Two-Dimensional Planimetry for Alopecia Areata Severity Evaluation Compared With Severity of Alopecia Tool: A Pilot Study

In this study, researchers used high-resolution MRI to distinguish anatomical differences in the scalp and hair follicles between tertiary androgenetic alopecia and severe alopecia areata, identifying subcutaneous tissue layer thickness as a key discriminative factor with high diagnostic value.

This study reviewed 39 studies with 3204 patients to identify characteristic trichoscopic findings in alopecia areata, highlighting yellow and black dots, broken, short vellus, and tapering hairs as key indicators. It found no single diagnostic trichoscopic finding but observed trichoscopy's utility in monitoring treatment response.

In this study, optical coherence tomography detected hair follicles at the dermoepidermal junction not visible on the scalp surface in alopecia areata patients, suggesting OCT may help monitor treatment response.

This study found that topical corticosteroids are the most supported first-line treatment for pediatric alopecia areata, with contact immunotherapy as the next best option.

This study developed the Alopecia Areata Investigator Global Assessment (AA-IGA) to measure scalp-hair loss in alopecia areata patients, incorporating perspectives of both patients and clinicians to define treatment success.

This study found that in patients with patchy alopecia areata, certain trichoscopic features like upright regrowing hairs and pigtail hairs are positive predictive markers for treatment success.

This article presents a computer imaging algorithm that may automate and enhance the Severity of Alopecia Tool scoring for alopecia areata through texture analysis of pediatric images.

This article reviews the epidemiology, clinical evaluation, and pathogenesis of alopecia areata and highlights recent advancements, but it does not report new clinical findings.

This review presents standardized methods for assessing and tracking hair loss in alopecia areata but reports no clinical results, with the authors noting time limitations in clinical practice.

In this study, late-onset alopecia areata in Israeli patients was predominantly observed in females with mild disease, showing a high rate of complete hair regrowth but frequent relapses.

This review discusses the role of stem cells in alopecia pathogenesis, highlighting the differences between scarring and nonscarring types, and reports no new clinical results.
