Randomized Controlled Trial Comparative StudyThe comparison of dexmedetomidine and midazolam used for sedation of patients during upper endoscopy: A prospective, randomized study.
The aim of the present prospective, randomized study was to investigate and compare the safety and efficacy of dexmedetomidine versus midazolam in providing sedation for gastroscopy. A total of 50 adult patients (25 patients receiving dexmedetomidine and 25 patients receiving midazolam), 18 to 60 years of age, and rated I and II on the American Society of Anesthesiologists physical status classification system were included. A brief questionnaire was used to collect demographic data; patients were asked to rate anxiety, satisfaction with care to date and expected discomfort on a visual analogue scale. ⋯ In the midazolam group, the number of patients who had adverse effects was higher than the dexmedetomidine group (P < 0.05). As a result, dexmedetomidine performed as effectively and safely as midazolam when used as a sedative in upper gastroscopy; it was superior to midazolam with regard to retching, rate of side effects and endoscopist satisfaction. It was concluded that dexmedetomidine may be a good alternative to midazolam to sedate patients for upper endoscopy.

Randomized Controlled Trial Multicenter Study Clinical TrialA randomized trial comparing seven-day ranitidine bismuth citrate and clarithromycin dual therapy to seven-day omeprazole, clarithromycin and amoxicillin triple therapy for the eradication of Helicobacter pylori.
To assess Helicobacter pylori eradication after one week dual ranitidine bismuth citrate-clarithromycin (RBC-C) or triple omeprazole, clarithromycin and amoxicillin (OCA) therapy. ⋯ The eradication rate for the seven-day dual RBC-C regimen was lower than that for OCA.

Randomized Controlled Trial Multicenter Study Clinical TrialValidation of the GSFQ, a self-administered symptom frequency questionnaire for patients with gastroesophageal reflux disease.
Although the diagnosis of gastroesophageal reflux disease (GERD) is based primarily on symptoms experienced by a patient, relatively little attention has been paid to the development and validation of self-administered questionnaires specific to GERD symptoms. The present article presents the validation of the short, self-administered GERD Symptom Frequency Questionnaire (GSFQ). ⋯ The GSFQ is a short, self-administered, easy to use, GERD-specific questionnaire which should be considered as a useful assessment tool in the evaluation of patients with GERD and in the assessment of treatment outcomes.
