To diagnose allergies the patient may be subjected to one or more of the following clinical studies:

Measurement of immunoglobulin E. Blood test that reveals the total amount of the antibody in the body when in contact with an allergen.

Skin tests. Consist of applying in the forearm or back different substances that can cause allergy, such as dust, mold, pollen, animal hair, cosmetics, metals, food and medicine. Those affected by this disease have redness, hives and itching 15 minutes later.

Patch testing. When practicing different substances are placed on the skin of the back, which are covered with patches for 48 or 72 hours later, we review in which regions of the epidermis was allergic response.

Antihistamines when administering

Antihistamines are of great help in controlling allergic type diseases, such as:

Angioedema. Inflammation and fluid accumulation in the deeper layers of the skin, especially as part of hands, feet and face, although it may occur in the throat and difficulty breathing or swallowing ability. Its appearance is associated with the ingestion of certain foods and medications that are not well tolerated by the body.

Asthma. Chronic disease that clogs the respiratory tract because it inflames the tubes that carry air to the lungs, usually manifests itself by presenting an exaggerated sensitivity to irritants such as pollen, smoke, dust, certain products or animal hair.

Conjunctivitis. Swelling and redness of the conjunctiva (the membrane located between the eye and inner eyelid, which is responsible for maintaining the required humidity), characterized by causing discharge, burning, irritation and tearing.

Dermatitis. Skin inflammation that occurs when the tissue comes into contact with irritating substances contained in plants, cosmetics, detergents, synthetic fibers, metal jewelry, insect bites, and by the action of any medicine or food. Cause characterized by redness, blisters, dryness, flaking and itching difficult to control.

Allergic rhinitis. Inflammation of the lining of the nose that causes dripping, itching, sneezing, runny nose, stuffy ears, diminished sense of smell, headache and fatigue, occurs when inhaled environmental pollutants, pollen, or is in contact with animals.

Urticaria. Eruption of hives all over the skin accompanied by intense itching and swelling occurs when skin is exposed to irritants, metals and some plants, or by eating food or medicine to which sensitivity has been developed.

A team from the Finnish Institute of Occupational Health was obtained for the first time, consistent evidence indicating that snuff itself can cause asthma.

The results of the study, published in ‘European Respiratory Journal, show that both smokers and former smokers are more likely to be asthmatic than those who never had the habit, indicating that the effects of nicotine on the body remain over time. In fact, even former smokers have higher risk of contracting the disease (49%) than those who continue to smoke (33%).

But the worst part is worn by women. According to the authors of the study the risk of developing asthma than females can become 143%. For Dr. Ritva Piipari, one of the researchers, this may be because “women are much more vulnerable to the harmful effects of substances from cigarettes than men.

One theory is supported by the fact that even non-smokers are more likely to be asthmatic (57%) than men who have also stopped smoking.

Another important findings of this work is that the risk of developing asthma is proportional to the number of cigarettes smoked per day and the total amount smoked throughout life.

Research

In reaching this conclusion, the Finnish Institute team studied a group of 1,444 people, including smokers and nonsmokers, in southern Finland during a period of two years.

In addition to several questionnaires, participants completed tests that measured their lung function and needed to establish their own symptoms of asthma. Individuals who already were asthmatics, who had chronic bronchitis or emphysema who had suffered lung were excluded.

But the greatest risk of asthma has been discovered in this work does not apply to heavy smokers, those smoking more than 15 cigarettes per day or who smoked heavily throughout her life.

Researchers believe that this fact, qualifying surprising, could be explained “if one considers that these heavy smokers sooner they quit, as they feel any kind of respiratory problems, before they can diagnose asthma.”

Also, note that each person differently tolerant components and snuff could be that smokers over 15 cigarettes daily irritant better bear in cigarettes.
