Comparative Analysis of Hemispherotomy in Adults versus Children- A Prospective Observational Series.

Background: Hemispherotomy (HS) is an effective treatment for unilateral hemispheric onset epilepsy. There are few publications for HS in adults, and there is no series comparing adults and pediatric patients of HS.

Objective: To compare the hemispherotomies done in adult patients with pediatric ones in terms of efficacy and safety.

Case report on ear numbness following deep brain stimulation implantation.

Introduction And Importance: Deep brain stimulation (DBS) implantation is a neurosurgical procedure in which electrodes are implanted in the brain. Complications that may occur include wound infection, issues with the DBS hardware, and others. This case report presents a patient who suffered ear numbness following DBS implantation.

The Effect of Intrathecal Injection of Dextromethorphan on the Experimental Neuropathic Pain Model.

Background: Peripheral glucocorticoid receptors (GRs) are altered by peripheral nerve injury and may modulate the development of neuropathic pain. Two central pathogenic mechanisms underlying neuropathic pain are neuroinflammation and N-methyl-D-aspartate receptor (NMDAR)-dependent neural plasticity in the spinal cord.

Objectives: This study examined the effect of the non-competitive NMDAR antagonist dextromethorphan on partial sciatic nerve ligation (PSL)-induced neuropathic pain and the spinal expression of the glucocorticoid receptor (GR).

Chronic subdural hematoma-induced parkinsonism: A systematic review.

Background: Chronic subdural hematoma (CSDH) is one of the most common neurosurgical cases, especially in elderly individuals. Secondary parkinsonism due to CSDH is a rare entity. The mechanism of parkinsonism symptoms in chronic subdural hematoma has been suggested to include direct mechanical compression of the basal ganglia due to hematoma or indirectly through brain structure changes due to space lesions and vascular disorders.

Robotic-Guided Stereoelectroencephalography for Refractory Epilepsy: Technique and Nuances.

Background: Stereoelectroencephalography (SEEG) has become an integral part of epilepsy surgery, often used in the localization of the epileptogenic zone. It is an essential modality not only in the evaluation of nonlesional but also lesional drug refractory epilepsy, especially in the presence of anatomo-electro-clinical discordance.

Objective: To describe our technique and the operative nuances involved in the performance of robotic SEEG placement.

VIM Line Technique for Determining the Ventral Intermediate Location.

Aim: To prove that VIM line technique created by using a mathematical model, can be used to identify the location of the ventral intermediate nucleus of the thalamus (VIM) MATERIAL and METHODS: Eleven patients with Parkinson?s disease (PD) were assessed. To determine the VIM location, 3-T magnetic resonance imaging and stereotactic protocol 128-slice computed tomography were used. The VIM line technique was performed by drawing a line from the end-point of the right external globus pallidus to that of the left external globus pallidus in the intercommissural plane.

Complete resolution of recurrent piriformis syndrome after piriformis resection with 3 years' follow up: A case report.

Introduction: Piriformis syndrome (PS) is an uncommon neuromuscular condition characterized by buttock pain radiating to the leg. Although the goal of PS treatment is symptom relief, it is difficult in some patients using conservative treatment alone.

Presentation Of Case: A 72-year-old male underwent piriformis resection after failed sequential steroid injection of the piriformis.

Vim line technique thalamotomy for Parkinson tremor: Case series.

Introduction: The ventral intermediate (Vim) nucleus of the thalamus is difficult to identify even with 3 T magnetic resonance imaging. Stereotactic Vim thalamotomy is a usual procedure to control Parkinson tremor. Successful relieving of the tremor depends on the accuracy of defining the Vim location.

Successful Relief of Abdominal Dystonia After Sequential GPi Pallidotomy with 2-Year Follow-Up.

Background: Abdominal dystonia is very rare. To our knowledge, no clinical study has reported its specific treatment. Stereotactic therapy has been used to treat several movement disorders, including focal and general dystonia.

Stereotactic aspiration of spontaneous intracerebral hematoma: Case series.

Introduction: Minimally invasive techniques such as stereotactic aspiration of spontaneous intracerebral hematoma (SICH) evacuation can minimize brain tissue damage due to surgery. We share our experience of adopting stereotactic aspiration of SICH in our center without compromising safety.

Presentation Of Cases: Three stereotactic aspiration procedures for SICH immediately after 24 h of onset are reported.

Endoscope-assisted (with robotic guidance and using a hybrid technique) interhemispheric transcallosal hemispherotomy: a comparative study with open hemispherotomy to evaluate efficacy, complications, and outcome.

OBJECTIVEEndoscope-assisted hemispherotomy (EH) has emerged as a good alternative option for hemispheric pathologies with drug-resistant epilepsy.METHODSThis was a prospective observational study. Parameters measured included primary outcome measures (frequency, severity of seizures) and secondary outcomes (cognition, behavior, and quality of life).

Impar Ganglion Block with Combination of Neurolysis Drugs and Radiofrequency Thermocoagulation for Perineal Pain.

Since it was first introduced, a variety of modification techniques to block the impar ganglion appear such as transsacrococcygeal ligament technique, sacrococcygeal transdiscal approach, paramedian approach, and a two-needle technique using fluoroscopy or computed tomography scan. For therapeutic purposes, a combination of steroid and local anesthetic, neurolysis agents such as alcohol, phenol, cryolesioning, and heat lesioning using radiofrequency thermocoagulation could be used. Here, we reported a successful outcome in treating chronic perineal pain in a 65-year-old patient using combination of neurolysis agent which was alcohol 96% and radiofrequency thermocoagulation.

Stereotactic Radiofrequency Thermocoagulation of Hypothalamic Hamartoma Using Robotic Guidance (ROSA) Coregistered with O-arm Guidance-Preliminary Technical Note.

Introduction: Treatment options for hypothalamic hamartoma (HH) include microvascular surgery, stereotactic radiofrequency thermocoagulation (SRT), laser interstitial thermal therapy, or Gamma Knife surgery. During SRT, thermographic monitoring cannot be performed and therefore highly accurate placement of electrode and confirmation of its position are required. We have used robotic guidance (ROSA) and coregistered it with O-arm for performing ablation of hamartoma.
