Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR and SPINK1 variants were associated with pancreatitis risk. We now report two associations at genome-wide significance identified and(More)
CFTR is a dynamically regulated anion channel. Intracellular WNK1-SPAK activation causes CFTR to change permeability and conductance characteristics from a chloride-preferring to bicarbonate-preferring channel through unknown mechanisms. Two severe CFTR mutations (CFTRsev) cause complete loss of CFTR function and result in cystic fibrosis (CF), a severe(More)
CONTEXT Segmental arterial mediolysis is an uncommon, non-atherosclerotic, non-inflammatory arteriopathy that involves areas of dissecting aneurysms and strictures that are caused by outer media lysis of the arterial wall from areas of medial necrosis of uncertain pathogenesis. It has a predilection for splanchnic arteries and often presents as abdominal(More)
We present a rare case of gastrointestinal (GI) bleeding associated with metastatic prostate adenocarcinoma to the stomach. Prostate cancer, which is the most common noncutaneous malignancy among men, rarely spreads to the stomach, with only 7 cases reported in the English literature. Symptoms may include abdominal pain, nausea, vomiting, and GI bleeding.(More)
Autoimmune pancreatitis is a form of chronic pancreatitis that was first described by Sarles et al. in 1961, and later coined in 1995 by Yoshida et al. [1, 2]. Subsequently, two types of autoimmune pancreatitis have been described. Autoimmune pancreatitis type 1 fits the classic description of the disease and is associated with a lymphoplasmacytic(More)
