Pulmonary parenchymal complications remain the main cause of morbidity and mortality in human immunodeficiency virus (HIV) infected patients (McGuinness, 1997). Early diagnosis and treatment of these complications are important to improve survival. HIV impairs the immune system, leading the infected person susceptible to a variety of infections, called opportunistic infections, a leading cause ...

PURPOSE OF REVIEW Chronic obstructive pulmonary disease is a major cause of morbidity and mortality worldwide. There is increasing evidence that implicates viral infections as a major risk factor for exacerbations of chronic obstructive pulmonary disease. Recent studies have attempted to better characterize the epidemiology of viral infections in chronic obstructive pulmonary disease, identify ...

Rhodococcus equi is an unusual cause of infection in humans. Infection in immunocompetent patients is extremely rare-only 19 cases in immunocompetent hosts have been reported. Localized infections represent nearly 50% of reported cases. Pulmonary infections account for only 42% of infections in immunocompetent hosts, compared with 84% of infections in immunocompromised hosts. The mortality rate...

BACKGROUND Although pulmonary infarction is usually associated with pulmonary thromboembolism, it can occur with other disorders such as vasculitis, angioinvasive infections, sickle-cell disease, tumor embolism, and pulmonary torsion. STUDY OBJECTIVE To identify causes and presenting features of pulmonary infarctions diagnosed by surgical biopsy in a consecutive series of patients encountered...
