Accuracy and safety of dry needle placement in the piriformis muscle in cadavers

Objectives: The purpose of this anatomic investigation is to (1) establish accuracy of dry needle placement into the medial third of the piriformis muscle as it exits the pelvis from the greater sciatic notch in unembalmed cadaveric specimens, while avoiding puncture of the sciatic nerve, and (2) establish guidelines for dry needle length selection.

Methods: Dry needles were placed in nineteen unembalmed cadaveric posterior hips. Dissection of the posterior hip musculature was performed to confirm location of the needle. A binary decision (yes/no) was made to determine whether the needle reached the piriformis muscle, went through the piriformis muscle, and/or pierced the sciatic nerve. Additionally, mean adipose tissue thickness, gluteus maximus muscle thickness, and perpendicular distance from the needle to the exiting sciatic nerve were recorded.

Results: The needle reached the medial third of the piriformis in 16 out of 19 hips (84.2% accuracy) and never punctured the sciatic nerve. There was a fair (r = 0.493) and good (r = 0.759) correlation between the needle length and the mean fat thickness for the left and right hips, respectively.

Discussion: A physical therapist was able to use bony landmark palpation to locate the piriformis muscle and use estimated adipose tissue thickness to choose a sufficient needle length to reach the medial third of the piriformis muscle. While the needle placement technique was safe and no sciatic nerve puncture occurred, the proximity of the piriformis muscle to the sciatic nerve warrants caution during needle placement.

Application of the ISTH bleeding score in hemophilia

Background

Hemophilia is an inherited bleeding disorder. With proper treatment and self-care, persons with hemophilia can maintain an active, productive lifestyle. Hemophilia can be mild, moderate, or severe, depending on the degree of plasma clotting factor deficiency. The aim of the study was to assess the utility of ISTH-BAT in diagnosis, determining severity of the bleeding condition in newly diagnosed and known hemophilia patients, compare the bleeding score (BS) in adult and pediatric groups and investigate its association with plasma factor levels.

健脾通腑方序贯联合生长抑素治疗急性胰腺炎对TREM-1水平和胰腺功能的影响分析

【】目的 分析健脾通腑方序贯联合生长抑素治疗急性胰腺炎对髓样细胞触发受体-1(TREM-1)水平和胰腺功能的影响。方法 回顾性选取2015年12月至2018年1月我院收治的急性胰腺炎患者106例,根据治疗方法不同分为对照组和观察组。对照组患者采用常规治疗联合生长抑素治疗,观察组患者加用健脾通腑方序贯治疗,分析两组患者治疗后的临床效果。结果 治疗前,两组患者中医症状积分水平比较,差异无统计学意义(P>0.05)。治疗后,观察组患者中医症状积分水平低于对照组,差异有统计学意义(P<0.05)。治疗前,两组患者TREM-1、内皮素(ET)、C反应蛋白(CRP)、胰腺功能指标水平比较,差异无统计学意义(P>0.05)。治疗后,观察组患者正铜蓝蛋白(CP)、胰岛素(INS)水平高于对照组,TREM-1、ET、CRP、胰蛋白酶原-2(TPS-2)、脂肪酶(LIP)水平低于对照组,差异有统计学意义(P<0.05)。观察组患者中转手术率低于对照组,血淀粉酶恢复时间、腹痛缓解时间及住院时间短于对照组,差异有统计学意义(P<0.05)。结论 健脾通腑方序贯联合生长抑素治疗急性胰腺炎可降低患者TREM-1、ET、CRP水平,改善患者胰腺功能,缩短住院时间。

The HAS-Choice study: Utilizing the HEART score,an ADP,and shared decision-making to decrease admissions in chest pain patients

Objective

The HAS-Choice pathway utilizes the HEART Score, an accelerated diagnostic protocol (ADP), and shared decision-making using a visual aid in the evaluation of chest pain patients. We seek to determine if our intervention can improve resource utilization in a community emergency department (ED) setting while maintaining safe patient care.

举臂拧螺丝作业肩腕部肌电特征与工具重量的相关性

目的应用表面肌电(s EMG)描记技术分析汽车装配作业工人手臂用不同重量工具拧螺丝作业过程中肩部、腕部肌肉的肌电信号特征,初步探讨其与重量负荷的相关性。方法选择某汽车厂总装线7名男性工人为研究对象,采用Biovision表面肌电仪采集受试者进行正常装配活动时右侧三角肌和前臂腕屈肌群的表面肌电信号;应用DASYLab10.0数据处理软件和SPSS16.0统计分析软件,对肌电时域指标RMS和频域指标MF与工具重量的相关性进行统计分析。结果研究对象使用的工具涉及3个重量,分别为0.2 kg、1 kg和1.35 kg。在前臂腕屈肌群工具重量与最大自主收缩百分比(MVE%)和MF均呈负相关,相关系数分别为-0.430和-0.569(P0.01);在三角肌与MVE%和MF分别呈正相关和负相关,相关系数分别为0.598和-0.376(P0.01)。结论在举臂拧螺丝作业中,肩腕部局部肌肉MVE%和MF的变化可反映工具重量的大小。
