    背景:Dupuytren的挛缩症是一种遗传性疾病,可导致手部手掌膜进行性纤维化,导致受影响射线的数字屈曲挛缩。有限的筋膜切除术是Dupuytren的标准手术治疗方法,和复发率最低的;然而,复发率仍然相对较高(2-39%)。脂肪来源的干细胞已被证明在体外抑制Dupuytren的肌成纤维细胞的增殖和收缩,以及在不同类型的手术中改善疤痕质量和皮肤再生。自体脂肪组织移植已被研究作为经皮穿刺筋膜切开术的辅助治疗方法,效果良好。但直到最近才与有限的筋膜切除术有关。REMEDY试验的目的是研究与仅进行有限的筋膜切除术相比,自体脂肪组织移植的有限的筋膜切除术是否会减少复发。
    方法:REMEDY试验是一项多中心开放标签随机对照试验(RCT),分配比例为1:1。参与者(n=150)将被随机分为两组,自体脂肪组织移植的有限筋膜切除术与单独的有限筋膜切除术。主要结果是术后2年任何治疗后的Dupuytren挛缩复发。次要结果是3年和5年复发,疤痕质量,并发症,醛营养不良(复杂的区域疼痛综合征)的发生,患者报告的手功能,以及一小部分患者术后1年的皮下脂肪组织丢失。
    结论:REMEDY试验是研究与自体脂肪组织移植相关的有限筋膜切除术治疗Dupuytren挛缩症的首批研究之一,and,根据我们的知识,第一个研究这种治疗的长期结果。它将深入了解脂肪组织移植与有限的筋膜切除术相结合的可能好处,如降低复发率和改善瘢痕质量。
    背景:ClinicalTrials.govNCT05067764,2022年6月13日。
    BACKGROUND: Dupuytren\'s contracture is a hereditary disorder which causes progressive fibrosis of the palmar aponeurosis of the hand, resulting in digital flexion contractures of the affected rays. Limited fasciectomy is a standard surgical treatment for Dupuytren\'s, and the one with the lowest recurrence rate; however, the recurrence is still relatively high (2-39%). Adipose-derived stem cells have been shown to inhibit Dupuytren\'s myofibroblasts proliferation and contractility in vitro, as well as to improve scar quality and skin regeneration in different types of surgeries. Autologous adipose tissue grafting has already been investigated as an adjuvant treatment to percutaneous needle fasciotomy for Dupuytren\'s contracture with good results, but it was only recently associated with limited fasciectomy. The purpose of REMEDY trial is to investigate if limited fasciectomy with autologous adipose tissue grafting would decrease recurrence compared to limited fasciectomy alone.
    METHODS: The REMEDY trial is a multi-centre open-label randomised controlled trial (RCT) with 1:1 allocation ratio. Participants (n = 150) will be randomised into two groups, limited fasciectomy with autologous adipose tissue grafting versus limited fasciectomy alone. The primary outcome is the recurrence of Dupuytren\'s contracture on any of the treated rays at 2 years postoperatively. The secondary outcomes are recurrence at 3 and 5 years, scar quality, complications, occurrence of algodystrophy (complex regional pain syndrome), patient-reported hand function, and hypodermal adipose tissue loss at 1 year postoperatively in a small subset of patients.
    CONCLUSIONS: The REMEDY trial is one of the first studies investigating limited fasciectomy associated with autologous adipose tissue grafting for Dupuytren\'s contracture, and, to our knowledge, the first one investigating long-term outcomes of this treatment. It will provide insight into possible benefits of combining adipose tissue grafting with limited fasciectomy, such as lower recurrence rate and improvement of scar quality.
    BACKGROUND: ClinicalTrials.gov NCT05067764, June 13, 2022.

    BACKGROUND: Fat grafting is commonly utilized in breast surgery, and since it was first described, clinicians and researchers have stridden towards improvement of graft retention. Current advancements include adding adipose-derived mesenchymal stem/stromal cells (MSC(AT)s), which have demonstrated promise for improved graft retention.
    OBJECTIVE: This study reports outcomes for the first twenty-two patients undergoing breast augmentation (Stemform BA) or artificial implant replacement (Stemform AIR) with MSC(AT)-enriched fat in a real-world setting.
    METHODS: Autologous MSC(AT)s were isolated and expanded ex vivo, then mixed with lipoaspirate and injected as enriched fat for Stemform BA and AIR. The breast volume was measured preoperatively and at 3 and 12 months postoperative using a 3D Infinity Dual-Lens Camera and LifeVizApp software. Additionally, independent plastic surgeons evaluated clinical images, and patient satisfaction was obtained at equal time points.
    RESULTS: Twenty-two patients were included. All completed 3 and 12 months clinical follow-up and 3 months volume measurements. Nineteen patients completed 12 months volume measurements. The median fat graft retention at 12 months was 95.7% (IQR = 82.44-103.12%) for Stemform BA patients and 113.0% (IQR = 94.8-131.2%) for Stemform AIR patients. The Stemform BA patients had a median breast enlargement of 172.0% (IQR = 156.7-241.0%). The implant replacement volume of Stemform AIR patients was 102% (IQR = 85.1-130.3%). The patient reported 92.8% and 100% would elect to repeat treatment if they had the opportunity for Stemform BA and Stemform AIR, respectively.
    CONCLUSIONS: Breast augmentation and breast implant replacement patients receiving ex vivo-expanded MSC(AT)-enriched fat grafts had high graft retention and patient satisfaction scores. The paper confirms the clinical efficacy of using ex vivo-expanded MSC(AT)s. Level of Evidence V This journal requires that authors assign a level of evidence to each article.

    Introduction  Any injury involving the dermis will lead to scarring. Scar tissue can cause functional limitations, cosmetic impairments, pain, and itch. Adipose-derived stem cells have also been shown to play a role in scar modulation. This study evaluates changes in lipofilled scar over the period of time and compares it with non-lipofilled scar tissue. Materials and Methods  A prospective case-control study with intraindividual follow-up was performed on 30 adult patients with post-burn scars from November 2016 to May 2019. Clinical, histopathological, and immunohistochemical parameters were assessed among the case and control regions of the scar. Results  Mean age of the study population was 30.6 years. The duration of the scar included in this study ranged from 1 to 28 years, with a mean duration of 5.91 years. There was a significant reduction in pain, itch, stiffness, and an increase in the pliability of the scar, and a substantial improvement in the modified Vancouver Scar Score in the lipofilled group. In histopathological analysis, the case group showed organized parallel collagen fibers, a significant reduction in melanocytes, improvement in vascularity, and a significantly increased amount of collagen fibers at the reticular dermis. Immunohistochemical analysis indicated new cell synthesis in the scar tissue and reduced melanocytes. Conclusion  The remodeling effect of adipocyte-derived stem cells is long-lasting, and there is a gradual improvement in most of the parameters. Lipofilling has regenerative capacity, which leads to the improved overall appearance of scar and improvement at the cellular level.

    慢性伤口仍然是医生和医疗保健系统的治疗和财务挑战。创新,廉价而有效的治疗方法将具有巨大的价值。皮下脂肪移植可能是这样的治疗方法,尽管有效性和安全性仅在少数随机临床试验中进行了评估。脂肪移植物是通过吸脂术获得的,用Coleman方法清洗,然后在手术清创术后将皮损下注射到伤口边缘。对于对照组,使用盐水溶液代替脂肪。主要终点是确定两组的伤口大小减少。术前测量伤口,术中以及干预后3、7、21和60天。<0.05的p值被认为是显著的。此外,对伤口和疼痛的组织学和微生物学进行了评估。在14和21天后观察到治疗的暂时效果。干预组的伤口大小减少明显较大,而60天后,两组间无显著差异.未报告不良事件,对照组和干预组的疼痛程度几乎相等。皮损脂肪移植暂时增强了慢性伤口的愈合。手术安全,疼痛程度低。反复干预可能导致伤口完全闭合,这应该在未来的研究中确定。
    Chronic wounds remain a therapeutic and financial challenge for physicians and the health care systems. Innovative, inexpensive and effective treatment methods would be of immense value. The sublesional fat grafting could be such treatment, although effectiveness and safety have only been assessed in a few randomised clinical trials. The fat graft was obtained by liposuction, washed with the Coleman method and then injected sublesional and into the wound margins after surgical debridement. For the control group, saline solution was used instead of fat. The primary endpoint was to determine the wound size reduction in both groups. The wounds were measured preoperatively, intraoperatively and 3, 7, 21 and 60 days after the intervention. A p-value of <0.05 was considered significant. Furthermore, histology and microbiology of the wounds and pain were assessed. A temporary effect of the treatment was observed after 14 and 21 days. The wound size reduction was significantly larger in the intervention group, whereas after 60 days, no significant difference was detected between both groups. No adverse events could be reported and the pain level was almost equal in the control and intervention group. Sublesional fat grafting temporarily enhanced healing of chronic wounds. The procedure was safe and the pain level was low. Repeated interventions could lead to complete wound closure, which should be determined in future studies.

    脂肪增加的背阔肌皮瓣可以通过立即将脂肪移植到皮瓣中来克服背阔肌皮瓣的体积不足。当乳房皮肤补充是不必要的,背阔肌皮瓣可以作为肌肉皮瓣收获,以避免额外的背部切口。这里,我们比较了脂肪增强背阔肌肌皮瓣和肌肉皮瓣在全乳房重建中的疗效。我们回顾性分析了2017年9月至2022年3月在我院使用脂肪增强背阔肌皮瓣(肌肉:40,肌皮:54)进行单侧全乳房重建的94例。肌瓣组手术时间明显短于肌皮瓣组(p<0.0001)。两组之间乳房切除术标本重量没有差异,但肌瓣组皮瓣总重显著降低(p<0.0001)。相反,总脂肪移植体积,脂肪移植到背阔肌皮瓣的体积,肌瓣组的胸大肌和脂肪移植物体积明显更大(分别为p<0.0001,p<0.0001和p=0.02)。肌瓣组需要额外脂肪移植的病例百分比明显较高,但两组术后美学评价无显著差异.两组在每个BREAST-Q项目上得分都很高,但是肌瓣组的“背部满意度”得分明显更高。“尽管额外的脂肪移植的频率高于脂肪增加的背阔肌肌皮瓣,用脂肪增强背阔肌皮瓣进行全乳房再造是一种可行的技术,手术时间短,患者满意度高。
    The fat-augmented latissimus dorsi myocutaneous flap can overcome the volume insufficiency of latissimus dorsi flaps by immediate fat grafting into the flap. When breast skin supplementation is unnecessary, latissimus dorsi flaps can be harvested as a muscle flap to avoid an additional back incision. Here, we compared the efficacy of fat-augmented latissimus dorsi myocutaneous and muscle flaps in total breast reconstruction. We retrospectively reviewed 94 cases of unilateral total breast reconstruction using fat-augmented latissimus dorsi flaps (muscle: 40, myocutaneous: 54) at our hospital from September 2017 to March 2022. The muscle flap group had a significantly shorter operative time than the myocutaneous flap group (p < 0.0001). Mastectomy specimen weight did not differ between the 2 groups, but total flap weight in the muscle flap group was significantly lower (p < 0.0001). Conversely, total fat graft volume, fat graft volume to the latissimus dorsi flap, and fat graft volume to the pectoralis major muscle were significantly greater in the muscle flap group (p < 0.0001, p < 0.0001, and p = 0.02, respectively). The percentage of cases requiring additional fat grafting was significantly higher in the muscle flap group, but postoperative esthetic evaluation did not significantly differ between the 2 groups. Both groups scored high on each BREAST-Q item, but the muscle flap group scored significantly higher for \"Satisfaction with Back.\" Although the frequency of additional fat grafting was higher than with fat-augmented latissimus dorsi myocutaneous flaps, total breast reconstruction with fat-augmented latissimus dorsi muscle flaps is a viable technique with a short operative time and high patient satisfaction.

    眼球内陷的一种新的治疗方法可能是球后脂肪填充。本研究旨在标准化腔内填充技术,并通过计算机断层扫描(CT)评估眼球移位的程度。在两次5%碘化的腔内注射之前和之后,对六只狗的尸体进行了颅骨CT,粘弹性溶液,一只眼睛,使用超声引导颞上入路。使用球后锥体麻醉的公式计算要注射的体积。CT后,对犬进行了尸检和组织病理学检查,以评估最终发生在球后结构上的损伤.使用两种基于CT的方法估计眼球位移,名为M1和M2。Wilcoxon符号秩检验显示两种注射材料在两种M1中没有显着差异(p>0.99),和M2(横向p=0.84,头端p=0.84位移)。注射前和注射后M1组之间存在统计学上的显着差异(p=0.002),M2(p=0.004)为侧向位移(p=0.003)。虽然轻微的眼球位移,球后填充可导致眼球内陷的分辨率。与M1相比,M2方法具有更好定义的解剖标志。Further,临床前体内研究对于评估球后填充的有效性和安全性是必要的。
    A new therapeutic approach for enophthalmos may be retrobulbar lipofilling. This study aims to standardize the intraconal filling technique and to evaluate the degree of eyeball displacement by computed tomography (CT). Skull CT was performed on six dog cadavers before and after intraconal injection of two 5% iodinated, viscoelastic solutions, one per eye, using an ultrasound-guided supratemporal approach. The volume to be injected was calculated using formulas for retrobulbar cone anesthesia. After CT, the dogs underwent necropsy and histopathology to evaluate damages that eventually occurred to retrobulbar structures. Eyeball displacement was estimated using two CT-based methods, named M1 and M2. The Wilcoxon signed-rank test revealed no significant difference between the two injected materials in both M1 (p > 0.99), and M2 (lateral p = 0.84 and rostral p = 0.84 displacement). A statistically significant difference was found between the pre- and post-injection group M1 (p = 0.002), M2 (p = 0.004) for the lateral and (p = 0.003) for rostral displacement. Although the slight eyeball displacement, the retrobulbar filling can lead to enophthalmos resolution. Compared to M1, the M2 method has better-defined anatomical landmarks. Further, preclinical in vivo studies are necessary to assess retrobulbar filling efficacy and safety.

    充脂是乳房重建的常用且安全的程序。最令人恐惧的并发症之一是脂肪填充后的软组织感染。正因为如此,一些外科医生提出用抗生素冲洗脂肪移植物的做法。这项研究调查了在体外模型中抗生素冲洗对脂肪移植物的影响。从24次脂肪填充过程中收获的脂肪组织中分离脂肪细胞和干细胞,并与不同剂量的克林霉素或头孢唑啉一起孵育。细胞活力,新陈代谢,扩散,分化能力通过总体形态分析,荧光染色,-(4,5-二甲基噻唑-2-基)-2,5-二苯基四唑三溴胺(MTT-),和甘油醛3磷酸脱氢酶(G3PD)测定以及活性氧(ROS)测定。头孢唑啉和克林霉素导致脂肪细胞的细胞活力显着降低。高剂量的两种抗生素均导致脂肪细胞破裂,并带有可见的游离脂滴。与两种抗生素孵育后,细胞代谢显着降低。ROS产量显著增加。暴露于克林霉素和头孢唑啉以剂量和时间依赖性方式导致干细胞的形态变化。此外,分化潜能显著降低。抗生素药敏试验,然而,结果表明,低浓度的抗生素可以有效抑制受污染的脂肪移植物中的细菌生长。这项研究证实,用克林霉素或头孢唑啉冲洗脂肪移植物不仅过度预防感染,而且对脂肪细胞具有细胞毒性和代谢作用。因此,基于这些结果,不推荐高剂量的常规临床应用。
    Lipofilling is a frequently used and safe procedure for breast reconstruction. One of the most feared complications is soft tissue infection following lipofilling. Because of this, some surgeons propose the practice of rinsing fat grafts with antibiotics. This study investigates the effect of antibiotic rinses on fat grafts in an in vitro model. Adipocytes and stem cells were isolated from fat tissue harvested during 24 lipofilling procedures and incubated with different doses of clindamycin or cefazolin. Cell viability, metabolism, proliferation, and differentiation capacities were analyzed by gross morphology, fluorescence staining, -(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromid (MTT-), and Glyceraldehyde 3 Phosphate Dehydrogenase (G3PD)-assay as well as reactive oxygen species (ROS)-assay. Cefazolin and clindamycin led to significant reduction of cell viability of adipocytes. High doses of both antibiotics led to a rupture of adipocytes with visible free lipid droplets. Cell metabolism was significantly decreased after incubation with both antibiotics. There was a significant increase in ROS production. Exposure to clindamycin and cefazolin led to morphological changes in stem cells in a dose- and time-dependent manner. Furthermore, differentiation potential was significantly reduced. Antibiotic susceptibility testing, however, showed that low concentrations of antibiotics effectively inhibited bacterial growth in contaminated fat grafts. This study confirms that rinsing fat grafts with clindamycin or cefazolin not only overly prevents infection but also has cytotoxic and metabolic effects on adipocytes. Therefore, based on these results, the routine clinical application in high doses cannot be recommended.

    背景:外阴硬化性苔藓(VLS)的一线治疗是3个月的局部皮质类固醇治疗。然而,对于一线治疗无反应的患者,使用脂肪移植和富血小板血浆作为二线治疗的证据有限.
    方法:这项前瞻性单中心随机先导试验包括20例临床和组织学诊断为中度至重度VLS的患者。治疗组(TG)的患者接受了两次浸润(间隔3个月)的纳米脂肪和富血小板血浆(PRP)混合到外阴区,而对照组(CG)接受标准的局部皮质类固醇治疗。从大腿内侧或下腹部抽吸脂肪。离心后获得微脂肪并乳化以获得纳米脂肪悬浮液。通过测量外阴皮肤弹性的变化来确定治疗效果,组织病理学,和临床症状,症状,和患者1年后的生活质量。
    结果:最终评估了19例患者(9TG和10CG)。在研究结束时(1年),外阴皮肤弹性没有明显改善。然而,TG患者的症状显着改善(瘙痒,疼痛,燃烧,和性交困难)和临床体征(宫颈糜烂,裂缝,狭窄,和白斑病)。皮肤活检分析显示,TG中所有炎症细胞类型均显着减少。没有记录到与自体治疗相关的不良事件。
    结论:与外用皮质类固醇相比,间隔3个月进行的两次浸润减少了外阴的炎症,并改善了与VLS相关的大多数临床体征和症状。尽管如此,自体治疗没有改善外阴皮肤弹性。

    The first-line treatment for vulvar lichen sclerosus (VLS) is 3 months of topical corticosteroid therapy. However, limited evidence is available concerning the use of fat grafting and platelet-rich plasma as a second-line treatment for patients who do not respond to first-line treatment.
    This prospective single-center randomized pilot trial included 20 patients with a clinical and histological diagnosis of moderate to severe VLS. The patients in the treatment group (TG) received two infiltrations (at 3-month intervals) of nanofat mixed with platelet-rich plasma (PRP) into the vulvar area, while the control group (CG) received standard topical corticosteroid therapy. Fat was aspirated from the medial thigh or lower abdomen regions. Microfat was obtained after centrifugation and was emulsified to obtain a nanofat suspension. Treatment efficacy was determined by measuring changes in the vulvar skin elasticity, histopathology, and clinical signs, symptoms, and patient quality of life at after 1 year.
    A total of 19 patients were finally assessed (9 TG and 10 CG). At the end of the study (1 year), there had been no significant improvement in vulvar skin elasticity. However, patients in the TG showed a significant improvement in their symptoms (itching, pain, burning, and dyspareunia) and clinical signs (cervical erosions, fissures, stenosis, and leukoderma). Analysis of skin biopsies revealed a significant decrease in all inflammatory cell types in the TG. No adverse events related to the autologous treatment were recorded.
    Compared with topical corticosteroids, two infiltrations delivered 3 months apart decreased the inflammation of the vulva and improved most of the clinical signs and symptoms associated with VLS. Nonetheless, no improvement in vulvar skin elasticity was derived from the autologous treatment.

    BACKGROUND: Autologous fat grafting (AFG), defined as the re-implant to the breast of fat tissue from different body areas, has been firstly applied to esthetic plastic surgery and then has moved to reconstructive surgery, mainly used for scar correction and opposite breast altering. Nevertheless, due to the potentially unsafe stem-like properties of adipocytes at the tumoral bed level, no clear evidence of the procedure\'s oncological safety has been clearly documented at present.
    METHODS: We retrospectively collected data of early breast cancer (BC) patients from 17 Italian Breast Units and assessed differences in terms of locoregional recurrence rate (LRR) and locoregional recurrence-free survival (LRFS) between patients who underwent AFG and patients who did not. Differences were analyzed in the entire cohort of invasive tumors and in different subgroups, according to prognostic biological subtypes.
    RESULTS: With a median follow-up time of 60 months, LRR was 5.3% (n = 71) in the matched population, 3.9% (n = 18) in the AFG group, and 6.1% (n = 53) in the non-AFG group, suggesting non-inferiority of AFG (p = 0.084). Building Kaplan-Meier curves confirmed non-inferiority of the AFG procedure for LRFS (aHR 0.73, 95% CI 0.41-1.30, p = 0.291). The same effect, in terms of LRFS, was also documented among different biological subtypes (luminal-like group, aHR 0.76, 95% CI 0.34-1.68, p = 0.493; HER2 enriched-like, aHR 0.89, 95% CI 0.19-4.22, p = 0.882; and TNBC, aHR 0.61, 95% CI 0.12-2.98, p = 0.543).
    CONCLUSIONS: Our study confirms in a very large, multicenter cohort of early BC patients that, aside the well-known benefits on the esthetic result, AFG do not interfere negatively with cancer prognosis.
