A one-year surveillance project was conducted at a large tertiary hospital, which had extensive indoor renovation and extensive demolition/building at several nearby sites. This study collected viable fungi samples in the hospital every six days and analysed 74 duct dust samples for Aspergillus fumigatus mycelial asp f1 protein. Mean total fungi were 257.8(More)
OBJECTIVE We investigated a cluster of cases of bloodstream infection (BSI) due to the mold Phialemonium at a hemodialysis center in Illinois and conducted a cohort study to identify risk factors. DESIGN Environmental assessment and cohort study. SETTING A hemodialysis center in a tertiary care hospital. METHODS A case patient was defined as a person(More)
BACKGROUND Molds are a rare cause of disseminated infection among dialysis patients. OBJECTIVE We evaluated a cluster of intravascular infections with the mold Phialemonium among patients receiving hemodialysis at the same facility in order to identify possible environmental sources and prevent further infection. DESIGN Environmental assessment and(More)
OBJECTIVE The objective of this study was to determine the etiology and risk factors for acute histoplasmosis in two outbreaks in Illinois among laborers at a landfill in 2001 and at a bridge reconstruction site in 2003. DESIGN We performed environmental investigations during both outbreaks and also performed an analytic cohort study among bridge workers.(More)
An evaluation of lead, cadmium, and chromium exposure was conducted during abrasive blasting of a steel bridge to remove paint in preparation for repainting. Airborne lead concentrations were measured at several locations inside the containment structure, as well as near the workers' breathing zones. Airborne cadmium and chromium were also measured in the(More)
The objective of this study was to investigate the concentration level, the mass distribution based on dust particle size, and the associated human exposure of polybrominated diphenyl ethers (PBDEs) in indoor dust. The total concentration of 13 PBDEs Sigma(13)(BDEs) was found to be 500-6,944 ng/g in indoor dusts, 4,000 ng/g in car interior dust, 260-300(More)
The Great Lakes Center of Excellence in Environmental Health (GLCEEH), an innovative capacity-building component of the University of Illinois, performs health hazard evaluations in collaboration with the Illinois Department of Public Health and local health departments. GLCEEH has provided state and local health departments with faculty, industrial-hygiene(More)
CONTEXT Despite considerable evidence that window replacement reduces childhood lead exposure and improves energy conservation and market value, federal policies in childhood lead poisoning, home improvement, and weatherization programs all tend to discourage it. OBJECTIVE AND INTERVENTION To evaluate a state bond-financed pilot program that replaced old(More)
OBJECTIVE We measured lead and other heavy metals in dust during older housing demolition and effectiveness of dust suppression. METHODS We used American Public Housing Association Method 502 and U.S. Environmental Protection Agency Methods SW3050B and SW6020 at 97 single-family housing demolition events with intermittent (or no) use of water to suppress(More)
OBJECTIVE To determine the typical microbial bioburden (overall bacterial and multidrug-resistant organisms [MDROs]) on high-touch healthcare environmental surfaces after routine or terminal cleaning. DESIGN Prospective 2.5-year microbiological survey of large surface areas (>1,000 cm2). SETTING MDRO contact-precaution rooms from 9 acute-care hospitals and(More)
