The maximal, no-load, velocity for the contractile element (Vmax) was estimated in 45 patients. The patients included: 17 with normal left ventricular dynamics; eight with volume overload, compensated; 11 with volume overload, decompensated; three with pressure overload; and six with cardiomyopathy. Contractile element velocity (VcE) during isovolumic contraction was estimated in two ways: (1) ...

The rapid influx of smart devices, including tablets and phones, has greatly accelerated the bring-your-own-device (BYOD) and mobile workforce trends, which in turn is creating an ever-mounting management challenge to today's IT environment. The entry of diverse untrusted devices, multiple operating systems (OSs), and consumer-oriented applications into what used to be a controlled IT environme...

BACKGROUND Helicobacter pylori (HP) infection is present in about 50% of the global population, and is associated with chronic gastritis, peptic disease and gastric malignancies. HP prevalence in Crohn's disease (CD) patients was shown to be low compared to the general population, and its influence on disease activity is yet to be determined. Our aims were to determine the prevalence of HP in a...

BACKGROUND AND STUDY AIMS Inadequate bowel preparation negatively influences the reliability of examinations by video capsule endoscopy (VCE). Currently, only subjective scales are available to describe mucosal visibility. We aimed to design a score that was derived directly from the VCE images. PATIENTS AND METHODS A computed assessment of cleansing score was developed based on color intensi...

Background Neuroendocine tumors (NETs) or carcinoids arise at many different sites of the gastrointestinal tract. The small intestine is the most common site for NETs. Diagnosing small bowel carcinoids remains challenging given their non-specific presentations and the overall low incidence of small bowel tumors. Video capsule endoscopy (VCE) has significanly improved our ability to detect small...

The (unconfined) vapour cloud explosion (VCE) is a dramatic phenomenon that generates severe pressure wave with high potential to damage assets and produce injuries in the far field. This definition applies also hydrogen. Nevertheless, no clear tools methodology have been so developed tested for this highly reactive gas, even advanced numerical simulations lack validation suffer from large unce...

The aim of this study was to compare magnetic resonance enterography (MRE) findings with those of video capsule endoscopy (VCE) or conventional gastrointestinal radiography (CGR) in pediatric patients with small bowel Crohn's disease. A total of 55 cases of small bowel Crohn's disease that were diagnosed through clinical, laboratory, surgical and histopathological findings were reviewed. Prior ...

GOALS AND BACKGROUND Discriminating between patients with nonresponsive but otherwise uncomplicated celiac disease (CD) and patients with refractory celiac disease (RCD) and/or lymphoma is difficult, especially as many abnormalities encountered in complicated CD are not within reach of conventional gastroduodenoscopy. We aimed to describe video capsule endoscopy (VCE) findings in patients with ...

High speed oscilloscopic recordings (4000 mm/sec) of left ventricular pressure (micromanometer) and its first derivative were used to calculate contractile element velocity (Vce) during the isovolumic period of auxotonic beats in anesthetized dogs. At 0.5-2.0 msec intervals of isovolumic systole, Vce was derived as (dP/dt)/kP, where k = 24 cm(-1). Plots of Vce and P yielded inverse curves from ...

Videocapsule endoscopic (VCE) exploration represents a major breakthrough in non-invasive imagistic, especially of the small bowel. Our study group consisted of 29 initial subjects admitted in the 1st Internal Medicine and Gastroenterology Clinic at the Emergency County Hospital of Craiova between June 2008 and March 2009. We have excluded a number of eight subjects from the VCE-group, as their...
