    Notes: Abstract Pathophysiologic mechanisms responsible for severe chronic constipation are poorly understood. In particular, most of the published studies have lumped together patients having different subtypes of constipation, with different and often conflicting results. We studied six patients complaining of severe idiopathic constipation and displaying homogeneous clinical and pathophysiologic features (i.e.,patients with slow-transit type constipation) to evaluate their myoelectric spiking responses to food ingestion. Ten healthy subjects acted as controls. The constipated patients failed to show the increase in myoelectric spiking activity that was seen in controls immediately following the meals, suggesting the possibility of a neurogenic defect in this condition.

    Notes: Abstract In a multicenter study of patients with painful functional bowel disorders (FBD), we compared the demographic, health status, and diagnostic features of patients with FBD and developed a functional bowel disorder severity index (FBDSI) for research and clinical care. Two hundred seventy patients with FBD in the United States, England, and Canada were surveyed on symptoms and health status, and their physicians made a diagnosis and rated illness severity as mild, moderate, or severe. Comparisons of 22 demographic and clinical variables were made by study site in addition to physicians' severity ratings. To develop the FBDSI, multiple regression analysis used the demographic and clinical variables to predict the physician's rating of severity. We found that most health status measures of patients with FBD across study sites are comparable and the derived and validated FBDSI scoring system uses three easy to obtain variables: FBDSI = [current pain by visual analog scale (0–100)] + [diagnosis of chronic functional abdominal pain (0 if absent and 106 if present)] + [number of physicians visits over previous six months × 11]. The FBDSI can be used to select patients for research protocols and/or follow their clinical outcome or response to treatments over time.

    Notes: Abstract The aims of this study were to determine the impact of irritable bowel syndrome on quality of life using a well-standardized measure, the SF-36, and to determine whether apparent impairments may be due to neuroticism. Undergraduate students with irritable bowel syndrome who had consulted a physician (41 females, 42 males), students with irritable bowel who had not consulted a physician (91 females, 74 males), and asymptomatic controls (52 females, 70 males) completed questionnaires on quality of life, neuroticism, and psychological distress. Patients showed greater impairment in quality of life than nonconsulters, who in turn showed greater impairment than controls. Neuroticism and psychological distress were correlated with all quality-of-life measures. However, when neuroticism and psychological distress were statistically partialed out, irritable bowel syndrome still had a significant negative impact. The SF-36 may be a useful outcome measure in treatment studies, but investigators will need to correct for confounding influences of neuroticism.

    Notes: Abstract To examine the applicability across subgroups of the Manning criteria commonly used to diagnose the irritable bowel syndrome, a 22-item symptom questionnaire was administered to male and female African-American and Caucasian adults (N=1344). Principal components factor analysis with varimax rotation was used to identify symptom clusters. Consistent with the findings of a previous factor analytic study, three of the six Manning symptoms (loose stools and more frequent bowel movements with onset of pain, pain relieved by defecation) formed a cluster corresponding to the irritable bowel syndrome in all subgroups. It is concluded that: (1) The three core Manning symptoms have equal applicability to both genders and to African-Americans as well as to Caucasians. They are useful symptom criteria for the diagnosis of IBS when used in conjunction with medical evaluation. (2) Three of the six Manning symptoms rarely correlate with the others; if confirmed in patient samples, this would indicate that these three symptoms are not useful for making a diagnosis of the irritable bowel syndrome.

    Notes: Abstract Biofeedback has had a greater impact on gastroenterology than on any other medical subspeciality. Biofeedback is the treatment of choice for many of the most common types of fecal incontinence, and preliminary studies suggest that it is likely to become a preferred method for treating patients with constipation related to inability to relax the striated pelvic floor muscles during defecation. This dysfunction may account for up to 50% of patients with chronic constipation. Thermal biofeedback forms part of a multicomponent behavioral treatment for irritable bowel syndrome that is reported to be effective, and other promising applications of biofeedback for gastrointestinal disorders are under investigation.
