[Microbiology of bronchoalveolar lavage in infants with bacterial community-acquired pneumonia with poor outcome].

Background: Community-acquired pneumonia (CAP) is one of the most common infectious causes of morbidity and mortality in children <5 years of age. The aim of the study was to clarify the bacterial etiologic diagnosis in infants with CAP.

Methods: A prospective, cross-sectional and descriptive study in patients 6 months to 2 years 11 months of age with CAP with poor outcome was conducted.

[Predictors factors for the extubation failure in two or more times among preterm newborn].

Introduction: With the ventilatory mechanical attendance has been prolonged the life of the preterm newborn (PTNB) critically sick and during that lapse many occasions it is necessary reintubation to PTNB in two or more times with the subsequent damage that makes enter to the patient to a vicious circle with more damage during the same reintubated. The objective of this study was to determine the factors that predict the extubation failure among PTNB from 28 to 36 weeks of gestational age in two or more times.

Material And Methods: It was considered extubation failure when in the first 72 hours of being had extubated the patient; there was reintubation necessity, independent of the cause that originated it.

Detection of the glmM gene in Helicobacter pylori isolates with a novel primer by PCR.

A novel reverse primer (GLM MR1) was designed for detection of the glmM gene in Helicobacter pylori by PCR. The percentage of amplification in clinical isolates using GLM MR1 was 100% for detection of the glmM gene and 86.36% for the ureA gene.
