Sweden's medical negligence board, HSAN, is to investigate the case of a boy who had a six centimetre lollipop stick up his nose for eleven months. None of the seven doctors who examined him in that time managed to find it, reported Expressen.

The stick was not found until the spring, when it was discovered embedded in inflamed tissue.

"A series of unfortunate circumstances meant that it wasn't discovered earlier," said Finn Jörgensen, head of Halmstad hospital's ear, nose and throat clinic.

"Clearly there has been a failing in the follow-up, but the inquiry will tell us more," he added.
