Simple renal cysts in hypertensive patients: relation between cyst growing and anti-hypertensive therapy.

The study investigates relationship between simple renal cyst enlargement studied by ultrasonography and anti-hypertensive treatment. To this purpose we enrolled 42 patients with newly diagnosed hypertension affected by simple renal cysts. Fourteen were randomly assigned to treatment with ACE-Inhibitors (group 1), twelve to diuretics (group 2) and sixteen to Ca-Antagonists (group 3). Patient performed a basal ultrasonography to evaluate basal cyst dimension before starting anti-hypertensive treatment. Following 12 months of the anti-hypertensive regimen, a new echograph was performed to evaluate changes in cyst size. A control group consisting of 15 patients with normal blood pressure and simple renal cysts was enrolled (group 0). An enlargement of cysts was detected in all patients. However, the enlargement observed in patients treated by Ca-Antagonists was significantly greater than that observed in the other groups (p<0.05). Our study supports the hypothesis that Ca-Antagonists may favor cyst enlargement by enhancing cyclic AMP production. In fact, cAMP and cAMP agonists stimulate fluid secretion by lining cells of the cyst wall, inducing cyst enlargement.

[Cardiac myxoma in the elderly. Clinical study].

Cardiac mixoma in the elderly. A clinical study. The clinical features of 13 cardiac myxomas surgically resected are presented. The mean age at presentation was 68 years. Ten were in the left atrium, 5 near the fossa ovalis, 3 at the base of the atrial septum, 1 at the inferior wall and 1 on the anterior leaflet of mitral valve, 3 were in the right atrium, 1 of these was accompanied with a myxoma at the apex of left ventricle. The ECG and the chest X-ray were normal in 9 and in 8 patients, respectively. In 3 patients, the diagnosis was occasionally made by routine 2-dimensional echocardiography. 5 patients presented with fever of unknown origin, arthralgias, weakness, weight loss. None had intracardiac or extracardiac recurrence in the 73 months follow-up. The presentation with constitutional symptoms only like fever of UO, may mimic collagen and neoplastic diseases, vasculitis, lymphomas: the 2-dimensional echocardiography is mandatory to esclude a cardiac myxoma in the elderly.
