Intraoperative Neurophysiological Monitoring in Syringomyelia Surgery: A Multimodal Approach.

Syringomyelia can be associated with multiple etiologies. The treatment of the underlying causes is first-line therapy; however, a direct approach to the syrinx is accepted as rescue treatment. Any direct intervention on the syrinx requires a myelotomy, posing a significant risk of iatrogenic spinal cord (SC) injury.

Diagnosis and treatment of trigeminal neuralgia: Consensus statement from the Spanish Society of Neurology's Headache Study Group.

Introduction: Trigeminal neuralgia (TN) is a chronic neuropathic pain disorder affecting one or more branches of the trigeminal nerve. Despite its relatively low global prevalence, TN is an important healthcare problem both in neurology departments and in emergency departments due to the difficulty of diagnosing and treating the condition and its significant impact on patients' quality of life. For all these reasons, the Spanish Society of Neurology's Headache Study Group has developed a consensus statement on the management of TN.

Theoretical insight on the treatment of β-hexachlorocyclohexane waste through alkaline dehydrochlorination.

The occurrence of 4.8-7.2 million tons of hexachlorocyclohexane (HCH) isomers stocked in dumpsites around the world constitutes a huge environmental and economical challenge because of their toxicity and persistence.

A rare case of an intramedullary metastasis of a myxopapillary ependymoma.

Background: Myxopapillary ependimoma (MPE) is a benign slow-growing tumor, and it has been designated histologically as a Grade I neoplasm according to the 2016 World Health Organization classification. Despite the benign character, dissemination and metastasis have occasionally been reported. The retrograde dissemination to other levels of the neuraxis is extremely rare, being more frequent to the intracranial compartment.

[Treatment of trigeminal neuralgia: an update and future prospects of percutaneous techniques].

Introduction: Trigeminal neuralgia is one of the most severe facial pain syndromes. The annual incidence varies between 4-13% and has a significant effect on patients' quality of life. When the pain cannot be controlled by pharmacological treatment, several different surgical options can be considered.

Deep Brain Stimulation Influences Brain Structure in Alzheimer's Disease.

Background: Deep Brain Stimulation (DBS) is thought to improve the symptoms of selected neurological disorders by modulating activity within dysfunctional brain circuits. To date, there is no evidence that DBS counteracts progressive neurodegeneration in any particular disorder.

Objective/hypothesis: We hypothesized that DBS applied to the fornix in patients with Alzheimer's Disease (AD) could have an effect on brain structure.

[Posterior spinal instrumentation image guided and assisted by neuronavigation. Experience in 120 cases].

Introduction: The authors present the results of a series of 121 cases of posterior vertebral fixation carried out from Sept 2008 to Sept 2010 using Flouro 2D-TC assisted Vector Vision o Kolibri navigator. ( Brain LAB, Feldkirchen, Germany).

Material: The sample included 68 males and 53 females.

[Posterior C1-C2 arthrodesis. Experience in transarticular and interarticular fixation in 36 patients].

Objective: The stabilization of C1-C2 segment has evolved with the appearance of several techniques from sublaminar, transarticular or interarticular fixation and over recent years with the introduction of neuronavegation systems. The aim of the study was to review patients treated in our center with transarticular and interarticualr fixation and compare the results obtained with both techniques.

Methods: Thirty six patients with C1-C2 instability that required a surgical fixation between 1995-2008 were retrostpectively analized.

[Comparison [corrected] of Chiari I malformation treatment using suboccipital craniectomy and posterior arch of C1 resection with or without dural graft].

Unlabelled: There are various surgical approaches to treat Chiari I malformation. In spite of the good clinical results that are reported with most of them, there is still controversy about the optimal treatment of this pathology.

Objective: To compare the clinical and radiological results of surgical treatment of the Chiari I malformation with suboccipital craniectomy, posterior arch of C1 resection with or without dural graft, analyzing clinical and radiological findings and describing the complications.
