INTRODUCTION: Some viruses of the Herpesviridae family are frequently the etiologic agents of oral lesions associated with HIV. The aim of this study was to identify the presence of herpes simplex virus types 1 and 2 (HSV-1, HSV-2), Varicella Zoster virus (VZV), Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), human herpesvirus type 6, type 7 and type 8 (HHV-6, HHV-7 and HHV-8) in the oral cavity of HIV-infected children/adolescents and verify the association between viral subtypes and clinical factors. METHODS: The cells of oral mucosa were collected from 50 HIV infected children/adolescents, 3-13 years old (mean age 8.66). The majority (66%) of selected were girls, and they were all outpatients at the pediatric AIDS clinic of a public hospital in Rio de Janeiro. Nested-PCR was used to identify the viral types. RESULTS: Absence of immunosuppression was observed in 66% of the children. Highly active antiretroviral therapy (HAART) was used by 72.1% of selected and moderate viral load was observed in 56% of the children/adolescents. Viral types were found in 86% of the children and the subtypes were: HSV-1 (4%), HSV-2 (2%), VZV (4%), EBV (0%), HCMV (24%), HHV6 (18%), HHV-7 (68%), HHV8 (0%). CONCLUSIONS: The use of HAART has helped to reduce oral lesions, especially with herpes virus infections. The health professionals who work with these patients should be aware of such lesions because of their predictive value and the herpes virus can be found circulating in the oral cavity without causing lesions.

A Mina Osamu Utsumi das Indústrias Nucleares do Brasil (INB), localizada no município de Caldas/MG, esteve em operação de 1982 a 1995, quando ocorreu a paralisação definitiva da lavra e tratamento de minério de urânio. Desde então, a INB tem, como principal passivo, para fins de fechamento, a drenagem ácida gerada na cava, nas pilhas de estéril e na praia de rejeitos. A drenagem ácida de mina (DAM) na Mina Osamu Utsumi é relevante, tanto do ponto de vista ambiental, quanto pelos custos envolvidos na neutralização desta. Em dezembro de 2004, a INB assinou um termo de referência para elaboração e apresentação do plano de fechamento solicitado conjuntamente pelo IBAMA e CNEN. Diversos estudos têm sido realizados como subsídio à preparação do plano de fechamento. Esse artigo apresenta a aplicação do método da Análise de Múltiplas Variáveis (AMV) no estudo da melhor alternativa para o fechamento do "Bota-Fora" BF-4 da INB, dado seu potencial de geração de DAM.

The Osamu Utsumi Mine of the Indústrias Nucleares do Brasil (INB), located in Caldas/MG, extracted and processed uranium from 1982 to 1995, after which, operations were suspended, leaving INB with the liability for mine closure, part of which includes problems with acid drainage from the pit, waste dumps and tailings beach. Acid mine drainage (AMD) at the Osamu Utsumi Mine is relevant because of its environmental impact and its neutralization cost. In December, 2004, INB signed an agreement to prepare and present a closure plan according to IBAMA and CNEN requirements. Since that time several studies are in place in order to subsidise the preparation of the closure plan. This paper presents the study of the best alternative for closing the "Bota-Fora" BF-4, due its AMD generation potential, using the Multiple Account Analysis (MAA) methodology.
