Toxidromes: Clinical Features

Toxidromes: Clinical Features

Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...

Pharmaceutical Poisoning: Potential Scenarios

Pharmaceutical Poisoning: Potential Scenarios

Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...

Anticholinesterase Agents: Poisoning and Treatment

Anticholinesterase Agents: Poisoning and Treatment

Anticholinesterases, also known as cholinesterase inhibitors, work by blocking the breakdown of acetylcholine, leading to its accumulation in the synaptic cleft. This accumulation indirectly enhances both muscarinic and nicotinic actions. These agents are classified as reversible or irreversible based on their mechanism of action.
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is slower than the...

Drug Toxicity: Risk factors

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

Drug Toxicity: Overview

Drug Toxicity: Overview

Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...

Toxic Reactions: Overview

Toxic Reactions: Overview

When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
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,...

Background:

Mercury poisoning poses significant health risks, with severe outcomes often linked to specific exposure routes and compounds.
Understanding mercury's toxicokinetics and the potential for methylation in humans is crucial for accurate diagnosis and treatment.

Observation:

Two distinct fatal mercury intoxication cases are presented: one from ingesting mercuric chloride solution and another from topical application of a mercury bromide ointment.
Both patients received hospital treatment but succumbed to poisoning, highlighting the severity and rapid progression of acute mercury toxicity.
Autopsy samples were analyzed for total mercury and methylmercury using Cold Vapour Generation Atomic Absorption Spectrometry and HPLC-UV, respectively.

Findings:

Post-mortem analyses revealed substantial total mercury concentrations in tissues and fluids for both cases, confirming mercury poisoning.
Case 1 (mercuric chloride ingestion) showed high mercury levels in the liver, lung, brain, and blood.
Case 2 (mercury bromide ointment) exhibited elevated mercury levels in the liver, lung, brain, kidney, stomach, spleen, heart, blood, and urine.
Methylmercury was exclusively detected in Case 1's liver and blood samples, suggesting limited in-vivo methylation of inorganic mercury.

Implications:

These cases underscore the critical need for stringent control over mercury-containing substances and accurate drug formulation.
The findings emphasize the importance of comprehensive toxicological analysis, including methylmercury assessment, in fatal poisoning investigations.
Further research into human mercury methylation is warranted to fully understand its role in mercury toxicity and long-term health effects.
