One of the major problems being researched and studied by the World Health Organization is the incidence of harmful side effects in users of steroid contraceptives. A literature search indicates that Anglo-Saxon countries report alarming hyperplastic changes, particularly in the liver, blood clots, hyperlipidemia leading to
high blood pressure
, porphyria, atypical leiomyomas and cervical hyperplasia. Currently attention is being focused on the relationship between steroid contraceptives and breast cancer. Fazala and Paffenbarger in their study of 1770 women found such benign changes as fibroadenoma, mastopathia fibrosa cystica and papilloma intraductale. In women who had used oral contraceptives for 2-4 yrs, malignancies were 1.9% to 2.5% more frequent than in non-users; in 6 yrs of use, 11 times greater than in non-users. Estrogens, particularly mestranol has been recognized as being harmful to the liver. Length of usage is a definite factor. Beginning with 1960, relatively frequent occurrences of hepotoma in young women on the pill were noted. Caught at an early stage, peliosis hepatis can be reversed if the patient discontinues the use of contraceptives. In some cases, even after a long interval of 6 months to 10 yrs, the disease continued to develop. Liver cell adenoma in the U. S. occurs 1/500,00 to 1/1,000,000. After 5 to 7 yrs of using oral contraceptives, the chance of developing liver cell adenoma is 5 times greater; after 10 yrs of use, 35 times greater. Hepatomas rupture in 43.4% of cases when the patient had been on a contraceptive, while in only 22.2% in cases of non-users. The literature which the author investigated did not establish a clear proof that the hyperplastic changes discussed were due exclusively to usage of oral contraceptives.

Risk factors were compared in 300 patients with brain stroke and 120 patients with neurosis or sciatic pains. It was found that arterial
hypertension
(p = 0.001) and diabetes (p = 0.01) were significantly more frequent in cases of brain stroke. Disturbances of lipid metabolism, tobacco smoking and obesity showed no significant difference. Extracerebral atherosclerosis (p = 0.001) increased the risk of stroke. Coronary arterial disease was most frequent (48.8%), myocardial infarction (8.3%) and calcifications in the aorta (32%) were second and third in frequency. Presence of at least two risk factors may be an indication to prophylactic treatment.

A case of epiphyseal tumour diagnosed by means of positive-contrast ventriculography in a male patient is reported. Treatment included ventriculoatriostomy and radiotherapy. In the clinical picture of the disease signs of intracranial
hypertension
prevailed together with hypothalamic endocrine disturbances, and in view of absent pathognomonic signs of lamina quadrigemina lesion considerable difficulties were encountered and craniopharyngioma was suspected. In the light of the pertinent literature and the present observations the possibility of early diagnosis of epiphyseal tumours based on disturbances of vertical optokinetic nystagmus and changes in auditory tests deserves attention.

An unusually severe and uncommon clinical syndrome of migraine with complications in a boy treated during 9 years is described. Severe attacks of migraine were associated with changing cerebral function defects, prolonged disturbances of consciousness, and significant symptoms of intracranial
hypertension
. Vertebral angiography demonstrated disturbances in cerebral circulation.

The activity of acetylcholinesterase was assessed in the rat brain in nephrogenic
hypertension
and after angiotensin administration. No significant differences were found in relation to corresponding control groups.

5-hydroxydopamine, unspecific centrally acting false neurotransmitter. Acta Physiol.
Pol
., 1977, 28 (1): 13-22. 3,4,5-trihydroxyphenetylamine-5-hydroxydopamine (5-OHDA) injected intracerebro-ventricularly decreases the level of noradrenaline, 5-hydroxytryptamine and 5-hydroxyindoleacetic acid in different parts of the rat brain. It does not affect acetylcholine level. 5-OHDA causes dose-dependent hypothermia, transient
hypertension
and depression of locomotor and exploratory activity in rats. This behavioral phenomena are reversed by central chemical sympathectomy elicited by 6-hydroxydopamine. It is concluded that 5-OHDA is an unspecific centrally acting false transmitter.

The authors analysed clinically 108 patients (61 males and 47 females), aged below 50 years treated at the department of neurology, because of acute cerebral ischaemia. Attention is called to risk factors such as arterial
hypertension
, heart disease, atherosclerosis, obesity and diabetes which may be the cause of earlier development of ischaemic changes in the central nervous system. In the analysed group in 18 cases cerebral thrombosis, in 23 cases embolism, in 31 cerebral circulatory failure were diagnosed. In 36 cases the cause could not have been established.

Extracranial
hypertension
was produced in cats by means of epidural compression with a baloon. After 2 hours of compression sudden decompression was performed and tissue pressure was compared at symmetrical sites of cerebral hemispheres with cerebrospinal fluid pressure measured in the cisterna magna. It was found that symmetrical tissue pystem, which was due probably to early oedema developing in the compressed area.

Experimental
hypertension
was induced in rats by two methods. In the course of
hypertension
development the rats of experimental groups were treated with following tricyclic antidepressive agents: Imipramine, Opipramol, Amitriptylline and Nortriptylline injected in doses of 5.0 or 0.5 mg per 1 kg of body weight. Higher doses of the above drugs inhibited the development of
hypertension
, whereas the lower doses had no effect on arterial blood pressure.

The case of a 35-year-old woman who demonstrated androgenic obesity, absence of ovulation, and amenorrhea is examined. This patient showed arterial
hypertension
, diabetes mellitus, hirsutism, and anovulatory cycles. A very high concentration of estrone was noted in the urine, originating in the adrenal glands. These indications are generally considered during evaluation of breast or uterine cancer threat. Administration of dexamethasone led to a decrease in urinary estrone to insignificant levels. Stimulation with human chorionic gonadotropin caused an increase in ovarian activity. The disruptions this patient suffered were attributed to hormonal imbalances attributed to her obesity, primarily in regard to estrogen metabolism.
