The ultimate causes of idiopathic Parkinson's disease (PD) are not fully known, but environmental and occupational causes are suspected. Postencephalitic parkinsonism has been linked to influenza, and other viral infections have also been suspected to relate to PD. We estimated the relationship between PD and both infections and possible vectors of infection (i.e., animal and human) in a population-based, case-control study in British Columbia, Canada. We recruited 403 cases detected by their use of antiparkinsonian medications and 405 controls from the registrants of the provincial universal health insurance plan. Severe influenza was associated with PD (odds ratio [OR]: 2.01; 95% confidence interval [CI]: 1.16-3.48), although this effect was attenuated when reports were restricted to those occurring 10 or more years before diagnosis. Childhood illnesses were inversely associated with PD, particularly red measles (OR: 0.65; 95% CI: 0.48-0.90). Several animal exposures were associated with PD, with statistically significant effects for cats (OR: 2.06; 95% CI: 1.09-3.92) and cattle (OR: 2.23; 95% CI: 1.22-4.09). Influenza infection may be associated with PD. The inverse relationships with childhood infections may suggest an increased risk with subclinical or asymptomatic childhood infections. Occupational exposure to animals may increase risk through transmission of infections or may indicate exposure to another agent of interest (e.g., bacterial endotoxin).

Therapies derived from fetal tissue research are some of the greatest success stories in medicine. Research using fetal tissue has allowed for development of vaccines for numerous diseases including polio, rubella, and measles. These vaccines have saved countless lives, improved quality of life, and decreased the need for induced abortion secondary to congenital infection. Research using cell lines derived from fetal tissue has assisted in better understanding disease pathogenesis and has served to produce human proteins as research reagents and therapies. Ongoing research points to the potential for fetal tissue to be used to cure debilitating diseases such as Parkinson disease. These scientific and medical advances are dependent on the use of fetal tissue from aborted fetuses. While the practice of induced abortion despite societal benefit may be theologically objectionable to some, these practices are professionally responsible. Federal regulations exist to discourage patients from being influenced by the societal benefit of fetal research in arriving at the decision to terminate as well as to prevent researchers from influencing a patient's decision. After a patient has chosen termination of pregnancy, it is consistent with professional responsibility to allow her to choose the disposition of the cadaveric fetal tissue. While some may view induced abortion and societal benefit from this practice as an ethical burden, the principle of justice makes it ethically obligatory to bear this ethical burden. The success story of cadaveric fetal tissue research and treatment should continue unhindered, to fulfill professional responsibility to current and future patients.
