“…In our study, the most frequent site was the face; sun exposed areas (face, scalp, upper extremities) were common sites of involvement. These results are similar with that of previous clinical studies (8,9). Therefore, it appears that the development of vitiligo is closely related to sun exposure.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…7 As an important feature of complex diseases, the age of disease onset has routinely been analyzed in association studies. 26 The mean ages of onset of vitiligo that we observed were almost identical to those found in most, [27][28][29] but not all, 30 previous studies. Patients with segmental vitiligo and a negative family history were afflicted at about age 15 years, the same as described by Hann and Lee.…”

“…There was no statistically significant difference between the ages of presentation of males and females (p = 0.476). Levais however noted earlier presentations in females [7]. There were various patient responses to presumed causes of vitiligo.…”
