Effective treatments for non-healing burn wounds are an unmet need for 95% of burn sufferers. Approaches currently available to treat non-healing burn wounds are not satisfactory due to undesirable side-effects or expense. The anti-oxidation and antibacterial activities of walnuts are recommended for treating chronic diseases. Walnut ointment has been developed and successfully applied to treat non-healing burn wounds in our hospital for decades. We report herein a detailed retrospective case review examining patients’ response to the walnut ointment. The walnut ointment has shortened healing time of non-healing burn wounds and improved clinical outcomes. In order to investigate the mechanism of action, walnut ointment has been applied on wounds of porcine full-thickness burn wound models. Histological and immunohistochemical analysis indicated our walnut ointment supports wound healing through promoting keratinocyte proliferation and differentiation. Taken together, we recommend the walnut ointment offers an effective and economical treatment for patients presenting with non-healing burn wounds. 相似文献

BackgroundIncisional hernias (IH) following a laparotomy, on average, occur in 10–20% of patients, however, little is known about its molecular basis. Thus, a better understanding of the molecular mechanisms could lead to the identification of key target(s) to intervene pre-and post-operatively.MethodsWe examined the current literature describing the molecular mechanisms of IH and overlap these factors with smoking, abdominal aortic aneurysm, obesity, diabetes mellitus, and diverticulitis.ResultsThe expression levels of collagen I and III, matrix metalloproteinases, and tissue inhibitors of metalloproteases are abnormal in the extracellular matrix (ECM) of IH patients and ECM disorganization has an overlap with these comorbid conditions.ConclusionUnderstanding the pathophysiology of IH development and associated risk factors will allow physicians to identify patients that may be at increased risk for IH and to possibly act preemptively to decrease the incidence of IH. 相似文献

BackgroundBody contouring in the postbariatric surgery patient improves quality of life and daily function.ObjectivesTo determine the risk profile of panniculectomy when performed in select patients at the time of bariatric surgery.SettingMetabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) participating centers.MethodsWe examined the MBSAQIP database (2016-2017), in which data on 379,544 bariatric surgeries are reported. Concurrent panniculectomy procedures were identified by Current Procedural Technology (CPT) codes. Patient characteristics and in-hospital as well as 30-day complications were compared between the body contouring group and propensity score-matched bariatric surgery controls.ResultsOne hundred twenty-four patients met inclusion criteria and were matched to 248 controls. An infra-umbilical panniculectomy was performed in the majority of patients (n = 94, 75.8%). Most patients received an open rather than laparoscopic bariatric surgery (n = 87, 70.2%). There were no statistically significant differences between 30-day mortality (1.9%), wound complications (11.5%), readmission (12.5%) and reoperation (5.8%) between the 2 groups (P > .05). Wound complications occurred in 11.5% of patients and were associated with prolonged hospital stay (odds ratio 4.65, 95% confidence interval 1.99–10.86, P < .001) and a body mass index (BMI) > 50 (odds ratio 3.19, 95% confidence interval 1.02–9.96, P = .046).ConclusionIn select patients, panniculectomy at the time of bariatric surgery was not associated with increased in-hospital or 30-day adverse outcomes compared with matched bariatric surgery controls. This procedure may be performed in select patients, with awareness that revision surgery may be needed once weight loss stabilizes. 相似文献

目的分析负压封闭引流(vacuum sealing drainage,VSD)能否促进糖尿病足溃疡的愈合。方法回顾分析自2015年1月至2019年12月,北部战区总医院烧伤整形科收治的糖尿病足溃疡患者60例,并根据患者的治疗方式分为常规治疗组(30例)和VSD治疗组(30例)。统计对比分析两组患者的平均换药次数、平均愈合时间、疼痛程度及满意度。搜集治疗前和治疗14 d后的肉芽组织进行HE染色和VEGF免疫组化染色,分析创面愈合情况以及VEGF的表达情况。结果VSD治疗组换药次数[(5.40±0.28)次]显著少于常规治疗组[(31.41±1.11)次],组间比较P<0.05;VSD治疗组平均愈合时间(29.38±0.63)d显著短于常规治疗组(50.81±2.15)d,组间比较P<0.05;VSD治疗组患者的痛苦程度明显轻于常规治疗组,满意度显著优于常规治疗组,组间比较P<0.05。结论VSD治疗能够促进创面成纤维细胞的增殖、减少炎性细胞的浸润、促进VEGF的表达及创面的愈合。 相似文献

目的 比较膝关节屈曲90°连续缝合切口和膝关节伸直位连续缝合切口在全膝关节置换术(total knee arthroplasty,TKA)中的应用效果。方法 选择2017年1月至2019年1月我院收治的122例拟行TKA手术的病人,采用随机数字表法将病人分为两组,对照组(61例)采用膝关节伸直位连续缝合切口,观察组(61例)采用膝关节屈曲90°连续缝合切口。比较两组病人切口长度、缝合时间、手术时间、术后失血量、直腿抬高活动时间、屈膝90°活动时间、拆线时间、住院时间、Hollander切口愈合(Hollander wound evaluation scale,HWES)评分、美国纽约特种外科医院(American hospital for special surgery,HSS)膝关节评分、Rasmussen评分、膝关节活动范围(ROM)、疼痛视觉模拟量表(visual analogue scale,VAS)以及术后并发症差异。结果 两组切口长度、缝合时间、手术时间、术后失血量、直腿抬高活动时间、拆线时间、住院时间、HWES评分、并发症发生率比较,差异均无统计学意义(P均>0.05)。观察组屈膝90°活动时间短于对照组,术后24 h、48 h的HSS评分、Rasmussen评分高于对照组,膝关节ROM大于对照组,术后24 h、48 h、72 h的VAS评分均低于对照组,差异均有统计学意义(P均<0.05)。结论 膝关节屈曲90°连续缝合切口可减轻术后早期疼痛程度,利于膝关节功能恢复,且不增加并发症发生风险。 相似文献

This article explores the professional project for an emergent subaltern specialist community of wound healing clinicians. Drawing on the literature on professions and boundary work, it examines how wound healing clinicians challenge the perception of their work as ‘dirty’ and seek its transformation into a specialism of ‘woundology’. The article is based on an ethnography of a UK multidisciplinary team of doctors and nurses with an interest and expertise in wound healing, who work as clinical academics and provide wound care services in outpatient clinics. It demonstrates that wound healing clinicians vindicate their professional status by seeking to enthral the medical community in ‘dirty wound care’ as a focused clinical specialty of ‘woundology’. Through training nurses to do medical wound care work, educating clinicians from other specialties about wounds and undertaking wound research, wound healing clinicians assert the professional boundaries of their specialism and its fit with mainstream medicine without embellishing the dirty aspects of their work. 相似文献
