Respiratory tract infections are a leading cause of death and disability worldwide. Although radiology serves as a primary diagnostic method for assessing respiratory tract infections, visual analysis of chest radiographs and computed tomography (CT) scans is restricted by low specificity for causal infectious organisms and a limited capacity to assess severity and predict patient outcomes. The...

OBJECTIVE To identify the viruses involved in acute respiratory tract infections and to analyze the rates of hospitalization and death in children on palivizumab prophylaxis. METHODS Prospective cohort of 198 infants up to one year old who were born before 29 weeks of gestational age and infants under two years old with hemodynamically unstable cardiopathy or chronic pulmonary disease who rec...

Many neuromuscular disease patient populations suffer from a weak, inadequate cough, which may lead to respiratory tract infections, failure, and increased mortality. Hospitalized neuro...

Viral and bacterial respiratory tract infections are a leading cause of morbidity and mortality worldwide, despite the development of vaccines and potent antibiotics. Frequently, viruses and bacteria can co-infect the same host, resulting in heightened pathology and severity of illness compared to single infections. Bacterial superinfections have been a significant cause of death during every i...

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...

Pulse oximetry was used to measure transcutaneous arterial oxygen saturation in infants aged 2 to 11 months prone and supine in quiet sleep. Groups of healthy infants (n = 34), infants with upper respiratory tract infections (n = 13), and infants with generalised moderately severe lower respiratory tract infections (n = 17) were studied. No clinically important differences were demonstrated in ...
