A retrospective epidemiological study of skin diseases among pediatric population attending a tertiary dermatology referral center in Northern Greece

View Article: PubMed Central - PubMed

ABSTRACT

Background: The incidence of skin diseases in children is influenced by hereditary, social, and environmental factors. The objective of this study was to determine the incidence of pediatric dermatoses at a University Hospital in Northern Greece.

Patients and methods: We reviewed epidemiologic data of 940 patients, aged 0–18 years, who were referred to the outpatient clinic of a University Hospital between January 2013 and December 2015. Demographic data and the frequency of the various diagnoses in various age groups were studied.

Results: Nine hundred and forty children and adolescents with 1020 diagnoses were included in the study (52.8% females and 47.2% males). The 10 most frequent diagnoses were: dermatitis/eczema (31.5%), viral infections (12.5%), pigmentary disorders (7.4%), melanocytic nevi (5.8%), alopecia areata (5.8%), acne (5.6%), nail disorders (3.3%), vascular malformations and hemangiomas (2.9%), psoriasis (2.6%), and bacterial infections (2.6%). Atopic dermatitis was the most prevalent dermatosis in all age groups accounting for a total of 20.9% of the study population. A remarkably high incidence of various forms of mastocytosis (2.2%) was seen in our data.

Conclusion: Atopic dermatitis is the most frequent pediatric dermatosis in all age groups. Viral infections, pigmentary disorders, and nevi account for a significant proportion of the referrals. The high incidence of mastocytosis in our study may be attributed to overdiagnosis, overestimation due to the relatively small study population, or it may represent the real incidence of mastocytosis in our region. The low incidence of acne in our study may be attributed to the fact that only severe cases are referred to our hospital.

Mentions: The most common type of dermatosis found in our study was dermatitis/eczema, constituting a total of 31.5% of the study population. Atopic dermatitis (AD) was clearly the most common diagnosis of all age groups affecting 20.9% of all patients (63.7% of the dermatitis group). Seborrheic dermatitis (cradle cap) accounted for 9.9% of the dermatitis diagnoses, being the second most frequent dermatitis in newborns and infants. Other subtypes of dermatitis were pityriasis alba (7.8%), contact dermatitis (7.5%), and diaper dermatitis (3.7%), which predominantly affects girls (75%) between 0 and 5 years, nummular eczema (3.7%), dyshidrotic eczema (2.8%), neurodermatitis (lichen simplex chronicus) (0.6%), and photodermatitis (0.3%). The incidence of AD decreased with increasing age, whereas the incidence of contact dermatitis and pityriasis alba showed an opposite trend. Seborrheic dermatitis affected both sexes equally and was most common within the first 4–6 weeks of life, followed by a rapid decline in incidence until puberty. Figure 1 depicts the percentile distribution of the dermatitis/eczema group.
