Objective: After previous success in regenerating canine peripheral nerves over 80 mm gaps using a bioabsorbable nerve guide tube, we have extended this method to the treatment of patients experiencing various types of nerve injury. This report describes the treatment of two cases of motor nerve disorder.
Methods: The bioabsorbable nerve tube was a cylindrically woven polyglycolic acid (PGA) tube filled with collagen. A peripheral motor nerve defect (the frontalis branch of the facial nerve) was reconstructed using this PGA-collagen tube in two patients who experienced posttraumatic unilateral eyebrow ptosis for 3 months.
Results: Five months after surgery, both patients regained their ability to voluntarily lift their eyebrows symmetrically. Electrophysiological examination at 5 months revealed recovery of compound muscle action potential and disappearance of distal latency on the affected side.
Conclusion: This is the first clinical report of motor nerve recovery achieved using the PGA-collagen nerve guide tube. The results suggest that use of a PGA-collagen tube is a promising option for the repair of motor nerve defects.

Cemdomespib Therapy Slows the Progression of Neuromuscular Weakness and Demyelination in the R75W-Connexin 32 Animal Model of Charcot-Marie-Tooth 1X Disease.

Mutations in connexin 32 (Cx32) are a common cause of Charcot-Marie-Tooth 1X (CMT1X) disease, an inherited peripheral neuropathy characterized by progressive neuromuscular weakness and demyelination. There are no approved pharmacologic therapies for CMT1X, and identifying new treatments that slow the onset and severity of neuromuscular decline may aid disease management. Cemdomespib is an orally bioavailable small molecule that improved demyelination and neuromuscular junction (NMJ) morphology in mice lacking Cx32 expression.

Introduction: Soft-tissue sarcomas arising in the thigh may require total or subtotal compartmentectomy, with subsequent need for functional reconstruction with free functional muscle transfer (FFMT). We present our series, describing a new approach with chimeric propeller antero-lateral thigh-vastus lateralis (ALT-VL) free flap, which allows for independent muscle inset and soft tissue defect resurfacing.
Patient And Methods: A retrospective review of a prospectively maintained database was performed, analyzing all patients referred to Fondazione Policlinico Universitario Campus Bio-Medico, Rome, Italy, between 2018 and 2023 for soft-tissue sarcomas of the thigh requiring wide excision and reconstruction with functional ALT-VL.

Stem cell transplantation is a promising strategy to establish neural relays in situ for spinal cord injury (SCI) repair. Recent research has reported short-term survival of exogenous cells, irrespective of immunosuppressive drugs (ISD), results in similar function recovery, though the mechanisms remain unclear. This study aims to validate this short-term repair effect and the potential mechanisms in large animals.

To date, there are no uniform guidelines for the treatment of obstetric plexus lesions in German-speaking countries. An end-to-end direct suture after resection of trunk neuroma is recommended for surgical treatment if tension-free coaptation is possible, whereas the use of autologous nerve grafts bridging the gap between the adaptation margins is advised by consensus if tension-free coaptation is impossible. The aim of the study was to investigate which reconstruction strategy may provide a better recovery of motor function for patients after obstetric brachial plexus lesion.

Premature infants, born before 37 weeks of gestation can have alterations in neurodevelopment and cognition, even when no anatomical lesions are evident. Resting-state functional neuroimaging of naturally sleeping babies has shown altered connectivity patterns, but there is limited evidence on the developmental trajectories of functional organization in preterm neonates. By using a large dataset from the developing Human Connectome Project, we explored the differences in graph theory properties between at-term (n = 332) and preterm (n = 115) neonates at term-equivalent age, considering the age subgroups proposed by the World Health Organization for premature birth.
