The sign of spring is what? Du Fu said [Nen Rui discussed carefully] and Su Shi said [Chunjiang Plumbing Duck Prophet]. If doctors say that spring is coming, the way to judge is that there are more patients with itchy faces, many of whom are still old acquaintances, and they have to [date] once a year in spring.
Arguably, patients with itchy skin have it all the year round, but these [old acquaintances] have some common characteristics:
1. Usually when spring comes, it breaks out suddenly.
2. The itchy places are mostly on the face and neck, or bare arms.
3. The rash is red and swollen from a distance. A close look may reveal some sesame-sized red pimples and/or some increased dandruff.
4. Easily jealous, itchy eyes and sneezing.
Why is this happening? The arrival of spring not only revives animals and plants that have been sleeping for a winter, but also increases the number of pollutants such as mold, dust mites, pollen, animal dander and the like floating in the air. These substances are common allergens and can induce inflammatory symptoms or allergic reactions in the contact parts of sensitive people.
Like many other allergic diseases, the ideal approach is to find out the allergens or inflammatory substances and then avoid contact with them. This is easier said than done. For example, allergy to pollen is widely found in the air every suitable season, especially outdoors. Even if you stay indoors and pay great attention to cleanliness, you cannot completely avoid other allergens in the room, such as dust mites and mold.
Allergy is a matter that affects the quality of life very much. If you have no knowledge in this field, it is right to seek help from a doctor in time. If you have a preliminary understanding of the cause of allergy, you can take some measures first:
1. Take a shower and change clothes and shoes in time after returning home from the outdoors. If there is a history of eczema and it worsens in spring, you can consider taking a 0.005% bleaching powder bath at the early stage of eczema deterioration. Apply ointment (hormone cream or calcineurin inhibitor) as soon as possible after bathing. Apply moisturizing cream after 15 minutes of application. Pay full attention to skin moisturization in daily life.
2. Use a clothes dryer to dry clothes and bedding after cleaning instead of hanging outdoors.
3. Pay attention to mattresses, bed beds, quilts, pillows, sofas, carpets, curtains, fluff toys… All places prone to dust accumulation should be cleaned regularly.
4. It is best to choose pure cotton high count bedding or special anti-mite bedding. Attention! Removing dust does not mean removing dust mites and mold. Proteins in dust mite feces are very common allergens and can be avoided if they cannot be prevented.
5. Close doors and windows, turn on air conditioner or air purifier.
6. Try to record the substances contacted, the environment and the food and drugs consumed within half an hour before each allergic attack. Symptoms of food-induced allergic reactions usually occur quickly. On average, it takes about 15 minutes. Some experiments show that all children with severe allergic reactions have symptoms within 30 minutes of contact, and most of them appear within the first 5 minutes.
If the above methods cannot relieve the allergic symptoms, That is to ask the doctor for help. In view of the domestic hospital level and even the doctor level varies greatly, it is suggested that the first choice is the allergy department of the teaching hospital closest to your residence or work place. They usually have a higher level of diagnosis and treatment, and also know more about the local common allergens, which is convenient for targeted examination.
Do a good job in relevant prevention, I hope everyone can enjoy a good spring scenery every year, and don’t let allergy become an obstacle to your date with spring.
Here are some questions and answers about allergy, hoping to be helpful to you.
What are the common examination methods in hospitals?
There are mainly three kinds: intradermal prick test, patch test and serum specific IgE test. In common skin allergic diseases in spring, intradermal prick test is usually sufficient to find allergens. If food allergy is considered, do not use patch test casually unless eosinophilic esophagitis is considered. Serum specific IgE detection can only detect allergens of quick-onset allergy, but not allergens of other types of allergy. Clinical correlation analysis should be carried out on the detected positive allergens. Symptoms can be relieved or disappeared after avoiding allergens, and only allergens with positive excitation tests can be related to diseases.
Can what medicine be used when allergy occurs?
First of all, if only the usual short-term external hormone cream for dermatitis is enough, Soft hormones are preferred. Soft hormones refer to hormones that are rarely absorbed by the whole body or can be rapidly decomposed into inactive products after being absorbed in the skin. The invention has the advantages that the absorption amount is very small, the high activity is only retained locally, the adverse reactions are greatly reduced, and the treatment index is greatly improved. Soft hormones are suitable for the elderly, infants and large areas. The existing soft hormones in China include mometasone furoate and fluticasone propionate.
Secondly, if the symptoms are not limited to dermatitis, There are also frequent attacks of sneezing, red eyes, itchy eyes and asthma. Then you may also need to add antihistamines (chlorphenamine, loratadine, cetirizine, etc.), read the instructions carefully before taking them, and understand the relevant contraindications and precautions, especially for infants, pregnant women and nursing women. If you sneeze frequently, you can wash your nose with normal saline. If you are jealous and itchy, it is recommended to go to the ophthalmology department, because jealous and itchy is not necessarily allergy, but also catarrhal conjunctivitis or atopic keratitis in spring, or even bacterial or viral infection, which should be identified first.
Can mothers restrict certain diets to prevent baby allergy?
The American Academy of Pediatrics, the Canadian Pediatric Association and the Australian Infant Feeding Guidelines all clearly point out: There is no evidence that limiting certain foods during pregnancy, lactation or infancy will be beneficial to the prevention of baby allergy. The measures with more evidence than restricting foods are, first of all, quitting smoking and preventing mothers and infants from being exposed to second-hand smoke and third-hand smoke contamination. The second is to avoid overflowing antibiotics and kill bacteria at any time. The immune system does not have the normal and slow process of contacting microbial antigens. Once it has strong contact several times in the future, it is easy to be allergic to common bacteria and microorganisms.
Do you want to quit spicy food for allergy?
Exogenous capsaicin can activate a receptor of skin sensory nerve, causing itching. It is best not to eat it if the skin itches. However, capsaicin can also reduce cough sensitivity, but it can be tried if there is chronic cough.
I used to have a dog. Can I prevent my child’s allergy if I don’t have it after pregnancy and childbirth?
As long as dogs are properly quarantined, dogs themselves will not increase the risk of infectious diseases and allergies of pregnant women and fetuses, unless the mother is already allergic to them. Even after the baby is born, dogs will not increase the risk of allergy and eczema. On the contrary, a large number of experiments have proved that dogs can also reduce the risk of allergic diseases.
Can allergy become chronic if it is not treated in time?
Yes. Improper treatment, especially scalding and scratching, can worsen and chronic symptoms. Although scalding and scratching can interfere with the transmission of itching sensation and temporarily relieve itching by generating pain, they can also release the analgesic substance serotonin (5-HT) in the brain, activate pruritus-specific neurons to aggravate itching sensation, and the more itching, the more scratching, the more itching, the more itching, the more itching, the more itching, the more itching, forming a vicious circle.
Is allergy fatal?
Severe allergic reactions can indeed lead to shock, cardiac arrest and even death. This is due to vasodilation and increased capillary permeability during allergy. The heart cannot adapt to this sudden change, resulting in cardiovascular failure (coronary artery spasm, schemic ischemia or infarction, malignant arrhythmia) and even cardiac arrest. The response is to inject epinephrine and hormones in time.
