    Elderly people gain enjoyment in their remaining years from eating, speaking and tasting things, and they find that the oral function is necessary to arouse in them a desire to work for society, in addition to looking after their own health, they find that over function is important. Recently, more attention has come to be paid to one's extenal appearance. Even if functione is impaired, appearance has a strong influence on the feeling of leading a worth-while life. Though increasing age brings a steady loss of teeth, it is unlikely that physiological change resulting from tooth decay and disease are the cause of tooth loss. Degradation of the hard tissue caused by decay is unavoidable. Unless the decayed area is removed and the teeth are repaired with artificial materials, the function of the affected tooth is permanently lost. Moreover, as decay progresses and periodontal disease worsens the state of a given area, extraction becomes necessary. This is the process by which teeth are lost. However, even if teeth are lost, masticatory function may be restored through the use of dentures. Recently, we carried out a survey which showed that a group of elderly people with good masticatory functions were more healthy and lived longer than a group of elderly people with reduced physical functions (weight, grasping strength, balance, bone salt volume) and poor masticatory function.

    We used ultrasonography to assess the accumulation of visceral fat and its relation to known risk factors for atherosclerotic disease, and examined its relation with atherotic changes in the common carotid artery. The subjects were 315 consecutive inpatients (173 men, 142 women; mean age, 68.3 years) hospitalized during a 21-month period. Those with a history of epigastric surgery or nutrition disorders that might affect fat thickness were excluded. A 7.5-MHz transducer was used to evaluate the maximum thickness of preperitoneal fat (Pmax) at the anterior surface of the liver, and the minimum thickness of subcutaneous fat (Smin) of the abdomen. The fat/height ratio was calculated. Age, gender, smoking status, blood pressure, total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol, atherogenic index ((total cholesterol-HDL-cholesterol)/HDL-cholesterol), blood sugar, serum insulin, and uric acid were examined as confounders. Pmax/height was found to be related to systolic blood pressure, diastolic blood pressure, total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol and atherogenic index, and was positively associated with the thickness of the common carotid arterial wall. Pmax/height may be a useful means to evaluate known risk factors for aherosclerotic disease.

    We reviewed MRI findings in a series of 211 patients with cerebral infarction. A high signal in the basis pontis bilaterally in T2 weighted images (Central Pontine Hyperintensity, CPH), with almost-normal T1 weighted images, was present in 29 cases (12.9%). CPH findings were present more frequently in elderly patients, and were significantly associated with a previous history of cerbrovascular accident, although not with other arteriosclerotic risk factors. In patients with CPH, periventricular hyperintensity was severe and the number of infarctions of the thalamus was higher. These results suggest that a) CPH may arise from ischemia in subcortical areas or in the territory of the vertebrobasilar system, and that b) chronic brain ischemia, which may be partially due to aging, may play a more important role in cerebral infarction than the usual arteriosclerotic risk factors.

    To assess the clinical significance of silent myocardial ischemia (SMI) in the elderly, 113 patients with stable angina who showed ischemic ST depressions during treadmill stress testing were studied by dipyrimadole thallium imaging and coronary arteriography. They were divided into two groups: 44 patients with silent ST depressions and 69 patients with painful ST depressions. The groups were compared for scintigraphic and coronary arteriographic features as well as prognosis.
    There was a significantly greater proportion of older patients (≥65 years) in the group with SMI (64%) than in the group with paiful ischemia (38%) (p<0.01), although there was no difference in the mean ages of the two groups. The prevalence of multivessel coronary stenosis was not significantly different between the two groups (45% in the SMI group and 61% in the group with painful ischemia). Treadmill stress testing showed no differences in exercise duration, maximal heart rate, maximal systolic blood pressure, or maximal ST depression between the two groups. Dipyrimadamole thalium imaging revealed similar results in the site of reversible defects (RD), i.e. 76% in the anterior area and 24% in the inferior area in patients with SMI, and 83% in the anterior area and 17% in the inferior area in patients with painful ischemia. However, the size of RD was significantly smaller in patients with SMI, i.e. 14.6±6.1 segments in patients with SMI and 18.7±8.3 segments in patients with painful ischemia (p<0.05). Although a significantly higher proportion of patients with painful ischemia (48%) underwent PTCA or CABG as their initial therapy as compared to those with SMI (16%), there was no significant difference in the cardiac event rate betwees the two groups initially treated medically.
    Among patients with stable angina, those with SMI may have a smaller amount of ischemic myocardium and may be older in a greater proportion than those with painful ischemia. Dipyrimadole thallium imaging is useful in the assessment of SMI in the enderly.

    The clinical significance of silent myocardial ischemia (SMI) in the elderly was assessed in 91 patients with Q wave infarction who showed ischemic ST depression during treadmill stress testing, as well as reversible defect (RD) during dipyridamole thallium imaging. They were divided into two groups (47 patients with silent ST depression and 44 patients with painful ST depression) and compared for scintigraphic and coronary arteriographic features, and prognosis.
    There was no significant difference in age, gender and site of infarction between the two groups. The prevalence of single and double vessel coronary stenosis was higher in patients with SMI (66%) than in those with painful ischemia (p<0.05). The results of treadmill stress testing showed a longer exercise duration (4.7±1.7 vs. 4.1±1.8min) and higher maximal heart rate (138±15/vs. 126±20/min) in patients with SMI than in those with painful ischemia (p<0.01). Dipyridamole thallium imaging revealed a larger infact (18.8±9.1 vs. 14.6±10.2 segments) in patients with SMI than in those with painful ischemia (p<0.05). The prevalence of RD in the area of infarction was also higher in patients with SMI (74%) than in those with painful ischemia (45%) (p<0.05). Although a higher proportion of the patients with painful ischemia (42%) underwent CABG or PTCA as their inital therapy, compared with those with SMI (25%) (ns), there was no difference in the cardiac event rate between the two groups who were initially treated medically.
    Dipyridamole thallium imaging is useful in the assessment of SMI in elderly patients with Q wave myocardial infarction. Those with SMI may have a larger infarct and a higher prevalance of ischemia localized within the infarction than those with painful ischemia.

    Senile dementia of Alzheimer's type (SDAT) is reported to be less frequent in patients with Diabetes Mellitus. However the, the number of elderly people in still increasing in Japan, an is the incidence of diabetes mellitus, especially in middleaged and elderly people. Thus, we can expect to encounter more elderly people with diabetes and SDAT.
    We encountered three patients with diabetes who were treated with insulin and in whom SDAT developed. In all three, control of blood glucose levels gradually worsened, despite increases in the dose of injected insulin. It was later found that they did not inject insulin properly because of SDAT. They lived alone and their dementia was not diagnosed before their admission to the hospital. In its early phase, SDAT can be difficult to diagnose, especially in patients who live alone. SDAT should be considered when the control of blood glucose levels for no apparent reason in elderly patients with diabetes.
