RESUMEN
Charcot neuro-osteoarthropathy (CNO) is a manifestation of peripheral neuropathy as a chronic complication of diabetes mellitus but, less frequently, can be associated to other conditions such as alcoholism or neurotoxic therapies. An increasingly emerging cause of CNO is the use of oncological drugs which can cause neuropathic damage. The use of these therapies dramatically increased in recent years. CNO leads to a progressive degeneration of the foot's joints and to bone destruction and resorption which ends in deformities. These alterations in the foot's anatomy determine a high risk of ulceration, infection, and osteomyelitis. The superimposition of osteomyelitis on CNO increases the risk of major amputation, already high in patients suffering either from only CNO or osteomyelitis alone. We report the case of a 61-year old nondiabetic woman affected by CNO as a consequence of antiblastic therapy for breast cancer and the subsequent overlap of osteomyelitis, confirmed by magnetic resonance imaging. This case underlines how it is necessary to consider CNO as a possible complication of antiblastic therapy in the view of the severe consequences of missing its diagnosis.
RESUMEN
Background: Diabetes mellitus (DM) is associated with a higher prevalence of many forms of cancer. Diabetic foot syndrome (DFS) is associated with higher risk of lower limb amputation and mortality not all explainable with a cardiovascular profile at greater risk compared with DM patients without DFS. DFS could be associated with an increasing cancer incidence. To explore a possible link between DFS and cancer, comparing two cohorts of patients (DFS+ and DFS-) with a cohort of superimposable non-DM controls. Methods: We retrospectively analysed the databases of our department for all consecutive patients admitted between January 2019 and December 2021, selecting all DM pts, and sorting DFS+ pts, admitted for foot complications, from DFS- ones, admitted for other reasons. Cases of pancreatic cancer as well as cancer-related admissions were excluded. Patients were compared to non-DM patients admitted for non-oncological medical problems. The primary endpoint was to compare the prevalence of cancer among the groups, while the secondary endpoint was to look for predictors for cancer in the groups studied. Results: A cohort of 445 consecutive DM inpatients (222 DFS+ and 223 DFS-) and 255 controls were studied. Cancer prevalence in DFS+ group was significantly higher than in DFS- (p = 0.008) and controls (p = 0.031), while no differences were observed between DFS- and the controls. Univariate regression analysis showed a significant association between cancer and DFS (p = 0.007), age at admission (p ≤ 0.001), years of diabetes (p = 0.017) and haemoglobin concentration [Hb] (p = 0.030). In the multivariate regression analysis with DFS, age at admission and [Hb], only DFS (p = 0.021) and age at admission (p ≤ 0.001) persisted as independent factors associated with cancer. Conclusions: A higher prevalence of cancer in DFS+ patients than in DFS- patients and non-diabetic controls is reported. DFS and age can both be considered independent predictors of cancer in patients with DM.
RESUMEN
BACKGROUND: It is critical that interventions used to enhance the healing of chronic foot ulcers in diabetes are backed by high-quality evidence and cost-effectiveness. In previous years, the systematic review accompanying guidelines published by the International Working Group of the Diabetic Foot performed 4-yearly updates of previous searches, including trials of prospective, cross-sectional and case-control design. AIMS: Due to a need to re-evaluate older studies against newer standards of reporting and assessment of risk of bias, we performed a whole new search from conception, but limiting studies to randomised control trials only. MATERIALS AND METHODS: For this systematic review, we searched PubMed, Scopus and Web of Science databases for published studies on randomised control trials of interventions to enhance healing of diabetes-related foot ulcers. We only included trials comparing interventions to standard of care. Two independent reviewers selected articles for inclusion and assessed relevant outcomes as well as methodological quality. RESULTS: The literature search identified 22,250 articles, of which 262 were selected for full text review across 10 categories of interventions. Overall, the certainty of evidence for a majority of wound healing interventions was low or very low, with moderate evidence existing for two interventions (sucrose-octasulfate and leucocyte, platelet and fibrin patch) and low quality evidence for a further four (hyperbaric oxygen, topical oxygen, placental derived products and negative pressure wound therapy). The majority of interventions had insufficient evidence. CONCLUSION: Overall, the evidence to support any other intervention to enhance wound healing is lacking and further high-quality randomised control trials are encouraged.

Despite many improvements have been achieved, diabetic foot disease (DFD) remains a clinical, social, and economic burden. In the last years, DFD showed an evolution of its characteristics with an increase of the ischaemic/neuro-ischaemic foot in comparison to the pure neuropathic foot. Simultaneously, there was and increased incidence of concomitant cardiovascular co-morbidities, which influences the higher fragility of patients with DFS. Peripheral arterial disease (PAD) in subjects with diabetic foot seems to show a more aggressive pattern, being more distal and difficult to treat. Untreatable PAD remains the unmet need for clinicians and the main risk factor of major amputation in patients with diabetic foot ulcers. Authors aimed to describe the evolution of diabetic foot patients in the last two decades, describing also the current and future treatment which may improve outcomes in the next generations.
RESUMEN
AIMS: Principles of wound management, including debridement, wound bed preparation, and newer technologies involving alternation of wound physiology to facilitate healing, are of utmost importance when attempting to heal a chronic diabetes-related foot ulcer. However, the rising incidence and costs of diabetes-related foot ulcer management necessitate that interventions to enhance wound healing of chronic diabetes-related foot ulcers are supported by high-quality evidence of efficacy and cost effectiveness when used in conjunction with established aspects of gold-standard multidisciplinary care. This is the 2023 International Working Group on the Diabetic Foot (IWGDF) evidence-based guideline on wound healing interventions to promote healing of foot ulcers in persons with diabetes. It serves as an update of the 2019 IWGDF guideline. MATERIALS AND METHODS: We followed the GRADE approach by devising clinical questions and important outcomes in the Patient-Intervention-Control-Outcome (PICO) format, undertaking a systematic review, developing summary of judgements tables, and writing recommendations and rationale for each question. Each recommendation is based on the evidence found in the systematic review and, using the GRADE summary of judgement items, including desirable and undesirable effects, certainty of evidence, patient values, resources required, cost effectiveness, equity, feasibility, and acceptability, we formulated recommendations that were agreed by the authors and reviewed by independent experts and stakeholders. RESULTS: From the results of the systematic review and evidence-to-decision making process, we were able to make 29 separate recommendations. We made a number of conditional supportive recommendations for the use of interventions to improve healing of foot ulcers in people with diabetes. These include the use of sucrose octasulfate dressings, the use of negative pressure wound therapies for post-operative wounds, the use of placental-derived products, the use of the autologous leucocyte/platelet/fibrin patch, the use of topical oxygen therapy, and the use of hyperbaric oxygen. Although in all cases it was stressed that these should be used where best standard of care was not able to heal the wound alone and where resources were available for the interventions. CONCLUSIONS: These wound healing recommendations should support improved outcomes for people with diabetes and ulcers of the foot, and we hope that widescale implementation will follow. However, although the certainty of much of the evidence on which to base the recommendations is improving, it remains poor overall. We encourage not more, but better quality trials including those with a health economic analysis, into this area.

AIM: Anemia has been associated with severity of diabetic foot (DF) disease. Our study aimed to evaluate whether the presence of anemia could decrease the healing chances in DF. METHODS: We retrospectively analyzed all patients admitted in our department in 2021 for DF, dividing them according to presence (Group A) or absence (Group B) of anemia. Groups were compared for clinical and demographic characteristics, procedures and outcomes: healing rate (HR) at 6 months, healing time (HT) and recurrence rate (RR) at 12 months. RESULTS: We sorted out data from 196 consecutive patients: 114 (58%) in Group A and 82 (42%) in B. Group A had a higher male prevalence and a longer duration of disease. Group A showed lower hemoglobin concentration (10.3 ± 1.3 g/dL vs 13.1 ± 1.4 g/dL, p < 0.002) and red blood cells count (3.4 ± 0.5 × 106/mL vs 4.8 ± 0.6 × 106/mL, p = 0.004). Group A presented a lower HR (55.2% vs 76.8%, p = 0.0028), no differences in HT and a higher RR (23.6% vs 17.1%, p < 0.02). Cox's logistic regression on healing confirmed the negative impact of anemia: hazard ratio 2.8 (CI 95% 1.4-5.4, p = 0.0037). CONCLUSIONS: Anemia is frequent in DF and associates to a reduction in healing chances and an increase in recurrences representing an independent predictor of healing failure.

BACKGROUND: Digital subtraction angiography (DSA) still represents the gold standard for anatomical arterial mapping and revascularization decision-making in patients with chronic limb-threatening ischemia (CLTI), although DUS (Doppler Ultrasound) remains a primary non-invasive examination tool. The Global Vascular Guidelines established the importance of preoperative arterial mapping to guarantee an adequate in-line flow to the foot. The aim of this study was to evaluate the accuracy of DUS in guiding therapeutic vascular treatments on the basis of Global Vascular Guidelines without the need of a second-level examination. METHODS: Between January 2022 and June 2022, all consecutive patients with CLTI to be revascularized underwent clinical examination and DUS without further diagnostic examinations. Primary outcomes assessed were technical success, and 30-day mortality. Secondary outcomes were 1-year amputation free survival, and time between evaluation and revascularization. RESULTS: Sixty-eight patients with a mean age of 73.6 ± 8.5 years underwent lower limb revascularization. Technical success was 100%, and the 30-day mortality rate was 2.9%. Mean time between evaluation and revascularization was 29 ± 17 days. One-year amputation free survival was 97.1%. CONCLUSIONS: DUS without further diagnostic examinations can accurately assess the status of the vascular tree and foot runoff, providing enough information about target vessels to guide revascularization strategies.
RESUMEN
Despite its increasing prevalence, severity, and mortality, Diabetic foot syndrome (DFS) still remains an unaddressed critical issue. The management of DFS is adequately performed only in few centers, and clinical outcomes vary, depending on the possibility of patients to access optimal standards of care. To focus on the critical aspects of the management of DFS in Italy with the purpose of suggesting arguments that might have a more general audience, to improve the quality of therapy and accessibility to optimal care, we have written this article.
RESUMEN
BACKGROUND: Bifurcated vein grafts have been described in reconstructive microsurgery. No comparative studies have been published in lower limb arterial revascularization. The aim of this study was to compare non-reversed bifurcated vs. single vein graft in patients with critical limb-threatening ischemia (CLTI) undergoing lower limb distal bypass. METHODS: Between January 2015 and December 2021 193 CLTI patients have been treated at our center with vein bypass, and distal anastomosis on infrapopliteal vessels; 137 patients (71%) received a single graft (Group SIN), and 56 patients (29%) had a bifurcated bypass (Group BIF). Primary outcomes measures were time to healing, primary patency, primary assisted patency, secondary patency, and limb salvage. Two-year outcomes according to Kaplan-Meier curves were evaluated and compared. RESULTS: Both groups were homogeneous in terms of demographic data, preoperative risk factors, and clinical presentation except for an elderly age in Group BIF (77.5 vs. 71.5 years; P<0.001). Intraoperative technical success was achieved in all patients. Overall median duration of follow-up was 19 months (interquartile range 9-36). Wound healing did not differ between the two groups (77.4% Group SIN vs. 73.2% Group BIF; P=0.33). Mean time to healing was faster in Group BIF (2.4 vs. 6.8 months; P<0.001). At 2-year follow-up there were no differences between the two groups in terms of primary patency (71.4% Group SIN vs. 54% Group BIF; P=0.10), primary assisted patency (81.7% Group SIN vs. 76.4% Group BIF; P=0.53), secondary patency (85.1% Group SIN vs. 80.9% Group BIF; P=0.79), and limb salvage (92.3% Group SIN vs. 87.2% Group BIF; P=0.64). CONCLUSIONS: Bifurcated graft improved time to healing in CLTI patients undergoing infrapopliteal non-reversed vein bypass. Two-year overall patencies and limb salvage did not differ accordingly to vein graft configuration (single vs. bifurcated).

Necrotizing fasciitis (NF) is a rapidly progressive, life-threatening infection, involving the skin, soft tissue and fascia. We evaluated outcomes of its surgical management in diabetic foot (DF) patients in a tertiary referral centre. We retrospectively searched for NF in the database of our DF Section from 2016 to 2018. All cases were treated according to a multiprofessional integrated protocol, with Prompt Identification, Surgical debridement and systemic Antibiotic therapy (P.I.S.A. Protocol). We analysed short-term evolution (surgical procedures and major amputations), and long-term outcomes (survival and healing rates). Sixty-eight patients were referred to our DF clinic for suspicion of NF. The diagnosis was confirmed in 54 (79.4%; male/female 40/14; type 1/2 diabetes 6/48; age 62.8 ± 8.1 years; duration of diabetes 13.6 ± 10.1 years). According to the microbiological results, cases were classified as Type 1 (33-61.2%), 2 (7-12.9%) and 3 (14-25.9%). No significant differences were observed. All patients underwent a decompressive fasciotomy. Six patients (11.1%) required also a forefoot amputation and 12 (22.2%) a toe or ray amputation. No major amputation was performed in the short-term period. During the follow-up (26 ± 12â months) 46 patients (85%) healed in 94 ± 11 days. Of the remaining 8: 5 (9.2%) died for other reasons before healing, 2 (3.7%) recurred and one (1.9%) required a major amputation. Our experience reveals a relatively high prevalence of NF in DF; despite this, we observed how, when promptly and aggressively treated, NF has a good prognosis and it is not associated with an excess of limb loss and deaths.

We aimed to analyze sex-related differences in clinical outcomes among patients with diabetic foot disease (DFD) managed in a third-level referral center. We retrospectively analyzed data of admissions performed in our department between 2011 and 2015 for DFD. We collected demographic and clinical data, procedures performed during the admission, and short- and long-term outcomes in terms of healing rate and healing time, major amputation, and mortality rates during the follow-up. We focused on differences between genders and tried to figure out if sex could be considered a predictive factor. We collected data from 1237 admission performed in 842 patients (615 men [73%] and 227 women [27%]; age: 68.6 ± 27.9 years; diabetes duration: 16.4 ± 13.4 years; body mass index: 28.2 ± 6.4 kg/m2; hemoglobin A1c 7.9 ± 1.9%). Men showed a higher prevalence of comorbidities and previous ulcers or revascularization procedures. Men had a significantly higher healing rate compared with women (85.4% vs 63.2%, P < .001), but a longer healing time (124 ± 27 days vs 87 ± 14 days, P = .02). Major amputation did not differ between groups, while mortality rate was significantly higher in men (24.5% vs 16.1%, P = .02). In Cox's regression analysis, male sex was a positive predictive factor for healing and a negative one for time to heal and mortality. The difference in mortality was confirmed by a Kaplan-Meier analysis (log rank test: P = .03). DFD represents a severe disease and a strong marker of mortality affecting more severely on clinical outcomes and survival on men.

BACKGROUND: Diabetes Mellitus and obesity represent two chronic multifactorial conditions which may induce modifications in human motion strategy. Our study focused on gaining insight into biomechanical aspects of gait occurring in patients affected by both aforementioned pathologies. METHODS: One hundred subjects were recruited and divided into four groups: 25 obese-diabetic patients with peripheral neuropathy; 25 obese non-diabetic patients; 25 non-obese diabetic patients with peripheral neuropathy; 25 healthy volunteers participated as a control group. Subjects performed 3-D Gait Analysis while walking barefoot at self-selected speed, performing three consecutive trials. A multivariate analysis of variance test was used to assess spatio-temporal and kinematic data difference in the four groups. Tukey's post-hoc adjustment was applied on multiple groups' comparison. FINDINGS: Diabetic-obese subjects showed increased step width compared to controls, while step and stride length, and walking velocity were reduced. Interestingly, step width presented increased values even compared to diabetic patients. Kinematics data showed a significant reduction in ankle plantarflexion during the push-off phase of the gait cycle compared to controls, and to obese subjects. Furthermore, knee kinematics revealed a reduced peak flexion during the swing time of the gait cycle, compared to controls and diabetic subjects, which resulted in reduced knee dynamic excursion during normal walking compared to healthy subjects. INTERPRETATION: Our data demonstrated that diabetic-obese subjects present gait features typical of both such pathologies. The specific impairment of ankle and knee joint kinematics provides evidence of a synergistic effect of Diabetes Mellitus type 2 and obesity on human ambulatory function.

To test safety and efficacy of bioactive glass, a novel material used to replace bone, able to completely bond itself to the host tissues on patients treated for osteomyelitis (OM) complicating a diabetic foot (DF). We evaluated a group of patients consecutively admitted in our department between September and December 2018, who underwent surgical DF procedures for OM and in whom the use of bioactive glass could limit the demolition phase of surgical procedure. Patients were treated with bioactive glass S53P4 on top of standard treatment directly in operating room. The patients were weekly controlled for 6 months or until complete healing. During follow-up, we analyzed primarily healing rate and secondarily time of healing, need for further debridement procedures, recurrences, and adverse or hypersensitivity reactions to study treatment. Ten DF patients were enrolled (male/female 6/4; mean age 56 ± 11 years; mean duration of diabetes 10.5 ± 4.7 years, mean hemoglobin A1c 7.2 ± 0.9%). Patients underwent surgical procedure during which, after an accurate debridement, bioactive glass was applied. A healing rate of 80% in a mean time of 34 ± 2 days, with only 1 patient who needed a second surgical look, was observed. Neither recurrences nor adverse events during follow-up were observed in treated patients. This pilot experience demonstrated that bioactive glass can be considered a useful tool for the surgical treatment of DF-related OM.

OBJECTIVES: Revascularization according to the angiosome concept is of proven importance for limb salvage in chronic limb threatening ischaemia but it is not always practicable. Bifurcated bypasses could be considered as an option when an endovascular approach is not feasible or has already failed and a single bypass would not allow direct revascularization of the ischaemic area. Bifurcated bypasses are characterized by landing on two different arteries, the main artery (in direct continuity with the foot vessels) and the secondary one (perfusing the angiosome district). The aim of this study is to evaluate the safety and effectiveness of bifurcated bypass in chronic limb threatening ischaemia. METHODS: Thirty-five patients were consecutively treated with a bifurcated bypass for chronic limb threatening ischaemia from January 2014 to December 2019 in a single vascular surgery centre. Data from clinical records and operative registers were collected prospectively in an electronic database and retrospectively analysed. Primary and primary assisted bypass patency, amputation-free survival, morbidity and mortality rates at 12 and 24 months were analysed. RESULTS: Mean follow-up period was 25.1 months (range 2-72 months). Thirty-six bifurcated bypasses were performed on 35 patients (age 75.3 ± 7.2 years; 69.4% were male). According to Wound, Ischemia, foot Infection classification 22.2% belonged to stage 3 and 77.8% to stage 4 and the mean Rutherford's class was 5.1 ± 0.7. Immediate technical success was 100%. Early mortality and morbidity rates were respectively 5.5%, and 33.3%; foot surgery was performed in 50% of cases with wound healing in all patients. Primary patency and primary assisted bypass patency were 96.7% and 100% at 6 months; 85.2% and 92% at 12 months, 59.9% and 73.4% at 24 months, respectively. Amputation-free survival at 12 and 24 months was, respectively, 95.6% and 78.8%. Overall survival rates at 12 and 24 months were respectively 94.4% and 91.6%. CONCLUSIONS: Bifurcates bypass can provide good results in patients with chronic limb threatening ischaemia without endovascular option, especially in diabetic ones. Bifurcated bypass is a complex surgical solution, both to be planned and performed, and it is quite invasive for frail patients that should be accurately selected.

Plants seem to take up exogenous RNA that was artificially designed to target specific genes, followed by activation of the RNA interference (RNAi) machinery. It is, however, not known whether plants use RNAs themselves as signalling molecules in plant-to-plant communication, other than evidence that an exchange of small RNAs occurs between parasitic plants and their hosts. Exogenous RNAs from the environment, if taken up by some living organisms, can indeed induce RNAi. This phenomenon has been observed in nematodes and insects, and host Arabidopsis cells secrete exosome-like extracellular vesicles to deliver plant small RNAs into Botrytis cinerea. Here we show that micro-RNAs (miRNAs) produced by plants act as signalling molecules affecting gene expression in other, nearby plants. Exogenous miRNAs, such as miR156 and miR399, trigger RNAi via a mechanism requiring both AGO1 and RDR6. This emphasizes that the production of secondary small interfering RNAs is required. This evidence highlights the existence of a mechanism in which miRNAs represent signalling molecules that enable communication between plants.

AIM: To investigate the effectiveness of fast-track pathway (FTP) in the management of diabetic foot ulceration (DFU) after 2 years of implementation. METHODS: The study group was composed of patients who referred to a specialized DF centre due to DFUs. Those were divided in two groups: early referral (ER) and late referral (LR) patients. According to FTP, ER were considered patients who referred after 2 weeks in the case of uncomplicated non-healing ulcers (superficial, not infected, not ischemic), within 4 days in the case of complicated ulcers (ischemic, deep, mild infection) and within 24 h in the case of severely complicated ulcers (abscess, wet gangrene, fever). Healing, healing time, minor and major amputation, hospitalization, and survival were evaluated. The follow-up was 6 months. RESULTS: Two hundred patients were recruited. The mean age was 70 ± 13 years, 62.5% were male, 91% were affected by type 2 diabetes with a mean duration of 18 ± 11 years. Within the group, 79.5% had ER while 20.5% had LR. ER patients showed increased rates of healing (89.9 vs. 41.5%, p = 0.001), reduced healing time (10 vs. 16 weeks, p = 0.0002), lower rates of minor (17.6 vs. 75.6%, p < 0.0001) and major amputation (0.6 vs. 36.6%, p < 0.0001), hospitalization (47.1 vs. 82.9%, p = 0.001), and mortality (4.4 vs. 19.5%, p = 0.02) in comparison to LR. At multivariate analysis, ER was an independent predictor of healing, while LR was an independent predictor for minor and major amputation and hospitalization. CONCLUSION: After the FTP implementation, less cases of LR were reported in comparison to ER. ER was an independent predictor of positive outcomes such as healing, healing time, limb salvage, hospitalization, and survival.

BACKGROUND: We evaluated whether direct or indirect endovascular revascularization based on the angiosome model affects outcomes in type 2 diabetes and critical limb ischemia. METHODS: From 2010 to 2015, 603 patients with type 2 diabetes were admitted for critical limb ischemia and submitted to endovascular revascularization. Among these patients, 314 (52%) underwent direct and 123 (20%) indirect revascularization, depending on whether the flow to the artery directly feeding the site of ulceration, according to the angiosome model, was successfully acquired; 166 patients (28%) were judged unable to be revascularized. Outcomes were healing, major amputation, and mortality rates. RESULTS: An overall healing rate of 62.5% was observed: patients who did not receive percutaneous transluminal angioplasty presented a healing rate of 58.4% (P < .02 versus revascularized patients). A higher healing rate was observed in the direct versus the indirect group (82.4% versus 50.4%; P < .001). The major amputation rate was significantly higher in the indirect versus the direct group (9.2% versus 3.2%; P < .05). The overall mortality rate was 21.6%, and it was higher in the indirect versus the direct group (24% versus 14%; P < .05). CONCLUSIONS: These data show that direct revascularization of arteries supplying the diabetic foot ulcer site by means of the angiosome model is associated with a higher healing rate and lower risk of amputation and death compared with the indirect procedure. These results support use of the angiosome model in type 2 diabetes with critical limb ischemia.

Guillain-Barré syndrome (GBS) represents an acute inflammatory immune-mediated demyelinating polyradiculoneuropathy with an incidence of 0.6 per 100 000 people. In this article, we report the case of a 19-year-old girl affected by GBS since the age of 2 who presented at our clinic complaining for a chronic plantar hindfoot-infected ulceration. Serology showed increase of inflammatory markers and leukocytosis, and magnetic resonance imaging revealed osteomyelitis of calcaneum and soft tissue alterations with air bubbles. The patient was treated in our clinic by an integrated multidisciplinary approach consisting of immediate admission, soft tissue and bone debridement, and administration of antibiotics under the close control of infectious disease specialist. After the control of acute condition, the patient underwent negative pressure therapy associated with instillation of antiseptic solution until the restoration of bone and soft tissue loss of substance and, eventually, to the application of bioactive glass substitute until the achievement of complete wound healing.

Ultrasound (US) is a noninvasive and versatile technology that in recent years found acceptance in almost all the medical specialties, with diagnostic and interventional applications. In the diabetic foot syndrome (DFS), US found specific indications mainly in the screening, quantification, and follow-up of the vascular component of the pathology, but also in the study of the deformities and structural modifications induced by neuropathy and in the diagnosis and surgical management of infections, especially those that induce anatomical changes, like abscesses and fasciitis. This review will summarize all these application of US, giving special attention to the vascular aspects, and on the predominant role that US gained in recent times to guide the indication to revascularization, on the new standardized approach to the study of the arterial tree of the limb and the foot, the so-called duplex ultrasound arterial mapping, which significantly increased the utilization of US to plan the revascularizations in this complex pathology. Outside the vascular fields, the diagnosis of neuropathy and infection and the intraoperative use of US in the surgical management of abscesses and fasciitis will be discussed, leaving the last part to the new and interesting applications of US in the management of DFU, a field that is still in evolution, offering new possibilities to the health care professionals involved in the management of these chronic wounds. The variety of applications both in diagnostic and operative fields makes US a rather versatile technology-a toolkit-that should have a special place among those at reach of the specialists of DFS care.
