chapped hands and feet
Introduction
Introduction to hand and foot cleft Hand and foot cleft palate is a disease of dry skin and linear fissures caused by various reasons for the skin of the foot. This disease is a common skin disease, which is more common in the elderly and women. It is often stimulated by mechanical or chemical substances. In addition, the winter climate is cold, the secretion of subcutaneous sweat glands is reduced, the skin is dry, the skin is thickened, and the elasticity is lost. Therefore, when the hand and foot exercise, it is prone to chapped. Chinese medicine believes that the occurrence of this disease is suddenly forced by the cold and wind, causing blood circulation, muscle loss, and skin sputum, causing chapped. basic knowledge Sickness ratio: 2% Susceptible people: no special people Mode of infection: non-infectious Complications: phlegm
Cause
Causes of hand and foot cleft palate
Physiological characteristics (15%):
The skin of the hands and feet, especially the palmar skin, has the following anatomical and physiological characteristics. The palms and palms of the hands and feet have no hair follicles and sebaceous glands. The stratum corneum is often protectively thickened, so that the skin is dry and hard to resist the erosion of various physical and chemical factors in the external environment, but Here, there is a lack of sebum protection, which causes local damage to split during the dry and cold season due to the action of local skin stretching. 1. The corner layer is thicker, especially in the palmar and heel areas, so it is prone to splitting. 2, palmar skin without hair follicles and sebaceous glands, so when the winter temperature is low and the humidity is small, the skin that lacks sebum protection is prone to chapped. 3, the above factors, coupled with the elderly, ichthyosis and keratosis, causing dry skin, the corner layer is more likely to thicken, under the influence of some external factors, it is more likely to develop.
External cause (35%):
1, physical: such as dry, friction, trauma, etc. can promote the onset. 2, chemical: acid, alkali, organic solvents, etc. dissolve sebum, the skin loses lubrication protection. 3, biological: such as fungi, such as infection, the skin hyperkeratosis, loss of the original protection.
Environmental factors (40%):
Hands and feet are exposed, especially hands, often exposed to various substances, easy to be affected by acid and alkali, fat solubility of organic solvents and infections caused by microorganisms such as fungi and bacteria. The skin of the palmar is dry, brittle and hard. The elasticity is reduced. On this basis, the cleft palate can occur due to the stretching and traction of the hand and foot activities. The elderly, ichthyosis, palmoplantar keratosis, keratotic ankle and the like are thickened due to thickening of the stratum corneum and the skin is dry and easier. The disease has occurred.
Prevention
Hand and foot cleft palate prevention
prevent disease
1, hand and foot cleft palate is a common skin disease in the elderly in winter, should eat more oil in the dry and cold season.
2, long course of disease or elderly patients should increase nutrition, appropriate to eat more pig liver, pig skin, lamb, donkey-hide gelatin, cod liver oil pills and other foods.
3, due to the cold and dry winter weather, the elderly sweat less, the skin is easy to dry and wrinkle, so special attention should be paid to the cold protection of hands and feet, often with warm water to wash, some oily skin care products, so as not to avoid Frostbite occurs and the cleft palate is aggravated.
4, usually in life should also pay attention to diet diversification, eat more fruits and vegetables, drink plenty of water, moderate intake of protein-rich foods, to maintain the skin's moisture and elasticity, so as to prevent the occurrence of hand and foot chapped.
Complication
Hand and foot cleft palate complications Complications
Can cause the body's qi and qi, the blood flow is not smooth, the extremities of the extremities are nourished, gradually become brittle, repeated friction or traction, and even splitting.
Symptom
Hand and foot cleft palate symptoms common symptoms heel cracked skin dry soles dry cracked skin splitting hands peeling
More common in adults and the elderly, the affected area is dry, rough, thick, chapped, chapped and more along the direction of the skin, the skin lesions occur in the fingers, palms, palms, heels and ankles, the edge of the skin and other stratum corneum Thick and often rubbing parts, mostly in autumn and winter, the sky is getting warmer, after slowing down, according to the degree of cleft palate, it is divided into three degrees:
Once: the affected area is dry and cleft, but only the epidermis, no bleeding, pain, etc.
Second degree: The affected area is dry and the fissure is as deep as the dermis with mild tingling, but no bleeding.
Third degree: The affected area is dry and the fissure is deep to the deep dermis and subcutaneous tissue, often accompanied by bleeding, pain or tenderness.
Examine
Hand and foot cleft palate
According to the objective manifestations and subjective symptoms of the cleft palate, the diagnosis is not difficult and no additional examination is needed.
Diagnosis
Diagnosis of hand, foot and cleft palate
diagnosis
According to the cracks that occur in the depths of the palm of your hand, the skin is dry, hard, brittle, with reduced elasticity and varying degrees of pain, and it can be diagnosed in autumn and winter.
Differential diagnosis
The disease should be differentiated from the following diseases.
1, scaly keratinized hand and foot sputum: summer heavy winter light, A can be affected at the same time, fungal microscopic examination.
2, palmoplantar keratosis: for congenital diseases, starting from the onset of childhood, the family often have the same symptom patients, bilateral palmar skin hypertrophy and significant.
1, hand and foot
Hand, foot and ankle can also cause cracking pain due to scratching, but the hand, foot and ankle have the following characteristics:
1 often limited to one side of the palm or sputum, between the fingers (toe), rarely limited to the heel.
2 The primary damage is papules and blisters.
3 often itchy, very little pain, sometimes chapped all year round, not necessarily heavy in summer or summer, but sometimes more severe in summer.
4 often with toes, nails are concomitant.
5 often find fungus in the skin lesions.
It should be pointed out that sometimes the hand and foot cleft palate can be complicated by hand and foot, and the two diseases can be mutually causal. According to the survey, the concurrency rate is 30% to 85%.
2, hand and foot eczema
Sometimes hand and foot eczema can cause cracking pain due to itching, but eczema such as acute or subacute, primary damage to erythema, papules, blisters, etc., often with itching, if it is chronic, it is often located in the palm of the hand and involves the hands and feet The back, and more with thick skin and itching, so the two can be identified, hand and foot cleft palate can coexist with hand and foot eczema, coexistence rate of about 1, 4%.
3, ichthyosis
Sometimes it is easier to split the hands, feet and feet on the basis of ichthyosis, especially when the ichthyosis is aggravated in the cold season. The concomitant rate of the two diseases is 24% to 47%.
4, palmoplantar keratosis
It is a congenital disease, which is easy to cause cleft palate due to hyperkeratosis. However, palmoplantar keratosis does not necessarily form cleft palate in winter and autumn, and sometimes it can occur all year round. The concomitant rate of the two diseases is 2% to 4%.
