Dear Morquio Community,

We had an urgent incidence on obstructive trachea in a 16-year-old Morquio patient. His respiratory situation went down and was at a high risk. He needed an artificial ventilation and had an urgent operation at Nemours/Alfred I. duPont Hospital for Children in Wilmington, Delaware. The operation was successfully done by cardiologist, Dr. Pizarro and his team. The child's life was saved. We are very pleased to hear this great news since many Morquio patients have died in the past due to airway complications.


Dr. Pizarro will make a presentation of this new surgical procedure at the up coming Morquio Conference (July 17-19, 2015). Dr. Tomatsu and his research team are now researching the mechanism of trachea obstruction with Dr. Pizarro.


Please let us know if you have any concern about trachea obstruction.

Also the hospital now accepts patients up to 35 years old.



Dr. Shunji Tomatsu
