Study of the population of immature neurons in the adult piriform cortex layer II
2019
Physiological studies indicate that the piriform or primary olfactory cortex of adult mammals exhibits a high degree of synaptic plasticity. Interestingly, a subpopulation of cells in the layer II of the adult piriform cortex expresses neurodevelopmental markers, such as the polysialylated form of neural cell adhesion molecule (PSA-NCAM) or doublecortin (DCX). This study analyzes the nature, origin, and potential function of these poorly understood cells in mice. As previously described in rats, most of the PSANCAM expressing cells in layer II could be morphologically classified as tangled cells and only a small proportion of larger cells could be considered semilunar-pyramidal transitional…
Nuevos recursos sanitarios en época de crisis: el papel del trabajador social en la Unidad de Neurorehabilitación Infantil del Hospital de Manises
2013
En los últimos años se ha detectado un aumento en los niños diagnosticados con Trastornos Generalizados del Desarrollo (TGD) y Daño Cerebral (DC). Al mismo tiempo la formación e información por parte de los profesionales que intervienen con estos niños también es mayor por lo que el Departamento de Salud de Manises creó en mayo del 2012 la primera Unidad de Neurorrehabilitación Infantil integrada en un hospital público valenciano especializada en estos casos. La Unidad está atendida por un equipo de profesionales especializados en TGD y DC, tanto en el diagnóstico como en la intervención y con una filosofía de trabajo interdisciplinar. Este equipo cuenta con la figura del trabajador social …
Implicación de los receptores TLR4 en el daño cerebral causado por el consumo de alcohol
2012
El abuso de alcohol puede causar daño cerebral y en ciertos casos cursa con neurodegeneración, aunque los mecanismos moleculares de estos efectos se desconocen. El Sistema Nervioso Central (SNC) ha sido considerado, hasta muy recientemente, como un sistema inmunológicamente privilegiado (Galea et al., 2007). Sin embargo, estudios de los últimos años indican que el cerebro coordina y regula numerosos aspectos de la respuesta inmune innata, y que la inflamación representa un factor crítico y esencial para muchas enfermedades del SNC, como son las enfermedades neurodegenerativas (Wild et al., 2008). Igualmente, la respuesta del sistema inmune innato también desempeña un papel crucial en el dañ…
Medial gastrocnemius muscle and tendon interaction during gait in typically developing children and children with cerebral palsy
2020
1. IntroductionEfficient gait is dependent on optimal interaction between musclesand tendons [1]. Pathological changes in the extensibility of the MGmuscle fascicles, whole muscle-belly and Achilles tendon have beenreported in children with spastic cerebral palsy (CP) [2]. Studying therelative length of these tissues during gait can improve our understandingof their dynamics and, inferably, the control strategies used inCP. In-vivo dynamic ultrasound imaging has been used to visualise theinteraction between the MG muscle and tendon during 3D gait analysis.However, most studies combined ultrasound imaging of one variable(either fascicles or muscle-belly and tendon) with some form ofmusculosk…
Case study : curriculum access accommodations in preschool student with cerebral palsy
2012
Se presenta el contenido de una intervención con un alumno de educación infantil afectado de parálisis cerebral. La intervención se basa en una adaptación de acceso al currículum consistente en el diseño de tareas y actividades educativas con soporte informático accesible al alumno y adecuadas al nivel curricular propio para su edad y curso académico. Esta metodología garantiza al alumno un acceso al currículum minimizando los efectos de sus problemas de movilidad.
Aneurysm clipping following endovascular coil embolization: A report of two cases
2009
Abstract BACKGROUND: Treatment of intracranial aneurysms by Guglielmi detachable coil (GDC) embolization is a useful therapeutic alternative to surgery. This procedure is attractive as a minimally invasive approach to treat cerebral aneurysms; however, is not devoid of complications or failure and retreatment, with either a surgical or endovascular technique, may often be required. CASE REPORTS: Two cases are presented in which surgery was required after coil embolization. In one case, surgical treatment was performed one month later because of regrowth and subsequent bleeding of the aneurysm. In the second case, surgical treatment was carried out six months later because of recanalization …
Thalamic infarctions cause side-specific suppression of vestibular cortex activations.
2005
H2O15-PET was performed during caloric vestibular stimulation of the right and left external ears in eight right-handed patients with acute unilateral infarctions or haemorrhages of the posterolateral thalamus (four right, four left). The posterolateral thalamus is the relay station for ipsi- and contralateral ascending vestibular input to the multiple multisensory vestibular cortex areas. The aim of this study was to evaluate the differential effects of unilateral vestibular thalamic lesions on thalamo-cortical projections, right hemispheric dominance and reciprocal inhibitory visual-vestibular interaction, as well as perceptual and ocular motor consequences during caloric irrigation. The …
Pre- and intraoperative methods of controlling cerebral circulation in giant aneurysm surgery.
1995
The surgical treatment of giant aneurysms usually requires temporary clipping of the aneurysmatic vessel. In planning the surgical approach and in applying temporary clips, the surgeon must consider collateral circulations. The functional integrity of the collateral vessels frequently decides the patient's outcome. In 8 patients with internal carotid artery giant aneurysm, measurements of blood flow velocities in the ipsilateral middle cerebral artery were performed preoperatively with transcranial Doppler ultrasound (TCD) during manual occlusion of the carotid artery at the neck. Three different perfusion patterns were established, and each collateral capacity was rated as insufficient, te…
Cerebral blood flow, computerized tomography and angiography in 562 cases of cerebrovascular insufficiency
1987
The measurement of cerebral blood flow (CBF) in addition to cerebral computerized tomography (CT) and angiography is most reliable in cases of transient ischemic attacks (TIA) and prolonged reversible ischemic neurologic deficits (PRIND). Alterations of CBF can be detected in symptom-free intervals. The cerebrovascular reactivity to CO2 stimulus is regarded as an especially suitable tool to prove the cerebrovascular reserve. If it is diminished, cerebral angiography should be carried out since it will often show major obstructive lesions. Angiography shows no sure correlation between CBF and collateral circulation. Strong opthalmic pathways in unilateral occlusion of the internal carotid ar…
