Nongonococcal septic arthritis at a major teaching hospital in Riyadh, Saudi Arabia.

Twenty five (25) consecutive cases of nongonococcal septic arthritis admitted to King Khalid University Hospital were retrospectively reviewed. The patients were mostly adults (64%) and Staphylococcus aureus was the most common bacterial species isolated (69%). Predisposing factors were identified in 52% of patients, including diabetes mellitus in seven patients, pre-existing joint disease in two patients and the infection followed intra-articular steroid injections in two patients.

High level resistance to aminoglycosides in enterococci from Riyadh.

Enterococci with high level of aminoglycosides resistance are being reported from different parts of the world with increasing frequency. Treatment of infections caused by such isolates is associated with a high incidence of failure or relapse. This is attributed to the loss of the synergetic effect of aminoglycosides and cell wall active agents against isolates exhibiting this type of resistance.
