One hundred and seventy Black diabetic patients who regularly attend the Baragwanath Diabetic Clinic were studied. Just over 50% of patients suffered from hypertension, and 10% had angina pectoris. Retinopathy was present in 25% of the patients. The incidence of hypertriglyceridaemia and hypercholesterolaemia was much lower than has previously been found among White diabetic patients in Johannesburg. Attention is drawn to the lack of adequate health education given to Black diabetic patients and also to the reliance on oral hypoglycaemic agents in preference to dietary therapy. It is suggested that there is a need for health educators from the patient's own ethnic group if these problems are to be overcome.

A case of pheochromocytoma of the urinary bladder is reported, and 35 perviously reported cases are analyzed. This interesting entity can present with symptoms of catecholamine excess and severe hypertensive spells (often micturition-induced) or as asymptomatic hematuria without hypertension. The present case represents the severest end of the clinical spectrum, with advancing acute retinopathy and visual loss, very high blood pressure and greatly increased catecholamine excretion. Several special precautions were utilized during diagnostic studies and surgery. On the whole, prognosis is excellent in nonmalignant cases properly handled, and the location of the tumor provides opportunity for early case finding and complete cure.

Comparison of the clinical features, especially prognosis, in cerebral infarction was made between nine normotensive subjects and 16 hypertensive patients with an 80% stenosis or occlusion of the intracranial or extracranial arteries. Our own criteria for evaluating hypertension were employed on the basis of the following items: a past history of hypertension, blood pressure levels on admission and during hospitalization, degree of retinopathy, and ECG changes. In 17 of 25 cases, brain circulation was measured by the intravenous RISA technique. Abnormalities of the EEG and reduction of cranial blood flow were greater, and an early prognosis for neurological deficits in the first two months after the onset of stroke was poorer in the hypertensive group than inthe normotensive group. These results are contradictory to the observations of others.

Life expectancy of diabetics since early childhood is differently judged. Out of 43 own patients with diabetes started between the first and third year of life, no less than 33 have passed their twentieth year of life; 16 patients are aged between 25 and 46 years; one woman patient lived to the age of 64! In all cases the duration of diabetes is more than 10 years, in 26 cases 20 years or more. In 24 cases angiopathy developed chiefly in the form of retinopathy, nephroapthy and arterial hypertension (none in 19 cases). 7 patients died of uraemia. While there is hardly any difference between the two groups (with or without angiopathy) as far as duration and quality of diabetes-control are concerned, in the angiopathy-group hereditary taint clearly prevails. The early beginning of diabetes does not at all represent an absolutely unfavourable symptom, rather the reverse (O. Imerslund).

Amyotrophic lateral sclerosis and Parkinsonism-dementia are unusually prevalent on Guam. Carbohydrate metabolism was studied in 110 patients with evidence diagnostic of or suspecious for these diseases. The combined incidence of known diabetes in 29 per cent of them plus a high percentage of glucose tolerance tests interpreted as abnormal, even when most age-related criteria were considered, was considerably higher than the incidence of abnormal carbohydrate metabolism reported elsewhere in the general population of the United States, the tropical Pacific area, or in recent surveys on Guam itself. The diabetes was generally mild in nature and noteworthy for a lack of retinopathy and other complications. Hypertension, hypercholesterolemia, and hyperuricemia, although highly prevalent, were not consistently associated with abnormal glucose metabolism. Similarly, no consistent association was demonstrated with such factors as age, muscle atrophy, or physical activity.

A report is given on seventeen cases of spontaneous regression of diabetic retinopathy. The diabetes became manifest, without exception, at an early age, particularly in childhood. Regression came on slowly and inconspicuously, retinopathy disappearing completely in two thirds of the cases. Of the other forms of diabetic angiopathy only arterial hypertension was found. No case of specific nephropathy, but frequently chronic infections of the urinary tract, and intermittent proteinuria were observed.

The aim of this study was to evaluate the number, outcome, survival time, and causes of death of patients with severe arterial hypertension who were admitted to the Department of Medicine at Landspitalinn (National Hospital) in Reykjavik during the years 1957 to 1971. During this period 117 patients were found to have severe arterial hypertension (12.6% of all cases of hypertension diagnosed) according to the grading of Keith and Wagener, 20 patients with grade IV retinopathy and 97 patients with grade III. The case histories were analysed according to age and sex distribution, blood urea, electrocardiographic changes, heart size by X-ray at the time of diagnosis and final outcome. The survival calculations were done by the decrement method (life tables) and aim taken from patient age 65 years and less. Relatively fewer patients with severe arterial hypertension were admitted during the last five year period (1967-1971) than during the two previous five year periods. The main causes of death were cerebrovascular accidents (26.6%), myocardial infarctions (22.8%), and renal failure (22.8%). Approximately 50% of the men and 60% of the women survived five years. Elevated blood urea values and signs of left ventricular hypertrophy on ECG at the time of diagnosis carried a more sinister prognosis.

In a population of 744 diabetics composed mainly of elderly female patients, 172 developed hypertension after the onset of diabetes. Compared to normotensive diabetics, they had an increased prevalence of diabetic retinopathy (p less than 0.001), cerebral accidents, ischemic disorders of the lower limbs and a decreased glomerular filtration rate (p less than 0.05); they are frequently insulin-dependent and difficult to manage. In 173 other indivuals the diabetes emerged several years after the hypertension. This group was characterized by relatively easily controlled blood sugar and increased prevalence of angina and myocardial infarction (p less than 0.001). The association of hypercholesteremia with hypertension increases the risk of coronary disease (p less than 0.02) and, to a lesser degree, of glomerular insufficiency. The prevalence of coronary symptoms increases with obesity (p less than 0.05) while retinopathy increases with insulin dependence (p less than 0.001). From this information it may be concluded that the importance of various risk factors in the diabetic chiefly varies according to the vascular territory involved: cerebral vascular accidents occur mainly in hypertensives, while the presence of retinopathies, proteinuria and peripheral ischemia is directly related to the diabetes and particularly to insulin dependence. The risk of coronary lesions increases considerably when hypertension is added to the diabetes, with an even greater risk in the case of a diabetic, hypertensive, hypercholesterolemic nexus.

From two groups of diabetics, i.e. an "invesitgation-group" of 40 cases and a "comparison-group" of 55 cases, the following characteristics of a state preliminary to proliferative diabetic retinopathy are resulting: early commencing of angiopathy by means of proteinuria (nephropathy), progression of retinopathy (pre-stage), pronounced progressiveness of the accompanying nephropathy and arterial hypertension, and finally uncommon diabetic heredo-familiarity. They all permit permature conclusion on proliferative retinopathy (and glomerulosclerosis).

Renal hypertension can usually be recognized only by examining all the features of the hypertensive illness. On the other hand, the investigation of a case of hypertension whose genesis was previously unclear can lead to the diagnosis of a hitherto unrecognized renal disease. The blood pressure values found in patients with renal hypertension are of widely differing degrees of severity. Slight rises in blood pressure (e.g. 140/90 mm Hg), can be a sign of renal disease in adolescent patients. 10-15% of the cases of chronic renal hypertension develop into malignant hypertension. High diastolic values above 120 mm Hg without renal symptomatology and without reduced renal function speak against a primary renal cause of the rise in blood pressure. The finding of hypertension developing during the course of renal disease is, with respect to the hypertensive cardiovascular complications, just as important as in the case of essential hypertension. Complications which can occur during renal hypertension include cardiac insufficiency, hypertensive encephalopathy, retinopathy, hypertensive crises and acceleration of the renal disease.
