Allergies or food intolerances are common in pediatric patients. Most children have mild reactions that disappear when they get older. There are also adults who are allergic to various foods.

Allergy and intolerance are different types of hypersensitivity. Are you allergic immune system reacts against the topic you are in contact with. Intolerance also a reaction, but then it is not immune to react.

Most people who have a food allergy, allergic to one or more of the following foods: eggs, milk, fish, shellfish, strawberries, legumes (soy beans, peanuts and peas), nuts or cereals.

Allergy in children

Thursday, April 22nd, 2010

Allergy in children can be triggered upon contact with allergens in our environment. This may include fur, pollen and foods. Skin prick test can show if your child is allergic. Contact care if your child has allergies.

Allergy is due to problems in the immune system. One of the immune system’s tasks is to produce antibodies that protect the body against bacteria, viruses and parasites. In allergic formed antibodies against harmless substances.

Why some children develop allergies and others do not still baffles scientists. Today, it is known that heredity plays an important role and that smoking may increase the risk, and that breast-feeding in some cases can delay that a child develops an allergy. One child, where both parents have severe allergies, are twice as likely to become allergic, compared with other child.

If a child is sensitive to a particular substance, it can either be due to an allergy or hypersensitivity. Symptoms tend to be strongest for sensitization.

The allergy can be to diagnose, treat and prevent problems in a different way than in case of hypersensitivity.

Symptoms of allergy in children

The most common symptoms of allergies are respiratory problems, eczema, hives and stomach problems.

Examples of common allergies in children

Rhinitis

Of all people in Sweden who has allergies is 40 percent allergic to pollen, also known as pollen. It is pollen from trees and grasses that are the most common causes of pollen allergy. A child with pollen allergy may have symptoms from spring to late autumn because the plants bloom at different times.

Common signs of pollen allergy are runny or stuffy nose, irritated, itchy eyes and sometimes asthma. Rhinitis can also make hives in the form of an itchy red rash on the body.

Fur Allergy

The most common fur allergy are allergic to cats. Cat allergens in the coat, in saliva and urine. These substances are easily transported by air and can spread to areas where there are no fur. It makes children feel very sensitive to their allergies even in environments without fur, as in kindergarten and in school.

Common signs of fur allergies are respiratory problems, like asthma and rhinitis. Other signs can include watery and itchy eyes, hives, and in direct contact with a fur.

Food Allergy

Food allergy means that the child can not tolerate certain foods, it may include eggs, peanuts, fish or milk. Typically, the proteins in food that causes allergic symptoms.

When food allergy is common with itching in the mouth, stomach upset as vomiting and diarrhea. Allergy to certain foods may also give hives and eczema worsen. In some cases, the airways are affected. The child may also experience an allergic shock. Read more about the shock link to the right.

Cows’ milk Allergy

It is particularly infants who are allergic to cows’ milk. It is often detected when the child will start eating porridge instead of milk. It is common for allergy grow out. At three to four years old milk can often be included in the diet again.

Common signs of cows’ milk allergies are vomiting, diarrhea, colic, eczema / rash and the child does not gain weight. Sometimes the child may have trouble breathing.

Insect Allergy

There are children who are allergic to insects and then often in bi-and wasp stings.

The most common allergic reaction is that the area around the sting becomes swollen and red. In severe allergic reaction can become very serious and cause allergic shock, that is, short of breath, hoarseness, confusion, hypotension and unconsciousness.

Celiac disease

Celiac disease, celiac disease, an intestinal disease that causes the intestine is damaged by gluten. Gluten is a protein found in wheat, barley and rye. Celiac disease is found mostly in the transition from breast milk to gruel. Intolerance do not grow out with time.

Signs of gluten intolerance may be stomach upset such as diarrhea or constipation, as well as the child grows poorly.

Lactose intolerance

Lactose intolerance is not an allergy but an intolerance to lactose. Lactose is a milk sugar which occurs only in milk products. Children who are lactose intolerant can not digest lactose in the intestine. When lactose is not broken down instead to begin the fermentation of bacteria in the colon.

In lactose intolerance, the child with stomach problems. It can be gas, diarrhea, bloating, noise, runs or colic pains.

Contact Allergy

Contact allergy may be caused by more than 3 700 substances. It has a different reason than, for example, pollen allergies. Contact allergy occurs when the skin over a long period in direct contact with an allergenic substance.

Give the allergy dermatitis in the form of small itchy blisters, mainly on the skin site exposed to contact with the allergenic substance.

Nickel is the most common cause of contact allergy. Other substances that can cause skin problems is a preservative and perfume. Contact allergy often begins already in children and adolescents and persists throughout life.

Prevent allergies in children

Where and how allergy can be prevented are discussed thoroughly among allergy specialists. The following advice can be offered under a public health perspective:

  • Do not smoke during pregnancy or breastfeeding.
  • Do not smoke inside.
  • Breastfeed your baby if you can. Breastfeeding has many beneficial effects, including the transfer of antibodies important for your child to help it to better cope with infections.
  • Have good ventilation indoors.

Self-care in allergy in children

If you know that your child is allergic, there is much you can do at home to prevent your child may be allergic disorders.

  • In pollen allergy, you may want to closely monitor pollen reports. To close the window, to avoid airing clothing outdoors and use preventive medicine as pollenhalterna is high is no way to prevent an allergic reaction.
  • For fur allergy, it is important to review the environment at home and think about that carefully clean clothes and other things that have been in contact with fur. The problem with kindergarten and school friends’ pet companions remain, but by telling the child’s allergy to kindergarten and school, perhaps you can find solutions.
  • Food allergies will be conducted in close cooperation with doctors and dieticians. This right to remove a source of nourishment and diet is balanced.

Study on allergy in children

It is important to study early if the child is allergic to any substance. This is to avoid that the child is exposed to the substances or environments that trigger the allergy, and to put the right treatment.

To find out if your child has an allergy is used for both blood tests and skin tests, so-called dot tests. When exposed skin prick test for multiple allergens during a short time to see if there is any allergic reaction. The subject you want to explore dripped on the skin, usually on the forearm. Then the “dots” are easily into the skin where the substance was dripping. Skin prick test can be done both to foods and allergy-causing substances in the air, such as pollen and threads from fur animals.

If your doctor suspects asthma, he or she investigates often the lungs. Children aged between three and six years to measure lung function with a so-called peak flow meters. Older children do a real test of pulmonary function, called spirometry. In both cases, measure how quickly the child can blow out air in the lungs.

Treatment of allergy in children

The basis of reading is that children are no longer exposed to the substance or the environment, which provides an allergic reaction. Contact with a dietician is an important factor in food allergy.

Sometimes it is not enough to avoid the substance in question, but the child must get medicine. There are both prescription and OTC drugs against different types of allergies.

Allergy (Hypersensitivity)

Monday, April 19th, 2010

Allergy and other hypersensitivity means that the body reacts to substances that we humans normally tolerate. Disorders due to hypersensitivity, you often in the eyes, nose, airways, gastrointestinal and skin. There is much you can do yourself to reduce symptoms. Contact care if you have difficulty breathing or if you have symptoms that do not go over.

Allergy and hypersensitivity

Allergy is included in the concept of hypersensitivity. The term stands for many different reactions that you may have of substances and environmental factors that we would normally tolerate. Hypersensitivity can be divided into allergic and non-allergic hypersensitivity. Here we report on allergic sensitization.

Allergic hypersensitivity is caused by immunological mechanisms. The immune system normally has a duty to protect the body against bacteria, viruses and parasites. Allergic sensitization can often confirm with various allergy tests.

If you have a hereditary tendency, known as atopy, you have an increased risk of developing allergies.

The most common allergies

Here are some of the most common allergies:

  • Rhinitis
  • Food allergy (food allergy)
  • Fur Allergy
  • Mites Allergy
  • Contact allergy with eczema
  • Bee and wasp sting allergy

You can read more about each allergy by clicking on links on the right.

Allergic reaction

When an allergy the first time in contact with such allergens, allergens, can start a reaction in the body that trigger allergic symptoms. You can be allergic to one or more allergens such as pollen, dust mites and animals.

The first time the body is exposed to an allergen production of antibodies that stick to a certain type of cells, mast cells. Next time you breathe in the allergen attaches to the antibodies on the mast cells. Mast cells are inter alia in the skin and in airway mucosa.

Mast cells then release from, among other things histamine affecting recipients, receptors in the mucous membranes and you have an allergic reaction. The mucous membranes of the nose and swollen eyes and itchy skin. Mucus production increases and you are sneezy. Airways swells, muscles to constrict and mucus glands produce, which makes you cough and, at worst, suffer shortness of breath, asthma.

Cross Reactions

Those who are allergic can have so-called cross-reactions and react to different foods. Cross-reaction is due to certain substances similar to the substance you are allergic to. It is not all that may cross-reactions and you do not respond to all subjects on the charts. Do you suffer from any one source of nourishment, you can continue to eat it.

Common cross-allergy is mainly itching in the mouth of the following foods:

  • Allergy to birch pollen may cause cross-reactions of apricot, hazelnut, kiwi, cherries, almonds, carrots, peaches, plums, potatoes, pears, celery, apple.
  • Allergy to mugwort may cause reactions if you eat anise, curry, fennel, chamomile, coriander, cumin, sage, carrots, peppers, parsley, celery, mustard, sunflower seeds, garlic.
  • Allergy to latex (rubber) may cause reactions if you eat avocado, banana, peanut, chestnut, kiwi, cherries, nectarines, plums.

Symptoms

Allergic symptoms, you get in your eyes, nose, respiratory tract, gastrointestinal tract and skin. The most common allergy affecting the airway.

Common allergic symptoms:

  • Lower respiratory: asthma with attacks of breathlessness, cough and wheezing
  • The nose: sneezing, itching, nasal congestion and runny nose
  • Eyes: itching and redness
  • Skin: hives, swelling, redness, blistering, peeling, cracking and dermatitis

Non-allergic symptoms

The signs of non-allergic näsbesvär is roughly the same. Such problems can you get to irritants and temperature changes, or if you have a cold.

Self-care

If you are allergic, it is important that you learn to live with your allergy to feel as good as possible. There is much you can do yourself to reduce the symptoms:

  • In pollen allergy, it is good to follow pollen reports in newspapers and on radio. During the summer months there is also pollen report on Care Guide website. Read more in the article on pollen allergy, see the link to the upper right.
  • Close windows and take preventive medication when pollenhalterna is high.
  • Do not use clothing or jewelry that you may contact dermatitis of. Are you allergic to preservatives and fragrances, there are special allergy-free hygiene and cleaning products to buy.
  • Avoid foods you are allergic to.
  • Stop smoking. Smoking impairs respiratory symptoms. Aids to quit smoking is a prescription at the pharmacy. In many clinics are smoking cessation courses.

Find Care

Hospital emergency rooms

The rapidly emerging difficulties in breathing, you should seek immediate emergency medical treatment.

Medical Center

Contact your GP if you experience:

  • respiratory symptoms as wheezing, wheezing or persistent cough without a cold
  • skin irritation that does not disappear
  • itching and / or watery eyes
  • runny nose, sneezing, the stuffy nose without a cold
  • long-standing problems with nausea, loose stools and stomach-ache
  • If you have questions about allergies and intolerances

The address and telephone number of a kind reception, go to Find Health Care. You can also contact some receptions and order a time via the Internet. Click on My care contacts.

Investigation

The first step in an allergy study is that the physician carefully identify the disease history. It is important to investigate what caused the symptoms to alleviate and prevent them.

To find out if you have an allergy can be a simple skin test, known as skin tests. When the test dot dropped some of the most common allergenic substances in the lower inner arm. A blunt needle is pushed gently through the straw so that the allergen entering the skin. If you are allergic to the subject area is a bit red and swollen.

One can also take blood tests to check for allergy antibodies in the blood. The respiratory problems are examined lung function by spirometry study. Read more in the article on spirometry study.

Treatment

The goal of treatment is that you can live as normal a life as possible without having to limit your daily life. Treatment usually consists of both medication and environmental improvement measures. At such fur allergy, it is important that, wherever possible, reduce contact with the fur. The mite allergy can be a so-called protection of mite mattress and pillow might be an option.

Pharmaceuticals

There are many good medicines. They can be divided into two groups: prevention and mitigation. There are medicines for different types of hypersensitivity, such as in allergic rhinitis or allergic inflammation of the conjunctiva.

Immunology

When our immune system encounters foreign substances, such as bacteria and viruses, it forms antibodies to these substances. Immunoglobulin antibody is the active component in blood plasma.

Primary immunodeficiency

Some people have a defect in their immune system which means that their antibody production completely or partially absent (PID). This means that they become highly susceptible to bacterial infections in particular and also find it hard to combat the infections they suffer. They may be lengthy and repeated infections, pneumonia. Eventually, the chronic damage in the airways and lungs.

The regular administration of immunoglobulin, their resistance to infection significantly improved and the risk of chronic injuries avoided.

Immune Modulation

Some diseases are caused in whole or in part by immunological mechanisms. In some individuals an imbalance in the immune system, for example, which can lead to increased risk of bleeding (eg, idiopathic thrombocytopenic purpura, ITP).

An imbalance in the immune system can also cause specific diseases that cause inflammation in the body’s nerves and organs
(Eg Guillain-Barre Syndrome).

These diseases are called with a common concept and autoimmune diseases involving the immune system mistakenly perceives the body’s own tissues (eg neurons) as foreign and therefore attacks and destroys them.

It is not yet entirely clear how the flow of immunoglobulins in these cases affects the mistaken immune response. Probably, however, several mechanisms that work together to neutralize and regulate the faulty immune system and thereby restoring the immunological balance. This type of treatment known as immune modulation.

Rh-immunization

Rh-negative – what is it?
On the red blood cells are a variety of topics attached. Some of these are those underlying the division into different blood group systems, the most famous is the AB0 system, rhesus (Rh) system.

Rh system most significant factor is called the Rh factor, or D-factor (hence the name anti-D immunoglobulin). Approximately 85% of the Swedish population has this element and are called Rh-positive (Rh +) while 15% lack this and are called Rh negative (Rh-).

If an Rh-negative woman is pregnant with an Rh-positive fetus (which can happen if the husband is Rh-positive) may be Rh-factor on fetal blood cells stimulate the woman’s immune system to produce antibodies which are directed against the Rh factor. The pregnant woman can then be Rh immunized. This is done primarily at the end of pregnancy and during labor. By adding anti-D immunoglobulin to Rh-negative woman immediately after birth can prevent immunization.
