Pancreatic ductal adenocarcinoma is associated with a unique endocrinopathy distinct from type 2 diabetes mellitus.

Introduction: The majority of patients with pancreatic ductal adenocarcinoma (PC) display either impaired fasting glucose/glucose intolerance or overt diabetes. However, the pathophysiologic basis of this association remains largely unexplained.

Methods: In this case-control study we aimed to study the morphological changes in the islets of patients with PC, compared to control patients with and without type 2 diabetes mellitus (T2DM).

Dissemination of Information on Neutropenic Diet by Top US Cancer Centers: In-line with the Evidence?

The neutropenic diet is commonly prescribed to cancer patients with neutropenia with the goal of reducing infections. However, multiple randomized trials have proved no benefit with neutropenic diets compared to less restricted diets with regards to reducing infectious risk. We aimed to ascertain if top cancer centers recommended for or against the use of neutropenic diets on their official websites.

Epidemiology, Tumor Characteristics, and Survival in Patients With Primary Pancreatic Lymphoma: A Large Population-based Study Using the SEER Database.

Introduction: Primary pancreatic lymphoma (PPL) is an extranodal manifestation of non-Hodgkin lymphoma originating in the pancreas, which constitutes <1% of all pancreatic neoplasms. Because of the rarity of the disease, most data on PPL are derived from case reports and small case series. To provide better insight into the epidemiology, treatment, and outcomes of these patients, we conducted an analysis of patients with PPL from the Surveillance, Epidemiology and End Results (SEER) database, which is presented in this study.

Laparoendoscopic Transgastric Resection of Prepyloric Gastrointestinal Stromal Tumor.

This case report describes an 83-year-old woman with multiple comorbidities who presented with melena and coffee-ground emesis with diagnostic studies evident for a large prepyloric gastrointestinal stromal tumor. She underwent combined laparoendoscopic transgastric resection surgery for the tumor, performed by a team of gastroenterologist and thoracic surgeon with a successful outcome. The case and videos in this report provide a descriptive demonstration of the steps leading up to the surgical intervention followed by a step-by-step illustration of the combined surgical technique, thus highlighting the importance of multidisciplinary approach for optimal treatment of prepyloric gastrointestinal stromal tumor.

Clinical spectrum of adult patients with annular pancreas: Findings from a large single institution cohort.

Background And Aims: Annular pancreas (AnnP) is a rare congenital abnormality that results from the presence of a complete or partial ring of pancreatic tissue surrounding the descending portion of the duodenum. While the clinical presentation and management of AnnP in neonates and infants has been well described, the complete spectrum of clinical presentation of AP in adults is not very clear. We aimed to describe the clinical spectrum of presentation and management of adult patients with AnnP.

High-Grade Dysplasia in Resected Main-Duct Intraductal Papillary Mucinous Neoplasm (MD-IPMN) is Associated with an Increased Risk of Subsequent Pancreatic Cancer.

Background: There is lack of consensus on post-operative surveillance for resected non-invasive intraductal papillary neoplasms (IPMNs). In this study we explored risk factors for subsequent PC in patients with MD-IPMN undergoing partial pancreatectomy.

Methods: We searched the Mayo Clinic surgical pathology database for all cases of resected MD-IPMN between 1997 and 2014.

Autoimmune Pancreatitis.

Over the course of the last 2 decades our knowledge of autoimmune pancreatitis has increased exponentially. In this review, we summarize the clinical presentation, diagnosis and treatment of AIP, to better allow general gastroenterologists and primary care providers to consider AIP as a as a rare but important cause of painless obstructive jaundice and recurrent acute pancreatitis. While steroids remain the mainstay of first line therapy, a number of patients with type 1 AIP require immunomodulators or rituximab to maintain remission; recommendations on the management of relapses continue to evolve.

Model to Determine Risk of Pancreatic Cancer in Patients With New-Onset Diabetes.

Background & Aims: Of patients with new-onset diabetes (NOD; based on glycemic status) older than 50 years, approximately 1% are diagnosed with pancreatic cancer (PC) within 3 years. We aimed to develop and validate a model to determine risk of PC in patients with NOD.

Methods: We retrospectively collected data from 4 independent and nonoverlapping cohorts of patients (N = 1,561) with NOD (based on glycemic status; data collected at date of diagnosis and 12 months previously) in the Rochester Epidemiology Project from January 1, 2000 through December 31, 2015 to create our model.

Comparison of Fasting Human Pancreatic Polypeptide Levels Among Patients With Pancreatic Ductal Adenocarcinoma, Chronic Pancreatitis, and Type 2 Diabetes Mellitus.

Objectives: Human pancreatic polypeptide (HPP) is a hormone secreted by the ventral pancreas. While postprandial HPP levels have been studied in chronic pancreatitis (CP) and pancreatic ductal adenocarcinoma (PDAC), there are limited data on fasting HPP in these diseases.

Methods: Fasting serum HPP was measured in the following groups of patients: CP with diabetes mellitus (DM) (n = 16), CP without DM (n = 34), PDAC with new-onset DM (n = 50), PDAC without DM (n = 49), new-onset type 2 DM (n = 50), and controls without DM (n = 49).

Portal Hypertension Complications Are Frequently the First Presentation of NAFLD in Patients Undergoing Liver Transplantation Evaluation.

Introduction: Nonalcoholic fatty liver disease (NAFLD) is likely to replace Hepatitis C as the leading cause of cirrhosis resulting in liver transplantation (LT) within a few years. Unfortunately, due to the lack of established guidelines for the screening of NAFLD in high-risk populations, many patients present with portal hypertension complications as their first manifestation of NAFLD require a LT evaluation. We aimed to investigate what proportion of patients who underwent LT for NAFLD-cirrhosis had knowledge of their liver disease prior to presenting with portal hypertension complications and to identify differences in clinical parameters between those with and without knowledge of preexisting NAFLD.

YouTube videos as a source of medical information during the Ebola hemorrhagic fever epidemic.

The content and quality of medical information available on video sharing websites such as YouTube is not known. We analyzed the source and quality of medical information about Ebola hemorrhagic fever (EHF) disseminated on YouTube and the video characteristics that influence viewer behavior. An inquiry for the search term 'Ebola' was made on YouTube.

Gastric Polyposis: A Rare Cause of Iron Deficiency Anemia in a Patient With Portal Hypertension.

Portal hypertension leading to gastric polyposis has rarely been reported. More common gastric manifestations of portal hypertension are portal hypertensive gastropathy and gastric antral vascular ectasia (GAVE). We report a case of a patient in whom portal hypertension manifested as bleeding gastric polyps leading to transfusion-dependent iron deficiency anemia.
