ABSTRACT
BACKGROUND AND STUDY AIMS: Colonoscopy is the cornerstone of diagnosing colonic diseases. Investigators have evaluated the effectiveness of antispasmodic agents in colonoscopy with conflicting evidence. The aim of this study is to determine the efficacy of enteric coated peppermint oil capsules (Colpermin®), an antispasmodic agent, on outcomes during colonoscopy. PATIENTS AND METHODS: A total of 80 patients undergoing elective colonoscopy were recruited and randomized in a double blinded fashion to receive either placebo or peppermint oil capsules administered 4â¯h prior to the procedure. RESULTS: Peppermint oil capsules did not affect caecal intubation time when compared with placebo. Patients' tolerance, endoscopist's satisfaction and demand on sedation were also not affected. CONCLUSION: This randomized controlled trial does not support the routine use of peppermint oil capsules prior to colonoscopy as a tool for procedure optimization, and patients' and endoscopist's satisfaction.

A total of 490 stool specimens were collected from patients with diarrhea and healthy controls without diarrhea to investigate the incidence of Bacillus cereus and its enterotoxins. B. cereus was found more significant in stools of persons with diarrhea than without diarrhea (9.5% versus 1.8%, P < 0.05), and was also detected more frequent but not significant in individuals aged > or =1 year and in adults than in children aged <1 year (11% and 8% versus 7.8%, P > 0.05). The hemolytic enterotoxin HBL genes of B. cereus isolates (hblA, hblC, hblD) were detected in 58%, 58%, and 68%, respectively, whereas the nonhemolytic enterotoxin NHE genes (nheA, nheB, nheC) were detected more frequent in 71.%, 84%, and 90% of the isolates, respectively. This study suggests that B. cereus isolates harboring 1 or more enterotoxin gene(s) can be a potential cause of diarrhea in Jordanian population.
