Ventriculo-peritoneal shunt procedures can improve idiopathic normal pressure hydrocephalus (iNPH) symptoms. However, there are no automated methods that quantify the presurgery and postsurgery changes in the ventricular volume for computed tomography scans. Hence, the main goal of this research was to quantify longitudinal changes in the ventricular volume and its correlation with clinical improvement in iNPH symptoms. Furthermore, our objective was to develop an end-to-end graphical interface where surgeons can directly drag-drop a brain scan for quantified analysis. ⋯ Proposed metric quantifies changes in ventricular volume before and after shunt surgery for patients with iNPH, serving as an automated and effective radiographic marker for a functioning shunt in a patient with iNPH.

Education and Training in Global Neurosurgery: The Quest for Diversity and Equitable Collaborations.
Education and training are essential components of global neurosurgery because they provide a sustainable solution to address the workforce deficits in the neurosurgical burden of disease. Neurosurgery training programs and opportunities exist in most areas of the world, but some countries still lack formal mechanisms to train future generations. In this special article, we review the neurosurgical workforce deficit, characterize factors influencing the absence or inadequacy of neurosurgical training, and identify strategies that could facilitate global efforts in building a stronger workforce. ⋯ In addition, we evaluate the "brain drain" issue in the larger context of the healthcare workforce and propose solutions to mitigate this phenomenon in neurosurgical practice. Future generations of neurosurgical trainees depend on our efforts to intensify and expand education and training in this new virtual era. As we look to the future, we must prioritize education to strengthen the future neurosurgeons who will lead and shape the frontiers of our field.

Rates and Predictors of Pain Reduction With Intracranial Stimulation for Intractable Pain Disorders.
Intracranial modulation paradigms, namely deep brain stimulation (DBS) and motor cortex stimulation (MCS), have been used to treat intractable pain disorders. However, treatment efficacy remains heterogeneous, and factors associated with pain reduction are not completely understood. ⋯ Both DBS and MCS have similar efficacy and complication rates in the treatment of intractable pain. Patients with central pain disorders tended to have lower trial success and higher rates of device cessation. Additional prognostic factors include anterior cingulate cortex targeting and postherpetic neuralgia diagnosis. These findings underscore intracranial neurostimulation as an important modality for treatment of intractable pain disorders.
