Stroke is a leading cause of mortality and disability worldwide. Research activity in Latin American countries might be the key to solving, or at least improving, the understanding of stroke-related issues in the region. Our aim was to describe and analyze the research output on stroke in Latin America. ⋯ Despite the continuous increase in research output from Latin American countries, more effort is needed to strengthen the research capacity by developing networks and collaborative research projects, ideally among the Latin American countries themselves.

Women constitute a minority (9.2%) of academic neurosurgeons. We previously found that women in academic medicine are disadvantaged in funding and career advancement opportunities. We hypothesized that women are also underrepresented at neurosurgical society conferences. ⋯ In 2014-2018, underrepresentation of women in national neurosurgical conferences either matched or exceeded the baseline gender disparity seen in academic neurosurgery. We discussed potential causes of and strategies to address these findings.

3D printed models have grown in popularity for resident training. Currently there is a paucity of simulators specifically designed for advanced cervical instrumentation. Our institution created a unique simulator for the instruction of freehand placement of C2 laminar screws using a specific 3-dimensional printing technique to replicate the corticocancellous interface. This study was designed to determine the efficacy of the simulator for teaching neurosurgical residents the freehand technique of C2 laminar screw placement. ⋯ By utilizing our novel 3D printing production method, we have created a unique simulator for the freehand placement of C2 laminar screws. To our knowledge, this is the first report of a study investigating the use of a 3-dimensional printed simulator specifically designed to teach the freehand placement of C2 laminar screws to neurosurgical trainees.

Optic pathway gliomas and glioblastomas remain a rare entity within the infant population. ⋯ The patient remained clinically and radiologically stable at 1 year. Optic pathway glioblastoma in this population is a previously undescribed entity that requires multidisciplinary input to guide ongoing therapy.

Large epileptogenic type IIIb dysplasia: a radiological and anatomopathological challenge.
Type IIIb dysplasia is a subtype of focal cortical dysplasia associated with a tumor, most frequently with gangliogliomas then with dysembryoplastic neuroepithelial tumors (DNETs). Their preoperative diagnosis often remains equivocal since specific features are missing. The functional results (i.e., seizure free) is good with 81%-87% of Engel Ia at 5-year follow-up. ⋯ We describe a rare condition of type IIIb dysplasia combining a focal cortical dysplasia with a DNET. Preoperative diagnosis of the lesion was of utmost difficultly, thereby rendering mandatory a thorough histopathological examination of resected specimen in the vast majority of cases. Increased recognition of the condition brings up the hypothesis of a genetic continuum or linkage between the 2 conditions. Functional results on seizure activity after ablative surgery are good and maximal safe resection should be the goal.
