Following oral cholecystography in 100 patients, the conventional "fatty meal" was replaced by an intramuscular injection of Ceruletid in a dose of 0.4 microgram/kg body weight. The synthetic decapetide Ceruletid is a substance with a hormone-like effect on the gastro-intestinal tract. It contracts smooth muscle in the gut and stimulates secretion in the stomach and the exocrine pancreas. Compared with other substances producing contraction which are given orally, Ceruletid acts more quickly and more powerfully in producing contraction of the gall bladder muscle. In 86% of positive cholecystograms, this resulted in satisfactory demonstration of the bile duct, 66% better than for oral substances. Many abnormalities, particularly localised adenomyomatosis, can only be diagnosed after good contraction of the gall bladder. Side effects, such as nausea, dizziness and a feeling of heat were transitory. In three patients it led to vomiting. The rapid and certain effect of Ceruletid during oral cholecystography requires reassessment of the role of intravenous cholangiography in diagnosis. Particularly amongst out-patients, with a high proportion of normal gall bladders, it is possible to complete the examination in one stage by demonstrating the bile duct with Ceruletid.

Bromocriptine, a lysergic acid derivative with a bromine atom at position 2, has been found to have unique effects on the dopamine receptors in the pituitary and central nervous system and peripherally. It is rapidly and completely absorbed from the gut and is mainly excreted in the bile and faeces. It seems to have a particular specificity for the pituitary prolactinotrophe although it does have other effects in different diseases states. In spite of the fact that it is an ergot derivative, it is remarkably free of ergot vascular side effects in the doses needed for therapeutic benefit. The most common adverse effect are nausea, vomiting and postural symptoms. These can be overcome by starting at low doses and increasing the therapeutic levels. Its major use is in the suppression of prolactin in states where this hormone is elevated irrespective of cause. It has also been used in the treatment of acromegaly and is under investigation for use in other disease states probably linked with prolactin system or dopaminergic receptors.

Three children aged between 7 and 11 years, after an acute onset of diarrhoea and vomiting, developed protracted diarrhoea and severe loss of weight. None had been abroad. No significant aetiological agent was found. There was evidence of acute inflammatory disease on proximal small intestinal biopsy, and some evidence of more widespread gut involvement--of the rectum in Cases 1 and 2, and the terminal ileum in Cases 2 and 3. The disease resolved spontaneously and without relapse.

In this review I have described the pathophysiology of allergic disorders of the gastrointestinal tract. Situations where the intestine cannot be a complete barrier to foreign allergens and antigens were discussed and etiological factors of gastrointestinal allergy were detailed. Clinical features of gastrointestinal allergy include diarrhea, vomiting, abdominal pain and colic, intestinal hemorrhage and malabsorption as well as symptoms and signs outside the gastrointestinal tract such as chronic rhinitis and asthma in the respiratory system, urticaria, angioedema and eczema as dermatological signs, headache, insomnia, hyperkinesis as central nervous system manifestations, failure to thrive and anaphylaxis as constitutional reactions. Milk allergy was discussed as an example of food allergy. Immunology of the gastrointestinal tract was presented, with examples of four types of hypersensitivity reactions, and gastrointestinal disturbances of immunodeficiency disorders and syndromes were named. Lastly, the autoimmune mechanism and the gut were described, with particular discussion of ulcerative colitis as an example of an autoimmune disease.

Mecillinam is a new antibiotic related to the penicillins but more active than ampicillin against salmonellae, including Salmonella typhi. Mecillinam must be administered parenterally, but the ester, pivmecillinam, is absorbed from the gut. Eight patients suffering from typhoid fever and one suffering from paratyphoid fever were treated with the antibiotic, and seven responded satisfactorily. One patient could not tolerate pivmecillinam because of vomiting but there were no other adverse reactions. Serum and bile levels of mecillinam were many times the minimum inhibitory concentrations for most salmonellae. The antibiotic is a promising addition to the agents available for treating typhoid.

Large numbers of a reovirus-like agent were visualized with electron microscopy in bacteria-free gut homogenates obtained from piglets with a fatal diarrhea resembling transmissible gastroenteritis. The syndrome, of vomiting, diarrhea, dehydration, and death, was reproduced in piglets artificially infected with these bacteria-free gut homogenates. Reovirus-like particles persisted in serial piglet passage and none was seen in uninfected, asymptomatic controls. Hyperimmune sera (made in recovered piglets) aggregated the reovirus-like particles, as judged by immunoelectron microscopy, and neutralized the infectious agent. The cytoplasm in enterocytes on infected intestinal epithelium fluoresced when this hyperimmune sera was used in an indirect fluorescent antibody test. Feeding cow colostrum or diets containing porcine gamma globulin protected infected piglets. No cytopathogenic effect was noted in infected tissue cultures, nor did this agent affect neonatal guinea pigs, hamsters, mice, and rats. The agent did not agglutinate human O or A erythrocytes.

The metabolism of serotonin was studied in cancer patients of their first day of their first course of chemotherapeutic drugs either with strongly or moderately emetogenic regimens. It was observed that strongly emetogenic treatments induce greater increases in serotonin release than moderately emetogenic regimens. High-dose cisplatinum (75 +/- 5 or 83.8 +/- 5 mg m-2) produced a marked increase in the plasma levels and in the urinary excretion of 5-hydroxyindole acetic acid (5-HIAA). Neither platelet nor plasma (platelet-free plasma) serotonin were significantly modified by high-dose cisplatinum. Dacarbazine (283 +/- 22 mg m-2), another strongly emetogenic agent, induced acute nausea and emesis paralleled by marked increases in the urinary excretion of 5-HIAA. Both for high-dose cisplatinum and dacarbazine, the increases in serotonin metabolism occurred with a similar time-course than those of vomiting, and lasted for a period of 4 to 8 h. Low-dose cisplatinum (30.8 +/- 3 mg m-2) as well as cyclophosphamide-based chemotherapies (520 +/- 30 mg m-2) produced very small increases in the urinary excretion of 5-HIAA. Platelet and plasma serotonin levels failed to increase in cyclophosphamide-treated patients. Octreotide, a long-acting somatostatin analog, did not inhibit the increase in urinary 5-HIAA and the nausea and vomiting produced by high-dose cisplatinum. These results suggest that for treatments that induce marked increases in serotonin release such as high-dose cisplatinum or dacarbazine: (a) the amount and time course of serotonin release induced by chemotherapeutic drugs determines the severity, time of onset and pattern of emesis observed; (b) platelet serotonin play no role in chemotherapy-induced emesis; (c) strongly emetogenic regimens release serotonin from enterochromaffin cells; and (d) intestinal release of serotonin is the consequence of the damage induced by the chemotherapeutic drugs on the gut mucosa.

Motility-like dyspepsia, a clinical subgroup of functional dyspepsia, refers to the cluster of symptoms which suggests an underlying motility disturbance of the upper gut. Characteristic symptoms, in addition to upper abdominal pain or discomfort, are nausea, vomiting, early satiety, anorexia, postprandial abdominal bloating and excessive repetitive postprandial belching. Patients with concomitant symptoms of irritable bowel syndrome are currently excluded from this clinical entity. Delayed gastric emptying of solids and/or liquids, postprandial antral hypomotility and antroduodenal incoordination, gastric myoelectrical arrhythmias and dysfunction of visceral afferents are the major alterations in upper gut sensorimotor activity which have been described. An empirical trial of medical therapy is warranted if there are no "alarm" symptoms at presentation. If symptoms are not relieved after 2-4 weeks, then investigations of the upper gastrointestinal tract, preferably by endoscopy, to exclude the presence of organic disease, is advisable. Management approaches are then reassurance, dietary manipulations and attention to psychosocial aspects. Prokinetic agents appear to be useful as short-term medical therapy in some patients, but optimum long-term treatment strategies, including the use of medications which may improve a diminished tolerance to gut distension, are not established.

Intestinal malrotation may be complicated by volvulus and intestinal necrosis. One hundred two children (64 male, 38 female) undergoing surgical abdominal exploration from 1977 to 1987 had malrotation. Fifty-two patients were less than 7 days of age, 13 from 8 to 30 days, 26 from 31 to 365 days, and 11 were older than 1 year of age. Of infants, 39 of 65 had 40-week gestations, 18 of 65 had 36- to 39-week gestations, and 8 of 65 had less than 36-week gestations. Chief symptomatology included: bilious emesis (47), intestinal obstruction (19), abdominal pain (11), and bloody stools (7). Seventy patients had congenital anomalies (50 single, 20 multiple). Diagnostic evaluations included 56 upper gastrointestinal series and 27 barium enemas. Each patient underwent correction of malrotation and appendectomy, and correction of congenital anomalies (omphalocele-9, gastroschisis-6, diaphragmatic hernia-7). Complications included short gut (2), sepsis (5), feeding difficulties (2), pneumonia (3), small bowel obstruction (2), and other (15). Nine patients (8.8%) died (trisomy 18-1, trisomy 13-1, intestinal necrosis-3, hepatic failure-1, prematurity-1, other sepsis-2). Two hundred sixteen children with intestinal malrotation have been treated from 1937 to 1987. Mortality rate has improved from 23% to 2.9%.
