title: [Myokimia induced by gold salts].
abstract: We report a 44 year old male suffering from rheumatoid arthritis that developed myokymias when treated with gold salts. Myokymia is a clinical phenomenon characterized by involuntary repetitive contractions of muscle fibres, which give an undulating appearance to the overlying skin, last a few seconds, and with a typical electromyographic activity described as myokymic discharges. The difference between the single twitch of the fasciculation and the tetanic contraction of myokymia may be evident only on electromyography in difficult cases. Neurological complications associated with gold are infrequent, and they include myokymia, peripheral neuropathy, Guillain-Barré syndrome, cranial nerves paralysis and encephalopathy.
