    ABSTRACT: Purpose The purpose of this paper was to undertake a systematic review of literature on methicillin-resistant Staphylococcus aureus infections in oral and maxillofacial online data-bases and discuss the Infectious Diseases Society of America (IDSA) guidelines and its applications in maxillofacial clinical practice. Materials and Methods The available literature in oral and maxillofacial online databases was searched. The only inclusion criterion was to review published reports, abstracts and retrospective studies with emphasis on the treatment of clinical cases with methicillin-resistant S. aureus infections. Clinical Practice Guidelines by the Infectious Diseases Society of America for the treatment of methicillin-resistant S. aureus infections in adults and children was reviewed and included in the study. Results Out of 18 articles found with the search terms “Methicillin-resistant S. aureus” and “MRSA” in the online databases 12 articles met the inclusion criteria for this study. The relevant data was extracted and tabulated. Conclusions Conclusions were drawn and discussed based on the reviewed maxillofacial literature and the Guidelines by the IDSA.

    ABSTRACT: We evaluated the published data for the incidence, characteristics and outcomes of patients with community-acquired pneumonia (CAP) due to methicillin-resistant Staphylococcus aureus (MRSA). The estimated incidence of MRSA CAP is 0.51-0.64 cases per 100,000. We identified 74 articles reporting data on 114 patients. Influenza like symptoms was reported in 41% of patients. Pneumonia improved in 59 (54.1%) out of 109 patients; 49 (44.5%) out of 110 patients died. The duration of hospitalisation was 38.1+/-24.9 and 8.3+/-11.7 days, respectively. The duration of intensive care unit (ICU) stay was 18.9+/-13.6 and 6.8+/-9.7 days, respectively. 76 strains carried the Panton-Valentine leukocidin gene. The univariate analysis showed that multi-organ failure (p<0.001), leukopenia (p<0.001), admission to ICU (p<0.001), mechanical ventilation (p<0.001), use of aminoglycosides after culture results (p<0.001), shock (p = 0.001), acute respiratory distress syndrome (p = 0.001), influenza like symptoms (p = 0.008), disseminated intravascular coagulation (p = 0.042) and rash (p = 0.04) were the factors associated with death.

    ABSTRACT: Staphylococcus aureus is an important cause of skin and soft-tissue infections (SSTIs), endovascular infections, pneumonia, septic arthritis, endocarditis, osteomyelitis, foreign-body infections, and sepsis. Methicillin-resistant S. aureus (MRSA) isolates were once confined largely to hospitals, other health care environments, and patients frequenting these facilities. Since the mid-1990s, however, there has been an explosion in the number of MRSA infections reported in populations lacking risk factors for exposure to the health care system. This increase in the incidence of MRSA infection has been associated with the recognition of new MRSA clones known as community-associated MRSA (CA-MRSA). CA-MRSA strains differ from the older, health care-associated MRSA strains; they infect a different group of patients, they cause different clinical syndromes, they differ in antimicrobial susceptibility patterns, they spread rapidly among healthy people in the community, and they frequently cause infections in health care environments as well. This review details what is known about the epidemiology of CA-MRSA strains and the clinical spectrum of infectious syndromes associated with them that ranges from a commensal state to severe, overwhelming infection. It also addresses the therapy of these infections and strategies for their prevention.
