Postoperative early neuropraxia after lumbar disc herniation surgery is common. The emergence of new paresthesia findings with increased sensory and motor deficits in the postoperative period suggests iatrogenic neuropraxia. This study aimed to discuss the causes and prognosis of iatrogenic neuropraxia detected in the early postoperative period in patients who have been operated on for lumbar disc herniation. ⋯ Iatrogenic neuropraxia is a finding whose cause cannot be determined by quantitative criteria. It is common in patients who underwent aggressive discectomy. Methylprednisolone treatment is effective in recovering the paresthesia finding faster and may show that the radicular injury is in the neuropraxia stage in the early period.

Meningiomas involving major dural sinuses can be difficult to resect without proper handling of the sinus. In young patients, a gross total resection should be attempted when feasible. A 24-year-old man presented with headaches, progressive left-sided weakness, and partial motor seizures. ⋯ Videos 1-3 details the separation of the tumor from the convexity veins and the cortex, removal of the tumor from the SSS, and reconstruction of the SSS. Gross total resection of meningiomas involving the SSS is achievable without sacrificing the sinus when planned correctly and methodically. The patient consented for the procedure and to the publication of these images.

Previous research shows that scar tissue formed in the injured area after spinal cord injury blocks nerve regeneration and functional recovery. However, those researchers tried to prevent the formation of scar after spinal cord injury to promote nerve regeneration, but it ran counter to their desire, indicating that the formation of scar might play a role in functional recovery after spinal cord injury. ⋯ Excision of scar tissue in the second week promoted nerve regeneration after spinal cord injury. Tubb3 and Tubb6 genes might be the potential targets for spinal cord injury therapy in our study.

Traumatic brain injury is still an important health problem worldwide. Traumatic brain injury not only causes direct mechanical damage to the brain but also induces biochemical changes that lead to secondary nerve cell loss. In this study, we investigated the neuroprotective effect of milrinone after traumatic brain injury (TBI) in a rat model. ⋯ This study shows for the first time that the anti-inflammatory, antioxidant and antiapoptotic properties of milrinone may be neuroprotective after TBI.
