PFPC NEWSLETTER #9:
"Fluoride, Gingivitis & Oral Cancer"

http://64.177.90.157/pfpc/html/newsletter_9.html
Summary:
Gingivitis and periodontal disease are the oral diseases
requiring most urgent intervention. Over 90% of the U.S.
population over 13 is affected. Strong links have been made to
heart disease and low birth weight and infant mortality. For
heart disease the association with gingivitis is stronger
than the one for smoking or high cholesterol. As heart disease
is the #1 killer in the US, many efforts are undertaken to
reduce this alarming figure. In Canada large pictures of a
diseased heart are placed on cigarette packs alerting to the
fact that smoking causes heart disease.
It is of great importance that warning labels and pictures of
periodontal disease, oral cancer, diseased hearts, pituitary and
thyroid glands, as well as Alzheimer’s brains - just to name a
few - are placed on all oral care products containing
fluoride.
Why?
A patent by the pharmaceutical company
Sepracor
discloses that concentrations of fluorides from fluoridated
toothpastes and mouthwashes activate G proteins in the oral
cavity, thereby promoting gingivitis and periodontitis, as well
as oral cancer. Incomprehensibly, this vital information is
being withheld from the public by all parties involved,
including the company, at least two well-known Universities, and
numerous oral disease experts. This includes a much-decorated
ADA scientist who was involved in setting the CDC
recommendations for fluoride intake in children, served as head
of a Food and Drug Administration subcommittee that decides
which dental products to make available to the public, and who
chaired the panel on safe use of fluoride for the Centers for
Disease Control (CDC, 2001).
An extensive section of this Newsletter deals with
biochemical aspects [Part 4].

INTRODUCTION
Many of our children have experienced oral diseases which
miraculously disappeared when fluoride intake was curtailed. For
example, some had consistent “white spots” on their gums which
vanished upon elimination of fluoridated toothpaste, but
returned as soon as such toothpaste was used again.
Some of these white spots and patches were diagnosed as
pre-cursors to oral cancer (squamous cell carcinomas),
while others were deemed to be "allergic reactions" by medical
professionals. Yet other doctors identified oral yeast
infections (Candidiasis).
When we investigated the scientific literature on fluoride
toxicity we found that such oral conditions have been related to
fluoride intake countless times. There is extensive evidence of
such disease in humans from areas with water fluoridation, from
toothpaste and mouthrinse use, as well as in workers exposed to
fluorides.[See:Part 3]
Studies in workers exposed to fluoride have shown that the
severity of periodontal disease is directly correlated to
the fluoride levels in systemic fluids (i.e.
Domazalska, 1972). The more fluoride in the system - the
more severe the periodontal disease. The same findings have been
made for
Asthma.
THE PATENT
In 1996 three biochemists (Aberg,
Jerussi & McCullough, 1998),
working for the pharmaceutical company
Sepracor,
speculated on fluoride implications in periodontal disease.
Realizing that fluorides activate G proteins, they reasoned
that fluorides would also be involved in the activation of those
G proteins which regulate the pathways involved in gingivitis
and periodontitis - and they decided to test for the ability of
fluoride to activate two integral receptors involved in
periodontal disease - the prostaglandin E2 receptor (PGE2)
and the thromboxane A2 (TXA2) receptor. Both are coupled
to G proteins called
G q/11.
The scientists conducted a test with sodium fluoride based on
a well-established in-vitro protocol model involving
HL-60
cells. These are Human Leukemia cells often used
in biochemistry investigations, as one can observe fundamental
and critical signals involved in the activation of the body's
immune system - because of the cells’ ability to respond to
foreign organisms.
The authors reported:
-
"We found that fluoride, in the concentration range in which
it is used for the prevention of dental caries, stimulates
production of prostaglandins and thereby excaberates the
inflammatory response in gingivitis and periodontitis....
Thus, the inclusion of fluoride in toothpastes and
mouthwashes for the purpose of inhibiting the development of
caries may, at the same time, accelerate the process of
chronic, destructive periodontitis."
A very important finding as it relates to public health!
In the 1986 National Institute of Health (NIH) survey, 93% of
adults indicated that their children used toothpaste with
fluoride, obviously putting all at risk. Gingivitis and
periodontal disease constitute THE major public oral health
problems in the US.
The patent findings supply the biochemical explanation for
earlier reports by many researchers who had found increased
gingivitis and gum inflammation due to fluoridated water, or
other sources of fluoride.
Even T. Dean himself - the so-called "Father of
Fluoridation", made such observations.[see: Part 3]
However, instead of alerting the public health officials to
their findings, those men apparently decided to take another
avenue.
They went looking for an agent which would counteract the
adverse effects of fluoride and therefore could be used together
WITH fluoride. After all, fluoride was/is the "proven caries
fighter"!
They chose a non-steroidal anti-inflammatory agent (NSAID)
called ketoprofin, conducted more studies to see
if ketoprofin was efficient in off-setting the damaging fluoride
effects, and then filed a patent on their new concoction now
containing both fluoride and ketoprofin (Aberg et al,
1998).
Subsequently, a study was instigated at the Harvard School of
Dental Medicine (funded by Sepracor), documenting
the ‘wonderful’ effects of ketoprofin upon gingivitis. The first
study on beagles included one of the three co-inventors
(McCullough) together with two Assistant Professors from two
separate well-respected Universities, and was subsequently
published in the Journal of Clinical Periodontology in 1997
(Paquette et al, 1997).
In the study not one word is mentioned about fluoride being a
causative/promoting agent of gingivitis, as stated in the patent
claims.
Another study - this time on rats, and again as a direct
result of the patent research - was conducted involving yet
another of the three co-inventors from Sepracor
(Jerussi).
This time the study was done with two professionals from the
University of Rochester, one being
Prof. Bowen,
the much-adorned and decorated ADA scientist involved in setting
the 2001 CDC recommendations on fluoride intake.
Results of this study were published recently in the Journal
of Oral Diseases (Bowen et al, 2000)

Again, not one single word about fluoride promoting and
causing gingivitis appears in the entire text.
GINGIVITIS - Statistics
According to the National Institute of Dental and
Craniofacial Research (NIDCR; Brown et al, 1996), over
90% of persons 13 years or older experience some form of
periodontal disease.
74.9 % of all people between 35 and 44 years suffer from
periodontal disease (Fig.4.7,
Oral Health Report, 2000). 29% of males and 15 % of females
between 35 and 44 years old have destructive periodontal
disease (Healthy People 2010-Conference Edition).
60% of all people between 18 and 44 suffer from periodontal
disease (Figure
4.8, OHR).
Compared to these figures - up to 46% of adults over 18 years
old have untreated caries (Figure
4.5, OHR).
Not surprisingly, periodontal disease has recently become the
primary focus for dental researchers because of the very strong
links which have been made to other conditions such as heart
disease (Loesche 1994, 1998; Herzberg and Meyer 1996), as
well as infants with low birth weight and premature births. For
heart disease the association is stronger than for smoking
(Loesche et al, 1998).
The NID(C)R, in their 1999 appeal to the Appropriation
Committee for $276,518,000 in funding, stated that gum
disease is now also known as a high risk factor for low birth
weight babies. Said Crawford in his plea for the big money:
-
"Care of low birth weight babies costs the nation
approximately $5 billion dollars each year. If we can lower
the incidence of low birth weight babies by treating gum
disease it will mean that 1:10 babies born in the US have a
better chance of a healthy start in life."
Further, he reasoned:
-
"As we come to the end of this, century, 50% of heart
attacks (the number one cause of death in the Western World)
and 25% of low birth weight babies have no aditional risk
factors associated with them. We now have strong evidence
that gum disease is a risk factor for both these conditions
- in fact - as strong a risk factor for heart disease as
elevated cholesterol or smoking!"(Crawford, 1999)
This clearly means that fluorides - by promoting gingivitis -
also contribute to heart disease and low birth weight. Heart
disease has long been known to be higher in workers exposed to
fluorides, or caused by fluorides in medications
(PFPC, 2001).
Biochemical investigations have identified the pathways.
The patent findings implicating the fluoride "topical"
activation of G proteins in the oral cavity have many
far-reaching and serious implications - not only for periodontal
disease, but also for oral cancers - which involve "mutated" G
proteins, and which are activated by fluoride, often even
"preferring" fluoride activation.[see Part 4: Biochemistry]
ORAL CANCER - Statistics
Oral cancer is the sixth most frequent cancer in the world
(Buffalo Sisters Hospital, 2000).
Oral cancer claims the life of one American every hour. Over
thirty thousand Americans are diagnosed with oral or pharyngeal
(throat) cancer every year and 8,000 people die annually from
these cancers. Only half survive more than five years. This
overall 5-year survival rate (52 percent) has not changed
in the past five decades - coincident with the appearance of
fluoride as a ‘preventive treatment’ for caries.
Black people have higher incidence and mortality rates than
other subgroups (OHR, 2000; Caplan et al. 1993; NIH Press
Release, 1996), as they do with most thyroid hormone-related
disorders, including, of course, "dental fluorosis" (PFPC,
2000).
“White Patches” - Cancer
As was mentioned in the INTRO, many of our kids have had
these "white patches" in the mouth, often diagnosed as
"precursors" for an ‘oral squamous carcinoma’.
A benign squamous papilloma is the obligate precursor
of squamous cell carcinoma, and again, numerous laboratory
investigations have shown that these are brought about by
fluoride. Mere ras oncogene activation is sufficient to
produce the papilloma phenotype in skin cancers, and fluoride is
known to act additively with the ras oncogene in
producing this papilloma (Camp & Hoffman, 1993). (-> Cancer
promotion).
[see Part 4: Biochemistry]
Part 2
FLUORIDATION AND ORAL CANCER
In 1981 Dr. John Yiamouyiannis and
Dean Burk,
chief chemist emeritus of the National Cancer Institute (NCI),
first showed very convincingly that there was an increase in
oral cancer in fluoridated areas.
An investigation done by the Battelle Institute on behalf of
the National Toxicology Program (NTP) (NTP, 1991; also see:
Yiamouyiannis, 1993) showed a clear dose-response
relationship between oral cancers and fluoride intake in the
animals tested.
According to the late Yiamouyiannis, the National Cancer
Institute (NCI) - in response to the NTP findings - decided to
examine the incidence of oral cancer in fluoridated and
non-fluoridated areas. The resulting data showed at least a 33%
to 50% increase in the incidence of oral cancers in fluoridated
areas, indicating at least an additional 5000 - 7500 or more
cases or oral and pharyngeal cancer per year as a result of
fluoridation alone (Yiamouyiannis, 1993).
Table
An increase in oral carcinomas and their precursors has also
been observed in workers exposed to fluorides.[see next
section]
Part 3
BRIEF LITERATURE REVIEW - EVIDENCE
(Compiled by Wendy Small)
Gingivitis and oral diseases due to fluoride excess have been
reported many times in the world literature.
In 1936 Dean - the "father of fluoridation" himself - wrote
in the Journal of the American Medical Association:
-
"From observations that I made in areas of relatively high
fluoride concentration (more than 4 parts per million of
fluorine) there is sufficient evidence to suggest that there
is an apparent tendency toward a higher incidence of
gingivitis."
Remember, at that time water with fluoride at 4ppm was
thought to produce a total intake of 4 mg/day. In 1991 the US
PHS estimated that TOTAL intake exceeded 6.5 mg/day in U.S.
cities having one part per million (1ppm) of fluoride in their
water supply!
Similar observations of the link between fluoride and
periodontal disease have been made many times since (Dean &
Arnold, 1943; Day, 1940; Spira, 1953; Ramseyer et al, 1957; de
Toledo, 1970; Grimbergen et al, 1974; Poulsen & Moller,1974;
Waldbott et al, 1978; Olsson, 1979; Reddy et al, 1985; Wei et
al, 1986; Yiamouyiannis, 1993).
In 1953 Leo Spira had identified gingivitis and bleeding gums
as signs of chronic fluoride poisoning. In 1957 Ramseyer
observed gingivitis in older rats drinking water fluoridated at
1 ppm. By 1982 Domazalska observed a direct correlation between
the severity of periodontal disease and fluoride levels in
systemic fluids.

BIOCHEMISTRY
Background
As we have stated many times in the past, fluoride is known
as the “universal G protein activator” in biochemistry, meaning
it can activate all G protein families. The only known
receptor which is capable of doing the same, in the human
organism, is the receptor for the thyroid-stimulating-hormone
(TSH) (Gudermann et al, 1997).
This complex and multifunctional actvity of TSH is the
reason why so many
different diseases
are associated with thyroid hormone dysfunction. It is also the
reason why the same associations have been made in
fluoride poisoning
- fluoride being a TSH clone.
While for many years it was presumed that the TSH receptor
was only expressed in the thyroid gland itself, TSH receptors
have now been detected in liver, gastrointestinal tract
(Duntas et al, 1998), orbital tissue and dermal fibroblasts
(Paschke et al, 1994), peripheral lymphocytes, fat,
cardiac muscle (Drvota et al, 1995), thymus, peripheral
blood mononuclear cells, osteoblasts and osteosarcoma cells
(Inoue et al, 1998), or the brain - where it is
overexpressed in patients with
Down Syndrome
or Alzheimer's Disease (Labudova et al, 1999).
In order for us to understand fluoride poisoning better, we
have concentrated on the matter of Gq/11, as this is what TSH
does - at elevated levels it activates the Gq/11-mediated
pathways.
What are G q/11 proteins?
G q/11 proteins are membrane-associated proteins involved in
signal transduction - the way cells communicate with each other.
Gq/11 are coupled to receptors which cross the cell membrane
seven times ("transmembrane receptors"). Gq/11 proteins are
located in the membrane of a cell.
Upon receptor activation, they may send information directly
from the membrane to the cell's nucleus. Consider them an
essential "relay station" for cell information, the initiators
of other cascades of events. One such cascade involves the mitogen-activated-protein-kinase
(MAPK).
MAPKs are regarded as "switch" kinases in the phosphorylation
cascade.
Gq/11 may be released directly from the plasma membrane to an
intracellular location in response to activation by
aluminofluoride complexes [AlF(x)], directly translocating
immunoreactivity (i.e. Arthur et al, 1999).
Fluoride not only directly augments the already existing
hormonal (TSH) activation of Gq/11, it may activate such
proteins even in the absence of TSH. [Without TSH, G proteins
involved in thyroid hormone regulation are thought to be
inactive (Utiger, 1995).]
G q/11 Diseases
Gq/11-regulated pathways have profound effects not only on
the pathology of gum disease, but of chronic inflammation
overall, as well as cancer, heart disease, stroke, diabetes,
Alzheimer's Disease, Autism, etc. - in short - all those
conditions which represent the most significant health care
problems in the developed world today. We have come to describe
this as the “G q/11 disease”.
For example, in heart disease - which kills 725,192 people a
year in the U.S. alone, making it the #1 cause of death (CDC,
2002)
- it is G q/11 over-expression which leads to enlargement of the
heart, in turn leading to congestive heart failure. Therefore
recent pharmacological research has focused on creating
so-called "decoys" for G q/11 - non-working versions of Gq to
prevent the activation and reception of molecular signals that
normally would produce such enlargement of the heart (Akhter
et al, 1998; Adams et al, 2001).
It has been shown that on-going ("constitutive") G q/11
activation in heart muscle results in downsignalling of thyroid
hormone T3 and inhibition of T3-dependent intra-cellular
activities (i.e. Wu et al, 1997).
Needless to say, G q/11 are also involved in dental pulp and
enamel formation and are also involved in the condition known as
"dental fluorosis" (enamel hypoplasia) (Pozo et al, 2000;
Bawden et al, 1996). Gq/11 have been unequivocally
established to be the transducing G proteins for all
Ca(2+)-mobilizing receptors (i.e. Exton,1993).
In Alzheimer's and Down Syndrome patients Gq/11 is elevated
in the brain regions. Virtually all Down Syndrome patients
suffer from Alzheimer’s in their 40’s.
-
[NOTE: It is no coincidence that up to 90% of villagers
around the NALCO aluminum smelter in Angul, India are
experiencing "senility" before the age of 50 (Hindustan
Times, Aug. 15, 1999). In fact, Indian parliamentary
discussions disclose that, out of 14,000+ fluoride-poisoned
villagers in the area, 5,000 are suffering from Alzheimer’s
Disease (Lok Sabha Debates, 1999).]
Fluorides are most-established Gq/11 activators, ensuring a
firm and most-important rogue role for fluorides in all of the
above diseases. Both inorganic and organic fluoride compounds
may activate G q/11. It is a matter of degree in the
amplification of the F- signal.
Diseases linked to the pathways mediated by Gq/11:
-
Adenocarcinoma, leukemia, lymphoma, melanoma, myeloma,
sarcoma, teratocarcinoma, and cancers of the adrenal gland,
bladder, bone, brain, breast, cervix, gall bladder, ganglia,
gastrointestinal tract, heart, kidney, liver, lung, bone
marrow, muscle, ovary, pancreas, parathyroid, penis,
prostate, salivary glands, skin, spleen, testis, thymus,
thyroid, and uterus; and immune disorders such as AIDS,
Addison's disease, adult respiratory distress syndrome,
allergies, Alzheimer’s Disease, anemia, ASD, asthma,
atherosclerosis, bronchitis, cholecystitus, Crohn's disease,
ulcerative colitis, atopic dermatitis, dermatomyositis,
diabetes mellitus, emphysema, atrophic gastritis,
glomerulonephritis, gout, Graves' disease,
hypereosinophilia, irritable bowel syndrome, lupus
erythematosus, multiple sclerosis, myasthenia gravis,
myocardial or pericardial inflammation, osteoarthritis,
osteoporosis, pancreatitis, polymyositis, rheumatoid
arthritis, scleroderma, Sjogren's syndrome, thyroiditis,
etc..
As fluoride mimics TSH, we usually check on
Down Syndrome
first - as all DS patients have shown to have higher TSH levels,
they will often show us what fluoride poisoning does. As TSH
activates G q/11 - to which PGE2 and TXA 2 are coupled - similar
oral conditions should be observable in DS. Needless to say, DS
patients also have a high degree of periodontal disease
(Decoq, 1995;Wilkins, 1994; Ulseth et al, 1991; Barnett et al,
1986).
Gq/11 and the ras oncogene share in mediation of
pathways, including
MAPK
(i.e. LaMorte et al, 1994; Seo et al, 2000).
Oral Cancer - The ras oncogene
Biochemical research in the “search for cancer” conducted
during the last few decades has firmly established the
involvement of mutated G proteins in the pathogenesis of cancer,
including oral cancer (Das et al, 2000; Yoo et al, 2000).
One such well-known mutated G protein is the "ras"
oncogene.
These ras oncogenes were first found in human bladder
cancer cells, and have now been identified further in pancreas,
breast, prostate, thyroid, lung, and uterine cancers, myeloid
leukeamias, etc. as well as skin and oral cancers.
Among the cancers which most often include mutated ras
genes are adenocarcinomas of the pancreas (90%) (Almoguera et
al., 1988), adenocarcinomas of the colon and cancers of the
thyroid (50%), as well as carcinomas of the lung and myeloid
leukeamias (Bos,1989).
During the last 10 years frantic research has been conducted
by the pharmaceutical companies directed at finding agents to
counteract ras activity.
In efforts to define the very pathways of ras in
cancers - so that treatments can be developed - biochemists have
used sodium fluoride or aluminum fluoride extensively in the
past, at many different levels, and under various conditions.
This is because fluoride can substitute directly for the
ras oncogene, and at levels even below those seen in the
Sepracor patent investigations, especially when
combined with aluminum.
ras oncogene pathways are readily activated by
aluminum-fluoride complexes [(AlF(x)] (i.e. Warner et al,
1999; Kleuss et al, 1994; Camp et al, 1993; Matyas et al,
1989; O'Shea etal, 1987; Spina et al, 1987; Haliotis et al,
1988;Lee et al, 1992), as well as beryllium fluoride
compounds (Diaz et al, 2000, 1997; Kuppens et al, 1999).
The activation of some mutations is more pronounced or
"amplified" by aluminum fluorides (Warner et al, 1999a,b)
while others simply prefer the "false" AlF(x) activation
(Natochin et al, 1999; Warner et al, 1999; Clabecq et al,
2000).
For some, the AlF4--induced activation defect is more
pronounced at low magnesium (Mg2+) concentrations (Warner et
al, 1999).

Additional Comments
Aluminum Fluoride
Although the "patent" scientists cite a paper by Kawase et
al (1991) which documents the potentiating power of the
mere trace amounts of aluminum upon sodium fluoride activation
on prostaglandin receptors - in their own calculation with
sodium fluoride they fail to account for this important fact.
Potentiating effects of aluminum might well exceed 500%, making
the fluoride concentrations required for prostaglandin
activation much lower than those observed in the patent (see:
Imai et al., 1996; Turinsky et al, 1992; Kawase et al, 1989).
Already in 1989 Kawase et al had shown in
HL-60
cells - the cells used in the patent investigation - that in the
presence of mere trace amounts of aluminum, NaF concentrations
ranging from 0.01 to 1 mM increased PGE2 synthesis in a
dose-dependent manner, whereas NaF alone at lower concentrations
(below 0.1 mM) did not show such a significant effect.
Further, when Kawase investigated
HL-60
cells treated with sodium fluoride only, he had many more
additional findings to report: not only did sodium fluoride
increase prostaglandin E2 production, but NaF- produced marked
changes in cellular morphology, increased cellular adhesion to
plastic, reduced the nuclear/cytoplasmic ratio, increased
cellular expression of chloroacetate esterase, and stimulated
production of interleukin 1 alpha (IL-1 alpha), IL-6, and the
tumor necrosis factors (Kawase, 1989).
“White Spots” - Candidiasis
As mentioned above, the “white spots” in the mouths of our
kids were also frequently attributed to candidiasis (yeast
infection) by medical professionals.
Candidiasis is an infection of the moist cutaneous areas of
the body, and is generally caused by the fungus Candida
albicans. It involves the skin, oral mucous membranes,
respiratory tract and vagina.
In workers exposed to fluorides, Candida albicans was
seen in 73.7% of cases. 80% of the cases showed a considerable
intensification of periodonatal diseases. Leukoplakia
[pre-cancerous growth] and candidiasis were the most
common changes found (Ilewicz et al, 1982).
Other studies on workers have since confirmed those findings
(Borysewicz-Lewicka, 1983; Sroczynski et al, 1991). Case
reports on candidiasis caused by fluoride mouthrinse are
also known (i.e. Axell & Edwarsson, 1978). [see:Part

THYROID - GINGIVITIS
Of course many of us who suffer from hypothyroidism and are
on replacement thyroid hormone know about gingivitis and
periodontal disease, a quite common concern.
During the last 40 years the strong association between
periodontal disease and thyroid disorders, especially
hypothyroidism has been documented many times over in the world
literature (i.e. Riedel & Ordelheide, 1966; Abate, 1968; Baba
et al, 1972; Pencea et al, 1978; Saburova & Isaeva, 1971;
Schneider, 1969; Shkoliar et al,1967; Pashaev, 1982; Danilevskii
et al, 1988; Kerimov, 1989; Puzin et al, 1996, etc).
Yet it has received little or no attention in the US.
In women with general periodontitis all hormonal systems were
shown to be excessively shifted (Puzin et al, 1996).
Wendy Small compiled the following “anecdotal evidence” from
past newsgroup/e-mail postings:
1) "The pockets around my gums started getting deeper & the
dentist had me coming in every 3 months, instead of the usual 6
months. The pockets got so bad I had to have scaling of one
area. On my last visit there was a huge difference. I noticed at
this time my TSH was 1.3, so I really think our thyroid level
effect this. I go back in May & my TSH has increased slightly,
hopefully not enough to increase the pocket size again."
#2) "My own periodontal issues did not begin to resolve until
after probably six months of thyroid treatment ...My own
periodontist had no clue about the connection between
hypothyroid and beginning- or worsening- gum disease, until he
saw my own problems stabilize and then begin to heal after a few
months of thyroid meds. Prior to my dx of hypo I had been
receiving treatment for periodontal disease for a couple of
years, and it was just getting worse, little by little - never
improved one bit until thyroid supplementation began..."
3) "Monday I went to the dentist for a routine cleaning. I had
noticed for about a week or two that my gums were sensitive and
bleed some when I brush, but nothing really bad. Or so I
thought. The first thing the hygienist did was a periodontal
measuring (don't know the official name for what she did) but it
consisted of taking a very thin pick with measurement marks on
it and inserting between my gums and teeth. She did this at a
couple of different places on each tooth and noted the numbers.
This is supposed to tell them if I have signs of gingivitis or
periodontal disease. Anyway, the point of all of this is that
by the time she had done all my teeth my mouth was bleeding so
bad she wouldn't finish the cleaning. All she did was a
treatment with some sort of antibacterial solution (felt like
she used a water-pik) and sent me home with some medicine to
rinse with. I go back in a few weeks for a recheck and a
cleaning. I asked my doctor if it was related and he said he
didn't think so, but I was just wondering if anyone else has had
similar problems."
