Why the same substances are completely harmless to some people and cause hypersensitivity reactions in others is not yet fully understood. It is assumed that in patients sensitive to the scarification skin test (superficial scratching - scarification - of the upper layer of the skin, followed by the application of an allergen to this scratch), excessive production of antibodies responsible for an anaphylactic shock reaction is a hereditary gene phenomenon. In other cases, prolonged contact with a highly concentrated substance can sometimes lead to a hypersensitivity reaction to that substance.

The body's defense system can begin to attack and destroy its own blood cells - red blood cells, which sometimes leads to buy cheap ceftin online. Recently, a hypothesis was put forward by the scientific community of allergiststhat the development of hypersensitivity reactions is caused by a violation of the mechanism that normally prevents the penetration of potential allergens into body tissues. Most types of hypersensitivity are diagnosed by a prick test, in which a drop of the allergen is applied to the skin and a thin needle is pricked under this drop. Note that hypersensitivity to a food product can be manifested by dyspepsia and indigestion that occurs with each consumption of such a food product. If it is not known which food is causing the allergy, the allergist prescribes several different diets, each of cefuroxime pills eliminates a particular food.

So, the cause of contact dermatitis is also obvious if it is caused by wearing any jewelry that comes into contact with the skin. In doubtful cases, the doctor can identify the allergen by examining the skin reaction to various chemicals that the patient usually comes into contact with at home and at work. Some types of allergies are eliminated by taking medications or by the method of so-called injection desensitization (reducing or suppressing the hypersensitivity reaction by regularly administering the allergen in certain doses). It is worth considering that one injection should not contain more than three allergens.

The best results are achieved with desensitization against mites and pollen (80% effective) and insect bites (over 90% effective). Desensitization to buy cefuroxime pills hair is usually not effective. In the case of fungal and food allergies, the effectiveness of desensitization is also negligible. Anaphylactic shock or anaphylaxis, a rare manifestation of hypersensitivity that occurs as a result of taking a drug or an insect bite, requires urgent medical attention. Shock is usually treated with injections of antihistamines and epinephrine. Read more about hypersensitivity, symptoms and manifestations of this condition in our other articles.

Hypersensitivity of the skin or hyperesthesia is a pathological condition of the skin, in which even minor external influences on them cause the development of a very strong reaction. Such a pathology most often becomes a consequence of a malfunction of the nervous system. Hyperesthesia of the skin can be local (local) in nature, when sensitivity is increased only in one limited area, and general, when there is hypersensitivity of the entire skin. Causes of skin hypersensitivity. The cause of ceftin hypersensitivity may be an increase in the sensitivity of skin nerve endings. This is observed with wounds, burns, herpes zoster infection, eczema, atopic dermatitis. The same form of skin hypersensitivity is observed in radiculitis and neuritis.

There may also be a central form of hyperesthesia, in which the excitability of nerve cells in the central nervous system increases.

In this case, the entire skin is affected. This condition can appear with benign and malignant tumors, multiple sclerosis, encephalitis, meningitis, chronic poisoning with various poisons, chemicals, alcohol or drugs.
