The Dunedin parents of a young boy with cerebral palsy are not taking their eyes off him, as they watch for signs of improvement in his condition after taking him overseas for experimental stem cell treatment.
Lindsay and Shirley Turner, who returned with Caleb (2) from the United States yesterday, said the surgery had gone smoothly and they now faced an anxious wait for signs of success.
Doctors told them it could be up to six months before they saw any changes in Caleb.
Caleb suffered a massive brain bleed just days after birth and has severe cerebral palsy, which is incurable. He cannot walk, talk or even roll over, and can have up to 50 seizures a day.
The experimental treatment transplants donated umbilical cord stem cells into the patient. Umbilical cord stem cells are considered adult stem cells and are unrelated to embryonic stem cells.
The Turners said the day before Caleb underwent treatment they met a little boy, and his family, who had been through the procedure about six months before.
The boy, who walked into the restaurant, had previously been blind and unable to walk or talk.
"It just gave us a real boost seeing that wee boy," Mr Turner said.
Caleb was the first New Zealand child to travel overseas for treatment with donor umbilical stem cells.
"It was very stressful," Mrs Turner said.
"It is stressful enough if your child having an operation, never mind being in a different country and it [the treatment] is still a bit of an unknown."
The family met the doctors in the US, but the actual procedure was performed in Mexico, as it was not legal in the US. However, the medical team had been great and very professional, they said.
