Background: Resection of gliomas in or adjacent to the motor system is widely performed using intraoperative neuromonitoring (IOM). Despite the fact that data on the safety of IOM are available, the significance and predictive value of the procedure is still under discussion. Moreover, cases of false negative monitoring affect the surgeon’s confidence in IOM.
Objective: To examine cases of false negative IOM to reveal structural explanations.
Methods: Between 2007 and 2010 we resected 115 consecutive supratentorial gliomas in or close to eloquent motor areas using direct cortical stimulation for monitoring of motor evoked potentials (MEPs). The monitoring data were reviewed and related to new postoperative motor deficit and postoperative imaging. Clinical outcomes were assessed during follow-up.
Free Article: Awake Craniotomy vs Surgery Under General Anesthesia for Resection of Supratentorial Lesions
BACKGROUND: The use of an awake craniotomy in the treatment of supratentorial lesions is a challenge for both patients and staff in the operation theater.
OBJECTIVE: To assess the safety and effectiveness of an awake craniotomy with brain mapping in comparison with a craniotomy performed under general anesthesia.
METHODS: We prospectively compared 2 groups of patients who underwent surgery for supratentorial lesions: those in whom an awake craniotomy with intraoperative brain mapping was used (AC group, n = 214) and those in whom surgery was performed under general anesthesia (GA group, n = 361, including 72 patients with lesions in eloquent areas). The AC group included lesions in close proximity to the eloquent cortex that were surgically treated on an elective basis.

BACKGROUND: Sacral agenesis is an uncommon congenital disorder that involves multiple organs.
OBJECTIVE: We studied neurological manifestations of the disease, common associated disorders, and their relation with extent of bony malformation.
METHODS: We investigated neurological manifestations of 50 patients with sacral agenesis. Patients were evaluated for previous procedures, ambulation, limb abnormalities, vertebral alignment, recurrent urinary tract infection, urinary incontinence, dribbling, dimple, lower extremities weakness, myelomeningocele (MMC), and lipomyelomenangocele.
