What is the reason for the peculiar smell in the red?

Patient's question:

Female baby, 4 years old

Doctor's answer:

Hello, it should be vulvitis caused by bacterial infection. You can use potassium permanganate solution for sitz baths for treatment, or try taking azithromycin or cefixime orally in combination. Pay attention to maintaining local hygiene.
There are many triggers for pediatric endocrine diseases. If a child is diagnosed with pediatric endocrine disease, parents need to cooperate with the doctor for immediate treatment, including gastrointestinal decompression, and develop good hygiene habits. The child should have a balanced diet and avoid stimulating and cold foods.
