BACKGROUND: Surgical site infections (SSI) remain a major source of morbidity and cost after resection of intra-abdominal malignancies. Negative pressure wound therapy (NPWT) has been reported to significantly reduce SSI when applied to the closed laparotomy incision. This paper reports results of a randomized clinical trial examining the effect of NPWT on SSI rates in surgical oncology patients with increased risk for infectious complications. STUDY DESIGN: From 2012-2016, 265 patients underwent open resection of intra-abdominal neoplasms stratified into three groups: gastrointestinal (n=57), pancreas (n=73), and peritoneal surface malignancy (n=135)...

BACKGROUND: LPD has been cautiously regarded as feasible and safe for resection and reconstruction. However, anastomosis of the remnant pancreas is still thought to be a critical obstacle to the dissemination of LPD in general practice. This study presents a new technique of pancreaticojejunostomy for nondilated pancreatic duct and evaluates its safety and reliability. METHODS: From July 2014 to June 2015, a total of 52 patients underwent LPD with the new technique...

Hepatitis C virus (HCV) infection has also been associated with many extrahepatic manifestations including the development of B-cell non-Hodgkin's lymphoma (NHL). Primary pancreatic lymphoma is very rare and comprises 2.2% of NHL and 4.9% of all pancreatic malignancies. Our patient was a woman with a history of infection with HCV found to have a mass in the head of the pancreas. Biopsy of the mass revealed a high-grade B-cell lymphoma consistent with Burkitt's lymphoma. Our case reflects a need to initiate antiviral therapy for all patients infected with HCV even in early stages of fibrosis to prevent cirrhosis and other extrahepatic manifestations of infection with HCV...

Retroperitoneal fibrosis (RPF) is a rare disease characterised by fibrous tissue proliferation in the retroperitoneum, with encasement of the ureters and large vessels of the abdomen as the most destructive of potentially severe complications. It can either be idiopathic, or secondary to infections, malignancies, or the use of certain drugs. The idiopathic form accounts for approximately 75% of the cases, and is usually responsive to immunosuppressive therapy. In recent years, the emergence of a new clinical entity, IgG4-related disease (IgG4-RD), shed light on many fibro-inflammatory disorders once thought to be separate clinical entities, although frequently associated in the so-called multifocal fibrosclerosis...

Ribosomopathies are a family of inherited disorders caused by mutations in genes necessary for ribosomal function. Shwachman-Diamond Bodian Syndrome (SDS) is an autosomal recessive disease caused, in most patients, by mutations of the SBDS gene. SBDS is a protein required for the maturation of 60S ribosomes. SDS patients present exocrine pancreatic insufficiency, neutropenia, chronic infections, and skeletal abnormalities. Later in life, patients are prone to myelodisplastic syndrome and acute myeloid leukemia (AML)...

BACKGROUND: Obstructive jaundice is a common presenting symptom among patients with pancreatic cancer. While benefits of preoperative biliary drainage have been suggested by previous studies, recent evidence has shown no significant improvements of preoperative biliary drainage on the postoperative outcome but rather an increase of complications. There is no clear consensus on whether to treat malignant obstructive jaundice with preoperative biliary drainage prior to operative intervention or to proceed directly to resection...

The association between H. pylori infection and pancreatic cancer risk remains controversial. We conducted a nested case-control study with 448 pancreatic cancer cases and their individually matched control subjects, based on the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, to determine whether there was an altered pancreatic cancer risk associated with H. pylori infection and chronic corpus atrophic gastritis. Conditional logistic regression models were applied to calculate odds ratios (ORs) and corresponding 95% confidence intervals (CIs), adjusted for matching factors and other potential confounders...

The effect of IPNV-VHSV coinfection and superinfection on the mortality caused by both viruses in Senegalese sole has been analysed. No effect was observed after coinfection. However, a clear viral interference was recorded between a primary IPNV and a subsequent VHSV infection, which led to a survival increase in the infected sole of 50% points when compared with fish infected only with VHSV. The significantly higher Mx transcriptional values in the fish pre-exposed to IPNV (at least at first days after superinfection) and the increased daily mortality when low Mx transcriptional levels were recorded suggest that Mx may be involved in the protective effect against VHSV infection...

Infectious pancreatic necrosis virus (IPNV) is an important virus which affects the salmonid aquaculture industry worldwide; therefore, it is important to develop rapid and reliable methods of diagnosis to detect the disease at early stages. Nowadays, RT-qPCR is replacing other methods because it provides additional information on the viral load, which is important to have a better understanding of the virus replication level and of the stage of the infection and its risk level. The main problem stems from the high diversity of this virus, which can compromise the reliability of the diagnosis...

The parasite Trypanosoma cruzi causes a persistent infection, Chagas disease, affecting millions of persons in endemic areas of Latin America. As a result of immigration, this disease has now been diagnosed in non-endemic areas worldwide. Although, the heart and gastrointestinal tract are the most studied, the insulin-secreting β cell of the endocrine pancreas is also a target of infection. In this review, we summarize available clinical and laboratory evidence to determine whether T. cruzi-infection-mediated changes of β cell function is likely to contribute to the development of hyperglycemia and diabetes...

Pancreatic fluid collections (PFCs) are a frequent complication of pancreatitis, or less commonly, pancreatic trauma or surgery. The revised Atlanta Classification categorizes PFCs as acute or chronic, with further subclassification of acute collections into acute peripancreatic collections and acute necrotic collections and of chronic fluid collections into pseudocysts and walled-off pancreatic necrosis. Acute PFCs are generally only subjected to an intervention when they are infected and not responding to antibiotics and are not managed endoscopically...

INTRODUCTION: Cystic fibrosis is a chronic disease with multiple organ involvement and chiefly results in chronic respiratory infections, pancreatic insufficiency and associated complications. The age at diagnosis, clinical presentation, rate of disease progression and prognosis is variable among patients. This study is designed to evaluate the behavior of disease to provide epidemiologic data for early recognition and proper management. MATERIAL AND METHODS: The study was designed as an active surveillance of 192 patients diagnosed with cystic fibrosis in a tertiary lung disease centre between 2008 and 2015...

Viral hemorrhagic septicemia virus (VHSV) and infectious pancreatic necrosis virus (IPNV) are economically important pathogens of the salmonid aquaculture industry. In previous work we demonstrated that a cell line persistently infected with IPNV (EPC(IPNV)) exhibited antiviral activity against superinfection with the heterologous virus VHSV. This work extends our study by analyzing the replication of VHSV in the IPNV-persistently infected cells. At early and late stages of infection VHSV RNA synthesis, as well as VHSV-induced syncytia formation, were examined in EPC(IPNV) cultures...

The IFIH1 gene encodes the pattern recognition receptor MDA5. A common polymorphism in IFIH1 (rs1990760, A946T) confers increased risk for autoimmune disease, including type 1-diabetes (T1D). Coxsackievirus infections are linked to T1D and cause beta-cell damage in vitro. Here we demonstrate that the rs1990760 polymorphism regulates the interferon (IFN) signature expressed by human pancreatic islets following Coxsackievirus infection. A strong IFN signature was associated with high expression of IFNλ1 and IFNλ2, linking rs1990760 to the expression of type III IFNs...

The pathogenesis of human type 1 diabetes, characterized by immune-mediated damage of insulin-producing β-cells of pancreatic islets, may involve viral infection. Essential components of the innate immune antiviral response, including type I interferon (IFN) and IFN receptor-mediated signaling pathways, are candidates for determining susceptibility to human type 1 diabetes. Numerous aspects of human type 1 diabetes pathogenesis are recapitulated in the LEW.1WR1 rat model. Diabetes can be induced in LEW.1WR1 weanling rats challenged with virus or with the viral mimetic polyinosinic:polycytidylic acid (poly I:C)...

β-Lactam antibiotics have been used for many years to treat bacterial infections. However the effective treatment of an increasing range of microbial infections is threatened by bacterial resistance to β-lactams: the prolonged, widespread and at times reckless use of these drugs has spawned widespread resistance, which renders them ineffective against many bacterial strains. The cyclobutanone ring system is isosteric with β-lactam: in cyclobutanone analogues, the eponymous cyclic amide is replaced with an all-carbon ring, the amide N substituted by a tertiary C-H α to a ketone...

Effective adoptive immunotherapy has proved elusive for many types of human cancer, often due to difficulties achieving robust expansion of natural tumor-specific T-cells from peripheral blood. We hypothesized that antigen-driven T-cell expansion might best be triggered in vitro by acute activation of innate immunity to mimic a life-threatening infection. Unfractionated peripheral blood mononuclear cells (PBMC) were subjected to a two-step culture, first synchronizing their exposure to exogenous antigens with aggressive surrogate activation of innate immunity, followed by γ-chain cytokine-modulated T-cell hyperexpansion...
