Honey bee samples collected between 1995 and 2007 from 12 states were examined for the presence of Nosema infections. Our results showed that Nosema ceranae is a wide-spread infection of the European honey bee, Apis mellifera in the United States. The discovery of N. ceranae in bees collected a decade ago indicates that N. ceranae was transferred from its(More)
BACKGROUND With the widespread use of abdominal imaging, an incidentally found dilated common bile duct (CBD) is a common radiographic finding. The significance of a dilated CBD as a predictor of underlying disease and long-term outcome have not been well elucidated. GOALS A systematic review of studies on patients with dilated CBD was performed to(More)
Backgrounds. Limited effective palliative treatments exist for pancreatic cancer which includes surgery or chemotherapy. Radiofrequency ablation (RFA) uses high frequency alternating current to ablate diseased tissue and has been used to treat various tumors. In this study, we evaluated a prototype probe adjusted to the EUS-needle to perform EUS-RFA to(More)
Bile leaks after laparoscopic cholecystectomy are usually treated using endoscopic retrograde cholangiopancreatography (ERCP). The presence of complex, surgically altered gastrointestinal anatomy poses a diagnostic and therapeutic challenge to the endoscopic treatment of these lesions. Herein, we present a patient with Roux-en-Y gastric bypass who developed(More)
AIM To present a novel, less-invasive method of endoscopic drainage (ED) for walled-off pancreatic necrosis (WON).We describe the feasibility, success rate, and complications of combined ED extra-cavitary lavage and debridement of WON using a biliary catheter and high-flow water jet system (water pump). PATIENTS AND METHODS Endoscopic ultrasound(More)
The provisional results are presented of a comparative blind trial of iotrolan, iohexol and iopamidol for lumbar myelography. The aim of the trial was to assess the relative safety, tolerance and radiologic efficacy of the media. From the data available to date the incidence of side effects is similar for all three substances. Iotrolan does not provide(More)
Background. Current methods to diagnose malignant biliary strictures are of low sensitivity. Probe-based confocal laser endomicroscopy (pCLE) is a new approach that can be used to evaluate in vivo histopathology of the GI tract. This paper is of studies evidencing pCLE's application in the diagnosis of indeterminate biliary strictures. Methods. This paper(More)
158 replies to a questionnaire suggest that many British surgeons remain wary of using trans-uretero-ureterostomy, fearing to risk the opposite ureter and kidney or preferring to use a Boari flap or other operation. 141 (27 personal and 114 reported) cases are surveyed. 56 simple Y-anastomoses performed by 27 surgeons gave very good results, with only 4(More)
