title: Lung puncture aspiration in the diagnosis of acute pneumonias.
abstract: The present study was carried out in 100 children of acute pneumonia to establish the diagnosis of etiologic agents. Clinico-radiological assessment and routine investigations including sputum, throat swab and blood culture did not help in identifying the offending micro-organisms. The bacteriological examination of lung puncture aspirate was the most satisfactory tool for the etiological diagnosis. Direct smear examination/culture were positive in 50% aspirates. On cytology, definite epithelioid granulomas indicated tuberculous infection. However, in direct smear/culture negative patients, predominant mononuclear cell infiltration in the aspirated material may indicate non-pyogenic infection. Staphylococcus aureus (22%) was the commonest organism causing pneumonia in the present study.
