Homicidal manual strangulation and multiple stun-gun injuries.

Stun guns are electric shock devices that are used by a number of law enforcement agencies to subdue violent offenders, but sometimes are discharged into human bodies as offensive weapons. We autopsied a 22-year-old woman who was strangled and had many stun-gun injuries on her head, chest, abdomen, arms, and legs. The stun-gun injuries consisted of many pairs of round erythemas with or without central paleness, some of which were accompanied by circumferential abrasions. To determine whether the electric shocks were administered before or after her death, we studied stun-gun injuries on pigs before and after death and found that the shocks after death did not mark the animal skin. Based on this experiment, all of the stun-gun injuries on the victim's body were concluded to have been inflicted before her death.     

The course of respiration and circulation in 'toluene-sniffing'

To investigate the course of respiration and circulation in death by toluene inhalation, 25 dogs were allowed to rebreathe toluene vapor in a 1-1 plastic bag expanded with air, and electrocardiogram (ECG), electroencephalogram (EEG), blood pressure (BP) in the femoral artery and intrathoracic pressure (ITP) were registered. The respiratory movement continued two times longer than that of death by suffocation using a plastic bag of the same size. In the ECG, low voltage of R waves precipitously appeared several minutes after the beginning of the experiment and continued. The BP gradually reduced by half and kept the level for several minutes. The stage was considered toluene narcosis. Toward the end of the respiratory movement, the BP increased gradually. The analysis of the ECG complexes during the toluene inhalation revealed the direct effect of toluene to the septal and ventricular muscle of the heart. But in the end of the respiratory movement, it revealed ST segment elevation and upright T. In a few experimental animals, some of the transient arrhythmia with fluctuation of the BP appeared during the course, and in one of these dogs, fatal ventricular fibrillation occurred suddenly. These findings suggested that in most cases of sudden death in 'toluene-sniffing', the cause of death is severe hypoxia during toluene narcosis, but in a few cases, it is fatal arrhythmia due to the direct effect of toluene to the heart muscle.     

Blood concentrations of tetracaine and its metabolite following spinal anesthesia

Blood concentrations of tetracaine and its metabolite, p-butylaminobenzoic acid, were measured after spinal anesthesia with tetracaine which had been administered to patients under going orthopedic surgery. Tetracaine, an ester anesthetic, was given to 10 patients, the dose was 8-14mg, and blood samples were collected 1, 2 and 6h after the injection of tetracaine. We used gas chromatography/mass spectrometry for purposes of analysis. Tetracaine was not detected in any blood sample, but the metabolite was detected in each sample with the mean concentrations of 126.5, 97.9 and 43.3ng/ml at 1, 2 and 6h, respectively. This data will be useful in determination of the cause of death after spinal anesthesia with tetracaine.     

Sudden infant death syndrome and hypertrophy of the palatine tonsil: reports on two cases.

Two cases of sudden infant death syndrome (SIDS) with hypertrophy of the palatine tonsil were reported. The pathogenesis of the SIDS has been clarified (Guilleminault et al., Pediatrics, 68 (1981) 354-360). According to this theory, it is due to a central impairment of the breathing control during sleep, which is particularly pronounced in predisposed subjects. The present cases suggest that the hypertrophied palatine tonsil might contribute as a predisposing factor to the emergence of a SIDS by mechanical impediment to breathing by narrowing of the upper airway.     

Imperial subjects,national citizenship,and corporate subjects: cycles of political participation/exclusion in the modern world‐system

This article examines the cycles of political participation/exclusion in modern history. It juxtaposes three cycles of political participation/exclusion—the imperial subject, national citizenship, and corporate subject—with three cycles in the structure of accumulation—the imperialist/colonialist, nationalist, and globalist structures of accumulation. The article argues that the contemporary system of accumulation has dismantled the nation state as the vehicle of economic development and diluted citizenship through neoliberal policies. With eroding state protection, working class people are subordinated to corporations for jobs, consumption, investment, and culture. In order to counter this situation and to achieve emancipation from the capitalist pursuit of profit and rampant consumerism, it is necessary to create alternatives to the contemporary corporate‐dominated system. The article explores sustainable community development as an alternative.     

A delayed drowning death with histological findings of shock

A delayed drowning death case with histological findings of shock was described. The person was sustained by continuous positive-pressure respiration and died 2 days after resuscitation from drowning. The histological findings were intravascular microthrombi, hyaline bodies and fibrin thrombi in the brain, multiple megakaryocytes in the pulmonary capillaries, hyaline membranes of the lung, multiple small hyaline bodies in the liver sinusoids, and erosion of the mucous membrane of the stomach as well as histological findings of shock kidney. Drowning and systemic hypotension during resuscitation seemed to cause irreversible oxygen debt of the organs and the tissues to lead to shock.     

Forensic usefulness of the silicone rubber cast of the cardiac vessels

Adequate examination of the coronary arteries at forensic autopsy is often difficult. No matter whether the arteries are opened longitudinally or transversely, each method has its disadvantages. A technique making silicone rubber casts of the cardiac vessels providing simultaneous angiography is described. The method allows the three-dimensional precise assessment of stenotic lesions of the coronary arteries. It is concluded that the method examined could be useful for the forensic problems.     

Subendocardial small infarct in the superior ventricular septum as a cause of sudden death

In autopsy files from April 1999 to April 2001, five cases showed macroscopic subendocardial small infarct above 1 cm diameter in the superior ventricular septum (SVS) near the atrioventricular (AV) junction, and all five were finally considered to be sudden cardiac death after full investigation. All these small infarcts in these Japanese patients were located at the posterior site of the SVS, an area mainly nourished by branches which ramified from the AV node artery and which branched from the right coronary artery (RCA). Four of the five showed acute (A) or subacute (SA) foci in or around the healed (H) lesion and surviving myocytes were visible in infarcts, in all cases, which suggested a recurrent or chronic prolonged ischemia in the territory. Four of the five had a significant stenosis of the RCA and in the other one, there was an anomalous origin of the RCA. As all five had also small artery disease in the SVS, small infarct of the posterior SVS may have formed by hemodynamic impairment in the territory of the AV node artery caused by RCA disorders. We consider the evidence of macroscopic small infarct of the posterior SVS greatly aids in determining the cause of sudden death in forensic autopsy and may be notable lesion for discussing the pathogenesis of sudden cardiac death with RCA disorder.     

A fatal case of sulindac-induced Lyell syndrome (toxic epidermal necrolysis)

A 37-year-old woman died after 18 days from her starting to take sulindac for low back pain. Based on her clinical course and the autopsy findings, the cause of her death was Lyell syndrome (toxic epidermal necrolysis) induced by sulindac. This case is described together with the legal aspects of medical malpractice to which it gave rise.
