A new study of four cases of MRSA infection in patients who had undergone face lift surgery warns that MRSA-positive surgical site infection "is an increasingly problematic issue in all surgical fields." The study's authors also noted that MRSA-positive infections "will be more prevalent and will require well-developed screening, prevention, and treatment strategies" in the future. MRSA is currently the leading causative pathogen in surgical site infections, as well as in skin and soft tissue infections, the study said.
