PVP belongs to the substituted cathinones chemical family. These cases highlight the need for emergency physicians, toxicologists and networks of toxicovigilance to control the use of these substances and their dangers, quickly identify cases of severe poisoning associated with the use of new drugs and to develop detection methods.

This human ex vivo model of TBAD is reproducible, since, in all the aortas, extended dissection was achieved and provides the first model of human aortic dissection with infrarenal aorta extension allowing future assessment of endovascular devices developed for human use. Furthermore, it allows clarification of the patterns of aortic dissection propagation and visceral and renal artery involvement according to the site of the primary entry tear.

Typical scenarios of drug-facilitated sexual assaults usually involve victims having ingested a drink after which they had little, partial or no recollection of events for a period of time. We were surprised by the case of a woman who was sexually assaulted and described a state of amazement, leading to an incapacity to resist physically or verbally to her aggressor, and who remembered everything. Alcohol was first suspected but toxicological analysis revealed the presence of 3,4-methylene-dioxy-methylamphetamine (MDMA, Ecstasy). In the literature review, a few cases of sexual assault involving involuntarily MDMA intake are described.

Bare-metal stenting in this model of acute type B aortic dissection was effective in true lumen reexpansion but induced a high (54.5%) rate of significant pressure drop in the visceral and renal arteries when they were supplied by the false lumen.

Background: Respiratory syncytial virus (RSV) is the most frequently identified pathogen in children with acute lower respiratory tract infection. Fatal cases have mainly been reported during the first 6 months of life or in the presence of comorbidity. Case presentation: A 47-month-old girl was admitted to the pediatric intensive care unit following sudden cardiopulmonary arrest occurring at home. The electrocardiogram showed cardiac asystole, which was refractory to prolonged resuscitation efforts. Postmortem analyses detected RSV by polymerase chain reaction in an abundant, exudative pericardial effusion. Histopathological examination was consistent with viral myoepicarditis, including an inflammatory process affecting cardiac nerves and ganglia. Molecular analysis of sudden unexplained death genes identified a heterozygous mutation in myosin light chain 2, which was also found in two other healthy members of the family. Additional expert interpretation of the cardiac histology confirmed the absence of arrhythmogenic right ventricular dysplasia or hypertrophic cardiomyopathy. Conclusions: RSV-related sudden death in a normally developing child of this age is exceptional. This case highlights the risk of extrapulmonary manifestations associated with this infection, particularly arrhythmia induced by inflammatory phenomena affecting the cardiac autonomic nervous system. The role of the mutation in this context is uncertain, and it is therefore necessary to continue to assess how this pathogenic variant contributes to unexpected sudden death in childhood.
