World Health Organization Recommends Naloxone to Prevent 20,000 Overdose Deaths in U.S.

World Health Organization Recommends Naloxone to Prevent 20,000 Overdose Deaths in U.S.

Scientific American: Mind and Brain

More than 20,000 deaths might be prevented every year in the United States alone if naloxone, used to counter drug overdoses, was more widely available, the World Health Organization said on Tuesday.

New Internet Neurosurgery TV Channel Opening: www.neurosurgical.tv

Greetings, 

John Bennett MD  of InternetMedicine.com, and Julio Pereiras MD of Neurosurgery Blog weneuro.com , Neurosurgeon, and author, are starting a Neurosurgical Internet TV Channel, that we hope brings the worldwide community together, LIVE, on the computer.

Feel free to request to present any thing that you thing Neurosurgeons will be interested in.

We know all you guys are busy, and don't expect you to attend every week, for an hours, but maybe you can drop

by now and then, or give a presentation.

The Google Hangout tech is here: lets leverage it for communication, networking and education!

best

Magnetic Resonance Imaging Measures of Posterior Cranial Fossa Morphology and Cerebrospinal Fluid Physiology in Chiari Malformation Type I

Magnetic Resonance Imaging Measures of Posterior Cranial Fossa Morphology and Cerebrospinal Fluid Physiology in Chiari Malformation Type I

Neurosurgery - Current Issue

BACKGROUND: It has been well documented that, along with tonsillar herniation, Chiari Malformation Type I (CMI) is associated with smaller posterior cranial fossa (PCF) and altered cerebrospinal fluid (CSF) flow and tissue motion in the craniocervical junction. OBJECTIVE: This study assesses the relationship between PCF volumetry and CSF and tissue dynamics toward a combined imaging-based morphological-physiological characterization of CMI. Multivariate analysis is used to identify the subset of parameters that best discriminates CMI from a healthy cohort. METHODS: Eleven length and volumetric measures of PCF, including crowdedness and 4th ventricle volume, 4 measures of CSF and cord motion in the craniocervical junction, and 5 global intracranial measures, including intracranial compliance and pressure, were measured by magnetic resonance imaging (MRI) in 36 symptomatic CMI subjects (28 female, 37 ± 11 years) and 37 control subjects (24 female, 36 ± 12 years). The CMI group was further divided based on symptomatology into "typical" and "atypical" subgroups. RESULTS: Ten of the 20 morphologic and physiologic measures were significantly different between the CMI and the control cohorts. These parameters also had less variability and stronger significance in the typical CMI compared with the atypical. The measures with the most significance were clival and supraocciput lengths, PCF crowdedness, normalized PCF volume, 4th ventricle volume, maximal cord displacement (P < .001), and MR measure of intracranial pressure (P = .007). Multivariate testing identified cord displacement, PCF crowdedness, and normalized PCF as the strongest discriminator subset between CMI and controls. MR measure of intracranial pressure was higher in the typical CMI cohort compared with the atypical. CONCLUSION: The identified 10 complementing morphological and physiological measures provide a more complete and symptomatology-relevant characterization of CMI than tonsillar herniation alone.
