ABSTRACT

En la actualidad los tatuajes de henna negra se utilizan en forma muy frecuente, por lo que el número de reportes sobre reacciones adversas asociadas a su uso se ha incrementado. La Parafenilendiamina o PPD es el químico que más se adiciona a la henna para intensificar y prolongar la duración del color del tatuaje. Posee un gran poder sensibilizante y se le atribuyen la mayoría de las reacciones, desde dermatitis leve hasta reacciones generalizadas tipo eritema multiforme-like. Se presenta el caso de un paciente de 7 años con lesiones cutáneas frente a segunda exposición a tatuaje de henna. Con diagnóstico de dermatitis de contacto se maneja con corticoidestópicos con excelente respuesta clínica. Como prevención primaria planteamos la necesidad de programas que permitan educar a la comunidad en relación a los riesgos asociados a la exposición a PPD, recomendando el NO uso de tatuajes de henna negra.


Today, black henna tattoos are very commonly used, so the number of reports on adverse reactions associated with its use has increased. The paraphenylenediamine or PPD is the chemical that is most commonly added to henna to intensify and prolong the duration of the color tattoo. PPD act as sensitizer of most of the reactions, from mild dermatitis to generalized reactions erythema multiforme-like. We show a case of a 7 year old patient with skin lesions that appears during the second exposure to henna tattoos. We made the diagnosis of a contact dermatitis and we manage it with topical corticosteroids with excellent clinical response. As primary prevention we suggest the need of educational programs for the community regarding the risks associated with the exposure of PPD, and avoiding the use of black henna tattoos.

ABSTRACT

FUNDAMENTOS: Uma das causas mais frequentes de dermatite de contato alérgica, de origem ocupacional, são os aditivos da borracha, presentes nos Equipamentos de Proteção Individual. Os aditivos das luvas natural e sintética mais alergênicos são tiurams, mercaptos e carbamatos. OBJETIVO: levantar o nível de conhecimento em relação aos aditivos químicos utilizados na fabricação das luvas de borracha sintética. MÉTODOS: Foi aplicado um questionário aberto a profissionais que trabalham com fabricação, pesquisa, prescrição e comercialização das luvas. Foi adotado o método de pesquisa qualitativa. RESULTADOS: Foram entrevistadas 30 pessoas: 4 pesquisadores na área de Medicina do Trabalho, 5 médicos do Trabalho, 2 técnicos de segurança do Trabalho, 1 médico do sindicato de trabalhadores da borracha, 1 engenheiro de Segurança do Trabalho, 1 engenheira de Produção do setor de fabricação de luvas de borracha, 4 empresários importadores de luvas, 1 empresário fabricante de luvas, 3 empresários que comercializavam Equipamentos de Proteção Individual, 3 vendedores de lojas de Equipamentos de Proteção Individual, 2 empresários de lojas que comercializavam produtos para alérgicos e 3 dermatologistas. CONCLUSÃO: O conhecimento da composição química das luvas é pequeno. A rotulagem das luvas, com a descrição da composição química, facilitaria a escolha do melhor tipo de luva para cada pessoa. Esta ação, de baixo custo para as empresas, seria um ganho, do ponto de vista da saúde pública, e teria grande repercussão nos usuários de luvas de borracha.


BACKGROUNDS: One of the most frequent causes of allergic contact dermatitis of occupational origin are rubber additives, which are present in Personal Protective Equipment (PPE). The most allergenic additives of natural and synthetic gloves are thiurams, carbamates and mercapto group. OBJECTIVE: To investigate the state of knowledge about the chemical additives used in the manufacture of synthetic rubber gloves. METHODS: This was a qualitative research study in which professionals working in the manufacture, research, prescription and commercialization of gloves answered an open questionnaire. RESULTS: 30 individuals were interviewed: 4 researchers in occupational medicine, 5 occupational physicians, 2 occupational safety technicians, a rubber workers' union physician, an occupational safety engineer, a pro duction engineer of rubber gloves, 4 importers of gloves, a manufacturer of gloves, 3 businessmen who sell PPE, 3 salesclerks working in stores that sell PPE, 2 businessmen who own stores that sell products for allergic indivi duals, and 3 dermatologists. CONCLUSION: Knowledge of the chemical composition of rubber gloves is scant. The labeling of gloves, with the description of their chemical composition, would facilitate choosing the best type of glove for each person. This low-cost action to businesses would be a gain from the standpoint of public health, with huge repercussions for users of rubber gloves.

ABSTRACT

Jellyfish stings are common worldwide with an estimated 150 million cases annually, and their stings cause a wide range of clinical manifestations from skin inflammation to cardiovascular and respiratory collapse. No studies on jellyfish stings have been carried out in Basra, Iraq. To describe the immediate and delayed skin reactions to White Jellyfish [Rhizostoma sp.] stings and the types of local treatment used by fishermen.] 150 fishermen were enrolled at three Marine stations in Basra, Iraq. Demographic data, types of skin reactions, systemic manifestations and kinds of treatments were collected. Overall, 79% of fishermen in all three Marine stations gave a history of having been stung. The common sites of sings were the hands and arms followed by the legs. Most fishermen claimed that stings led to skin reactions within 5 minutes. The presenting complaints were itching, burning sensation, and erythematic wheals. A few days after the sting, new groups of painless and itchy erythematous monomorphic papular rashes developed at the site of the sting in 62% of cases as a delayed type of skin reaction that resolved spontaneously. The local remedies commonly used by the fishermen were seawater, tap water and ice. A few fishermen considered stings as insignificant and did not think there was a need to seek medical help. We conclude that jellyfish causes many stings among fishermen in the Basra region. Their stings lead to immediate and delayed skin reactions. Self-treatment by topical remedies is common

ABSTRACT

En el barrio El Pato,municipio de Berazategui, provincia de Buenos Aires, se realizó una investigación-acción preventiva contra la “mariposa negra” Hilesia nigricans, luego del aumento de consultas espontâneas por dematitis inespecífica. La incidência, durante el verano del año 2001, se estimo mediante una encuesta semiestructurada. En noviembre de 2002, se roció con Bacillus thuringiensis el arbolado público, evaluándose su efecto insecticida en campo y en laboratorio. El impacto se estimó mediante una encuesta pos-intervención en marzo de 2002. La distribución por edad, signos clínicos, persistência (11 días) y estacionalidad de los casos ( enero-febrero) fue consistente con dermatitis por H . nigricans. La mortalidad de larvas a las 96 horas del rociado fue del 100%. Las tasas de incidencia de dermatitis antes y después de la intervención fueron de 10.3% y 1.8% respectivamente. La acción coordinada de agentes nacionales, provinciales y locales permitió identificar el problema, diseñar investigaciones operacionales, y aplicar una estratégia de control preventivo, transferible por sus mismos efectores a la comunidad.

ABSTRACT

As dermatites alérgicas de contato ocupacionais podem acometer o trabalhador nos seus diversos ramos de atividade, desde que haja condições desfavoráveis e insalubres no ambiente de trabalho. Este estudo apresenta uma análise da ocorrência de dermatites ocupacionais alérgicas entre trabalhadores da indústria. Teve por objetivo realizar levantamento bibliográfico, constatar e analisar as causas e incidência mais comuns e discutir as medidas de prevenção e a promoção de saúde relacionadas à dermatites. Os resultados demonstram que os trabalhadores devem ser orientados e acompanhados por serviços especializados, diminuindo assim a exposição aos agentes e em caso de sensibilização devem ser tratados de maneira adequada, afim de minimizar ao máximo os danos à sua saúde. Medidas preventivas são necessárias nas indústrias, para que se evite a instalação de riscos ao trabalhador e diminua o coeficiente de afastamento ao trabalho
