Background

Hyaluronic acid (HA) fillers are commonly used in esthetic medicine for facial contouring and rejuvenation. However, complications such as overcorrection, vascular occlusion, and irregular filler distribution necessitate the use of hyaluronidase to dissolve the fillers. This study aimed to evaluate the efficacy of hyaluronidase in degrading different types of HA fillers and provide clinical guidelines for its use based on filler type, dosage, and application techniques.

Methods

A series of in vitro and in vivo experiments were conducted to assess the dissolution of biphasic and monophasic HA fillers using varying concentrations of hyaluronidase. The in vivo component used animal models to determine the duration of hyaluronidase activity in biological tissues, whereas the in vitro study examined the dissolution rates of HA fillers in response to different hyaluronidase concentrations and application methods. A control study using saline was also performed to compare the natural hydration process of the fillers.

Results

Hyaluronidase efficacy was found to vary based on the type of HA filler and the enzyme's concentration. Biphasic fillers dissolved more rapidly at lower concentrations of hyaluronidase compared to monophasic fillers, which required higher concentrations and longer exposure times for effective breakdown. The study also demonstrated that direct injection of hyaluronidase into the filler mass was more effective than surface application. Pharmacokinetic analysis revealed that hyaluronidase activity diminished within 30 min in biological tissues, highlighting the need for timely intervention in clinical scenarios.

Conclusion

Hyaluronidase is effective in dissolving HA fillers, with its efficacy dependent on the type of filler, concentration, and application technique. Biphasic fillers respond more quickly to hyaluronidase, whereas monophasic fillers require higher doses and multiple treatments. Clinical recommendations include using direct injection techniques, tailoring hyaluronidase dosage based on the filler type, and considering hypersensitivity reactions. Future research should focus on the long-term effects of hyaluronidase and refining clinical protocols for its use.

背景:透明质酸(HA)填充剂通常用于美容医学,用于面部轮廓和年轻化。然而,由于矫治过度、血管闭塞和填充物分布不规则等并发症,需要使用透明质酸酶溶解填充物。本研究旨在评价透明质酸酶降解不同类型透明质酸填充物的效果,并根据填充物类型、用量和应用技术为其临床使用提供指导。方法:采用一系列体外和体内实验,评估不同浓度透明质酸酶对双相和单相透明质酸填料的溶解作用。体内部分使用动物模型来确定生物组织中透明质酸酶活性的持续时间,而体外研究则检测了透明质酸填充物对不同透明质酸酶浓度和应用方法的溶出率。用生理盐水进行对照研究,比较填料的自然水化过程。结果:透明质酸酶的功效因透明质酸填料的类型和酶的浓度而异。与需要更高浓度和更长的暴露时间才能有效分解的单相填料相比,双相填料在较低浓度的透明质酸酶下溶解得更快。研究还表明,透明质酸酶直接注射到填充物中比表面注射更有效。药代动力学分析显示,生物组织中透明质酸酶活性在30分钟内下降,强调了在临床情况下及时干预的必要性。结论:透明质酸酶能有效溶解透明质酸填充物,其溶解效果与填充物的种类、浓度和应用技术有关。双相填充物对透明质酸酶反应更快,而单相填充物需要更高的剂量和多次处理。临床建议包括使用直接注射技术,根据填充物类型调整透明质酸酶的剂量,并考虑过敏反应。未来的研究应集中在透明质酸酶的长期影响和完善其使用的临床方案。

Background

Benzoyl peroxide (BPO) is widely used in dermatological aesthetics for treating acne and other skin conditions. However, its potential adverse reactions remain a concern.

Aims

This study aimed to investigate the application of BPO in dermatological aesthetics, analyze its associated adverse reactions, and provide insights into patient safety.

Methods

The study analyzed adverse reaction reports related to BPO in the Food and Drug Administration's Adverse Event Reporting System database from 2004 to 2024. Demographic characteristics, types of adverse reactions, and specific issues related to the novel drug EPSOLAY (5% microencapsulated BPO) were examined.

Results

The findings reveal that BPO users are predominantly female (74.18%), with a significant proportion falling within the 18–44 age group (37.45%). The most common adverse reactions involve skin and subcutaneous tissue disorders (36.34%), including skin swelling, pain, and burning sensations. Reports on EPSOLAY indicate adverse reactions such as erythema, pruritus, and skin exfoliation, but no tumor-related reports have been recorded.

Conclusions

BPO usage in dermatological aesthetics is associated with various adverse reactions, primarily affecting the skin. The introduction of EPSOLAY has not altered the adverse reaction profile significantly. However, the risk of BPO decomposing into the carcinogen benzene under certain conditions necessitates enhanced patient education, improved production processes, and continuous post-marketing surveillance to ensure drug safety.

背景:过氧化苯甲酰(BPO)广泛应用于皮肤美容,用于治疗痤疮和其他皮肤疾病。然而,其潜在的不良反应仍然令人担忧。目的:本研究旨在探讨BPO在皮肤美容中的应用,分析其相关不良反应,为患者安全提供见解。方法:分析2004 - 2024年美国食品药品监督管理局不良事件报告系统数据库中与BPO相关的不良反应报告。对新型药物EPSOLAY(5%微胶囊BPO)的人口统计学特征、不良反应类型和具体问题进行了研究。结果:BPO用户以女性为主(74.18%),其中18-44岁的用户占37.45%。最常见的不良反应包括皮肤和皮下组织紊乱(36.34%),包括皮肤肿胀、疼痛和烧灼感。关于EPSOLAY的报告显示不良反应,如红斑、瘙痒和皮肤脱落,但没有肿瘤相关的报告记录。结论:BPO在皮肤美学中的使用与各种不良反应相关,主要影响皮肤。EPSOLAY的引入并未显著改变不良反应概况。然而,在某些条件下,BPO分解为致癌物苯的风险需要加强患者教育,改进生产工艺,并持续进行上市后监测,以确保药物安全。

Background

Aging reduces the production of hyaluronic acid (HA) in the skin, leading to wrinkles and sagging. HA-based skincare products are being studied to improve skin quality. This systematic review and meta-analysis aimed to compare the effectiveness of HA-based injectable products for reducing wrinkles and enhancing skin elasticity, hydration, and radiation.

Methods

Eligible trial reports were found by searching PubMed, Embase, Scopus, and Web of Science systematically until May 2024. A random-effects meta-analysis was performed to evaluate the effect of HA injection on skin aging. The protocol of the study has been registered in PROSPERO with a registration ID of CRD42024540703.

Results

Overall, 12 studies met the inclusion criteria, of which 6 studies had enough data for meta-analysis. The random-effect meta-analysis showed improved hydration (SMD = 1.34, 95% CI = 0.14–2.54, and p < 0.05) and radiance (SMD = 0.51, 95% CI = 0.22–0.80, and p < 0.05) after HA filler injection. However, there was no significant difference in elasticity (SMD = 0.25, 95% CI = −0.20–0.70, and p = 0.27) and melanin index (SMD = −1.74, 95% CI = −4.89–1.41, p = 0.28) compared to controls.

Conclusions

According to the results of a meta-analysis, hyaluronic acid injections have been found to improve skin hydration and radiance, thus reversing the effects of skin aging. However, the study did not find any significant changes in the skin's elasticity or melanin index. Further research is required to confirm the effectiveness of hyaluronic acid in treating skin aging.

背景:衰老会减少皮肤中透明质酸(HA)的产生,导致皱纹和下垂。人们正在研究以ha为基础的护肤品,以改善皮肤质量。本系统综述和荟萃分析旨在比较基于ha的注射产品在减少皱纹和增强皮肤弹性、水合作用和辐射方面的有效性。方法:截止2024年5月,系统检索PubMed、Embase、Scopus和Web of Science,找到符合条件的试验报告。随机效应荟萃分析评估透明质酸注射对皮肤老化的影响。本研究方案已在PROSPERO注册,注册ID为CRD42024540703。结果:总的来说,12项研究符合纳入标准,其中6项研究有足够的数据进行meta分析。随机效应荟萃分析显示,注射透明质酸可以改善皮肤的水合作用(SMD = 1.34, 95% CI = 0.14-2.54, p)。结论:根据荟萃分析的结果,注射透明质酸可以改善皮肤的水合作用和光泽,从而逆转皮肤衰老的影响。然而,该研究并未发现皮肤弹性或黑色素指数有任何显著变化。透明质酸治疗皮肤老化的有效性还需要进一步的研究来证实。

Background: Tear trough deformities are indicative of aging, progressively manifesting as pronounced infraorbital hollows. Although hyaluronic acid (HA) dermal fillers are favored for their safety and efficacy, quantifiable evidence of their effect of action still remains insufficient.

Aims: To investigate the efficacy of non-cross-linked HA compound in tear trough enhancement.

Methods: Twenty-one subjects with moderate to severe infraorbital hollows underwent a single treatment including subcutaneous to supraperiosteal injections of a non-cross-linked HA compound. The effectiveness was assessed through Allergan Infraorbital Hollows Scale (AIHS), satisfaction rates, the Global Aesthetic Improvement Scale (GAIS), and quantitative analyses via Canfield VECTRA 3D imaging and MRI measurements during the 6-month follow-up.

Results: A total of 0.67 ± 0.31 and 0.77 ± 0.42 mL of the non-cross-linked HA compound were injected into the left and right suborbital regions, respectively. Substantial improvements in AIHS were observed in 85.71% and 80.95% of subjects at 6 months posttreatment, as assessed by blinded evaluators and treating investigators, respectively. 3D imaging showed volume increases of 0.87 ± 0.32 (left) and 0.99 ± 0.45 mL (right). MRI analysis provided closely aligned results to the 3D analysis. The GAIS and satisfaction rate were 85.71%, 90.48% for treating investigators and were 90.48% and 95.24% for subjects 6 months posttreatment.

Conclusions: The non-cross-linked HA filler demonstrated a safe and efficacious profile for the correction of infraorbital hollows with significant patient satisfaction and sustained outcomes up to 6 months posttreatment.

Purpose

To compare the postoperative scarring, complication rates, and efficacy between the hydrosurgery system and traditional single-incision surgical techniques for treating axillary osmidrosis.

Methods

A retrospective collection was conducted of all patients who underwent radical surgery for axillary osmidrosis at the Day Surgery Unit of the Department of Plastic Surgery at the First Affiliated Hospital of the Army Medical University from January 2023 to January 2024. Patients were screened based on inclusion and exclusion criteria and divided into the hydrosurgery group and the traditional surgery group. The evaluation was done through medical records, follow-up records, electronic questionnaires, and photographs. Assessments included 6-month postoperative scarring conditions, comprehensive effectiveness scores, postoperative odor/hair/sweating scores, postoperative dermatological life quality scores, and complication rates.

Results

A total of 73 patients completed this study: 34 in the hydrosurgery group and 39 in the traditional surgery group. 6 months postoperatively, the hydrosurgery group had significantly lower scores of the Vancouver Scar Scale (VSS), 0.5 (range 0.0–2.0) compared with 1.5 (range 0.5–3.0) in the traditional surgery group (p = 0.018). The incidence of complications such as subcutaneous hematoma, epidermal necrosis, and wound dissidence was also lower (26.5% vs. 51.3%, p = 0.031). Additionally, the surgical incision length in the hydrosurgery group was significantly smaller than in the traditional surgery group (1.200 cm (1.000, 1.275) vs. 2.500 cm (2.500, 3.000), p < 0.001). There were no significant differences between the two groups regarding comprehensive effectiveness scores, postoperative odor/hair/sweating scores, postoperative dermatological life quality index, and surgical duration.

Conclusion

Compared with traditional single-incision surgical techniques, patients in the hydrosurgery group exhibited lower scar scores 6 months postsurgery, required smaller surgical incisions, and had lower rates of surgical complications. Thus, the hydrosurgery is suitable for the minimally invasive surgical treatment of axillary osmidrosis, offering a safe, effective, and aesthetically superior treatment method.

目的:比较水手术系统与传统单切口手术技术治疗腋窝积液的术后瘢痕、并发症发生率及疗效。方法:回顾性收集2023年1月至2024年1月在陆军军医大学第一附属医院整形外科日间外科行根治性腋窝积臭手术的所有患者。根据纳入和排除标准对患者进行筛选,分为水手术组和传统手术组。通过病历、随访记录、电子问卷和照片进行评估。评估包括术后6个月疤痕状况、综合疗效评分、术后气味/毛发/出汗评分、术后皮肤生活质量评分和并发症发生率。结果:共73例患者完成本研究,其中水手术组34例,传统手术组39例。术后6个月,水手术组温哥华疤痕量表(VSS)得分为0.5分(范围为0.0 ~ 2.0),显著低于传统手术组的1.5分(范围为0.5 ~ 3.0)(p = 0.018)。皮下血肿、表皮坏死、创面不一致等并发症的发生率也较低(26.5%比51.3%,p = 0.031)。此外,水手术组的手术切口长度明显小于传统手术组(1.200 cm (1.000, 1.275) vs. 2.500 cm(2.500, 3.000)。p结论:与传统单切口手术技术相比,水手术组患者术后6个月瘢痕评分较低,手术切口较小,手术并发症发生率较低。因此,水手术适合于腋窝积臭的微创手术治疗,提供了一种安全、有效、美观的治疗方法。

<p>An 86-year-old woman presented with a rapidly growing right facial mass of more than 1 year duration, associated with bleeding, crusting, and occasional pain. Physical examination revealed an 8.0 cm × 8.0 cm mass on the right side of the face with clear margins, mild ulceration, and exudation (Figure 1A). Mild ectropion of the right eyelid was noted. Imaging studies showed no evidence of metastasis. Laboratory tests revealed that blood cell counts and coagulation function tests, including PT, APTT, INR, and D-dimer, were within normal limits. In addition, LDH, an important prognostic marker for various tumors, was measured at 131 U/L, also within the normal range [<span>1</span>]. Based on the tumor size and the absence of distant metastases, the clinical stage was determined to be T3NxM0 [<span>2</span>]. Given the patient's age and tumor size, wide local excision (WLE) with a 6 mm margin was performed. However, due to the proximity of the tumor to the orbit, it was difficult to achieve a 6 mm margin in this area and the final margin was 2–4 mm (Figure 1B). Postoperative pathology revealed a moderately to poorly differentiated cutaneous squamous cell carcinoma (cSCC) with no evidence of perineural invasion (PNI) (Figure 1D,E). Immunohistochemistry showed positive staining for CK5/6, p40, Ki67, and p63 (Figure 2). Residual tumor cells were also found around the cutting edge. The wound surface was treated with three consecutive sessions of photodynamic therapy (PDT) starting on postoperative day 2, with each session separated by 1 week. It was treated locally with 20% 5-aminolaevulinic acid (ALA) cream, followed by the application of a dark saran wrap for 3 h. Narrowband red light with a wavelength of 633 ± 10 nm was then applied at an intensity of 150 J/cm<sup>2</sup>. Each irradiation session lasted approximately 20 min, depending on patient tolerance. Secondary intentional healing (SIH) was chosen for reconstruction, with moist dressings used to facilitate wound healing. Dressings were changed every 2–3 days, starting with a layer of oil emulsion dressing mixed with antibiotic ointment, followed by clean gauze until wound healing was completed.

Introduction

In recent years, the field of aesthetic dermatology has witnessed a surge in demand for minimally invasive procedures aimed at rejuvenating aging skin. This study aims to address this demand by evaluating the effectiveness of the injectable gel in rejuvenating aging skin, particularly by targeting collagen regeneration and lifting effect.

Materials and Methods

The study involved 43 participants who underwent three monthly injection sessions targeting retaining ligaments. The injections were administered deeply to ensure proper targeting. Follow-up assessments were conducted after each treatment session and three months after the final injection. Evaluation methods included subjective assessments by both patients and investigators using the Global Aesthetic Improvement Scale (GAIS), as well as objective assessments using a 3D photosystem to measure wrinkle conditions and vectors of traction.

Results

All participants completed the study, with no significant adverse effects observed apart from mild swelling at the injection sites. Despite the high viscosity of HA necessitating the use of a 27 G needle, the injection process was generally comfortable and minimally painful. Subjective evaluations revealed consistent improvements in skin appearance from the first application, which continued to increase throughout the study and remained high even 3 months post-treatment. Objective evaluations demonstrated significant improvements in wrinkle conditions and lifting effects, with a substantial increase in the standard deviation score for wrinkle conditions and the average traction vector length measuring 1.6 mm.

Conclusion

The study findings confirm the safety and efficacy of the injectable formula, with high patient satisfaction, noticeable lifting effects, and significant improvements in wrinkle conditions. These results support the use of the injectable as a promising option for non-invasive skin rejuvenation treatments.

简介:近年来,美容皮肤病学领域见证了对旨在恢复衰老皮肤的微创手术的需求激增。本研究旨在通过评估可注射凝胶在恢复衰老皮肤中的有效性来解决这一需求,特别是针对胶原蛋白再生和提升效果。材料和方法:该研究涉及43名参与者,他们每月接受3次针对保留韧带的注射。注射是深入进行的,以确保正确的目标。在每次治疗后和最后一次注射后三个月进行随访评估。评估方法包括由患者和研究人员使用全球美学改善量表(GAIS)进行主观评估,以及使用3D光系统测量皱纹状况和牵引矢量进行客观评估。结果:所有参与者都完成了研究,除了注射部位轻度肿胀外,没有观察到明显的不良反应。尽管透明质酸的高粘度需要使用27g针头,但注射过程总体上是舒适的,并且疼痛最小。主观评价显示,自第一次应用以来,皮肤外观持续改善,在整个研究过程中持续增加,甚至在治疗后3个月仍保持较高水平。客观评价显示皱纹状况和提升效果显著改善,皱纹状况的标准差得分大幅增加,平均牵引矢量长度为1.6 mm。结论:研究结果证实了注射配方的安全性和有效性,患者满意度高,提皱效果明显,皱纹状况明显改善。这些结果支持使用注射作为一个有前途的选择,非侵入性皮肤再生治疗。
