[Differential diagnosis in hypokalemia. A case of Liddle syndrome].

A case of Liddle's syndrome showing weakness, hypertension, metabolic alkalosis and hypokalemia, identifiable as Liddle's syndrome, allows us to face the differential diagnosis among ionic dysfunctions, as primitive and secondary hyperaldosteronism, hypercorticism and pseudohyperaldosteronism. We discuss hypokalemia due to reduced potassium pool, or referable to altered ionic redistribution without losses. Concerning the treatment of important hypokalemia, we face manners and times of intravenous administration of potassium salts, potassium-sparing diuretics and supplementation per os; besides, we stress the dietetic contribution of rich in potassium foods, for the correction of the light hypokalemia and against deficit of pool referable to the long-term diuretic therapy.

[Etiopathogenesis and clinical aspects of nephrolithiasis--at present].

This paper deals of kidney stones, hard concretions that grow within the urinary tract, 71.5% of which have calcium contents. A high rate of recurrences underscores the importance of medical prevention with a variety of conservative (increased fluid intake and dietary modifications) and drug therapy (potassium citrate, potassium magnesium citrate, thiazides, allopurinol).
