Treatment of dystonia should be individualized and tailored to the specific needs of patients. Surgical treatment is an important option in medically refractory cases. Several issues regarding type of the surgical intervention, targets, and predict factors of benefit are still under debate. Areas covered: To date, several clinical trials have proven the benefit and safety of deep brain stimulation (DBS) for inherited and idiopathic isolated dystonia, whereas there is still insufficient evidence in combined and acquired dystonia...

Thong Pham, Jeffrey Wesolowski, Jonathan D Trobe
Purpose: To report an unusual case of vertebrobasilar dolichoectasia causing both trigeminal neuralgia and ipsilateral sixth cranial nerve palsy. Observations: A patient had undergone surgical decompression of trigeminal neuralgia caused by dolichoectatic vertebral and basilar arteries years before presenting with ipsilateral sixth nerve palsy. Brain MRI showed deviant vertebrobasilar arteries that presumably now compressed the sixth cranial nerve. The unaffected left sixth cranial nerve was visible on MRI, but the affected right sixth cranial nerve was not...

A 43-year-old man was operated on for right frontal oligoastrocytoma. 14 years after the surgery, magnetic resonance imaging and positron emission tomography revealed a new lesion near the surgical cavity. He underwent gross total resection of the lesion and implantation of bis-chloroethylnitrosourea (BCNU) wafers after intraoperative pathological diagnosis of recurrent high-grade glioma. A few days after the operation, the level of consciousness gradually worsened and left hemiparesis developed. A computed tomography scan revealed a cyst remote to the surgical cavity which did not exist 3 days prior...

Stroke is a leading cause of death and a major contributor to neurological disability in adults. Tissue plasminogen activator is the only approved treatment. However, due to its narrow therapeutic window, <5% of patients receive treatment. Recently, hypoxic postconditioning (HPC) was shown to reduce stroke induced-injury in mice, but the mechanisms and functional outcomes are still unknown. In the current study, male Sprague Dawley rats were subjected to endothelin-1 induced stroke. HPC (8% O2 , 1 h/d for 5d) or normoxia treatments were started 24 h after stroke...

Arachnoid cysts are a relatively common finding in adult patients, especially with the advent of advanced imaging techniques. The overall incidence ranges from 1-2%, and the majority are clinically silent1,2 . Arachnoid cysts are postulated to arise by congenital anomalies or trauma1 . De novo formation of arachnoid cysts has been reported, but is exceptionally rare and mostly found in the pediatric population after head trauma3-5 . There have only been two reported cases of symptomatic de novo arachnoid cyst formation in adult patients to date, both with histories of head trauma6,7 ...

OBJECTIVE Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has become standard care for the surgical treatment of Parkinson's disease (PD). Reliable interpretation of microelectrode recording (MER) data, used to guide DBS implantation surgery, requires expert electrophysiological evaluation. Recent efforts have endeavored to use electrophysiological signals for automatic detection of relevant brain structures and optimal implant target location. The authors conducted an observational case-control study to evaluate a software package implemented on an electrophysiological recording system to provide online objective estimates for entry into and exit from the STN...

The role of local treatment in patients with oligometastatic non-small-cell lung cancer (NSCLC) is a subject of ongoing debate. This study assessed the survival impact of combined surgery to the primary tumor and metastatic disease in the management of metastatic NSCLC. Stage IV NSCLC patients at presentation, diagnosed from 2004 to 2013 were identified from the SEER (Surveillance, Epidemiology, and End Results) database. Propensity-matched analysis was performed considering baseline characteristics (age, gender, race, histology, TN stage, and site of metastases)...

The prognosis of glioma remains poor because of the infiltrative nature and the high local relapse rate. The current goals for patients with gliomas is maximal safe resection and adjuvant therapy. Tumor-specific photosensitizer, such as hematoporphyrin derivative (HpD) 5-aminolevulinic acid (5-ALA), can be selective up-taken and accumulated in tumor tissue. Light with appropriate wavelength can penetrate tumor tissue and excite the photosensitizer. The excited photosensitizer within glioma cells permits fluorescence visualization of tumor tissue during surgery and has been introduced in treatment of glioma as fluorescence-guided surgery (FGS)...

Objective: Despite recent advances in medicine, no significant improvement has been achieved in therapeutic outcomes for severe traumatic brain injury (TBI). In the treatment of severe multiple traumas, accurate judgment and prompt action corresponding to rapid pathophysiological changes are required. Therefore, we developed the "All-in-One" therapeutic strategy for severe TBI. In this report, we present the therapeutic concept and discuss its efficacy and limitations. Methods: From April 2007 to December 2015, 439 patients diagnosed as having traumatic intracranial injuries were treated at our institution...

Glioblastoma (GBM) is one of the most aggressive malignant tumors with an overall dismal survival averaging one year despite multimodality therapeutic interventions including surgery, radiotherapy and concomitant and adjuvant chemotherapy. Few drugs are FDA approved for GBM, and the addition of temozolomide (TMZ) to standard therapy increases the median survival by only 2.5 months. Targeted therapy appeared promising in in vitro monolayer cultures, but disappointed in preclinical and clinical trials, partly due to the poor penetration of drugs through the blood brain barrier (BBB)...

REVIEW
Hua Gao, Chunhui Liu, Yazhuo Zhang
The endoscope has traditionally been used in neurosurgery to access a lesion within a natural body cavity. The challenge has been to access and resect deep-seated intraparenchymal lesions using a minimally invasive endoscopic technique. Endoscopic endonasal trans-sphenoidal surgery has gained increasing acceptance by otolaryngologists and neurosurgeons. Surgical procedures of the skull base include exposure, resection, and base reconstruction. These approaches start at the sphenoid sinus, which provides a reference point to important vascular and neural structures...

Patients who undergo surgical resection of brain metastases are at significant risk of cavity local recurrence without additional radiation therapy. Postoperative stereotactic radiosurgery (SRS) is a method of focal treatment to the cavity to maximize local control while minimizing the risk of neurocognitive detriment associated with whole brain radiation therapy. Recently published randomized trials have demonstrated the benefit of postoperative SRS in terms of cavity tumor control and preserving neurocognition...
