In developing countries skin disease prevalences may affect over 60% of the community and are often poorly managed. The impact of ineffective treatment of skin disease on family life in rural Mexico was investigated. In the community of Cayaco, a house to house questionnaire survey was conducted to study the distribution of skin disease and the use and cost of treatments. The diagnosis of skin lesions was validated by physical examination and in a separate random survey in 120 primary school children. Regression analysis was carried out. 380 households with 1528 people (713 males, 815 women) were surveyed, of whom 207 reported skin disease. 131 attended the outpatient clinic (41 males, 90 females). The commonest skin disease among them was pyoderma (27 patients), followed by scabies (26), pityriasis alba (23), acne (8), dermatophytosis (8), viral warts (8), and pediculosis capitis (8). 66 had other skin conditions ranging from urticaria (2) to scrofuloderma (1). 58 patients had more than one condition, a total of 189 dermatoses. Six conditions accounted for 102 of the dermatoses. 15 patients with scabies and 21 with pyoderma had received ineffective treatment over the previous six months at a mean cost of 66 new pesos and 136 new pesos, respectively. Many of the affected children had missed school: eight days for scabies (12 patients) and 15 days for pyoderma (10 patients). 68 of the 120 primary school children in the random survey had at least one treatable skin condition. In half of the households people had symptoms, and 57% of the children had at least one treatable skin disease. The mean total cost of ineffective treatment for the two commonest conditions over six months was a major financial burden on families where the mean daily wage was 15.2 new pesos. Both diseases are readily curable by eliminating scabies. In the area a new system of community dermatology is implemented with close collaboration between specialists and primary health care workers.

Virtually nothing is known about the prevalence of skin conditions in children in the general population. Although we know something about the relative frequency of skin conditions seen by dermatologists, we do not know how such referrals are influenced by factors such as social class, accessibility to medical services or educational and cultural background. In order to estimate the burden and relative frequency of dermatological disease in children in the community, we measured the point prevalence of skin conditions in 1114 Romanian schoolchildren aged 6-12 years, using the British Association of Dermatologists diagnostic index. The overall point prevalence of children with one or more skin diseases was 22.8%, with no significant differences according to age group or sex, except for pityriasis alba which showed a male predominance (P = 0. 007). The most common diseases were infectious dermatoses such as viral warts and insect bites (6.3%), dermatitis/eczema (5.1%), pityriasis alba (5.1%), keratosis pilaris (4.0%) and urticaria (1. 9%). Together, these five groups accounted for more than 84% of the cases. Of the 1114 children, 213 (19.1%) had only one skin disease and 41 (3.7%) had two skin diseases. While acknowledging the limitations in defining which skin conditions can benefit from medical care, this study suggests that skin disorders are common in Romanian schoolchildren, affecting about one-quarter of 6-12 year olds. Such a point prevalence is likely to be conservative because of the tendency of prevalence estimates to exclude many other dermatoses of short duration. The finding that over 80% of the disorders can be grouped into fewer than six categories is important in informing training programmes and delivery of service for primary health care teams. This study provides a baseline for further studies into the morbidity and use of health care services by children with skin disease in the community.

Studies concerning the prevalence of skin diseases and the general dermatologic services in Ethiopia are limited. A total of 7760 patients with 9725 dermatological diseases were seen by a dermatovenereologist from September 1995 to August 1996 at Kazanchis Health center in Addis Ababa. Male to female ratio was 1.01:1.00. Three thousand eighteen (31.0%) of the total 9725 cases had prior evaluation by other health personnel, including doctors (but not dermatologists). Out of these cases, 2720 (90.1%) were misdiagnosed and mismanaged. This high percentage points to the need for further short-term dermatology training for non-dermatologists. Bacterial, fungal and viral infections were dominating, comprising 19.4%, 18.5% and 6.5% of cases respectively. Infestations (i.e., pediculosis and scabies together) represented 10% of cases. Eczemas contributed 18.1% of the total cases. Photoallergic dermatitis (4.5%), Pityriasis alba (4.4%), urticaria (2.2%), prurigo (2%), benign tumors (1.8%), lichen planus (1.6%) and melasma (1.5%) were also quite common.

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.
