Polyarteritis in the older child is thought to be a rare disease. This study describes 11 children, 3 to 12 years of age, with polyarteritis seen over a five-year period. Fever, abdominal pain, hypertension, and leukocytosis were found in almost all. Renal disease occurred in eight. Examination of muscle, gut, or kidney tissue was an effective means of diagnosis. The pathological changes were the same as those seen in adults. There seemed to be an association between polyarteritis and group A streptococcal infection. Ten patients had a salutary response to high-dose prednisone administration.

Patients' assessment of whole gut irrigation via a nasogastric tube has been obtained by a questionnaire answered by 79 of 99 patients who received this method of bowel preparation before operation on the large bowel or colonoscopy. Abdominal pain during the irrigation was experienced by 13 patients (17 per cent) and nausea and vomiting occurred in 24 (30 per cent). Intubation with a nasogastric tube and the discomfort of prolonged sitting on a commode were considered the most disagreeable aspects of the procedure. Fifty-six patients (71 per cent) would have agreed to the irrigation being repeated if necessary and many patients preferred whole gut irrigation to previous 'orthodox' bowel preparations that they had experienced.

Eosinophilic gastroenteritis is an uncommon condition affecting one or more segments of the gastrointestinal tract, mainly the stomach and small bowell, the principal changes being a variable degree of both oedema and eosinophilic infiltration. Occurring at any age it is commonest in the third decade, is often associated with abdominal pain and peripheral blood eosinophilia, and responds to steroids: allergy or asthma occurs in some 25% of patients. The oedema and eosinophilia involve the submucosa generally but any layer of the gut may be affected. The aetiology is discussed: no allergic or other cause has been determined and it is probable that further knowledge of the role of the eosinophil may be necessary before the precise nature of the lesion can be understood. An association of eosinophilic gastroenteritis with malabsorptive or protein-losing enteropathies is noted.

Four cases of enterolith obstruction in horses aged from six to 14 years are reported. All four cases had symptoms of persistent low grade abdominal pain and anorexia with an absence of defaecation. Examination revealed reduced gut motility and accumulation of gas, but heart and respiratory rates, rectal temperatures and complete blood counts were all within normal limits. Enteroliths of varying sizes were removed from the region of the transverse colon in all four horses.

Histoplasma capsulatum involves some part of the gastrointestinal tract in 75% of patients with disseminated disease, but clinically obvious gastrointestinal involvement is infrequent. Symptoms include crampy abdominal pain, diarrhea, nasopharyngeal ulcers, and rectal ulcers. Granulomatous constrictive lesions may simulate either carcinoma anywhere in the gut or less commonly Crohn's disease. We describe a patient and discuss gastrointestinal histoplasmosis.

Sites in the gut that are related to pain are reviewed with respect to the special psychophysiological factors that operate locally. Topics considered are the irritable bowel, appendicitis and appendicectomy, duodenal ulceration and biliary disorders. Psychological states that promote the complaint or experience of abdominal pain are discussed. Possible psychological mechanisms are considered for abdominal pain with the reservation that we still do not know even the main physical mechanisms of pain related to gut disturbance.

Details of 13 new cases of inflammatory fibroid polyp of the gastrointestinal tract and of 76 patients recorded in the literature (total 89) are described and analysed. The lesion is always benign, may occur at any age but is commonest in the sixth and seventh decades, and involves the stomach most frequently. Abdominal pain, often related to obstruction, is the principal symptom. Eosinophilia of the peripheral blood does not occur. The lesions are sessile or polypoidal, originate in the gut submucosa, vary greatly in cellularity, and have a wide range of tissue eosinophilia. Some are very vascular, many of the larger vessels having a notably broad zone of connective tissue about them. The aetiology of the condition is discussed and reasons for distinguishing it from eosinophilic gastroenteritis, with which it is frequently confused, are given. The precise nature and aetiology of the inflammatory fibroid polyp remains undetermined.

The clinical and histopathologic features in seven patients with intestinal lymphoma are reported. Three of these presented with ulcerative jejunitis and four with overt lymphomas. A short history of abdominal pain with weight loss followed by intestinal obstruction, hemorrhage, or perforation characterized all the patients except one in whom a nine year history of malabsorption preceded the acute phase of the disease. Malabsorption was demonstrated in four of the patients, and all showed villous atrophy with crypt hyperplasia of the jejunum remote from areas of ulceration or frank lymphoma. The malignant lymphoma cells showed varying degrees of pleomorphism and exhibited phagocytosis of platelets, red cells, and cell debris. The accompanying infiltrate of inflammatory cells often overshadowed the neoplastic histiocytes, and in those cases showing little pleomorphism these cells could be easily overlooked. In the intestine the tumor cells were usually present as a diffuse infiltrate in the lamina propria or within the bases of ulcers and in five of seven cases did not give rise to macroscopic tumor masses. In all patients dissemination of tumor cells to the lymph nodes, liver, spleen, and bone marrow was evident, the infiltrate in all these organs resembling that seen in malignant histiocytosis. The morphology of the tumor cells, their phagocytic nature, the diffuse character of the tumor infiltrate, and the pattern of dissemination suggest that this lesion should be designated malignant histiocytosis of the intestine rather than histiocytic lymphoma (reticulum cell sarcoma). It is suggested that the tumor may arise from cells of monocyte-histiocyte lineage normally present in the lamina propria of the gut and that a prolonged cryptic phase accompanied, and often overshadowed, by an inflammatory reaction may give rise to malabsorption and ulcerative jejunitis before overt lymphoma is manifest.

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.

86 plain films of the abdomen from 63 patients with acute mesenteric infarction were compared with plain films of 90 patients with acute abdomen of different origin. The airless abdomen, the increased thickness of the gut wall and the hairpin sign proved tbe nonspecific, but more pronounced and more frequent in mesenteric infarction. Gas in the gut wall and in the portal vein system was found only in mesenteric infarction. All 6 patients with gas in the portal veins died. The airless abdomen in a patient with severe abdominal pain is a surprising finding and points to the possibility of mesenteric infarction.
