ABSTRACT

AIM OF THE STUDY: To present clinical and analytical aspects associated with sodium azide poisoning. The problems were verified on the basis of a case of sodium azide poisoning which was unique due to its circumstances and the development of an analytical method applied for medico-legal practice. MATERIAL AND METHODS: The object of the study was a toxicological analysis of biological specimens collected from a woman who ingested two doses of sodium azide purchased over the Internet, in a suicide attempt. After the ingestion of the first dose, the clinical management in the form of symptomatic treatment indicated a possibility of recovery. However, the ingestion of a second dose of the xenobiotic, already in the hospital, caused death. Toxicological findings were obtained with the dedicated technique of gas chromatography-mass spectrometry (GC-EI-MS-MS) after extraction combined with derivatization using pentafluorobenzyl bromide (PFBBr). RESULTS: Post-mortem toxicological studies demonstrated sodium azide in the blood (0.18 mg/l) and urine (6.50 mg/l) samples collected from the woman. CONCLUSIONS: Cases of sodium azide poisoning are rare and difficult to treat, but a review of the literature over a longer interval of time shows that they continue to occur. Therefore, case studies of sodium azide poisoning, together with descriptions of research methodology, can be useful both in clinical terms and in the preparation of toxicological expert opinions for medico-legal purposes.

ABSTRACT

AIM OF THE STUDY: In autumn of 2010, in response to an ever-increasing market of "new designer drugs" and in view of new legal regulations, the Sanitary Inspection inspected numerous so-called "smart shops" where such products were sold. In the course of mass inspections, 3545 packages of various preparations were secured on the market in the Malopolska province. A total of 942 preparations were collected for analysis; of this number, 539 were sold as tablets and pills and 403 as plant-derived substances. The objective of the study was to determine potentially psychoactive components of the investigated preparations. MATERIAL AND METHODS: The prepared samples were identified by employing an analytical procedure where the analytes were investigated by gas chromatography-electron impact mass spectrometry (GC-EI-MS) and thus a library of mass spectra was created. RESULTS: The analysis revealed the following substances in the investigated products: piperazine derivatives (BZP, MPMP, TFMPP), cathinone derivatives (N-ethylcathinone, buthylone, ethylone, methylone, buphedrone, flephedrone), pyrovalerone derivatives (MDPV, naphyrone), and synthetic cannabinoids (AM-694, JWH-019, JWH-073, JWH-081, JWH-122, JWH-200, JWH-250). CONCLUSIONS: An unlimited source, i.e. the Internet, continues to provide the worldwide market with preparations of this type and their composition is constantly modified. The scale and complexity of the problem pose a challenge to forensic and clinical toxicology in the field of new designer drugs.

ABSTRACT

The subject of the work included 41 cases of death in which amphetamine was involved as the direct or indirect cause. Identification and determination of xenobiotics in blood samples collected from post-mortem cases were performed by high-performance liquid chromatography coupled with tandem mass spectrometry with electrospray ionisation (HPLC-ESI-MS-MS). Only for two cases was the cause of death amphetamine poisoning. In most of the investigated cases the death was caused by poisoning due to complex amphetamine and other psychoactive substances (e.g. opiates, benzodiazepines, cocaine). In other cases, multi-organ damage (fall from a height, traffic accident), a puncture wound and wound incised, drowning, or asphyxiation by hanging were reported. It can be explained as risky, murderous, or suicidal actions of people who were under the influence of amphetamines. The presented paper focuses on the interpretation of amphetamine concentration in blood samples from the perspective of direct or indirect cause of death.
