Common Dermatoses in Children Referred to a Specialized Pediatric Dermatology Service in Mexico: A Comparative Study between Two Decades

Abstract

Background. Skin diseases among pediatric patients differ from those in adults. Epidemiological studies are scarce, and those performed in Mexican population date back thirty years. It is likely that these diseases might have changed their frequency. Material and Methods. Retrospective study in first-time patients referred to a pediatric dermatology service between January 1994 and December 2003. Demographics and diagnosis were recorded and compared with the results of a previous study performed in the same institution. Results. We included 5250 patients (52.55% female, 47.47% male) with 6029 diagnoses. The most frequent dermatoses found were atopic dermatitis (14.59%), viral warts (6.62%), acne (5.53%), pityriasis alba (3.98%), melanocytic nevi (3.85%), xerosis (3.57%), keratosis pilaris (3.19%), seborrheic dermatitis (2.37%), hemangioma (2.26%), and papular urticaria (2.24%). Most dermatoses increased their frequency when compared to the previous study. Conclusion. The frequency of pediatric dermatoses in our institution has changed in the last two decades. Environmental and sociocultural factors and institutional policies might account for these results.

Clinical study of paediatric dermatoses

“…In various studies reported by Negi et al, nevi range from 1.6 to 2.3%, which is consistent with the present study. In a study conducted by Ruiz -Maldonado R et al 13 , they were reported in about 2.3%, which is in correlation with present study. In present study, among nevi mongolian spot was most common.…”

Epidemiology of pediatric skin diseases in the mid-western anatolian region of Turkey

“…Many western epidemiologic studies on pediatric skin diseases among PD clinic referrals found viral warts as the most common infectious diseases. 3,[8][9][10] In our study warts were especially common in school age children and adolescents. In a Dutch study, 11 carried among children of school age the prevalence of cutaneous warts was found to be 29%, and a similar British study found the prevalence rate as 33%.…”

Epidemiología de dermatosis pediátricas en la región centro-occidental de Anatolia en Turquía

“…Muchos estudios epidemiológicos occidentales sobre dermatosis entre los pacientes derivados a los consultorios de dermatología pediátrica hallaron que las verrugas virales son las enfermedades infecciosas más frecuentes. 3,[8][9][10] En nuestro estudio, este fue especialmente el caso en los niños de edad escolar y los adolescentes.…”

“…[2][3][4][5][6][7][8][9][10] De hecho, varían notablemente los patrones entre los distintos grupos etarios; por lo tanto, en el futuro, el campo de la dermatología pediátrica debería dividirse en dermatología neonatal, dermatología pediátrica y dermatología adolescente.…”
