Update on sports imaging

Sports Imaging has dramatically increased in the past decade with increasing number of adolescents, young and middle-aged adults participating in non-competitive/hobby sports. Therefore, sports injuries are no longer confined to elite athletes. Furthermore, newer forms of sports such as mountain climbing, pickle ball and curling etc. are gaining popularity. Majority of the injuries in sports medicine are from musculoskeletal trauma. Therefore, it is imperative that the musculoskeletal radiologist becomes familiar with various sports related injury patterns as these are commonly encountered in daily practice. This update aims to briefly encapsulate the major aspects of sports imaging. It includes the imaging manifestations of various types of musculoskeletal injuries on different modalities (commonly US and MRI) and briefly mentions the various image guided interventions, performed both on the sports field and in the hospital setting.     

Detrended fluctuation analysis detects altered coordination of running gait in athletes following a heavy period of training

Objectives

To investigate whether functional overreaching affects locomotor system behaviour when running at fixed relative intensities and if any effects were associated with changes in running performance.

2009-2019年西安市肺结核流行特征及治疗转归分析

目的 了解2009-2019年西安市肺结核的流行特征及治疗转归情况，为完善西安市肺结核防治策略提供依据。方法 收集2009-2019年《传染病信息管理系统》中登记的肺结核患者病案信息数据，通过描述性研究方法对肺结核流行病学特征和治疗转归情况进行分析。结果 2009-2019年间西安市肺结核年平均发病率为49.06/10万。郊县、郊区、城区肺结核年平均发病率分别为54.13/10万、47.46/10万和46.19/10万；男性发病率是女性的1.85倍。职业分布排在前5位的为农民（47.48%），家政、家务及待业（14.65%），离退人员（9.55%），学生（8.63%）和工人（5.23%）。利福平敏感或耐药性未知患者的成功治疗率平均为98.03%，利福平耐药患者治疗成功率为51.47%。结论 西安市近年来肺结核发病率和治疗率呈增长趋势，利福平耐药患者治疗成功率较低，要加强对重点人群的健康促进工作，加大肺结核发现力度及患者治疗管理工作。     

High-Pressure Water Swelling Sealant Injection Injury to the Hand: a Case Report and Review of the Literature

High-pressure injection injuries (HPII) caused by water swelling sealant are rare at present. The patient generally has small-sized skin lesions, and the misleadingly benign presentation may cause delayed treatment at the early stage of management. In addition, radiographic examination may be underestimated. Subsequently, the inadequate surgical intervention may cause tissue necrosis and poor prognosis. Furthermore, the early recognition of water swelling sealant injected into tissue and emergent surgical intervention are the key to successful management for the patient with HPII caused by injecting water swelling sealant to tissue.     

关节镜联合关节牵张成形术治疗踝关节创伤性关节炎

目的对比分析单纯关节镜手术与关节镜手术联合Ilizarov外固定架关节牵张术治疗踝关节创伤性关节炎的临床疗效。 方法纳入2016年10月至2018年4月聊城市中医医院收治的早中期踝关节创伤性关节炎患者30例，排除非创伤性关节炎和终末期踝关节炎。其中接受单纯踝关节镜手术者纳入对照组(n＝15)，接受关节镜手术联合Ilizarov外固定架关节牵张成形术者纳入研究组(n＝15)，术后随访6个月，对比分析两组患者的治疗效果：疼痛视觉模拟评分(VAS)、踝关节功能评分(Kofoed评分)以及生活质量的变化。计数资料比较采用卡方或Fisher精确检验，计量资料比较采用独立样本t检验。 结果研究组治疗有效率大于对照组(χ²＝7.214，P<0.05)，术后疼痛视觉模拟评分明显低于对照组(t ＝10.342，P<0.05)，Kofoed评分高于对照组(t ＝10.452，P<0.05)；研究组生活质量显著高于对照组(P<0.05)。 结论关节镜手术联合关节牵张成形术对早中期踝关节创伤性关节炎较单纯关节镜手术短期效果更好，可成为临床治疗中的一种选择，但远期效果尚需进一步研究。     

医用粘胶相关性皮肤损伤的文献计量学分析

目的: 应用文献计量学方法,分析国内外医用粘胶相关性皮肤损伤（Medical adhesive-related skin injuries,MARSI）文献的研究主题和热点。方法: 检索Cochrane Library、PubMed、EMbase、Web of science、sinoMed、CNKI、Wanfang、VIP等数据库MARSI相关文献,检索时限为建库至2019年5月。采用SPSS 22.0 软件进行文献计量分析,利用gCLUTO统计对国内外高频主题词进行聚类分析。结果: 共纳入论文103篇,其中外文文献占总文献量的27.18%,中文文献占总文献量的72.82%。聚类分析将国内外高频主题词聚为4大类,依次为皮肤损伤及损伤类型、相关危险因素、风险评估及风险管理、护理干预措施。结论: MARSI仍是国内外研究的热点,其发病机制研究仍处于探索阶段,目前尚缺乏有效的预防策略,研究领域较局限。在今后的研究中,应加强MARSI预防的研究、注重多学科合作。     

A comparison of head injuries in male and female lacrosse participants seen in US emergency departments from 2005 to 2016

Introduction

In the United States there has been a large increase in participation in lacrosse for both males and females. The purpose of this study was to analyze the number of head injuries, injury rates (calculated using the reported number of participants) and types of head injuries that are seen in emergency departments in the United States.
