OBJECTIVES Pancreatic cystic neoplasms (PCNs) are being detected with increased frequency. The aims of this study were to determine the incidence of malignancy and develop an imaging-based system for prediction of malignancy in PCN. METHODS We conducted a retrospective cohort study of patients ≥18 years of age with confirmed PCN from January 2005 to(More)
In mild-to-moderate inflammatory bowel disease, particularly ulcerative colitis, 5-aminosalicylic acid (5-ASA) remains a cornerstone of therapy. Sulfasalazine, originally synthesized in 1940 as an arthritis treatment for Sweden's King Gustaf V, is an azo-linked compound between 5-ASA and sulfapyridine.

OBJECTIVE The aim of this study was to determine how patient anxiety, knowledge, and cancer worry influence preferences for management of pancreatic cysts. METHODS We performed a prospective, cross-sectional study using a disease-specific survey instrument. We included patients older than 18 years who were diagnosed with a pancreatic cyst.

Background and study aims: Endoscopic retrograde cholangiopancreatography-related infections are of increasing global concern due to the emergence of multidrug-resistant bacteria such as carbapenem-resistant enterobacteriaceae (CRE), with bacterial biofilm production postulated as one cause of persistent infection from such virulent organisms. Because(More)
OBJECTIVES Pancreatic cystic neoplasms (PCNs) are being detected with increased frequency. Current clinical practice guidelines emphasize management based on cyst-related features. We aimed to evaluate the impact of comorbidity on mortality in PCN patients via competing risk analysis. METHODS We analyzed a retrospective cohort of patients diagnosed(More)
