Cranial juvenile psammomatoid ossifying fibroma: case report.

Juvenile psammomatoid ossifying fibroma (JPOF) is a fibroosseous tumor that arises in the craniofacial bones in young people. This lesion usually originates in the jaw, orbit, and ethmoid complex but can also be associated with the skull base and calvaria. Diagnosis must be made based on observing typical radiological and histopathological features. Although JPOF is a rare pathological entity, neurosurgeons must consider this odontogenic lesion in the differential diagnosis of skull masses given the lesion's aggressive behavior and locally invasive growth. Treatment must be gross-total resection. In the following article, the authors present a case of cranial JPOF and discuss various aspects of this entity.

Delayed spontaneous pneumocephalus inventriculoperitoneal shunting: Two case reports andliterature review

El neumoencéfalo a tensión es una rara complicación después de la colocación de sistemas de derivación de líquido cefalorraquídeo. En la mayoría de casos la etiopatogenia está relacionada con un defecto de la base del cráneo. Presentamos 2 casos de neumoencéfalo tardío a tensión después de la colocación de derivación ventriculoperitoneal y revisamos la literatura, analizando los mecanismos de etiopatogenia, así como las posibles formas de prevención y tratamiento

Spontaneous pneumocephalus following cerebrospinal fluid shunt is a rare complication. In most cases, the air enters in the intracranial cavity via a skull base defect. We report 2 cases of delayed tension pneumocephalus, secondary to ventriculoperitoneal shunt, and review the etiopathogenesis, prevention and treatment of this condition

Delayed spontaneous pneumocephalus in ventriculoperitoneal shunting: two case reports and literature review.

Spontaneous pneumocephalus following cerebrospinal fluid shunt is a rare complication. In most cases, the air enters in the intracranial cavity via a skull base defect. We report 2 cases of delayed tension pneumocephalus, secondary to ventriculoperitoneal shunt, and review the etiopathogenesis, prevention and treatment of this condition.

[Primary prophylaxis of early seizures after surgery of cerebral supratentorial tumors: Group for the Study of Functional-Sterotactic Neurosurgery of The Spain Society of Neurosurgery recommendations]. / Control de las crisis epilépticas durante el postoperatorio inmediato de los tumores cerebrales supratentoriales: recomendaciones del Grupo de Neurocirugía Funcional y Estereotáctica de la Sociedad Española de Neurocirugía.

Our review of the literature is basically focused on the primary prophylaxis of early seizures after surgery of cerebral supratentorial tumors, with the aim of suggesting several recommendations in medical antiepileptic treatment to avoid this kind of seizures which occur immediately after surgery. In conclusion, it is recommended to provide criteria for prophylaxis of early seizures after surgery of cerebral supratentorial tumors. It́s recommended a one week treatment with antiepileptic drugs in patients who didnt have seizures jet, starting immediately after the surgical treatment. If seizures appear during progress of the disease, a large period treatment will be needed. Preferred antiepileptic treatment is intravenous and with a low interactions profile. Levetiracetam, followed by valproic acid seem to be most appropriated drugs due to their properties and protective effects, particularly for our patients requirements. These recommendations are considered a general proposal to effective clinical management of early seizures after surgery, not taking into account the single circumstances of our patients. Always, clinical features of the patients could modify even significantly these guides in the benefit of each patient.

Con la finalidad de proponer una serie de recomendaciones del tratamiento médico antiepiléptico, en el perioperatorio de los tumores cerebrales supratentoriales, se realiza una revisión de la literatura enfocada sobre todo a la profilaxis primaria de las crisis epilépticas precoces acaecidas en el postoperatorio inmediato. Se concluye que es recomendable pautar profilaxis primaria antiepiléptica poscirugía durante una semana en los pacientes con tumor cerebral supratentorial que no han presentado crisis epilépticas. Si las crisis aparecen durante la evolución de la enfermedad, es necesario pautar un tratamiento a largo plazo. Dadas las características de estos pacientes, se recomienda usar un fármaco antiepiléptico con presentación por vía intravenosa y un perfil bajo de interacciones. El levetiracetam, seguido del valproato, parecen ser los más adecuados. Dichas recomendaciones deben considerarse como una guía general de manejo, pudiendo ser modificadas, incluso de manera significativa, por las circunstancias propias de cada caso clínico (AU)
