PatientsLikeMe and Online Patient Support Communities in Dermatology.

Online patient-oriented platforms such as PatientsLikeMe (PLM) offer a venue for individuals with various diagnoses to share experiences and build community, though they may not be representative of the larger patient population. This potentially limits generalizability and raises concerns about the spread of misinformation, emphasizing the need for informed use and health care provider engagement.

This study underscores the persistent underrepresentation of women in academic dermatology leadership positions by examining the gender composition of editorial boards across top dermatology journals, emphasizing the urgent need for proactive strategies to promote diversity, equity, and inclusion.

Oral Cannabidiol for Seborrheic Dermatitis in Patients With Parkinson Disease: Randomized Clinical Trial.

BACKGROUND: Seborrheic dermatitis (SD) affects 18.6%-59% of persons with Parkinson disease (PD), and recent studies provide evidence that oral cannabidiol (CBD) therapy could reduce sebum production in addition to improving motor and psychiatric symptoms in PD. Therefore, oral CBD could be useful for improving symptoms of both commonly co-occurring conditions. OBJECTIVE: This study investigates whether oral CBD therapy is associated with a decrease in SD severity in PD. METHODS: Facial photographs were collected as a component of a randomized (1:1 CBD vs placebo), parallel, double-blind, placebo-controlled trial assessing the efficacy of a short-term 2.5 mg per kg per day oral sesame solution CBD-rich cannabis extract (formulated to 100 mg/mL CBD and 3.3 mg/mL THC) for reducing motor symptoms in PD. Participants took 1.25 mg per kg per day each morning for 4 ±1 days and then twice daily for 10 ±4 days. Reviewers analyzed the photographs independently and provided a severity ranking based on the Seborrheic Dermatitis Area and Severity Index (SEDASI) scale. Baseline demographic and disease characteristics, as well as posttreatment SEDASI averages and the presence of SD, were analyzed with 2-tailed t tests and Pearson χ2 tests. SEDASI was analyzed with longitudinal regression, and SD was analyzed with generalized estimating equations. RESULTS: A total of 27 participants received a placebo and 26 received CBD for 16 days. SD severity was low in both groups at baseline, and there was no treatment effect. The risk ratio for patients receiving CBD, post versus pre, was 0.69 (95% CI 0.41-1.18; P=.15), compared to 1.20 (95% CI 0.88-1.65; P=.26) for the patients receiving the placebo. The within-group pre-post change was not statistically significant for either group, but they differed from each other (P=.07) because there was an estimated improvement for the CBD group and an estimated worsening for the placebo group. CONCLUSIONS: This study does not provide solid evidence that oral CBD therapy reduces the presence of SD among patients with PD. While this study was sufficiently powered to detect the primary outcome (efficacy of CBD on PD motor symptoms), it was underpowered for the secondary outcomes of detecting changes in the presence and severity of SD. Multiple mechanisms exist through which CBD can exert beneficial effects on SD pathogenesis. Larger studies, including participants with increased disease severity and longer treatment periods, may better elucidate treatment effects and are needed to determine CBD's true efficacy for affecting SD severity.

Single-Cell RNA Sequencing Reveals Dysregulated POSTN+WNT5A+ Fibroblast Subclusters in Prurigo Nodularis.

Prurigo nodularis (PN) is an intensely pruritic, inflammatory skin disease with a poorly understood pathogenesis. We performed single-cell transcriptomic profiling of 28,695 lesional and nonlesional PN cells. Lesional PN has increased dysregulated fibroblasts (FBs) and myofibroblasts. FBs in lesional PN were shifted toward a cancer-associated FB-like phenotype, with POSTN+WNT5A+ cancer-associated FBs increased in PN and similarly so in squamous cell carcinoma. A multicenter cohort study revealed an increased risk of squamous cell carcinoma and cancer-associated FB-associated malignancies (breast and colorectal) in patients with PN. Systemic fibroproliferative diseases (renal sclerosis and idiopathic pulmonary fibrosis) were upregulated in patients with PN. Ligand-receptor analyses demonstrated an FB neuronal axis with FB-derived WNT5A and periostin interactions with neuronal receptors melanoma cell adhesion molecule and ITGAV. These findings identify a pathogenic and targetable POSTN+WNT5A+ FB subpopulation that may predispose cancer-associated FB-associated malignancies in patients with PN.

Tocilizumab Treatment in COVID-19 Patients: Comparing Cutaneous Disease and Adverse Drug Effects.

Actemra (tocilizumab) received emergency use authorization for the treatment of coronavirus disease 2019 (COVID-19) in June 2021. Literature has linked numerous cutaneous adverse effects to tocilizumab. In this current survey, investigators reviewed and compared these adverse effects to the common cutaneous manifestations of COVID-19. While similarities in patient presentation exist, important distinctions are made to aid dermatologists in their clinical diagnosis.  J Drugs Dermatol. 2023;22(12):e42-e43.     doi:10.36849/JDD.6532e.

Somatic mutations reveal hyperactive Notch signaling and racial disparities in prurigo nodularis.

Prurigo nodularis (PN) is a chronic inflammatory skin disease that disproportionately affects African Americans and is characterized by pruritic skin nodules of unknown etiology. Little is known about genetic alterations in PN pathogenesis, especially relating to somatic events which are often implicated in inflammatory conditions. We thus performed whole-exome sequencing on 54 lesional and nonlesional skin biopsies from 17 PN patients and 10 atopic dermatitis (AD) patients for comparison. Somatic mutational analysis revealed that PN lesional skin harbors pervasive somatic mutations in fibrotic, neurotropic, and cancer-associated genes. Nonsynonymous mutations were most frequent in NOTCH1 and the Notch signaling pathway, a regulator of cellular proliferation and tissue fibrosis, and NOTCH1 mutations were absent in AD. Somatic copy-number analysis, combined with expression data, showed that recurrently deleted and downregulated genes in PN lesional skin are associated with axonal guidance and extension. Follow-up immunofluorescence validation demonstrated increased NOTCH1 expression in PN lesional skin fibroblasts and increased Notch signaling in PN lesional dermis. Finally, multi-center data revealed a significantly increased risk of NOTCH1-associated diseases in PN patients. In characterizing the somatic landscape of PN, we uncover novel insights into its pathophysiology and identify a role for dysregulated Notch signaling in PN.

Cutaneous Manifestations of Anabolic-Androgenic Steroid Use in Bodybuilders and the Dermatologist's Role in Patient Care.

Young adults have been increasingly facing pressure to achieve an appealing athletic physique, often influenced by social media influencers on platforms like Instagram. This viewpoint highlights the association between image-centric social media, dissatisfied body image, the use of anabolic-androgenic steroids (AAS) to achieve desired results, and the overlooked dermatological side effects of AAS, including acne and acne fulminans. We underscore the importance of recognizing acne fulminans as an indicator of possible AAS abuse and encourage dermatologists to actively identify and address AAS use to improve their patients' well-being.

A Polygenic Risk Score for Predicting Racial and Genetic Susceptibility to Prurigo Nodularis.

Prurigo nodularis (PN) is an understudied inflammatory skin disease characterized by pruritic, hyperkeratotic nodules. Identifying the genetic factors underlying PN could help to better understand its etiology and guide the development of therapies. In this study, we developed a polygenic risk score that predicts a diagnosis of PN (OR = 1.41, P = 1.6 × 10-5) in two independent and continentally distinct populations. We also performed GWASs, which uncovered genetic variants associated with PN, including one near PLCB4 (rs6039266: OR = 3.15, P = 4.8 × 10-8) and others near TXNRD1 (rs34217906: OR = 1.71, P = 6.4 × 10-7; rs7134193: OR = 1.57, P = 1.1 × 10-6). Finally, we discovered that Black patients have over a two-times greater genetic risk of developing PN (OR = 2.63, P = 7.8 × 10-4). Combining the polygenic risk score and self-reported race together was significantly predictive of PN (OR = 1.32, P = 4.7 × 10-3). Strikingly, this association was more significant with race than after adjusting for genetic ancestry. Because race is a sociocultural construct and not a genetically bound category, our findings suggest that genetics, environmental influence, and social determinants of health likely affect the development of PN and may contribute to clinically observed racial disparities.

Prioritising Cochrane reviews to be updated with health equity focus.

BACKGROUND: The prioritisation of updating published systematic reviews of interventions is vital to prevent research waste and ensure relevance to stakeholders. The consideration of health equity in reviews is also important to ensure interventions will not exacerbate the existing inequities of the disadvantaged if universally implemented. This study aimed to pilot a priority setting exercise based on systematic reviews of interventions published in the Cochrane Library, to identify and prioritise reviews to be updated with a focus on health equity. METHODS: We conducted a priority setting exercise with a group of 13 international stakeholders. We identified Cochrane reviews of interventions that showed a reduction in mortality, had at least one Summary of Findings table and that focused on one of 42 conditions with a high global burden of disease from the 2019 WHO Global Burden of Disease report. This included 21 conditions used as indicators of success of the United Nations Universal Health Coverage in attaining the Sustainable Development Goals. Stakeholders prioritised reviews that were relevant to disadvantaged populations, or to characteristics of potential disadvantage within the general population. RESULTS: After searching for Cochrane reviews of interventions within 42 conditions, we identified 359 reviews that assessed mortality and included at least one Summary of Findings table. These pertained to 29 of the 42 conditions; 13 priority conditions had no reviews with the outcome mortality. Reducing the list to only reviews showing a clinically important reduction in mortality left 33 reviews. Stakeholders ranked these reviews in order of priority to be updated with a focus on health equity. CONCLUSIONS: This project developed and implemented a methodology to set priorities for updating systematic reviews spanning multiple health topics with a health equity focus. It prioritised reviews that reduce overall mortality, are relevant to disadvantaged populations, and focus on conditions with a high global burden of disease. This approach to the prioritisation of systematic reviews of interventions that reduce mortality provides a template that can be extended to reducing morbidity, and the combination of mortality and morbidity as represented in Disability-Adjusted Life Years and Quality-Adjusted Life Years.

Skin phototype of participants in laser and light treatments of cosmetic dermatologic conditions: A systematic review.

BACKGROUND: In cosmetic dermatology, lasers and lights treat a variety of hair and skin conditions, including some that disproportionately affect people of color. AIMS: Our systematic review aims to understand the representation of participants with skin phototypes 4-6 in cosmetic dermatologic trials studying laser and light devices. METHODS: A systematic literature search was conducted using search terms "laser," "light," and multiple laser and light subtypes in the PubMed and Web of Science databases. All randomized controlled trials (RCTs) published between January 1, 2010 and October 14, 2021 that studied laser or light devices for cosmetic dermatologic conditions were eligible for inclusion. RESULTS: Our systematic review included 461 RCTs representing 14 763 participants. Of 345 studies that reported skin phototype, 81.7% (n = 282) included participants of skin phototypes 4-6, but only 27.5% (n = 95) included participants of skin phototypes 5 or 6. This trend of excluding darker skin phototypes persisted when results were stratified by condition, laser of study, study location, journal type, and funding source. CONCLUSIONS: Trials studying lasers and lights for the treatment of cosmetic dermatologic conditions need better representation of skin phototypes 5 and 6.

Trends in pediatric non-operating room anesthesia: Data from the National Anesthesia Clinical Outcomes Registry.

BACKGROUND: Modern pediatric anesthetic encounters occur in operating rooms and non-operating room settings. Most anesthesia providers have cared for children in radiology, endoscopy, and other interventional settings at some point in their training and career. There is an absence of published data on the frequency, timing, and demographics of these pediatric anesthesia encounters. AIMS: The primary goal of our study is to present data spanning a variety of institutions and practice settings in the United States to define the percentage of non-operating room anesthetic encounters in children. We also set out to characterize the frequency of the most common procedures in the non-operating room setting within the United States. METHODS: Using the National Anesthesia Clinical Outcomes Registry data from 2015-2019, we analyzed and reported data on current trends in non-operating room anesthesia including patient demographics, encounter setting, procedure type, and the time at which anesthetic encounters occurred. RESULTS: 2 236 788 pediatric anesthetic encounters (patient age <18 y.o.) were analyzed revealing that 22.7% of all pediatric anesthetics occur in non-operating room settings. Patients were more likely to have higher American Society of Anesthesiologists Physical Status classifications in the non-operating room anesthesia group. Gastroenterological suites are the most common setting reported for pediatric non-operating room anesthesia. CONCLUSIONS: Non-operating room anesthesia in the United States is a prominent segment of pediatric anesthetic practice. Pediatric patients encountered in the non-operating room setting have more comorbidities, though further studies are needed to characterize the implication of this finding.

Monkeypox Vaccination and Cutaneous Considerations for the Dermatologist.

Monkeypox has infected over 18,000 individuals in the United States since the first reported case on May 17, 2022.1 Monkeypox is a variola poxvirus that is related to smallpox, but monkeypox symptoms (fever, painful vesicular or pustular rash, and lymphadenopathy) are milder and fatalities are rare.

Emojis and Emoticons in Health Care and Dermatology Communication: Narrative Review.

Background: Emoticons and emojis have become staple additions to modern-day communication. These graphical icons are now embedded in daily society through the various forms of popular social media and through users' personal electronic conversations. With ever-increasing use and inclusivity, exploration of the possible health care and dermatology applications of these tools is imperative. Objective: The goal of this narrative review was to provide and evaluate an up-to-date literature survey examining the utility of emoticons and emojis in medicine. Special attention was paid to their existing and potential uses in the field of dermatology, especially during the COVID-19 pandemic. Methods: A PubMed search of peer-reviewed publications was performed in mid-2021 to collect articles with emoticon or emoji keywords in combination with other health care-relevant or dermatology-relevant keywords. Screening of publications and described studies was performed by the authors with education and research experience in health care, dermatology, social media, and electronic communication trends. Selected articles were grouped based on common subjects for qualitative analysis and presentation for in-depth discussion. Results: From this extensive search, researchers were able to identify a wide variety of publications detailing the use of emoticons and emojis in general health care, pediatric health care, public health, and dermatology. Key subject areas that emerged from the investigation included the ability of emoticons and emojis to improve communication within pediatric health care, enhance mood and psychological assessment or mental health screening in adults, develop interventions to improve patient medication adherence, complement novel means of public health and COVID-19 surveillance, and bolster dermatology-specific applications. Conclusions: This review illuminated the repurposing of emojis and emoticons for a myriad of advantageous functions in health care and public health, with applications studied in many populations and situations. Dermatology-specific uses were relatively sparse in the literature, highlighting potential opportunities for growth in future studies and practices. The importance of diversity and inclusivity has extended to emojis, with the recent introduction of skin color customization and new emojis better representing the comprehensive spectrum of users' experiences. A continuously evolving and technology-driven population creates a unique niche for emoticons and emojis to ease worldwide communication and understanding, transcending the barriers of age, language, and background. We encourage future studies and innovations to better understand and expand their utility.

Analysis of Factors Contributing to Perioperative Mohs Micrographic Surgery Anxiety: Patient Survey Study at an Academic Center.

BACKGROUND: High perioperative patient anxiety is predictive of worse postoperative pain and quality of life. Several Mohs micrographic surgery (MMS) patient characteristics influence anxiety; however, the contributions of certain factors remain uncertain. OBJECTIVE: Investigate factors influencing perioperative MMS patient anxiety, especially those with debated impact or unclear data. METHODS: The authors surveyed 145 adult patients receiving MMS performed by a single MMS surgeon from 2018 to 2020. Patients self-reported demographics, history, and 10-point visual analog scale anxiety assessments at multiple stages. Health care provider (HCP)-perceived anxiety assessments were queried. A stepwise multiple regression modeling approach was used to explore potential factors. RESULTS: Younger age, female sex, and a self-reported history of anxiety confirmed by prior HCP diagnosis were significant predictors of pre-MMS anxiety. Postoperative anxiety increased with more layers removed and higher pre-MMS anxiety. HCP-perceived patient anxiety increased with younger patient age, more layers removed, prior skin cancer removal, and HCP-perceived pre-MMS patient anxiety. CONCLUSION: Anxiety-reducing interventions should target young female patients with a history of HCP-diagnosed anxiety, and patients with more layers removed. Prior skin cancer removal is associated with increased HCP-perceived intraoperative patient anxiety; however, it is not significant for patient-reported anxiety. Pre-MMS consultation may not be effective for anxiety reduction.
