Introducción: Los diabéticos muestran una disminuida función del sistema inmune. Su complicación más temida es la aparición de las úlceras del pie. El Heberprot-P® tiene efectos beneficiosos en la curación de estas úlceras. Objetivo: Evaluar el efecto de la inmunidad celular en el tratamiento de las úlceras del pie diabético con Heberprot-P®. Métodos: Se realizó un estudio observacional, prospectivo, de serie de casos, en 30 pacientes con úlcera de pie diabético, ingresados en el Instituto Nacional de Angiología y Cirugía Vascular. Se administraron 75 µg de Heberprot-P®, tres veces por semana, a través de vías peri- e intralesional, durante ocho semanas. Se evaluaron las variables edad, sexo, glucemia en ayunas, creatinina, urea, ácido úrico, prueba de hipersensibilidad retardada, porcentaje de granulación, tiempo de cierre de la lesión y localización de la úlcera, antes de comenzar el tratamiento, a las 4 y 8 semanas. Resultados: Se precisó un predominio del 60 por ciento en el sexo femenino y del color de piel blanca. Los niveles de glucemia y creatinina se comportaron más elevados en los anérgicos; la urea fue similar tanto en anérgicos como en reactivos; y el ácido úrico resultó mayor en hombres reactivos y en mujeres anérgicas. Hubo mayor proporción de reactivos (63,6 por ciento), que en la cuarta semana presentaron un tejido de granulación igual o mayor al 50 por ciento; y a la octava, igual o mayor al 70 por ciento. Conclusiones: La condición en los pacientes diabéticos de ser reactivo a las pruebas de hipersensibilidad retardada con úlcera de pie diabético de tipo neuropática, tratados con Heberprot-P®, está asociada directamente con una mejor respuesta en la cicatrización de sus lesiones, mediante la formación del tejido de granulación, que favorece el cierre total o parcial de la lesión. Esto no ocurrió con los pacientes anérgicos a dicha prueba(AU)
Introduction: Diabetics show decreased immune system function. Its most feared complication is the appearance of foot ulcers. Heberprot-P® has beneficial effects in healing these ulcers. Objective: To assess the effect of cellular immunity in the treatment of diabetic foot ulcers with Heberprot-P®. Methods: An observational, prospective, case series study was conducted in 30 patients with diabetic foot ulcer admitted to the National Institute of Angiology and Vascular Surgery. 75 µg of Heberprot-P®, three times a week, were administered through peri- and intralesional routes, during eight weeks. The variables age, sex, fasting blood glucose, creatinine, urea, uric acid, delayed hypersensitivity test, percentage of granulation, time of closure of the lesion and location of the ulcer, before starting treatment, at 4 and 8 weeks were evaluated. Results: A predominance of 60 % in females and white skin color were specified. Blood glucose and creatinine levels behaved higher in the anergics; urea was similar in both anergics and reagents; and uric acid was higher in reactive men and anergic women. There was a higher proportion of reagents (63.6 por ciento), which in the fourth week presented a granulation tissue equal to or greater than 50 por ciento; and at the eighth week, it was equal to or greater than 70 por ciento. Conclusions: The condition of being reactive to delayed hypersensitivity tests in diabetic patients with diabetic foot ulcer of neuropathic type, treated with Heberprot-P® is directly associated with a better response in the healing of their lesions, through the formation of granulation tissue, which favors the total or partial closure of the lesion. This did not occur with patients who were anergic to this test(AU)

Abstract Objectives: This study aimed to explore the effects of bone marrow-derived Mesenchymal Stem Cell-Conditioned Medium (MSC-CM) treating diabetic foot ulcers in rats. Methods: Models of T2DM rats were induced by a high-fat diet and intraperitoneal injection of STZ in SD rats. Models of Diabetic Foot Ulcers (DFUs) were made by operation on hind limbs in diabetic rats. Rats were divided into four groups (n = 6 for each group), i.e., Normal Control group (NC), Diabetes Control group (DM-C), MSC-CM group and Mesenchymal Stem Cells group (MSCs). MSC-CM group was treated with an injection of conditioned medium derived from preconditioned rats' bone marrow MSCs around ulcers. MSCs group were treated with an injection of rats' bone marrow MSCs. The other two groups were treated with an injection of PBS. After the treatment, wound closure, re-epithelialization (thickness of the stratum granulosums of the skin, by H&E staining), cell proliferation (Ki67, by IHC), angiogenesis (CD31, by IFC), autophagy (LC3B, by IFC and WB; autoly-sosome, by EM) and pyroptosis (IL-1β, NLRP3, Caspase-1, GSDMD and GSDMD-N, by WB) in ulcers were evaluated. Results: After the treatment wound area rate, IL-1β by ELISA, and IL-1β, Caspase-1, GSDMD and GSDMD-N by WB of MSC-CM group were less than those of DM group. The thickness of the stratum granulosums of the skin, proliferation index of Ki67, mean optic density of CD31 and LC3B by IFC, and LC3B by WB of MSC-CM group were more than those of DM group. The present analysis demonstrated that the injection of MSC-CM into rats with DFUs enhanced the wound-healing process by accelerating wound closure, promoting cell proliferation and angiogenesis, enhancing cell autophagy, and reducing cell pyroptosis in ulcers. Conclusions: Studies conducted indicate that MSC-CM administration could be a novel cell-free therapeutic approach to treat DFUs accelerating the wound healing process and avoiding the risk of living cells therapy.
ABSTRACT
ABSTRACT BACKGROUND: Ulceration of the feet in patients with diabetes is a frequent complication that increases morbidity, mortality, hospitalization, treatment costs, and non-traumatic amputations. OBJECTIVE: To present a systematic review of the treatment of patients with diabetes mellitus and infected foot ulcers using photodynamic therapy. DESIGN AND SETTING: A systematic review was performed in the postgraduate program in nursing at the Universidade da Integração Internacional da Lusofonia Afro-Brasileira, Ceará, Brazil. METHODS: PubMed, CINAHL, Web of Science, EMBASE, Cochrane Library, Scopus, and LILACS databases were screened. The methodological quality, risk of bias, and quality of evidence of each study were assessed. Review Manager was used for the meta-analysis. RESULTS: Four studies were included. They highlighted significantly better outcomes in patient groups treated with photodynamic therapy than those in the control groups that were treated with topical collagenase and chloramphenicol (P = 0.036), absorbent (P < 0.001), or dry covers (P = 0.002). Significant improvements were noted in terms of the microbial load in the ulcers and tissue repair, with a reported reduction in the need for amputation by up to 35 times. Photodynamic therapy resulted in significantly better outcomes between the experimental and control groups (P = 0.04). CONCLUSION: Photodynamic therapy is significantly more effective in treating infected foot ulcers than standard therapies.

This study aims to determine the topical effect of aloe vera in healing diabetic foot ulcers. Methods: This research is a systematic completion that will use six databases (CINAHL, Academic, PubMed, ProQuest, ScienceDirect, SpringerLink, and google scholar) to search for randomized controlled trial and Quasi-Experimental articles randomly in 2007-2022. The Systematic Review protocol used follows PRISMA as a guide in preparing insights and The Joanna Briggs Institute (JBI) Critical Appraisal Tools to assess research quality. This study will determine the effect of topical aloe vera on wound healing in diabetic foot ulcers. Discussion: The results of this study can be useful for knowing the topical effects of aloe vera for wound healing in diabetic foot ulcers. Trial Registration: This protocol has been registered on the protocol registration site for systematic review namely PROSPERO with registration number CRD42022318695.
ABSTRACT
Objective:To observe the effect of supplementing vacuum sealing drainage with hyperbaric oxygen in the short term treatment of diabetic foot ulcers.Methods:A total of 156 persons diagnosed with diabetic foot ulcers were randomly divided into a control group and a treatment group, each of 78. Both groups received life guidance and active treatment to lower blood sugar and lipids, as well as anti-infection treatment guided by bacterial cultures. Both groups′ wounds were debrided. The wound was then covered with foam, sealed, and negative pressure of -75 to -100mmHg was applied during 1 week of drainage. Two courses of this treatment were applied. In addition, the treatment group received hyperbaric oxygen daily during the two weeks. The exposure pressure was incrased to 0.25MPa over 15min with 100% oxygen. That was inhaled in two 30min sessions with a 10min interval. The pressure then decompressed at a constant rate for 25 minutes. Wound healing, hemorheology, wound granulation tissue staining and any changes in TGF-β1 were observed before as well as after 7 and 14 days of the treatment.Results:The average wound size and symptom score of both groups had improved significantly after the treatment, with the largest effect in the treatment group during the first week. Both groups′ hemorheology had improved significantly after one week, but the treatment group′s improvement was greater. After 2 weeks, however, there was no significant difference in the average hemorheologic indicators for either group compared with before the treatment. Hematoxylin-eosin staining of the wound tissues showed that there were many inflamed cells before the treatment, with relatively little fresh granulation tissue or new blood vessels. After one week of treatment much new granulation tissue was observed under the microscope in both groups, with no significant difference between them. One week later, there was still much granulation tissue in the control group, but slightly less in the treatment group. The ave-rage post-treatment TGF-β1 protein levels in the wound tissues of both groups were significantly higher than before the treatment, but after two weeks the average TGF-β1 protein level had decreased significantly in the treatment group compared with the control group.Conclusions:One week of hyperbaric oxygen treatment can effectively improve the hemorheology of persons with diabetic foot ulcers, promote the proliferation of granulation tissue and fibroblasts, and increase the level of TGF-β1 protein in the wound tissues. However, the effects of hyperbaric oxygen treatment weaken gradually with time.
ABSTRACT
OBJECTIVES@#The measurement of diabetic foot ulcers is important for the success in diabetic foot ulcer management. At present, it lacks the accurate and convenient measurement tools in clinical. In recent years, artificial intelligence technology has demonstrated the potential application value in the field of image segmentation and recognition. This study aims to construct an intelligent measurement model of diabetic foot ulcers based on the deep learning method, and to conduct preliminary verification.@*METHODS@#The data of 1 042 diabetic foot ulcers clinical samples were collected. The ulcers and color areas were manually labeled, of which 782 were used as the training data set and 260 as the test data set. The Mask RCNN ulcer tissue color semantic segmentation and RetinaNet scale digital scale target detection were used to build a model. The training data set was input into the model and iterated. The test data set was used to verify the intelligent measurement model.@*RESULTS@#This study established an intelligent measurement model of diabetic foot ulcers based on deep learning. The mean average precision@.5 intersection over union (mAP@.5IOU) of the color region segmentation in the training set and the test set were 87.9% and 63.9%, respectively; the mAP@.5IOU of the ruler scale digital detection in the training set and the test set were 96.5% and 83.4%, respectively. Compared with the manual measurement result of the test sample, the average error of the intelligent measurement result was about 3 mm.@*CONCLUSIONS@#The intelligent measurement model has good accuracy and robustness in measuring the diabetic foot ulcers. Future research can further optimize the model with larger-scale data samples.

Background: Diabetic foot ulcers (DFU) are debilitating to the patients and significantly impair their quality of life. DFU associated with infection have the worst outcomes and may lead to amputations if timely intervention is not done. In the present study, aim was to identify the association between the type of organism isolated and the rates of amputations in diabetic foot ulcers.Methods: We retrospectively studied 50 diabetic foot ulcers from January 2017 to June 2017, who were in-patients in a single unit of surgery department in King George Hospital, Visakhapatnam. Baseline clinical examination was done. Parameters such as age, sex, duration, diabetic status and its treatment, organisms isolated, various treatment options for ulcers and the outcomes were studies.Results: Males were the predominant study subjects (M: F=32:18). The age of presentation was 18-65 years with an average of 46 years. Gram negative organisms were the frequent microbial isolates, all being mono-microbial infections. It was dominated by E. coli (17), Pseudomonas (12) and Klebsiella (11). Above-knee amputation was done in one patient and below-knee amputations in three patients. Total mortality in our study was 5. After applying the chi-square test, it was found that there is no significant association between the type of organism and the rate of amputations in our study.Conclusions: Diabetes is a significant risk factor for ulceration in the extremities, which possesses considerable mortality and morbidity. Early intervention, control of diabetes and compliance of the patient treatment are all necessary to reduce the rates of amputations and mortality in patients with diabetic foot ulcers.
ABSTRACT
Background: The present study was conducted to determine the association of sociodemographic parameters, comorbid conditions and complications of diabetes mellitus (DM) with the treatment outcomes of diabetic foot ulcers.Methods: The present prospective observational study enrolled 105 participants aged 30-85 years with diabetic foot ulcers presenting to general surgery department during a period of 18 months. Participants who were terminally ill, who had trophic ulcers of Hansen’s disease and filariasis and its sequelae were excluded. The study was approved by institutional ethics committee and written informed consent was obtained from all study participants. Data was analyzed using R and the test of significance was chi square test, p<0.05 was considered statistically significant.Results: Higher proportion of male participants and those aged between 50-69 years were encountered. Male participants were of higher age and the mean duration of DM in participants with diabetic foot ulcer was 8 years. The mean HbA1C of study participants was 8.1%, 38.1% participants had high plasma glucose. Food deformity was observed in 41% participants. 62.9% and 66.7% participants had diabetic peripheral neuropathy and peripheral arterial disease respectively. The mean time required for healing among participants with diabetic foot ulcers was 45.8 Significant association of major amputation with diabetic peripheral neuropathy (p=0.02), Wagner’s grading (p<0.001) and peripheral arterial disease (PAD) (p=0.006) was observed.Conclusions: The presence of diabetic peripheral neuropathy and PAD were risk factors for major amputations in diabetic foot ulcers. Lower Wagner’s grading was associated with lower chances of major amputation.
ABSTRACT
Background: The study was conducted to determine the diagnostic accuracy of ankle branchial pressure index (ABPI) in predicting major amputation and duration of wound healing in diabetic foot ulcers.Methods: 105 participants (30-85 years) admitted in general surgery inpatient with diabetic foot ulcers during 18 months were enrolled in the present prospective observational study. Institutional ethics committee approved the study and written informed consent was obtained from all study participants. Data was analyzed using R and the tests of significance were chi square test and ANOVA. Area under curve (AUC) of receiver operator characteristic (ROC) was used to describe the diagnostic accuracy of ABPI. P<0.05 was considered statistically significant.Results: The mean ABPI of study participants was 0.7 with 23.8% participants having normal ABPI. Lower ABPI was associated with longer duration of ulcer healing (p=0.003). All participants with ABPI <0.3 required more than 120 days for wound healing (p<0.001) and required above knee amputation (p<0.001). AUC ROC of ABPI and major amputation is 0.987 with 92.9% sensitivity and 98.9% specificity. Significantly higher proportion of participants with ABPI ≤0.48 underwent major amputation. The AUC of ROC of ABPI on duration of wound healing was 0.953 with 84.9% sensitivity and 98.1% specificity. Conclusions: ABPI can be used as a routine tool in all patients with diabetic foot ulcers for screening peripheral arterial disease so that the decision for amputation can be made early during diabetic foot ulcers.
ABSTRACT
Introduction: Diabetic foot ulcer is a major disablingcomplication of Diabetes Mellitus and often precedes lowerextremity amputation. This study aims to evaluate the level ofHbA1c and lipid profile in patients with diabetic foot ulcer asT2DM patients areprone to diabetic dyslipidemia,which puts them at risk ofdeveloping macrovascular and microvascular diseases.Material and methods: The study was accomplished at atertiary care hospital in Jammu & Kashmir. One hundred tensubjects with T2DM were enrolled for the present study, thisincluded 55 subjects with DFU and 55 subjects without DFU.The HbA1c and lipid profile of the subjects were measuredwith standard methods.Results: In our study HbA1c level was found higher indiabetic patients with diabetic foot ulcer when compared withpatients without. Also lipid profile was found deranged indiabetic foot ulcer patients in comparison to control group. Itwas found that approximately 78% DFU have HbA1c levels˃7%. Unlike the DFU-patients, 79% of patients without DFUhave HbA1c level controlled.Conclusion: As diabetic foot ulcer is a major disablingcomplication of Diabetes Mellitus and often precedes lowerextremity amputation, we conclude that HbA1c level shouldbe maintained in normal range and regulating it is imperativefor avoiding T2DM complications.
ABSTRACT
Background: The incidence of diabetes and its complications is rising as a result of the lifestyle changes. The foot is most frequent site for complication in patients with diabetes. Dressings have a vital part to play in the management of wounds. The ideal antiseptic is one that is lethal to all forms of bacteria, has no deleterious effect on healing tissues, delineates the operative areas, easily applied and has wide spectrum of activity and absence of acquired bacterial resistance. Nanotechnology makes it possible to expand the surface area of silver particles markedly to nanoscale. They expand the surface area of silver particles increasing their contact with bacteria.Methods: In the proposed study, over a period of 18 months, 60 cases (30-30 in 2 groups) of diabetic foot ulcers were studied with respect to response (healing) to nano silver dressing and betadine dressing after dividing them randomly. Assessment was based on various parameters like size reduction, healthy granulation tissue, etc.Results: It was seen that percentage reduction in size, was more in nano silver group as compared to betadine group. Wounds were managed successfully, early in nano silver group and wound healing was better in nano silver group as compared to betadine group. Also, nano silver was better antimicrobial.Conclusions: The prospective study showed nano silver gel is safe and effective in wound management and gives better efficacy and faster response as compared to traditional betadine dressing.
ABSTRACT
Background: The objective of the study is to find out the effect of honey dressing versus povidone iodine dressing for reduction of wound size in diabetic foot ulcer.Methods: This randomized controlled trial was done in the Department of General Surgery, KLES Dr. Prabhakar Kore Hospital, Belagavi from January 2017 to December 2017. 64 patients were randomized into 32 group each undergoing unprocessed honey dressing and other group undergoing povidone iodine dressing.Results: The mean wound size in honey dressing was 23.16 cm2 and 23.03 cm2 in povidone dressings at baseline, 23.16 cm2 and 22.94 cm2 at 1st day follow up, 23.16 cm2 and 22.94 cm2 at 3rd day follow up, 19.38 cm2 and 20.28 cm2 at 5th day follow up, 16.13 cm2 and 17.06 cm2 at 7th day follow up, 12.44 cm2 and 16.13 cm2 at 10th day follow up and the end of 15th day, it was 10.69 cm2 and 15.06 cm2 respectively in honey dressing group and povidone dressing group. The difference in the wound size in honey dressing group and povidone dressing group at 1st day, 3rd day, 5th day, 7th day, 10th day follow up period were statistically not significant (p>0.05). The difference in the wound size in honey dressing group at 15th day follow up period were statistically significant (p<0.05).Conclusions: This study shows more favorable results with honey dressing for reduction of wound size in diabetic foot ulcers.
ABSTRACT
Background: Diabetes mellitus has become a global epidemic. Mortality and morbidity due to this is increasing in alarmingproportion. The financial burden to society by this is markedly increasing every year.Materials and Methods: This randomized control study included 72 patients of age group 44–75 (36 studies and 36 controlgroups). The study group is provided sildenafil 25 mg daily orally for 36 days. The phase of the healing process is comparedin both groups.Results: In the study group, all 36 patients showed complete healing in 22 days but in control group, only 6 patients hadcomplete healing on 36 days and other 30 patients are at various stage of healing. The difference was obvious statistically.Conclusion: Although the sildenafil is mainly used for erectile dysfunction syndrome and other medical conditions its role inthe management of diabetic foot ulcer is commendable.

ABSTRACT
Introducción: Conocida la dificultad en el tratamiento de heridas crónicas de difícil curación, nos hemos propuesto evaluar las diferencias del progreso de la cicatrización tras intervención con métodos avanzados (Membranas Multifuncionales) y métodos tradicionales (apósitos de gasa húmedos a seco), durante un período de estudio de 12 semanas. Metodología: Un total de 380 pacientes que se presentaron a la Clínica de Curaciones de Consulta Externa del Departamento de Cirugía del Hospital Roosevelt, con heridas crónicas difíciles de curar, fueron distribuidos para su tratamiento en entorno ambulatorio a uno de dos grupos: a. con métodos avanzados (Membranas Multifuncionales) y b. con métodos tradicionales (apósitos de gasa húmedos a seco). La distribución en cada grupo se realizó mediante aleatorización simple según la secuencia de presentación: casos impares, para tratamientos avanzados con Membranas Multifuncionales y casos pares: con curas tradicionales (apósitos húmedos a secos). El principal resultado de interés fue determinar la eficacia en relación con la formación de tejido de granulación y/o tejido epitelial en el lecho de la herida con los dos métodos de tratamiento, utilizando para su valoración la escala modificada de Houghton y colaboradores (Photographic Wound Assessment Tool- PWAT por sus siglas en inglés-) Resultados: De enero a octubre de 2014, se seleccionaron 380 pacientes elegibles y se asignaron al azar a 190 pacientes en cada grupo. 129 pacientes (92 del grupo de apósito húmedo a seco y 37 de la Membrana Multifuncional), no concluyeron el ensayo por el incumplimiento/abandono del protocolo, permaneciendo en el estudio 251 pacientes para el seguimiento. El tiempo establecido para la recolección de datos fue en las semanas 4, 8 y 12. A las cuatro semanas, en la primera evaluación, el grupo tratado con la Membrana Multifuncional presentó cicatrización completa o cercana al cierre en el 50% de los casos, en comparación con el 28% de los apósitos húmedos a secos. A las ocho semanas, en la segunda evaluación, el grupo tratado con la Membrana Multifuncional presentó cicatrización completa o cercana al cierre en el 71% de los casos, en comparación con el 50% de apósitos húmedos a secos. En la evaluación final a las doce semanas, el grupo tratado con la Membrana Multifuncional presentó cicatrización completa o cercana al cierre en el 85% de los casos, en comparación con el 58% de los apósitos húmedos a secos. Conclusiones: En el presente estudio, en las heridas crónicas difíciles de curar, el grupo tratado con las membranas multifuncionales fue la alternativa que ofreció mayor éxito de cierre completo de la herida comparada con las lesiones tratadas con apósito húmedo a seco.
Introducton: Complicated chronic or difcult-to-heal wounds have led to propose the evaluaton between the diferences in progress of healing afer an interventon with advanced methods (Multfunctonal Membranes) and traditional methods (wet to dry gauze dressings), during a period of 12 weeks. Methods: From January to October 2014, 380 patents who presented at the Outpatient Wound Care Clinic of the Department of Surgery, Roosevelt Hospital, with chronic or difficult-to-heal wounds, were distributed for treatment in outpatient setting to one of two groups: a. with advanced methods (Multifunctional Membranes) and b. with traditional methods (wet-to-dry gauze dressings). The distribution in each group was made by simple randomization according to the presentation sequence: odd cases, for advanced treatments with Multifunctional Membranes and even cases: with traditional cures (wet to dry dressings). The main interest was to determine the efficacy in relation to the formation of granulation tissue and/or epithelial tissue in the wound bed with the two treatment methods, using for evaluation the modified scale of Houghton PWAT (Photographic Wound Assessment Tool). Results: 380 eligible patents were selected, and 190 patents were randomized in each group. 129 patents did not complete the trial due to noncompliance or dropout of the protocol, leaving 251 patents for follow-up. At four weeks, the group treated with the Multifunctional Membrane had completely healed or almost closed in 50% of cases, compared with 28% of wet to dry gauze dressings. At eight weeks, the group treated with the Multifunctional Membrane completely healed or almost closed in 71% of cases, compared with 50% of wet to dry gauze dressings. At twelve weeks, the group treated with the Multifunctional Membrane had completely healed or almost closed in 85% of cases, compared with 58% of wet to dry gauze dressings. Conclusions: The group treated with the multfunctonal membranes was the alternatve that ofered the greatest success of complete closure of the wound compared with the lesions treated with wet-to-dry dressing.

Introduction: Diabetic foot ulcer is one of the dreaded complications among the diabetic patients which are disabling, leading to repeated hospitalizations and even amputation, drastically reducing the quality of life. Hence proper management of diabetic foot infections by choosing appropriate antibiotic is crucial. The aim of the study: This study was undertaken to know about the prevalence of ESBL producing Enterobacteriaceae in Diabetic foot ulcers and their antibiotic sensitivity pattern to aid in the effective treatment of infection. Materials and methods: A total of 200 Pus samples were collected from the patients admitted and/ or attending in-patient or out-patient departments of Rajah Muthiah Medical College and Hospital. Only Enterobacteriaceae were isolated and antibiotic sensitivity testing was done according to CLSI guidelines. All the isolates were screened for ESBL and confirmed by phenotypic confirmatory tests. Results: A total of 60 Enterobacteriaceae were isolated from diabetic foot ulcer patients among which 27 (45%) isolates were ESBL producers. ESBL production is predominantly seen in E.coli (48.1%) followed by Klebsiella (44.4%), P. mirabilis (3.3%) and P. vulgaris (3.3%). ESBL producers were sensitive to Imipenam (88.9%), Amikacin (77.8%) and Gentamicin (55.6%) whereas highly resistant to Ampicillin, Amoxyclav, Cefuroxime and Ceftriaxone. Conclusion: This study shows the higher prevalence of ESBL producing Enterobacteriaceae in diabetic foot ulcers. Imipenam, Amikacin and Gentamicin can be used for empirical treatment but early identification and treatment according to antibiotic sensitivity pattern helps in preventing the emergence and propagation of multidrug resistance strains.

Objective To build new management model for diabetic foot disease,and to observe the therapeutic effect of diabetic foot ulcers under the new model.Methods 52 patients with newly diagnosed diabetic foot disease were recruited and randomly divided into the experimental group (n=26) and the control group (n=26).While the experimental group adopted the interdisciplinary collaboration model (nurse-doctor jointed diabetes care management model),the control group were treated by the single department pattern.The foot ulcer healing rate,average length of stay (ALOS),fasting plasma glucose (FPG),2 h postprandial blood glucose (2 h PBG),glycosylated hemoglobin (HbA1c),and the patient awareness of the knowledge about diabetes self-management were respectively compared at 3 and 6 months.Results After receiving a multidisciplinary joint diagnosis and treatment,FPG and 2 h PBG of the patients from the experimental group [(6.44±2.93)mmol/L,(8.52± 2.09)mmol/L] were significantly decreased than those of the patients from the control group [(8.17±3.19)mmol/L,(10.77±3.27)mmol/L].HbA1c at 3 and 6 months (7.2％,7.7％) and ulcer recurrence rate (3.8％) after 6 months of patients of the experimental group were significantly reduced than those of the control group(8.9％,9.1％ and 15.4％).When compared with patients of the control group,patients of varying severity in the experimental group showed significantly shortened ulcer healing time and hospital stay.Moreover,patients from the experimental group showed statistically higher knowledge level and self management ability (P＜0.05).Conclusion Through interdisciplinary collaboration,podiatric medical joint management model can significantly improve cure rate,shorten ALOS,improve blood sugar control and patient satisfaction.
ABSTRACT
[Summary] Neuroischemic diabetic foot ulcer ( NDFU) is characterized by infection, ulceration of deep tissues, neurological abnormalities, and various degrees of peripheral vascular disease in the lower limbs. The patients often have multiple risk factors such as older, longer duration, cardiovascular disease. The treatment is very difficult. The prognosis depends on the severity of complications, tissue range of infections, and the peripheral vascular disease. In this article, the treatment process of an old inpatient with NDFU and severe complications was reviewed and to propose a standard pathway for its management.
ABSTRACT
Background: a review of the literature found no clinical studies in which low level laser therapy (LLLT) and high voltage pulsed current (HVPC) were compared to evaluate their effectiveness in promoting wound healing. Objective: The purpose of this study was compare the effects of LLLT, HVPC and standard wound care (SWC) on the healing of diabetic foot ulcers. Methods: randomized controlled clinical trial where diabetic patients were divided in control group (CG) treated with SWC; HVPC group received HVPC plus SWC; LLLTgroup, treated with LLLT plus SWC. HVPC was applied 45min, 100pps and 100μs. LLLTparameters were 685nm, 30mW,2J/cm² applied to the wound edges and 1,5J/cm² in the wound bed. All subjects were treated 16 weeks or until the wound closed. The variables were healing, healing proportion, ulcers's characteristics, protective sensation, nerve conduction studies (NCS) and quality life. ANCOVA analysis and a Fisher's exact test were applied. Results: Twenty-eight subjects completed the protocol.The healing was reached by 7/9, 8/10 and 6/9 participants of the LLLT, HVPC and CG respectively in the 16th week. There were no statistically significant differences between the groups in the healing proportion, NCS, sensory testing or quality of life (p>0,05). Conclusions: The results of this study did not demonstrated additional effects of LLL or HVPC to the standard wound care (SWC) on healing of diabetic ulcers.
Introducción: La literatura revisada no registró estudios que compararan la efectividad del láser debaja potencia (LBP) y la corriente pulsada de alto voltaje (CPAV) sobre la cicatrización de úlceras diabéticas. Objetivo: Comparar los efectos del LBP, la CPAV y el cuidado de enfermería estándar (CEE) sobre la cicatrización de úlceras diabéticas. Métodos: Ensayo clínico controlado con asignación a: grupo control (GC) tratado con CEE; (CPAV) recibió CPAV más CEE y (LBP) tratado con LBP más CEE. La CPAV se aplicó por 45min, 100pps y 100μs. Los parámetros del LBP fueron 685NM, 30mW y 2J/cm² aplicado en los bordes de la herida y 1,5J/cm² en los bordes de la herida. Todas las personas fueron tratadas por 16 semanas o hasta el cierre de la herida. Las variables fueron cicatrización, proporción de cicatrización, características de las úlceras, sensación protectora, estudios de conducción nerviosa (ECN) y calidad de vida. Para el análisis se aplicaron un ANCOVA y el test exacto de Fisher. Resultados: El protocolo fue completado por 28 personas. La cicatrización se logró en 7/9, 8/10 y 6/9 participantes de LBP, CPAV y CEE respectivamente, hasta la semana 16. No hubo diferencias significativas entre los grupos en la proporción de cicatrización, ECN, evaluación sensorial o calidad de vida (p>0,05). Conclusión: Los resultados de este estudio no demostraron efectos adicionales del LBP o de la CPAV, al cuidado de enfermería estándar, sobre la cicatrización de úlceras de pie diabético.
