Abdominal discomfort after eating cowpeas is known to be a major constraint on their greater consumption. Problems associated with cowpea consumption were identified by questionnaire in 448 randomly selected families. Some (28%) of the respondents had never experienced flatulence. Those who did said it occurred when cowpeas were eaten at all (16.7%), as dinner (42%) or without other foods (15%). A subsample of 40 people who complained of serious abdominal discomfort were fed cowpeas cooked by eight different methods at three consecutive dinners for each method. The problems reported were indigestion, vomiting, diarrhoea, increased belching, bad breath, offensive stool, flatulence, constipation, mild abdominal discomfort and sleepiness. Many respondents complained of mild abdominal discomfort with undehulled cowpeas (72.5%) and dehulled cowpeas (42.5%) that had been cooked at atmospheric pressure. Only 12.5% of the respondents complained of discomfort with dehulled cowpeas cooked under extra pressure. Thus, dehulling resulted in substantial reduction in the frequency and incidence of reported discomforts but pressure cooking also had beneficial effects, probably because of the higher cooking temperature attained.

We assessed the prevalence of Campylobacter pylori in various forms of endoscopic gastritis, including ulcer and nonulcer dyspepsia and bile gastritis and correlated it with histological evidence of inflammation. Multiple biopsy specimens were taken from 120 patients, including four normal controls, who underwent upper gastrointestinal endoscopy for evaluation of upper abdominal pain and discomfort, nausea, bilious vomiting, weight loss, and anemia. The patients included 58 men and 62 women, with a mean age of 53 years. Of these, 16 patients had gastric ulcers, 19 had duodenal ulcers, 26 had reflux gastritis (after either gastric surgery or cholecystectomy), one had a gastric polyp, one had Barrett's esophagus, and the remaining 53 had gastritis due to unspecified causes. Campylobacter-like organisms were demonstrated by light and electron microscopy in 50 of 69 patients of the nonbile gastritis group (72%) and in seven of 15 patients of the bile gastritis group (47%) (p0.05). The presence of bacteria in both groups correlated with histologically significant inflammation (particularly chronic active gastritis); similar histologic changes were noted in both major groups of nonbile gastritis and bile gastritis. Campylobacter pylori is common in all forms of gastritis in association with histologic inflammation.

An edited summary of an Interdepartmental Conference arranged by the Department of Medicine of the UCLA School of Medicine, Los Angeles. The Director of Conferences is William M. Pardridge, MD, Professor of Medicine. Several specialists have recently recognized that gastrointestinal reflux causes complications resulting in significant disease. It causes discomfort, indigestion, esophagitis, Barrett's esophagus, and carcinoma of the esophagus. Pediatricians attribute many early pulmonary problems, and even some sudden deaths in infants, to the reflux of gastric contents. Otolaryngologists now recognize that many cases of nonbacterial, nonspecific pharyngitis and laryngitis are due to the reflux of gastrc acid secretions. Contact granuloma and cancer of the larynx may, in some instances, be secondary to nocturnal reflux. Thoracic surgeons and pulmonologists believe chronic tracheobronchitis and some cases of pulmonary disease are attributable to recurrent bathing of the respiratory epithelium by aspirated gastric contents. An awareness of the many complications of gastrointestinal reflux should lead to a multidisciplined attack on the factors responsible for these diseases.

Non-specific abdominal complaints are a very frequent cause of discomfort. Even if only comparatively few are brought to the attention of the physician, they account for a considerable portion of the reasons for seeking medical care, both in acute and chronic conditions. On the other hand, few drugs are free of the suspicion of causing abdominal complaints, which make up between one-tenth and one-third of reported adverse reactions. A wide variety of possible alternative or concomitant causes makes a clear causative attribution to suspected drugs very difficult. This holds especially true for the ill-defined conditions of indigestion and anorexia. For nausea and vomiting, specific scales have been developed which facilitate differentiation between drugs causing these effects most frequently and most intensively. They have been applied in cytostatic therapy, where this is one of the most frequently encountered problems, but nausea and vomiting can seriously affect compliance in many other treatments. Somatic abdominal pain results in most instances from the irritation of the parietal peritoneum and is usually the effect of a lesion. This may or may not be caused by a drug, but this cause should be the first consideration. Visceral pain may result from functional disturbance of secretory glands or of the muscular coat, from drug action on bowel content or from irritation of the mucosa, all of which are frequently interrelated. Most frequently suspected pharmacological causes are drugs with anticholinergic action, antibiotics, potassium supplements and non-steroidal, anti-inflammatory agents. Drug-induced hyperinsulinism and porphyria are rare cases. Abuse of laxatives should always be considered because of its prevalence. A great number of other untoward drug effects have been described in the literature, but rarely merit first consideration. With the exception of promptly occurring or persistent emesis, gastrointestinal symptoms usually are not pathognomonic for drug effects and are the result of several factors. The usual approach to identifying an adverse drug effect is to delineate the functional or structural disorder, and to associate this diagnosis with possible pharmacodynamic aetiologies.

Crean et al1 defined dyspepsia as 'any form of episodic or persistent discomfort or other symptom referrable to the upper alimentary tract, excluding jaundice or bleeding', and listed irritable bowel syndrome (IBS) and formal psychiatric illnesses with gastrointestinal manifestations among the common causes of non-ulcer dyspepsias. This paper will discuss the psychiatric aspects of non-ulcer dyspepsia and will be divided into four parts: --The effects of stress and emotion on the gastrointestinal tract --Personality traits of IBS sufferers --Psychiatric disorders and non ulcer dyspepsias --Treatment strategies.

The effects of cisapride, a nondopaminolytic motility-enhancing agent, were studied in 56 patients with chronic functional dyspepsia; all had symptoms suggestive of delayed gastric emptying. The patients received 4 mg or 8 mg of cisapride or placebo orally three times daily for two successive three-week periods according to a randomized, double-blind, crossover study design. Although there was a high placebo response (55% showed good or excellent results), the global response to treatment was significantly (P = 0.024) in favor of cisapride (75% had good or excellent results). The drug was particularly superior to placebo (P = 0.03) in the improvement of a cluster of symptoms typical of postprandial discomfort, including early satiety and nausea. Side effects were minimal.

The diagnostic value of biphasic radiographic examination of the stomach and duodenum was compared with that of fiberoptic endoscopy in a prospective, blinded study of 385 patients with dyspepsia. This investigation was directed at gastric malignancies and peptic ulcers. Methodologically there is no absolute standard for a study of this kind because histologic examination is useful for detection of cancer but inadequate for ulcers. As an alternative, kappa indexes and the sensitivity and specificity, as derived by Hui and Walter, were calculated and compared. For the detection of gastric carcinoma, radiographic and endoscopic findings had almost perfect agreement beyond chance. For gastric ulcers, radiography and endoscopy had substantial agreement, which became perfect if small ulcers (less than 5 mm) were excluded. For duodenal ulcers, radiography had a lower sensitivity than endoscopy; this disagreement disappeared if small ulcers were excluded. Both methods have equal merit; choice of the initial diagnostic procedure will therefore depend on cost, discomfort to the patient, and risk of complications.

A double-blind, placebo-controlled trial was performed, using 400-mg cimetidine tablets or placebo twice daily for 4 weeks in 100 patients with non-ulcer dyspepsia (NUD) and erosive prepyloric changes (EPC) grade 2 or 3. Symptomatic assessment was made weekly and endoscopic assessment on completion of the treatment period. Symptomatically, a significant effect of cimetidine versus placebo on epigastric pain/discomfort was recorded after 2 weeks' treatment (p less than 0.05). Endoscopically, there was a significant improvement, according to our grading scale of EPC, in the cimetidine-treated group, as compared to the placebo-treated group (p less than 0.05). On the basis of our findings, patients with NUD and EPC who have epigastric pain/discomfort as a prominent symptom seem to profit from treatment with cimetidine.

Reviewing medical and epidemiological reports, no definite clinical picture could be expected as a result of a low DMF exposure and experimental research on long term toxicity has always demonstrated some adverse effects but has not been sufficient to define a no-effect level in animals. This study was designed to assess the specificity of symptoms and the relevance of adverse effects as consequence of an exposure to airborne DMF concentration in the range of the present TLV (30 mg/m3 - 10 ppm). For this purpose 100 DMF-exposed workers, with homogeneous characteristics, were compared with 100 matched controls. Both groups were selected by a careful pair-matching. Mean DMF exposure was 22 mg/m3 (range 8-58 mg/m3). Exposed subjects and their matched controls were evaluated clinically and a questionnaire was used for the registration and the comparison of subjective complaints. A laboratory assessment was performed, including transaminase and gamma-glutamyl transpeptidase. Statistical analysis was based on McNemar Test procedure. The problem of dietary alcohol intake was particularly investigated. Among symptoms studied, headache, dyspepsia and digestive impairment of hepatic type could be specifically associated with chronic DMF exposure and increased levels of gamma-GT demonstrated minimal hepato-cellular damage, even without ethanol dietary intake. No chronic sickness was diagnosed and the disturbances observed are better considered as indicators of malaise and discomfort due to a toxic effect of DMF, whose consequences are discussed.

It is hypothesized that chronic gastritis and ulcerative colitis both are induced by viral infection, and that such chronic infection of the mucosa may lead to ulceration and occasionally cancer. Duodenal ulcer disease and Crohn's disease may on the other hand, be due to activation of latent viral infection of the corresponding neural ganglions, with subsequent migration of virus along the nerves to the gut wall. The gastric acid hypersecretion often occurring in patients with duodenal ulcer disease might be a consequence of viral interference with the efferent nerve function of vagal ganglions. Correspondingly, non-ulcer dyspepsia as well as irritable colon may reflect viral infection of afferent nerve function leading to pain and discomfort.
