Driving under the influence of cocaine or therapeutic administration of cocaine?

Introduction: In forensic toxicology, cocaine is better known for its powerful stimulating effects of nervous system and its high potential for recreational abuse, than for his therapeutic use. However, cocaine is still use as a topical anesthetic and peripheral vasoconstrictor in surgeries of eye, ear, nose and throat. Last decade, an increase of the presence of cocaine and metabolites in blood samples of drivers suspected to drive under the influence of drugs (DUID) was observed in Switzerland (Augsburger et al., Forensic Sci Int 153 (2005) 11-15; Senna et al., Forensic Sci Int 198 (2010) 11-16). Observed blood concentration ranges of cocaine and benzoylecgonine were 10-925 μg/L and 20-5200 μg/L, respectively. Since 2005, zero-tolerance approach was introduced in the Swiss legislation for different substances, especially cocaine (analytical cutoff: 15 μg/L). Thus, the interpretation often amounts to determine if the concentration is situated above or under the limit. However, it is important for the interpretation to take into account the context and to be critical with the obtained results, at the risk of ending in erroneous conclusions. Methods: Systematical toxicological analyses were performed on blood and urine, if available, for 5 DUID cases, as already published (Augsburger et al., Forensic Sci Int 153 (2005)). Positive results were confirmed and drugs were quantified in biological samples by GCMS, GC-MS/MS or LC-MS/MS. Results: Administration of cocaine after traffic accident was identified in five cases. All people were admitted to the emergency room because of severe trauma. Maxillofacial surgery was done shortly after admission to the emergency room, involving use of nasal application of cocaine (swab). For all cases, use of cocaine swab was not mentioned in the document filled by the police and by medical staff requested for blood and urine sampling. The information was obtained retrospectively after consultation of the medical records, without precise indication of the application time or dose. Case 1. A 83-year old man (pedestrian) was hit by a car. Blood (+11h after the accident): cocaine (16 μg/L), benzoylecgonine (370 μg/L). Urine: cocaine (1700 μg/L), benzoylecgonine (560 μg/L). Case 2. A 84-year old woman (pedestrian) was hit by a car. Blood (+1.5h after the accident): cocaine (230 μg/L), benzoylecgonine (370 μg/L). Urine was not available. Hair (+4 months after the accident): segment 1 (0-2 cm), cocaine not detected; segment 2 (2-4 cm), cocaine: <0.5 ng/mg. Case 3. A 66-year old man was involved in a car/car accident. He died 2 hours and 5 minutes after the crash. Blood (+1.5h after the accident): cocaine and metabolites not detected. Blood (+2h after the accident): cocaine (1750 μg/L), benzoylecgonine (460 μg/L). Blood (post-mortem): cocaine (370 μg/L), benzoylecgonine (200 μg/L). Urine (+1.5h after the accident): cocaine not detected. Case 4. A 57-year old woman on a motor scooter was hit by a car. She died 2 hours and 10 minutes after the crash. Blood (+0.5h after the accident): cocaine and metabolites not detected. Urine (post-mortem): cocaine (<20 μg/L), benzoylecgonine (120 μg/L). Case 5. A 30-year old man was involved in a car accident. Blood (+4h after the accident): cocaine (29 μg/L), benzoylecgonine (< 20 μg/L). Urine (+4h after the accident): cocaine and metabolites not detected. Ethanol (1,32 g/kg) and cannabinoids (THC (2,0 μg/L), THCCOOH (38 μg/L)) were also detected in blood. Conclusion: To our knowledge, this is the first description of DUID cases involving therapeutic use of cocaine after an accident. These results indicate that even if a per se law is effective for prosecution case of DUID, a critical interpretation of the results is always needed, especially if a medical intervention occurs after an accident.

Autonomía comunitaria y caciquismo: identidad étnica, control social y violencia en una comunidad mixe de Oaxaca

La etnografía de la comunidad mixe de Salto de la Tuxpana y del grave conflicto que se produjo entre 2005 y 2007 es el punto de partida del presente artículo. La investigación realizada arrojó como resultado más destacado el descubrimiento de un violento cacicazgo, legitimado ideológicamente en la autonomía comunitaria, la identidad étnica y el reclamo de una jurisdicción propia, y asentado firmemente sobre tres mecanismos de control social: protección a través de la Policía Comunitaria Armada, acceso a la tierra y acceso a los programas de «desarrollo». El caciquismo se define como el régimen político personalista, basado en estructuras clientelares, que monopoliza y controla recursos y votos. También se propone la hipótesis de que la mayor parte de la violencia desplegada por los caciques es el resultado del proceso de reproducción social del mismo sistema político, cuando se genera una faccionalización simétrica de la comunidad, después de un periodo de estabilidad complementaria.

Petit traité de désobéissance féministe. A l'usage de celles et ceux qui ne viennent ni de mars ni de Vénus

Notre société incite hommes et femmes, dès leur plus jeune âge, à adopter des caractères et des comportements stéréotypés, sous peine de ne plus être reconnus comme de « vrais » hommes et de « vraies » femmes. Ce petit traité de désobéissance féministe a pour ambition de s'interroger sur les représentations contemporaines des sexes de manière à permettre à celles et ceux qui ne viennent ni de Mars, ni de Vénus de désobéir à cette « police des genres ». A la voix de l'auteure s'ajoutent celles d'une cinquantaine de personnalités - journalistes, politicien-ne-s, écrivain-e-s, professeur-e-s, etc. -, qui dévoilent leur rapport au féminisme.

Informe comparatiu del curs de formació bàsica de la policia a Europa. Els casos d'Anglaterra, Alemanya, Bèlgica, França i Holanda

L’informe que a continuació es presenta és una comparativa del Curs de formació bàsica (CFB) de cinc escoles de policia europees. Per a això hem comptat amb la col·laboració de l’Escola de la Policia Metropolitana de Londres (Anglaterra), la d’Hessen (Alemanya), la de Bèlgica, l’Escola Nacional Superior de la Policia Nacional de França i l’Acadèmia de Policia d’Holanda. Per a l’elaboració de l’informe es va utilitzar la informació de què ja disposava l’Àrea de Recerca i Cooperació Internacional de l’Institut fruit de la seva pròpia activitat i, a més, es va enviar un qüestionari a les diferents escoles.

La datation des traces digitales (partie II): proposition d'une approche formelle

«Quel est l'âge de cette trace digitale?» Cette question est relativement souvent soulevée durant une investigation ou au tribunal, lorsque la personne suspectée admet avoir laissé ses traces sur une scène de crime mais prétend l'avoir fait à un autre moment que celui du crime et pour une raison innocente. La première partie de cet article mettait en évidence le manque de consensus actuel dans les réponses données à cette question par les experts du domaine, ainsi que le fait qu'aucune méthodologie n'est pour l'heure validée et acceptée par la communauté forensique. C'est pourquoi ce deuxième article propose une approche formelle et pragmatique afin d'aborder la question de la datation des traces digitales en se basant sur la recherche actuelle dans le domaine du vieillissement de composés lipidiques détectés dans les traces digitales. Cette approche permet ainsi d'identifier quel type d'information le scientifique serait capable d'apporter aux enquêteurs et/ou à la Cour lors de cas de datation des traces digitales à l'heure actuelle, dans quelles conditions, et quels sont les développements encore nécessaires.
