[Early detection of lung cancer using computed tomography among patients with chronic obstructive pulmonary disease].

Background: Chest computed tomography (CT) scan may improve lung cancer detection at early stages in high risk populations.

Aim: To assess the diagnostic performance of chest CT in early lung cancer detection in patients with chronic obstructive pulmonary disease (COPD).

Patients And Methods: One hundred sixty one patients aged 50 to 80 years, active or former smokers of 15 or more pack-years and with COPD were enrolled.

[Clinical predictors of bacteremia in immunocompetent adult patients hospitalized for community-acquired pneumonia].

Background: The clinical usefulness of blood cultures in the management of patients hospitalized with community-acquired pneumonia (CAP) is controversial.

Aim: To determine clinical predictors of bacteremia in a cohort of adult patients hospitalized for community-acquired pneumonia.

Material And Methods: A prospective cohort of 605 immunocompetent adult patients aged 16 to 101 years (54% male) hospitalized for CAP was studied.
