BACKGROUND No published systematic reviews have assessed the natural history of colonization with methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE). Time to clearance of colonization has important implications for patient care and infection control policy. METHODS We performed parallel searches in OVID Medline(More)
Natalizumab (Tysabri, Biogen Idec and Elan Pharmaceuticals) is a monoclonal antibody approved for use in patients with relapsing multiple sclerosis (MS) as well as moderate to severe Crohn's disease. We report the first case of a patient with a history of MS, on monthly natalizumab, who developed HSV-2 meningitis. We discuss the mechanism of action of(More)
BACKGROUND Nafcillin and cefazolin are considered first-line therapy for most infections with methicillin-susceptible Staphylococcus aureus (MSSA), and recent studies have suggested similar clinical efficacy. Limited data are available on the comparative tolerability of these agents. METHODS In this retrospective cohort analysis of patients treated with(More)
BACKGROUND Methicillin-sensitive Staphylococcus aureus (MSSA) bacteremia is a morbid infection. First-line MSSA therapies (nafcillin, oxacillin, cefazolin) are generally avoided in the 10% of patients reporting penicillin (PCN) allergy, but most of these patients are not truly allergic. We used a decision tree with sensitivity analyses to determine the(More)
BACKGROUND There have been no randomized controlled trials comparing active and passive screening for documenting clearance of colonization with methicillin-resistant Staphylococcus aureus (MRSA). We compared the efficacy of active and passive screening using both culture and commercial polymerase chain reaction (PCR) for documentation of MRSA clearance and(More)
BACKGROUND Methicillin-sensitive Staphylococcus aureus (MSSA) bacteremia is a morbid infection with mortality benefit from receipt of parenteral β-lactam therapy. A substantial portion of MSSA bacteremia patients report penicillin allergy, but infrequently have true allergy. OBJECTIVE To determine the frequency and predictors of optimal and adequate(More)
Background. Ceftaroline fosamil is a cephalosporin approved for treating skin and soft tissue infections (SSTIs), including those caused by methicillin-resistant Staphylococcus aureus (MRSA), and community acquired pneumonia. Given its broad-spectrum activity, its use has expanded. We studied indications for use, adverse drug reactions (ADRs), clinical(More)
Validated skin testing is lacking for many drugs, including ceftaroline. The cross-reactivity between ceftaroline and other β-lactam antibiotics is unknown. We report a case of a pregnant patient with cystic fibrosis and multiple drug allergies who required ceftaroline for methicillin-resistant Staphylococcus aureus pneumonia and underwent an uncomplicated(More)
