The histopathology of 145 malignant lymphomas of the small intestine in Iraq have been studied and results compared with the clinical and immunological findings. The most common pathology was an intense mucosal lymphoplasmacytic proliferation effacing the villi and crypts partially or completely. This was either 'pure', usually of mature plasma cells limited to the lamina propria or associated with a fullblown lymphoplasmacytic lymphoma, almost always of the upper small intestine. The syndrome presented as abdominal pain, chronic diarrhoea, clubbing and, sometimes, the serological demonstration of alpha heavy chains. Other types of lymphomas were associated with 'non-specific' mucosal inflammation or follicular lymphoid hyperplasia. They were either lymphocytic, plasmacytic or lymphoblastic with 'starry sky' histiocytic reaction, representing distinct clinicopathological entities unrelated to 'alpha heavy chain disease'. Hodgkin's disease was extremely rare in this series.

Papillary lymphoid hyperplasia of the terminal ileum is a benign condition associated with abdominal pain, intussusception, and gastrointestinal hemorrhage. It appears to represent a distinct clinicopathologic entity, separate from the usual idiopathic intussusception of infancy and childhood. The lesions are reasonably well circumscribed, localized in the submucosa of the terminal ileum, and composed of lymphoid tissue with prominent germinal follicles. Management by ileocolectomy resulted in complete cure with no postoperative complications in our six cases. However, many authors recommend conservative therapy. The cause is not known but there may be some relationship between these cases and intestinal adenovirus infection.

A prospective study of 32 patients with primary upper small intestinal lymphoma in our region revealed 10 cases of alpha heavy-chain disease. Patients were mostly in the second and third decades of life and males predominated. Weight loss, diarrhea, and abdominal pain were the most common complaints and clubbing the most frequent physical findings. Laboratory tests revealed a malabsorption pattern on intestinal x-rays, and malabsorption of xylose, fat, and vitamin B12 was frequently noted. Dense plasmacytic infiltrate of the lamina propria of small bowel was the most frequent pathologic finding while true neoplasm of the lymphoid system (ie, immunoblastic sarcoma) was encountered in 20% of the cases.

Ten cases of primary upper small-intestinal lymphoma associated with alpha-chain protein in serum were discovered in a prospective study of the sera of patients with immunoproliferative small-intestinal disease (IPSID). Patients were mostly young males presenting with abdominal pain, weight loss, and diarrhea and showing laboratory evidence of carbohydrate, fat, and vitamin B12 malabsorption and hypoalbuminemia. The more frequently encountered pathologic abnormality was a diffusely nodular jejunal mucosa produced by a plasmacytic infiltrate of variable cell maturity involving a varible depth of small bowel wall with or without involvement of the mesenteric or para-aortic-lymph node complex and, in one instance, the liver. A less frequent picture included circumferential ulcerative and constrictive transmural tumors of the upper small intestine produced by a malignant lymphoma with involvement of abdominal lymph nodes. Small-intestinal surface epithelial abnormalities, a dense mantle of mature plasma cells overlying the lymphoma, a pronounced follicular lymphoid hyperplasia adjacent to and at distances from the lymphoma were other features of note in our IPSID cases associated with alpha-chain protein.

The results of the radiological examination of 330 children following oral administration of barium are reported. It is pointed out that if one just takes into account the undoubted organic diseases, only a few children would benefit from the examination; in our case only 9 of them (a gastric and a duodenal ulcer, a pancreas pseudocyst, 5 hiatal hernias, and a celiac disease), i.e. 3%. This is not very satisfactory from a practical point of view. This situation improves radically when one looks for diseases usually rated as questionable: small hiatal hernia (cardiotuberositary malposition), functional disturbances of the small intestine, reactive hyperplasia of the lymphoid tissue, and chronic appendicitis. Thus we were able to offer 177 children, i.e. 53% of them, an efficacious therapy. The importance of chronic appendicitis and of functional disturbances of the small intestine as a cause of abdominal pain in children is pointed out, and their radiological symptoms are discussed. Finally the not uncommon, but not very well known disease of incomplete sigmoid volvulus is described.

The clinical, biochemical, immunological and histopathological features in a patient with alpha-chain disease are described. The patient, a 20-year-old Coloured man, presented with severe steatorrhoea, malabsorption, abdominal pain and progressive general deterioration. An heterogeneous abnormal band with IgA immunochemical specificity was detected on electrophoresis of the patient's serum and urine. This protein was identified as free alpha-chain and was present in serum, urine, saliva and jejunal juice. A jejunal mucosal biopsy specimen showed distinctive appearances associated with alpha-chain disease. Bone marrow involvement was found and abnormal lymphoid cells were seen in the circulation together with an increased B lymphocyte population derived from bone marrow. This is the third South African patient with alpha-chain disease to be diagnosed. The patient has shown a partial remission after 12 months' chemotherapy. There was rapid symptomatic response and normalisation of protein parameters which were not paralleled by an objectively discernible response as assessed by haematological examination, intestinal absorption studies and histology of the jejunal mucosa.

A 37-year-old man suffering from abdominal pain and diarrhea, was hospitalized because of abdominal discomfort. Gastroduodenal series showed multiple duodenal filling defects. Gastroduodenoscopic examination revealed numerous nodular lesions in the duodenum and biopsy specimen demonstrated nodular lymphoid hyperplasia. The serum immunoelectrophoretic pattern showed a virtual absence of IgA and IgM and a very decreased level of IgG. To our knowledge, it is the first case of hypogammaglobulinaemia with nodular hyperplasia of the small bowel, diagnosed by endoscopy and forceps biopsy.

A 66-year-old woman presented with abdominal pain and weight loss. Ultrasonography and computed tomography demonstrated a cystic lesion of the pancreas. After surgical resection, the patient's symptoms disappeared. Microscopic examination of the cyst lining showed mature, keratinizing squamous epithelium, surrounded by lymphoid tissue. Only three cases of this type of lesion, called "lymphoepithelial cyst", have been described previously. Histogenesis of this particular type of cyst is not well know, but can be histologically differentiated from other pancreatic cysts.

We have assessed 270 consecutive patients (age range 0.8-20 years) referred for endoscopic study because of abdominal pain during 32 months. Helicobacter pylori (HP) was detected by culture in 91 cases (33.7%). HP colonization increased significantly with age (p less than 0.01). Nine patients less than 5 years of age were colonized by HP. A previous history of peptic ulcer disease in first-degree relatives was significantly more frequent in the HP-positive group (p less than 0.001). The frequency of HP positiveness as related to diagnosis was: normal, 3.3%; nonactive chronic gastritis, 100%; active chronic gastritis, 97.2%; gastric ulcer, 75%; and duodenal ulcer, 90.9% (p less than 0.001). Endoscopic nodular antritis was a frequent (67%) and specific finding; this presence was associated with that of lymphoid follicles in the histopathological study. Signs of histological activity were observed in 55.9% of the HP-positive patients. The histological colonization by HP was assessed semiquantitatively, and a significantly greater HP colonization score was observed in patients with signs of histological activity (p less than 0.001). A significant correlation was found between HP colonization score and histological score (rs = 0.574), with a significant association between the degree of HP colonization and the histologic categories (p less than 0.001). The present study suggests a pathogenic role of HP in the development of gastroduodenal disease in children.

We found colitis in 11 of 14 children, 4 months to 7 yr after surgical diversion of the colon for chronic intestinal pseudo-obstruction. Colonoscopic examination was incidental during placement of a catheter for colon manometry and transit studies. All 14 children had complained of diffuse, poorly localized abdominal pain, but only three had a history of bloody stools. Diversion colitis had not previously been suspected in six of eight affected children without hematochezia. Biopsies showed a nonspecific acute and chronic inflammation and/or nodular lymphoid hyperplasia. There was no correlation between the duration of the colonic diversion and the severity of the colitis. Diversion colitis may be an indolent inflammatory nidus and a potential cause for repeated bacteremia, abdominal pain, and bleeding.
