The etiology of infantile eczema is complex, and its onset is related to a variety of internal and external factors, and sometimes it is difficult to identify a specific cause. Often, the child’s digestive tract ingests food allergens such as fish, shrimp, beef and lamb, eggs and other sensitizing factors, causing a type I allergic reaction to occur in the body. The high incidence of eczema in infants is mainly due to the thin skin stratum corneum, the rich capillary network, and the high water and chloride content of the endothelium of the affected children, which makes them susceptible to allergic reactions. In addition, mechanical friction such as saliva and spilled milk often irritates and is a trigger for this disease. Improper care, such as excessive use of strong alkaline soaps, excessive nutrition, and abnormal intestinal fermentation, can also cause the disease. Some infants, especially during the neonatal period, are prone to seborrheic eczema due to increased sebum in newborns as a result of maternal estrogen being passed to the fetus through the placenta. Some infants have genetic allergic qualities (atopic qualities) and a family history of atopic dermatitis, ichthyosis, asthma or allergic rhinitis, etc. The affected infants have food allergies, increased IgE values in the blood and increased eosinophils. As they grow older, the skin damage is gradually restricted to the flexors of the extremities (elbow fossa, N fossa), often with intense scratching and repeated itching until childhood or even into adulthood. Certain external factors such as sunlight, ultraviolet light, cold, heat and humidity and other physical factors, contact with silk or artificial fibers, topical medications and bacterial skin infections can cause eczema or aggravate its condition. The acute phase is the same as contact dermatitis. In the chronic phase, the epidermis is hyperkeratotic and hyperkeratotic, the spiny layer is thickened, the epidermal protrusions are widened and extended, the dermal papillae are thickened, and the superficial blood vessels are surrounded by lymphocytes, histiocytes and a few eosinophilic infiltrates. The children with eczema should focus on the following in their daily care: (1) Use soap as little as possible and do not use alkaline soap. In addition to using the applicable baby face oil, do not use any cosmetics; (2) do not wear chemical fiber, woolen clothing, soft light-colored cotton is appropriate, clothing should be loose, do not wear too much cover; (3) in order to avoid scratching the skin infection, can be loosely wrapped in soft cloth hands, but be diligent observation, to prevent the threads winding fingers; (4) scalp and eyebrows and other parts of the scab, can be coated with disinfectant cooking oil, and then the next day (5) When eczema strikes, do not do vaccination to avoid adverse reactions. Pediatric eczema can make children itchy, sleepless and restless at night. Medication has some effect. If necessary, you can use anti-inflammatory, anti-itch and desensitizing drugs under the guidance of the hospital, but do not use any hormonal creams such as “Skin Easy” by yourself. Because too many of these drugs can be absorbed into the skin and cause side effects, long-term use can also cause local skin pigmentation or mild atrophy. The child will often relapse after stopping the medication, so if the scratching affects sleep, ask your doctor to prescribe some sedative medication. If the eczema becomes infected with pus or if the child develops a fever as a result, he or she should go to the hospital promptly. As the weather warms up, the number of children with eczema starts to increase. According to statistics, infant eczema accounts for 60% of all recent outpatient visits. Infant eczema is often referred to as ringworm, and many mothers are afraid to breastfeed their children for fear of aggravating their eczema. However, if the allergy is not caused by drinking breast milk or drinking milk, there is no need to quit breast milk. The skin of infants is delicate and sensitive to external allergens or cold air stimuli, and once there are allergens in the air or temperature changes, it can cause eczema. Also, some allergic babies can develop eczema after eating foods that can cause allergies such as milk and egg yolk. Also, if the mother unintentionally eats fish, shrimp, crab, citrus, tomatoes, or comes in contact with allergens such as wool, feathers, dust, etc. while breastfeeding, it can also cause eczema. In addition, certain soaps or detergents can also trigger eczema in infants. When a child develops eczema, the doctor will prescribe a number of ointments with different functions depending on the severity of the eczema symptoms. If the symptoms are relatively mild, you can use topical baby eczema cream, zinc oxide ointment, etc. If more small red dots have appeared, herbal snake fat ointment can be used. Parents should be aware that these ointments may contain hormonal ingredients, so they are only suitable for short-term use. If the eczema comes back and you need to use ointment, the new mother must not act on her experience and must see the doctor again and give her baby the medicine with a new prescription.
