Review Case Reports
Deep Brain Stimulation of the Caudal Zona Incerta/Motor Thalamus for Post-Ischemic Dystonic Tremor of the Left Upper Limb. Case Report and Review of the Literature.
Dystonic tremor is defined as a tremor occurring in a body region affected by dystonia. The pathophysiologic mechanisms behind dystonic tremor supposedly involve anomalies affecting the pallidothalamic-receiving area (for the dystonic component) and the ventralis intermedius-cortical loop (for the tremor component). Interest in posterior subthalamic area stimulation for various types of involuntary abnormal movements has arisen owing to positive results in patients affected by tremor refractory to ventralis intermedius deep brain stimulation. ⋯ Stimulation of motor thalamus and caudal zona incerta could be a viable treatment for patients affected by tremor of various origins, including dystonic tremor, refractory to medical therapy.

Review Case Reports
"Intramedullary capillary hemangioma presenting with hydrocephalus and spastic paraparesis in a two-month-old infant".
Intramedullary capillary hemangiomas are rare lesions with only 14 cases reported so far and are found in middle-aged persons. Until now only a single case has been reported in the pediatric population. Ours was the second pediatric case and the youngest of all to be diagnosed with an intramedullary capillary hemangioma. ⋯ Intramedullary capillary hemangiomas are extremely rare lesions in infants but should be kept in mind while treating any patient with the spinal lesion. Further reporting of similar cases will help in understanding the natural history, pathogenesis, and management.

Brain metastases occur in a large portion of patients with cancer. Although advances in radiotherapy have helped to improve survival, they have also raised questions regarding the best modality for retreatment in the context of recurrent disease. ⋯ We have comprehensively reviewed the existing data on the efficacy and toxicity of the various reirradiation treatment modalities. We examined the key clinical considerations that guide patient selection, such as dose, tumor size, interval to retreatment, and local control and survival rates.

Historical Article
Great Hospitals in North America: The Medical College of Wisconsin Neurological Surgery.
The Medical College of Wisconsin Department of Neurosurgery delivers subspecialty adult and pediatric neurosurgical care that is patient-centered, evidence-informed, and value-based. Medical College of Wisconsin research advances the science of neurological disease with the goal of a positive translational effect on clinical care. ⋯ The journey to become a neurosurgical center of excellence was accomplished with the leadership and foresight of the men and women who turned their dreams into reality. The establishment and rise of the department as a national force for neurosurgery and spine is an elegant example of the combination of individual leadership and foresight with synergistic institutional support.

Self-locking stand-alone cages can achieve satisfactory clinical results and fusion rate. However, there have been no reports on the causes and relationship of different fusion state. This study is to classify the different fusion states of the index level and to explore the potential contributing factors and links of them. ⋯ For anterior cervical discectomy and fusion with self-locking stand-alone cages, the fusion of the index level seems to be a progressive dynamic process during the mid-term follow-up, which may be influenced by the location of the cage, the aagittal vertical axis of the index level, and the global range of motion of the cervical spine. Satisfactory clinical results could be achieved by all the fused types.
