BACKGROUND Catheter-related bloodstream infection (CRBSI) results in significant attributable morbidity and mortality. In this randomized, double-blind, placebo-controlled trial, we studied the efficacy and safety of a daily ethanol lock for the prevention of CRBSI in patients with a tunnelled central venous catheter (CVC). METHODOLOGY From 2005 through(More)
BACKGROUND Invasive aspergillosis (IA) is a leading cause of mortality in patients with acute leukemia. Management of IA is expensive, which makes prevention desirable. Because hospital resources are limited, prevention costs have to be compared with treatment costs and outcome. METHODS In 269 patients treated for acute myelogenous(More)
BACKGROUND Coronary artery calcification (CAC) has been proposed to be the underlying mechanism of the increased risk of coronary heart disease with reductions in glomerular filtration rate (GFR). Since renal function diminishes with aging we examined the association between GFR and CAC in the Rotterdam Study, a population-based study of elderly(More)
OBJECTIVES The aim of the study was to gain more insight into the relationship between transmitted singletons found at HIV diagnosis by population sequencing and the possible presence of clinically relevant viral minorities containing additional resistance mutations. METHODS We studied the viral quasispecies and therapy response in 10 individuals with(More)
BACKGROUND CONTEXT Patients with sciatica frequently experience disabling back pain. One of the proposed causes for back pain is vertebral end-plate signal changes (VESC) as visualized by magnetic resonance imaging (MRI). PURPOSE To report on VESC findings, changes of VESC findings over time, and the correlation between VESC and disabling back pain in(More)
BACKGROUND CONTEXT The diagnosis of sciatica is primarily based on history and physical examination. Most physical tests used in isolation show poor diagnostic accuracy. Little is known about the diagnostic accuracy of history items. PURPOSE To assess the diagnostic accuracy of history taking for the presence of lumbosacral nerve root compression or disc(More)
BACKGROUND Patients with sciatica frequently complain about associated back pain. It is not known whether there are prognostic relevant differences in Magnetic Resonance Imaging (MRI) findings between sciatica patients with and without disabling back pain. METHODS The study population contained patients with sciatica who underwent a baseline MRI to assess(More)
BACKGROUND CONTEXT Gadolinium-enhanced magnetic resonance imaging (Gd-MRI) is often performed in the evaluation of patients with persistent sciatica after lumbar disc surgery. However, correlation between enhancement and clinical findings is debated, and limited data are available regarding the reliability of enhancement findings. PURPOSE To evaluate the(More)
BACKGROUND Magnetic Resonance Imaging (MRI) is considered the mainstay imaging investigation in patients suspected of lumbar disc herniations. Both imaging and clinical findings determine the final decision of surgery. The objective of this study was to assess MRI observer variation in patients with sciatica who are potential candidates for lumbar disc(More)
Diagnosing catheter-related bloodstream infection (CRBSI) still often involves tip culture. The conventional method is the semiquantitative roll plate method. However, the use of a quantitative sonication technique could have additional value, as it may detect endoluminal microorganisms more easily. Because endoluminal infection tends to occur in long-term(More)
