This study used single-cell and spatial transcriptomic profiling to identify specific molecular markers in human follicular dermal papilla cells, enhancing understanding of their role in hair follicle development.

This review discusses perceptions and side effects of depot medroxyprogesterone acetate and emphasizes the importance of educating teens to enhance compliance; it reports no new clinical findings.

This case report describes an individual who developed both localized hypertrichosis and ipsilateral dyshidrotic dermatitis following multiple fractures and cast application, with symptom resolution similar to when these conditions occur independently.

Hair cortisol concentration partly reflects HPA axis regulation but doesn't capture all its complexities.

This study found that a daily dose of 50 mg DHEA only slightly increased the urinary testosterone/epitestosterone ratio for a short period, without exceeding the IOC's acceptable limit.

This study mapped a spontaneous mouse hair mutation, "hague," to keratin genes on chromosome 15 but found no gene mutations in hague mice.

This study found that plantar dermis matrix homogenate can partially restore the regenerative capacity of hair follicles impaired in culture, with CTHRC1 playing a critical role in this process.

This study found that Hoxc13-/- rabbits exhibit complete hair loss on the head and dorsum, providing a potential model for understanding human ECTD-9 and related dermatological conditions.

This study identified a new cis-regulatory element in the mouse Hr gene that influences its expression in skin and brain cells, highlighting a complex molecular network involved in hair follicle formation.

This review discusses the categorization of hair loss and increased hair density disorders related to systemic diseases and reports no clinical results, emphasizing the potential diagnostic value of history, physical examination, and histopathologic data.

This quiz article provides a series of dermatological diagnosis questions based on a Journal of Investigative Dermatology article and includes explanations but reports no original research findings.

This study found that Dendrobium candidum polysaccharides might promote hair growth in mice, potentially by increasing VEGF mRNA expression.

Hyperandrogenism is diagnosed using clinical signs, lab tests, and imaging.

This article illustrates various hair shaft defects and suggests that dermatologists can diagnose most of them using light microscopy and polarization without needing advanced imaging techniques.

This study of a Yorkshire dog with chronic dermatological alterations highlights the diagnostic importance of combining complementary laboratory tests like histopathology and serum biochemistry with clinical examination.

This review discusses the genetics and variable phenotypic expression of nonclassic congenital adrenal hyperplasia, and reports no new clinical results; the authors call for further research on long-term health impacts and treatment strategies.

This review discusses a quiz related to seborrheic dermatitis diagnosis and key findings from a previous study, but reports no new clinical results.

This study suggests that impaired VDR signaling in mice leads to dysregulated Ddit4 expression, impacting hair cycle progression and wound healing.

This study suggested that differences in hair follicle development, indicated by the frequency of underdeveloped hairs, significantly contribute to the variation in hair loss severity among Japanese individuals with the LIPH c.736T>A mutation.

This case report describes a patient with alopecia areata treated with diphencyprone, who experienced both successful hair regrowth and later intense hair shedding, compatible with telogen effluvium, suggesting a possible link between contact dermatitis treatments and telogen effluvium onset.

This systematic review found that digital health interventions may improve quality of life for dermatology patients, especially through telemedicine, which often matched or exceeded in-person care. However, the evidence is limited by study variability and short follow-up periods.

This study found that the truncated hHb1-DeltaN transcript in breast cancer cells is produced by a cryptic intron promoter and responds to DNA demethylation, potentially altering cancer cell adhesion.

In this clinical case report, a man with Birt Hogg Dube syndrome presented with parathyroid cancer, the first such case according to the authors, highlighting a potential link between Folliculin gene mutations and parathyroid cancer development.

This study found that human hair follicle dermal papilla cells cultivated as 3D spheroids in hexanoyl glycol chitosan-coated dishes formed hair-like structures, with minoxidil enhancing growth, and successfully integrated into artificial skin models, suggesting advancements for hair loss treatments and skin restoration therapies.

This study developed and tested a new algorithm for analyzing coat and skin coloration in laboratory animals, using digital images and hierarchical color clustering, which effectively quantified color proportions and tracked changes over time without specialized software.

This discussion highlights the genetic and phenotypic variability in inherited hair disorders and emphasizes the importance of accurate diagnosis due to potential systemic manifestations; no new clinical results are reported.

This review covers the pathophysiology, diagnosis, and treatment of nonclassic congenital adrenal hyperplasia due to P450c21, but it reports no new clinical results.
