Common pediatric issue: If a newborn’s vulva appears red after birth, it may be caused by vulvitis. It is recommended to use cefixime and other symptomatic anti-inflammatory medications for treatment, and to clean the area with potassium permanganate solution, followed by applying gentian violet ointment.

A four-month-old baby boy has an unusual smell in his penis, which may be a symptom of vulvitis. It is recommended to maintain good hygiene in the area, change diapers frequently, and use medication for treatment.
