Use of Topical Corticosteroids in the Treatment of Noninfectious Inflammatory Dermatoses of the Scalp: A Survey of Practicing Dermatologists and Dermatology Residents Using Delphi Methodology.

Background: Noninfectious inflammatory dermatoses of the scalp are common, and their symptomsin particular, those affecting appearance, can have a psychological effect that may be disproportionate to their clinical severity. Effective, cosmetically acceptable treatments are important to manage these conditions. Topical corticosteroids form the cornerstone of acute treatment for many of these conditions.

Sun exposure, a relevant exposome factor in acne patients and how photoprotection can improve outcomes.

Background: Acne pathophysiology includes a complex interaction among inflammatory mediators, hyperseborrhea, alteration of keratinization and follicular colonization by Propionibacterium acnes.

Aims: To describe the impact of the exposome on acne and how photoprotection can improve outcomes.

Methods: A narrative review of the literature was carried out; searches with Google Scholar and Pubmed from January 1992 to November 2022 were performed.

Immediate-Onset Linear Effluvium Associated With High-Density Hair Transplantation: A Series of 28 Cases.

We describe 28 patients who experienced effluvium with previously unreported features shortly after hair transplant surgery. Notable features were as follows: a) a linear morphology; b) immediate onset (1-3 days); c) association with dense-pack grafting in areas of receding hairline at the temples (Mickey Mouse pattern); d) a progressive increase in the diameter of the hair loss line (wave-like pattern); e) in some cases, subsequent concentric linear effluvium on the crown (donut pattern); and f) other forms of previously unreported immediate-onset effluvium. The linear morphology could be the result of dense packing, which can cause perilesional hypoxia and loss of miniaturized hairs around the recipient area.
