Randomized Controlled Trial Comparative Study Clinical Trial
Is a random urinary albumin concentration a useful screening test in insulin-treated diabetic patients?
The debate continues on how to screen for microalbuminuria in clinical practice in patients with insulin-dependent diabetes mellitus. Our study assesses the value of a spot morning urine specimen obtained at a clinic visit. In 1984, as part of a randomised survey of our diabetes clinic, 43 of 249 patients with insulin treated diabetes mellitus, were found to have microalbuminuria (urinary albumin concentration 35-300 ug ml-1) on a spot morning urine sample. ⋯ In the group with microalbuminuria, 10 of 27 still had incipient nephropathy while five had progressed to nephropathy. In the group without microalbuminuria only three of 33 patients had progressed to microalbuminuria while none had progressed to nephropathy. In conclusion a spot morning urine sample is a useful screening test to identify patients at risk of progression to nephropathy.

A 61 year old female patient presented with metastatic bone pain three years post mastectomy. Standard oral analgesics and epidural morphine were ineffective in achieving pain control. Her pain was eventually controlled with morphine sulphate 48 mg daily via a self administered intrathecal pump. These devices are being used with increasing frequency and this case report highlights some of the problems encountered in this patient's management.

Fifteen patients with intractable pain received intrathecal morphine delivered via a programmable (Medtronic) device. In twelve patients the pain was due to cancer and three patients had pain of non malignant origin. All of the patients reported excellent or good relief. ⋯ One patient with pain of non malignant origin developed serious complications which required the removal of the infusion device. The results of this study show that chronic intrathecal infusion of morphine is superior to conventional forms of analgesia in patients with intractable pain of malignant origin. We would advise that it should remain a therapy of last resort in patients with intractable non malignant pain as the long term side effects are still unknown and the potential for serious side effects still exists.

Recommendations exist that fasting plasma glucose (FPG) levels can be substituted for glycosylated haemoglobin A1 (HbA1) in Type II diabetic subjects (DM II), which have potential important financial implications. The present study was designed to expand this examination and to include Type I DM (DMI) patients and random blood glucose (RBG) values. Data were obtained from 234 DM II and 104 DM I patients, over 3 years. ⋯ Correlation of HbA1 with RBG and 2 h post prandial glucose measurements yielded r values of 0.59 and 0.51 respectively, p < 0.001. In DM I, similar correlations gave r values ranging between 0.27 and 0.38, p < 0.01-0.001. Thus while significant correlations exist between HbA1 and FPG and RBG measurements in both DM I and DM II, clinically applicable information on long-term diabetic control can only be achieved from glucose measurements in DM II but the correlation is not sufficiently tight to recommend substitution of plasma glucose for HbA1 determinations, despite the cost advantages.

Clinical and angiographic findings are reported in a consecutive series of nineteen patients with post infarction ventricular septal defect (PIVSD). In all patients PIVSD complicated a first myocardial infarct and none had a history of angina pectoris prior to presentation. In over 50% of the patients PIVSD occurred within three days of infarction. ⋯ The mean left ventricular ejection fraction was 27%. Contrast left ventriculography localised the defect in all patients. Although a comprehensive cardiac ultrasound examination will generally confirm the diagnosis of PIVSD, preoperative coronary angiography is essential for the selection of those patients most likely to benefit from concomitant coronary artery bypass grafting at the time of surgical repair of the interventricular septum.
