The most common mistake people make is to subject persons with sensitivities to a reverse onus when they report their experience of repeatable, controllable circumstances, contrary to ethics, social convention and laws since the Magna Carta. This practice is unethical in any context, but becomes especially damaging in clinical medicine.
"An important point is the fear of liability (at the legal and moral level) which perpetrates attitudes and actions. The protective psychological mechanism that comes into action when one knows deeply other people have been harmed, because of their negligence, or because they have been hiding behind the presumed lack of science, because they have minimized, belittled the issues, this mechanism which hides behind denial, camouflage, or aggression needs to be uncovered. Consequences need to be brought to the conscious level, for healing to take place, and prevention to take its role.
“We examined the prevalence of multiple chemical sensitivities (MCS), a hypersensitivity to common chemical substances. We used a randomly selected sample of 1582 respondents from the Atlanta, Ga, standard metropolitan statistical area. We found that 12.6% of our sample reported the hypersensitivity and that, while the hypersensitivity is more common in women, it is experienced by both men and women of a variety of ages and educational levels.
In 1985, Eugene Garfield, PhD, President & Founding Editor of The Scientist provided an excellent overview of medical literature about sensitivities. Garfield documents several approaches, as described in scientific and medical literature before the discussion was subsumed under debate about the approaches of doctors of environmental medicine.
Children with undiagnosed sensitivities, along with other vulnerable people, are being injured and killed in health care. Canadian authorities and Canadian political parties invisibilize protective measures Health Canada was encouraging prior to 1993.
