Dermatosis recognition

Picture recognition of dermatosis, in medicine, dermatosis is a skin-related disease, such as leprosy, scabies, fungal diseases, bacterial skin infections and so on. Is one of the common and frequently-occurring diseases that seriously affect people's health. Let's share skin disease picture recognition.

Dermatology picture recognition 1 dermatology etiology;

General factors

(1) Race, sex, age: The incidence of skin diseases can be different due to these factors. For example, the incidence of basal cell epithelioma in white people is higher than that in colored people, and the incidence of connective tissue diseases such as SLE is higher in women than in men, and the incidence of skin tumors in middle-aged and elderly people is higher.

(2) Occupational and personal hygiene: harmful factors in the occupational environment can induce some skin diseases, such as cercarial dermatitis in agricultural labor. If personal hygiene is better, infectious skin diseases will be greatly reduced.

(3) Seasonal and social factors: With the change of seasons, the proportion of various diseases has also changed, such as fungal skin diseases in summer, frostbite and psoriasis in winter. Purifying the social atmosphere and vigorously preventing and controlling it throughout the country can reduce the spread of infectious diseases.

Second, common reasons

(1) Physical and chemical factors: pressure and friction, excessive local temperature change, radiation, light, thermal radiation, chemical reagents and other factors can all cause skin diseases.

(2) Biological factors: Insect bites, contact with certain plants, parasites and microbial infections are all common pathogenic factors, such as various viral skin diseases caused by virus infection.

(3) Diseases such as food: Some foods such as shrimp are easy to cause allergic diseases. Visceral diseases, local infections, and disorders of blood and lymphatic circulation can cause related skin diseases, such as itching in diabetic patients, eczema-like dermatitis caused by local infections, cyanosis and elephantiasis caused by circulatory disorders.

(4) Heredity: Some diseases have obvious family history, such as ichthyosis and albinism.

(5) Neuropsychiatric factors: Nerve injury can cause nutritional ulcer, and stress is closely related to stress, alopecia areata and chronic lichen simplex.

(6) Metabolic and endocrine factors: metabolic disorder can cause skin amyloidosis and xanthoma, while Cushing's syndrome is prone to acne and hirsutism.

In addition, some factors will aggravate skin diseases, thus affecting the outcome of the disease. Such as excessive scratching and secondary infection: scalding with hot water, washing with soap, and improper medication aggravate eczema; Exposure will aggravate photosensitive diseases.

Chinese medicine treats six kinds of dermatoses:

Coup for treating prickly heat: Make sure the skin is dry and clean, let the sweat drain smoothly, and wipe the sweat in time, especially on the armpit, neck, back and skin wrinkles. You can use some talcum powder. Ensure ventilated, cool and loose clothes.

Tips for treating dermatitis in summer: take orally and apply externally, boil water with barley red bean porridge or barley, and eat lightly to avoid cold, fat and spicy.

Tips for treating impetigo: keep your skin clean, take a bath frequently, change clothes and cut your nails. If you find a disease, treat it in time, don't scratch it, and discharge pus in time.

The best way to treat solar dermatitis: sun protection. Use sunscreen, hat and sunscreen clothing.

The best way to treat insect bite dermatitis: wear long pants. Huanglian ointment can be used externally.

The coup for treating tinea manus and pedis: wear cotton socks to ensure that the feet are dry and clean. In order to prevent infection, you can also soak your feet with drugs.

Picture recognition of dermatosis 2 What is the cause of dermatosis?

Common factor one: heredity

Some patients with skin diseases usually have a family history. In addition to monogenic diseases such as ichthyosis, more skin diseases are polygenic. For example, psoriasis has a high incidence in some families, and atopic dermatitis often has a family allergic history. Racial differences in some diseases, such as white skin with less melanin, are prone to sun damage, such as acute and chronic solar inflammation or actinic keratosis, and basal cell carcinoma is more likely to occur in exposed parts such as face.

Common factor 2: occupation

Some skin diseases are related to working conditions and working environment. For example, it is recognized that chemical plants are often exposed to chemicals, which is more prone to contact dermatitis, while farmers are allergic to plants when they contact plants. Paddy field dermatitis is generally only seen in farmers who often work in paddy fields.

Common factor 3: season

Most superficial mycoses such as prickly heat, pustule, tinea cruris and tinea pedis occur or worsen in summer when the weather is warm and the skin is wet and sweaty. Frostbite occurs in cold season, and insect bites such as mosquitoes and mites appear in summer and autumn, while ichthyosis and psoriasis are often aggravated in winter.

Common factor 4: age

Due to the different living conditions, environment and physiological characteristics of people of all ages, some diseases are easy to occur or only occur in specific ages. For example, infants are prone to hemangioma and infantile atopic dermatitis, children are more likely to see pustules and tinea capitis, young or middle-aged people are more likely to see rosacea and acne, and old people are more likely to see seborrheic keratosis, malignant tumors and systemic itching.

Common factor 5: climate

The theory of traditional Chinese medicine has brilliantly expounded the relationship between human diseases and natural climate, and Neijing put forward the theory that man grasps the qi of heaven and earth and "man corresponds to nature". A large number of clinical case observations and studies have proved that the onset of skin diseases and the aggravation or alleviation of their symptoms are closely related to the cold and hot changes of climate, seasonal changes, and even the time changes in a day. Patients with different diseases are also affected by climate factors.

Common factor 6: region

Common skin diseases are closely related to regions. Psoriasis, vitiligo, chapped hands and feet, ichthyosis, palmoplantar keratosis, chapped hands and feet, chilblain, systemic lupus erythematosus and neurodermatitis are the most common diseases in the north, while patients with chickenpox, herpes zoster, fungal infection, urticaria, dermatitis and eczema are the most common in the south. Psoriasis is more common in Shaanxi, Shanxi, Hebei, Henan, Inner Mongolia, Liaoning, Shandong, Sichuan, Hubei and Anhui.

Picture recognition of dermatosis III. Method for treating dermatosis

First, the skin itches.

Detailed explanation of the problem: when the weather is dry in winter, the skin will be dry and itchy, which makes people want to scratch. In winter, skin itching is generally not serious, and it may be confined to one place at first.

But gradually, it may lead to skin inflammation and scratches, eczema, desquamation, skin thinning, and even bacterial infection, which is often paroxysmal and affects sleep. Skin itching mainly occurs in the inner thigh, the outer leg and around the joints. Older people are more common, and people with dry skin are also prone to appear, often after taking a shower.

Symptomatic guidance: for itchy skin, don't scratch it if you feel itchy. Wear gloves when touching water or detergent, and don't burn yourself with hot water. When taking a bath, the water temperature should not exceed 32 degrees Celsius, and try to make the indoor air moist. When taking a bath, it is not advisable to use detergents with strong degreasing effect such as soap to avoid friction; Avoid spicy and irritating food, use drugs to relieve itching when necessary, and minimize emotional excitement in life. In addition, tea is rich in trace element manganese, which can protect the skin and advocate drinking tea in moderation every day.

Second, chapped hands and feet.

Detailed explanation: chapped hands and feet are also common skin diseases in winter. The skin suddenly suffers from cold wind drying, the secretion of sweat glands under the skin decreases, the keratin thickens and loses elasticity. Under the stimulation of skin injury or chemical substances, fingers, heels and soles become thicker and chapped easily. Eczema and chilblain on hands and feet can also be complicated. Walking can also lead to cracked feet, tingling, and even bleeding and infection. This disease is related to heredity, and people who lack vitamins are also prone to this skin disease.

Symptomatic guidance: for chapped hands and feet, pay attention to cold and warmth, protect hands and feet, and keep clothes, shoes and socks loose and dry. If there is chapped skin, it will take a long time to recover due to the thick cuticle of the affected area. You can apply skin anti-cracking agent or anti-cracking cream, and people with allergies should also supplement vitamins to reduce the contact between acid-base chemical products and the skin. The course of the disease is long, so you should eat more food to replenish qi and blood in winter.

Third, psoriasis.

Detailed explanation of the problem: psoriasis is easy to occur in winter, and the incidence rate in the north is higher. Because of the cold weather, psoriasis is a relatively big disease, which belongs to chronic diseases. It is divided into common type, pustule type, joint type and erythroderma type. Generally speaking, the common type is more common in patients, which can be local or systemic, showing patches of erythema and thick white skin peeling off layer by layer.

If the patient is psoriasis, it is not recommended that you handle it yourself. Be sure to go to the hospital for a definite diagnosis and careful treatment. "Symptomatic guidance: There are still some good suggestions for everyone in daily life.

There are many requirements for winter care of psoriasis. On the small side, we should talk about eating less spicy food and avoid bad habits, such as drinking a lot and smoking. When taking a bath, it is forbidden to wash, burn or directly expose the injured skin by hand, and pay attention to keeping the skin warm. The choice of intimate clothes should be pure cotton. Of course, in the process of encountering psoriasis harassment, a positive attitude is indispensable.

In the specific treatment, we should consult experts in regular hospitals, and it is not appropriate to choose irritating external drugs for recurrent skin lesions. When heavy metal drugs such as mercury-containing drugs are selected as the main components to stabilize skin lesions, it is not suitable for long-term large-scale use.

At present, it is believed that drugs can inhibit the excessive proliferation of cells, thus achieving the purpose of treating psoriasis. However, these drugs are often very toxic, and many patients can really improve their clinical symptoms after using them, but they often relapse after stopping taking them, and their condition is more stubborn and refractory than before. Clinically, some patients with severe psoriasis are often caused by improper medication, which not only endangers their lives, but also causes a heavy economic burden.
