In France, drugs are responsible for 40% of accidental poisonings in children and 80% of voluntary poisonings in adults. The annual incidence voluntary drug poisonings is evaluated at 4 per 1000 individuals. Their morbidity and severity have decreased considerably during the past 25 years. A toxic symptom is found in less of 50% of the cases. The fraction of patients hospitalized for drug poisoning mortality is low (0.1%), principally in adult voluntary poisoning. The benzodiazepins are responsible for 80% of the poisonings but they are much less toxic than barbiturates.

Organophosphate (OP) nerve agents, such as soman (GD), pose great risk to neurological health by inhibiting acetylcholinesterase, leading to seizures, epilepsy, and behavioral deficits. While acute treatment may alleviate immediate symptoms, the long-term consequences, particularly those involving neuroinflammation and systemic toxicity, remain poorly understood. This study used adult male and female Sprague Dawley rats to investigate the chronic effects of a single acute exposure to soman (132 µg/kg, s.

Background: In the perioperative period, patients are exposed to many agents that may cause hypersensitivity reaction; so, finding the culprit drug is important for patient safety in the event of the need for repeat anesthesia.
Aim: Our aim was to share demographic data, clinical features, and diagnostic tests of patients who developed perioperative hypersensitivity (POH) and in whom the culprit drug was identified.
Methods: Patients evaluated for POH between 2016 and 2024 were retrospectively analyzed.

All parts of the plant contain the tropane alkaloids hyoscyamine, scopolamine, and atropine together with several minor alkaloids, which cause poisoning such as typical anticholinergic syndrome with neuropsychiatric effects. A review of 114 papers from various databases (Scopus, Web of Science, PubMed, and Google Scholar) revealed that poisoning incidents involving this plant have been relatively common from 2001 to 2024.

Acute liver failure is preceded by severe acute liver injury (ALI) with an increase in transaminases, jaundice, and deterioration in general condition over a period of hours to weeks. Every year 200-500 people develop ALF in Germany, most frequently on the background of toxic liver injury (e.
