Medico-legal investigations in Korea depend mostly on postmortem inspection without autopsy. Both untrained physicians and experienced forensic pathologists may not be able to determine the cause and manner of death only by postmortem inspection. The aim of our study was to show the limitations of postmortem inspection by evaluating the discrepancy between the results of postmortem inspection and autopsy after natural death. The manner of death by postmortem inspection changed to unnatural death in 9.4% of the cases (12 cases/127 cases) after autopsy. The cause of death in most cases was consumption of alcohol, agricultural chemicals, and antipsychotic intoxication. The cause of death by postmortem inspection changed in 24.3% of the cases (26 cases/107 cases) among cases of confirmed natural death after autopsy. The positive predictive value of cause of death by postmortem inspection was higher for cardiovascular disease (79.0%) and lower for chronic alcoholism and/or chronic liver disease (28.6%). This study shows that forensic pathologists could make considerable errors in determining the cause and manner of death without autopsy and emphasizes the necessity to refine medico-legal investigations in Korea by introducing the limited autopsy with toxicologic study and supportive postmortem imaging.

BACKGROUND: It is well known that a lacunar infarction has characteristic clinical features and a relatively good prognosis. However, the significance of lesions in the parent artery of patients with lacunar syndrome as regard to the prognosis remains unsettled. METHODS: Using the data of consecutive patients with their first ischemic stroke and were followed longer than 1 year, were divided the patients by their clinical features and the results of the work-up was as follows; (1) mismatching [MM] group; lacunar syndrome and the presence of parent arterial lesion, (2) large artery artherosclerosis [LAD]; non-lacunar syndrome and the presence of parent arterial lesion, (3) no determined etiology [NE]; non-lacunar syndrome without parent arterial lesion, and (4) small artery disease [SAD]; lacunar syndrome without parent arterial lesion. Patients with a potential source of embolism were excluded from this study. The prognosis and recurrence rate of patients with the MM group were compared with those of other groups. RESULTS: A total of 176 patients were included; 56 LAD, 62 SAD, 22 MM and 36 NE groups. An unstable hospital course was more frequently found in LAD than in the other groups. The recurrence rate of the MM group (23%) was significantly higher than that of SAD (2%), but was similar to that of patients with non-lacunar syndrome (LAD 16%, NE 28%). CONCLUSIONS: Among patients with lacunar syndrome, the prognosis of those with parent arterial lesions was different from those without lesions. Therefore, a systematic work up of the stroke mechanism may be important in patients with lacunar syndrome.

Suicidal smothering is distinctly uncommon, especially when caused by winding strips of adhesive tape around the head to cover the nose and mouth. The authors report a very unusual case in which the deceased, a 43-year-old woman, was found with gray adhesive tape wrapped 8 times around the head and strictly obstructed nose and mouse and 2 times around neck. Clear distinction between the homicidal and suicidal smothering by means of multiple loops of adhesive tape is often impossible on the basis of the anatomical findings alone. An accurate evaluation of circumstances, a thorough post-mortem examination, inspection of the scene are extremely important in such cases. We reports a case of suicidal smothering by means of multiple loops of adhesive tape with brief review of literature.

A seaman died after a jet of compressed air directed to his anus while working with his colleagues in deck of the ship. He suffered from abdominal pain and distension, and died 5 hours later in the ship. Autopsy was performed and revealed rupture of the splenic flexure of the colon and partial seromuscular tearing in the rectosigmoidal region. We concluded that the cause of death was tension pneumoperitoneum by the pneumatic colonic rupture. The need for education of the workers handling compressed air appliances is emphasized.

There are more than 120 different theories on the possible cause of sudden infant death syndrome (SIDS). Recent studies indicate a possible role of infections in SIDS, one of which suggested that a maximum percentage of up to 43.5% of SIDS showed virus-induced myocardial affection. The enterovirus, mainly the cardiotropic coxsackievirus group B, serotypes B1-B5, which causes most of viral myocarditis in infancy, seems to be the most common virus associated with SIDS. The aim of our study was to investigate the enterovirus-induced myocardial affections in cases of SIDS. All 7 cases of postmortem heart samples from SIDS victims were studied. Postmortem heart samples of non-SIDS death in perinatal period, infancy and young childhood, pediatric cases of myocarditis and unnatural death in young adult were served as controls. An immunohistochemical study was performed on all samples using monoclonal mouse anti-enterovirus antibody and anti-LCA with quantification of positive cells. Our results demonstrated that 2 of 7 cases of SIDS showed strong immunoreactivity in the myocardium against antienterovirus antibody and there was more inflammatory cell infiltrate in SIDS cases than controls. Our study suggests that the enteroviral myocardial affection would be a possible role in pathogenesis of SIDS.

The optimum timing of surgery for ruptured intracranial aneurysms still remains controversial. In order to compare the total management outcome between early and late surgery a retrospective analysis was carried out. Of 159 patients, 97 patients were selected according to the entry criteria and were divided into two groups ; group I(46pts.) was early surgery planned patients and group II(51 pts.) was late surgery planned patients. The results obtained are as follows ; 1) The incidence of a good recovery for the early surgery planned group was 74%, and that of the late surgery planned group was 67%, but there was no statistically significant difference between two groups. 2) The incidence of a delayed ischemic deficit was 24% for the early surgery planned group, and 29% for the late surgery planned group, with no statistically significant difference. But, the incidence of rebleeding was 2% for the early surgery group, and 14% for the late surgery planned group, so there was a statistically significant difference here. 3) The total management outcome of the early and late surgery planned group was similar, but early surgery was advantageous for the prevention of rebleeding.

Since patients with intracranial neoplasms usually represent their neurological symptoms rather early in the course of the disease, sudden unexpected death due to intracranial neoplasms is an uncommon event seen only exceptionally in medicolegal autopsy practice. Although meningiom is one of the most common primary intracranial neoplasms, sudden death due to the tumor is an uncommon event. We report a sudden, unexpected death of a 56-year-old female with an undiagnosed olfactory groove meningioma. It is assumed that peritumoral edema is related to the sudden death among the several mechanisms.

Carbon monoxide poisoning is probably one of the most common toxic condition to be met with the routine forensic practice. Carbon monoxide is colorless, odorless, tasteless, non-irritating gas whose relative density is a little less than that of air. The most common source of carbon monoxide in death are fires, automobile exhaust, defected heaters, and incomplete combustion of burning products, such as charcoal briquets. Suicidal deaths caused by carbon monoxide are mostly involve inhalation of automobile exhaust and rarely incomplete combustion of charcoal briquets. We recently experienced three cases of suicidal carbon monoxide death by using the carbon monoxide produced by incomplete combustion of charcoal briquets. These deaths were subsequently occurred after forensic medical expert's announcement of accidental carbon monoxide death occurred at shellfish grill restaurant through the television. And we presents four cases of carbon monoxide death with considering of the social effects of forensic medical expert's announcement through the mass media.

Hypopharyngeal perforation associated with traffic accident is a rare occurrence, which can cause serious morbidity and mortality if not diagnosed and treated early. We report an autopsy case of hypopharyngeal perforation following a traffic accident. A 32-year-old man hits his chin when his car hits highway guardrail. He complained continuous neck pain and died 5 days after the accident. Autopsy was performed, and death was due to undiagnosed retropharyngeal abscess with sepsis.

The incidence of sudden death due to undiagnosed primary intracranial tumor is very low in forensic autopsy practice. The ganglioglioma is a well differentiated, slow growing primary brain tumor that is encountered predominantly in childhood. We report a sudden, unexpected death in a 6-year-old girl from a ganglioglioma. On autopsy, there was an intraventricular tumor with recent hemorrhage, occupying the anterior aspect of the lateral ventricle and resulting in hydrocephalus. Acute intratumoral hemorrhage appears to be the mechanism of sudden death.
