    为了解决局部应用伊维菌素(IVM)经常观察到的皮肤反应,进行了一项研究,以开发和优化负载有IVM的跨酶体(TESM),以治疗c疮.三因素,采用两级(23)全因子设计。大豆磷脂酰胆碱浓度(A),乙醇浓度(B)和跨度60量(C)作为独立因素进行了研究,而截留效率(EE),粒度(PS),多分散指数(PDI),zeta电位(ZP)和药物释放后6h(Q6h)进行了表征。通过皮肤刺激试验和组织病理学检查评价优化制剂的皮肤敏感性。EE%范围从88.55±0.576%到94.13±0.305%,PS为318.033±45.61nm至561.400±45.17nm,PDI为0.328±0.139至0.671±0.103,ZP为-54.13±1.09mV至-60.50±2.34mV,Q6h为66.20±0.30%至93.46±0.86%。加载IVM的跨卵巢乳膏显示出更低的皮肤刺激和更完整的表皮层与完整的角质形成细胞,与市场上显示角蛋白层严重破坏的奶油相比。因此,可以通过将IVM封装在TESM中以最小化其皮肤反应来改善患者的依从性。
    In an effort to tackle the skin reactions frequently observed with topical application of ivermectin (IVM), a study was conducted to develop and optimize transethosomes (TESMs) loaded with IVM for scabies treatment. A three-factor, two-level (23) full factorial design was employed. Soyabean phosphatidylcholine concentration (A), ethanol concentration (B) and Span 60 amount (C) were studied as independent factors, while entrapment efficiency (EE), particle size (PS), polydispersity index (PDI), zeta potential (ZP) and drug release after 6 h (Q6h) were characterized. The skin sensitivity of the optimized formulation was evaluated by skin irritation test and histopathological examination. The EE% ranged from 88.55 ± 0.576% to 94.13 ± 0.305%, PS was from 318.033 ± 45.61 nm to 561.400 ± 45.17 nm, PDI was from 0.328 ± 0.139 to 0.671 ± 0.103, ZP was from -54.13 ± 1.09 mV to -60.50 ± 2.34 mV and Q6h was from 66.20 ± 0.30% to 93.46 ± 0.86%. The IVM-loaded transethosomal cream showed lower skin irritation and a more intact epidermal layer with intact keratinocyte, compared to the marketed cream which showed severe destruction of the keratin layer. Therefore, patient compliance can be improved by encapsulating IVM within TESMs to minimize its skin reactions.

    镰刀菌是皮肤的寄生虫侵染,在拥挤的空间中患病率很高。在某些情况下,sc疮成为儿童和成人复杂的皮肤传播的机会性病原体感染的潜在因素。地理区域和社会经济因素是这种疾病流行模式的决定因素。目前,sc疮的治疗一直受到特别关注。口服治疗与伊维菌素和硫基软膏的组合是金标准。然而,肾损害患者需要谨慎。儿童sc疮的肾脏受累主要是由急性肾小球肾炎引起的。肾病综合征的严重程度可导致其他并发症。此外,伊维菌素具有肾毒性作用。严重的高血压可导致神经系统并发症。我们的病例报告的目的是在sc疮兄弟中提出两种不寻常的并发症。我们报告了两兄弟sc疮的病例,这些病例表现为严重的皮肤感染,发展为急性感染性后肾小球肾炎(APIGN)。此外,其中一个兄弟出现了后部可逆性脑病综合征(PRES)。另一个在伊维菌素给药后发展为急性小管间质性急性肾损伤。皮肤病变的演变是有利的,两个兄弟的肾功能都恢复正常了.
    Scabies is a parasitic infestation of the skin with high prevalence in crowded spaces. In some instances, scabies becomes the underlying factor for complicated skin-borne opportunistic pathogens infections in both children and adults. Geographic area and socio-economic factors are determinants of the endemic pattern of this disease. Currently, the treatment of scabies has been under special attention. A combination of oral therapy with Ivermectin and sulfur-based ointments are the gold standard. However, caution is required in patients with kidney impairment. The renal involvement in children with scabies is mainly caused by acute glomerulonephritis. The severity of the nephritic syndrome can lead to other complications. Also, Ivermectin possesses a nephrotoxic effect. Severe hypertension can lead to neurological complications. The aim of our case report is to present two unusual complications in brothers with scabies. We report the cases of two brothers with scabies who presented with severe skin infection that developed acute post infectious glomerulonephritis (APIGN). In addition, one of the brothers presented with posterior reversible encephalopathy syndrome (PRES). The other one developed acute tubule-interstitial acute kidney injury following Ivermectin administration. The evolution of skin lesions was favorable, and kidney function returned to normal in both brothers.

    背景:镰刀通过其高度令人不安的疾病症状破坏生活质量,通过扭曲自我感知,仅次于社会耻辱。了解其对一般生活质量和日常生活特定方面的影响是满足个体患者健康需求和评估社区疾病控制干预措施收益的关键。
    目的:评估sc疮对感染患者生活质量的影响。
    方法:一项基于社区的横断面研究是在埃塞俄比亚西北部一个受sc疮暴发影响的地区进行的。该研究涉及381个家庭和86名sc疮成年人。我们使用了十项卡迪夫皮肤病学生活质量指数(DLQI)工具来收集数据。Cronbach的alpha值用于确定Amharic版本的量表的内部一致性。计算总体和皮肤病学生活质量(DLQ)领域特异性平均得分。使用Kruskal-Wallis检验检验了社会人口统计学特征与c疮相关生活质量损害之间的关联。
    结果:of疮中度影响成人of疮的生活质量。总平均DLQI(mDLQI)评分为9.2(SD=7.6)。“症状和感觉”和“日常活动”DLQ域的mDLQI得分最高(分别为3.5,SD=1.9和2.2,SD=2.5)。“休闲活动”是受影响最小的域0.8(SD=1.1)。就严重程度而言,54.7%的参与者对DLQ有中度或重度影响,27%的参与者报告有极其严重的影响.然而,未观察到社会人口统计学特征与生活质量损害之间的关联.
    结论:在sc疮患者中,生活质量受到中度损害。重新将注意力集中在疾病症状的管理上,使用标准的sc疮治疗,并提供心理社会支持,以改善患者的自我认知,可能有助于减少生活质量的损害。
    BACKGROUND: Scabies undermines quality of life through its highly disturbing disease symptoms, by distorting self-perception, and secondary to social stigma. Knowledge of its effect on quality of life in general and on specific aspects of day-to-day life is key to addressing the health needs of individual patients and to evaluating gains from community-based disease control interventions.
    OBJECTIVE: To measure the effect of scabies on the quality of life of people with the infestation.
    METHODS: A community-based cross-sectional study was conducted in a scabies outbreak-affected district in north-western Ethiopia. The study involved 381 households and 86 adults with scabies. We used the ten-item Cardiff Dermatology Life Quality Index (DLQI) tool to collect data. Cronbach\'s alpha value was used to determine the internal consistency of the Amharic version of the scale. Overall and Dermatology Life Quality (DLQ) domain specific mean scores were calculated. The association between sociodemographic characteristics and scabies-related life quality impairment was tested using Kruskal-Wallis test.
    RESULTS: Scabies moderately affected the quality of life of adults with scabies. The overall mean DLQI (mDLQI) score was 9.2 (SD = 7.6). \'Symptoms and feelings\' and \'daily activity\' DLQ domains had the highest mDLQI scores (3.5, SD = 1.9 and 2.2, SD = 2.5, respectively). \'Leisure activities\' was the least affected domain 0.8 (SD = 1.1). In terms of severity, scabies had moderate or severe effect on DLQ of 54.7% of the participants and extremely severe effect was reported among 27% of the participants. However, no association was observed between sociodemographic characteristics and quality of life impairment.
    CONCLUSIONS: Quality of life was moderately impaired among people affected by scabies. Refocusing attention on management of disease symptoms, using standard scabies treatment, and providing psychosocial support to improve self-perception of people affected with scabies may help reduce quality of life impairment.

    镰刀是由洞穴螨引起的皮肤瘙痒疾病,Sarcoptesscabiei.在他们的生命中,雌性螨虫侵入角质层并形成它们居住的隧道,移动,饲料,沉积粪便颗粒,产卵。全球范围内,据估计,每年有超过2亿人受到sc疮的影响。目前,使用杀菌剂是唯一被批准的治疗sc疮的方法。然而,对氯氯菊酯和伊维菌素等常用药物的抗性已在sc虫中观察到。因此,开发针对sc疮的疫苗,作为预防措施或治疗,对于控制这些被忽视的疾病至关重要。由于宿主可以进化出保护性的免疫反应,可以防止sc虫再次侵染,疫苗开发在理论上是可能的。本审查旨在全面概述当前可用的sc疮控制措施的持续挑战。它还探索了sc疮疫苗开发的有希望的道路,强调当前的研究状况和需要解决的挑战,以开发新的和创新的措施来治疗和预防sc疮感染。
    Scabies is an itchy skin disease caused by the burrowing mite, Sarcoptes scabiei. During their lifespan, female mites invade the stratum corneum and create tunnels in which they reside, move, feed, deposit fecal pellets, and lay eggs. Globally, more than 200 million people are estimated to be affected by scabies annually. Currently, using scabicidal agents is the only approved method for treating scabies. However, resistance to commonly used agents such as permethrin and ivermectin has been observed in scabies mites. Therefore, the development of vaccines for scabies, either as a preventative measure or for treatment, is crucial to control such neglected diseases. Since the host could evolve a protective immune response that could prevent re-infestation by scabies mites, vaccine development is theoretically possible. This review aims to provide a comprehensive overview of the ongoing challenges regarding the currently available control measures for scabies. It also explores the promising path of scabies vaccine development, highlighting the current state of research and challenges that need to be addressed to develop new and innovative measures for both treating and preventing scabies infections.

    妄想侵染(DI)描述了一种固定的,错误的信念,即一个人认为他们感染了活的或无生命的病原体,尽管没有医学证据证明这种感染。对所谓病原体的描述随着时间的推移而演变,结合无生命的物体,如纤维束。随着Morgellons病的出现及其争议,我们报告了一例40岁的女性,表现出强烈的sc疮感染信念,并从皮肤中露出纤维。Further,尽管昆虫仍然是最据称的侵扰源,Morgellons病的重叠和侵扰的妄想支持它作为DI变体,并质疑其作为独立诊断实体存在的概念。
    Delusional infestation (DI) describes a fixed, false belief where a person believes that they are infested with living or inanimate pathogens despite the absence of medical evidence for such infestation. Descriptions of alleged pathogens have evolved over time, incorporating inanimate objects such as fibrous strands. With the emergence of Morgellons disease and its controversy, we report a case of a 40-year-old female presenting with a strong belief of scabies infestation along with fibers emerging from her skin. Further, although insects are still the most alleged source of infestation, the overlap of Morgellons disease and the delusion of infestation supports it as a DI variant and questions the notion of its existence as a separate diagnostic entity.

    背景:由于过分拥挤的生活条件和有限的医疗保健资源,在监狱中,镰刀是一个普遍存在的问题。最近发表在《感染与公共卫生杂志》上的一项研究发现,在不同地区和设施的囚犯中,sc疮的患病率差异很大。本综述旨在通过进行系统评价和荟萃分析来确定囚犯中sc疮的全球患病率和预测因素。
    方法:我们遵循系统评价和荟萃分析检查表的首选报告项目来报告我们的系统评价和荟萃分析的结果。相关数据库,包括PubMed,科克伦图书馆,ScienceDirect,和其他灰色文献数据库被用来搜索和检索文章。该研究包括以英语编写的已发表和未发表的研究,用于报告囚犯中人sc疮的患病率。此评论已在PROSPERO上注册。使用I2统计量评估数据的异质性。使用STATA17软件进行荟萃分析,95%的置信区间。研究人员还进行了发表偏倚和敏感性分析。
    结果:该综述包括7项研究,涉及1,309,323名囚犯。所有纳入的研究都涉及横断面研究设计。囚犯中sc疮的患病率从意大利的0.72%到喀麦隆的41.01%不等。囚犯中人类sc疮的全球合并患病率为6.57%(95%CI;2.16-19.94)。根据亚组分析,非洲囚犯sc疮的总体患病率为19.55%(95%CI;9.44-40.45),而非洲以外囚犯的患病率为1.57%(95%CI;0.77-3.19)。在监狱里度过的时间,分享衣服或床,和卫生习惯被发现是与囚犯发展为人类sc疮的可能性显着相关的因素。
    结论:在全世界的囚犯中,人类sc疮的总体患病率很高。在监狱里呆更多时间的囚犯共用衣服或床位,卫生习惯差的人更有可能患上sc疮。因此,政策制定者和计划管理者应努力降低监狱中sc疮的患病率。本系统评价和荟萃分析的方案已在国际前瞻性系统评价注册簿中注册,注册号为CRD42024516064。
    BACKGROUND: Scabies is a widespread issue in prisons due to overcrowded living conditions and limited healthcare resources. A recent study published in the Journal of Infection and Public Health discovered that the prevalence of scabies varies greatly among prisoners in different regions and facilities. This review aimed to determine the global prevalence and predictors of scabies among prisoners by conducting a systematic review and meta-analysis.
    METHODS: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis checklist to report the findings of our systematic review and meta-analysis. Relevant databases including PubMed, Cochrane Library, ScienceDirect, and other grey literature databases were used to search and retrieve articles. The study included both published and unpublished research written in English languages for studies reporting the prevalence of human scabies among prisoners. This review has been registered on PROSPERO. The heterogeneity of the data was evaluated using the I2 statistic. A meta-analysis was conducted using STATA 17 software, with a 95% confidence interval. The researchers also conducted publication bias and sensitivity analysis.
    RESULTS: The review included 7 studies involving 1, 309,323 prisoners. All included studies involved cross-sectional study design. The prevalence of scabies among prisoners ranges from 0.72% in Italy to 41.01% in Cameroon. The global pooled prevalence of human scabies among prisoners was found to be 6.57% (95% CI; 2.16-19.94). According to subgroup analysis, the overall prevalence of scabies among African prisoners was 19.55% (95% CI; 9.44-40.45), while the prevalence among prisoners outside of Africa was 1.57% (95% CI; 0.77-3.19). The length of time spent in prison, sharing of clothing or beds, and hygiene practices were found to be factors that were significantly associated with the likelihood of prisoners developing human scabies.
    CONCLUSIONS: The overall prevalence of human scabies is high among prisoners worldwide. Prisoners who spent more time in prison shared clothing or beds, and had poor hygiene practices were more likely to develop human scabies. Thus, efforts should be made by policymakers and program administrators to decrease the prevalence of scabies in prisons. The protocol for this systematic review and meta-analysis was registered in the International Prospective Register of Systematic Reviews with registration number CRD42024516064.

    Sarcoptic或sc疮是一种传染性寄生性皮肤病,会影响各种家庭和野生动植物物种。进行了横断面研究以确定患病率,分子鉴定,以及维库尼亚斯的沙眼mange的特征。总共检查了3,274个维库尼亚。在13个安第斯社区举行的仪式收获活动(“chaccus”)之后。通过皮肤刮擦技术确定and螨的存在,并使用针对Sarcoptesscabiei的ITS2基因的特异性引物通过PCR分析进行确认。使用取自wallows的样品,通过显微镜也证实了螨螨的存在。使用数据收集表格来记录采样的维库尼亚斯的特征。沙眼manage的患病率为4.9%(95%CI:4.1-5.6%)。来自wallows的所有样品测试为阳性(9/9)。重要的是,在分子上证实了S.scabiei物种的存在。身体有规律的成年女性更容易受到沙眼的影响,虽然病变较轻。这项研究证实了半圈养的vicuñas中存在S.scabiei,并指出了walls在Sarcoptes螨传播中的可能作用。
    Sarcoptic mange or scabies is a contagious parasitic skin disease that affects a wide range of domestic and wildlife species. A cross-sectional study was carried out to determine the prevalence, molecular identification, and characteristics of sarcoptic mange in vicuñas. A total of 3,274 vicuñas were examined. Following ritual harvesting events (\"chaccus\") in 13 Andean communities. The presence of mange mites was determined by the skin scraping technique and confirmed by PCR analysis using specific primers for the ITS2 gene of Sarcoptes scabiei. The presence of mange mites was also confirmed by microscopy using samples taken from wallows. A data collection form was used to register the characteristics of the vicuñas sampled. The prevalence of sarcoptic mange was 4.9% (95% CI: 4.1 - 5.6%). All samples from wallows tested positive (9/9). Importantly, the presence of the species S. scabiei was molecularly confirmed. Adult females with regular body condition were more susceptible to sarcoptic mange, although the lesions were mild. This study confirms the presence of S. scabiei in semi-captive vicuñas and points to the possible role of wallows in the dissemination of Sarcoptes mites.
