Children with upper-respiratory-tract symptoms and abnormal maxillary radiographs often have bacterial sinusitis. Streptococcus pneumoniae, Haemophilus influenzae, and Branhamella catarrhalis were the most common bacteria found in sinus aspirates.
Area of Science:
Pediatric Infectious Diseases
Otolaryngology
Microbiology
Background:
Maxillary sinusitis is a common condition in children.
Accurate diagnosis relies on correlating clinical, radiographic, and bacteriologic findings.
Distinguishing bacterial sinusitis from viral infections is crucial for appropriate treatment.
Purpose of the Study:
To correlate clinical, radiographic, and bacteriologic findings in pediatric maxillary sinusitis.
To identify common bacterial pathogens in children diagnosed with maxillary sinusitis.
To assess the utility of nasopharyngeal and throat cultures in predicting sinus aspirate findings.
Main Methods:
Prospective study of 30 children with upper-respiratory-tract symptoms and abnormal maxillary radiographs.
Collection of sinus aspirates for bacterial culture and colony counts.
Correlation of clinical signs (cough, nasal discharge, fetid breath, fever, facial pain, headache) with bacteriologic results.
Comparison of sinus aspirate cultures with nasopharyngeal and throat cultures.
Main Results:
Bacterial pathogens were identified in 23 of 30 children (76.7%).
High bacterial colony counts (≥10^4 CFU/mL) were found in 34 of 47 aspirates.
Streptococcus pneumoniae, Haemophilus influenzae, and Branhamella catarrhalis were the most frequently isolated species.
Fever was inconsistently present; facial pain and headache were more common in older children.
Poor correlation was observed between upper respiratory tract cultures and sinus aspirate isolates.
No anaerobic bacteria or significant viral presence were detected.
Conclusions:
Children presenting with upper-respiratory-tract symptoms and abnormal maxillary radiographs frequently have bacterial sinusitis.
Sinus aspirate culture is essential for identifying causative pathogens, as nasopharyngeal/throat cultures are unreliable predictors.
Commonly implicated bacteria include Streptococcus pneumoniae, Haemophilus influenzae, and Branhamella catarrhalis.
