Background: Vitiligo is an acquired skin discoloration with melanocytic destruction. Vitiligo is associated with other autoimmune disorders; hence, an autoimmune etiology is among the most important theories for this disorder. The nails can be involved in numerous cutaneous or systemic non-cutaneous disorders. We have taken into consideration previous studies on nail abnormalities in vitiligo and alopecia areata (AA), which are ethologically closely-related, in addition to the few, notwell designed studies on nail changes in vitiligo, and lack of similar studies in Iran. This case-control study was conducted to evaluate the autoimmune etiology of vitiligo with a larger number of participants.Methods: In this case-control study, we assessed the nail characteristics of 303 participants at Razi Hospital, Tehran, Iran from 2013-2014. These changes were also assessed in terms of diseases properties of the case group and included distribution, duration, and presence of other concomitant cutaneous disorders.Results: There was a statistically significant odd’s ratio (OR) for leukonychia in the case and control groups. The relationship between the prevalence of leukonychia and disease duration was meaningful (P0.05). There was no other significant difference between each type of nail abnormality in the case and control groups. We observed no association between these abnormalities and disease duration. None of the nail abnormalities, including leukonychia, had an association with distributionpattern of the disorder.Conclusion: Leukonychia was the most common abnormality in nails of vitiligo patients that had a relation to disease duration.

Background: Acne vulgaris has a multifactorial pathogenesis; however, the exact role of genetic predisposition is not clear. Some studies have reported an association between familiy historyof acne and moderate to severe acne. In this study, we investigated the relationship between familiy history and prevalence of acne vulgaris in girls 8 to 13 years of age.Methods: This case-control study enrolled 400 students. The participants were divided into two groups, case and control, with 200 students per group. The case group consisted of students with acne vulgaris and the control group included those without acne. The severity of acne was determined based on the Global AcneGrading Score (GAGS). The presence of acne in close relatives (father, mother, sister, brother) was determined through face to face interviews with participants’ mothers and phone contacts with other family members. All collected data were analyzed by SPSS software.Results: The case participants had a mean age of 10.62±1.71 years and those in the control group had a mean age of 10.54±1.70 years, which was not statistically significant. The mothers with acne vulgaris had the highest odds ratio (OR: 2.719, 95% CI: 1.788-4.133) between the case and the control groups. The ratio of encountering the probability with both parents developing acne vulgaris between the two groups was 2.346 (95% CI: 1.571-3.503).Conclusion: This study revealed a significant relationship between positive familial history of acne and prevalence of acne vulgaris.
