This review discusses the potential impact of endocrine-disrupting chemicals and body size on pubertal onset and progression, highlighting critical gaps and priorities for future research without presenting new clinical results.

Manage vitiligo with treatments, address emotions, and use camouflage techniques.

This review elaborates on the skin side effects of chemotherapy and emphasizes identifying and managing both common and life-threatening skin reactions, without presenting new clinical findings.

This study observed that acute stress in rats increased neurosteroid levels linked to enhanced GABA(A) receptor function, raising seizure thresholds, while similar effects were seen in mice with deoxycorticosterone administration.

This study identifies mutations in the SRD5A3 gene as a cause of a new type of congenital disorder of glycosylation, impacting mental, ophthalmologic, and cerebellar functions.

In this study, finasteride 1 mg/day for 12 months did not improve hair growth or slow hair thinning in postmenopausal women with androgenetic alopecia compared to placebo.

Hair loss in women is genetic, diagnosed by examination and biopsy, and treated with minoxidil, finasteride, or transplantation.

This study found that while a tip-focused calcium gradient influences localized growth in root hairs and pollen tubes, it is not the primary determinant of growth direction in root hairs of Arabidopsis thaliana.

This review discusses the cutaneous symptoms associated with COVID-19 and their potential use in diagnosing and assessing the severity of the disease, but it reports no new clinical results.

This review summarizes the roles of bone morphogenetic proteins in the development and regulation of normal and diseased skin, but it does not provide new clinical results.

This study found that finasteride improves scalp hair growth in men with male pattern hair loss by reducing scalp dihydrotestosterone levels, but it did not benefit postmenopausal women with female pattern hair loss.

This review of interventions for alopecia areata found no significant treatment benefits for hair growth compared to placebo, indicating a need for larger, well-conducted studies.

In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This study reports that some patients with androgenetic alopecia may also exhibit clinical and histological features of inflammation and fibrosis, similar to those found in lichen planopilaris.

This review discusses recent advancements in understanding and managing congenital adrenal hyperplasia, including improvements in screening, diagnostics, and potential genetic and cell-based treatments, but reports no new clinical findings.

Dermatoscopy and videodermatoscopy are useful for diagnosing and monitoring various skin, hair, and nail conditions.

This review discusses the WNT signaling pathway's involvement in human diseases and highlights recent advances in WNT-related treatments, but it presents no new research findings.

This study found that mice lacking the 1αOHase enzyme, which is responsible for producing a key vitamin D metabolite, showed impaired epidermal differentiation and delayed recovery of skin barrier function after disruption.

This review discusses the dynamic, niche-driven regulation of stem cell states in tissue homeostasis and regeneration, focusing on epithelial stem cells in the mammalian skin, intestine, and lung, without providing new experimental results.

This study found that matriptase, a membrane serine protease, is crucial for maintaining multiple types of epithelial tissues in mice, with its absence leading to severe organ dysfunction and increased permeability.

This review explores finasteride's effects on neuroactive steroid levels and their potential influence on disorders like depression and alcohol withdrawal but reports no new clinical findings.

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 modulating BMP activity in transgenic mice affects the development and characteristics of several ectodermal organs, such as skin, hair, and claws, highlighting a stage-dependent influence on organogenesis.

This study found that reduced cytokinin levels allow plants to adapt to low potassium conditions by enhancing root hair growth, reactive oxygen species accumulation, and expression of a key potassium transporter gene.

This article reviews the classification of hair shaft abnormalities, outlining their diagnostic features, but does not present new research findings.

This review discusses the hyperfunction theory of aging as a key factor in COVID-19 vulnerability, highlighting the potential of anti-aging interventions like rapamycin to reduce this risk.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

This study reports that 2-(1-Adamantyl)-4H-thiochromen-4-on-6-O-sulfamate is the most potent steroid sulfatase inhibitor identified so far, exhibiting 170-fold higher activity than the lead compound estrone sulfamate.

This study found that overexpression of Smad7 in transgenic mice led to severe alterations in multiple epithelial tissues, resulting in early death after birth.

This systematic review reports that "COVID toes" and other skin manifestations can be initial signs of COVID-19, and advises immunosuppressive therapy adjustments only for infected or at-risk patients.
