3 diagnostic principles

According to a clear history of occupational exposure, the unique clinical manifestations and the incidence of parts; reference service age, age of onset, operating environment survey And epidemiological survey data; combined with the dynamic observation of the disease, a comprehensive analysis, excluding acne vulgaris and non-occupational exogenous Acne can be diagnosed.

4 diagnostic criteria

4.1 oil acne Most of the hair follicle lesions occurred in the contact area, showing pore expansion, hair follicle keratosis, broken hair and blackheads. Often Inflammatory papules, folliculitis, nodules and cysts. Larger blackheads squeeze blackheads with lipid embolization, often with recessive scars. Skin lesions generally no symptoms or mild itching or tingling. Occurred in the eyelids, auricles, limbs stretch side, especially with oil impregnation Of the clothes friction parts, but not limited to the face and neck, chest, back, shoulder and other common parts of acne. 4.2 Chlorine acne Contact with the site of the hair follicle lesions, the performance of the main blackheads. Early onset often outside the eye and the zygomatic appear dense Set the tip of the big black spots, the course of time in the auricle around the abdomen, buttocks and scrotum, etc. appear large blackheads, accompanied by hair Capsule keratosis, between the millet papules-like lesions, inflammatory papules rare.

6 Correct use of the description of this standard

See Appendix A (informative), Appendix B (normative).

Appendix A

(Informative) Correctly use the instructions in this standard A.1 This standard applies only to the diagnosis and treatment of oil acne and chlorinated acne caused by occupational causes. Other illnesses and occupational contacts Clear cause and effect of acne, according to the provisions of GBZ 18 principles, with reference to this standard for diagnosis and treatment. A.2 Occupational acne is a chronic skin damage, the onset of latency depends on the nature of the contact with the disease, the dose, the role of time And individual quality and other comprehensive factors. So in the standard only to have a clear longer period of professional contact history, but not with a Body period. Diagnosis can be based on a comprehensive role, a comprehensive consideration of the decision. A.3 Occupational acne is a multifactorial disease, acne caused by a variety of pathogens, the clinical manifestations are not the same. For ease of control, According to the main pathogen and clinical manifestations are similar, summarized as oil acne and chlorine acne two categories. Both are just classified, not fixed Of the rash, the diagnosis should be unified diagnosis of occupational acne. For ease of handling, if necessary, indicate pathogens in brackets, for example Occupational acne (caused by XX). A.4 oil acne before the onset of a clear longer contact with tar (or crude oil), asphalt and high boiling fraction of mineral oil (such as wood Oil, oil and various lubricants). Chlorine acne before the onset of a clear longer contact with polychlorobenzene, polychlorinated naphthalene, polychlorophenol, certain brominated aromatic hydrocarbons and polyvinyl chloride The history of pyrolysis. Oil acne and acne vulgaris occur in the site of frequent contact with the disease; any age can be disease; the same working conditions of the same type of work May have more similar patients; from the contact with the pathogen after a certain period of time, the condition can be reduced or cured, but the cyst is not easy to subside; Repeated contact with the disease after a certain period of time, the condition can be aggravated or relapse.

A.6 Chlorine Acne is an acne that is caused by certain halogen compounds, which are mainly aromatic compounds of chlorine and bromine, pure chlorine and Bromine does not cause acne. Acne compounds are mainly polychlorinated naphthalene, polybrominated naphthalene, polychlorinated biphenyls, polybrominated biphenyls, polychlorobenzene, polychlorophenol Wait. Some chlorinated aromatic hydrocarbons in addition to skin contact, the inhalation or intake can lead to chlorine acne, such as polychlorinated biphenyl poisoning when the skin appears acne Sore rash, in this case should first deal with systemic poisoning. A.7 Occupational contraindications require sebum spillage or severe acne patients should not engage in contact with acne work, is taking into account acne And sebum secretion have a certain relationship, according to the physical arrangement of work, may reduce the incidence, but not absolute, so the already The industry can not use this as the basis for changing jobs.
