Skin allergies

Skin diseases with itching may be caused by the contact of some substances with the skin or mucous tissues.
In this case, the skin becomes inflamed and itches and may even blister.

Hives or skin sensitivity with itching, fever and blisters or, as medical science calls it, urticaria have many exact similarities with the effects of skin contact with the plant (nettle).
This reaction is the result of the release of histamine from our cells.
“The relationship between dog and dog hair and saliva allergy may cause skin sensitivity” Blisters may appear in any part of the body and usually disappear within a few hours.
Out of every five to ten people, one person has been affected by hives at least once in his life.
If a dog licks the face of a person who is allergic to dogs, a red blister will develop in the place of the lick.
People who are allergic to food usually have swelling of their lips or oral mucosa after eating eggs, cow’s milk or hazelnuts.
These symptoms of urticaria or sometimes due to the intolerance of contact with chemicals such as ammonia, bleaches, substances used in canned foods, nettles and dark primrose flowers also appear.

This fruit is one of the most important allergenic foods and can cause hives all over the body.” When you eat something that you are allergic to, your whole body may get hives. The
most important allergenic foods are cow’s milk, eggs Nuts, fish, shellfish, beans, potatoes, celery, parsley, and all kinds of spices.
If someone is allergic to bee stings, he will probably get hives, like penicillin And acetyl salicylic acid may cause hives in sensitive people.
Some people also get hives under the influence of cold, heat or pressure.
Congenital deficiency of a type of hives may be the cause of hives in the family It may be a sign of this problem.
In the case of chronic and severe hives, the person’s body may act against itself, which means that the human body acts by making itself, which means that the human body makes antibodies against the cells. Yogurt produces histamine,
in this case it should be done through subcutaneous tests or blood tests to identify the allergen.
If necessary, the elimination diet is also an effective help. There has already been an article on the elimination diet on the site, please read it. They prevent the activity of histamines that are released by mast cells under the skin and cause itchy blisters. Taking a non-analgesic antihistamine such as cetirizine or loratadine once a day will quickly reduce the effects of hives.

 In the case of angioedema or tissue swelling, the lower layers of the skin, especially in the face, tongue and throat area, get hives and swell.
Histamines released from mast cells along with other messengers increase the permeability of the capillary wall, and in this way, blood seeps from the capillaries into the tissues and swells the tissues.
Angioedema is closely related to urticaria and these two may actually have a common cause.
The main cause of tissue swelling, which accounts for 75% of cases, is acetylsalicylic acid and other anti-inflammatory drugs such as ibuprofen, which is structurally similar to acetylsalicylic acid and does not contain steroid compounds (cortone).
In some rare cases, acetaminophen with the active ingredient paracetamol has the same effect. Preservatives used in canned goods, food colors, especially benzoic acid, ascorbic acid, paraben, types of sulfites and antioxidants should be avoided.
Also, the new generation of antihypertensive drugs of the ACE-I group (drugs that act by inhibiting the angiotensin converting enzyme) can cause hives or severe tissue swelling. In case of swelling of the tongue or the mucous tissue of the mouth and around the throat, it may be necessary to inject adrenaline.
Itching and flaking of the skin is the most common cause of itching, dryness, flaking, red and watery skin blisters, skin nerve sensitivity and contact eczema.
Allergic eczema usually appears as pimples on the face in two to six months.
Pimples may spread all over the body, but usually do not appear around the baby’s diaper.
The effects of pimples disappear in 50% of children by the age of 18 months, and in the rest of the children, pimples are mostly in skin folds such as the back, elbows and knees, under the chin and throat, back of the neck, wrists and The legs remain.
It has not yet been determined to what extent sensitivity to mites, pets and food is effective in the formation of eczema, but the results of research show that environmental factors and biological conditions are at least as effective as genetic factors in the formation of children’s eczema.
It seems that factors such as the number of carpets and rugs in the room, the presence of a heating and central heating system in the home, which makes the environment suitable for the growth of mites, the type of soap used and the number of times it is used, exposure to radiation Ultraviolet, contact with animals, mother’s age and type of nutrition are the most important influencing factors. 75% of children who suffer from severe neurodermatitis (neural eczema) have a high concentration of IgE (Immunoglobulin type E) in their blood, and the adhesive tape test with such allergens gives positive results in their case. Infecting the eczema wound with the condition mite It worsens the wound. (Placing a hand wound with eczema on the carpet) In the pollen season, some allergic patients also have eczema blisters around the nose and eyes. 25% of people with neurodermatitis They are allergic to eggs, cow’s milk, types of hazelnuts, wheat, fish and shellfish. Symptoms of neurodermatitis usually appear after the end of infancy.
The first sign of effective improvement is observed when foods prepared with milk products are given instead of cow’s milk. Children whose parents have allergies carry the risk of developing allergies from the moment of birth. Treatment of neurodermatitis begins with skin hygiene and maintenance, which requires plenty of oil and moisture. On the other hand, you should avoid perfumed products. Regular soaps and shampoos and water showers without any detergent are very beneficial.
Lubricate the skin several times a day using base oils, without cosmetic and perfume additives. If hygiene and skin care alone are not enough, you should use creams and creams containing coronet. According to the general rule of using corticosteroid drugs, one should always use the weakest effective amount (an amount that is sufficient for the current condition of the disease) and alternately use simple creams without corticosteroids in between using corticosteroid creams. In most children, the use of corticosteroid cream is more, it should be used with full caution and for a limited time.
Some patients get a favorable result by using evening primrose oil.
160 to 320 mg per day for children and 320 to 480 mg per day for adults for three months can be effective. But if at the end of this period no improvement is observed, its continuation will be useless. The use of antihistamines in cases of neurodermatitis is not very reasonable.
Worsening of the condition of the eczema wound may be due to a secondary infection of bacterial origin, which is treated with antibiotic treatment.
Such secondary infections should be treated according to their origin. Allergic contact eczema: Allergic contact eczema, unlike neurodermatitis, occurs less often in young people. Eczema appears after the sensitivity period, the duration of which varies depending on the strength of the allergen. People who are in contact with allergens in their profession are more at risk. Acute allergic contact eczema usually appears as a red spot on the skin two days after contact with the allergen, and after that, swelling and small and large blisters similar to a superficial wound with a horny crust appear.
If the contact with the allergen is stopped, the effects of eczema usually improve within a week, and if the contact continues, the eczema becomes chronic: the skin remains red, the thickness and swelling of the skin increases, and the skin folds. It becomes more violent.
Eczema wound is first limited to the place of direct skin contact with the allergen.
In two-thirds of the cases, hands are more at risk due to direct contact with allergens

Some people are allergic to chemicals that are used in everyday products such as cosmetics, bleaches, decorations and life accessories.
This sensitivity is diagnosed using adhesive tape test, and its treatment is to avoid the allergen.
Nickel: This metal is used in clothing zippers, eyeglass frames, decorative items, household items, and coins.
Chromate: It is used in the preparation of leather, bleaches, match heads and cement.
Formaldehyde: It is used as a preservative used in canned goods, cosmetics, nail polish, printing compound, disinfectants, cigarette smoke, floor cleaners, chipboard and anti-wrinkle fabrics.
Ethylene diamine: It is used as a preservative in cans, creams and colors.
Mercaptobenzothiazole: It is used in rubber products, especially rubber tubes, boots and gloves.
Thiuram: It is used in rubber products and as a fungicide in paint and soap.
Plants: primrose, poison sumac, daffodil and chrysanthemum are allergenic. Many perfumes and cosmetics, eye lotions and sunscreens contain ingredients that increase the skin’s sensitivity to sunlight.
The sensitivity to rubber and natural latex increases every day.
This material is used in the preparation of items such as condoms, suppositories for women, and disposable medical and household gloves.
Those who work in health professions and are in constant contact with these materials are often allergic to rubber and latex
. Substances range from allergic eczema limited to the hands to hives and even asthma and anaphylactic shock leading to death.
People who are allergic to these agents should ask their doctor to use non-latex gloves when going to the dentist or surgery.
Here too, the use of warning bracelets and necklaces is useful and life-saving.
Cosmetics that are the least sensitizing: 60% of women say that their skin is sensitive.
For this reason, the market of cosmetics that are the least sensitizing becomes more and more popular day by day.
Lanolin, fragrances and preservatives are the most important factors that cause skin sensitivity. If your skin is sensitive or prone to allergies, it is better to use non-scented cosmetics with as few coloring ingredients as possible, because both dyes and fragrances are allergens.
