When an illness or infection attacks us, the first thing that comes to mind is to fight it with antibiotics, which are responsible for wiping out all bacteria and viruses that have caused the damage.

Many have heard that overuse of antibiotics can lead to problems Gastric the nature of its components, which is quite true, why is suggested that these not be taken without having taken some food to avoid causing damage to the stomach. But that’s not all, because the damage caused by antibiotics beyond that.

First, because the excess in the administration of antibiotics will get them to develop resistance to these, when required for some other time, bacteria and microorganisms that attack us, they will be better prepared to support the battle against antibiotics. And this only happen if we provide large quantities of it to get used and then not get the effects we want.

Allergy, rather than a disease, is determined as the body’s hypersensitivity to a substance or item that when touched, ingested or smell triggers certain characteristic symptoms.

The word allergy comes from the Greek allergies?, And this in turn all voices, another and ergs, work, giving the meaning of “strange reaction,” the allergy is caused by certain elements called allergens and the symptoms produced are called allergic reactions.

When faced with a body allergic to the allergenic substance, and is constant exposure to it, the immune system generates an antibody response by releasing substances such as histamine, which produce symptoms in the subject themselves of an allergic reaction.
Types of allergy
Scientific classification

They have failed to identify and describe four types of hypersensitivity reactions or allergies. The four basic types are based on the classification of Coombs and Gell, 1963 are: Read the rest of this entry »

In respiratory allergy (rhinitis, asthma) and allergy to wasp or bee, you can use Immunotherapy (also called allergy vaccine or hyposensitization), which is a treatment that involves injecting a purified extract of allergens to the patient, that is injected subcutaneously the substance to which the patient is allergic, increasing the dose slowly to the body to be accustomed or become “tolerant” to the allergen gradually. It must make him or the major allergens, discarding the secondary or unimportant . In Europe not allowed to mix different kinds of allergens (eg pollen should not be mixed with mites or fungal or animal with each other) and should not be administered over three different allergens at a time (more than 3 pollen types at once, for example) in America are still other rules and still supported the mixture of allergenic extracts to be administered in addition (in Europe and alergoides depot extracts). There are several types of immunotherapy or allergy shots, are usually given initially on a weekly or several days after reaching the maintenance dose, is held monthly (or weekly in America), necessitating the vaccine is usually done for 3 -5 years since its curative effect is slow and progressive.

Only 5% of allergic patients following the previous treatment because of its duration and risk. For this, a research team in Switzerland, tested the effectiveness and the risk associated with injecting the allergen into the lymph nodes rather than injected subcutaneously. They concluded that this new treatment improved the safety and efficacy and reduced the processing time to eight weeks. As a bonus, the injected dose was much lower (a thousand times) than that used in a subcutaneous treatment.

There are oral vaccines now in Europe (sublingual) have not yet approved in the U.S. and still very controversial. These allergen extracts or vaccines contain no allergy medication such as antihistamines or corticosteroids. This treatment can range between 3 and 5 years. These vaccines, placed improperly, can cause anaphylaxis (also called anaphylactic shock). There are still unverified rumors about people because of these vaccines have gone into a coma and even death have suffered.

The allergy is very important to take avoidance measures (prophylaxis) of the allergen when it is avoidable.

In urban areas allergens abound: smog, micromohos, pollens, mites (mites are infesting mattresses and especially carpets), the pet hair can also be a carrier of allergens, such as the cat to lick his saliva leaves his hair, the saliva dries in flakes fly through the air and can cause allergy-prone people.
Cleaning, avoid high humidity environments are enclosed or prophylactic habits, is also sufficient prophylactic vaccination against specific allergens in allergic individuals.
It should be noted that the seasonal change going from summer to fall, with sudden cooling, increases susceptibility to various insults (among Read the rest of this entry »

Types of allergy, according to the source of the allergen.

• Food allergy
• Allergy to pollen (hay fever, archaically “hay fever”)
• Allergy to dust mites
• Allergy to the bites of certain insects (eg bees)
• Allergies to animals

Allergy to metals

The most common allergy that can be cited among such is allergy to nickel, which is present in virtually all alloys of non-noble metals and sometimes in some low-gold alloys.

Nickel allergy is mediated by a type I hypersensitivity mechanism 4 with inflammation caused by direct mediator release by lymphocytes. The most common symptoms are the production of eczema in the area of contact with metals (jewelry, metal closures underwear, etc.)

The best defense is avoiding contact with these metals, and once appeared, with corticosteroids (steroids) applied locally in the short term. Although allergy symptoms go away and look forward, the nature of awareness is chronic, with periods of greater or less tolerance.

Severe allergic crises may be accompanied by:

• Anaphylactic shock: acute and severe allergic reaction that can be lethal.
• Quincke’s edema or angioedema.
• Dizziness, fainting, dizziness, nausea
• Swelling of the lips, eyelids, fingers, itching or tingling in the body.
• Shortness of breath (dyspnea).
• Discomfort or decay.
• Urticaria (usually provocadada bites, medications, latex .)
• Sneezing: allergic rhinitis (or “hay fever”).

Allergies being an abnormal response of the immune system is considered that potential exists in four aspects:

• Immediate: Depending on the aforementioned antibody type E (IgE) (in urticaria and Quincke’s edema).
• Cytotoxic: With the antibodies of the IgG.
• Immune complex: IgG but also linked to form complexes immunes
• Delayed: Linked to cellular inflammation as is the responsible allergy eczema.

The substance you are allergic is called “allergen“, and the symptoms caused are defined as “allergic reactions”. When an allergen enters the body of a subject allergic, it’s immune system responds by producing large numbers of antibodies called IgE. The subsequent exposure to the allergen will result in the release of chemical mediators, including histamine, which produce the typical symptoms of allergic reaction.

Pirquet in 1905 suggests that serum sickness (a phenomenon of hypersensitivity) is directly related to the production of antibodies or antigens against serum injected, introducing the term allergy to describe the altered immune reactivity in which usually presents a strong release of histamine.
