[Atypical non-Typhi Salmonella enterica bacteremia, lactose-positive, lysine decarboxylase-negative].

We describe here the first isolation in Argentina of a lactose-fermenting and lysine decarboxylase-negative non-Typhi Salmonella enterica from a blood culture of a patient with systemic lupus erythematosus. The microorganism was identified as S. enterica (score: 2.

[Immune reconstitution syndrome in an HIV-infected patient and Pneumocystis jirovecii pneumonia].

Immune reconstitution syndrome is a set of acute inflammatory phenomena that occur as a result of restored immunity generating a paradoxical worsening of a prior infection or an inflammatory process. This syndrome occurs in human immunodeficiency virus infected patients after starting antiretroviral treatment. The most frequent associated infections are those produced by mycobacteria, herpes, cryptococcosis, hepatitis B, cytomegalovirus, Pneumocystis jirovecii and worsening of progressive multifocal leukoencephalopathy secondary to JC virus.

[Postoperative fever in orthopedic and urologic surgery].

Post-operative fever incidence varies widely. In clean and clean-contaminated surgery the non-infectious fever is more frequent than the infectious fever. We performed a prospective study including 303 patients who underwent orthopedic and urologic elective surgery.
