This study found that trilostane was effective in resolving symptoms such as polyuria and polydipsia in many dogs with pituitary-dependent hyperadrenocorticism, with significant hormone level reductions observed.

The document concludes that using LC-MS/MS for measuring androgens is more accurate than older methods, but it needs careful validation and standardized references to be most effective.

This study observed that testosterone concentrations in hair segments show some stability over time, but are influenced by factors like sebum integration, hair washing frequency, and individual hair growth rates.

This study suggests that hepatocellular carcinoma in cirrhotic men is associated with altered sex-steroid metabolism, indicated by lower testosterone and 5 alpha-dihydrotestosterone levels compared to cirrhosis alone.

This study in Saudi female patients with hyperprolactinemia found that pituitary imaging is often indicated due to a high prevalence of pituitary anomalies, with prolactin levels showing moderate accuracy in predicting adenomas and a suggested cutoff level of >38.71 ng/mL for diagnosis.

This article discusses the role of human hair follicles in neuroendocrinology and suggests potential new therapeutic targets by examining how neuromediators influence hair growth, pigmentation, and stem cell biology in organ cultures.

Amenorrhea is when a woman doesn't have periods, with primary amenorrhea starting by age 15 or within five years of breast development, and secondary amenorrhea when periods stop for three months. It affects 3-4% of women not pregnant, breastfeeding, or in menopause, mainly due to polycystic ovary syndrome, hypothalamic amenorrhea, hyperprolactinemia, and ovarian failure.

The document concludes that sex hormones are crucial for mammalian reproduction, health, and behavior, and require more research for therapeutic use.

The document concludes that dermatology training and grading scales need to better represent dark-skinned individuals to improve diagnosis and assessment of skin conditions.

In this study, researchers identified a novel genetic variant in the NR3C1 gene in a mother and her son that predicts a truncated protein, leading to glucocorticoid resistance syndrome with mild hyperandrogenic features, although no clear genotype-phenotype correlation has been established.

This article reviews the use of hair cortisol concentration as a biomarker to assess long-term stress in both animals and humans, but it reports no new experimental results.

This review discusses recent data on the use of anabolic-androgenic steroids and other steroid compounds and reports no new clinical results.

Seborrhea in Parkinson's disease may be linked to hormones, not autonomic impairment.

This article discusses the importance of specialized skill in hair restoration surgery and emphasizes the potential impact of both surgeon and assistant errors on the success of the procedure; it reports no new results.

This review analyzes how androgens impact sexual desire and reproductive behaviors, emphasizing molecular interactions, but provides no new clinical results.

This review discusses how skin lesions and haircoat changes in adult horses can indicate systemic diseases, emphasizing the need for veterinary evaluation, and reports no new clinical findings.

This article discusses the systematic diagnostic evaluation of secondary amenorrhea and provides guidance for referral considerations; it reports no new research findings.

The conclusion is that different types of hair loss in dogs and cats can be cosmetic or serious, and affected animals should not be bred.

In this study, researchers identified novel LMNA mutations in patients with atypical progeroid syndrome, revealing clinical features distinct from other similar disorders, but unrelated to mutant prelamin A accumulation.

Oestrogen and thyrotropin-releasing hormone affect prolactin and its receptor in human skin and hair, suggesting new treatment options for related conditions.

This study investigated cutaneous manifestations in thyroid disorder patients, finding that hypothyroid patients commonly experienced dry skin (67.83%) while warm skin (93.3%) and increased sweating prevailed in hyperthyroid patients, with urticaria being the most common autoimmune association among both groups.

This study suggests that ultrasound and color Doppler analyses may enhance the differential diagnosis of GnRH-dependent precocious puberty in girls with premature breast development or pubic hair growth.
