This study aimed to evaluate the clinical and epidemiological characteristics and associated factors of hair graying. Methods A total of 1541 volunteers between 15 and 65 years old were included in this population-based, cross-sectional study. A questionnaire on characteristics and associated factors of hair graying was filled in by face-to-face interview method. Results One thousand sixty three participants (69.0%) had hair graying. The mean onset age of hair graying was 32.9 ± 9.8 years. It was 31.7 ± 9.5 years in females, whereas 33.7 ± 10.0 years in males (p = 0.001). The most common involved area ...

Abstract Background Telogen effluvium is the most common form of non-scarring alopecia characterized by diffuse hair loss. Ischemia-modified albumin is a marker of oxidative stress and inflammation. Objective The aim of this study was to compare the levels of ischemia-modified albumin of telogen effluvium patients with healthy controls. Methods Ninety-one patients diagnosed with telogen effluvium and 35 healthy volunteers were included in the study. Serum ischemia-modified albumin level was determined by a fast-colorimetric method, and albumin cobalt binding test. The results were evaluated statistically. Results There was...

This article illustrates the evolutive trichoscopy of dissecting cellulitis, from its early phase, through the abscess phase, to the fibrotic cicatricial phase. Trichoscopy complements clinical-pathological classification, representing a complementary tool useful in early diagnosis and monitoring of the patient during treatment.

Abstract Syphilis is an infectious disease that has afflicted mankind for centuries, but a recent increase in worldwide incidence has been evidenced. The authors describe a patient with typical lesions of secondary syphilis and moth-eaten alopecia, whose dermoscopic examination demonstrated empty hair follicles, vellus hair, follicular hyperkeratosis, peripheral black dots, dilated and tortuous vessels, reddish brown background, and hypopigmentation of the hair shafts. Furthermore, this case presented an erythematous background more evident than previously described cases.

This study aimed to characterize the role of BDNF in age-related microglial activation. Initially, we found that degrees of microglial activation were especially evident in the substantia nigra (SN) across different brain regions of aged mice. The levels of BDNF and TrkB in microglia decreased with age and negatively correlated with their activation statuses in mice during aging. Interestingly, aging-related microglial activation could be reversed by chronic, subcutaneous perfusion of BDNF. Peripheral lipopolysaccharide (LPS) injection-induced microglial activation could be reduced by local supplement of BDNF, while shTrkB...

AbstractIntroductionTo investigate the associations of alopecia areata (AA) with serum vitamin  D and calcium levels.MethodsA systematic review of all relevant articles published up to February 2020 in PubMed, Embase, and Cochrane Library databases was conducted. Primary endpoints were serum 25-hydroxyvitamin  D [25(OH)D] levels and vitamin D deficiency, and the secondary endpoint was serum calcium level. Odds ratio (OR) and standardized mean difference (SMD) with 95% CI across studies were analyzed.ResultsData on 1585 patients with AA and 1114 controls from 16 case –control studies and three cross-sec...
