The prevalence of glucose intolerance and diabetic complications was determined in second-generation Japanese-American (Nisei) women and compared to previously obtained results in Nisei men. A volunteer study sample of 191 Nisei women 45-74 years old was enrolled from a study population of 1489 Nisei women born 1913-1942, raised and educated in the U.S., and residing in King County, Washington. The enrolled sample included 72 with normal glucose tolerance, 67 with impaired glucose tolerance (IGT), and 52 with non-insulin-dependent diabetes. A random sample was also drawn from the study population to form a reference sample of 157 women. Based upon observations in the reference and enrolled samples, an estimated 16% of Nisei women in the study population have diabetes and 40% IGT. These rates compare to 20% diabetes and 36% IGT previously estimated for Nisei men 45-74 years old. The prevalence of cardiovascular disease (hypertension, peripheral vascular disease, and/or coronary heart disease) was highest among diabetic women, lowest in those with normal glucose tolerance, and intermediate in women with IGT. In comparison to diabetic men, there was a significantly lower frequency of neuropathy, peripheral vascular disease, and coronary heart disease in diabetic women. However, hypertension occurred equally often in both. Thus Japanese-American men and women 45-74 yr old have a similar prevalence of glucose intolerance, although less severe in women, and complications, except for hypertension, are reduced in women.

907 consecutive patients, (456 Asian and 451 Caucasian) were assessed, employing a similar methodology to the multi-centre WHO study. The Asians were older at diagnosis (46.5 years compared with 40.6 years, P less than 0.01); they had a shorter duration of diabetes (6.3 years versus 11.4 years, P less than 0.1), a higher rate of diabetes in the first degree relatives (29.5% compared with 16%, P less than 0.1), less ketonuria at presentation (85.3% compared with 47.8%, P less than 0.1), and fewer were treated with insulin (31.4% compared with 68.7%). Comparing the prevalence of complications between Asians and Caucasians, the ischaemic heart disease rate was similar; peripheral vascular disease was less (3.7% Asian, 9.3% Caucasian, P less than 0.05); retinopathy was less (11.6% Asian, 32.3% Caucasian, P less than 0.01) but renal disease was more (22.3% Asian, 12.6% Caucasian, P less than 0.01). After adjusting for age, sex, duration of diabetes, age at diagnosis, hypertension, smoking and treatment with or without insulin, these differences remained significant. Multivariate logistic regression failed to reveal a significant contribution due to any of the above variables, or due to body mass index (BMI), haemoglobin A (HbA1), or physical activity in the prevalence of complications in Asians compared with Caucasians. Marked heterogeneity in the complications of diabetes in the two ethnic groups studied was found, but must be confirmed from population-based studies.

To determine the influence of age on atrial fibrillation as a risk factor for cerebral infarction, the Austin Hospital Stroke Unit Register from 1977 to 1990 was reviewed. There were 2279 patients with cerebral infarction (excluding lacunar infarction syndromes) with a mean age of 68.3 years who were identified as subjects, and 800 patients with pseudostroke and lacunar infarction syndromes with a mean age of 64.7 years who were identified as controls. Data concerning potential risk factors for stroke (including sex, age, atrial fibrillation, cardiac disease, hypertension, diabetes, peripheral vascular disease and smoking) were analyzed using multivariate regression techniques. It was found that atrial fibrillation was a significant risk factor for cerebral infarction (excluding lacunar infarction) for all age groups, after adjusting for the effects of other risk factors (P less than .001). However, when age was stratified into four groups, the age-specific odds ratios for atrial fibrillation were not significantly different and no significant interactions between atrial fibrillation and age or other risk factors were found (P greater than 0.1). It was concluded that, although with increasing age atrial fibrillation becomes a more frequent cause of stroke, its potency as a risk factor does not increase correspondingly. There was no significant influence of age on the relationship between atrial fibrillation and cerebral infarction.

In practice, some of the major problems for the physician who treats hypertension are patients who are resistant to treatment or who have other complicating risk syndromes. Therefore the overall efficacy of an antihypertensive agent must include an assessment of effect in patients with serious ancillary problems. In this article, doxazosin is reviewed for its efficacy in the treatment of severe essential hypertension and specific complications or conditions of mild or moderate essential hypertension, namely, left ventricular hypertrophy, hyperlipidemia, noninsulin-dependent diabetes mellitus, renal insufficiency, pheochromocytoma, chronic obstructive pulmonary disease, peripheral vascular disease, and smoking. Doxazosin is particularly efficacious in many specific subgroups of patients with hypertension, and the results of relevant studies are discussed.

As part of our initial evaluation to determine whether patients with lower extremity ischemia are candidates for intervention, arterial duplex examinations are performed in the noninvasive vascular laboratory. Patients with isolated short stenoses on the duplex examination are referred for transluminal angioplasty. One hundred thirty-four arteriograms were performed for ischemic peripheral vascular disease in 122 patients between July 1987 and March 1990. One hundred ten (82%) of the arteriograms were preceded by a lower extremity arterial duplex evaluation. Fifty cases (45%) were scheduled for transluminal angioplasty based on the findings of the duplex examination. Transluminal angioplasty was performed in 47 of 50 cases (94%). No significant differences in age, sex, or diabetes were found between the patients who were referred for transluminal angioplasty and those who were not. These data demonstrate that duplex scanning of the lower extremities allows the detection of lesions that will be amenable to transluminal angioplasty. We think that duplex scanning should become the standard screening tool for detection of treatable lower extremity lesions.

Estimates of the cost of diabetes should take into account the development of complications. Patient records identified from the 1987 National Hospital Discharge Survey were used to evaluate the risk of hospitalization due to late complications. Hospitalization for diabetic nephropathy reached a peak of 6.74/1000 between the ages of 45 and 54 years, compared to 0.14 to 1.80/1000 in controls. Diabetic patients less than or equal to 45 years of age were 46 times more likely to be hospitalized due to neuropathy. The risk of cardiovascular complications is high, with a greater incidence of arterial than venous disorders. Diabetic patients were 22 times more likely to be admitted for skin ulcers/gangrene, 15 times more likely due to peripheral vascular disease, and 10 times due to atherosclerosis. The risk of cerebrovascular accident and heart disease was 6 to 10 times greater in diabetic patients. Seventy-five per cent of diabetic cardiovascular disorders are myocardial infarction or chronic ischaemia. Hospitalization from renal complications occurs at younger ages than in the general population. Ophthalmic complications increase with age. Diabetic complications account for 2% of the total hospital admissions in the US in 1987. The total cost of the treatment of late diabetic complications was estimated at +5091 million (cardiovascular 74%; renal diseases 10%; nephropathy 3.6%; ophthalmic disorders 1.5%; other unspecified diseases 10%).

One hundred and eighty-eight known Type 2 diabetic patients aged over 60 years identified by a geographically based survey of a population of 40,076 were followed for a median of 6 years to determine the incidence of various complications. There were 63 deaths and two patients were lost to follow-up. The presence of complications was determined using a structured questionnaire and clinical examination. Incidence rates of ischaemic heart disease, stroke, and peripheral vascular disease (PVD) were 56 (95% CI 41-75), 22 (13-35), and 146 (117-174) 1000-person-years-1 of follow-up, respectively. Rates of stroke and PVD rose significantly with age. Retinopathy occurred at a rate of 60 (42-83) 1000-person-years-1 and cataract at 29 (17-46) 1000-person-years-1 although visual acuity in survivors did not deteriorate overall, probably reflecting the high mortality associated with cataract. The rate of proteinuria (albumin concentration greater than 300 mg l-1) was 19 (9-34) 1000-person-years-1. Incidence rates were unrelated to sex or duration of diabetes. Diabetes is associated with a continuing incidence of complications into old age. Adequate facilities are required to assess and treat the resulting morbidity in a population with an increasing proportion of elderly people.

An open cross-sectional study of elderly (age greater than 65 yr) patients with insulin-requiring diabetes mellitus (n = 57) was undertaken to audit safety of self-management. Levels of knowledge and management skills of hypoglycaemia, hyperglycaemia, and foot care were determined. The prevalence of hypoglycaemia, visual impairment, and at-risk feet and the ability to perform practical procedures (insulin injection and self-monitoring) were assessed. Drawing up insulin and self-injection was correct in 84% and 76% of patients, but 53% of self-monitored urine or blood tests were performed incorrectly. Twenty-six per cent experienced hypoglycaemia at least monthly and 25% had been seen at the hospital with hypoglycaemia in the last year. Eighteen per cent did not know what action to take with hypoglycaemia. Forty-six per cent did not know any hyperglycaemic symptoms or signs. Prompted with symptoms, 35% still did not know what to do and 21% would take inappropriate action when self-monitored tests read high. Fifty-one per cent had impaired vision, 61% peripheral neuropathy and 24% peripheral vascular disease, with the result that 78% had at-risk feet. Fifteen percent inspected or washed their feet infrequently, 40% walked barefoot occasionally, and 47% would take potentially dangerous action in the event of foot injury. This study demonstrates serious deficiencies in the basic education and management skills in our elderly insulin-requiring diabetic population that could result in morbidity and mortality. Greater effort and vigilance by health care professionals must be directed towards this group.

The acute and chronic complications of diabetes account for the morbidity and mortality associated with this disease. Acute complications include diabetic ketoacidosis, hyperosmolar hyperglycemic nonketotic coma, and hypoglycemia. Chronic hyperglycemia is central to the pathophysiology of chronic complications such as cardiovascular and peripheral vascular disease, retinopathy, nephropathy, and neuropathy. Pathophysiology and assessment of, and interventions for these complications are discussed.

Results of 127 iliac and femoropopliteal transluminal angioplasties in 97 diabetic patients are presented. Patients who had undergone iliac (n = 70), femoral (n = 41), and popliteal (n = 16) angioplasties for stenoses up to 15 cm long were followed up for 6-60 months. In diabetic patients presenting with only claudication or adequate runoff, the 5-year iliac patency rate was 76% and the femoral patency rate was 60%; these results were comparable with those found in non-diabetic patients. For limb salvage, 3-year patency rates were 66% for iliac, 37% for femoral, and 37% for popliteal angioplasties, and 5-year patency rates were 29% for iliac, 7% for femoral, and 0% for popliteal angioplasties. Our findings suggest that the overall decreased PTA success rates typically associated with diabetes are due to the larger percentage of these patients who present with symptoms of severe peripheral vascular disease and not to the presence of diabetes per se.
