Leg Ulceration (leg + ulceration)
Selected AbstractsFoetal haemoglobin in homozygous sickle cell disease: a study of patients with low HBF levels*INTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 5 2001A. Donaldson High foetal haemoglobin (HbF) levels are believed to ameliorate the manifestations of homozygous sickle cell (SS) disease. The corollary implies that patients with low HbF levels should have more severe clinical courses. We investigated this in a retrospective study of 50 Jamaican patients with steady-state HbF levels below 1% compared with a control group (A) of 54 subjects with steady-state HbF levels between 2.5 and 3.4% (around the 25th centile for our population), and a second control group (B) of 60 patients with steady-state HbF levels between 4.6 and 5.2% (around the 50th centile). Comparisons across the groups indicated significantly fewer females in the study group (16, 50 and 57%, respectively). Examination for haematological trends across the groups showed positive linear trends for haemoglobin (Hb) (P=0.004), packed cell volume (PCV) (P=0.01), mean cell volume (MCV) (P=< 0.001), mean cell haemoglobin (MCH) (P=< 0.001) and a negative trend for haemoglobin A2 (P=0.03). Clinically, there were no differences in the incidence of painful crises, abdominal crises and the acute chest syndrome, but leg ulcers were significantly less frequent in the study group (P=0.04). Therefore low HbF levels do not appear to increase the clinical severity of SS disease and may be protective against leg ulceration. [source] A systematic review of health-related quality of life instruments used for people with venous ulcers: an assessment of their suitability and psychometric propertiesJOURNAL OF CLINICAL NURSING, Issue 19-20 2010Simon J Palfreyman Aims and objectives., To review the quality of life questionnaires used to measure the impact of venous ulceration and to evaluate their psychometric properties. Background., Venous leg ulcers have a negative impact on quality of life. Health-related quality of life can be measured using structured questionnaires. Nurses are the primary care providers for patients with venous ulceration and are ideally placed to assess and develop these types of questionnaires. There may also be an opportunity to use such quality of life instruments to measure the impact of nursing interventions in other areas where nurses are the key care providers. Design., Systematic review. Method., Studies were sought that used quality of life instruments to evaluate the impact of venous ulceration. Fourteen electronic bibliographical databases and 11 Internet-based health services research related resources were searched. In addition, grey literature was sought and the reference lists of relevant articles checked. Data were extracted regarding the type of instrument used, sample, number of items and domains and psychometric performance of the instrument. Results., The initial search identified a total of 338 potential citations. After review, a total of 31 studies were included: 17 used generic and 14 used disease-specific instruments. Five different types of generic and seven disease-specific instruments were identified. There was significant heterogeneity between the studies in terms of study design, aetiology of ulceration and times of assessment. The disease-specific instruments showed limitations in relation to their applicability to venous ulcer patients because of flaws in design or validation. Conclusions., The literature on quality of life related to venous ulceration failed to sufficiently distinguish between those with different causes of leg ulceration. There appeared to be problems with the ability of current quality of life instruments to detect changes in quality of life related to ulcer healing. Relevance to clinical practice., There appears to be an opportunity for nurses to develop a health-related quality of life health-related quality of life instruments to evaluate their impact on patient outcomes. Such instruments could potentially allow nursing interventions to be assessed more effectively than the recently proposed nursing metrics. [source] Functional ability in female leg ulcer patients , a challenge for physiotherapyPHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 4 2006Kirsti Skavberg Roaldsen Abstract Background and Purpose.,Venous leg ulceration represents a global health problem affecting predominantly elderly women. Traditionally, functional problems in this group of patients have attracted modest attention from wound care providers and physiotherapists. The aim of the present study was to describe and quantify disease consequences in female leg ulcer patients as a background for future physiotherapy interventions, using the nomenclature of the WHO International Classification of Functioning, Disability and Health (ICF).,Method.,A prospective study was conducted in 34 women aged 60,85 years with current or previous venous leg ulcer as compared to 27 age-matched non-ulcer subjects. The outcome variables were pain, ankle range of motion, walking speed, walking endurance, self-perceived exertion, mobility, activities of daily living (ADL), physical activity, general health, life satisfaction and use of walking aids and community services. Established instruments were utilized and categorized within ICF domains to provide a conceptual framework and basis for physiotherapeutic research.,Results.,Leg ulcer patients showed significantly reduced values of ankle range of motion, walking speed and endurance, self-perceived exertion, mobility, ADL and physical activity level as compared to control subjects. Patients suffering from active ulceration were more negatively affected, and more of them had pain than post-ulcer fellows. By contrast, general health and life satisfaction were similarly rated by the two study groups.,Conclusions.,Elderly females in our study with chronic leg ulcer of venous aetiology had significant mobility impairments, but the reasons and consequences of these impairments remain to be elucidated. The potential of preventive measures and physical rehabilitation to aid functioning and prospects of leg ulcer repair need to be investigated in future studies.

Humphreys Background: The aim was to assess healing in patients with mixed arterial and venous leg ulcers after protocol-driven treatment in a specialist leg ulcer clinic. Methods: The study included consecutive patients referred with leg ulceration and venous reflux over 6 years. Legs without arterial disease (ankle : brachial pressure index (ABPI) above 0·85) were treated with multilayer compression bandaging and patients with severe disease (ABPI 0·5 or less) were considered for immediate revascularization. Those with moderate arterial compromise (ABPI above 0·5 up to 0·85) were initially managed with supervised modified compression and considered for revascularization if their ulcer did not heal. Healing rates were determined using life-table analysis. Results: Of 2011 ulcerated legs, 1416 (70·4 per cent) had venous reflux. Of these 1416, 193 (13·6 per cent) had moderate and 31 (2·2 per cent) had severe arterial disease. Healing rates by 36 weeks were 87, 68 and 53 per cent for legs with insignificant, moderate and severe arterial disease respectively (P < 0·001). Seventeen legs with moderate and 15 with severe arterial disease were revascularized. Of these, ulcers healed in four legs with moderate and seven with severe disease within 36 weeks of revascularization (P = 0·270). Combined 30-day mortality for revascularization was 6·5 per cent. Conclusion: A protocol including supervised modified compression and selective revascularization achieved good healing rates for mixed arterial and venous leg ulceration.
