Endoscopic ultrasound fine-needle aspiration characteristics of primary adenocarcinoma versus other malignant neoplasms of the pancreas.

Background: Endoscopic ultrasound (EUS) with fine-needle aspiration (FNA) is often used to assist in the evaluation of pancreatic lesions and may help to diagnose benign versus malignant neoplasms. However, there is a paucity of literature regarding comparative EUS characteristics of various malignant pancreatic neoplasms (primary and metastatic).

Objective: To compare and characterize primary pancreatic adenocarcinoma versus other malignant neoplasms, hereafter referred to as nonprimary pancreatic adenocarcinoma (NPPA), diagnosed by EUS-guided FNA.

IBS patients' willingness to take risks with medications.

Objectives: We explored irritable bowel syndrome (IBS) patients' impulsivity and risk-taking behavior and their willingness to take medication risks.

Methods: A validated questionnaire assessed the illness experience of IBS patients. A standard gamble evaluated respondents' willingness to take medication risks.

Lactated Ringer's solution reduces systemic inflammation compared with saline in patients with acute pancreatitis.

Background & Aims: Aggressive fluid resuscitation is recommended for initial management of acute pancreatitis. We performed a randomized controlled trial to evaluate the impact of a goal-directed fluid resuscitation protocol on systemic inflammation in patients with acute pancreatitis. We then determined the impact of resuscitation with lactated Ringer's solution, compared with normal saline.
