Case Reports
Expanded endoscopic endonasal transtuberculum approach for resection of Germ cell tumor.
We present the case of a 16-year-old with short stature, fatigue, memory impairment, and pituitary gland failure. Imaging and cerebrospinal fluid (CSF) studies supported the diagnosis of a suprasellar nongerminomatous germ cell tumor with no clear radiologic disease in the spine; however, a single atypical cell was present in the CSF. After a period of external drainage via an Ommaya device, he was treated with chemotherapy, followed by craniospinal radiation. ⋯ We emphasize the strategies for perforator preservation including thalamoperforators and superior hypophyseal arteries to avoid ischemic injury and visual dysfunction, respectively. Postoperative scans demonstrated gross total resection without any ischemic injury. The patient was discharged without any neurologic deficit, visual dysfunction, or CSF leak.

The link between red cell distribution width (RDW) and prognosis of traumatic brain injury (TBI) is controversial. Whether RDW can increase the prognostic value of established predictors remains unknown. This study aimed to provide supportive evidence for the prognostic value of RDW. ⋯ Elevated RDW is an independent risk consideration for hospital and 6-month mortality rates. When RDW was added to the IMPACT core and extended models, it improved its predictive ability for 6-month mortality in patients with TBI.

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.
