Hair testing is a useful tool to investigate suspected pediatric exposure to drugs of abuse. Newborns and young children are at high risk of exposure to drugs of abuse from parents or caregivers who consumed these substances, a fact prosecuted by Spanish authorities as child abuse. A retrospective study based on a cohort of 37 cases classified using several parameters, which involve children under 12 years old, were analyzed at the Drugs Laboratory of the National Institute of Toxicology and Forensic Sciences (Madrid, Spain) between 2009 and 2021.

Cardiomyopathies (CMP) comprise a heterogenous group of diseases affecting primarily the myocardium, either genetic and/or acquired in origin. While many classification systems have been proposed in the clinical setting, there is no internationally agreed pathological consensus concerning the diagnostic approach to inherited CMP at autopsy. A document on autopsy diagnosis of CMP is needed because the complexity of the pathologic backgrounds requires proper insight and expertise.

Zip code: 28232, Las Rozas, Spain.

This study advances on overcoming a bias limiting the forensic cases studies of drug-facilitated sexual assaults: a narrow study focus, restricted to assaults affecting young women in leisure contexts related to nightlife, party culture, and dating. A new working framework is applied to analyse data from cases received in the National Institute of Toxicology and Forensic Sciences (Madrid, Spain) over the six years between 2012 and 2017. The work throws light on non-previously described contexts, experiences, and profiles of victims, including domestic cohabitation, labour, education, healthcare, women trafficking, and the daily life of people with intellectual disabilities.

The analysis of drugs of abuse in hair and other biological matrices of forensic interest requires great selectivity and sensitivity. This has been traditionally achieved through target analysis, using one or more analytical methods that include different preanalytical stages, and more complex procedures followed by toxicological laboratories. There is no exception with 2C-series drugs, such as 2C-B, a new psychoactive substance (NPS), which use has emerged and significantly increased, year by year, in the last decades.

The COVID-19 outbreak has represented a challenge for the international scientific community and particularly for forensic sciences. The lack of Coronavirus post-mortem testing led the National Institute of Toxicology and Forensic Sciences (INTCF) from Spain to verify the performance and utility of a quantitative reverse transcription PCR (RT-qPCR) clinical diagnosis protocol for SARS-CoV-2 detection (TaqPath™ COVID-19 CE-IVD RT-PCR Kit), to shed light on the cause of death (COD) in potentially COVID-19 cases in judicial autopsies. Two different RNA extraction methods were also tested (EZ1® DSP Virus Kit on the EZ1® Advanced XL robot versus MagMAX™ Viral/Pathogen Nucleic Acid Isolation Kit) regarding extraction efficiency, precision and contamination.

Article Synopsis
  • Recorded cases of plant poisoning in forensic botany have decreased, but a recent sudden death of a woman involved plant remnants at the scene.
  • An autopsy revealed multiorgan failure, and initial cyanide tests from a suspected yucca-like root were inconclusive, leading to further DNA analysis.
  • The investigation identified the plant as water dropwort (Oenanthe spp.), containing a potent toxin, and combined biological and chemical analyses highlighted the importance of plant evidence in unexplained death investigations.

The analysis of drugs of abuse in hair and other biological matrices of forensic interest requires great selectivity and sensitivity. This is done traditionally through target analysis, with one or more analytical methods, or with different and specific preanalytical phases, and complex procedures performed by the toxicological laboratories, and there is no exception with ketamine-like compounds, such as methoxetamine, a new psychoactive substance whose use has increased in the last decades, and continues to grow quickly year by year. More validated methods of analysis are needed to detect these substances in low concentrations selectively.

The victimization of women by opportunistic drug-facilitated sexual assault in leisure contexts was studied in this work by applying a novel approximation. A multifocal analytical strategy based on an intersectional gender-sensitive approach was used to analyse the evidence coming from both forensic case studies and contextual studies about sexual interrelation and drug use. The process of victimization comprises social changes affecting consumption patterns and sexual interaction, intersecting in the hegemonic recreational nightlife model.

An innovative approach towards the holistic and multidisciplinary study of the victimization of women by drug-facilitated sexual assault has been developed. This phenomenon constitutes a significant problem given the narrowing of the gender gap in drug use over the last few decades and the widespread presence of psychoactive substances worldwide. As violence against women and drug misuse intersect in this phenomenon, this intersectional nature emphasizes the need for a novel approach that enables us to go beyond the studies carried out to date.
