Dermatitis can occur on the face, limbs, neck, anus, eyelids and other parts. The pathogenesis is different, and the treatment mainly includes two aspects: etiology and symptoms. First of all, we must clarify the cause and remove the pathogenic factors. For example, patients with solar dermatitis should avoid the sun, patients with hormone-dependent dermatitis should stop using the original hormones, and patients with mango dermatitis should fast mangoes.

Secondly, patients with dermatitis should actively treat skin lesions and systemic symptoms, such as astringents for those with severe exudation and antipruritics for those who feel itchy.

Some patients have recurrent dermatitis, which may be caused by the persistence of inducing factors. If this happens, in addition to the etiological treatment and corresponding symptomatic treatment during the attack, we should also make clear the inducing factors as soon as possible, and then try to avoid these inducing factors in our daily life.

Common treatments for dermatitis include local medication, systemic medication and physical therapy.

Topical medication: Topical medication is the most commonly used treatment for dermatitis, which has the advantages of high local drug concentration, less systemic absorption and less adverse reactions. Such as topical glucocorticoid, calamine lotion, 3% boric acid solution, etc. can be used to treat dermatitis.

Systemic drug therapy: Systemic drug therapy refers to a treatment method of oral administration, intravenous injection and intramuscular injection. Commonly used drugs include antihistamines, oral glucocorticoids, antibacterial drugs and immunosuppressants.

Physical therapy: If narrow-band UVB is used to treat specific dermatitis, it can have a good effect.

According to the pathogenesis and severity of patients with different types of dermatitis, we choose single therapy or combined therapy among the three therapies and make an individualized treatment plan.

How to treat different types of dermatitis?

The etiology and pathogenesis of different types of dermatitis are different, and the treatment schemes are also different. This paper introduces several common types of dermatitis and their treatment schemes.

Insect bite dermatitis

Insect bite dermatitis refers to skin inflammation caused by insect bites such as mosquitoes, mites, ticks, bees, bedbugs, fleas, midges, etc. Its * * * feature is that the skin lesions can be marked with needle bite marks, and patients consciously itch. The severity of the disease is related to the species and quantity of insects and the sensitivity of patients. Insect contact history is an important clue to diagnose the disease, and bite marks or target-like lesions observed by dermoscopy are direct evidence for diagnosis.
