Abstract
A search of the records at the New York City Department of Health and the charts of patients at Columbia Presbyterian Hospital identified 37 cases of bone infection and nine cases of joint infection due to Salmonella between 1964 and 1978. Factors that apparently contributed to the development of either osteomyelitis or septic arthritis in 23 of the patients included hemoglobinopathy, previous trauma or surgery, connective tissue disorder, and lymphoma. Salmonella typhimurium and Salmonella enteritidis were the most common serotypes involved with bone infections, whereas members of the Ci serogroup were the most common cause of septic joint infections. Isolates of C1 serogroup Salmonella were represented in both bone and joint infections with frequencies (24% and 67%, respectively) disproportionate to the numbers of Salmonella isolated from other sources during this period. Therapy for joint infections was usually successful, with minimal residual damage. Therapy for acute osteomyelitis was unaccountably inadequate, with many patients (47%) developing chronic infections. Use of inappropriate therapy or an insufficient period of therapy were the most important factors contributing to poor outcome.
