RESUMO
INTRODUCTION: Cutaneous adverse reactions to epidermal growth factor receptor inhibitors (EGFRi) are some of the most common side effects that patients experience. However, cutaneous adverse reactions that cause dyspigmentation in patients have been rarely reported. Erythema dyschromicum perstans (EDP) is a rare pigmentary condition that causes ashy-grey hyperpigmented macules and patches, with a few cases reported from EGFRi in the literature. The disfiguration caused by this condition may negatively impact patients' quality of life. Our study aimed to describe the clinical characteristics of EDP induced by EGFRi to better recognize and manage the condition. METHODS: We conducted a multicenter retrospective review at three academic institutions to identify patients with EDP induced by EGFRi from 2017 to 2023 and included sixteen patients in our study. RESULTS: The median age of patients was 66 years old, with 63% female and 37% male (Table 1). The majority of our patients were Asian (88%). All patients had non-small cell lung cancer and most patients received osimertinib. Median time to EDP was 6 months. The most common areas of distribution were the head/neck region, lower extremities, and upper extremities. Various topical ointments were trialed; however, approximately less than half had improvement in their disease and most patients had persistent EDP with no resolution. All patients desired treatment except one with EDP on the tongue, and there was no cancer treatment discontinuation or interruption due to EDP.

Clinicians should be able to recognize this condition in their patients and assess how it is affecting their quality of life, and refer to dermatology to help with management.

PURPOSE: Cutaneous reactions to BRAF inhibitors are common, but severe reactions resembling or consistent with drug-induced hypersensitivity syndrome (DIHS)/drug reaction with eosinophilia and systemic symptoms (DRESS) are relatively rare. Several reports suggest that cutaneous reactions including DRESS/DIHS to BRAF inhibitors are more frequent and severe in the setting of previous immune checkpoint inhibition (ICI). METHODS: To characterize existing literature on these reports, we queried the PubMed/MEDLINE database for cases of DIHS/DRESS to BRAF inhibitors. RESULTS: We identified 23 cases of DIHS to BRAF inhibitors following checkpoint inhibition and 14 cases without prior checkpoint inhibitor therapy. In both cohorts, DIHS occurred relatively early, with median time to onset from drug exposure of 8-10 days. Patients who received prior ICI were less likely to have peripheral eosinophilia (26% vs 71%), atypical lymphocytes (9% vs 50%), renal involvement (61% vs 79%), hepatic involvement (52% vs 86%), and lymphadenopathy (9% vs 43%) compared to patients who did not receive prior ICI. Thrombocytopenia was more common with prior ICI (17% vs 7%). Only patients who received prior ICI experienced hypotension (26%) during the course of their DIHS. All cases of BRAF-induced DIHS generally improved on systemic steroids/supportive care, and no cases of death were identified. CONCLUSION: Dermatologists should consider a diagnosis of DIHS following BRAF inhibitor initiation, particularly in the setting of past checkpoint inhibition, with atypical features including relatively rapid onset and steroid responsiveness, lack of peripheral eosinophilia, lymphocytosis, or lymphadenopathy, and increased risk of thrombocytopenia and hypotension.

BACKGROUND: "Student-as-Teacher" (SaT) programs have been growing in number to prepare medical students for their teaching roles in residency and beyond, but it remains unknown what content areas should be covered in SaT curricula. AIM: To determine five to ten "essential" content areas for inclusion in SaT curricula using expert opinion. METHODS: Using a three-round Delphi process, moderators iteratively surveyed a panel of 28 medical educators (25 academy directors and three individuals identified as having expertise in undergraduate medical education) representing 25 medical schools in the United States. This "SaT Delphi Working Group" was tasked with rating topics for inclusion in SaT curricula on a 3-point scale (i.e. 1. "essential," 2. "important, but not essential" 3. "not important"). Topics achieving ≥70% consensus as "essential," "important" or "not important" were accepted by the moderators and removed from subsequent rounds. RESULTS: Hundred per cent response rate (n = 28) was achieved for all survey rounds. Five content areas reached consensus as "essential" for inclusion in a SaT curriculum: feedback, bedside teaching and clinical precepting, small-group teaching, case-based teaching and professionalism as a medical educator. CONCLUSION: This consensus from a group of leaders in medical education is a first step toward the implementation of more developmentally-appropriate SaT competencies.

Increasingly over the past decade, faculty in medical and graduate schools have received requests from digital millennial learners for concise faculty-made educational videos. At our institution, over the past couple of years alone, several hundred educational videos have been created by faculty who teach in a flipped-classroom setting of the pre-clinical medical school curriculum. Despite the appeal and potential learning benefits of digital chalk-talk videos first popularized by Khan Academy, we have observed that the conceptual and technological barriers for creating chalk-talk videos can be high for faculty. To this end, this tips article offers an easy-to-follow 12-step conceptual framework to guide at-home production of chalk-talk educational videos.

Much has been written about the learning benefits of peer teaching for medical trainees. What remains less certain is how practically to implement "Student-as-teacher" (SaT) programs combining teacher-skills training with hands-on teaching experiences for medical students to prepare them for their roles as teachers in residency and beyond. In this article, we address this gap by outlining twelve tips for the implementation of SaT programs based on review of the literature and our experience implementing SaT curricula at our institution. We have organized the tips into three domains (i.e. preimplementation, implementation and postimplementation) to encourage SaT coordinators to iteratively consider how to continually enhance SaT programs before, during and after their implementation.

Dermatology residents perform consults on hospitalized patients, but are often limited in their ability to follow-up with these patients after discharge, leading to inadequate follow-up and understanding of post-discharge transitions of care. In 2013, a discharge continuity clinic (DCC) staffed by the inpatient consult dermatology resident and attending dermatologist was established at one of the four adult hospital sites residents rotate through in the Harvard Combined Dermatology Residency Program. Resident perceptions about the DCC and their educational experience on inpatient consult rotations with a DCC and without a DCC were obtained using a cross-sectional survey instrument in June 2016. Self-reported data from a multi-year cohort of dermatology residents (n = 14 of 20, 70% response rate) reveals that the DCC enabled resident autonomy and resident satisfaction in care of their patients,insight into the disease-related challenges and the broader social context during transitions of care from inpatient to outpatient settings, and more enriching learning experiences than inpatient consult rotations without a DCC. Dermatology residents self-report participation in an inpatient consult rotation with aDCC supports their autonomy and achievement of post-discharge transitions-of-care competencies.

In the current digital age, medical education has slowly evolved from the largely lecture-based teaching style of the past to incorporate more interactive pedagogical techniques, including use of social media. Already used readily by millennial trainees and clinicians, social media can also be used in innovative ways to teach trainees and facilitate continuing education among practicing clinicians. In this commentary, we discuss many learning benefits of social media and review potential pitfalls of employing social media in both trainee and physician dermatological education.

A 28-year-old man with clinically and laboratory diagnosed anti-PL-12 anti-synthetase syndrome (AS) in 2009 developed cutaneous lupus lesions, discoid lupus lesions, and sclerodacytly with finger-tip ulcerations four years following his AS diagnosis. Laboratory tests including +ANA, +anti-dsDNA antibody, +anti-Smith antibody, and +anti-RNP antibody in 2014 confirmed the diagnosis of progression to an overlap syndrome including systemic lupus erythematosus. The patient now also has clinical findings (sclerodacytly, Raynaud phenomenon, finger-tip ulcerations) consistent with scleroderma overlap. In each stage of his evolving connective tissue disease, cutaneous findings have been central to the recognition and monitoring of his overlap syndromes.

Many medical schools have integrated early clinical skills courses to ease the "pre-clinical" to "clinical" transition for medical students. However, it may also be beneficial for medical students to revisit the pre-clinical basic sciences after their core clerkship rotations to foster a deeper understanding of causal pathways of disease that often take a backseat to clinical management principles during the clerkship experience. To this point, the author reflects on the learning benefits she experienced at the end of medical school when she served as a near-peer teacher in an integrated, organ-based physiology and pathophysiology course for first-year medical students. "Teaching to learn" as a senior medical student may be a way to consolidate and foster deeper understanding of medical knowledge in the post-clerkship period of medical school.

Nutritional deficiency is rare in developed countries, but can be acquired from decreased nutrient intake, reduced absorption, and increased gastrointestinal excretion. We report a patient with acquired acrodermatitis enteropathica (AE) who exhibited low plasma zinc levels and concurrent nutritional deficiencies (pyridoxine, selenium and fatty acids). Our patient had undergone Roux-en-Y gastric bypass 13 years prior to presentation. The rash, consistent with AE clinically and histologically, nearly resolved one week after starting IV zinc supplementation, total parenteral nutrition, and micronutrient supplements. This case highlights the importance of long-term post-operative follow-up for gastric bypass patients who are at high risk for micronutrient and macronutrient deficiencies and illustrates the potential for rapid improvement with IV supplementation.

BACKGROUND: Elective visual arts-based courses for trainees in the health professions may, amongst other things, help improve visual diagnostic skills. An emphasis on the careful observation of visual art and medical images and the co-teaching of such courses by both medical faculty members and local art educators seem to be particularly important elements for the successful implementation of such courses. LITERATURE REVIEW: At least 12 studies to date suggest that guided observation of visual art (e.g. paintings and photography) can enhance the quality and/or quantity of visual observations. More research is needed regarding optimal course structure and assessment, but existing evidence supports the development of visual arts-based coursework for health care trainees using strategies such as 'visual thinking skills' and engagement and processing in groups. TAKE-HOME MESSAGE: The arts or 'medical humanities' are increasingly used in the education of health professionals, and growing evidence exists that visual arts-based coursework, in particular, can enhance the observation skills of participants. Notably, the expertise and experience of trainees in specific disciplines are likely to influence specific learning goals and course structure in each context; however, unique arts-based teaching strategies (e.g. 'visual thinking skills') can be used across all settings. There is no more difficult art to acquire than the art of observation William Osler, 19031.

Challenge: It takes practice and thoughtful planning to inspire trainees to actively process new information instead of passively receive it. In fact, research suggests "active teaching" does not always lead to "active learning," so what are some general principles to encourage trainees to engage in active learning in any teaching context?

Challenge: "Case-based teaching" is a buzzword for engaging clinical teaching through cases, but how can it be implemented effectively in practice? We review popular case-based teaching methods (i.e., one-minute preceptor, SNAPPS, and the "Aunt Minnie method") for use during traditional one-on-one clinical preceptorships in the ambulatory dermatological setting.

Challenge: The "flipped classroom" is a pedagogical model in which instructional materials are delivered to learners outside of class, reserving class time for application of new principles with peers and instructors. Active learning has forever been an elusive ideal in medical education, but the flipped class model is relatively new to medical education. What is the evidence for the "flipped classroom," and how can these techniques be applied to the teaching of dermatology to trainees at all stages of their medical careers?
