Infection

Linezolid is currently indicated to treat vancomycin-resistant Enterococcus faecium infections, nosocomial pneumonia caused by Staphylococcus aureus or Streptococcus pneumoniae, complicated and uncomplicated skin and skin structure infections, and community-acquired pneumonia. We report a case of linezolid-induced lactic acidosis during treatment of vancomycin-resistant enterococcal bacteremia after mitral valve replacement and permanent pacemaker implantation. We also review the current literature describing other cases of linezolid-associated hyperlactatemia.

Review
Dutch guideline for preventing nosocomial transmission of highly resistant microorganisms (HRMO).
Hospitals are faced with the increasingly rapid emergence and dissemination of antimicrobial-resistant microorganisms. US and European guidelines on the prevention of antimicrobial resistance in hospitals were, until recently, mainly directed at methicillin-resistant Staphylococcus aureus (MRSA). ⋯ The guideline will enable the comparison of HRMO rates between hospitals, and may be used to evaluate the efficacy of programs to control antibiotic use and/or nosocomial transmission of resistant pathogens. The eventual success of nationwide implementation of this guideline remains to be established in the coming years.

Review Case Reports
Isolated bacterial meningitis as the key syndrome of infective endocarditis.
Bacterial meningitis is an unusual first manifestation but a major complication of infective endocarditis. ⋯ An extensive search for endocarditis is recommended in every case of an unusual isolate in bacterial meningitis whether it is isolated from blood or CSF.

Healthcare-associated infections are a major cause of morbidity and mortality at hospitals in the United States. Surveillance of these infections identifies secular trends and provides data upon which prevention interventions can be based in order to improve patient safety. National surveillance of healthcare-associated infections was initiated in the United States in 1970. ⋯ These methods have resulted in a significant reduction in bloodstream infections, urinary tract infections and pneumonia in intensive care unit (ICU) patients and surgical site infections in surgical patients. The NNIS data show that national surveillance of healthcare-associated infections combined with an intervention prevention program can reduce infection rates, reduce morbidity and mortality and improve patient safety. Establishment of such healthcare-associated infection surveillance and prevention systems in countries throughout the world should be a priority.
