adrenocortical tumors (acts) are extremely rare in infants. pediatric acts are therapeutic and diagnostic challenge because histological criteria for distinguishing benign from malignant tumors seen in adults are not always reliable in children .the aim of this report was to present clinical features, hormonal profile, and histopathological characteristics of an infant with adrenal tumors. a 10...

This study examines the hypothesis that the renal prostaglandins function as essential mediators in stimulus-secretion coupling for one or more of the basic receptor mechanisms in the control of renin release. Changes in plasma renin activity (PRA) were evaluated in response to suprarenal aortic constriction before and after indomethacin administration in conscious dogs with either a single den...

Some authors doubt the occurrence of a primary hypernephroma of the ovary and consider ovarian tumors resembling the classic renal hypernephroma as having arisen from lutein cells. Others, emphasizing the sharp differences between the development and arrangement of lutein cells and those of the socalled ovarian hypernephroma, accept the latter as a tumor entity, without reserve. At the present ...

Adrenal vein sampling (AVS) is fundamental for subtype diagnosis in patients with primary aldosteronism. AVS protocols vary between centers, especially for diagnostic indices and for use of adrenocorticotropic hormone (ACTH) stimulation. We investigated the role of both continuous ACTH infusion and bolus on the performance and interpretation of AVS in a sample of 76 patients with confirmed prim...

BACKGROUND Renal insufficiency is the most frequent complication of surgeries that involve suprarenal aortic cross-clamping. Although some studies have assessed the risk of intraoperative renal ischemia by comparing juxtarenal abdominal aortic aneurysms (AAAs) and infrarenal AAAs, a critical limitation is the difference in these patients' clinical backgrounds and aneurysmal features. The presen...
