Irritable bowel syndrome (IBS) is a common gastrointestinal disorder. In a previous study the total number of endocrine cells in the rectum of IBS patients, as detected by chromogranin A, did not differ from that of healthy controls. While the total endocrine cell content of the rectum appears to be unchanged in IBS patients, changes in particular endocrine(More)
Several abnormalities have been demonstrated in the intestines of patients with irritable bowel syndrome (IBS); however, the endocrine cells in the stomachs of these patients have not been investigated. The aim of the present study was to determine whether there are any abnormalities in the endocrine cells of the stomachs of patients with IBS using(More)
Background and Aim. Chromogranin A (CgA) is a common marker for endocrine cells. The density of duodenal CgA cells is reduced in patients with irritable bowel syndrome (IBS). Methods. The present study was undertaken to evaluate the density of duodenal CgA as a biomarker for the diagnosis of IBS. Two hundred and three patients with IBS were recruited (180(More)
To the best of our knowledge, stomach antral endocrine cells have not previously been investigated in patients with irritable bowel syndrome (IBS). Thus, in the present study, 76 patients with IBS were examined (designated as IBS-total). Diarrhoea was the predominant symptom in 26 of these patients (IBS-D), while in 21 patients, the predominant symptoms(More)
Traditional visualization of real-time 2D ultrasound data is difficult to interpret, even for experienced medical personnel. To make the interpretation during the education phase easier, we enhance the visualization during liver examinations with an abstracted depiction of relevant anatomical structures, here denoted as illustrated ultrasound. The specifics(More)
Note: Also to appear in the Dagstuhl 2012 SciVis book by Springer. Please cite this paper with its arXiv citation information. Abstract Ultrasound is one of the most frequently used imaging modality in medicine. The high spatial resolution, its interactive nature and non-invasiveness makes it the first choice in many examinations. Image interpretation is(More)
2D Ultrasonography images with parallel contrast enhanced sequences for analysis constitute a rapid and inexpensive imaging technique with high temporal resolution to assess perfusion of tissue. However, motion from various influences corrupts the inter-pixel correspondences between different time frames and therefore hampers computer-assisted analysis of(More)
Several endocrine cell abnormalities have been reported in different segments of the gastrointestinal tract of patients with irritable bowel syndrome (IBS). These cells have specialized microvilli that project into the lumen; they function as sensors for the gut contents and respond to luminal stimuli (mostly ingested nutrients) by releasing hormones into(More)
In an outbreak of waterborne giardiasis where 1300 subjects were diagnosed, with Giardia lamblia, 139 continued to have abdominal symptoms of whom two of three had negative stool culture and microscopy. These were considered to have a postinfectious functional gastrointestinal disorder. We investigated visceral hypersensitivity in patients with persisting(More)
