Fatal paradoxical air embolism diagnosed by postmortem imaging and autopsy

The recognition and visualization of an arterial gas embolism are difficult. We report a case of sudden death caused by paradoxical air embolism of coronary and cerebral arteries, diagnosed by the pre autopsy computed tomography (CT) scanning. A 54-year-old woman suddenly died after the self-removal of the jugular vein catheter. Postmortem imaging examination using CT scanning showed multiple gas embolisms in the cerebral arteries, pulmonary artery, right atrium and ventricle, left ventricle, aorta, and coronary arteries. These findings suggested that the occurrence of acute ischemia of the brain and heart caused by massive air inflow to the artery. Conventional autopsy revealed a patent foramen ovale of the heart. These results indicated that the patient died of paradoxical air embolization of the coronary and cerebral arteries through a patent foramen ovale because of right-to-left shunting. The use of postmortem imaging as an aid for conventional autopsy has proved to be of advantage in the case of gas embolism.     

Case illustrations of negative sexual experiences among university women in Japan: victimization disclosure and reactions of the confidant

A retrospective study of negative sexual experiences (NSEs) was conducted among 532 Japanese university women. More than one third of the respondents reported having experienced at least one NSE, and two thirds were victimized by strangers. When the woman knew the perpetrator well, the NSE was more likely to be repeated. One sixth of victims did not disclose the incident. Older children disclosed incidents more frequently than did younger children. Women in the total disclosure group disclosed the incidents more quickly than did those in the partial disclosure group. Women victimized by strangers were more likely to disclose the incident completely. Less than 10% of women were disappointed with the reaction of the first-disclosure receiver. Unlike results obtained in previous studies, the victims did not necessarily regard it negatively when the incident was viewed less seriously or they were criticized by first-disclosure receivers. On the other hand, instrumental support was not always supportive.     

Proposal for internet-based Digital Dental Chart for personal dental identification in forensics

A dental chart is very useful as a standard source of evidence in the personal identification of bodies. However, the kind of dental chart available will often vary as a number of types of odontogram have been developed where the visual representation of dental conditions has relied on hand-drawn representation. We propose the Digital Dental Chart (DDC) as a new style of dental chart, especially for open investigations aimed at establishing the identity of unknown bodies. Each DDC is constructed using actual oral digital images and dental data, and is easy to upload onto an Internet website. The DDC is a more useful forensic resource than the standard types of dental chart in current use as it has several advantages, among which are its ability to carry a large volume of information and reproduce dental conditions clearly and in detail on a cost-effective basis.     

Systematic Quantitative Literature Review on Criminological Theories in Asia

Empirical work on criminological theories in Asia has been increasing. However, few comprehensive and systematic reviews on the application of criminological theories in Asia have been conducted. Using a systematic quantitative literature review method on peer-reviewed English-language journal articles, we aim to provide an overview of the use of five major criminological theories in Asia: (1) strain; (2) social learning; (3) control; (4) routine activity; and (5) developmental and life-course. In particular, we address the following four questions: (1) how often are these theories tested in which region of Asia?; (2) what methodology is used to test these theories?; (3) to what extent are these theories supported in the Asian context?; and (4) what cultural uniqueness in the Asian context is taken into account in testing these theories, and what role and effect do they play in analysis and outcome? Findings indicate that the relationship between these theories and the Asian regions is skewed; many studies do not employ rigorous methodologies; these theories are either fully or partially supported in the Asian context; and only a few studies have analyzed the cultural uniqueness of the Asian context, and no effect of cultural uniqueness of the Asian context was found. Research implications for developing criminology in Asia are discussed.
