Formaldehyde poisoning's dermatitis symptoms include skin redness, rash, and itching, with severe cases presenting with bumps, acne, and dandruff. If untreated, the condition may worsen, leading to skin ulcers, characteristic of contact formaldehyde poisoning. Firstly, it is crucial to leave the formaldehyde-contaminated environment and go to a well-ventilated area or, if possible, to receive oxygen treatment. Oral antihistamines such as cetirizine or loratadine can be taken to ease the symptoms. In cases with more pronounced symptoms, intravenous antihistamines like dexamethasone, calcium gluconate, and high doses of vitamin C should be administered to alleviate symptoms. If there are acne or bacterial skin infections, oral anti-inflammatory medications like cefprozil capsules should be taken, and intravenous anti-infection medications may be necessary to control symptoms. Workers regularly exposed to formaldehyde should wear protective clothing to prevent contact dermatitis. (Please use medications under the guidance of a doctor.)

The difference between neurodermatitis and allergic dermatitis

Neurodermatitis, also known as chronic simple lichen, is a common chronic inflammatory skin disease characterized by paroxysmal severe itching and lichenoid skin changes. Its main causes may be related to various internal and external factors such as neuropsychiatric factors, gastrointestinal dysfunction, endocrine disorders, diet, and local skin irritation. It commonly occurs on the neck, elbows, lumbosacral area, inner thighs, perineum, and around the anus. The skin lesions are characterized by pinpoint or rice grain-sized polygonal flat papules that are pale red, tan, or normal skin color, with a hard and glossy texture. They may be covered with a small amount of scale and, over time, can merge into large plaques, leading to thickened, rough skin with lichenoid changes. Allergic dermatitis is an hypersensitivity reaction skin disease caused by contact with various allergens, characterized by diverse skin lesions such as erythema, papules, vesicles, swelling, and itching, which can occur all over the body. However, localized allergic dermatitis, if treated improperly or not treated in a timely manner, or due to repeated scratching, can potentially develop into neurodermatitis.

How to treat insect bite dermatitis?

Insect bite dermatitis, medically also known as papular urticaria, generally presents with mild symptoms. It appears as a red welt with possible small blisters in the center. This type of dermatitis typically improves with the application of calamine lotion. For severe redness and pain, antiallergic medication such as loratadine can be taken, and topical corticosteroids may be applied. More severe symptoms may include blisters, erosion, and rupture. In such cases, it is advisable to seek treatment at a dermatology department of a formal hospital where the affected area can be cleaned with iodine and treated with infrared therapy, supplemented appropriately with oral traditional Chinese medicine that clears heat and detoxifies, such as Potentilla chinensis anti-inflammatory oral solution.

How to treat alcoholic dermatitis?

Alcohol allergy has caused dermatitis, presenting an allergic reaction with symptoms such as rash, generalized itching, and dizziness. Oral administration of loratadine or levocetirizine tablets can be used for anti-allergy treatment. If the rash is severe and covers a large area, an external application of calamine lotion can be used, which has anti-allergic and astringent effects. If oral medication is less effective, intravenous administration of calcium gluconate and high doses of vitamin C can be considered, along with the addition of dexamethasone for anti-allergy treatment, which generally provides relief. At the same time, it is necessary to avoid alcohol and try to eliminate it from the body, which can be facilitated by inducing vomiting or using laxatives to prevent reabsorption that could worsen the dermatitis or cause chronic issues. (Medication should be used under the guidance of a physician.)

How to treat diaper rash dermatitis?

Diaper dermatitis is primarily a type of contact dermatitis that occurs because the diapers soaked with urine and feces are not changed in time. Decomposition materials in urine and feces irritate the skin, causing inflammation. The main treatment involves keeping the buttocks dry and changing diapers frequently. It is necessary to wash the buttocks, genital area, and surrounding skin with clean water daily, and to rinse the anus and surrounding skin with water after bowel movements. Diapers should be thoroughly rinsed with clean water and not wrapped with plastic on the outside. If using disposable diapers, choose ones that are soft, not rough, and breathable. If there is a bacterial or fungal infection, topical antibiotics or antifungal medications should be used. For mild cases with only redness, consider keeping the buttocks dry. In cases where there is significant erosion, some medications may be used for intervention. If there is skin redness, topical calamine lotion can be applied. If the diaper dermatitis is severe and the baby is fussy and uncomfortable, it is advised to visit a hospital for a doctor to provide treatment based on the specific condition of the baby.
