Eighty-four patients with ischaemic stroke aged 18-50 years were analysed. They had been treated in the years 1985-1989. Forty-five of them were followed up. In a high proportion of cases stroke was a result of thrombosis. Many risk factors were found in this group, mainly
hypertension
. In most cases stroke was serious, in several cases post-stroke epilepsy and poly-infarction dementia developed.

QT/QS2 ratio has been assessed in 26 patients with both borderline and mild
hypertension
and mitral valve prolapse syndrome (19 patients), and hyperthyroidism (16 patients) in comparison with method control groups. The following polycardiographic parameters have been analyzed: QT, QTp, QS2, QT/QS2, and QTp/QS2. Higher values of QT/QS2 ratio have been noted in patients with mitral valve prolapse syndrome and hyperthyroidism than that in the control group. There has been no difference in patients with mild
hypertension
while the values of the analyzed parameter have been significantly lower in patients with borderline hypertension. QT has been longer than QS2 (QT)QS2 1/in 9 (56%) patients with hyperthyroidism. A positive correlation between QT/QS2 ratio and ++thyroxine levels have been noted in these patients. QT values have been higher than QS2 values only in 1 patient with mild
hypertension
. It seems that QT/QS2 value has limited value as an indirect index of the adrenergic activity in the dysfunction of the autonomic nervous system.

Totally 510 measures of blood pressure were performed with sphygmo-oscillographic, ultrasound, and auscultation techniques. Sphygmo-oscillography was used for all measurements whereas ultrasound failed in 2.9% and auscultation in 48.2% of cases. Arterial
hypertension
was diagnosed in 24 children, i.e 11%.

Pheochromocytoma was the cause of arterial
hypertension
observed in 0.9% of children treated in 1982-1989. Out of clinical features the most characteristic was sustained
hypertension
often complicated by the accelerated phase of malignant hypertension and encephalopathy. Sustained tachycardia was also found in all patients. Increased urinary excretion of catecholamines and its metabolites confirmed the diagnosis in all cases. The most sensitive and specific methods for tumor diagnosis were ultrasonography and computer tomography of the adrenals while scintigraphy with meta-iodobenzylguanidine+ labelled with iodine-131 radioisotope gave a high percentage of false negative results.

Sodium ions outflow rate through lymphocyte membranes, serum sodium, potassium, aldosterone, total catecholamines and 6-keto-PGE alpha levels, and plasma renin activity were studied in patients with mild
hypertension
associated with low and hugh plasma renin activity treated with captopril in a single dose of 12.3 mg and after the treatment with daily doses of 12.5 mg and 25 mg for 3 days. It was found, that captopril in hypertensive patients with high plasma renin activity decreases both systolic and diastolic blood pressure, decelerates heart rate, and decreases serum total catecholamines and plasma renin activity. Sodium ions outflow rate and serum sodium, potassium, aldosterone, and 6-keto-PGE alpha remain unchanged. Captopril in hypertensive patients with low plasma renin activity. The remaining parameters are unchanged. Moreover, it was noted that serum 6-keto-PGE alpha levels are lower in hypertensive patients with low plasma renin activity.

The investigations were aimed at the objective evaluating of trimetazidine efficacy in the treatment of 30 patients with arterial
hypertension
and ischemic heart disease carried out in non-invasive manner. It was found that trimetazidine complies with several requirements for the effective drug administered to the patients with
hypertension
associated with ischemic heart disease as it: (a) reduces peripheral resistance and exerts favourable effect on the walls tonus of larger arteries; (b) lowers specifically post-exercise arterial pressure and improves resting arterial pressure; (c) reduces demand for oxygen; (d) is safe, and well tolerated by 83% of the treated patients in daily dose of 60 mg.

Definition and classification of the arterial hypertension in pregnancy are discussed. An emphasis is on the problems of differential diagnosis between pre-eclampsia and other forms of
hypertension
. Use of hypotensive drugs in pregnant patients with particular reference to emergencies is also discussed. The treatment of pregnant women with
hypertension
is still a problem which require close co-operation of both an obstetrician and internist. Follow-up after labour is GP duty to find out if the patient remains hypertensive. If so, etiology of the disease should be again searched.

Symptoms and signs in 12 patients with severe obstructive sleep apnea (OSA) syndrome have been presented. The most common symptoms were snoring , increased motor activity during sleep and excessive daytime somnolence. The factors predisposing to OSA syndrome were obesity and anatomic abnormalities of the upper airway structure. In some cases the signs of OSA syndrome included
hypertension
, right heart failure, chronic alveolar hypoventilation and polycythemia. Polysomnography showed sleep fragmentation and the prevalence of light sleep stages. Obstructive sleep apneas repeated 73 +/- 23 times per hour of sleep. The mean apnea duration was 19 +/- 8 s. The mean arterial oxygen saturation during apnea was 72 +/- 14%.

89 patients were operated upon for pheochromocytoma. 61 patients (37 women and 24 men) were available for follow-up. Mean age at operation was 39 +/- 12.3 yrs. Before operation paroxysmal and sustained
hypertension
were observed in 34 (55.7%) and 27 (44.3%) patients, respectively. Postoperatively permanent normalization of blood pressure was achieved in 38 cases (62.3%). All patients were divided into four groups. Group I with increased urine excretion of noradrenaline (NA) and adrenaline (A) consisted of 19 (31.1%) patients. Group II (increased NA excretion) included 27 (44.3%) patients. Group III comprised 3 (4.9%) cases with elevated A excretion. 12 (19.7%) patients with normal urinary excretion of catecholamines and increased excretion of methoxycatecholamines were alloted to group IV. Permanent normalization of blood pressure predominantly was observed in group IV--91.6%, whilst in group I, II and III this hypotensive effect was noted in 57.9%, 51.8% and 2/3, respectively. Permanent normalization of blood pressure can be mainly expected in patients with pheochromocytoma in whom catecholamines are rapidly inactivated within the tumor.

Multi-infarct dementia (MID) and dementia of the Alzheimer type (DAT) are the main syndromes in the elderly. This study aims at evaluating the possible differentiation of these syndromes on a clinical basis. The patient population consisted of demented patients hospitalized during the period April 1, 1988-September 30, 1990 at the Department of Cerebrovascular Diseases. The study included 40 patients with MID and 25 with DAT. The clinical diagnosis of dementia included medical history, neurological examination, psychiatric interview and laboratory diagnostic investigations. The severity of the dementia symptoms was rated by many rating scales and a battery of neuropsychological tests. This model of clinical procedure permitted for differential diagnosis between vascular and degenerative dementia, according to DSM-III-R criteria. Patients with multi-infarct dementia of the Alzheimer type did not differ significantly with regard to age, mean duration of cognitive impairment and level of education. In the DAT group women outnumbered men, and this was statistically significant. It should be emphasized, that a great majority of patients with cerebrovascular lesions developed early cognitive impairment, that means within the first year after stroke. In the MID group
hypertension
, heart disease and smoking were statistically more frequent than in the DAT group. For the preliminary evaluation the severity of cognitive impairment was quantified by Mini-Mental State and Dementia Scale. These scales showed that the degree of dementia was significantly greater in DAT patients as compared to MID patients, whereas the severity of depression assessed by Hamilton's Scale was mild and similar in both group.(ABSTRACT TRUNCATED AT 250 WORDS)
