Nirmatrelvir-ritonivir, COVID-19, and possible adverse cutaneous reactions.

Nirmatrelvir-ritonivir (Paxlovid) recently received emergency use authorization for the treatment of coronavirus disease 2019 (COVID-19). Literature has linked numerous cutaneous adverse effects to nirmatrelvir and ritonavir, the copackaged tablets within Paxlovid. A review and comparison of these adverse effects to the common cutaneous manifestations of COVID-19 is provided. Numerous drug-to-drug interactions exist between nirmatrelvir-ritonivir and commonly-used medications within dermatology.

Clinical and direct immunofluorescence characteristics of cutaneous toxicity associated with enfortumab vedotin.

Enfortumab vedotin (EV), a novel antibody-drug conjugate approved for metastatic urothelial carcinoma, causes a variety of cutaneous adverse reactions. We present two cases of bullous eruptions following treatment with EV, both demonstrating IgG deposition on direct immunofluorescence (DIF) correlating to the location of nectin-4 in the epidermis. This suggests that the IgG component of EV binding to nectin-4 in keratinocytes is likely a primary contributor to the high rates of cutaneous toxicity.

Sexual orientation and gender identity (SOGI) data in dermatologic studies and opportunities for inclusion.

Dermatologists serve a vast array of patients with unique backgrounds. The National Institutes of Health (NIH) designated members of sexual and gender minorities as underrepresented in scholarly literature. Our study examines the past 10 years of studies published in highly-cited dermatologic journals, surveying each study for common data collection of sexual orientation and gender identity (SOGI) in dermatological studies. We found representation of sexual and gender minorities to be increasing in dermatological studies but recommend that SOGI data be collected regularly just as any other common variable in dermatological patient studies.

A Review of the Current Evidence Connecting Seborrheic Dermatitis and Parkinson's Disease and the Potential Role of Oral Cannabinoids.

Parkinson's disease (PD) is a neurodegenerative disorder associated with multiple comorbidities, including seborrheic dermatitis (SD), which develops in more than half of PD patients. SD in patients with PD can be severe and frequently intractable by traditional topical therapy. Cannabinoids possess anti-inflammatory and neuromodulatory properties working within the intrinsic endocannabinoid system, the activation of which may alleviate the motor symptoms of PD. The effect of cannabinoids on SD is unknown. Here we explore the pathophysiological mechanisms and possible therapeutic role of oral cannabinoids in PD patients with SD, and review speculative mechanisms underlying the association of PD and SD. Current data supporting the use of cannabinoids in both PD and SD, as well as oral cannabinoid safety and tolerability, are presented. Cannabinoids may provide the possibility of simultaneous treatment of both SD and PD. Specific SD studies and additional safety data on oral cannabinoids are needed.

Response to "Assessing a Paradigm Shift: Perceptions of the USMLE Step 1 Scoring Change to Pass/Fail".

We commend Wei et al1 for highlighting the fundamental shift that dermatology program directors (PDs) and students alike will experience following the change of the USMLE Step 1 to pass/fail.

Hand hygiene during COVID-19: Recommendations from the American Contact Dermatitis Society.

The recent COVID-19 pandemic has resulted in increased hand hygiene and hand cleansing awareness. To prevent virus transmission, the Centers for Disease Control and Prevention recommends frequent hand washing with soap and water. Hand hygiene products are available in a variety of forms, and while each of these formulations may be effective against COVID-19, they may also alter skin barrier integrity and function. As health care workers and the general population focus on stringent hand hygiene, the American Contact Dermatitis Society anticipates an increase in both irritant contact and allergic contact hand dermatitis. Alcohol-based hand sanitizers with moisturizers have the least sensitizing and irritancy potential when compared to soaps and synthetic detergents. This article provides an overview of the most frequently used hand hygiene products and their associations with contact dermatitis as well as recommendations from the American Contact Dermatitis Society on how to treat and prevent further dermatitis.

An Analysis of Skin of Color Dermatology Related Content on Instagram.

Importance: Social media is making information about skin of color more readily available to those unfamiliar with ethnic skin and hair. Objectives: To answer: 1) what skin of color-related dermatology content is being posted on Instagram? And 2) who is producing this content? Design: Cross-sectional epidemiologic study analyzing the content of posts associated with 31 Instagram skin of color dermatology-related topics (hashtags). Setting: Population-based Participants: The Instagram accounts linked with the top 9 posts as generated by the Instagram algorithm associated with each search term. Exposures: Instagram account holders. Main Outcomes and Measures: [1] The number of posts associated with each skin of color dermatology hashtag search term. [2] Classification of posts as either educational or promotional. [3] Classification of posts as a photo or video. [4] Classification of Instagram accounts that produced the posts (American board-certified dermatologists, dermatology residents, foreign dermatologists, patients, medical interest groups, or other). [5] Quantification of the number of post likes and comments. [6] Comparison of number of educational and promotional posts between board-certified dermatologists and other Instagram users. Results: The 31 sampled hashtags were associated with a total of 9,087,589 posts as of January 16, 2020. 219 of the 288 top posts generated from these queries met inclusion criteria. Board-certified dermatologists (26 posts) only generated 12% of top posts, whereas individuals not certified in dermatology produced 88% of top content. Of this group, social media influencers were the largest subcategory (37 posts). A majority of the top posts were promotional (135 posts, 61.6%) and formatted as photos (181 posts, 82.6%). While there was a significant difference in the number of likes for content posted by board-certified dermatologists vs non-dermatologists (P=0.027), these differences became non-significant after stratifying by the intention of the post (promotional P=0.13, educational P=0.17). Conclusions and Relevance: Board-certified dermatologists are underrepresented among people generating top skin of color dermatology-related content on Instagram. Board-certified dermatologists should establish a more prominent presence on social media platforms so that patients have greater access to accurate, evidenced-based educational resources regarding dermatologic conditions, treatment options, and treatment risks from reliable sources.

An Observational Study of the Application of a Topical Cannabinoid Gel on Sensitive Dry Skin.

Atopic dermatitis (AD) is a chronic skin disorder characterized by pruritus, erythema and excoriation. While AD has a multifactorial etiology, neuro-signaling pathways are now recognized to play an essential role in the pathogenesis of AD, particularly pruritus. Neuromodulators, such as topical naltrexone, are being utilized in AD treatment. Another class of neuromodulator, Palmitoylethanolamide (PEA), has demonstrated effectiveness in the treatment of itch, excoriation and erythema in AD patients. Phytocannabinoids including cannabidiol (CBD) are becoming increasingly accessible to the public and continue to be advertised for their efficacy to treat inflammatory skin disorders such as eczema. However, no human studies have been conducted to support the claim. Therefore, this study aimed to explore the effects of CBD in individuals with self-reported eczema. Twenty individuals consented to participate and 16 completed a 28-item online questionnaire assessing subjects’ disease severity using Patient Oriented Eczema Measure (POEM) and psychosocial burden of their disease through the emotional domain of Quality of Life Hand Eczema Questionnaire (QOLHEQ). Findings demonstrated a significant reduction in the mean score of POEM from baseline (mean ±SE: 16±1.35) and at a two weeks interval (8.25 ±1.80), P<0.0007. Similar reduction was seen in emotional domain of QOLHEQ from a mean score of 20.9±2.06 to 8.375 ±1.609 at 2 week-interval, P<0.004. 67% of subjects reported a decrease in itch and 50% perceived an improvement in their eczema by more than 60%. This observational study shed light on the potential clinical utility of topical CBD in the treatment of atopic dermatitis. J Drugs Dermatol. 2020;19(12): doi:10.36849/JDD.2020.5464.

Orchestrating a virtual conference amidst the COVID-19 pandemic.

The current Coronavirus Disease 2019 (COVID-19) pandemic has impacted individuals and groups all across the globe as countries and cities face widespread lockdown to limit transmission of the virus. Many have adapted quickly, utilizing virtual platforms for interviews, employment, and academic/social events. Academic conferences, such as the annual Cochrane Skin Conference, faced similar challenges as large gatherings have been banned. The in-person conference was cancelled several days prior to its hosting at the University of Colorado, leading conference organizers to employ a virtual platform to continue the conference as scheduled. In this letter, logistics, troubleshooting, and conversion of an NIH-funded conference from an in-person to a successful virtual conference are discussed. We hope this letter may serve as a guide for future hosting of academic conferences, and to those dedicated to collaboration and the sharing of information during such unprecedented times.

Widening the scope of virtual reality and augmented reality in dermatology.

Virtual reality (VR) and augmented reality (AR) are making headlines, pushing the boundaries of educational experiences and applicability in a variety of fields. Medicine has seen a rapid growth of utilization of these devices for various educational and practical purposes. With respect to the field of dermatology, very few uses are discussed in the literature. We briefly present the current status of VR/AR with regard to this specialty.

Teledermatology application use in the COVID-19 era.

Owing to the COVID-19 outbreak, the use of telemedicine applications has increased throughout the United States. Using an algorithm to analyze mobile application rankings, we were able to examine how applications with telemedicine services have increased in prevalence and rank pre- and post- COVID-19. Telemedicine apps saw an increase of 210.92 ranked positions on average. Within US telehealth, skin conditions have become the fifth most common diagnosis. Widespread use of teledermatology has been well-accepted. Dermatologists and patients report high satisfaction using teledermatology during COVID-19 and intend to continue using these services in the future. COVID-19 has assisted in reducing physician concerns previously preventing some dermatologists from utilizing teledermatology in their services. Additionally, the geographical and socioeconomic barriers preventing some patients from receiving dermatologic care have been minimized through the use of teledermatology. Addressing these obstacles for dermatologic care improves healthcare equity.
