The University at Buffalo's neuroendovascular fellowship is one of the longest running fellowship programs in North America. The burgeoning neurointerventional workforce and the rapid growth in the neurointerventional space on the heels of groundbreaking clinical trials prompted us to assess the fellowship's academic impact and its graduates' perceptions and productivity. An anonymized web-based survey was sent to all former neuroendovascular fellows with specific questions pertaining to current practice, research and funding, and perceptions about the fellowship's impact on their skills, competitiveness, and compensation...

BACKGROUND: Pneumocephalus, illustrated by air in the cranial vault is relatively infrequent and generally associated with neurosurgery, trauma, meningitis and barotrauma. However cases of spontaneous non-traumatic pneumocephalus remain rare. While the relationship between continuous positive airway pressure (CPAP) and atraumatic pneumocephalus has been previously reported, to our knowledge the rare presentation associated with sinus wall osteomyelitis has never been described. We summarize here the case of a 67-year-old woman's acute presentation of Streptococcus salvarius infection after a sudden drop in her consciousness...

BACKGROUND: Various techniques have been employed for the early detection of perioperative cerebral ischaemia and hypoxia. Cerebral near-infrared spectroscopy (NIRS) is increasingly used in this clinical scenario to monitor brain oxygenation. However, it is unknown whether perioperative cerebral NIRS monitoring and the subsequent treatment strategies are of benefit to patients. OBJECTIVES: To assess the effects of perioperative cerebral NIRS monitoring and corresponding treatment strategies in adults and children, compared with blinded or no cerebral oxygenation monitoring, or cerebral oxygenation monitoring based on non-NIRS technologies, on the detection of cerebral oxygen desaturation events (CDEs), neurological outcomes, non-neurological outcomes and socioeconomic impact (including cost of hospitalization and length of hospital stay)...

BACKGROUND: Sitting position is preferred during posterior fossa surgeries as it provides better anatomical orientation and a clear surgical field. However, its use has been declining due to its propensity to cause life-threatening complications. This study was carried out to analyze the perioperative complications and postoperative course of children who underwent neurosurgery in sitting position. MATERIALS AND METHODS: Medical records of 97 children (<18 years) who underwent neurosurgery in sitting position over a period of 12 years, were retrospectively analyzed...

BACKGROUND: Ependymomas are rare tumors of the central nervous system. The local tumor distribution in the central nervous system is highly age-dependent as among adults ependymomas occur mostly in the spinal cord, whereas among children intracranial manifestations are more common. To date, there are no prospective studies about treatment strategies for ependymomas. In most cases complete tumor resection is recommended. The role of radiation therapy in low-grade ependymomas remains unclear...

QUESTION 1: What surgical approaches for vestibular schwannomas (VS) are best for complete resection and facial nerve (FN) preservation when serviceable hearing is present? RECOMMENDATION: There is insufficient evidence to support the superiority of either the middle fossa (MF) or the retrosigmoid (RS) approach for complete VS resection and FN preservation when serviceable hearing is present. QUESTION 2: Which surgical approach (RS or translabyrinthine [TL]) for VS is best for complete resection and FN preservation when serviceable hearing is not present? RECOMMENDATION: There is insufficient evidence to support the superiority of either the RS or the TL approach for complete VS resection and FN preservation when serviceable hearing is not present...

Leptomeningeal metastasis (LM) results from dissemination of cancer cells to both the leptomeninges (pia and arachnoid) and cerebrospinal fluid (CSF) compartment. Breast cancer, lung cancer, and melanoma are the most common solid tumors that cause LM. Recent approval of more active anticancer therapies has resulted in improvement in survival that is partly responsible for an increased incidence of LM. Neurologic deficits, once manifest, are mostly irreversible, and often have a significant impact on patient quality of life...

The field of non-invasive stimulation of the cerebellum is quickly expanding. The anatomical structure of the cerebellum with a high density of neurons in the superficial layer, its electrical properties, and its participation in numerous closed-loop circuits involved in motor, cognitive, and affective operations both in children and in adults make of the cerebellum a target with very high potential for neuromodulation of both cerebellar and extra-cerebellar disorders, in neurology, psychiatry, and neurosurgery...

Computed tomography (CT) scan of the brain transitioned clinical neurology from the educated-guess world to the real computer-age world. One of the first CT scans-published by the British neuroradiologist James Ambrose-showed an intracranial hemorrhage and also suggested the use of iodine to demonstrate abnormal blood-brain barrier. In the USA, CT scans were rapidly commercialized and first placed at Mayo Clinic and Massachusetts General Hospital in the summer of 1973. CT scanning of the brain has revolutionized diagnostic acute neurology and neurosurgery and was the overture to an even larger revolution-magnetic resonance imaging...

Background Many specialty societies have found that neuroimaging in headache is a low-value intervention for benign presentations. This study describes factors that influence Emergency Room (ER) physicians' adherence to Choosing Wisely (CW) recommendations for low-risk headache patients presenting to Calgary's Emergency Departments (EDs). Emergency medicine has yet to address imaging in headache as a CW topic; however, this study may inform that decision. Methods Data were retrospectively collected for all patients presenting to Calgary EDs with headaches from April 1, 2014 to March 31, 2016...

Corey T Walker, M Yashar S Kalani, Mark E Oppenlander, Jakub Godzik, Nikolay L Martirosyan, Robert J Standerfer, Nicholas Theodore
OBJECTIVE The authors report a novel paradigm for resection of the disc or dural complex to treat giant calcified transdural herniated thoracic discs, and they describe a technique for the repair of dural defects. These herniated thoracic discs are uncommon, complicated lesions that often require a multidisciplinary team for effective treatment. The intradural component must be removed to effectively decompress the spinal cord. The opening of the friable dura mater, which frequently adheres to the extradural component of the disc, can result in large defects and difficult-to-manage CSF leaks...

The 2016 scientific meeting of the American Association of Neurological Surgeons (AANS) focused on the theme "A World of Innovation." In his presidential address, 2016 AANS President Frederick Boop compared the historical development of the specialty of neurological surgery with that of the development of global communications. In the early years, general surgeons training in the United States would spend post-residency time abroad learning from surgical masters in Europe and other places. Since Harvey Cushing's day, neurosurgeons from around the world continue to travel abroad, with many now coming to America for training at centers of excellence...

BACKGROUND: In previous studies of pneumococcal meningitis in adults within general hospitals or national cohorts, the most common predisposing conditions are otitis media, sinusitis, pneumonia, immunosuppression, alcoholism, and diabetes. The epidemiology of pneumococcal meningitis is changing due to the use of vaccines in childhood, and antibiotic resistance has increased. METHODS: We retrospectively reviewed the cases of patients with diagnosis of pneumococcal meningitis proved by an inflammatory CSF with a positive culture, treated during a period of 14 years at an adult neurosurgical neurological reference center...
