Abstract:
The first European case of tetrodotoxin intoxication is reported in a patient who ingested a trumpet shellfish from the Atlantic Ocean in Southern Europe. He suffered general acute paralysis with respiratory failure necessitating ventilation. Early neurophysiologic studies showed complete peripheral nerve inexcitability, with no recordable sensory or motor responses, and normal electroencephalography. Tetrodotoxin was detected in high quantities in the patient's blood and urine through high performance liquid chromatography-mass spectrometry analysis. Seventy-two hours after admission the patient recovered normal strength, reflexes and sensation.
