Three hundred and thirty one carotid endarterectomies were performed on 279 patients during a period of twenty years from 1965 to 1984. The indication for surgery was transient ischemic attack in 67.4%, stroke in 22.7% and asymptomatic carotid stenosis in 10.0% of the operations. The overall major cerebral complication rate attending the operation was 9.6%. During the last four years' period from 1981 to 1984 the procedure morbidity was 3.6% and there was no mortality. Postoperative complications comprised 31 ipsilateral strokes and one contralateral stroke; the complications occurred during the first 24 hours in 28 cases and on the fourth or fifth day in four cases. Of these patients 11 succumbed to internal carotid thrombosis, one to cerebral infarction without thrombosis and one to intracerebral hemorrhage. The associated factors for major complications were analyzed retrospectively in the light of 32 parameters. Patients of advanced age, patients with type II diabetes mellitus, elevated serum triglycerides, high-grade stenosis or occlusion of the contralateral carotid artery, negative smoking history and those undergoing a second operation proved to be at high risk of early postoperative cerebral complications. These complications can be reduced by intraoperative use of heparin, preoperative ASA treatment and a short clamping time. Also peroperative use of shunt is obviously of benefit.

In the longitudinal Schwabing study, unselected insulin-treated diabetic patients were followed for major vascular complication (MVC) (stroke, myocardial infarction, gangrene) and asymptomatic, early detectable peripheral vascular disease (PVD). In the group of insulin-treated NIDDM multiple logistic regression analysis revealed the number of daily injected insulin units as a significant predictor for MVC and PVD (t = 1.98; p less than 0.04; x +/- S.D.: PVD yes 57.6 +/- 21.4 U/d; PVD no 44.3 +/- 17.7; age-adjusted univariate p less than 0.001). Daily insulin dose correlated highly significantly with serum triglycerides (r = 0.40, p less than 0.001) as well as with blood glucose (r = 0.33, p less than 0.001). These data suggest that insulin resistance is characteristic for atherosclerotic disease in NIDDM and the hyperinsulinemia-hypertriglyceridemia-syndrome might be a powerful cardiovascular risk factor in diabetes mellitus.

From a telephone survey of the health status of a random sample of the general population of Utah, we identified 255 people with adult onset diabetes. We compared them to 622 non-diabetic controls, matched for age, sex, and urban/rural country of residence. We examined diabetes as a risk factor for heart diseases, stroke, and blindness and its interaction with other known risk factors. Diabetes interacted with smoking history so as to increase the risk of stroke, heart disease, and blindness. Diabetes also interacted with hypertension in their effect on the prevalence of blindness and, to a small extent, heart disease. Among the diabetics, duration of diabetes was associated with macrovascular and microvascular complications developing after the diagnosis of diabetes. Those with longer duration of disease showed an increase in risk for microvascular (kidney disease, blindness) and macrovascular (heart disease, stroke, amputations) complications. Although the estimates were imprecise, the effect of duration on macrovascular complications was greater among diabetics with a history of hypertension; the effect on microvascular complications was greater among smokers. The findings are compared to previous studies and the utility of diabetes prevalence data is discussed.

Myocardial dysfunction in diabetes mellitus is reversed by proper correction of metabolic changes. To assess the role of hyperglycemia on cardiac dysfunction, 50 g of dextrose were intravenously infused to 15 subjects with stable type 2 diabetes. Echocardiographic measurements were made at 0, 60, 120, 180, and 240 minutes. In spite of the high levels of blood glucose reached in diabetics, left ventricular ejection fraction, fractional shortening, and stroke volume did not experience significant changes. Moreover, cardiac output significantly (p less than 0.01) increased in diabetics secondary to an increase in heart rate. No cardiac changes were noticed in 7 healthy subjects studied in a similar fashion. However, their induced hyperglycemia was not as elevated as in the diabetic patients. These results suggest that acute induced hyperglycemia per se does not appear to impair left ventricular contractility in diabetics at resting conditions.

To examine the mechanism of cardiac dysfunction in diabetes, total circulating blood volume, cardiac and stroke volumes were measured by radioisotope method in 44 patients with type 1 and type 2 diabetes. Considerable difference in actually circulating blood volume could be demonstrated in diabetic patients, which seemed to be dependent on the control of the carbohydrate metabolism. The achievement of well controlled carbohydrate metabolism in diabetics has a great importance with special respect also to the blood volumes.

A quantitative analysis of the cardiovascular risk factors in 101 stroke patients and their reduction by dietary treatment is given. From the risk factors a risk index was calculated. It was reduced from an average 4.9 at admission to 1.4 at discharge. The most frequent risk factors at admission (high triglycerides, high blood pressure and a high LDL/HDL ratio) are probably caused by 'normal' alcohol consumption and overweight. All patients were disused from smoking and alcohol. Under a low-caloric diet all risk factors were reduced within one month. Most diabetic patients became independent of drug treatment: A treatment of type II diabetes mellitus with oral antidiabetic drugs could be avoided even in the elderly patients by a low caloric diet without alcohol. On average there was a 4.8 mg% decrease of fasting triglycerides and a 5.7 mg% decrease of total cholesterol per 1% Broca Index reduction. HDL was increased in all patients despite withdrawal of alcohol, and the HDL/LDL ratio was significantly improved by the diet. There was a significant blood pressure reduction in the whole group; in addition there was a weight-related reduction in the hypertensive patients only: the systolic blood pressure was reduced by 9.3 mm Hg for each 10% Broca Index decrease. The atherogenic and hypertensive potencies of 'normal' alcohol consumption and sulfonylurea treatment are emphasized.

A 60-year-old black male with a 13-year history of adult onset diabetes mellitus and hypertension with a previous lacunar stroke suddenly developed a periodic head and eye movement disorder characterized by nonalternating skew deviation, rotatory nystagmus, head tilt, and lid retraction. On CT scan, the patient had a lacunar infarct in the right midbrain in the region of the interstitial nucleus of Cajal, an anatomical area involved with head tilt, torsional eye movement, and skew deviation.

The prevalence of glaucoma and ocular hypertension was investigated in an epidemiological study of diabetics traced by registration of prescriptions on insulin and oral hypoglycaemic agents (OHA) on the island of Falster (inhabitants 44 498), Denmark. Among 533 diabetics (227 insulin- and 306 OHA-treated) the prevalence rate of primary open angle glaucoma and ocular hypertension was 6.0% and 3.0%, respectively. Neovascular glaucoma occurred in 2.1% of all diabetics and in 21.3% of diabetics with proliferative retinopathy. Open angle glaucoma was more prevalent (P less than 0.01) in type 2 diabetes mellitus compared with type 1 diabetes mellitus. No difference in the prevalence of neovascular glaucoma was found between type 1 and type 2 diabetics. The occurrence of open angle glaucoma correlated positively (P less than 0.01) to the current age (greater than 65 years) in both groups and the diabetes onset age (greater than 40 years) in insulin-treated diabetics. Neovascular glaucoma correlated positively (P less than 0.05) with diabetic macrovascular complications in total (myocardial infarction, ischemic heart disease, arterial hypertension, cerebrovascular stroke, gangrene/amputation), neuropathy and severe microvascular complications (proliferative retinopathy, retinovascular occlusion). Diabetics with open angle glaucoma and ocular hypertension showed a higher frequency (P less than 0.05) of ischemic heart disease, arterial hypertension and retinovascular occlusion compared with diabetics without glaucoma or ocular hypertension.

We screened 214 Japanese NIDDM (non-insulin-dependent) diabetic patients with a family history of diabetes for mutations in the mitochondrial tRNA(Leu(UUR)) gene using polymerase chain reaction-restriction fragment length polymorphism and direct sequencing. Six patients were identified as having an A to G transition at position 3243 (3243 mutation), but no patients were detected with a T to C transition at position 3271, in the mitochondrial tRNA(Leu(UUR)) gene. These two mutations were not present in 85 healthy control subjects. It was disclosed that the patients' mothers were also affected by diabetes mellitus in five of the six cases. In these six affected patients, the 3243 mutation shows variable phenotypes, such as the degree of multiple organ involvement, intrafamilial and interfamilial differences in disease characteristics, and the degree of the involvement of MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes) phenotype. Endocrinological examinations revealed that those diabetic patients with the 3243 mutation show not only beta-cell dysfunction, but also a defect in alpha-cell function, which is considered characteristic of diabetes with the 3243 mutation. When compared with 50 selected diabetic control subjects without the 3243 mutation, whose mothers, but not fathers, were found to have diabetes, it was established statistically that those with the 3243 mutation possess the following clinical characteristics; 1) the age of diabetes onset is lower, 2) they have lean body constitutions, and 3) they are more likely to be treated with insulin than control subjects. We suggest that diabetes with the 3243 mutation possesses phenotypes distinct from those in common forms of diabetes.

A cross-sectional study of 1385 Saudi females attending 15 health centres in urban and rural areas in the Riyadh region was conducted during September and October 1992 to determine the prevalence of obesity and its associated factors. The mean age was 32.2 +/- 11.7 years and body mass index (BMI) 29.2 +/- 7.0 kg m-2. Only 26.1% of subjects were their ideal weight (BMI < 25 kg m-2), while 26.8% were overweight (BMI 25-29.9 kg m-2), 41.9% were moderately obese (BMI 30-40 kg m-2) and 5.1% were morbidly obese (BMI > 40 kg m-2). High-risk groups for obesity were mostly middle aged, multiparous housewives. Patients living in rural areas had greater BMIs than those living in urban areas (P < 0.01). Thirty per cent of overweight participants did not think they were overweight. The study emphasizes the need for community based programmes for preventing and reducing obesity since weight control is effective in ameliorating most of the disorders associated with obesity such as Type 2 non-insulin dependent diabetes mellitus, hypertension, stroke, heart disease, sleep apnoea syndrome and osteoarthritis of the knees. The focus of efforts should be directed towards young mothers who are at risk of developing obesity and who play a central role in perpetuating it in their offspring.
