Usefulness of echocystography in the study of vesicoureteral reflux.

The aim of our study was to assess the usefulness of contrast-enhanced sonography in detecting and staging vesicoureteral reflux in pediatric patients. Forty-nine children between birth and 5 years of age were studied for vesicoureteral reflux. Echocystography with the use of an endovesical signal enhancer was performed first, followed immediately by conventional voiding cystourethrography.

[Clinical usefulness of adrenal gland computed tomography in the etiologic diagnosis of Addison's disease].

Background: The aim of this study was to evaluate adrenal gland morphology by computerized tomography (CT) in the etiologic diagnosis of Addison's disease.

Methods: Twenty-two patients were grouped according to their etiology based on the study of antiadrenal antibodies at diagnosis of the disease: 7 were positive (autoimmune etiology or EAA), 11 were negative (tuberculous etiology or EAT) and in four serologic study was not available (undetermined etiology or EAI). Adrenal gland CT was performed with contiguous sections every 5 mm.
