This review discusses the potential role of vitamins and minerals in managing non-scarring alopecia but reports no clinical results; the authors advocate for further controlled trials to explore these relationships.

This review examines regenerative hair waves and complex hair cycle domains in transgenic mice, highlighting how these dynamic processes contribute to skin regeneration and the physiological regulation of organs, but reports no new experimental results.

This review discusses the potential autoimmune pathogenesis and various contributing factors of alopecia areata, noting that current treatments remain palliative while emerging therapies offer new hope for extensive cases.

This review examines apoptotic and anti-apoptotic mechanisms in skin homeostasis and related diseases but presents no new research findings.

This review discusses the mechanisms and pathways of FGFR signalling and its roles in development, disorders, and therapeutic targeting, but reports no new clinical results.

This essay discusses the establishment, maintenance, and role of skin stem cells in tissue homeostasis, wound repair, and their relation to skin cancer, without reporting new experimental findings.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

This article reviews the characteristics, associations, and diagnostic criteria for alopecia areata and reports no new clinical findings; the authors note the disease's unpredictable course and variable prognosis.

This review discusses the multifactorial etiology of hypospadias, including genetic predispositions and possible environmental factors, and highlights the need for further studies on genetic and environmental contributions to its increasing prevalence, without presenting new findings.

This review discusses the role of immune privilege collapse in the pathogenesis of alopecia areata, emphasizing the potential for therapeutic manipulation of hair bulb immune privilege to offer new treatment options, and reports no new results.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

This study found that the transcription factor p63 is crucial for horizontal basal cell differentiation in the olfactory epithelium, suggesting a p63-dependent mechanism activates reserve stem cells after injury.

This review outlines the classification, histopathologic presentation, and pathogenetic concepts of scarring and nonscarring alopecias, reporting no new clinical results and emphasizing the need for clinicopathologic correlation.

This study found that epidermal Wnt production is crucial for forming the skin's spinous layer through a BMP-FGF signaling cascade, although Wnt from basal cells is not needed for their differentiation.

This review discusses the use of biotin for hair and nail growth, noting clinical improvement in cases with existing pathologies, but concludes there is insufficient evidence supporting its benefits for healthy individuals.

Amenorrhea is relatively rare and initial testing should check FSH, TSH, and prolactin levels.
