BACKGROUND: Orthotopic liver transplantation (OLT) is considered the standard for children with hepatoblastoma (HB) in whom complete surgical resection is not possible. However, OLT is not always available or feasible. OBJECTIVE: To describe the outcome of children with HB who were initially deemed unresectable and underwent complex hepatectomy with planned close margins, and ultimately avoided OLT. METHODS: Demographic data, surgical and pathologic details, and survival information were collected from children treated for HB between January 2010 to December 2015...

We discuss the case of a rare and often unrecognized neurologic syndrome, called Acquired Hepatocerebral Degeneration (AHD), observed in patients with advanced liver disease and portosystemic shunts. The clinical manifestations can be very heterogeneous and in our case included a combination of cerebellar and extrapyramidal signs, arisen in a period of few days. Brain Magnetic Resonance Imaging (MRI) showed, in T1-weighted images, diffuse bilateral hyper intensities in basal ganglia and biemispheric brain and cerebellar cortices, resembling paramagnetic deposits...

BACKGROUND: Pretreatment of marginal organs by perfusion is a promising opportunity to consider more organs for transplantation. Protection of human DCD (donation after cardiac death) livers by a novel machine perfusion technique, hypothermic oxygenated perfusion (HOPE), was recently established. Here we tested in a rodent transplant model, whether HOPE is also useful for fatty liver grafts. METHODS: Rats were fed over 3 weeks with a special Methionine-Choline-Deficient-Diet (MCDD) to induce severe hepatic macrosteatosis (≥60%)...

BACKGROUND: Acute kidney injury (AKI) is a common and serious complication of orthotopic liver transplantation (OLT). Transfusion of older red blood cells (RBCs) has been implicated in poor outcomes in trauma, cardiac surgery, and critically ill patients. However, whether transfusion of older RBCs plays any role in post-OLT AKI remained unknown. The aim of this study was to investigate the effect of the age of transfused RBCs on post-OLT AKI. METHODS: The clinical data of consecutive adult patients who received donation after cardiac death and underwent OLT from December 2011 to December 2015 were analyzed...

Liver transplantation has emerged as a vital therapy for end-stage liver diseases. Acute -phase inflammation play an important role in liver graft injury.Recent studies have revealed that inflammasome are responsible for initiating inflammation in early stage of acute organ rejection in liver transplantation, however the underlying mechanism remains unclear. Here we explored to block inflammasome activation to see whether it can alleviate early inflammation reaction during rejection of allgrafts in a rat model and gain further insights into the mechanism of inhibiting inflammation in allografts...

Post-transcriptional gene regulation by microRNAs (miRNAs) is involved in memory formation. However, the roles of individual miRNAs in these processes remain largely unknown. In this study, we want to clarify the role of miR-181a in hippocampus-dependent memory formation. A transient increase in miR-181a expression was observed after conditioned fear conditioning (CFC) and object location task (OLT) training. Selective overexpression or inhibition of miR-181a in the dorsal hippocampus (DH) via the injection of a miR-181a agomir or antagomir enhanced or impaired the CFC- and OLT-dependent memory formation, respectively...

INTRODUCTION: Several biomarkers have been suggested as early predictors of acute kidney injury (AKI) after orthotopic liver transplantation (OLT). Neutrophil gelatinase-associated lipocalin-2 (NGAL) appears to be a promising predictor of AKI after OLT, but the clinical benefit remains to be proven. Recently, systemic macrophage migration inhibitory factor (MIF) has been proposed as early indicator for requirement of renal replacement therapy after OLT. The aim of this prospective, observational pilot study was to compare the predictive values of serum and urinary MIF for severe AKI after OLT to those of serum and urinary NGAL...

PURPOSE: To quantify arthroscopic accessibility of the talar dome with predefined ankle positions through anterior and posterior approaches. METHODS: Fourteen below-knee cadaver specimens underwent preoperative range of motion assessments. A 30° 2.7-mm arthroscopic camera was used to mark accessible areas at varying ankle positions. Accessible regions were quantified using a surface laser scanner and digital 3 × 3 grid. Statistical analyses were performed to detect differences in arthroscopic accessibility between different flexion angles and noninvasive distraction...

Curcumin is a natural polyphenol with evidence of antioxidant, anti-inflammatory and neuroprotective properties. Recent evidence also suggests that curcumin increases cognitive performance in animal models of dementia, and this effect would be related to its capacity to enhance adult neurogenesis. The aim of this study was to test the hypothesis that curcumin treatment would be able to preserve cognition by increasing neurogenesis and decreasing neuroinflammation in the model of dementia of Alzheimer's type induced by an intracerebroventricular injection of streptozotocin (ICV-STZ) in Wistar rats...

BACKGROUND: Sclerosing peritonitis (SP) is a rare but potentially fatal complication following orthotopic liver transplantation (OLT). The definitive surgical management is via a laparotomy peritonectomy and enterolysis procedure, but this carries risks particularly in the immunosuppressed transplant patient population. The natural history of SP is known from a handful of case reports and series, which mostly report de novo cases arising early on following OLT. The aim of this study was to identify all cases of de novo SP following OLT and the outcomes of management...

INTRODUCTION: Obesity is frequently encountered in patients with orthotopic liver transplant (OLT). The role of bariatric surgery is still unclear for this specific population. The aim of this study was to review our experience with laparoscopic sleeve gastrectomy (LSG) after OLT. MATERIAL AND METHODS: We performed a retrospective case-control study of patients undergoing LSG after OLT from 2010 to 2016. OLT-LSG patients were matched by age, sex, body mass index (BMI), and year to non-OLT patients undergoing LSG...

INTRODUCTION: Almost all pediatric orthotopic liver transplant (OLT) recipients require mechanical ventilation in the early postoperative period. Prolonged postoperative mechanical ventilation (PPMV) may be a marker of severe disease and may be associated with morbidity and mortality. We determined the incidence and risk factors for PPMV in children who underwent OLT. METHODS: This was a retrospective analysis of data collected on 128 pediatric OLT recipients. PPMV was defined as postoperative ventilation ≥ 4 days...

BACKGROUND AND AIMS: Biliary strictures after orthotopic liver transplantation (OLT) are typically managed by sequential ERCP procedures, with incremental dilation of the stricture and stent exchange (IDSE) and placement of new stents. This approach resolves >80% of strictures after 12 months but requires costly, lengthy ERCPs with significant patient radiation exposure. Increasing awareness of the harmful effects of radiation, escalating healthcare costs, and decreasing reimbursement for procedures mandate maximal efficiency in performing ERCP...

Orthotopic liver transplantation (OLT) represents a curative treatment option for end-stage liver disease (ESLD). While epidemiology of ESLD has recently changed due the rising prevalence of non-alcoholic fatty liver disease (NAFLD) and decreased burden of hepatitis C virus (HCV) infections due to highly-effective antiviral regimens, the management of portal hypertension (PHT) remains a clinical challenge in the pre- and post-OLT setting. The measurement of hepatic venous pressure gradient (HVPG) represents the most reliable, but invasive tool for assessment of the severity of PHT...
