We randomly surveyed 997 members of the Crohn's and Colitis Foundation of America with inflammatory bowel disease (320 ulcerative colitis and 671 Crohn's disease) in order to: (1) assess their health status, (2) compare members with ulcerative colitis and Crohn's disease, and (3) determine the correlates of health care use. Data collection included variables relating to physical and psychological symptoms, medication use, daily functional status, perceptions of health, and coping styles. The findings indicate that: (1) despite a number of symptoms and complications related to inflammatory bowel disease, the health status of this population is generally good and may be a result of effective coping styles; (2) those with Crohn's disease have more psychosocial difficulties, which appear related to greater symptom severity; (3) both psychosocial and physical health variables are related to number of physician visits, while primarily physical health variables are related to number of hospitalizations and surgeries. Further studies are needed to determine the representativeness of this self-selected sample with others having IBD. In this study, we have provided the basis for developing a more sensitive measure of health status than currently exists, and one which may have implications for future clinical studies.

Abdominal migraine is well recognised in children, but in spite of anecdotal reports migraine is not well established as a cause of abdominal pain in adults. Functional abdominal pain is usually classified as either irritable bowel syndrome or nonulcer dyspepsia, but some patients have intermittent abdominal pain associated with headache or other migraine accompaniments and, in these, a diagnosis of abdominal migraine should be considered. It is possible that some patients with functional abdominal pain have migraine presenting with few or even no migraine accompaniments. There is no nonclinical objective standard for diagnosing migraine, and research in this area is therefore very difficult. Nevertheless, some patients with functional abdominal pain may respond to antimigraine medication and, if their symptoms are suggestive, a trial of therapy may be desirable.

A model of the isolated bowel segment (IBS, Iowa Model II) was successfully created in experimental animals using a new surgical technique we developed. The IBS is completely free of its mesenteric attachment, yet its viability is preserved. The technique consists of two staged procedures: (1) initial enteropexy between the anterior margin of the liver and the antimesenteric border of the IBS with its ends forming cutaneous stomas; and (2) division of the IBS mesentery 5 weeks later. The IBS is nourished by vascular collaterals that form at the hepatoenteropexy during the interval between these two procedures. Our previous studies demonstrated preserved viability and motility in the IBS. This study was undertaken to test absorption in the IBS. In 25 rats (experimental group), the IBS (Iowa Model II) was created using an 8-cm-long isolated segment of jejunum. In 15 rats (control group), an 8-cm-long segment of jejunum was arranged to form a Thiry-Vella loop. Five weeks later, the IBS mesentery was divided in the experimental group, and sham laparotomy was performed in the control group animals. Absorption of glucose and leucine was studied in 13 rats of the experimental group and 6 of the control group using a constant single perfusion technique at 3, 8, and 11 weeks after the initial operation. The results were compared between the two groups. There was a 25% to 35% reduction in absorption of glucose and leucine in both groups with the advance of time, but no significant difference was observed between the groups except in leucine absorption at 11 weeks after the initial operation. This study concludes that absorption of glucose and leucine is preserved in the IBS after its mesentery is divided, suggesting that the IBS can be used as a functioning bowel for bowel reconstruction.

We review 28 patients with IBD (14 UC and 14 CD) diagnosed in a period of eight years (1982-1990). The age at the onset of symptoms was similar in both groups (8.1-8.7 years), but the delay in diagnosis was significantly higher in CD (16.2 months). Fever, growth retardation and oral and perianal lesions were more frequent in CD. Articular, mucocutaneous and hepatic were the more usual extraintestinal manifestations. All of them were more frequent in CD. The same comment can be made with respect to the abnormal laboratory test results. Colonoscopy including histological studies was the useful diagnostic method. An increase of the incidence of IBD it has been observed.

An increased awareness of intestinal distention or contraction is implicated in the pathogenesis of the irritable bowel syndrome. This study aimed to test this hypothesis in 20 patients with the irritable bowel syndrome and 10 controls by relating the reporting of abdominal sensations to the occurrence of the duodenal phase 3 activity front of the migrating motor complex. During prolonged recordings of interdigestive small bowel motility, subjects were asked to report any episodes of abdominal sensation they experienced. Diurnally, the rate of occurrence of abdominal sensation was significantly greater in patients with the irritable bowel syndrome than in controls (P less than 0.001); such episodes were coincident with a duodenal activity front in 9 patients with the irritable bowel syndrome and in 1 control (P less than .05). Moreover, the rate of occurrence of episodes of sensation was greater (P less than 0.01) during diurnal phase 3 activity than during diurnal phase 2 activity. When episodes were coincident with duodenal phase 3 activity, these activity fronts were of significantly greater amplitude (irritable bowel syndrome: median, 23 mm Hg) than "noncoincident" activity fronts (median, 17 mm Hg; P less than 0.05) in both patients and controls. These data strongly suggest that certain physiological small bowel motor events, if of sufficient contraction amplitude, are able to be perceived by a greater proportion of irritable bowel syndrome patients and with greater frequency than by healthy subjects. The authors conclude that the threshold for perception of intestinal contraction is lower than normal in at least some patients with the irritable bowel syndrome.

Plasma prostaglandins have been studied in 306 patients with chronic nonspecific ulcerative colitis. These were found elevated and related to the disease gravity. Treatment succeeded in normalizing prostaglandin, concentrations only in mild ulcerative colitis. In catarrhal pancolitis PGE levels moderately increased before treatment returned to normal at the end of it. In spastic colon pretreatment lack of PGF2 alpha persisted. Evaluation of plasma prostaglandins can serve an additional diagnostic procedure to improve pathogenetic therapy of chronic colitis.

Structured psychiatric interviews and psychological self-report measures were administered to 28 patients with irritable bowel syndrome and 19 patients with inflammatory bowel disease. Significantly more of the patients with irritable bowel syndrome had lifetime diagnoses of major depression, somatization disorder, generalized anxiety disorder, panic disorder, and phobic disorder. They had significantly more medically unexplained somatic symptoms, and most had suffered from psychiatric disorders, particularly anxiety disorders, before the onset of their irritable bowel symptoms.

Thirty-nine hospital outpatients with upper abdominal pain without demonstrable organic abdominal abnormalities and 28 healthy controls were compared blindly with regard to back pain and back abnormalities when subjected to a standardized physical examination of the spine. Seventy-two per cent of the patients versus 17% of the controls were troubled with back pain (P less than 0.001). Seventy-five per cent of the patients with back pain actually had abnormalities revealed at the physical examination, indicating that some organic mechanisms are involved in back pain. Most of the findings were localized to the lower thoracic and thoracolumbar segments, the same segments that innervate the upper gastrointestinal tract. This suggests the existence of a connection between abdominal pain and back pain. Viscerosomatic or somatovisceral reflexes with trigger zones either in the viscera or in the skin, muscles, tendons, or ligaments could be part of the pathophysiology in this syndrome. Fifty-one per cent of the patients had symptoms of irritable bowel syndrome, and 41% had heartburn, which was significantly related to the experience of back pain.

This report analyzes the clinical and physiological evidence supporting a role for altered visceral afferent mechanisms in the pathogenesis of two functional bowel syndromes: noncardiac chest pain and the irritable bowel syndrome. Considerable recent evidence indicates that increased contractility is present only in a minority of patients and that hypercontractile episodes are not temporally related to abdominal pain. In contrast, altered sensation and motor reflexes in response to physiological stimuli, such as mechanical distention or acid, is common when appropriately investigated. The vagal and spinal afferent innervation mediates visceral sensation and is involved in multiple reflex loops regulating gastrointestinal effector function, such as motility and secretion. Sensory input can be modulated peripherally at the afferent nerve terminal, at the level of prevertebral ganglia, the spinal cord, and the brainstem. An up-regulation of afferent mechanisms would result both in altered conscious perception of physiological stimuli and in altered motor reflexes. Current evidence is consistent with an alteration in the peripheral functioning of visceral afferents and/or in the central processing of afferent information in the etiology of altered somatovisceral sensation and motor function observed in patients with functional bowel disease.

Diarrhea is one manifestation of GI disturbance. Symptoms may be acute if caused by such things as infections, drug reactions, alterations in diet, heavy metal poisoning, or fecal impaction. Chronic diarrhea is a symptom of GI diseases such as irritable bowel syndrome, lactase deficiency, cancer of the colon, inflammatory bowel disease, and malabsorption diseases. Chronic diarrhea may also be associated with GI surgery, radiation therapy, laxative abuse, alcohol abuse, and chemotherapeutic agents. When interventions are required to deal with diarrhea, they may include such things as alteration in tube feeding products and methods of administration, fluid replacement by oral rehydration procedures, a rapid return to feeding, and education aimed at the health information clients need to prevent or control the symptom of diarrhea.
