In recent years, the view that smoking is a potential risk factor for psoriasis has been continuously raised, and this view has been confirmed by many studies. Some people surveyed the smoking habits of a group of patients with psoriasis before the onset, and compared with the local residents who did not have the disease. The results showed that psoriasis was significantly related to smoking habits. Other reliable studies suggest that smoking is a risk factor for psoriasis, especially in women. Unlike drinking, the effect of drinking on psoriasis is after the onset, and the effect of smoking is onset. In other words, smoking may be one of the causes of psoriasis.
Palmoplantar plantar pustular disease Palmoplantar plantar pustular disease is a chronic recurrent skin disease, the cause of which is currently unknown. Some people think that this is a variant or subtype of psoriasis, but it is now generally considered to be an independent disease. A foreign study of 216 cases of palmoplantar impetigo and 626 cases of various other skin diseases as a control group showed that 80% of patients with palmoplantar impetigo were smokers at the time of the disease, while only 36% are smokers. The results also showed that smokers were 7.2 times more likely to develop palmoplantar impetigo compared with nonsmokers.
Palm eczema A foreign study of 153 palm eczema patients found 3 related factors, namely taking aspirin, taking contraceptives, and smoking. The effects of smoking on palm eczema are mainly seen in men. Smoking plays a role in the occurrence, treatment and recurrence of the disease, leading to the elongation of eczema in the palm.
Deck changes Smoker's finger skin and nails are stained yellow, known as the "Nicotine (Nicotine) Mark". Long-term smoking can lead to progressive crooked nails and soft nail atrophy, which are called "broken nails" or "claw nails". Long-term smokers abstain from smoking or sudden illness and stop smoking. A clear dividing line appears between the distally pigmented nails and the newly born nonpigmented nails. The distance between the telekinesis fold and the dividing line can be used to infer the date when smoking is stopped.
Melanoma and squamous cell carcinoma Although smoking does not cause the occurrence of melanoma and does not increase the chance of melanoma, the following points have been confirmed by research: (1) the primary cause of melanoma in smokers Lesions are more likely to metastasize; (2) smokers have a lower survival rate after diagnosis; (3) smokers are more likely to have visceral metastases; and (4) smokers are more likely to die from melanoma. Studies have also shown that there is a very significant link between smoking and squamous cell carcinoma. Smokers have a 50% greater risk of developing squamous cell carcinoma than nonsmokers, and the risk increases with the amount and duration of smoking. Smoking has a poor prognosis and increased risk of squamous cell carcinoma, which may be related to the adverse effects of smoking on the immune system.
Oral cancer, lip cancer, and anogenital cancer Oral cancer has a positive relationship with smoking, which has been confirmed by research. The main risk factors for lip cancer are sunlight and smoking, and they are the result of a combination of these two factors. Anal genital skin cancer is also associated with smoking. Surveys show that people who smoke more than 10 cigarettes a day are twice as likely to develop penile cancer as non-smokers, and those who have been smoking for more than 45 years are more at risk. Anal canal cancer, genital cancer, cervical cancer, etc. are also closely related to smoking.
