Gout disease. Its natural history based on 1,000 observations.

Gout disease in our country as both exogenous factors (dietary habits, professions, etc.) and endogenous factors (sex, inheritance, etc.) play a polygenic role in its incidence. Those conditions resulting in hyperuricemia (diseases, drugs, etc.) facilitate the clinical manifestations. But a genetic determinant in the articular reaction in front of an accumulation of uric acid crystals or in the development of such crystallization is a fundamental factor in the manifestation of the disease. In our series we were able to confirm the high incidence of arterial hypertension, renal lithiasis and renal participation in gout. The role of lead and of certain professions in favouring the hyperuricemia is suggested. A classification of gout, from a functional point of view, must include both the clinical form and the analysis of the whole renal function, and the renal handling of uric acid. This is mandatory not only for the diagnosis and prognosis of the disease but to set the basis of its adequate management.

Calculi↗

[Hypercalciuric and hyperparathyroid renal lithiasis].

Idiopathic hypercalciuria was noted in 10% of a series of 1635 subjects with renal lithiasis. Eight-day administration of thiazide diuretics as a test for the discovery of latent hyperparathyroidism in idiopathic hypercalciuria is described. In 6 cases diagnosed in this way, surgery disclosed the presence of a parathyroid adenoma. Resection was followed by persistent hypercalciuria and, in some instances, renal lithiasis activity. The pathogenesis of associations of these frequently observed diseases is examined.

Adenoma↗

[Nephrolithiasis in hypercalciuria and hyperparathyroidism].

In the group of 1635 patients with nephorolithiasis the authors found 16% with idiopathic hypercalciuria. They administered thiazide diuretics for 8 days as a test for the detection of masked hyperparathyroidism in idiopathic hypercalciuria. In 6 cases which were diagnosed in this manner, the existence of a parathyroidadenoma could be demonstrated by surgical operation. The hypercalciuria persisted after exstirpation of the tumor, in some cases the nephrolithiasis also remained active. the various pathogenetic mechanisms connected with these common diseases are discussed in relation to these results.
