Subharmonic And Endoscopic Contrast Imaging Of Pancreatic Masses: A Pilot Study., Flemming Forsberg, Maria Stanczak, Andrej Lyshchik, David E. Loren, Patrick O'Kane, Ali Siddiqui, Thomas E. Kowalski, Cynthia Miller, Traci Fox, Ji-Bin Liu, John R. Eisenbrey

Department of Radiology Faculty Papers

OBJECTIVES: To use subharmonic imaging (SHI) to depict the vascularity of pancreatic masses compared to contrast-enhanced endoscopic ultrasound (EUS) and pathologic results.

METHODS: Sixteen patients scheduled for biopsy of a pancreatic mass were enrolled in an Institutional Review Board-approved study. Pulse-inversion SHI (transmitting/receiving at 2.5/1.25 MHz) was performed on a LOGIQ 9 system (GE Healthcare, Milwaukee, WI) with a 4C transducer, whereas contrast harmonic EUS (transmitting/receiving at 4.7/9.4 MHz) was performed with a radial endoscope (GF-UTC180; Olympus Corporation, Tokyo, Japan) connected to a ProSound SSD α-10 scanner (Hitachi Aloka, Tokyo, Japan). Two injections of the contrast agent Definity (Lantheus Medical …

Sex And Race And/Or Ethnicity Differences In Patients Undergoing Radiofrequency Ablation For Barrett's Esophagus: Results From The U.S. Rfa Registry., Sarina Pasricha, Nan Li, William J.

Muthusamy, Bergein F. Overholt, Nicholas J. Shaheen

Department of Medicine Faculty Papers

BACKGROUND: Little is known about differences in Barrett's esophagus (BE) characteristics by sex and race and/or ethnicity or these differences in response to radiofrequency ablation (RFA).

OBJECTIVE: We compared disease-specific characteristics, treatment efficacy, and safety outcomes by sex and race and/or ethnicity in patients treated with RFA for BE.

DESIGN: The U.S. RFA patient registry is a multicenter collaboration reporting processes and outcomes of care for patients treated with RFA for BE.

PATIENTS: Patients enrolled with BE.

INTERVENTIONS: RFA.

MAIN OUTCOME MEASUREMENTS: We assessed safety (stricture, bleeding, perforation, hospitalization), efficacy (complete eradication of intestinal metaplasia [CEIM]), complete eradication of dysplasia, …

Randomised Clinical Trial: Polyethylene Glycol 3350 With Sports Drink Vs. Polyethylene Glycol With Electrolyte Solution As Purgatives For Colonoscopy--The Incidence Of Hyponatraemia., Rebecca Matro, Constantine Daskalakis, Dan Negoianu, Leo Katz, Cassandra Henry, Michael Share, David Kastenberg

Division of Gastroenterology and Hepatology Faculty Papers

BACKGROUND: Polyethylene glycol 3350 plus sports drink (PEG-SD) is a hypo-osmotic purgative commonly used for colonoscopy, though little safety data are available.

AIM: To evaluate the effect of PEG-SD on serum sodium (Na) and other electrolytes compared with PEG-electrolyte solution (PEG-ELS).

METHODS: We performed a single center, prospective, randomised, investigator-blind comparison of PEG-ELS to PEG-SD in out-patients undergoing colonoscopy. Laboratories were obtained at baseline and immediately before and after colonoscopy. The primary endpoint was development of hyponatraemia (Na/L) the day of colonoscopy. Changes in electrolyte levels were computed as the difference between the lowest value on the day of colonoscopy …

Relative Telomere Length: A Novel Non-Invasive Biomarker For The Risk Of Non-Cirrhotic Hepatocellular Carcinoma In Patients With Chronic Hepatitis B Infection., Xiaoying Fu, Shaogui Wan, Hie-Won Hann, Md, Ronald E Myers, Phd, Richard S Hann, Jennifer Au, Bicui Chen, Jinliang Xing, Hushan Yang

Division of Gastroenterology and Hepatology Faculty Papers

BACKGROUND AND AIMS: Telomere length has emerged as a promising risk predictor of various cancers including hepatocellular carcinoma (HCC). However, the majority of studies in this area measured telomere length in hepatocytes and one in lymphocytes with conflicting results. Moreover, no studies have been reported on using circulating DNA telomere length as a non-invasive HCC biomarker.

METHODS: We conducted a nested case-control study to determine the relative telomere length (RTL) in serum DNA from 140 hepatitis B virus (HBV)-related HCC cases and 280 frequency-matched cancer-free HBV controls.

RESULTS: Cases had a significantly longer RTL (median, 0.31; range, 0.02-2.31) than controls …

Efficacy Of Morning-Only Compared With Split-Dose Polyethylene Glycol Electrolyte Solution For Afternoon Colonoscopy: A Randomized Controlled Single-Blind Study., Rebecca Matro, Md, Anastasia Shnitser, Md, Maya Spodik, Md, Constantine Daskalakis, Sc.D, Leo Katz, Md, Alexandra Murtha, Ba, David Kastenberg, Md

Division of Internal Medicine Faculty Papers & Presentations

OBJECTIVES: Administering a purgative close to the time of colonoscopy is optimal for cleansing. The aim of this study was to compare the efficacy and tolerability of morning-only (AM-only) polyethylene glycol electrolyte solution (PEG-ELS) to split-dose (PM/AM) PEG-ELS for afternoon colonoscopy.

METHODS: This was a single-center, prospective, randomized, investigator-blinded, non-inferiority study comparing AM-only to PM/AM PEG-ELS for afternoon outpatient colonoscopy. The primary end point was whole colon prep adequacy. Tolerance and polyp detection were secondary outcomes.

RESULTS: Overall, 125 patients were randomized and 9 withdrew without taking any prep. Of 116 analyzed, 62 received AM-only prep and 54 received PM/AM …

Complete Resolution Of Gastric Amyloidosis After Autologous Stem Cell Transplantation., Dinu Cherian, Kristin Braun, Neal Flomenberg, Juan P. Palazzo, David Kastenberg

Division of Gastroenterology and Hepatology Faculty Papers

A 48-year-old female with multiple myeloma (MM) and amyloidosis presented with massive upper gastrointestinal (GI) bleeding one week after autologous stem cell transplantation (autologous-SCT). Esophagogastroduodenoscopy (EGD) demonstrated necrotic, purple, pigmented, friable lesions throughout the stomach (Figure 1a), along with a bleeding ulcer in the cardia (Figure 1b, Video 1) which was successfully treated with epinephrine (1:10,000) injections. Biopsies demonstrated nodular amyloid deposition (Figures 2) which was Congo red positive. The patient had no further hematemesis and was discharged home 4 days later. Ten months after autologous-SCT, EGD revealed a normal stomach (Figure 3, Video 2) with …

Hepatitis C Risk Assessment, Testing And Referral For Treatment In Urban Primary Care: Role Of Race And Ethnicity., Stacey B. Trooskin, Victor J. Navarro, Robert J. Winn, David J. Axelrod, A. Scott Mcneal, Maricruz Velez, Steven K. Herrine, Simona Rossi

Division of Gastroenterology and Hepatology Faculty Papers

AIM: To determine rates of hepatitis C (HCV) risk factor ascertainment, testing, and referral in urban primary care practices, with particular attention to the effect of race and ethnicity.

METHODS: Retrospective chart review from four primary care sites in Philadelphia; two academic primary care practices and two community clinics was performed. Demographics, HCV risk factors, and other risk exposure information were collected.

RESULTS: Four thousand four hundred and seven charts were reviewed. Providers documented histories of injection drug use (IDU) and transfusion for less than 20% and 5% of patients, respectively. Only 55% of patients who admitted IDU were tested …
