ASBESTOS CASE
Defendant's expert: Dr. Mary Jane Teta
Defense expert Dr. Mary Jane Teta on asbestos case:
Dr. Teta also responds to plaintiffs' arguments contending that plaintiffs'
experts do not follow generally accepted methodology which requires following
the accepted hierarchy of epidemiological evidence. She states that Dr. Panitz
and Dr. Lemen, two of plaintiffs' experts, rely on a weight-of-evidence
approach, akin to the case study approach, which is at best on the "lowest rung"
of scientific evidence and compares unfavorably with epidemiological
evidence.
Dr. Teta opines that plaintiffs' experts base their opinions on (1) case
reports and case series, (2) increased risks of mesothelioma in asbestos exposed
workers in other occupations, and (3) observations of chrysotile in human lungs
and observations of asbestos exposure in garages that install and repair brakes.
These would constitute a reasonable basis for forming a hypothesis related to
mesothelioma and brake work, if the studies had not already been conducted and
the hypothesis rejected.
Biological plausibility cannot be substituted for epidemiological evaluation
according to Dr. Teta. The epidemiological evidence related to chrysotile
exposure in other occupations that plaintiffs' experts rely upon is not relevant
to brake work mechanics or garage workers. The fibers in brakes are shorter,
resin bound, and subject to high temperatures, all of which render them less
toxic than other chrysotile fibers.
Dr. Teta also rejects plaintiffs' expert Dr. Egilman's criticism of Goodman's
meta analysis as selective and industry funded on the ground that neither
criticism is warranted and that Dr. Egilman has developed no alternative that
would show anything different.
