This review discusses the challenges in identifying specific hair follicle antigens involved in initiating alopecia areata and highlights the need for further research to understand its etiopathogenesis, reporting no new results.

In this study, topical phenylephrine significantly reduced hair shedding and increased the force needed to pluck hair in women undergoing cosmetic procedures, suggesting its potential utility for traction alopecia.

In this case report, a 9-year-old horse was diagnosed with alopecia areata contributing to Malassezia dermatitis, involving lymphocyte infiltration and symptoms consistent with yeast presence.

This chapter reviews traction alopecia, discusses its clinical presentation and severity grading, and reports no new clinical results; the authors highlight controversies in its treatment and prevention strategies.

This study reports that KRTAP-like proteins, which resemble keratin-associated proteins found in mammals, are also present in the cornified teeth of various lamprey species, suggesting these proteins may serve similar functions in skin appendages across different vertebrates despite independent evolutionary origins.

This study suggests that congenital atrichia with papular lesions may be more common than previously thought and proposes diagnostic criteria including the observation of hypopigmented whitish streaks on the scalp.

This case report highlighted two atypical childhood alopecia cases: congenital atrichia without papules and Bjornstad syndrome with alopecia areata; emphasizing diagnostic challenges, notably the absence of keratotic papules usually associated with congenital atrichia and the presence of alopecia areata in Bjornstad syndrome.

In this case report, trichoscopy was highlighted as a vital diagnostic tool for pediatric alopecia areata, showing significant hair regrowth in a 4-year-old girl with toxoplasma-related alopecia after six weeks of therapy, emphasizing its role in tracking therapeutic progress.

In this study, researchers found that the thyroxine receptor agonist TDM10842 accelerated the onset of anagen, a hair growth phase, in C3H mice, potentially through activation of the Wnt/beta-catenin and Hedgehog pathways, with Pclaf playing a key role in this process.

In this study, researchers developed "Akaro Spectra," an antiparasitic tablet for dogs using cryodestruction of plant materials, which showed 100% efficacy against Otodectes cynotis ticks by the second day and 93.76% efficacy against Ixodes, Dermacentor, and Rhipicephalus ticks.

This case report presents the first known instance of cutaneous lymphoma in a nondomestic bovid, documented in a 13-year-old addax.

This letter discusses congenital triangular alopecia (TTA), a non-scarring hair loss condition often seen in children, without reporting new clinical findings.

This research reports a new autosomal recessive mutation in mice, 'lanceolate hair', causing generalized alopecia and hair shaft abnormalities, which may serve as a model for Netherton's syndrome in humans.

The document concludes that a unique target-like hair regrowth pattern in alopecia areata may be more common than thought and should be properly identified.

This study identified a novel insertion mutation in the hairless gene that may contribute to the development of congenital atrichia with papular lesions in a Pakistani family.

This study identifies a mutation in the hairless gene that may impact thyroid receptor interaction, contributing to alopecia universalis congenita in an Arab Israeli patient.

The authors concluded that some patients clinically diagnosed with telogen effluvium may actually have alopecia areata incognita, suggested by the presence of dystrophic hairs and development of alopecia patches.

This review discusses traction alopecia in individuals with Afro-textured hair and emphasizes the importance of education to prevent this condition, but it reports no new clinical results.

This study found that astrotactin-2 undergoes unique intramembrane proteolysis during maturation, revealing specific transmembrane topologies and substrate sequence requirements for cleavage.

This report describes an unusual case of proliferating trichilemmal cyst with trichoepitheliomatous change in a young woman, differing from its typical presentation in elderly women.

Traction alopecia is hair loss from pulling on hair too much.

This review discusses the causes and diagnosis of traction alopecia, emphasizing education for high-risk populations as there is currently no cure, and presents no new clinical findings.

A teenager's hair with alternating white and dark bands, known as Pili annulati, is a genetic condition that is usually harmless and often considered attractive.

This report documents a rare case of familial eyelash trichomegaly and synophrys in three siblings, with one sister also having loose anagen hair syndrome, an unreported association.

This case report found that intense focused skin tightening ultrasound reduced excessive underarm sweating by nearly 80% in two patients and was associated with temporary side effects like tenderness and redness.

In this study, increased production of CXCL10 was associated with the infiltration of Th1 and Tc1 cells in acute alopecia areata, suggesting a possible new target for treatment.

In this case report, the authors describe a child with treatment-resistant alopecia areata who successfully responded to leflunomide and anthralin, proposing this combination as a potentially cost-effective alternative for managing recalcitrant cases by possibly inhibiting the JAK/STAT pathway.

This article reviews the genetic and phenotypic characteristics of Trichothiodystrophy and discusses the associated DNA repair defects, but does not report new clinical findings.

This case report describes a 3-year-old boy diagnosed with temporal triangular alopecia, emphasizing the importance of clinical and dermoscopic examination for correct diagnosis due to the condition's rarity and risk of misdiagnosis.
