Researchers at Brown University examined three magnetically programmable shunt valves to see if the magnetic field emissions of headphones can cause unintentional changes in shunt valve settings. Based on their findings, the researchers state that it is highly unlikely that commercially available headphones will interfere with programmable shunt valve settings.
Researchers from Vienna examined elderly patients and adult patients receiving antiplatelet therapy who had presented with mild head injury to see if S100B protein levels could help identify whether intracranial bleeding was present. The researchers found that patients with serum S100B levels < 0.105 µg/L were very unlikely to have intracranial hemorrhage.
Researchers investigated mannitol use before and during transportation of patients with intracranial emergencies from peripheral hospitals to tertiary facilities that house neurosurgery departments. The authors found a 22% dosing error rate, with slightly more patients receiving a dose smaller, rather than larger, than the dose range recommended by the Brain Trauma Foundation.
Researchers examined neuroimaging studies obtained in children and adolescents with sports-related concussions and found that the images appeared normal in 78% of cases. Although usually nondiagnostic, occasionally such studies can be useful in guiding decisions about return to play.
Researchers from the Canada North Concussion Network in Manitoba investigated the frequency of vestibulo-ocular dysfunction in children and adolescents with sports-related concussion and found that its presence was predictive of a prolonged recovery.
A surgical skills laboratory and corresponding dissection curricula were established in the Department of Neurosurgery at the Cleveland Clinic in the 2011–2012 academic year. The authors describe how this came about and what it has meant for neurosurgical resident training and assessment of residents’ surgical skills.
The American Association of Neurological Surgeons, the Congress of Neurological Surgeons, and the Joint AANS/CNS Cerebrovascular Section strongly endorse interventional thrombectomy in the treatment of acute ischemic stroke based on findings of the MR CLEAN study.
43% of surveyed female meningioma survivors aged 25–44 yrs stated they were warned that pregnancy was a risk factor for meningioma recurrence. Nevertheless, these women were more likely to want a baby (70% vs 54%) and intend to have a baby (27% vs 12%) than same-age women in the general population.
The use of flow-diverting stents to treat intracranial aneurysms appears safe and highly successful. Ischemic complications occur in brain territories supplied by the parent artery in which the stent is placed and in brain regions fed by small arterial branches whose ostia are covered by the stent. Most of these complications are asymptomatic.
Researchers conducted a prospective randomized controlled clinical trial to compare a laparoscopic procedure with a mini-laparotomy for insertion of a peritoneal catheter during ventriculoperitoneal shunt surgery. Although overall shunt failure rates did not differ substantially between patients in the two surgery groups, the authors identified a significant reduction in the rate of distal (abdominal) shunt failure in patients in whom laparoscopy was used. Using Laparoscopy For Ventriculoperitoneal Shunt Placement
A formal protocol for delivering emergency treatment to patients with subarachnoid hemorrhage (SAH) from ruptured aneurysms within the first few hours after bleeding occurs. Offered day and night, the protocol reduces the incidence of repeated hemorrhage during the hospital stay and improves clinical outcomes in patients with aneurysmal SAH.
“Pediatric hydrocephalus: systematic literature review and evidence-based guidelines,” a supplement to the Journal of Neurosurgery: Pediatrics, offers a thorough evaluation of the current treatments for pediatric hydrocephalus as well as up-to-date evidence-based recommendations for their use.
The Journal of Neurosurgery Publishing Group and its parent organization, the American Association of Neurological Surgeons, are pleased to announce a new look for the JNSPG journals: Journal of Neurosurgery; Journal of Neurosurgery: Spine; Journal of Neurosurgery: Pediatrics; and Neurosurgical Focus
Researchers investigating gene expression in normal vestibular nerves and vestibular schwannomas (VSs) found 2 important findings: 1) there is negligible difference between VSs that sporadically occur and those commonly associated with neurofibromatosis Type 2 (NF2), a genetic disorder; and 2) the overexpressed PI3K/AKT/mTOR signaling pathway in these tumors may be an excellent therapeutic target.
This supplement to the Journal of Neurosurgery covers the current knowledge of anticoagulant-associated intracerebral hemorrhage (AAICH) and methods in use for management of the condition. CME credits are available.
A spinal mass was found in a woman with complete spinal cord injury 8 years after she had undergone implantation of olfactory mucosal cells to hopefully regain sensory and motor function. Authors caution that physicians should be vigilant in follow-up of patients who undergo stem cell interventions.
