Systemic vasculitis is known to affect the gastrointestinal tract but the nature of the complication is poorly characterized. Out of 65 patients with systemic vasculitis, the majority of whom had renal disease, the intestine was found to be affected in 18. These comprised four of eight patients with polyarteritis nodosa, nine of seventeen with microscopic polyarteritis, four of thirty-six with Wegener's granulomatosis and one of four with Churg-Strauss syndrome. The features included abdominal pain (85 per cent), diarrhoea (50 per cent), gut haemorrhage (44 per cent) and abnormal liver function tests (50 per cent). Manifestations of gastrointestinal disease were evident at presentation in half the patients and led to a fetal outcome in five. Ileus, mucosal abnormalities, perforation and slow transit were evident radiographically, and selective visceral angiography showed aneurysms or organ infarcts in five patients. Histological assessment of gut biopsies (chiefly rectal) revealed non-specific inflammation or ulceration in nine patients and intramucosal haemorrhage in two. Focal areas of necrosis and ulceration in colonoscopic biopsies were highly suggestive of vasculitis whereas arteritis was only found in one full thickness biopsy. Hence the diagnosis of gastrointestinal complications depends largely on clinical evidence. In patients who survived, the gastrointestinal features remitted as the systemic illness improved following treatment with steroids, cyclophosphamide or plasma exchange.

Atropine sulfate was given at 2 dosages (0.044 mg/kg, 0.176 mg/kg) to clinically normal ponies in order to evaluate the drug's effect on the gastrointestinal tract. Intestinal motility, as assessed by ausculation of borborygmus, was stopped 30 minutes after injection, but it gradually returned to normal within 12 hours. Signs of abdominal pain developed in 3 of 10 ponies. In 3 clinical cases of gastrointestinal disorder, prior atropine treatment was confusing to the diagnostician and resulted in delayed surgical treatment in 1 case. It was concluded that atropine should not be used for alleviation of intestinal spasm of horses.

A total of 658 cases of campylobacter enteritis was reported in South Australia in the 18 months from March, 1980. Although Campylobacter sp. may cause more gastrointestinal disease than Salmonella sp. during some time periods, our data suggest that the reverse applies over all. However, since campylobacter enteritis tends to affect older persons who possibly are investigated less frequently, the relative prevalence of campylobacter infection may have been understated. Both diseases are notified among preschoolers to a disproportionate extent; however, Campylobacter sp. show a greater predisposition that Salmonella sp. for affecting teenagers and young adults. Persons with campylobacter infection are more likely to be residents of metropolitan areas than their counterparts with salmonella enteritis. Virtually all persons with campylobacter infection experience some diarrhoea; three-quarters have abdominal pain; approximately one-third report blood, and a similar proportion mucus in their stools. Children are more likely than adults to have mucus, and possibly blood, in their stools.

Symptoms of functional gastrointestinal disorder were sought by a questionnaire administered to 301 apparently healthy subjects in young, middle-aged, and elderly categories. Abdominal pain, a feeling of incomplete evaculation after defecation, urgency, scybala, runny stools, straining at stool, borborygmi, distension, heartburn, and laxative use were all very common. The typical symptom pattern of the spastic irritable bowel syndrome (IBS) occurred in 13.6% of subjects. Seven percent suffered noncolonic pain that was commonly associated with heartburn. A further 3.7% had painless diarrhea without the features of the spastic IBS. Six percent suffered painless constipation. Constipation seemed to increase with age. Thus four clinically distinct functional bowel syndromes existed in almost one-third of the subjects studied. Most of these had not consulted a doctor. Hospital-based studies of the IBS derive from a selected minority of patients and may not be applicable to all sufferers.

Perforation of the stomach occurring as a complication of malignant disease is a rare event. Patients often present with a prior history suggestive of benign gastrointestinal disease followed by an abrupt episode of abdominal pain. Silent perforations are unusual, but do occur. The radiographic criteria of the ulcer crater suggest benign disease in the majority of cases an it is only when there is a definitive operation the differentiation from benign disease is difficult and multiple biopsies of the ulcer are necessary. Perforation is a catastrophic complication and survival beyond one year is uncommon.

The protozoan Giardia lamblia has frequently been identified as the cause of epidemic gastrointestinal disease. Overseas travel (to both Third-World and industrialized countries), contaminated mountain streams and malfunctioning city water-supply systems are often cited as contributing factors. Giardiasis should be considered in the differential diagnosis of persistent diarrhea and other abdominal pain syndromes of unknown etiology. Aggressive diagnostic testing is required to identify the parasite. Appropriate treatment is highly successful.

Gastrointestinal disorders including abdominal pain, abdominal distention, ileus, and constipation are common after spinal cord injury. In physiologic studies of patients with spinal cord injury, slow gastric emptying, ileal dilation, and abnormal rectosigmoid motility have been found. However, it is not yet known whether abnormal gut hormone release is important in the development of these abnormalities. In healthy volunteers, there are postprandial increases in plasma peptide YY and motilin levels, which appear related to neural mechanisms. We hypothesized that abdominal sympathetic pathways provide tonic inhibition of peptide YY and motilin release and that postprandial increases in these gut hormones are mediated through spinal pathways. Fasting serum was obtained from normal volunteers, paraplegic patients, and tetraplegic patients. In studies in which patients were fed, serum was obtained from normal volunteers, paraplegic patients, and tetraplegic patients before and at 30-min intervals after a 280 kcal meal. Serum motilin and peptide YY levels were measured by radioimmunoassays. In fasting studies, there was a trend (P = 0.23) toward increased fasting serum motilin in paraplegic patients, and this result did not support tonic inhibition of motilin release. Fasting peptide YY levels were not increased in spinal cord injury patients, which did not support tonic inhibition of peptide YY release. In fed studies, there were strong trends toward postprandial increases in serum peptide YY in volunteers and paraplegic patients and a significant postprandial rise in serum peptide YY in tetraplegic patients (P = 0.04). This was evidence against involvement of spinal pathways in postprandial release of peptide YY.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical examination of the equine patient with acute abdominal pain should identify the affected body system and yield a provisional diagnosis. Determination of signalment, history, physical examination, and basic laboratory tests should assist in classification of the gastrointestinal disorder and direct the therapeutic plan. Determination of the definitive diagnosis of abdominal pain based on clinical examination is not crucial. For a successful outcome, efforts should be directed toward early recognition of the need for surgery and treatment of cardiovascular compromise in horses with severe gastrointestinal disease.

Children with HIV disease and gastrointestinal disease should be evaluated for enteric pathogens. Bacterial, protozoal, and viral agents can cause chronic diarrhea, abdominal pain, gastrointestinal bleeding, and contribute to growth retardation. This article presents an approach to the evaluation of the HIV-infected child with gastrointestinal symptoms. Therapeutic and nutritional interventions are discussed with emphasis on the multidisciplinary approach required to initiate successful management.
