The twins who share a body.

This documentary follows two pairs of conjoined twins and looks at their health concerns. Both pairs are dicephalic parapagus twins, a condition thought to affect one in a million people; they share one body but have two heads. Sohna and Mohna have grown up in an orphanage in Amritsar, India. They are about to turn 9 and they live a normal life, going to school and playing. When they were 6 tests revealed that they had two separate hearts, helping them to lead active, healthy lives. Radiologist Dr Rakesh Chouhan investigates how they have adapted to living in a single body. The twins Jesus and Emanoel were recently born in Brazil. Medical staff in the hospital and their family in the rainforest consider their futures. The boys have separate nerves, but an MRI scan reveals that they only have one heart and cannot be separated. Mr Edward Kiely, Paediatric Surgeon from Great Ormond Street Hospital, considers the possibility of separating the boys. The ethical issues that would be involved in their separation are discussed by Julian Savulescu, Uehiro Chair in Practical Ethics, Oxford. Despite the hospital’s best efforts, the twins die at 6 months old. A look at the reality show of twenty-two year old American conjoined twins Abby and Brittany Hensel shows how they continue to defy expectations.
