This case report describes a 62-year-old man with psoriasis who developed a unique nail abnormality after two months of treatment with the oral retinoid etretinate, alongside hair thinning and cheilitis.

This case report describes a 47-year-old woman who experienced reversible curling of her hair during treatment with valproic acid, suggesting potential side effects on hair texture.

In this study, researchers reported that adenosine stimulated hair shaft elongation in cultured human hair follicles by promoting proliferation and prolonging the anagen phase, suggesting the A2B adenosine receptor in outer root sheath keratinocytes as a promising target for treating hair growth disorders like alopecia.

This study observed that exosomes derived from adipose-derived stem cells significantly enhanced bone marrow mesenchymal stem cell migration and osteogenesis, leading to improved bone regeneration in a rat model of calvarial defects.

This study demonstrated that skin organoids derived from human stem cells can model cutaneous tuberculosis, revealing that fibrosis development in Mycobacterium tuberculosis-infected organoids is linked to the PI3K-AKT and AP1 pathways in fibroblasts, and suggesting the potential for antifibrotic treatment evaluation.

This study examined 16 sporadic trichoblastic tumors and found that although one showed malignant transformation, clinical follow-up revealed no residual or metastatic disease. RNA sequencing indicated a high tumor mutational burden and absence of a UV-related signature, helping to distinguish these tumors from similar growths.

This review details the expression and diverse functions of melatonin receptors in non-neural tissues and reports no new clinical findings, emphasizing their potential as therapeutic targets across various physiological and pathological processes.

This review discusses the use of antiandrogens like flutamide and its derivatives in prostate cancer treatment and highlights the need for next-generation antiandrogens for improved efficacy; it reports no new clinical results.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

Minoxidil effectively controls blood pressure in severe cases, but has serious side effects and causes hair growth in women.

This review summarizes a meta-analysis suggesting that finasteride is most effective for improving symptoms and urinary flow in men with large prostates experiencing benign prostatic hyperplasia.

This study found that Avicennia marina extract significantly inhibited 5α-reductase type 1 activity in human hair dermal papilla cells, suggesting its potential use for treating androgenic alopecia.

This exploratory study found that cannabidiol (CBD) at higher concentrations may inhibit hair growth by promoting the onset of catagen in human hair follicles, while lower concentrations showed potential anti-inflammatory effects without promoting catagen.

This study found that the n-hexane fraction from Leea indica leaves significantly increased hair growth in mice and showed potential as a natural treatment for alopecia.

This study reported that compounds isolated from Alpinia zerumbet significantly promoted hair cell growth and exhibited anticancer activity in cell cultures, suggesting potential as treatments for alopecia and cancer.

This study found that mixtures used in permanent hair dyes had irritant effects on reconstructed human epidermis, while individual ingredients alone did not.

This study explored using a chitosan oligomer coating for topical delivery of dutasteride-loaded nanostructured lipid carriers, aiming to reduce systemic exposure and cytotoxicity.

This study found that exposing adult esophageal epithelial cells to skin stroma can induce them to transition toward a hair follicle identity, with HIF1a playing a crucial role in this conversion process.

This study found that proretinal nanoparticles, applied topically, are safe and effective for penetration into hair follicles, enhancing retinoid biological activity in the skin while reducing irritation compared to conventional retinal formulations.

This study found that obesity in women may impair endometrial stromal function and contribute to reproductive complications, possibly due to metabolic influences rather than immune cell differences.

Hair follicle samples effectively show how well the drug MK-0752 targets and engages with the Notch pathway.

Epirubicin is as effective as doxorubicin for cancer treatment with less heart damage, but doesn't work on doxorubicin-resistant cancers.

This study found that combining near-infrared laser phototherapy with indocyanine green application may improve acne vulgaris by reducing active lesions and inflammation without side effects.

This review discusses the multifactorial etiology of hypospadias, including genetic predispositions and possible environmental factors, and highlights the need for further studies on genetic and environmental contributions to its increasing prevalence, without presenting new findings.

This review suggests that androgenetic alopecia may be exacerbated by exposure to ultraviolet radiation and proposes considering it as a photoaggravated condition requiring photoprotection.

Graft-versus-host disease is a complication where donor immune cells attack the recipient's body, often affecting the skin, liver, and gastrointestinal tract.

This study found that men with early-onset androgenic alopecia have a higher risk of needing coronary revascularization before age 60 compared to those with later onset or no hair loss.

This study reports that among men, skin surface hydration and pH change with age, but transepidermal water loss and sebum production show less variation.

This review suggests that skin may largely protect itself from CYP-generated reactive metabolites due to higher conjugating enzyme activities, while highlighting limitations in modeling human skin metabolism experimentally.
