Stereotactic radiosurgery for patients with trigeminal neuralgia associated with petroclival meningiomas.
The management of trigeminal neuralgia in patients with associated skull base meningiomas is complex. ⋯ SRS provided effective tumor control, but trigeminal neuralgia persisted to varying degrees in most patients. Multimodality pain management strategies were required in most patients with skull base meningiomas associated with trigeminal neuralgia.

A combination procedure with double C-shaped skin incision and dual-floor burr hole method to prevent skin erosion on the scalp and reduce postoperative skin complications in deep brain stimulation.
The purpose of this study was to introduce a combination procedure with double C-shaped skin incision and an adjusted dual-floor burr hole to prevent skin complications on the scalp with deep brain stimulation (DBS) surgery. ⋯ The combination procedure prevents skin complications associated with DBS surgery, with tensile strength, less impaired vascular supply and better cosmetic outcome. This promising approach prevents unwanted skin complications associated with DBS surgery and improves patient satisfaction.

Cortical areas involved in numerical processing: an intraoperative electrostimulation study.
Numerical processing is important in our everyday lives. However, very few attempts have been made to map the numerical processing function areas during lesion surgery. ⋯ To improve the quality of resection while minimizing the neurological deficits, functional boundaries of numerical processing areas should be considered during the removal of a parietal low-grade glioma. Moreover, only the left intraparietal sulcus is necessary for numerical processing, whereas the right intraparietal sulcus does not appear to be critically involved in numerical processing.

Case ReportsPain relief and functional recovery in patients with complex regional pain syndrome after motor cortex stimulation.
In addition to pain and neurovegetative symptoms, patients with severe forms of complex regional pain syndrome (CRPS) develop a broad range of symptoms, including sensory disturbances, motor impairment and dystonic posturing. While most patients respond to medical therapy, some are considered refractory and become surgical candidates. To date, the most commonly used surgical procedure for CRPS has been spinal cord stimulation. ⋯ In the long term (27 and 36 months after surgery), visual analog scale pain scores were improved by 60-70% as compared to baseline. There was also a significant increase in the range of motion in the joints of the affected limbs and an improvement in allodynia, hyperpathia and hypoesthesia. Positron emission tomography scan in both subjects revealed that MCS influenced regions involved in the circuitry of pain.

Case ReportsA technique of distal to proximal revision of peripheral neurostimulator leads: technical note.
Peripheral nerve stimulation for chronic pain states is a safe and efficacious technique, being used with increasing frequency. The incidence of hardware-related complications requiring revision remains high. ⋯ The distal to proximal neurostimulator lead revision technique quickly and safely adjusts lead position, including both lead depth and lead tip location, without a need for replacement of components or revision of the entire system.
