Introduction: Intramedullary spinal cord tumors (IMSCTs) are rare but clinically significant entities that may cause severe neurological decline with progressive pain and motor or sensory deterioration. Beyond the beneficial effects of surgical treatment and the long-term progression-free survival, neurological deficits may still persist after surgery, and information about the long-term patients' health-related quality of life (QoL) is still lacking. In this study, we investigate the patients' health perception 15 years after the surgery in an overall patients' wellbeing framework.

Previous investigations have reported on the motor benefits and safety of chronic extradural motor cortex stimulation (EMCS) for patients with Parkinson's disease (PD), but studies addressing the long-term clinical outcome are still lacking. In this study, nine consecutive PD patients who underwent EMCS were prospectively recruited, with a mean follow-up time of 5.1 ± 2.

Electric Extradural Motor Cortex Stimulation (EMCS) is a neurosurgical procedure suggested for treatment of patients with advanced Parkinson's disease (PD). We report two PD patients treated by EMCS, who experienced worsening of motor symptoms and cognition 5 years after surgery, when EMCS batteries became discharged. One month after EMCS restoration, they experienced a subjective improvement of motor symptoms and cognition.

Background: In most centers, the surgery of deep brain stimulation (DBS) is performed using a stereotactic frame. Compared with frame-based technique, frameless stereotaxy reduces the duration of surgical procedure and patient's discomfort, with lead placing accuracy equivalent after the learning curve. Although several studies have investigated the targeting accuracy of this technique, only a few studies reported clinical outcomes, with data of short-term follow-up.

Objective: Epilepsy is characterized by unpredictable and sudden paroxysmal neuronal firing occurrences and sometimes evolving in clinically evident seizure. To predict seizure event, small-world characteristic in nine minutes before seizure, divided in three 3-min periods (T0, T1, T2) were investigated.

Methods: Intracerebral recordings were obtained from 10 patients with drug resistant focal epilepsy examined by means of stereotactically implanted electrodes; analysis was focused in a period of low spiking (Baseline) and during two seizures.

Introduction: Motor cortex stimulation (MCS) was introduced by Tsubokawa in 1991 1 for the treatment of thalamic pain, after coming to the conclusion that the hyperactivity of thalamic neurons after spino-thalamic tractotomy was inhibited by stimulation of the motor cortex. MCS has been reported not only to be effective on pain, but also to improve movement disorders such as Parkinson's disease, tremor, dystonia, poststroke movement disorders and hemiparesis. Most of these publications are case reports or small series, and the real impact of MCS on movement disorders remains to be determined.

Objective: Laminectomy has normally been used as a standard approach for intradural spinal tumors but this procedure is associated with spinal instability and deformity. Laminoplasty was developed to overcome these limitations. Controversies still exist regarding its actual role in preventing spinal deformity in adults.

Trigeminal neuralgia (TN) recurring after surgery can be difficult to treat. Treatment algorithms have not been standardized or universally accepted. Here we investigated the effectiveness of percutaneous balloon compression (PBC) in the treatment of patients with TN recurrence after other surgical techniques and analyzed the role of some clinical and operative factors in determining the prognosis.

Pleomorphic xanthoastrocytoma (PXA) is a rare tumor with good prognosis after surgery. Few cases of anaplastic PXA (either de novo or secondary to transformation of a recurrent low grade PXA) have been reported. Moreover, primary anaplastic PXA with dissemination at diagnosis has been described only in two patients, to our knowledge.

Objective: Drug-resistant trigeminal neuralgia (TN) can complicate the clinical course of patients affected by multiple sclerosis (MS). Various surgical procedures have been reported for the treatment of this condition, but there is no agreement on the best management of these patients. To our knowledge, there is no critical literature analysis focusing on this particular topic.

Background: The primary motor cortex, which is part of the corticobasal ganglia loops, may be an alternative option for the surgical treatment of Parkinson disease.

Objective: To report on the 1-year safety and efficacy of unilateral extradural motor cortex stimulation in Parkinson disease.

Methods: A quadripolar electrode strip was extradurally implanted over the motor cortex.

Objective: The objective of this study was to assess striatal dopamine transporter availability in patients with advanced Parkinson's disease (PD) before and after 13 months of unilateral extradural motor cortex stimulation (EMCS) with [123I]N-ω-fluoropropyl-2-β-carbo-methoxy-3-β-(4-iodophenyl)nortropane single photon emission computed tomography (123I-FP-CIT SPECT).

Methods: Six PD patients (five women and one man, aged 63.2 ± 5.

Background: The role of different procedures for the treatment of drug-resistant trigeminal neuralgia (TN) in patients affected by multiple sclerosis (MS) is under discussion and there are no clear indications in the literature. In particular, the role of percutaneous balloon compression (PBC) has been poorly addressed so far. Moreover, to the best of our knowledge, there are no reports analysing the factors potentially related to the prognosis in these patients.

Spinal cord stimulation (SCS) is believed to be effective in treating refractory angina. The need for SCS-related chest paresthesia, however, has hitherto made impossible placebo-controlled trials. Subliminal (non paresthesic) SCS, however, might be also effective on anginal pain.

Background: Motor cortex stimulation has been proposed for treatment of amyotrophic lateral sclerosis (ALS) and preliminary studies have reported a slight reduction of disease progression using both invasive and noninvasive repetitive stimulation of the motor cortex.

Objective: The aim of this proof of principle study was to investigate the effects of motor cortex stimulation performed for a prolonged period (about 2 years) on ALS progression.

Methods: Two patients were included in the study; the first patient was treated with monthly cycles of repetitive transcranial magnetic stimulation (rTMS) and the second one was treated with chronic epidural motor cortex stimulation.

In a primate model of Parkinson's disease (PD), the benefit of extradural motor cortex stimulation (EMCS) was associated with high-frequency stimulation (130 Hz), whereas no significant motor improvement was achieved at 10 Hz or intermediate frequencies of stimulation. We report the case of a 72-year-old female patient affected by severe PD who underwent bilateral EMCS. In baseline med-off condition the patient was unable to arise from a chair and to stand without assistance.

Objective: To assess the long-term effect of spinal cord stimulation (SCS) in patients with refractory cardiac syndrome X (CSX).

Methods: A prospective, controlled, long-term follow-up was performed of 19 patients with CSX with refractory angina who underwent SCS (SCS group, 5 men, mean (SD) age 60.9 (8.

Background And Purpose: Preliminary studies suggest that electrical stimulation of the damaged cortex may be able to enhance motor recovery after stroke. The hypothesis has been that this increases cortical excitability, making it easier for the system to respond to and learn from conventional physiotherapy. However, there is no direct evidence that the cortex of patients with stroke can respond in this fashion; hence, the basis of these new approaches has been questioned.

Oscillatory activity in the beta (beta)-frequency band (13-35 Hz) can be recorded over the sensorimotor cortex in humans. It is coherent with electromyographic activity (EMG) during tonic contraction, but whether the cortical beta-oscillations are primarily motor or sensorimotor in function remains unclear. We tested the hypothesis that cortical beta-activity is associated with an up-regulation of sensory inputs that may be relevant to the organization of the motor response.
