Possible factors associated with bleeding from endoscopy-detected chronic subdural hematomas (CSDHs) have rarely been analyzed. We therefore evaluated intraoperative endoscopic findings to elucidate the clinical course and assess predictors of CSDH recurrence. ⋯ Evaluation of the changes in the endoscopic findings and their association with recurrence was useful for clarifying the mechanism of CSDH enlargement, the risk of recurrence, and the potential for endoscopic surgery.

By extracting clinical and computed tomography imaging data of patients with acute subdural hematoma (ASDH), factors that were significantly associated with poor prognosis were screened and a nomogram model was established and validated. ⋯ The nomogram model had high accuracy for predicting poor prognosis in patients with ASDH, and it was easy to promote. In the future, large sample and multicenter prospective studies are necessary to complement and identify the results.

To investigate changes of oblique corridor in patients with lumbar degenerative scoliosis and determine proper working angle with respect to the direction of vertebral axial rotation during the oblique lumbar interbody fusion procedure. ⋯ In the left apex group, the oblique corridor was decreased from psoas overlap, and coupled axial rotation to the left side might increase the risk of contralateral nerve root injury during orthogonally working. Thus, surgeons should pay attention to the state of coupled vertebral axial rotation of lumbar degenerative scoliosis for the oblique lumbar interbody fusion procedure.

We aimed to evaluate neuroprotective effects of tocilizumab on spinal cord ischemia-reperfusion (I/R) injury. Our study design was an experimental rabbit spinal cord I/R injury model, and the setting was at the Animal Research Laboratory, Necmettin Erbakan University, Meram School of Medicine, Konya, Turkey. ⋯ This study shows significant neuroprotective effects of tocilizumab on rabbit spinal cord I/R injury.

Dura of the anterior clinoid process (ACP) is presumably supplied by the ophthalmic and external carotid artery branches. There is a less recognized artery described by Yasargil that arises directly from the supraclinoid internal carotid artery (ICA) and supplies the ACP dura. We studied the origin and course of this direct branch in patients in whom the carotid cistern was dissected for lesions not involving the carotid cistern and ACP dura. The management implications of this arterial twig have been described. ⋯ The knowledge of this arterial twig to the clinoidal dura is important as this supply may be responsible for feeding the tumor arising from the dura arising from the anterior clinoid, making preoperative embolization impossible. In addition, the tumor may grow along with this vessel and infiltrate the adventitia of the ICA at the origin of this vessel.
