Abstract Background Diabetic foot ulcers (DFUs) are the main cause of hospitalization in diabetic patients and they are considered a major worldwide health problem. Thus, there is a need to evaluate various treatment modalities. In this study we will assess the clinical efficacy of Silver nanoparticles dressing vs Standard Moist Wound Dressing (SMWD) in management of diabetic foot ulcers. Objective To compare wound outcome, limb salvage, healing time of diabetes related foot ulcers and cost effectiveness in terms of duration of hospital stay between Silver nanotechnology dressings and Standard moist wound therapy (SMWT) in management of diabetic foot ulcers. Patients and Methods This is a prospective randomized controlled study involving 34 patients with active diabetic foot ulcers, in a high volume tertiary referral vascular center. They were divided into 2 groups: 17 patients (group A) were prescribed SMWD and the other 17 patients (group B) received Silver nanoparticles wound dressing. Results Our study correlates with the study conducted by K.Suhas et al. which had observed that Silver nanoparticles wound dressing was safe and effective treatment for complex diabetic foot wounds and could lead to higher proportion of healed wounds and faster healing rates. At the end of the study, group B promised a better outcome as compared to group A. Conclusion The role of Silver nanoparticles wound dressing in healing of diabetic foot ulcers has been proposed as a novel method of manipulating the chronic wound environment in a way that it reduces bacterial burden and chronic interstitial wound fluid, increases vascularity and cytokine expression and to an extent mechanically exploiting the viscoelasticity of peri wound tissues.

Background: The study aimed to evaluate the ratio of venous contamination in diabetic cases without foot lesion, with foot lesion and with Charcot neuroarthropathy (CN). Materials and Methods: Bolus-chase three-dimensional magnetic resonance (MR) of 396 extremities of patients with diabetes mellitus was analyzed, retrospectively. Extremities were divided into three groups as follows: diabetic patients without foot ulcer or Charcot arthropathy (Group A), patients with diabetic foot ulcers (Group B) and patients with CN accompanying diabetic foot ulcers (Group C). Furthermore, amount of venous contamination classified as no venous contamination, mild venous contamination, and severe venous contamination. The relationship between venous contamination and extremity groups was investigated. Results: Severe venous contamination was seen in Group A, Group B, and Group C, 5.6%, 15.2%, and 34.1%, respectively. Statistically significant difference was seen between groups with regard to venous contamination. Conclusion: Venous contamination following bolus chase MR was higher in patients with CN.

Abstract Background and Aims Diabetes is rapidly increasing in prevalence worldwide and surgery in patients with diabetic foot is becoming more common. Foot complications are a major cause of admissions in diabetic patients, and comprise a disproportionately high number of hospital days because of multiple surgical procedures and prolonged length of stay in hospital. Diabetic foot is an umbrella term for foot problems in patients with diabetes mellitus. Foot disorders such as ulceration, infection and gangrene are the most common, complex and costly sequelae of diabetes mellitus. The optimal therapy for diabetic foot ulcers remains ill-defined. Saline-moistened gauze has been the standard method; however, it has been difficult to continuously maintain a moist wound environment with these dressings. This has led to the development of various hydrocolloid wound gels, which provided more consistent moisture retention. Refinements in topical ointments have resulted in the addition of various pharmacological agents including growth factors and enzymatic debridement compounds. Hyperbaric oxygen therapy and culture skin substitutes are other wound therapies that have been advocated. All these therapies are associated with significant expense and are being utilized in some situations without sufficient scientific evidence demonstrating their efficacy. Therefore, the search for an efficacious, convenient and cost-effective therapy continues. Negative Pressure Wound Therapy (NPWT) is a newer noninvasive adjunctive therapy system that uses controlled negative pressure using Vacuum-Assisted Closure device (VAC) to help promote wound healing by removing fluid from open wounds through a sealed dressing and tubing which is connected to a collection container. The use of sub-atmospheric pressure dressings, available commercially as a VAC device, has been shown to be an effective way to accelerate healing of various wounds. This was aimed to compare wound outcome, limb salvage, and cost effectiveness between Negative pressure wound therapy (NPWT) and Standard moist wound therapy (SMWT) in management of diabetic non ischemic foot ulcers. Methods we performed a cohort study involving 30 patients with active diabetic foot ulcers, in a high volume tertiary referral vascular center. They were divided into 2 groups: 15 patients (group A) were prescribed NPWT and the other 15 patients (group B) received SMWD. During follow up visits, progress of healing was evaluated and documented in the form of change in wound diameter, depth, up or down scaling along UTWC, wound status at 2, 4, 8, and 12 weeks and 4 weekly thereafter till complete epithelialization. Results As regard to ulcer depth there were statistically significant difference between the 2 groups during follow up duration of the study after 4 weeks with group A showing faster decrease in ulcer depth than group B denoting faster formation of granulation tissue. As regard to complete granulation of ulcer there were statistically significant difference between the 2 groups during follow up duration of the study markedly shown after 6 weeks with group A showing complete ulcer granulation faster than group B, with statistically significant difference as regard to number of days on dressing and follow up duration in weeks between the 2 groups with group A showing lesser number of days on dressing and shorter follow up duration in weeks than group B. Conclusion NPWT has a definitive role in promotion of proliferation of granulation tissue, reduction in the wound size, by and rapid clearing of bacterial load. Our data demonstrates that negative pressure wound dressings decrease the wound size more effectively than saline gauze dressings over the first 4 weeks of therapy. It is suggested that NPWT is a cost-effective, easy to use and patient-friendly method of treating diabetic foot ulcers which helps in early closure of wounds, preventing complications and hence promising a better outcome.

Background: Diabetic foot ulcers continue to pose significant global issue despite the advances made in the management of diabetes. It causes major foot complications if they are not addressed properly. It needs multidisciplinary approach for its care. While several advancements has taken place in wound care management, platelet rich plasma and stem cell therapy promises to offer a new hope in its management, aiding in cellular and tissue regeneration. The purpose of the present study was to compare Platelet-Rich Plasma versus conventional dressing in the management of diabetic foot ulcers.Methods: This prospective study was focused on 20 diabetic foot ulcers, carried out in a surgical unit of ACS Medical College and Hospital, Chennai, Tamil Nadu, from January 2018 to June 2018. Patients were divided into two groups; Group A received conventional ordinary dressing (N=10, 50%) and Group B received PRP dressing (N = 10, 50%). The mean follow-up period was 8 weeks.Results: The estimated time of wound healing was 8 weeks and healing was found to be more effective for patients in group B compared to patients in group A; the PRP group was found to be more effective in wound healing with fewer complications, less infection, exudates and pain.Conclusions: There have been considerable advances in the use of PRP in therapeutic processes in recent years in tissue regeneration therapy. PRP is a powerful tool for the treatment of chronic wounds and very promising for diabetic foot wounds; PRP enables healing, and reduces amputation rates, infection and exudates.

Background We are trying to evaluate silver nanoparticles’ effectiveness (SilvrSTAT Gel) in accelerating healing rate of nonischemic diabetic foot ulcers (DFUs). Methods This prospective, double-blind, randomized, controlled study includes 80 patients with nonischemic DFUs classified into 2 groups. Group A was subjected to SilvrSTAT Gel dressing, and group B was subjected to conventional dressing (wet-to-moist dressing with or without povidone-iodine). All cases had minimal debridement before treatment. In both groups, all cases were nonischemic after successful revascularization either by bypass surgery or endovascular therapy. Results The healing rate of the SilvrSTAT group was significantly higher than that of the conventional group. The healing rate per week of the SilvrSTAT group was considerably higher than that of the conventional group ( P < .0001). The rate of complete healing for ulcers in group A was achieved in 22 patients (55%) by the 6th week, while 29 (72.5%), 34 (85%), and 36 (90%) patients were healed entirely by the 8th, 10th, and 12th weeks, respectively. In group B: 20 (50%), 27 (67.5%), and 30 (75%) patients were completeley healed by the 8th, 10th, and 12th weeks, respectively. Conclusions SilvrSTATGel is effective in the treatment of DFU.

Background: Diabetic foot a complication of diabetes can lead to significant morbidity and have financial burden. The standard of dressing diabetic foot ulcers has been saline dressings. Negative pressure vacuum devices have come and had a significant impact on treatment of diabetic ulcers. But in developing countries the cost associated with it makes it inaccessible to a large population. Our study aims to compare the use of modified vacuum dressing against saline dressing and compare healing rates, costs involved and hospital stay of patients.Methods: Our study was prospective study of 80 patients randomised into two groups, of 40 each. Group A consisted of patients with modified vacuum dressing and group B with wet saline dressing. Simple randomisation technique was used. They were compared for healing rates, hospital stay and cost involved.Results: There was a 43.75% decrease in area of the ulcer in group A compared to 25.15% in group B after 4 weeks. Decrease in wound depth was 55.41% and 26.94% in group A and B respectively. The mean hospital stay was 33.18 days in group A compared to 45.58 days in group B. The average cost incurred for patients in group A was rupees 14,381 compared to 19,465 rupees in group B.Conclusions: From our study we found that modified vacuum dressing in spite of being cheap it reduces healing time, hospital stay there by the cost incurred to patients. So we recommended modified vacuum dressings as a go to method of treating diabetic foot ulcers.

Background: Diabetic foot ulcer is a very common condition encountered in surgical practise. Wound management pose a good challenge for a treating surgeon due to its physical, mental and social implications. The devitalised necrotic tissue present in ulcer does not favour the wound healing as it increases the chance of infection and delays appearance of granulation tissue. Hence debriding of devitalised tissue plays a key role in wound care. In present study ,we used papain urea based preparation in dressings which is a autolytic agent. This study was conducted to evaluate the effectiveness of use of papain urea based preparations compared with regular conventional dressing in diabetic foot ulcer management.Methods: This was a prospective study conducted in K. R. Hospital, Mysore, Karnataka, India. 60 eligible subjects with diabetic foot ulcers were selected and subjects were randomly allocated into two groups Group A and Group B with 30 subjects in each group. Subjects in Group A underwent dressing with papain urea based preparation and in Group B underwent regular conventional dressing. Results were assessed with respect to percentage decrease in necrotic tissue, incidence of infection, appearance of granulation and hospital stay.Results: Among Group A subjects percentage reduction of necrotic tissue was more, granulation appeared early and the hospital stay was less compared to Group B subjects which were statistically significant. However, there was no significant difference with respect to incidence of infection in both groups.Conclusions: Papain urea based preparation is effective in diabetic foot ulcer care.

Introduction: Traditionally, moist dressings are being in used routinely by surgeons for management of diabetic foot ulcers. Recently, there is an encouraging trend of using VAC dressings in such patients. This study aimed to compare the outcome of VAC with moist dressing for management of diabetic foot ulcer. Study Design: Prospective randomized controlled trial. Setting: Department of Surgery, Al-Bukyriah General Hospital, Al-Bukayriah, Alqaseem KSA. Period: June 2012 to 07 December 2016. Methods and Material: 200 patients with diabetic foot ulcers. The patients were divided in two equal groups containing 100 patients each. In group A, 100 patients received VAC dressing treatment while in group B, 100 patients received wet dressings. Wound size, % reduction in wound size, appearance of granulation tissue and fate of wound were main outcome measured which were noted at start of study and at the end of study (4th week of therapy). Results: In group A, there were 73 (73%) men and 27 (27%) women with a mean age of 54.98+7.68 years and in group B, there were there were 75 (75%) men and 25 (25%) women with a mean age of 55.23+6.98 years. Size of wound before treatment in group A was 14.23± 6.78 cm2 which reduced to 5.11±1.91 cm2 at 4th wee and in group B it was 14.41±5.93 cm2 in the start which reduced to 11.29±3.63 cm2 at 4th week (p<0.05). Mean %reduction in wound size in group A was 63.22±9.19 and 22.92±7.18 in group B (p<0.05). In group A, 43 (43%) wounds healed spontaneously with shrinkage and group B only 2(2%) healed spontaneously (p<0.05). Conclusions: VAC therapy is superior to moist dressing in terms of achieving early granulation tissue, reduction in wound size and spontaneous wound shrinkage.

Abstract Background and aims: Infected foot ulcer is one of the most feared complications of diabetes mellitus. Staphylococcus aureus is the most frequently isolated pathogen in diabetic foot infections. The aim of this study was to evaluate the prevalence of S. aureus strains involved in producing foot infections in diabetic patients and the antibiotic resistance pattern of these strains. Material and methods: The study included 33 S. aureus strains isolated from 55 diabetic foot ulcers. The subjects were selected from the 2465 patients with diabetes mellitus hospitalized in the Timişoara Diabetes Clinic, between 2011 and 2013. Germs’ identification relied on cultural and biochemical characteristics. Final identification and antimicrobial testing were performed using the Vitek 2 (Bio Merieux France) automatic analyzer. Results: All the 55 samples collected from diabetic foot ulcers were positive. We isolated 64 bacterial strains (some samples were positive for 2 microorganisms). The most frequently isolated germ was S. aureus, in 33 samples (51.56%). All these S. aureus strains showed resistance to benzylpenicillin, while only 33.33% were methicillin-resistant (MRSA). Conclusions: The most frequently isolated germ in the wound secretions from diabetic foot ulcers was S. aureus. The highest percentage of antimicrobial resistance was recorded to benzylpenicillin and erythromycin.

Diabetic Foot Ulcer (DFU) is one of the major complications of Diabetes. Patients with Diabetic Foot ulcers have a high susceptibility to microbial infections and are the leading cause of hospitalization and amputation of lower limbs. In the era of increased prevalence of bacterial resistance and outbreak of resistant infectious diseases, it is very essential to develop effective therapeutic strategies towards multi-drug resistant pathogens. The antimicrobial properties of silver nanoparticles have been well studied, therefore their use in biomedicine and pharmacology is a trend. Herein we present the use of Phyto-mediated synthesized AgNPs for the treatment of diabetic foot ulcers by topical administration. The nanoparticles were synthesized by reducing silver nitrate using Terminalia chebula fruit extract. The nanoparticles were analyzed and characterized using UV-Visible Spectrophotometer, FTIR, XRD, SEM with EDAX, TEM, and DLS. The synthesized silver nanoparticles were assayed for antimicrobial activity against five Diabetic Foot Ulcer bacterial isolates i.e. Escherichia coli, Klebsiella Pneumoniae, Pseudomonas aeruginosa, Streptococcus aureus, and Bacillus subtilis. The bactericidal property of synthesized nanoparticles was analyzed by the Agar well diffusion method, which revealed the remarkable antimicrobial effects against all the selective pathogenic bacterial isolates of Diabetic foot ulcers in the present study. These results constituted the basis for further studies on the use of plant-based silver nanoparticles for the treatment of Diabetic Foot ulcers from different origins

Abstract Background: Diabetic foot ulcers (DFU) are associated with high morbidity and mortality globally. Mortality in patients hospitalized for DFU in Nigeria is unacceptably high. This study was undertaken to determine factors that predict mortality in patients hospitalized for DFU in Nigeria.Methods:The current study was part of Multi-centre Evaluation of Diabetic Foot Ulcer in Nigeria (MEDFUN), an observational study conducted in six tertiary healthcare institutions across the 6 geopolitical zones of Nigeria. Consecutive type 1 or 2 diabetic patients hospitalized for DFU who consented to participate were recruited and subjected to relevant clinical, biochemical and radiological assessments and multidisciplinary care until discharge or death. Data for type 1 diabetes mellitus (DM) patients were expunged from current mortality analysis due to their small number.Results: Three hundred and twenty three type 2 DM subjects with mean age and mean duration of DM of 57.2 11.4 years and 8.7± 5.8 years respectively participated in this study. The median duration of ulcers was 39 days with a range of 28 to 54 days and majority (79.9%) presented with advanced ulcers of at least Wagner grade 3. Mortality of 21.4% was recorded in the study, with the highest mortality observed among subjects with Wagner grade 5. Variables significantly associated with mortality with their respective p values were DM duration more than 120 months (p 0.005), ulcer duration > one month (p 0.020), ulcer severity of Wagner grade 3 and above (p 0.001), peripheral arterial disease (p 0.005), proteinuria (p <0.001), positive blood cultures (p<0.001), low HDL (p <0.001), shock at presentation (p<0.001), cardiac failure (p 0.027),and renal impairment (p <0.001). On Multivariate regression analysis, presence of bacteraemia (OR 5.053; 95% CI 2.572-9.428) and renal impairment (OR 2.838; 95% CI 1.349 – 5.971) were significantly predictive of mortality independent of other variables.Conclusions: This study showed high intra-hospital mortality among patients with DFU, with majority of deaths occurring among those with advanced ulcers, bacteremia, cardiac failure and renal impairment. Prompt attention to these factors might be helpful in improving survival from DFU in Nigeria.
