This study found that distinct isoenzymes of 3 beta-hydroxysteroid dehydrogenase are expressed in human adrenals and gonads compared to the placenta and skin.

This review discusses recent insights into Birt–Hogg–Dube syndrome, including the functions of the FLCN gene and clinical recommendations for screening and treatment, but it reports no new experimental results.

This case report illustrates how SNP array testing helped identify a DCAF17 mutation linked to Woodhouse-Sakati syndrome in consanguineous Qatari siblings with shared features including alopecia and hypogonadotropic hypogonadism.

This article provides a guideline for physicians on managing hair disorders, including recent developments and clinical practice guidelines, but it reports no new research findings.

This study found that while DP concentrations in dust were higher in male dormitories, DP in hair was higher in females, suggesting differing metabolism between genders and that hair DP mainly originates internally.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

This study found that hypoxia increases the proliferation of dermal papilla cells and highlighted the important role of lactate dehydrogenase in this process.

This study found that home-use diphenylcyclopropenone (H-DPCP) is a cost-effective alternative to office-use for severe alopecia areata, showing similar effectiveness with reduced costs.

This study reports a case of GGCX syndrome in a 55-year-old Japanese male, characterized by PXE-like symptoms and coagulation deficiency, with an unreported phenotype of possible spinocerebellar degeneration.

This study identified a homozygous frameshift mutation in the HOXC13 gene associated with pure hair and nail ectodermal dysplasia in a consanguineous Syrian family, suggesting crucial roles for HOXC13 in hair and nail development.

This study presents a new approach to automatically remove hair artifacts from dermoscopic images, which reportedly performed well compared to existing methods like DullRazor using the PH2 datasets.

Certain enzymes react strongly with some hormones in rat skin during hair growth, mainly in sebaceous glands and hair sheaths.

This study found that HIF-P4H-2 function in FoxD1-lineage cells is crucial for normal hair follicle development and homeostasis in mice, implicating disrupted HIF, TGF-β, and Notch signaling pathways in associated defects.

This study found that hair cortisol concentrations in mother-daughter pairs are a potential biomarker for cortisol responses to chronic stress, with daughter-mother similarities affected by parenting styles and children's symptoms.

In this case study, researchers detailed two Saudi cases of the ultra-rare Trichohepatoneurodevelopmental syndrome, identifying pathogenic variants in the CCDC47 gene and reinforcing a strong gene-disease association, which helps clarify the disorder's clinical features and genetic mutations.

In this study, researchers created a comprehensive transcriptome map of human hair follicle compartments, identifying compartment-specific genes and providing a resource for potential therapeutic interventions.

This study created a humanized mouse model of hereditary vitamin D-resistant rickets that lacks alopecia, indicating the mutant receptor's potential to explore the syndrome's characteristics beyond vitamin D binding.

This study found that most hair shaft abnormalities can be accurately diagnosed using a handheld dermoscope in a clinical setting.

This handbook of dermatology provides a comprehensive practical manual for dermatologists, but reports no new research findings.

This review summarizes recent research and patents on 17β-HSD3, 17β-HSD5, and 3α-HSD3 inhibitors, suggesting their potential in treating androgen-dependent diseases, but reports no new clinical results.

This piece reflects on the past year of editing the Assistants' Corner and presents no new research findings.

In this retrospective study of eight Saudi children with hereditary vitamin D resistant rickets, researchers observed that adjunctive cinacalcet appeared safe and showed initial promise in improving serum PTH levels, though further investigation is needed to confirm its efficacy.

This study found that diphencyprone is an effective and safe treatment for extensive alopecia areata, especially with long-term therapy and maintenance to reduce relapse risk.

This research identified nonclassic 21-hydroxylase deficiency as the most common genetic autosomal recessive disorder in humans, particularly among certain ethnic groups, and found that treatment effectively reverses symptoms within months.

This article reviews congenital adrenal hyperplasia, a group of rare genetic disorders affecting steroid synthesis, and highlights the need for specific therapy and ongoing monitoring, but reports no new clinical findings.

This case report presents a rare subtype of hypomyelinating leukodystrophy linked to a PYCR2 gene mutation, emphasizing exome sequencing's value in diagnosing undiagnosed childhood HLDs with atypical symptoms.

This study found that stabilizing HIF1A in hair follicle cells promoted a shift to glycolysis, potentially reducing oxidative stress and promoting hair growth, particularly in balding dermal papilla cells.

This study suggests that D2O increases hair length in nude mice by extending the hair cycle duration, particularly the hair-existing phase, which is associated with increased mast cell density.

This article summarizes a meeting of the American Board of Hair Restoration Surgery's Board of Directors to discuss future plans, but does not report new experimental results.
