    Abstract Background: According to the curriculum guidelines of the Accreditation Council of Graduate Medical Education and the American Board of Dermatology, Mohs micrographic surgery & dermatologic oncology (MSDO) fellows must demonstrate competency in the use of oral skin cancer chemoprophylaxis. The current level of education in this area is unknown.
    Objective: To characterize oral skin cancer chemoprophylaxis education for acitretin and nicotinamide among current MSDO fellows and to compare the clinical indications felt most appropriate for prescribing to a previously published expert consensus.
    Methods: An electronic survey was distributed to all active MSDO fellows by the American College of Mohs Surgery.
    Results: Responses were received from 63 (69.2%) MSDO fellows. Twenty (31.7%) and 37 (58.7%) fellows reported receiving fellowship training on acitretin and nicotinamide, respectively. Fifty-seven (90.5%) intend to prescribe chemoprophylaxis after training. Sixteen (28.1%) and 43 (75.4%) report feeling very comfortable prescribing acitretin and nicotinamide, respectively. Fellow concordance with a previously published expert consensus opinion on appropriate prescribing indications is variable. Forty-one (65.1%) indicated that additional education would increase the likelihood to prescribe after training.
    Conclusion: Although most MSDO fellows intend to prescribe oral skin cancer chemoprophylaxis, a standardized curriculum may promote increased use and concordance with expert consensus recommendations.

    Abstract Background: COVID-19 has significantly impacted cancer care. While previous studies have emphasized treatment modification and prioritized the delivery of cancer care, few have examined this issue from the public perspective.
    Materials and methods: In the following study, we examine how public interest in various forms of cancer treatment has evolved during the pandemic using Google Trends. One-way ANOVA and linear regression tests were used to compare the mean search volume indices of three periods: pre-lockdown, lockdown, and reopening.
    Results/conclusions: Our findings suggest that public interest in cancer treatments decreased during lockdown and returned after reopening but, in general, is still lower than pre-lockdown levels. Despite that, healthcare professionals should strive to provide timely cancer care, assuage patients' fears of healthcare settings, and encourage patients to continue proper cancer screenings.

    Abstract The rising incidence of cutaneous squamous cell carcinoma (cSCC) represents a public health crisis. Although most cases of cSCC are cured with surgical excision alone, high-risk disease requires a coordinated strategy involving accurate staging, possible multimodal therapy, and clinical and radiologic surveillance. In the following review, we present an evidence-based update on the current paradigm of diagnosis and management of cSCC and discuss the most relevant areas of active research related to prognostic staging as well as the appropriate use of radiologic imaging and adjuvant therapy.

    Abstract Drug-induced vasculitis and anticoagulant-related skin reactions are commonly encountered in the inpatient and outpatient settings. The spectrum of clinical presentation is broad and ranges from focal, skin-limited disease, to more extensive cutaneous and soft tissue necrosis, to potentially fatal systemic involvement. The prompt recognition of these adverse events can have a significant impact on patient morbidity and mortality. We highlight the key features of the clinical presentation with an emphasis on primary lesion morphology, distribution, and epidemiology of purpuric drug reactions. The proposed pathophysiology, histologic findings, and therapeutic interventions of these potentially life-threatening diseases are discussed.

    Abstract Background: Potassium hydroxide preparations (KOH) and tissue examinations for ova and parasites (O&P) are cost-effective office-based tests. No studies have quantified their utilization and economic impact.
    Methods: The objective is to determine the billing patterns and costs of office-based diagnostic procedures in the Medicare population. We conducted a cross sectional study using the Part B National Summary Data File (2000-2016) and the Physician and Other Supplier Public Use File (2012-2015) released by the Centers for Medicare & Medicaid Services.
    Results: In 2016, the total number of claims among all providers was 28,432 (KOH) and 52,182 (O&P), representing a decrease since 2000 (KOH, -41.8%; O&P, -43.4%). The total claims for in-office procedures by dermatologists per 10,000 beneficiaries decreased between 2012 and 2015 (KOH, -18.8%; O&P, -26.6%). Fewer dermatologists submitted claims for the tests (KOH, -11.3%; O&P, -16.6%). The total single (SB) and multiple (MB) biopsy claims by dermatologists per 10,000 beneficiaries decreased between 2012 and 2015 (SB, -1.8%; MB, -2.7%). The 2016 aggregate payments (% change since 2000) for KOH and O&P were $163,127.75 (-60.4%) and $299,074.18 (-61.6%), respectively; for SB and MB, they were $240,047,487.98 (+142.3%) and $38,214,117.22 (+79.2%), respectively.
    Conclusion: Fewer dermatologists submit claims for KOH and O&P each year. Future studies should evaluate whether this is due to a loss of cost-efficacy, and secondly, if it is related to decreased reimbursement, burdensome in-office laboratory regulations, or changing provider preferences.
