Metastasis of breast cancer to the thyroid gland.

Metastases to the thyroid gland from nonthyroidal malignant tumors are rare but significant. They are often asymptomatic, indicating advanced-stage primary tumors and poor prognosis. Although infrequently, breast cancer (BC) can metastasize to the thyroid gland.

Are new antibiotics better than beta-lactams for non-critical inpatients with community-acquired pneumonia?

Treatment for community-acquired pneumonia in immunocompetent adults is mainly empirical. Beta-lactam antibiotics have been traditionally considered first-line therapy. New antibiotics could be more effective but the evidence is not clear until now, and its use could entail greater costs, an increase in bacterial resistance and other adverse effects.

[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.
