HCC influence on patient survival after liver transplantation for HDV cirrhosis.

Background/aims: The effect of hepatocellular cancer (HCC) in patients transplanted for hepatitis B and D virus (HB/DV) cirrhosis is not well studied. Our aim was to study the long-term survival outcomes of patients who underwent liver transplantation for HB/DV cirrhosis with and without HCC.

Methodology: A total of 231 primary, adult, single- organ liver transplants were performed from 1990 to 2007.

Successful, combined long-term treatment of cerebral aspergillosis in a liver transplant patient.

Invasive aspergillosis has long been recognized as one of the most significant and often fatal opportunistic fungal infections in liver transplant recipients. We report a case of a liver transplant recipient who developed an Aspergillus fumigatus brain abscess that produced significant neurologic symptoms. The patient was managed successfully with a combination of surgery and medical treatment with Voriconazole.

Liver transplantation in Greek children: 15 years experience.

Liver transplantation (LT) is the only available live-saving procedure for children with irreversible liver failure. This paper reports our experience from the follow-up of 16 Greek children with end-stage liver failure who underwent a LT. Over a period of 15 years, 16 pediatric liver recipients received follow up after being subjected to OLT (orthotopic liver transplantation) due to end-stage liver failure.

Attenuation of liver ischemia/reperfusion induced apoptosis by epigallocatechin-3-gallate via down-regulation of NF-kappaB and c-Jun expression.

Introduction: Hepatic ischemia/reperfusion (I/R) activates Kupffer cells and initiates severe oxidative stress with enhanced production of reactive oxygen species (ROS) and tumor necrosis factor-alpha (TNF-alpha). ROS and TNF-alpha mediate the expression of nuclear factors and kinases, activating the signal transduction pathway, and triggering apoptosis. The aim of our study was to evaluate the potential protective effect of (-)-epigallocatechin-3-gallate (EGCG) administration in inhibition of apoptosis by attenuating the expression of NF-kappaB, c-Jun, and caspase-3 in a model of severe hepatic I/R.

The natural history of vascular access for hemodialysis: a single center study of 2,422 patients.

Background: Our objective is to provide provision of primary and secondary patency rates data and incidence of complications. Despite the publication of some review articles and small prospective trials about vascular accesses, controversy still exists regarding the choice of the outflow conduit and especially the choice of the fistula to be formed in secondary and tertiary access procedures.

Methods: This is a retrospective study of 2,422 consecutive patients who underwent 3,685 vascular access procedures in a tertiary care hospital, including radial-cephalic (RCAVF), brachial-cephalic (BCAVF), brachial-basilic (BBAVF), and prosthetic graft (PTFE) fistulas.

Inhibition of intestinal ischemia/repurfusion induced apoptosis and necrosis via down-regulation of the NF-kB, c-Jun and caspace-3 expression by epigallocatechin-3-gallate administration.

Intestinal ischemia/reperfusion (I/R) produces reactive oxygen species (ROS) activating signal transduction and apoptosis. The aim of this study was to evaluate the effect of (-)-epigallocatechin-3-gallate (EGCG) administration in inhibition of apoptosis by attenuating the expression of NF-kB, c-Jun and caspace-3 in intestinal I/R. Thirty male wistar rats were used.

Bilateral Morgagni Hernia: Primary Repair without a Mesh.

We present a case of bilateral Morgagni hernia in a 68-year-old male with an intermittent history of progressive onset of breath shortness and occasional cardiac arrhythmias. Diagnosis was made by clinical examination and the findings in a plain chest radiograph and was confirmed by computed tomography scan. The patient was operated electively and subjected to a transabdominal approach.

Papillomatosis of intra- and extrahepatic biliary tree: Successful treatment with liver transplantation.

Approximately 60 cases of biliary papillomatosis have been reported in the world literature, while only 6 cases have been reported to be treated with liver transplantation. This rare disease, which is characterized by relapsing episodes of obstructive jaundice and cholangitis that lead to secondary cirrhosis and death from sepsis or liver failure, it is also considered premalignant because of its frequent malignant transformation (25-50%). We present a case of a 43-year-old white man with papillomatosis of intra- and extrahepatic biliary tree who sought care for repeated episodes of obstructive jaundice and cholangitis.

Living-related transplantation of an ectopic pelvic kidney.

Ectopic kidneys are usually contraindicated for transplantation as a result of anomalous vascular and drainage system. Graft shortage increases the need of expanding the donor pool and the use of ectopic pelvic kidneys might provide a small but useful source. Transplantation of an ectopic pelvic kidney is a technically demanding procedure and very few cases have been published.

The protective effect of alpha-tocopherol and GdCl3 against hepatic ischemia/reperfusion injury.

Purpose: To evaluate the combined effect of alpha-tocopherol and gadolinium chloride (GdCl3) in reducing lipid peroxidation after severe hepatic ischemia/reperfusion (IR) injury.

Methods: Sixty male Wistar rats, 200-250 g, were randomly divided into six equal groups. There were two sham operation (SHAM) groups, two untreated IR groups, and two IR groups treated with GdCl3 and alpha-tocopherol (IRGT).

Mycophenolate mofetil impairs the integrity of colonic anastomosis.

Background: The aim of this experimental study was to investigate the effect of mycophenolate mofetil (MMF) during the three phases of colonic anastomosis healing and specifically to check the effect of MMF on the expression of transforming growth factor-beta1 (TGF-beta1), one of the most important growth factors contributing to mechanical stability of colonic anastomosis.

Materials And Methods: Sixty male Wistar rats underwent colonic resection and end-to-end anastomosis. The animals were divided into two groups, a study group given MMF 40 mg/kg, intraduodenally and a control group given vehicle.

Attenuation of intestinal ischemia/reperfusion induced liver and lung injury by intraperitoneal administration of (-)-epigallocatechin-3-gallate.

The aim of this study was to evaluate the effect of ( - )-epigallocatechin-3-gallate (EGCG), a natural antioxidant, on liver and lungs after warm intestinal ischemia/reperfusion (I/R). Thirty male Wistar rats were equally divided into a sham-operation group, an intestinal I/R group and an intestinal I/R group pretreated with EGCG intraperitoneally. Intestinal ischemia was induced by occlusion of the superior mesenteric artery for 60 min followed by reperfusion for 120 min.

Intramuscular administration of very high dose of alpha-tocopherol protects liver from severe ischemia/reperfusion injury.

The effect of intramuscular administration of high (30 mg/kg body weight for 3 days) or very high (300 mg/kg body weight for 3 days) doses of a-tocopherol to Wistar rats subjected to total severe warm hepatic ischemia and reperfusion was investigated. After a 60-minute period of total hepatic ischemia and 120 minutes of reperfusion, animals were killed, and liver samples were taken for determination of malondialdehyde (MDA) and histological examinations. Blood samples were also taken for assay of serum a-tocopherol, alanine transaminase (ALT), aspartate transaminase (AST), and lactic dehydrogenase (LDH).
