    Title Proton Pump Inhibitors and Risk of Fracture: a Systematic Review and Meta-analysis of Observational Studies.
    Date September 2011
    Journal The American Journal of Gastroenterology
    Excerpt

    Proton pump inhibitors (PPIs) are widely used in several acid-related gastrointestinal disorders. In vivo studies have suggested that gastric suppression by PPIs could result in decreased intestinal calcium absorption. Subsequently, there have been concerns that the chronic use of a PPI is associated with an increased risk of bone fracture. However, the results of clinical studies are conflicting.

    Title Eus and Survival in Patients with Pancreatic Cancer: a Population-based Study.

    There is no direct evidence that EUS improves patient outcome.

    Title Assessment of Response to Neoadjuvant Therapy in Esophageal Cancer: an Updated Systematic Review of Diagnostic Accuracy of Endoscopic Ultrasonography and Fluorodeoxyglucose Positron Emission Tomography.
    Date September 2010
    Journal Diseases of the Esophagus : Official Journal of the International Society for Diseases of the Esophagus / I.s.d.e
    Excerpt

    For assessing response to neoadjuvant therapy in patients with esophageal cancer, both endoscopic ultrasonography (EUS) and fluorodeoxyglucose positron emission tomography (FDG-PET) are commonly used, and despite few controlled trials, it is not known if one imaging modality is superior to the other. Also, relative diagnostic accuracy of early (during the course of neoadjuvant therapy) and FDG-PET after completion of neoadjuvant therapy has not been reviewed. The aim of this study was to perform a systematic review of published information to compare diagnostic accuracy of EUS and FDG-PET in this setting. A search of the MEDLINE, EMBASE, and Cochrane databases was performed along with a manual search of cross-references of eligible articles. Data on the accuracy of the imaging modalities were compared by constructing summary receiver-operating characteristic curves. Seven studies with EUS and 15 with FDG-PET were included in the final analysis (N= 966). The sensitivity of EUS and FDG-PET ranged from 20 to 100% and 42 to 100%, respectively. The specificity ranged from 36 to 100% and 27 to 100%, respectively. The areas under the curve were 0.86 (95% confidence interval [CI]: 0.77-0.96) for EUS and 0.80 (95% CI: 0.72-0.89) for FDG PET (P= 0.37). The maximum joint sensitivity and specificity (Q* index) values for EUS and FDG-PET were 0.79 (95% CI: 0.70-0.88) and 0.74 (95% CI: 0.66-0.81), respectively (P= 0.38). There was no difference in accuracy between early FDG-PET and FDG-PET after completion of neoadjuvant therapy. EUS and FDG-PET have similar overall diagnostic accuracy for assessment of response to neoadjuvant therapy in patients with esophageal cancer.

    Title Asymptomatic Pancreatic Cystic Neoplasm: a Cost-effectiveness Analysis of Different Strategies of Management.

    Excerpt

    Optimal management of asymptomatic pancreatic cystic neoplasm is not known.

    Title Diagnostic Yield of Methylene Blue Chromoendoscopy for Detecting Specialized Intestinal Metaplasia and Dysplasia in Barrett's Esophagus: a Meta-analysis.
    Date August 2009
    Journal Gastrointestinal Endoscopy
    Excerpt

    The reported yield of methylene-blue (MB) chromoendoscopy targeted biopsy in detecting specialized intestinal metaplasia (SIM) and, more importantly, dysplasia in patients with Barrett's esophagus (BE) has shown variable results.
