In patients with AIDS, short-term survival has been related to body weight, body composition, and serum nutritional parameters, but their prognostic impact at earlier stages of the HIV infection is not known. With an individual follow-up period of 1,000 days, we investigated the prognostic relevance of electrical tissue conductivity [resistance R, reactance(More)
BACKGROUND/AIMS The current standard for gastric emptying studies are radioactive isotope methods. [13C]breath tests have been developed as a nonradioactive alternative. The aim of this study was to validate a [13C]acetate breath test as a measure of gastric emptying of the liquid phase both in liquid and semisolid test meals by simultaneous(More)
Intestinal ultrasonography is a meanwhile established and valid diagnostic method in inflammatory bowel disease, diverticulitis, and appendicitis. Little, however, is known about other more rare intestinal diseases. Serving as a tertiary referral center for a broad spectrum of intestinal diseases we therefore report some aspects of ultrasonography in(More)
OBJECTIVE Sonography of the liver, biliary system, and pancreas in adult patients with cystic fibrosis is by far less systematically documented than in pediatric patients with cystic fibrosis. In this prospective study, duplex sonographic findings of the liver, biliary system, and pancreas in adult patients with cystic fibrosis were compared with those of(More)
AIM To evaluate the technical feasibility, safety, and short-term efficacy of botulinum toxin injection for pancreatic sphincter of Oddi dysfunction and to analyse whether the symptomatic response to botulinum toxin might be a predictor of outcome for endoscopic sphincterotomy. METHODS Fifteen consecutive patients (nine female, aged 38 +/- 12 years) with(More)
AIM The value of ultrasonography in the diagnosis, follow-up and for the detection of complications in patients with celiac sprue has not yet been sufficiently evaluated. A pronounced back and forth motility with echo-rich hump reflexes in a fluid-filled small bowel with a reduction of Kerckring's plicae circulares and with a loss of their density and(More)
BACKGROUND Endoscopy with the patient under sedation with propofol requires careful monitoring of patient consciousness and vital signs to achieve the desired hypnotic effect without overdosage. Because level of consciousness is difficult to judge by clinical observation alone, electroencephalogram monitoring has been used to guide general anesthesia. (More)
BACKGROUND Previous studies have suggested an increased risk for Helicobacter pylori infection in physicians who perform UGI endoscopy because of exposure to potentially infectious gastric secretions. Therefore, the H. pylori infection status of the endoscopy staff was compared with the H. pylori prevalence of medical staff without endoscopy experience and(More)
13C-breath tests provide a non-invasive diagnostic method with high patient acceptance. In vivo, human and also bacterial enzyme activities, organ functions and transport processes can be assessed semiquantitatively using breath tests. As the samples can directly be analysed using non-dispersive isotope selective infrared spectrometers or sent to analytical(More)
