BACKGROUND Trypanosoma cruzi oral transmission is possible through food contamination by vector's feces. Little is known about the epidemiology and clinical features of microepidemics of orally acquired acute Chagas disease (CD). METHODS A case-control, cohort-nested, epidemiological study was conducted during an outbreak of acute CD that affected a(More)

Several recently developed analgesic techniques effectively control pain after major orthopaedic surgery. Neuraxial analgesia provided by epidural and spinal administration of local anesthetics and opioids provides the highest level of pain control; however, such therapy is highly invasive and labor intensive. Neuraxial analgesia is contraindicated in(More)
A Chilean population was compared to low-income and middle/upper-class populations in Birmingham, Ala., with regard to prevalence of congenital cytomegalovirus infection as well as the importance of this infection in neonatal deaths. In the highly seroimmune Chilean (98%) and low-income Birmingham (82%) groups, congenital infections occurred more often(More)
The adw4 subtype of hepatitis B virus (HBV) belongs to a unique genomic group (genotype F) representing the original HBV strains from the New World. Data regarding the prevalence of this subtype among HBV carriers in South America are, however, scarce, and those concerning HBV genotype F are based on only a few samples from Latin America. In this study,(More)
HIV-2 infection was documented for the first time in Venezuela, in a heterosexual couple. Two identical subtype A viral strains exhibiting multiple resistance mutations to antiretroviral drugs were identified. One of the patients suffered from progressive non-immune thrombocytopenia and extranodal NK/T-cell type lymphoma, an association not previously(More)
