Study objective-The aim was to establish leg ulcer point prevalence, basal patient characteristics, and level of caretaking.Design-The study was a postal cross sectional survey. The Participants-827 individual patients were found with active leg ulcers, 526 women and 301 men.Measurements and main results-Age adjusted sex ratio of ulcer patients was 1:1-4 (M:F). The median age was 78 years for women and 76 for men; 700 patients (85%) were older than 64 years. The point prevalence for active leg ulcers was 3-0I1000 total population. District nurses provided care for 680 patients (82%), 106 (13%) were in hospital care, and 41 (5%) were managed by outpatient departments.Conclusions-There has been an underestimation of the leg ulcer problem among elderly patients, especially men. With an expected increasing number of elderly people it is important that this problem is recognised and measures taken to improve the primary care of these patients.
Ninety-three patients with treatment-resistant venous ulcers were included in a multicentre randomized trial to compare cadexomer iodine and the standard treatment used in each centre combined with compression bandages, in healing venous ulcers. The mean duration of ulcers before the trial was more than 2 years. With standard treatment the mean ulcer size increased slightly during the 6-week trial whereas with cadexomer iodine the ulcer size was significantly reduced. Cadexomer iodine was more effective than standard treatment for reduction of pain, removal of pus and debris, removal of exudate, stimulation of granulation and reduction of surrounding erythema. Bacterial infection of ulcers increased or did not change during treatment with the standard therapy whereas cadexomer iodine significantly reduced infection with Staphylococcus aureus, Pseudomonas aeruginosa and other pathogenic organisms. A correlation was seen between the time taken to reduce or eliminate infection with Staphylococcus aureus and rate of ulcer healing. Four patients complained of transient pain in the ulcer after application of the cadexomer iodine. It is concluded that cadexomer iodine increased the rate of healing of infected chronic venous ulcers.
In a randomized, prospective, double-blind multicentre trial, the effect of conventional low-dose heparin 5000 units twice daily, was compared with that of a low molecular weight heparin fragment (4000-5000) 5000 anti-factor Xa units once daily. Four hundred and thirty-two patients fulfilled the inclusion criteria and were analysed for development of deep vein thrombosis (125I-labelled fibrinogen test) and haemorrhagic complications. Thrombosis occurred in a 4.3 per cent of patients in the low-dose heparin group and in 6.4 per cent of patients in the heparin fragment group, a difference which is not significant. There was a significant delay in the onset of thrombosis in the heparin fragment group. Mortality did not differ between the groups, nor did peroperative blood loss or transfusion requirements or infectious complications. Haemorrhagic complications occurred significantly more often in the fragment group (11.6 per cent) than in the conventional heparin group (4.6 per cent). Patients in the heparin fragment group experienced local pain following the subcutaneous injection significantly less often.
A prospective randomized double-blind trial was performed comparing conventional low-dose heparin with a low molecular weight heparin fragment for thromboprophylaxis in elective general abdominal surgical patients. The first dose of the heparin fragment was given the evening before surgery, and further doses were given thereafter every evening. There were 1002 analysable patients, 826 having received correct prophylaxis. Of these 1002 patients, 64 per cent were operated on for malignant disease. A total of 20 patients died, 10 in each group. The frequency of deep vein thrombosis was significantly reduced among patients with correct prophylaxis with the heparin fragment (9.2-5.0 per cent, P = 0.02) [corrected]. The frequency of bleeding was 6.7 per cent among the heparin fragment patients and 2.7 per cent among the patients given conventional heparin (P = 0.01), but all bleeds were of minor degree and there was no difference in the reoperation rate for bleeding, or in the transfusion requirements. Local pain at the injection site was reported significantly less often among patients given the heparin fragment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
