Chronic constipation: A critical review
No full textAbstractChronic constipation is a very common symptom that is rarely associated with life-threatening diseases, but has a substantial impact on patient quality of life and consumption of healthcare resources. Despite the large number of affected patients and the social relevance of the condition, no cost-effectiveness analysis has been made of any diagnostic or therapeutic algorithm, and there are few data comparing different diagnostic and therapeutic approaches in the long term. In this scenario, increasing emphasis has been placed on demonstrating that a number of older and new therapeutic options are effective in treating chronic constipation in well-performed randomised controlled trials, but there is still debate as to when these therapeutic options should be included in diagnostic and therapeutic algorithms. The aim of this review is to perform a critical evaluation of the current diagnostic and therapeutic options available for adult patients with chronic constipation in order to identify a rational patient approach; furthermore we attempt to clarify some of the more controversial points to aid clinicians in managing this symptom in a more efficacious and cost-effective manner
Objective correlates of the symptom of bowel urgency in patients with irritable bowel sindrome
No full textHigh spontaneous chromosomal damage in lymphocytes from patients with hereditary megaduodenum
No full textChromosomal aberration and micronucleus assays were used to investigate the extent of cytogenetic damage in peripheral blood lymphocytes from four patients in two unrelated families with hereditary megaduodenum. The frequencies of total chromosomal aberrations, which significantly correlated with those of micronuclei, were higher in the patients than in sex- and age-matched controls, with no overlapping between the two groups. The considerable chromosomal fragility in patients with hereditary megaduodenum may be a genotypic marker for preclinical diagnosis predictive of increased cancer risk

Discrepancy between recalled and recorded bowel habits in irritable bowel syndrome
No full textBACKGROUND: A discrepancy between recalled and recorded bowel habit subtypes has been reported in irritable bowel syndrome (IBS), but the reasons for it remain unclear.
AIM: To assess the agreement between recalled and recorded bowel habit subtypes; to determine whether any discrepancy is related to stool form variability or psychological factors; and to test the correlations of recalled and recorded stool form with colonic transit time.
METHODS: Bowel habit subtype was established in 54 IBS patients at the enrolment visit (recalled) and with the aid of diary cards (recorded). Colonic transit time, the variability of stool form and the patients' psychological profiles were also recorded.
RESULTS: Recalled and recorded bowel habit subtypes agreed in only 54% of the patients (kappa = 0.28). Stool form variability was greater among the patients whose recalled and recorded bowel habit subtypes were discordant (P = 0.03), whereas the psychological profiles were not different. Colonic transit time significantly correlated with stool form only when it was recorded on diary cards.
CONCLUSION: The discrepancy between recalled and recorded bowel habits in IBS patients is related more to stool form variability than an altered psychological profile. Diary cards should be used to ensure that stool form reflects colonic transit time
"Pseudotumoral” hepatic pattern in acute alcoholic hepatitis : a case report
No full textIn acute alcoholic hepatitis (AAH), a "pseudotumoral" appearance of the liver parenchyma on computed tomography (CT) scan has been reported. The main findings are hypervascularized areas closely similar to those observed in large hepatocellular carcinomas. We report a case of a patient affected by AAH with an unusual appearance of these "pseudotumoral" areas on CT scan, close resembling a metastatic cancer rather than a primary hepatocellular carcinoma. In fact, in contrast with previous reports, the picture was characterized by the presence of many inhomogeneous, hypoattenuated areas highlighted during both pre- and post-contrast phases. Moreover, we report the first description of "pseudotumoral" lesions on ultrasound scan. This patient was successfully treated with corticosteroids, even if many controversies still exist regarding their efficacy in this setting
