Characteristics of community-acquired pneumonia in patients with chronic obstructive pulmonary disease.

Study Objectives: Community-acquired pneumonia is a frequent event in the course of chronic obstructive pulmonary disease (COPD). The aim of the present study was to provide information on clinical and microbiological characteristics and outcome of community-acquired pneumonia in these patients, in a comparative study with the non-COPD population.

Design: Prospective study of cases.

Etiology and outcome of community-acquired pneumonia in patients with diabetes mellitus.

Study Objectives: It has been suggested that diabetes mellitus is associated with an increased susceptibility to infection, the risk of using more aggressive therapeutic agents, and increased morbidity and mortality; however, current evidence supporting these events in the field of pneumonia is scarce. The aim of the present study was to provide information on clinical and microbiological characteristics and the outcome of community-acquired pneumonia in patients with diabetes mellitus.

Design: Prospective study of cases.

Community-acquired pneumonia as the initial manifestation of serious underlying diseases.

Purpose: Community-acquired pneumonia is common among patients with coexisting illnesses and it can be the initial manifestation of these comorbid diseases. The objectives of our study were to evaluate the frequency of this association and to analyze whether certain characteristics could predict the presence of unknown comorbid conditions.

Subjects And Methods: Over a 5-year period, we prospectively studied 660 consecutive patients with community-acquired pneumonia seen at our institution.

[Pulmonary nocardiosis as a cause of radiographic imaging of multiple pulmonary nodules].

Lung nocardiosis is a rare disease affecting patients with lymphoreticular neoplasm, immunodeficiency or chronic obstructive pulmonary disease; it can also affect patients who have received transplants. We report a case of lung nocardiosis in which radiographic presentation was acute, with a pattern of multiple bilateral pulmonary nodules ("cannonballs"), requiring us to rule out metastatic disease to arrive at a diagnosis. The patient responded slowly to antibiotic treatment until full resolution.
