Randomized Controlled Trial
Enhancing the survival of tunneled haemodialysis catheters using an antibiotic lock in the elderly: a randomised, double-blind clinical trial.
Tunneled-cuffed catheters (TCC) are often used among the elderly to commence and carry out haemodialysis (HD). Complications like infection and thrombosis frequently reduce the lifespan of TCC. The role of an antibiotic heparin 'lock' in the prevention of thrombotic and infectious complications and enhancement of TCC survival in the elderly has not been investigated previously. ⋯ Cefotaxime and heparin locks safely and effectively enhance the lifespan of TCC by lowering the incidence of thrombotic and infectious complications among elderly end-stage renal failure (ESRD) patients.

Post-transplant lymphoproliferative disorder (PTLD) following solid organ transplantation is an important form of post-transplant malignancy. PTLD is typically associated with Epstein-Barr virus (EBV) and occurs in the setting of profound immunosuppression resulting in a deficiency of EBV-specific cytotoxic T lymphocytes (CTL). Predisposing factors include EBV mismatch between donor and recipient, use of immunosuppression especially T-cell depletive therapies and genetic predisposition of recipients. ⋯ Recent work has highlighted a potential role for dendritic cells in both the pathogenesis and treatment of PTLD. Current treatment modalities include adoptive immunotherapy using ex vivo generated autologous EBV-specific CTL or allogeneic CTL, cytokine therapies, antiviral agents, and more recently, rituximab and dendritic-cell based therapies. This review focuses on the developments and progress in the pathogenesis, diagnosis and treatment of PTLD.

Case Reports
Rhabdomyolysis following laparoscopic radical nephrectomy: a case to heighten awareness.
Rhabdomyolysis, myoglobinuria and acute renal failure are rare complication of surgery. Long operative time, increased body mass, lateral decubitus positioning and extracellular volume depletion may predispose to this condition. ⋯ His postoperative course was complicated by acute renal failure due to rhabdomyolysis. Heightened awareness, early recognition and treatment of this condition are important, particularly as laparoscopic nephrectomy is becoming a common procedure for living donor transplantation.

Infections are one of the most important risk factors for the development of acute renal failure (ARF) and ventilator-associated pneumonia (VAP) has been reported as one of the most frequent infection in intensive care units (ICU). Sepsis, shock, multiorgan dysfunction syndrome (MODS), use of nephrotoxic antibiotics and mechanical ventilation are potential risk factors for development of ARF during VAP. The objective of the study was to evaluate the incidence of ARF in patients with VAP and the role of VAP-related potential risk factors in the development of ARF. ⋯ These results showed that the incidence of ARF is high during the VAP episodes and that VAP developed with multidrug resistant pathogens and sepsis have an independent effect on the development of ARF.

This study has been carried out to see whether renal function is acutely altered in patients undergoing sevoflurane anaesthesia. For this purpose, the urinary levels of markers of renal tubular function, namely leucine amino peptidase (LAP), gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and beta-2 microglobulin (beta-2M), and urinary albumin as a predictor of renal glomerular function were measured before and after sevoflurane anaesthesia. ⋯ These results suggest that a 2% end-tidal concentration of sevoflurane at a high flow-rate (6 L/min) acutely alters renal glomerular function but does not have a significant acute effect on biochemical markers of renal tubular damage.
