This edition of Resident Spotlight features Michael McLeod's winning poster,“Predictive Factors for Severity of Scar Formation After Skin Cancer Surgeries ” from the

Orlando Dermatology Aesthetic & Clinical Conference (ODAC) Second Annual Advanced Resident Training & Education (ARTE) poster competition.


The primary objective of the study was to determine if certain factors such as age, race, skin type, smoking, alcohol consumption, or type of wound closure would predict the likelihood of outcome using the Vancouver Scar Scale (VSS) or Scar Severity Scale (SSS) measures. Designed as a prospective, observational cohort involving 56 patients undergoing surgeries for skin cancer at the Mohs/Laser unit at the University of Miami Hospitals and Clinics at the Sylvester Comprehensive Cancer Center. There were no statistically signifi cant correlations between the dependent variable, VSS, and the independent variables of age, gender, Fitzpatrick skin type, race, smoking status, alcohol consumption, radiation history, keloid history, wound area and wound depth (all P values greater than 0.05). There was one statistically signifi cant correlation between wound closure and SSS. An odds ratio was calculated for the type of wound closure and SSS. An odds ratio was calculated for the type of wound closure and SSS score to be 0.73.

“This poster provided insight into which patient types, surgical location and surgical methods are at greatest risk of scarring. The information is valuable to the dermatologic surgeon in making judgments on the best surgical approach and post-op wound care. ”

Mark Bechtel, MD
ODAC Judge, Poster Session

“This study was well planned out with relevant and practical results. The resultant information will assist surgeons in preparing closures and warning patients of anticipated surgical outcomes.”

Michael P. McLeod is currently pursuing an M.D. at the University of Miami Miller School of Medicine and carrying out a two-year research fellowship with Dr. Keyvan Nouri. He graduated from the University of Guelph in Canada with Honors in Biological Science. Next, he completed a Master's Degree in Biomedicine at Florida Atlantic University. During his fi rst two years of medical school, he co-discovered a new way to measure the toxic contaminant diethylene glycol in glycerin based cough syrup using total attenuated fourier transform infrared and near infrared spectroscopy. Most recently, he is continuing his work in spectroscopy by defi ning the light absorption characteristics of cutaneous tumors. In the future, he hopes to complete a residency training program in dermatology with fellowships in dermatopathology, Mohs micrographic surgery and laser medicine. He would like to become a physician scientist conducting clinical trials, basic science research and writing textbooks. He is the author of numerous reviews, book chapters and case reports, primarily in the fi eld of dermatology. Michael has also given back to the community, by assisting in designing a Sun Safety Project to raise awareness and prevent skin cancer at local area schools and homeless shelters, as well as by being a member of the Board of Directors for the annual Melanoma 5K in Miami, FL. Before medical school, he was an avid equestrian, winning two national championships.
