An attempt to objectify the condition of cervical spine distortion injury in traffic accident victims for court purposes

Introduction

According to morphological criteria, cervical spine injuries include, among others, contusion, distortion, luxation and fracture. Distortion of the intervertebral articulations occurs when the force of movement exceeds the physiological range, and the articular/joint capsule, cartilage and ligaments are damaged. While within the articulation a haematoma is formed, which produces clinical manifestations such as localised idiopathic pain, tenderness to palpation and analgesic limitation on both the passive and active joint mobility (i.e., a syndrome of subjective painfulness), as reported by the patient, the diagnostic imaging techniques (i.e., regular radiograph pictures) typically applied in such cases do not show any post-traumatic changes. Distortion of the cervical spine, resulting in a post-traumatic feeling of pain, usually occurs indirectly as a result of transmission of the force of injury onto the spine, as in the case of a traffic accident. Frequently, in cases of abuse, arriving at a hasty clinical diagnosis of post-traumatic cervical spine distortion apparently presents a serious problem in giving medical opinions for court purposes; thus encouraging the authors to attempt objectifying the condition of cervical spine distortion.

Methods

In a retrospective investigation, the authors analysed the medical opinions given by the Department of Forensic Medicine, Medical University of Silesia, for court purposes.

Results

Among nearly 5500 opinions in the past 5-year period, we analysed 167 cases related to cervical spine injury.

Conclusions

An attempt is made to either substantiate or negate the clinical diagnosis issued for court purposes by assessing the following: the findings of the physical examination of the person involved, the condition of the person involved in the accident from the period prior to accident (radiograph findings confirming the level of the already existing degenerative changes; age and sex of the person involved; positive or negative history of injuries sustained prior to accident), the course of treatment after the accident (character of symptoms reported and their evolution with time; co-existence of other bodily injuries; outpatient treatment instituted, including the application of Schantze collar, rehabilitation) and also the circumstances in which the accident occurred.     

Megaesophagus and Possible Mechanisms of Sudden Death

Abstract:  Achalasia is a neurodegenerative condition characterized by esophageal dysmotility and megaesophagus. Two cases are reported that demonstrate unexpected deaths associated with previously unsuspected achalasia. Case 1: A 66-year-old woman was found dead at her home. At autopsy significant stenosing coronary artery atherosclerosis was found with cardiac failure. In addition, a striking finding was narrowing of the distal esophagus with marked proximal dilatation. The esophagus was completely filled with a large amount of soft masticated food and was bulging anteriorly, compressing the left atrium. Death was attributed to ischemic heart disease complicated by previously unsuspected achalasia. Case 2: An 84-year-old man collapsed and suffered a respiratory arrest while eating. Internal examination revealed narrowing of the cardioesophageal junction with marked proximal dilatation of the esophagus that contained approximately 50 mL of soft semi-fluid masticated yellow food paste. Fragments of yellow masticated food remnants were present in upper and lower airways but not within the stomach. There was a history of dementia with symmetrical cerebral ventricular dilatation found at autopsy. Death was attributed to food asphyxia complicating previously unsuspected achalasia with dementia. Megaesophagus may, therefore, be a significant finding at autopsy that may either be a primary cause of unexpected death or else may exacerbate or compound the effects of pre-existing underlying disease.     

An Analysis of Possible Mechanisms of Unexpected Death Occurring in Hydatid Disease (Echinococcosis)

Abstract:  Most cases of hydatid disease in human populations are due to Echinococcus granulosus. The hydatid life cycle involves passage between definitive hosts such as dogs and intermediate hosts such as sheep. Humans become accidental intermediate hosts following ingestion of food or water contaminated with eggs or by contact with infected dogs. Although hydatid disease may remain asymptomatic, occasional cases of sudden and unexpected death present to autopsy. Causes of rapid clinical decline involve a wide range of mechanisms including anaphylaxis (with or without cyst rupture), cardiac outflow obstruction or conduction tract disturbance, pulmonary and cerebral embolism, pericarditis, cardiac tamponade, myocardial ischemia, pulmonary hypertension, peritonitis, hollow organ perforation, intracerebral mass effect, obstructive hydrocephalus, seizures, cerebral ischemia/infarction, and pregnancy complications. The autopsy assessment of cases therefore requires careful examination of all organ systems for characteristic cystic lesions, as multiorgan involvement is common, with integration of findings so that possible mechanisms of death can be determined. Measurement of serum tryptase and specific IgE levels should be undertaken for possible anaphylaxis.     

Sickle Cell Trait Mimicking Multiple Inflicted Injuries in a 5-Year-Old Boy

Abstract:  Sickle cell disease (SCD) and sickle cell trait (SCT) can be associated with sudden unexpected death in the pediatric population, usually due to pulmonary complications occurring within the acute chest syndrome (ACS). Musculoskeletal complications can occur and are classically limited to bone infarcts. The occurrence of bone pathology centered upon the epiphyseal growth plate in SCD/SCT is extremely rare, and multiple such injuries in a single patient have not been previously reported. Herein, we describe a case of sudden unexpected death in a 5-year-old child with undiagnosed SCT due to the ACS, with widespread epiphyseal and periosteal bone lesions mimicking multiple inflicted injuries at autopsy. This case highlights the importance of clinicopathological correlation and is the first to describe SCT pathology as a mimic of nonaccidental injury.     

Vitreous Fluid and/or Urine Glucose Concentrations in 1335 Civil Aviation Accident Pilot Fatalities*

Abstract: During aviation accident investigations, vitreous fluid and urine samples from pilot fatalities are analyzed for glucose and blood for hemoglobin A_1c (HbA_1c) to monitor diabetic pilots and to discover other pilots with undiagnosed/unreported diabetes. The prevalence of elevated glucose concentrations in fatally injured pilots was evaluated by searching the Civil Aerospace Medical Institute’s Toxicology Database for the period 1998–2005. Out of 1335 pilots involving 363 vitreous fluid, 365 urine, and 607 vitreous fluid and urine analyses, 43 pilots had elevated glucose in vitreous fluid (>125 mg/dL) and/or in urine (>100 mg/dL). Of the 20 pilots whose blood samples were analyzed, nine had >6% HbA_1c—four were known diabetics, and five were unknown diabetics. Urinary glucose levels were elevated in all 13 known hyperglycemic pilots. A considerable number of pilots (30 of 43) had elevated glucose and HbA_1c (5 of 20), suggesting undiagnosed/unreported diabetic conditions.     

病毒性心肌炎猝死心肌MCP-1表达及其法医学意义

目的探讨单核细胞趋化蛋白1（monocyte chemoattractant protein-1,MCP-1）在病毒性心肌炎（viral myocarditis,VMC）所致猝死者心肌组织中的表达及其意义。方法运用改良的免疫组织化学方法,观察VMC猝死组和对照组心肌组织中MCP-1的表达情况,应用统计学处理,比较两组间的表达差异。结果20例VMC猝死组中有17例MCP-1染色阳性;而20例非VMC猝死对照组仅4例局部散在MCP-1弱阳性表达,其余均阴性。VMC组MCP-1阳性表达率明显高于对照组（P〈0.01）。结论MCP-1的免疫组织化学检测可作为法医病理学诊断VMC所致猝死较为客观的病理形态学指标之一。     

医疗事故技术鉴定专家出庭质证问题阐释

医疗事故技术鉴定专家出庭接受质证是法院审查、认定鉴定结论以及克服医疗事故技术鉴定自身中立性不足和程序不完善等问题的必然要求。鉴定专家出庭接受质证程序要体现交叉询问原则,同时,要引入专家辅助人、专家陪审员制度以构建均衡合理的质证主体结构。质证的内容应该围绕鉴定专家资格,鉴定结论的相关性、科学性、事实材料充分性、证明过程符合逻辑性等来展开。     

Accidental Ligature Strangulation by an Ironing Machine: An Unusual Case*

Abstract: In this paper, we present a case of a 53‐year‐old woman who had her headscarf catch on the cylinder ironing machine in the laundry of the hospital where she worked. The hospital workers found the woman dead with her head stuck to the ironing machine. After the death scene investigation and autopsy were completed, it was determined that the death occurred as a result of accidental ligature strangulation. Accidental ligature strangulation in which an article of clothing is caught in such an electrical machine and strangles the wearer is very rare. This case highlights the fact that these kinds of machines can be hazardous to work around and that increased safety measures should be taken to insure worker safety; additionally, the people who use these machines should be educated on the potential hazards.
