Atopic dermatitis (AD) is a prevalent inflammatory skin condition that, depending on its severity, can cause enormous morbidity. Corticosteroids and systemic immunosuppression, traditionally standard of care for difficult-to-treat disease, have many undesirable side effects. The desire for targeted treatments along with an improved understanding of the pathophysiology of AD has spurred the development of novel treatments. In this article, we review promising new treatments and discuss how their targets-IL-13, IL-31, OX40 (CD134), and the Janus kinase family of proteins-participate in the pathogenesis of AD. We review the published phase II and III data for dupilumab, tralokinumab, lebrikizumab, nemolizumab, anti-OX40 antibody, baricitinib, abrocitinib, and upadacitinib. The introduction of new agents may offer new options, but it remains to be seen how narrow-acting agents, like single interleukin inhibitors, will compare in safety and efficacy to broad-acting agents such as JAK inhibitors. Key Points Our better understanding of the pathophysiology of AD has resulted in an explosion of research into new immunotherapies for this patient population. Multiple new agents targeting IL-13, IL-31, OX40 (CD134), and Janus kinase proteins may be effective for AD.

Background: Scabies is a neglected skin disease, and little is known about current incidence and treatment patterns in the United States. The purpose of this study was to examine demographic data, treatment types, success of treatment, and misdiagnosis rate of scabies in an outpatient dermatology clinic.Methods: A retrospective chart review of patients diagnosed with scabies within the past 5 years was performed.Results: A total of 459 charts were identified, with 428 meeting inclusion criteria. Demographic data, diagnostic method, treatment choice, misdiagnosis rate, treatment failure, and itching after scabies are also reported. Children were the largest age group diagnosed with scabies, at 38%. Males (54%) were diagnosed with scabies more than females. The majority of diagnoses were made by visualizing ova, feces, or mites on light microscopy (58%). At the time of diagnosis, 45% of patients had been misdiagnosed by another provider. Topical permethrin was the most common treatment used (69%), followed by a combination of topical permethrin and oral ivermectin (23%), oral ivermectin (7%), and other treatments (1%).Conclusion: Our findings suggest that more accurate and faster diagnostic methods are needed to limit unnecessary treatment and expedite appropriate therapy for scabies.

This is a review article summarizing the diagnosis, evaluation and management of dermatomyositis (DM). Key clinical features and variations in clinical presentation of DM are highlighted, and the evidence-based treatments for this condition are discussed.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening conditions with high morbidity and mortality. Supportive care management of SJS/TEN is highly variable. A systematic review of the literature was performed by dermatologists, ophthalmologists, intensivists and gynecologists with expertise in SJS/TEN to generate statements for supportive care guideline development. Members of the Society of Dermatology Hospitalists (SDH) with expertise in SJS/TEN were invited to participate in a modified, online Delphi-consensus. 9-point Likert scale questionnaires regarding 135 statements were administered. The RAND/UCLA appropriateness method was employed to evaluate and select proposed statements for guideline inclusion; statements with median ratings of 6.5-9 and disagreement index ≤1 were included in the guideline. For the final round, the guidelines were appraised by all the participants. An evidence-based discussion and recommendations for hospital setting and care team, wound care, ocular care, oral care, urogenital care, pain management, infection surveillance, fluid and electrolyte management, nutrition and stress ulcer prophylaxis, airway management, and anticoagulation in adult patients with SJS/TEN are included.
