Laparoscopic Fixation for Torsion of Transplanted Kidney: A Case Report.

Background: Kidney graft torsion and subsequent acute kidney injury is a rare yet potentially devastating complication of intraperitoneal kidney transplant. We report a case of this elusive diagnosis and describe kidney salvage by using laparoscopic fixation.

Case Report: A 49-year-old male patient presented with multiple episodes of anuric acute kidney injury 16 months after an uneventful combined orthotopic liver and kidney transplantation.

Sequential liver and kidney transplantation from a single living donor in two young adults with primary hyperoxaluria type 1.

Using living donor organs for sequential liver and kidney transplantation (SeqLKT) in patients with primary hyperoxaluria type 1 (PH1) has emerged as a viable approach. Taking both organs from a single donor, however, is rare. There are 8 reported cases of SeqLKT in the literature, and in all but 1 case, children were the recipients.

Magnetic resonance cholangiopancreatography for the accurate diagnosis of biliary complications after liver transplantation: comparison with endoscopic retrograde cholangiography and percutaneous transhepatic cholangiography - long-term follow-up.

Biliary complications after liver transplantation remain a serious cause of morbidity and mortality. Direct invasive cholangiographic techniques, endoscopic retrograde cholangiography (ERCP) or percutaneous transhepatic cholangiography (PTC), have procedure-related complications. Magnetic resonance cholangiopancreatography (MRCP) is non-invasive, safe, and accurate.

Postshunt hepatic encephalopathy in liver transplant recipients.

Background: Preexisting spontaneous portosystemic shunts increase the risk of posttransplantation portal vein thrombosis. Portosystemic shunts may also be placed surgically to manage posttransplant portal vein stenosis/thrombosis. Both types may be complicated by hepatic encephalopathy.

Kidney transplantation from pediatric donors: size-match-based allocation.

Use of kidneys from pediatric donors has been associated with worse outcome. We review our 20-yr experience using pediatric kidneys as single grafts in children and adult recipients. Charts review of 29 recipients, transplanted between 1986 and 2005, who received a graft from a donor View Article and Find Full Text PDF

Recurrent hepatitis C virus disease after liver transplantation and concurrent biliary tract complications: poor outcome.

Recurrent hepatitis C virus (HCV) infection is particularly aggressive in the post-liver transplantation setting, with rapid progression of liver fibrosis. Biliary complications remain a significant cause of morbidity following liver transplantation. Post-cholecystectomy biliary strictures are associated with advanced hepatic fibrosis.

Ligand-independent regulation of ErbB4 receptor phosphorylation by activated Ras.

The ErbB family of receptor tyrosine kinases regulates cell growth, differentiation and survival. Activation of the receptors is induced by specific growth factors in an autocrine, paracrine or juxtacrine manner. The activated ErbB receptors turn on a large variety of signaling cascades, including the prominent Ras-dependent signaling pathways.

Neuregulins rescue PC12-ErbB-4 cells from cell death induced by beta-amyloid peptide: involvement of PI3K and PKC.

Neuregulins (NRGs), which are highly expressed in the nervous system, bind and activate two receptor tyrosine kinases, ErbB-3 and ErbB-4. We previously showed that NRG mediates survival of PC12-ErbB-4 cells from apoptosis induced by serum deprivation, tumor necrosis factor-alpha treatment, or H2O2. These effects of NRGs are mediated by the phosphoinositide 3-kinase (PI3K) signaling pathway.

[Pediatric liver transplantation--experience at Schneider Children's Medical Center].

Background: Introduction of segmental graft transplantation from living donors and split livers from cadaver donors has led to major advances in liver transplantation (LTx) in children.

Aim: To report our initial experience with pediatric LTx performed at our center.

Methods: Data collection on all children undergoing LTx between the years 1996-2003 including the analysis of the graft and patient survivals and reports of complications.

Serum cholestasis markers as predictors of early outcome after liver transplantation.

Background: Early cholestasis is not uncommon after liver transplantation and usually signifies graft dysfunction. The aim of this study was to determine if serum synthetic and cholestatic parameters measured at various time points after transplantation can predict early patient outcome, and graft function.

Methods: The charts of 92 patients who underwent 95 liver transplantations at Rabin Medical Center between 1991 and 2000 were reviewed.

Kidney transplantation from living-unrelated donors: comparison of outcome with living-related and cadaveric transplants under current immunosuppressive protocols.

Objectives: Living-unrelated donors may become an additional organ source for patients on the kidney waiting list. We studied the impact of a combination of calcineurin inhibitors and mycophenolate-mofetil together with steroids on the outcomes of living-related (LRD), unrelated (LUR), and cadaver transplantation.

Methods: Between September 1997 and January 2000, 129 patients underwent LRD (n = 80) or LUR (n = 49) kidney transplantation, and another 173 patients received a cadaveric kidney.

Kidney transplantation from living donors: comparison of results between related and unrelated donor transplants under new immunosuppressive protocols.

Background: Recent advances in immunosuppressive therapy have led to a substantial improvement in the outcome of kidney transplantation. Living unrelated donors may become a source of additional organs for patients on the kidney waiting list.

Objectives: To study the impact of the combination of calcineurin inhibitors and mycophenolate-mofetile, together with steroids, on outcomes of living related and unrelated transplants.

Mucormycosis of the renal allograft: case report and review of the literature.

Fungal infection is an uncommon complication after renal transplantation. We describe a rare form of mucormycosis in the renal graft. Our method was to review chart data and to perform medline searches.

Defibrotide for the treatment of veno-occlusive disease after liver transplantation.

Background: Veno-occlusive disease (VOD) after liver transplantation is associated with acute rejection and poor outcome. The use of antithrombotic and thrombolytic agents is limited by their toxicity. Defibrotide is a polydeoxyribonucleotide with thrombolytic and antithrombotic properties and no systemic anticoagulant effect.
