The aim of this retrospective single-institution observational study was to identify whether the frequency of hospitalizations for pneumonia would change before and after the initiation of noninvasive positive pressure ventilation in children with neurological conditions. Included patients were 1 to 18 years old with an underlying neurological disease and had been prescribed nocturnal noninvasi...

The role of piliation in the development and course of acute pulmonary infection was examined using infant BALB/cByJ mice inoculated by intranasal instillation of isogenic Pil+ and Pil- mutants of Pseudomonas aeruginosa PA1244, PAK, and PAO1. The piliated strains caused more cases of pneumonia, bacteremia, and mortality than the nonpiliated strains (chi-square analysis, alpha = 0.001). The pili...

Cytomegalovirus (CMV) and Aspergillus fumigatus are opportunistic pathogens that cause fatal infections in graft recipients mainly 1–6 months after transplantation, the period of maximal immunosuppression required for the prevention of acute graft rejection. A CMV infection has been known to increase the risk of fungal infection in an immunocompromised host, and concurrent CMV andAspergillus pn...

It has become obvious that several interstitial lung diseases, and even viral lung infections, can progress rapidly, and exhibit similar features in their lung morphology. The final histopathological feature, common in these lung disorders, is diffuse alveolar damage (DAD). The histopathology of DAD is considered to represent end stage phenomenon in acutely behaving interstitial pneumonias, suc...
