RESUMO
The aim of the study was to evaluate the clinical applicability of the 2017 ILAE classification of seizures and epilepsies through the analysis of a sample of 100 outpatients with a diagnosis of epilepsy. All clinical charts were reviewed applying both the 1981/1989 and 2017 classifications of seizures and epilepsies, respectively. For most focal seizures, descriptors were required to include all the relevant clinical information. The reclassification of complex partial seizures into focal seizures with impaired awareness with a motor / non-motor onset allowed the inclusion of features of topographic value, although the chronological sequence of awareness impairment was lacking. The use of the term "focal to bilateral tonic-clonic" reduced the number of seizures classified as generalized tonic-clonic seizures (GTCS) by 19%. A subset of GTCS (35%) and absence seizures (12.5%) were reclassified as seizures of unknown onset. Most focal symptomatic epilepsies (92%) were reclassified as focal structural epilepsies, while 27% of idiopathic generalized and 7% of focal cryptogenic epilepsies merged into the category of "epilepsies of unknown type". Major strengths of the new classification are simplicity and the role of the category "unknown onset" to avoid forced categorization. A section assigned to uncertainty reinforces the need for further ancillary studies and periodic diagnostic re-evaluation.

Introducción: El ataque cerebrovascular (ACV) es una importante causa de mortalidad, discapacidad y demencia en el mundo y en nuestro país. Provoca un gran impacto económico ya sea por gastos directos o indirectos. Objetivos: Describir aspectos clínicos, factores de riesgo e indicadores que permiten un adecuado manejo del ACV en su tratamiento agudo. Material y Métodos: Se realizó un estudio descriptivo y prospectivo de los ACV ingresados en el Hospital de Clínicas, entre 2007 y 2012 aplicando un protocolo con escalas clínicas, etiopatogénicas y funcionales, con test estadísticos adecuados. Resultados: Se protocolizaron 784 pacientes: 75% infartos, 16% hemorragias y 9% AIT. La HTA fue el factor de riesgo más frecuente. Un tercio llegó a puerta antes de las 4,5 h. En infartos y AIT se disminuyeron los días de internación y se mejoró la funcionalidad a 6 meses. Conclusiones: La formación de equipos entrenados en el diagnóstico y tratamiento del ACV disminuyeron el tiempo de internación y mejoraron la funcionalidad de estos pacientes.
Introduction: The cerebrospinal fluid (CSF) fistula is defined as the abnormal leak of fluid from the skull to outside the body through an osteomeningeal gap, which allows the passage of organisms to the intra-cranial space, with the risk of infection, potentially life-threatening. Divided as traumatic and non-traumatic, the condition is relatively common, and poses great challenges to neurosurgeons. Objective: to present the first case of post-traumatic CSF fistula in Uruguay, assessed with cistern MRI with diagnostic purposes. Case report: the case described is that of a patient that received treatment at the University Hospital (Hospital de Clínicas). The case is used to illustrate the condition and review the latest controversial issues involved in the algorithms for the diagnosis and therapy of the condition. Discussion: the main controversial issues found included the following: when to start prophylactic antibiotic (ATB) therapy following diagnosis; imaging tests requested for diagnosis, and type of therapy prescribed. Conclusions: The review of literature leads us to conclude that a correct diagnosis requires the routine use of CT and MRI; if doubts persist, cistern MRI, endoscopy, or cistern CT are indicated. With regards the therapeutic algorithm, we conclude that therapy should be conservative, applying medical therapy for two to four weeks; surgery will be prescribed if the fistula persists after that. Antibiotic therapy is an option and not a recommendation.
