Gilles de la Tourette syndrome (GTS) is a chronic neurodevelopmental disorder characterized by tics and associated behavioral symptoms. Over the past decade, deep brain stimulation (DBS) has been increasingly advocated as a reversible and controllable procedure for selected cases of GTS. ⋯ DBS is a promising treatment option for severe cases of GTS. There is a need to reach consensus on the definition of "treatment-refractoriness" and to conduct larger double-blind randomized controlled studies on the most promising targets.

Review Case Reports
Thoracic myelopathy due to an intramedullary herniated nucleus pulposus: first case report and review of the literature.
Herniation of intervertebral discs is relatively common. Migration usually occurs in the ventral epidural space; very rarely discs migrate in the subdural space. No cases of intradural intramedullary disc have been reported in humans. ⋯ Intradural intramedullary migration of a herniated intervertebral disc is extremely rare but should be considered in the differential. It may present in a variety of clinical scenarios, including thoracic myelopathy, and mimic intramedullary spinal cord tumor.

The management of spinal column tumors continues to be a challenge for clinicians. The mechanisms of tumor recurrence after surgical intervention as well as resistance to radiation and chemotherapy continue to be elucidated. Furthermore, the pathophysiology of metastatic spread remains an area of active investigation. ⋯ The purpose of this review is to discuss what is known about the role of CSCs in tumors of the osseous spine. First, this article reviews the fundamental concepts critical to understanding the role of CSCs with respect to chemoresistance, radioresistance, and metastatic disease. This discussion is followed by a review of what is known about the role of CSCs in the most common primary tumors of the osseous spine.

Review Case Reports
Intracerebral abscess associated with the Camino intracranial pressure monitor: case report and review of the literature.
Intracranial pressure (ICP) monitoring is a mainstay in the management of traumatic brain injury. Large investigations have validated the safety and efficacy of ICP monitors in comatose patients. Clinically relevant infections are extremely rare and cerebral abscess has never been reported with the Camino device. We describe an exceptional case of a life-threatening intracerebral abscess from an intraparenchymal ICP monitor. ⋯ To the best of our knowledge, this is the first report describing an intracerebral abscess as a complication from an intraparenchymal pressure monitor. Corticosteroid therapy may have constituted an independent risk factor for the ICP monitor--associated infection, as well as reinsertion of the ICP monitoring device at the same site. That this is the first reported parenchymal infectious complication underscores the safety of this device with respect to infection. When reinsertion of a parenchymal monitor is considered, a new site should be chosen.
