Allergic skin diseases Overview: The most common allergic skin diseases are eczema, dermatitis and urticaria. Their skin manifestations are erythema, papules, blisters, vesicles, oozing, and wind clumps, etc. Pruritus is a common and prominent symptom of these diseases. The pathogenesis of allergic skin diseases is complex and is generally considered to be related to genetics, immunity, environmental factors, and psychiatric factors, and its pathogenesis is related to type I-IV allergic reactions or some non-immune mechanisms. Allergen detection and desensitization treatment At present, allergens can be detected by puncture test, patch test, Mora test, serum IgE antibody, and physical and pharmacological desensitization treatments are used to achieve better results. 1.MORA Mora biophysical therapy instrument is used for allergen detection and diagnosis and desensitization treatment using bioelectromagnetic wave resonance technology. Main treatment diseases: eczema, urticaria, allergic purpura, allergic rhinitis, allergic asthma, contact dermatitis, atopic dermatitis. Treatment features: painless and non-invasive detection of allergens; detection of more than 1500 allergens within 1 hour; no need to take any medication during treatment without special circumstances. 2.Spot prick test: Allergens are injected into the dermis and combined with the corresponding IgE on the surface of mast cells in the tissue, which can cause the release of histamine and other vasoactive substances in a short period of time, causing the skin of the test site to produce a wind and redness reaction, so as to determine whether the patient is allergic to a substance. 3, patch test patch test is the test substance in direct contact with the skin to observe the skin reflection, it is often used to detect contact dermatitis allergens; patch test is a late reaction, 24-72 hours after the test to observe the results, mainly for contact dermatitis, eczema, cosmetic dermatitis and other disease detection. 4, serum IgE antibody test is an enzyme instead of radioisotope labeled anti-human IgE to determine the specific IgE in the sample, this method requires only a small amount of serum, it can do a variety of allergen testing, high accuracy, safe and convenient for patients; mainly used for the detection of atopic dermatitis, urticaria, eczema, bronchial asthma, allergic rhinitis and other diseases.
