Abstract
Pneumonia is an inflammation of the parenchyma of the lungs. Most cases of pneumonia are caused by microorgan¬isms or noninfectious causes. Pneumonia is a substantial cause of morbidity and mortality in childhood (particularly among children <5 year of age) throughout the world.
Chest radiograph laboratory finding help in early diagnosis of pneumonia in children without need for culture and the hospitals is not well equiped to do all the investigations.
Our goal is to study factors associated with diagnosis of bacterial pneumonia in children.
A total of 50 case was enrolled in the study. children with suspected pneumonia diagnosed by physician was admitted to hospital to be enrolled in the study. Achest radiograph , CRP , WBC count and % PMN was performed on enrollment.
Cases of pneumonia was classified to 2 suggestive types (bacterial and viral) pneumonia by chest X-ray(following the recommendation of WHO).
Suggestive cases of bacterial and viral pneumonias were differentiated by a combination of radiographic findings and laboratory findings. We Follow recommedations of WHO to classify types of pneumonia into 2 types of infection that chest x-ray of bacterial pneumonia infection appear as lobar dence opacity or bronchopneumonic patches but chest x-ray of Viral pneumonia infection appear as bronchopneumonic patches or interstitial infiltrates.
All cases was subjected to the following :
1. Full history and Complete clinical examination .
2. Investigations:
A - Chest X-ray .
B - Blood sample was withdrawn for :
- C-reactive protien (CRP).
- White blood cell count (WBC count).
-Percentage of polymorphnuclear cells(%PMN)
- lymphocytes %
3. Statistical analysis of the study.
The study revealed the following results:
- Localized dence opacity is highly significant for bacterial pneumonia but diffuse bronchopneumonic patches and diffuse interstitial infilterates are highly significant for viral pneumonia
- Positive CRP is high significant and specific for bacterial pneumonia and negative CRP is high significant and specific for viral pneumonia .
- High WBC count is high significant for bacterial pneumonia than viral pneumonia .
- % PMN increase with Bacterial Pneumonia than viral pneumonia infection.
- Lymphocytes % tends to increases with viral pneumonia other than bacterial pneumonia.
- CRP,WBC count ,%PMN and lymphocytes% were strongly associated with a chest radiograph consistent with bacterial infection and helps in diagnosis of type of pneumonia infection .
