No metagenomic evidence of tumorigenic viruses in cancers from a selected cohort of immunosuppressed subjects.

The possible existence of yet undiscovered human tumorigenic viruses is still under scrutiny. The development of large-scale sequencing technologies, coupled with bioinformatics techniques for the characterization of metagenomic sequences, have provided an invaluable tool for the detection of unknown, infectious, tumorigenic agents, as demonstrated by several recent studies. However, discoveries of novel viruses possibly associated with tumorigenesis are scarce at best.

De Novo Bladder Urothelial Neoplasm in Renal Transplant Recipients: A Retrospective, Multicentered Study.

Background And Objectives: Renal transplant recipients (RTRs) have a 2- to 7-fold risk of developing a neoplasm compared to general population. Bladder urothelial neoplasms in this cohort has an incidence of 0.4-2%.

[Surgical overview on kidney and pancreas transplantation].

The main purpose of this paper, written by a group of Italian expert transplant surgeons, is to provide clinical support and to help through the decision-making process over pre-transplant surgical procedures in potential kidney recipients, as well as selection of pancreas transplant candidates and perioperative management of kidney recipient. Current topics such as different approaches in minimally invasive donor nephrectomy, methods of graft preservation and treatment of failed allograft were addressed.

Coupled Plasma Filtration Adsorption in Patients with a History of Kidney Transplantation: Report of Two Cases.

Coupled plasma filtration adsorption (CPFA) is an extracorporeal treatment based on plasma filtration associated with an adsorbent cartridge and hemofiltration. CPFA is able to remove inflammatory mediators and it has been used to treat severe sepsis, septic shock and multiple organ dysfunction syndrome. Limited experience exists on the use of CPFA after solid organ transplantation.

Infected Nonhealing Wound in a Kidney Transplant Recipient: Successful Treatment With Topical Homologous Platelet-Rich Gel.

Impaired would healing is a known adverse effect of chronic immunosuppression. Solid-organ transplant recipients undergoing major abdominal surgery have an increased risk of wound-related complications compared with the general population. In this subset of patients, surgical site infections and wound dehiscence must be aggressively treated to avoid sepsis, graft loss, and death.

One-shot versus multidose perioperative antibiotic prophylaxis after kidney transplantation: a randomized, controlled clinical trial.

Background: There is no consensus on the optimal perioperative antibiotic prophylaxis regimen for renal transplant recipients. Some studies have reported that irrigation of the wound at the time of closure without systemic antibiotics may suffice to minimize the risk for surgical site infection (SSI), but many centers still use long-term, multidose regimens in which antibiotics are administered until removal of foreign bodies occur, such as the urethral catheter, drain and central line.

Methods: We designed a prospective, randomized, multicenter, controlled trial to compare a single dose versus a multidose regimen of systemic antibiotic prophylaxis in adult, nondiabetic, non-morbidly obese patients undergoing renal transplantation.

Urinary tract reconstruction using the controlateral native ureter and a combined open-retroperitoneoscopic approach after renal transplantation.

An alternative technique for urinary tract (UT) reconstruction is described in a renal transplant recipient who developed a severe stenosis of the graft ureter. This approach entails the retroperitoneoscopic preparation of the native ureter contralateral to the graft, followed by an open reconstruction of the UT. The ureter was dissected along its entire length to the level of the iliac vessels, with its associated mesentery still attached in order to preserve the vascular supply.

Eubacterium plautii infection in a kidney transplant recipient: a noteworthy case of pleural effusion and fever.

We report a noteworthy case of Eubacterium plautii infection after kidney transplantation. Our 33-yr-old transplant recipient received standard care; his post-transplant course was uneventful. However, on day 44 he underwent an emergency laparotomy for perforation of the ileum.

Artificial organs as a bridge to transplantation.

Current organ shortage is estimated to keep outpacing demand for years to come. Among the advocated strategies, artificial and bioartificial devices may prove beneficial to a wide category of patients on transplant waiting lists. Bionic organ science allows to reproduce organ architecture and function through a complex interplay of cellular and mechanical elements.
