016). No statistical significance was observed in the ICP and ONSD values with hypertonic saline infusion. In this swine model, ICP and ONSD showed linear correlation and ICP could be estimated using the formula -80.5+238.2×AON.

In the present study, ultrasound to measure ONSD showed a linear correlation with ICP, although a short delay in returning to baseline levels was observed in the case of sudden ICH relief.

While most DCM research focuses on the spinal cord, widespread reorganization of the brain may occur to compensate for functional impairment. This observational study used diffusion spectrum imaging (DSI) to examine reorganization of cerebral white matter associated with neurological impairment as measured by the modified Japanese Orthopedic Association (mJOA), and severity of neck disability as measured by the Neck Disability Index (NDI) score. A total of 47 patients were included in the cervical spondylosis (CS) cohort 38 patients with DCM (mean mJOA = 14.6, and mean NDI = 12.0), and 9 neurologically asymptomatic patients with spinal cord compression (mJOA = 18, and mean NDI = 7.0). 28 healthy volunteers (HCs) served as the control group. Lower generalized fractional anisotropy (GFA) was observed throughout much of the brain in patients compared to HCs (p less then 0.05). Fiber pathways associated with somatosensory functions, such as the corpus callosum and corona radiata, showed increased quantitative anisotropy (QA) in patients compared to HCs. Correlation analyses further suggested that structural connectivity was enhanced to compensate for neurological dysfunction within sensorimotor regions, where fibers such as the posterior corona radiata had NQA values that were negatively associated with mJOA (p = 0.0020, R2 = 0.2935) and positively associated with NDI score (p = 0.0164, R2 = 0.1889). Altogether, these results suggest that DCM and neurologically asymptomatic spinal cord compression patients tend to have long-term reorganization within the brain, particularly in those regions responsible for the perception and integration of sensory information, motor regulation, and pain modulation.The subdural evacuating port system (SEPS) is a minimally invasive option for treating chronic subdural hematoma (cSDH). Individual case series have shown it to be safe and effective, but outcomes have not been systematically reviewed. We sought to review the literature in order to determine the safety and efficacy of SEPS as a first line treatment for cSDH. A comprehensive literature search for outcomes following SEPS placement as a primary treatment for cSDH was performed. The primary outcome was treatment success, which was defined as a composite of improvement in presenting symptoms and no need for further treatment in the operating room. Additional outcomes included discharge disposition, length of stay (LOS), hematoma recurrence, and complications. A total of 12 studies comprising 953 patients who underwent SEPS placement met the inclusion criteria. The pooled rate of a successful outcome was 0.79 (95% CI 0.75-0.83). Frequency of delayed hematoma recurrence was 0.15 (95% CI 0.10-0.21). The pooled inpatient mortality rate was 0.02 (95% CI 0.01-0.03). Complications rates included 0.02 (95% CI 0.00-0.03) for any acute hemorrhage, 0.01 (95% CI 0.00-0.01) for acute hemorrhage requiring surgery, and 0.02 (95% CI 0.01-0.03) for seizure. SEPS placement is associated with a success rate of 79% and very low rates of acute hemorrhage and seizure.

Cases who are refractory to medical treatment and/or surgery may be managed with GKRS. We aimed to describe the effectiveness of GKRS for high-risk lactotroph adenomas (HRLAs) and LAs that were medically and surgically refractory. We analyzed our series of patients with HRLAs and LAs who were managed with GKRS following failed medical treatment and surgery and who had at least three years of follow-up. A total of 52 patients (22 HRLAs and 30 LAs) were included in the analysis of radiological, endocrine, and clinical outcomes. Radiological control was achieved in 68.2% of subjects in the HRLA group and 96.7% of subjects in the LA group. Hormonal control was achieved in 68.2% of patients in the HRLA group and 80% of patients in the LA group. On univariate analysis, hormonal control was significantly associated with pre-treatment volume (p = 0.007), higher margin dose (p = 0.002) and Ki-67 proliferative index (p = 0.007). Complications involved new pituitary hormone deficiencies in 19.2% of patients and asymptomatic peripheral visual field defect in 1.9% of patients. To the best of our knowledge, this is the first study to examine the effectiveness of GKRS in LAs and HRLAs, with the highest median follow-up in the literature. High hormonal control rate, even in HRLAs, and lower complication rates suggest that GKRS should be part of the techniques for managing treatment refractory LAs.We report the case of a patient who experienced recurrent ipsilateral hemiparesis in the setting of predominantly-uncrossed corticospinal tracts, with concomitant neuronal reorganization of the cortical motor maps, and the presence of aberrant interhemispheric connections. Their presence was supported by our results from diffusion tensor imaging tractography, functional magnetic resonance imaging, and transcranial magnetic stimulation. To our knowledge, this has never been reported before, and provides valuable insights into the mechanisms behind post-stroke motor recovery.Meningiomas rarely progress to malignant variants and there is no consensus regarding the period over which malignant transformation may occur. Here, we report a case of anaplastic meningioma that showed malignant transformation 18 years after gross total resection of benign meningioma in the primary surgery, which may be the longest duration reported to date. Although the recurrence rate is low following total resection of benign meningioma, malignant transformation can rarely occur after a long period as in our case. Long-term follow-up after total resection of benign meningioma is suggested considering the risk of malignant transformation.
