Objective: Skin disorders constitute an important problem in children living in developing countries. The aim of the study was to evaluate the prevalence of skin diseases in children aged 0–16 years. Materials and Methods: In the present study, data on a total of 12,206 children aged 0–16 years, admitted to the outpatient clinic of Dermatology Department, Mersin University School of Medicine, between 2001 and 2010 were analyzed. Results: Male/female ratio was 1.1/1. 44.2% of the patients were adolescents. The most common diseases were acne (12.4%), warts (10.5%), and atopic dermatitis (9.3%). Conclusion: 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.

  Introduction Top

There is growing interest in the social, economic, and psychological impacts of dermatological conditions.[1] Between 6% and 24% of the patients in pediatric clinics present with dermatology-related complaints. The biggest issue with pediatric patients is the paucity of data regarding the neonatal period. The aim of the present study was to evaluate the prevalence of skin diseases in children aged 0–16 years.

  Materials And Methods Top

The study included 12,206 children aged between 0 and 16 years who applied to the dermatology outpatient clinic between 2001 and 2010. The patients were divided into four groups according to age: 0–2 years (infants), 3–5 years (preschool-age), 6–11 years (school-age), and 12–16 years (adolescents). Statistical Package for the Social Sciences, software version 16.0 (SPSS Inc., Chicago, IL, USA) was used to create a database and conduct all statistical analyses.

Sociodemographic characteristics of the patients

A total of 12,206 pediatric outpatients were included in the study. The female/male ratio was 1.1/1 (52.5% and 47.5%, respectively). The patients' age ranged from 2 days to 16 years. Their mean age was 9.71 ± 4.91 years.

When the patients were grouped by age, adolescents comprised the largest age group (44.2%). The patient population included 37 neonatal patients (0–28 days, 0.003%). When the age groups were evaluated in terms of gender, we observed that boys predominated in the infant and preschool-age groups (53% and 52.3%, respectively), while girls predominated in the school-age and adolescent groups (50.7% and 56.7%, respectively) [Table 1].

Patient distribution based on disease percentages

The majority of the patients (n = 11,478, 94.1%) had a single diagnosis, 699 (5.7%) had two diagnoses, and 29 (0.2%) had three diagnoses. Therefore, a total of 12,963 diagnoses were recorded. Statistical analyses related to diseases were based on this number. A total of 205 dermatoses were classified in 28 general disease groups. The most common general disease groups were eczema (25.9%), viral diseases (14.2%), and sebaceous gland diseases (13%). These three groups accounted for 53.1% of all diseases. The most common diagnoses were acne, verrucae, and atopic dermatitis. The first 14 diagnoses with a prevalence over 2% accounted for 62.4% (8081 patients) of the total patient group [Table 2].

Sociodemographic characteristics of patients diagnosed with diseases of ≥2% prevalence

The most common diagnoses by gender were acne among girls (14%) and verrucae in boys (11.3%) [Table 3].

Seborrheic dermatitis (64.5%), acne (59.7%), and psoriasis (56.0%) were more prevalent among the female patients, while molluscum contagiosum (59.7%), pityriasis alba (55.7%), and impetigo (58.6%) were more prevalent in the males (P < 0.05).

Evaluation of disease distribution according to the age group showed that atopic dermatitis was the most common disease in the age groups of 0–2 and 3–5 years (20.9% and 19.6%, respectively). The most common conditions in the age groups of 6–11 and 12–16 years were verrucae (14.7%) and acne (26.1%), respectively.

Of the 37 neonatal patients in our study, 23 were female and 14 were male. The diseases seen in this age group are shown in [Table 4].

  Discussion Top

The first major study of skin disorders in the pediatric age group was conducted in South Africa in 1974 with 10,000 patients.[2] The female/male ratio of the patients in our study was 1.1/1. This gender distribution was similar to that in other studies conducted in this age group, both in our country and abroad.[3],[4],[5] Our study revealed that adolescents comprised the largest age group in our patient population. Similar results were also reported in previous studies.[4],[5],[6] There were 37 neonates among our patient population (0.003%). Newborns were found to comprise a small proportion of all pediatric patients in other studies as well (0.97% and 1.2%).[3],[7] However, another previous report cited a higher proportion of neonatal patients (3.6%).[6]

A total of 205 dermatoses were recorded in our study. Another study conducted in Turkey reported 125 diagnoses for 6300 patients.[4] In a Kuwaiti study, 162 dermatoses were documented in a series of 10,000 patients.[3] As the patient number increases, it is expected to also see a greater number of dermatological diseases, which comprise a wide range of conditions.

The most common general disease groups were eczema, viral diseases, and sebaceous gland diseases. Other similar studies also reported eczema as the most common disease group.[3],[4],[8] In studies conducted among this age group in countries such as India, Nigeria, Brazil, and Ethiopia, infections and parasitic diseases were more common than eczemas.[6],[9],[10],[11] These regional differences may be due to factors such as low socioeconomic levels, crowded living conditions, and poor hygiene. Mersin is one of the developed cities in Turkey and has a high urbanization rate, which may explain the higher prevalence of diseases in the eczema group in our study.

The three most common diseases in our study (acne, verrucae, and atopic dermatitis) were similar to those reported in some other studies.[5],[12] Studies from Spain[13] and Egypt[14] reported nevi and pediculosis capitis as the most common conditions, respectively.

Twenty-three (62%) of the neonatal patients were diagnosed with acute and/or transient conditions (miliaria, seborrheic dermatitis, intertrigo, etc.). The remaining 14 patients (38%) had chronic and genetic diseases (ichthyosis, epidermolysis bullosa, aplasia cutis congenita, and hemangioma). As can be seen, neonates predominantly present with acute and transient dermatoses that can usually be treated successfully by pediatricians. Chronic and genetic diseases are generally rare due to their low incidence in the community.

  Conclusion Top

Although pediatric dermatology is a steadily developing subspecialty, it has yet to become established in Turkey or abroad. In the present study, we determined that pediatric patients frequently present to the dermatology outpatient clinic. In particular, we consider our finding that skin infectious and infestations were less common than eczema to be a promising sign for our country. Future studies in this area will improve our understanding of the prevalence of dermatological diseases in the pediatric population, as well as precautions that can be taken to prevent these conditions.
