胸部损伤死因鉴定审查在诉讼中的应用

人身伤害案件被害人的死因鉴定,轻则涉及被告人的量刑,重则事关案件的定性。而司法实践中,经常遇到一些刑事被害人的死因鉴定意见是建立在推断的基础之上,且其推断不具有排他性,经不起推敲,往往直接影响到案件的定性与处理。针对这一问题,结合司法案例进行分析,以期提升死因鉴定的证明力和法医学鉴定意见的公信力。     

A Forensic and Medical Evaluation of Dog Bites in a Province of Western Turkey

The aim was to evaluate the demographic data of dog‐bite cases organized from criminal and forensic reports. This study evaluated 328 cases admitted to the Director of Forensic Medicine, Eskisehir, as a result of dog bites between January 1, 2006 and December 31, 2010. It was found that those in the age‐group of 0–18 were most frequently exposed to dog bites (48.5%). Injuries to the lower extremity, upper extremity, and chest/abdomen/back were more frequent in men (72.6%, 76.4%, and 66.1%, respectively), while injuries to the head/neck/face were more frequent in women (52.3%) (p < 0.01). While most of those wounded in the upper extremity, the head/neck/face, and the chest/abdomen/back were in the child age‐group, most of those wounded in the lower extremity were in the adult age‐group (p < 0.001). Teaching children, in particular, how to behave around dogs would be useful in reducing the incidence of bite.     

Blast Injury and the Human Skeleton: An Important Emerging Aspect of Conflict‐Related Trauma

Recent decades have seen an accelerating trend in warfare whereby a growing proportion of conflict‐related deaths have been caused by explosions. Analysis of blast injury features little in anthropological literature. We present a review of clinical literature that includes prevalence of injury to anatomical regions and potential indicators of blast injury which can be used by forensic anthropologists. This includes high prevalence of extremity (22.8–91.2%) and facial (19.6–40%) injury in combat contexts, lower limb fractures (19–74.3%) in suicide bombing, traumatic amputation (3–43%) and diffuse fracture patterns in terrorist bombings. Potential indicators of blast trauma include blowout fractures in sinus cavities from blast overpressure, transverse mandibular fractures, and visceral surface rib fractures. Ability to recognize blast trauma and distinguish it in the skeleton is of importance in investigations and judicial proceedings relating to war crimes, terrorism, and human rights violations and likely to become increasingly crucial to forensic anthropology knowledge.     

A New Tool for Coding and Interpreting Injuries in Fatal Airplane Crashes: The Crash Injury Pattern Assessment Tool Application to the Air France Flight AF447 Disaster (Rio de Janeiro–Paris), 1st of June 2009

For investigation of air disasters, crash reconstruction is obtained using data from flight recorders, physical evidence from the site, and injuries patterns of the victims. This article describes a new software, Crash Injury Pattern Assessment Tool (CIPAT), to code and analyze injuries. The coding system was derived from the Abbreviated Injury Score (AIS). Scores were created corresponding to the amount of energy required causing the trauma (ER), and the software was developed to compute summary variables related to the position (assigned seat) of victims. A dataset was built from the postmortem examination of 154/228 victims of the Air France disaster (June 2009), recovered from the Atlantic Ocean after a complex and difficult task at a depth of 12790 ft. The use of CIPAT allowed to precise cause and circumstances of deaths and confirmed major dynamics parameters of the crash event established by the French Civil Aviation Safety Investigation Authority.     

Total Situs Inversus Found Coincidentally Following a Firearm Injury

Situs inversus totalis is very rare and usually diagnosed coincidentally as it does not affect the patient's life. Being unaware of the patient's condition can lead to undesirable results from the surgeon and patient's point of view when an emergency and forensic surgical intervention is required. We present a case who was operated on urgently for a firearm injury after receiving a preoperative diagnosis of situs inversus totalis. In conclusion, situs inversus totalis can cause difficulties for surgeons in case of emergency surgery and is usually diagnosed coincidentally. There are a few cases of situs inversus with lung cancer in the literature but this is the first time a case with a firearm injury has been reported.     

Use of Cardiac Injury Markers in the Postmortem Diagnosis of Sudden Cardiac Death

In the daily practice of forensic pathology, sudden cardiac death (SCD) is a diagnostic challenge. Our aim was to determine the usefulness of blood biomarkers [creatine kinase CK‐MB, myoglobin, troponins I and T (cTn‐I and T), and lactate dehydrogenase] measured by immunoassay technique, in the postmortem diagnosis of SCD. Two groups were compared, 20 corpses with SCD and 8 controls. Statistical significance was determined by variance analysis procedures, with a post hoc Tukey multiple range test for comparison of means (p < 0.05). SCD cases showed significantly higher levels (p < 0.05) of cTn‐T and cTn‐I compared to the control group. Although only cases within the first 8 h of postmortem interval were included, and the control group consisted mainly of violent death cases, our results suggest that blood troponin levels may be useful to support a diagnosis of SCD.     

Importance of electromyography and the electrophysiological severity scale in forensic reports

Forensic reports on traumatic peripheral nerve injuries include dysfunction degrees of extremities, which are arranged according to the Turkish Penalty Code. The aim of this study is to discuss the role and importance of electromyography while preparing forensic reports in the cases of traumatic peripheral nerve injuries and the usefulness of scoring systems. A modified global scale, recommended by Mondelli et al., was used to assess the electrophysiological impairment of each peripheral nerve. Forensic reports of 106 patients, reported between 2002 and 2004, were evaluated. Thirty-four percent of the cases were reported as "total loss of function," 41.5% were reported as "functional disability," and there were no dysfunctions in the other cases in forensic reports that were prepared based on Council of Social Insurance Regulations of Health Processes and Guide prepared by the Council of Forensic Medicine and profession associations of forensic medicine. When we rearranged these forensic reports based on the electrophysiological severity scale (ESS), it was clearly found that all of the score 2 cases and 86.7% of the score 3 cases corresponded to "functional disability" and 91.4% of the score 4 cases correspond to "total loss of function." We found a significant correlation between the ESS and functional evaluation in peripheral nerve injury cases. Evaluation of functional disabilities in peripheral nerve injuries with the ESS represents a standardized and objective method used for forensic reports.     

交通事故中摩托车司乘人员致伤方式分析

通过对3例摩托车交通事故中司乘人员的损伤特征及车辆痕迹的检验结果比对,分析事故过程中摩托车司乘人员的运动过程及致伤方式,发现因其位置、姿势和应激状态不同,摩托车驾驶位乘员与后座乘员在碰撞、运动过程中损伤形成不同,其人体成伤机制、部位及程度与车辆相关部位的损害痕迹可以相互佐证,对于推断摩托车司乘人员的行为方式(谁是摩托车驾驶员)具有重要价值。进一步总结此类事故鉴定的共同特点,可为事故责任认定提供参考。
