BACKGROUND Propionibacterium acnes has been grown on culture in half of the reported cases of chronic infection associated with shoulder arthroplasty. The presence of this organism can be overlooked because its subtle presentation may not suggest the need for culture or because, in contrast to many orthopaedic infections, multiple tissue samples and weeks(More)
BACKGROUND Revisions of apparently "aseptic" shoulder arthroplasties are not infrequently culture positive for Propionibacterium, organisms that may be introduced at the time of the index surgery when the dermal sebaceous glands are transected. This report seeks to answer the question, Do surgeons performing revision shoulder arthroplasty years after the(More)
Propionibacterium acnes is increasingly recognized as an important agent of prosthetic joint infection (PJI). However, the optimum culture conditions for recovery of this organism from PJI specimens have not been determined. By applying a prolonged 28-day culture incubation to all periprosthetic specimens received for bacterial culture from 198 revision(More)
BACKGROUND Better understanding of medical students' perceptions, attitudes, and knowledge about antimicrobial prescribing practices could facilitate more effective education of these future prescribers. METHODS A 24-item electronic survey on antimicrobial prescribing and education was administered to fourth-year medical students at the University of(More)
BACKGROUND Self-medication with antibiotics is an important factor contributing to the development of bacterial antibiotic resistance. The purpose of this study was to evaluate the prevalence of self-medication with antibiotics for the treatment of menstrual symptoms among university women in Southwest Nigeria. METHODS A cross-sectional survey was(More)
Methicillin-resistant Staphylococcus aureus (MRSA) is an important pathogen that has exploded into clinical prominence in a short period. New medications are available for the treatment of MRSA infections, each with its own pitfalls and caveats. However, the resistance profile of the bacteria is becoming more complex. Recent guidelines from the Infectious(More)
BACKGROUND Voriconazole is approved for treatment of invasive aspergillosis and other invasive fungal infections, but the role for therapeutic drug monitoring (TDM) is not clear. METHODS We performed a retrospective cohort study of patients at the University of Washington Medical Center and Fred Hutchinson Cancer Research Center from 2007-2009. We(More)
BACKGROUND Propionibacterium acnes, which normally resides in the skin, is known to play a role in surgical site infection in orthopaedic surgery. Studies have suggested a persistence of propionibacteria on the skin surface, with rates of positive cultures ranging from 7% to 29% after surgical preparation. However, as Propionibacterium organisms normally(More)
