This study found that vitamin D deficiency in patients with alopecia areata was associated with greater disease severity and longer duration, but not with disease pattern or vitamin D receptor expression.

This study suggests that lower serum and tissue vitamin D receptor levels in alopecia areata and androgenetic alopecia patients may play a role in the pathogenesis of these hair diseases.

This study found that despite carrying an activating Hras mutation, hair follicle stem cells integrate into normal skin without causing tumors, unlike similar mutations in the epidermis, suggesting unique tumor-suppressing mechanisms in hair follicles.

This review explores the role of neutrophil recruitment in the inflammation seen in hidradenitis suppurativa and emphasizes potential therapeutic targets within these pathways, but it reports no new clinical results.

This study found that skin-resident Treg cells regulate hair follicle stem cell proliferation and differentiation through the Jag1-Notch signaling pathway, influencing hair regeneration.

This review discusses various chemical and instrumental methods for determining macrolides and reports no new experimental results.

This study found no significant association between vitamin D levels and alopecia areata in patients when gender was accounted for, but vitamin D levels were lower in patients with nail involvement.

This study found that Thy1+ keratinocytes in the basal layer of the interfollicular epidermis play a crucial role in epidermal homeostasis and wound repair, with their ablation impairing these processes.

This article reviews hair and nail disorders in children, emphasizing their prevalence, congenital and acquired origins, and the diagnostic challenges compared to treatment, but reports no new clinical results.

In this study, re-activating SOX9 in adult epidermal stem cells led to a fate switch towards hair follicle stem cell identity, with altered chromatin dynamics and oncogenic activation, contributing insights into developmental processes and cancer pathways.

This study found that mutations in the TULP3 gene are associated with progressive degeneration of the liver, kidney, and heart in adults, highlighting the importance of early detection and management.

This letter reports on the impact wigs may have on the perceived quality of life in patients with androgenetic alopecia.

In this study, researchers identified loss of function variants in the HR gene as likely causes of the distinct roaning hair coat seen in lykoi cats.

In this open-label trial, tofacitinib showed dramatic clinical responses in most patients with moderate-to-severe alopecia areata, supporting further research into JAK inhibitors for this condition.

In this case report, the authors identified giant cell arteritis as the underlying cause of bitemporal hair loss and scalp tenderness in a 70-year-old woman, initially misdiagnosed as age-related symptoms.

This study describes the positive effects of the JAK inhibitor ruxolitinib in treating autoimmune manifestations in three patients with autoimmune polyendocrine syndrome type-1 over a period of at least 30 months, with excellent tolerance and no adverse events observed.

In this study, researchers found that specific mutations in iRhom2 in mice lead to skin and hair abnormalities which depend on the presence of the protein ADAM17, suggesting a complex role for iRhom2 in tissue development and potential implications for treating tylosis with oesophageal cancer.

The editor suggests removing "race" and "ethnicity" from dermatology and creating tools to objectively assess skin color and hair texture.

This essay discusses the author's views on establishing a successful academic laboratory and reports no new research findings.

This case study describes a Lop male rabbit with Malassezia-associated dermatitis, initially treated with griseofulvin but requiring ketoconazole for complete recovery after recurrence.

This study found that vitamin D regulates cholesterol metabolism and may influence prostate cancer development through mechanisms affecting prostate cell growth and sex hormone metabolism.

This case study reports a 15-year-old girl from a visceral leishmaniasis-endemic area in Greece presenting with various symptoms, including high fever, morning joint pain, and blood in urine, eventually leading to findings like rash, anemia, and kidney issues. Results are not detailed in this abstract.

This study found a widespread vitamin D deficiency among medical laboratory visitors in Misurata City, with 80.42% of females and 19.57% of males affected, and higher deficiency rates during winter and spring, particularly in individuals aged 35–45.

In this study, researchers observed that inhibiting myosin light chain kinase in hair cells reduced stiffness and oscillation in bullfrog hair bundles and increased hearing thresholds in mice.

In this study, researchers assessed vitamin D3 levels in adolescents, finding a suboptimal average of 22.00 ng/ml, and demonstrated that supplementing with 1000 IU/day of vitamin D3 significantly raised levels and improved physical and mental potential over two months.

This study describes the case of a 22-year-old female with alopecia areata linked to vitamin D deficiency, highlighting the importance of early diagnosis and management of deficiency to prevent broader health issues.

This study describes the use of a genetically engineered mouse model, mTurquoise2-Col4a1, to fluorescently label collagen IV and observe basement membrane dynamics during skin development, revealing its stability and pliability during rapid growth phases.

This case report describes two boys aged 8 and 10 with loose anagen hair syndrome who experienced successful hair regrowth using topical minoxidil 2% solution, suggesting it may be an effective initial treatment option for severe cases of this condition.

This case report describes a rare instance of familial congenital atrichia in a 16-year-old girl, possibly involving a genetic component, as both her parents exhibit similar clinical features.

PDE inhibitors, especially PDE4 inhibitors like apremilast, are effective for certain inflammatory skin conditions but have side effects and can be costly.
