Skull base chordomas are clinically malignant because of the difficulty of total removal and the high recurrence rate. Because the disease-free survival after surgery is currently unpredictable, there is a need for new parameters, obtained from histologic analyses of the resection specimen, that allows a risk stratification of patients with chordoma. ⋯ The present study demonstrates the utility of the ultrastructural features in the prognostic outcome of patients with chordoma. According to the ultrastructures of chordomas, they can be divided into CDT and MRT. CDT chordoma cells have a more aggressive proliferative ability. Patients with CDT have a poor prognostic factor in clival chordoma, which has a higher risk of recurrence and a shorter survival.

To conduct a comparative analysis of 2 groups of patients with skull base chordomas extending onto the craniovertebral junction, who underwent surgical treatment using extracranial approaches with and without craniocervical fusion. ⋯ Use of the proposed surgical technique in clinical practice may help increase the radicality of tumor excisions, decrease the number of postoperative complications, accelerate the rehabilitation process, and increase the quality of life in patients with skull base tumors extending to the craniovertebral junction.

To investigate the impact of hospital teaching status on the timing of intervention and inpatient morbidity and mortality after surgery for acute spinal cord injury (SCI). ⋯ In this nationwide study, patients with vertebral column fractures with SCI who were admitted to teaching hospitals were more likely to receive early intervention compared to patients admitted to nonteaching hospitals. Future studies into the long-term implications of admission to teaching hospitals versus nonteaching hospitals for patients with SCI are encouraged.

We aimed to analyze infection rates in patients with spontaneous intracranial hemorrhage who underwent surgical external ventricular drain (EVD) placement. ⋯ Our findings suggest that EVD infection is a very common complication, occurring in 36.2% of cases. We adopted ventriculitis as the standard diagnosis, as advocated by the U.S. Centers for Disease Control and Prevention. Considering the high lethality associated with intracranial hemorrhage, use of a more aggressive treatment protocol for this patient population might improve morbidity and mortality rates.

The aim of the study was to investigate the diagnostic potential of interleukin 6 (IL-6) and other soluble biomarkers in serum and cerebrospinal fluid (CSF) for early diagnosis of cerebral vasospasm (cVSSAH) and external ventricular drain-associated ventriculitis (VCSAH) and to separate these conditions from aneurysmal subarachnoid hemorrhage (aSAH) without further complication (SAHw/o/c). ⋯ CSFIL-6 is increased after aSAH in patients with cVSSAH or VCSAH. Patients with a CSFIL-6 level higher than a C-OFF of 3100 pg/mL have an increased likelihood for VCSAH; patients with CSFIL-6 levels between 530 and 3100 pg/mL have an increased posttest probability for cVSSAH.
