Allergic Conjunctivitis in Children

Tuesday, November 29th, 2011

Allergic Conjunctivitis in ChildrenAllergic conjunctivitis is a disease characterized by inflammatory condition that directly affects the conjunctiva, which is a thin mucous membrane covering the eye and lines the inner surface of the eyelid, so that the eye provides a primary barrier against environmental aeroallergens, chemical and infectious.

Etiology is an entity caused by various causes, among the most important are the following:

Allergens: pollen, dust mites, fungi.
Chemicals: snuff smoke, fumes, solvents, environmental pollution, food additives and colorings.
Physical causes: contact lenses.
Epidemiology: incidence is unknown, but 80% of patients with allergic conjunctivitis is associated with allergic rhinitis, asthma and atopic dermatitis, is less frequently associated with drug allergy, food allergy or urticaria.

It occurs more frequently in children in two ways: as a single disease, this being the least common presentation, or other disease associated with allergic conditions. (more…)

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.

The scheduled introduction of milk in childhood protects against allergic to dairy

Tuesday, November 15th, 2011

milk in childhood protects against allergic The scheduled introduction of cow’s milk at an early age can desensitize patients ie to prevent the allergic reaction, according to a study by a group of pediatric allergists, belonging to the Spanish Society of Pediatric Allergy and Clinical Immunology (SEICAP), published in the Journal of Clinical and Experimental Allergy. “

The main novelty of this research, according to its authors, is not only high effectiveness of this specific induction therapy but the sooner you make, the more effective it is. “It has been shown that the success of this pattern is greater if administered within three years. In studies with older children, the success rate is lower,” he noted Dr. Antonio Martorell, General Hospital of Valencia, study’s lead author.

The study, which was conducted in Allergology services and units of 11 Spanish hospitals with allergic children between 24 and 36 months of age, reveals that in 9 out of 10 children tolerance to cow’s milk increased after that ingest progressively. The avoidance of food, the standard therapy, scored only 1 in every 10 children. (more…)

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

Tuesday, July 19th, 2011

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 the 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.

A controlled delivery reduces infant allergy to milk and eggs

Friday, July 1st, 2011

The Hospital Madrid has been demonstrated in a study of 80 pediatric patients, with children four years allergic to lactose, and other five with intolerance to any component of the eggs that the solution to allergies food supply is controlled of these foods under medical supervision and with the help of suitable drugs.

When you pass this initial phase, controlled increases the amount of food consumed and, at a certain point, you should perform maintenance. Thus, children should be kept in the dietary intake of a daily glass of milk and one egg per week, equivalent to almost its normal consumption.

These are allergies more common in children , affecting up to 8 percent of children under 3 years. Thus, this disease is a major public health problem, as its diagnosis involves diet restrictive and results in a loss of quality of life for patients and their families. Until recently, treatment was to wait until the patient reaches the tolerance spontaneously and looking for the right time to introduce the food. According to experts, in the case of allergy to cow’s milk can reach 80% tolerance before 4 years, but 20% of cases the allergy remains to maturity, and patients have ” allergy persistent cow’s milk proteins. ” If something happens egg and tolerance spontaneously reach about 60 percent of patients within 5 years.

Symptoms of food allergies in children

Tuesday, May 31st, 2011

 allergies in childrenIt is believed that about 5% of children have or have had an allergy caused by some food.

Food allergies have a strong hereditary component, but also associated with environmental factors and the early introduction of food.

The foods that most commonly cause allergies are peanuts, dairy products and eggs. It is curious to know that most allergies are caused by just five foods: peanuts, peanut Butter, egg, cow milk products and derivatives, and soybean and wheat. It can also cause it, although less frequently, chocolate, strawberries, tomatoes or seafood.

When a child eats these foods, if you are allergic to them, the body produces an immune response manifesting some symptoms after eating.

Let’s see what are the symptoms that allow us to suspect that the child may suffer food allergies .

There are three types of events that can occur in combination.

Digestive symptoms :
1. Swelling, especially around the mouth (lips, tongue, face, eyelids sometimes)
2. Difficulty swallowing
3. Abdominal pain, cramping, diarrhea, nausea and vomiting
4. Skin manifestations :

Itchy skin: the appearance of local or generalized urticaria
Rash or hives on the skin
Atopic dermatitis , inflammatory skin disease very common in young children
Respiratory manifestations :

Bronchial asthma
Rhinitis (nasal congestion)
Bronchospasm
Rarely there may be anaphylaxis immediately after eating the food. Is a drop in blood pressure, shortness of breath and unconsciousness. If this happens, requires immediate medical attention.

With respect to the time that symptoms may appear, are classified into three:

Immediate: begin within minutes after eating the food, usually within the first 30 minutes. Cause-effect relationship is very obvious and the most common symptoms are vomiting, urticaria, asthma and anaphylaxis.
Deferred : are symptoms that appear after two hours of eating the food. The most common are gastrointestinal symptoms such as diarrhea associated with protein-sensitive enteropathy.
Late : appear days after eating the food, such as atopic dermatitis.
It is very important to observe the child after giving one of the most common foods that cause allergies, especially when they are consumed first. If you notice any of these symptoms associated with food you should consult with your pediatrician who will conduct testing to confirm allergy or not.

The treatment is to avoid the food you are allergic to the reaction subsides, but do not remove the food until they confirm that it is an allergy because there are times when food allergy is attributed when you really are not.

Food Allergies

Friday, May 27th, 2011

Usually the food allergies begin in childhood, so it will be of vital importance to recognize the symptoms appear so that in this way can prevent and treat food allergies .

Be declared by vomiting, persistent diarrhea, abdominal pain, eczema, rashes and sometimes wheezing or fatigue, occur when the child’s body reacts to food as if it were a foreign substance and harmful, so it creates antibodies that generate the above symptoms.

These may be due to various different causes and is a little hard to know if you are against this type of allergy or not, so it will be very important to consult a specialist if you think your child is allergic to a particular food.

This reaction does not appear immediately, but may show symptoms and appear as late as 48 hours after eating the food. Just after 6 months of age, with the introduction of solid food allergies caseload has been reduced dramatically.

Anyway there are foods that are considered more harmful than others and which must be eliminated in the diet of children up to one year of age or up to two years if there is also a history of allergies in the family.
