Halla

Pediatric gastroenterologist Erick Hernandez, who helped treat Halla, said patients with the condition suffer massive diarrhea and need constant feeding.

In fact, it has been a difficult road for Halla, as well as her older sister, Janna. Last August, Janna, 2, underwent a similar multiple organ transplant to address the congenital disease. Since then, doctors say she has recovered well and has returned home with her father to the Haifa area in northern Israel.
