Our study subjects were OHCA cases aged 6 to 17, involving attempted resuscitation by emergency medical service personnel or by bystanders.

An atypical case of atypical pneumonia.

Atypical pneumonia has been thought to account for 7%-20% of community-acquired pneumonia (CAP). The treatment for the pathogens that cause atypical pneumonia is different from that of other bacterial pneumonia. Therefore, identification of the causative pathogen in a primary care situation is crucial for adequate treatment of CAP.
