In the adult, the irritable bowel syndrome is characterized by intestinal transit disorders associated or not with chronic abdominal pain. Two different forms can be seen: in one, pain and constipation are predominant, while in the other, pain and diarrhea alternate. The second form is encountered with predilection in the child. Various terms can be used to name the syndrome including colitis, non specific or benign colitis, irritable bowel syndrome in the child, infantile diarrhea, and others, all of which attests to our ignorance of the pathophysiology of this disorder. This syndrome is by far the most frequent cause of chronic or recurrent diarrhea in the child. Before the age of 3 or 4 years, the principal syndrome is diarrhea, which usually appears before the age of 6 months. Onset is generally brutal, as in acute enteritis or an extradigestive infection (ENT...) but persists, or else, more often, the syndrome appears insidiously over several days. The child has soft or liquid stools of fetid odor in most cases, very rarely sourish, inhomogeneous and in which intact aliments can be found. Stools are often associated with mucous discharge, rarely with blood, and do not contain any pus. Stools are not fatty but occasionally they are sticky and adhere to the pot. During the day, stools change from well formed in the morning to soft in the evening. Their frequency varies from one day to another as well as during a given 24 hour period, ranging from one or two to 10 per day.(ABSTRACT TRUNCATED AT 250 WORDS)

A double-blind, randomized parallel group trial comparison involving 712 patients with irritable bowel syndrome was performed. Over a treatment period of 4 weeks hyoscine-N-butylbromide (30 mg/day p.o.) plus paracetamol (1 500 mg/day p.o.), hyoscine-N-butylbromide (30 mg/day p.o.), paracetamol (1. 500 mg/day p.o.) or placebo (3 tablets/day p.o.) were administered. Patients kept a diary and entered a daily rating of their symptoms (visual analogue scale). At the end of the four weeks 81% of the patients in the Buscopan plus group were deemed "responder" (marked or some improvement in symptoms). In the Buscopan group 76%, in the paracetamol group 72% and in the placebo group 64% of the patients were responders. The differences between the Buscopan plus group and the placebo group, and between the Buscopan group and the placebo group were statistically significant. The daily rating on the analogue scale showed a statistically significant improvement in abdominal pain intensity in the Buscopan plus group versus the placebo group and in the Buscopan plus group versus the paracetamol group. Thirty-eight patients ( = 5%, no differences between the treatment groups) experienced adverse effects, that did not require treatment. Buscopan plus and Buscopan are suitable for the treatment of the irritable bowel syndromes.

Irritable bowel syndrome represent the most common gastrointestinal disease. It is characterized by abdominal pain, distension and abnormalities of intestinal transit. It is a functional disorder determined by emotional stress and by diet. The treatment is polyvalent, dietary, medicinal and psychological. In the medicinal domain the anti-spasmodics (anti-nicotinic and musculotropic), represent the first choice weapons in association or not with an anxiolytic, an anti-depressor, even an antalgic in the acute phase.

Nineteen of 27 patients suffering from Irritable Bowel Syndrome (IBS) who had completed a multicomponent treatment involving progressive muscle relaxation, thermal biofeedback, cognitive therapy and IBS education were located and evaluated 4 yr posttreatment. Seventeen of 19 (89.5, or 63% of the total original sample) rated themselves as more than 50% improved. Six of the 12 patients (50%) who submitted symptom monitoring diaries met our criteria for clinical improvement, i.e. achieving at least a 50% reduction in primary IBS symptom scores. The means on all measures at long-term follow-up were lower than those obtained prior to treatment. When follow-up symptom means were compared with pretreatment means, significant (P less than 0.05) reductions were obtained on abdominal pain/tenderness, diarrhea, nausea, and flatulence.

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.

In order to develop a scoring system for selecting patients at high risk of organic diseases of the colon, who would need a colonoscopy or a barium enema, we conducted a study with 14 GPs in the local health care district of Modena. Over one year, 254 consecutive patients who consulted their GP for chronic abdominal pain were asked to answer a guided questionnaire. A checklist of simple parameters suggestive of the presence of organic diseases of the colon was also registered by the GP. For the final diagnosis, the patients underwent either a colonoscopy or a barium enema. Data collected were analysed by means of a stepwise logistic regression analysis to obtain a weighted score for the diagnosis of either irritable bowel syndrome (score less than 0) or organic disease (score greater than 0). Out of the 25 parameters explored, six were significantly more common among patients with organic disease and weighted as positive score (namely ESR greater than 17 mm, first hour, history of blood in the stool, leukocytosis greater than 10,000 cm3, age greater than 45 years, slight fever and presence of neoplastic colonic diseases in first-degree relatives). On the contrary, five parameters were more frequent among patients with irritable bowel syndrome and weighted as negative score (namely visible distension of the abdomen, feeling of distension, presence of irritable bowel syndrome in first degree relatives, flatulence and irregularities of bowel movement). Our scoring system correctly classified 83.5% of the cases, and it was very sensitive (82.4%) for the diagnosis of organic disease.(ABSTRACT TRUNCATED AT 250 WORDS)

The objective of this prospective study was to test the hypothesis that 6 reportedly important psychosocial factors were useful criteria for diagnosing the irritable bowel syndrome. Ninety-seven new patients with entry complaints of abdominal pain, altered bowel habits, or both underwent full evaluation by board-certified or -eligible gastroenterologists in an outpatient setting. The independent measures were 6 questionnaires concerning anxiety, depression, stress, lack of social support, somatization, and abnormal illness behavior. The dependent measure, irritable bowel syndrome, was defined as the absence of an organic disease explanation for patients' entry complaints. Two other board-certified gastroenterologists, independent of the study, made this determination. Their rating was based on full review of transcripts of patients' clinic visits, laboratory data, and the results of a 9-mo telephone follow-up to patients and their physicians. Sixty-five percent of the sample had no organic disease explanation for the entry symptoms, thereby representing irritable bowel syndrome. The psychosocial predictors did not show a significant association with irritable bowel syndrome; the power of the study was 0.86. Post hoc analysis revealed that patients with organic disease, as well as patients with irritable bowel syndrome, had significantly more (p less than 0.01) psychosocial abnormality than normal subjects, which likely contributed to the inability of the psychosocial predictors to distinguish irritable bowel syndrome from organic disease. It was concluded that psychosocial criteria were of limited value in differentiating irritable bowel syndrome from organic disease but that they were determinants of health care seeking for the entire study group.

Continuous 72-h recordings of duodenojejunal contractile activity were obtained from 20 freely ambulant subjects; pressure was detected by two strain-gauge sensors incorporated in a transnasal catheter attached to an encoder and a miniature tape recorder. The subjects were 12 patients with irritable bowel syndrome, 6 of whom were constipation predominant and 6 of whom were diarrhea predominant, and 8 healthy controls. The procedure was well tolerated by all subjects and did not interfere with sleep or normal activity. In all subjects, the diurnal migrating motor complex cycle was characterized by a brief phase 1 and a prolonged phase 2; this was reversed during sleep when phase 2 was virtually absent. All subjects showed a circadian variation in migrating motor complex propagation velocity, and there was no difference in the patterns of motor activity during sleep between any of the groups. During the day, the duration of postprandial motor activity was shorter in irritable bowel syndrome patients than in controls, and diurnal migrating motor complex intervals were shorter in diarrhea-predominant than in constipation-predominant irritable bowel syndrome. In 11 of 12 inflammatory bowel syndrome patients, episodes of clustered contractions recurring at 0.9-min intervals were noted; these episodes had a mean duration of 46 min and were often associated with transient abdominal pain and discomfort. In both groups of irritable bowel syndrome patients, defecation was significantly (p less than 0.01) prolonged with a greater number of voluntary abdominal contractions (p less than 0.01) than in controls. Prolonged ambulant monitoring of proximal bowel motor activity in subjects who are free to move, eat, and sleep as they choose has, for the first time, clearly defined the striking difference in motility between the sleeping and waking state and shown that abnormalities associated with irritable bowel syndrome are confined to the latter.

Many women report that bowel symptoms are associated with menstruation, but neither the prevalence of these complaints nor their physiological basis is known. This study aimed to estimate prevalence, to determine whether patients with irritable bowel syndrome are more likely to make such complaints, and to determine whether bowel complaints during menstruation are attributable to psychological traits such as increased somatization. To estimate prevalence, 369 clients of Planned Parenthood of Maryland were asked whether gas, diarrhea, or constipation occurred during menstruation. These subjects were compared with women referred to a gastroenterology clinic and found to have irritable bowel syndrome or functional bowel disorder (abdominal pain plus altered bowel habits but not satisfying restrictive criteria for irritable bowel syndrome). Thirty-four percent of 233 Planned Parenthood clients who denied symptoms of irritable bowel syndrome or functional bowel disorder reported that menstruation was associated with one or more bowel symptoms. Gastroenterology clinic patients with irritable bowel syndrome were significantly more likely to experience exacerbations of each of these bowel symptoms, but especially increased bowel gas. Self-reports of bowel symptoms during menstruation were not associated with psychological traits or with menses-related changes in affect.

The importance of personality traits in nonulcer dyspepsia and irritable bowel syndrome is a controversial issue. We wished to assess the distribution of abnormal personality traits in nonulcer dyspepsia and the irritable bowel syndrome, define any relation among personality and symptoms, and determine whether personality factors discriminate among patients with functional, psychiatric, or organic gastrointestinal diseases. Patients with nonulcer dyspepsia (n = 31), irritable bowel syndrome (n = 67), organic gastrointestinal disease (n = 64), somatoform disorder (n = 36) and healthy controls (n = 128) were studied. Before diagnostic evaluation by an independent physician, all patients completed the Minnesota Multiphasic Personality Inventory and a symptom questionnaire. Symptom scores for abdominal pain and the Manning criteria, which is considered to be diagnostic for the irritable bowel syndrome, were evaluated. Personality scales in patients with nonulcer dyspepsia, irritable bowel syndrome, and organic disease were very similar. However, patients in the other groups differed from somatoform disorder on nearly all scales. In nonulcer dyspepsia, irritable bowel syndrome, and organic disease, hypochondriasis weakly correlated with pain. Subgroups of irritable bowel syndrome patients with predominant constipation and those with predominant diarrhea had similar personality traits, although hypomania was minimally increased in constipation. Patients who fulfilled the Manning criteria for irritable bowel syndrome had more psychological distress than those who did not. The Minnesota Multiphasic Personality Inventory correctly classified somatoform disorder and health 81% and 75% of the time, respectively, but it classified nonulcer dyspepsia and irritable bowel syndrome correctly in only 32% and 34% of cases. Our results suggest that psychopathology may not be the major explanation for functional gastrointestinal disorders.
