Telemedicine

Telemedicine flourished among dermatology practices in the wake of COVID-19. But as the world tentatively reopens, questions about connectivity, regulations, and payment will have to be addressed before physicians decide what role virtual visits will play in their practices.

Rosacea

In treatments addressing muscular contraction, botulinum toxin inhibits nerves that innervate blood vessels from releasing acetylcholine, which triggers vasodilation. Its impact on the innate immune system suggests that botulinum toxin may also help reduce recalcitrant rosacea-related papules and pustules.

According to one expert at the 29th European Academy of Dermatology and Venereology Virtual Congress, trichoscopy (a dermoscopy-based diagnostic method) not only helps diagnose hair disorders and monitor treatment but also predicts treatment efficacy.

A recent study shows an association between finasteride use and psychological adverse events (AEs) including suicidality. Dermatologists should weigh benefits and risks carefully when considering finasteride for certain patients with hair loss, according to one expert.

Pandemic Lessons

Read how some experts are balancing both their own health as well as the health of their patients during the COVID-19 pandemic.

Genetic polymorphisms may increase psoriasis susceptibility, according to a study that found patients who have the G allele in the JAK1 gene have twice the risk of developing psoriasis, and for those with the JAK3 allele, the risk rises nearly 2-fold.

In a recent study, psoriasis drugs showed widely variable drug survival rates, owing to differences in safety, efficacy, patient satisfaction and other factors. However, concerns linger over potential to cause long-term cumulative organ toxicity.

Comorbidities, co-medication, organ impairment, functional deterioration and frailty make treatment plans challenging for older psoriasis patients. However, these patients should not be precluded but will require more extensive evaluation and assessment, according to a recent study.

Joel Schlessinger, M.D., and Adam Friedman, M.D., detail how they have adapted to teledermatology since the start of the COVID-19 pandemic.

close up of squamous cell carcinoma tumor

A recent study underscores the need for a consistent scale to grade risk levels of cutaneous squamous cell carcinoma (SCC), particularly poorly differentiated tumors, according to study authors who presented at the 2020 virtual American Society for Dermatologic Surgery (ASDS) meeting.
