ABSTRACT
The features on barium enema of ischaemic colitis is characteristic and the radiological sign of "thumb printing" thought to be almost pathognomonic of the condition. We report a case of inflammatory bowel disease, probably Crohn's disease mimicking these radiological features. This has not to our knowledge been previously documented.

The purpose of this study was to determine if pirenzepine and cimetidine given together was superior to cimetidine alone in inducing healing of refractory duodenal ulcers which remained unhealed after treatment with cimetidine or ranitidine for at least eight weeks. One hundred and thirty one patients from six centres were randomised to receive either cimetidine (C) 800 mg daily or cimetidine 800 mg plus pirenzepine (C + P) 100 mg daily under double blind conditions for six weeks. The healing rate was similar in both groups, irrespective of the method of calculation. On an intent-to-treat analysis, healing was: C 66%, C + P 57%, and amongst the patients who completed treatment, healing was 70% in both groups. Patients on C and on C + P experienced a similar decrease in daytime and in night time pain. Side effects of treatment, notably dry mouth and blurred vision, were reported more often by patients on combination therapy. Combined treatment with cimetidine plus pirenzepine in patients with refractory duodenal ulcer is unlikely to be beneficial.

We report a patient with severe Crohn's disease and the short bowel syndrome on parenteral feeding who was not responding to conventional therapy and underwent treatment with cyclosporin (CyA) given initially intravenously and subsequently orally in each of two courses. Plasma drug concentrations were largely kept within the therapeutic range but wide variability was observed on oral therapy. Improvement both clinically and by objective assessment, was observed on intravenous CyA therapy, but was not sustained when the drug was given orally for several months. None of the side effects observed resisted treatment or was severe enough to warrant discontinuation of therapy. These findings suggest that there may be a place for intravenous CyA therapy in patients with severe Crohn's disease who do not respond to conventional therapy or to oral treatment with CyA.

Parotid function tests were performed on 12 patients with pancreatic insufficiency due to chronic pancreatitis. The concentrations of sodium and bicarbonate in stimulated parotid juice were reduced compared to controls (p less than 0.001). The secretion of 75Se-selenomethionine by the parotid salivary gland and exocrine pancreas following a Lundh test meal was measured in 12 patients with normal pancreatic function and 16 patients with exocrine pancreatic insufficiency. Eight of these patients had chronic pancreatitis both parotid and pancreatic secretion of the isotope were impaired. In pancreatic carcinoma the pancreatic excretion was impaired with no significant impairment of parotid secretion. The combined pancreatic/parotid radio-selenium test may be useful in differentiating between chronic pancreatitis and pancreatic carcinoma as the cause of pancreatic insufficiency.

A single oral dose of 4-46 mmol calcium gluconate at pH 5-6 was administered intragastrically to 15 male volunteers without gastrointestinal disease. There was a significant rise in acid output from 30-90 minutes after the calcium was given compared with the basal hourly collection. The serum gastrin level 30 minutes after calcium administration was significantly raised, but no correlation could be demonstrated between the acid and gastrin responses. Serum calcium levels were unchanged throughout. An equimolar dose of magnesium sulphate had no such effects. This study suggests that the intragastric administration of calcium results in independent release of gastric acid and gastrin from the gastric mucosa.

Pancreatic function was investigated in 43 patients using a combination of conventional and subtraction scans of the pancreas and duodenal aspiration of the 75Se-Selenomethionine injected, in the time periods 60-150 minutes, 90-120 minutes and 105-150 minutes after injection. Patients with chronic alcoholism, chronic pancreatitis, pancreatic carcinoma, extrahepatic biliary obstruction and liver disease were included. Seven patients with no evidence of gastro-intestinal disease served as controls. Pancreatic scanning provided eight false positive and two false negative results (23.3%) and with 75Se-Selenomethionine excretion at 105-150 minutes, six false results were obtained (14%). In only one patient was a false positive result obtained with both scans and the 75Se-Selenomethionine test. The performance of conventional and subtraction scans of the pancreas with measurement of 75Se-Selenomethionine activity in the duodenal aspirate collected from 105-150 minutes after injection provides a convenient means of testing pancreatic exocrine function in a single three hour session.

Peroheme 40, a chemical test for occult blood in faeces, has been assessed by comparing it with results obtained using 51Cr labelled red cells. The study was carried out in two parts. Initially testing was carried out on 75 stool samples from 20 patients on a restricted diet, and in the second part, testing was performed on 40 samples from 10 patients on a normal ward diet. All patients were suspected of losing blood from the gastrointestinal tract. On the restricted diet there were 29 per cent false positive and 13 per cent false negative results, while on the normal diet, there were 86 per cent false positive and 8 per cent false negative results. Peroheme-40 has therefore been shown, on a restricted diet, to compare favourably with previously available chemical tests.

Gastric mucosal biopsy specimens from 241 patients with examined. Chronic inflammatory cellular infiltration of the gastric mucosa was found in 181 patients and this graded as mild, moderate or severe. The presence or absence of atrophy or intestinal metaplasia was noted. True superficial gastritis was observed in only three cases.
