Prevalence of skin diseases among pediatric patients in Turkey.

The pediatric population is composed of persons under 16 years of age, and few studies are available on the dermatological diseases of this group. In the present study, data on a total of 6300 pediatric patients admitted between the years 2004-2006 were analyzed. Hospital-based patient registry records were used for data collection. The data were analyzed according to age, sex and time of admittance. A female preponderance (53%) was observed, and adolescents (12-16 years old) constituted the largest group within the patient population (47.6%). A total of 125 dermatoses were recorded. Acne vulgaris was the most prevalent dermatosis (12.4%), followed by atopic dermatitis (11.8%), contact dermatitis (11.3%), warts (9.5%), seborrheic dermatitis (4.3%) and impetigo (4.1%). Atopic dermatitis was the most frequently seen dermatosis in both infants and preschool-age children, whereas contact dermatitis was more prevalent in school-age children, and acne vulgaris was more prevalent in the adolescent group. The frequencies of some diseases showed seasonal variations. Acne vulgaris, atopic dermatitis, contact dermatitis, psoriasis, xerosis and alopecia areata were more common in winter. In contrast, insect bites, vitiligo, dyshidrotic eczema, impetigo and tinea corporis were more common in summer. Studies of the pediatric population, which constitutes the cornerstone of the community, can play an important role in determining the policies of protective medicine and public health. New studies will help us to better understand the frequency of dermatological diseases in the pediatric population according to age, gender and season, and take precautions with regard to these conditions.
