Falup-Pecurariu OG, et al. - Researchers investigated the correlation of three distinct presentations of community-acquired pneumonia (CAP) in children, as detected by chest radiographs, with clinical and laboratory findings. Participants were children < 59 months with CAP presenting to pediatric emergency rooms during two years were enrolled prospectively in eight centers across Europe. They reported that alveolar CAP, non-alveolar CAP, and clinical CAP were distinct entities differing by chest radiographic appearance as well as in clinical and laboratory characteristics. Findings revealed that alveolar CAP had unique characteristics, which suggest a relationship with bacterial etiology.
