- Diagnosis of Tinea pedis and onychomycosis in patients from Portuguese National Institute of Health Dr. Ricardo Jorge: a four year studyPublication . Viegas, Carla; Sabino, Raquel; Parada, Helena; Brandão, João; Carolino, Elisabete; Rosado, Laura; Verissimo, CristinaABSTRACT - Tinea pedis and onychomycosis are two rather diverse clinical manifestations of superficial fungal infections, and their etiologic agents may be dermatophytes, non-dermatophyte moulds or yeasts. This study was designed to statistically describe the data obtained as results of analysis conducted during a four year period on the frequency of Tinea pedis and onychomycosis and their etiologic agents. A questionnaire was distributed from 2006 to 2010 and answered by 186 patients, who were subjected to skin and/or nail sampling. Frequencies of the isolated fungal species were cross-linked with the data obtained with the questionnaire, seeking associations and predisposing factors. One hundred and sixty three fungal isolates were obtained, 24.2% of which composed by more than one fungal species. Most studies report the two pathologies as caused primarily by dermatophytes, followed by yeasts and lastly by non-dermatophytic moulds. Our study does not challenge this trend. We found a frequency of 15.6% of infections caused by dermatophytes (with a total of 42 isolates) of which T. rubrum was the most frequent species (41.4%). There was no significant association (p >0.05) among visible injury and the independent variables tested, namely age, gender, owning pet, education, swimming pools attendance, sports activity and clinical information. Unlike other studies, the variables considered did not show the expected influence on dermatomycosis of the lower limbs. It is hence necessary to conduct further studies to specifically identify which variables do in fact influence such infections.

- Monitorização da qualidade das areias em zonas balneares: relatórioPublication . Brandão, João; Rosado, Carmen; Silva, Cecília; Alves, Célia; Almeida, Cristina; Carrola, Cristina; Veríssimo, Cristina; Noronha, Graça; Parada, Helena; Barroso, Manuela; Falcão, Leonor; Rodrigues, Raquel; Sabino, Raquel; Rosado, LauraA qualidade ambiental das praias tem vindo a adquirir uma importância crescente entre os critérios de escolha de destino turístico. Apesar de nos últimos anos a legislação ter evoluído no sentido do ordenamento da zona costeira e do tratamento de águas residuais, o único indicador da qualidade relacionado com a saúde publica que pode permitir aos utentes uma escolha orientada, é a qualidade da água balnear. Justifica-se o estudo da qualidade microbiológica da areia, tendo em consideração que a actual directiva 2006/7/EC defende toda uma estrutura de protecção de qualidade da água balnear e zona envolvente bem como a saúde dos seus utilizadores. Também a Organização Mundial de Saúde no guia “Guidelines for safe recreational waters Volume 1 - Coastal and fresh waters” (publicado em 2003) exprime a preocupação com a qualidade das areias da praia por estas poderem constituir um reservatório de agentes de infecção, sobretudo em zonas balneares onde a utilização da areia apresenta maior relevância. Perante esta motivação, a Associação das Bandeiras Azuis para a Europa, o Instituto do Nacional de Saúde Dr. Ricardo Jorge e o Instituto do Ambiente reuniram esforços no sentido de desenvolver mais este projecto para validar a metodologia desenvolvida em estudos anteriores e alargar a sua aplicação ao território insular.
- Tinea capitis - retrospective analysis of cases diagnosed between 2004 and 2013Publication . Parada, Helena; Sabino, Raquel; Brandão, João; Furtado, Cristina; Veríssimo, CristinaTinea capitis is an infection of the hair and scalp caused by dermatophytes of the genera Trichophyton and Microsporum. Transmission may occur by person to person contact, or indirectly by contact with infected animals. The prevalence varies by country and region, being more prevalent in developing countries; children of are usually the most affected group.This study aims to describe the epidemiology of tinea capitis in the region of Lisbon and Tagus Valley, from January 2004 to December 2013.
