[Functional cardiovascular disorders in patients with neuroses at rest and during physical loading].

The authors examined using selected non-invasive cardiological examination methods 33 patients with neurosis. Four were eliminated on account of organic heart disease. From the group of 29 patients 12 had ECG changes (41%)--of those 5 (17%) had an incomplete right bundle branch block and 1 (3%) had a left anterior fascicular block; 2 (7%) had the syndrome of early repolarization and 4 (14%) had changes of the T wave.

[Echocardiographic diagnosis of myxoma in the left side of the heart].

Echocardiographically established tumors occurring in the left side of the heart in three female patients are described. Two patients had myxoma in the left atrium and one patient presented with a rarely occurring pseudomyxoma in the left ventricle. Two patients were operated on and the echocardiographic finding was verified topically and histologically.

[The prolactin and TSH response to stimulation in patients with hypophyseal tumors].

The authors examined the prolactin (PRL) and thyrotropin (TSH) response to stimulation with chloropromazine and thyreoliberin in 10 patients with pituitary tumours. They observed a hypothalamic response instead of the expected pituitary response. These findings may be of importance for the understanding of the aetiopathogenesis of pituitary tumours.

[Changes in fibrinolysis in diabetes mellitus].

The authors examined in a group of 165 diabetics and 50 healthy subjects the basal fibrinolytic activity after venostasis and in a selected group of diabetics also after stimulation with adiuretin. They revealed not only a retarded fibrinolytic activity in diabetics with angiopathy, as compared with healthy subjects, but also a significant deterioration of the response in this group to stimuli such as venostasis and adiuretin. The authors draw attention to the fact that changes of the fibrinolytic activity which were more marked in diabetics with angiopathy may be conditioned not only by age, the duration of the disease and the elevated inhibitors of plasma fibrinolysis but also by a poorer release of the tissue activator plasminogen.

[Plasma renin activity, creatinine and uric acid in the serum of patients with essential hypertension].

The authors examined the plasma renin activity (PRA), serum uric acid and creatinine in 53 patients with essential hypertension (EH). They recorded low renin EH in 28%, normorenin EH in 53% and high-renin EH in 19% of the hypertensive patients. Assessment of basal PRA levels does not suffice for the classification of EH because the PRA response after stimulation is not related to its basal values.

[2-dimensional echocardiography of mitral stenosis in patients 60 years of age and older].

The authors examined 28 patients with mitral stenosis aged 60 years or older, incl. 20 (71%) with atrial fibrillation and 14 (50%) who had moreover signs of heart failure. None of them suffered from severe mitral stenosis with an area of the mitral orifice smaller than 1 sq.

[Use of suprasternal imaging with 2-dimensional echocardiography in adults].

The authors demonstrate the justification of the suprasternal approach from the hollow of the neck in routine two-dimensional echocardiographic examination in adult patients. Echocardiographic and angiographic imaging is documented in two patients after surgery for coarctation of the aorta, with the narrowed section of the arch of the aorta well visualized, and in the third patient with partial anomalous opening of the pulmonary veins, the dilated left innominate vein draining blood from the left vertical vein into the dilated upper vena cava was clearly visible.
