In a prospective study, the prevalence of 15 physical symptoms and symptom groups was evaluated in 1635 cancer patients referred to a pain clinic. In addition to pain, patients suffered an average of 3.3 symptoms: insomnia (59%), anorexia (48%), constipation (33%), sweating (28%), nausea (27%), dyspnea (24%), dysphagia (20%), neuropsychiatric symptoms (20%), vomiting (20%), urinary symptoms (14%), dyspepsia (11%), paresis (10%), diarrhea (6%), pruritus (6%), and dermatological symptoms (3%). While symptom prevalence was influenced by tumor site, pain intensity, and opioid treatment, only a minor relationship was seen between symptoms and gender, age, or tumor stage. The data emphasize that it is not sufficient to simply address pain during the treatment of patients with cancer pain; a more global approach to symptom management is necessary.

In children with vomiting, dyspepsia, and feeding problems, gastroesophageal reflux (GOR) and altered gastric emptying are common. We have used electrical impedance tomography (EIT) to study children with suspected gastric emptying disorders. Abnormalities of the gastric emptying curve suggestive of GOR were seen in some, with marked negative or positive shifts related to sharp increases or decreases in intragastric resistance. These findings could represent fluid leaving or entering the stomach, as might occur in GOR. To confirm the origin of the abnormal EIT curves, we devised and in vitro tank test system, and we performed simultaneous 2-h EIT and intraoesophageal pH monitoring after a glucose meal on six patients. In vitro, reflux of > or = 25 ml produced clearly detectable changes on the emptying curves. In vivo, the overall correlation between the times of 42 GOR episodes lasting > or = 1 min detected by pH study and the times of 38 negative peaks due to > or = 15% changes of the maximum intragastric resistivity detected by simultaneous EIT was significant; the correlation was highly significant in four of six patients. When the peaks were used to define GOR episodes on EIT gastric emptying curves, the two methods still showed good agreement. Retrospective examination of 50 patients who had undergone both EIT and 24-h intraoesophageal pH study during their diagnostic workup showed that EIT had a sensitivity of 94.6% and a specificity of 76.9% (with positive and negative predictive values of 0.92 and 0.83, respectively) for the detection of pathological GOR.(ABSTRACT TRUNCATED AT 250 WORDS)

Heterotopic pancreatic tissue localized in the upper gastrointestinal (UGI) tract rarely presents with symptoms unless it is complicated by bleeding or mucosal ulceration. The case of a 26 year old man who presented with a one year history of epigastric pain, dyspepsia and several episodes of vomiting, without signs of bleeding or ulceration is reported. Work-up, which included upper gastrointestinal endoscopy, abdominal ultrasound and UGI series, revealed an intramural mass on the lesser curvature of the stomach, with normal overlying mucosa. The patient underwent surgical excision of the lesion and histologic examination showed normal pancreatic tissue. Postoperatively the patient did well with marked clinical improvement. In reviewing the literature on aberrant pancreatic lesions of the stomach the Authors discuss the varying clinical presentation and differential diagnosis as well as treatment options: when the lesions present with disabling symptoms, surgical excision should always be performed.

Anorexia, epigastric discomfort, nausea, and vomiting may result from disordered gastric motility and emptying. These features have been found in many adults with anorexia nervosa, but have never been investigated in early onset anorexia nervosa. In 14 patients with early onset anorexia nervosa (eight of whom had upper gastrointestinal tract symptoms), six children with other eating disorders, four children with non-ulcer dyspepsia, and 10 controls matched for age and sex, the non-invasive technique of surface electrogastrography was used to measure fasting and postprandial gastric antral electrical control activity, which underlies antral motility. The electrical signal was recorded by four bipolar silver/silver chloride electrodes attached to the upper abdomen, amplified and low pass filtered at 0.33 Hz before being displayed on a polygraph, digitised at 1 Hz, and stored on the hard disk of a personal computer for later offline analysis. Patients with non-ulcer dyspepsia had gastric antral dysrhythmias. No significant difference was found in the mean (SD) dominant frequency of the antral electrical control activity between patients with early onset anorexia nervosa (2.86 (0.35) cycles/minute (cpm)), patients with other eating disorders (3.14 (0.65) cpm), and controls (3.00 (0.46) cpm). The amplitude of electrical control activity increased postprandially in all but one subject and the fasting/postprandial amplitude ratio did not significantly differ between patients with early onset anorexia nervosa and controls, though patients with longer established disease had a smaller increase in amplitude. Gastric antral electrical dysrhythmias are not a feature of early onset anorexia nervosa and therefore do not induce or perpetuate food refusal in this disorder.

In 20 patients with diagnosis of functional dyspepsia due to dysmotility and/or reflux, the effectivity and tolerance of two prokinetic drugs--metochlopramide (MCP) (10 mg. three daily doses, vo) and cinitrapide (CTP) (1 mg., 3 daily doses, vo)--were assessed using a protocol of a propective and cross-sectional study after a blank period. Following the treatment with MCP and CTP, statistically significant improvements were observed in the intensity/severity of postprandial epigastric fullness, flatulence, epigastralgia, pyrosis, active regurgitations and anorexia. The MCP was more effective for the improvement of vomiting in these patients; however, the number of defecations per week increased significantly only after the CTP therapy. The therapeutical effectivity of both drugs, according to a subjective and objective global assessment was similar, with good results of 60-65% for MCP and 55-60% for CTP. Tolerance of both drugs was good. None of the patients spontaneously referred to the presence of side effects and only 3 patients (15%) treated with MCP and 2 patients (10%) treated with CTP mentioned some of the suggested side effects, which were absent before the onset of treatment. Both drugs produced an increase in the levels of Prolactine, but their average values were within the normal range. Only in two patients treated with MCP and in one patient treated with CTP, values slightly higher than the upper normal limit were observed. No significant differences were observed when comparing the results obtained with MCP therapy and CTP therapy.

In a prospective study, gastroscopy and biopsies from the gastric antrum and body were undertaken in 100 consecutive patients (67 women, 33 men; mean age 58.6 [11-90] years) with unknown Helicobacter pylori status. None had been on any bacteria-suppressing drugs. Main indications for gastroscopy were upper abdominal pain, dyspepsia, emesis and anaemia of unknown cause. The macroscopic criteria for the diagnosis of H. pylori gastritis were the presence of at least one of the following signs: (1) chronic antral erosions; (2) goose-pimple-like appearance of the antral mucosa; (3) spotty erythema in the antrum; (4) complex changes of the antral mucosa with both bizarre reddening and pale areas; and (5) increased areolar markings and diffuse or fine-spotty erythema in the mucosa of the body of the stomach. Four biopsies each from the antrum and body were examined with the urease quick-test, microscopically as smears, specific culture and histology as reference methods. 60 patients had H. pylori gastritis, recognized macroscopically in 59 (sensitivity 98.3%). A false-positive diagnosis was made in 10 of 40 H. pylori-negative patients (specificity 75%). The positive predictive value of macroscopic diagnosis was 85.5%, the negative predictive value 96.8%.

An open prospective drug monitoring study was undertaken to assess the efficacy and tolerability of 5 mg cisapride three times daily in 37,925 general practice patients with functional dyspepsia. Short-term (mean, 4 weeks) cisapride treatment was associated with a significant reduction in overall dyspeptic symptom scores and improvements in scores of all eight individual dyspeptic symptoms (epigastric discomfort, fullness, nausea, bloating, heartburn, acid regurgitation, loss of appetite, and vomiting). Physician's and patient's subjective global evaluations of antidyspeptic efficacy were good or very good in 80% to 90% of cases. The tolerability of cisapride was judged to be satisfactory, good or very good in approximately 95% of patients, with adverse drug reactions being documented in 4.8% of patients. Of these, diarrhea/loose stools (2.5% of all patients) and headache (0.7%) were most frequent. Premature treatment withdrawal due to poor tolerability was necessary in only 0.35% of patients.

Cutaneous electrogastrography was performed in nine healthy volunteers and in 43 patients presenting with various clinical conditions known to be associated with gastric motor disorders, including: 24 with functional dyspepsia, nine with longstanding diabetes mellitus, five with recent nausea/vomiting, three with pyloric stenosis, one with post-vagotomy gastroparesis, and one with idiopathic gastric distension and atony. The electrogastrography signal was recorded during 1h pre-prandial period and 1h after eating. The electrogastrography dominant frequency and power were determined using running spectral frequency analysis and the time-course of electrogastrography was evaluated in a pseudo three dimensional graphic. The electrogastrography dominant frequency was divided into four bands: 1. Bradygastria (0-2.4 cpm); 2. Normal (2.4-3.9 cpm); 3. Tachygastria (4.0-9.9 cpm); 4. Duod-resp (10.0-15.0 cpm). The percentage of the dominant electrogastrography power into those four frequency bands was determined. Electrogastrography was considered normal if functional dyspepsia was normal in more than 65% of the time. The electrogastrography was normal (dominant frequency into 3 cpm range in > 65%) in: 9/9 healthy volunteers, 3/3 pyloric stenosis, 4/5 nausea/vomiting, 3/9 diabetes mellitus, 13/24 functional dyspepsia. Gastric dysrhythmias were present in > 35% of the electrogastrography recording in: 1/5 nausea/vomiting, 11/24 functional dyspepsia, 6/9 diabetes mellitus, 1/1 post-vagotomy gastroparesis, 1/1 gastric distension and atony. Persistent tachygastria (> 10%) was found in: 1/1 gastric distension and atony (90% electrogastrography), 1/1 post-vagotomy gastroparesis, 1/5 nausea/vomiting, 6/9 diabetes mellitus, 6/24 functional dyspepsia. It was concluded that electrogastrography is a non-invasive, well-tolerated, reliable means of recording gastric myoelectric activity and gastric dysrhythmias. Patients presenting with gastric motor disorders, with chronic dyspeptic symptoms, or acute nausea may present transitory or persistent gastric dysrhythmias.

From 1990 through 1993, we treated 36 patients with recurrent typical biliary colic but who showed no ultrasonic evidence of cholelithiasis by laparoscopic cholecystectomy. Associated symptoms included nausea (75%), bloating (56%), fatty-food intolerance (53%), vomiting (17%), weight loss (31%), bowel irregularity (28%), reflux or dyspepsia (25%), and fever (17%). Diagnostic evaluation included ultrasound (100%), upper gastrointestinal series (36%), oral cholecystogram (14%), computed tomographic scan (39%), endoscopic retrograde cholangiopancreatography (17%), upper gastrointestinal endoscopy (14%), and hepatobiliary scan (92%). Quantitative hepatobiliary scans in 33 patients revealed a low gallbladder ejection fraction (EF) of less than 35% in 29 patients (88%; mean EF = 9%), and 13 patients experienced reproducible pain after cholecystokinin provocation. All patients underwent attempted laparoscopic cholecystectomy; one case of unsuspected acute acalculous cholecystitis was converted to open laparotomy because of unclear anatomy. Gross and histological examination of the gallbladders revealed chronic inflammation (83%), cholesterolosis (31%), cholesterol crystals or small stones (17%), acute inflammation (8%), polyps (6%), and normal histology (6%); however, blind retrospective scoring of gallbladders revealed significant chronic inflammation in only 38%. In the 2 to 40 months (mean, 14 months) since operation, there have been no deaths (97% follow-up). Laparoscopic cholecystectomy relieved pain in 93% of patients with a low preoperative EF compared with 75% of patients with a normal EF (nonsignificant p value). Persistent abdominal or gastrointestinal complaints included flatulence (31%), loose stools or fecal urgency (29%), belching (29%), indigestion (20%), nausea (11%), and "typical" gallbladder pain (9%). We conclude that many patients with symptoms of biliary colic and scintigraphic evidence of biliary dyskinesia have histologic findings of chronic cholecystitis. Although laparoscopic cholecystectomy usually eliminates biliary colic, persistent nonbiliary complaints are frequent.

Helicobacter pylori-like organisms (Hp) and polymorphonuclear leucocytes (PMNs) in 2614 gastroduodenal biopsies from 602 patients with dyspepsia, in Al Ain, United Arab Emirates, between October 1990 and October 1992, were histologically graded to determine the prevalence of Hp gastritis and their utilization in the evaluation of treatment efficacy in these patients. Symptoms of functional dyspepsia included, in order of frequency, abdominal pain or discomfort, flatulence, burning sensation, regurgitation, fullness, nausea, vomiting, bloating and belching. The biopsies were paraffin embedded, sectioned and stained with hematoxylin and eosin (H and E) to grade the inflammation. In addition to H and E, several special stains including modified Giemsa (MG), Wharthin-Starry silver and cold Ziehl-Neelsen stains were utilized to clearly identify Hp organisms. Giemsa method was found to be superior to other special stains in visualizing the Hp organisms in paraffin sections, and was utilized in every case. Two immunohistochemical markers for B cells (CD20) and T cells (CD45RO) were utilized for labeling lymphocytes infiltrating the lamina propria of the gastroduodenal biopsies in formalin-fixed paraffin-embedded sections. H and E and MG stained sections were utilized to count PMNs and Hp, and were graded 0, 1, 2, and 3, corresponding to none, mild, moderate, and severe grades of the Sydney system for classification of gastritis, respectively. Of the total initial 2318 endoscopic biopsies, 98.8% of the patients had suitable biopsies for histologic evaluation. Unsuitable biopsies were recovered from patients with gastric carcinoma. Inflammation was seen in 98.5% of 595 patients with suitable biopsies. In 74.5% of these patients the inflammation was active; 37.5, 32.5 and 4.5% had mild, moderate and severe active inflammation, respectively. In the remaining 24% of the 595 patients, the gastritis was chronic without activity or atrophic changes. As many as 73.6% of the patients with suitable biopsies were Hp positive; 39.8, 29.1 and 4.7% had grades 1, 2 and 3 Hp, respectively. Intestinal metaplasia was found in 28.9% of the 602 patients, and was seen more often in Hp positive than Hp negative patients (34.5 vs 14%, P < 0.005, for d.f. = 1; chi 2 = 10.35). Of the Hp positive patients, 172 and 46 patients attended the first and second follow-up endoscopy visits, respectively. The triple treatment was composed of one dose of tinidazole (2gm), doxycycline, 200 mg initial dose and 100 mg daily for two weeks, and bismuth subcitrate (Gist-Brocades nv, Delft, The Netherlands), 2 tablets twice daily for 4 weeks. After triple drug treatment, eradication of Hp was accomplished, histologically, in 38.4 and 45.7% of the patients on first and second follow-up visits, respectively. Thus, the Sydney system-based grading scale provides an objective histological evaluation of Hp gastritis for accurate prevalence studies, and may prove to be of value in estimating treatment efficacy.
