Autoimmune pancreatitis(AIP) is a distinct form of chronic pancreatitis that is increasingly being reported. The presentation and clinical image findings of AIP sometimes resemble those of several pancreatic malignancies, but the therapeutic strategy differs appreciably. Therefore, accurate diagnosis is necessary for cases of AIP. To date, AIP is classified into two distinct subtypes from the viewpoints of etiology, serum markers, histology, other organ involvements, and frequency of relapse: type 1 is related to Ig G4(lymphoplasmacytic sclerosing pancreatitis) and type 2 is related to a granulocytic epithelial lesion(idiopathic duct-centric chronic pancreatitis). Both types of AIP are characterized by focal or diffuse pancreatic enlargement accompanied with a narrowing of the main pancreatic duct, and both show dramatic responses to corticosteroid. Unlike type 2, type 1 is characteristically associated with increasing levels of serum Ig G4 and positive serum autoantibodies, abundant infiltration of Ig G4-positive plasmacytes, frequent extrapancreatic lesions, and relapse. These findings have led several countries to propose diagnostic criteria for AIP, which consist of essentially similar diagnostic items; however, several differences exist for each country, mainly due to differences in the definition of AIP and the modalities used to diagnose this disease. An attempt to unite the diagnostic criteria worldwide was made with the publication in 2011 of the international consensus diagnostic criteria for AIP, established at the 2010 Congress of the International Association of Pancreatology(IAP).

AIM: To investigate the accuracy of endoscopic or biopsy diagnoses of superficial nonampullary duodenal epithelial tumors(NADETs).METHODS:Clinicopathological data were reviewed for84 superficial NADETs from 74 patients who underwent surgery or endoscopic resection between September2002 and August 2014 at a single prefectural cancer *** NADETs were defined as lesions confined to the mucosa or *** and clinicopathological data were retrieved from charts,endoscopic and pathologic *** reports included endoscopic diagnosis,location,gross type,diameter,color,and presence or absence of *** diagnoses were made by an endoscopist in charge of the examination before biopsy specimens were *** images were obtained using routine,front-view,high-resolution video endoscopy,and chromoendoscopy with indigocarmine was performed for all *** images were reviewed by at least two endoscopists to assess endoscopic findings indicative of *** diagnoses based on endoscopy and biopsy findings were compared with histological diagnoses of resected ***,specificity,and accuracy were assessed for endoscopic diagnosis and biopsy ***:The majority(81%)of the lesions were located in the second portion of the *** median lesion diameter was 14.5 mm according to final *** was performed for 49 lesions from 39 patients,and 35 lesions from 35 patients were endoscopically *** histology confirmed 65carcinomas,15 adenomas,and 3 hyperplasias.A finaldiagnosis of duodenal carcinoma was made for 91%(52/57)of the lesions diagnosed as carcinoma by endoscopy and 93%(42/45)of the lesions diagnosed as carcinoma by *** sensitivity,specificity,and accuracy of endoscopic diagnoses were 80%,72%,and 78%,respectively,whereas those of biopsy diagnoses were 72%,80%,and 74%,*** diagnoses of carcinomas were made in88%(57/65)of

On April 26-27, 2013, the Step by Step Foundation hosted the Second International Spinal Cord Repair Meeting at the Fira Barcelona Convention Center in Hospitalet de Llobregat, Spain, highlighting some of the exciting research including clinical trials which show promise for treatments for this devastating disorder. This meeting brought together clinicians, clinical scientists and molecular biologists from more than 10 countries to evaluate current knowledge on clinical, cellular, and biomolecular aspects of spinal cord injury. A major goal of the conference in advancing the translation of research data to the clinic was to promote multi-pronged approaches for therapy of this complex problem.
