We describe an unusual presentation of Bier anemic spots, cyanosis, and urticaria-like eruption (BASCULE) syndrome in a 15-year-old male, recalcitrant to low-dose anti-histamines, which subsequently responded to high-dose fexofenadine.

Guidelines are inconsistent regarding annual QuantiFERON® TB Gold (QFT) tests in children taking biologics for dermatological conditions, and there is limited research on seroconversion, especially in regions with high tuberculosis (TB) prevalence. A retrospective review of pediatric patients taking biologic treatment for psoriasis or hidradenitis suppurativa (HS) who had one baseline and at least one follow-up QFT test was conducted to assess for seroconversion during treatment. Thirty-two patients were included, with no instances of seroconversion. These findings suggest that routine annual TB rescreening for pediatric patients taking biologic therapy for dermatologic conditions may not be necessary without additional TB exposure risks or symptomatology.

PIK3CA-related overgrowth spectrum (PROS) encompasses different clinical entities caused by somatic activating mutations in PIK3CA. Among PROS, CLOVES syndrome represents a severe phenotype with poor survival rate. We present the case of a 4-month-old girl with CLOVES syndrome successfully treated with alpelisib, a PIKC3A inhibitor.

Background: The use of progestin-only long-acting reversible contraception (LARC) may be a risk factor for acne. Few studies have focused primarily on the effects of hormonal LARC on the development or exacerbation of acne in adolescents and young adults. We sought to understand the incidence and management of acne following hormonal LARC insertion in this adolescent/young adult population.

Methods: A secondary data analysis was conducted of prospectively collected quality improvement (QI) data from the Adolescent Medicine LARC Collaborative. Subjects were evaluated by clinicians in adolescent medicine clinics at participating study sites, and acne severity was documented using a standardized recording instrument and scale. Descriptive statistics were reported as frequencies and percentages for categorical variables or mean and standard deviation (SD) for continuous variables. We compared demographic and clinical characteristics by those who had worsening acne, accounting for site inter-correlation using Cochran-Mantel-Haenszel chi-square tests for categorical variables and linear generalized estimating equation (GEE) regression for continuous variables.

Results: Of 1319 subjects who completed LARC insertion, 28.5% (376/1319) experienced worsening acne following use of progestin-only LARC. Acne was a contributing factor to LARC removal in only 3% (40/1319), and the sole reason for removal in 0.4% (5/1319) of all subjects. As this was a secondary analysis of prospectively collected QI data, limitations of this study include incomplete or inaccurate documentation of acne severity. Moreover, LARC insertions without follow-up/removal visits or with only follow-up/removal within 8 weeks of insertion were excluded from our study, which may also bias results.

Conclusions: Adolescents and young adults seeking progestin-only LARC should be counseled about the potential for developing acne or experiencing a worsening of existing acne during LARC use. However, acne was not a common reason for LARC discontinuation.

The expertise of both dermatology and rheumatology may be beneficial when managing autoimmune conditions with cutaneous and systemic manifestations in children. This survey study was directed to pediatric dermatologists who participate in combined pediatric dermatology-rheumatology clinics; 13 sites in North America responded. The results provide information regarding clinic operations, benefits, and barriers to establishment. These findings have the potential to help institutions establish or modify combined pediatric dermatology-rheumatology clinics, although further research is needed to determine their impact.
