127例蛛网膜下腔出血案例的法医学研究

目的探讨蛛网膜下腔出血(SAH)对保险公司的直接请求权,从而缓解了患者在请求赔偿方面的特点及法医学鉴定要点。方法通过对华西医科大学法医鉴定中心1983-2001年尸检检出的127例各种原因所致的SAH案例进行回顾性分析。结果各类SAH案例,男性明显多于女性,男女性别比为3:1,高峰年龄为21~40岁。按SAH常见特征可分为外伤性、脑血管畸形、动脉瘤、脑血管粥样硬化、中毒、伴发于心脏疾患、其他等八类。其中,外伤性与脑血管畸形最为多见。外伤性SAH与脑血管畸形出血可见于任何年龄,多见于11~50岁,脑血管粥样硬化出血仅见于50岁以上者,动脉瘤破裂出血者并不多见,见于11~50岁。以SAH为死亡原因者,32例,占25%,多见于脑血管畸形与动脉瘤破裂,出血部位多见于脑底及小脑天幕以下。大多数SAH,出血部位多见于大脑表面,较为局限,出血量较少,非死亡的主要原因。结论多数SAH并非导致死亡的主要原因,SAH死亡者,其死亡性质多属自然死亡。     

上海地区非法行医致孕妇死亡案例回顾性研究

目的研究上海地区非法行医致孕妇死亡案例并分析其特点,探究其形成原因及预防机制。方法收集本研究所2001～2005年接受上海市公安机关委托非法行医致孕妇死亡案例11例,按照孕妇情况、死亡原因及非法行医者的诊疗措施等进行分类整理分析。结果非法行医致孕妇死亡的原因多为产后大出血、羊水栓塞,多伴软产道裂伤。孕妇多未进行正规产前检查,到缺乏必要医疗条件的个体非法行医者处或者家中分娩,非法行医者往往存在不正当应用催产素,强行分娩,未采取及时有效抢救措施。     

An Analysis of Human Skeletal Remains with Cerebral Palsy: Associated Skeletal Age Delay and Dental Pathologies*

Abstract: In 2002 the authors were asked to examine the skeletal remains of an individual with a known history of severe cerebral palsy (CP) who was 21–23 years old at death. Skeletal age estimates of 11–15 years and dental age estimates of c. 16 years are younger than the known age of the decedent. Skeletal analysis also identified dental pathologies such as chronic tooth grinding and substantial calculus deposits. Scarce literature exists on forensic human remains cases with CP, and this study contrasts the age discrepancy and other features of this case with typical clinical characteristics of CP. A review of the CP literature suggests that delayed skeletal maturation and dental pathologies such as those observed in this case are indicative of complications related to CP. This article may alert future investigators to some of the osteological signs of CP and the probability that age indicators may be misleading.     

Retropharyngeal Hematoma Secondary to Cervical Spine Surgery: Report of One Fatal Case

A 53‐year‐old woman suffering from radicular pain due to cervical herniation underwent a spinal surgery consisting of anterior cervical discectomy and fusion with an implantable titanium cage. Five hours after the procedure, the patient developed cervical swelling and dyspnea. An emergency surgery permitted evacuation of a deep cervical hematoma and intubation of the patient, who died some minutes later. The family of the deceased lodged a complaint with the public prosecutor because of unclear circumstances of death. After analysis of the medical records by two forensic pathologists, a medicolegal autopsy was ordered. Massive retropharyngeal and mediastinal hematomas were diagnosed. Pathological study confirmed acute cervical hemorrhage, but failed to detect the source of bleeding. The forensic pathologists concluded that death was due to mechanical asphyxia secondary to pharyngeal compression by the cervical hematoma. To the best of our knowledge, death secondary to retropharyngeal hematoma in this neurosurgical context is rarely encountered.     

Fat embolism syndrome associated with atraumatic compartment syndrome of the bilateral upper extremities: An unreported etiology

Fat embolism syndrome (FES) is a potentially life-threatening condition that develops when fat embolism leads to clinical symptoms and multisystem dysfunction. The classic triad of respiratory distress, neurologic symptoms, and petechial rash are non-specific, and the lack of specific laboratory tests makes the diagnosis of FES difficult. Although FES is most common after long bone fractures, multiple conditions some of which are atraumatic have been associated with the development of FES. We report a case of FES that occurred in the setting of a non-traumatic compartment syndrome of the upper extremities. The pathologic and clinical findings, pathophysiology, diagnostic challenges, and pathologic methods to properly diagnose FES are discussed with a review of the relevant literature. This case highlights the importance of the autopsy in making a diagnosis of FES in cases where death could otherwise be incorrectly attributed to multi-organ system failure, shock, or sepsis.     

Alcohol intoxication may exacerbate the effects of blunt cranial trauma through changes in brain free magnesium levels

Moderate to high levels of alcohol decrease brain intracellular free magnesium concentration, a factor known to be critical in brain injury. Phosphorus magnetic resonance spectroscopy was used to examine changes to brain free magnesium concentration after blunt cranial trauma in alcohol-intoxicated rats. Rats exposed acutely or chronically to alcohol sufficient to increase blood alcohol levels to between 150 and 350 mg/dL demonstrated a brain free magnesium level that was 20-50% less than in nonintoxicated animals (p < 0.01). After injury, brain free magnesium levels declined more rapidly and to a greater extent in alcohol-affected animals than in nonintoxicated control animals (p < 0.001). As both preinjury depletion of magnesium and degree of magnesium decline after brain injury have been associated with poor recovery, these findings suggest that moderate to severe alcohol intoxication may predispose the brain to a worse outcome by reducing brain free magnesium levels, both before and after injury.
