OBJECTIVES: To analyse the clinical course and the histopathology of primary gastrointestinal non-Hodgkin's lymphoma (GI-NHL) in adult patients and to investigate a possible impact of Helicobacter pylori. DESIGN/SETTING: Retrospective study of all adult patients in Copenhagen county diagnosed during a 6-year period with NHL. SUBJECTS: A total of 55 patients with GI-NHL diagnosed during the period from 1985 to the end of 1990. RESULTS: Twenty-eight patients had primary lymphoma in the stomach, 14 in the small intestine, 11 in the large intestine and two patients had multifocal involvement. The dominant presenting symptoms were abdominal pain, weight loss, diarrhoea, constipation and fatigue. Acute emergency problems such as severe haemorrhage or perforation at initial presentation were unusual. According to the revised European-American lymphoma (REAL) classification, diffuse large B-cell lymphoma was the most frequent histologic subtype comprising 53% of the cases. Helicobacter pylori infection was documented in 15 of 25 evaluable patients (60%) with gastric lymphomas and was not associated with any specific histological subtype. Endoscopic procedures and barium X-rays were the diagnostic approaches with highest sensitivity. In total, 30 patients (58%) achieved complete remission, 10 (19%) achieved partial remission, and 12 (23%) did not respond to treatment. The overall 5 year survival rate was 0.36 without statistically significant difference between the histological subtypes. Likewise the presence of Helicobacter pylori did not affect survival. CONCLUSION: Primary GI-NHL is a heterogeneous disease entity with considerable therapeutic controversies. No specific clinical or histologic

OBJECTIVE: This study aimed to determine if there is an abnormality of circulating gastrointestinal hormones in patients with severe idiopathic constipation. METHODS: Twelve patients, all female (median age 34 yr) and 12 healthy controls (eight female, median age 32 yr) were studied. A radioisotope-labeled solid/liquid meal was ingested, and the serum hormone response, as well as the relationship between serum hormones and rates of gastric emptying and small intestinal transit, were studied for 180 min postprandially. RESULTS: Somatostatin levels were higher in patients with constipation (basal level, controls vs patients, 31 vs 57 pmol/L, p < 0.05, median values; peak level, 48 vs 60, p < 0.05). Patients showed a significantly lower somatostatin integrated incremental meal response (2182 vs 104, p < 0.05). No correlation was found between the somatostatin levels and rates of upper gastrointestinal transit in patients. Pancreatic glucagon was significantly decreased (p=0.04). Enteroglucagon levels were significantly lower (p > 0.05) in patients between 30 and 60 min after the meal. The peak found after the meal in normal subjects was absent. Basal levels of pancreatic glucagon correlated with small bowel transit by two different measures: head of meal (r=0.69, p=0.03) and cecal filling at the time of 50% gastric emptying (r=0.84, p=0.002). No significant differences between the two groups could be found for basal and peak levels at different times and integrated incremental response to the meal for insulin, gastric inhibitory polypeptide (GIP), glucagon-like peptide-1 (GLP-1), cholecystokinin (CCK), gastrin, pancreatic polypeptide (PP), motilin, neurotensin, and peptide

PURPOSE: We determine whether functional bladder and/or bowel disorders influence the natural history or treatment of children with primary vesicoureteral reflux. MATERIALS AND METHODS: We assessed 143 children with primary vesicoureteral reflux that stopped spontaneously or was surgically corrected for functional bowel and/or bladder disorders, including bladder instability, constipation and infrequent voiding, termed the dysfunctional elimination syndromes. RESULTS: Dysfunctional elimination syndromes were present in 66 of 143 children (43%) thought to have primary vesicoureteral reflux. Of these 66 patients 54 (82%) had a breakthrough urinary tract infection and underwent reimplantation compared to only 18% without the syndromes. Of 70 children who had a breakthrough urinary tract infection dysfunctional elimination syndromes were present in 54 (77%) and absent in 16 (23%). Of the remaining 73 patients who did not have a breakthrough infection dysfunctional elimination syndromes were present in 12 (16%) and absent in 61 (84%). In children with dysfunctional elimination syndromes the resolution of reflux that was 1 grade less severe required an average of 1.6 years longer. After the disappearance of reflux, urinary tract infection developed in 18 children, including 14 (78%) with dysfunctional elimination syndromes. Unsuccessful surgical outcomes involving persistent, recurrent and contralateral reflux occurred only in children with dysfunctional elimination syndromes. CONCLUSIONS: Dysfunctional elimination syndromes are common and are often unrecognized in children with primary reflux. These syndromes are associated with delayed reflux resolution and an increased rate of breakthrough urinary tract infection, wh
