摘要:
Medical examiners and coroners commonly determine cause and manner of death without an autopsy examination. Some death certificates generated in this way may not state the correct cause and manner of death. From the case files of the Department of Forensic Medicine in Sydney, Australia, the authors retrospectively reviewed investigative information of all cases in a 6-month period that were initially considered natural deaths (429). The authors, blinded to autopsy results, accepted 261 cases as appropriate for certification without autopsy and assigned a cause of death to each. Per standard local practice, all cases had been autopsied. The actual causes of death as determined by autopsy were then revealed and compared with the presumed causes of death. Most presumed and actual causes of death were cardiovascular (94% and 80%, respectively). The majority of presumed causes of death were listed as ASCVD as the cases lacked features of a more specific cardiovascular process. A large majority of cases had a presumed cause of death of ischemic heart disease based on individual case details. The actual causes of death demonstrated a large breadth of cardiovascular and noncardiovascular disease processes, even though ischemic heart disease accounted for 62% of deaths. The presumed cause of death was completely wrong in 28% of cases. A nonnatural manner of death was present in 3% of cases. This study demonstrates that experienced forensic pathologists may generate erroneous death certificates for cases that are not autopsied.

摘要:
The investigation of the neck structures drawn from 145 cases of asphyxia involving pressure on the neck, for which microscopic examination was required at the Pathology Laboratory of the “Hotel Dieu” Hospital from Lyon, France, during January 1, 1999, to May 1, 2001, has pointed out in 3 cases, besides the classic signs already known, a particular lesion unmentioned yet in the literature, namely, a pericarotid bone splinter, placed in the proximity of the common carotid artery bifurcation. The bone splinters had dimensions between 0.25 and 0.7 mm and a certain antemortem character, surrounded by hemorrhagic areas and by fibrin. The 3 cases deal with adult males who had died through complete hanging, with the knot placed lateral, the hanging mark having the maximum depth in the laterocervical region, correspondent with our finding. Given the location of the bone splinter, we believe that this was produced by the tearing out from the transverse apophysis of the fourth cervical vertebra, as a consequence of the sudden traction during hanging. This sign appeared neither at other types of hanging nor at strangulation by hand or by ligature.

摘要:
The field of forensic anthropology involves the building of an antemortem profile of an individual from skeletal remains. This includes sex and race determination and age and stature estimation. Since most bones that are conventionally used for sex determination are often recovered either in a fragmented or incomplete state, it has become necessary to use denser bones that are often recovered intact, eg, the patella, calcaneus, and talus. Thus the aim of this study is to assess the sex-determining ability of each of the measurements of the talus and derive discriminant function equations for sex determination in the South African white population. Sixty male and 60 female tali of South African whites obtained from the Raymond A. Dart Collection of Human Skeletons were used. Nine measurements were taken on each talus. Descriptive statistics and discriminant function analysis were performed on the acquired data. The basic statistics showed that all measurements were sexually dimorphic. Univariate, stepwise, and direct discriminant function equations were generated for use in sex determination. The level of average accuracy of sex classification was 80% to 82% for the univariate method, 85% to 88% for the stepwise method, and 81% to 86% for the direct method. It is concluded that the talus of South African whites is useful for sex determination.

摘要:
Pulmonary thromboembolism is an often fatal complication of venous thrombosis. Any component or combination of the components composing Virchow’s triad (venostasis, hypercoagulability, and endothelial damage) increases the propensity for a thrombophilic state. Hypercoagulable states may be inherited or acquired. While the etiology in many cases may be evident either on physical examination or on evaluation of the decedent’s medical history, this is often not the case. We conducted a retrospective study of cases presenting to the Jefferson County Coroner/Medical Examiner’s Office in Birmingham, Alabama, who were given a diagnosis of pulmonary embolism. A search of cases within the past 23 years yielded 81 cases. An underlying cause was determined in 70 cases (86%). The remaining 11 (14%) cases had no identifiable cause. We believe that a number of these cases may represent an underlying thrombophilic disorder. Since these disorders may be of an inherited or acquired nature, the determination of an etiology may be relevant to the decedent’s family. Postmortem blood analyses may in selected cases be useful and appropriate for the detection of some of these disorders. However, such analyses are not practical in all cases, with each case having to be evaluated on its own merits.

摘要:
During the interaction between a criminal suspect and a law enforcement officer, the risk of death to the suspect, police, or civilians is increased. Unfortunately, very little information is available on the death risks arising from this interaction. This study provides an assessment of the risk of death to law enforcement officers, suspects, and bystanders by separating the interactions into the following 4 phases: (1) events prior to and during arrest; (2) police pursuits or chases; (3) transport of the suspects; and (4) during incarceration. A 5-year (1994–1998) retrospective coroner-based study of all deaths that occurred during these 4 phases was conducted in Allegheny County, Pennsylvania. A total of 77 cases were identified; 14 deaths (18.1%) occurred prior to or during arrest, 10 (12.9%) during police chases, 2 (2.6%) occurred while the actors were being transported, and 51 (66.2%) during incarceration. The majority of cases (98.7%) were males, blacks (63.6%), and single (50.6%). The respective risks of death by phase were prearrest/arrest, 6.5 per 100,000 arrests; transport, 0.93 deaths per 100,000 arrests; and incarceration, 268 deaths per 100,000 inmates. Study showed the following: (1) risk of death to offenders was greatest during police pursuits; (2) the risks during arrests are not insignificant and involved an officer being threatened with a weapon in one-third of the events; and (3) deaths among inmates were primarily due to natural causes.

摘要:
In this study, it was aimed to investigate the relationship between skull fractures and intracranial lesions following head injury. For this purpose, 500 cases, which were referred to the Third Committee of Council of Forensic Medicine in Istanbul due to traffic accidents by the courts of laws between 1998 and 2000, were examined retrospectively. They were categorized in 3 groups based on findings of their cranium x-rays and brain tomographies. 1- The cases who have fractures in skull bones with brain lesions 2- The cases who have fractures in skull bones with no brain lesions 3- The cases who have brain lesions with no skull fractures. They were examined in detail according to age, sex, localization of skull fractures and brain lesions, and if surgery was applied or not.Of the cases, 152 (30.4%) had only linear fractures, 69 (13.8%) had depressed fractures, 92 (18.4%) had linear fractures plus intracranial lesions, 49 (9.8%) had depressed fractures plus intracranial lesions and 138 (27.6%) had only intracranial lesions. The rate of intracranial lesion among the cases with the skull fracture was 38.9% (141/362), while the rate of skull fracture among the cases with the intracranial lesion was 50.3% (141/279) (P< 0.001). Male to female ratios were 2.4/1 for linear fractures, 5.2/1 for depressed fractures, and 3.5/1 for intracranial lesions. Linear fractures were more frequent among females whereas depressed fractures were often among males (&khgr;2: 9.68,df: 4, p: 0.046). The mean age was 26.3. The rate of depressed fractures was higher the age groups of 0–30 years. (&khgr;2: 16.28,df: 4, p: 0.003). Depressed fractures in the regions of frontal and parietal and, linear fracture in the regions of temporal and occipital were found at higher rates (P< 0.001).In conclusion, we reviewed skull fractures and/or intracranial lesions due to traffic accidents, and found depressed fractures to be more common among males whereas linear fractures to be more common among females and young males. In the male, the skull architecture is thicker and stronger than females and young males. We can state that presence of skull fractures lowers the incidence of intracranial lesions by lowering the intracranial pressure.

摘要:
Drug use in the workplace is a problem, both in terms of public health and expense. Workplace drug testing programs serve as deterrents to drug use. Model programs, such as that of the Department of Transportation, use urine screening and are federally regulated or follow federal standards. An essential participant in this process is the medical review officer (MRO), a licensed physician who interprets the laboratory results generated from a workplace drug testing program. As a result of their training and experience with toxicology, collection of evidence, testimony, and recognition of the physical signs of drug abuse, medical examiners and forensic pathologists are well suited to serve as MROs. Recent regulations require the completion of training courses and MRO certification as prerequisites for participation in federal drug testing programs. Several courses are available to train physicians to participate as MROs.

摘要:
Treatment for individuals suffering from migraines and pain due to an inflammation or impingement of a nerve range from noninvasive methods such as massage, physical therapy, and medications to invasive methods such as epidural steroid injections and surgery. Each method of treatment has an associated level of risk. While minor to moderate complications from such procedures do occur, deaths are very rare. We report the first cited case of a death associated with the pain management procedure called nerve root block, also referred to as a transforaminal epidural steroid injection. We present the medical history and autopsy findings of a 44-year-old white female who died of massive cerebral edema secondary to the dissection of the left vertebral artery and subsequent thrombosis due to the perforation of that artery by a 25-gauge spinal needle during a C-7 nerve root block.

摘要:
Reported is a case of an assault causing extensive blunt force injuries in which the clinical, radiologic, and postmortem findings were all consistent with death resulting from brain damage arising from the assault. The assailant was charged with murder. Subsequent full neuropathologic (including histologic) examination revealed the unsuspected finding of a widespread meningoencephalitis but no evidence of significant traumatic brain damage. The contributions of the infective process and of the trauma to death were felt to be unclear and a guilty plea to attempted murder was accepted. This case highlights the importance of a full neuropathologic examination, including histology, in cases of trauma to the head, even when the cause of death may initially appear obvious.

摘要:
Suffocation by inhaled gases has been reported involving a variety of gases. We report a case of suicidal asphyxiation by forced replacement of oxygen with helium by using a complex homemade mask. In this case, a young woman researched suicide on the Internet and found an advocated method of suicide using helium. To our knowledge, there is only 1 previously reported case of suicidal asphyxia by using helium.
