I think that it does not relate to childhood as a period in time but the age of women, i.e. young girls. I think it could be expressed otherwise as: si pensa subito a problematiche relative alle bambine, that is why I would propose:

issues relating to children or young girls --

...or something along these lines.
In this case the literal translation doesn't work well for me.

in pediatric gynecology. We report a case of vaginal foreign body presenting as vaginal. bleeding and a foul‑smelling discharge in a young girl.

Any object placed inside the vagina is called a vaginal foreign body.

Small amounts of tissue paper are the most common vaginal foreign body found in young girls. In some cases, young girls curious about their bodies may place small objects inside the vagina. This can include things like crayons, beads, coins, batteries, or twigs. Rarely, these may be a sign of sexual abuse.

They may be forgotten, or once placed in the vagina, unable to be removed by the child. Other common objects include marker caps or crayons. The objects found in children generally are small and do not cause pain from distention of the hymen or vaginal opening at the time of placement. Children will generally not place objects larger than the vaginal entrance due to discomfort.

Adolescent women may use tampons once they begin menstruating. Occasionally, these tampons are forgotten and may not be removed for days. The breakage of a condom may also result in bits of latex or non-latex material being left in the vaginal vault.

If an object is left inside the vagina or becomes stuck, it can cause symptoms over time. If not removed, it can also lead to infection and damage nearby tissues.
