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.

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.

Large defects on the face after Mohs surgery have posed significant reconstructive challenges. A 90-year-old man presented with melanoma in situ of the central forehead, which resulted in a 4.5cmx4.3cm defect after multiple stages of Mohs surgery. Although different approaches for forehead repair with nasal root involvement are possible, we demonstrate that the V-Y advancement flap and subsequent Burrow graft for nasal root repair represents a viable closure technique for large circular defects of the central forehead.

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.

Fusion protein RUNX1-ETO (AML1-ETO, RUNX1-RUNX1T1) is expressed as the result of the 8q22;21q22 translocation [t(8;21)], which is one of the most common chromosomal abnormalities found in acute myeloid leukemia. RUNX1-ETO is thought to promote leukemia development through the aberrant regulation of RUNX1 (AML1) target genes. Repression of these genes occurs via the recruitment of the corepressors N-COR and SMRT due to their interaction with ETO. Mechanisms of RUNX1-ETO target gene upregulation remain less well understood. Here we show that RUNX1-ETO9a, the leukemogenic alternatively spliced transcript expressed from t(8;21), upregulates target gene Alox5, which is a gene critically required for the promotion of chronic myeloid leukemia development by BCR-ABL. Loss of Alox5 expression reduces activity of RUNX1-ETO9a, MLL-AF9 and PML-RARα in vitro. However, Alox5 is not essential for the induction of leukemia by RUNX1-ETO9a in vivo. Finally, we demonstrate that the upregulation of Alox5 by RUNX1-ETO9a occurs via the C₂H₂ zinc finger transcription factor KLF6, a protein required for early hematopoiesis and yolk sac development. Furthermore, KLF6 is specifically upregulated by RUNX1-ETO in human leukemia cells. This identifies KLF6 as a novel mediator of t(8;21) target gene regulation, providing a new mechanism for RUNX1-ETO transcriptional control.

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.
