Presencia de gas en estructuras vasculares venosas encefálicas como hallazgo incidental en tomografía computada de encéfalo en ausencia de trauma / Presence of gas in encephalic vascular venous structures as an incidental finding in brain computed tomography in the absence of trauma

The presence of gas in the cerebral vascular venous structures is a finding that we infrequently see in our specialty. On many occasions we cannot pinpoint the cause, alarming the clinician, suggesting unnecessary exams, hospitalizations and controls. We performed a review of the literature and a retrospective study with the cases that we have reported in computed tomography of the brain in our radiology service, from January 2010 to July 2017.

La epilepsia refractaria del adulto y los antiepilépticos nóveles: el rol de la gabapentina / Refractary epilepsy in adults and new antiepileptic drugs: role of gabapentin

The features of refractory epilepsies and the role of functional surgery and new antiepileptic drugs is reviewed. Among the latter, gabapentin, a drug with peculiar pharmacokinetic properties, is highlighted as a therapeutic alternative in refractory epilepsies and eventually for epileptic patients without previous treatment. A new type of relationship between the pharmaceutical industry and physicians, that privileges clinical research is discussed
