Clinical Presentation and Management of Pseudomonas Osteomyelitis

Abstract

To determine the incidence and clinical characteristics of Pseudomonas aeruginosa osteomyelitis in children, the records of 144 hospitalized patients under 19 years of age were reviewed; 104 fulfilled the study criteria for the diagnosis of acute or chronic osteonxyelitis. Pseudomonas aeruginosa was recovered from 10.6 percent of the children and was the second most common pathogen isolated. In comparison to children with staphylococcal infections, patients with pseudomonal osteomyelitis were significantly older, gave an antecedent history of penetrating trauma, and lacked clinical and laboratory evidence of systemic illness. The data collected in this study suggest that osteomyelitis due to Pseudomonas aeruginosa is a distinct entity with clinical features differing from those of Staphylococcus aureus. Management should be directed at adequate surgical debridement followed by 10 to 21 days of antimicrobial therapy.
