Randomised clinical trial: symptoms of the irritable bowel syndrome are improved by a psycho-education group intervention.

Background: Evidence supports the effectiveness of cognitive behavioural approaches in improving the symptoms of the irritable bowel syndrome (IBS). Duration, cost and resistance of many patients towards a psychological therapy have limited their acceptance.

Aim: To evaluate the effectiveness of a psycho-educational intervention on IBS symptoms.

Symptom duration in patients with irritable bowel syndrome.

Objectives: The etiology and natural history of irritable bowel syndrome (IBS) is poorly understood. We compared rectal sensory thresholds and compliance, SCL-90 scores, and follow-up questionnaires among normal controls, patients with longstanding ( > 5 y) disease (L-IBS), and patients with recent onset ( > 2 y) disease (R-IBS). The onset of symptoms in R-IBS was related to specific events such as infection (n = 10), surgery (n = 5), and stress (n = 4), but no specific event could be identified in six patients.

Sleep and duodenal motor activity in patients with severe non-ulcer dyspepsia.

The prevalence of sleep disturbances was studied in patients with severe non-ulcer dyspepsia. It was also considered if the change in sleep pattern was associated with changes in the rhythmic fasting motor activity of the gastrointestinal tract, and if motor events correlate with the patient's symptoms. Motor activity in the duodenum was monitored over a 24 hour period under freely ambulatory conditions in 10 healthy controls and in 10 patients with severe non-ulcer dyspepsia using a transnasally placed catheter with six solid state pressure transducers connected to a digital data logging device.
