sebum deficiency
Introduction
Introduction to sebum deficiency Sebum deficiency (eatatosis) The reduction or lack of sebaceous gland secretion causes dry skin, also known as dryskin, often a simple ichthyosis-like manifestation. The onset begins in children and continues or tends to increase with age. Summer can be improved. Environmental changes such as low humidity, cold air, dry heat and hair can all aggravate the condition. basic knowledge The proportion of illness: 0.005% - 0.015% Susceptible people: no special people Mode of infection: non-infectious Complications: Coin-like eczema
Cause
The cause of sebum deficiency
Systemic disease (30%):
Such as mucinous edema, diabetes, diabetes insipidus, uremia, etc., some skin diseases, such as ichthyosis, vitamin deficiency skin disease, leprosy, xeroderma pigmentosum, scleroderma, radiation dermatitis, skin atrophy.
Age factor (20%):
For example, in the elderly, sebaceous gland function is reduced due to physiological reasons, and sebum secretion is reduced to make the skin dry. Since sebum is mostly secreted by sebaceous glands, a small part is formed by keratinization of epidermal cells, and sebum forms an emulsion with epidermal cells and external water. Leather mask, if soap or detergent is used on the body surface, the water-soluble substance on the skin surface will be destroyed, and the skin will be dried.
Occupational factors (10%):
Such as engaged in the production of alkaline substances, soap, washing powder and other workers.
Prevention
Sebum deficiency prevention
The cause of this disease is not clear, so it is impossible to prevent the cause. However, for secondary sebum deficiency, prevention should be performed on the primary to reduce complications. Actively treat related systemic diseases and skin diseases, and strengthen the protection of occupational diseases. Actively treat related systemic diseases and skin diseases, strengthen the protection of occupational diseases, and avoid the use of alkaline substances.
Complication
Sebum deficiency complications Complications, coin-shaped eczema
Chronic or coin-like eczema-like mossy changes due to rubbing.
Symptom
Symptoms of sebum deficiency common symptoms itching skin dry scaly nutrition disorder blood deficiency
Limited or extensive dry skin, small cracks, lack of sebum, often itching, attached porphyria, bran-like scales, sometimes painful, more winter, no flushing and inflammation, caused by friction, causing chronic or coin-like eczema Moss-like changes, scaly increase like ichthyosis vulgaris, the most prominent parts of the dry are the calf and forearm extension, the arm and wrinkles are rarely affected, patients often have a positive family history, twins have a higher co-occurrence rate, have a genetic allergy The quality of the person is particularly obvious.
Examine
Examination of sebum deficiency
Clinical skin examination: limited or extensive dry skin, small cracks, lack of sebum, often itching, adhesion of Philippine thin bran-like scales, sometimes painful, more winter, no flushing and inflammation. Due to rubbing, it causes chronic or smoky eczema-like mossy changes, and scaly increases like ichthyosis. The most prominent areas of dryness are the calf and forearm extension, and the arms and wrinkles are rarely affected.
Pathological examination: visible tissue sebaceous gland deficiency or hypoplasia.
Diagnosis
Diagnosis and identification of sebum deficiency
diagnosis
According to the above clinical manifestations, it is generally not difficult to diagnose. Generalized sebum deficiency may be related to thyroid disease or kidney disease. If a ichthyosis-like rash occurs in adults, it may indicate the potential of lymphoma, secondary to scratching and friction. Inflammation changes.
TCM pathogenesis and syndrome differentiation: the disease is a deficiency of congenital endowment, loss of blood deficiency or exogenous heat evil, or excessive sweating, injury and dryness, but also due to loss of blood in the blood, or misuse of sweat medicine, injury and death Liquid, or nutritional disorders, or internal resistance of blood stasis, etc., so that the blood can not moisturize the skin, and dry and rough, dry and unsatisfactory.
Differential diagnosis
Should be distinguished from primary eczema-like dermatitis.
