Severe rectal injury following radiation for prostatic cancer.

Between 1970 and 1981, 348 patients underwent definitive irradiation. Of these patients 6 (1.7 per cent) sustained severe rectal injury as manifest by major rectal bleeding, rectal stricture, rectal mucosal slough and rectal ulceration. Severe rectal injury was observed in 0 of 13 patients (0 per cent) treated with 125iodine, 3 of 329 (1 per cent) treated with 6,400 to 6,800 rad external irradiation, 2 of 39 (5 per cent) treated with 7,000 to 7,300 rad external irradiation, and 1 of 7 (14 per cent) treated with 198gold and external irradiation. The impact of radiation dose, radiation therapy technique and surgical trauma was assessed. Rectal injury was managed by supportive measures in 2 patients and by diverting colostomy in 3 with benefit. One patient underwent abdominoperineal resection. A small bowel fistula and an intra-abdominal abscess developed, and the patient died.

Radiation therapy in bulky seminoma.

Between 1969 and 1980, 17 patients with bulky retroperitoneal seminoma and 1 patient with bulky mediastinal seminoma were treated with radiation therapy. One patient had resection of gross retroperitoneal disease, and 1 patient had resection of gross mediastinal disease. Fifteen patients received adjuvant irradiation to the mediastinum and paraclavicular lymph nodes, and 1 patient received adjuvant chemotherapy. At last follow-up, 17 of 18 patients (94%) remain free of disease. No patient has sustained treatment-related morbidity or mortality.

Mechanisms of hydrocephalus in cerebral cysticercosis: implications for therapy.

Patients with hydrocephalus secondary to cerebral cysticercosis are a highly heterogeneous group. The mechanisms of hydrocephalus in these patients are multiple. Intraventricular cysts may be found in the 3rd and 4th ventricles, the sylvian aqueduct, and the foramen of Monro. Intraventricular cysts can be suspected when the 3rd and 4th ventricles or aqueduct remain enlarged despite shunting. Intraventricular contrast medium demonstrates the presence of the parasites. The intraventricular cysts should be removed surgically. Hydrocephalus due to cisternal cysticercosis can be diagnosed by isotope cisternography. These patients should receive shunts, but the long term prognosis is probably poor. Guidelines for the management of hydrocephalus due to cysticercosis are suggested.

Long-term ranitidine treatment for the maintenance of duodenal ulcer healing.

The purpose of the present trial was to verify the efficacy and safety of long-term ranitidine treatment (150 mg at bedtime for 1 year) for the maintenance of duodenal ulcer healing in 22 patients following a successful short-term course of therapy with ranitidine at the full dose of 300 mg per day. Of the 16 patients who completed the trial - there were 6 drop-outs - 4 suffered relapses during the year of treatment (25% cumulative recurrence rate), while remission persisted in the remaining 12 patients (75%). Biochemical tests revealed no statistically significant differences in mean fasting serum pepsinogen and trypsinogen as compared to mean basal values. Mean fasting serum gastrin showed a statistically significant rise from 156 +/- 27 S.D. to 258 +/- 110 S.D. pg/ml (p less than 0.01) only at the 12th month of therapy and rapidly returned to normal (162 +/- 34 S.D.) as soon as therapy was discontinued. No side-effects of any consequence were observed.

Gut hormone release after intestinal resection.

To investigate the possible role of gut and pancreatic hormones in the adaptive responses to gut resection, plasma concentrations of the circulating hormones were measured, in response to a test breakfast, in patients with either small or large intestinal resection and in healthy control subjects. In 18 patients with partial ileal resection a significant threefold rise was found in basal and postprandial levels of pancreatic polypeptide, a fourfold increase in motilin, and more than a twofold increase in gastrin and enteroglucagon levels compared with healthy controls. In contrast, nine patients with colonic resection had a threefold rise in levels of pancreatic polypeptide only. One or more of these peptides may have a role in stimulating the adaptive changes found after gut resection.

Pancreatic and gastrointestinal hormones in chronic pancreatitis.

Pancreatic and gut hormones have been measured in 39 patients with chronic pancreatitis, 16 of whom had severe pancreatic insufficiency. Patients with pancreatic insufficiency had significantly diminished fasting levels and postprandial rises of pancreatic polypeptide which were less than 20% of normal. Patients with chronic pancreatitis, with or without exocrine insufficiency, had two- to threefold higher plasma levels of motilin and enteroglucagon than controls. Plasma levels of insulin, pancreatic glucagon, gastric inhibitory polypeptide and gastrin were similar to normal in these patients. The pattern of response of these hormones to a test breakfast differs markedly from those seen in other gut disease states and may reflect pathophysiological mechanisms.

Findings in computerized axial tomography of tuberculous encephalopathy.

A 24 year-old woman with miliary tuberculosis of the lungs, developed a diffuse encephalopathy with signs of increased intracraneal pressure and without meningitis. A CAT scanner disclosed decreased density of the white matter and multiple nodular lesions enhanced with the infusion of contrast media. To our knowledge, this is the first description of the findings in computerized axial tomography of a patient with miliary tuberculosis and hematogenous dissemination associated to diffuse encephalopathy without meningitis.
