Human immunodeficiency virus (HIV) testing sites have been recognized recently as potential settings for hepatitis C virus (HCV) screening since both viruses share common routes of transmission. HIV and HCV prevalence, predictors, co-infection rates, and viral subtypes were studied in 592 attendants at an anonymous HIV Counseling and Testing Center in(More)
Leprosy affects skin and peripheral nerves, and acute inflammatory type 1 reactions (reversal reaction) can cause neurologic impairment and disabilities. Single skin lesion paucibacillary leprosy volunteers (N = 135) recruited in three Brazilian endemic regions, treated with single-dose rifampin, ofloxacin, and minocycline (ROM), were monitored for 3 years.(More)
The lack of well established dosimetry protocols for HDR sources is a point of great concern regarding the uniformity of procedures within a particular country and worldwide. The main objective of this paper is to report the results from ten institutions of an intercomparison of calibration procedures for 192Ir HDR sources currently in use in Brazil. The(More)
BACKGROUND Information is limited about HIV-1 subtypes circulating in less populated Brazilian areas where the AIDS epidemic is expanding, such as in the Central West region. OBJECTIVE To describe HIV-1 subtypes in patients from the States of Goias, Mato Grosso do Sul and Mato Grosso in Central West Brazil. STUDY DESIGN Heteroduplex mobility analysis of(More)
Co-infections with human immunodeficiency virus (HIV) and Mycobacterium leprae represent unique opportunities to investigate the interaction of both pathogens. We determined the immunologic, virologic, and histopathologic characteristics of 22 co-infected Brazilian patients (median age = 38 years, 81.8% males, 72.2% with paucibacillary leprosy, and 95.4%(More)
Antiretroviral (ARV) resistance mutations in HIV-1 may reduce the efficacy of prophylactic therapy to mother-to-child transmission and impact future treatment options. ARV resistance mutations and HIV-1 phylogenetic diversity in protease (PR) and reverse transcriptase (RT) genes were assessed among 77 pregnant women (35 naïve, 42 treated with ARV) from(More)
The spread of HIV-1 infection among women of childbearing age has led to increasing numbers of children at risk of vertical transmission. This study aimed to assess child outcomes among HIV-positive (n=19) and AIDS (n=22) mothers from Central West Brazil. CD4(+) T-cell counts (FACScount, BD) and viral loads (HIV-1 RT-PCR, Amplicor HIV-1 Monitor Roche) were(More)
10603 Background: In Brazil, LABC remains a serious health problem, representing approx. 30% of all newly diagnosed breast cancers. Anthracycline-based neoadjuvant therapy is a standard treatment, but around 30% of pts do not respond. There is no standard approach in these refractory pts. In our institution, these pts receive RT, but almost half (46%) of(More)
