Sellar fracture followed by sudden death: an autopsy case

The authors describe a case of sellar fracture followed by sudden death. The victim was involved in a wrangle. The autopsy revealed facial damage and sellar fracture and no evidence of cerebral damage, except for a mild subarachnoid hemorrhage in the left parietotemporal regions and undersurface of both frontal lobes. Sellar fracture is a rare and severe entity, associated with serious complications, which is frequently diagnosed postmortem. In any case, death is rarely a direct consequence of the sellar fracture itself and is usually considered to be the result of associated cerebral trauma. This case prompted us to screen the literature on sellar fracture to gain a better understanding of the mechanism of death.     

Characteristics of children with problem sexual behaviour and adolescent perpetrators of sexual abuse: a systematic review

ABSTRACT

People who commit sexual offences are a heterogeneous group, with research suggesting that children and young people commit a large proportion of all sex offences, especially those committed against other children. This systematic review provides a synthesis of literature concerning the characteristics of children and adolescents who exhibit harmful sexual behaviour. There is a particular focus in this review on studies that examine the characteristics of children and young people exhibiting these behaviours within institutional and organisational settings or which take a situational and/or developmental approach to understanding sexually abusive behaviour. Using a developmental and life-course criminology lens, this review explores implications from the literature for the prevention and response to child sexual abuse, with a particular focus on institutional contexts where the perpetrators are children and adolescents.     

Rapid analysis of caffeine in "smart drugs" and "energy drinks" by microemulsion electrokinetic chromatography (MEEKC)

A novel method based on microemulsion electrokinetic chromatography (MEEKC) with diode array detection (DAD) for rapid determination of caffeine in commercial and clandestine stimulants, known as "energy drinks" and "smart drugs", is described. Separations were carried out in 50 cm × 50 μm (ID) uncoated fused silica capillaries. The optimized buffer electrolyte was composed of 8.85 mM sodium tetraborate pH 9.5, SDS 3.3% (w/v), n-hexane 1.5% (v/v) and 1-butanol 6.6% (v/v). Separations were performed at a voltage of 20 kV. Sample injection conditions were 0.5 psi, 3 s. Diprofilline was used as internal standard. The determination of the analytes was based on the UV signal recorded at 275 nm, corresponding to the maximum wavelength of absorbance of caffeine, whereas peak identification and purity check was performed on the basis of the acquisition of UV radiation between 200 and 400 nm wavelengths. Under the described conditions, the separation of the compounds was achieved in 6 min without any interference from the matrix. Linearity was assessed within a caffeine concentration range from 5 to 100 μg/mL. The intra-day and inter-day precision values were below 0.37% for migration times and below 9.86% for peak areas. The present MEEKC method was successfully applied to the direct determination of caffeine in smart drugs and energy drinks.     

Transnational Partnerships: What Democracy? Whose Justice?

This article establishes that transnational partnerships should no longer be conceived as peripheral mechanisms of global governance. They have now become increasingly embedded in the multilateral system and a central component in the architecture of global governance. The intellectual progenitors of the partnership discourse have commonly justified governance by partnering as a means to close democratic deficits in global governance. Deliberative conceptualisations, on the other hand, view in the practice of partnering the emergence of a transnational public sphere populated by equal deliberative agents. This article argues that the ideas of democracy and justice ingrained in liberal and deliberative arguments for partnering are at odds with the concrete workings of these mechanisms of governance, which, above all, reflect asymmetrical configurations of power. Drawing on the insights of neo-Gramscian international political economy (IPE), it suggests that partnerships can be best conceptualised as sites of contested authority and frail legitimacy.
