To determine trends in a number of hemodialysis associated diseases and practices, the Centers for Disease Control and Prevention, in collaboration with the Health Care Financing Administration, completed a mail survey of chronic hemodialysis centers in the United States in 1992. Of 2,321 centers surveyed, 2,170 (93%) representing 170,028 patients and(More)
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 Autistic Disorder is an early-onset developmental disorder with severe lifelong impact on social functioning, communication, and behavior. There is currently no marker or cure. The pathophysiology and etiology are obscure. Evidence for abnormal gamma-aminobutyric acid (GABA) function in Autistic Disorders is limited. A few case-reports and small(More)
Whole blood and peripheral blood mononuclear cell (PBMC) culture models have been used to study cytokine stimulation and release in vitro. In this study, we characterize the kinetics of the interleukins (IL-1 beta), (IL-6), (IL-8), and tumor necrosis factor-alpha (TNF-alpha) following an endotoxin (ET) challenge using our in vitro whole blood model. Whole(More)
From April 1 to October 31, 1985, postoperative surgical-wound infections due to rapidly growing mycobacteria developed in eight patients undergoing cosmetic plastic surgery performed by one surgeon. All infections followed either face-lift or augmentation-mammoplasty procedures performed in the surgeon's office; no infections occurred after surgical(More)
During October and November 1993, four patients contracted Acremonium kiliense endophthalmitis at one ambulatory surgical center. We hypothesized that the source was environmental and conducted a matched case-control study, environmental evaluation, and observational studies. Case and control patients were similar in clinical characteristics. However, case(More)
For identification of risk factors for bloodstream infection (BSI) among neonatal intensive care unit patients, prospective 6-month studies in three neonatal intensive care units were conducted. BSI was diagnosed in 42 of 376 (11.2%) enrolled infants. Pathogens included coagulase-negative staphylococci, Candida sp., Group B streptococci and Gram-negative(More)
In August, 1993, 13 dialysis patients at one dialysis centre in Colombia, South America, were found to be HIV positive, and this prompted an epidemiological investigation. We carried out a cohort study of all dialysis centre patients during January, 1992 to December, 1993 (epidemic period) to determine risk factors for HIV seroconversion. Haemodialysis and(More)
Investigations of nontuberculous mycobacterium (NTM) infections associated with various environmental sources have been hampered by the lack of adequate techniques for selective isolation of these organisms from environmental fluids. This study compared chemical dosing techniques for recovery of NTM from water samples collected from 115 randomly selected(More)
OBJECTIVE To determine risk factors for bloodstream infections (BSIs) in an outbreak among patients receiving home intravenous infusion therapy. DESIGN Case-control and retrospective cohort studies. SETTING Home health agency. PATIENTS Patients receiving home intravenous infusion therapy from Rhode Island Home Therapeutics (RIHT) from January through(More)
