前列地尔辅助硫辛酸治疗糖尿病足溃疡合并感染的临床效果

目的探讨前列地尔辅助硫辛酸治疗糖尿病足溃疡合并感染对患者胰岛素样生长因子-1(IGF-1)、纤维连接蛋白(FN)、血管内皮生长因子(VEGF)水平及足背血流动力学的影响。方法选取2017年5月-2019年5月新疆医科大学第一附属医院收治的104例糖尿病足溃疡合并感染患者,采用随机数字表法将所选患者分为研究组(n=52)和对照组(n=52)。对照组给予硫辛酸进行治疗,研究组在此基础上给予前列地尔进行治疗,两组均治疗4周。比较两组治疗4周后的下肢静息疼痛改善情况,治疗前、治疗4周后的血清IGF-1、FN、VEGF水平及足背动脉血流速度和足背动脉内径,统计两组治疗期间的不良反应发生率。结果治疗4周后,研究组下肢静息疼痛总改善率为96.15%,高于对照组(P<0.05)。与治疗前比,治疗4周后,两组血清IGF-1、FN、VEGF水平及足背动脉血流速度、足背动脉内径均升高,且研究组均高于对照组(P<0.05)。治疗期间,研究组不良反应发生率为5.77%,低于对照组(P<0.05)。结论前列地尔辅助硫辛酸治疗糖尿病足溃疡合并感染,可显著提高患者血清IGF-1、FN、VEGF水平,改善其足背血流动力学,并能缓解患者下肢静息疼痛,降低不良反应发生率。

Bioactive glass,a new tool for the treatment in the diabetic foot recalcitrant osteomyelitis: A case series with 24-month follow-up

BackgroundThe bioactive glass (BAG) is a promising solution for the reconstruction of bone defects and the eradication of infection in patients with osteomyelitis, however references to the treatment of diabetic foot osteomyelitis are scarce in the literature.MethodsOur experience in patients with diabetic foot osteomyelitis, who required surgical debridement and void filling, in which we use bioactive glass (n = 6), was evaluated. During a minimum follow-up of 24 months, the presence of persistent infection and healing rate, post-surgical complications, surgical reinterventions, degree of osseointegration and BAG-related side effects was analyzed.ResultsAt the end of the follow-up, none of the patients showed signs of persistent infection and the healing rate was 66.6% (4/6).Postoperative complications were noted in 3 patients and two of the them required new surgical intervention, both due to skin coverage or vascular complications.A complete osseointegration in the 66.6% of the patients and no cases of local adverse effects were recorded.ConclusionsThe bioactive glass can be a useful tool in the treatment of certain cases of diabetic foot osteomyelitis, provided that a multidisciplinary approach and strict patient selection is in place.Level of evidenceIV.     

Conservative surgery for chronic diabetic foot osteomyelitis: Procedures and recommendations

Osteomyelitis (OM) is the most frequent infection associated with diabetic foot ulcers (DFU) that typically involve the forefoot, the most common location of DFU.Conservative surgical procedures could be attractive alternative that reduces minor and major amputations and avoid future recurrence thus preserving the functionally of the foot. This review aimed to analyze and describe the current evidence on conservative diabetic foot osteomyelitis (DFO) surgical procedures depending on DFU location and indications.A narrative revision of the evidence was carried out by searching Medline through PubMed databases from inception to late July 2020 to identify retrospective, prospective, and randomized controlled trials pertaining to conservative DFO procedures on the forefoot.Seven types of conservative surgical procedures for DFO treatment in the forefoot are described in this review: (1) partial or total distal phalangectomy, (2) arthroplasty of the proximal or distal interphalangeal joint, (3) distal Syme amputation, (4) percutaneous flexor tenotomy, (5) sesamoidectomy, (6) arthroplasty of the metatarsophalangeal joint, and (7) metatarsal head resection.When indicated, conservative surgery for DFUs in patients with chronic forefoot OM is a safe and effective option that increases the chances of healing and reduces the possibility of limb loss and death compared with radical amputation procedures.Since a lack of sufficient evidence supporting this procedure exists, future investigations should be focused on the random clinical trial (RCT) design. The results of prospective trials could help surgeons select the appropriate procedure in each case in order to minimize complications.     

足部穴位按摩护理0级糖尿病足患者有效性的系统评价

目的:对足部穴位按摩护理0级糖尿病足的相关文献进行系统评价,证实其应用效果,为临床实践提供参考。方法:计算机检索Cochrane Library、PubMed、Embase、Web of Science、Ebsco、中国知网(CNKI)、万方数据知识服务平台(WanFang Data)、维普期刊资源整合服务平台(VIP)和中国生物医学文献数据库(CBM)中有关足部按摩治疗0级糖尿病足的随机对照试验(RCT)和半随机对照试验(CCT),检索时间均从建库至2020年3月。由2名研究员进行文献筛选、资料提取及质量评价后,利用RevMan 5.3软件进行Meta分析。结果:筛选、资料提取及质量评价后,利用RevMan 5.3软件进行Meta分析。最终纳入10篇原始文献,包括11项研究,共计663例患者,根据不同干预措施分为4个亚组。文献质量评价结果均为B级。Meta分析结果显示:实施足部穴位按摩可提高患者护理有效率[RR=1.43, 95%CI(1.25, 1.63),P0.00001];提高患者踝肱比[MD=0.22,95%CI(0.15,0.30),P0.00001]。结论:对0级糖尿病足患者实施足部穴位按摩优于常规护理,但需继续开展多中心、大样本、高质量随机对照试验进一步证实,并分析联合不同中医护理技术的疗效差异。     

Wound outcomes and factors associated with wound healing after first-time femoropopliteal artery intervention in patients with ischemic tissue loss

Background/objectiveThis study’s goal is to describe wound outcomes at 2 years following intervention for atherosclerotic femoropopliteal lesions in patients with ischemic tissue loss.MethodsA retrospective review of 135 first-time endovascular procedures for chronic femoropopliteal atherosclerotic lesions related to ischemic tissue loss was performed. The final wound outcomes were categorized according to the initial wound healing, recurrence and the need of major/minor amputation.ResultsAt 2-years of follow up, 76 limbs (56.3%) showed complete wound healing without recurrence, however, wound development occurred at other sites on the same foot following complete primary healing in 11 limbs (8.1%). Tolerable wounds persisted or wounds recurred at the same site in 30 limbs (22.2%), and 18 limbs (13.3%) needed major amputations. Independent factors that prevented wound healing without recurrence at 2 years were renal insufficiency (HR = 0.225, 95% C.I. = 0.091–0.556, p = 0.001), ankle pressure < 50 mmHg or flat forefoot PVR (HR = 0.328, 95% C.I. = 0.124–0.867, p = 0.025) and functional performance < 4 metabolic equivalents (MET) (HR = 0.150, 95% C.I. = 0.063–0.360, p < 0.001).ConclusionWound outcome classifications showed detailed information regarding clinical outcomes in patients with ischemic tissue loss. Renal insufficiency, ischemia grade 3 and poor functional performance were independent risk factors that prevented wound healing.
