Babies’ skin is extremely delicate, so if they are wrapped in wet or dirty diapers for a long time, their skin will be irritated and a diaper rash will form. If the baby is immersed in urine for a long time or if the diaper is damp due to impermeability, a red rash or rough skin will appear on the buttocks, which is called “diaper rash” or “red buttocks” and can easily cause pustulosis, subcutaneous seborrheic dermatitis and prickly heat. How to diagnose the symptoms that cause itching on the buttocks of children? 1. Impetigo: Impetigo is a contagious bacterial skin infection that appears on the diaper area, face and hands, forming papules and yellowish trauma with scabs, accompanied by blisters and itching. Because the condition is contagious, all members of the family should wash their hands with antiseptic soap to avoid spreading the disease. If you see such wounds, call your pediatrician, who will prescribe antibiotic ointment or oral antibiotics. 2. Subcutaneous seborrheic dermatitis: Subcutaneous seborrheic dermatitis is a common skin condition that flares up during an infant’s first year. You will find raised, rough red patches covered by a thick white or yellow scaly layer on the infant’s groin, genitals, or lower abdomen. When similar spots appear on the scalp, they are commonly known as “cradle cap. Cortisone or hydrocortisone bought from the pharmacy can be applied to the affected area and kept clean and dry for the infant. If the condition does not improve quickly, see a pediatrician who will prescribe a more potent cortisone ointment. 3. Prickly heat: Heat and humidity can cause prickly heat because sweat builds up on the skin and cannot evaporate. It is less common in infants after three months of age. The condition looks like an acne attack, forming very small reddish pockets that can appear in the folds of the skin in the diaper area, especially where the plastic liner of the diaper or the diaper cover is in contact with the skin. The main causes of heat rash are moisture and humidity. So make sure your baby is not overdressed and that the skin is dry. If the heat rash is severe, you should contact your pediatrician.
