- Improving Influenza Surveillance in Portuguese Preschool Children by Parents' ReportPublication . Paixão, P; Piedade, C; Papoila, AL; Caires, I; Pedro, C; Santos, M; Silvestre, MJ; Brum, L; Nunes, B; Guiomar, R; Curran, M; Carvalho, A; Marques, T; Neuparth, NInfluenza surveillance is usually based on nationally organized sentinel networks of physicians and on hospital reports. This study aimed to test a different report system, based on parents' phone contact to the research team and in home collection of samples by a dedicated team. The identification of influenza and other respiratory viruses in children who attended a Hospital Emergency Department was also recorded. Real-time PCR and reverse transcription PCR were performed for influenza A and B, parainfluenza 1-4, adenovirus, human metapneumovirus, respiratory syncytial virus A and B, rhinovirus, enterovirus, group 1 coronaviruses, group 2 coronaviruses, and human bocavirus. One hundred children were included, 64 from the day care centers and 36 from the Hospital. Overall, 79 samples were positive for at least one respiratory virus. Influenza A (H3) was the virus most frequently detected: 25 cases, 20 of these in children under 5 years of age (ten from day care centers and ten who went to the hospital) which was higher than those reported by the National Influenza Surveillance Programme for this age. CONCLUSION: The results obtained in this study suggest that a surveillance system based on parents' reports could complement the implanted system of the National Influenza Surveillance Programme.
- Kerion Caused by Microsporum Audouinii in a ChildPublication . Fernandes, S; Amaro, C; Martins, ML; Inácio, J; Araújo, T; Vieira, R; Silvestre, MJ; Cardoso, JKerion celsi is rarely associated with Microsporum audouinii infection. We report the case of a 3-year-old girl with a kerion celsi caused by M. audouinii and successfully treated with oral terbinafine. Fungi identification was made by macro and microscopical colony morphology analyses and molecular (genotypic) studies.
- Tinea Capitis no Adulto. Um Diagnóstico a Considerar?Publication . Fernandes, S; Coelho Macias, V; Araújo, T; Fernandes, C; Vieira, R; Silvestre, MJ; Cardoso, JA tinea capitis, uma infecção por fungos dermatófitos do couro cabeludo, é uma patologia rara no adulto, mesmo em áreas geográficas onde a doença é prevalente. Nestes casos está muitas vezes, mas não exclusivamente, associada a imunodepressão e habitualmente surge por exposição ao agente infeccioso em contactantes próximos. São fundamentais uma história clínica e um exame objectivo minuciosos que permitam equacionar a tinha do couro cabeludo como hipótese diagnóstica e proceder à colheita de amostras para exame micológico. Esta metodologia pode evitar a realização de exames complementares exaustivos ou a prescrição de tratamentos inadequados. Os autores descrevem três casos de tinea capitis em mulheres adultas – dois casos de infecção por Microsporum audouinii e um caso por Trichophyton soudanense. É apresentado o registo iconográfico dos casos e é efectuada breve revisão da literatura.
