The ulcer destroys the deep fascia and may even expose the tendons at the base. The ischemic ulcers are extremely painful and the pain is excruciating irrespective of the size of the ulcer. The development of the arterial ulcers is more prolonged when compared to the venous ulcers. The appearance of ulcers having punched out edges with slough deployment on the floor of the wound resembling a gummatous ulcer points directly to a trophic ulcer. The most common forms of trophic ulcers seen are the bedsores. The heel and the ball of the foot and the back of the heel are the most common places where these types of ulcers occur. These ulcers start with callosity under which suppuration takes place, the pus comes out and the hole at the center forms the ulcer which gradually burrows through the muscles and the tendons to the bone. Tuberculous ulcer develop when cold abscess from bone and joint tuberculosis break out of the surface. Appearance of the ulcer is in the form of a thin edged one wound, which is reddish blue in colour and undermined. The base of the wound is coloured pale and there is slight induration at the base.

in patients was its use as a skin substitute for acute surgi- cal wounds (Eaglstein et al 1995) where it was found to produce better than expected healing in post-surgical sites (mainly used after cancer excisions). In a study comparing the skin substitute with secondary intention healing after Mohs micrographic or excisional surgery (Gohari et al 2002), the human skin substitute produced a more pliable, less vascular scar with a better cosmetic appearance than those healing by secondary intention. Living skin equivalent was also compared with autograft or polyurethane ﬁ lm in acute partial thickness donor site wounds and was found to have no toxic effect or clinically apparent rejection. It was found to decrease pain at the operative site compared with patients whose wounds were covered with polyurethane ﬁ lm (Muhart et al 1999). Apligraf has also been shown to expedite healing in excised (Waymack et al 2000) and full-thickness (Hayes et al 2001) burn wounds. Other reported successful uses include the following: the treatment of epidermolysis bullosa, showing that Apligraf treated areas healed faster than the areas treated with conventional therapy (Falabella et al 1999; Streit et al 2001); the treatment of chronic leg ulcers secondary to hydroxyurea that failed standard wound care (Flores et al 2000); chronic nonhealing pressure ulcers fail- ing standard therapy (Brem et al 2000); ulcerative sarcoid- osis that was unresponsive to steroid treatment (Falabella et al 2000); traumatic avulsion wounds in patients with age or steroid related dermal atrophy (Maier et al 2002); severe eroded and ulcerated actinic purpura (Banta and Kirsner 2002); bullous morphea (where a decrease in surrounding ﬁ brosis was also appreciated) (Martin and Kirsner 2003); and in the repair of cicatricial ectropion (Culican and Custer 2002), among others.
Material and methods. During a 3-year period, 284 digital computer planimetry measurements were gathered from 142 patients treated for leg ulcers caused by chronic venous insufficiency and ulcers from diabetic foot syndrome at HBOT Unit of the Dr Stanisław Sakiel Centre for Burns Treatment in Siemianowice Śląskie (Poland). Each patient took 30 HBOT sessions using a Haux multiplace HBO chamber at a pressure of 2.5 atmospheres absolute (ATA). The results of the treatment were monitored using thermovision and computer- assisted planimetry measurements performed before and after HBOT.
This article focuses on the role of footwear, bandaging and hosiery in the care of two of the most common complex, chronic wounds in the UK, leg ulcers and foot ulcers. A multi-service, cross-sectional survey undertaken across a city in England during two weeks in spring of 2011 produced a point prevalence estimate of leg ulcers of 0.44 per 1000, and of foot ulcers of 0.22 per 1000. 5 The mean age of those with leg ulcers was 76.46 years and the mean age of those with foot ulcers was 74.78 years. These wounds are closely associated with underlying conditions and co-morbidities which become more prevalent in older age and are a common, serious and costly global health issue. 6 7 8 Leg ulcers are mainly due to venous and/or arterial disease and many, but not all, foot ulcers are caused by vascular and neurological

analysing data so that preliminary analytical findings shaped subsequent sampling choices. A sampling frame was drawn up by the researcher with National Health Service (NHS) clinician partners based on discussions about the profiles of patients using the service. The researcher had no access to patients’ medical records. This study draws on material from the whole sample of 19 interviews with people who had lower limb ulcers (eight of whom had venous leg ulcers, six of whom had leg ulcers due to injecting drug use and five of whom had foot ulcers as a result of diabetes). Hosiery, bandaging and footwear interventions form part of the treatment landscape for these participants. At the time of the interviews, the four-layer compression bandage system (four-layer bandage) is regarded as the gold standard compression system to treat venous leg ulceration. 16 17 The bulky nature of this system has an impact on the footwear that can be worn while being treated; the patient’s own shoes may no longer fit, forcing changes in accustomed and preferred choices of both footwear and clothing. 18 Special footwear and casts to prevent weight bearing are also frequently used as a treatment for diabetic foot ulcers.

Aim: Diabetic foot ulcers are the most common cause of nontraumatic lower extremity amputations in the industrialized world. Tissue-engineering products offer a lower extremity salvage strategy when healing does not proceed according to the standard of care. New allogeneic sheets are available for the management of diabetic leg and foot ulcers. Methods: The endpoints of this case series study regard preliminary outcomes of the application of allogeneic keratinocytes composed of benzyl ester of hyaluronic acid to 16 diabetic foot and leg ulcers in 11 patients with type 2 diabetes mellitus. Results: Between 21 and 70 days after cellular therapy, 6 out of 16 lesions were completely healed, reducing the wound dimension by 70% and improving the wound bed score by 52%. Conclusion: The clinical results of the new allogeneic sheets indicate that allogeneic keratinocytes may represent an effective and safe therapy for diabetic foot and leg ulcers in the multidisciplinary approach to this diabetes-related complication.
(Callam MJ, et al)9. Arterial disease accounts for 5-10%; most of the others are due to neuropathy, usually diabetic or a combination of these diseases (Yound JR).10 Diabetic ulcers are common on the toe and the heel (Hansson Carita).11. Arterial insufficiency and / or diabetes may also be the causatives for ulcers below the line of the shoe. Ulcers at the ankles in the gaiter zone and venous ulcers are mostly caused by varicose veins (Hansson Carita). 11 Primary varicosity of the long saphenous system and / or short saphenous system is the causative factors for venous ulcerations (Hoare MC et al).13 The elevated ambulatory pressure in peripheral venous system in venous insufficiency manifests itself not only in form of disturbed microcirculation but also and particularly in microangiopathic changes. These include decrease in capillaries, glomerulus like changes and decrease in oxygen content. (Junger, M Stiens. A).14 It has been also noted that perivascular fibrin cuffs and skin hypoxia precede lipodermatosclerosis in limbs at increased risk of developing a venous ulcer (Stacey M. C., Burnand

Leg ulceration is typically precluded by minor trauma which leads to a small lesion that progressively enlarges . Significant pain is the rule. Bacterial colonization of ulcers is frequent, usually aerobic and polymicrobial with Staphylococcus aureus, Pseudomonas aeruginosa, and group A Streptococci most commonly isolated . One recent study found that 85% of patients had wound infections as a complication of ulceration, ranging from localized super-infection to recurrent cellulitis of the af- fected limb . Healing of ulcers is typically slow, re- sulting in hypopigmentation and chronic scarring. Pa- tients and healthcare workers alike should adjust their expectations appropriately.
painful than conventional dressing. Randomised controlled trial performed by Vuerstaek et al. evaluated outcome in leg ulcer patients receiving NPWT or conventional wound care techniques. The pain levels were found to be similar in both groups during the first 5 weeks of therapy, however, those who received NPWT reported significantly less pain after the fifth week. Authors suggest that although NPWT may be just as painful as other wound treatments, the pain may be less prolonged and only short-term. 14
trend in the reduction of sum of the area and volume of the ulcers is shown [Figures 2 and 3]. The mean percentage of improvement in area and volume of the ulcers was 91.7% (SD 18.4%) and 95% (SD 14%), respectively [Tables 3 and 4]. The confidence interval is been shown in Table 5. P value was set at less than 0.05 and hence the results were found to be significant. About 100% improvement in the area was seen in 25 (76%) of the ulcers and 100% improvement in volume was seen in 24 (73%) of the ulcers at the end of the 6th treatment [Figures 4 and 5]. There were no side effects noted. The before and after PRP therapy photographs are shown [Figures 6–11]. We also noted that there was a
Diabetic neuropathy affects the somatic motor, sensory and the autonomic nervous system. Sensory neuropathy can lead to extrinsic neuropathic foot ulceration following trauma. The initial trauma is often minor and may be due to ill-fitting footwear, thermal, foreign bodies in shoes, toenail cutting and thorn pricks. Sensory neuropathy paradoxically produces pain and paraesthesias.

The cost of treating an unhealed leg ulcer in the UK has been estimated to be around GBP 1300 per year at 2001 prices (Iglesias 2004). Another evaluation estimated the average cost of treating a venous leg ulcer (based on cost of dressings) as varying between EUR 814 and EUR 1994 in the UK and EUR 1332 and EUR 2585 in Sweden (price year 2002), with higher costs associated with larger and more chronic wounds (Ragnarson Tennvall 2005). This reflected findings from a more recent evaluation conducted in Hamburg, Germany, recruiting 502 community based adult patients with any type of leg ulcer. The total mean annual cost of illness for leg ulcers was estimated as EUR 9060 per patient (price year 2006), taking account of direct, indirect and intangible costs from a societal perspective. Direct costs included all expenses di- rectly related to leg ulcer care (dressings, bandages, topical agents, systemic treatment, diagnostic procedures, clinician fees, in-pa- tient treatment costs and transport); indirect costs related to loss of productivity; and intangible costs included impact on health- related quality of life. Estimates ranged from zero cost (i.e. no treatment) to EUR 44,462, with higher costs associated with ul- cers with arterial aetiology, larger wound size and no history of wound closure (Augustin 2012). A large part of ulcer treatment cost comprises nursing time. For the financial year 2006-2007 in Bradford, UK, GBP 1.69 million was spent on dressings and com- pression bandages and GBP 3.08 million on nursing time (esti- mates derived from resource use data for all wound types, not just venous leg ulcers) (Vowden 2009c). We were unable to identify additional, contemporary, international cost data.

Foot ulcers are a typical inconvenience of diabetes. They are most predominant under your enormous toes and also the bundles of your feet. Ulcers structure as an aftereffect of skin tissue separating and uncovering fundamental layers. These bruises can influence your feet down to the bones. Reflexology is a well known comprehensive & reciprocal treatment that advantages and enhances general wellbeing and in addition assuaging push and agony in different parts of the body. Reiterative foot reflexology graphs reflect your self-perception. These graphs are in light of zones to mirror your body in scaled down on your feet. In this paper a hybrid method which combines the reiterative foot chart with image processing technique is proposed. The image of affected foot is enhanced using colour image segmentation technique and then processed using reiterative foot chart.
Under certain conditions treatment with becaplermin in Germany is refundable. The German Federal Joint Com- mittee defines in its medicine directive, that the applica- tion of becaplermin is only indicated “if the treatment of diabetic neuropathic ulcers with intense and adequate wound care including total pressure relief was not suc- cessful.” Therefore becaplermin is only second line ther- apy. Apligraf is approved in Switzerland and the USA but due to opportunistic sales the access to treatment is also possible in Germany.

The spectrum of the most frequent contact allergens among leg ulcer patients mainly depends on the local practice of wound treatment. One study reported a direct relationship between the duration of leg ulcers and the number of multiple positive allergen sensitivities. From this study findings suggest that an ulcer of long duration has greater opportunity for contact with different allergens and leads to increased sensitivity to this allergens. 5

But obviously, I have been doing it the correct way . . . he can ’ t bend . . . I mean [he] couldn ’ t do it himself. But I don ’ t mind doing it, you know, as long as, shall I say, we both get support . . . And quite frankly, I feel that . . . we ’ ve been let down by the district nurses. I feel as though, yes, there ’ s probably other people more important than we are, but for something as serious as [leg ulcers and] lymphoedema, you have to have proper bandaging done, and because, yes, I can do it, but am I doing it right? Am I doing it correctly? Do I know what I ’ m looking for once the bandages come off and [he] gets a shower and you know he showers his legs. Do I know what I ’ m looking for? Because I don ’ t. I don ’ t know if it ’ s good or bad. We ’ ve said this before, haven ’ t we? . . . And as regards feedback, the only feedback we did get is from [nurse] at the lymphoedema clinic. And she said, yes, they ’ re going on all right. And she automatically says, but your ulcer is not healing. Have you been to your GP [general practitioner]? . . . And what does the practice nurse do there? ‘ Oh yes it ’ s okay, so don ’ t bother coming again ’ . So I mean, honestly, it seemed as though we were between a rock and a hard place.

opportunistic pathogen with innate resistance to many antibiotic classes, including antipseudomonal penicillins, carbapenems, aminoglycosides and ciprofloxacin [2, 3]. Treatment options for infections caused by antibiotic resistant P. aeruginosa is limited to carbapenems, but increasing resist- ance rates mediated in most cases by the production of carba- penemases such as metallo- β -lactamases (MBLs) are reported [4, 5]. In case of P. aeruginosa isolated from chronic wounds there is no consensus on the first-line antibiotic to be used . Besides intrinsic and acquired resistance to many antibi- otics, P. aeruginosa expresses many extracellular virulence factors (exotoxins S and T with ADP-ribosylating activity which cause disruption of the host cell cytoskeleton,
Tissue sample collection and preparation. Nine patients diagnosed with chronic venous leg ulcers were included in the study. As described below, four patients had S. aureus-containing wounds, four patients had P. aeruginosa-con- taining wounds, and one patient had a wound that contained both S. aureus and P. aeruginosa. Material (4-mm punch biopsy specimens) from chronic venous leg ulcers (Fig. 1) was obtained with the acceptance of the patients and in accor- dance with biomedical project protocols H-B-2008-023 and KA-20051011, which were approved by the Danish Scientific Ethical Board. Wound biopsy material was collected by a surgical team before cleansing and surgical preparation of the wound (2). The material was immediately transferred to phosphate-buffered saline with 4% paraformaldehyde and stored at 5°C before further preparation for microscopic investigation. The biopsy material for microscopic investigation was embedded in paraffin, cut into 4-m sagittal sections, and mounted on glass slides. Prior to microscopic investigation, the paraffin was removed from the tissue sections by immersing the glass slides twice in xylene (total, 10 min), twice
two calculated body mass index, whereas no relevant details about local pressure on the foot were provided in the remain- ing seven studies. Stratified randomization was not performed for the severity of DFUs, thus, the patient characteristics in each group were not balanced. Meanwhile, there were many other influencing factors, including the relatively small sample sizes, insufficient description of methodologic details, inad- equate follow-up time, and so on, which can result in clinical heterogeneity. Finally, because we retrieved only published literature, the document collection may be incomplete.
