After a child with eczema is born, it is not enough to simply apply some eczema ointment. It took you five years to come to this conclusion with children. Applying ointment alone can't solve the fundamental problem. You ask your child whether eczema is allergic or eczema. The answer is that eczema caused by allergies is a symptom and allergies are the cause. Just like a cold, a cold is a symptom caused by a bacterial or viral infection.
When children have allergic diseases, in fact, many children are allergic, which can be controlled in the lightest state and will not develop into serious allergic diseases. However, few of us can solve the problems of early identification, early conditioning and early correct nursing. Therefore, it can be said that every child with severe allergies has a considerable relationship with his parents' cognition.
Eczema in children is an allergic skin symptom, which is usually called allergic skin symptom. The main reasons are intolerance or allergy to food, inhalation or contact. Children with eczema have red skin and rash at first, then rough skin and desquamation. Touching a child's skin is like touching sandpaper. Both damp and heat can aggravate eczema rash and itchy skin. The cause of eczema is complicated, and the most important factor is allergic factors, so children with family history of allergic constitution are more likely to suffer from eczema. The main reasons are intolerance or allergy to food, inhalation or contact.
Symptoms of eczema in children
Long-term eczema with itchy skin leads to pigmentation and mossy thickening of the skin. Eczema can be divided into acute, subacute and chronic stages according to the appearance of rash at the time of onset. The initial damage is dense miliary papules, papules or blisters on the basis of erythema. After the bubble bursts, it forms a rotten surface with serosity oozing and scabbing. Acute eczema can be turned into subacute or chronic eczema if it is not handled properly. If the treatment is timely and proper, it can gradually improve, but it is easy to relapse. In severe cases, a large area of erythema can appear, which is a group of papules, papules, blisters and erosive exudates with thick scabs on the surface, and can also extend to the whole head and face or head and neck. Erythema papules, papules, blisters and self-conscious itching appeared around the lesion. There may be abrasions and scabs, pus oozing under the scab, small pustules at the edge, swollen local lymph nodes and tenderness. There may also be parallel erythema, papules and blisters caused by near or far scratching.
Have a history of exogenous diseases or unclean diet. The lesions are polymorphic, with erythema, papules, blisters, erosion, exudation and scabbing. It is often caused by eating fish, shrimp, crab, mutton, coffee, wine and spicy food. Skin lesions are mostly localized, with clear boundaries, dark red or grayish brown, and covered with scales. Chronic eczema leads to rough and thickened skin, obvious skin wrinkles, lichenoid transformation, or excessive keratinization and chapped inflammatory plaques. There is no specific change in laboratory examination, and blood eosinophils may increase. Skin patch test has some limitations.
Endogenous, exogenous, skin barrier function and Staphylococcus aureus infection are the four inducing factors of eczema in children.
Exogenous inducing factors of eczema: food allergy: the main food allergen of children with eczema allergy under three years old is eggs >: milk >; Soybean > wheat >; Peanuts.
Endogenous inducing factor of eczema: intestinal mucosal barrier dysfunction: food allergy first occurs in the intestine, because the onset site of eczema in children is in the skin, so it is difficult to connect with intestinal function, but intestinal mucosal barrier function is the first site to induce food allergy in infants, and because this cause has not attracted the attention of medical institutions and parents, the treatment of eczema in children is mostly focused on the treatment of rash, because the pathogenic factors of eczema in children cannot be fully grasped and adjusted, which leads to
Causes of skin mucosal injury in eczema: damage of skin mucosal barrier (HDM_ protease): increase of cytokines secreted by keratinocytes. The human skin barrier is divided into four epidermal parts:
The first layer is microbial barrier (also called bacterial barrier). When people's skin is observed under a microscope, they are all bacteria. Therefore, it is not recommended that children with eczema excessively clean their skin. Many modern new lifestyles are destroying the microbial barrier of human body.
The second layer is the physical barrier
The third layer is a chemical barrier
The fourth layer is the immune barrier.
Staphylococcus aureus infection: This is basically ignored in the treatment of infant eczema at present, which is also the main reason for the prolonged development of infant eczema in the middle and late stages. It is also inseparable from the skin mucosal injury of eczema, because the long-term itch-scratch-itch-scratch of eczema children's skin forms a vicious circle, which is the main reason why Staphylococcus aureus infection stimulates the skin keratinocytes to secrete cytokines. Therefore, the baby's eczema will have moss-like thickening and blackening in the later stage.
Effect of eczema on the quality of infant;
Because skin eczema has long plagued children's growth and development, there is also a stubborn rash, which can appear in any part of the child's body. Eczema of head and face and intractable eczema of limbs have become the most typical rash types of eczema in school-age children aged 2-6 years. The biggest disease feature of eczema is itching, which can be called itching in medicine. Eczema in children seriously affects children's sleep and upcoming campus life. With the growth of children, the long-term trouble of eczema leads to the pain and depression of children and the whole family, and also leads to the loneliness of children.
Proportion of eczema in children of all ages:
(<6 months) Early infantile eczema: Eczema occurred about 30 days after birth, with a clinical incidence rate of 53%, mainly due to milk protein allergy;
(6- 12 months) Mid-term infant eczema: The clinical incidence rate is 23%, and food allergy is still the main cause, but there may be many allergens. This stage is the stage when babies begin to add complementary food, and it is also a very allergic period;
(> 12 months) Late stage of eczema in children: the clinical incidence rate is 25%, and it is easy to develop into atopic dermatitis, and the course of disease is easy to continue into adolescence.
The new progress in the basic treatment of eczema in children (anti-allergic probiotics+skin moisturizing emollient+skin antibacterial) is the basic treatment to reduce the use of skin hormones in eczema in children.
Early diagnosis, avoid contact with allergens.
2. Intestinal immunity of anti-allergic probiotics in children eczema: In view of the pathogenic factors of children eczema: the increase of IgE in allergic constitution-skin damage and infection-skin barrier dysfunction, which is closely related to the occurrence and development of eczema, Kang Minyuan's anti-allergic probiotics experts summarized three necessary conditions for the treatment of eczema:
First, the research results of Kang Minyuan's anti-allergic probiotics on the endogenous induced etiology of eczema in children and the influence of eczema in children after recovery.
Skin flora and eczema: Anti-allergic probiotics have certain preventive and therapeutic effects on eczema in children.
The research results of microorganisms and bacteria in allergic reactions have attracted the attention of clinicians. Many papers have been published on microecological research results such as microorganisms and allergic diseases, intestinal microorganisms and childhood asthma, respiratory microorganisms and childhood asthma, the preventive and therapeutic effects of antiallergic probiotics on childhood asthma, and antiallergic probiotics and eczema and urticaria. For allergic diseases, it is no longer at the therapeutic level of antiallergic drugs and hormone atomization. Man is a "superorganism", and some refractory diseases are expected to make therapeutic breakthroughs in the study of human organisms in the near future. The human genome and microbiome have the same function, affecting the immune, nutritional and metabolic processes of human body. Professor Wang Zhiyao of national cheng kung university Allergy and Clinical Immunology Research Center in Taiwan Province conducted a clinical experimental case study. Through the influence of allergic probiotics on the occurrence and development mechanism of allergic diseases immune system, an antiallergic nutritional therapy of antiallergic probiotics was created. Supplementing Kangminyuan antiallergic probiotics can: regulate the stable state of respiratory tract microbial flora. Adjust the homeostasis of intestinal microbial flora and improve the allergic mechanism of intestinal food protein; Adjust the allergen-specific IgE pathway mediated by intestinal microflora and inhibit the production of allergen-specific IgE antibody, because Kangminyuan anti-allergic probiotics can increase the diversity of intestinal microflora, regulate the activation of TH cytokines, inhibit TH2-type response, enhance TH 1 type immune response, up-regulate immune cells and accelerate the repair of skin and mucosal barrier function.
Second, it is very necessary for anti-inflammatory treatment: external use of Baiduobang ointment to fight the infection of damaged skin; Among the patients who take Kangminyuan anti-allergic probiotics to relieve eczema and adjust their allergic constitution, we made a survey on eczema patients. Few people know about anti-inflammatory treatment and its significance, whether it is intractable eczema in adults, atopic dermatitis in children or eczema in infants. International studies on the epidermis of patients with eczema and other skin diseases show that patients with chronic skin eczema are complicated with sensitive bacterial infections such as Staphylococcus aureus on the skin surface, but most eczema patients do not know how to use anti-inflammatory treatment. It is suggested that eczema patients can use Baiduobang ointment for effective local anti-inflammation.
Third, the importance of skin moisturizing cream: reduce bathing, eczema will get worse when it is wet. Moreover, the congenital skin barrier function of eczema baby is not perfect, and the synthesis of sebum layer of skin is blocked. Bathing should be reduced and skin emollients should be used to protect the skin.
A large amount of urea moisturizing cream can resist dryness and restore skin barrier function. The emollient containing medicinal urea is better, and 10% urea cream is beneficial to enhance the skin barrier function of patients. Moisturizing emollients can save about 50% skin hormones when treating eczema. You should use emollients to protect your skin at least twice a day.
