Young woman with nutcracker syndrome without main clinic manifestation: Hematuria-Case report.

Introduction: The nutcracker syndrome occurs due to the compression of the left renal vein between the aorta and the superior mesenteric artery. The diagnosis of the syndrome is often difficult and under diagnosed. The main clinical manifestations are hematuria and pelvic or back pain.

[Severe idiopathic hyponatremia caused by ADH inappropriate secretion in the elderly].

We report on seven elderly patients with severe hyponatremia (plasma sodium < 125 meq/l). All were symptomatic for central nervous system disturbances, weakness, nausea/vomiting and met clinical and laboratory criteria for the diagnosis of inappropriate secretion of antidiuretic hormone (SIADH). Investigations performed to determine the etiology of the syndrome gave negative results, so that the form was considered to be idiopathic.

Analgesic effect of subcutaneous administration of oxygen-ozone. A blind study in the rat on the modulation of the capsaicin-induced edema.

The Authors have explored a new complementary approach, employed in the last 40 years for, among other uses, medical purposes: oxygen-ozone therapy. Anecdotal works have highlighted interesting results obtained in disk herniation with infiltration of paravertebral muscles with oxygen-ozone. To verify the existence of a nociceptive effect and investigate a possible mechanism of action, an experimental model of edema induction by subcutaneous capsaicin injection in the rat paw was employed.
