Oral domperidone (30 mg/day) or placebo tablets were given to 41 patients presenting with symptoms of chronic post-prandial dyspepsia, in a double blind study. The tablets were taken three times a day before meals. The first part of the study lasted four weeks and was followed by a second four week period in which domperidone was given on an open basis to all subjects. At the end of the double-blind phase all indices but one (bitter regurgitation) as well as the gastro-oesophageal reflux cluster had significantly improved on domperidone treatment while none had done so on placebo. During the subsequent open four weeks of domperidone all items improved in both study groups. No side effects were seen in any of the participants in the study.

A doubld-blind crossover study of oral domperidone (10 mg t.d.s.) involving 48 patients suffering from chronic postprandial dyspepsia, showed a significant relief of symptoms on active treatment compared to placebo. The trial lasted eight weeks, the crossover in medication taking place at four weeks. Side effects were rare and mild and it is concluded that domperidone could be a very useful drug for the symptomatic treatment of upper gastrointestinal distress.

Forty patients who were suffering from chronic dyspepsia, diagnosed clinically and radiologically as being related to delayed gastric emptying, were treated with either domperidone or placebo in a double-blind trial. The trial lasted four weeks and the dose of domperidone was 10 mg orally t.d.s. before meals. The results showed that the drug markedly improved symptoms and that side effects were few, being recorded in one patient only, on active treatment. It is concluded that domperidone is a useful agent for the treatment of dyspepsia with retarded gastric emptying.

Techniques for computer-assisted diagnosis have been largely confined to off-line use, and there has been little examination of their potential role directly in the clinical setting. It is argued that the potential benefits of on-line diagnostic aids are considerable. A major barrier to such developments is uncertainty that the practical use of an on-line system would lead to the improvements in diagnostic effectiveness that more conventional off-line systems have already demonstrated. A series of studies in which clinicians took the histories of computer-simulated 'patients' presenting with dyspepsia, and formed diagnoses on the basis of these histories with and without computer assistance, suggested that diagnostic effectiveness may be greatly improved with on-line computer assistance. Some reasons for this improvement are discussed and it is concluded that the clinician and the on-line computer bring different but complementary types of knowledge to the diagnostic task. Though many practical questions remain to be answered the findings establish the principle of on-line symptom processing.

A double-blind trial compared diclofenac with placebo in 44 outpatients. On from each group dropped out with dyspepsia, and one (placebo group) with ineffective treatment. Twenty completers received diclofenac. Dosage was one tablet (25 mg diclofenac) three times daily during the first week. In the second (final) week, most patients had four or six tablets. Diclofenac had significantly greater effect on pain, grip, morning stiffness, joint tenderness and swelling, and in comparison to previous treatments, even though the placebo group required significantly more rescue anaglesic. A few patients in each group had slight dyspepsia. One in the active and six in the placebo group complained of minor central nervous system symptoms. There were no serious side-effects. Haematological, biochemical and urinary analyses showed no clinically important changes. It is concluded that, in the short term, diclofenac (Voltarol) is effective in relieving the symptoms of inflammatory polyarthritis. It is well tolerated as placebo medication, and had no detrimental haematological or biochemical effects.

Pirenzepine (PRZ, 75 mg/day for 10 days followed by 50 mg/day for 20 days) was compared with placebo (PL) in the treatment of endoscopically confirmed active gastroduodenitis or duodenal ulcer and with carbenoxolone (CB, 300 mg/day followed by 200 mg/day) in the treatment of gastric ulcer in a 30-day double-blind clinical trial. Ninety-seven of 112 outpatients completed the trial. The results can be summarized as follows: a) Gastroduodenitis. Complete normalization of the endoscopic picture was observed in 61% of the 28 patients on PRZ and in 30% of the 27 on PL. b) Duodenal ulcer. Complete endoscopic healing was observed in 75% of the 12 patients on PRZ and in 44% of the 9 on PL. In both studied PRZ induced improvement in clinical symptoms in more patients than PL. c) Gastric ulcer. PRZ and CB induced complete healing in a similar percentage of patients (64% of 11 and 70% of 10 patients). Better results in dyspepsia were observed in the PRZ group than the CB group. No major side-effects and no pathological changes in blood and urine analyses were observed in PRZ-treated patients.

Macaca mulatta monkeys were immunized orally with polyvalent Boivin extract of Shigella flexneri 2a, 3a, 4a, 4b, 6 and Shigella sonnei. The total immumizing dose for each component was equivalent to 1.2 X 10(12) cells. After challenge with 7.5 X 10(10) cells of a virulent S. flexneri 2a strain, out of 20 immunized animals 2 developed dysentery and 4 showed mild dyspepsia; all 6 control animals became ill with dysentery. Vaccination failed to influence the incidence, duration or the intermittent character of shigella excretion. Protective antibodies appeared in high titre in the serum of immunized animals.

During a 7-year period proximal gastric vagotomy (PGV) was performed in 565 patients. Of these, 210 patients with duodenal ulcer and 14 with dyspepsia without demonstrable ulcer at the time of operation were followed for 5--7 years. Sixty-six percent are symptom-free (Visick I), 23% have no complaints when they take certain dietary measures (Visick II), 3% are improved but still have periods of dyspepsia (Visick III), and 8% are failures because of recurrent ulcer (Visick IV). There were 4 duodenal, 3 pyloric, 5 prepyloric, and 7 lesser-curve gastric recurrences. There were one operative death (0.2%) and one major complication (0.2%). The side effects after PGV are mild, infrequent, and seldom of any significance to the patients. Diarrhoea and dumping are virtually eliminated. Body weight was stable during the whole period of study, and blood chemistry did not disclose any deficiency in haemoglobin, serum iron, or vitamin B12 which might be attributed to PGV. It is concluded that 5--7 years after proximal gastric vagotomy for duodenal ulcer there is a 10% recurrence rate, but the low risk of death and of severe complications and the lack of significant side effects more than outweight the high recurrence rate.

Gastric surgery may be followed by mechanical postoperative problems, usually due to impaired gastric emptying or the afferent loop syndrome, recurrent dyspepsia, the early or late dumping syndrome, diarrhoea, or nutritional disturbances. The pathophysiological basis of these disorders is discussed and their clinical features are briefly considered.

In a prospective study the diagnostic value of biopsy and that of brush cytology in the diagnosis of gastric cancer were compared. The patients included in the study were endoscopied because of upper abdominal dyspepsia. When the endoscopic appearance of the mucosa suggested malignancy, and in all cases in which ulcerations were seen, brush cytological smear and at least five biopsies were obtained. The cytology and the biopsy specimens were assessed by two different pathologists in a mutual blind fashion. If the result of the examination suggested or showed the presence of cancer, it was considered positive. The results were evaluated by means of sequential analysis. When 195 examinations had been included in the study, disagreement had occurred in 8 cases, in all of which the biopsy was verified as correct. This difference is significant. In 187 cases the result of the 2 tests were in agreement, but in 3 cases the result of both tests were falsely negative. It was concluded that no diagnostic advantage was gained by the addition of brush cytology to endoscopic biopsy.
