“…In their study of CO poisonings in Wuhan, China, Li et al (44) also found a high proportion of suicides, almost 33%. The study by Wilson et al (43) as well as reporting a high percentage (76%) of completed suicides also reported 701 patients admitted to hospital due to CO intoxication, 49% of which were attempted suicides.…”

Carbon monoxide (CO) intoxications are quite frequent in forensic toxicology. Using a sample of 209 CO-positive deaths in Scotland from 2007 to 2016, this study provides ranges of percentage CO saturations (%COHb) according to the CO source and examines any correlation with age, gender, alcohol, and preexisting disease. It also reports the full toxicological findings, including drug concentrations, in CO-positive cases. The highest numbers of fatalities involved males, occurred during autumn/winter, and the main source of CO was fire. The median %COHb in fire-related cases was significantly lower than in non-fire-related cases such as those involving exhausts, generators and gas supply systems, and portable BBQs. There was no relationship between %COHb and age, blood alcohol concentration, or the presence of preexisting cardiovascular and/or respiratory disease. Toxicology results revealed that prescription medications were the most commonly detected drug group and that the number of cases positive for controlled drugs was small.

“…A recent study found that there might be a cross-regional spreading of new suicide methods via the Internet [ 6 ], and the number of Internet users in China has increased very rapidly in recent years, reaching around 500 million in 2011 [ 7 ]. Forensic studies reported individual cases of CB suicides in some mainland Chinese cities [ 8 – 10 ]. However, there is limited data available about both the incidence of CB suicide and the accessibility of information about it in mainland China in general.…”

BackgroundThere has been a marked rise in suicide by charcoal burning (CB) in some East Asian countries but little is known about its incidence in mainland China. We examined media-reported CB suicides and the availability of online information about the method in mainland China.MethodsWe extracted and analyzed data for i) the characteristics and trends of fatal and nonfatal CB suicides reported by mainland Chinese newspapers (1998–2014); ii) trends and geographic variations in online searches using keywords relating to CB suicide (2011–2014); and iii) the content of Internet search results.Results109 CB suicide attempts (89 fatal and 20 nonfatal) were reported by newspapers in 13 out of the 31 provinces or provincial-level-municipalities in mainland China. There were increasing trends in the incidence of reported CB suicides and in online searches using CB-related keywords. The province-level search intensities were correlated with CB suicide rates (Spearman’s correlation coefficient = 0.43 [95% confidence interval: 0.08–0.68]). Two-thirds of the web links retrieved using the search engine contained detailed information about the CB suicide method, of which 15% showed pro-suicide attitudes, and the majority (86%) did not encourage people to seek help.LimitationsThe incidence of CB suicide was based on newspaper reports and likely to be underestimated.ConclusionsMental health and suicide prevention professionals in mainland China should be alert to the increased use of this highly lethal suicide method. Better surveillance and intervention strategies need to be developed and implemented.

“…Une lecture complète des articles inclus a permis d'exclure secondairement six autres articles. Trois d'entre eux ne présentaient pas suffisamment de données pour effectuer les comparaisons appropriées (Berman, 1979 ;Fishbain, Rao et Aldrich, 1985 ;Jensen, Gilbert et Byard, 2009) et les trois autres ne remplissaient pas les critères de représentativité requis dans la mesure où les cas d'homicide-suicide étaient extraits de l'échantillon de suicides (Guileyardo, Carmody, Lene et Stone, 1994 ;Li et al, 2015 ;Prat, Rérolle et Saint-Martin, 2013).…”

Les homicides-suicides sont des événements aussi graves qu’exceptionnels. À l’interface de la criminologie et de la suicidologie, leur étude et leur prévention butent sur une indistinction de statut : sont-ils à considérer comme une sous-catégorie du suicide ou comme une entité à part entière ? Pour le clarifier, nous avons mené une méta-analyse de l’ensemble des articles comparant les facteurs de risque de suicide et d’homicide-suicide afin de discerner si certains d’entre eux étaient plus spécifiques de l’un ou de l’autre des événements. Treize articles ont été inclus dans l’analyse finale. Le sexe masculin, l’appartenance à une minorité culturelle et les antécédents judiciaires étaient plus spécifiquement associés à l’homicide-suicide qu’au suicide. De même, le suicide survenait plus fréquemment à domicile et impliquait des moyens plus violents lorsqu’il était précédé d’un homicide. En revanche, les problèmes de santé physique, les antécédents de dépression, de tentative de suicide et de consommation de substances psychoactives augmentaient le risque de suicide davantage que celui d’homicide-suicide. À l’appui des présents résultats, nous proposons de revisiter la dualité homicide-suicide/suicide en l’inscrivant dans un modèle intégré. Sous cette perspective, les deux événements pourraient être lus comme l’issue dramatique d’une même tension psychique critique que favoriseraient des facteurs prédisposant aspécifiques. La forme du passage à l’acte ne dépendrait alors de l’influence que de certains de ces facteurs, dits facteurs orientants. Les implications que cette modélisation pourrait avoir en termes de recherche sont ici discutées.
