Daptomycin, which has shown in vitro activity against C. striatum, may be a viable treatment option for patients with C. striatum endocarditis who are either allergic or refractory to traditional antibiotics.
Infection with methicillin-resistant Staphylococcus aureus (MRSA) has become a worldwide problem and is no longer acquired only in a hospital setting. Community-associated MRSA is an emerging pathogen of increasing interest to both obstetricians and neonatologists, reported in all three trimesters of pregnancy and postpartum, and in neonatal intensive care units, leading to severe outcomes, including neonatal death. This case report describes a serious and potentially life-threatening infection (including wound abscess, septicemia, septic thrombophlebitis, and septic pulmonary emboli) that developed in an otherwise healthy postpartum woman who had screened positive for MRSA in nares, vagina, and rectum at the time of her prior admission in labor as part of a research study. We conclude that asymptomatic nasal, vaginal, and rectal colonization with MRSA occurs in pregnancy and may be a risk factor for serious systemic infection after delivery.
Recent reports have implicated community-associated methicillin-resistant Staphylococcus aureus (MRSA) as a cause of outbreaks in the neonatal intensive care unit (NICU). This study was conducted to determine whether community-associated MRSA caused such an outbreak in our NICU and the extent of nasal colonization with MRSA among exposed babies and health care workers. MRSA recovered from infected and colonized babies were genotyped by pulse-field gel electrophoresis (PFGE). Infection control measures were intensified and included nasal screening for MRSA colonization of exposed babies and all new admissions to the NICU within 24 hours of delivery. PFGE type A was recovered from five infected infants and colonized 81% of the exposed infants. The colonization rate during the outbreak was 9.3% and was 1.9% during admission screening. No MRSA infection occurred during 12 months while admission screening was implemented. Hospital-associated MRSA was the dominant strain in this outbreak. Higher colonization rates occurred during the outbreak period.
In December 2012, a multidisciplinary task force was implemented to address the elevated number of central line associated boodstream infections (CLABSIs) at Newark Beth Israel Medical Center from January 2012 to December 2012. Sixty-eight CLABSIs were documented within the adult inpatient population, resulting in a rate of 14.7 CLABSIs/1,000 central line days in the adult inpatient population. This was well above the national average of 1.87 infections per 1,000 central line days. Most of these infections were noted to be within the critical care units where the rate was at 2.86 CLABSIs/1,000 central line days. However, in 2013, the annual rate was decreased to 0.709 CLABSIs/1000 line days(P<0.001)with similar trends observed across the critical care units. Analysis of CLASBI data indicates that the implementation of a multidisciplinary task force dedicated to appropriate central line insertion, maintenance, and the removal of unnecessary central venous catheters can have an impact on reducing rates of CLASBIs throughout the adult inpatient population, including those within critical care units.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
