Top 5 strange allergies

Many times, even the outline of some letters on one's skin can leave traces. This is called dermographism. It is known in the constitutional variant, about 5-7% of the population, but it can occur during each of the lives of each of us, usually associated with parasitoses, bacterial or viral infections, but also post-drug. These lesions, which are in fact urticaria papules, can disappear spontaneously. Not a few times, however, a facticial or dermographic urticaria evolves chronically and requires prolonged treatment with various combinations of antihistamines. Do not confuse dermographism with presidential urticaria, where lesions occur between 4 and 6 hours after application of skin pressure, such as wearing a heavy bag on the shoulder or the one carried by a strap or elastic.

Even sitting for a long time can cause urticaria in your thighs or buttocks, if you support too much your forearms on your desk, A simple test can be used to diagnose it. This involves the application of water compresses to the skin at room temperature and skin observation for 20-30 minutes after. This type of hives is quite difficult to manage and will require daily treatment, Flare or cold urticaria, as the name says, occurs especially in the cold season, on exposed areas such as the face, neck or hands. Upon entering a heated environment, the manifestations will gradually disappear and the affected areas will gradually return to normal. Otherwise, urticarial eruptions also occur on areas covered by clothing, which are exposed to a cold air stream that can penetrate relatively easily through the fabric.

The most severe form of this allergy appears paradoxically even in the summer when, after exposure to the sun, people with a cold allergy suddenly dive into cold water from the pool or the sea. Sudden exposure of a large skin area to a lower temperature can lead to severe allergic reactions, including anaphylactic shock, When a person with cold urticaria consumes cold food or liquids, the same manifestations may occur in the mucous membranes. Otherwise, for the occurrence of cold allergy manifestations, it is not necessary to expose the skin to low temperatures, but there are sufficient variations of several degrees. The classic test used by allergologists to confirm the diagnosis of cold urticaria is the ice cube test, and this is because, for each patient, there may be a critical temperature threshold from which the skin starts to react.

Thus, with the emergence of urticaria, it is preferable to use a special device with which it can determine. Unfortunately, few diagnostic centers have this kind of equipment, Often, a cold allergy can actually express the existence of other health problems such as infectious, parasitic or viral outbreaks. Whatever its real cause, in cold urticaria, special precautions for exposure to cold are required, which include a warm clothing made of heat-insulating materials, food and liquid consumption at room temperature. It is often necessary for high doses of antihistamines, to which cortisone preparations can be added, and severe forms of physical urticaria are reserved and a treatment with anti-IgE monoclonal antibodies When the application of an electric pillow is accompanied by redness, itching and the appearance of urticaria papules at the site, we discuss another strange form of allergy.
