Diagnosis Of Leg Ulcers

In the United States, leg ulcers present a significant clinical problem, occurring at a rate of approximately 600,000 new cases per year. (1) The most common types are venous, arterial, and neuropathic ulcers. Venous hypertension is the primary culprit in venous ulcerations. Peripheral vascular disease due to atherosclerosis with microvascular or macrovascular changes leads to ischemic ulcers. Sensory impairment with loss of protective sensation in the foot and repetitive trauma lead to neuropathic ulcers. Unusual causes of leg ulcers must be considered in the differential diagnosis. To arrive at the diagnosis, the clinician must perform a thorough history and physical examination, and order relevant investigative studies. Good management of chronic leg ulcers depends on correction of identified underlying conditions, long-term multidisciplinary care effort, and integrating traditional and new wound-healing technologies. Most patients with chronic leg ulcers benefit from the use of compression bandaging at a level appropriate to their vascular status. Venous ulcers must be managed with an arsenal of strategies to control venous insufficiency, heal the wound, and prevent recurrence. Surgery with revascularization remains the treatment of choice for chronic ischemic leg ulcers. In the absence of vascular compromise, up to 90 percent of neuropathic ulcers will heal with proper ulcer debridement, treatment of infection, saline wet-to-dry dressings, and relief of weight from the ulcerated area. The available armamentarium for wound care includes over 2000 wound dressing products and elastic compression wraps. Chronic leg ulcer treatment options have been expanded by alternatives available to treating these wounds. These alternatives include hyperbaric oxygen therapy, bioengineered skin substitutes, recombinant platelet-derived growth factors and vacuum assisted wound closure. Patients with large leg ulcers may benefit from skin grafting. Other patients may benefit from ligation and stripping of superficial veins or subfascial interruption of perforating veins.

Chronic leg ulceration is a very common clinical problem in the elderly. Good management depends entirely on making an accurate diagnosis, and planning treatment after considering all aspects of patient well-being. All elderly patients with leg ulcers benefit from an assessment of their vascular status, since the effects of gravity influence treatment and healing irrespective of the diagnosis. The most common causes of ulceration are venous and arterial disease. Diabetes mellitus, pressure, vasculitis, metabolic abnormalities and skin cancer are all unusual causes of leg ulceration, but must be considered in the differential diagnosis. Almost all patients with ulcerated legs benefit from the use of compression bandaging at a level appropriate to their vascular status. In patients with venous ulcers, this can be achieved with a number of bandaging techniques; however, multilayer bandaging appears to be the most cost-effective means available, particularly when combined with community-based leg ulcer clinics. The effects of oral drug therapy for venous and arterial disease have been disappointing. Local dressings are important in ulcers that are not suitable for compression therapy. The choice of dressing depends on the nature of the ulcer and the tolerability of the dressing for the patient.

Chronic leg ulcers are a major cause of mortality and morbidity. The efficacy of hyperbaric oxygen treatment is being evaluated in the management of nonhealing leg ulcers to improve skin graft survival. Twenty-seven patients with 36 chronic leg ulcers were examined. Each wound received 12 preoperative hyperbaric oxygen treatments, split-thickness skin grafting, followed by 12 postoperative hyperbaric oxygen treatments. Wound transcutaneous oxygen tension measurements (TCOM) were taken. The graft take was evaluated. At 18 months follow-up, 18 skin grafts (50%) showed complete take, 15 (41.7%) demonstrated partial take, and 3 (8.3%) failed. Hyperbaric oxygen treatment is an effective adjunct in the management of chronic leg ulcers, and its use resulted in increased graft take and survival.

Chronic venous leg ulcer (CVLU) is a common and refractory complication of chronic venous diseases, and is clinically characterized by chronic leg ulcers and pain. Matrix metalloproteinases (MMPs) are a kind of highly conservative and zinc-dependent endopeptidases, and can be divided into 6 types according to their substrates and structures. Among the 6 types, collagenases, gelatinases and stromelysins play a key role in the occurrence and development of CVLU. Moreover, the up-regulation of MMP-1,-2,-3,-8 and ratio of MMP-2 to tissue inhibitor of metalloproteinase-2 (TIMP-2) is associated with delayed ulcer healing, whereas the up-regulation of MMP-7,-10,-13 and TIMP-1,-2 facilitates ulcer healing. However, roles of MMP-9 and -12 in venous ulcers are still unclear and need further study. According to functional characteristics of some MMPs, intervention of their composition and functions may provide new therapeutic targets for the treatment of CVLU.

The definition of the venous ulcer

Background and Objectives: Any ongoing injury which shows no inclination to heal following 3 months of suitable therapy or in a time of a year the injury is not completely healed comprise chronic leg ulcers. Venous, Arterial and Neuropathic ulcers are the major types of chronic leg ulcers and factors like smoking, obesity, Diabetes mellitus & increased age boost up the incidence of ulceration. Expanded rate of leg ulcers, monetary weight, and recurrence of the ulcer which increases the degree of Homeopathy. The present review comprises the literature on the Homoeopathic approach in managing the various chronic leg ulcers. Materials and Methods: A literature search was conducted in databases like PubMed, Google Scholar, Wiley online library, Springer, Scopus, AYUSH portal, to collect all relevant research studies, review article, case series & case reports, published from 1990 until July 2020. This research was categorised by study type and assessed according to study design with their clinical outcomes.Results: Out of these 5 studies, 3 are case studies & one is a prospective observational study and one is a randomized clinical trial and it shows that chronic leg ulcers have marked improvement by the use of Homoeopathic medicine both internally and externally.Conclusion: Homoeopathy is effective in the management of chronic leg ulcers mainly diabetic foot ulcers and varicose ulcers. A combination of both internal and external medicines also showed excellent results in treating this illness. There is only limited evidence available to show the effectiveness of Homoeopathy and more studies needed for the same.

Loss of membrane complement regulators accompanied by complement activation is suggested to be involved in the pathophysiological processes leading to tissue damage in myocardial ischaemia. In the present study we have investigated whether the same phenomenon may occur in ischaemic and/or venous hypertension leg ulcers. The deposition of complement, plasma complement regulators and expression of membrane regulators were detected by immunohistochemical methods, including immunofluorescence with antibodies against C3d, the terminal complement complex (TCC), vitronectin, clusterin, decay-accelerating factor (CD55) and protectin (CD59). Eleven frozen biopsies from ischaemic leg ulcers, 10 biopsies from venous hypertension leg ulcers, and 10 biopsies from normal skin were studied. In 9 of 11 ischaemic and in 5 of 10 venous hypertension leg ulcers, marked staining for TCC was found around the capillaries, most often at the ulcer margin. No TCC staining was found in normal skin. Staining for TCC was always accompanied by staining for clusterin and vitronectin and C3d. In normal skin, CD59 was found on the elastic fibers in the dermis, on the muscle coat, the Schwann sheath and acinar cells. Semiquantitative measurement of CD59 showed marked increased staining intensity in the endothelium in venous hypertension ulcers and diminished intensity in ischaemic ulcers compared to normal skin. No such difference could be observed for CD55. When TCC was positive in the capillary walls, weak or no staining for CD59 was found. A significantly higher ratio of TCC/CD59 was found in the ischaemic compared to venous ulcers (p = 0.018). This was due to a marked difference between the ulcer margins (p = 0.013). Localized areas in the venous ulcers had the same pattern as that seen in the ischaemic ulcers. Our results suggest that loss of CD59 may enhance deposition of TCC and that complement-dependent inflammation may be an important factor in the tissue-damaging processes seen in chronic leg ulcers.

Although many causes of leg ulceration have been reported over 70% are related to venous insufficiency associated with venous hypertension. Contact sensitivity (allergic contact dermatitis) is a frequent complication in patients with chronic venous leg ulcers affecting between 51–81% of patients. Complications associated with contact sensitivity in patients with non-healing leg ulcers are increased morbidity due to eczema and irritation which may result in delayed healing. This article reviews the frequency of contact sensitivity. Research has shown that lanolin and topical antibiotics, such as neomycin and framycetin, are the most common leg ulcer sensitizers and should be avoided in treatment. Creams have also been shown to contain sensitizers and therefore ointments should be used in preference to creams. The avoidance of allergens is important in the prevention of contact sensitivity and the promotion of ulcer healing.

Slough in chronic venous leg ulcers may be associated with delayed healing. The purpose of this study was to assess larval debridement in chronic venous leg ulcers and to assess subsequent effect on healing. All patients with chronic leg ulcers presenting to the leg ulcer service were evaluated for the study. Exclusion criteria were: ankle brachial pressure indices <0.85 or >1.25, no venous reflux on duplex and <20% of ulcer surface covered with slough. Participants were randomly allocated to either 4-layer compression bandaging alone or 4-layer compression bandaging + larvae. Surface areas of ulcer and slough were assessed on day 4; 4-layer compression bandaging was then continued and ulcer size was measured every 2 weeks for up to 12 weeks. A total of 601 patients with chronic leg ulcers were screened between November 2008 and July 2012. Of these, 20 were randomised to 4-layer compression bandaging and 20 to 4-layer compression bandaging + larvae. Median (range) ulcer size was 10.8 (3-21.3) cm(2) and 8.1 (4.3-13.5) cm(2) in the 4-layer compression bandaging and 4-layer compression bandaging + larvae groups, respectively (Mann-Whitney U test, P = 0.184). On day 4, median reduction in slough area was 3.7 cm(2) in the 4-layer compression bandaging group (P < 0.05) and 4.2 cm(2) (P < 0.001) in the 4-layer compression bandaging + larvae group. Median percentage area reduction of slough was 50% in the 4-layer compression bandaging group and 84% in the 4-layer compression bandaging + larvae group (Mann-Whitney U test, P < 0.05). The 12-week healing rate was 73% and 68% in the 4-layer compression bandaging and 4-layer compression bandaging + larvae groups, respectively (Kaplan-Meier analysis, P = 0.664). Larval debridement therapy improves wound debridement in chronic venous leg ulcers treated with multilayer compression bandages. However, no subsequent improvement in ulcer healing was demonstrated.

Background: Accurate diagnosis is essential if patients with chronic leg ulceration are to receive optimal treatment. Multiple disciplinary approach is usually required for complete healing of chronic ulcers. Methods: A prospective study of seven months duration was conducted on 50 consecutively admitted cases of chronic leg and foot ulcers in age group of 5-80 years of both genders. A through detailed history and clinical examination was undertaken. Local Symptoms, trophic skin changes and venous insufficiency if any was recorded. Both general and specific treatments were provided. Results: Maximum cases were in the age group of 31-50 years, M: F ratio 1.9:1 and rural: urban ratio 2.57:1. Majority of patients were illiterate (76%), and were drawn from lower class of the society (56%). Majority of patients (54%) were smokers, tobacco chewers or alcoholics. Site of ulcer was foot 52% followed by leg 18%, ulcer origin was traumatic in 72% of cases and ischaemic ulcers were minimum 2%. Symptom wise wound, pain and discharge 32% followed by wound and discharge 26% were noted. 66% of ulcers were secondarily infected and maximum number of cases 68% stayed in hospital for about 2 weeks. In 68% cases healing was complete in about 3 months. Conclusions: A correct diagnosis, multidisciplinary approach, optimal treatment and assessment of vascular status can facilitate healing of chronic leg ulcers in nondiabetic cases.

The possible impact of nutritional status on healing and course of disease in patients with chronic wounds is widely suggested, however, most data are based on small groups of patients with no control group and minor afflictions. Clear diagnostic strategies are missing. To analyse in detail the nutritional status of chronic wound patients relative to healthy controls based on a large patient population. We screened a group of 50 patients for their nutritional status based on body mass index (BMI), the Mini-Nutritional Assessment (MNA), and Nutritional Risk Screening (NRS), as well as additional laboratory investigations. Twenty-five patients suffered from chronic venous leg ulcers and were compared with a matching control group of 25 patients with acute surgical wounds. Patients with chronic venous leg ulcers showed significantly higher BMI, hyperhomocysteinaemia, and higher levels of serum copper but significantly lower levels of vitamin B6, B9 and C, as well as a significantly lower level of zinc. Vitamin D deficiency was present in both groups, however, severe vitamin D deficiency was present only in the leg ulcer group. Mobility was significantly reduced in patients with leg ulcers. Ulcer patients are often obese but suffer from qualitative malnutrition, including a lack of vitamin D, which might be explained by reduced mobility and being housebound. Hypoalbuminaemia, as a sign of protein deficiency, was observed significantly more often in patients with chronic leg ulcers, irrespective of wound area or wound duration.

Chronic leg ulceration may often be accompanied and exacerbated by the presence of oedema, a common health problem that can cause ulceration, which if left untreated can require amputation. Current clinical consensus indicates compression as the recommended treatment for oedema. While cardiac function is also known to influence oedema, it is rarely considered a parameter of wound management. This article presents a case study of a patient with oedema and ulceration, who avoided a scheduled amputation when lesions healed following the optimisation of cardiac function. The patient had right-sided heart failure with preserved ejection fraction. After fluid drainage, the ulcers began to heal. The case raises the question of cardiac optimisation of leg ulcer patients. This case highlights the potential role of cardiac management in leg ulcer treatment and raises an important question: should cardiac optimisation be a greater consideration in the care of patients with leg ulcers? The prevailing emphasis on compression therapy may benefit from reassessment, with particular attention to the role of cardiac function in wound healing.
