Precise statistical analysis showed strong correlation of pial invasion ([chi square]=14.43; p=3.84), dural invasion ([chi square]=13.48; p=3.84) and bone infiltration ([chi square]=14.24; p=3.84) with tumor margins.
In all pediatric and young adult patients, with clinical presentation of seizures, headaches, developmental delay or mental retardation and pial angiomatosis and cortical calcifications confirmed by magnetic resonance imaging, type III Sturge-Weber syndrome should be considered.

Cortical thickness was measured as the difference between the position of equivalent vertices in the pial and GM/WM surfaces, by utilizing both intensity and continuity information from the entire 3-dimensional MR volume in the segmentation and deformation procedures.
The white surface and the pial surface are generated for each hemisphere using encoding the shape of the corpus callosum and pons in the Talairach space and following the intensity gradients from the white matter.
Sin mediar aviso o requerimiento previo, inspectores de la Direccion General de Habilitaciones y Permisos del GCBA, cerraron las puertas del Club El Pial. Esto desperto una gran agitacion en los organizadores de milongas dado que, desde la epoca del lamentable suceso de Cromanon, que dio origen a la reglamentacion que creo la Categoria--Salon Milonga--, pareceria que para muchos no quedo lo suficientemente clara la misma.
In eloquent areas the surgeon uses a subpial dissection technique, where the pial bank is preserved against blood vessels and nerves, while the grey matter is dissected out and away from the white matter tracts, often using an ultrasonic aspirating device on very low suction and fractionation settings.
Then, focal ischemia was induced by stereotaxic microinjection of 1 [micro]L (40 pmol) endothelin-1 (ET-1), a potent vasoconstrictor, into the left motor cortex (2.3 mm lateral and 1.2 mm posterior from bregma and 0.4 mm below the pial surface).
More specifically, the ophthalmic division (V1) of the trigeminal nerve innervates dural and pial blood vessel nociceptors that, when activated, cause a release of vasoactive neuropeptides such as substance P, calcitonin gene-related peptide, and neurokinin A which in turn cause increased cerebral blood flow, release of proinflammatory factors, and a reaction called neurogenic inflammation [27].
