This review discusses the safety of testosterone therapy for postmenopausal women and concludes that, aside from hirsutism and acne, it appears safe at physiological doses for several years, though more long-term studies are needed.

This study found that procyanidin oligomers, particularly dimers and trimers, significantly promoted hair growth in mice and hair epithelial cell cultures, suggesting potential use as hair growth agents.

This review discusses the impact of menopause-related oestrogen deficiency on skin ageing and suggests that oestrogen use may improve collagen and skin elasticity, but it reports no clinical trial results.

This review discusses the relationship between estrogen deficiency and skin aging in postmenopausal women, noting potential benefits of estrogen use on skin collagen and elasticity, but reports no new clinical results.

In this study, seasonal hair loss was most pronounced in low-ranking male vervet monkeys, and changes in scrotal color and hyperpigmentation also correlated with hair loss, but underlying causes were not identified.

This article reviews treatment options for male-pattern and female-pattern hair loss, telogen effluvium, and alopecia areata, but provides no new clinical results; algorithmic management approaches are included.

This study found that anti-TNF therapy-induced alopecia exhibits distinct clinical and histopathological features and can mimic psoriatic alopecia and alopecia areata, with some patients improving with topical treatment.

This study found that the co-activator CBP enhances the agonistic action of hydroxyflutamide on androgen receptors, suggesting a mechanism for therapy resistance in prostate cancer.

In this study, distinct metabolic profiles were identified in women with PCOS, suggesting potential biomarkers for diagnosis based on changes in lipid and androgen metabolism.

This review discusses evidence for alopecia areata treatments, highlighting their ability to stimulate hair growth but noting limited data on long-term efficacy and impact on quality of life.

This article reviews the characteristics and classification of SAHA syndrome and its relationship with other conditions, without presenting new clinical findings.

This review found that infliximab, golimumab, and some forms of radiotherapy significantly improved nail psoriasis compared to controls, although they could have serious adverse effects and are not commonly used specifically for nail issues.

This paper discusses the hypothesis that anti-acne agents may work by reducing FGFR2 signaling, and emphasizes FGFR2's potential role in acne pathogenesis, but it reports no new experimental findings.

Pregnancy often causes skin changes like darkening, stretch marks, and hair growth, which may improve after childbirth.

This study found that dermatological issues, such as xerosis and pigmentation, are common in chronic kidney disease patients and increase with the severity and duration of the disease, indicating that dialysis often exacerbates these conditions.
