Fabrice Dedouit M.D. Ph.D. Stéphane Grill M.D. Céline Guilbeau‐Frugier M.D. Ph.D. Frédéric Savall M.D. Daniel Rougé M.D. Ph.D. Norbert Telmon M.D. Ph.D. 《Journal of forensic sciences》2014,59(5):1427-1431
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. 相似文献

Self-inflicted burns are rare in France, but they lead to major, often life-threatening complications. The authors reviewed medical data for patients hospitalized in a burn center from January 2004 to December 2008. Thirty-eight cases of self-inflicted burns were compared with 220 accidental burns. Women were predominantly affected (57.9%, n = 22). A psychiatric history (71%, n = 27) was more frequent in this population. The mean age of the victims was 38 years. The leading method of suicide was flame (94%, n = 36) associated with gasoline used as an accelerant (77.7%, n = 28). Mean total burn surface area (41.5%) and mortality (36.9%) were higher in the self-inflicted burn population. By recognizing epidemiological characteristics and patients at risk, we can better classify lesions related to self-immolation. It is important for the forensic physician to consult survival details to correlate these data with the results of autopsy. 相似文献

Since it is established that human chorionic gonadotropin (hCG) affects testosterone production and release in the human body, the use of this hormone as a performance enhancing drug has been prohibited by the World Anti-Doping Agency. Nowadays, the only validated biomarker of a hCG doping is its direct quantification in urine. However, this specific parameter is subjected to large inter-individual variability and its determination is directly dependent on the reliability of hCG immunoassays used. In order to counteract these weaknesses, new biomarkers need to be evidenced. To address this issue, a pilot clinical study was performed on 10 volunteers submitted to 3 subsequent hCG injections. Blood and urine samples were collected during two weeks in order to follow the physiological effects on related compounds such as the steroid profile or hormones involved in the hypothalamo-pituitary axis. The hCG pharmacokinetic observed in all subjects was, as expected, prone to important inter-individual variations. Using ROC plots, level of testosterone and testosterone on luteinizing hormone ratio in both blood and urine were found to be the most relevant biomarker of a hCG abuse, regardless of inter-individual variations. In conclusion, this study showed the crucial importance of reliable quantification methods to assess low differences in hormonal patterns. In regard to these results and to anti-doping requirements and constraints, blood together with urine matrix should be included in the anti-doping testing program. Together with a longitudinal follow-up approach it could constitute a new strategy to detect a hCG abuse, applicable to further forms of steroid or other forbidden drug manipulation. 相似文献
