OBJECTIVE To evaluate the geographic distribution of human T-lymphotropic virus types 1 and 2 (HTLV-1/2) in the State of Minas Gerais, Brazil, in puerperal women whose newborns were tested for HTLV-1/2 during neonatal screening, and to overlap seropositivity with social and economic status determinants. METHODS During September-November 2007, the(More)
OBJECTIVE Congenital toxoplasmosis is a public health problem in Brazil. This study aimed to determine risk factors associated with congenital toxoplasmosis in Minas Gerais which is the second largest Brazilian State based on number of inhabitants, and its territorial extension is larger than that of France. METHODS Population-based case-control study to(More)
Phenylketonuria (PKU) is one of the few genetic diseases in which mental retardation can be prevented. Hence, diagnosis and treatment must be established early. PKU treatment consists of a phenylalanine-restricted diet supplemented with a phenylalanine-free mixture of amino acids. However, it is difficult to adhere to this diet. In the last decade, a better(More)
Toxoplasma gondii is the main infectious cause of human posterior retinochoroiditis, the most frequent clinical manifestation of congenital toxoplasmosis. This investigation was performed after neonatal screening to identify biomarkers of immunity associated with immunopathological features of the disease by flow cytometry. The study included infected(More)
The hepatitis C virus is characterized by significant genetic heterogeneity. It is currently classified into six main genotypes and several subtypes. Determining the genotype of the virus is important in clinical practice for guiding the treatment for individuals with chronic hepatitis C. The prevalence of different genotypes and subtypes of the hepatitis C(More)
