Synchronous Periampullary Tumors in a Patient With Pancreas Divisum and Neurofibromatosis Type 1.

Introduction: In this study, we describe for the first time a Neurofibromatosis type 1 patient with pancreas divisum, multiple periampullary tumors and germline pathogenic variants in and genes.

Case Report: A 62-year-old female NF1 patient presented with weakness, choluria, nausea, and diffuse abdominal pain to an emergency room service. Magnetic resonance imaging revealed an abdominal mass involving the periampullary region and pancreas divisum.

THE ROLE OF IMMUNOINFLAMMATORY MARKERS IN THE PROGNOSIS AND RESECTABILITY OF PANCREATIC ADENOCARCINOMA.

Background: Pancreatic adenocarcinoma has a high mortality rate. A prognostic tool is essential for a better risk stratification. The neutrophil/lymphocyte ratio and adaptations and the platelet/lymphocyte ratio seem promising for this purpose.

Perioperative synbiotics decrease postoperative complications in periampullary neoplasms: a randomized, double-blind clinical trial.

Periampullary neoplasms are rapidly progressive tumors with a poor prognosis and high morbidity and mortality rates, which have a negative influence on patient outcomes. Some probiotics and prebiotics have the ability to protect the intestinal barrier and prevent bacterial translocation, infection, and postoperative complications. We evaluated the use of synbiotics in a prospective, double-blind study of patients undergoing surgery for periampullary neoplasms (PNs) and assessed the effect of these agents on nutritional status, postoperative complications, antibiotic use, length of hospital stay, and mortality.

Digital karyometry in pancreatic adenocarcinoma.

Objective: To characterize nuclei from pancreatic adenocarcinoma and nonneoplastic pancreatic tissue by digital karyometry, demonstrating specific nuclear signatures for each of them.

Study Design: Of cells from malignant and nonmalignant pancreatic tissue, 1,300 nuclei were assessed by digital karyometry from paraffin blocks stored at the Pathology Service of Hospital de Clinicas de Porto Alegre. A set of 40 features descriptive of the spatial and statistical distribution of nuclear chromatin was computed for each nucleus.
