This condition can cause neuropathy, swelling, and pain in the hands and feet in another condition called acrodynia or “pink disease.” While studying this condition (-5[1])in his lab at Caltech, Clair Cameron Patterson used one of the first cleanrooms to discredit earlier findings (10[1])by Robert Kehoe. (10[1])A molecule that causes this condition mimics (10[1])methionine after binding with cysteine, (10[1])allowing it to cross the blood–brain barrier. One form of this condition results in a triad of tremors, (-5[1])gingivitis, (10[1])and erethism. (-5[2])This condition, (-5[1])which is the cause of itai-itai (10[1])disease and (10[2])Minamata (10[1])disease, (10[5]-5[2])is often (10[1])treated (10[3]-5[1])with (10[1])medical-grade (10[5]-5[1])Prussian (10[1])blue, (10[2])succimer, or (-5[1])sodium calcium EDTA (10[1]0[1])in chelation (10[1])therapy. (10[3])For 10 points, (10[1])what condition is (10[1])caused by prolonged exposure to elements (-5[1])like lead (10[2])or mercury? (10[1])■END■ (10[14]0[6])
