Randomized Controlled Trial
The outcome predictors of Malignant Large Infarction and the Functional Outcome of Survivals Following Decompressive Craniectomy.
Cerebral infarction is a common cause of disability. Malignant large infarction (MLI) is a catastrophic event, and there is no effective medical treatment. This study aimed to assess the outcome predictors of MLI and to analyze the impact of decompressive craniectomy (DC) on the functional outcome of survivors. ⋯ In this study, DC performed on a young patient with motor response of localizing pain or better was linked with a better outcome. DC not only reduced mortality and increased the number of good survivals but also, most importantly, decreased the number of poor functional outcome survivals.

Multicenter Study
Surgeon and patient's radiation exposure through vertebral body cement augmentation procedures: a prospective multicentric study of 49 cases.
Vertebral body cement augmentation as a treatment option for osteoporotic or traumatic fractures has become increasingly popular during the past decade. However, these surgical procedures require numerous fluoroscopic examinations, resulting in high radiation exposure for the patient and the surgical team. The aim of this study was to evaluate the level of radiation exposure of the spine surgeon and the patient during these percutaneous procedures. ⋯ Values of radiation doses for surgeon and patient were lower than those reported in the previous literature. The recommended annual dose limit is set to 500 mSv for extremities and 150 mSv for lens. According to our results, the exposure dose to the eye exceeds the annual limit after 3500 procedures. However, there is increasing concern among surgeons about radiation exposure, and there is still a need for solutions as preventive measures.

Although intraoperative magnetic resonance imaging (iMRI) increasingly is used during glioma resection, its role in skull base surgery has not been well documented. In this study, we evaluate our experience with iMRI for skull base surgery. ⋯ Despite the unique challenges associated with skull base tumor surgery, iMRI can be safely obtained while adding a modest although not prohibitive amount of time to the procedure. The immediate evidence of residual tumor with a patient still in position to have additional resection may influence the surgeon to alter the surgical plan and attempt further resection in a critical area.

The place of stereotactic biopsies in the management of diffuse intrinsic pontine gliomas (DIPGs) in children has changed over the years. Nonetheless, stereotactic biopsy remains a surgical procedure with its risks. One complication that has not been reported previously in case of a biopsy of a DIPG is metastatic seeding along the tract of the biopsy. We report the first 2 cases in the literature. ⋯ The era of targeted therapy with molecular and genomic discoveries has paved the way to a research protocol that requires a biopsy from the patient. The reported complications have never been described before. The purpose of this paper is not to suggest that no biopsy should be performed when a DIPG is suspected. For now, biopsy remains investigational, because no benefit in survival could be drawn so far for any patient. This subject deserves honest discussion with the children and their parents.

To evaluate whether preoperative multirow detector computed tomography (MDCT) findings were associated with clinical outcome 24 months after dynamic stabilization for painful degenerative lumbar spine disease. ⋯ Clinical improvement after dynamic stabilization was significantly associated with 7 independent baseline imaging findings. Preoperative evaluation of these MDCT parameters may improve therapy selection for patients with degenerative lumbar spine disease.
