摘要:
Suicide by self-inflicted blunt force injury is rare. The authors report a case of a 48-year-old man who initially appeared to have died of a homicidal beating. The pertinent autopsy findings consisted of blunt force closed head injury combined with numerous cutaneous abrasions and contusions of the entire body. Further inquires confirmed a medical history of paranoid schizophrenia and a previous attempt at suicide. This case represents an extreme example of severe blunt trauma sustained during fatal self-mutilation and masquerading as a homicide. It also underscores the importance of correlating a thorough background investigation with autopsy findings in determining the appropriate manner of death.

摘要:
It has been proposed that the presence of siderophages in the lungs of infants who die unexpectedly should be considered a marker of a previous hypoxic event, which may preclude a diagnosis of sudden infant death syndrome. The authors retrospectively reviewed all infant deaths (<1 year old) going to autopsy at the Denver Office of the Medical Examiner from January 1999 to January 2001. Lung sections were stained with Prussian blue, and siderophages were counted in 20 high-power fields per lobe sampled. Cell counts were performed by two independent pathologists who were blinded to history and cause of death, with good reproducibility. Iron stain results were then categorized by average number of siderophages per 20 high-power field (category 1 = <5, category 2 = 5–100, category 3A = 100–500, category 3B = >100 in a single lobe, category 4 = >500). The results were subsequently correlated to case history, autopsy findings, and cause/manner of death. Forty-three cases were reviewed. The causes of death included sudden infant death syndrome (16), asphyxia (5), undetermined (6), and other (16). Those deaths were categorized by the above criteria as follows: category 1 (32), category 2 (6), category 3 (4), and category 4 (1). All sudden infant death syndrome deaths were in category 1. Categories 1 and 2 also included deaths in which hypoxia might have been present before death because of such factors as pneumonia and congenital heart disease. Categories 3 and 4 included a known homicidal asphyxia in which repeated episodes of intentional smothering were documented, 2 probable asphyxias, 1 nonaccidental trauma, and 1 undetermined. All 5 cases had questionable circumstances surrounding the death of the infant. Pulmonary siderophages were described in only 1 of the 43 autopsy reports. It was concluded that pulmonary siderophages can be markedly increased in cases of repeated asphyxia. Siderophages may also be increased in cases where hypoxia may have been present for another reason, but not to the same degree. Siderophages are not increased in sudden infant death syndrome. Because iron-laden macrophages often are not recognized on routine examination with hematoxylin and eosin staining, iron stains may be helpful in the evaluation of infant deaths. If siderophages are present in increased amounts without an obvious explanation, further investigation is warranted.

摘要:
Exercise-induced collapse and sudden death are unusual in childhood. For this reason, a study was undertaken of a series of 12 cases of sudden death in childhood occurring during physical exertion associated with sporting activities. The age range was 7 to 16 years (mean 12.3 years, M:F ratio 5:1). Deaths resulted from trauma associated with the sporting activity, from an idiosyncratic response to exertion, or from exacerbation of a known underlying disease. Trauma was directly fatal (n = 4: vascular trauma in 1, head injury in 2, drowning in 1), exacerbated an underlying medical condition (n = 1: hypertrophic obstructive cardiomyopathy), or followed collapse from underlying organic disease (n = 1: drowning in epilepsy). Deaths after exertion occurred when there was an unexpected response to underlying occult disease (n = 4: aortic stenosis in 1, cerebral arteriovenous malformation in 1, hypertrophic obstructive cardiomyopathy in 1, coronary atherosclerosis in 1) or to preexisting known disease (n = 2: surgically corrected transposition of the great vessels in 1, asthma in 1). The fatal episodes often resulted from a complex interplay of a variety of factors, including physical exertion, possible trauma, and underlying organic disease. Testing of other family members may be indicated in cases where a rare, possibly familial, disease is found. Evaluation of cases required descriptions of activities before death, information from the medical history of the deceased, and detailed findings from the autopsy.

摘要:
Epidermoid cysts of the brain are rare tumor-like lesions, most often of maldevelopmental origin. They are benign in nature, causing symptoms depending on their localization. Surgical resection leads to excellent results. A case is reported of a 68-year-old-man who died suddenly and unexpectedly. Postmortem examination revealed signs of central dysregulation and a bifrontal epidermoid cyst. To the authors’ knowledge, death resulting from epidermoid cyst of the brain has not been reported so far.

摘要:
The diagnosis of drowning relies primarily on critical examination of the subject’s individual characteristics, circumstances, and postmortem macropathologic changes. In this retrospective study, based on 1590 consecutive cases of bodies found in water and undergoing autopsy at the Department of Forensic Medicine, University of Helsinki, from 1976 to 1998, the frequency of circumstantial data and macropathologic changes crucial for the diagnosis of drowning were determined. The fatal events were eyewitnessed in 403 cases (25.3%), and suicide notes were found in 83 cases (5.2%). External foam, frothy fluid in airways, and overlap of the anterior margins of lungs were found in 275 (17.3%), 739 (46.5%), and 669 (42.1%) of the cases, respectively, but no one of these changes, tested against dry-land controls, were specific for drowning. The association of external foam and overlap of the lung margins was exclusive of drowning but was observed in only 176 cases (11.1%). After cross-analysis, 964 (60.6%) of the cases had no circumstantial data or macromorphologic pathologic findings that allowed a definite diagnosis of drowning. The diagnostic problems in putative drowning cases, based on this study sample, have not been overrated. Studies to investigate and improve the reliability of complementary methods for the diagnosis of drowning are warranted.

摘要:
Population studies of six short tandem repeat loci were carried out in a sample of unrelated Turkish individuals living in Antalya province, southwest Turkey. After electrophoresis in polyacrylamide gels, 8 alleles could be identified for THO1, 6 for TPOX and CSF1PO, 9 for VWA, 7 for FES, and 14 for F13A01. There was a significant deviation from the Hardy-Weinberg equilibrium between observed and expected values for FES and TPOX loci.

摘要:
Salmonellae most commonly cause uncomplicated cases of gastroenteritis but have a predilection for damaged blood vessels, especially those damaged by atherosclerosis. The abdominal aorta is most frequently affected. The most serious complication ofSalmonellaaortitis is mycotic aneurysm formation with subsequent rupture. The authors present the case of a 61-year-old man who was found unresponsive at home 3 days after discharge from the hospital for treatment ofSalmonellagastroenteritis with bacteremia. Postmortem examination revealed a ruptured mycotic aneurysm with a large retroperitoneal hematoma. Numerous gram-negative rods were embedded in the wall of the aorta and surrounding inflammatory infiltrate, compatible with the patient’s previously isolatedSalmonella. Whereas abdominal aortic aneurysm rupture is most commonly associated with atherosclerosis, the isolation ofSalmonellafrom blood cultures, coupled with radiographic evidence of gas surrounding the aorta, should raise the suspicion of infectious aortitis. Whereas fatal rupture of an aortic aneurysm secondary to atherosclerosis alone or in conjunction withSalmonellaaortitis will not have an impact on the manner of death,Salmonellainfections are reportable and thus have public health implications.

摘要:
The aims of this study were twofold: (1) to measure parameters that contribute significantly to estimates of dental age, using a combination of classic methods and a computer-assisted image analysis procedure to avoid the bias inherent in observer subjectivity; and (2) to develop new mathematical regression models for age prediction according to postmortem interval. Two different populations were studied. Forty-three permanent teeth (Group I), extracted for valid clinical reasons, were taken from patients 25–79 years of age. The other population group (Group II) was composed of 37 healthy erupted permanent teeth obtained from human skeletal remains (age 22–82 years) with a postmortem interval ranging from 21 to 37 years. Morphologic age-related changes were investigated by measuring variables on intact and half-sectioned teeth. Multiple regression analyses were performed with age as the dependent variable for each sample source. In fresh extracted teeth, the variables that made the greatest contributions to predictions of age were dental attrition, dentin color, and translucency width, the latter measured with a computer-assisted image analysis method. In teeth from human skeletal remains, the variables that made the greatest contributions to age calculation were cementum apposition, pulp length measured by computer-assisted image analysis, dental attrition, root translucency, and dental color. We conclude by recommending different regression models to calculate age depending on the postmortem interval.

摘要:
This article deals with the usefulness and limitations of dental identification methods of human burn victims of two buses accidents in Spain. The first accident happened in Bailen in 1996 and involved 28 badly burned Spanish victims. In the second, in Illescas in 1997, 8 Japanese and 2 Spanish victims lost their lives. In both accidents, postmortem forensic procedures for identification were used, including external and internal examination, routine photographs, and dental examination. Dental identification was established in 57% of the cases in the Bailen accident and 80% in the Illescas accident. The success rate of dental identification varies considerably depending on the nature of the accident, the nationality and country of residence of the victims, the incidence of dental treatment, the availability of adequate dental records, and the degree of dental injuries. A discussion of procedures and methods for identification recommended when dealing with burn victims is included.
