Peanuts and other dangers
Amongst the population there are some, the exact numbers
are not known, but it is probably within the range of 1-2%,
who react strongly to a number of common conditions. These
include light, high temperatures, and a vast number of natural
and synthetic substances, including insect stings, contact
with certain toxic plants, common foodstuffs and drugs,
such as penicillin.
A young Scottish athlete died because he ingested a very
small quantity of peanuts in a chicken sandwich. He made
a mistake in not reading the contents of his sandwich, and
although extremely fit (in an athletic sense) he died very
quickly. Deaths from eating peanuts, or from being prescribed
penicillin are not rare5. There were six peanut
fatalities in Great Britain in 1993. Other literature shows
that peanut allergy is a widespread, serious problem6-8.
Being a natural product may be dangerous: many die from
consuming wild mushrooms, or from contact with plants which
contain defence mechanisms. Nevertheless, people are also
allergic to many man-made substances, including many fabrics
and PVC.
Like many human conditions there is a continuum from those
whose bodies are relatively insensitive to a wide range
of conditions to those who are ultra-sensitive and who may
have to avoid exposure to strong sunlight for even quite
short periods. The symptoms ascribed to latex protein allergy
may be traceable to a wide range of foods or contact with
other materials.
Only tests will show if a patient who thinks he is allergic
to latex proteins is potentially at risk, although there
is a relatively high probability that such an allergic person
may have had this alleged allergy triggered by something
else. There is a growing literature concerning those who
experience "cross allergies" with an equally expanding
range of foods, clothing and other materials. These people
are [unfairly] tagged as being sufferers of latex protein
allergy, whereas they may in fact be sufferers of peanut,
cornstarch, or a vast range of foods, allergies.
There is a high probability9 that those who
are liable to suffer from latex protein allergy are atopic,
that is they are predisposed to allergic responses to a
range of materials. In an in-depth study it was found that
sufferers tended to have a history of skin allergies and
to have a history of skin damage in the form of several
symptoms. Latex may not have triggered their allergic reactions:
cornstarch may be far more important as the vector than
has been given credence. Thus it is never entirely clear
that latex protein allergy has been the trigger for some
allergic reaction, rather than a common food, such as bananas.
When discussing allergic reactions to foodstuffs it is
important to distinguish between those who think that they
are allergic to some item of food and those who are actually
allergic, as indicated by clinical tests10-11.
Between 10% and 20% of the population12 consider
themselves to be allergic to foods, but clinical tests reduce
the actual occurrence to about 2%.
Furthermore, both those who think that they, and actually
are, tend to be female and/or young. It would seem to be
highly probable that a similar ratio may exist with "allergic
reactions" to latex goods. The peculiar nature of the
American medical profession (claims of up to 17% having
the "potential" to be allergic) towards latex
gloves would appear to be widely at variance with "normal"
allergic behaviour. Certainly, there is a preponderance
of female sufferers. This may be because more females wear
gloves, or because females are more prone to detecting allergic
reactions: western women tend to be extremely "skin
conscious".
There is a further factor which does not appear to have
been considered, namely the wearing of a restrictive material
over extended periods. It is probable that the fear of AIDS
led medical workers to wear gloves for protracted periods
without cause in case they needed to handle a patient rather
than donning gloves for specific tasks. Unfortunately, there
does not appear to be any literature on this, although there
are references to the risks of wearing general protective
clothing for long periods in relation to increased body
temperatures. Presumably extensive donning must also tend
to damage the skin.
