Development and Validation of Algorithms to Identify Individuals With Cutaneous Lupus From Healthcare Databases.

Background: There are no validated methods to identify individuals with cutaneous lupus erythematosus (CLE) from large databases including claims data and electronic health records, severely limiting the study of the epidemiology of this disease.

Objectives: To develop and validate accurate algorithms to identify individuals with CLE from healthcare records.

Methods: Twelve case-finding algorithms were developed based on the International Classification of Diseases (ICD)-10 diagnosis codes, provider specialty, and medication prescription data.

Erythema dyschromicum perstans-like eruptions induced by epidermal growth factor receptor inhibitors in patients with lung cancer.

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.

Antimalarials are not Effective as Pre-Exposure Prophylaxis for COVID-19: A Retrospective Matched Control Study.

The early phase of the COVID-19 pandemic prompted a repurposing of antiviral and immunomodulatory drugs as investigational therapeutics, including hydroxychloroquine and chloroquine. While antimalarials have been well-refuted as a treatment for COVID-19, data on these drugs' role in preventing SARS-CoV-2 infection as pre-exposure prophylaxis is more limited. We investigated the efficacy of antimalarial drugs as pre-exposure SARS-CoV-2 prophylaxis in a US tertiary-care center.

Prevalence of inverse psoriasis subtype with immune checkpoint inhibitors.

Background: Cutaneous immune-related adverse events (irAEs) are the most common irAEs caused by immune-checkpoint inhibitors (ICI). Psoriasiform eruptions, both and flares, may occur. Evidence is lacking on inverse psoriasis subtype.

Primary cutaneous CD4 small/medium T-cell lymphoproliferative disorder in children: A case report and review of the literature.

Primary cutaneous CD4 small/medium T-cell lymphoproliferative disorder (PCSM-TCLPD) is a rare benign lymphoproliferative disorder, recently redefined by the 2016 World Health Organization classification of lymphoid neoplasms. In adults, PCSM-TCLPD responds well to monotherapy with surgical excision or local radiation, with or without topical/injected corticosteroids; in contrast, PCSM-TCLPD has only rarely been reported in children, in whom treatments favored in adults may be non-optimal. We present a 14-year-old male with PCSM-TCLPD on the forehead, who achieved complete remission following biopsy, topical corticosteroids, and surgical excision.

Outcomes of Acitretin Treatment for Refractory Multikinase Inhibitor-Induced Hand-Foot Skin Reaction.

This cohort study assesses the outcomes of acitretin treatment for multikinase inhibitor–associated hand-foot skin reaction.

Equity in medical education: Addressing microaggressions and discrimination on the wards.

Purpose: Existing frameworks to address instances of microaggressions and discrimination in the clinical environment have largely been developed for faculty and resident physicians, creating a lack of resources for medical students.

Methods: We implemented a workshop to prepare pre-clinical medical/dental students to recognize and respond to microaggressions. Participants in three cohorts from 2018 to 2020 completed pre- and post-workshop surveys assessing the prevalence of exposure to clinical microaggressions and the workshop's effect on mitigating commonly perceived barriers to addressing microaggressions.

Medical student perceptions of assessment systems, subjectivity, and variability on introductory dermatology clerkships.

Background: Elective introductory clerkships in dermatology serve a critical function in providing formative experiences to medical students interested in the field. Although dermatology clerkships play a pivotal role in students' career choices and residency preparation, the assessment systems used to evaluate students on these clerkships are widely different and likely affect student experiences.

Objective: This study aimed to explore the relationship between dermatology clerkship assessment systems and student experiences through interviews with students about their clerkship reflections and perceptions of assessment.

Impact of a case-based collaborative learning curriculum on knowledge and learning preferences of dermatology residents.

Objective: Case-based collaborative learning (CBCL) models that incorporate learner-guided content review, structured preparatory assessment, and interactive case-based classroom sessions have been shown to promote content mastery among medical students. However, limited research has explored the viability of CBCL in resident populations, particularly in dermatology. We therefore sought to investigate the impact of a CBCL curriculum covering complex medical dermatology topics on resident knowledge and learning preferences.
