title: [Bismuth myoclonic encephalopathies. Their course and lasting or definitive late complications].
abstract: Acute myoclonic encephalopathy related to the ingestion of bismuth salts has been known for 3 years and would appear to be reversible. Of a total of 41 cases, 32 were observed for an average of more than a year. Alongside the commoner benign forms, there coexist severe forms, sometimes fatal, prolonged forms and complicated forms. Permanent deterioration, affecting memory above all, tremor, marked insomnia, headache and disturbed gait are amongst the most durable complications, sometimes definitive, whilst in four cases osteo-arthropathy of the shoulders was associated with permanent invalidism.
