Factors influencing rectal hypersensitivity in irritable bowel syndrome: A systematic review and meta-analysis.

Background: A frequent, although not universal, feature of irritable bowel syndrome (IBS) is heightened sensitivity to mechanical stimulation of the rectum, termed rectal hypersensitivity (RH). Differences in RH-based on sex, IBS subtype, IBS diagnostic criteria and age of population studied are incompletely understood. We aimed to determine whether IBS population had lower pain thresholds than healthy controls.

Rectal Hypersensitivity in Inflammatory Bowel Disease: A Systematic Review and Meta-analysis.

Abdominal pain is a key symptom of inflammatory bowel disease (IBD), particularly in active IBD, but also occurs in patients with quiescent disease suggesting that mechanisms other than active inflammation may be responsible. Putative hypothesis to explain chronic abdominal pain in patients with quiescent IBD includes crossover with irritable bowel syndrome where rectal hypersensitivity is common and has pathophysiological implications. In contrast, in IBD, the role of rectal hypersensitivity has not been established.

Transcutaneous vagus nerve stimulation prevents the development of, and reverses, established oesophageal pain hypersensitivity.

Background: The vagus nerve exerts an anti-nociceptive effect on the viscera.

Aim: To investigate whether transcutaneous vagal nerve stimulation (t-VNS) prevents the development of and/or reverses established visceral hypersensitivity in a validated model of acid-induced oesophageal pain.

Methods: Before and after a 30-minute infusion of 0.

How the Internet influences the relationship between outpatients and gastroenterologists: A multicenter study.

Background/aims: The Internet offers a lot of non-filtered medical information which may interfere with the patient-doctor relationship. The aim of the present study was to assess the influence of the Internet on the classical doctor-patient relationship in gastroenterological outpatient settings.

Materials And Methods: A multicenter study was conducted, including a representative sample selected from five major regional medical centers throughout Romania.

The anatomical basis for transcutaneous auricular vagus nerve stimulation.

The array of end organ innervations of the vagus nerve, coupled with increased basic science evidence, has led to vagus nerve stimulation (VNS) being explored as a management option in a number of clinical disorders, such as heart failure, migraine and inflammatory bowel disease. Both invasive (surgically implanted) and non-invasive (transcutaneous) techniques of VNS exist. Transcutaneous VNS (tVNS) delivery systems rely on the cutaneous distribution of vagal afferents, either at the external ear (auricular branch of the vagus nerve) or at the neck (cervical branch of the vagus nerve), thus obviating the need for surgical implantation of a VNS delivery device and facilitating further investigations across a wide range of uses.
