Purpose of review: Neutrophilic dermatoses are a heterogeneous group of disorders with significant overlap in associated conditions, clinical presentation, and histopathologic features. This review provides a structural overview of neutrophilic dermatoses that may present in the inpatient setting along with diagnostic work-up and management strategies.

Recent findings: Sweet's syndrome has been found in patients with coronavirus disease 2019 (COVID-19). Pyoderma gangrenosum (PG) has been shown to be equally associated with ulcerative colitis and Crohn's disease. A clinical trial shows that cyclosporine is equally effective as prednisone in treating PG. Neutrophilic eccrine hidradenitis has been found in the setting of newer antineoplastic medications, such as BRAF inhibitors, as well as in the setting of malignancy without chemotherapy exposure.

Summary: Neutrophilic dermatoses are a rare and complex group of dermatoses with varying and overlapping clinical presentations. Physicians should be aware of the growing list of associated diseases in order to build a better differential diagnosis or to potentially investigate for co-existing disease.

Purpose of review: Contact urticaria syndrome includes contact urticaria and protein contact dermatitis. Underreport, underdiagnosis, or misdiagnosis of entities within the contact urticaria syndrome is believed to be common, especially in the occupational setting. This review provides a structured overview of the entities comprised in this syndrome as well as the diagnostic work-up and management strategies.

Recent findings: Contact urticaria syndrome has been increasingly described due to personal protective equipment and hand sanitizers in the context of the COVID-19 pandemic. The use of legal cannabis products has led to a rise in occupational cases of contact urticaria to cannabis. A declining trend in the evolution of contact urticaria has been described for natural rubber latex allergy due to the use of synthetic gloves. Prick test has been proposed as a screening method, particularly if multiple products are to be tested, instead of the classical sequential scheme.

Summary: Physicians should be aware of the growing number of culprit agents leading to contact urticaria syndrome. Clinical presentation may be challenging since it includes immediate urticaria and/or eczema and even more generalized reactions. Diagnosis requires a high degree of suspicion, detailed occupational history, and complementary tests, including skin testing. The best treatment is to avoid contact with the culprit agent and to implement preventive measures.

Purpose of review: We review several important changes affecting dermatology during the COVID-19 pandemic, beginning in March 2020. Specifically, we focus on the impact of the COVID-19 pandemic on physician trends in employment, delivery of care via teledermatology, and burnout, resilience, and wellness.

Recent findings: More physicians are now employed by corporate entities than prior to the pandemic. Teledermatology can be utilized effectively and integrated into current care models; however, the continued use of teledermatology will largely depend on financial compensation. The COVID-19 pandemic was a source of burnout for all physicians, including dermatologists, and impacted how many people view their work.

Summary: The COVID-19 pandemic pushed physicians to change their employment, required them to implement telehealth rapidly, and forced them to re-evaluate their priorities. Prior to the pandemic, more physicians transitioned into employed positions as compared to physician-owned practices. Multiple reasons for consolidation exist, but the trend accelerated during the COVID-19 pandemic for all medical specialties. Similarly, teledermatology was utilized prior to the pandemic, but its use exploded in the early days of the COVID-19 pandemic and continues to this day. The future of teledermatology though depends primarily on insurance reimbursement for these visits as well as both patient and physician preferences for continued usage. Lastly, wellness became a major focus in medicine as the pandemic took a significant toll on physicians, including dermatologists.

Purpose of review: To summarize diagnostic and therapeutic management of COVID-19 in the outpatient setting for dermatologists.

Recent findings: Paxlovid (nirmatrelvir-ritonavir) is the preferred treatment in patients with mild symptoms at high risk of progression to severe SARS-CoV2 infection. Additional options include monoclonal antibodies (bebtelovimab), remdesivir, and molnupiravir.

Summary: Dermatologists need to be aware of recent developments in diagnostic and therapeutic management of COVID-19 in the outpatient setting, as their patients may rely on dermatologists to provide advice, particularly in cases where treatments for dermatological disease may impact the risk of COVID-19 and/or vaccine efficacy.

Purpose of review: The overall purpose of this review was to characterize and summarize cutaneous eruptions associated with coronavirus disease 2019 (COVID-19) as well as COVID-19 vaccination.

Recent findings: Cutaneous eruptions associated with COVID-19 infection have a reported frequency of 1-20%. Increased COVID-19 disease severity has been associated with morbilliform exanthems, urticaria, retiform purpura, and livedo racemosa. Papulovesicular eruptions were associated with a milder COVID-19 disease course. A range of dermatoses have also been reported with COVID-19 vaccination but have rarely prevented subsequent vaccination.

Summary: Dermatologists should be aware of the associations between COVID-19 disease severity and cutaneous eruptions. Livedo racemosa and retiform purpura are particularly associated with increased disease severity and death. In the setting of COVID-19 vaccination, cutaneous eruptions can largely be managed symptomatically and very rarely do these reactions prevent subsequent vaccination.

Purpose of review: Rituximab has transformed the treatment of B-cell malignancies and rheumatoid arthritis in the past 2 decades. More recently, this anti-CD20 monoclonal antibody has seen increasing usage in the field of dermatology. This review highlights the evidence supporting its use in several important dermatologic conditions.

Recent findings: Key recent findings include the 2018 FDA approval of rituximab for the treatment of moderate-to-severe pemphigus.

Summary: Data from randomized controlled trials have demonstrated the efficacy of rituximab in pemphigus, ANCA-associated vasculitis, and cryoglobulinemic vasculitis. More limited data suggests its use in recalcitrant cases of diseases such as pemphigoid, epidermolysis bullosa acquisita, and dermatomyositis. There is scarce evidence and mixed results for rituximab when studied in cutaneous polyarteritis nodosa and cutaneous lupus erythematosus.
