This case report describes the first instance of juvenile hemochromatosis type 2A associated with secondary hypothyroidism, linked to a novel mutation in the HJV gene.

This study observed significant differences in the skin microbiome between hidradenitis suppurativa patients and healthy individuals, notably with decreased β-diversity and a distinct abundance of certain bacteria in affected skin.

This study found that notch1 signaling is severely impaired in hidradenitis suppurativa patients with or without NCSTN or other gamma-secretase gene mutations, highlighting a canonical defect at the lesional tissue level.

This study found that mutations in the hairless gene in mice disrupt hair follicle integrity during catagen, leading to baldness due to disintegrating epithelial structures and loss of normal dermal papilla.

This case report highlights a family member with a confirmed diagnosis of hypotrichosis with juvenile macular dystrophy due to a CDH3 gene mutation, emphasizing the importance of genetic testing for accurate counseling.

In this study, idiopathic hirsutism was identified as the most common cause of hirsutism among the patients, followed by polycystic ovarian syndrome.

This study found that hidradenitis suppurativa significantly impaired quality of life in German patients, with severity linked to skin and certain extra-cutaneous changes, but not reduced by surgical or conventional medicamentous treatments.

This study found that 70-MHz ultrasound can detect early signs of hidradenitis suppurativa linked to severity, including hair follicle abnormalities and keratin fragmentation, aiding in diagnosis and management.

This study suggests that increased activity of the histamine synthesizing enzyme histidine decarboxylase may play a role in initiating the anagen phase of hair regrowth in mice.

In this study, researchers are constructing a comprehensive data set from 997 adult participants in Japan to develop a statistical model that explores the relationships among various health parameters, aiming to enable personalized and preventive health care interventions based on empirical data.

This study reported that heterozygosity for FHIT affects mice's susceptibility to spontaneous alopecia areata and to certain preneoplastic lesions induced by benzo[a]pyrene, but does not change how they respond to budesonide and N-acetyl-L-cysteine.

This study found that anionic HSES achieved high complexation efficiencies with various steroids, significantly enhancing their solubility, while specific β-cyclodextrin thioethers showed selective binding to testosterone and estradiol.

This study suggests that the NCSTN knockout mouse could serve as an HS animal model, with tamoxifen potentially used for gene deletion in mice.

This guideline outlines therapies for hidradenitis suppurativa/acne inversa, noting that oral tetracyclines, clindamycin, and surgical options are important for treatment, with adalimumab, secukinumab, and bimekizumab also approved.

A 4-year-old girl had a rare hair disorder affecting only part of her scalp.

This review discusses genetic mutations associated with Hutchinson-Gilford progeria syndrome and reports no clinical results; the authors emphasize the importance of cardiovascular monitoring in management.

This article discusses the formation and goals of the World Association of Hair Replacement Surgeons, focusing on the exchange of advanced hair restoration surgery techniques, without presenting new research findings.

This study found that the protein hairless acts as both a corepressor and coactivator of the vitamin D receptor, influencing gene transcription in a ligand-selective manner.

This study observed that some patients with homozygous c.736T>A mutation in LIPH may have mild hypotrichosis with long hairs in adulthood.

This study evaluated the safety and effectiveness of HASHA, a new hyaluronic acid injectable, for chin augmentation in adults with chin retrusion. HASHA significantly improved chin appearance and satisfaction over 12 months compared to controls, with only mild or moderate transient adverse events.

This study found that recombinant human HGF/SF injections altered hair follicle growth cycles and mildly promoted hair elongation in mice, depending on their hair cycle stage.

In this study, beagle dogs treated with hydrocortisone 17-butyrate 21-propionate ointment showed various toxic effects, including acne-like skin changes and organ atrophy, which returned to normal after a recovery period.

This article presents an overview of uncombable hair syndrome, emphasizing its clinical and molecular characteristics and noting systemic manifestations such as neuropsychiatric, ophthalmic, and cardiopulmonary issues.

This study found that Hedgehog-driven skin tumorigenesis is dependent on the Wnt/beta-catenin signaling pathway and suggests that targeting Wnt ligands could be a potential therapeutic strategy.

This study describes new devices, "HairMeasure" and "Scalp Zone Identifier," which offer an economical method to calculate Hair Mass Index without disposable materials.

The authors reported that 4-O-methylhonokiol decreased TGF-β1-induced cell cycle arrest and oxidative stress markers in human keratinocyte cells, suggesting a potential protective role in TGF-β1-mediated cell cycle regulation.

This study found that treatment with a GnRH agonist and estrogen and progestin replacement significantly improved hirsutism scores and hair growth rates in women with polycystic ovarian disease.

In this study, researchers found that hair follicle-derived mesenchymal stem cells, modified to overexpress extracellular matrix protein 1, significantly improved liver function and reduced liver damage in cirrhotic mice by inhibiting hepatic stellate cell activation and TGF-β/Smad signaling.

This study found that the HairCheck® device, demonstrating high correlation between its Hair Mass Index and hair characteristics such as strand number and diameter, may be an effective tool for assessing hair mass changes in alopecia patients.
