Nerve hydrodissection for carpal tunnel syndrome: A prospective,randomized, double-blind,controlled trial

Introduction: In this study we explored the efficacy of nerve hydrodissection for mild-to-moderate carpal tunnel syndrome (CTS). Methods: Thirty-four participants were randomly assigned to an intervention group or a control group. One 5-ml dose of normal saline was injected into the intracarpal and subcutaneous regions in subjects of both groups, respectively. The primary outcome measure was the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) score. Secondary outcomes were cross-sectional area of the median nerve and electrophysiological studies. Assessments were performed before the injection and at 1, 2, 3, and 6 months postintervention. Results: Compared with the control group, the intervention group showed significantly greater improvement at the second and third posttreatment months according to BCTQ severity score and at all time-points for cross-sectional area of the median nerve (P < 0.01). Discussion: Our study demonstrates the therapeutic effects of nerve hydrodissection for mild-to-moderate CTS. Muscle Nerve 59 :174–180, 2019     

星点设计-效应面法优化丁香苦苷聚乳酸-羟基乙酸纳米粒的制备工艺

目的优化丁香苦苷聚乳酸(Syr)-羟基乙酸共聚物[poly(lactic-co-glycolic acid),PLGA]纳米粒(Syr-NPs)的处方。方法采用纳米沉淀法制备Syr-NPs,以包封率、载药量、平均粒径以及总评"归一值"为评价指标,采用星点设计-效应面法考察PLGA质量浓度(A)、丁香苦苷质量浓度(B)、水相与有机相比例(C)3因素考察对包封率、载药量、平均粒径以及总评归一值的影响,以星点设计-效应面法选取最佳处方条件进行预测分析。结果最优处方工艺为PLGA质量浓度为9.63 mg/mL,Syr质量浓度为12.88 mg/mL,有机相与水相的比例为1∶9.46,制得的Syr-NPs的包封率、载药量、平均粒径分别为(27.86±0.87)%、(7.02±0.15)%、(110.0±1.20)nm。结论该方法稳定可行,可用于优化包载Syr的PLGA纳米粒处方与制备工艺。     

Logistical and Economic Advantages of Sterile-Packed,Single-Use Instruments for Total Knee Arthroplasty

BackgroundTotal knee arthroplasty (TKA) is well established as a clinically successful and cost-effective procedure. The transition of the US healthcare system from a fee-for-service model to a value-based care model requires careful examination of patient care to ensure both quality and efficiency. Sterile-packed, single-use instruments have been introduced as a tool to help streamline the operating room (OR) logistics while reducing sterilization requirements. The aim of this study was to examine the potential logistic and economic benefits of single-use instruments compared to traditional, reusable instruments for TKA.MethodsFour variables related to TKA costs and logistics were modeled in this study: OR turnover time tray sterilization, tray management time, and 90-day infection rates. Model input data for traditional instruments and single-use instruments were based on peer-reviewed literature. A total of 200 sites and 500 cases per site were simulated using the Monte-Carlo-Technique.ResultsThe median total cost savings with single-use instruments was $994 per case. The largest driver for cost savings was tray sterilization. Sites with higher staff wages and sterilization costs had a larger probability of realizing greater cost savings with adoption of single-use instruments. In cases using single-use instruments, up to 51% of operating days could have accommodated an additional procedure due to the time savings in OR turnover.ConclusionThis cost modeling study observed significant potential for logistical and economic improvements in TKA with single-use vs reusable instruments. Although few studies have been conducted to measure the impact of single-use instruments in practice, the results of these simulations motivate further investigation.
