Skin disease caused by lacquer

Introduction to skin diseases caused by paint Skin disease due to contact with paint. Lacquer is a skin disease caused by an allergy to lacquer or lacquer and belongs to contact dermatitis. At the first episode, the majority of the illness is heavier, and later, the symptoms are alleviated. However, a small number of patients become heavier and heavier, even when they smell the paint or see the paint (may not be exposed to its volatiles). Onset. basic knowledge The proportion of sickness: the incidence of decoration workers is about 0.5% - 0.7% Susceptible people: no specific population Mode of infection: non-infectious Complications: folliculitis

Causes of skin diseases caused by paint

(1) Causes of the disease

Most lacquer dermatitis is caused by direct contact with paint or lacquered items.

(two) pathogenesis

Most lacquer dermatitis is caused by direct contact with paint or lacquered items.

Tung oil

The resulting skin disease has only been reported in foreign literature.

2. Raw lacquer

It is quite common to cause skin reactions. It is seen in the collection, preparation, transportation, processing and use. The incidence of lacquer dermatitis in the paint tube workers of a yarn factory and the paint workers in a printing and dyeing factory. They are all in the range of 80% to 90%. It is generally believed that the paint liquid enters the body mainly through the hair follicle mouth. The onset of the disease is sooner or later, and the severity of the symptoms varies. Even in the same person, the incidence is not the same every time. Whether or not allergic reactions may or may not occur in repeated exposures in the future. From many clinical and on-site investigations, raw lacquer can cause disease through primary stimuli, but at the same time it is a complex sensitization. Originally, in general, it is like the former. At present, the main component of lacquer is that urushiol is the main cause of skin allergic reaction, especially some of the volatile substances. The longer the lacquer is stored, the more volatiles escape. The more it is, the less susceptible it is to sensitization than fresh paint.

3. The cause of synthetic resin paint depends on its variety.

4. Ordinary paint itself rarely causes skin diseases, and it is only caused by contact with certain pigments (such as chrome yellow, Lissol red, etc.) or solvents (such as turpentine, banana water, etc.) in the preparation to cause dermatitis.

Skin disease prevention caused by paint

1. Pay attention to the operation rules: smelt, modulate and use all kinds of paints or hazardous pigments. When using resin, try to avoid staining the skin and clothes.

2. Keep the working environment clean and tidy: the workshop should have good ventilation and exhaust equipment, especially the place where the paint liquid or the paint liquid is placed.

3. Strictly carry out personal protection: use headscarves, overalls, gloves, rubber boots, aprons, and apply appropriate skin protectants as appropriate. Wash hands after work, such as paint stains, can be washed with caustic potash, glycerin mixture ( Formulation: caustic potash 1.0, glycerol 10.0, ethanol 30.0, water 60.0).

4. Allergy identification: If you want to choose a worker who is ready to engage in raw lacquer operation, you can first use the 1:1000 lacquer ethanol solution for the patch test. Anyone who is negative or only slightly reactive can participate in the work; if the reaction is strong positive, it shows high sensitivity. It is not appropriate to participate in such work.

Skin disease complications caused by paint Complications

Ordinary paint can cause folliculitis, or some of the oily ingredients can also cause folliculitis.

Symptoms of skin diseases caused by paint Common symptoms Pimples wheal or bullae damage edema and loss of appetite

Pigment dermatitis is the most typical and representative. It usually occurs from 1 to 2 hours to 10 days after direct or indirect contact. Most of the initial development is only in the exposed area, such as face, neck, wrist joints, back of the hand and forearm. Many, a small number can occur in the penis, foreskin, scrotum and medial femoral, which can be extended to the trunk, limbs, etc., secondary sites may be related to scratching, all cases are acute, first itching, burning, followed by That is, skin lesions appear in the above-mentioned parts, which can be divided into two types according to their performance:

1. The dermatitis is light and heavy. The lighter ones have only large edematous erythema and scorpion-like rash, no blisters, and severe swells and swellings in the affected area, followed by rapid intensive red pimples from the needle to the miliary size, and rapidly change. For blisters or bullae, after breaking, a large smashed surface is formed, which occurs in the face and genital area. The redness and swelling are particularly prominent. In severe cases, the body can be spread, accompanied by fever, headache, loss of appetite, etc., the course is self-limiting, roughly 1~ It will heal in 2 weeks.

2. The urticaria is mostly generalized in the body, showing a wind-like mass, bright red color, slower regression, and positive skin scratching reaction.

Examination of skin diseases caused by paint

Laboratory inspection

1. The disease is an allergic disease, so hematology and serology check the peripheral blood eosinophilia. T lymphocytes (especially Ts) are reduced. Serum IgE levels were significantly increased.

2. Skin tests are often positive for allergic reactions to certain allergens (eg fungi, pollen, shavings). Intradermal test (delayed allergic reaction) with tuberculin, candida, etc., often negative or weakly positive.

3. Skin white scratch test The skin is scratched with a blunt instrument, and the skin has white scratches (normal people are red).

Diagnosis and identification of skin diseases caused by lacquer

According to the symptoms, the medical history can be diagnosed.

Identification with urticaria, the history of exposure to paint or paint is the main point of identification.
