Interest in and research on hidradenitis suppurativa (HS) have increased during the past decade, resulting in expanded knowledge about associated comorbidities and treatment efficacy. Knowledge about pediatric-onset HS is still limited, based on case studies, small case series, and extrapolation from adult studies. With increasing prevalence of childhood obesity, decreasing pubertal age, and increasing awareness of HS, physicians may start encountering younger HS patients. This review presents an updated discussion on the epidemiology, pathophysiology, and associated comorbidities in HS, with a focus on pediatric and adolescent patients. It also suggests recommendations for investigation and treatment based on current evidence., (Copyright © 2020 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.)

Background: Fear of adverse effects of corticosteroids is common in dermatology and results in medication nonadherence., Objective: To study the efficacy of targeted education in reducing topical steroid phobia., Methods: In this double-blinded, randomized controlled trial, participants in the intervention arm were presented with an educational video and patient information leaflet targeting common misconceptions of topical corticosteroids. Steroid phobia was assessed with the topical corticosteroid phobia (TOPICOP) scale, medication adherence with the Elaboration d'un outil d'evaluation de l'observance des traitements medicamenteux (ECOB) score, and quality of life with the Dermatology Life Quality Index (DLQI)., Results: The study randomized 275 patients. The mean TOPICOP score in the intervention arm decreased (improved) from 41.9 (SD, 17.4) to 37.1 (SD, 20.0) and to 33.8 (SD, 19.0) at 1 month and 3 months, respectively, with the reduction arising from the knowledge domain but not the fears and behaviors domain. This remained statistically significant after adjusting for demographic confounding with an expected reduction of 4.22 points (P = .031). After accounting for demographic factors, there was no statistical difference in medication adherence and quality of life. Limitations include the exclusion of non-English-speaking patients., Conclusion: Targeted education at a single time point improved the TOPICOP score primarily in the knowledge domain but not in the fear domain., (Copyright © 2020 American Academy of Dermatology, Inc.
