Levels of vasoactive intestinal polypeptide (VIP) were measured by radioimmunoassay in plasma or tissue from thirty-five patients with watery diarrhoea, and in plasma of twenty-five normal controls. Plasma levels were between 0.6 and 11.0 ng/ml in thirty-one of the thirty-three patients in whom it was measured and too low to measure (less than 200 pg/ml) in the other two. Peptide levels were less than 200 pg/ml in twenty-three of the controls, but higher in the remaining two. All tissues from patients were "rich" in VIP (10 ng to 35 microgram per g). The aetiologic diagnoses included pancreatic islet-cell adenoma or adenocarcinoma, islet-cell hyperplasia, bronchogenic carcinoma, pheochromocytoma, ganglioneuroblastoma, medullary thyroid carcinoma, and retroperitoneal histiocytoma. The findings support the conclusions that: (1) VIP is a likely mediator of the water-diarrhoea syndrome; (2) the syndrome may result from a variety of tumours; (3) this or a related peptide hormone may be secreted by these tumours; and (4) these tumours may have a common embryonic origin.

The actions of the vasoactive intestinal polypeptide make it a potential candidate for mediating certain manifestations of the watery-diarrhea syndrome. Peptide levels were measured by radioimmunoassay in 25 controls and 30 patients with chronic watery diarrhea. Plasma levels were too low to measure (smaller 200 pg per milliliter) in 22 of the controls, averaging 79 plus or minus 64 pg per milliliter (S.D.). Levels were elevated in 26 of 28 plasma samples (5.1 plus or minus 2.5 ng per milliliter), and in each of 13 tissue extracts (5.1 plus or minus 10.9 mug per gram); in all, 28 patients had elevated levels in plasma or tissue or both. Thirteen patients had pancreatic islet-cell adenoma, four islet-cell hyperplasia, five bronchogenic carcinoma, and one each pheochromocytoma and ganglioneuroblastoma. The findings indicate that the peptide is a probable mediator of the watery-diarrhea syndrome, that the syndrome may result from a variety of non-pancreatic tumors, and that this or a related peptide may also be secreted by these tumors.

A patient with the Watery-Diarrhoea syndrome and episodic hypercalcaemia is reported. Plasma levels of vasoactive intestinal peptide (VIP) were elevated, and an islet cell adenoma of the pancreas was removed following which VIP levels decreased and diarrhoea ceased. During a hypercalcaemic episode, serum parathyroid hormone (PTh) levels were suppressed indicating the hypercalcaemia was independent of PTh and probably due to a direct action of VIP on calcium turnover.

A father and son each presented with severe watery diarrhea. The son was found to have a pancreatic islet-cell tumor associated with the pancreatic cholera syndrome, as well as a parathyroid adenoma. The father was found to have multiple islet-cell adenomas and the Zollinger-Ellison syndrome. Pancreatic tumor tissue from each patient contained detectable gastrin and vasoactive intestinal peptide; however, a much higher gastrin concentration was found in the tumor tissue from the father and a much higher vasoactive intestinal peptide content in the tumor tissue from the son. Thus, watery diarrhea may be mediated by different hormones in families having multiple endocrine neoplasia; the precise cause of the diarrheal syndrome should be defined to ensure the proper therapy.

The diagnostic features of Zollinger-Ellison syndrome (ZES) in patients with type I poly-endocrine adenomatosis with a gastrinoma are analysed on the basis of 11 cases. Both from a clinical (frequency of ulcer disease and of diarrhoea) and biological standpoint (hypersecretion of gastric acid, hypergastrinaemia, or results of secretin stimulation test), the characteristics of ZES are not different whether a gastrinoma is present alone or in association with involvement of other endocrine glands. However the signs may be either masked by changes related to another endocrine disorder or appear late. They should therefore be sought routinely in all patients with an endocrine disorder which might fall into the context of a type I poly-endocrine adenomatosis. The sole difficulty is the interpretation of gastric acid hypersecretion and/or hypergastrinaemia in a patient with hyperparathyroidism. In this latter case, such abnormalities are not necessarily due to ZES and may disappear after removal of the parathyroid adenoma.

Seventeen cases of colorectal polyps in the dog were seen at the Ontario Veterinary College over a 12-year period. The mean age of occurrence was 6.9 years, and males and females were almost equally affected. The Collie was the most frequently affected breed (4/17). The clinical signs were typically dyschezia, periodic intermittent diarrhea and melena, and rectal prolapse of the polyp. The histopatholic classifcation were hyperplastic polyp (1), papillary adenoma (1), tubular adenoma (4), papillotubular adenoma (10), and unclassified (1). Severe epithelial atypia, likely carcinoma in situ, was apparent in 5 of the papillotubular adenomas. Retrospective analysis of survival data after polypectomy suggested a good prognosis, but the results were inconclusive and it is possible that some of the polyps represented premalignant lesions. Large polyps (greater than 1 cm in diameter) frequently had marked epithelial atypia and were considered more likely to recur or to become malignant.

Our thirteen year experience with villous adenomas of the colon and rectum, embracing 264 patients, is reported. The average age of patients was sixty-two years with an almost equal sex distribution. Seventy-two per cent of the lesions occurred in the rectum and rectosigmoid and the most frequent symptoms were rectal bleeding and diarrhea. A positive correlation between size of adenoma and incidence of malignancy was noted. Although 55 per cent of the lesions were malignant, only 22 per cent harbored invasive carcinoma and only 10 per cent of the deaths were due to metastatic carcinoma. It is concluded that in the absence of invasive carcinoma, the clinical behavior of this tumor is relatively benign and a more conservative approach to the surgical management of this neoplasm should be encouraged.

A report from a medium-sized community hospital of 4 additional cases of hepatocellular adenoma is presented. Of these, 3 were pedunculated tumors. A 29-year-old woman, gravida 7, had been taking Enovid-E for 8 years. After 3 attacks of epigastric pain a mass was detected in her right upper abdomen. Surgical exploration revealed the mass pedunculated from the right hepatic lobe. The mass was excised. 3 years later a liver scan was normal. The histological appearance of the tissue resembled mature hepatic architecture without protal areas or bile ducts. A 34-year-old woman, gravida 4, para 2, had been taking Enovid-E for 6 years. She previously had had a partial thyroidectomy for carcinoma of the thyroid and later radical neck dissection for metastatic thyroid carcinoma. A mass was detected in the right abdomen. At operation, a pedunculated mass was found attached to the right hepatic lobe with 2 smaller nodules. All lesions were excised. The microscopic picture was similar to that of the other patient. A 24-year-old woman, gravida 4, para 3, had been taking Oracon for 1 year. Upper abdominal pain, vomiting, and diarrhea were complained of. An upper abdominal mass was present. At operation, a 9 cm mass was excised. The histology was the same as in the previous cases. A 28-year-old woman, gravida 2, para 1, had been taking Ovulen for 5 years. An abdominal mass was present. Surgical exploration revealed a nodular mass pedunculated from the left lobe of the liver. The mass was excised. Histological appearance was similar to the other 3 tumors. Of 42 other reported cases of similar tumors, the mean age was 27.3 years. About 40% had been admitted as emergency cases with hemoperitoneum. Almost 20% had complained of upper abdominal pain. A palpable mass was usually present. Multiple nodules were found in 13% of cases. For nonemergency cases, selective hepatic angiography has been a reliable method of diagnosis. The treatment has been resection of the tumor when feasible. However, regression of tumors has occurred when exogenous hormone influence ceased. The outcome has been fatal in 8 cases. The low incidence of this tumor is not considered sufficient cause to justify discontinuing use of oral contraceptives.

We report a case of tubular adenoma of the duct of Wirsung with focal villous changes. To our knowledge, this is the 13th reported case of this uncommon neoplasm and the first with a primarily tubular histologic pattern. The patient presented with abdominal pain and diarrhea and was found on endoscopic retrograde cholangiopancreaticography to have a mass in the head of the pancreas, which was confirmed by endoscopic ultrasound. Clinical and pathological features of the 12 previously reported cases are reviewed. Intraoperative testing failed to rule out adenocarcinoma which, in addition to difficulties presented by local anatomic relationships of the tumor, supports wide surgical resection as the preferred surgical solution.

Severe cardiac arrhythmias (Lown class IVa), rapid loss of physical capacity and dyspnoea on the slightest exertion occurred in a 55-year-old man with idiopathic dilated cardiomyopathy. In the preceding year he had recurrent diarrhoea and lost 23 kg in weight. He was found to have hypercalcaemia (3-3.2 mmol/l). The heart failure significantly improved under treatment with twice daily 12.5 mg captopril, 100 mg spironolactone daily, furosemide 40 mg twice daily, and digitoxin 0.07 mg daily. The arrhythmia responded to verapamil 80 mg and quinidine 160 mg, both drugs three times daily. Primary hyperparathyroidism was found to be the cause of the hypercalcaemia (parathormone 84 pmol/l). After the parathyroid adenoma had been removed the patient's condition again improved markedly. There were only rare monotopic extrasystoles, cardiac size regressed, and diuretics were no longer necessary. His medication at present is verapamil (80 mg three times daily), captopril (12.5 mg three times daily) and digitoxin (0.07 mg daily). It is concluded that the hypercalcaemia influenced the severity of the cardiomyopathy. It would seem that both intra- and extracellular calcium homoeostasis is of great importance in dilated cardiomyopathy.
