Studies have suggested that patients with PCOS tend to be more treatment resistant to light-mediated depilation compared with their non-PCOS counterparts. We conducted a retrospective assessment of 29 hirsute patients treated between January 2006 and February 2007 to assess whether those with unsatisfactory hair clearance after treatment with intense pulsed light (IPL) were predominantly hyperandrogenic. The number of IPL sessions was also recorded for those patients failing to improve on treatment. Seventy-six percent had satisfactory hair clearance where hyperandrogenic patients dominated. All patients required an average of six treatments before discharge. Eighty-eight percent of poor responders were normoandrogenic. Our hyperandrogenic cohort appeared more responsive to IPL than the normoandrogenic patients. From our observations, the presence of hyperandrogenism does not indicate treatment resistance. This standpoint is unique and warrants a randomized trial directly comparing the two groups to investigate whether a positive or negative relationship actually exists.

Global Delphi consensus on treatment goals for generalised pustular psoriasis.
Br J Dermatol
January 2025
Department of Dermatology, Yale University, New Haven, CT, USA.
Background: Generalised pustular psoriasis (GPP) is a chronic, systemic, neutrophilic inflammatory disease. A previous Delphi panel established areas of consensus on GPP, although patient perspectives were not included, and aspects of treatment goals remain unclear.
Objectives: To identify and achieve consensus on refined, specific treatment goals for GPP treatment via a Delphi panel with patient participation.

Keratinocyte carcinomas (KCs) are commonly located on the scalp and often treated with excision with peripheral and deep en face margin assessment (PDEMA), with Mohs micrographic surgery (MMS) being the most frequently used method. Resection of these malignancies results in wounds with a wide variety of sizes, ranging from small, sub-centimeter defects, to extensive, nearly complete scalp defects. MMS is often the preferred treatment for tumor resection and margin clearance, as it allows for maximal healthy tissue preservation and has the lowest recurrence rates.

The metabolic conversion of aromatic amines to N-acetylated forms in skin and keratinocytes depends on N-acetyltransferase-1 (NAT1). Common hair color ingredient such as para-phenylenediamine (PPD) causes allergic contact dermatitis. We explored how different electronic substituents on PPD aided NAT1 enzyme biotransform oxidative arylamine (AA) compounds G1-G13 by N-acetylation, NAT-1 activity assays, metabolism, and in vitro clearance investigations in human keratinocytes, while identifying NAT-1 protein levels by Western blot and qRT-PCR.

Background: The increasing prevalence of female pattern hair loss (FPHL) is an alarming concern. Trichoscopy is an important bedside diagnostic tool for the diagnosis of FPHL, but there are very few studies correlating it with disease severity or histopathological findings which would provide a better insight to the treating clinician. Hence, we decided to take up this study.

Significance: Functional near-infrared spectroscopy (fNIRS) is a promising alternative to functional magnetic resonance imaging for measuring brain activity, but the presence of hair reduces data quality.
Aim: To improve research efficiency and promote wider subject inclusivity, we developed the "Mini Comb"-an attachment for commercial fNIRS head caps that can rapidly clear hair with a simple twisting motion.
Approach: To test the utility of the Mini Comb on different hair types, we measured the clearance achieved with eight unique sliding leg extrusions on 10 wigged mannequins of various hair characteristics.
