BACKGROUND Our ICU has witnessed a gradual increase in infections due to Acinetobacter baumannii complex that has reached a level of stable endemia since 1995. This situation, aggravated by a high degree of resistance, has led to the present prospective study, designed to establish the incidence of Acinetobacter colonization and to investigate the role of(More)
Among community-acquired infections, pneumonia is still a large health problem which is of great interest mainly due its high mortality and morbidity. From 1991 to 1997, 409 patients who had been diagnosed with community-acquired pneumonia and had been admitted to the internal medicine service of a university hospital were prospectively studied. The(More)
INTRODUCTION The diagnostic of the pneumonia is the problems more important for its adequate treatment and best evolution. OBJECTIVES To study in a prospective way the patron clinic de la NAC compared the documented with the not documented in a microbiological way. PATIENTS Y METHODS: We have studied patients with NAC hospitalized in the HUVA between(More)
We studied 71 patients with pneumococcal bacteraemia (PB) who were hospitalized between 1989 and 1993. The Streptococcus pneumoniae was classified as penicillin-sensitive (PS) or resistant (PR). Age, sex, underlying disease (McCabe classification), and other clinical and laboratory features were recorded on admission, at discharge and one month later. The(More)
Nosocomial infections due to Gram-negative bacteria are very important since they are associated with high morbidity and high hospital costs. A prospective study of 250 inpatients was carried out, 200 of whom had Gram-negative bacterial infections. Patients were divided into groups of 50 according to the localization of the infection (urinary, surgical(More)
The extensive nucleotide sequence heterogeneity among independent genotypes of wild polioviruses permits the systematic design of genotype-specific molecular reagents. We have prepared two sets of polymerase chain reaction (PCR) primer pairs specific for the genotype of wild poliovirus type 3 recently endemic to Mexico and Guatemala. Nucleotide sequences of(More)
Bacterial resistance is currently one of the most important problems of infectious pathology. The relation between in vitro and in vivo bacterial resistance is not always well defined because therapeutic failure is also related to other factors (pharmacokinetics and pharmacodynamics). In addition, there are disagreements between the in vitro and in vivo(More)
Despite the advances in therapy, chronic obstructive pulmonary disease (COPD) requires frequent hospital admissions due to acute exacerbations. We carried out a prospective randomized study of two groups of patients with COPD, one (n = 54) treated with azithromycin (500 mg/day) for three days every 21 days during the winter months, and a control group (n =(More)
