Methicillin-resistant Staphylococcus aureus (MRSA) colonization is a predictor of subsequent infection in hospitalized adults. The risk of subsequent MRSA infections in hospitalized children colonized with MRSA is unknown. ⋯ MRSA colonization is a risk factor for subsequent MRSA infection in children. Although MRSA colonized children may have lower risks of subsequent infection than adults, children who acquire MRSA in the hospital have similarly high rates of infection. Preventing transmission of MRSA in hospitalized children should remain a priority.

Multicenter Study Comparative Study
Severity of disease and clinical outcomes in patients with hospital-acquired pneumonia due to methicillin-resistant Staphylococcus aureus strains not influenced by the presence of the Panton-Valentine leukocidin gene.
Patients with community-acquired pneumonia (CAP) infected with methicillin-resistant Staphylococcus aureus (MRSA) strains carrying the Panton-Valentine leukocidin (PVL) gene have severe clinical presentation and poor clinical outcomes. Antibiotics that suppress toxin production have been suggested for the management of these patients. The objective of this study was to compare the severity of disease and clinical outcomes of patients with hospital-acquired pneumonia/ventilator-associated pneumonia (HAP/VAP) infected with MRSA carrying the PVL gene with those patients infected with MRSA strains that do not carry the PVL gene. ⋯ In patients with HAP or VAP due to MRSA, severity of disease and clinical outcomes are not influenced by the presence of the PVL gene. Therapeutic strategies directed to block PVL exotoxin may not impact outcomes in these patients.

Spinal fusion procedures are associated with a significant rate of surgical site infection (SSI) (1%-12%). The goal of this study was to identify modifiable risk factors for spinal fusion SSIs at a large tertiary care center. ⋯ Prolonged duration of closed suction drains is a strong independent risk factor for SSI following instrumented spinal fusion procedures. Therefore, removing drains as early as possible may lower infection rates.

The 2007 Infectious Disease Society of America/American Thoracic Society (IDSA/ATS) guidelines for community-acquired pneumonia (CAP) recommended new criteria to guide admission to the intensive care unit (ICU) for patients with this condition. Although the major criteria (requirement for mechanical ventilation or septic shock requiring vasopressor support) are well established, the value of the minor criteria alone have not been fully validated. ⋯ In a population of patients with CAP without contraindications to ICU care, the IDSA/ATS minor criteria predict subsequent requirement for MV/VS, ICU admission, and 30-day mortality.
