METHODS Cross-sectional observational study conducted at the Recovery of Cardiothoracic Surgery, using information from a database consisting of a total of 900 patients operated on in this...

To better define the contribution of human parainfluenza viruses (HPIVs) to lower respiratory tract infection in adults, we tested acute- and convalescent-phase serum specimens from hospitalized adults participating in a population-based prospective study of lower respiratory tract infection during 1991-1992. We tested all available specimens from the epidemic seasons for each virus and approxi...

Bacterial infection of the lower respiratory tract can impact on the etiology, pathogenesis, and the clinical course of COPD in several ways. Several recent cohort studies suggest that lung growth is impaired by childhood lower respiratory tract infection, making these individuals more vulnerable to developing COPD on exposure to additional injurious agents. Impairment of mucociliary clearance ...

Acute infection of the lower respiratory tract comprises bronchitis, bronchiolitis, and pneumonia. From a clinical point of view it may be diYcult to distinguish these disease entities and one infection may progress into another. The most common pathogens causing these infections are the primary respiratory viruses (respiratory syncytial virus (RSV), influenza virus, adenoviruses, parainfluenza...

Introduction Chlamydia pneumoniae was initially recognized as a cause of acute lower respiratory tract infections such as pneumonia and bronchitis in both adults and children (1-7), hence the species name “pneumoniae.” Moreover, C. pneumoniae was noted in some individuals to cause a persistent respiratory tract infection following an acute infection (8), which is entirely consistent with the kn...

Copyright © 2008 Massachusetts Medical Society. A cute lower respiratory tract infections are a persistent and pervasive public health problem. They cause a greater burden of disease worldwide than human immunodeficiency virus infection, malaria, cancer, or heart attacks.1 In the United States, they cause more disease and death than any other infection, and there has been little change in morta...

background: increased incidence and severity of acute lower respiratory tract infection (alri) are variably associated with malnutrition. objectives: we aimed to examine the prevalence of malnutrition in under-five year old hospitalized children with alri. patients and methods: children aged from 6 to 60 months, mostly from a low socioeconomic population, admitted with alri, were enrolled prosp...
