Spontaneous thalamic hemorrhage has increased in incidence in recent years. Analysis of the characteristics of thalamic hemorrhage was based on the vascular territories of the thalamus. ⋯ The present study proposed a novel anatomic classification of thalamic hemorrhage according to the major thalamic vascular territories.

To evaluate prognostic factors of patients with chordoma through a population-based analysis. ⋯ We report the largest study to date to evaluate prognostic factors of patients with chordoma. Multivariate analysis demonstrated that older age, greater tumor size, and distant metastasis were correlated with decreased survival, whereas surgical resection was correlated with increased survival. Patients receiving radiation therapy also showed decreased survival, likely an indication of the patients' advanced stage of disease, making them poor surgical candidates.

The neurosurgical boot camp has been fully incorporated into U.S. postgraduate education. This is the first implementation of the neurosurgical boot in a developing country. To advance neurosurgical education, we developed a similar boot camp program, in collaboration with Bolivian neurosurgeons, to determine its feasibility and effectiveness in an international setting. ⋯ The first South American neurosurgical boot camp had significant value and was well received in Bolivia. This humanitarian model provides a sustainable solution to education needs and should be expanded to other regions as a means for standardizing the core competencies in neurosurgery.

The goal of treatment for spinal arteriovenous lesions is to completely obliterate the shunt. In our institution, intraoperative digital subtraction angiography and intraarterial injection of contrast agent have been used to accurately identify the site of arteriovenous shunts. We describe the intraoperative digital subtraction angiography and intraarterial dye injection procedures and how they may improve surgical outcomes. ⋯ Intraoperative digital subtraction angiography and intraarterial dye injection are useful tools for management of spinal arteriovenous lesions.

To investigate facet tropism and its role in development of lumbar isthmic spondylolisthesis (IS) in young men. ⋯ Facet angle tropism is seen in a high proportion of patients with IS and seems to be a predisposing factor in the etiology of IS.
