Title: Allergy Awareness


1
Allergy Awareness
2
What is an Allergy ?
  • An allergy is a condition of unusual
    sensitivity which certain individuals may
    develop to substances ordinarily harmless.

3
Sensitizing substances are called allergens.
4
Common allergens include pollens, molds, house
dust, animal dander, bee venom, antibiotics and
other medications, nuts, peanuts, milk, and
shellfish.
5
Others you may not think of include feathers,
chemicals in cosmetics, wood, dyes, perfumes,
metal (such as nickel), eggs, wheat, heat, cold,
sunlight, and even exercise!
6
Allergens may be taken into the body by being
swallowed
  • (such as nuts, peanuts, or shellfish)

7
being injected,
  • (such as bee venom)

8
contact on the skin,
  • (such as poison ivy or latex)

9
inhalation,
  • (such as when poison ivy is burned or latex
    particles become airborne)

10
or bacterial infection in the body.
11
What happens within the body to cause an allergic
reaction?
12
When an allergen is taken into the body, the body
produces antibodies which react to recognize and
attack it. That is why sensitivity often does not
happen with the first contact. It may take
several exposures for the reaction to occur.
13
The antibodies (specifically antibodies called
IgE) attach to mast cells throughout the body.
These mast cells release histamines that produce
a reaction in sensitive tissues such as eye,
nose, skin, respiratory track, digestive track,
and cardiovascular system.
14
Who is most likely to develop an allergy?
15
An allergy can develop at any age from birth to
death. Children aged 5 to 15 are more apt to
develop allergies than older individuals, yet
people of any age may experience their first
allergy attackafter having lived allergy-free
for years.
16
There is a hereditary component to allergic
tendency, but anyone can develop an allergy.
17
The 5 most common food allergies in children are
  • Milk
  • Eggs
  • Peanuts (including products made with peanut
    oil)
  • Tree Nuts ( such as walnuts, cashews, pecans,
    etc.)
  • Wheat
  • Soy

18
Treatment for Allergies
  • 1. Removal of the allergen, if possible.
  • 2. Medication such as antihistamines,
    epinephrine, and others.
  • 3 In some cases, patients opt for
    desensitization injections

19
With desensitization injections, a tiny amount of
the allergen is injected under the skin and is
gradually increased over time so that the body
can build up resistance. This causes the body to
increase production of a different type of
antibody called IgG, which recognizes the
allergen but doesnt attach to histamine
releasing mast cells.
20
People working in a school district may have
responsibility for individuals who have
potentially life threatening allergies, so it is
important to know how to recognize and manage a
serious allergic reaction.
21
What is anaphylaxis or an anaphylactic reaction?
  • It is a sudden, severe, allergic reaction that
    involves various systems of the body
    simultaneously.
  • It is a true, life-threatening emergency!

22
An anaphylactic reaction, if not treated, can
quickly lead to anaphylactic shock. When this
happens, exposure to the allergen makes blood
vessels dilate which rapidly causes a severe drop
in blood pressure.
23
It is important to recognize and act quickly
during an anaphylactic emergency because the
reaction may advance rapidly to respiratory
failure, cardio-vascular shock, and sudden death.
24
School district employees such as teachers, bus
drivers, and others may be in situations where
they will be expected to recognize a severe
allergic reaction and deliver emergency treatment
in the form of an epi-pen or other prescribed
medication.
25
A school district employee, or any person, for
that matter, is legally covered under the Good
Samaritan Law for assisting a victim in an
emergency situation.
26
In fact, a person who would fail to assist might
be considered negligent. In any event, the
consequences of not administering an Epi-pen (or
other prescribed medication) to an individual
experiencing a life-threatening allergic reaction
are unthinkable.
