	Allergic reactions (Site not responding. Last check: 2007-11-06)
		Anaphylaxis is a sudden and severe allergic reaction that occurs within minutes of exposure, PROGRESSES RAPIDLY and can lead to anaphylactic shock and death within 15 minutes if medical intervention is not obtained.
		If the allergic reaction is from a honey bee sting, scrape the stinger off the skin with something firm (such as a fingernail or plastic credit card).

		Some of these reactions are the result of an allergic reaction that involves the immune system, but many are the result of a non-allergic, or irritant, reaction.
		The hallmark of allergic contact dermatitis is that it occurs almost exclusively where the offending agent-such as a plant or chemical-comes in contact with the skin.
		Allergic contact dermatitis is best exemplified by the itchy, red, blistered reaction that almost everyone experiences after touching a plant in the "rhus" family-poison ivy, poison oak or poison sumac.

		Allergic rhinitis is characterized by congestion, itching and dripping of the nose and itchy, watery eyes.
		Allergic rhinitis is considered a risk factor in developing asthma: up to 78% of those with asthma also have allergic rhinitis.
		In summary, an allergic reaction is a complex chain of events that involves many cells, chemicals and tissues throughout the body.

		Overall, allergic diseases are among the major causes of illness and disability in the United States, affecting as many as 40 to 50 million Americans.
		This booklet summarizes what is known about the causes and symptoms of allergic reactions to airborne allergens, how these reactions are diagnosed and treated, and what medical researchers are doing to help people who suffer from these allergies.
		For example, people allergic to ragweed may leave their ragweed-ridden communities and relocate to areas where ragweed does not grow, only to develop allergies to other weeds or even to grasses or trees in their new surroundings.

	Allergic Reactions - TheHorse.com
		Allergic reactions are complicated and somewhat unpredictable events that are triggered by various environmental factors or other physiologic abnormalities.
		The major basis for many of the allergic reactions is the release of a variety of chemicals from either the eosinophil or mast cell.
		In routine allergic reactions, once the allergen enters the body it is recognized by the IgE protein molecule, which then binds to the allergen.

	Bee Stings and "Allergic" Reactions
		There is agreement that a local reaction is generally characterized by: pain, swelling, redness, itching and a wheal surrounding the wound made by the stinging apparatus.
		This is the reaction of the vast majority of persons and those suffering it are considered to be at little risk of death, unless the mouth or throat is affected so that the respiratory tract is obstructed.
		Another study revealed that prevalence of sustained systemic reactions was no greater in an allergic population than the population at large, again not referring to those experienced as life-threatening or anaphylactic, and further arguing against an allergic basis.

	US FDA/CFSAN - Food Allergies Rare but Risky (Site not responding. Last check: 2007-11-06)
		Like less serious allergic reactions, anaphylaxis usually occurs after a person is exposed to an allergen to which he or she was sensitized by previous exposure (that is, it does not usually occur the first time a person eats a particular food).
		Asthma, a disease with allergic underpinnings, was common to all children in the study.
		Children who have an allergic reaction should be observed for three to four hours after a reaction in a medical center capable of dealing with anaphylaxis.

		A person who has experienced even mild allergic reactions to food should seek a professional diagnosis by a board-certified allergist (see Find an Allergist to locate an allergist near you).
		Therefore, it is essential that people with food allergies protect themselves by carefully avoiding the foods that trigger their reactions, and by being prepared to treat anaphylactic reactions that occur immediately with epinephrine in combination with emergency medical care.
		The treatment of choice for severe allergic reactions to food, which can swiftly lead to anaphylaxis, is an immediate injection of epinephrine followed by emergency medical attention.

		Allergic reactions are sensitivities to a specific substance, called an allergen, that is contacted through the skin, inhaled into the lungs, swallowed, or injected.
		In fact, the immune response that causes an allergic reaction is similar to that which causes hayfever.
		Many allergic reactions are mild and can be treated at home, while others can be severe and life-threatening.

		Or, you might find that it took years in a pollen-heavy environment (such as a valley in which the main industry is grass-seed farming), to gradually develop a reaction of increasig severity to that pollen.
		Atopic diseases are distinguished by their tendency to produce allergic reactions to normally harmless inhalants and other substances, such as pollens, molds, animal dander, dust mites, and nuts.

	Allergic Reactions
		Allergic reactions are highly individual inflammatory responses against specific proteins entering the body.
		Medications can be used to "head off" allergic reactions before they happen and with the use of these medications it is possible that a reacting pet can be vaccinated normally.
		Vaccination reactions severe enough to produce shock are EXTREMELY rare and are a function of an individual pet's immune response.

	Fatal anaphylactic reactions to food in children
		For any acute reaction to food a description of the symptoms and signs and of all foods eaten before the reaction, including manufacturer and lot number of processed foods, recipe ingredients and all other relevant information, should be obtained.
		Children at risk of lethal allergic reactions to food must not eat food given to them by other children or by adults other than their parents or caregivers.
		An anaphylactic reaction generally follows one of three patterns: rapid progression (uniphasic), protracted symptoms (uniphasic) or initial symptoms followed by a relatively symptom-free period of up to 2 hours and then by respiratory symptoms or hypotension or both (biphasic).
