title: [Consequences of thallium poisoning in adolescent].
abstract: BACKGROUND
  Thallium poisoning appears very rare in developmental age and its consequences are quite different. The aim of this study was to characterised the course of thallium poisoning in adolescent and especially electroneurophysiological consequences of it.
  
  
  METHODS
  In a 15 year old boy with sensory-motor polyneuropathy thallium poisoning was recognised in the third week duration of the symptoms. Hemodialysis and hemodiaperfusion were used in the therapy. Data of the repeated electroneurographic and videoEEG examinations were collected.
  
  
  RESULTS
  First electroneurographic data showed axonal motor polyneuropathy. Control after 1 year presented the largest form of the motor-sensory polyneuropathy. On videoEEG tape rejestered in the 5th month of clinical symptoms of poisoning, present were tonic seizures (although EEG pattern was flat with short low voltage theta activity). After next the 3 months of encephalopathy and phenobarbital therapy, voltage of the EEG pattern was slightly higher without any background and seizure activity.
  
  
  CONCLUSIONS
  Thallium poisoning may result with catastrophic clinical consequences of polyneuropathy and encephalopathy. Electroneurographic and electroencephalographic changes 1 year after indicate that clinical consequences of the poisoning are un-remediable.
