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.

The frequency and significance of associated diseases and clinical problems in patients with nerve injuries in the recovery stage was statistically assessed. A variety of clinical situations are observed in practically all such patients. Half of the symptoms and diseases encountered relate to the nervous system and cardiocirculatory apparatus, while there is also a high incidence of skeletal muscle and urinary affections. The significance of these signs as far as rehabilitation is concerned can be seen in the fact that psychological and micturition disturbances are observed, along with muscle hypertonia, fibromyositis, cystitis and arthrosis. These form the more common obstacles to the regular execution of a rehabilitation programme, whereas no such significance is possessed by such serious diseases as valvular cardiopathy, hypertension and neoplasia of the neuraxis.

Blood loss and the incidence of emetic sequelae were assessed in 148 patients undergoing midcavity forceps delivery under continuous lumbar extradural analgesia. Five units of oxytocin i.v. was found to be as effective as ergometrine 0.5 mg i.v. in reducing blood loss at delivery. Nausea, retching or vomiting occurred in 35 (46%) of the mothers who received ergometrine and in none of those who received i.v. oxytocin. The cardiovascular side-effects of ergometrine and oxytocin are reviewed and compared with special reference to patients with hypertension and heart disease. It is suggested that 5 units of oxytocin i.v. should be preferred in these high-risk patients. Because of the absence of an emetic action, i.v. oxytocin is preferable to i.v. ergometrine for patients receiving extradural analgesia.

Pulmonary congestion in chronic heart disease was evaluated by lung auscultation and roentgen examination of the chest and compared with pressure recording of the pulmonary circulation in 49 cases. Whereas auscultation appeared not to be correlated to the pressures, the radiologic findings proved to be a reliable measure of increased pressures. The radiologic assessment was based on isolated flow shift to the upper lobes of the lungs, indicating slight pulmonary venous hypertension, and flow shift in association with blurring of the lower lobe vessels, indicating pulmonary interstitial oedema. In distinction to the results from acute cardiac failure interlobular septa were often demonstrated in association with pulmonary interstitial oedema, and pulmonary alveolar oedema rarely demonstrated in spite of marked pulmonary venous hypertension.

Accumulated literature over the past 25 years about the team approach to chronic disease can be divided into three broad categories: (1) the opinion base which reflects statements of belief and faith, (2) the descriptive base which contains details and personal testimony of programs using team concepts and (3) the study base which includes serious research efforts to investigate the effectiveness of team care in various settings. An analysis of the articles in the last category provides a useful insight into the problems and possibilities associated with this neglected area of health care research. The populations studied include patients with heart disease, hypertension, stroke, hip fracture, rheumatoid arthritis, diabetes and groups referred for comprehensive rehabilitation. The majority of the studies demonstrated improved outcomes in one or more areas for patients receiving coordinated team care when compared with control groups. Although these studies serve as a useful guide, the extent to which the findings can be generalized is open to serious question. In the absence of additional research, team care will remain as it is today, largely a matter of faith and the subject of many platitudes. An outline is proposed of the major methodological features which should be considered in the planning and/or evaluation of future studies in this area.

Factors involved in the development of coronary atherosclerosis and the possible role of estrogens in its development are discussed. Risk factors in the development of atherosclerosis include hyperlipemia, hypertension, cigarette smoking, and diabetes. However, the incidence of heart disease and presence of risk factors are also related to heredity, geography, and socioeconomic conditions, and to diet, exercise, and emotional stress. Contrary to previous belief, high doses of estrogens aggravate the condition of men and menopausal women at risk of heart attack. Although estrogens do not markedly alter cholesterol levels, they do tend to elevate triglyceride levels and contribute to hyperlipemia. They are also associated with diabotegenic sequelae and hypertension. Pregnancy and estrogens increase blood clotting Factors VII and X, accelerate prothrombin time, shorten clotting time, and incre ase platelef aggregation. Further research into the role of estrogens in the development of atherosclerosis is recommended.

Two nationwide registers, the Finnish Cancer Registry and a register of persons entitled to free drugs for hypertension, were linked in a case-control study of the association of breast cancer and use of rauwolfia. Cases were all hypertensive patients in whom breast cancer was diagnosed in 1973. To test the association specifically with rauwolfia, controls were hypertensive women matched with the cases for age and geographic area and approximately matched for duration of treatment for hypertension. There were 109 case-control pairs. Use of any physician-prescribed drugs during the year prior to diagnosis of breast cancer was ascertained from original prescriptions. In the first set of analyses the patients were classified according to the drug used during most days of the year ("main antihypertensive agent"). In the second set a person qualified as a user of the respective drug regardless of the amount taken. The relative risks in the use of rauwolfia, methyldopa, another synthetic antihypertensive or a diuretic as main antihypertensive agent all ranged between 0.90 and 1.11. The results based on use of a drug in any amount were similar. Next, pairs in which duration of treatment for hypertension was different for cases and controls were excluded. The relative risk associated with use of rauwolfia as main antihypertensive agent then increased from 1.00 to 1.30 and the risk associated with use of any amount of rauwolfia from 1.16 to 2.14. Simultaneously, the relative risk in the use of digitalis was raised from 1.33 to 2.67 and of nitroglycerin from 1.00 to 1.71. Cases also used more types of antihypertensive agents simultaneously than controls. There was no association between rauwolfia-use and breast cancer in analyses limited to pairs in which neither case nor control used digitalis. Thus, there was not a consistent drug-specific association between rauwolfia-use and breast cancer in hypertensive patients. An underlying association of hypertension, heart disease or its treatment (digitalis) and breast cancer may have confounded some of the results of this and earlier studies. In conclusion, it is unlikely that use of rauwolfia increases the risk of breast cancer.

157 cases affected with "unstable angina" and hospitalized were observed over a period of from 8 to 24 months (average observation time: 16 1/2 months). The patients were treated with: nitroderivates, beta blocking drugs (when not contra-indicated); treatment of side affects (hypertension; arrhythmias, decompensation, associated pathology, correction of risk factors of coronary heart disease). 9 cases were lost and 148 were studied for the course of the illness. 10.6% died from cardiopathy (2.8% through sudden death; 7.4% from myocardial infarction); there was a 12.1% total incidence of myocardial infarction; 50% of the cases were alive but with sumptoms of stabilized angina, whilst 32.4% were completely asymptomatic. Coronographic alterations and myocardial contractility negatively affect the course of the illness. Negative effects (disease or infarction) were not checked in the cases of stenosis of only one coronary branch. In the casuistry, there were no negative effects in patients with stenosis of one coronary branch, and in cases of two or more branches, negative effects were 28%. 41% of patients with alterations of ventrical contractility gave negative results. An asymptomatic course of the illness was checked more frequently in the intermediate stages than in angina cases.

An analysis of 433 observations is presented (164 cases of isolated pulmonary stenosis, 132 cases of its combination with atrial septal defect, and 137--with ventricular septal defect), the patients being 1 year 1 month to 36 years old, and the form of their heart disease being verified during surgery on a "dry" heart. The mentioned diseases were classified into 3 groups according to the tactical importance of the pulmonary stenosis. Haemodynamic studies in patients with pulmonary stenosis and an intact ventricular septum have demonstrated that with age right-ventricular hypertension progresses the faster the greater the pulmonary artery valve is stenosed. A combination of a valvular stenosis with a large ventricular communication is accompanied by a levelling of the pressure in both ventricles, its absolute figures being somewhat higher in patients over 16 years of age.

A survey was carried out amongst 7062 people of different age groups in Dacca city and in a village. It was found that 207 (2.92%) persons had some sort of heart disease. Hypertension was present in 83 (1.10%) persons. Rheumatic heart disease, ischaemic heart disease and cardiac arrhythmia were detected in 53 (0.75%), 24 (0.33%) and 16 (0.22%) persons respectively. Congenital heart disease was found in 13 (0.18%) individuals, and 18 (0.25%) persons were suffering from cardiomypathy or corpulmonale. Rheumatic heart disease was common in poor people of younger age. More ischaemic heart disease was found in well-to-do people but poor people were not immune from this.
