Pediatric pleural effusions: etiological evaluation in 492 patients over 29 years

Turk J Pediatr. May-Jun 2009;51(3):214-9.

Abstract

Pediatric pleural effusions present a changing profile over time, both in terms of etiological subgroups and causative microorganisms in parapneumonic effusions. This retrospective study aimed to review pediatric pleural effusions in a large cohort over a 29-year period, with special emphasis on the etiological subgroups and microbiological causes of parapneumonic effusions. The medical records of 492 pediatric patients were reviewed for a comparison of subgroups of pleural effusions and microbiological causes of parapneumonic effusions between three decades. Parapneumonic effusions (381 patients) made up 77.4% of the group. Tuberculous pleurisy decreased, but malignant effusions doubled in number over time. A causative microorganism was identified in 34.6% overall, with Staphylococcus aureus and Streptococcus pneumoniae being the two most common. Relative frequency of S. aureus decreased, whereas pneumococci and Haemophilus influenzae were more frequent in recent years.
