[Tridimensional ultrasonography in andrology].

Three-dimensional ultrasound has already been employed to improve detection and characterization of the masses in various organs. The system can also be expected to improve qualitative evaluation of vessel pathology. Three-dimensional ultrasound could offer an additional contribution even in Andrology, in at least three fields: in the best evaluation of the anatomical structures; in most accurate measurement of the volumes of the organs; in the study of the Peyronie's disease, for the availability of the coronal plain.

Effects of short-time insulin suppression on renal sodium excretion in type II diabetic hypertensives.

The effects of a short-time insulin suppression on Na+ excretion were evaluated in 9 type II diabetic hypertensive males. All patients had a body mass index < 26 and normal plasma lipid levels. After 2 weeks under constant NaCl intake (120 mEq of NaCl daily) either octreotide, a somatostatin analogue, or its vehicle were infused in a forearm vein during acute volume expansion (0.
