The practice of medical toxicology.

Two hundred twelve consecutive cases presenting to a medical toxicologist related to chronic occupational exposure (49%), acute occupational exposure (24%), and nonoccupational exposure (27%). Chief complaints were respiratory (36%), behavioral (28%), neuropathy (17%), and organic brain syndrome (10%). In 90% of patients, litigation was in process or under consideration. Referrals were from plaintiff attorneys (37%), from employers, insurance compounds, and defense attorneys (26%), and from physicians (24%). Outcome of assessment revealed 55% to be unrelated to toxic substances, 39% probably related, and 6% positively related.
