[Accreditation of the toxicological screening: recommendations of the SFBC-SFTA group].

Toxicological screening is a specific approach to analytical toxicology that uses analytical tools such as GC-MS, LC-UV (diode array) or LC-MS. Toxicological screening allows the detection and simultaneous identification of a large number of compounds. The results may be based on the use of one or more techniques.

Amitriptyline poisoning of a baby: how informative can hair analysis be?

We reported a case of a 6-month-old baby girl who was hospitalized in the pediatric emergency for central nervous system disorders then coma. Toxicology analysis showed the presence of amitriptyline (AMI) and its metabolite nortriptyline (NOR) in blood and urine of the baby. Additional investigations suggested a shaken baby syndrome.

Variability of voriconazole plasma concentrations after allogeneic hematopoietic stem cell transplantation: impact of cytochrome p450 polymorphisms and comedications on initial and subsequent trough levels.

Voriconazole (VRC) plasma trough concentrations (Cmin) are highly variable, and this could affect treatment efficacy and safety in patients undergoing allogeneic hematopoietic stem cell transplantation (AHSCT). We aimed to describe the intra- and interindividual variation of VRC Cmin throughout the course of VRC therapy and to identify the determinants of this variation. Clinical data, medications, and VRC Cmin (n = 308) of 33 AHSCT patients were retrospectively collected.

Severity of deliberate acute baclofen poisoning: a nonconcurrent cohort study.

Interest in high-dose baclofen treatment for alcohol dependence has increased over the past few years. In the meantime, the rate of acute baclofen poisoning has increased and life-threatening cases have been reported. Thus, severity of acute poisoning could lessen the benefit of baclofen treatment.

[Recommendations for the prescription, implementation and interpretation of medical examinations in biology in the context of severe poisoning].

A multidisciplinary working group named "Toxicology and clinical biology" and whose members belong to the French Society of Clinical Biology (SFBC), Critical Care Medicine Society of French Language (SRLF), the French Society of Medical Emergency (SFMU), the French Society of Analytical Toxicology (SFTA), the Society of Clinical Toxicology (STC), and the National College of Biochemistry (CNBH) updated the professional practice recommendations published in 2003. These recommendations aimed the biologists who are not specialized in toxicology and more largely all the health professionals involved the management of severely poisoned patients. Among the data published in the initial edition, only the major table dealing with severe poisonings was updated, as all other supplements remained valid.

Lack of specificity for the analysis of raltegravir using online sample clean-up liquid chromatography-electrospray tandem mass spectrometry.

Background: Raltegravir is the first antiretroviral agent to target the human immunodeficiency virus-1 (HIV-1) integrase. It is indicated, in association with other antiretrovirals, in the treatment of acquired immunodeficiency syndrome (AIDS) in antiretroviral treatment-experienced adult patients with viral resistance. To evaluate the feasibility of raltegravir therapeutic drug monitoring, we developed a rapid and specific analytical method for the quantification of raltegravir in human plasma by online sample clean-up liquid chromatography-tandem mass spectrometry (LC-MS/MS).
