BACKGROUND AND STUDY AIMS Olympus recently developed a new algorithm called Omni mode that discards redundant video capsule endoscopy (VCE) images. The current study aimed to demonstrate the non-inferiority of the Omni mode in terms of true positives (TPs) and the superiority of the Omni mode with regard to reading time against a control (ordinary ES-10 system). PATIENTS AND METHODS This mult...
Coffee enemas are believed to cause dilatation of bile ducts and excretion of bile through the colon wall. Proponents of coffee enemas claim that the cafestol palmitate in coffee enhances the activity of glutathione S-transferase, an enzyme that stimulates bile excretion. During video capsule endoscopy (VCE), excreted bile is one of the causes of poor preparation of the small bowel. This study ...
A finite-element-based toolset has been developed to simulate arbitrary evolution of 3-D, geometrically explicit, interlaminar delaminations in composite structures. A new energy-based growth formulation uses the virtual crack extension (VCE) method to predict point-by-point growth along the delamination front. The VCE method offers an accurate and computationally efficient means to extract bot...
As the size and complexity of high performance computing applications continue to increase, their computing, storage and connectivity requirements become more and more di cult to accommodate on any single computing platform. The Virtual Computing Environment (VCE) combines heterogeneous computing, storage and network resources into a exible system for the execution of large scale applications. ...
Gastrointestinal (GI) bleeding cases in whom source cannot be identified after conventional upper and lower GI endoscopy are defined as potential small bowel bleeding. We aimed to search for lesions in the reach of conventional endoscopy in patients to whom video capsule endoscopy (VCE) had been applied for potential small bowel bleeding. 114 patients who had VCE evaluation for potential small ...
2 This work was supported in part by the New Jersey Information-Technology Opportunities for the Workforce, Education and Research (NJ I-TOWER) Project, funded by the New Jersey Commission on Higher Education (contract #01-801020-02) Abstract. Legitimacy is a key part of the social requirements specification for a trusted virtual community environment (VCE). If an environment is not seen as leg...
BACKGROUND AND STUDY AIMS In videocapsule endoscopy examination (VCE), subtle variations in mucosal hue or pattern such as those seen in ulcerations can be difficult to detect, depending on the experience of the reader. Our aim was to test whether virtual chromoendoscopy (VC) techniques, designed to enhance the contrast between the lesion and the normal mucosa, could improve the characterizatio...
Small-bowel lymphangiomata (SBLs) are benign and relatively uncommon tumors of the lymphatic system [1]. Although SBLs are usually clinically silent, they may rarely present with significant small-bowel bleeding, protein-losing enteropathy, and intussusception [2, 3]. A 54-year-old-man with a past medical history of stable chronic lymphocytic leukemia presented with transfusion-dependent obscur...
[1] We propose a methodology to assess the noise characteristics in time series of position estimates for permanent Global Positioning System (GPS) stations. Least squares variance component estimation (LS-VCE) is adopted to cope with any type of noise in the data. LS-VCE inherently provides the precision of (co)variance estimators. One can also apply statistical hypothesis testing in conjuncti...
OBJECTIVE To evaluate the diagnostic yield of video capsule endoscopy (VCE) in patients with small bowel gastrointestinal bleeding and examine the impact of this diagnostic technology on the clinical management of this complaint. METHODS This was a retrospective study in which all patients who underwent VCE (May 7, 2003 - December 31, 2011) were included. Records were reviewed for the type of...
