OBJECTIVE: The aim of this study is to predict the risk of acute pancreatitis (AP)-induced portal vein thrombosis(PVT) by radical basis function (RBF) artificial neural networks (ANNs) model. METHODS: A retrospective or consecutive study of 426 individuals with AP at our unit between January 1(st) 2011 to July 31(st) 2016 was conducted. All individuals were subjected to RBF ANNs. Variables included age, gender, red blood cell specific volume (Hct), prothrombin time (PT), fasting blood glucose (FBG), D-Dimer, concentration of serum calcium ([Ca(2+)]), triglyceride (TG), serum amylase (AMY), acute physiology and chronic health evaluation II (APACHEII) score, and Ranson score...

The pathological presence of tissue factor (TF) in cancer cells promotes tumor-initiated thrombosis and cancer metastasis. We found that TF is aberrantly present in large percentage of aggressive triple negative breast cancer (TNBC) and pancreatic adenocarcinoma (PaC), two most lethal forms of malignancy that urgently need effective treatment. TF expression in TNBC clustered with higher levels of vimentin, basal-type keratins KRT5/14 and caveolin-1 but lower levels of luminal-type biomarkers. We developed a novel and specific anti-TF therapeutic antibody SC1, which displayed an exceedingly high potency against TF extracellular domain (EC50: 0...

Portal vein thrombosis (PVT) is a rare but serious postoperative complication associated with irreversible electroporation (IRE). We report a case of postoperative PVT in a 54-year-old woman who underwent IRE for locally advanced pancreatic cancer. Drain removal and discharge of the patient from the hospital were scheduled on postoperative day (POD) 7; however, a magnetic resonance imaging scan revealed the presence of PVT. We suspected postoperative inflammation in the pancreas as the main cause of PVT. However, the patient did not undergo any medical treatment because she did not have any clinical symptoms, and she was discharged on POD 8...

An innovative technique for pancreas transplantation is described. The main aspect consists of the horizontal positioning of the pancreas, which allows a better venous outflow, thus preventing thrombosis and graft loss. The program of pancreas transplantation in this national reference center for pancreatic and liver surgery was started in 2007; the initial results were considered poor, resulting in the loss of half of the grafts due to venous thrombosis. After analyzing the possible causes, this technique was proposed and successfully implemented, reducing the postoperative complications, particularly the problem of venous thrombosis...

Circulating microvesicles (MVs) are suggested to be important contributors to cancer-associated thrombosis due to the presence of surface-bound procoagulant molecules like tissue factor (TF) and phosphatidylserine (PS). Pancreatic cancer is considered to be one of the most prothrombotic malignancies. The aim of this study was to describe the impact of analytical variables on MV-associated thrombin generation in patients with pancreatic cancer and in healthy controls. MVs were isolated from citrated plasma and added to pooled normal plasma (PNP)...

OBJECTIVE: The pathophysiology of primary-stage hepatic metastases from gastrointestinal cancers may provide clues to their formation. We investigated initial features of hepatic metastases from pancreatic cancer by examining the histologies of radiographically occult hepatic micrometastases. METHODS: We examined 133 consecutive pancreatic cancer patients with no evident hepatic metastases on preoperative imaging. An indocyanine green near-infrared camera system was used to detect hepatic metastases during surgery; preoperatively acquired images of patients were then retrospectively reviewed...

Chronic pancreatitis is defined as a pathological fibro-inflammatory syndrome of the pancreas in individuals with genetic, environmental and/or other risk factors who develop persistent pathological responses to parenchymal injury or stress. Potential causes can include toxic factors (such as alcohol or smoking), metabolic abnormalities, idiopathic mechanisms, genetics, autoimmune responses and obstructive mechanisms. The pathophysiology of chronic pancreatitis is fairly complex and includes acinar cell injury, acinar stress responses, duct dysfunction, persistent or altered inflammation, and/or neuro-immune crosstalk, but these mechanisms are not completely understood...

Riluzole is the only drug approved for the treatment of patients with Amyotrophic Lateral Sclerosis (ALS). It is well tolerated, being the most frequent adverse effects asthenia, nausea and reversible increase of liver enzymes levels. Severe adverse effects are extremely rare. We report for the first time, two patients with sporadic limb-onset ALS who developed recurrent acute pancreatitis (AP), with portal vein thrombosis as complication, during treatment with riluzole. We suggest that AP should be considered asa probable rare and severe side effect of treatment with riluzole in patients with ALS...

BACKGROUND: Pancreatic cancer patients have a high rate of venous thromboembolism. Human pancreatic tumors and cell lines express high levels of tissue factor (TF) and release TF-positive microvesicles (TF+MVs). In pancreatic cancer patients, tumor-derived TF+MVs are present in blood and increased levels are associated with venous thromboembolism and decreased survival. Previous studies have shown that mice with orthotopic human or murine pancreatic tumors have circulating tumor-derived TF+MVs, an activated clotting system, and larger clots than controls in an inferior vena cava stenosis model...

Adults with acute lymphoblastic leukemia (ALL) do worse than children. From 7/2008 to 12/2014, Nordic and Baltic centers treated 1509 consecutive patients 1-45 years with Philadelphia chromosome-negative ALL according to the NOPHO ALL2008 without cranial irradiation. 1022 patients were 1-9 years (A), 266 were 10-17 years (B), and 221 were 18-45 years (C). Sixteen patients (three adults) died during induction. All others achieved remission after induction or 1-3 intensive blocks. Subsequently, 45 patients (12 adults) died, 122 patients relapsed (32 adults) with a median time to relapse of 1...

Cancer patients have an increased risk of venous thromboembolism (VTE). In this review, we will summarize common and cancer type-specific pathways of VTE in cancer patients. Increased levels of leukocytes, platelets and tissue factor-positive (TF+) microvesicles are all potential factors that alone or in combination increase cancer-associated thrombosis. Lung and colorectal cancer patients often exhibit leukocytosis. Neutrophils could increase VTE in cancer patients by releasing neutrophil extracellular traps whereas monocytes may express TF...

Pancreatic allograft thrombosis (PAT) remains the leading cause of nonimmunologic graft failure. Here, we propose a new computed tomography (CT) grading system of PAT to identify risk factors for allograft loss and outline a management algorithm by retrospective review of consecutive pancreatic transplantations between 2009 and 2014. Triple-phase CT scans were graded independently by 2 radiologists as grade 0, no thrombosis; grade 1, peripheral thrombosis; grade 2, intermediate non-occlusive thrombosis; and grade 3, central occlusive thrombosis...

Until recently, pancreas transplantation has mostly been performed with exocrine drainage via duodenojejunostomy (DJ). Since 2012, DJ was substituted with duodenoduodenostomy (DD) in our hospital, allowing endoscopic access for biopsies. This study assessed safety profiles with DD versus DJ procedures and clinical outcomes with the DD technique in pancreas transplantation. DD patients (n = 117; 62 simultaneous pancreas-kidney [SPKDD ] and 55 pancreas transplantation alone [PTADD ] with median follow-up 2...

Splenic infarction is rare and occurs when the splenic artery or its branches become occluded, either by an embolus or by in situ thrombosis. In situ thrombosis of splenic artery leading to splenic and pancreatic abscess formation after infarction is rare. We here present a case of a 65-year-old man who was found to have acute complete splenic and distal pancreatic infarction and abscess formation attributable to in situ thrombosis of splenic artery.

While abutment, encasement or vessel occlusion are identified in most patients with a pancreatic tumor, tumor thrombosis is an uncommon finding. In particular, there are no description in the literature of tumor thrombosis associated with ductal adenocarcinoma, the most common pancreatic tumor. On the other hand, surgical series reveal that tumor thrombosis is associated with about 5% of pancreatic neuroendocrine neoplasms (PanNENs), and literature data suggest that this finding is frequently underreported on pre-operative imaging examinations...
