The use of hemodialysis temporary dual-lumen catheters is often complicated by infections, which may be a significant cause of death among patients with end stage renal disease (ESRD). The aim of this study was to assess the incidence of bacteremia and bacterial colonization related to non-tunneled, non-cuffed, dual-lumen temporary catheters in patients with ESRD submitted to hemodialysis. ⋯ The high incidence of catheter colonization, the correlation between blood and catheter tip cultures, and the occurrence of frequent cases of asymptomatic bacteremia justify the proposal of routine peripheral blood collections to monitor patients undergoing hemodialysis with temporary dual-lumen catheters.

Valproate-induced hyperammonemic encephalopathy is an unusual but serious complication that may occur in people with normal liver-associated enzyme levels, despite normal therapeutic doses and serum levels of valproate. Here, we describe an adolescent girl who had absence seizure and complained about progressive dizziness and general malaise several days after restarting valproate. Then, she presented vomiting and decreased consciousness three weeks after valproate use. ⋯ Ammonia level and EEG also returned to normal. Possible mechanisms, risk factors and the treatments of valproate-induced hyperammonemic encephalopathy are described. Physicians should consider this possibility when consciousness disturbance occurs in patients treated with valproate.

Randomized Controlled Trial Comparative Study
Effects of normal saline vs. lactated ringer's during renal transplantation.
We hypothesized that normal saline (NS) may have more deleterious effects compared with lactated ringer (LR) in kidney transplant recipients because of the higher risk of acidosis and higher levels of serum potassium. Thus, the aim of this study was to determine the safety of LR if used during a renal transplant. ⋯ Compared with NS, LR infusion may lead to a lower serum potassium level and a lower risk of acidosis, while there is major concern of the hypercoagulable state in these patients.

Randomized Controlled Trial Comparative Study
Predictive factors and therapeutic approach of renovascular disease: four years' follow-up.
There is no consensus about the renal function outcome after revascularization with stenting in atherosclerotic renovascular disease. In the present study, the outcome in BP control and renal function in patients with renovascular disease treated with percutaneous angioplasty and stent placement is compared with the outcome in patients with renovascular disease treated with medical treatment only. Additionally, the impact of oxidative stress and eosinophil count in peripheral blood as predictors of renal function deterioration in renovascular disease irrespective of treatment is investigated. ⋯ Revascularization was not superior to medical treatment in renal survival but had a greater positive impact on blood pressure control. Eosinophil count and oxidative stress were the stronger predictive factors for serum creatinine increase.

Multicenter Study
A multi-center evaluation of early acute kidney injury in critically ill trauma patients.
Few studies have evaluated the epidemiology of acute kidney injury (AKI) in trauma. ⋯ Trauma admissions to ICU are frequently complicated by early AKI. Those at high risk for AKI appear to be older, female, with co-morbid illnesses, and present with greater illness severity. Early AKI in trauma is also independently associated with higher mortality. These data indicate a higher burden of AKI than previously described.
