Objectives 1) Understand the extent of methicillin-resistant Staphylococcus aureus among those undergoing intranasal surgery. 2) Be able to describe potential risk factors for MRSA colonization. The purpose of this study is to outline a prevalance of MRSA colonization among those undergoing inranasal surgery, with an exploration of potential risk factors for colonization. Methods Patients undergoing intranasal surgery (endoscopic sinus surgery, rhinoplasty, septoplasty, etc) at a tertiary care medical center had preoperative nasal swab cultures. The primary endpoint was positive culture of methicillin-resistant Staphylococcus aureus (MRSA). Patient demographic information was also collected to ascertain potential risk factors for colonization of MRSA. Results Early results have demonstrated that the prevalence of MRSA in patients is less than the reported prevalence in hospital inpatient populations. Of the initial 25 patients enrolled in this study, none were shown to be colonized with methicillin-resistant Staphylococcus aureus (0/25), with 1 patient having reported a history of MRSA infection (4%). Conclusions Preliminary data suggests that the prevalence of methicillin-resistant Staphylococcus aureus among patients undergoing intranasal surgery is less than the prevalence of inpatient populations as reported in several previous studies. While preliminary data suggests a potential decreased prevalence of MRSA in this population, a much larger sample of patients is needed to make a more definitive statement. In the coming weeks and months, as more data is gathered and the sample size included in the study grows, it will be interesting to note whether the initial trend, as suggested here, continues.

Staphylococcus Aureus Bloodstream Infection

INTRODUCTION: Methicillin-resistant Staphylococcus aureus (MRSA) is spread out in hospitals across different regions of the world and is regarded as the major agent of nosocomial infections, causing infections such as skin and soft tissue pneumonia and sepsis. The aim of this study was to identify risk factors for methicillin-resistance in Staphylococcus aureus bloodstream infection (BSI) and the predictive factors for death. METHODS: A retrospective cohort of fifty-one patients presenting bacteraemia due to S. aureus between September 2006 and September 2008 was analysed. Staphylococcu aureus samples were obtained from blood cultures performed by clinical hospital microbiology laboratory from the Uberlândia Federal University. Methicillinresistance was determined by growth on oxacillin screen agar and antimicrobial susceptibility by means of the disk diffusion method. RESULTS: We found similar numbers of MRSA (56.8%) and methicillin-susceptible Staphylococcus aureus (MSSA) (43.2%) infections, and the overall hospital mortality ratio was 47%, predominantly in MRSA group (70.8% vs. 29.2%) (p=0.05). Age (p=0.02) was significantly higher in MRSA patients as also was the use of central venous catheter (p=0.02). The use of two or more antimicrobial agents (p=0.03) and the length of hospital stay prior to bacteraemia superior to seven days (p=0.006) were associated with mortality. High odds ratio value was observed in cardiopathy as comorbidity. CONCLUSIONS: Despite several risk factors associated with MRSA and MSSA infection, the use of two or more antimicrobial agents was the unique independent variable associated with mortality.
