Hemorrà gies subaracnoïdals per ruptura d'aneurisma intracranial. Tractament quirúrgic de 100 aneurismes consecutius.
El reconocimiento de la HSA en los Servicios de Urgencias es el primer paso para mejorar los resultados globales de esta grave enfermedad. Deben dirigirse rápidamente a los servicios de neurocirugÃa y operarlos rápidamente, como mÃnimo a los enfermos de grado 1, 2 y 3, evitando el temible resangrado. En nuestra serie de 100 aneurismas consecutivos, la decisión de intervención precoz ha supuesto una mejora en los resultados globales, tanto en mortalidad como en morbilidad. En los grados 4 y 5 la decisión quirúrgica precoz o tardÃa queda abierta a la discusión. La hipertensión-hipervolemia, asà como la administración de antagonistas del Ca (nimodipino) han reducido las secuelas producidas por el espasmo arterial. Los resultados obtenidos en el Hospital de Bellvitge, equiparables a otras series mundiales publicadas, muestran unos buenos resultados en el 71 % de los casos, con una mortalidad de un 12 % que se ha reducido a un 6,3 % en los últimos años. La reincorporación laboral ha sido de un 67 % al año de la intervención
Studies with the Golgi method in central gangliogliomas and dysplastic gangliocytoma of the cerebellum (Lhermitte-Duclos disease)
The rapid Golgi method, combined with current optical and electronmicroscopica1 techniques, was used in three central gangliogliomas and in one dysplastic gangliocytoma of the cerebellum to study the morphology of ganglionic cells. Gangliogliomas were composed of bipolar, fusiform and radiate cells with dense core and clear vesicles in the perikaryon and cellular processes, the number of each cellular type varying from one case to another. These features, together with the fact that isodendritic neurons are considered to be phylogenetically old neurons, suggest that these tumours are composed of 'primitive' neurons that are not homogeneous with regard to their morphology. In contrast, ganglionic cells in dysplastic gangliocytoma are huge cells with long, stereotyped neurites that establish unique asymmetric contacts with neighbouring perikarya and neurites by means of claw-shaped processes covered with synaptic buttons. These morphological characteristics are different from those of any other neuron of the CNS
