This source provides a comprehensive overview of amenorrhea, detailing its classification, potential causes such as hormonal imbalances and structural abnormalities, and the various management strategies including hormone therapy and lifestyle modifications tailored to its underlying causes.

This study found that haploinsufficiency of SPINK5 can lead to Netherton syndrome when a single null mutation combines with homozygous G1258A polymorphisms, suggesting it acts as a genuine mutation affecting LEKTI function.

This study found that patients with hypothyroidism and hair loss exhibited significant differences in dermoscopic findings, including hair shaft abnormalities and vascular changes, compared to euthyroid individuals.

This review discusses the role of zebrafish as a model for studying human hereditary pigmentary disorders and reports no new experimental results, emphasizing their genetic similarities and the genetic tools available.

This study reported the first known case of tertiary hypothyroidism in a dog, diagnosed after a Labrador treated for hyperadrenocorticism presented with related symptoms and an MRI-revealed pituitary mass.

This study found that low-dose radioactive iodine therapy for hyperthyroidism and thyroid cancer produced short-term adverse effects like loss of taste, xerostomia, and hair loss, which were self-limiting.

This study reported that treating alopecia patients with thyroxin tablets to reduce TSH levels, along with hair growth therapies, improved hair follicle growth and hair structure.

This review discusses the uncertain role of immune factors, particularly autoantibodies, in the development of alopecia areata and emphasizes that identifying key autoantigens could lead to targeted immunotherapies.

This study found that a specific mutation in the mouse RXRalpha gene significantly impacts immune responses and causes hair loss and skin cysts.

This study found that increased serum testosterone and dehydroepiandrosterone sulphate levels may serve as diagnostic markers for seborrheic meibomian gland dysfunction in both genders.

This case report describes a 36-year-old female patient with panhypopituitarism, experiencing severe adrenal insufficiency and thyroid hormone deficiency, which led to electrolyte imbalance, QT interval prolongation, and ventricular tachycardia; treatment stabilized her condition, underscoring the importance of hormonal evaluation in arrhythmia assessment.

This veterinary case study of a dog with myxedema coma found clinical and pathologic changes including severe thyroid atrophy and marked atherosclerosis consistent with the diagnosis.

This research highlights the importance of considering hypothyroidism in dogs for early diagnosis and treatment to prevent potentially life-threatening complications, given its relative commonality compared to other diseases causing dermatological changes or obesity in these animals.

This review discusses the enigmatic nature of frontal fibrosing alopecia and reports no clinical results; the authors stress the need for further research.

In this study, subclinical hypothyroidism in women with PCOS was linked to changes in the thyroid-prolactin axis and a lack of correlation between TSH and AMH, while gonadotropin levels and ovarian morphology remained unaffected, indicating the need for further prospective research.

Among Japanese patients with generalized vitiligo, this study found a genetic susceptibility to autoimmune diseases, particularly autoimmune thyroid disease, within families.

In this study, inducible whole-body Acly-knockout mice revealed that ACLY is essential for skin homeostasis, as its deficiency led to increased sebum production and skin abnormalities, indicating a vital role for cytosolic acetyl-CoA synthesis in preserving skin barrier integrity and systemic lipid regulation.

In this study involving rats with letrozole-induced polycystic ovary syndrome, Agaricus subrufescens significantly reduced blood glucose, total cholesterol, testosterone levels, and renal markers, suggesting its potential protective effects on both metabolic and reproductive parameters.

This study reviews current treatments for PCOS and evaluates Tirzepatide as a potential option for its management, suggesting possible benefits for those with obesity and metabolic syndrome but not for those of normal weight.

This case report highlights the diagnostic challenges of thyroid storm, emphasizing the importance of a thorough history and review of systems to differentiate it from other conditions.

The document concludes that inflammation markers can be used in diabetes, vitamin D3 affects immune pathways, hyperthyroidism changes hormone levels, androgen levels help diagnose Adrenocortical Carcinoma, erectile dysfunction is linked to diabetes, hypogonadism is common in HIV-infected males, and hormones can be biomarkers for various conditions.

This review discusses telogen effluvium, including its triggers, clinical presentations, and management options, and does not report new research findings, emphasizing the need for identification and exclusion of underlying causes.

In this study, researchers in Basrah, Iraq, observed that iodine deficiency in cross-breed goat kids led to goiter, slow growth, and various biochemical changes, including increased TSH and hypercholesterolemia, suggesting the need for improved maternal diet to reduce these issues and associated mortality risks.

This review discusses the causes and management of hirsutism, recommending low-dose oral contraceptives with flutamide over cyproterone-containing preparations, but reports no new clinical findings.

This study by a panel of 13 clinicians led to 22 consensus statements recommending approaches for diagnosing scarring and nonscarring alopecias, suggesting scalp biopsy for suspected scarring alopecias and specific serologic tests for nonscarring types like alopecia areata based on clinical presentation.

This case study describes a previously unknown association of the PIBIDS complex with autoimmune thyroiditis and autoimmune hemolytic anemia in a five-year-old Indian child.

This review explores the diverse physiological roles of the vitamin D endocrine system, discussing current research on receptor structure, transcription details, murine models, and alternative receptors, but reports no new findings.

This review explores the potential impact of hormonal changes during aging on benign prostate hyperplasia-related urinary symptoms and metabolic syndrome, highlighting the hypothesis of a male PCOS-equivalent but reports no new clinical results.

This study found that patients with RASopathies have lower serum IgA and CD8 levels compared to controls, indicating a potential risk for developing autoimmune disorders.

This review discusses the expression of circadian genes in hair follicles and their potential for monitoring circadian-rhythm-related conditions, reporting no clinical results; the authors suggest combining hair sampling with other assessments for better insight.
