简介：AbstractPediatric and adult spinal cord injuries (SCI) are distinct entities. Children and adolescents with SCI must suffer from lifelong disabilities, which is a heavy burden on patients, their families and the society. There are differences in Chinese and foreign literature reports on the incidence, injury mechanism and prognosis of SCI in children and adolescents. In addition to traumatic injuries such as car accidents and falls, the proportion of sports injuries is increasing. The most common sports injury is the backbend during dance practice. Compared with adults, children and adolescents are considered to have a greater potential for neurological improvement. The pathogenesis and treatment of pediatric SCI remains unclear. The mainstream view is that the mechanism of nerve damage in pediatric SCI include flexion, hyperextension, longitudinal distraction and ischemia. We also discuss the advantages and disadvantages of drugs such as methylprednisolone in the treatment of pediatric SCI and the indications and timing of surgery. In addition, the complications of pediatric SCI are also worthy of attention. New imaging techniques such as diffusion tensor imaging and diffusion tensor tractography may be used for diagnosis and assessment of prognosis. This article reviews the epidemiology, pathogenesis, imaging, clinical characteristics, treatment and complications of SCI in children and adolescents. Although current treatment cannot completely restore neurological function, patient quality of life can be enhanced. Continued developments and advances in the research of SCI may eventually provide a cure for children and adolescents with this kind of injury.

简介：AbstractSpondyloptosis in the clinic is rarely reported. We herein present a 47-year-old female, who suffered from a crush injury directly by a heavy cylindrical object from the lateral side. She was diagnosed to have traumatic L3 spondyloptosis with multiple traumas. Staged surgical procedures were conducted and a three-year follow-up was obtained. Eventually, normal spinal alignment was restored, and neurological deficits were gradually improved. At three years follow-up, the motor strength scores and function of the sphincters were incompletely improved. Previously published reports on traumatic lumbar spondyloptosis were reviewed and several critical points for management of this severe type of spinal injury were proposed. First, thoracolumbar and lumbosacral junction were mostly predilection sites. Second, numerous patients involving traumatic lumbar spondyloptosis were achieved to American Spinal Injury Association grade A. Third, lumbar spondyloptosis was commonly coupling with cauda equina injury. Finally, the outcomes were still with poorly prognosis and recovery of patients was correlation to spondyloptosis severity. Based on this case report and literatures review, we highlighted that the spinal alignment restoration relying on staged operations and following rehabilitation hereof are both important once facing with multiple traumas. Furthermore, we suggested to perform routine CT angiography during lumbar spondyloptosis to justify whether there are large vessel compression or injury.

简介：摘要：目的：探讨经肛门指诊下治疗女童阴道球形异物的取出效果。方法：回顾性分析于2010年9月至2018年10月期间在我院泌尿外科门诊就诊9例阴道球形异物女童，经肛门指诊辅助下取出异物，评估该治疗手段的治疗效果及安全性。结果：9例患儿有3例治疗前行镇静，其余6例在清醒状态下尝试肛门指诊取出异物，9例患儿均顺利取出异物且无阴道出血、裂口等情况。结论：经肛门指诊下治疗女童阴道球形异物是一种有效、安全的非创伤性治疗方案。

简介：摘要：颈椎病是常见病、多发病，严重影响人们的日常生活及工作。而针灸具有舒筋通络、活血止痛之功效，可有效改善颈部血液循环，缓解局部疼痛、僵硬、麻木等症状，从而改善颈椎部分生理功能。临床中发现传统针灸疗程较长，而将王氏针灸和脐针理论相结合选取相应穴位治疗颈型颈椎病，可以明显缩短疗程，甚至取到立竿见影的效果。故本文报告3例临床中采用王氏针灸和脐针理论相结合治疗颈型颈椎病病例，以供临床针灸学者及医务人员参考。
