Are the causes similar for benign and severe forms of acute pancreatitis?
Non-alcoholic and non-biliary causes are less frequent in necrotizing pancreatitis (Balthazar>or =D). For the other severity scores, the distribution of causes was similar. After exclusion of biliary and alcoholic causes, a careful search for other etiologies should be carried out in both benign and severe cases of acute pancreatitis.
MR-PWI abnormalities are seen in two thirds of lacunar infarcts, and are associated with stroke rather than TIA. Normal PWI identifies patients at low risk of early clinical deterioration.
