allergies: pollen, dust mites, the warm weather arrives mascotasCuando allergic processes multiply. Allergies are extremely annoying stationary but these are simply inflammatory reactions of the upper airway hypersensitivity response.

This reaction occurs when there is contact with many substances that are present in the air we breathe. At the time of the spring bloom occurs in various plant species such as olives, bananas, grasses, etc. Cupressaceae. a high concentration of pollen.

Seasonal rhinitis occurs suddenly when the ambient level of pollen increases rapidly. This occurs in the months of May and July as the wind increases and expands the pollen as soon as it rains, the atmosphere is clean and decreases the amount of pollen in the air.

Seasonal allergy symptoms

Allergens cause an inflammatory reaction and cause dilation of blood vessels in the nasal membranes. This reaction leads to the following characteristic symptoms: continuous sneezing, nasal congestion, nasal and pharyngeal tingling, production of mucus, headache, earache and irritation of the eyes.

The processes are manifested as allergic conjunctivitis, asthma, urticaria, anaphylaxis, rhinitis or urticaria. Sometimes allergic processes occur seasonally and others have throughout the year due to frequent exposure to triggers.

The diagnosis of allergy requires a personal observation and immunological studies in which the patient underwent skin tests for exposure to the allergen extracts and substances that are supposed to be suspicious.

By obtaining a conclusive result, treatment is started immunotherapy with extracts extremely sensitizing increasingly administered under the skin or mouth, or making a drug treatment for the symptoms with steroids, bronchodilators, antihistamines and decongestants.

Apart from pollen, mold spores, mold, mites and dander remains of domestic animals also cause allergies.

Allergic conditions caused by the spores increase during wet weather, spider mites are a microscopic feed on human skin flakes and animal and can be found in blankets, mattresses or sofas.

The hair and dander of pets especially cats are potent allergens. Environment pollution, exposure to fumes from exhaust pipes, snuff and smoke also can lead to allergic reactions like.

Giving children with milk allergies increasingly higher doses of milk may ease, and even help them completely overcome, their allergic reactions, according to the results of a study conducted by Johns Hopkins Children’s Center, conducted jointly with Duke University commented on todoalergias.com.

Despite the small number of patients in the study, 19 the results are encouraging and enlightening, the researchers say, because this is the first study of immunotherapy to milk the system by double-blind, placebo-controlled. In the study, researchers compared a group of children receiving milk powder with a group of children who received placebo, identical in appearance and the real flavor of milk powder. Neither the patients nor the investigators knew which child received each of these powders, a rigorous research setup that minimizes the possibility of error and bias.

The findings were presented on the Internet, before they appear in the Journal of Allergy & Clinical Immunology. Read the rest of this entry »

Will I recognize the symptoms? What should I do if they occur? Do I need to remove food from my milk? Here are solutions to your questions about food allergy.

1. What foods cause allergies?

In principle, all foods contain antigens capable of causing allergy. These antigens are proteins that the immune system of an atopic person considered “strange” and, therefore, is the need to defend themselves. What determines that some of these allergic reactions occur more easily than others has everything to do with our eating habits: thus, for example, in our country children are sensitized mainly to egg and milk, consumed food items and is introduced into the diet in the first two years of life, which is also when there are more cases of sensitization. Allergy to fish, legumes and nuts appears somewhat later, usually from 2 to 3 years. After that age they appear sensitization to vegetables, nuts and legumes.

2. What are the early symptoms of allergies? Is it easy to recognize?

In the vast majority of cases of allergy to the protein in cow’s milk the overt symptoms appear to coincide with the making of the first bottle of formula, or what parents believe is the first bottle, because sometimes it offered to the baby in the maternity ward, “usually in the first week of artificial feeding and after a rather long period of breastfeeding. In the box you will find the most common.

3. Allergic reactions occur only when food is eaten?

It is most common, although the intensity of the reactions depends on many factors: the amount of allergen ingested, or the child, the level of IgE present in blood, its sensitivity …-. Some very sensitive young may be submitted at the touch of food, and even when inhaled. The latter can happen with fish, milk or vegetables. Legume proteins cause reactions whether ingested as if breathed or inhaled with steam of the cooking water, and also suspended in it.

4. Can you be allergic to my milk?

It will not be to the proteins in your milk, but it can be to cow’s milk that you take and that will stop it. We know that, even in tiny amounts, the protein content of food taken by the mother pass into the milk you feed your child. Possible symptoms during this period can be mentioned and repeated vomiting or atopic dermatitis, including colic. If found evidence for a time to withdraw the milk in your diet and see if these symptoms disappear. Check with your pediatrician and discuss it your doubts.

5. He does not want the bottle: can be a symptom of allergies?

The stubborn refusal of the bottle has also been described as a sign of allergy to proteins in cow’s milk. But this is a very characteristic rejection, which is often confused with a simple dislike of the nipple, the baby cries, turns his face stiffens. In any case, it rarely appears as the only symptom and it will normally be accompanied by others, or that these other manifestations appear somewhat later.

Will I recognize the symptoms? What should I do if they occur? Do I need to remove food from my milk? Here are solutions to your questions about food allergy.

6. I’m allergic, “I can prevent him to inherit?

Genetic predisposition plays an important role in the development of allergic diseases. 60-70 percent of allergic children with a family history. In addition, the risk of future atopic disease is increased even further if they are both parents. The atmosphere is, however, a notable factor: prolonged breastfeeding, not to introduce different foods before 6 months and provide the most allergen-modified cow’s milk, egg and fish only from the year can be delayed, and sometimes prevent their occurrence.

7. If I suspect my child is allergic to milk, “I can offer a special for him?

The first thing to do is stop giving I was taking and go to the pediatrician as soon as possible. A doctor who has to advise what is the best formula for him. If tests confirm the allergy will have to make special allergist will recommend after reviewing his case. These children are not given type HA hypoallergenic formulas or partially hydrolyzed, nor should offer goat milk or sheep, which contain proteins similar to the cow and therefore also allergenic.

8. Is it more white fish allergy than the blue?

Yes fish most commonly cause allergic reactions in children are the cocks, sole, flatfish, hake and cod, all white fish. The reason, again, is that they are first introduced into the diet. The Blues are left for later because they are more fatty and difficult to digest.

9. “I can give you the egg before the year?

The egg is the most common cause of food allergy in children above the cow’s milk. Like milk, sensitization to egg white occurs early, even in children who receive only breast-feeding, by the passage of small doses of antigen by the mother’s milk. If there is a history of allergy in the family is better to delay its introduction until after the year. While it is true that most children react to the proteins of the clear and the yolk is not easy to separate the two parts without a “transfer” of proteins to each other.

10. When do you remove?

Sooner or later, it is usual that the allergy is gone. Year of life begin to tolerate milk between 28 percent and 56 percent of allergic children, between 60-77 percent tolerated at 2 years, and 71-87 percent after three years, although they continue to conduct periodic surveys to confirm that tolerance is complete and no problems. After 5 years the chances of overcoming allergies are decreasing, especially, apparently, if the child is very sensitive to casein, one of its proteins, and if their reactions are still important, asthma, anaphylaxis.
