Next Steps in Derm and the Journal of Drugs in Dermatology, in partnership with the Dermatology Education Foundation (DEF) and Physicians Resources,  interviewed Dr. April Armstrong (Professor of Dermatology and Associate Dean for Clinical Research at the Keck School of Medicine at USC) on applying the psoriasis guidelines established by the American Academy of Dermatology and the National Psoriasis Foundation to help guide the clinician community. As Dr. Armstrongs points out, one of the most important aspects of these guidelines is determining when systemic therapy is appropriate for psoriasis patients. Watch as Dr. Armstrong carefully explains the criteria needed to make this clinical decision as well as how she sees these guidelines evolving over time.
