Risk factors for vancomycin-resistant enterococcal (VRE) bloodstream infection (BSI) were studied at a tertiary-care hospital by comparing 46 patients with VRE-BSI with 46 randomly selected patients with vancomycin-susceptible enterococcal (VSE) BSI. Among patients with an enterococcal BSI, risk factors for mortality were determined. Independent risk(More)
BACKGROUND Vancomycin-resistant enterococci (VRE) are nosocomial pathogens in many U. S. hospitals. OBJECTIVE To determine whether enhanced infection-control strategies reduce transmission of VRE in an endemic setting. DESIGN Prospective cohort study. SETTING Adult oncology inpatient unit. PATIENTS 259 patients evaluated during use of enhanced(More)
Erythematous rashes that are suggestive of early Lyme disease have been associated with the bite of Amblyomma americanum ticks, particularly in the southern United States. However, Borrelia burgdorferi, the causative agent of Lyme disease, has not been cultured from skin biopsy specimens from these patients, and diagnostic serum antibodies usually have not(More)
BACKGROUND Chlorhexidine bathing has been associated with reductions in healthcare-associated bloodstream infection. To determine the impact and sustainability of the effect of chlorhexidine bathing on central venous catheter-associated bloodstream infection, we performed a prospective, 3-phase, multiple-hospital study. METHODS In the medical intensive(More)
BACKGROUND Disseminated infection with Mycobacterium avium complex is the most common opportunistic infection in patients with advanced stages of the acquired immunodeficiency syndrome (AIDS). We studied the efficacy and safety of prophylactic treatment with clarithromycin, a macrolide antibiotic. METHODS We conducted a randomized, placebo-controlled,(More)
Hospital-acquired pneumonia is the second most common nosocomial infection in the United States. Aspiration appears to be the major route for the entry of microorganisms into the lower respiratory tract. Nosocomial pneumonia may be caused by bacteria, viruses and fungi. Aerobic gram-negative bacilli and Staphylococcus aureus are the most common etiologic(More)
BACKGROUND This study was conducted to investigate decreases in catheter-related bloodstream infections (CRBSIs) through an evidence-based multimodal intervention. METHODS This was a prospective interventional study of neonates with a central venous catheter (CVC) from a neonatal intensive care unit database, involving implementation of a multimodal(More)
OBJECTIVE We describe the first outbreak of multiple drug-resistant Acinetobacter baumannii (MDR-Ab) in a neonatal intensive care unit in the United States. DESIGN/METHODS MDR-Ab was identified in the blood of a 24-week gestation, 7-day-old extremely low birth weight neonate. Multiple samplings of surveillance surface cultures were performed on exposed(More)
GOAL To describe the reoccurrence of ecthyma gangrenosum (EG) in two patients with acquired immunodeficiency syndromes (AIDS). OBJECTIVES 1. To describe the clinical characteristics of EG. 2. To discuss causative organism and risk factor for EG in patients with AIDS. 3. To identify rates of relapse/recurrence of EG in patients with AIDS.
OBJECTIVE To determine whether the ear tips of dedicated stethoscopes (DS) that are used on patients prescribed contact precautions for methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus faecium, or multiple antibiotic-resistant Acinetobacter baumannii become contaminated with these micro-organisms. DESIGN Culture of DS(More)
