A disposable skin stapler (Proximate; Ethicon) was compared with conventional nylon sutures in respect of time taken for wound closure, cosmetic result and ease of application and removal. It was found that a time saving of 80% is possible with the stapling device, and that the cosmetic result with staples is as good as if not better than that with nylon(More)
This prospective study was undertaken to evaluate the role of duplex Doppler (DD) scanning in the diagnosis of masses of suspected vascular origin at the carotid bifurcation. We also assessed the different DD signs of carotid body tumors, especially the difference in resistance index (RI) in the external carotid artery on the side of the tumor. Over a(More)
Although elective abdominal aortic aneurysm (AAA) repair can be done with a less than 5% mortality rate, ruptured AAAs have a 32-85% mortality rate. The aims of this study were: (i) to identify prognostic factors affecting mortality; (ii) to identify and assess the impact of postoperative complications on mortality; and (iii) to try to identify a subgroup(More)
A prospective study comparing the accuracy of B-mode ultrasound with evaluation of gross appearance in detecting plaque hemorrhage and ulceration is reported. Ultrasonography was performed on 78 vessels in 66 patients undergoing carotid endarterectomy. Carotid bifurcation atheroma were classified ultrasonographically as smooth, irregular, or ulcerated.(More)
A multidisciplinary group was formed to advise on strategy and to co-ordinate the management of a family at risk for the multiple endocrine neoplasia type 2A (MEN 2A) syndrome. A proposed strategy is outlined in which DNA analysis and provocative calcitonin testing is central.
A South African family, at risk for the multiple endocrine neoplasia type 2A (MEN 2A) syndrome, was identified. The Bloemfontein MEN Study Group was founded, inter alia, to study the effects of early detection of medullary carcinoma of the thyroid (MTC) and treatment by total thyroidectomy in children and young adults with MEN 2A. Genotypes were identified(More)
The incidence of false aneurysms, anastomotic stenoses, and ureteric obstruction is reported to be low in patients who have undergone aortic surgery. The use of intravenous peripheral digital subtraction angiography (IVDSA) with completion excretory urography (CEU) may provide a more sensitive means of long-term detection of these complications. The aim of(More)
We report our experience with a provocative test of calcitonin (CT) release using a combined stimulus of intravenous 10% CaCl2 solution and pentagastrin on 34 normal adults (15 females: age 41 +/- 12.3 years and range 22-65 years; and 19 males: age 43 +/- 9.1 years and range 23-60 years) and in 44 family members of three proven multiple endocrine neoplasia(More)
