Introduction

Vulvalandvaginalproblems in young girls often result inpruritusvulvae(itch affecting the femalegenitalarea). Causes and treatments differ slightly between prepubertal females and mature women.

The prepubertalvulvais thin, delicate, and has a neutralpH, meaning it is easily irritated. Older women are somewhat protected byoestrogen-inducedlabialfat pads, thickening of the skin, and pubichair.

  • Urinating or bowel movement may contaminate the vulva with urine and faeces.
  • Soaps, bubble baths, laundry detergents, shampoo, and chlorinated pool water are potential chemical irritants.
  • Mechanical irritation may occur from scratching, wiping with toilet paper, or tight-fitting underwear.

Prepubertal pruritus vulvae may also be asymptomof othervulvaror vaginal problems. These include:

Often several factors are present, and it can be difficult to determine the exact cause.

诊断是怎么来的in a prepubertal girl with vulval or vaginal problems?

Mostly the diagnosis is made by careful history and clinical examination by an experienced doctor. The doctor will need to examine the affected area and take swabs for microbiological examination. Other areas of the skin will be examined to determine the likelihood of a morewidespreadskin disorder being the cause.

Sometimes, askinbiopsyis necessary to determine the exact nature of the skin condition.

Patchtestsare sometimes performed to see whether anycontactallergyis present such as to afragrance,preservative, medicament or anotherallergen.

What treatment is available for prepubertal vulval and vaginal problems?

Prepubertal vulval and vaginal problems can be treated and prevented by instituting good hygiene measures and by avoiding things that may cause irritation or infection. Some basic practices include:

  • Using a front to back motion when wiping the vulva after urination or bowel movement.
  • Separate legs when passing urine to reduce vaginal retention of urine.
  • Change underpants frequently if soiled.
  • Wear loose-fitting comfortable underwear and outer clothing.
  • Avoid tight-fitting nylon clothing such as leotards and pants that restrict airflow and promote sweating.
  • Avoid using bubble baths or allowing the child to sit in soapy bath water for long periods. However, a soap-free bath can be very soothing and will improve hygiene. The child should gently use her fingers to separate the folds of the vulva but should try not to rub or scratch.
  • Avoid harsh soaps; try asoap-free cleanserinstead of conventional soap.
  • Pat dry the vulva with a clean towel after bathing rather than rubbing vigorously.

Blandemollientssuch as sorbolene and glycerinecreamor petrolatum can be used.Hydrocortisonecream is generally safe, but if it seems to irritate, discontinue its use and seek advice. Dermatological or infectious causes may be treated with medicines prescribed by a doctor.
