This study examined the complex morphology of the cornified claw sheath in domesticated cats, uncovering structures and growth patterns that help maintain sharp claw tips essential for climbing and prey capture.

This retrospective study observed that hair grafting in burn and postskin graft scars, which preserve deeper skin layers, had more favorable outcomes than in scars extending to the subcutaneous layer.

This article discusses dissecting cellulitis of the scalp, an uncommon hair condition, and reports no new clinical results; recent terminology adjustments are noted for potential overlaps with other follicular diseases.

In this case report, researchers observed that a malnourished male patient developed pseudoglucagonoma syndrome, characterized by necrolytic migratory erythema and diffuse hair loss, following Frey's surgery, which rapidly improved with enhanced nutrition.

This study identified a large deletion in the desmoglein 4 gene as the genetic basis of the Iffa Credo "hairless" rat's skin phenotype, linking it to lanceolate hair mutations.

This chapter reviews various hair disorders, focusing on androgenetic and scarring alopecias, and discusses management strategies, but presents no new research findings.

This study found that deleting the CD98hc protein in mouse skin impairs wound healing and homeostasis, resembling aging effects, due to disrupted integrin signaling pathways.

This case report detailed two instances of plica polonica, an acquired hair matte condition, attributing it to factors like drug effects and hair care neglect, but emphasized not labeling affected patients as unable to self-care.

This study found that fibrosis-associated trochanters in central centrifugal cicatricial alopecia are enriched with hair follicle stem cells and may indicate a disrupted stem cell niche contributing to scarring.

This article describes a case of feline exfoliative dermatitis associated with a suspected thymoma, diagnosed using histopathology and imaging, and does not report new research findings beyond the case description.

This research detailed a single-cell atlas showing dynamic hair follicle stem cell states associated with the hair cycle during aging in mice, highlighting differences in chromatin landscape linked to stem cell differentiation and quiescence, and providing a foundation for future exploration of aging reversal.

In this study, researchers found that patients with Friedreich's ataxia exhibited more pronounced ultra-structural hair alterations compared to carriers, likely due to oxidative stress related to deficient frataxin expression.

This report describes a successful case where repeated autologous lipostructure followed by hair transplantation improved scarring alopecia in a patient with morphea en coup de sabre, suggesting potential benefits from this combined approach.

This study demonstrated that mitochondrial function in keratinocytes is crucial for maintaining skin homeostasis and hair follicle development, as its impairment led to disrupted hair morphogenesis and early death in mice.

This article presents a dermatological case involving a 36-year-old woman with ambiguous alopecia, evaluated using videodermatoscopy, but it reports no new research findings or clinical outcomes.

This case report describes a woman with an unusual presentation of tinea capitis, noting diagnostic challenges as initial examinations found no mycelium or spores.

This study examined the morphological variations of terminal hair from different body regions of a Caucasian male, finding notable differences in diameter and features like "steak-boning" in specific hair types.

This article reviews surgical approaches for correcting cicatricial alopecia, highlighting the need for careful assessment of scar stability and ongoing medical treatment before and after hair restoration, but reports no new clinical results.

This study identified distinct and diverse fibroblast populations in female scalp cells that lose their signature and identity with age, highlighting significant age-related changes, such as increased fibrosis, DNA damage, and senescence, which may affect scalp dermal support for healthy hair follicles.

This study found that androgenetic alopecia may involve a defect in the conversion of hair follicle stem cells to progenitor cells, as demonstrated by a reduced presence of progenitor cells in bald scalp samples.

This case report describes a 17-month-old girl with a history of itching skin, hair thinning, swelling, growth delay, anemia, and protein deficiency amidst potential food allergies and other health issues.

This study classified scars in discoid lupus erythematosus patients into six types based on anatomical location and morphology, suggesting early identification might influence more aggressive treatment strategies.

This study describes Pseudopelade of Brocq as a rare and enigmatic scarring alopecia characterized by irregular hair loss patterns on the scalp, requiring exclusion of other conditions like lichen planopilaris and discoid lupus erythematosus for a specific diagnosis.

This case report describes a patient with pseudopelade affecting both the scalp and beard area, highlighting the unusual presentation of a rare hair disorder.

In this study using a mouse model of Pemphigus vulgaris, researchers found that loss of desmoglein 3 adhesion in hair follicle stem cells triggers a regenerative program restoring stem cell function, requiring Hedgehog pathway suppression.

This study reports an unusual finding of plucked anagen hairs with intact hair papilla and connective tissue sheath in various scalp disorders, suggesting further documentation is needed.

This study found that hair follicle micro-graft transplantation significantly improved scar remodeling outcomes in 40 patients, with greater reductions in scar volume, lower scar scores, and enhanced skin characteristics compared to punch excision alone, potentially due to activation of the PI3K-AKT pathway.

In this study of elderly patients at an Indian medical center, researchers found that xerosis was the most common physiological skin change and pruritus was the most frequent complaint.

Cathepsin L deficiency causes hair and skin issues in mice.

This study observed that orange spots and dystrophic hairs on trichoscopy may aid in diagnosing scalp sarcoidosis.
