This case report describes a unilateral contact dermatitis caused by shoe dye containing 4-aminoazobenzene, which was confirmed with patch testing, highlighting its atypical presentation.

This report describes a rare case of elevated serum DHEAS levels in a postmenopausal woman, linked to an ovarian sex cord-stromal tumor rather than the adrenal glands, challenging common assumptions about androgen sources.

The researchers investigated a Maine Coon cat with suspected classical Ehlers-Danlos Syndrome and discovered a heterozygous deletion in the COL5A1 gene, underscoring the value of whole-genome sequencing for precise veterinary diagnostics.

This study conducted a detailed examination of Terminalia arjuna flowers, suggesting their potential use in establishing botanical standards for identification and standardization in Ayurvedic medicine.

More research is needed to understand hair and scalp disorders in children with skin of color.

In this study, the ablation of Tet2/Tet3 genes in mouse skin epithelial cells led to altered hair shape and length, highlighting their role in regulating hair follicle gene expression and chromatin structure.

This article discusses the factors involved in optimizing laser hair removal, emphasizing patient selection, laser safety, and understanding laser–tissue interactions, but presents no new clinical findings.

This study found that active BMP signaling prevents epithelial stem cell activation and expansion in hair follicles, while its inhibition leads to HF stem/progenitor cell overproduction and matricomas.

This study found that keratin expression patterns vary within nail unit structures, with the nail matrix uniquely expressing the acidic hair-type keratin Ha1.

This study found that normal mode ruby laser treatment for hirsutism is well tolerated and results in significant hair count reduction for at least six months, with multiple treatments offering greater effects.

In this study, researchers found that loss of OGG1 in a mouse model of systemic lupus erythematosus increased IFN-driven immune responses and aggravated skin lesions, suggesting a protective role for OGG1 in SLE skin disease.

This study found that in vitro treatments with 5alpha-reductase inhibitors and androgen receptor antagonists strongly stimulate VEGF expression in dermal papilla cells.

This review examines the devices, mechanisms, risks, side effects, and regulatory differences in laser hair removal, particularly highlighting the lack of regulation in South Africa and its implications for patient safety.

Metformin helps manage diabetes, PCOS, and weight in kids but needs more research for long-term safety.

This study found that keratinocytes show increased expression of the TGF-β system and collagen type I with age, suggesting a heightened profibrotic response during skin differentiation associated with scarring.

This study found that deleting podoplanin in mouse keratinocytes promoted hair follicle growth during regeneration, suggesting it may regulate hair cycling pathways that could aid in treating hair loss conditions.

Keratin proteins in epithelial cells are dynamic and crucial for cell processes and disease understanding.

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This study reported that atypical variants of alopecia areata made up less than 25% of all cases in their specialized trichology unit, suggesting a potential selection bias.

This review discusses the complexities of hidradenitis suppurativa pathogenesis, highlighting issues with Notch signaling, immune dysregulation, and the role of keratinocytes and ECM, but reports no new clinical results.

This study reported that injecting monofilament threads into the scalp significantly improved hair count and hair mass index in women with female pattern hair loss, with most participants noticing substantial improvements in hair characteristics compared to a placebo.

This study concluded that the follicular route is a significant pathway for delivering gentamicin through the skin, as demonstrated by higher drug permeation in non-plugged pig's ear skin compared to plugged skin.

This study found that hyperbaric oxygen treatment in rats led to structural changes in epidermis and dermis, including decreased E-cadherin expression and increased connective tissue.

In this study, Urtica dioica extract was found to significantly downregulate 5-alpha-reductase type II gene expression in skin cells, suggesting potential usefulness against androgenic skin diseases.

This article discusses primary cicatricial alopecia, highlighting the need for early and precise diagnosis to effectively manage and treat these complex inflammatory hair disorders, but presents no new clinical results.

This study observed that beef cattle with certain prolactin receptor gene mutations, known as slick mutations, demonstrated improved post-weaning growth and temperature regulation in a hot, humid climate compared to other genotypes, suggesting genotype influences growth efficiency and heat tolerance.

This study found that certain proteins linked to immune suppression and melanogenesis are associated with repigmentation in vitiligo patients undergoing standard treatment, suggesting these proteins and their pathways play roles distinct from merely reversing skin lesions.

Tissue-engineered skin substitutes can model junctional epidermolysis bullosa and may help develop gene therapy.

Changes in hair follicle structure may help diagnose and monitor alopecia.

This study developed a deep learning-based tool to quantify individual hair fibers in mice, revealing distinct hair phenotypes linked to hormonal, genetic, and age-related factors, and suggesting its potential for new diagnostic methods through hair analysis.
