Randomized Controlled Trial Multicenter StudyRandomized trial of rifabutin-based triple therapy and high-dose dual therapy for rescue treatment of Helicobacter pylori resistant to both metronidazole and clarithromycin.
The clinical management of Helicobacter pylori infected patients who failed standard eradication therapies remains a challenge. ⋯ Triple therapy with esomeprazole, rifabutin and amoxicillin and high-dose omeprazole/amoxicillin are comparable and effective and safe for rescue therapy of H. pylori regardless of the patient's CYP2C19 genotype.

ReviewReview article: moderate sedation for endoscopy: sedation regimens for non-anaesthesiologists.
Moderate sedation is a drug-induced depression of consciousness during which patients respond purposefully to verbal commands with or without light tactile stimulation. Moderate sedation is typically accepted in the anaesthesia community as an appropriate target for sedation by non-anaesthesiologists. ⋯ Moderate sedation provides a safety margin when compared with deep sedation and general anaesthesia. Development of protocols that target agents such as propofol to moderate sedation will expand the sedation agents available to non-anaesthesiologists and help ensure that this expansion occurs safely.

Utility of red flag symptom exclusions in the diagnosis of irritable bowel syndrome.
Studies suggest that the positive predictive value of the Rome II criteria for diagnosing irritable bowel syndrome can be enhanced by excluding red flag symptoms suggestive of organic diseases. ⋯ Red flags may be useful for identifying patients who require additional diagnostic evaluation, but incorporating them into the Rome criteria would not improve sensitivity and would result in too many missed irritable bowel syndrome diagnoses.
