September 26, i960 Edward H. Sew, M. D. 5102 Eortli Main Street Houston, Texas near Dew; 1 visited Mr. John Camacho in. Little York Hospital at noon on September 20, i960, to establish whether he had absorbed a significant amount of organic lead, (tetraethyl lead) and!to offer advice in the management of any toxicity problems that might be present. Clinically, 1 felt he had sustained a temporary anesthesia subsequent to the inhalation of petroleum -hydrocarbons aid that he probably had not absorbed a liasardous amount of lead.S I took urine-, and blood samples for quantitative determination ci lead content and advised you to keep him under observation at f the hcsni'tal at least 24 hours. The laboratory reported the following values; brine Blood 0.03 sign Fa per liter 0.03 mgs Fo per 100 m.l. These laboratory values are what might be expected in any normal healthy adult, so we can safely conclude that Mr. Camacho did not absorb a significant quantity,of lead. Sincerely yours. ~r^ b J. G.
