Step-By-Step Procedure to Identify Previously Unknown Compounds by LC-QTOF-MS Exemplified by an Intoxication With the Methaqualone Analog SL-164.

In September 2019, a 22-year-old man with a history of drug abuse presented to the hospital with altered mental status. Due to a suspected drug overdose, a blood sample taken on admission and a urine sample collected 30 h thereafter were submitted to our laboratory to test for illegal drugs, pharmaceutical substances, and designer drugs. During the routine toxicological analysis of the serum sample, morphine and phenobarbital were identified by liquid chromatography-quadrupole-time-of-flight mass spectrometry (LC-QTOF-MS).

Frequency of new psychoactive substances in hair and urine samples of individuals subject to drug testing in driving license regranting-A toxicological perspective.

In recent years, numerous new psychoactive substances (NPS) have emerged on the illicit drug market. The assumed non-detectability of these drugs is often a key motivation for individuals subject to drug testing, such as those in driving license regranting programs. In these programs, NPS are not routinely tested for, and thus, subjects who have to prove abstinence from common drugs of abuse might switch to NPS to avoid positive drug tests.

Unexpected results found in larvae samples from two postmortem forensic cases.

Purpose: In forensics, entomological specimens can be used as additional/alternative matrices to detect xenobiotics when human specimens are limited in their application. Despite some advantages over implementing putrefied human remains, most medico-legal laboratories do not include entomotoxicological procedures as routine analytical methods. We thus applied two authentic cases to evaluate necrophagous larvae's potential as complementary matrices for toxicological analysis after extensive postmortem decomposition.

Retrospective analysis of new psychoactive substances in blood samples of German drivers suspected of driving under the influence of drugs.

Driving under the influence of drugs (DUID) is a serious global problem and poses a public health risk. With new psychoactive substances (NPS) entering the illicit drug market several years ago, a significant number of highly potent and harmful drugs have become easily available and the use of these substances may impair a person's ability to drive a vehicle safely. Since NPS are not usually covered in routine toxicological analyses used in DUID investigations, only little is known about their prevalence.

Fatal Immunohaemolysis after the Consumption of the Poison Pax Mushroom: A Focus on the Diagnosis of the Paxillus Syndrome with the Aid of Two Case Reports.

This retrospective report focuses on the diagnosis of the Paxillus syndrome, based on two fatal cases of haemolysis following the consumption of . These mushrooms are still consumed regularly, despite earlier reports of life-threatening autoimmune haemolytic anaemia. Such cases are nevertheless rare, and thus far no toxin could be identified that causes this unusual form of mushroom poisoning.

Mono-/polyintoxication with 5F-ADB: A case series.

5F-ADB is an indazole-based synthetic cannabinoid. In recent years, it has been detected in legal high products as well as in biological samples and is associated with serious adverse health, behavioral effects and even death. Due to the fast pace of the market of synthetic cannabinoids, data on such newly appearing substances are scarce.

The anatomical mummies of Mombello: detection of cocaine, nicotine, and caffeine in the hair of psychiatric patients of the early 20th century.

The Mombello Psychiatric Hospital in Limbiate, near Milan, replaced the old Senavra Hospital as the Psychiatric Hospital for the Province of Milan in the 19th century. During the early 20th century, bodies of several Mombello patients were dissected and preserved by Giuseppe Paravicini, an anatomist who operated within the asylum. The aim of the present study was to examine and memorialize this important assemblage.

Liquid chromatography-quadrupole-time-of-flight mass spectrometry screening procedure for urine samples in forensic casework compared to gas chromatography-mass spectrometry.

This work represents the development, validation, and application of a liquid chromatography-quadrupole-time-of-flight mass spectrometry (LC-QTOF-MS) screening method for the detection of pharmaceutical substances and illicit drugs (acidic, basic, and neutral organic drugs) in urine samples. Time-of-flight mass spectrometry was performed using an LC-Triple TOF 5600 system with electrospray ionization operated in both positive and negative mode, respectively. The limits of detection (LODs), determined for 34 substances, were < 10 ng/mL for 91% of the compounds.
