The efficacy and safety of the peripheral kappa agonist fedotozine was evaluated in a double-blind, multicenter study involving 238 patients with the irritable bowel syndrome. After a two-week washout, patients were assigned to one of four groups to receive either placebo or fedotozine three times a day at doses of 3.5, 15, or 30 mg for six weeks. Patient assessment of mean symptom intensity indicated that the 30-mg dose of fedotozine was superior to placebo in relieving maximal daily abdominal pain (P = 0.01), mean daily pain (P = 0.007), and abdominal bloating (P = 0.02). Changes in bowel function and defecation disorders could not be evaluated reliably. According to the investigators, the highest dose of fedotozine markedly reduced overall disease severity (P = 0.003) and the pain component of the symptomatic profile (P = 0.009). Clinical and laboratory safety was very good. Fedotozine 30 mg three times a day therefore appears to be effective and safe in the treatment of the abdominal pain and bloating associated with IBS.

Our objectives were to evaluate children with recurrent abdominal pain for lactose maldigestion and to assess factors which might predict lactose absorption status. One hundred thirty-seven children were referred for specialty evaluation of recurrent abdominal pain of at least three months' duration. Study subjects were evaluated by history and physical examination, dietary interviews, hematologic and biochemical laboratory testing, stool parasite examination, and radiologic or endoscopic structural examinations, as indicated. Lactose hydrogen breath testing was performed after challenge with 1 g/kg lactose 10% aqueous solution). There were 53 males and 84 females, whose ages ranged from 6 to 18 years (9.64 +/- 2.9; mean +/- SD) Lactose maldigestion was detected in 33/137 patients (24%). The prevalence of abdominal pain, bloating, gas, flatulence, diarrhea, and constipation was similar in children with or without lactose maldigestion. The perception of symptoms related to the ingestion of dairy products was similar in both groups. No other clinical parameter predicted lactose maldigestion. However, children with lactose maldigestion had overall clinical improvement with a lactose-restricted diet. Clinical evaluation alone cannot adequately predict the presence of lactose maldigestion in children. Formal evaluation for lactose maldigestion using breath hydrogen testing methods should be considered in children with recurrent abdominal pain.

This study compared daily gastrointestinal symptoms and stool characteristics across two menstrual cycles, and recalled bowel symptoms and psychological distress in women with irritable bowel syndrome (IBS, N = 22), IBS nonpatients (IBS-NP, N = 22), and controls (N = 25). Daily reports of abdominal pain, bloating, intestinal gas, constipation, and diarrhea did not differ significantly between the IBS and IBS-NP groups but both groups reported significantly higher symptoms than the control group. Stool consistencies was significantly looser in the IBS group relative to the control group. Menstrual cycle effects on symptoms were noted in all the groups. There were no significant differences in psychological distress between women with IBS and IBS-NP, but both groups reported significantly higher global distress than the control group. The lack of difference between the IBS and IBS-NP groups in contrast to the results of others, can be understood in terms of differences in recruitment strategies.

The study was undertaken to identify the presenting features of intestinal endometriosis and to evaluate its investigation and surgical management. Twenty-six cases of intestinal endometriosis were identified during a fourteen year period. The commonest site of occurrence was the rectosigmoid region (11 cases) followed by the appendix (9 cases), and ileocaecal region (6 cases). Abdominal pain was the main presenting feature in 20 cases, with associated nausea and vomiting in 12 cases and altered bowel habit in ten. Other presenting features included rectal bleeding, abdominal bloating and tenesmus. Endometriosis was not suspected preoperatively in any of the patients without a past history of this condition. Accurate preoperative diagnosis proved very difficult, with only laparoscopy providing definite evidence of intestinal endometriosis prior to formal surgery. Colonic resections were performed in 12 cases, small bowel resection in six cases and appendicectomy in nine cases, together with resection of adjacent adherent structures. This series illustrates the difficulty of establishing an accurate preoperative diagnosis, and the propensity of intestinal endometriosis to mimic other gastrointestinal diseases, particularly carcinoma and inflammatory bowel disease.

Patients are often referred for evaluation of a wide range of GI complaints including dysphagia, abdominal pain, bloating, nausea, constipation or diarrhoea. Many are diagnosed with 'functional' disease when endoscopy or conventional radiological studies fail to identify an anatomic cause for the patient's symptoms. In such cases nuclear medicine offers non-invasive methods for objectively demonstrating disease involving different areas of the gastrointestinal tract. Increasingly scintigraphy is playing a primary role in the evaluation of patients with suspected acute cholecystitis, active gastrointestinal bleeding, gastroparesis, and small and large bowel motility disorders. In addition, it supplements other studies when results are inconclusive in diagnosing oesophageal dysmotility, gastro-oesophageal reflux, acalculous cholecystitis, and postoperative complications of gastrointestinal surgery.

Our aim was to evaluate the response to intraluminal gas in irritable bowel syndrome and to determine whether this response was consequent upon disordered motility or altered perception. We evaluated 10 patients who satisfied the clinical criteria for the diagnosis of irritable bowel syndrome and 10 healthy controls. An eight-lumen perfused catheter assembly was positioned to monitor motor activity in the duodenum and proximal jejunum; a separate side port in the distal duodenum permitted gas infusion. Subjects recorded symptoms of abdominal pain, bloating, and nausea throughout the study, using a visual analog scale. Following an overnight fast and a 60-min basal recording period in the fasted state, subjects ate a standard meal; 60 min later, "sham" gas was administered for 20 min, followed by the actual infusion of nitrogen gas at 40 ml/min. Subjects were randomized to receive atropine (7 micrograms/kg) or placebo intravenously during the period of actual gas infusion. Patients with irritable bowel syndrome described more pain (score, mean +/- SE, control versus irritable bowel: 0.22 +/- 0.16 vs 1.65 +/- 0.5, P < 0.01) and nausea (0.25 +/- 0.21 vs 1.45 +/- 0.64, P < 0.04) during sham gas; motility indices were similar in both groups. During active gas, irritable bowel syndrome patients reported more pain (0.40 +/- 0.39 vs 2.94 +/- 1.16, P < 0.03); motility indices at all sites were similar in both groups. Symptom severity in irritable bowel syndrome subjects randomized to receive atropine was similar to control subjects during active gas infusion; motility indices were similar.(ABSTRACT TRUNCATED AT 250 WORDS)

The bacterial overgrowth syndrome occurs when there are alterations in intestinal anatomy, gastrointestinal motility, or a lack of gastric acid secretion. Clinically, patients present with nonspecific gastrointestinal symptoms that include abdominal pain, bloating, excessive gas production, diarrhea, weight loss, and malabsorption. The nutritional consequences of intestinal bacterial overgrowth include vitamin deficiencies, fat malabsorption, and malnutrition. The diagnosis requires a high index of clinical suspicion and can be established by specialized testing, such as the 1-gram 14C-xylose breath test. The goal of treatment is eradication of the bacterial overgrowth (usually with antibiotics) and the correction of nutritional deficiencies.

Excessive spontaneous swallowing has been associated with a variety of common gastrointestinal symptoms including abdominal pain, heartburn, and bloating and may contribute to disorders such as hiatus hernia, duodenal ulcer, and irritable bowel syndrome. The present study investigated the hypothesis that changes in emotional state alter spontaneous swallowing rate. Subjects were 38 generally healthy undergraduates assigned to either a pleasant low arousal, neutral, or aversive high arousal condition. Each experimental session was divided into 30-min baseline and arousal manipulation periods. Spontaneous swallowing rate increased significantly with emotional arousal: for low, neutral, and high arousal groups, means were 7.9 +/- 1.9 (SE), 15.8 +/- 2.4, and 23.7 +/- 3.6 swallows/30 min, respectively. Other physiological and self-report measures, used to check the effectiveness of the arousal manipulation, varied appropriately with experimental procedures. These results indicate that changes in emotional state alter spontaneous swallowing rate in generally healthy individuals. Further research with patients is needed to establish whether stress-induced increases in swallowing rate produce or exacerbate clinically significant gastrointestinal symptomatology.

Gastrointestinal motor dysfunction, intestinal pseudo-obstruction syndromes, and hollow visceral neuropathy and myopathy were previously considered functional bowel diseases but are now recognized to be organic disorders. They may alter the muscle of the intestinal wall or the nerves of the myenteric plexus, or both. Their symptoms of chronic unexplained abdominal pain, abdominal distention and bloating, early satiety, nausea, vomiting, and alternating diarrhea and constipation are the most common and perhaps the most difficult problems encountered by gastroenterologists. New intestinal recording devices assess motility and allow objective classification of neuromuscular disease, permitting accurate diagnosis and better treatment.

Early diagnosis of colorectal cancer may be delayed by the wide prevalence of gastrointestinal symptoms in the general population. This study assessed, with respect to age, the frequency of gastro-intestinal symptoms in patients with colorectal carcinoma in comparison with community controls and also compared the frequency of such symptoms between 'young' (under 70 years) and 'old' (70 year or over) subjects. Two hundred and seventy three consecutive unselected colorectal cancer patients and 273 age and sex matched community controls were interviewed in a structured manner. Among controls, the 'old' group compared with the 'young' reported abdominal pain (p < 0.05), mucous discharge (p < 0.01), faecal incontinence (p < 0.05), change in flatus production (p < 0.05) significantly more often. There were no significant differences in regularity and frequency of bowel habit by age group. All the symptoms considered were significantly more common in colorectal cancer cases than controls (except abdominal bloating), but the association was less strong in the 'old' group. This study confirms that symptoms attributable to the lower gastrointestinal tract are reported by a clinically important number of community subjects and by a significantly higher proportion of elderly people.
