Resumo: | Introduction: Allergic contact dermatitis in children, although usually considered infrequent, has been the object of numerous recent publications and an apparent increase in prevalence. This may be due to early exposure and sensitization to contact allergens, increasing the likelihood of skin reactions in a new exposure, or the more widespread use of patch tests, which are crucial to the diagnosis of this pathology.Methods: In order to know the characteristics and causes of allergic contact dermatitis in the pediatric age, we evaluated the medical records of patients with < 18 years who were patch tested between January 2005 and December 2014 at the Contact Allergology Unit of the Department of Dermatology University Hospital of Coimbra. The following parameters were analyzed: sex, age, personal and familiar history of atopy, main location of the dermatitis, reactive allergens within the baseline or complementary test series, suspected and final diagnosis.Results: A total of 106 pediatric patients were tested (3.6% of all patients), 68 females (64.2%) and 38 males (35.8%), four aged between 3-5 years (3.8%), 28 between 6-11 years (26.4%) and 74 between 12-17 years (69.8%), 52,8% with a personal history of atopy, 36.8% with facial and/or neck lesions. At least one positive test was observed in 51 patients (48.1%), mostly in girls especially because of nickel (18.9%). Nevertheless there were no positive tests to nickel in the last two years of the study. After nickel, cobalt, p-phenylenediamine, caine mix and palladium were reactive in five patients. Twelve patients reacted to allergens that are not included in the baseline series, mostly to drugs.Discussion: Contact allergy and allergic contact dermatitis were a relatively common diagnosis before the age of 18. An early etiologic diagnosis is important to prevent chronicity of lesions and a possible future negative personal and professional impact. Knowing the main allergens in this age group is important to establish avoidance measures and prevent further sensitization. |

Introdução: A dermatite de contacto alérgica em idade pediátrica, habitualmente considerada pouco frequente, tem sido recentemente objecto de numerosas publicações associadas a um aparente aumento da sua prevalência. Tal pode ser devido a exposição e sensibilização mais precoce a alergénios de contacto ou à mais ampla utilização de testes epicutâneos, cruciais ao diagnóstico desta patologia.Métodos: Com o objectivo de avaliar as características e causas da dermatite de contacto alérgica em idade pediátrica, foram analisados os processos clínicos dos doentes com < 18 anos que efetuaram testes epicutâneos entre Janeiro de 2005 e Dezembro de 2014 na Unidade de Alergologia de Contacto do Serviço de Dermatologia dos HUC. Avaliaram- -se os seguintes parâmetros: sexo, idade, história pessoal e familiar de atopia, localização principal da dermatose, testes positivos a alergénios da série básica ou outros e respectiva relevância, hipótese de diagnóstico e diagnóstico final.Resultados: Foram estudados 106 doentes em idade pediátrica (3,6% do total), 68 do sexo feminino (64,2%) e 38 do sexo masculino (35,8%), quatro com idades compreendidas entre os 3 e 5 anos (3,8%), 28 entre os 6 e 11 anos (26,4%) e 74 entre os 12 e 17 anos (69,8%), 52,8% com antecedentes de atopia e 36,8% com lesões localizadas na face e/ou pescoço. Dos 106 doentes, 51 tiveram pelo menos um teste positivo (48,1%), mais frequentemente no sexo feminino por alergia ao níquel (18,9%). Seguiram-se o cobalto, a p-fenilenodiamina e a mistura de caínas (4,7%) entre os alergénios de série básica e, fora dela, o paládio positivo em cinco crianças. De notar que não observámos testes positivos ao níquel nos últimos dois anos. Doze doentes reagiram apenas a alergénios não incluídos na série básica, sobretudo medicamentos.Discussão: A alergia de contacto e dermatite de contacto alérgica antes dos 18 anos revelaram-se relativamente comuns. O diagnóstico etiológico precoce é importante para evitar a cronicidade das lesões e prevenir possíveis repercussões futuras a nível pessoal e profissional. O conhecimento dos principais alergénios nesta faixa etária poderá orientar medidas preventivas de futuras sensibilizações.Sociedade Portuguesa de Dermatologia e Venereologia2017-07-20T00:00:00Zjournal articleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://doi.org/10.29021/spdv.75.2.769oai:ojs.revista.spdv.com.pt:article/769Journal of the Portuguese Society of Dermatology and Venereology; Vol 75 No 2 (2017): Abril - Junho; 143-152Revista da Sociedade Portuguesa de Dermatologia e Venereologia; v. 75 n. 2 (2017): Abril - Junho; 143-1522182-24092182-2395reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://revista.spdv.com.pt/index.php/spdv/article/view/769https://doi.org/10.29021/spdv.75.2.769https://revista.spdv.com.pt/index.php/spdv/article/view/769/493Cordeiro, Ana CatarinaRamos, LeonorGonçalo, Margaridainfo:eu-repo/semantics/openAccess2022-10-06T12:35:03ZPortal AgregadorONG |
