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.     

空间频域成像在皮肤病定量评估中的研究

利用空间频域成像技术搭建的成像系统检测多种皮肤病组织的光学参数和生理参数信息，并对比分析讨论不同类型的皮肤病与光学参数、生理参数之间的关系。实验结果表明，病变皮肤组织与正常皮肤组织之间在光学参数、生理参数上存在较大差异，这将为临床医生对皮肤病诊治提供一种新颖、可靠、科学的评估方法。     

Étude exploratoire de la santé musculo-squelettique du rachis d’étudiants en ostéopathie

BackgroundDuring their training, students in osteopathy regularly undergo spinal manipulation exercises. This exposes the students’ spine to unskilled gestures performed by their colleagues learning spinal manipulation. Discomfort, muscle soreness or moderate pain following spinal manipulations lasting two or three days are commonly reported. In addition, some students may have ongoing spinal musculoskeletal disease (SMSD) during their studies. The purpose of this study was to evaluate the prevalence of SMSDs and their maximum intensity in a population of osteopathy students and to determine whether individual differences exist.MethodAn exploratory cross-sectional study took place over three years. Data were collected by means of a self-administrated standardised questionnaire screening for MSD: the Nordic questionnaire.ResultsThere were 733 exploitable questionnaires, giving an average response rate of 91.5%. Average prevalence of SMSD was 98.4% during the last 12 months. Average maximum intensity perceived was 6/10 and 45% of students experienced an intense SMSD (scored between 7 and 10/10). Variation of the maximum intensity of SMSD between “before osteopathy studies” and “the last 12 months” was 1.2/10. This variation was influenced by the number of days students were manipulated during a week (p < 0.0001). On average, students underwent manipulation three days a week.ConclusionThis study confirms the important prevalence of SMSD among osteopathy students. This result led us to carry out a qualitative study for exploring students’ conceptions in health and spinal manipulative practices.     

多巴胺或多巴胺复合去甲肾上腺素对肝移植术中患者血液动力学、氧代谢及肾功能的影响

目的评价原位肝脏移植术(OLT)中持续输注多巴胺或多巴胺复合去甲肾上腺素对血液动力学、组织氧代谢和肾功能的影响。方法拟行OLT的患者30例,ASAⅢ或Ⅳ级,随机分为2组 (n=15)。A组:术中持续输注多巴胺,初始输注速率为1-3μg·kg-1·min-1;B组:术中持续输注多巴胺复合去甲肾上腺素,初始输注速率分别为1-3μg·kg-1·min-1和0．03μg·kg-1·min-1,多巴胺输注速率不超过5μg·kg-1·min-1;术中两组均调节输注速率维持MAP 60-80 mm Hg。分别于切皮前即刻、切肝期1 h、无肝期1 h、新肝期1h和术毕测定血液动力学、组织代谢和肾功能指标。结果两组HR、 MAP均维持较平稳。无肝期两组CVP、MPAP、PAWP、CO、CI、DO2、VO2降低(P<0．05);SVR和SVRI升高(P<0．05),但均在正常范围内。术中PVR、PVRI、pH及SvO2均较平稳。乳酸浓度增高并持续到术毕。两组术中Cr和BUN均在正常范围,B组总尿量高于A组(P相似文献
