BACKGROUND & AIMS Patients with inflammatory bowel disease (IBD) are at increased risk of a first venous thromboembolism (VTE), yet their risk of recurrent VTE is unknown. We performed a cohort study to determine the risk for recurrent VTE among patients with IBD compared with subjects without IBD. METHODS We assessed 2811 patients with IBD for a history(More)
BACKGROUND AND STUDY AIMS The small bowel is anatomically difficult to examine; disease conditions are rarely located in it, but can be serious. Neither conventional radiography nor push enteroscopy has sufficient sensitivity and specificity to detect distinct lesions. Wireless capsule endoscopy can theoretically allow imaging of the entire small bowel,(More)
(‹)-Tramadol is a centrally acting analgesic with low anity for opioid receptors. It is a synthetic 4-phenylpiperidine analogue of codeine, which is administered orally or intravenously mainly for the treatment of acute pain of intermediate or severe intensity. The main metabolic reactions are Nand O-desmethylation and conjugation with glucuronic acid and(More)
BACKGROUND AND AIMS Patients with inflammatory bowel disease (IBD) are at increased risk of venous thromboembolism (VTE), but data on frequency, site of thrombosis and risk factors are limited. We sought to determine prevalence, incidence as well as location and clinical features of first VTE among IBD patients. METHODS We evaluated a cohort of 2811 IBD(More)
We present the PhantomStation, a novel interface that communicates tactile feedback to remote parts of the user's body. Thus, touch input on interactive surfaces can be augmented with synchronous tactile sensations. With the objective to reduce the number of tactile actuators on the user's body, we use the psychophysical Phantom Sensation (PhS) [1]. This(More)
Baseline capsule endoscopy in patient 1 showed massive villous atrophy in the mucosa of the duodenum and the proxi− mal jejunum, a pseudopolypoid surface structure, and a whitish reticular pattern that was suggestive of dilated lymphatic vessels (Figure 1, 2). Multiple erosions and villous denudation were also ob− served. The mucosa was affected continu−(More)
Bleeding from duodenal varices is a rare complication of portal hypertension. Most patients with duodenal varices have extrahepatic portal hypertension [1]. Due to the limited number of cases, different treatment modalities for duodenal varices have not been compared in randomized controlled trials and most of our current knowledge is obtained from case(More)
Multi-touch screens and surfaces for manipulating digital content play a crucial role in mobile and ubiquitous computing. Augmenting these interactive surfaces with tactile feedback has been found to increase interaction speed, reduce operating errors and minimize visual and cognitive load. Communicating detailed tactile characteristics of virtual elements,(More)
