This study aimed to establish a predictive nomogram model for recollapse of fractured vertebra after posterior pedicle screw fixation in thoracolumbar fractures (TLFs). ⋯ A clinical nomogram incorporating 4 variables was constructed to predict fractured vertebra recollapse after posterior pedicle screw fixation for TLFs. The nomogram demonstrated good calibration and discriminative abilities, which may help clinicians to make better treatment decisions.

Short-lasting cough-associated headache (CAH) in patients with Chiari I malformation (CMI) is believed to be due to transient worsening of cerebrospinal flow (CSF) obstruction at the foramen magnum. We assessed changes in CSF flow in response to coughing in CMI patients with CAH and compared with those without CAH and healthy participants (HPs) using real-time magnetic resonance imaging. ⋯ A decrease in CSF flow after coughing in CMI patients with CAH supports the notion that CAH is caused by transient worsening of CSF flow obstruction at the foramen magnum.

Malnutrition frequently is associated with increased complications and worse outcomes after surgery. The purpose of this study was to determine whether malnutrition status determined using the Geriatric Nutritional Risk Index (GNRI) can serve as an independent risk factor for complications in patients undergoing anterior cervical discectomy and fusion (ACDF). ⋯ In elderly patients after ACDF, malnutrition determined using GNRI is an independent risk factor for 30-day complications, readmissions, prolonged hospital length of stay, and nonhome discharge.

Case Reports
Multiple intracranial schwannomas of the vestibular and trigeminal nerves: Technical note.
A schwannoma is a nerve sheath tumor that is formed by Schwann cells. Vestibular schwannomas are thought to account for the majority of intracranial schwannomas. Nonvestibular schwannomas account for about 10%, about half of which are trigeminal schwannomas. Multiple intracranial schwannomas originating from different cranial nerves are extremely rare. ⋯ The presence of multiple intracranial schwannomas is extremely rare in neurosurgical practice and can change the intraoperative strategy and the course of the surgery.

Comparative Study
Comparison of the Transcranial Approach and Transsphenoidal Approach Based on the Anatomical Location of Origin in Pediatric Craniopharyngiomas.
Various clinical classifications of craniopharyngiomas (CRPs) have been proposed to suggest optimal surgical planning. We aimed to evaluate the clinical outcomes of pediatric CRPs and the clinical significance of anatomical classification in relation to the diaphragm sellae. ⋯ Over time, with the adoption of EEA at our institute, the impact of anatomical classification on the surgical approach has decreased. Nevertheless, an individualized surgical approach should be employed to improve long-term outcomes and minimize complications for pediatric CRPs.
