A promising microbiological test for the diagnosis of drowning

A number of biological and chemical tests have been developed over the years to determine whether a person was drowned. This study focuses on the potential of a microbiological test for detecting common bacterial markers of water faecal pollution such as faecal coliforms (FC) and faecal streptococci (FS) as possible indicators of drowning. A promising previous study was carried out on central and peripheral blood samples of 42 drowned victims (20 cases in saltwater and 22 cases in freshwater) and 30 not-drowned bodies. To improve the accuracy of our previous results and also in order to investigate a possible cause of a false positive due to pulmonary passive diffusion and subsequently endogenous or exogenous bacterial invasion of the blood in the post-mortem interval (PMI), the FC and FS test was applied to bodies submerged in water but died from causes other than drowning. In the present study, blood samples collected from the left ventricle (LV), right ventricle (RV), femoral artery (FA) and, femoral vein (FV) of 10 drowned victims (5 cases in freshwater and 5 cases in seawater) and 3 not-drowned individuals with bodies submerged in water for a while after death have been analysed. Preliminary results are in agreement with other reports dealing with diatoms and marine bacteria that suggest to exclude the hypothesis of a passive penetration of sufficient quantities of drowning medium into circulation after death or during the agonal period. Based on our results there is also no evidence of a relevant dissemination of endogenous micro-flora from the gastrointestinal tract affecting the FS and FC test. There are still several other factors that could influence the applicability of post-mortem FS and FC cultures for the diagnosis of drowning and they need further investigations. The present article provides only a glimpse of the potential of the FS and FC test as bacteriological method for the diagnosis of drowning.

Unexpected perinatal death and sudden infant death syndrome (SIDS): anatomopathologic and legal aspects

This work intends to be a review of the recent histopathological findings elicited by research into sudden and unexpected perinatal death and sudden infant death syndrome (SIDS) that have dictated a novel approach to the inherent problems by pathologists, especially those entrusted with forensic medical authority. The new approach stems from the recent advances made in the understanding of neuro- and/or cardiac-conduction-system diseases present in unexpected perinatal death and SIDS. These demand that an accurate morphologic examination be performed of these structures, which modulate respiratory, cardiovascular, digestive, and arousal activities, in all victims of sudden death. A histopathologic study of an ample register of cases of victims of sudden death, either perinatally or in early infancy, has demonstrated frequent alterations both of the autonomic nervous system (especially hypoplasia of the arcuate nucleus) and of the cardiac conduction system (accessory atrioventricular pathways). The present research provides an in-depth study of the many still-controversial aspects underlying perinatal unexpected death and SIDS and is recommended for professionals working in the forensic field, whose greater insight into this problem will allow more complete medicolegal documentation.     

How “institutionalization” can work. Structuring governance for digital transformation in Italy

Public policy scholars have recently focused on the mechanisms accounting for the sustainability of major policy changes. Among the strategies by which policy entrepreneurs may try to avoid future backlash institutionalization is certainly one of the most used. Yet, it can foster ossification and eventually jeopardize policy effectiveness. Such a potential trade-off between institutionalization and long-term effectiveness is particularly intense in policies concerning technological innovation because the necessity to create winning coalitions can undermine the required absorption capacity needed by government to engage the innovation ecosystems. This paper explores such a trade-off with a case study on the Italian policy for public sector's digital transformation. The case is theoretically promising because over three decades institutionalization has always represented the main overall strategy adopted by policymaker, but only the 2016 initiative emerged as a “success.” In this sense, the case study can focus on the mechanisms activated by policy entrepreneurs to trigger and entrench change.     

Fatal hemorrhage from a periumbilical wound: Stabbing or hemorrhage from a caput medusae?

Varices are the main clinical manifestation of portal hypertension, and their bleeding is the predominant cause of mortality from this condition. Periumbilical varices are known as “caput medusae.” Reports of their bleeding are rare, with only three fatal cases described in the literature. The antemortem diagnosis is relatively simple, while the postmortem diagnosis is more complex. This paper is the first report of fatal hemorrhage from a caput medusae for which the diagnosis was made postmortem, thanks to a complete diagnostic process including scene and circumstances, medical history, and autopsy with detailed histology. The circumstantial analysis showed the presence of a large amount of blood at the scene, blood which originated from a small abdominal wound; an analysis of the subject's clinical data reported that he was affected by portal hypertension. The autopsy revealed some dilated and convoluted veins in the subcutaneous tissue of the umbilical region; a fistula between these veins and the abdominal wound was detected. The histological study confirmed the presence of periumbilical varices, one of them ruptured and connected with the overlying skin. The cause of death was attributed to a massive hemorrhage generated by a periumbilical varix in a patient affected by portal hypertension.     

From Tuscany to Victoria: Some Determinants of Sustainability Reporting by Local Councils

This paper seeks to respond to recent calls by the academic community for studies investigating sustainability reporting by the public sector, as well as for more engagement-based studies of this issue by examining the views of managers within local councils (LC). The objective of this project is to provide insights as to the possible reasons and explanations for the types of sustainability disclosures among a group of local councils operating in Italy and Australia. In particular, an international comparison is undertaken to ascertain the effect of culture on the adoption of sustainability reporting (SR). Evidence is collected from semi-structured interviews with managers and accountants from ten local councils consisting of five from Italy (Tuscany) and five from Australia (Victoria). The findings suggest that although there are available some general policy documents relating to sustainability reporting, councils are left to their own discretion as to what they consider fit under the definition of sustainability and therefore, determine to a large extent, what to report to stakeholders. Moreover, there was a range of legitimacy type behaviours displayed by a number of councils while others were influenced by notions of public sector accountability and transparency. Adopting Hofstede's cultural framework, the research also highlights the relevance of the Italian and Australian cultural settings in shaping the SR practices used by LCs. The findings suggest that differences regarding cultural dimensions, such as ‘power distance’ and ‘uncertainty avoidance’, influence key aspects of SR.     

Conflicts of Rights and Action-Guidingness

In this paper, we raise two points. First, any rights-based theory should provide a method by which to guide reasoning in addressing conflicts of rights. The reason, we argue, is that these theories must provide guidance on what should be done. Second, this method must contain two key recommendations: (1) We should try to find a deliberative mechanism through which none of the rights is simply eliminated from the scene; (2) these rights may be balanced against each other to define which right should prevail, but without considering non-rights-interests as if they were rights in the process. These recommendations instantiate two crucial principles that underlie our common intuitions on rights, namely, the principle that rights deserve equal respect and the principle that rights should be taken seriously.
