Medical Misdiagnoses and
Their Consequences (rev.
9.12.01)
Harold E Buttram, M.D.; Scientific Board member, Autism Autoimmunity Project
Introduction:
As a matter of personal opinion and observation, there is at present a
dichotomy of almost schizophrenic proportions between ongoing American
scientific research in the medical field, most of which takes place in academic
institutions and medical centers, and the genuine needs of the American public.
The scope and direction of this research, most of which is funded by the
National Institute of Health (NIH), is of tremendous importance in that it
forms a source of guidelines and a scientific foundation for the clinical
practice of medicine. In other words, the clinical practice of medicine
as it exists today has been largely shaped by decisions made in the NIH and
other government health agencies in the granting of research money. This
is a system which has existed since the 1930s, but there may be serious
misdirections which are proving to be very costly in terms of the health and
welfare of the American public, especially as applies to its children.
There are two medical conditions from which it is predictable that American
society and economy will be strained to the breaking points in coming years by
overwhelming numbers of medical indigents unless these conditions are addressed
effectively and decisively in the very near future. The two conditions to
which I refer are childhood autism and environmental illness with chemical
sensitivity, neither of which are being recognized for their true nature by
mainstream medicine because of a misdirection of research funding in certain
key areas, as will be reviewed in the following:
Childhood Autism, Predominantly an Environmental Illness
In regards to childhood autism, a condition characterized by severe mental
regression, fifty or so years ago autism was so rare that many pediatricians
had never heard about it. At least this was the experience of Dr. Bernard
Rimland, founding director of Autism Research Institute. In 1956
Dr. Rimland, whose Ph.D. is in research psychology, had a son who was later
found to be autistic. In his annual DAN (Defeat Autism Now)
conferences Dr. Rimland is fond of telling the story about the early days
with his son during which he had great difficulty in finding a pediatrician who
knew anything about or who had ever seen a case of autism. How different
it is now. Childhood autism has become so prevalent that there are very
few who do not know of a family with an autistic child. Families with two
autistic children are not uncommon, and I personally have seen a family in
which all three of the family’s children were autistic. Latest statistics
estimate that over one half million American children are autistic, (1) and
with numbers steadily growing, there is no end in sight. It can be
expected that treatments will improve the outlook of these children, but as far
as is known at present, many or most of these will require custodial care for
life, at an average cost to society as much as three million dollars per child.
(2)
In the opinion of this observer, the misdiagnoses in childhood autism come
not in the diagnosis of the condition itself, something that is unmistakable
once one has seen a few children with the condition, but from a failure to
recognize autism as predominantly an environmental illness. (In this
instance the term, “environmental illness,” is used to include illnesses
brought about by exposures to commercial chemicals and medical interventions as
well infectious microorganisms and other exposures from the natural
environment). This statement is based on a recent seminar on childhood
autism held in the Washington D.C. area as sponsored by the National Institute
of Health and other health agencies September 6th and 7th, 2001, at which the
largest portion of the meeting was devoted to areas of genetics and
neuropathology of autism. (3)
As related to childhood autism, it should be stressed that genetics involves
a susceptibility to autism but, except in rare instances, has nothing to do
with its causes. The same could be said about virtually all epidemic-type
diseases, in which there will be variability in genetic susceptibility.
By their very nature, epidemics always arise from environmental sources of one
type or another and not from genetic causes. Genetic changes take place
very slowly in an evolutionary scale over a period of millennia and never with
the rapid increases as seen today with autism.
Major areas now under suspicion as being causally related to childhood
autism include childhood immunizations, (4) toxic environmental
chemicals, (5) commercial food processing, (6) and the overuse of antibiotics.
(7) The only possible way of salvaging the situation is to find and
modify the causes while at the same time doing the very best we can to develop
effective treatments for those already afflicted with this condition.
Childhood Immunizations – Deficiencies in Basic Science and Safety
Guidelines
As reflected in a series of U.S. Congressional Hearings concerning issues of
vaccine safety which have taken place annually since 1999, (4) there is now
growing awareness of major deficiencies in safety testing for current childhood
immunizations. A few examples will be given here:
(a) Safety studies on vaccinations are limited to short time periods
only: several days to several weeks. There are no (none) long-term
(months or years) safety studies on any vaccination or immunization.
(b) In 1994 a special committee of the National Academy of Sciences (Institute
of Medicine) published a comprehensive review of the safety of the hepatitis B
vaccine. When the committee, which carries the responsibility for
determining the safety of vaccines by Congressional mandate, investigated five
possible and plausible adverse effects, they were unable to come to conclusion
for four of them because they found that relevant safety research had not been
done. Furthermore, they found that serious “gaps and limitations” exist
in both the knowledge and infrastructure needed to study vaccine adverse
events. Among the 76 types of vaccine adverse events reviewed by the IOM,
the basic scientific evidence was inadequate to assess definitive vaccine
causality for 50 (66%). The IOM also noted that “if research…(is) not improved,
future reviews of vaccine safety will be similarly handicapped. (8)
(c) In an article published in Adverse Drug Reaction & Toxicology Review,
(9) researchers Andrew Wakefield and Scott Montgomery, who have been
investigating a possible causal relationship between the MMR vaccine
(measles-mumps-rubella) and the autism enterocolitis syndrome, carefully
reviewed inadequacies of the early pre-licensing trials of the MMR vaccine with
a maximum follow up of 28 days and even shorter periods in some of the
studies. They stressed that such short periods of observation following
the vaccine were totally inadequate to detect delayed reactions, including
pervasive developmental delay (autism), immune deficiencies, and inflammatory
bowel disease, which are known from earlier published reports to occur
following both the natural measles infection and the measles vaccine.
The most interesting feature of the Wakefield/Montgomery article was that it
was reviewed by four leading British authorities, all of whom had previously
held positions in the regulation and licensing of medicines in the United
Kingdom. (10) Taken as a whole, the reviewers were supportive of the article,
three highly so. Peter Fletcher, formerly a senior professional medical
officer for the Department of Health wrote, “being extremely generous, evidence
on safety (of the MMR vaccine) was very thin.” Noting that single vaccines for
measles, mumps, and rubella already existed, he argued, “caution should have
ruled the day…the granting of a product license was definitely
premature.” Professor Duncan Vere, former member of the Committee on the
Safety of Medicines, agreed that the periods for tests were too short.
“In almost every case,” he wrote, “observation periods were too short to include
the onset of delayed neurological or other adverse events.”
(d) In 1984 an intriguing study was reported in a little noted
letter-to-the-editor in the New England Journal of Medicine in which a
significant though temporary drop in T-helper lymphocytes was found in 11
healthy adults following routine tetanus booster immunizations. (11) Special
concern rests in the fact that, in 4 of the subjects, the T-helper lymphocytes
fell to levels seen in active AIDS patients. If this was the result of a
single vaccine in healthy adults, it is sobering to think of the possible
consequences of multiple vaccines (19 within the first 6 or so months of life
at latest count) given to infants with their immature and vulnerable immune
systems. Unfortunately, other than clinical observation, we can only
speculate at these consequences, as the test has never been treated.
Environmental Illness – Deficiencies in Basic Science and Safety
Measures
In my opinion, the second area of misdiagnosis is the common approach of
mainstream medicine in dealing with environmental illness and its related
condition of multiple chemical sensitivity (MCS). In contrast to
the American Medical Association, which denies the existence of MCS as a valid
diagnosis, there is a group of physicians in the field of environmental
medicine who believe that millions of Americans are being made ill and
sensitized in various degrees to toxic airborne chemicals from a class of
chemicals known as volatile organic compounds (VOCs). (12) Illnesses brought
about by breathing these chemicals inside buildings are referred to as “The
Sick Building Syndrome.” A number of official government and health
agency publications have been issued on this subject. (13-18) However, the
major thrust of most of these publications is to stress how little we actually
know about the effects of these chemicals and emphasize the over-riding need
for further safety research in this area. As pointed out in the text,
Multiple Chemical Sensitivity, (National Research Counsel, 1989), “about 70,000
chemicals are used in commerce, of which several hundred are known to be
neurotoxic. However, except for pharmaceuticals, only 10% have had any
testing at all for neurotoxicity, and only a handful of these have been
evaluated thoroughly.” (19)
Since the publication of Multiple Chemical Sensitivity, the situation has
changed in one respect: There is now a substantial body of literature
dealing with occupational exposures to solvent-type chemicals or VOCs,
prominent among which are publications by Lisa Morrow and coworkers at the
University of Pittsburgh, several of which are sited here. (20-23)
For the issue of multiple chemical sensitivity, on the other hand, it is far
different. Once again we are faced with major deficiencies in
safety-oriented studies on the effects of potentially toxic environmental
chemicals on the human system and of safety measures that would have followed,
had these studies been done. Basic science in this area, at very best,
has been fragmentary. For this reason and this reason alone, evidence for
support of the diagnosis of MCS has not yet reached standards of scientific
proof. However, the fact that adequate research has not yet been done to
prove its existence, it does not follow that MCS has been disproved or that it
does not exist. Yet, this is the practical conclusion one generally finds
in mainstream medicine.
Based on my own experiences in many workman’s compensation cases involving
airborne chemical exposures, the near universal response of mainstream medicine
has been to deny its existence.
As a result, many patients with more advanced forms of chemical sensitivity
are becoming like the lepers of ancient times, disabled outcasts of society,
and their numbers are growing larger by the day. (24)
However, we are not entirely barren in this area. Though small in
number and preliminary in nature, there are a number of publications tending to
confirm a widespread presence of MCS in our population, publications
which can form a nucleus for further study. A few of these are enumerated
below:
(a) Two publications involving studies with SPECT brain scans have shown
impairments in brain functions resulting from chemical exposures. (20,25)
(b) In a recent study of a group of veterans with the Persian Gulf War
Illness, an activated coagulation system was found with platelet activation and
fibrin deposits on the endothelial surfaces of blood vessels, which resulted in
a constriction of blood flow. The authors concluded that heavy exposures
to toxic chemicals during the Gulf War in all probability were the underlying
cause of the pro-coagulant state, although other possible causes were also
mentioned in the article. (26)
(c) Studies of patients with chronic fatigue and fibromyalgia at the
Electron Microscopy Unit at the Adelaide Institute of Medical and Veterinary
Science, Australia demonstrated deformities in the red blood cells (RBCs) of
these patients described as dimpled spherocytes (rather than the normal oval
shapes of RBCs) along with increased rigidity of the RBC membranes, these
changes resulting in reduced flow of the RBCs as a result of their deformities.
The article went on to point out that a great majority of these patients had
been exposed to environmental chemicals, some working in chemical factories,
others in wheat fields or orchards subject to periodic pesticide/herbicide
sprayings, many patients noting deterioration following these exposures. (27)
(d) In an article by P Beaune and coworkers, the term “suicide inactivation”
was used to describe the mechanism whereby foreign toxic chemicals may damage
and cripple the enzyme systems necessary for detoxification and elimination of
toxic chemicals. (28) This now thought or suspected of being a major factor in
the pathogenesis of MCS.
(e) Among those working in the field of environmental medicine, (12) The
Environmental Health Center in Dallas, Texas has always been considered a major
center of research in this field. Authored by William J. Rea, M.D., much
of the work of this center has been recorded in a four-volume set of books with
the simple title, Chemical Sensitivity. (29) Many of those familiar with this
center believe it will in time be accredited with being one of the
earliest centers to fully recognize the increasing impact of foreign
chemicals on human health and to do meaningful, systematic study in this area.
With reports such as these now in the scientific literature, further
documentation and confirmation of environmental illness and MCS as valid
diagnoses cannot be long in following, along with a more realistic appraisal of
their prevalence.
Finally, no treatment of environmental illness would be complete without
mention of possible ongoing damage being done to the reproductive systems of
both men and women when exposed to toxic airborne chemicals during their
reproductive years, (30) or of fetal damage when women work in such conditions
during their pregnancies. (5) Although as yet largely theoretical, sooner
or later these are issues which must be addressed.
Conclusions:
In the late 1800s and early 1900s there was a time now referred to as the
golden age of medical diagnosis. Those were the times of Sir William Osler of
Johns Hopkins University, remembered as the father of internal medicine, and of
other stellar names of the times. In those days doctors took time to
listen to their patients, and equally important, took very seriously the
information given by the patient. It was a time of clinical observation,
when doctors believed what their eyes told them and deduced diagnoses based on these
observations. It is no small coincidence that the mythical master of
observation and deduction, Sherlock Holmes, the creation of Sir A Conan Doyle,
was based on a physician that Doyle had known in his student days.
How does this compare with today? Based on personal experience,
very few doctors listen to parents of autistic children, or if they listen to
them, very few believe what they are told by the parents. (31) This is even
truer for patients with environmental illness who, in a majority of cases in my
experience, are commonly referred to psychiatrists or psychologists by their
physicians, their physicians telling them that their symptoms are psychosomatic
or imagined.
However, in defense of doctors directly involved in care of the public, it
is doubtful that there has ever been a time with greater demands on their time
combined with greater economic/political pressures intervening in the care of
their patients than at present. Most of them are doing the best they can
under the circumstances.
I take great pride in being a medical doctor. I would not change
places with anyone in the world. But I also fear for the future of my
profession. Whether in the realm of nature or human affairs, all things
must remain relevant to survive. In the natural world all life forms must
adjust to their environment or perish. In the healing professions,
these professions must both recognize and address the genuine needs of the
public or stand in danger of passing into the limbo of forgotten things.
Actually I believe the medical profession will survive, but to do so will
require a higher level of vision with issues surrounding childhood autism and
environmental illness than has been the norm until now.
For practicing physicians to recognize the nature of their patients’
problems and treat them properly, the physicians must be provided with valid
science by those engaged in research, science realistically directed at the
genuine health needs of the public.

body is centered around two enzyme systems. The first is the P-450 system
which, by a process of oxidization, converts the lipid-soluble state of
volatile organic compounds into a more water soluble form, in which form they
are more readily excreted by the kidneys. There is a price to pay, in that
the water-soluble forms of VOCs may be more toxic than their parent
compounds. In health the second phase of detoxification, that of
conjugation, takes place immediately to neutralize the toxicity in which
process the toxic product is combined with various natural substances in the
body, predominantly glutathione. In many instances in chemical
sensitivity there appears to be a relative deficiency of the conjugation enzyme
activity which results in an accumulation of the more toxic products of phase I
oxidation.

(31) Among the parents with autistic children, a significant portion of these
parents believe that their children have been damaged by vaccines.
A common story in such instances is that the child was developing normally into
his or her second year, was beginning to speak a few words, was affectionate
with parents and playful with siblings until a vaccination took place, after
which the child lost all speech and regressed into a world of its own, no
longer responding to parents or playmates.
As further evidence of such a pattern, during October, 1999 an autism
conference was held in Cherry Hill, New Jersey sponsored by the Autism Research
Institute, referred to as a DAN conference. Over 1,000 people were in
attendance, the great majority of whom were parents of autistic children.
At one point in the meeting, when the chairman asked those in the audience who
believed that their child’s autism was caused by vaccines to stand, a large majority
of the audience rose to their feet. Reportedly there was much the same
response when the same question was asked at the DAN conference in San Diego
during October, 2000.
And yet, this writer has read many evaluations of autistic children from
major medical centers without finding a single instance where vaccines were
mentioned or considered as a possible cause. In those instances in which
parents mentioned their suspicions about the vaccines, apparently they were
ignored.
