In this respect, we cannot exclude the possibility that at least a part of the S100B present in monoamniotic twins
is a consequence of compression of the fetuses in the sac.
Allison and Kevin Carlson will soon be taking home two great Christmas gifts from Lucile Packard Children's Hospital at Stanford - a set of rare monoamniotic twins
named Kate and Annie, delivered on November 7 at just 30 weeks old.

Incredibly, a consultant then told Karen that she could give birth naturally, despite the fact that monoamniotic twins
are nearly always delivered by Caesarian because of the danger of further cord entanglement.
Emma Canning, aged 36, had Christmas babies Hannah and Sophie, who were monoamniotic twins
- sharing the same birth sac and placenta.
