Abstract:
We report the case of a 48-year-old patient who developed acute onset bilateral, peripheral motor dysfunction in the arms and forearms. Clinical history, electromyography and laboratory tests confirmed the diagnosis of peripheral neuropathy caused by lead poisoning from the domestic water supply. The EMG showed axonal alterations. Improvement was observed after treatments with chelating agents and removal of the source of poisoning. This case provides the opportunity to recall the traditional 1889 Dejerine classification of lead-related peripheral neuropathies and is a warning signal that lead poisoning remains a problem in peri-urban areas of developed countries.
