Objective: To assess the effect of a multidisciplinary approach on the outcome of treatment for hepatitis C virus infection.
Methods: This retrospective study was conducted at the gastroenterology division by primary care providers at Phoenix VA Healthcare system in Phoenix, Arizona, United States, and comprised clinical and laboratory data of all hepatitis C patients treated between November 2002 and December 2006. The patients were clinically evaluated to determine whether they were candidates for treatment with pegylated interferon a-2a or a-2b plus ribavirin.

Aim: To compare the yield of adenomas between narrow band imaging and white light when using high definition/magnification.
Methods: This prospective, non-randomized comparative study was performed at the endoscopy unit of veteran affairs medical center in Phoenix, Arizona. Consecutive patients undergoing first average risk colorectal cancer screening colonoscopy were selected.
Background: EGD is the gold standard for the screening and surveillance of esophageal varices. A less invasive, safer and sedationless alternative procedure is needed.
Objective: To assess the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) as well as the beyond the chance agreement (kappa index), of string capsule endoscopy (SCE) in the diagnosis of esophageal varices.
Aims: Disaster and bioterrorism preparedness is poorly integrated into the curricula of internal medicine residency programs. Given that victims may present to a variety of healthcare venues, including primary care practices, inpatient hospital wards, and intensive care units, we developed a curriculum to address this need.
Methods: The curriculum consisted of four didactic sessions with supplemental readings covering biologic, chemical, and radiologic agents, as well as public health infrastructure.

Background: Dysphagia is a contraindication for the use of conventional capsule endoscopy (CE). Because string CE (SCE) allows for the immediate retrieval of the device, it eliminates the risk of capsule retention.
Objective: To assess the yield and safety of SCE in patients with dysphagia.
