Article Synopsis
- Regeneration after spinal cord injury (SCI) is hindered by glial scars and inhibitory signals, but tissue engineering with micro-tissue engineered neural networks (micro-TENNs) shows potential for promoting nerve repair.
- In a study involving 43 female rats, micro-TENNs containing sensory neurons were implanted across the injury site after a minimally invasive SCI model was created, demonstrating the survival of graft neurons and axonal growth.
- The positive findings, including minimal trauma and scar formation, suggest that micro-TENNs could serve as a living bridge to enhance recovery following SCI, laying the groundwork for further research.
Background: Osteoradionecrosis (ORN) refers to the degenerative changes seen in bone after local radiation, particularly in head and neck cancer. ORN can present as neck or facial pain and may be confused with tumor recurrence. Magnetic resonance imaging (MRI) and positron emission tomography (PET) scans are often inconclusive, requiring percutaneous biopsy to differentiate ORN from infection and recurrent disease.

Methods: In total, 729 patients with CST were retrospectively analyzed, including rates of VAI, age at injury, cause of injury, cardiovascular history, smoking history, substance abuse history, embolization therapy, and antiplatelet or anticoagulant therapy prior or after injury.
