Here's an alternative source in Swedish from the magazine Läkartidningen, a magazine by the Swedish Medical Association.

Strangely the article in Läkartidningen doesn't say when this incident occurred (just the middle of December).
I'm not saying it didn't happen, just that everything written about it reads like promotional material rather than journalism.

But I'm a bit surprised that this is not considered bigger news.
