This review discusses the complex interaction between androgens and hair follicle biology, highlighting the need for a better understanding to improve hirsutism treatments, but reports no new results.

This study discusses the potential association between low vitamin D levels and insulin resistance, suggesting that vitamin D deficiency may contribute to disorders like obesity and diabetes, but emphasizes the need for further research to confirm these links.

This study reported that squamous cell carcinomas of the scalp can become extraordinarily aggressive, highlighting the need for early diagnosis and careful use of treatment strategies like wide excision and radiation therapy.

In this study, a psoriatic patient developed retinoid-induced granulation tissue after long-term oral etretinate therapy, suggesting prolonged use may lead to delayed wound healing.

This case report describes an 89-year-old woman with a recurrent benign proliferating trichilemmal tumor on her back, highlighting its misdiagnosis as a sebaceous cyst and successful excision with free margins.

This article discusses the structures surrounding hair follicles and introduces aspects like follicle groups and the dermal sheath, but it reports no new research findings.

This review discusses the connection between hair follicles and dermal adipose tissue, suggesting that improving the adipogenic environment could be important for treating alopecia and enhancing hair restoration procedures, but reports no new results.

This study found that mange was the most common cause of alopecia in dogs, with cases being more prevalent during the summer and among dogs less than one year old.

In this study using a mouse model, researchers found that expressing Lef1 in dermal fibroblasts may enhance skin regeneration without affecting normal development.

This study reported that squamous cell carcinomas of the scalp can be extraordinarily aggressive, potentially metastasizing and causing death, highlighting the need for early diagnosis and careful treatment approaches.

In this study of HIV+ men with low CD4 and testosterone levels, testosterone replacement therapy significantly improved sexual interest, erectile functioning, and sexual satisfaction over an eight-week period.

In this report, two cases of melanocytic matricoma, a rare benign hair follicle lesion that mimics melanoma and basal cell carcinoma, were described and successfully treated with complete surgical excision. Histological analysis was crucial for differentiation from similar malignant lesions.

The vitamin D receptor helps control hair growth and may protect against certain skin tumors.

In this study, Mills et al. reported that inoculating human pericytes into murine wounds delayed dermal repair, revealing a need for better understanding of pericyte activity during skin injury repair.

This review explores the cellular and molecular basis of wound-induced hair neogenesis and its relationship with aging but does not report new clinical results, highlighting areas for future research.

This chapter reviews common drug-related and systemic disorder-induced alopecias, focusing on their epidemiology, causes, symptoms, diagnosis, and treatment, but reports no new findings.

This report describes three cases of hypertrichosis lanuginosa acquisita occurring after cytotoxic chemotherapy for cancer, suggesting a possible relationship which is discussed alongside a review of existing literature.

This review discusses the role of zinc in skin physiology related to vitiligo and reports no new clinical results; the authors emphasize its potential in pathogenesis and treatment.

This study found that bursts of ERK activation in the epidermis of mice were linked to cell division, supporting synchronized cell proliferation and transient ERK activity in living tissues.

Telogen effluvium is a condition where hair falls out due to various factors like illness, stress, or nutrient deficiency.

This case report describes a trichoblastoma in a 58-year-old man's leg, which was successfully excised without recurrence observed after 9 months.

This study demonstrates that miniaturized hair follicles in female pattern hair loss overexpress nuclear aryl hydrocarbon receptors, suggesting a potential role for environmental pollutants in this condition.

This study reviewed the literature on pilomatrix carcinoma and reported that while wide local excision was the most definitive treatment, local recurrences and metastases were common.

This source reports that biotin, a water-soluble vitamin B7, may benefit skin, hair, and nail health, including various types of alopecia, without the risk of hypervitaminosis even at high doses.

Some medications can improve skin conditions, while lifestyle factors like smoking and drinking may worsen them; treatments like monoclonal antibodies and imiquimod cream show promise for certain skin diseases.

This review explores how sex differences influence the pathophysiology, incidence, and treatment outcomes of ischaemic heart disease, and emphasizes the need for more sex-specific research.

This study found that in mice, Bacillus anthracis infections destroy hair follicles by progressing inward from the surface and clear when inflammatory cells disperse the bacteria after 3-4 days.

Skin problems are common in Bangladesh due to arsenic, prompt treatment of diabetic foot ulcers is crucial, maternal transmission causes most neonatal herpes, treatments for pediatric vasculitis are effective, the chickenpox vaccine works, more frequent UVB therapy helps psoriasis, certain jobs increase hand dermatitis risk, monoclonal antibodies treat psoriasis well, lifestyle affects psoriasis, alefacept improves psoriasis, imiquimod cream partially clears basal cell carcinoma, and iron may not help chronic hair loss.

Other common signs, not just the well-known immune cells around hair bulbs, are important for diagnosing hair loss from alopecia areata.

All medications can cause skin rashes, often without a clear cause, and better tests are needed to identify these drug-related skin issues.
