چکیده

Chest X-ray findings were studied in 618 pediatric patients with M. pneumoniae respiratory infections. Of these, 472 (76 percent) had pneumonia. Pneumonia was most frequently observed in the lower lung field and least frequently in the upper lung field. The enlargement of hilar lymph nodes was observed in 34 percent of patients with M. pneumoniae pneumonia in contrast to 5 to 9 percent of patients with pneumonia due to other agents, suggesting that it was rather characteristic of M. pneumoniae pneumonia. It was observed in no patients below one year of age, in 41 percent of those aged one to five years, and then decreased with increase in age. Of children with M. pneumoniae respiratory infections, fever, pneumonia, and positive CF test were less frequently observed in infants below one year, showing that they have slighter symptoms; positive IHA test was less frequently observed and isolation of M. pneumoniae was more frequently observed, as compared to other age groups, among whom these findings were similar. It must be kept in mind, however, that fatal cases of M. pneumoniae pneumonia in infants were reported.

Relevance of serology for Mycoplasma pneumoniae infection among children with persistent cough.

BACKGROUND Mycoplasma pneumoniae is an important cause of upper and lower respiratory tract infections. Cough and tracheobronchitis are the commonest features of M. pneumoniae infection but diagnosis based on clinical symptoms that may be due to other respiratory pathogens is impossible. Thus laboratory testing for M. pneumoniae is particularly important. Correct and rapid diagnosis of M. pneum...

Infection with and Carriage of Mycoplasma pneumoniae in Children

"Atypical" pneumonia was described as a distinct and mild form of community-acquired pneumonia (CAP) already before Mycoplasma pneumoniae had been discovered and recognized as its cause. M. pneumoniae is detected in CAP patients most frequently among school-aged children from 5 to 15 years of age, with a decline after adolescence and tapering off in adulthood. Detection rates by polymerase chai...
