Self-administered symptom questionnaires in patients with dyspepsia and their yield in discriminating between endoscopic diagnoses.

BACKGROUND/AIMS: Symptoms are generally considered to be poor predictors of organic findings in patients with dyspepsia. We aimed at evaluating whether specific gastrointestinal symptoms, identified by self-administered questionnaires, correlate with specific endoscopic diagnoses and discriminate organic from functional dyspepsia. METHODS: Adult patients with pain or discomfort centred in the upper abdominal region were consecutively enrolled. Patients with heartburn, acid regurgitation, or defaecation and bowel habit problems as their predominant symptoms were excluded. Three self-administered questionnaires were applied before an oesophagogastroduodenoscopy was performed. RESULTS: Among the 799 patients, 50.6% had a normal endoscopy. Endoscopic diagnoses comprised: non-erosive oesophagitis (7.5%), erosive oesophagitis (11.1%), Barrett's oesophagus (1.1%), gastritis/duodenitis (8.4%), gastric ulcer (4.5%), duodenal ulcer (8.3%), and cancer (1.3%). Non-dominant heartburn and acid regurgitation were significantly more common in patients with organic dyspepsia, whereas hunger pains and rumbling occurred more often in those with functional dyspepsia. Multivariate analyses demonstrated that younger age, female gender, high scores for hunger pain, rumbling, hard stools, low scores for heartburn, and acid regurgitation predicted functional dyspepsia. CONCLUSIONS: Self-administered questionnaires revealed differences in the symptom patterns between patients with functional and organic dyspepsia. Furthermore, the health-related well-being in patients with functional and organic dyspepsia centred was impaired to the same extent.

[Cyclosporine treatment of patients with active ulcerative colitis refractory to high-dose glucocorticoid]. / Ciclosporinbehandling af patienter med aktiv colitis ulcerosa refraktaere over for højdosis-glukokortikoid.

In around 30-40% of patients with acute severe ulcerative colitis the disease is refractory to treatment with high-dose glucocorticoids. Adding intravenous cyclosporine to the therapy in these patients has shown encouraging short-term results. Case notes of twenty-three acutely ill patients, who received intravenous cyclosporine during the period 1992 to 1998 due to failure of high-dose glucocorticoid (n = 20) or due to medical complications (n = 3) which made surgery difficult, were reviewed. Eight patients had their first episode of ulcerative colitis whereas 15 had relapse or chronic active disease. Cyclosporine (4 mg/kg/dag) was added to glucocorticoid treatment after a median of 11 days. Clinical remission was achieved in 13 patients (57%) after a median of nine days, of these five subsequently underwent surgery. Ten did not obtain remission and went to surgery. Approximately a third of acutely ill ulcerative colitis patients refractory to standard treatment with high-dose glucocorticoids will benefit from intravenous cyclosporine in the longer term.

Quantitative magnetic resonance first-pass perfusion analysis: inter- and intraobserver agreement.

Magnetic resonance first-pass (MRFP) imaging awaits longitudinal clinical trials for quantification of myocardial perfusion. The purpose of this study was to assess inter- and intraobserver agreement of this method. Seventeen MRFP studies (14 rest and 3 under adenosine-induced hyperemia) from 14 patients were acquired. Two observers visually graded study quality. Each study was subdivided into eight regions. Both observers analyzed all 17 studies (8 x 17 = 136 regions) for interobserver agreement. Each observer then analyzed 10 of the 17 studies a second time (2 x 8 x 10 = 160 regions) for intraobserver agreement. Signal intensity curves were obtained with Argus software (Siemens, Iselin, NJ). The maximum amplitude of the impulse response function (Rmax) and the change of signal intensity (deltaSImax) of the contrast bolus were determined. Intraclass correlation coefficient was used to determine intra- and interobserver agreement. The quality was good or excellent in 14 studies. Intraobserver agreement of Rmax and deltaSImax were good (0.85 and 0.80, n = 160). Interobserver agreement of Rmax was fair (0.55, n = 136) but improved after exclusion of poor-quality studies (0.88, n = 112). Interobserver agreement of deltaSImax was good (0.73) and improved less than Rmax with study quality (0.83). Interobserver agreement for Rmax in individual myocardial regions before and after exclusion of studies with poor quality changed most markedly in lateral and posterior regions (0.69 and 0.65 vs. 0.97 and 0.94), where signal-to-noise ratios were reduced compared with anteroseptal regions (p < 0.01). Analysis of MRFP images provides good intraobserver agreement. Interobserver agreement of the quantitative perfusion analysis is good under the premise of good image quality.

[Helicobacter pylori. Which patients should be examined and treated?]. / Helicobacter pylori. Hvilke patienter skal undersøges og behandles?

Research has shown Helicobacter pylori infections to be associated with a wide range of gastroduodenal diseases such as chronic gastritis, duodenal and gastric ulcers, mucosa-associated lymphoid tissue (MALT) lymphomas, and gastric cancer. Although there is no room for doubt that H pylori strains are pathogenic in humans, it would be premature to contend that all H pylori infections should be treated. The necessity of a more conservative approach is discussed in the article.
