Purpose : Considering that renal biopsy is not routinely indicated in nephrotic syndrome in children and the risk of the procedure, we studied that it is possible to predict steroid responsiveness in nephrotic syndrome and the difference in responsivenss is related with the histopathologic type using urinary β2-microglobulin and N-Acetyl-β-D-Glucosaminidase activity as a safe and noninvasive method. Methods : We measured serum creatinine, albumin, cholesterol...

The idiopathic long QT syndrome is a very rare disorder in which affected individuals have an unusual electrocardiographic repolarization abnormality (QT prolongation) and a propensity to syncope and fatal ventricular arrhythmia. Since Jervell and Lange-Nielsen first described this syndrome in 1957, progression has been made in the pathophysiology and in the treatment. Sinus bradycardia may be associated with this syndrome sometimes,...
