Neurosurgical management of brain tumors has entered a paradigm of supramarginal resections that demands thorough understanding of peritumoral functional effects. Historically, the effects of tumors have been believed to be local, and long-range effects have not been considered. ⋯ This work provides evidence supporting the theory that focal brain tumors produce long-range gradients in function. Consequently, the effects of focal lesions need to be interpreted in terms of the global changes on functional complexity and network architecture rather than purely in terms of functional localization. Determining whether peritumoral changes represent potential plasticity may facilitate extended resection of tumors without functional cost.

Aging of the population has prompted an escalation of service utilization and costs in many jurisdictions including North America. However, relatively little is known on the economic impact of old age on the management of acute spine trauma (AST). ⋯ Given the escalating demand for surgical and nonsurgical spine treatment in the age of aging population, the timely results of this study underline key aspects of the economic impact of the spine care of the elderly. Further investigations are needed to fulfill significant knowledge gaps on the economics of caring for elderly with AST.

One-third of patients with aneurysmal subarachnoid hemorrhage (aSAH) have multiple intracranial aneurysms (MIA). ⋯ aSAH patients with MIA have a higher short-term morbidity than patients with SIA. This excess morbidity does not worsen the functional outcome or lower overall survival.

In nonsurgical adult moyamoya disease (MMD) patients with ischemic onset and stable hemodynamics, the cerebral hemodynamic and cognitive course remains unclear. ⋯ Among adult patients receiving medication alone for symptomatically ischemic MMD without cerebral misery perfusion, the incidence of recurrent ischemic events was 3% per 2 yr. In patients without recurrent ischemic events, cerebral hemodynamics and cognitive function had not deteriorated by 2 yr after the last event.

Commentary: The Tulane University-Ochsner Clinic Foundation Neurosurgery Program: 75 Years of History, Including the Program's Rebirth After Katrina.
Neurosurgery training in New Orleans began when Dr Dean Echols became the head of Neurosurgery for the Ochnser Clinic and Charity Hospital in 1944. The oldest in Louisiana, the Tulane-Ochsner program has trained 63 board-certified neurosurgeons since its founding, including 5 chairmen. The program has a colorful history linked to New Orleans. Its residents have enjoyed training at Charity Hospital, Tulane Hospital and Clinics, Veterans Affairs Medical Center, and the Ochsner Clinic Foundation.
