轿车与自行车碰撞事故仿真研究及骑车者致伤特点分析 总被引:2,自引:2,他引:0
目的研究计算机仿真技术重建自行车骑行状态下交通事故发生过程,并探讨此技术在分析真实事故中骑车者人体致伤方式、特点及损伤程度上的可行性。方法通过对事故人、车痕迹鉴定和模型建立,构建相关碰撞环境并利用高性能计算机及PC-Crash软件对事故进行再现研究。结果计算机仿真技术建立的人、车模型在模拟碰撞过程中,骑车者发生的运动过程、损伤分布及损伤动力学响应结果与法医学尸表检验人体损伤部位、程度基本吻合。结论利用计算机仿真技术重建自行车骑行状态下的事故碰撞过程、分析骑车者致伤方式及提供损伤部位动力学响应参数等,对于交通伤法医学鉴定及深化交通伤机制研究具有参考价值。 相似文献

Acute promyelocytic leukemia (APL) is a subtype of acute myelogenous leukemia frequently associated with clotting abnormalities and severe hemorrhagic diathesis. The disease is associated with a high incidence of early fatal hemorrhage. We report the sudden death of a 40-year-old male without significant medical history in which foul play had been initially suspected. A thorough postmortem investigation performed on the decedent lead to the diagnosis of APL. Cause of death was a cerebellar hematoma. Underlying APL should be considered in the differential diagnosis when unexplained bleeding is encountered in a decedent. This case emphasizes the value of routinely collecting bone marrow during an autopsy to enable accurate testing and diagnosis. 相似文献

Pituitary tumor apoplexy refers to a clinical syndrome precipitated by the expansion of a pituitary adenoma by hemorrhage or infarction. Individuals may present with myriad signs, including sudden onset of severe headache, visual changes, altered mental status, cranial nerve palsies, and hormonal dysfunction. This disorder constitutes a medical emergency and warrants an expedited evaluation, diagnosis, and treatment to prevent the potential sequelae of permanent visual loss, endocrine abnormalities, or death. We report a case of sudden death from undiagnosed pituitary tumor apoplexy. The decedent was evaluated by medical personnel on three occasions in the week prior to her death for severe headache, nausea, vomiting, and photophobia. Postmortem examination demonstrated a hemorrhagic infarction of a pituitary adenoma with necrosis and expansion out of the sella turcica. The recognition of and treatment for a patient with pituitary tumor apoplexy requires a rapid multidisciplinary effort. Failure of prompt diagnosis may be fatal and require a medico-legal death investigation for sudden and unexpected death. 相似文献

Abstract: In March 2009, a new strain of influenza A/H1N1 virus was identified in Mexico, responsible for a pandemic. Worldwide, more than 13,500 patients died, most often from acute respiratory distress syndrome. Because sudden death cases were rare, involving mostly young apparently healthy persons, influenza A/H1N1 (2009)‐related deaths may be misdiagnosed, which can raise medico‐legal issues. Case history: we report on an unexpected out‐of‐hospital death involving a young male with no past medical history and no vaccination. Fever was his only symptom. Laboratory tests: histology showed patchy necrotic foci with mononuclear inflammation in the lungs. The heart was histologically normal, but virological analyses using molecular biology on frozen myocardial samples showed high virus load. In conclusion, this case report shows that influenza A/H1N1 (2009) virus can be a cause of sudden cardiac death in the young and demonstrates the importance of quantitative virological analyses for the diagnosis of myocarditis. 相似文献

The case reported herein concerns the unexpected death of a 3-month-old female newborn who suddenly collapsed in her mother's arms and was dead on arrival at the hospital. The clinical histories of the baby and her parents were negative for symptoms or signs of illness, even those of cardiovascular origin. Furthermore, no clinical appearance of a pathologic status was noted by pediatricians after the birth until the last emergency recovery. The autopsy excluded external and internal signs of violence but revealed a large primary cardiac tumor arising from the free wall of the left ventricle, which had totally invaded the heart causing mitral valve deformation. Histological examination showed a low-grade sarcoma that completely infiltrated the myocardial tissue. The pathogenesis of this sudden infant death was postulated as being owing to a fatal ventricular fibrillation combined with a tumor-related restrictive cardiomyopathy obstructing left ventricular filling. 相似文献

Prolapse rectum (PR) or protrusion of the rectum beyond the anus occurs frequently in populations at both extremes of age. In the pediatric population, in developed countries, the commonest cause for PR is thought to be cystic fibrosis (CF). Treatment options for CF include conservative management, surgical resection and fixation, suturing, and injection sclerotherapy (IS). The last is considered an attractive treatment option because it is minimally invasive. In this case report, the authors present the details about a 2-year-old female child, with PR and CF, who died after IS, using phenol as the sclerotherapeutic agent. Autopsy findings and toxicology tests performed to establish phenol toxicity are documented. The available literature is reviewed. This case report underscores the risks of using phenol for IS and emphasizes the point that the procedure is not innocuous and an adverse outcome including fatality is a possibility. 相似文献

正IN 2012,the short film A Bed Affair became an Internet sensation in China.Through the eyes of a thief surprised by the sudden return of the flat owners during his foray,director Zhang Yuan allows the audience a 36-minute,fly-on-thewall look into an ordinary Chinese bedroom.However,what the viewers are confronted with are not intense love scenes,but a fierce quarrel that flares up between Zhang Cheng(played by Shen Teng)and his wife Li Xiaoyun(Li Xinyun)over a missing condom. 相似文献

不同的归责原则体现不同的责任分配思想和责任承担基础,因此其责任主体的认定标准也不相同。《道路交通安全法》第76条没有采纳单一的归责原则,而是区分不同的责任范围和交通事故类型分别适用不同的归责原则。"运行支配和运行利益"是危险责任原则下保有者或者运行供用者的判断标准,因此将其作为我国机动车交通事故责任主体的判断标准必然与《道路交通安全法》第76条第(一)项所确立的过错责任相冲突。我国未来制定的民法典应当在厘清归责原则与责任主体之间关系的基础上,正确定位机动车交通事故责任的归责原则,并规定与之相适应的责任主体。 相似文献
