[Prevalence of psoriasis vulgaris in West Serbia].

Medical examination of 3135 inhabitants of West Serbia (Uzhice and surrounding areas) was carried out, and 43 (or 1.37%) individual with psoriasis vulgaris were registered. Neither significant differences of psoriasis vulgaris prevalence between males (1.41%) and females (1.33%), nor unequal participation in urban (1.41%) versus rural (1.33%) population, were noted. However, in members of families with psoriasis vulgaris (n = 232; 32 cases with psoriasis) a significant increase of psoriasis (13.79%) was found. Patients with previous familiar heredity became ill (mean year 27.7 +/- 15.3) versus to the others without psoriatic signs (mean year 35.4 +/- 13.5). Approximately 28% of children whose one parent was affected (and about one fourth of sons or daughters of affected fathers, or about one half of sons of affected mothers) manifested psoriasis vulgaris after a certain time. Psoriasis affection in daughters of mother patients was not frequent.
