Differentiating osteoarticular infections caused by Kingella kingae from those due to typical pathogens in young children

Pediatr Infect Dis J. 2011 Oct;30(10):906-9. doi: 10.1097/INF.0b013e31821c3aee.


Osteoarticular infections caused by Kingella kingae are characterized by mild-to-moderate clinical and biologic inflammatory signs that are different from those caused by Gram-positive cocci. A combined score was built to find the best model to predict K. kingae osteoarticular infections by using the following 4 variables: body temperature <38°C, serum C-reactive protein <55 mg/L, white blood cell count <14,000/mm, and band forms <150/mm.
