BACKGROUND Diabetes mellitus (DM) is one of the most prevalent diseases worldwide and is associated with increased morbidity and mortality. One of the microvascular complications of DM is diabetic foot ulcer (DFU), which is associated with increased mortality from serious infections and decreased functional capacity of the patient due to amputation. Uncontrolled diabetes is a significant risk factor for poor wound healing. There is a need for alternative treatments that can promote wound healing in these patients. Several studies have shown the effect of low-level laser therapy (LLLT) on wound healing in patients with DFU. LLLT is a potential therapeutic approach in patients with DFU. CASE REPORT A 55-year-old male patient presented with a history of DM, diabetic neuropathy, and diabetic foot. The patient had uncontrolled blood sugar levels, with an HbA1C of 9.3%. The patient received therapy in the form of wound care with normal saline, topical antibiotics, and LLLT, with a dose of 10 J/cm² with a frequency of therapy 3 times per week. After 12 weeks of therapy, there was improvement, characterized by wound tissue growth and no significant adverse effects during therapy. CONCLUSIONS LLLT can provide benefits in patients with DFU and uncontrolled diabetes. The wound showed improvement after 12 weeks of therapy, and there were no significant adverse effects during therapy. LLLT is a minimally invasive, easy-to-use, and inexpensive therapeutic option to induce wound healing in patients with DFU and uncontrolled diabetes.

Treatment of lower limb ischemia in patients with diabetes is challenging because of the location of the ulcers and the complexity of their pathogenesis. Carbon dioxide fractional laser (CO2FL) therapy in conjunction with tibial periosteum distraction could become a substitute for conventional methods. We herein describe a patient diagnosed with ischemic diabetic foot with a complex ulcer in the upper third of the tibia. Laser irradiation (Deep FX mode with 30 mJ of energy and 10% density) was applied to the entire region of skin below the knee after surface anesthesia, and this treatment was performed twice a week until the ulcer healed. Computed tomography angiography showed successful establishment of a blood supply to the back of the right foot after treatment. Skin grafting was successfully performed, with only a few wounds remaining on the foot 8 months after treatment. The pain score was significantly decreased at the last follow-up. No complications occurred. This case report provides guidance for the performance of CO2FL, a fast, easy, accurate treatment in patients with diabetes. CO2FL can target lower limb arterial occlusive disease accompanied by refractory ulcers, addressing the underlying vascular occlusion and dysfunction as well as promoting microcirculation and wound healing.

Cutaneous malignant melanoma (cMM) can develop at any site, but one-third of cases primarily affect the lower extremities, with ankle and foot lesions representing 3-15% of all cases. However, cMM may become a clinical conundrum when it presents as chronic ulceration that is clinically indiscernible from other lower extremity ulcers in patients with diabetes. We present the case of a 71-year-old female patient with a longstanding history of diabetes, hypertension, obesity, chronic kidney disease and heart failure who presented to our hospital with a fungating heel ulcer. The lesion was initially managed in another hospital as a neuropathic diabetic foot ulcer (DFU), treated by multiple local wound debridement. However, the ulcer progressed into a fungating heel lesion that interfered with the patient\'s mobility and quality of life. Consequently, the patient was referred to our specialist diabetic foot service for further management. Excisional biopsy of the lesion disclosed a cMM. Positron emission tomography/computed-tomography scanning revealed hypermetabolic ipsilateral inguinal lymphadenopathy, and a right cerebral metastasis for which palliative chemotherapy was initiated. Immunotherapy was considered, but the patient died before it was started. Atypical foot ulcers in patients with diabetes warrant a careful diagnostic approach, especially for recalcitrant cutaneous lesions not responding to standard therapies. Conscientious management, without undue delay in obtaining a histopathological diagnosis, might lead to early diagnosis of melanoma and potentially more favourable outcomes. This case highlights the importance of consideration of atypical foot lesions, in general practice in addition to referral centres, to try to identify alarming features and act accordingly.

BACKGROUND: Gout is a chronic disease characterized by deposition of monosodium urate crystals. Tophi develop in some individuals with untreated or uncontrolled gout, which leads to ulcerations, cosmetic problems, mechanical obstruction of joint movement, joint damage and musculoskeletal disability. Currently, the treatment of gouty tophi is controversial and challenging. Both surgical and internal medical treatments have limitations and require further exploration in clinical practice.
METHODS: In Case 1, we treated a patient with severe infection of diabetic foot ulcers with concomitant multiple gouty tophi in the same limb. A systematic management strategy was formulated to close the wound and save the limb. The ulcers healed successfully after half a year. In Case 2, a giant gouty tophi located in the first metatarsophalangeal joint of the left foot was removed by surgical treatment and vancomycin-loaded bone cement implantation. In Case 3, we present a case of gouty tophi that was resolved by standardized systemic medical management.
METHODS: Three patients were all diagnosed with gout accompanied by gouty deposition, although there were other different comorbidities.
METHODS: In case 1, we used debridement to gradually remove gouty tophi. In case 2, the giant gouty tophi was removed by surgical operation. In case 3, the gouty tophi disappeared after standardized treatment with medicine, diet and lifestyle management.
RESULTS: Three patients underwent different treatment therapies to remove gouty tophi based on their specific conditions.
CONCLUSIONS: We explored effective interventions for tophi in gout by surgical or other interventions in combination with pharmacotherapy.

BACKGROUND: Diabetic foot ulcers (DFU) are a devastating complication of diabetes. There are numerous challenges with preventing diabetic foot complications and barriers to achieving the care processes suggested in established foot care guidelines. Multi-faceted digital health solutions, which combine multimodal sensing, patient-facing biofeedback, and remote patient monitoring (RPM), show promise in improving our ability to understand, prevent, and manage DFUs.
METHODS: Patients with a history of diabetic plantar foot ulcers were enrolled in a prospective cohort study and equipped with custom sensory insoles to track plantar pressure, plantar temperature, step count, and adherence data. Sensory insole data enabled patient-facing biofeedback to cue active plantar offloading in response to sustained high plantar pressures, and RPM assessments in response to data trends of concern in plantar pressure, plantar temperature, or sensory insole adherence. Three non-consecutive case participants that ultimately presented with pre-ulcerative lesions (a callus and/or erythematous area on the plantar surface of the foot) during the study were selected for this case series.
RESULTS: Across three illustrative patients, continuous plantar pressure monitoring demonstrated promise for empowering both the patient and provider with information for data-driven management of pressure offloading treatments.
CONCLUSIONS: Multi-faceted digital health solutions can naturally enable and reinforce the integrative foot care guidelines. Multi-modal sensing across multiple physiologic domains supports the monitoring of foot health at various stages along the DFU pathogenesis pathway. Furthermore, digital health solutions equipped with remote patient monitoring unlock new opportunities for personalizing treatments, providing periodic self-care reinforcement, and encouraging patient engagement-key tools for improving patient adherence to their diabetic foot care plan.

Biosurgery (larval therapy) has been used for centuries. However, in recent times, this treatment has been replaced with the use of antibiotics for the treatment of wounds. Due to increasing antibiotic resistance, larval therapy is once again coming to the fore as an effective and efficient treatment. Due to the increasing ageing population, along with an increase in patients with arterial occlusive disease, diabetes and immobility, the number of patients with hard-to-heal wounds will increase. The stressors associated with wounds, such as pain, limited physical functionality, depression and social withdrawal, have a negative impact on patient quality of life. This case report documents the performance of biosurgery in a patient with multimorbidities.

UNASSIGNED: To evaluate the role of foot muscle amide proton transfer weighted (APTw) contrast and tissue rest perfusion in quantifying diabetic foot (DF) infection and its correlation with blood parameters.
UNASSIGNED: With approval from an ethical review board, this study included 40 diabetes mellitus (DM) patients with DF and 31 DM patients without DF or other lower extremity arterial disease. All subjects underwent MRI, which included foot sagittal APTw and coronal arterial spin labeling (ASL) imaging. The normalized MTRasym (3.5 ppm) and the ratio of blood flow (rBF) in rest status of the affected side lesions to the non-affected contralateral side were determined. The inter-group differences of these variables were evaluated. Furthermore, the association between normalized MTRasym (3.5 ppm), rBF, and blood parameters [fasting blood glucose (FBG), glycosylated hemoglobin content, C-reactive protein, neutrophil percentage, and white blood cell count] was explored. Using an ROC curve, the diagnostic capacity of normalized MTRasym (3.5 ppm), BF, and blood biochemical markers in differentiating with or without DF in DM was assessed.
UNASSIGNED: In the DF group, MTRasym (3.5 ppm) and BF in lesion and normalized MTRasym (3.5 ppm) were higher than those in the control group (p < 0.05). In addition, correlations were identified between normalized MTRasym (3.5 ppm) and blood parameters, such as C-reactive protein, glycosylated hemoglobin content, FBG, neutrophil ratio, and white blood cell (p < 0.001). Meanwhile, association between BF in lesion and blood parameters, such as C-reactive protein, neutrophil percentage, and FBG (p < 0.01). AUC of normalized MTRasym (3.5 ppm) in identifying with/without DF in patients with DM is 0.986 (95% CI, 0.918-1.00) with the sensitivity of 97.22% and the specificity of 100%.
UNASSIGNED: Normalized MTRasym (3.5 ppm) and the BF in lesion may be treated as a safer and more convenient new indicator to evaluate the tissue infection without using a contrast agent, which may be useful in monitoring and preoperatively assessing DF patients with renal insufficiency.

Diabetic foot is a syndrome complex that presents with a serious complication arising from a diabetic ulcer. Poor blood circulation and nerve injury (neuropathy), especially in the limbs, can result from persistently elevated blood sugar levels. These elements play an important role in the formation of diabetic ulcers, which frequently occur on the feet and are prone to infection and sluggish healing. These ulcers have the potential to worsen and develop diabetic foot, a more serious ailment if left untreated. Diabetic foot issues can lead to increased vulnerability to infections, gangrene, and in severe cases, amputation. Diabetes patients may fail to notice small wounds or infections because of reduced feeling from neuropathy, which can lead to more serious problems. Moreover, decreased blood flow makes it more difficult for the body to mend itself, which makes diabetic foot issues more difficult to manage and cure. Glycemic management, timely medical intervention, and routine foot care are essential for preventing and lessening the severe effects of diabetic foot. We herein highlight the case of a 57-year-old male with a traumatic diabetic foot in whom indocyanine green (ICG) dye was used to identify the uptake of the involved tissue. The aspect of this case is the late presentation of a patient with uncontrolled diabetes. Further, we can better manage the patient in the preoperative phase by using ICG.

BACKGROUND: Diabetic foot ulcer (DFU) is known as a serious complication of diabetes mellitus in patients with diabetes, imposing heavy medical costs on healthcare systems due to its chronic nature. patients with severe diabetic foot ulcer are often disabled to work, and some of them may even die, leading to associated productivity losses. Since no previous study has investigated the economic burden of DFU in Iran, this study is to estimate the economic burden of diabetic foot disease in Iran.
METHODS: In this descriptive cross-sectional study, randomly selected samples consisted of 542 patients with DFU, hospitalized in the hospitals of Shahid Beheshti University of Medical Sciences. The demographic profile and cost data used in this analysis were derived from a researcher-designed checklist. Lost productivity was calculated based on Human Capital Approach, and the total economic cost of DFU was determined using patient-level data on costs and prevalence data from the global burden of diseases reports. All analyses were performed using SPSS software (Version 23), and Microsoft Excel (Version 19).
RESULTS: The economic burden of DFU in Iran in two scenarios of discounting future costs and not discounting them was about $8.7 billion and $35 billion, respectively (about 0.59 and 2.41% of GDP). 79.25% of the estimated costs in this study were indirect costs and productivity losses, of which 99.34% (7,918.4 million Dollars) were productivity losses due to premature death. 20.75% (2,064.4 million dollars) of the estimated costs in this study were direct costs. The average length of stay (LOS) was 8.10 days (SD = 9.32), and 73.3% of patients recovered and were discharged after hospitalization and 7.6% died. The majority of the costs are imposed on the age group of 60-69 year (53.42% of the productivity lost due to hospital length of stay, 58.91% of the productivity lost due to premature death & 40.41% of direct costs).
CONCLUSIONS: DFU represents a heavy burden to patients, Iran\'s health system, and the economy. Early prevention strategies need to be prioritized in making public health policies. These policies and decisions can be in the area of changing lifestyle, health education, changing people\'s behavior, and encouraging physical activity that targeted high-risk populations in order to reduce the prevalence of diabetic foot and resulting substantial economic burden.

BACKGROUND: AS is a malignant tumor that originates from vascular endothelial cells and is known for a high rate of local recurrence and metastasis.
METHODS: A 48-year-old male presented with cutaneous epithelioid AS. Cutaneous AS of the foot is quite rare, especially in the absence of predisposing factors, and in this patient it was previously misdiagnosed as a DFU.
CONCLUSIONS: Physicians should be aware of this rare presentation of cutaneous AS. The authors of the current report advise regular clinical reassessment of chronic ulcers and biopsies of nonhealing wounds, even when adequate wound treatment has been administered, with the goal of identifying ulcerated skin malignancies and preventing delay in providing appropriate treatment.
