Abstract

The authors analysed 261 cases of mycoplasmal pneumonia in chidren who were admitted to the pediatric department of Seoul Adventist Hospital between July 1986 and June 1991. The result obtained were as follows; 1) Yearly distribution of the cases showed high in 1987 and 1991, but no significant difference was noted in seasonally or monthly distribution. 2) The peak incidence of age was between 2 and 6 years of age, and the sex ratio of boy to girl was 1.1:1. 3) Pulmonary manifestations were asthma in 21 cases (8.0%), atelectasis in 5 cases (1.9%), emphysema in 3 cases (1.2%), pleural effusion in 16 cases (6.1%), otitis media in 4 cases (1.2%) and sinusitis 9 cases (3.4%). 4) Extrapulmonary complication were hepatitis in 53 cases (20.3%), skin rash in 9 cases (2.4%), proteinuria in 6 cases (2.3%), and hematuria in 4 cases (1.5%). 5) On the chest X-ray examination, the most common type of pneumonia was interstitial pneumonia (94 cases, 39.8%), and unilateral involvement was common (85.6%), and the most common involvement was right lower lobe (83 cases, 41.4%). 6) The relationship between the type of pneumonia and cold agglutinin titer, and between the type of pneumonia and Mycoplasma antibody titer were not found (p>0.05). 7) In the 16 cases of pleural effusion, The type of pneumonia was lobar, lobular (9 cases), bronchopneumonia (7 cases), and interstitial type was not present. The site of pneumonia was left (6 cases), right (9 cases), and 1 case showed bilatrality. The extent of pleural effusion was mild (10 cases), moderate (3 cases), and severe (3 cases). The result of pleural fluid exam in severe cases was all exudate. 8) The mean duration of admission was most common from 6 to 10 days. The mean duration of admission by the type of pneumonia was lobar, lobular (10.71¡¾3.40), interstitial (8.78¡¾2.14), and bronchopneumonia (8.83¡¾2.47). 9) Both mycoplasma antibody test and cold agglutinin test were carried out in 185 cases and sensitivity of mycoplasma antibody test was 55.1%.
