Dr. Richard Parent is certified in toxicology by the American Board of Toxicology and the Academy of Toxicological Sciences and has been providing litigation support to both plaintiff and defense since 1984. Current projects include PCBs, Dioxins, Vinyl Chloride, Benzene, Toy Safety, REACH, Creosote, Manganese, Vioxx, Chromium, Medical Surveys and Evaluations.

Dr. Parent has been providing litigation support for both Plaintiff and Defense and Product Safety consults since 1984. His credentials have been accepted in every court in which he has testified and he has qualified as an expert both in Toxicology and in Chemistry. Dr. Parent is Board Certified by the American Board of Toxicology, the Academy of Toxicological Sciences, the Regulatory Affairs Certification Board and is a recognized expert in Toxicology in both France and the entire European Community. More detail on his background may be found by consulting his curriculum vitae.

Dr. Parent is an expert on matters of causation and he frequently lectures on the subject. Samples of his expert causation reports may be found under the heading of “articles” indicated above. He has been involved in a number of different legal cases involving a variety of chemicals and Drugs including Tobacco Smoke, Welding Fumes, Diesel Fumes, Manganese, Chromium, Nickel, Arsenic,Fen-Phen, Vioxx, Pcbs, Dioxins, Solvents, Vinyl Chloride, PVC, Pesticides, Pantopaque, PPA, Ephedra, Baycol, Sporonox, Lindane, Parathion, Acrylonitrile, Phosgene, Ammonia, Ozone, Trichloroethylene among others.

In addition to these relatively straight forward toxic tort cases, Dr. Parent and his team have provided Technical Management and Direction in cases of complex environmental contamination and resulting personal injury. In addition, with his Medical Team, he has conducted health surveys, blood samplings for toxicants and clinical parameters, and medical examinations of individuals exposed to toxicants in a number of different situations. More details on these and other projects are found below.

Dr. Parent will provide you with an initial consultation without charge. Feel free to contact him and discuss your cases.

Special Projects
Technical Management of Mass Toxic Tort Litigation Frequently, in complex cases of this type, usually involving environmental contamination, adverse drug reactions or occupational exposures, the attorneys involved attempt to provide technical direction resulting in waste and inefficiency. Dr. Parent will first technically evaluate a case to determine if general causation can be established in the courtroom relating the agent(s) involved in the exposures and the suspected health effect. A decision to proceed at this point affirms the validity of the case. Next, exposure of the population under study must be established beyond doubt. This may require environmental sampling, industrial hygiene surveys or simply good pharmacy records depending on the nature of the case. Once exposure is established, then a health survey should be conducted and would initially involve the circulation of a medical questionnaire specifically designed by Dr Parent to address the specific situation. Once the questionnaires have been evaluated, it may be necessary to evaluate the patients medically to firmly establish diagnoses and eliminate alternative causation (Differential Diagnoses). If the chemical or drug in question is persistent in the body, body fluid analyses may be recommended. Once these activities are completed, causation reports may be written and the individual plaintiffs will be rated based on combinations of exposure, seriousness of illness, and strength of specific causation relationship. This will allow the attorney to structure an appropriate settlement based on the rating scale for his clients.

From the Defense viewpoint, Dr. Parent has conducted these investigations and knows what is required to bring about appropriate settlements in these complex cases. Consequently, his oversight of plaintiffs efforts can identify weakness in the opposition’s approach to the task at hand and thereby provide a favorable position if settlement negotiations become appropriate.

Medico-Toxicology Team
Dr. Parent has assembled and manages a team of experts to deal with health issues related to possible exposure to environmental chemicals, prescription drugs, or occupational exposure situations. When evaluating potential health effects of numerous individuals, uniformity of approach is critical. We have already discussed the need for a health survey form designed specifically for the situation at hand, the next step in the evaluation could involve a medical team. Dr Parent has worked with a team of experts including nurses and phlebotomists, and a diagnostic Physician to conduct physical examinations. Auxiliary testing may be required and additional expertise is available to conduct specialized testing. Also, if body fluid analyses are required, Dr. Parent is highly capable of choosing laboratory alternatives to provide the most reliable findings. Dr. Parent has also qualified as an expert in Chemistry. Once the data on the individuals is assembled, medico-toxicological data interpretation will result in a rating of the individuals based on defined criteria so that the approach can be justified to the court.

Arbitration of Complex Toxic Tort Litigation

Toxic tort cases involving adverse drug reactions, or exposure to occupational or environmental chemicals are very complex and very expensive to litigate. In these cases, establishing exposure and a causal link between the alleged disease and the chemical or drug exposure is the key to a successful plaintiff’s case, particularly in the Federal Courts with the requirements of Daubert and Havner in Texas.

These cases usually involve physicians diagnosing various disease thought to be related to the exposure, sometimes industrial hygienists elucidating the exposures, and toxicologists on both sides to evaluate the merits of the case relative to causation. Under these circumstances, it is difficult, if not impossible for the attorneys and the courts, neither of whom are normally technically trained medicine or science, to determine what is real in the case. Thus, there is a role here for an unbiased technical consultant to come in and evaluate the situation and provide both sides and the court with an assessment of the situation. The procedures that we would follow in fulfilling this role are indicated below. This effort could be carried out independently or in conjunction with a qualified arbitrator.
▸ Acquire and evaluate all records from both sides including medical records, records relating to exposure to the chemical or drug and timing of dosing and reaction(if any).
▸ Assess past medical history and familial medical history for possible impact on the causation issue.
▸ Acquire and evaluate all pertinent expert reports and depositions relating to the case.
▸ Acquire and evaluate all pertinent literature acquired by both sides and initiate and acquire additional peer-reviewed literature as needed.
▸ Presentation of findings to both sides and to the Court, if appropriate.
▸ Point out weaknesses and strengths of both cases from the scientific viewpoint with special emphasis on issues related to causation
▸ Provide oral or written evaluation of the case to concerned parties.
▸ Openly discuss the findings with all concerned parties and aid, if appropriate, in settlement discussions.

Dr. Parent has been studying causation and testifying on both sides on matters related to causation since 1984. The perspective that he has gained over this expanse of time could be a significant asset in the equitable settlement of these complex and costly cases.
