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.
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.
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.
“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.
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.
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
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.
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.
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.
