Laser Ablation Therapy for Pediatric Patients with Intracranial Lesions in Eloquent Areas.
Laser interstitial thermal therapy (LITT) is an alternative, less-invasive, and, in some circumstances, effective treatment for patients with intracranial pathology including epilepsy and some tumors. For intracranial lesions in eloquent areas, resection by conventional craniotomy proves often to be a challenge, including in the care of pediatric patients. Herein, we reviewed our experience with magnetic resonance imaging (MRI)-guided LITT as treatment for pediatric patients with intracranial lesions in eloquent areas and evaluate neurologic function and clinical outcomes. ⋯ For intracranial lesions in the eloquent cortex, conventional craniotomy with surgical resection is a challenge for neurosurgeons, especially pediatric patients. MRI-guided LITT provides a less-invasive and potentially effective option for treatment in the management of pediatric epilepsy and tumors.

Pupillary light reflex examinations are intrinsic to any good neurological examination. Consistent evidence has shown that automated pupillometry assessments provide superior accuracy and interrater correlation compared with bedside eye examinations. Pupillary indexes such as the neurological pupil index (NPI) can also provide several hours of warning before the advent of herniation syndromes or third nerve palsy. ⋯ The NPI seems to reliably correlate with third nerve function and appears to possess predictive temporal properties that could allow practitioners to anticipate neurological injury and recovery. These findings could affect the fields of neurosciences, trauma, military medicine, critical care, and ophthalmology.

Myelomeningocele patients with shunt-dependent hydrocephalus often require multiple shunt revisions, eventually exhausting first-line distal diversion sites. Ventriculoatrial (VA) shunts are used less commonly than ventriculoperitoneal shunts, but knowledge of their use and complications is important to the neurosurgeon's armamentarium. VA shunts differ from ventriculoperitoneal and ventriculopleural shunts in that the ideal distal catheter target is an anatomically small area in comparison with the peritoneal and pleural cavities. ⋯ This is the fourth reported instance of successful distal revision of a migrated VA shunt catheter via transfemoral endovascular snaring. Knowledge of the opportunities afforded by this technique and collaboration with thoracic surgery colleagues is of benefit to all neurosurgeons.

Ewing's sarcoma family tumors (ESFTs) are the second most common malignancy in children and adolescents. The purpose of the present retrospective study was to evaluate the prognostic role of inflammatory biomarkers and preoperative D-dimer levels in patients with spinal ESFTs. ⋯ Our results have indicated that the preoperative D-dimer level is an effective prognostic factor with discriminatory ability for DFS and OS, superior to other indicators. Also, CAR was favorable prognostic factor for OS. Nomograms of DFS and OS can be recommended as practical models to evaluate the prognosis for patients with spinal ESFTs.

Spinal surgery is taught and practiced within 2 different surgical disciplines, neurological surgery and orthopedic surgery. We have provided a unified analysis of academic productivity measured using the h-index attributable to spine-focused faculty at U.S. residency programs. ⋯ We present a unified view of academic productivity as measured by the h-index among neurosurgical and orthopedic surgery spine faculty, with some noticeable differences. These results can be used for benchmark purposes to assess the relative productivity of its faculty and could be of interest to those pursuing academic opportunities in spine surgery.
