Understanding Homocystinuria (HCU): How one Mother Uncovered her Son's Diagnosis
Inside the Children's HospitalShow Notes
Melanie, mom to 12-year-old Masen, shares the unexpected path to her son's diagnosis with Homocystinuria (HCU) after a routine eye exam revealed something "off."

In today's episode, we sat down with Kristen Cowan, a teacher, and mom of Rylen and Corbin. In 2017, Rylen was only 13 months old when he woke up with a fever that turned out to be bacterial meningitis. Rylen was in the hospital for about 9 days before he unfortunately passed away from the illness. Kristen shares her journey of being in the hospital with Rylen, and how she was able to provide a new hope for other families through organ donation. Throughout the episode, Kristen unpacks how she is able to cope with the loss of Rylen by creating a legacy through the Smilin' Rylen Foundation. The foundation was made to honor Rylen by raising awareness about organ donation and assisting families in crisis by offering to pay for hospital parking passes.
For this week's episode, Katie is talking with fellow child-life specialist, Annie "Sunshine" Gunning. For 25 years, Annie has helped adapt typical playtime into something that everyone with different needs, such as children who are nonverbal or wheelchair bound, can enjoy. Annie gives us insight into how playing through medical experiences like going to a therapy appointment is important for children to understand the world around them. Similarly, Annie leads us into the hospital setting, detailing how play inside the hospital can create positive environments for children, especially for children who are staying for a longer period of time.
