Comparative Study
Discrepancy between internal and external intracranial pressure transducers: quantification of an old source of error in EVDs?
Intracranial pressure monitoring remains the foundation for prevention of secondary injury after traumatic brain injury and is most commonly performed using an external ventricular drain or intraparenchymal pressure monitor. The Integra Flex ventricular catheter combines an external ventricular catheter with a pressure transducer embedded in the tip of the catheter to allow continuous pressure readings while simultaneously draining cerebrospinal fluid. Discrepancies between measurements from the continuously reported internal pressure transducer and intermittently assessed and externally transduced ventricular drain prompted an analysis and characterization of pressures transduced from the same ventricular source. ⋯ This study suggests that the internal pressure transducer may be a more reliable estimate of intracranial pressure relative to bedside external transducers due to the inherent behavioral requirement of leveling.

Although postoperative urinary retention (POUR) is common after spine surgery, the association of this adverse event with other morbidities and patient-reported outcomes is not fully understood. We sought to examine the sequelae of POUR after lumbar spine surgery. ⋯ POUR is common after lumbar spine surgery, and the demographic, diagnostic, and surgical factors that are associated with POUR are identified. POUR is associated with several adverse events, and patients who have POUR were less likely to be satisfied with surgery up to 2 years after surgery.

We sought to report the safety of implementation of a novel standard of care protocol using spinal cord perfusion pressure (SCPP) maintenance for managing traumatic spinal cord injury (SCI) in lieu of mean arterial pressure goals at a U.S. Level I trauma center. ⋯ In our initial experience of 15 patients with acute SCI, standardized SCPP goal-directed care based on LSAD monitoring for 5 days was feasible. There were no SCPP-related complications. This is the first report of SCPP implementation as clinical standard of care in acute SCI.

Comparative Study
Prognosis comparison of different branches of trigeminal neuralgia.
We explored the remission rate of different branches of the trigeminal nerve after microvascular decompression. ⋯ Postoperative remission rate of non-V2-related branches (V1, V3) are higher than V2-related branches (V2, V1-2, V1-3, V2-3).

Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) in an immunocompromised patient with organ transplantation demonstrated unusual brain magnetic resonance imaging (MRI) findings. Recognition of EBV-positive DLBCL by radiologists on MRI may prevent unnecessary neurosurgical resection, and it could be important to obtain viable cells for accurate diagnosis on stereotactic biopsy because of extensive necrosis. ⋯ We report an immunocompromised patient with EBV-positive DLBCL, which showed atypical MRI findings, including extensive necrosis. Multiple biopsies were required for final diagnosis.
