Amenorrhea, or the absence of periods, should be evaluated by age 15 or within five years of early breast development, and is most commonly caused by conditions like polycystic ovary syndrome and hypothalamic amenorrhea.

Skin conditions can signal heart issues, highlighting the need for integrated care.

This case report describes a 14-year-old female patient with both Systemic Lupus Erythematosus and Diabetes Mellitus, highlighting the rarity of this combination and the importance of thorough evaluation to accurately diagnose and predict the clinical course of the disease.

Atopic dermatitis may have genetic causes and can be treated with pharmacologic methods, glycerin creams, and controlling Staphylococcus aureus colonization.

Hormonal differences affect male pattern baldness.

In this study, the researchers developed and evaluated eco-friendly poly-herbal soap strips using plant extracts from Lantana camara, Moringa Oleifera, and Corn silk, finding that the strips exhibited superior physicochemical properties and significant anti-fungal activity compared to conventional anti-fungal soaps.

This article discusses vaccination coverage for BCG, Polio, and Hepatitis B in Juiz de Fora using SUS data and reports no new results; the authors aim to hypothesize reasons for coverage variation.

This study discusses how dermatological issues in athletes can arise from or be exacerbated by mechanical trauma, infections, and environmental factors, highlighting the importance of thorough history and examination to differentiate these from other skin conditions.

This study investigated the relationship between lichen planus and dyslipidemia but did not report any clinical findings.

This study found that stimulating the olfactory receptor OR2AT4 in human hair follicles with a synthetic sandalwood odorant promotes hair growth ex vivo by decreasing apoptosis and increasing IGF-1 production.

This study found that silencing clock genes BMAL1 or PER1 in human hair follicles increased melanin content and melanocyte activity, suggesting these genes influence pigmentation.

This study found that thyrotropin-releasing hormone (TRH) acts as a potent stimulator of hair growth in human scalp hair follicles, promoting elongation and prolonging the anagen phase.

This study found that prolactin is a key regulator of keratin expression in human hair follicles, enhancing specific keratin types and influencing epithelial stem cell-associated keratins.

This study suggests that cerebrospinal fluid levels of the neurosteroids allopregnanolone and pregnanolone correlate negatively with PTSD and negative mood symptoms, with potential sex-specific differences in synthesis enzyme blocks.

This article discusses the role of neurohormones and neuropeptides in hair follicle pigmentation and outlines promising neuroendocrinological strategies to address greying and damage, but reports no new clinical results.

This study found that bimatoprost stimulated hair growth in both human scalp follicle cultures and mouse pelage in vivo, suggesting it might offer a promising treatment for scalp alopecias.

This study found that JunB, a transcription factor, is crucial for maintaining epidermal-pilosebaceous stem cell homeostasis by regulating progenitor cell behavior and preventing sebaceous gland dysfunction.

This study found that autophagy plays a novel role in human hair growth, with altered autophagic flux during hair development phases influencing hair follicle behavior in a preclinical model.

This review explores the potential (neuro-)endocrine influences on hair follicle epithelial stem cell biology and emphasizes the need for more systematic research, but it provides no new empirical results.

This review discusses immunohistological and immunofluorescent methods for studying the human hair follicle cell cycle, reporting no new results, and suggests its potential for advancing cell cycle research.

This review highlights that while dexamethasone may reduce mortality in severe COVID-19, no other drugs have proven effectiveness for treatment, emphasizing the need for clinical trials of existing medications.

In this study using a rat model, discontinuing dutasteride improved some relaxant responses but did not fully restore erectile function, indicating a potential time-dependent detriment of the drug.

This review discusses how neuroendocrine pathways influence keratin regulation in human skin and hair follicles and suggests these pathways as potential targets for new treatments of skin disorders, but reports no clinical results.

This review discusses persistent sexual and nonsexual adverse effects of the 5α-reductase inhibitor finasteride in younger men, including erectile dysfunction, low libido, and depression. It reports no new clinical results but emphasizes further research is needed.

This review highlights the potential of aromatic plants as natural antioxidants in cosmeceuticals, which may combat skin aging and promote rejuvenation by counteracting oxidative stress, offering a natural alternative to synthetic products with benefits like photoprotection and anti-wrinkle effects.

This study found that maternal sub-maintenance nutrition reduced the density and branching ratio of secondary wool follicles in Merino sheep fetuses and identified genes potentially involved in these processes.

This study suggests that miRNAs, particularly miR-195-5p, may regulate the loss of hair follicle inductivity in cultured dermal papilla cells by suppressing the Wnt/β-catenin pathway.

This review discusses various skin conditions linked with chronic kidney disease and highlights effective treatments but does not provide new clinical results.

This exploratory study found that cannabidiol (CBD) at higher concentrations may inhibit hair growth by promoting the onset of catagen in human hair follicles, while lower concentrations showed potential anti-inflammatory effects without promoting catagen.
