Epidemiological study of hepatitis B and C in a municipality with rural characteristics: Cássia dos Coqueiros, State of São Paulo, Brazil.

Introduction: Hepatitis B and C viral infections remain an important cause of global morbidity and mortality. Studies have been conducted in population groups of large cities, leaving gaps in the knowledge regarding the situation in small municipalities. We aimed to measure the prevalence of hepatitis B and C markers and presence of infection-associated factors.

In vitro activity of antimicrobial combinations against multidrug-resistant Pseudomonas aeruginosa.

Introduction: Pseudomonas aeruginosa isolates related to nosocomial infections are often resistant to multiple antibacterial agents. In this study, antimicrobial combinations were evaluated to detect in vitro synergy against clinical isolates of P. aeruginosa.

Bacterial colonization in hemodialysis temporary dual lumen catheters: a prospective study.

Aims: The use of hemodialysis temporary dual-lumen catheters is often complicated by infections, which may be a significant cause of death among patients with end stage renal disease (ESRD). The aim of this study was to assess the incidence of bacteremia and bacterial colonization related to non-tunneled, non-cuffed, dual-lumen temporary catheters in patients with ESRD submitted to hemodialysis.

Methods: This study included 29 patients with ESRD.

Sensitivity of an immunoenzymatic test for detection of anti-L. brasiliensis antibodies compared to other tests used for the diagnosis of American cutaneous leishmaniasis.

The diagnosis of American cutaneous leishmaniasis (ACL) is frequently based on clinical and epidemiological data associated with the results of laboratory tests. Some laboratory methods are currently being applied for the diagnosis of ACL, among them the indirect immunofluorescence reaction (IIFR), the Montenegro skin test (MST), histopathological examination, and the polymerase chain reaction (PCR). The performance of these methods varies in a considerable proportion of patients.

[Hepatitis C: prevalence and risk factors among patients with HIV/AIDS in Belém Pará, in Brazilian Amazon].

The objective of this investigation was to study the prevalence of hepatitis C virus infection and to identify possible risk factors for its transmission, in 406 adult patients with HIV/AIDS who attended at public health services, in Belém city, Pará, Brazil. The anti-HCV was performed by third generation immunoenzymatic technique, and the HCV RNA by polymerase chain reaction. The overall prevalence of hepatitis C virus was 16% (CI: 12.

[Soroepidemiological survey of hepatitis B virus among HIV/AIDS patients in Belém, Pará--Brasil].

The objective of this investigation was to study the prevalence of hepatitis B virus infection in a sample of 406 adult patients with human immunodeficiency virus infection who attended at the public health care in the city of Belém, Pará, Brazil, as well as analyzing possible risk factors for hepatitis B virus infection. The overall prevalence of hepatitis B virus infection was 51% (CI: 46.1 - 55.
