2 Introduction of prevention and treatment methods of dermatosis
Dermatosis refers to skin-related diseases, which means that the shape, structure and function of skin (including hair and nails) change after being affected by internal and external factors, resulting in pathological process and corresponding clinical manifestations. The incidence of skin diseases is very high, and most of them are mild, which often does not affect the lives of patients, and many of them are difficult to cure. It is a disease that causes great physical and mental pain to patients and affects the quality of life. The most obvious diseases are itching and skin appearance changes.
Common skin diseases include psoriasis, vitiligo, herpes, rosacea, impetigo, suppurative infection, scabies, scars, ringworm, ichthyosis, bromhidrosis, acne, folliculitis, alopecia areata, infantile diaper rash, corns, freckles, herpes, acaroid dermatitis, eczema and urticaria.
Psoriasis, commonly known as psoriasis, is a common chronic inflammatory skin disease, which is easy to recur. The characteristic lesions are red papules or plaques covered with layers of silvery white scales. Young people suffer the most, men are heavier than women, and the north is heavier than the south. It is easy to occur or aggravate in spring and winter, and it is more relieved in summer and autumn. Its etiology and pathogenesis are not completely clear. It is found that the onset of the disease is related to genetic factors, streptococcal infection, abnormal immune function, metabolic disorder and endocrine changes. There are four types in clinic: common type, pustule type, erythroderma type and arthropathy type. Psoriasis vulgaris is the most common and its condition is mild. The disease is chronic and easy to recur after cure.
The above is about some knowledge you want to know. In fact, skin diseases are caused by individuals, and some are unsanitary. Many times it won't hurt life, but it will make people feel bad. In the face of patients with skin diseases, we should look at them with normal eyes. In fact, they are nothing special, just a disease.
Is the effect of oral anti-inflammatory drugs for dermatosis good?

What are the factors that lead to skin diseases?
There are many reasons for skin diseases, which can be simply divided into four categories: inflammation, dryness, infection or itching caused by internal diseases. The most common cause is itching caused by skin inflammation, which is called eczema. For example, children's atopic dermatitis often causes extreme itching of the skin, and even causes allergic children to sleep and eat badly; Fatty dermatitis often causes scalp and facial itching in elderly patients; Housewives with rich hands, coin eczema, lichen planus, drug allergy, urticaria, etc. Are they all itching caused by skin inflammation?
Dry skin is also one of the main causes of itching. With the increase of age, sebaceous glands will gradually degenerate, which often makes the skin moisturizing ability of middle-aged and elderly people worse than before. The skin is dry and peeling, and even chapped and bleeding, especially in the lower limbs. Drying itself can cause itching discomfort, because the winter climate is very cold, which is more common in winter itching caused by drying. This kind of itching caused by dry crack should avoid taking a bath with too hot water, and use moisturizing emulsion as appropriate to improve the symptoms.
Beriberi and itching of crotch caused by fungal infection of skin are more common in summer. Skin scabies infection is common in military, boarding schools and other crowded places, which often causes extreme itching at night until the patient scratches and bleeds. What worries me most is that there are some systemic diseases, initially manifested as itchy skin. For example, diabetes, renal dysfunction, cholestasis, hyperthyroidism or insufficiency, or some blood diseases, malignant tumors, etc., will cause unexplained skin itching.
Examination and diagnosis of allergic dermatosis
I. Physical inspection
1, slide pressure diagnosis method: press the slide hard on the injury 10 ~ 20 seconds, and the color of inflammatory erythema and hemangioma can disappear.
2, skin scratches: scrape the skin with a blunt instrument, if there is wind in the scratch, it is called skin scratch positive.
3. Sensory examination: including temperature perception, touch and pain.
4. Filter ultraviolet examination: For example, favus's hair shows dark green fluorescence, while tinea versicolor shows bright green fluorescence.
5. Examination method of spinocytolysis (Nissl's sign): It is positive when the blisters spread around, the normal skin is pushed away, and the skin with normal appearance between blisters is wiped off.
Second, the laboratory inspection
1. Histopathological examination of skin: Some allergic skin diseases have their unique pathological changes, which can be used for diagnosis and differential diagnosis.
2. Skin test.
3. Biological examination: the examination of dermatophytes, leprosy bacilli and rash insects is helpful for the diagnosis of corresponding allergic skin diseases.
