This review discusses definitions of polycystic ovary syndrome and reports no new clinical results; the authors support using modified 1990 NIH criteria and acknowledge ongoing evolution as research advances.

This review discusses the definition of polycystic ovary syndrome proposed by the AE-PCOS Society Task Force, emphasizing hyperandrogenism, ovarian dysfunction, and excluding related disorders, while noting potential variations needing more research.

This review summarizes how genetic studies using conditional β-catenin loss- and gain-of-function mice have advanced understanding of canonical Wnt signaling's role in embryonic development, adult stem cell maintenance, and cancer modeling.

This review discusses genderqueer and non-binary identities and explores how mental health professionals can support these marginalized communities, but it reports no new findings.

This review discusses the diagnostic criteria and management strategies for Polycystic Ovary Syndrome (PCOS) and highlights the need for comprehensive clinical assessment, but does not report new clinical findings.

In this study, repressing β-catenin/Lef1 signalling in mouse epidermis led to progressive hair loss, dermal cysts, and spontaneous skin tumors with sebaceous differentiation, indicating altered keratinocyte differentiation and potential tumourigenic processes.

In this study, among patients undergoing chemotherapy for breast or gynecologic cancers, smell and taste functions significantly decreased but largely recovered three months post-treatment, with taxane-based regimens causing more severe taste disturbances.

Ritlecitinib effectively treats alopecia areata and is well-tolerated.

This review discusses recent advancements in congenital adrenal hyperplasia research, including improved diagnostic techniques, alternative treatments, and insights from long-term outcome data, but it reports no new clinical results.

This study explains finasteride's high potency and specificity as a mechanism-based inhibitor for treating benign prostatic hyperplasia by detailing its interaction with human type 2 steroid 5α-reductase.

This study found that oral administration of finasteride to pregnant rats caused dosage-related developmental toxicities, including hypospadias and decreased anogenital distance in male offspring.

This study identified a genetic locus associated with idiopathic scoliosis in females, which might influence spinal gene expression and was previously linked to protection from early-onset alopecia.

In this study, oral biotin improved hair growth, strength, and combability in a child with uncombable hair syndrome, while hair in two others slowly improved without biotin.

This study found that dutasteride increased hair growth and restoration in men with androgenetic alopecia more effectively than finasteride and was well tolerated over 24 weeks.

This article provides diagnosis and treatment guidelines for hyperandrogenic disorders in women but reports no new clinical results; it offers a summary of accepted scientific information and suggestions for clinical practice.

This study found that in hamster flank organs, 17βC inhibited enlargement caused by topical testosterone but not by DHT, suggesting potential use in androgen-related skin disorders like acne.

Vitamin D3 affects cell differentiation in specific skin areas.

In this study, finasteride doses as low as 0.2 mg per day significantly reduced both scalp skin and serum DHT levels in men with androgenetic alopecia.

This study demonstrated that hair follicle-derived cells can induce hair follicle formation in an in vitro skin organ culture system using human retroauricular skin specimens.

Minoxidil is a new drug that lowers blood pressure.

This study concluded that Wnt/β-catenin signaling, through Shh and Bmp pathways, is crucial for determining hair follicle fate in embryonic epidermal development.

Fibronectin and other basement membrane components increase during hair growth and decrease during rest.

This study found that Wnt secretion is important for maintaining skin homeostasis in mice, as Evi-deficient mice developed psoriasis-like skin lesions and had an imbalance in immune cell populations.

This article proposes two new categories of cicatricial alopecia—“unstable” and “stable”—and suggests surgical excision as preferred over hair transplantation, especially for unstable cases.

This report suggests that clinically inapparent sweat gland tumors might influence hair loss in a specific patient case.

This review offers evidence-based recommendations for diagnosing and treating female pattern hair loss, emphasizing clinical assessment and starting treatment with minoxidil, while noting that measurement of certain hormones and vitamins is optional.

This review describes how recent discoveries in genetic defects and alternative pathways in androgen biosynthesis are reshaping our understanding of male sexual differentiation, but it presents no new clinical findings.

This study suggests PPAR isotypes play distinct roles in skin, influencing epidermal barrier formation, sebocyte differentiation, and lipid production, with potential implications for treating skin disorders.

This article discusses the distribution of extracellular matrix molecules in human hair follicles and reports no new results.

This article explains why modern hair transplant techniques can be effective for women with pattern hair loss, despite this being underrecognized.
