Comparative Study
Global Diversity and Academic Success of Foreign-Trained Academic Neurosurgeons in the United States.
To quantify the proportion of academic neurosurgeons practicing in the United States who acquired residency training outside of the United States and compare their training backgrounds and academic success with those who received their residency training in the United States. ⋯ A small group of U.S. academic neurosurgeons (6.3%) have acquired residency training outside of the United States, representing all major regions of the world. Their general demographic data and academic accomplishments are comparable to those of U.S.-trained neurosurgeons.

We aimed to elucidate the effects of arachnoid plasty (ARP) on chronic subdural hematoma (CSDH) occurrence following clipping surgery. ⋯ Patients who underwent ARPs developed fewer CSDHs following UIA clipping surgery. The factors that predicted the development of CSDH included male sex, SDFC volume on POD 8, and ARP. In addition, the ARP patients had lower SDFC volumes (<15 mL). These findings suggested that ARP reduced the incidence of CSDHs after surgical clippings in patients with unruptured aneurysms.

Case Reports
Intracranial Blood Flow Changes in Patients with High-grade Severe Carotid Artery Stenosis after Stenting.
We investigated whether the cerebral hemodynamic changes of pre- and poststenting in patients with severe carotid stenosis differ by stenosis grades. ⋯ The improvement of brain perfusion combined with the normalization of collateral flow through the circle of Willis after CAS was observed only in patients with HGSS.

Prognostic factors for the disease course of patients with spondylodiscitis have not been well studied. ⋯ Compared with MRI, CT imaging parameters have a higher prognostic value regarding the disease course. Patients infected with low-virulence bacteria and atypical MRI findings are at higher risk for poor clinical outcome and thus warrant closer monitoring.

Laser interstitial thermal therapy has become increasingly popular for targeting epileptic foci in a minimally invasive fashion. Despite its use in >1000 patients, the long-term effects of photothermal injury on brain physiology remain poorly understood. ⋯ Prolonged incompetence of the blood-brain barrier produced by thermal ablation may provide a path for delivery of macromolecules into perilesional tissue, which could be exploited for therapeutic benefit, but rarely it may result in autoimmune central nervous system inflammatory conditions.
