Siamese twins in the United Arab Emirates

In the years 1985-1992, ten pairs of conjoined twins were born in the United Arab Emirates (UAE): one dicephalus, two teratopagi, and seven thoracoomphalopagi, one of which was still-born and three who were cared for in other hospitals. The first pair of thoraco-omphalopagus twins died of acute lymphoblastic leukaemia 6 months after successful separation. The management of the third set of twins gave rise to moral and ethical problems often encountered in such situations, while one of the teratopagi was a unique case of a parasite projecting from the mouth of the normal twin.
