This week’s episode features highlights of the AAD 2019 Summer Meeting.  Adam Friedman, MD, takes a closer look at nanotechnology from a dermatology perspective. Topical therapies often “have a very hard time getting to where they need to be, and nanotechnology, just by size alone, can really offer some unique benefits,” says Dr. Friedman, professor of dermatology and the interim chair of the dermatology department at George Washington University, Washington. Justin Ko, MD, director and chief of medical dermatology, Stanford (Calif.) Health Care, spoke with MDedge reporter Ted Bosworth about the use of augmented intelligence in dermatology. Dr. Ko is the coauthor of the American Academy of Dermatology’s position statement on augmented intelligence, which was released in May 2019. Henry W. Lim, MD, Henry Ford Hospital, Detroit, spoke with MDedge reporter Kari Oakes about potential environmental effects of sunscreen ingredients (particularly coral reef bleaching), as well as the FDA’s widely reported sunscreen absorption study published in May – and whether sunscreen use may be contributing to the increase in frontal fibrosing alopecia. Andrew Alexis, MD, professor and chair of the department of dermatology, Mount Sinai St. Luke’s, New York, provided practical information on treating hyperpigmentation in an interview with MDedge reporter Ted Bosworth. He details his views on the length of time he considers the use of hydroquinone-based therapies to be safe, as well as the use of non–hydroquinone based. Seemal R. Desai, MD, who is on the faculty at the University of Texas Southwestern Medical Center, Dallas, talked with MDedge editor Elizabeth Mechcatie about the treatment of patients with pigmentary disorders. The increasing interest in pigmentary disorders, particularly in patients with skin of color, “continues to be something that’s very relevant and very valid” to dermatologists, said Dr. Desai, who is the immediate past president of the Skin of Color Society. *  *  *   Help us make this podcast better!
