Allergy

Tuesday, November 22nd, 2011

The use of pillows and bedding made with feathers has been long considered as a potential source of allergens. Therefore it is common to recommend to people, especially those suffering from allergies, the non-use of bedding made with feathers, even when the evidence against it is not very important. Recent studies have shown that cross-bedding made with synthetic compounds is associated with various respiratory effects at. In addition, synthetic pillows contain higher concentrations of different types of allergens compared with those made with feathers. Given these conflicting results would be weak evidence for recommending the use of bedding made with synthetic materials. In a Scandinavian study prospectively evaluated the relationship between the use of bedding made with feathers and frequency of respiratory effects through the monitoring of children up to age 4 years.

Methods
We included children born in Oslo two major clinics over a period of 15 months, a total of 3 754 children. The study included follow-up at 6, 12, 18 and 24 months, and then at 4 years as part of a cross-sectional population-based 4-year-old Oslo in 1996. The proportion of participants at follow-up was 81% at 2 years and 67% at 4 years. The primary effects were to evaluate bronchial obstruction during the first 2 years and current asthma and allergic rhinitis at 4 years. Bronchial obstruction was defined as the presence of 2 or more episodes with symptoms and signs of obstruction or one episode lasting more than 1 month in the first 2 years of life. One of these episodes should have been diagnosed by a physician, with at least three of the following signs and symptoms: wheezing, respiratory depression, stridor, and tachypnea forced expiration.

Infant allergy to milk and egg and cure

Friday, July 22nd, 2011

Children who suffer from food allergies to milk and eggs can be treated for the first time thanks to a program developed by the Hospital Gregorio Maranon (Madrid). Treatment consists of artificially induce tolerance to these foods by desensitization based on the administration of small amounts of milk or egg, which gradually increased until it takes the amount of a usual without adverse allergic reactions.

The number of children with food allergies is increasing in Spain, especially milk and egg. Natural history, says Elena Alonso, Hospital Gregorio Maranon, is to move towards tolerance, and most of those affected healing ends. In the case of milk, 85% heal spontaneously within four years, and in the egg, 75% at five years of treatment. However, he says, a small number of children who are not cured and must live with a complicated diet free of milk and egg. In these cases, allergy becomes persistent, which reaches 15% of children who can not drink milk, and 25% of the egg.

Until now there were two types of treatment to avoid these foods and products containing them, and symptomatic treatment of accidental ingestions. Nevertheless, says Alonso 67% of children over four years with allergies to milk allergy has been an episode in the previous two years, 80% have experienced changes in their daily lives, and 85% have had any problems with extracurricular activities. According to the Spanish Association of Food and Latex Allergy to (Aepnaa), 18% of allergic reactions in children occurs in schools. (more…)

Childhood allergy to cow’s milk

Childhood allergyAt the regional level is not known accurately the prevalence of allergy to cow’s milk. Its incidence is not known world, which seems to be very variable. So say experts from the World Allergy Organization (WAO, according to its acronym in English) and other scientific institutions in a paper published in the journal Current Opinion in Allergy and Clinical Immunology. “This allergy is the result of an exaggerated and damaging immune system to certain proteins in cow’s milk. Your symptoms may be gastrointestinal reactions, skin, or respiratory tract (respiratory symptoms).

There are rare cases where a severe allergy such causes anaphylaxis is a generalized reaction of the immune system can become serious, “said the Agency CyTA a member of the panel of experts convened by WAO, Dr. Carlos E. Argentina Baena-Cagnani, who serves as academic director of the Center for Research in Respiratory Medicine, Faculty of Medicine, Catholic University of Cordoba. He added: “To determine the prevalence of this type of allergy that affects children early in life-usually up to four years-old, is one of the challenges we face today. “According to Baena Cagnani children can have two kinds of unwanted side effects due to intake of cow’s milk, one is the intolerance and other allergies. Many times the symptoms are confused, but what is the difference? “The difference is that intolerance is not immune mechanisms involved. A well-known case is the lack of lactase.

In this case the children lack the enzyme that aids digestion of lactose, a sugar found in milk. In contrast, allergy is a response from the defense system turns against the body, “says the specialist who also serves as a member of the Executive Committee of the Global Alliance against Chronic Respiratory Diseases (GARD, according to their acronym in English) of the World Health Organization. underdiagnosed Allergy missing While epidemiological studies on allergy to milk the cow, Baena-Cagnani noted that the clinical evidence in several countries shows that “there are many cases of misdiagnosis Allergy to cow’s milk in a double sense.
