OHIO 4S22B June 23, 1969 ENCLOSURE 6 George Roush, Jr.,, M.D. Medical Director Ethyl Corporation Laboratory of Environmental Medicine 1700 Perdido St. New Orleans, La. 70112 Dear George: ------- The^films-ou-rinsulator&^haY^.arr,iy^d_ftandA^?.;ljjuus t^finished.rqoinq_... over them. Here - are my conclusions; . ' Subject No. 1: In 1956 there is fa jsujpap&aal- lesion ./on the right. The markings to the upper.lungs are a little prominent.- In 1967 the chest appears essentially the same. IMPRESSION: Inactive tuberculosis; no evidence, of asbestosis. No. 2: In 1958 there is apical involvement on the right and multiple tiny scattered calcificationsin theleft upper it lung field. There is a suggestion of honeycombing at the right base. In 1963, the apical lesion on the right has disappeared. Otherwise the chest shows little change. In May 3.968, the honeycombing is more striking and it, is evident at both-bases which are less radiolucent than earlier. IMPRESSION: Inactive tuberculosis; definite evidence of progressive asbestosis in the lower halves of the lung`fields. No. 3: The chest is normal. y1 z' No. 4: The film ismade in expiration. There is pleural thickening obliterating the left costophrenic angle and the markings at the bases are prominent. Whether the latter as-due to mild_.inv.olvement by asbestosis or merely represents the changes of an expiratory phase of respiration cannot be determined. I suggest a new film with deep inspiration. Films No. 5 thru No. 12 are all normal. I am returning the films to. you under separate cover, is enclosed. With best regards, S^iffcerely, My bill ETH 000099 BF/cpb Benjamin Felson, M.D.
