In this study, researchers found that transverse sections of alopecia areata lesions showed significantly more terminal hair follicles with perifollicular lymphocytic infiltrate compared to longitudinal sections, and this immune infiltration positively correlated with the positive hair pull test in patients.

This review discusses histologic findings in alopecia and emphasizes the importance of understanding normal follicular anatomy and cycles in transverse sections, without reporting new results.

This study reported that combining vertical and horizontal sectioning in scalp biopsies allows for a more thorough examination of histological changes in various types of alopecia.

This review examines the histopathologic features of four common types of noncicatricial alopecia and reports no new clinical results.

This review discusses the histopathological diagnosis of scarring and non-scarring alopecias, emphasizing the importance of adequate tissue sampling and clinical information; it reports no new empirical results.

Other common signs, not just the well-known immune cells around hair bulbs, are important for diagnosing hair loss from alopecia areata.

This case study suggests that early or significant alopecia in young adults may warrant investigation for underlying congenital conditions like trichorhinophalangeal syndrome.

This study reported that using photomnemonics facilitated accurate histopathologic interpretation of horizontal scalp sections in distinguishing between nonscarring and scarring alopecias by dermatopathologists and residents in a validation test.

This study concluded that horizontal sections of scalp biopsy specimens provide more diagnostic information for male pattern androgenetic alopecia than vertical sections and can predict hair regrowth potential following topical minoxidil therapy.

This study introduces the "HoVert" technique, which generates both vertical and horizontal sections from a single biopsy to effectively differentiate lichen planopilaris from discoid lupus erythematosus in alopecia cases.

This study reports that horizontal sections of scalp biopsies improve the diagnosis of alopecia areata, especially when characteristic inflammatory infiltrates are missing.

This study developed a prototype device that suggests potential for diagnosing changes in hair quantity, diameter, and density, though formal clinical studies are needed to confirm these findings.

This study suggests that a prototype device may accurately measure hair quantity, diameter, and density in balding patients, potentially aiding in diagnostic assessments, though formal clinical studies are needed to confirm its effectiveness.

This study found that horizontal sections of scalp biopsies in patients with Central Centrifugal Cicatricial Alopecia often reveal follicular miniaturization, inflammation, and scarring, which can guide personalized treatment.

This study found that serial vertical sectioning of scalp biopsies significantly increases the histological diagnostic yield for alopecias.

In this study, pigmentary changes were the most common skin changes observed in pregnant women, affecting over 90% of the participants.

This article presents a collection of 70 multiple choice questions designed to assist haematology and core medical trainees with diagnostic and management skills, but it provides no new clinical findings.

This study describes the prescribing habits of Spanish dermatologists, highlighting that topical minoxidil and oral finasteride are the most common treatments for male AGA and postmenopausal female AGA.

This study found that scalp involvement in dermatomyositis consistently shows a nonscarring pattern with chronic telogen effluvium, featuring telangiectasia and mucin deposition as universal histologic markers.

This study observed that triple horizontal scalp biopsies provided a more accurate diagnosis of female pattern hair loss in women than a single horizontal biopsy, especially for those with advanced hair loss.

The meeting discussed medical findings, including benefits of certain treatments for cancer and heart conditions, and highlighted issues like poor adherence to preventive measures and skill gaps among interns.

This study observed that 2.5% of patients with mycosis fungoides or Szary syndrome experienced alopecia, predominantly within skin lesions, with scalp metastases from other cancers also potentially causing hair loss, highlighting the diagnostic value of trichoscopy in differentiating alopecia types.

In this study, nonobese normotensive women with PCOS had higher left ventricular mass index compared to healthy controls, which was linked to inflammation and insulin resistance rather than androgen excess.

This study found that the Elastic Verhoeff–Van Gieson stain may help differentiate between follicular streamers and scars in cicatricial and noncicatricial alopecias by highlighting differences in the elastic fiber network on horizontal scalp biopsy sections.

This study found that despite only topical minoxidil and oral finasteride being approved for androgenetic alopecia in Spain, dermatologists commonly prescribe various off-label treatments for both male and female patients.

This study found that in Colombian women with non-scarring alopecia, decreased serum ferritin levels were associated with telogen effluvium, but no such link was observed with thyroid disorders.

Finasteride 1mg helps reverse hair miniaturization in men and postmenopausal women.

This study found that increased ovarian volume is associated with markers of insulin resistance in women with polycystic ovary syndrome, while follicle number was not linked to metabolic risk.

This study found significant variability in the production and use of platelet-rich plasma and related products in Brazil, highlighting the need for regulatory measures to ensure safety.

This study found no evidence supporting the hypothesis that Aβ afferents sprout into the superficial laminas of the spinal cord after nerve injury in rats.
