OBJECTIVE Because Lyme and septic arthritis may present similarly, we sought to identify children with knee monoarthritis at low risk for septic arthritis who may not require arthrocentesis. METHODS We performed a retrospective study of children with knee monoarthritis presenting to 1 of 2 pediatric centers, both located in Lyme disease-endemic areas. Septic arthritis was defined by a positiv...

QUESTIONS UNDER STUDY/PRINCIPLES To assess the usefulness of several laboratory and radiological investigations for the limping child with suspected transient synovitis of the hip. METHODS The medical records of children admitted at our children's hospital for nontraumatic hip pain between 1999 and 2007 were retrospectively reviewed. During the study period, all children without a definite di...
