[Prognostic factors in adult patients hospitalized for pneumonia caused by Legionella pneumophila].

Introduction: Legionellosis is a multisystem bacterial disease, which causes pneumonia with high mortality in patients with comorbidity and admitted in intensive care units (ICU).

Objective: Determine predictors of mortality or ICU admission.

Methods: Retrospective follow-up of patients diagnosed with Legionella pneumophila pneumonia in Complexo Hospitalario Universitario de A Coruña.

[The importance of genotyping of strains for the evaluation and interpretation of 5 school-based epidemic outbreaks of tuberculosis].

Objective: The aim of this study was to describe 5 microepidemics of tuberculosis occurring in schools, establish the risk factors associated with the outbreaks, assess how well a concentric circles strategy for contact tracing predicts infection, and assess the usefulness of genotyping strains in the analysis of the outbreaks.

Material And Methods: The study assessed 5 epidemic outbreaks of tuberculosis using a standard contact tracing procedure. The outbreaks occurred in 2 day nurseries and 2 high schools between 1998 and 2005.
