Portosystemic shunt, a rare cause of neonatal cholestatic hepatitis. A case report.

Congenital portosystemic shunt is a venous vascular abnormality that connects portal and systemic circulation, resulting in diversion of the blood flow, bypassing the hepatic passage. It is a rare malformation; its incidence varies from 1:30 000 to 1:50 000 newborns. It may be asymptomatic or present with complications in the pediatric age or, less frequently, in the neonatal age.

Treatment of Epstein-Barr Virus-Related Post-Renal Transplantation Development of Diffuse Large B Cell Lymphoma of the Distal Ureter: A Case Report.

Posttransplant lymphoproliferative disorder with involvement of the donor urogenital tissue is a rare and serious complication of solid organ transplant. We report an adult kidney transplant recipient who developed the diffuse large B cell lymphoma of the distal ureter in the setting of new allograft nephropathy. Early intervention, reduction of immunosuppression, surgical reconstruction and chemotherapy salvaged the allograft kidney and averted a fatal outcome.

[Spontaneous intrauterine depressed skull fracture: report of two cases].

Spontaneous intrauterine depressed skull fractures are a rare entity. They can appear secondarily to head trauma (before or during birth) or due to unknown etiology. They usually require a complete evaluation from pediatric neurosurgery specialists.

Preparedness strategies in neonatology units during the COVID-19 pandemic: A survey conducted at maternity centers in Argentina.

Introduction: The objective of this study was to analyze available resources, guidelines in use, and preparedness to care for newborn infants at maternity centers in Argentina during the COVID-19 pandemic.

Method: Cross-sectional study based on a survey administered to medical and nursing staff. In May 2020, Argentine facilities with more than 500 annual births were contacted; 58 % of these were from the public sector.

Disparities in utilization of services for racial and ethnic minorities with hepatocellular carcinoma associated with hepatitis C.

Background: Hepatitis C affects racial minorities disproportionately and is greatest among the black population. The incidence of hepatocellular carcinoma has increased with the largest increase observed in black and Hispanic populations, but limited data remain on whether hepatitis C hepatocellular carcinoma in racial-ethnic minorities have the same utilization of services compared with the white population.

Methods: We used the database of the National Inpatient Sample to identify hepatitis C-hepatocellular carcinoma patients (N = 200,163) who underwent liver transplantation (n = 11,491), liver resection (n = 4,896), or ablation of liver lesions (n = 6,933) from 2005 to 2015.

Urologic Complications in 4000 Kidney Transplants Performed at the Saint Barnabas Health Care System.

Unlabelled: Renal transplantation is the current standard treatment for end-stage renal disease and is associated with immunologic, vascular, and urologic complications. In this study we report urologic complications following ureteral reimplantation based on 1 urologist's experience at a single high-volume renal transplant institution.

Methods: A retrospective review was performed on all patients who underwent ureteral reimplantation by the transplant urologist at the time of their kidney transplant between July 1, 1993, and December 31, 2016.

Outcomes Following Major Oncologic Operations for Non-AIDS-Defining Cancers in the HIV Population: A Matched Comparison to the General Population.

Introduction: Human immunodeficiency virus (HIV) patients are living longer due to the availability of antiretroviral therapies, and non-AIDS-defining cancers are becoming more prevalent in this patient population. A paucity of data remains on post-operative outcomes following resection of non-AIDS-defining cancers in the HIV population.

Methods: The National Inpatient Sample was utilized to identify patients who underwent surgical resection for malignancy from 2005 to 2015 (HIV, N = 52,742; non-HIV, N = 11,885,184).

Vascular constraints in laparoscopic renal allograft: comparative analysis of multiple and single renal arteries in 976 laparoscopic donor nephrectomies.

Background: Since the initial description of laparoscopic donor nephrectomy (LDN) in 1995, the field of renal transplantation has continued to evolve. Although the identification of donor kidneys with multiple renal arteries (MRA) was considered a contraindication to LDN, improvement in the surgical technique to surmount the technical challenges of LDN with MRA have been established as the skill and laparoscopic experience of transplant surgeons evolves with time. Consensus regarding LDN with MRA and recipient outcomes is not uniformly documented amongst the transplant community.

Urologic complications in more than 2500 kidney transplantations performed at the Saint Barnabas healthcare system.

We report our urologic complications based on one urologist's experience during a 17-year period on more than 2500 ureteral reimplantation operations performed at the time of kidney transplant. Among 2548 ureteroneocystostomies performed by the transplant urologist, a 5.5% urologic complication rate was observed.

Successful rescue of refractory acute antibody-mediated renal allograft rejection with splenectomy--a case report.

Highly sensitized patients receive fewer kidney transplants and have a high risk for severe rejection with increased rates of graft loss. We present a highly sensitized child who after desensitization protocol received a kidney transplant and developed refractory acute antibody-mediated rejection. He failed to respond to standard therapy and needed an urgent splenectomy as rescue therapy.

Robotic-assisted laparoscopic donor nephrectomies: early experience and review of the literature.

With over 80,000 patients in the United States awaiting kidney transplantation, renal transplant surgery continues to evolve with attractive surgical options for living donation, which include laparoscopic donor nephrectomy (LDN) and robotic-assisted laparoscopic donor nephrectomy (RALDN). LDN is currently accepted as the gold standard procedure for living donor nephrectomy; RALDN is an evolving technique and may emerge as a preferred procedure over time. We present our initial experience with RALDN from December 2007 to August 2008.

Transporting live donor kidneys for kidney paired donation: initial national results.

Optimizing the possibilities for kidney-paired donation (KPD) requires the participation of donor-recipient pairs from wide geographic regions. Initially it was envisaged that donors would travel to the recipient center; however, to minimize barriers to participation and simplify logistics, recent trends have involved transporting the kidneys rather than the donors. The goal of this study was to review outcomes of this practice.

Impact of laparoscopic donor nephrectomy on allograft function in pediatric renal transplant recipients: a single-center report.

Laparoscopic donor nephrectomy (LDN) is rapidly becoming the preferred technique for the procurement of living donor kidneys. An association of this technique with delayed graft function and higher risk for rejection has been reported in pediatric recipients. We reviewed our experience of 17 pediatric patients who received a living donor kidney, from 2002 to 2004, procured by LDN, and compared it with a matched group that received living donor kidneys harvested by the open technique.

Urologic complications in over 1000 kidney transplants performed at the Saint Barnabas healthcare system.

We report the complication rate based on one urologist's experience over a 9-year period including over 1000 ureteral reimplants performed at the time of kidney transplantation. Among 1083 ureteral reimplant operations, there was a 4.3% urologic complication rate, including a 2.

Hypercoagulable states in renal transplant candidates: impact of anticoagulation upon incidence of renal allograft thrombosis.

Introduction: Although multiple studies of demographic variables have been associated with allograft thrombosis, these results are not routinely reproducible. Are ESRD patients with hypercoagulable states (HCS) (antithrombin III deficiency, protein S or C deficiency, activated protein C resistance, and anticardiolipin antibodies) at predictably greater risk for allograft thrombosis?

Methods: Between 1996 and 1999, all renal transplant candidates were screened for hypercoagulability risk factors [HRF] (multiple arteriovenous access thromboses, prior deep vein thrombosis, prior allograft thrombosis, collagen vascular disease, multiple miscarriages, diabetes, autoimmune disease, and Fabry's disease). HRF(+) candidates were then tested for HCS status.

Nephrogenic adenomas occurring in a patient with simultaneous kidney-pancreas transplant.

We present a female patient who developed multiple nephrogenic adenomas of the bladder about 3 years after a simultaneous kidney-pancreas transplant. The patient was initially treated with endoscopic resection but, due to recurrences, she later underwent a conversion of pancreatic drainage from the bladder to the small bowel and has since done well. We believe this to be the first such case reported in the literature.

Evaluation of voiding cystourethrography prior to renal transplantation.

In many centers, voiding cystourethrography is a routine part of pretransplantation assessment of the lower urinary tract. To assess the value of this investigation, a retrospective review of transplant candidates evaluated in our center over 2 years was undertaken. A total of 517 patients were fully evaluable.

Preliminary experience with split liver transplantation.

Background: The purpose of split liver transplantation is to alleviate the organ shortage for patients with end-stage liver disease. The procedure, however, has not gained wide acceptance. This is related not only to the complexity of the procedure but also to poorer results and the complications reported to be associated with the technique.

Pretransplant status and patient survival following liver transplantation.

The current liver allocation system has been criticized, since available organs go to those who are the most critically ill. These recipients have the poorest overall survival. Identification of pretransplant risk factors for mortality would allow better allocation of donor livers.

Pancreas transplantation.

During the past decade, marked improvement has been made in the field of pancreas transplantation. The best results have been obtained in patients receiving a simultaneous pancreas-kidney transplant using the bladder drainage technique. An overall improvement in the secondary complications of diabetes has been documented in patients receiving successful pancreatic grafts.

Living-unrelated renal donor transplantation: the UNOS experience, 1987-1991. United Network for Organ Sharing.

1. LURD transplants were associated with excellent one-year graft survival of 92%. This survival was superior to that for cadaver transplants performed during the same period.
