The child has a red pimple on his face outdoors, but it will be fine if he stays indoors for a while. How is it?

There are two kinds: familial and acquired. The former is autosomal dominant inheritance, which can occur after birth or early years and last for life, and may be accompanied by fever, chills, headache, joint pain and so on. When cold happens; Neutrophils increased, and passive transfer test was negative. The latter is more common in young women. After catching a cold, wheal or patchy edema appears in the contact or exposed parts for 30 minutes or several hours. Sometimes eating cold drinks can cause edema in the mouth and throat, and the passive transfer test is positive. This disease is characterized by itchy edema and wind mass in the cold area after contact with cold water or other cold substances, which can disappear in about half an hour to 1 hour. Most of them are exposed parts such as face and hands, and other parts can be involved in severe cases. Mouth, tongue, pharynx and other mucous membranes will also have edema and even abdominal pain when they encounter cold food or cold drink.

1, family inheritance:

There may be two reasons for the onset of cold urticaria. First, the disease has the characteristics of family inheritance, and the patient's parents may have the disease and pass it on to the next generation;

2. Acquired:

Acquired cold urticaria can be divided into primary and secondary. Histamine is the most important inflammatory factor, but prostaglandin and kinin are related to the occurrence of this disease. Histamine releasing factor exists in the blood of patients with spontaneous cold urticaria. The wheal or normal skin of patients with this disease can induce wheal after cold stimulation. Secondary cold urticaria is closely related to some diseases, such as cryoglobulinemia, cold fibrinogen, infectious mononucleosis, rubella, HIV, syphilis, connective tissue disease, bone marrow malignant tumor and so on.

It is acquired by the patient and related to the patient's personal physique. For example, patients stay up late, fatigue leads to low immunity, or some diseases lead to decreased immunity.

urticaria

At present, western medicine has no specific treatment for urticaria, and most of them are oral antihistamines and corticosteroids, such as oral western medicine, oral hormones, lotion for external use, emulsion, mud paste, oil, ointment, emulsion, film coating agent, tincture, plaster and so on. Long-term or high-dose topical use of corticosteroids can lead to addiction and drug dependence. The most common thing is that the condition gets better after taking the medicine. Once the medicine is stopped, the primary disease of the medication site gets worse. When the hormone is used again, the above situation improves or disappears; If the drug is stopped again, the rebound will recur and be more serious than before.

In order to avoid the pain after stopping taking drugs, patients are totally dependent on hormones. The skin will obviously become thinner, the capillaries will dilate, and sometimes purpura will appear, especially on the face, which can cause deep persistent erythema. The longer the hormone is used, the heavier the rebound allergy will be. Can make the skin thinner, fragile, atrophic, telangiectasia, purpura, fungal infection, acne-like dermatitis and so on. Become fragile; Mild hirsutism, hyperhidrosis, subcutaneous hemorrhage and difficulty in wound healing may also occur. Especially for some skin diseases, hormone preparations are not suitable.

Long-term or short-term high-dose injection or oral administration of corticosteroids such as dexamethasone, Kangning Ke Tong and prednisone can also cause obesity, hirsutism, acne, hyperglycemia, hypertension, edema, hypokalemia, menstrual disorder, osteoporosis, aseptic osteonecrosis, gastric and duodenal ulcers and other complications. It can also cause certain damage to the kidney, such as aggravating glomerular disease proteinuria, aggravating glomerulosclerosis, easily causing renal calcification or calculus, inducing or aggravating renal infectious diseases, and causing hypokalemic nephropathy. It can also cause metabolic disorder of a series of substances such as sugar, protein, fat, water and electrolyte, destroy the body's defense system and inhibit immune response.

urticaria

Avoid eating foods containing artificial additives and eat more fresh fruits and vegetables. Fried, fried or spicy foods are unlikely to cause thermal reactions in the body. Don't apply hot compress: Some people itch enough to apply hot compress. Although heat can temporarily make local itching less sensitive, it is actually another stimulus, because heat will dilate blood vessels and release more allergens, such as soaking in overheated hot springs or bathtubs, or wrapping in thick quilts to keep warm, which can easily cause urticaria. Eating more fresh fruits and vegetables rich in vitamins or taking vitamins C and B, or B6 in group B, can effectively prevent urticaria. Alkaline foods such as grapes, green tea, kelp, tomatoes, sesame seeds, cucumbers, carrots, bananas, apples, oranges, radishes, mung beans and sweet kernels. How to prevent cold urticaria in winter is a kind of urticaria and belongs to allergic skin disease. With the arrival of cold air in late autumn and cold weather in winter, the number of patients with cold urticaria has gradually increased. The cause of the disease is not completely clear, and some patients are related to heredity. It may be that normal skin protein or denatured skin protein released after skin is stimulated by cold stimulates the human immune system, leading to allergic reaction between them, or that some antibody macromolecules in human blood accumulate after cold. The above reaction causes immune cells to release inflammatory factors such as histamine, so that the small blood vessels of the skin dilate and congestion, the intercellular space of the blood vessel wall increases, and blood components such as plasma proteins ooze from the blood vessels, resulting in local skin blisters or edema. Cold urticaria can be divided into familial and acquired types. The former is a hereditary skin disease, which starts from the baby, and the symptoms decrease with age, often lasting for a lifetime. Acquired cold urticaria can be divided into primary and secondary. The occurrence of primary cold urticaria is related to inflammatory factor histamine. The incidence of secondary cold urticaria is closely related to systemic diseases such as rubella, syphilis, cryoglobulinemia and connective tissue disease. Once suffering from cold urticaria, how to treat it? Antihistamines and leukotriene antagonists or their combination are commonly used in western medicine. Traditional Chinese medicine believes that this disease is caused by exogenous wind-cold and imbalance, so strengthening the body resistance and dispelling cold and harmonizing ying and Wei are its basic treatments. Low dose glucocorticoid is effective for some patients. Antibiotics such as penicillin or tetracycline can completely relieve some patients or improve symptoms. For patients with poor effect of routine treatment, cold tolerance treatment can be considered. The treatment of primary cold urticaria is difficult, and the treatment of secondary cold urticaria needs to treat its primary disease. If the primary disease improves, urticaria will also improve. How to effectively prevent and keep warm? Wear hats and gloves on exposed parts of the body, such as face, neck and hands, in winter and when the cold wind blows. Other parts of the body should also pay attention to keep warm and avoid direct stimulation such as cold air and cold water. Like the patient mentioned above, he can't take a cold bath. Adjust your eating habits. Try to avoid eating fish, shrimp, crab, mutton and other high-protein and spicy, alcohol and other irritating foods in winter. Enhance physical fitness. Strengthen physical exercise to adapt to the changes of cold and heat. Drugs. Patients who have to go out in winter and can't completely avoid cold air stimulation need oral antihistamines to relieve their attacks. Through the above methods or measures, it is believed that the symptoms of patients with cold urticaria will be alleviated, or they will not attack, and they can spend the cold winter happily. The key to prevent this cold urticaria is to keep warm first. Wear hats and gloves on exposed parts of the body, such as face, neck and hands, in winter and when the cold wind blows. Other parts of the body should also be kept warm to avoid direct stimulation such as cold air and cold water. When washing clothes, you can add some hot water to the cold water. In any case, you should try to keep your skin from catching cold and keep it moist. Be sure to use hand cream. In addition, to resist itching after urticaria, don't scratch the skin, which can reduce the irritation to the skin. When itching is unbearable, you can use topical drugs such as Piyanping and Fusong, or see a doctor in time.

First of all, we should get into the habit of listening to and watching the weather forecast. When there is cold air, especially "cold wave", we should pay attention to keep warm and try to avoid going out and suddenly touching cold water.

Secondly, don't use strong alkaline soap for bathing in winter, and don't use other shower gels too frequently to avoid excessive sebum loss. In addition, we should take an active part in physical exercise to improve our body's adaptability to weather changes. For patients with cold urticaria, "desensitization therapy" can be used during the onset period, that is, washing your face with warm water is gradually changed to cold water, and after a period of adaptation, you can contact cold water or cold air to avoid allergic reactions. This method is simple and effective for most patients, but the water temperature should not be too low to feel cold, otherwise it may be counterproductive.

Finally, once suffering from this disease, patients should not grab the affected area, burn with hot water and avoid eating animal protein food and spicy food except for timely treatment in regular hospitals. If the condition is serious, you can take oral antiallergic drugs under the guidance of a doctor. For familial cold urticaria, there is no effective cure except symptomatic treatment at the onset.
