[Risk factors for the development of lung cancer in a cohort of adult smokers].

Background: Identifying risk factors for lung cancer in the population could improve the cost-effectiveness of early detection programs using thoracic computed tomography (CT).

Aim: To examine the risk factors of lung cancer in a cohort of adult smokers.

Patients And Methods: An annual clinical and respiratory functional assessment, chest computed tomography for three years and clinical follow up for five years was carried out in 270 patients aged 65 ± 9 years, 55% males, active or former smokers of 10 or more pack-years.

[Importance of respiratory virus in immunocompetent adult patients hospitalized with community-acquired pneumonia].

Background: Community-acquired pneumonia (CAP) is a relevant worldwide cause of morbidity and mortality in adult population, however its etiology is often not identified and therapy is empirical.

Aim: To assess the etiology of CAP in immunocompetent adult hospitalized patients using conventional and molecular diagnostic methods.

Material And Methods: We prospectively studied 240 adult patients who were hospitalized for CAP to identify the microbial etiology.
