Hinge Craniotomy for Posterior Cranial Vault Expansion: Using the Keel to the Surgeon's Advantage.

Cranial vault reconstructions are a common craniofacial procedure utilized to treat chronically elevated intracranial pressure and its sequelae for children with craniosynostosis. These surgeries often involve split-thickness autologous grafts to facilitate intracranial volume expansion. The hinge craniotomy was developed by neurosurgeons in the early 2000s as an alternative to the hemicraniectomy to allow for greater space and simplified re-securing of the bone flap.

Placement of Endovascular Stent for Reperfusion of Cerebral Infarct After Pediatric Traumatic Internal Carotid Artery Dissection.

Background: Traumatic intracranial ICA dissections are not commonly seen in children. Dissection resulting in perfusion deficit warrants intervention. Here we encountered a patient who experienced traumatic ICA dissection, treated by endovascular stenting.

Mechanistic insights gained from cell and molecular analysis of the neuroprotective potential of bioactive natural compounds in an immortalized hippocampal cell line.

Evaluating novel compounds for neuroprotective effects in animal models of traumatic brain injury (TBI) is a protracted, labor-intensive and costly effort. However, the present lack of effective treatment options for TBI, despite decades of research, shows the critical need for alternative methods for screening new drug candidates with neuroprotective properties. Because natural products have been a leading source of new therapeutic agents for human diseases, we used an in vitro model of stretch injury to rapidly assess pro-survival effects of three bioactive compounds, two isolated from natural products (clovanemagnolol [CM], vinaxanthone [VX]) and the third, a dietary compound (pterostilbene [PT]) found in blueberries.

Virtual Reality in the Neurosciences: Current Practice and Future Directions.

Virtual reality has made numerous advancements in recent years and is used with increasing frequency for education, diversion, and distraction. Beginning several years ago as a device that produced an image with only a few pixels, virtual reality is now able to generate detailed, three-dimensional, and interactive images. Furthermore, these images can be used to provide quantitative data when acting as a simulator or a rehabilitation device.

Successful embolization of an upper cervical spinal dural fistula despite anterior spinal artery anastomosis.

A female in her 40s presented with classic symptoms of subarachnoid hemorrhage and limited mobility of the bilateral upper extremities. Imaging demonstrated a minor amount of subarachnoid blood, and a follow-up computed tomography angiogram revealed a spinal dural arteriovenous fistula (SDAVF) located at C2-3. The C2-3 radicular artery proximal to the fistula feeder anastomosed with the anterior spinal artery, challenging the safety of embolization.

A Systematic Review of Ion Radiotherapy in Maintaining Local Control Regarding Atypical and Anaplastic Meningiomas.

Objective: Atypical and anaplastic meningiomas, unlike their benign counterparts, are highly aggressive, locally destructive, and likely to recur after treatment. These diseases are difficult to definitively treat with traditional radiotherapy without injuring adjacent brain parenchyma. The physical properties of ion radiotherapy allows for treatment plans that avoid damaging critical neural structures.

Effect of an additional neurosurgical resident on procedure length, operating room time, estimated blood loss, and post-operative length-of-stay.

Neurosurgical residency training is costly, with expenses largely borne by the academic institutions that train residents. One expense is increased operative duration, which leads to poorer patient outcomes. Although other studies have assessed the effect of one resident assisting, none have investigated two residents; thus, we sought to investigate if two residents versus one scrubbed-in impacted operative time, estimated blood loss (EBL), and length-of-stay (LOS).

Cefazolin versus vancomycin for neurosurgical operative prophylaxis - A single institution retrospective cohort study.

Objectives: Cefazolin and vancomycin are common choices for neurosurgical antimicrobial prophylaxis. Cefazolin is typically first-line due to its lower toxicity profile and specificity for gram-positives such as skin commensals, while vancomycin is often reserved for patients with cephalosporin or penicillin allergies. However, one randomized clinical trial demonstrated superiority of vancomycin for cerebrospinal fluid (CSF) shunt insertions at a hospital with a high prevalence of methicillin-resistance Staphylococcus aureus (MRSA).

Genetic variability among group A and group B respiratory syncytial viruses in a children's hospital.

Respiratory syncytial (RS) viruses isolated over three epidemic periods in a children's hospital in the United States were analyzed. The viruses (n = 174) were characterized as to major antigenic group (group A or B) by a PCR-based assay. Group A RS viruses were dominant the first 2 years, followed by a year with group B dominance (ratios of group A to group B viruses for epidemic periods, 56/4 for 1993-1994, 42/3 for 1994-1995, and 19/50 for 1995-1996).

The referral process: a study of one method for improving communication between rural practitioners and consultants.

Communication between referring physicians and consultants, essential for successful completion of the consultative-referral process, was inadequate in a rural clinic. This finding prompted the authors to conduct a randomized prospective trial of a referral form and return mailer in three rural primary care clinics associated with a university medical center. The use of a return mailer increased the percentage of consultant feedback from 39 percent to 60 percent, a highly significant increase.
