INTRODUCTION: Acute pancreatitis (AP) is one of the most common diseases involving necrotic inflammation. Bone marrow mesenchymal stem cells (BMMSCs) have the potential of multi-directional differentiation and self-renewal for tissue repair. It remains less clear if granulocyte colony-stimulating factor (G-CSF) can improve the therapeutic effect of BMMSC transplant in AP. Therefore, we explored this issue in a rat model of experimental AP. RESULTS: Transplanted PKH26-positive BMMSCs were present in the injured pancreatic tissue, with some cells co-expressed pancreatic cellular markers, including Pax-4, Ngn3 and Nkx-6...

BACKGROUND: Step-up approach consisting of multiple minimally invasive techniques has gradually become the mainstream for managing infected pancreatic necrosis (IPN). In the present study, we aimed to compare the safety and efficacy of a novel four-step approach and the conventional approach in managing IPN. METHODS: According to the treatment strategy, consecutive patients fulfilling the inclusion criteria were put into two time intervals to conduct a before-and-after comparison: the conventional group (2010-2011) and the novel four-step group (2012-2013)...

Raoultella planticola (R. planticola), considered an environmental organism, is a gram negative, motile, bacillus with phenotypic similarities to the genus Klebsiella. The organism remains a rare cause of human infection with a few cases reported in the literature. However, since its description in 1981 there have been increasing rates of infections caused by R. planticola with reports of conjunctivitis, liver abscess, cholangitis, pancreatitis, and necrotizing fasciitis. More concerning are reports of carbapenemase-producing isolates which have led to the only 2 mortalities associated with R...

BACKGROUND: Surgeons, in general, underestimate the replaced left hepatic artery (rLHA) that arises from the left gastric artery (LGA), compared with the replaced right hepatic artery (rRHA), especially in standard gastric cancer surgery. During pancreaticoduodenectomy (PD), preservation of the rRHA arising from the superior mesenteric artery (SMA) is widely accepted to prevent critical postoperative complications, such as liver necrosis, bile duct ischemia, and biliary anastomotic leakage...

BACKGROUND: A disconnected distal pancreas (DDP) remnant is a morbid sequela of necrotizing pancreatitis. Definitive surgical management can be accomplished by either fistulojejunostomy (FJ) or distal pancreatectomy (DP). It is unclear which operative approach is superior with regard to short- and long-term outcomes. METHODS: Between 2002 and 2014, patients undergoing either FJ or DP for DDP were retrospectively identified at a center specializing in pancreatic diseases...

Pigeon paramyxovirus serotype 1 (PPMV-1) is a globally distributed, virulent member of the avian paramyxovirus serotype 1 serogroup that causes mortality in columbiformes and poultry. Following introduction into the United States in the mid-1980s, PPMV-1 rapidly spread causing numerous mortality events in Eurasian collared-doves ( Streptopelia decaocto) (ECDOs) and rock pigeons ( Columba livia) (ROPIs). The investigators reviewed pathological findings of 70 naturally infected, free-ranging columbiforms from 25 different mortality events in the United States...

Acute pancreatitis (AP) is a common acute abdominal disease, 10-20% of which can evolve into severe AP (SAP) causing significant morbidity and mortality. Bone marrow-derived mesenchymal stem cells (BMSCs) have the potential of repairing SAP, but the detailed mechanism remains unknown. We demonstrate here that microRNA-9 (miR-9) modified BMSCs (pri-miR-9-BMSCs) can significantly reduce the pancreatic edema, infiltration, hemorrhage, necrosis, the release of amylase and lipase. Meanwhile, decreased local/systemic inflammatory response (TNF-α↓, IL-1β↓, IL-6↓, HMGB1↓, MPO↓, CD68↓, IL-4↑, IL-10↑, and TGF-β↑) and enhanced regeneration of damaged pancreas (Reg4↑, PTF1↑, and PDX1↑) are also promoted...

OBJECTIVES: Management of hepatic arterial complications after liver transplant remains challenging. The aim of our study was to assess the efficacy of rescue arterial revascularization using cryopreserved iliac artery allografts in this setting. MATERIALS AND METHODS: Medical records of patients with liver transplants who underwent rescue arterial revascularization using cryopreserved iliac artery allografts at a single institution were reviewed. RESULTS: From 1992 to 2015, 7 patients underwent rescue arterial revascularization using cryopreserved iliac artery allografts for hepatic artery pseudoaneurysm (3 patients), thrombosis (2 patients), aneurysm (1 patient), or stenosis (1 patient)...

BACKGROUND: Currently, both the step-up approach, combining percutaneous drainage (PD) and video-assisted retroperitoneal debridement (VARD), and endoscopic transgastric necrosectomy (ETN) are mini-invasive techniques for infected necrosis in severe acute pancreatitis. A combination of these approaches could maximize the management of necrotizing pancreatitis, conjugating the benefits from both the experiences. However, reporting of this combined strategy is anecdotal. This is the first reported case of severe necrotizing pancreatitis complicated by biliary fistula treated by a combination of ETN, PD, VARD, and endoscopic biliary stenting...

BACKGROUND: Identification of patients with necrotizing pancreatitis at high risk for a complicated course could facilitate clinical decision-making. In multiple diseases, several parameters of body composition are associated with impaired outcome, but studies in necrotizing pancreatitis are lacking. METHODS: A post hoc analysis was performed in a national prospective cohort of 639 patients with necrotizing pancreatitis. Skeletal muscle mass, skeletal muscle density, and visceral adipose tissue were measured at the third lumbar vertebra level (L3) on contrast-enhanced computed tomography (CT) within 10 days after initial admission and 1 month thereafter...

A 10-year-old child presented with prolonged fever, lymphadenopathy, weight loss, oral ulcers, alopecia and parotitis. She later developed arterial thrombosis, poly-serositis, nephritis, myocarditis, sacro-ilitis, autoimmune hemolytic anemia and refractory thrombocytopenia. Though anti-dsDNA was negative, she was diagnosed to have systemic lupus erythematosus (SLE). Terminally, she had pulmonary symptoms and succumbed to her illness. The autopsy showed lupus nephritis-Class II, polyserositis, myocarditis, inflammatory myositis, immune mediated vasculitis involving renal, coronary, pancreatic, adrenal, dermal and intramuscular arteries, and pulmonary hemorrhages and edema...

OBJECTIVE: We aimed to assess the effects of diazoxide on the mortality, pancreatic injury, and inflammatory response in an experimental model of acute pancreatitis. METHODS: Male Wistar rats (200-400 g) were divided randomly into two groups. Fifteen minutes before surgery, animals received physiological (0.9%) saline (3 mL/kg) (control group) or 45 mg/kg diazoxide (treatment group) via the intravenous route. Acute pancreatitis was induced by injection of 2.5% sodium taurocholate via the biliopancreatic duct...

Hydatid acute pancreatitis is a rare condition and always presents as consequence of acute edematous pancreatitis. Intrabiliary rupture of hepatic hydatid cysts and obstruction of papillary orifice with hydatid membrane is possible mechanism. A 49-year-old man was admitted with epigastric and right upper quadrant pain, nausea, and vomiting. Computed tomography scan showed 5 x 5 cm cyst in left hepatic lobe, which had ruptured into the biliary tract and caused necrotizing pancreatitis. Endoscopic retrograde cholangiopancreatography trial failed...

INTRODUCTION: In necrotizing acute pancreatitis (NAP), systemic inflammatory response syndrome (SIRS) and the compensatory anti-inflammatory response syndrome (CARS) decide overall outcome and mortality. In patients, low lymphocyte counts were found, but T-helper cells seemed to conversely increase. Our aim was to further categorize T-helper cells within the context of NAP induced SIRS and CARS. METHODS: NAP was induced by injection of sodium-taurocholate into the common bile duct of male BALB/c mice; sham treated animals received saline infusion...

BH3 mimetics are small-molecule inhibitors of B-cell lymphoma-2 (Bcl-2) and Bcl-xL, which disrupt the heterodimerisation of anti- and pro-apoptotic Bcl-2 family members sensitising cells to apoptotic death. These compounds have been developed as anti-cancer agents to counteract increased levels of Bcl-2 proteins often present in cancer cells. Application of a chemotherapeutic drug supported with a BH3 mimetic has the potential to overcome drug resistance in cancers overexpressing anti-apoptotic Bcl-2 proteins and thus increase the success rate of the treatment...
