Acute trimethyltin limbic-cerebellar syndrome

Area of Science:

• Neurotoxicology
• Environmental Health

Background:

• Industrial exposure to organotins can pose significant health risks.
• Understanding the neurological effects of specific chemical exposures is crucial for occupational safety.

Observation:

• Six industrial workers developed an acute limbic-cerebellar syndrome following trimethyltin (TMT) inhalation.
• Clinical manifestations were diverse, including sensory and motor deficits, cognitive impairment, and behavioral changes.

Findings:

• The observed syndrome presented with hearing loss, disorientation, amnesia, aggressiveness, hyperphagia, seizures, ataxia, and sensory neuropathy.
• Neurological symptom severity correlated directly with peak urinary organotin concentrations.
• One fatality and severe disability in two patients underscore the potent neurotoxicity of TMT.

Implications:

• This case series highlights the severe neurotoxic potential of trimethyltin (TMT) in an occupational setting.
• Prompt identification and management of TMT exposure are critical to mitigate potentially devastating neurological outcomes.
• Further research into the mechanisms of TMT neurotoxicity and effective treatments is warranted.
