Association of dysregulated calcium homeostasis and granulomatous disease is well established. There exist reports in the literature of granulomatous reactions produced by silicones associated with hypercalcemia. In this case series we report four young women that underwent methacrylate injections in gluteus, thighs and calves that developed granulomas with(More)
BACKGROUND Calcific uremic arteriolopathy is a rare and serious disorder characterized by systemic medial calcification of the arteries and tissue ischemia. Most often it is found in patients with chronic renal failure on dialysis and in renal transplant recipients with secondary hyperparathyroidism. METHODS We report six patients with end-stage renal(More)
BACKGROUND Acute kidney injury (AKI) is a common complication after cardiac surgery (CS). Recently, neutrophil gelatinase-associated lipocalin (NGAL) was shown to predict AKI development earlier than serum creatinine, but it is not widely used in clinical practice. Fractional excretion of urea (FeU) has been referred to as a useful tool to discriminate(More)
OBJECTIVES Renal flares are common in lupus nephritis (LN), and class switch is thought to be characteristic. There is no agreement on indications for performing a repeat renal biopsy. Our objective was to retrospectively review patients who had more than one renal biopsy performed on clinical indications, and analyse clinical, pathological and treatment(More)
BACKGROUND Acute renal failure due to viral infections is rare. We assessed the development of acute kidney injury (AKI) in critically compromised patients due to the H1N1 influenza virus. METHODS All patients with a PCR -confirmed diagnosis of H1N1 influenza infection admitted to the intensive care unit between May and July 2009 were retrospectively(More)
H1N1 infection and acute kidney injury in the critically ill Sir, Acute renal failure due to viral infections rarely occurs. We assessed the development of acute kidney injury in critically compromised patients due to H1N1 influenza virus. All patients with PCR-confirmed diagnosis of H1N1 infection between May and July 2009 were retrospectively studied.(More)

BACKGROUND Estimating the dialysis dose is a requirement commonly used to assess the quality of renal replacement therapy (RRT) in patients with chronic kidney disease (CKD). In patients with acute kidney injury (AKI), this value is not always evaluated and it has been estimated that the prescribed dose is seldom obtained. Reports addressing this issue in(More)
BACKGROUND Acute kidney injury (AKI) has increasingly been recognized as an important public health issue due to its rising frequency, its associations with early and late adverse outcomes and its economic burden. METHODS Given the importance of determining the available resources to address this serious issue, the AKI Committee of SLANH conducted a(More)
