Sudden Death Secondary to an Undiagnosed B‐Cell Lymphoma of the Hypopharynx and Infiltration of the Inferior Constrictor Muscle

The aim of this presentation was to share an uncommon form of sudden death, suffered by a 64‐year‐old woman, due to a mechanical obstruction of hypopharynx by an undiagnosed B‐cell lymphoma, infiltrating the inferior pharyngeal constrictor muscle. A forensic approach by means of scene investigation, circumstantial data collection, autopsy, and histological and toxicological investigations led to conclude that the cause of death was asphyxia, correlated with B‐cell lymphoma of the hypopharynx. The autopsy examination highlighted the presence of a wall thickening, infiltrating, and projecting into the hypopharynx lumen. The histological analysis showed the essential finding of a B‐cell lymphoma of the hypopharynx, diffusely infiltrating the inferior pharyngeal constrictor muscle. To conclude, this case demonstrates once more that in the absence of specific data, a thorough forensic investigation including autopsy, histological examination, and circumstantial data collection is mandatory to reach a correct cause of death.     

Forensic Epidemiologic and Biomechanical Analysis of a Pelvic Cavity Blowout Injury Associated with Ejection from a Personal Watercraft (Jet‐Ski)

Jet‐propelled personal watercraft (PWC) or jet‐skis have become increasingly popular. The means of propulsion of PWC, which is a jet of water forced out of small nozzle at the rear of the craft, combined with a high risk of falling off of the seat and into close proximity with the water jet stream, raise the potential for a unique type of injury mechanism. The most serious injuries associated with PWC falls are those that occur when the perineum passes in close proximity to the jet nozzle and the high‐pressure water stream enters the vaginal or rectal orifice. We describe the forensic investigation into a case of an anovaginal “blowout” injury in a passenger who was ejected from the rear seat position of a PWC and subsequently suffered life‐threatening injuries to the pelvic organs. The investigation included a biomechanical analysis of the injury mechanism, a summary of prior published reports of internal pelvic injuries resulting from PWC falls as well as other water sports and activities, and a comparison of the severity of the injuries resulting from differing mechanisms using the New Injury Severity Score (NISS). The mean (±standard deviation [SD]) NISS values for reported PWC injuries [not including the NISS of 38 in this case study] were 11.2 (±9.5), while the mean value for reported water‐skiing falls was half that of the PWC group at 5.6 (±5.2). It was concluded that the analyzed injuries were unique to a PWC ejection versus other previously described non‐PWC‐associated water sport injuries. It is recommended that PWC manufacturers help consumers understand the potential risks to passengers with highly visible warnings and reduce injury risk with revised seat design, and/or passenger seat “deadman” switches.     

Globalization,State Autonomy and the Fight against Cross-Border Crime: Greater China's Cooperation with the World

Although globalization has stimulated the rise in cross-border crime, it does not really undermine the autonomy of the mainland Chinese state, the Taiwan state, and the city-states of Hong Kong and Macao. Instead, through cooperation with law-enforcement agencies in other countries, the law-enforcement agencies of these four places, notably the police and customs, have ensured the persistence of state autonomy vis-à-vis cross-border criminal groups and individuals. In the case of Greater China (mainland China, Taiwan, Hong Kong and Macao), interstate cooperation involving the police and customs can maintain state autonomy vis-à-vis criminal groups and individuals. The mechanisms of such interstate and intergovernmental cooperation embrace the sharing of criminal intelligence, the occurrence of anti-crime joint operations, the holding of seminars and conferences, and the administrative arrangements of extraditions. In a nutshell, intergovernmental cooperation in the combat against cross-border crime can maintain state autonomy in the midst of globalization, as the case of Greater China shows.     

Restricting loans of money to Hong Kong civil servants: social censure or violation of human rights?

Obtaining a loan is an individual’s private business and such a right should be free from interference. However, if Government officers obtain a loan from undesirable persons, they may be lured into committing an act which they would not otherwise have done but for the favours having been shown by the lenders. Section 3 of Hong Kong’s Prevention of Bribery Ordinance attempts to limit such behaviour of Government officers. Since the power of this provision is draconian, it may possibly violate human rights. This paper attempts to use a Social Censure perspective to explain why this provision was put in place in the 1970s and why it was not repealed in the 1990s in line with the rise of human rights standards in Hong Kong. It argues that the then British colonial government used a high-hand legal code to fight against corruption in the civil service to win its legitimacy in face of the rise of Red China in the 1970s. A review of twenty-one Section 3 cases suggests that most of the loans were not distributed for mere friendship but involved a wide range of culpability. Thus the coercion generated by Section 3 was approved by the masses, resulting in the reinforcement of a draconian but efficient legal provision in the service of the colonial administration.     

Colonization of diatoms in and on porcine bone substrate and considerations of diatom ecology for forensic science

The presence of diatom algae in bone marrow has been used as forensic evidence of drowning for several decades; however, these studies are based on known or suspected recent drowning events. This study addresses the potential for diatoms to enter the bone marrow of skeletal remains, that is, de-fleshed long bones post-mortem. In laboratory and field experiments, bones were either inflicted with two access points by a cut and acid pitting or left intact. The bones were submerged in water for at least 1 week and up to 3 months. Samples of the bone surface and marrow were inspected for diatoms. The analysis considered the time required for diatoms to enter marrow and whether genus characteristics like size or mobility affect entry. The presence of an access point influenced diatom entry in that bones without an introduced access point had zero to one diatom present in the marrow, whereas a bone with an access point had >150 diatoms present in the marrow. The results of both laboratory and field phases suggest that diatoms will reliably colonize bone in as quickly as 1 week, establishing and maintaining communities for at least 3 months. However, the bone surface assemblages differ from the source community. Bone marrow displayed even more restrictive access to diatom colonization, resulting in communities dominated by small raphid diatoms. Based on these findings, we suggest some caveats on the use of diatoms as trace evidence in forensic science with recommendations for future avenues of research.
