demonstrated a broad range of elasticity, firmness and viscosity. Light microscopy confirmed the particulate nature of each product and revealed HA particles of varying size and distribution.
Conclusion: This rheologic evaluation demonstrates that differences exist among the HA products tested including gel elasticity, viscosity, and the range and distribution of gel particle sizes. Understanding the distinct physical characteristics of different HA dermal fillers and how these characteristics may predict their clinical behavior can assist clinicians in achieving the desired results in patients seeking facial rejuvenation.

OBJECTIVE: We sought to determine the treatments most commonly prescribed and the performance of all systemic and surgical treatments used in hidradenitis suppurativa patients in Olmsted County, Minnesota, treated over a 40-year period.
METHODS: A retrospective chart review was performed to evaluate hidradenitis suppurativa treatments in 376 episodes with 115 Olmsted County patients seen by a clinician at Mayo Clinic in Rochester, Minnesota, between 1968 and 2008. Treatment episode outcomes were recorded from clinical notes for the 73 treatment episodes that had a follow-up period of more than 30 days.
RESULTS: Systemic antibiotics alone were prescribed most frequently in 70.0% of episodes. Systemic antibiotics alone improved 39 of 49 treatment episodes (79.6%), including 13 episodes (26.5%) when the disease was fully cleared. All 5 of 5 episodes (100%) of surgical treatment alone improved, including 4 (80%) in which the disease was fully cleared. Surgery in combination with systemic antibiotic treatment yielded improvement in 5 episodes (71.4%), with 2 episodes (28.6%) showing complete clearance.
CONCLUSION: Systemic antibiotics were the most frequently prescribed treatment type in 115 patients over a 40-year period. Both systemic antibiotic therapy and surgical treatment are effective in disease management.

OBJECTIVE: To determine whether racial or ethnic groups are treated differently for dyschromia. The secondary objective is to discover the main treatments used and determine trends over time in demographics.
METHODS: We searched the 1993-2010 National Ambulatory Medical Care Survey (NAMCS) for visits associated with a diagnosis of dyschromia (ICD-9 codes 709.00 or 709.09). The demographics and leading treatments were tabulated, and trends over time were assessed by linear regression.
RESULTS: There were about 24.7 million visits for dyschromia over the 18-year period. Among 5,531,000 patients with the sole diagnosis of dyschromia, there were 2,800 visits from females and 1,200 visits from males per 100,000 population. Females were more likely to receive prescription combination therapy for dyschromia than males by a ratio of 10 to 1. Leading treatments overall prescribed by dermatologists included hydroquinone, topical corticosteroids, and retinoids. Asians were 27% more likely to receive a combination therapy than non-Asians. African Americans and Hispanics were less likely to have a procedure performed for dyschromia.
LIMITATIONS: Data are based on a number of ambulatory care visits, which does not allow direct estimation of prevalence.
CONCLUSIONS: Dyschromia is a significant concern for many patients, and this is especially true among patients of color. Treatment for dyschromia is influenced by skin type, and thus ethnic or racial groups are treated differently. Studies have shown that combination therapy may offer better results than a single medication for hyperpigmentation disorders. Combination agents may be underutilized in African Americans and Hispanics for dyschromia.

Background: Combination therapy is a common and appropriate treatment strategy for moderate-to-severe psoriasis, as it provides for enhanced efficacy and decreased toxicity compared to the use of a single agent. Acitretin is an effective oral retinoid for psoriasis that seems to find its greatest value when complemented by other topical and systemic treatments.
Objective: The primary aim of this study is to assess the use of acitretin in combination with other treatments for psoriasis.
Methods: We assessed the use of acitretin for the treatment of psoriasis using nationally representative survey data from the National Ambulatory Medical Care Survey (NAMCS).
Results: Among visits where acitretin was listed in the NAMCS, other psoriasis medications were co-prescribed in 62 percent of visits. The co-prescribed medications included topical corticosteroids (51%), calcipotriene (31%), biologics (6%), cyclosporine (5%), methotrexate (5%) and tazarotene (2%).
Conclusion: The use of acitretin in combination with other psoriasis treatments, particularly topical corticosteroids and calcipotriene, is a common practice. Acitretin is co-prescribed with the biologics, likely because of the relative lack of overlapping effects on immune function. The immune-sparing method of action of acitretin makes combination treatment with the systemic agents an attractive treatment option, especially in patients where further immunosuppression is unwarranted.

Objective: To review the literature on the safety of tumescent liposuction, liposuction under general anesthesia and laser-assisted liposuction.
Results: Aggregate safety data on liposuction under tumescent anesthesia reveals over 100,000 body areas treated with liposuction. There were no serious complications of death, emboli, hypovolemic shock, perforation of thorax or peritoneum, thrombophlebitis, seizures, or toxic reactions to drugs. In contrast, in the plastic surgery literature, liposuction under general anesthesia was associated with complications of deep venous thrombosis or pulmonary embolus, abdominal or other organ perforation, infection, and bleeding. Most recently, survey data in the European literature analyzed data showed 72 cases of severe complications from liposuction, including 23 deaths in a 5-year period from 1998 to 2002. The most frequent complications were bacterial infections such as necrotizing fasciitis, gas gangrene, and different forms of sepsis. Further causes of lethal outcome were hemorrhages, perforation of abdominal viscera, and pulmonary embolism.
Conclusion: Tumescent local anesthesia utilizing lidocaine with epinephrine allows the removal of large volumes of fat with minimal associated blood loss and postoperative morbidity.

MATERIALS/METHODS: With approval from the institutional review board at the University of California, Irvine, an electronic survey was sent to practicing dermatologists that contained 18 questions regarding the approach to evaluating and treating hyperpigmentation under the eyes, in the axilla, and along the neck.
RESULTS: Fifty dermatologists completed the survey, and 46 (92%) reported treating patients with darker skin. The ethnic groups treated were Latino (97.8%), African American (97.8%), Middle Eastern (77.6%), and Asian (88.9%). Thirty-six reported treating patients with hyperpigmentation under the eyes, and 22 (61.1%) thought the hyperpigmentation was a result of idiopathic increase in melanin deposition. Forty-two responded to treating hyperpigmentation in the axilla, most of whom thought it was related to acanthosis nigricans (69.0%) or contact dermatitis (59.5%). Forty responded to treating hyperpigmentation on the neck, most of whom treated the condition with hydroquinone (66%). Treatments for these 3 areas were not found to be effective.
CONCLUSIONS: Hyperpigmentation under the eyes, under the arms, or on the neck is a significant problem in darker-skinned patients that is refractory to currently available treatments, highlighting the necessity of developing treatment approaches directed toward this population. Two cases of hyperpigmentation on the neck are presented, describing a new entity that primarily affects dark-skinned individuals.

OBJECTIVE: To determine and analyze what courses of treatment and in what frequency are being utilized to combat psoriasis in the United States.
METHODS: Analysis of data from the National Ambulatory Medical Care Survey (NAMCS) and National Hospital Ambulatory Medical Care Survey (NHAMCS) of the National Center for Health Statistics. Data were analyzed to examine the prevalence of different therapy techniques to combat psoriasis from 1993 through 2010. The trends for phototherapy, methotrexate (MTX), retinoids, cyclosporine A (CSA), systemic steroids, and biologics were all analyzed over the entire 18-year period and independently before and after the introduction of biologics in 2002.
RESULTS: From 1993 to 2010, the trend for total systemic treatments has not significantly increased (P=0.5). Frequency of phototherapy treatments significantly decreased from 1993 to 2010 (P<0.001). Since the introduction of biologics in 2002, their frequency has significantly increased, becoming the most frequently used treatment from 2008-2010 (P<0.0001).
LIMITATIONS: Severity of psoriasis was not recorded in the NAMCS and NHAMCS.
CONCLUSIONS: The frequency of systemic treatments to treat psoriasis has not significantly increased from 1993 to 2010. Despite the introduction of biologics, it appears that little progress has been made in reducing under-treatment of moderate-to-severe psoriasis.

Female-pattern androgenetic alopecia is a very common disorder that has been associated with extreme psychological morbidity. Few treatments have documented utility and many physicians are often overwhelmed with how little is pharmacologically available to treat this condition. Novel treatments that are effective, safe, less costly and simple are in high demand. We report a case of female-pattern androgenetic alopecia that failed to respond to a novel treatment with injected bimatoprost solution. Hypothetically, the treatment should have been effective and although we did not have success, this report suggests critical points to consider in the future of prostaglandin analogs, as well as other therapies being considered for the treatment of female-pattern hair loss.

Objective: The authors report a case of a female patient with psoriasis with severe cutaneous disease and extensive facial involvement successfully treated with adalimumab. This 50-year-old Caucasian female had a history of cutaneous psoriasis since 1990 and psoriatic arthritis since 2005. The patient had associated pruritus and a family history (maternal). Systematic treatment with mycophenolate mofetil and acitretin proved unsuccessful. The patient also lost efﬁcacy after months of ultraviolet light B and topical psoralen plus ultraviolet light A phototherapy.
Results: In 2007, the patient was screened and initiated therapy with a monoclonal humanized tumor necrosis factor alpha inhibitor, adalimumab. She had severe facial and body involvement with a body surface area of 25%, a Psoriasis Area and Severity Index of 20.4 (PASI), and a head and neck psoriasis area and severity index (HNPASI) of 3.6. Photographic documentation was carried out with improvement noted as soon as 4 weeks with continuing signiﬁcant response thereafter. No adverse effects were noted. The patient’s quality of life also improved.
Limitations: Although severe facial psoriasis is rare and associated with only the most extensive and severe psoriatic cases, it is likely the most psychologically disturbing and cosmetically disrupting to the patient because it cannot easily be covered or concealed. The authors hope this case can illustrate an excellent therapeutic option for these patients.
Conclusion: Although facial psoriasis is difﬁcult to treat, with newer systemic therapy now available in the form of biologics, patients now have a hope for this disease, especially devastating when associated with severe and extensive cutaneous involvement. The case gives promise in a serial photo-documented fashion of the success that can be achieved.

Non-invasive rejuvenation of the skin is performed regularly in many cosmetic offices. Using evidence-based medicine, we will review the various technologies being used for non-invasive rejuvenation. This includes the use of intense pulsed light (IPL), which has been thoroughly studied and shown to be quite useful for this type of rejuvenation in removing the red and brown pigments, as well as affecting collagen. Fractional lasers, both non-ablative and ablative in nature, also can show dramatic improvements in the skin and associated clinical studies are reviewed here. Also described are radiofrequency (RF) fractional pin devices and RF microneedles used for non-invasive rejuvenation. Picosecond lasers are showing very positive results in the non-invasive rejuvenation market. Finally, absorbable sutures are being used to lift the skin and add volume in the skin over a duration of time. They are quickly becoming more popular.

Five-Year Retrospective Review of Safety, Injected Volumes, and Longevity of the Hyaluronic Acid Belotero Basic for Facial Treatments in 317 Patients
Objective: The objective of this article is to report on use of this HA in a German clinic, over a period of 5+ years, in 317 patients (668 treatments).
Methods and Materials: Authors retrospectively examined patient charts of 317 patients (312 females), aged 24 to 87 years. Chart review showed areas treated, range of volumes per area, and mean volumes. Patient satisfaction data was collected anecdotally over the five years.
Results: Volumes of the HA injected ranged from 0.2 mL to 3.0 mL, depending on the area being treated. No serious adverse events were noted in the chart review, nor was any Tyndall effect observed in the treated areas. Anecdotal information suggests high patient satisfaction with results, based on the return of these patients to the clinic for other treatments over the more than five years.
Conclusion: Belotero Basic provides aesthetically pleasing results for treatment of facial defects, without carrying a risk of serious adverse events. North American physicians now have a new HA to consider as part of their treatment protocols.

Treating Photodamage of the Décolletage Area With a Novel Copper Zinc MalonateComplex Plus Hydroquinone and Tretinoin
James J. Leyden MD and Lisa Parr PharmD| |
Treatment was associated with early and significant (P≤0.05) improvements in mean scores on an overall integrated assessment of photodamage (from week 4 onward) and for multiple signs of photodamage—tactile roughness (from week 2 onward); mottled hyperpigmentation, lentigines and fine wrinkling (from week 4 onward); laxity (from week 8 onward); and crepiness and coarse wrinkling (from week 12 onward). Treatment was generally well tolerated and 94% of subjects were satisfied or very satisfied with the overall improvement in their décolletage at week 24.
Assessing Improvement of Facial Appearance and Quality of Life after Minimally-Invasive Cosmetic Dermatology Procedures Using the FACE-Q Scales
Brian P. Hibler BS, Jonathan Schwitzer MD, and Anthony M. Rossi MD| |
OBJECTIVE: We sought to determine the impact of laser resurfacing and injectable treatment (neurotoxin or fillers) on patient perceived improvement in facial appearance.
METHODS and MATERIALS: Patients were asked to complete FACE-Q scales (Satisfaction with Facial Appearance, Satisfaction with Facial Skin, and Appraisal of Facial Lines) at their pre-procedure consultation and/or at post-procedural follow-up. Item means (range 1-4) and Rasch transformed scores (range 0-100) were compared pre to post-procedure using two sample t-tests. Higher FACE-Q scores indicated greater satisfaction.
RESULTS: Overall, patients experienced a statistically significant improvement in all three scales pre- to post-procedure (P <0.05). Sub-group analysis showed statistically significant improvement in Satisfaction with Facial Appearance and Satisfaction with Facial Skin for both the laser resurfacing group and injectables group with moderate effect sizes. Improvement on Appraisal of Facial Lines trended toward improvement but did not reach statistical significance.
CONCLUSION: Our results support the ability to directly measure and quantify meaningful improvement in appearance among facial cosmetic dermatology patients using FACE-Q scales. Reporting this data is important, as this is the first step towards evidence-based cosmetic procedures in dermatology.

Background:Over the past 10 years, radiofrequency (RF) technology has been utilized for nonablative treatments for the treatment of
rhytides and skin laxity. This manuscript reviews the scientific background of collagen synthesis in vivo and in response to RF energy as
well as a clinical study of 17 patients receiving a series of facial treatments with a 4-MHz monopolar RF (Pellevé,Ellman International,
Inc, Oceanside, NY). Clinical methods, results, and a review of the literature for RF aesthetic treatments of the face are presented.
Methods:Seventeen patients were treated in one site with 6 total treatments scheduled as follows:1 session was performed every 15 days for 2 consecutive sessions, 1 session every month for 2 consecutive sessions, and 1 session every 2 months for 2 consecutive sessions. Both the treating physician and the patients via live viewing and comparison with baseline photographs performed assessment of results. Results are reported as averages across the 17 patients.
Results: Two weeks after the first treatment,patients noted an overall average of 25% to 30% improvement. Just before the last or sixth treatment, there was an average of 50% improvement noted by the physician, with patients ranking an average self-improvement of 48%. The treating physician rated average improvement of 46% compared with baseline,whereas the patients ranked average improvement of 30% compared with baseline at 1 year after treatment was initiated (6 months after the final treatment).Patients find this treatment to be very well tolerated, with minimal to no discomfort and no downtime or significant side effects.
Conclusions: The Pellevé 4-MHz monopolar RF device is effective, safe, and very well tolerated for treating laxity, texture, and wrinkles of the skin without complication or discomfort. Evidence in the literature supports the scientific mechanism of action of acute collagen modification and continued neocollagenesis observed with the system. In this cohort, patients maintain approximately 50% improvement on average at 6 months and a 30% to 50% improvement 1 year after beginning the treatments, 6 months after completion.

BACKGROUND: The number of nonsurgical aesthetic procedures performed in men is growing rapidly. However, there are limited data on treatment principles and goals for the male aesthetic patient.
OBJECTIVE: To review the objective data available on male aging and aesthetics and to synthesize with expert opinion on treatment considerations specific to male patients.
METHODS: Expert advisors met to discuss anatomical differences in male versus female facial anatomy related to aging, facial treatment preferences in aesthetically oriented men, and current dosing data for facial injectable treatments in male versus female patients.
RESULTS: Symmetry, averageness, sexual dimorphism, and youthfulness are generally accepted as factors that contribute to the perception of attractiveness. There are differences between men and women in facial anatomy, concepts of attractiveness in the context of masculinity and femininity, and treatment objectives. A communication gap exists for men, as evidenced by the lack of information available online or by word of mouth about injectable treatments.
CONCLUSIONS: Approaches to aesthetic consultation and treatment should differ between men and women based on the fundamental dissimilarities between the sexes. Educating men about available aesthetic treatments and about the safety and side effects associated with each treatment, as well as addressing concerns about their treatment results looking natural, are key considerations.

Introduction:Melasma is a common pigmentary disorder caused by abnormal melanin deposits within the skin. Hydroquinone (HQ)
is presently the most popular depigmenting agent, however the treatment of melasma remains unsatisfactory, resulting in a need
to evaluate new depigmenting agents.
Objective: The objective of this study was to assess, using standard methods and a novel technique, in vivo Reflectance Confocal Microscopy (RCM), the efficacy and safety of a new non-HQ bleaching agent Dermamelan® (Mesoestetic, Barcelona, Spain) in the treatment of melasma.
Methods: Ten women with melasma were enrolled in an open-label trial lasting four months. Patients were of Fitzpatrick skin types II–IV. A non-HQ depigmenting agent (Dermamelan) was applied once-daily for three months. Melasma Area and Severity Indices (MASI) were measured. Standard and UV-light photographs were taken and in vivo RCM, which detects pigmentary changes at a cellular level, was done. Evaluations were performed before treatment, on the first, second and third month of treatment and one month after treatment. Upon cessation of the trial, patients completed a questionnaire regarding efficacy and tolerance.
Results: At baseline, RCM detected hyperpigmented keratinocytes in all patients, dendritic cells in 2/10 patients, and melanophages in 2/10 patients. Based on the MASI score, Dermamelan treatment improved melasma by 50 percent. This was confirmed by standard and UV-light photography. Maximum therapeutic effect was usually reached by one month of treatment and was maintained at one month following its completion. Interestingly Dermamelan treatment also induced a statistically significant decrease of pigmented epidermal keratinocytes as detected by RCM. Patients with melanophages on RCM at baseline had a poorer outcome, but not those with dendritic cells. Mild irritation was the only adverse event observed during treatment. The majority of patients were satisfied with the result.
Conclusion: This study suggests that Dermamelan produces significant rapid improvement of melasma at a clinical and cellular level and demonstrates the potential of RCM to monitor and possibly predict efficacy of a new depigmenting agent in the treatment of melasma.

Hair loss is a complicated problem that causes significant concern for those who are affected. Patients seeking medical treatment have limited options that include topical minoxidil and oral finasteride. While these treatments are backed by long term clinical use and research outcomes, many patients find topical minoxidil difficult to incorporate into their daily routine and some are concerned with the side effects associated with finasteride. In the office setting, patients may be treated with more invasive procedures such as platelet-rich plasma injections (PRP) and hair transplantation, treatments that often must be repeated and can lead to a costly investment. Consumers are increasingly interested in natural treatments for hair loss. Many turn to basic supplements only to be disappointed when they fail to deliver due to lack of standardization and efficacy. In this paper we review the benefits of a nutraceutical containing a specific blend of highly purified, standardized, bio-optimized, and bioavailable botanical extracts to treat hair loss. These phytoactives were selected because of their diverse multi-modal biologic activity against inflammation, DHT, stress mediators, oxidative damage, and intermediary signaling cascades. This supplement represents a paradigm shift as it addresses not only the factors that trigger hair loss but the downstream mediators of inflammation as well. Multi-center clinical studies are currently underway to confirm the efficacy and benefits of this unique nutraceutical.

AIM: we report our experience comparing conventional PDT (406 patients) with daylight-mediated PDT (D-PDT) 240 patients with multiple actinic keratoses (AK), afferent to our photodynamic outpatients clinic from September 2013 to June 2014.
MATERIALS AND METHODS: to establish predictors for the clinical response to conventional PDT and daylight PDT (DPDT), a retrospective study on 646 patients was performed. The following parameters have been evaluated: sex, age, anatomic site of the primary tumor and local skin reactions. We used the Spearmen’s coefficient between the clinical response and the predictors analyzed; while Odds Ratio (OR) was performed to evaluate general clinical response and local skin reaction between PDT and D-PDT patients. Subsequently, we performed a sub-analysis, focusing to the anatomical sites, and we subdivided anatomical sites in face and scalp, nose, trunk, and extremities.
RESULTS: a total of 406 patients treated with PDT and 240 patients treated with D-PDT, were enrolled in the current report. The median age was 71 years in PDT and 73 years in D-PDT. The mean clinical response in PDT was of 74.4% and 95% in D-PDT. Performing OR between PDT and D-PDT, according to the clinical response, we found a better behavior in patients treated with D-PDT (P < 0.03); the same significance was maintained according to the presence or absence of local skin reaction (P < 0.0002). Using no parametric Spearman’s Coefficient test among predictive factors and the therapeutical response we found that D-PDT showed a better clinical response in patients with AK size ≥0.6 mm (P < 0.03), while this evidence was not present in PDT. The nose remained in both PDT and DPDT the main anatomical site with a better clinical response to the treatment.
CONCLUSION: Since efficacy of D-PDT is comparable or superior to conventional type, but is simpler and better appreciated by patients, in our opinion it may be used routinely to treat sun exposed multiple AKs especially in sun damaged skin also for aesthetic purposes.

BACKGROUND: Treatment of vitiligo is aimed at repigmentation and often consists of multiple modalities, none of which are universally or rapidly successful. Extensive cases are most often treated with ultraviolet light therapy, which can be both costly and time-consuming. Though vitiligo is an autoimmune disease, there is no current data to support systemic immunosuppressive monotherapy.
CASE SUMMARY: Here we present a case series of 3 patients with vitiligo treated for 11-16 months with low-dose methotrexate (12.5-25 mg per week) with folic acid supplementation with clinically significant skin repigmentation, with response within 6 months in one case. There were no severe adverse effects reported.
CONCLUSION: These cases demonstrate an unexplored effective and steroid-sparing therapeutic alternative in patients with vitiligo for whom topical therapy has failed and phototherapy is cost-prohibitive or ineffective.

The Effects of a Daily Skincare Regimen on Maintaining the Benefits Obtained from Previous Chemical Resurfacing Treatments
Suzanne Bruce MD,a Wendy Roberts MD,b Craig Teller MD,c and Lora Colvan BSd| |
OBJECTIVES: To evaluate whether a daily skin care regimen used for 12 weeks could maintain the benefits achieved with AGE and MELA chemical resurfacing treatments.
METHODS: Subjects who completed participation in the AGE and MELA skin resurfacing clinical trial were recruited to participate in a continuation trial and used a daily regimen of MDRejuvena facial products for 12 weeks. No other facial products were permitted. Physicians assessed the severity of individual skin parameters at baseline and week 12 and provided global assessment. Subjects assessed improvement of individual skin parameters at week 12 and provided an overall assessment.
RESULTS: Thirteen subjects participated in the 12-week continuation trial. According to the physician’s global assessment, all subjects demonstrated some level of improvement at week 12 compared to baseline. Physician assessment showed a decrease in severity of all skin parameters assessed at week 12 compared to baseline. According to the subject overall assessment at week 12, 11 of 12 subjects noted some level of improvement, 1 subject saw no improvement, and 1 subject did not provide an overall assessment. Mild to moderate improvement was observed by subjects in all individual skin parameters assessed except for skin discoloration.
CONCLUSIONS: The results of the continuation study demonstrate that use of a daily skin care regimen, which include combination of 2 various strengths of MDRejuvena Rejuvaphyl® Rejuvenating Complex: low strength (LS) and high strength (HS), not only maintains but can enhance the beneficial effects of skin resurfacing treatments for at least 12 weeks.

OBJECTIVE: To assess the risk of adverse events of special interest (AEoSIs) with ustekinumab and other psoriasis treatments in a real-world setting using 2014 Psoriasis Longitudinal Assessment and Registry (PSOLAR) data. AEoSIs included malignancy (excluding nonmelanoma skin cancer), major adverse cardiovascular events (MACE), serious infection, and all-cause mortality.
METHODS: Cumulative rates of AEoSIs/100 patient-years (PY) are reported for ustekinumab, infliximab, other biologics (mostly adalimumab/etanercept), and non-biologics based on pre-specified analyses using attribution rules biased against ustekinumab. Risk factors for AEoSIs, including treatments, were determined using multivariate statistical analysis.
RESULTS: A total of 12,093 patients (40,388 PY) were enrolled in PSOLAR. Overall incidence rates were 0.68/100PY for malignancy, 0.33/100PY for MACE, 1.60/100PY for serious infection, and 0.46/100PY for mortality. Unadjusted rates of serious infection for infliximab (2.91/100PY) and other biologics (1.91/100PY) were numerically higher compared with ustekinumab (0.93/100PY). Exposure to the combined group of biologics other than ustekinumab was significantly associated with serious infection (hazard ratio=1.96, P<.001). None of the biologics was associated with increased risk of malignancy, MACE, or mortality.
LIMITATIONS: Observational data have inherent biases.
CONCLUSION: Analysis of 2014 PSOLAR data identified no increased risk of malignancy, MACE, serious infection, or mortality with ustekinumab.

OBJECTIVES: We evaluated differences in outcome measures and definition of success in acne trials; and their impact on FDA approval and indications for acne medications.
METHODS: Review of acne clinical trial literature, prescribing information and regulatory guidelines for currently approved acne medications in the United States.
RESULTS: Numerous IGA scales exist with variations in specific categorical definitions. There are also differences in definitions of global success. Outcome success may not be accurately translated into corresponding terminology for indications.
CONCLUSIONS: Variability in IGA scales and definitions of success confound comparison of trial results for acne treatments. Harmonization and standardization of these factors will facilitate meta-analytics and treatment selection in patient care. Outcome measure success has not consistently been incorporated into acne medication indications.

The immunomodulatory characteristics and topical application of imiquimod (IQ), a toll-like receptor 7 agonist, have lead to extensive off-label therapeutic trials. Off-label use is not uncommon in dermatology. However, clinicians must make informed decisions to ensure safe and effective implementation when standardized protocols are lacking. We present the highest level of clinical evidence for each off-label application of IQ, summarize management steps, treatment regimens, and results. We hope consolidation of this information will facilitate implementation of informed and evidence-based clinical decisions. Forty-six off-label applications were reported. Treatments were generally applied in the same manner, tailored to induce an inflammatory response and reduced with the development of adverse reactions. The efficacy of imiquimod ranged from promising to suboptimal compared to standard treatments and protocols. Clinicians who choose to use IQ off-label should have a firm understanding of the extent an application has been studied and how to manage adverse events.

OBJECTIVE: To examine how tolerability is assessed, tolerability ratings, and clinical significance of tolerability ratings of topical antimicrobials for acne.
METHODS: A literature search was performed using the terms “tolerability AND acne AND (benzoyl peroxide OR antimicrobial OR clindamycin OR erythromycin OR dapsone OR sulfur OR sulfacetamide).” Inclusion criteria were: 1) evaluation of tolerability, 2) use of an identified topical antimicrobial for acne treatment without combination retinoid use, 3) an original study, in English.
RESULTS: Thirty-four of 132 articles met the inclusion criteria. Tolerability was measured through subject and investigator assessment of specific tolerability parameters and by reporting of adverse events. Nearly all of the acne treatments were well tolerated. Treatment related study discontinuation rates were low and had little to no relation to the degree of tolerability measures.
LIMITATIONS: Patients may be more adherent in clinical trials than in clinical practice. Differences in the measure used to assess tolerability make comparisons difficult.
CONCLUSIONS: Topical antimicrobial acne therapy is generally well tolerated. Discontinuation rates are low under study conditions. Tolerability of topical antimicrobial therapy for acne may not have great clinical significance.

Patients with skin of color suffer from different cutaneous issues when compared with skin of light complexion, and therefore management of the former must be representative of these variations. The most common pigmentary complaints in patients with skin of color are post-inflammatory hyperpigmentation, melasma and sun-induced hyperpigmentation. Often, patients with darker skin will turn to naturally occurring ingredients over synthetic analogues both to satisfy cultural preferences and to limit potential adverse effects that have been tied to synthetics. Science-based natural products can offer an attractive adjunct to conventional therapies that treat melasma, post-inflammatory hyperpigmentaion, and other dyschromias. Increasing data on the biological effects and the efficacy of natural therapies support the use of these complementary therapies in treating hyperpigmentation.

Clinical Evaluation and Quantitative Analysis of Axillary Hyperhidrosis Treated With a Unique Targeted Laser Energy Delivery Method With 1-Year Follow Up
David Caplin MD FACSa and Jordan Austin BSb| |
METHODS: Fifteen subjects were recruited to an approved Institutional Review Board study. Outcome measures were comprised of clinical and quantitative evaluation of functional impairment. This included HDSS scale, physician and subject evaluation, and digital photography of before and after starch iodine tests utilizing image processing and analysis software. Subjects received a single treatment and were evaluated at 1 week and at 3, 6, and 12 months post treatment. Responders were defined as those that scored an HDSS score of 1 or 2 post-treatment. Those that were non-responsive at 6 months received a second treatment.
RESULTS: All patients responded to treatment with 72% reporting a two-point HDSS score improvement and 28% reporting a 1-point improvement at 1-year follow-up. The average HDSS score improvement was 1.9/3.0. Three of the 15 patients at 6 months received a second treatment. The HDSS average score for all patients remained statistically stable at 1-year follow-up.
CONCLUSIONS: Treatment of axillary hyperhidrosis with the 1440nm Nd:YAG-pulsed laser combined with a targeted fiber and temperature-sensing device provides a safe and minimally invasive approach to the treatment of axillary hyperhidrosis with minimal side effects and long-term efficacy.

DESIGN: Retrospective, cross-sectional
METHODS: All patient visits with a code for psoriasis (ICD-9 696.1) in the clinical practice of two dermatologists with a high percentage (over 70% of chief complaints) of psoriasis patients from Jan 1, 2008 to Jan 4, 2012 inclusive were included in this retrospective data analysis. Patients were excluded if the baseline Physician's Global Assessment (PGA) at start of treatment was unknown, or less than 3 (moderate). The practice is a comprehensive psoriasis care center in the Northeastern United States serving a metropolitan population of over 4 million people. Patients were divided by treatment type (biologic, conventional systemic or both) and history of previous treatments. Patients were evaluated by Body Surface Area (BSA), PGA, Simple-Measure for Assessing Psoriasis Activity (S-MAPA, calculated by BSA multiplied by PGA). Patients were evaluated at baseline, 8, 12, 16, and 24 weeks after start of treatment. Patients must have completed at least 8 weeks on a single treatment in order to be included.
RESULTS: 46 courses of biologics, 12 courses of conventional systemic therapies, and 18 courses of both together were identified with PGA 3 or greater at baseline. Baseline S-MAPA for biologics was 74, for non-biologic systemics was 62.25. At week 24, S-MAPA improved 70.2% over baseline in patients treated with biologics, patients treated with non-biologic systemics improved by only 40.4% (P<0.05). The average number of prior treatments for patients on biologics was 1.87 versus 1.25 for patients on conventional systemic therapies (P=0.169).
CONCLUSION: Biologics show superior results to conventional systemic therapies (70% improvement versus 40% improvement) for the treatment of patients with moderate to severe psoriasis, as measured by decrease in S-MAPA (PGA multiplied by BSA) at week 24. These results were observed despite the fact that patients on biologics had a greater baseline severity and had a greater number of previous treatments.

As one of the most powerful and versatile features of the human face, the eyebrow informs the perception of beauty and plays a critical role in sexual dimorphism, facial recognition, and non-verbal communication. Eyebrow hair also serves many important biologic functions, including sensory transmission and protection from the elements, as well as playing an important role in cosmesis and expression.
New technologies to tighten and resurface the skin, to grow the hair of the eyelashes and eyebrows, to smooth-en and lighten the skin, and to replace volume lost from this area have created opportunities for rejuvenation that were not possible until recently. These include prostaglandin analogues that not only increase the length and width of the eyelashes but also improve the length and girth of eyebrow hair. Use of topical bimatoprost daily resulted in an improvement of eyelashes in 78.1% of subjects after 16 weeks. Using it in conjunction with botulinum toxins, light sources, topical cosmeceuticals, and fillers such as hyaluronic acid has vastly improved physicians' ability to treat the periorbital region.

OBJECTIVE: To evaluate the safety and efficacy of full-face treatments with various total doses of abobotulinum toxin A (ABO).
METHODS: A total of 90 participants were enrolled. Subjects had at least two indications for BoNT-A treatments on each third of the face (upper, middle and lower). They were randomized into 3 groups, with pre-defined total dose range of ABO, varying from 120 to 250 U.
RESULTS: Most of the subjects were women (96.5%). The statistically significant improvement from baseline lasted for more than 24 weeks for glabellar lines, and more than 16 weeks for forehead wrinkles and crow's feet, all P<0.001, with no differences between groups. The most frequent adverse event (excessive perioral weakness) was related to high dose in the perioral area.
CONCLUSIONS: This is the first study to compare safety and efficacy of different doses of ABO administered to the entire face simultaneously. As long as the recommended doses are used, concomitant injections of ABO are safe and efficient, with no increase in adverse events.

METHODS & MATERIALS: Twelve females received eight weekly non-ablative treatments using a tripolar radiofrequency device on the anterior and posterior upper arms. Evaluations included body weight, photographs, and circumference measurements at baseline and each subsequent week throughout the 8-week time period. The subjects and the investigator completed evaluations of clinical improvement using a 5-point assessment scale.
RESULTS: A significant circumference reduction was achieved in each arm of all twelve patients. A mean reduction of 1.99 ± 0.94 cm (P=0.001) was observed between the initial and final measurements after the 8-week treatment period. At the 4-week follow up, the average circumferential reductions of the posterior and anterior upper arms were sustained. Patient evaluations indicated moderate to good improvement of size, tightness, and overall appearance. The procedure was well tolerated without pain.
CONCLUSION: Tripolar radiofrequency devices offer a safe and effective non-invasive technology with beneficial effects on the circumferential reduction and overall appearance of the posterior and anterior upper arms.

Dapsone Gel 5% in Combination With Adapalene Gel 0.1%, Benzoyl Peroxide Gel4% or Moisturizer for the Treatment of Acne Vulgaris: A 12-Week, Randomized,Double-Blind Study
Alan B. Fleischer Jr. MD, Alan Shalita MD, Lawrence F. Eichenfield MD, William Abramovits MD,Anne Lucky MD, Steven Garrett DDS, for the Dapsone Gel in Combination Treatment Study Group| |
Methods: This was a twelve-week, randomized, double-blind study. Patients aged 12 years and older (n=301) applied dapsone gel twice daily and were randomly assigned (1:1:1) to one of three additional treatments, applied once daily.
Results: By week 12, dapsone gel combined with any of the three additional treatments reduced the mean number of inflammatory lesions. However, the authors did not detect a significant difference in the reduction of inflammatory lesions when dapsone was used in combination with adapalene gel or with benzoyl peroxide gel compared to the dapsone plus moisturizer combination group (P=0.052 for both versus moisturizer combination). Patients treated with dapsone gel combined with adapalene showed a significantly better response in reduction in non-inflammatory and total acne lesion count than those who received the moisturizer combination. Local adverse reactions in all three treatment groups were minimal and generally mild in severity.
Conclusion: Dapsone gel in combination with adapalene gel or benzoyl peroxide gel is safe and well tolerated for the treatment of acne vulgaris.

INTRODUCTION: Looking at alternatives to standard injectables and devices for rejuvenation, typical indications for facial rejuvenation are poor skin quality, pigmentary changes, and the loss of shape. Looking for effective treatments for those indications in the aesthetic field, one can notice a kind of “retro”-trend: easy-to-perform, non- or minimally-invasive, low-investment-requiring procedures are regaining a lot of popularity. And, over time, those treatments are becoming well defined and far more specific.
OBJECTIVE: To discuss an indication-specific full-face concept for facial rejuvenation using alternatives to standard injectables and devices for rejuvenation. Materials and Methods: The strategy of this indication-specific full-face concept is based on a three-pillar-principle: regeneration, regulation, and reshaping. In parallel to this concept, major indications such as poor skin quality, pigmentary changes, and loss of shape and definition are discussed. To address those indications, therapeutic principles such as topicals (cosmeceuticals, magistral formulations), mesotherapy, needling, chemical peelings, injection lipolysis, and thread lifting will be demonstrated.
CONCLUSION: As an alternative to standard injectables and devices, an indication-specific approach for a concept of full-face rejuvenation is based on the three-pillar-principle of regeneration, regulation, and reshaping by easy-to-perform, non- or minimally-invasive procedures for rejuvenation.

Safety and Efficacy of a New Device Combining Radiofrequency and Low-Frequency Pulsed Electromagnetic Fields for the Treatment of Facial Rhytides
Methods: Thirty-one subjects with facial wrinkles and rhytides were entered into this study. Every subject received 10 treatments of the face with a device that combines 1 MHz radiofrequency with PEMF with a flux of 15 gauss. Patients rated the pain level immediately after the treatment by using a visual analog scale (VAS) for pain. Side effects were recorded at every visit. The study's efficacy end point was evaluated by 2 blinded physicians who rated the standardized pictures from baseline and 3-month follow-up using the Fitzpatrick Wrinkle and Elastosis Scale (FWES).
Results: No unexpected adverse side effects were detected or reported for the duration of the study. Both raters recognized improvements of at least 1 grade on the FWES in 30 of 31 subjects (97%). The score decreased from 5.2 before the first treatment to 3.6 at 3 months after the last treatment. Furthermore, all patients rated the treatment to be free of pain on the VAS pain scale.
Conclusion: The results of this study show that the combination of multipolar RF with PEMF is a safe, effective, and painless approach to treat facial rhytides and is suitable to answer the demands of patients for safe treatments without pain or downtime.

AIM: To determine the efficacy, safety and tolerability of 5% ALA PDT in the treatment of truncal acne in Asians.
METHODS: Patients with truncal acne were treated with 5%-ALA under occlusion for 3 hours. All were subsequently treated with a red light source at wavelength 630 nm and an irradiance of 38mW/cm2 giving a total dose of 37 J/cm2. The numbers of acne lesions were recorded at baseline and regular intervals after treatment together with any adverse effects.
RESULTS: Fifteen patients were recruited. Overall, there was a 64.2% reduction in the inflammatory lesions count and a 24.3% reduction in the non-inflammatory lesions count at the end of the 12 weeks follow-up. Both mean lesions counts were significantly lower than baseline at all follow-up time points with paired t tests (all P values <0.05). Pain was well tolerated among our patients.
CONCLUSION: A single treatment session of 5%-ALA PDT was effective for the treatment of truncal acne with little side effects and acceptable in our Asian patients.

PURPOSE: To determine the demographics of acitretin prescribing patterns as an assessment of acitretin use in women of child-bearing potential.
METHODS: We examined National Ambulatory Medical Care Survey (NAMCS) data from the years 1990-2009 to determine demographic data on patients who were prescribed etretinate or acitretin. We used age under 50 as a proxy for childbearing potential.
RESULTS: From 1996-2009, there were an estimated 29 million office visits for psoriasis. Females accounted for 14.3 million of these visits, and 6.5 million (45.6%) of them were under the age of 50. The NAMCS contained only one record of a female patient under the age of 50 being prescribed acitretin from 1996-2009, the years during which acitretin had been available in the United States. This corresponds to an estimated 2.3% of all psoriasis patients prescribed acitretin during this time (20,000 out of 890,000).
LIMITATIONS: The NAMCS estimates national trends based on a large nationwide database. While the use of acitretin in women under 50 is low, the precision of the estimate is limited by the small sample size provided by this database.
CONCLUSIONS: There are now many alternative treatments besides acitretin for women of childbearing potential with moderate to severe psoriasis. Acitretin is used at most infrequently in this population. In females of reproductive potential, acitretin should be reserved for non-pregnant patients who are unresponsive to other therapies or whose clinical condition contraindicates the use of other treatments.
J Drugs Dermatol. 2013;12(7):799-802.
Objectives: To determine the prescribing pattern of dermatologists and nondermatologists when treating impetigo and the demographics of the patients treated.
Methods: National Ambulatory Medical Care Survey data on office visits for impetigo were analyzed from 1997 to 2007. Patient demographics and the treatments for impetigo were recorded.
Results: During this 10-year period, dermatologists managed an estimated 274,815 impetigo visits and nondermatologists an estimated 3,722,462 visits. Both dermatologists and nondermatologists most frequently prescribed oral antibiotics to treat impetigo. Topical antibiotics were second most common, and a variety of combination treatments were used.
Conclusions: Oral antibiotics are the most common class of medications used to treat impetigo. There is an opportunity for physicians to take advantage of the equally efficacious topical antibiotics for treating impetigo. A shift towards topical antibiotics would likely decrease morbidity (resulting from adverse effects) associated with use of oral agents.

Treatment of Facial Actinic Keratoses With Aminolevulinic Acid Photodynamic Therapy (ALA-PDT) or Ingenol Mebutate 0.015% Gel With and Without Prior Treatment With ALA-PDT
Brian Berman MD PhD, Mark S. Nestor MD PhD, Jessica Newburger DO,
Huynhee Park DO, and Nicole Swenson DO
METHODS: Twenty-four healthy adult male and female subjects who had 4 to 8 clinically visible and discrete actinic keratoses on the face in a contiguous 25cm2 treatment area. Subjects were randomized into one of three treatment groups: 2 treatments with 5-aminolevulinic acid (ALA) and photodynamic therapy (PDT), 1 ALA-PDT treatment and 1 course of ingenol mebutate (ingenol mebutate) 0.015% gel daily for 3 consecutive days, or 1 course of ingenol mebutate gel alone. Actinic keratoses in the treatment field were counted at the baseline visit, and at the completion of the study (day 57 or day 71). At the site of application, local site reactions were graded at each visit.
RESULTS: Subjects in the two ALA-PDT treatment group had a 97.5% mean reduction (P<0.00001) from the number of baseline actinic keratosis; ALA-PDT plus ingenol mebutate gel group had an 86.7% mean reduction (P<0.00001); while subjects in the ingenol mebutate gel alone group had a 91.7% mean reduction from the number of baseline actinic keratoses. The peak composite LSR score was 4.625 for the ALA-PDT group, 10.375 for the ALA-PDT followed by ingenol mebutate gel group, and 12.625 for the ingenol mebutate gel alone group (P=0.0004 and 0.001, respectively).
CONCLUSION: ALA-PDT, ingenol mebutate gel, and a combination of the two treatment modalities are successful topical therapies for the reduction of actinic keratoses on the face. The group of subjects receiving 2 consecutive treatments with ALA-PDT, compared to treatment with ingenol mebutate gel alone or sequentially after one course of ALA-PDT had a significantly lower mean composite LSR score and a non-significant trend for greater efficacy.

Dyschromia is one of the primary complaints for patients with skin of color. Treatments need to achieve a balance between tolerability and efficacy to address existing hyperpigmentation without causing additional damage that could trigger post-inflammatory hyperpigmentation (PIH). An open-label, single-center study was conducted to assess the efficacy of a novel comprehensive pigmentation control serum (LYT2) combined with a series of three very superficial chemical peels (VP) in skin of color subjects. Seventeen female and male subjects aged 36 to 69 years with Fitzpatrick Skin Types III-VI and moderate to severe facial hyperpigmentation were enrolled in the 12-week clinical study. Subjects identified as Asian, Hispanic, African American, or Caucasian ethnicities. Subjects received a series of 3 VP treatments every 4 weeks. LYT2 was applied twice-daily in between VP treatments. Investigator assessments for overall hyperpigmentation, overall photodamage, and skin tone unevenness, as well as standardized digital photography and subject self-assessment questionnaires were conducted at all visits (baseline and weeks 4, 8, and 12). In vivo reflectance confocal microscopy (RCM) of a target lesion was conducted (in a subset of subjects) at baseline and week 12. Fourteen subjects completed the study. The treatment regimen provided statistically significant improvements in all efficacy parameters at weeks 8 and 12 (all P less than equal to 0.03, student’s t-test). Standardized digital photography and RCM images support the improvements in overall hyperpigmentation observed by the investigator. At the end of treatment, the regimen was highly rated by subjects with 100% of subjects (strongly agree/agree) that the combination “decreased the appearance of uneven skin tone and discolorations” and “reduced the appearance of sun damage.” In addition to this clinical study, independent case studies with this combination treatment regimen at a separate study site were also conducted with results that corroborate the formal clinical study findings. The comprehensive results from these studies suggest that the combination of a comprehensive pigmentation control serum with a series of 3 very superficial chemical peels may provide an effective treatment approach for hyperpigmentation in skin of color patients.
