Prevalences of skin diseases among primary schoolchildren in Damietta, Egypt.

OBJECTIVES

Information on prevalences of pediatric dermatoses in Egypt is scanty. This study aimed to supplement existing data.

METHODS

A cross-sectional study was conducted in Damietta, Egypt between October 2011 and March 2012. It involved 6162 pupils randomly selected from 30 primary schools. The sample was equally divided (3081 pupils/15 schools) between urban and rural areas. Each participant was interviewed for age, gender, residence and complaint. Hygiene status was evaluated and a clinical examination was carried out for skin diseases. Data were coded and analyzed.

RESULTS

Although most children revealed more than one dermatosis, the majority (76.2%) had not complained of disease. The most common disease group included benign neoplasms (87.0%), followed by pigmentary disorders (68.3%), infections (50.9%), adnexal disorders (14.1%), hypersensitivity diseases (14.0%), genodermatoses (0.3%) and papulosquamous diseases (0.2%). The most common subgroup of diseases comprised parasitic infections (47.5%), among which pediculosis prevailed (47.5%), followed by dermatitis (10.0%) in which pityriasis alba dominated (6.0%), followed by hair disorders (9.3%), bacterial infections (5.9%), urticaria (4.4%), sebaceous gland disorders (2.7%), sweat gland disorders (2.3%), viral infections (1.6%) and fungal infections (0.7%). The most commonly found diseases included, in descending order, acquired melanocytic nevus, post-inflammatory hyperpigmentation, pediculosis, leukoderma, café au lait spots, atrophic scar, cicatricial alopecia, hypertrophic scar, pityriasis alba, papular urticaria, xerosis and impetigo.

CONCLUSIONS

The high prevalence of skin diseases, especially of trauma-related disorders and infections, may be mainly attributable to a lack of appropriate health awareness and care, which has created a tendency within the population to adapt without complaining or seeking medical help. Such circumstances, unfortunately, have resulted in a growing community of silent patients.
