ABSTRACT
INTRODUCTION:
Childhood alopecia is a relative rare event in general paediatric dermatology practice. Hair loss in children may have multiple causes, and there are different types of alopecia according to age groups. The aim of the study was to describe the clinical and epidemiological profile of alopecia in children from two Chilean paediatric hospitals. PATIENTS ANDMETHOD:
Descriptive analysis of clinical records of patients from the Dermatology Department of Roberto del Rio and Luis Calvo Mackenna Hospitals between January 2007 and June 2010. Patients with clinical diagnosis of alopecia were included.RESULTS:
A total of 345 clinical records were analysed, with 179 males (51.9%). The median age was 72 months. Overall, the most common diagnoses were alopecia areata (AA), (36.8%), tinea capitis (TC), (21%), nevus sebaceous (13.2%), and tellogen effluvium (8.7%). According to age groups, in newborns, the most common causes were aplasia cutis and nevus sebaceous. In toddlers, pre-school and school children, the principal causes were nevus sebaceous, AA and TC. Trichotillomania was also significant in school children. In adolescents, nevus sebaceous, AA and tellogen effluvium were the most frequent diagnoses. AA was statistically associated with autoimmune disease, thyroid disease, nail disorder, psychiatric disease, and Down's syndrome. The most common aetiological agent in TC was M. canis (86.6%). Trichotillomania was also statistically associated to psychiatric disorders.CONCLUSIONS:
In this study, the main causes of alopecia in children were acquired and non-scarring alopecia. In our results, the type of alopecia varies according to age group. Some types of childhood alopecia showed a close correlation to psychiatric disorders.Palavras-chave
