' Tb* undersigned reviewer took part in a clintcal-patbologi-
*
cal conference with'Staff physician at the Cincinnati General Hospital
and tise staff of the laboratory of ileuropathology of that institution
in early aarch.lS^* At that tim- the ealir history of the case, the-;'
clinical record the necropsy findings* the analytical data* and the'-.
report on the gross end microscopic study of the brain were consider*! `
orin detail. The microscopic slides v examined carefully fey the. '
review/c.ad a a m b e r of questions vere raised for discussion. The;
reviewer was not convinced that the microscopic evidence presented ves
sufficient to establish the diagnosis of load encephalopathy beyond
cavil. However it was not possible, to set up another diagnosis that
could be substantiated* and the concensus of opinion of the conference*
with which the reviewer concurred, was that the diagnosis of lead
encephalopathy was justified for both clinical and medico-legal purposes.
A review of the record as submitted has given no reason for
altering this conclusion. It cannot be said that the diagnosis of lead
encephalopathy has been established without question. It is possible
that the- primary clinical condition was hypertensive encephalopathy,
and that death resulted from the hemorrhage. However, the hemorrhage
is regarded by the neurologists and the neuropathologists as incidental
in this case, and that conclusion cannot be proved erroneous.
Against the diagnosis of lead encephalopathy is the opinion
of Dr. viatuska who regarded the condition as primarily hypertensive,
