Diabetes, in turn, is known to increase the risk for periodontal disease.

How could this be happening?
Every second felt like an hour. She was still coughing and
wheezing, and that was a good sign. If she stopped, it meant
her airway was completely closed. Even though she couldn’t
breathe, she still didn’t want me to call 911, but of course I did.
We were eating and talking one moment; she jumped up and
was gone the next. All of my training in CPR wouldn’t make
much difference if her airway closed completely. Hopefully the
epinephrine and Benadryl would help keep her airway partially
open until more help arrived. Did I start hyperventilating myself?
No, I knew what to do. I realize now that staying current in
my first aid training, not just the required CPR, could mean the
difference between life and death. I know after this experience
that I am going to do everything I can to help more people,
particularly oral health professionals, realize that this scenario
could happen to them.

the gold standard for diagnosis of food allergies.
• Food allergy can be treated by desensitization shots or
drops. This is unfortunately not the case. The only treatment is
to completely avoid the problem food.
• Food allergy is rarely life-threatening. False. Food allergy
remains a major cause of anaphylaxis treated in emergency
rooms.
Though there are a number of promising therapeutic modalities being researched, the only proven therapy for food allergies is avoidance. This includes reading labels, avoiding high-risk
situations such as buffets, and asking about ingredients. Some
people think that picking an offending item out of a dish makes
a food safe. This is incorrect. For someone like my sister, removing a crouton from a salad still puts her at high risk for a reaction. Reactions can occur from aerosolized food protein in the
steam of cooking the food, particularly boiling seafood.
Not all reactions to food are a direct allergy to that food. An
oral allergy syndrome may bring on sensitivity to foods in the
same classification, in a cross-reaction manner. This can
occur in a person with no known food allergies. A person
with a ragweed allergy might react to fresh melons and
bananas. People with grass pollen allergy might develop
symptoms after eating raw tomatoes. A person allergic
to birch pollen might react after eating raw potatoes, carrots, celery, apples, pears, hazelnuts, or kiwi.
The Food Allergen Labeling and Consumer Protection
Act (FALCPA) became effective in January 2006. It ensures
that people can easily and accurately identify ingredients
that may cause a reaction. Under this law, allergen declarations must be in plain English. Though more than 160
foods have been identified as triggering food allergies,
this law is limited to the eight major food allergens which
account for 90 percent of food allergies in the United
States. These are milk, eggs, fish (e.g., bass, flounder,
cod), crustacean shellfish (e.g., crab, lobster, shrimp), tree
nuts (e.g., almonds, pecans, walnuts), wheat, peanuts,
soybeans, or any ingredient that contains a protein derived from one of these foods.
While some allergic reactions to food are mild, foodallergic individuals can experience severe reactions.
Generalized anaphylaxis caused by food allergies accounts
for at least one-third to one-half of the anaphylaxis cases
seen in hospital emergency departments. Anaphylaxis is
the dramatic multi-organ reaction associated with IgEmediated hypersensitivity. Fatal food-related anaphylaxis
appears to be more common in patients with underlying asthma. Symptoms usually appear rapidly, sometimes
within minutes of exposure. Immediate medical attention
is necessary.
Epinephrine has long been the treatment of choice
for acute anaphylaxis. Even when epinephrine is used
promptly, it is not always effective in severe cases. People
with diagnosed food allergies should have epinephrine
prescribed and carry it with them at all times. They should
also wear an identification bracelet describing the allergy.
Oral health professionals need to be aware of the location and
use of the patient’s epinephrine, and that it must be given intermuscularly, not intravenously or subcutaneously.
The American Academy of Allergy, Asthma, and Immunology’s
The Use of Epinephrine advocacy statement says: “Epinephrine
must also be available in many first aid situations for use by
trained personnel who can evaluate the scene, the indication,
benefit, and risk of treatment with epinephrine in individual
cases. These efforts could significantly reduce the annual death
rate associated with sting and food anaphylaxis.”
This statement emphasized the need for personnel trained in
first aid. Most practice acts require hygienists to maintain current CPR certification. CPR certification courses are not the same
as and do not always include first aid training. In November
2005, the American Heart Association (AHA) and the American
Red Cross (ARC) came together to review the scientific literature
and publish the 2005 Guidelines for First Aid, which updated

Anaphylaxis = Killer Allergy*
Who is at risk?
Anyone, especially those allergic to foods such
as peanut, tree nut, seafood, fin fish, milk, egg, and
wheat, or to insect stings or bites, natural rubber latex,
or medications.
When can it happen?
Within minutes, anytime the allergic person comes
in contact with his or her trigger.
How do we know?
Several symptoms occur at the same tie, such as
itching, hives, flushing, difficulty breathing, vomiting,
diarrhea, dizziness, confusion, and shock.
Where can it happen?
Anywhere — home, restaurant, school, child care,
sports facility, summer camp, car, bus, airplane, or
dental office.
What should we do?
Inject epinephrine, call 911 or your local emergency
number, and notify the individual’s family — in that
order. Act quickly. Anaphylaxis can be mild or fatal.

the previous guidelines. (Note: These first aid guidelines are in
addition to the 2005 AHA guidelines for CPR.) Topics that are
new to the 2005 guidelines include use of oxygen, use of inhalers, use of epinephrine auto-injectors, wounds and abrasions,
dental injuries, snakebites, and cold emergencies. These were
added to the coursework on seizures, bleeding, burns, musculoskeletal trauma, and poisoning.
An Internet search on dentistry and allergy lists numerous hits
on latex sensitivity and reactions to dental anesthetics. Though
latex and anesthetic sensitivity are important, they are not the
only situations in which an allergic reaction can occur. Could
a food allergic reaction or anaphylaxis occur in the dental office? Possibly, because dental health professionals often do not
know what the products they use contain. Even trace amounts
of seemingly innocuous ingredients could put someone at risk.
Unless we have a full understanding of the life-threatening pos-
sibilities of allergy, early symptoms might not be recognized.
Every dental health professional should enroll in a first aid training course, as well as maintain CPR certification.
It is my hope that with the research on promising therapeutic
modalities, improved product labeling, and training in first aid
along with a heightened awareness, my sister and others can
rest better knowing that help will be there when they need it,
particularly from their oral health providers.
Epilogue: It took several hours and multiple medications at
the hospital to stabilize my sister. It took another several months
to get her system back on track. Unfortunately, she has had
more reactions that have sent her the hospital. She has committed to a campaign to increase public and professional awareness. RDH
