ABSTRACT
O eritema ab igne é lesão de pele reticular pigmentada com telangiectasias, causada pela exposição prolongada ao calor. Relatamos o caso de uma adolescente de 12 anos de idade com eritema ab igne produzido por computador laptop. É discutido como os computadores geram calor e a importância da notificação pelos fabricantes da possibilidade de aparecimento desta dermatose nos usuários de computadores portáteis.
Erythema ab igne is a pigmented reticular skin lesion with telangiectasias caused by prolonged exposure to heat. This report describes the case of a 12-year-old adolescent girl with erythema ab igne induced by a laptop computer. The paper also discusses how computers generate heat and how important it is for the manufacturers of these devices to warn consumers of the potential hazards that could occur if the equipment is misused.

Introducción: El prurigo es una reacción cutánea de hipersensibilidad a la picadura de insectos. El objetivo de este trabajo es determinar la incidencia y características clínicas de los pacientes afectados por prurigo en el servicio de Dermatología Pediátrica del Hospital de Clínicas de Curitiba, Paraná, Brasil. Materiales y métodos: Estudio descriptivo y retrospectivo en el que se evalúan los datos de la primera consulta de pacientes entre 0 y 14 años de edad, con diagnóstico clínico de prurigo, atendidos entre 1978 y 2005. En el mismo se analiza la distribución de esta entidad por sexo, raza, edad de inicio del cuadro, procedencia del paciente y estación del año al momento de la consulta. Resultados: Entre 19.410 primeras consultas, el 9% de ellas tuvo diagnóstico de prurigo. El 50% de los pacientes provenía de Curitiba y 38% del área metropolitana circundante. La mitad eran de sexo masculino y el 80% eran caucásicos. Hubo predominio de consulta en los meses de primavera y verano. La edad media fue de 12 meses, siendo el 63% de los pacientes menores de 2 añoDiscusión: En estos 27 años de experiencia, el diagnóstico de prurigo fue frecuente. La incidencia en la literatura es variable y nuestros hallazgos coinciden con los de algunas series de casos previamente publicadas. La proporción de caucásicos afectados en este estudio es semejante a la observada en la población general de Curitiba, de lo que se desprende que no hubo predominio racial. Los síntomas se iniciaron tempranamente en nuestros pacientes, probablemente por las condiciones climáticas y el ambiente doméstico que predisponen a la proliferación de los insectos. Concluimos que el prurigo es prevalente en nuestro medio y su inicio es precoz.
Introduction: Prurigo or papular urticaria is a cutaneous reaction from hypersensitivity to insect bites. The purpose of this work is to determine the incidence and clinical characteristics of patients with papular urticaria at the Pediatric Dermatology Division of the Hospital de Clínicas outpatient unit, Curitiba, Paraná, Brazil. Materials and methods: This descriptive and retrospective study evaluates data from first consultation of patients between 0 to 14 years of age, with clinically diagnosed papular urticaria, seen between 1978 and 2005. Data of disease distribution considering gender, race, age at beginning of symptoms, place of origin and season in which the consultation occurred, is herein analyzed. Results: There were 19,410 first consultations and 9% were diagnosed as papular urticaria. Fifty percent of patients came from Curitiba and 38% from surrounding cities. Half of the affected children were male and 80% were Caucasians. Most of the consultations were seen during spring and summer. Median age was 12 months and 63% patients were younger than two years. Discussion: In our 27 years of experience, the diagnosis of papular urticaria was frequent. The incidence in literature is variable, but we have found similar data with previously reported serious of cases. The proportion of affected Caucasians in this study correlates with the racial distribution of Curitibas general population, so we can address that there was no racial prevalence. The early beginning of symptoms in our patients may be explained by the fact that weather and environmental conditions predispose to insect proliferation. We can conclude that papular urticaria is a common diagnosis in our environment and its beginning is usually early in life.
