简介:AbstractPeriprosthetic joint infection (PJI) is the most difficult complication following total joint arthroplasty. Most of the etiological strains, accounting for over 98% of PJI, are bacterial species, with Staphylococcus aureus and Coagulase-negative staphylococci present in between 50% and 60% of all PJIs. Fungi, though rare, can also cause PJI in 1%—2% of cases and can be challenging to manage. The management of this uncommon but complex condition is challenging due to the absence of a consistent algorithm. Diagnosis of fungal PJI is difficult as isolation of the organisms by traditional culture may take a long time, and some of the culture-negative PJI can be caused by fungal organisms. In recent years, the introduction of next-generation sequencing has provided opportunity for isolation of the infective organisms in culture-negative PJI cases. The suggested treatment is based on consensus and includes operative and non-operative measures. Two-stage revision surgery is the most reliable surgical option for chronic PJI caused by fungi. Pharmacological therapy with antifungal agents is required for a long period of time with antibiotics and included to cover superinfections with bacterial species. The aim of this review article is to report the most up-to-date information on the diagnosis and treatment of fungal PJI with the intention of providing clear guidance to clinicians, researchers and surgeons.
简介:在这篇文章,合成关节在把负担弄弯下面被调查。L预先形成是关于合成联合失败的批评部件。学习在在弯曲下面的合成联合结构装载使用纤维布拉格的碳纤维的失败察觉被介绍栅栏(FBG)传感器。第一,基于一般有限元素方法(女性)软件,3-D合成关节的有限元素(FE)模型被建立,并且失败进程和合成关节的每薄板失败负担被最大的压力标准调查。然后,沿着FBG的长度的紧张分布被提取,并且FBG的思考系列根据紧张分发是计算的。最后,验证数字结果,一个测试计划被执行,FBG的试验性的系列被记录。试验性的结果显示失败定序并且相应批评大量失败与数字预言一致,并且失败负担的计算错误是不到6.4%。而且,它也验证损坏察觉系统的可行性。
简介:客观:为了探索颈的方面关节的神经分布的模式并且从方面关节决定小径到背面的根中心(DRG)以便澄清,膜弥漫的颈疼痛,头疼,和肩膀疼痛使用。方法:42男Sprague-Dawleyrats,称250-300g,随机被划分成三个组:组A(n=18),组B(n=18),和组C(n=6)。在有intraperitonealpentobarbital钠(45mg/kg身体重量)的麻醉下面,背面的纵的切口在颈的脊骨上被做在一台显微镜下面暴露所有老鼠的左颈的方面关节囊的一条中线。在组A的老鼠在组B和组C经历了交感神经切除术,而是老鼠没经历交感神经切除术。然后,0.6μl5%bisbenzimide(Bb)被注入C_(1-2),C_(3-4)和方面在组A和组B分别地6只老鼠连接的C_(5-6)。洞立即与矿物质蜡被封上阻止Bb和扁带的漏,皮被闭上。但是在组C,0.9%正常盐被注入相应的联合的囊。然后在有intraperitonealpentobarbital钠(45mg/kg身体重量)的深重新麻醉下面,在所有老鼠的C_1-C_8左DRG和在组B的同情的中心被获得,标记的神经原的数字是坚定的。结果:用Bb标记的神经原在组B在在组A和组B,和同情的中心的C_1-C_8DRG是在场的。在C_(1-2)和C_(3-4)亚群,标记的神经原从C_1toC_8DRG是在场的,当在C_(5-6)亚群他们从C_3到C_8时。没有交感神经切除术,在交感神经切除术以后的Bb(+)神经原的数字不在从那的注射水平是显著地不同的。但是在其它铺平,在交感神经切除术以后的Bb(+)神经原的数字是显著地不到那没有交感神经切除术。结论:颈的方面关节的神经分布从感觉、同情的神经系统被导出,并且DRG在中央神经系统外面通过神经纤维与同情的中心被联系。
