When Bruises Don't Add Up: Recognizing Sentinel Injuries in Infants | Grand Rounds Episode

Link for CME Credit Coming Soon!

Join Host Holly Wayment and Daniel Reyes Ruiz, M.D., in this grand rounds episode of Pediatrics Now on sentinel injuries and infant bruising, emphasizing the importance of early recognition, common clinician biases, and the PEN‑4‑FACES framework for identifying high‑risk bruise locations in non‑mobile infants.

It reviews case examples, common medical mimics (bleeding disorders, birthmarks, dermatologic conditions), recommended evaluation steps (imaging, skeletal survey, hematology workup), and when to consult child protection resources to ensure infant safety.

Spurs Team Orthopedic Surgeon Dr. Leah Brown on Concussions & Early TBI Identification

In the wake of star Spurs player Victor Wembanyama's concussion, San Antonio Spurs Head Team Orthopaedic Surgeon Dr. Leah Brown joins Pediatrics Now Host Holly Wayment to discuss concussion recognition and early traumatic brain injury (TBI) identification.

They talk about what happens medically in real time when a head injury is suspected and what pediatricians and frontline providers need to know to recognize and respond to concussion and early TBI.

It also reviews practical tools like SCAT-6, stepwise return-to-learn before return-to-play, activity progression thresholds, when to escalate care or image, the limits of protective headgear, and the need to change sports culture to prioritize brain health.

In this episode Holly Wayment interviews Dr. Lisa Carnell, Director of NASA's Biological and Physical Sciences Division, about the AVATAR bone marrow organ-chip experiment that flew on Artemis II! The team sent personalized microphysiological "organ chips" made from astronaut blood to study deep-space radiation effects and compare results directly to the crew.

They discuss how these small, high‑fidelity models can accelerate translational research for oncology and pediatric diseases, reduce animal testing, enable personalized treatments, and help protect astronaut health on long missions. The chips can model hematopoiesis, test therapies, and provide data on radiation and drug responses.

The amazing conversation also covers broader NASA science: growing plants in space, future lunar and Mars research, and the potential real‑world benefits of space-driven technology for healthcare on Earth. Pediatricians will learn about the incredible search and organ‑chip technology as a tool to personalize care and improve outcomes for children.
