OBJECTIVES Clinical polymorphism is a main feature of Q fever and, depending upon the geographic location, differences in its clinical picture have been described. The objective of this study was to determine the epidemiology, clinical features and prognosis of acute Q fever in our area. METHODS From 1985 to 1999, consecutive cases of Q fever, presented(More)
 A prospective descriptive study was designed to determine the impact of highly active antiretroviral therapy (HAART) in the evolution of visceral leishmaniasis (VL) in HIV-1 infected patients. Thirty-two patients were treated with meglumine antimoniate or amphotericin B in lipid formulations. Patients who had undergone previous HAART at study entry (n=17)(More)
 A prospective study was conducted to determine the etiology, clinical features, and outcome in a series of 32 consecutively enrolled HIV-infected patients with prolonged fever in whom high resolution (7.5 Mhz) sonography revealed multiple splenic microabscesses. Conventional (3.5 Mhz) sonography showed no splenic abnormalities in any patients. The(More)
BACKGROUND High-level aminoglycoside resistance (HLAR) that precludes bactericidal synergism with penicillins or glycopeptides and nephrotoxicity related to aminoglycoside treatment are major problems in treating Enterococcus faecalis endocarditis. OBJECTIVE To evaluate the efficacy and safety of ampicillin plus ceftriaxone for treating endocarditis due(More)
Brucella endocarditis is an uncommon focal complication of brucellosis. Presented here are 11 cases of Brucella endocarditis, all managed uniformly. The median duration of symptoms prior to diagnosis was 3 months. Five patients (45%) had underlying valvular damage, and in six (55%) endocarditis involved a normal valve. There was a predominance of aortic(More)

Differences in the incidence, etiology, type, and outcome of infections occurring during the first 6 months after transplantation were evaluated in two consecutive cohorts of kidney recipients who received immunosuppressive regimens based on either azathioprine (plus antilymphocyte globulin, cyclosporine A, and prednisone) (ATG-AZA cohort) or(More)
The use of endovascular catheters is a routine practice in secondary and tertiary care level hospitals. The short-term use of peripheral catheters has been found to be associated with the risk of nosocomial bacteraemia, resulting in morbidity and mortality. Staphylococcus aureus is mostly associated with peripheral catheter insertion. This Consensus(More)
