PURPOSE To prospectively evaluate reading performance with of 3 types of multifocal intraocular lenses (IOLs) under different lighting conditions based on reading acuity and reading speed tests. SETTING Augenklinik, Bad Hersfeld, Germany. METHODS This randomized study comprised 60 cataract patients (120 eyes) randomly assigned to receive an SA40N IOL(More)
Endotracheal intubation via direct laryngoscopy frequently provokes cardiovascular side-effects. Although using a lightwand intubation device reduces laryngeal stimulation, previous reports indicated a similar stress response compared to classical laryngoscopy. We hypothesized that endotracheal tube (ET) placement itself elicits haemodynamic instability and(More)
BACKGROUND The pathophysiological concept of acute lung injury (ALI) in combination with ventilator-associated lung injury (VALI) is still unclear. We characterized the histopathological features of intravenous injection of oleic acid (OAI) and lung lavage (LAV) combined with VALI. METHODS Pigs were randomized to the control, LAV or OAI group and(More)
OBJECTIVES The aim of this study is to evaluate if theoretically possible edge shifts induced by noise-suppression filters potentially occur on objects found in digital radiographs. Most manufacturers carry out noise-suppression filtering of their images before they are displayed to the user. It is not usually possible for the user to disrupt the function(More)
BACKGROUND The calculation of absolute artery dimensions in quantitative coronary angiography is usually carried out by catheter calibration. It is based on the proportional comparison of the dimension of the imaged artery segment to the dimension of the imaged angiographic catheter of known size. This calibration method presumes an identical radiographic(More)
