ABSTRACT
Epidermolysis bullosa (EB) is a group of rare genetic skin disorders characterised by skin fragility and chronic, painful wounds that are highly susceptible to bacterial infection, particularly by Staphylococcus aureus (SA). This study evaluated the efficacy of an acid-oxidising solution containing hypochlorous acid (HOCl) in reducing SA colonisation, promoting wound healing, and restoring a healthier microbiome in EB wounds. In a 12-week open-label pilot study, 15EB patients applied the HOCl-based spray (APR-TD011) daily to chronic wounds for 8weeks, with full-length 16S rRNA sequencing of wound swabs performed before, during, and after treatment. At baseline, 87% of patients were culture-positive for SA, and sequencing revealed that SA had the highest relative abundance (34%), followed by Acinetobacter guillouiae and Pseudomonas poae. SA relative abundance decreased precipitously by Weeks 4 (to 11%) and 8 (primary endpoint; to 10%, p<0.01), and this effect persisted at 4weeks post-treatment (Week 12; to 9.7%), including for methicillin-resistant SA. Concurrently, bacterial diversity increased, and wound sizes diminished in correlation with reduced SA levels (r=0.64). Younger patients exhibited greater SA reduction trends. The treatment was well-tolerated, with minimal adverse effects and high patient satisfaction. This study underscores the role of microbial dysbiosis in EB wounds and highlights HOCl-based solutions as a promising therapy to mitigate pathogenic burden and enhance wound healing.

男性,24岁,3年前外院诊断“下丘脑生殖细胞瘤”,进行γ刀治疗后,长期应用“氢化可的松”早晚各2片维持,半年前不慎损伤左小腿下部外侧皮肤,之后长期不愈合,收入院。
含银的敷料是目前治疗糖尿病足的主流敷料,有各种剂型,包括泡沫状、胶冻态、液态、粉末态、膏态等等,生产的厂家的非常多,其中的质量良莠不齐,很难鉴别。
进一步的清创就到了骨骼,对于骨髓炎最彻底的治疗方法就是去除被细菌侵袭的骨,正常的骨骼一般是浅黄色,如果发白或者变黑,往往就提示这段骨头可能活性比较差,另外,还有一种是面积比较大的骨暴露,一般的肉芽组织很难爬上去,因此,对于坏死的骨头及较大面积的骨暴露,一般需要清除。
皮下组织中的脂肪组织在足部分布广泛,而皮下脂肪中血管分布非常少,在相对或绝对缺血的糖尿病足中,脂肪组织边缘的是否出血不是其是否存活的可靠指标。
这是一个我们在《糖尿病足切开设计(1)》中提到过,这次从不同角度谈谈足趾的保全。
大趾是足部最重要的结构,如果被切除,对足部的功能会有比较大的影响,因此,应该尽可能的保存。
