Higroma subdural secundario a la rotura de quiste aracnoideo intracraneal: descripción de 2casos y revisión de la literatura / Subdural hygroma secondary to rupture of an intracranial arachnoid cyst: description of 2cases and review of the literature

La aparición de un higroma subdural tras la rotura de la pared de un quiste aracnoideo es extremadamente infrecuente. Existen muy pocos casos descritos en la literatura. La mayoría de los casos se deben a una causa traumática. Su abordaje terapéutico, en aquellos casos sintomáticos, es controvertido, con una tendencia en la actualidad hacia el manejo conservador de forma inicial. En aquellos casos que precisen tratamiento quirúrgico existen múltiples opciones terapéuticas: se recomiendan las técnicas de fenestración como primera opción. Describimos 2casos tratados en nuestro centro, junto con una revisión de la literatura

Angiolipoma epidural lumbar / Lumbar spinal angiolipoma

Los angiolipomas espinales son tumores de carácter benigno poco frecuentes que habitualmente se localizan en el espacio epidural de la columna torácica y que representan del 0,14 al 1,2% de todos los tumores espinales. Los angiolipomas lumbares son aún más infrecuentes, representando solo el 9,6% de todos los angiolipomas extradurales. Presentamos el caso de una mujer que refería dolor lumbar de varios meses de evolución, que se intensificó en los 3 últimos días, sin antecedentes de traumatismo ni esfuerzo físico y que no presentaba déficit neurológico. En la resonancia magnética se apreciaba una masa extradural a nivel lumbar L1-L2 y de localización posterior que producía una disminución del diámetro anteroposterior del canal medular. La paciente después de la cirugía mejoró su sintomatología. En la mayoría de los casos es posible realizar una extirpación total de la lesión, siendo el pronóstico excelente incluso si la lesión es infiltrante. Por ello se aconseja no adoptar una actitud quirúrgica excesivamente agresiva de cara a conseguir una resección completa

Spinal angiolipomas are fairly infrequent benign tumours that are usually located in the epidural space of the thoracic column and represent 0.14% to 1.3% of all spinal tumours. Lumbar angiolipomas are extremely rare, representing only 9.6% of all spinal extradural angiolipomas. We report the case of a woman who complained of a lumbar pain of several months duration with no neurological focality and that had intensified in the last three days without her having had any injury or made a physical effort. The MR revealed an extradural mass L1-L2, on the posterior face of the medulla, decreasing the anteroposterior diameter of the canal. The patient symptoms improved after surgery. Total extirpation of the lesion is possible in most cases, and the prognosis is excellent even if the lesion is infiltrative. For this reason, excessively aggressive surgery is not necessary to obtain complete resection

Liponeurocitoma del ventrículo lateral izquierdo. Revisión del primer caso descrito en España y análisis de la bibliografía / Liponeurocytoma in the left lateral ventricle. Presentation of the first case reported in Spain and literature review

El liponeurocitoma supratentorial es un tumor excepcional, de predominio en varones jóvenes. Su localización habitual son los ventrículos laterales, siendo excepcional la afectación del iii ventrículo. Se define como un tumor neuronoglial, de bajo grado, con áreas de lipomatosis asociada. La manifestación clínica más frecuente es la derivada de la aparición de hidrocefalia e hipertensión intracraneal secundaria. Presentamos el primer caso descrito en España de esta estirpe tumoral y uno de los pocos presentados, hasta la fecha, en las bases bibliográficas. Se describe el caso de un varón de 33 años de edad, afectado de clínica sensitiva crural y cefalea de reciente inicio. El estudio radiológico mostró la presencia de una gran tumoración supratentorial, intraventricular, multiquística, heterogénea, con áreas de lipomatosis asociada. El paciente fue intervenido, consiguiéndose la exéresis tumoral completa. El diagnóstico definitivo fue de liponeurocitoma supratentorial. La presencia de una tumoración intraventricular supratentorial, con áreas de degeneración grasa, debe obligar a considerar, dentro del diagnóstico diferencial, este tipo de tumor. La resección tumoral completa se considera el tratamiento de elección

Supratentorial liponeurocytoma is a rare tumor, predominatly appearing in young males. It most commonly affects the lateral ventricles, with involvement of the third ventricle being exceptional. It is defined as a low-grade neuroglial tumor, with areas of associated lipomatosis. The most common clinical manifestation is that resulting from the presence of secondary intracranial hypertension and hydrocephalus. We present the first case reported in Spain of this tumor type and one of the few appearing in the literature so far. We report the case of a 33-year-old male patient, suffering from crural sensitive sympoms and recent onset headache. The radiographic study revealed the presence of a large supratentorial tumor; intraventricular, multicystic, heterogeneous and with areas of associated lipomatosis. The patient underwent surgery and complete tumor resection was achieved. The definitive diagnosis was of supratentorial liponeurocytoma. The presence of a supratentorial intraventricular tumor with areas of fatty degeneration should lead us to consider this type of tumor in the differential diagnosis. Complete tumor resection is considered to be the treatment of choice

[Smoking among a cohort of Spanish university graduates. The SUN Project]. / Consumo de tabaco en titulados universitarios. El Proyecto SUN (Seguimiento Universidad de Navarra).

OBJECTIVE: The objective of this study was to assess the association between employment, educational level, marital status, and smoking in a large cohort of Spanish university graduates (3- and 5-year degrees), with a predominance of health professionals. METHODS: A cross-sectional analysis of the baseline data of the first 7,508 participants in the follow-up study of the University of Navarre (SUN Project) was performed. The subjects were classified according to their smoking status. Independent variables were: employment, marital status, highest educational level attained, number of children, alcohol consumption (g/day), body mass index, and age. In the multivariate analysis, 3 non-conditional logistic regression models were built using the following outcomes: a) smokers vs never-smokers plus ex-smokers; b) smokers vs never-smokers; c) smokers of 15 or more cigarettes a day vs smokers of less than 15 cigarettes a day plus never-smokers and ex-smokers. RESULTS: Among men, no association was found between employment and smoking status in any of the comparisons. In contrast, among women, being a nurse was associated with a higher prevalence of smoking. The prevalence of current smokers among nurses was 48.5%. Female students were also more likely to smoke and had a higher risk of being heavy smokers (OR = 1.81; 95% CI, 1.28-2.57). A lower prevalence of smoking was found among participants of both sexes who had completed a doctorate. CONCLUSIONS: Among a large Spanish collective with higher education, the prevalence of smoking was higher in women with a shorter college degree. The prevalence of smoking among nurses was higher than the average among women graduates, which is a cause for concern.
