摘要:

AbstractThe Fairfield Hospital experience with isolation of HIV from peripheral blood leucocytes, cerebrospinal fluid and semen is described. To date HIV has been isolated from single specimens of blood from 45% of patients with AIDS, 35% of patients with lymphadenopathy syndrome AIDS‐related complex or ARC and 14% of asymptomatic antibody positive individuals. HIV was recovered from peripheral blood leucocytes in the presence of phytohemagglutinin and interleukin‐2. The presence of virus in the supernatant fluid was detected using reverse transcriptase and immunofluorescence assays. Supernatants with borderline activity were confirmed by infection of a continuous cell line. (Aust NZ J Med 1987; 17: 461

摘要:

AbstractIt is important to identify diabetic patients in a coronary care population because they have a higher risk of suffering congestive heart failure, dysrhythmias and death following myocardial infarction. In order to determine the most efficient screening method for diabetes, we compared fructosamine and glucose measurements on admission blood specimens from 256 consecutive patients. Of 15 (5.9%) known diabetic patients, 12 had glucose results>7.8 mmol/l and nine had fructosamine levels>2.87 mmol/l. However, elevated glucose results were also found in a high proportion (49.2%) of patients with no previous history of diabetes. We performed glucose tolerance tests in 107 patients after discharge to determine the frequency of false‐positive observations. Fructosamine yielded five (4.6%) false‐positive results, whereas plasma glucose yielded 47 (43.9%) false‐positive observations. We conclude that serum fructosamine provides a more specific screening method for diabetes in this population because the results are unaffected by stress hyperglycemia. (Aust NZ J Med 1987; 17: 467

摘要:

AbstractIn 105 patient pairs, matched for sex, aged within a ten‐year range and with closely similar coronary disease, the sensitivity and specificity of treadmill testing using the Bruce Protocol was compared to cycle ergometry using the 100 kpm/min (16 W/min) increment protocol, and found to be similar. The parameters of use were ST segment depression (sensitivity of 52% for treadmill and 61% for cycle), test angina (65% and 61%), significant work impairment (66% and 68%) and impaired blood pressure response (31% and 20%). The sensitivity was increased (treadmill to 84%, cycle to 89%) if the four parameters were grouped, and abnormality in any one of them was regarded as a positive test.The equivalent severity of coronary disease resulted in more severe work impairment on the cycle than on the treadmill. The mean work level of the treadmill group was 80%, and of the cycle group, 61% of their respective, nomographically predicted, normal values. The difference was similar for the zero. sinale and multivessel disease aroum. This difference should be recognised when comparing the two techniques. (xust NZ J Med 1987; 17: 472–4

摘要:

AbstractTc‐99m is a preferred agent for nuclear imaging. Tc‐99m tertiary butyl isonitrile (Tc‐99m‐TBI) is the first of a family of lipophilic cations which allow effective imaging of the human myocardium. Twenty‐one patients scheduled for coronary angiography for the investigation of their chest pain were studied after injections of this tracer given during exercise, and on a separate visit, at rest. Despite high uptake in the liver and transiently in the lungs, high quality gated images were obtained allowing the assessment of both myocardial uptake and wall motion. The findings corresponded closely with angiographic and ventriculographic assessment of coronary artery disease and myocardial infarction. Redistribution of Tc‐99m‐TBI was shown to occur in ischemic myocardium analogous to that occurring with thallium‐201 (TI‐201). Similar agents with more favourable properties may well replace TI‐201 as the myocardial imaging agent of choice

摘要:

AbstractIn a survey of 530 patients, aged 75 years and older, who were admitted to a general teaching hospital in Christchurch, 60 (11.3%) were known diabetics. One hundred and seventy‐six other patients (33.2%) had a last measured laboratory blood glucose level of>7.8 mmol/l, of whom 27 people (5.1% of all patients) had significant hyperglycemia (over 11 mmol/l).The Geriatric Assessment and Rehabilitation Unit (ARU) and acute general medical wards of the Princess Margaret Hospital made little use of the specialised Diabetes Services for help in managing known or newly diagnosed diabetics. The mean in‐hospital laboratory blood glucose value for all diabetics was an unphysiological value of 12.2 mmol/l, compared with a community mean of 4.9 mmol/l and hyperglycemia persisted after resolution of acute medical problems. ARU diabetic patients had significantly lower blood glucose values than those achieved by physicians in acute medical wards. Prescribed medications such as steroids or diuretics contributing to insulin resistance were rarely modified.It is concluded that 16.4% of elderly patients had significant hyperglycemia or poorly managed diabetes mellitus, and that both general and geriatric physicians underestimated both the severity and consequences of elevated blood sugars in older patients in a regional New Zealand community with a ‘high’ diabetes profile.
