Case Reports
Disconnection Surgery for Intractable Epilepsy with a Structural Abnormality in the Medial Posterior Cortex.
The lesionectomy is a general surgical procedure for treating focal epilepsy resulting from a structural abnormality, but a favorable outcome cannot be achieved in some patients, especially patients whose symptomatogenic zone is located in remote regions. Herein we propose the surgical disconnection of the seizure propagation pathway, which consists of short and long associating fibers linking the epileptogenic zone to the remote symptomatogenic zone, as an effective method of achieving favorable seizure outcomes in patients with posterior cortex epilepsy. ⋯ The current study suggested that assuming the presence of association fibers was an important factor for achieving a favorable outcome in the surgical treatment of posterior cortex epilepsy. Though further study is required, disconnection surgery is recommended as a treatment option for cases in which the epileptogenic zone is located in an eloquent area.

Review Case Reports
Coadjuvant Treatment of Vasospasm in Ruptured Unsecured Cerebral Aneurysms with Aggressive Angioplasty, Intra-Arterial Nimodipine, and Aneurysm Embolization.
Vasospasm is a major cause of morbidity and mortality in patients after aneurysmal subarachnoid hemorrhage. Early treatment of ruptured aneurysms is advocated; delayed intervention complicates the treatment strategy leading to significant vasospasm and poor prognosis. We report an endovascular protocol for occlusion of the unsecured aneurysm and angioplasty for vasospasm in a single session. ⋯ Aggressive endovascular treatment of patients with unsecured ruptured cerebral aneurysm and associated vasospasm is safe and effective.

Glioblastoma evades conventional therapies through a variety of mechanisms, including suppression of the immune system. This immunosuppressive microenvironment provides a potential target for treatment. ⋯ Although immunotherapy has already demonstrated efficacy for a variety of other malignancies, its efficacy in glioblastoma is still unclear. Identifying predictive biomarkers and improving the management of immune-related adverse effects will help to realize the full potential of these therapies.

Catastrophic epilepsy results in severe neurodevelopmental delay in infants because of frequent and/or long seizures. Therefore, consideration of early epilepsy surgery is essential for neurodevelopmental outcome. Once an infant with catastrophic seizures is identified as a surgical candidate, it is important that the surgical plan be carefully defined based on detailed presurgical evidence to minimize surgical complications in this age group. ⋯ Careful consideration of the noninvasive presurgical workup can identify focal onset even in the presence of catastrophic epilepsy with widespread bilateral abnormalities. Single-stage lobar leucotomy for disconnection of the epileptogenic zone can lead to excellent outcome in these patients.

Comparative Study
Minimally Invasive Transforaminal Versus Direct Lateral Lumbar Interbody Fusion: Effect on Return to Work, Narcotic Use, and Quality of life.
Direct lateral (DLIF) and transforaminal (TLIF) lumbar interbody fusions have been shown to produce satisfactory clinical outcomes with significant reduction in pain and functional disability. Despite their increasing use in complex spinal deformity surgeries, there is a paucity of data comparing outcome measures, which this study addresses. ⋯ Both MIS TLIF and DLIF provide long-term improvement in pain andfunctional outcomes, with an overall reduction in postoperative narcotic requirement. However, there was a significantly longer time to return to work and a greater incidence of reoperation in the TLIF cohort compared with the patients who underwent DLIF.
