Randomized Double-blind Cost-effectiveness Comparison of Two 10% Urea Creams in Patients with Diabetic Foot Syndrome.

OBJECTIVE: To evaluate the cost-effectiveness of two 10% urea creams in patients with diabetic foot syndrome. METHODS: This was a prospective, longitudinal, single-center, randomized, double-blind, prospective clinical trial that evaluated the skin quality of 20 feet belonging to 10 patients with diabetic foot syndrome after the application of two 10% urea creams purchased from pharmacies and supermarkets. RESULTS: At follow-up, 19 (95%) of the participants' feet showed improved skin quality, irrespective of the cream applied. On visual inspection, participants had a decreased presence of xerosis, hyperkeratosis, and preulcerative signs such as subkeratotic bruising and areas of redness on the dorsum of the toes. At the 3-month follow-up, nine (90%) of the participants stated that they had continued to apply the cream as a method of self-management to prevent complications. CONCLUSIONS: Creams containing 10% urea purchased in supermarkets improve foot skin quality in patients with diabetic foot syndrome, regardless of their cost. Based on these findings, the authors recommend creams containing 10% urea as a self-management tool for patients with diabetic foot syndrome.

Are Digital Arthroplasty and Arthrodesis Useful and Safe Surgical Techniques for the Management of Patients with Diabetic Foot?

OBJECTIVE: To analyze and compare the development of short- and long-term complications in patients with diabetic foot after digital arthroplasty or arthrodesis. METHODS: The authors reviewed patient records from January 2017 to March 2020. Patients were treated by digital arthroplasty or arthrodesis to correct toe deformity (elective or prophylactic surgery), achieve ulcer healing in toes (curative surgery), or manage toe infection (emergent surgery). During 1-year follow-up, researchers registered short- and long-term complications. Researchers analyzed the association between the type of surgery and the development of short- and long-term complications. RESULTS: Forty-four patients (83.0%) received arthroplasty, and nine (17.0%) received arthrodesis. The mean time to heal from ulcers was 5.2 ± 5.2 weeks. A significant association was observed between arthrodesis and the development of long-term complications (P = .044; odds ratio, 5.1; 95% confidence interval, 0.9-27.2). No differences were observed between type of surgery and short- or long-term complications. Moreover, both short- and long-term complications were related to longer time to heal (respectively, 7.6 ± 6.0 vs 2.1 ± 0.5 weeks, P < .001; and 6.3 ± 6.2 vs 4.2 ± 4.0 weeks, P = .039). CONCLUSIONS: Digital arthroplasty or arthrodesis are good options for managing patients with diabetic foot who require digital deformity correction to achieve digital ulcer healing or management of diabetic foot infection in phalanges.

Could X-ray Predict Long-term Complications in Patients with Diabetic Foot Osteomyelitis?

OBJECTIVE: To analyze the association between radiologic changes on plain X-rays in patients with diabetic foot osteomyelitis and the development of complications at the 1-year follow-up. METHODS: A prospective, observational study was conducted involving 115 patients with diabetic foot osteomyelitis. X-ray features that were evaluated during 1-year follow-up visits included affected bone marrow, active periosteal reaction, sequestrum, cortical disruption, and other types of signs. Researchers analyzed the association between the presence of X-ray changes and complication development, such as bone or soft tissue infections, ulcer recurrence, reulceration, amputation, death, and other diabetic foot disease-related events. RESULTS: During follow-up, of 115 patients included in the study, 33 patients (28.7%) showed radiologic changes, and 85 (73.9%) developed complications. The presence of radiologic changes after ulcer healing had a significant association with complication development during the 1-year follow-up in addition to those found at different follow-up visits. Patients who showed radiologic changes had higher percentages of complications during the 1-year follow-up, and patients without radiologic changes had lower percentages of complications. CONCLUSIONS: The presence of radiologic changes is related to the development of complications in patients who suffer from diabetic foot osteomyelitis.

Topical treatment for plantar warts: A systematic review.

There are a wide variety of treatments for plantar warts, but none has been shown to be effective in all patients. We aimed to perform a systematic review of the efficacy of different topical treatments on plantar warts. Systematic electronic searches (Pubmed, Cochrane Library, Embase, and Web of Science) were conducted in April 2020. Meta-analyses, systematic reviews, and retrospective or prospective clinical trials of the effects of topical and nonsurgical treatments of plantar warts were included. Two authors performed the study selection and data extraction. Any discrepancies between the two reviewers were discussed with a third reviewer. Forty-four studies were included. The average cure rates of the most frequent treatments were variable across the studies: cryotherapy (45.61%), salicylic acid (13.6%), cantharidin-podophyllin-salicylic acid formulation (97.82%), laser (79.36%), topical antivirals (72.45%), intralesional bleomycin (83.37%), and intralesional immunotherapy (68.14%). Twenty-two studies (50%) had a level of evidence 1b and grade of recommendation A, five studies (11.4%) had a level of evidence 2b and grade of recommendation B, two studies (4.5%) had a level of evidence 3b and grade of recommendation B, and 15 studies (34,1%) with a level of evidence 4 and grade of recommendation C. First-choice treatments for common warts, such as cryotherapy and salicylic acid, have low-cure rates for plantar warts. Other treatments, such as CPA formulation, immunotherapy, and intralesional bleomycin, which have compassionate use, have higher cure rates. This review should stimulate future high-quality research to evaluate these specialized treatments.

Evolution of the TcPO2 values following hyperoxygenated fatty acids emulsion application in patients with diabetic foot disease: results of a clinical trial.

OBJECTIVE: The use of emollients to lubricate dry skin to prevent diabetic foot ulcers (DFUs), especially in neuroischaemic feet, has been recommended. This study analyses the effect of daily topical application of hyperoxygenated fatty acids emulsion on transcutaneous oxygen pressure (TcPO2) in the feet of neuropathic and neuroischaemic patients with diabetes. METHOD: Patients with diabetes and no active foot ulcer were included in this longitudinal, prospective, non-comparative clinical trial. The evolution of TcPO2 (mmHg) values after the application of the tested emulsion (Corpitol Emulsion, Laboratoires Urgo Medical, France) was evaluated for a three-month period. Modifications of skin features (skin dryness, skin shedding and skin colour) were also analysed. TcPO2 was performed using a TCM400 device (Radiometer, Denmark). RESULTS: A total of 50 patients were included in the study. Patients with neuroischaemia showed a significant increase in TcPO2 values (35.69±13.88mmHg) after two months' application of the tested emulsion that remained at month three (day 60: 42.34±10.98mmHg; p=0.006; day 90: 41.62±10.88mmHg; p=0.011). Skin dryness and shedding showed an improvement from baseline to the end of the study in both groups, secondary to the use of the tested emulsion (p<0.001 and p<0.001, respectively). Skin colour also showed differences from baseline to the final visit in the neuroischaemic patients (p=0.029). Patients with neuropathy did not show any change in skin colour from baseline to the final visit. CONCLUSIONS: Analysis of the use of the tested emulsion showed an increase in TcPO2 and an improvement in skin trophism in patients with neuroischaemic foot.

Diagnostic Accuracy of Bone Culture Versus Biopsy in Diabetic Foot Osteomyelitis.

OBJECTIVE: To compare the diagnostic accuracy of bone culture (microbiology) and biopsy (histology) in patients with acute or chronic diabetic foot osteomyelitis (DFO). METHODS: This cross-sectional study involved patients for whom providers had a clinical suspicion of DFO. Two bone samples were taken: one for microbiologic testing and another for histologic testing. The sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratio were calculated for bone culture results in relation to the probability of DFO diagnosis. RESULTS: Fifty-two patients were included; 69% had positive bone culture results, and 90.4% had positive histology results (P = .013), and of those 90.4%, 25.5% had acute and 74.5% had chronic DFO. The sensitivity of the microbiologic bone culture result was 0.70, the specificity was 0.40, the positive predictive value was 0.92, and the negative predictive value was 0.13. CONCLUSIONS: Histology provides more accurate diagnosis of DFO than microbiology, especially for patients with chronic DFO. These patients could be underdiagnosed because of false-negative results provided by bone culture. Providers should perform both tests to confirm the presence of DFO.

Role of inflammatory markers in the healing time of diabetic foot osteomyelitis treated by surgery or antibiotics.

OBJECTIVE: To analyse the predictive role of inflammatory markers in the healing time of diabetic foot osteomyelitis treated by surgery or antibiotics. METHODS: An observational study of patients with diabetic foot ulcers (DFU) and clinically suspected osteomyelitis. The patients underwent surgical or antibiotic treatment for bone infection in a specialised diabetic foot unit. Blood samples were taken from each patient to analyse biomarkers. The main outcome was the number of weeks until healing occurred. RESULTS: A total of 116 patients took part in the study. The number of weeks until healing was similar for both groups (surgical n=96 and antiobiotic n=20, treatments). No association was observed among biomarkers as predictors of time-to-healing. CONCLUSION: There is not enough evidence to define the prognostic role of inflammatory markers in the healing time of DFUs complicated with diabetic foot osteomyelitis, regardless of the treatment administered.

Correlation between Empirical Antibiotic Therapy and Bone Culture Results in Patients with Osteomyelitis.

OBJECTIVE: To analyze the correlation between empirical antibiotic therapies prescribed in primary care centers by general practitioners and the microbiology results of bone culture in patients with diabetic foot-related osteomyelitis. METHODS: This observational study involved 80 patients with diabetic foot ulcers and clinically suspected osteomyelitis. The patients were taking antibiotics prescribed by general practitioners to treat diabetic foot infections. Bone samples were taken from every patient for microbiology analysis in a specialized diabetic foot unit. MAIN OUTCOME MEASURE: The sensitivity of the bone cultures to antibiotics was compared with the patient's previous antibiotic therapy, and antibiotic and bacterial resistance were analyzed. MAIN RESULTS: The bone cultures from only 16 patients (22.3%) showed sensitivity to the antibiotics that the patient had been prescribed. Fifty-six patients (77.8%) displayed bacterial resistance to the antibiotic that they were taking. CONCLUSIONS: Awareness and implementation of international antibiotic stewardship guidelines are poor in primary care centers. It is important to establish strategies that foster a better understanding of treatment management standards and ensure the proper implementation of guidelines.

Digital Deformity Assessment Prior to Percutaneous Flexor Tenotomy for Managing Diabetic Foot Ulcers on the Toes.

The aim of this study is to evaluate the prevalence of digital deformities in patients with diabetes mellitus according to the McGlamry classification and relate the types of digital deformities with the history of digital ulcer. A cross-sectional study was performed in the diabetic foot unit between September 2016 and September 2017. All consecutive patients were classified by digital deformities according to the McGlamry classification (flexor stabilization, flexor substitution, and extensor substitution) using slow-motion videos. In all patients, the Foot Posture Index 6 was performed and previous toe ulceration, toe calluses, and nail dystrophy were evaluated. A total of 142 feet were evaluated, in which 29 (20.27%) feet did not show dynamic deformities, 65 (57.5%) were classified as flexor stabilization, 9 (8%) as flexor substitution, and 39 (34.5%) as extensor substitution. In total, 23% the feet with previous ulcer were classified as extensor substitution. A previous toe ulcer on the tip (p = .033; confidence interval [CI] 1.06 to 4.99; odds ratio [OR] 2.3), pronated foot according to the Foot Posture Index 6 (p = .048; 95% CI 0.9 to 8.9; OR 2.9), and callus on the tip (p = .002; 95% CI 1.47 to 6.41; OR 3.07) were associated with flexor stabilization deformities. Flexor stabilization, associated with the pronated foot, was the most prevalent dynamic deformity. Extensor substitution was present in approximately 40% of the patients and in 20% of the patients with previous ulcer, in whom flexor tenotomy could aggravate the digital deformity. An evaluation of dynamic deformities during gait should be included as a presurgical assessment to achieve successful surgical results.

Complications associated with the approach to metatarsal head resection in diabetic foot osteomyelitis.

The aim of this study was to evaluate the recovery time and the development of complications in the dorsal and plantar approach to metatarsal head resections (MHR) in patients with diabetic foot ulcers complicated by osteomyelitis. A retrospective study was carried out involving 108 patients who underwent MHRs for the treatment of diabetic foot osteomyelitis. Two cohorts were defined: dorsal approach with incision closed with sutures and plantar approach with ulcer healed using conservative treatment. The main outcomes were the weeks until healing and complications related to the approaches. Fifty-three patients (49.1%) underwent a plantar approach and 55 (50.9%) a dorsal approach. Both approaches rendered similar healing times. However, the patients undergoing a dorsal approach developed more post-surgical complications than patients treated through a plantar approach. The dorsal approach intervention was performed on smaller and shallower ulcers; however, more complications developed at follow up using this approach than through a plantar approach for MHR complicated with osteomyelitis.

Is pharmacologic treatment better than neural mobilization for cervicobrachial pain? A randomized clinical trial.

Purpose: This study aim was to compare the effectiveness of the median nerve neural mobilization (MNNM) and cervical lateral glide (CLG) intervention versus oral ibuprofen (OI) in subjects who suffer cervicobrachial pain (CP). Methods: This investigation was a, multicenter, blinded, randomized controlled clinical trial (NCT02595294; NCT02593721). A number of 105 individuals diagnosed with CP were enrolled in the study and treated in 2 different medical facilities from July to November 2015. Participants were recruited and randomly assigned into 3 groups of 35 subjects. Intervention groups received MNNM or CLG neurodynamic treatments, and the (active treatment) control group received an OI treatment for 6 weeks. Primary outcome was pain intensity reported through the Numeric Rating Scale for Pain (NRSP). Secondary outcomes were physical function involving the affected upper limb using the Quick DASH scale, and ipsilateral cervical rotation (ICR) using a cervical range of motion (CROM) device. Assessments were performed before and 1 hour after treatment for NRSP (baseline, 3 and 6 weeks) and CROM (baseline and 6 weeks), as well as only 1 assessment for Quick DASH (baseline and 6 weeks). Results: Repeated-measures ANOVA intergroup statistically significant differences were shown for CP intensity (F(2,72) = 22.343; P < .001; Eta2 = 0.383) and Quick DASH (F(2,72) = 15.338; P < .001; Eta2 = 0.299), although not for CROM (F(2,72) = 1.434; P = .245; Eta2 = 0.038). Indeed, Bonferroni´s correction showed statistically significant differences for CP intensity (P < .01; 95% CI = 0.22 - 3.26) and Quick DASH reduction (P < .01; 95% CI = 8.48 - 24.67) in favor of the OI treatment at all measurement moments after baseline. Conclusions: OI pharmacologic treatment may reduce pain intensity and disability with respect to neural mobilization (MNNM and CLG) in patients with CP during six weeks. Nevertheless, the non-existence of between-groups ROM differences and possible OI adverse effects should be considered.

Effects of Median Nerve Neural Mobilization in Treating Cervicobrachial Pain: A Randomized Waiting List-Controlled Clinical Trial.

BACKGROUND: There is a current lack of sufficiently high-quality randomized controlled clinical trials that measure the effectiveness of neural tissue mobilization techniques such as median nerve neural mobilization (MNNM) and their specific effects on cervicobrachial pain (CP). The aim of this study was to compare the effectiveness of MNNM in subjects with CP vs. a waiting list control group (WLCG). METHODS: A single-blinded, parallel, randomized controlled clinical trial was performed (NCT02596815). Subjects were recruited with a medical diagnosis of CP corroborated by magnetic resonance imaging. In total, 156 individuals were screened, 60 subjects were recruited, and 51 completed the trial. Pain intensity reported using the Numeric Rating Scale for Pain (NRSP; primary outcome), cervical range of motion (CROM), and functionality using the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scale were the outcome measurements. Assessments were conducted at baseline and 1 hour after treatment (intervention days 1, 15, and 30). Therefore, MNNM was implemented with 30 days of follow-up. RESULTS: The NRSP values of the MNNM group were significantly (P < 0.0001; 95% confidence interval [CI]) superior to those obtained in the WLCG. Subjects treated with MNNM reported an NRSP decrease of 3.08 points at discharge. CROM and QuickDASH outcome values were significantly (P ˂ 0.0001; 95% CI) improved only in the MNNM group. Hedges' g showed a very large effect of the MNNM intervention. CONCLUSION: MNNM may be superior to no treatment in reducing pain and increasing function in the affected upper limbs of subjects with CP.

Cervical Lateral Glide Neural Mobilization Is Effective in Treating Cervicobrachial Pain: A Randomized Waiting List Controlled Clinical Trial.

BACKGROUND: Cervicobrachial pain (CP) is a high-incidence and prevalent condition. Cervical lateral glide (CLG) is a firstline treatment of CP. There is a current lack of enough high-quality randomized controlled double-blind clinical trials that measure the effectiveness of neural tissue mobilization techniques such as the CLG and its specific effect over CP. OBJECTIVES: The aim of the present study was to assess the effect of CLG neural mobilization in treating subjects who suffer from CP, compared with the complete absence of treatment. STUDY DESIGN: This investigation was a single-center, blinded, parallel randomized controlled clinical trial (RCT). SETTING: One hundred forty-seven individuals were screened in a medical center from July to November 2015. Fifty-eight participants were diagnosed with CP. METHODS: Participants were recruited and randomly assigned into two groups of 29 subjects. The intervention group received CLG treatment, and the control group (CG) was assigned to a six-week waiting list to receive treatment. Randomization was carried out by concealed computer software randomized printed cards. The primary outcome was pain intensity, reported through the Numeric Rating Scale for Pain (NRSP). Secondary outcomes were physical function involving the affected upper limb using the Quick DASH scale and ipsilateral cervical rotation (ICR) using a CROM device. Assessments were made at baseline and one hour after treatment. RESULTS: The CLG group NRSP mean value was significantly (P < 0.0001) superior to those obtained by the CG. Subjects treated with CLG reported an average NRSP decrease of 2.16 points (35%). CROM device and Quick DASH outcome values also reported significant (P < 0.0001) improvements only in the CLG group. Cohen's d showed a very large effect of the CLG intervention at subject discharge. LIMITATIONS: Due to the lack of dipper subgroup analysis and additional reproductions of the applied protocol, the authors considered the generalization of the study results to be impossible. CONCLUSIONS: CLG is superior to the absence of treatment in reducing pain and increasing the affected upper limb function of subjects who suffer from CP. CLG may be considered an effective treatment in specific cases of CP.

Comparison of Pressure Pain Thresholds in Upper Trapezius and Temporalis Muscles Trigger Points Between Tension Type Headache and Healthy Participants: A Case-Control Study.

OBJECTIVE: To date, the minimum clinical differences (MCDs) in the pressure pain thresholds (PPTs) of the upper trapezius and temporalis muscles have not yet been established in participants with tension-type headache (TTH). The purpose of the study was to evaluate the MCDs of the PPTs of the upper trapezius and temporalis in participants with TTH and those without TTH. METHODS: The sample comprised 120 participants with TTH (n = 60; mean [standard deviation] years = 38.30 [10.05]) and without TTH (n = 60; 34 [8.20]). The participants were recruited from an outpatient clinic in Spain from 2014 to 2016. The PPTs of the most hyperalgesic trigger points of the upper trapezius and temporalis were assessed. RESULTS: There were statistically significant differences, mean (standard deviation) kg/cm2, for the right upper trapezius PPT (P < .001; 1.52 [0.35] vs 2.37 [0.49]), the left upper trapezius PPT (P < .001; 1.53 [0.36] vs 2.29 [0.49]), the right temporalis PPT (P = .008; 1.56 [0.31] vs 1.72 [0.33]), and the left temporalis PPT (P = .001; 1.57 [0.27] vs 1.74 [0.30]) between participants with and without TTH, respectively. CONCLUSIONS: The PPT MCDs for the right and left upper trapezius and the right and left temporalis were 0.85, 0.76, 0.16, and 0.17 kg/cm2, respectively, for the clinical management of trigger points in participants with TTH.

Validation of an algorithm to predict reulceration in amputation patients with diabetes.

The aim of this article was to assess the ability to predict reulceration in people with diabetes and a history of minor amputation according to the formula proposed by Miller et al. A retrospective study was performed on 156 consecutive records of patients with a recent history of simple or multiple forefoot amputation. The sample was divided according to Miller's formula into patients at low risk of reulceration and those at high risk; those were further divided into two subgroups according to whether or not the first segment of the forefoot had been amputated. Forty-eight (47·1%) individuals suffered forefoot reulceration, showing a median reulceration-free survival time of 8 months [interquartile range (IR) 3·6-14·8]. Nephropathy (P = 0.005) and Miller's formula (P = 0.028) were risk factors for reulceration-free survival time in the univariate analysis. The pattern relating to the first segment amputated [hazard ratio (HR) 2·853; P = 0·004; 95% confidence interval (CI) 1·391-5·849] and nephropathy (HR 2·468; P = 0.004; 95% CI 1.328-4.587) showed a significant hazard ratio in the multivariate Cox model. Participants with first segment amputation and one other amputation showed an association with the probability of reulceration in comparison with any other specific type of minor amputation.

Review and Evaluation of European National Clinical Practice Guidelines for the Treatment and Management of Active Charcot Neuro-Osteoarthropathy in Diabetes Using the AGREE-II Tool Identifies an Absence of Evidence-Based Recommendations.

Background: Charcot neuro-osteoarthropathy (CNO) is a rare but devastating complication of diabetes associated with high rates of morbidity; yet, many nonfoot specialists are unaware of it, resulting in missed and delayed diagnosis. Clinical practice guidelines (CPGs) have proven useful in improving quality of care and standardizing practice in diabetes and diabetic foot care. However, little is known about the consistency in recommendations for identification and management of active CNO. Aim: The aim of this study is to review European national diabetes CPGs for the diagnosis and management of active CNO and to assess their methodological rigor and transparency. Methods: A systematic search was performed to identify diabetes national CPGs across Europe. Guidelines in any language were reviewed to explore whether they provided a definition for active CNO and recommendations for diagnosis, monitoring, and management. Methodological rigor and transparency were assessed using the Appraisal of Guidelines for Research and Evaluation (AGREE-II) tool, which comprises 23 key items organized within six domains with an overall guideline assessment score of ≥ 60% considered to be of adequate quality to recommend use. Each guideline was assessed by two reviewers, and inter-rater agreement (Kendall's W) was calculated for AGREE-II scores. Results: Seventeen CPGs met the inclusion criteria. Breadth of CNO content varied across guidelines (median (IQR) word count: 327; Q1 = 151; Q3 = 790), and 53% provided a definition for active CNO. Recommendations for diagnosis and monitoring were provided by 82% and 53%, respectively, with offloading being the most common management recommendation (88%). Four guidelines (24%) reached threshold for recommendation for use in clinical practice (≥ 60%) with the scope and purpose domain scoring highest (mean (SD): 67%, ± 23%). The remaining domains had average scores ranging between 19% and 53%. Inter-rater agreement was strong (W = 0.882; p < 0.001). Conclusions: European national CPGs for diabetes provide limited recommendations on active CNO. All guidelines showcased deficits in their methodology, suggesting that more rigorous methods should be employed for diabetes CPG development across Europe.

Punch Grafting for the Management of Hard-to-Heal Diabetic Foot Ulcers: A Prospective Case Series.

Punch grafting is an alternative treatment to enhance wound healing which has been associated with promising clinical outcomes in various leg and foot wound types. We aimed to evaluate the clinical outcomes of punch grafting as a treatment for hard-to-heal diabetic foot ulcers (DFUs). Six patients with chronic neuropathic or neuroischemic DFUs with more than 6 months of evolution not responding to conventional treatment were included in a prospective case series between May 2017 and December 2020. All patients were previously debrided using an ultrasound-assisted wound debridement and then, grafted with 4 to 6 mm punch from the donor site that was in all cases the anterolateral aspect of the thigh. All patients were followed up weekly until wound healing. Four (66.7%) DFUs were located in the heel, 1 (16.7%) in the dorsal aspect of the foot and 1 (16.7%) in the Achilles tendon. The median evolution time was 172 (interquartile range [IQR], 25th-75th; 44-276) weeks with a median area of 5.9 (IQR; 1.87-37.12) cm2 before grafting. Complete epithelization was achieved in 3 (50%) patients at 12 weeks follow-up period with a mean time of 5.67 ± 2.88 weeks. Two of the remaining patients achieved wound healing at 32 and 24 weeks, respectively, and 1 patient showed punch graft unsuccessful in adhering. The median time of wound healing of all patients included in the study was 9.00 (IQR; 4.00-28.00) weeks. The wound area reduction (WAR) at 4 weeks was 38.66% and WAR at 12 weeks was 88.56%. No adverse effects related to the ulcer were registered through the follow-up period. Autologous punch graft is an easy procedure that promotes healing, achieving wound closure in chronic DFUs representing an alternative of treatment for hard-to-heal DFUs in which conservative treatment has been unsuccessful.

Effectiveness of Off-Loading Devices in Patients With Active Diabetic Foot Ulcer: A Systematic Review.

A systematic review of the effectiveness of off-loading in the diabetic foot was done. Searches were conducted in October 2022 using the PubMed and Scielo databases. Randomized clinical trials or controlled clinical trials were included. Two authors performed the study selection and data extraction, and any discrepancies between the 2 reviewers were resolved through discussion with a third reviewer. Fourteen papers met the selection criteria with 822 patients included, but the sample sizes in all studies were small. Most of the published studies were done in European countries. Total contact cast was the most effective off-loading. The present review studies the effectiveness of off-loading systems in patients with diabetic foot ulcer, as well as different off-loading methods, with total contact cast proving to be the gold standard, despite its adverse effects.

Variables That Could Influence Healing Time in Patients with Diabetic Foot Osteomyelitis.

AIM: To compare the healing time in patients with diabetic foot osteomyelitis according to the presence or absence of clinical signs of infection, variation of blood parameters, the presence of different radiological signs, and the treatment received for the management of osteomyelitis. METHODS: A prospective observational study was carried out in a specialised Diabetic Foot Unit between November 2014 and November 2018. A total of 116 patients with osteomyelitis were included in the study (treated by either a surgical or medical approach). During the baseline visit, we assessed the diagnosis of osteomyelitis, demographic characteristics and medical history, vascular and neurological examination, clinical signs of infection, increased blood parameters, radiological signs of osteomyelitis, and the treatment to manage osteomyelitis. We analysed the association between the presence of clinical signs of infection, variation of blood parameters, presence of radiological signs, and treatment received for management of osteomyelitis with the healing time. RESULTS: The mean time to ulcer healing was 15.8 ± 9.7 weeks. Concerning healing times, we did not find an association with the presence of clinical signs of infection or with the increase in blood parameters, except in the case of eosinophils, which with higher values appear to increase the healing time (U = 66, z = -2.880, p = 0.004). Likewise, no relationship has been found between healing time and the appearance of the different radiological signs of osteomyelitis, nor depending on the treatment administered for the management of osteomyelitis. CONCLUSION: High levels of eosinophils are associated with a longer healing time of diabetic foot ulcers complicated with osteomyelitis, finding no other factors related to increased healing time.
