Sex differences in initial treatment for genital extramammary Paget disease in the United States: A systematic review.

BACKGROUND: Surgery is the standard treatment for genital extramammary Paget disease (gEMPD). OBJECTIVE: To determine if gEMPD treatments and outcomes differ by sex and US region. METHODS: A systematic review was performed of all English-language studies on initial gEMPD treatment in Medline via PubMed, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov. At least 2 reviewers performed title and abstract review and data extraction. Surgical categories included total skinning procedures, partial skinning procedures, Mohs micrographic surgery (MMS), or unspecified surgery. Chi-squared tests of association were used for comparisons. RESULTS: A total of 60 studies comprising 302 (79.7%) female and 77 (20.3%) male patients met criteria. Women were most often initially recommended partial skinning procedures. In all, 74 (24.5%) women and 0 men underwent a total skinning procedure. Men were more likely to be offered MMS than women (40.3% vs 1.9%, P < .0001), despite men having a significantly greater extent of disease involving the perineum and perianal skin (21.1% vs 1.7%, P < .0001). Treatment recommendations varied by US region. LIMITATIONS: Only 20 states were represented. CONCLUSION: Women are more frequently offered total skinning procedures for gEMPD while men are more frequently offered MMS. MMS offers less recurrence and morbidity than total skinning procedures and should be recommended equally to both female and male patients with gEMPD.

Comparing clinical acne vulgaris severity to adolescent and parent perceptions of acne severity and impact on quality of life.

BACKGROUND/OBJECTIVES: Little research has compared clinician acne severity assessment with either adolescent- or parent-rated scales of acne severity or impact on quality of life (QOL). We sought to assess how adolescents and their parents perceive the severity and impact of acne on the adolescent's QOL and correlate this with clinical severity. METHODS: Each adolescent and a parent completed a validated QOL survey regarding the adolescent's acne and rated the adolescent's acne severity and QOL impact using a Likert scale. Clinicians assessed the adolescent's acne using a standardized acne severity scale. Statistical analysis compared adolescent scores with respective parent scores or with clinician assessment using a paired t test or Spearman rank-order correlation test. RESULTS: The Likert impact score more accurately reflected acne impact on QOL for adolescents than for parents when considering the validated QOL survey as the gold standard (r2  = .56 vs r2  = .36). Likert scores for adolescents and parents were weakly correlated for acne severity but not for acne QOL impact (r2  = .36 vs r2  = .18). Correlations of acne severity scores between clinician and either adolescent or parent were weak. CONCLUSIONS: Parents and adolescents are in relative agreement regarding acne severity and QOL impact. However, parent and adolescent perceptions are disparate from clinician acne assessment. It is important that physicians identify and consider adolescent and parent perceptions in addition to clinical assessment to better inform the approach to acne management.

Bullous dermatoses secondary to anti-PD-L1 agents: a case report and review of the literature.

Immune checkpoint inhibitors are used to treat numerous malignancies but may be associated with severe adverse events. Bullous dermatoses, chiefly bullous pemphigoid (BP), are potentially progressive adverse events that cause blistering skin lesions and may involve a significant body surface area. Herein, we report an 87-year-old man with urothelial cell carcinoma undergoing atezolizumab treatment who presented with an acute-onset blistering eruption. Biopsy revealed a subepidermal bulla, direct immunofluorescence revealed linear IgG and C3 deposits at the dermal-epidermal junction, and serum studies revealed elevated levels of antibodies to BP180 and BP230. Anti-PD-L1-induced BP was diagnosed, immunotherapy was withheld, and he was treated with oral doxycycline with niacinamide and clobetasol ointment. He restarted atezolizumab and has successfully received four cycles (every 3 weeks) while continuing this BP treatment regimen. A literature review revealed eight other cases of anti-PD-L1-induced bullous disorders. The incidence of bullous dermatoses with anti-PD-1/anti-PD-L1 agents combined is 1%, whereas the reported incidence for anti-PD-L1 agents alone ranges from 1.3-5%, raising concerns for a higher overall risk. In addition to our case, only one other case reported successful resumption of immunotherapy. Early control and management of immunotherapy-induced BP may reduce complications and prevent treatment discontinuation.

Hyperkalemia in women with acne exposed to oral spironolactone: A retrospective study from the RADAR (Research on Adverse Drug Events and Reports) program.

PURPOSE: The necessity of serum potassium monitoring for healthy women who are prescribed spironolactone for acne has been debated. The aim of this study was to compare the incidence of hyperkalemia in women 18 to 45 years of age to that in women 46 to 65 years of age, when treated with oral spironolactone for acne. METHODS AND MATERIALS: Data for all women 18 to 65 years of age who were prescribed oral spironolactone by a dermatologist for acne between January 2006 and October 2016 were extracted for analysis. Retrospective data were included for women who exhibited baseline serum potassium within the normal limits and who had repeat serum potassium monitoring within 12 months after initiation of spironolactone. The rate of incident hyperkalemia was determined. RESULTS: Of 618 women who received spironolactone for acne, 133 had serum potassium monitoring both before and after spironolactone initiation. Nine were excluded due to confounding comorbidities. Of the remaining 124 women, the mean age at initiation of spironolactone was 32 years (range, 18-57 years); 112 women were in the 18 to 45 years age group, and 12 were in the 46 to 65 years age group. All women had serum potassium within normal limits at baseline. Women in the 46 to 65 years age group had a significantly higher rate of incident hyperkalemia after spironolactone initiation compared with women 18 to 45 years of age (2 of 12 women [16.7%] vs. 1 of 112 women [< 1%]; p = .0245). CONCLUSIONS: Although controversy surrounds the clinical utility of serum potassium monitoring in healthy women exposed to spironolactone for acne, based on the findings from this large patient population, monitoring of serum potassium is warranted for women over 45 years of age given an age-related greater risk of hyperkalemia.

Genital Angiokeratomas in Adult Men and Women: Prevalence and Predisposing Factors.

INTRODUCTION: There is a paucity of prevalence data for genital angiokeratomas in adults. The objective of this article is to determine prevalence of genital angiokeratomas in adults as a function of sex, age, and race/ethnicity. METHODS: A cross-sectional study was conducted over 11 months during 2013 and 2014 using a convenience sample of adult men and women consenting to genital examination during melanoma screening and surveillance by a senior dermatologist in an outpatient clinic. The analysis was conducted from April through December 2016. RESULTS: Of 213 white/European American adults examined (127 men and 86 women), genital angiokeratomas were detected in 30.0% (64/213). Presence of at least one genital angiokeratoma was significantly associated with male sex (odds ratio [OR], 2.4; 95% confidence interval [CI], 1.3-4.5; P < .001) and age older than 50 years (OR, 3.4; 95% CI, 1.7-6.7; P = .008). CONCLUSIONS: Genital angiokeratomas are relatively common in adults of white/European American origin and important to recognize because of their benign nature and occasional confusion with other tumors.
