chapped hands
Introduction
Introduction to hand cracking Blister, commonly known as hand crack, is a type of cleft palate due to damage to the oil film on the surface of the skin, dry skin, and loss of elasticity. Hand dry cracking mainly occurs in winter, poor blood circulation, lack of water in the body, dry weather and frequent washing and cooking caused by dehydration of the skin. Therefore, attention should be paid to the maintenance and warmth of the hands. basic knowledge Sickness ratio: 2% Susceptible people: no special people Mode of infection: non-infectious Complications: phlegm sore bacterial infection
Cause
Hand chapped cause
Human Factors
Regular laundry and cooking cause dehydration of the skin, causing chapped.
Weather factor
In cold weather, blood circulation is poor, skin elasticity is reduced, and it is easy to cause hand cracking.
Exposure to the sun for a long time can also cause hand cracking.
Physiological aging
Older people have slower metabolism, more dead cells, fewer newborn cells, poor skin elasticity, and prone to hand cracking.
Metabolic disorder
Some women cause metabolic disorders after childbirth and form a hand crack.
Nutritional factors
Lack of vitamin A and vitamin E can cause hand cracking. You can drink some boiled water, juice, milk, soy milk and other fluids to nourish Yin and moisten. Make up for the loss of moisture.
eczema
Eczema can cause hand cracking.
Fungal infection
The symptom of the keratinized thickening handcuffs (goose palm) is also hand cracking.
The occurrence of hand and foot cleft palate is related to the anatomical and physiological characteristics of local skin and various external factors, and also has a certain relationship with the general condition. Anatomical and physiological characteristics of the hand and foot are extremely thick in the palm and heel, which can be as thick as 100 layers. The keratinocytes are irregularly arranged, and these parts are free of hair follicles and sebaceous glands, which keeps the local skin moisture and sebum on the skin. Run is subject to certain restrictions, when the external factors affect, it is prone to skin splitting.
Prevention
Hand crack prevention
prevention
1. 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, because the winter climate is cold and dry, sweating is less, the skin is easy to dry and wrinkle, so you should pay special attention to the cold and warmth of your hands, often with warm water to wash, and some oily skin care products (such as glycerin), 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 hand cracking.
5. Strengthen physical exercise and strengthen the conditioning of metabolism.
6, pay more attention to some healthy diet.

It is easy to cause chondrocytes and bacterial infections.
Symptom

Handcuffs
Blister scaly type -------- Onset is mostly a single case, starting with a certain part of the palm, especially the palm, index finger and ring finger palm, side and root, starting with a needle-sized blisters, wall Thick and shiny, containing clear liquid, blister gathered or scattered in groups, consciously itching, blister dry after desquamation and gradually spread to the surrounding to form a ring or multiple ring damage, clear edges, chronic disease, lasting for many years, until It involves all the palms and spreads to the back of the hands and nails, even the opposite side of the palm. Sometimes vesicles can be secondary to infection to form pustules.
The keratinized thickening type-------- is mostly developed from the blister scaly type. The patient has a history of many years, often involving both hands, no obvious blisters or ring-shaped desquamation of the skin lesions, and diffuse redness on the palm surface. Thick, deep skin, rough skin, dry and desquamation, easy to split in winter, deep and bleeding, pain, unbearable, affecting activities, promoting palm keratinization and thickening factors in addition to dermatophytes, but also long-term Scratch, laundering, soap, detergent, various chemical and solvent irritations, and inappropriate treatment.
Eczema
The rash is characterized by dark erythema, the surface of the skin is dry and rough, and it can also be hypertrophic, often accompanied by cleft palate in winter, and varying degrees of itching.
Hand cracking for other reasons
At the beginning of the onset, the skin is dry, the keratinization is thickened, the skin lines are obvious, and cracks appear along the skin lines. Severe cases can be deep into the skin, bleeding, conscious pain, more obvious when active. A purulent infection can occur if bacteria invade.
Examine
Hand cracking check
According to the objective performance and subjective symptoms of hand cracking, the diagnosis is not difficult and no additional examination is needed.

diagnosis
According to the objective manifestations and subjective symptoms of hand cracking, diagnosis is not difficult.
Differential diagnosis
The disease should be differentiated from the following diseases.
1. Squamous keratosis type hand, foot, summer, heavy winter, A can be affected at the same time, fungal microscopic examination.
2. The palmoplantar keratosis is a congenital disease. It begins to develop from an early age. There are often patients with the same symptoms in the family. The keratosis of the bilateral palmar skin is significant.
Hand, foot and ankle
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 2.4%.
