Purpose: The number of patients who are suffering from diabetes nowadays is increasing significantly. In some countries, the percentage of population who suffer from this disease can reach up to 20%. Diabetic patients have to deal with their medical conditions and any further complications that this disease may cause. One of the most common conditions is the Diabetic Foot Ulcer (DFU). The early detection of these ulcers can help and may save the life of diabetic patients. Methods: This work proposes a mobile application for the detection of possible ulcers using a smart phone along with a mobile thermal camera (FLIR ONE). The proposed system captures thermal images of the feet from the thermal camera. The app that identifies ulcers was built using Android studio. The images were acquired to the Samsung S6 smart phone using the FLIR ONE SDK. Image processing techniques were deployed based on Open CV Library. The procedure of detecting possible ulcers was implemented based on analyzing the thermal distribution on the two feet. The developed application compares the difference between the temperature distribution on the two feet and checks if there is a Mean Temperature Difference (MTD) greater than 2.2oC (the value which indicates a possible ulcer development). Results: The system was tested under simulated conditions by heating different locations of the subjects’ feet to different temperature ranges; one image with temperature less than 2.2oC and another three images with temperature greater than 2.2oC. The system has successfully identified possible ulcer regions along with an image showing the location of the possible ulcers. Conclusions: This work is a very first step in developing a complete mobile thermal imaging system that can be validated clinically in the future.

Diabetic foot ulcers (DFUs) are a serious complication in diabetic patients and lead to high morbidity and mortality. Numerous dressings have been developed to facilitate wound healing of DFUs. This study investigated the wound healing efficacy of silver-releasing foam dressings versus silver-containing cream in managing outpatients with DFUs. Sixty patients with Wagner Grade 1 to 2 DFUs were recruited. The treatment group received silver-releasing foam dressing (Biatain® Ag Non-Adhesive Foam dressing; Coloplast, Humlebaek, Denmark). The control group received 1% silver sulfadiazine (SSD) cream. The ulcer area in the silver foam group was significantly reduced compared with that in the SSD group after four weeks of treatment (silver foam group: 76.43 ± 7.41%, SSD group: 27.00 ± 4.95%, p < 0.001). The weekly wound healing rate in the silver foam group was superior to the SSD group during the first three weeks of treatment (p < 0.05). The silver-releasing foam dressing is more effective than SSD in promoting wound healing of DFUs. The effect is more pronounced in the initial three weeks of the treatment. Thus, silver-releasing foam could be an effective wound dressing for DFUs, mainly in the early period of wound management.

Health-state utility values of diabetic foot ulcer (DFU) patients are necessary for clinical praxis and economic modeling. The purpose of this study was to estimate utility values in DFU patients using the EuroQol-5-dimension-5-level (EQ-5D-5L) and composite time trade-off (cTTO). The EQ-5D-5L and cTTO were used for estimating utility values. Data were collected from 228 patients referred to the largest governmental diabetes center in the South of Iran, Yazd province. When appropriate, independent sample t-test or analysis of variance test was used to test the difference in the utility values in each of the demographic and clinical characteristics of the patients. Finally, the BetaMix was used to identify predictors of the utility values. The means of EQ-5D-5L and cTTO values were 0.55( SD 0.21) and 0.67( SD 0.23), respectively. Anxiety and pain were the most common problems reported by the patients. The difference between the mean EQ-5D-5L values was significant for age, grade of ulcer, number of comorbidities, and having complications. In addition, variables of gender, age, grade of ulcer, and having complications were significant predictors of the EQ-5D-5L. The difference between the mean cTTO values was significant for age, employment status, grade of ulcer, number of comorbidities, and having complications. Moreover, variables of gender, age, grade of ulcer, number of comorbidities, and developing complications were significant predictors of cTTO. The current study provided estimates of utility values for DFU patients for clinical praxis and economic modeling. These estimates, similar to utilities reported in other studies, were low. Identifying strategies to decrease anxiety/depression and pain in patients is important to improve the utility values.

Diabetes mellitus is a metabolic disorder which is characterized by multiple long-term complications that affect almost every system in the body. Foot ulcers are one of the main complications of diabetes mellitus. However, there is limited evidence on the occurrence of foot ulcer and influencing factors in Ethiopia. An institutional-based cross-sectional study was conducted in Gondar University Hospital, Ethiopia, to investigate foot ulcer occurrence in diabetic patients. Systematic random sampling was used to select 279 study participants. Bivariate and multivariable logistic regression model was fitted to identify factors associated with diabetic foot ulcer. Odds ratio with 95% confidence interval was computed to determine the level of significance. Diabetic foot ulcer was found to be 13.6%. Rural residence [AOR = 2.57; 95% CI: 1.42, 5.93], type II diabetes mellitus [AOR = 2.58; 95% CI: 1.22, 6.45], overweight [AOR = 2.12; 95% CI: 1.15, 3.10], obesity [AOR = 2.65; 95% CI: 1.25, 5.83], poor foot self-care practice [AOR = 2.52; 95% CI: 1.21, 6.53], and neuropathy [AOR = 21.76; 95% CI: 8.43, 57.47] were factors associated with diabetic foot ulcer. Diabetic foot ulcer was found to be high. Provision of special emphasis for rural residence, decreasing excessive weight gain, managing neuropathy, and promoting foot self-care practice would decrease diabetic foot ulcer.

Objective: (1) To evaluate the effects of G-CSF in eliminating infection in diabetic foot wound (2) Tocompare the effects with conventional diabetic foot management. Design: Prospective, open, randomized comparativestudy. Setting: Medical&Surgical Department of Allied, DHQ Hospital & Nawaz Medicare Faisalabad. Period: FromJan 2000 to Nov 2000 Patients & Methods: Fifty diabetic patients with foot infections were included in this study. Themean age was 52 years ranging from 27 to 60 years. They were divided into two equal groups(Group A and Group B).Results: The male patients were 41(82%) and female 9(18%). Forty six percent of patients were on oral hypoglycaemicdrugs, and 54% on insulin. The trauma preceding infection was 20%, Peripheral neuropathy 94% and peripheralvascular disease 34%. Thirty two percent of patients were smoker. Group A were subjected to G-CSF ( Neupogen )therapy (n=25) subcutanously daily for 5days in addition to conventional measures. Whereas patients in Group Breceived only conventional therapy. Both groups received similar antibiotic and insulin treatment. G-CSF therapy wasassociated with earlier eradication of pathogens from the infected ulcer (median 5 [range 2-11] vs11 [6-31] days in thegroup B; (p=<O.000I), quicker resolution of cellulitis (6 vs l4 days; p<O.0001), shorter hospital stay (8 vsl6 days;p<O.000l), and a shorter duration of intravenous antibiotic treatment (7 vs l4 days ;p—0.0001).No G-CSF treatedpatient needed surgery, whereas three patients in group B underwent toe amputation and six had extensivedebridement under anaesthesia (p=0.00 1). G-CSF therapy was generally well tolerated. Conclusion: Granulocytecolony stimulating factor (G-CSF) may be used as a good adjuvant therapy along with conventional measures for themanagement of diabetic foot infection, as it promotes the healing of diabetic foot ulcer/cellulitis and consequentlyprevents many hazardous complications like amputation of limbs, long hospital stays, extensive and prolonged antibioticuse and last but not the least the total misery of the patients.

Community nurses face numerous challenges in both diagnosing and effectively treating their patients. The diabetic patient has complex needs requiring a holistic approach. With a reported increase in diabetic patients, and a possible decline in some routine screening following Covid-19 pandemic, complications in diabetic patients are likely to rise. It is estimated that 25% of diabetic patients will develop a diabetic foot ulcer (DFU), with a reported 43% of DFU already infected at first presentation to a health professional. NICE categorise the level of infection in DFU based on standardised assessments such as SINBAD. A high categorised DFU has the possibility of osteomyelitis. It is imperative that osteomyelitis is treated immediately to achieve positive outcomes, benefitting the patients' health and wellbeing in addition to reducing the financial implications to the NHS.

The rising prevalence of diabetes estimated at 3.6 million people in the UK represents a major public health and socioeconomic burden to our National Health Service. Diabetes and its associated complications are of a growing concern. Diabetes-related foot complications have been identified as the single most common cause of morbidity among diabetic patients. The complicating factor of underlying peripheral vascular disease renders the majority of diabetic foot ulcers asymptomatic until latter evidence of non-healing ulcers become evident. Therefore, preventative strategies including annual diabetic foot screening and diabetic foot care interventions facilitated through a multidisciplinary team have been implemented to enable early identification of diabetic patients at high risk of diabetic foot complications. The National Diabetes Foot Care Audit reported significant variability and deficiencies of care throughout England and Wales, with emphasis on change in the structure of healthcare provision and commissioning, improvement of patient education and availability of healthcare access, and emphasis on preventative strategies to reduce morbidities and mortality of this debilitating disease. This review article aims to summarise major risk factors contributing to the development of diabetic foot ulcers. It also considers the key evidence-based strategies towards preventing diabetic foot ulcer. We discuss tools used in risk stratification and classifications of foot ulcer.

Background. Acral lentiginous melanoma (ALM) is a less-common form of melanoma in US, and it accounts for about 5% of all diagnosed melanomas in US. ALM is often overlooked until it is well advanced because of the lesion’s location and its atypical appearance in the early stages. We present a case of ALM initially presented as a diabetic foot ulcer.Case Report. An 81-year-old man initially presented to the primary care clinic with a right foot diabetic ulcer. There was a large plantar, dark-colored ulcer that bled easy. Initial excision biopsy revealed Clark’s Level IV ALM. Subsequent definitive wide excision and sentinel node biopsy confirmed ALM with metastasis to inguinal lymph nodes (stage IIIb). The treatment included wide margin excision of the lesion with en bloc amputations of 4th and 5th toes, followed by adjuvant chemotherapy.Discussion. The development of ALM may potentially relate to diabetes as a reported higher prevalence of diabetes with ALM patients.Conclusion. The difficulty in early diagnosing of ALM remains as a formidable challenge particularly in diabetic patients who commonly develop plantar foot ulcers due to the diabetic neuropathy. This case reiterates the importance of a thorough foot exam in such patients.

Diabetic foot ulcer (DFU) has been identified as the leading reason for hospitalization among patients with diabetes. Patients with diabetes are at greater risk of complications, the most important of them are diabetic neuropathy and peripheral vascular disorders leading to the development of foot ulcers. The problem is generally faced and as well is considered as one among the most common complications of diabetes that affect millions of people all over the world. The current study, aimed to document the clinical profile and healing outcome of diabetic foot ulcer management which may become guidance for further improvement in wound management among diabetic foot ulcer patients. Cross sectional descriptive study was conducted over one-year period of time. A total of 246 Diabetic patients with a foot ulcer of Grade 1 to 3 participated in the study. Patients with higher grade ulcers of Grade 4 and 5 were excluded from the study. Final data analysis of 160 patients was done using SPSS version 20. The prevalence of Grade 2 and 3 ulcers were observed 54.37% and 31.8 % while Grade 1 ulcer was observed 13.75%. No risk factors were found to be significantly associated with diabetic foot ulcer. Wound was healed well in 50 % and partially healed in 21 % of the participants. Wound remains unchanged in 3 % of study participants, while 8% of participants underwent toe amputation. Foot ulceration is a preventable in many diabetic patients with adequate education, routine foot care and attention to foot wear.
