Assessment of bias showed that most of the studies had low risk of biases and sensitivity analysis for bias did not change these results. Effect sizes vary from 0.01 to 0.70 and were significant in about 8 conditions, with largest effect size being in postoperative acute pain, and smaller in stroke motor recovery (nonsignificant when combined with robotic therapy). All recommendations listed here are based on current published Pubmed-indexed data. Despite high level of evidence in some conditions, it needs to be underscored that effect sizes and duration of effects are often limited; thus, real clinical impact needs to be further determined with different study designs.All recommendations listed here are based on current published Pubmed-indexed data.

It has opened up entries for large scale comparative genome studies, especially the identification of conserved syntenic blocks among the species, facilitating the evolutionary importance of the conservation and variation in genomic organization. Synteny construction and visualization requires computational and bioinformatics skills to prepare input file for the synteny analysis pipeline. The syntenic information in fishes is still in juvenile stage and are scattered in different research domains. Here, we present a web-based tool 'Evol2Circos' to provide a user-friendly GUI- and web-based tool to analyse user specific data for synteny construction and visualization, and to facilitate the browsing of syntenic information of different fishes using the circos, bar, dual and dot plots. The information generated from the tool can also be used for further downstream analyses. Evol2Circos software tool is tested under Ubuntu Linux. The web-browser, source code, documentation, user manual, example dataset and scripts are available online at 203.190.147.148/evole2circos/. Accurate screw placement remains very challenging especially in the upper cervical spine. To present our first experience of a percutaneous posterior C1-C2 fixation for a traumatic fracture. This is a case report of a non-neurological patient, harboring a type II odontoid fracture. She underwent a posterior percutaneous fixation using Cirq® Robotic Assistance coupled to the AIRO® intraoperative computed tomography (iCT)-scan and BrainLab® navigation system (all by BrainLab AG). Routine CT was performed on postoperative day 2 to evaluate pedicle screw placement. The effective dose was calculated. The C1-C2 posterior percutaneous fixation was performed with cannulated VERTEX® Reconstruction System (Medtronic). Overall, 4 screws were placed. All of them were rated as acceptable (100%). Radiation dose received by the patient was 4.13 mSv. Radiation dose received by the surgical staff was 0 mSv. Postoperative course was excellent. Posterior percutaneous fixation using Cirq® Robotic Assistance coupled with iCT navigation system is a major innovation that can improve pedicle screw positioning's accuracy with acceptable patient radiation and reduced surgical team exposure.Posterior percutaneous fixation using Cirq® Robotic Assistance coupled with iCT navigation system is a major innovation that can improve pedicle screw positioning's accuracy with acceptable patient radiation and reduced surgical team exposure.Solitary fibrous tumors (SFTs) are uncommon mesenchymal lesions originally described as pleura-based neoplasms. Intradural juxtamedullary SFTs are rare, hard, and scarcely vascularized and generally present a conspicuous extramedullary exophytic component without dural attachment and nerve root involvement. Gross-total resection is the mainstay of treatment, although the absence of an arachnoidal plane and the firm adherence to the spinal cord make resection challenging.  We describe the case of a 74-yr-old female patient presenting with a history of progressive spastic tetraparesis due to a cervical juxtamedullary SFT. NDI091143 The patient was not able to walk and magnetic resonance imaging (MRI) of the cervical spine demonstrated a possible intramedullary lesion at C2-C3 with homogeneous enhancement after gadolinium injection. Given the progressive nature of symptoms, the patient elected to have surgical resection of the tumor. The patient underwent C2-C3 laminoplasty and tumor resection under neurophysiologic monitoring. The tumor presented extremely hard without dural attachment or nerve root involvement and was progressively debulked using microsurgical techniques and ultrasonic aspirator. The identification of a plane between the mass and the spinal cord white matter allowed for a gross total resection. Permanent pathological analysis eventually demonstrated SFT. The patient's neurological condition was unchanged postoperatively. MRI performed 2 mo after the operation demonstrated gross total resection of the lesion. At the 6-mo follow-up visit, the patient was able to walk with assistance.  The patient signed the Institutional Consent Form to undergo the surgical procedure and to allow the use of her images and videos for any type of medical publications. Percutaneous ablation of the cervical spinothalamic tract (STT) remains a therapeutic remedy for intractable cancer pain. However, it is accompanied by the risk of collateral damage to essential spinal cord circuitry, including the corticospinal tract (CST). Recent studies describe threshold-based mapping of the CST with the objective of motor bundle preservation during intramedullary spinal cord and supratentorial surgery. To assess the possibility that application of spinal cord mapping using intraoperative neuromonitoring in percutaneous cordotomy procedures may aid in minimizing iatrogenic motor tract injury. We retrospectively reviewed the files of 11 patients who underwent percutaneous cervical cordotomy for intractable oncological pain. We performed quantitative electromyogram (EMG) recordings to stimulation of the ablation needle prior to the STT-ablative stage. We compared evoked motor and sensory electrical thresholds, and the electrical span between them as a reliable method to confirm safe electrode location inside the STT.
