The objectives of this study were to determine whether the symptoms of diarrhea (defined as loose or watery stools), constipation (hard or lumpy stools), abdominal pain, and bloating occur in episodes rather than sporadically in patients with irritable bowel syndrome (IBS); to identify rules for defining the onset and termination of symptom episodes; and to assess the overlap of these episodes. ⋯ Loose/watery stools and hard/lumpy stools occur in well-defined episodes. Pain and bloating also occur in episodes, but contrary to the Rome criteria more than half of the pain episodes occur outside episodes of abnormal stool consistency.

Review Meta AnalysisDefinition, prevalence, and outcome of feeding intolerance in intensive care: a systematic review and meta-analysis.
Clinicians and researchers frequently use the phrase 'feeding intolerance' (FI) as a descriptive term in enterally fed critically ill patients. We aimed to: (1) determine what is the most accepted definition of FI; (2) estimate the prevalence of FI; and (3) evaluate whether FI is associated with important outcomes. Systematic searches of peer-reviewed publications using PubMed, MEDLINE, and Web of Science were performed with studies reporting FI extracted. ⋯ In summary, FI is inconsistently defined but appears to occur frequently. There are preliminary data indicating that FI is associated with adverse outcomes. A standard definition of FI is required to determine the accuracy of these preliminary data.

Functional abdominal pain in the context of irritable bowel syndrome (IBS) is a challenging problem for primary care physicians, gastroenterologists and pain specialists. We review the evidence for the current and future non-pharmacological and pharmacological treatment options targeting the central nervous system and the gastrointestinal tract. Cognitive interventions such as cognitive behavioral therapy and hypnotherapy have demonstrated excellent results in IBS patients, but the limited availability and labor-intensive nature limit their routine use in daily practice. ⋯ Antispasmodics, including peppermint oil, are still considered the first-line treatment for abdominal pain in IBS. Second-line therapies for diarrhea-predominant IBS include the non-absorbable antibiotic rifaximin and the 5HT3 antagonists alosetron and ramosetron, although the use of the former is restricted because of the rare risk of ischemic colitis. In laxative-resistant, constipation-predominant IBS, the chloride-secretion stimulating drugs lubiprostone and linaclotide, a guanylate cyclase C agonist that also has direct analgesic effects, reduce abdominal pain and improve the stool pattern.
