Controlled Clinical Trial
Urine neutrophil gelatinase-associated lipocalin and interleukin-18 predict acute kidney injury after cardiac surgery.
About 30-50% patients develop acute kidney injury (AKI) after cardiac surgery, which is still diagnosed by serum creatinine on clinic. However, the increase of serum creatinine is insensitive and delayed. The aim of this study is to test the hypothesis that neutrophil gelatinase-associated lipocalin (NGAL) and interleukin-18 (IL-18) are early biomarkers for AKI in patients after cardiac surgery. ⋯ The concentrations of urine NGAL and IL-18 could be useful biomarkers for AKI in patients after cardiac surgery, especially after correction for urine creatinine.

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.

Review of literature revealed no studies about the predominant causes and risk factors of acute renal failure in Jordan. This study identifies the most common causes of acute renal failure and the possible risk factors among hospitalized Jordanian population. A total of 111 patients were admitted to both King Abdullah University Hospital and Princess Basmah Teaching Hospital from December 2005 to April 2006 with a diagnosis of acute renal failure or developed acute renal failure in hospital during their stay. ⋯ Causes of acute renal failure included dehydration, diuretics, sepsis, contrast media, nonsteroidal anti-inflammatory drugs, glomerulonephritis, systemic lupus erythematosus, stones, and others. In conclusion, one-third of the causes of acute renal failure in this sample of hospitalized Jordanian patients were due to drugs, which makes this problem preventable. Mortality was affected by the age of patients and the duration of hospitalization.

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.
