What is ectopic dermatitis, skin is too dry, the guy also coated moisturizing cream turned out to be suffering from ectopic dermatitis! Moisturizing cream should be coated non-stop, otherwise the whole body skin dry cracks, dry pain, flaking. Yesterday, in Jiangxi Provincial Hospital of Traditional Chinese Medicine dermatology, a 20-year-old boy in pain to the doctor for help. Chen Li, chief physician of the department, said the patient suffered from atopic dermatitis, this skin disease dry weather easily attack, but so severe in the clinic is rare. Li Bing, chief physician told reporters that the patient suffered from atopic dermatitis, the disease is a genetic predisposition to an allergic reaction to the skin disease, most patients from infantile eczema recurrent episodes of prolonged, 70% of the patient's family has a history of allergy, asthma, or allergic rhinitis and other genetic allergies, is a chronic, recurrent, itchy, inflammatory characteristics of the skin disease. Studies have shown that 60% to 90% of patients are affected by seasonal factors, such as dry weather, cold stimulation, coupled with less sun exposure time. Pathogenesis of atopic dermatitis: Atopic dermatitis (Afodic dermafifis) is also known as atopic eczema or genetic allergic eczema. The name atopic dermatitis was first proposed by Wise and Sulzberger in 1933. And the term "atopic" for coca (coca) in 1925 first initiative, its meaning is: the patient or family members prone to asthma, grass fever, allergic rhinitis, urticaria, eczema and other diseases history; allergic to foreign protein; patients with blood green in lgE value increased; patients with blood green in eosinophilic leukocytosis. [Etiology and pathogenesis] The etiology and pathogenesis of atopic dermatitis are complex and have not been fully elucidated to date. One of the causes of the disease is hereditary allergic qualities that attracts particular attention, and the sensitivity of the patient and his family members to certain substances inside and outside the body is often higher than that of normal people. According to statistics: both parents have "atopic" manifestations of about 70% of the offspring can also be "atopic"; if only one of the parents see "atopic", then roughly half of the children can be seen to have "atopic". "If only one parent is atopic, about half of the children will be atopic; however, in 40% of patients with atopic disease, the parents are not found to be atopic. Foods, especially protein foods, are the most common allergens in the disease. In addition, various substances inhaled through the respiratory tract, such as house dust, pollen, animal hair and dander, should not be ignored. It is often thought that food allergy seems to be the main cause of allergy in infancy, but inhalant allergy is more common after childhood. In addition to the above, seasonal changes in climate, mental stress, strong scratching stimulation, sweating, etc. are all prone to exacerbate the condition of the disease. The pathogenesis of atopic dermatitis can be both allergic and non-allergic. Many of these issues have not yet been unanimously concluded, and some of them are contradictory. This needs to be practiced in the future and actively explored and researched. [Clinical manifestations] Atopic dermatitis can be divided into three stages: infancy, childhood and adulthood. I. Infantile atopic dermatitis The clinical manifestations of this type are the same as those of infantile eczema, and it is difficult to distinguish between the two (see the second section of this chapter for details). Children can be around 2 years of age, the symptoms gradually alleviate, or even self-healing. Some of these patients may relapse again in childhood or adulthood; some patients may continue to develop into childhood until adulthood. Second, childhood atopic dermatitis This type is mostly seen in infants after eczema, to 6 ~ 10 years old when the re-emergence of eczema; can also continue to evolve from infancy; there are a few patients to the beginning of the onset of childhood. Atopic dermatitis in childhood can be divided into two types, namely, eczema and itchy rash. The eczema type occurs more often on the limbs, especially the elbow and popliteal fossa. The lesions are similar to subacute or chronic eczema in adults. The most common are dense papules, papules and blisters, often fused to each other in patches, some of which are mossy. The itchy rash type occurs on the extensor sides of the limbs and behind the back, the rash manifests itself as a generalized sparse distribution of rice to soybean-sized papules, the damage is dry, and the old lesions are small and hard. The lesions are scratched and often accompanied by localized lymph node enlargement. Atopic dermatitis in childhood is characterized by itchiness, especially in the form of itchy rashes, which can be secondary to bacterial infections due to scratching. The course of the disease is chronic, often repeated episodes, can be gradually cured or development of adult atopic dermatitis. Third, adult atopic dermatitis patients in this period have a history of infancy or childhood atopic dermatitis. Skin lesions usually occur in the limbs flexion, neck, can also occur in the forehead, eyelids, the back of the hands and other places. Occasionally, there are cases of generalized eruption. The lesions are more limited, and the rash is often erythematous or reddish papular, with fine scales and hyperpigmentation on the surface. The affected area is very itchy, often due to intense itching and secondary infection. The course of the disease is chronic, the nature of the disease is sometimes mild and sometimes severe, and ultimately can be gradually cured. Typical patients with atopic dermatitis go through the three stages of manifestation described above, namely infancy, childhood and adulthood. However, atopic dermatitis may not occur in infancy, but rather in childhood or adulthood. Some patients only have atopic dermatitis, and some patients may have rhinitis in addition to other allergic diseases, such as bronchial asthma, urticaria, allergic rhinitis and so on. Individuals can be accompanied by cataracts and retinal detachment, in addition, patients with this disease are often accompanied by dry skin, follicular keratinization, increased palm lines and the phenomenon of white skin scratch. Atopic dermatitis is prone to bacterial infections and viral skin diseases. [Lab Tests] Eosinophilic leukocyte counts are increased in the blood of patients with this disease; lgE is elevated in the patient's blood serum and can be measured by the passive transfer test; skin tests with specific antigens can be positive with an immediate reaction. [Diagnosis and differential diagnosis] According to the clinical manifestations of infantile atopic dermatitis can be diagnosed, while other stages of atopic dermatitis, must be combined with auxiliary examination to make a diagnosis. The key to differentiating this disease from infantile eczema lies in the fact that the former has "atopic", while the latter does not. Atopic dermatitis should also be distinguished from infantile seborrheic dermatitis, which usually begins in the third to fourth week of life. The rash is erythematous with oily scales and lacks polymorphic features. It occurs on the head, and may also involve the eyebrows, nasolabial folds, behind the ears, and the neck. Self-awareness of light itch or not itch. Prognosis is good, often within a few months can be cured. Atopic dermatitis of the soup family focus on the following principles: 1. skin is inflamed, do not soak in the soup. 2. try to choose a neutral spring. 2. Try to choose neutral or weakly acidic springs to soak. 3. 3. do not soak for too long, every 15 minutes to get up and take a rest. 4. 4. after the soup must be rinsed with water, pay attention to not let the spring water residue in the skin folds, special attention to the toe seam, finger cracks, navel, armpits and other places. 5. Do not rub your hands hard to scratch the skin before and after soaking in the soup. 6. If the skin feels very dry after soaking in the soup, you should immediately apply a thin layer of petroleum jelly or other lubricants. [Treatment] Try to find the cause of the disease and remove it, but it is difficult; focus on adjusting the diet, do not overfill, avoid eating allergenic items, such as feeding cow's milk, egg white, citrus, etc.; breastfeeding mothers to eat a light diet is preferred, shellfish and alcohol should be prohibited; try to minimize the external adverse stimuli, such as scratching, topical soap, hot water scalding, etc.; clothing should be more loose, light, soft, avoiding to wear woolen products or nylon fabrics; This product is contraindicated in cowpox, avoid contact with the newly planted cowpox or herpes simplex patients, in order to prevent the occurrence of cowpox-like rash or chickenpox-like rash. I. Internal therapy (a) antihistamines: 1 to 2 kinds of antihistamines can be used internally, atopic dermatitis in infancy can be 0.2% benzylamine syrup, 2 to 4mg/kg .d, divided into three times. (ii) sedative: to strengthen the effect of itching, can be applied to the sedative, commonly used luminal (pediatric dose of 0.5 ~ 1mg. times) or hibernation spirit, (pediatric dose is 0.5 ~ 1mg/kg., times). Often used in combination with antihistamines, may improve the efficacy. (C) digestive drugs: discretionary yeast tablets, lactasexan, vitamin B1 and other oral to help digestion, to promote the improvement or recovery of the disease is beneficial. (D) Corticosteroids: only for stubborn, severe adult atopic dermatitis, the use of small doses of short courses of treatment, such as prednisone 20-30mg / day, can be more satisfactory results. For other stages of atopic dermatitis, the use of corticosteroid therapy is not advocated. (E) Antibiotics: If there is secondary bacterial infection, it is necessary to apply antibiotics, such as madicillin and erythromycin, but it is better not to use penicillin, because the incidence of penicillin allergy in patients with this disease is higher, so it should be emphasized. (F) Traditional Chinese medicine treatment: refer to Section II of this chapter. Second, external therapy Symptomatic disposal, treatment and usage are the same as eczema. Third, atopic dermatitis should pay attention to matters when soaking soup 1. skin is inflammation should not be soaked in soup. 2. 2. try to choose neutral or weakly acidic spring quality hot springs to soak. 3. 3. Don't soak for too long, and take a break every 15 minutes. 4. 4. after the soup must be rinsed with water, pay attention to not let the spring water residue in the skin folds, special attention to the toe seam, finger cracks, navel, armpits and other places. 5. Do not rub your hands hard to scratch the skin before and after soaking in the soup. 6. If you feel very dry skin after soaking in the soup, you should immediately apply a thin smear of petroleum jelly or other lubricants. Knowledge source: /
