Abstract:
Ethylene glycol (EG) is a widely available chemical and a well-known toxin in forensic pathology, which can lead to severe metabolic acidosis and death. Its metabolism in the body leads to formation of calcium oxalate (CO) crystals, which can precipitate in the kidney leading to renal failure. Although the identification of CO crystals in the kidney is widely known, the deposition of CO crystals in other organs has only occasionally been reported and seldom studied. This report examines 18 deaths due to EG toxicity for the presence of CO crystals in various organs. CO crystals were identified most often in the kidneys, followed by the brain and lungs. It is hypothesized that crystal deposition in these other organs may contribute to the toxicity of EG.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Antidotes
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...
