This study observed that mice with a whole-body deficiency of Cystathionine-β-synthase developed severe hyperhomocysteinemia and related mild symptoms without increased mortality, indicating HHCy may not directly cause end organ damage.

This review discusses the cosmetic and health implications of hirsutism and highlights its potential link to serious underlying disorders, but it presents no new clinical findings.

This case study describes three young females with hirsutism who were diagnosed with different underlying conditions—late-onset congenital adrenal hyperplasia, idiopathic hirsutism, and polycystic ovary syndrome with ovarian thecosis—highlighting the need for reevaluation if initial treatments are ineffective.

This study observed significantly higher hair cortisol concentrations in foals compared to mares, with a strong positive correlation between the two, suggesting that hair cortisol can reflect maternal and fetal cortisol exposure during the last trimester of gestation in horses.

Hyperandrogenism in women often causes acne and excess hair, treatable with lifestyle changes and medications.

This study found that serum HDAC1 levels are significantly higher in patients with alopecia areata compared to those with acne vulgaris and healthy controls, suggesting potential therapeutic opportunities for HDAC inhibitors.

This study identifies novel genetic variants in the NOTCH3 and HTRA1 genes associated with CADASIL and CARASIL, highlighting their potential in supporting clinical diagnosis and informing treatment strategies.

This study identified a novel insertion mutation in the hairless gene that may contribute to the development of congenital atrichia with papular lesions in a Pakistani family.

This study identified complex regulatory elements and interactions involving the Hr gene and HR protein that are crucial for hair follicle formation and cycling in mammals.

Hair cortisol analysis can help diagnose stress-related conditions but needs more refinement for widespread use.

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 a peripilar white gray halo around hair emergence is a highly specific and sensitive dermatoscopic feature for diagnosing central centrifugal cicatricial alopecia in African American patients with mild central thinning.

This case study suggests a potential connection between insulin resistance-induced diabetes and the development of migraine symptoms in a patient with HAIR-AN syndrome, highlighting the importance of early diagnosis and a multifaceted treatment approach.

This review explores various therapeutic options for managing female hirsutism, emphasizing the effectiveness of low-dose finasteride and cyproterone acetate, but it presents no new clinical results.

This case report describes a 22-year-old male with hair casts on scalp and body hair, associated with androgenetic alopecia, also affecting his sister as pseudonits.

This study found that treatment with cyproterone acetate and ethinylestradiol in hirsute women reduced testosterone and androstenedione levels, decreased hair growth, and increased cortisol levels without changing catecholamine excretion.

This study found that m6A-circHECA enhances the differentiation of stem cells into hair follicle lineages in cashmere goats by sequestering miR-449a-5p, boosting LEF1 gene expression, and activating the Wnt/β-catenin pathway.

This review discusses idiopathic hirsutism, potential underlying mechanisms, and various therapeutic approaches without providing new clinical results, and emphasizes the need for further research on well-defined patient groups.

This study suggests that women with idiopathic hirsutism have increased 5α-reductase activity, indicated by elevated levels of 3α-diol glucuronide; further research is needed to assess its clinical biomarker potential.

This review covers the pathophysiology, diagnosis, evaluation, and treatment of hirsutism and reports no new clinical findings.

The removal of the adrenal tumor improved the patient's symptoms and reduced androgen levels, indicating successful surgery.

This review discusses causes and treatments for hirsutism in women and reports no new clinical results.

This study found that the mammalian Hr protein can interact with the p53 pathway by binding to a specific p53 response element, influencing the regulation of genes involved in cell cycle control.

This case study reported a 40-year-old woman developing Cushing Syndrome months after a single intraarticular injection of Triamcinolone Acetonide, highlighting the potential long-term effects of corticosteroid exposure and the importance of awareness about these risks for clinicians and patients.

This article discusses the first international certification examination by the American Board of Hair Restoration Surgery, with no new research findings reported.

This study concluded that polycystic ovary syndrome is the most common cause of hirsutism, with significant correlations between PCOS, insulin resistance, and BMI among affected women.

This review highlights that idiopathic hirsutism is characterized by local hyperandrogenization affecting hair growth, without other signs of hyperandrogenism, and shows no new results; racial differences in prevalence are noted but not in androgenic steroids.

This study found that a histochemical stain using 4-dimethyl-aminocinnamaldehyde effectively distinguishes between plucked anagen and telogen hairs by causing the root ends of anagen hairs to develop a red color.

This study found that ethinylestradiol and high-dose cyproterone acetate significantly reduced hirsutism scores and were effective for treating acne and alopecia in women with hyperandrogenism.

In this study, a photographic scale and questionnaire revealed that extensive central scalp hair loss was observed in 5.6% of African American women, with an association to a history of tinea capitis.
