The diagnosis of scabies can be difficult when the infection presents as erythroderma. Crusted scabies is a severe form of scabies caused by cutaneous ectoparasitic infection by the mite Sarcoptes scabiei var hominis. Crusted scabies most commonly occurs in patients with underlying immunosuppression from acquired infection or subsequent to solid organ or bone marrow transplantation. We present a rare case of a patient with granulomatosis with polyangiitis (GPA) who developed azathioprine-induced myelosuppression and subsequent erythrodermic crusted scabies. It is critical to maintain a broad differential when patients present with erythroderma, especially in the setting of medication-induced immunosuppression for the treatment of autoimmune disease.

Minority patients are more likely to require dose adjustments for chemotherapy, with cultural barriers and access to medical care cited as contributory factors. Objective: We sought to pilot an educational intervention, in the form of a pamphlet, to evaluate the effectiveness of this tool in teaching skin of color (SoC) patients about potential dermatologic toxicities of chemotherapy that are relevant to their skin type. Methods: At a chemotherapy infusion center, SoC patients (n = 26) who were receiving chemotherapy for breast cancer voluntarily consented to read an educational pamphlet and complete a series of survey questions before and after this educational intervention. Results: Most participants identified as female (96%), African American/Black (81%), and non-Hispanic (85%); all respondents had obtained at least a high school degree. Survey responses revealed a significant increase in knowledge about the potential dermatologic effects of cancer treatment after this intervention. Notably, 100% of participants either agreed or strongly agreed that they would like to see other doctors use this educational tool as a form of patient education, that they would recommend this pamphlet to other patients who are starting cancer treatment, and that the pamphlet was easy to understand. Limitations: Limitations of this study include small sample size and single-institution recruitment, which may limit generalizability. Furthermore, this study only included patients who are proficient in English. Conclusion: This study pilots an effective educational tool that addresses dermatologic toxicities of chemotherapy that are relevant to SoC patients. Further multi-institutional studies with larger sample sizes and translation to other languages can overcome the limitations of this pilot study.

Tyrosine kinase inhibitors (TKIs) have emerged as a new frontier of cancer therapy. These agents include inhibitors of epidermal growth factor receptor (EGFR), human epidermal growth factor receptor 2 (HER2), BRAF, mitogen­activated protein kinase kinase (also referred to as MEK), bcr­abl, c­KIT, platelet­derived growth factor (PDGFR), fibroblast growth factor receptor (FGFR), anaplastic lymphoma kinase (ALK) and vascular endothelial growth factor (VEGF). Along with the evolving applications of TKIs, there has been an increased recognition of the breadth of potential cutaneous toxicities to these agents. In this review, we provide an overview of potentially life­threatening severe cutaneous adverse reactions (SCARs) that may occur during therapy with TKIs. These toxicities include Stevens­Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP).

Segmental vitiligo often presents in childhood and tends to be more recalcitrant to therapy than generalized vitiligo. Recently, Janus kinase inhibitors have emerged as a promising treatment option, with some reports suggesting that concomitant ultraviolet light exposure may enhance therapeutic response. Here, we present a child with segmental vitiligo who responded rapidly and completely to treatment with tofacitinib cream plus phototherapy.

Immune checkpoint inhibitors (ICPi) have emerged as a new frontier of cancer therapy. Although monoclonal antibodies to cytotoxic T-lymphocyte associated protein 4 (CTLA-4), programmed cell death 1 (PD-1), and programmed cell death ligand 1 (PD-L1) have revolutionized oncologic management, these agents may result in a spectrum of immune-related adverse events (irAE) of which dermatologic toxicities are among the most frequent. Prompt recognition and management of irAE is essential for dermatologists caring for the expanding population of cancer patients exposed to these drugs. Cutaneous toxicities range from mild cases to severe and life-threatening presentations that may cause significant morbidity and mortality. This review provides an overview of severe cutaneous adverse reactions (SCARs) that may develop during ICPi therapy, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP). In addition, immunobullous disorders, erythroderma, neutrophilic dermatoses, and cutaneous eruptions associated with systemic manifestations are discussed.

STUDY OBJECTIVE: Emergency department (ED) consultation is a common practice. There are few data on consultant availability or changes in availability over time, which may hinder resource planning and allocation. We conduct serial surveys of Massachusetts EDs to investigate these trends. METHODS: We surveyed ED directors in Massachusetts in 2006 (n=61 EDs), 2009 (n=63), and 2015 (n=63) about ED characteristics in the previous year, including specialty-specific consultant availability in person (yes/no) and continuous consultant availability (yes/no). We tested trends in consultant availability (P for trend) and used multivariable logistic regression to calculate odds of continuous availability in 2014 versus 2005. RESULTS: Response rates were greater than 80% each year. From 2005 to 2014, there was an increase in the median number of annual ED visits from 32,025 (interquartile range [IQR] 23,000 to 50,000) to 42,000 (IQR 26,000 to 59,300), number of full-time attending physicians from 11 (IQR 8 to 16) to 12 (IQR 8 to 22), and number of full-time ED nurses from 27 (IQR 17 to 54) to 42 (IQR 25 to 65). In adjusted models, there was a significantly reduced odds of consultant availability in 2014 versus 2005 for general surgery (odds ratio [OR] 0.05; 95% confidence interval [CI] 0.01 to 0.35), neurology (OR 0.39; 95% CI 0.17 to 0.86), obstetrics/gynecology (OR 0.40; 95% CI 0.16 to 0.97), orthopedics (OR 0.34; 95% CI 0.13 to 0.89), pediatrics (OR 0.19; 95% CI 0.06 to 0.54), plastic surgery (OR 0.10; 95% CI 0.03 to 0.32), and psychiatry (OR 0.25; 95% CI 0.12 to 0.52). CONCLUSION: In Massachusetts EDs between 2005 and 2014, ED consultant availability significantly declined despite accounting for other ED characteristics.
