ABSTRACT

INTRODUCTION: The adult brain of mammals preserves the capacity to generate new neurons from neural stem/progenitor cells. The new neurons become part of the already-existing networks by means of a process called 'neurogenesis in the adult brain', which is restricted to regions of the brain with a high degree of plasticity and which are associated to functions that are impaired in Alzheimer's disease. DEVELOPMENT: Despite increasing knowledge, there are still many questions surrounding these neurogenic phenomena, their regulation and their real therapeutic potential in cases of neurodegeneration such as the one referred to here. CONCLUSIONS: We have reviewed the subject of neurogenesis of the adult brain from both the pre-clinical point of view (experimental modelling) and the therapeutic perspective within the framework of Alzheimer's disease.

ABSTRACT

El cerebro adulto de mamíferos conserva la capacidad de generar nuevas neuronas a partir de células troncales/progenitoras neuronales. Las nuevas neuronas se integran a las redes preexistentes a través de un proceso denominado ‘neurogénesis en el cerebro adulto, que está confinado a regiones del cerebro con un alto grado de plasticidad y asociadas a funciones que muestran deterioro en la enfermedad de Alzheimer. Desarrollo. A pesar de lo conocido, permanecen muchos interrogantes alrededor de estos fenómenos neurogénicos, su regulación y su potencial terapéutico real en neurodegeneraciones como la referida. Conclusiones. Hemos revisado el tema de la neurogénesis del cerebro adulto desde el punto de vista preclínico (modelado experimental) y terapéutico en el marco de la enfermedad de Alzheimer(AU)

ABSTRACT

A study is made on 131 patients with presumptive diagnosis of viral hepatitis showing that 25% of patients had acute liver failure as an epiphenomenon of a liver disorder excluding viral hepatitis. These results were obtained through a systematic study of all patients in their various clinical, humoral, and anatomotissular aspects; the latter was achieved through laparoscopy and liver biopsy in the state of the disease.

ABSTRACT

Twenty-seven patients with fasciolasis which was diagnosed through biliary drainage indicated in patients with upper digestive symptoms, particularly of the gastroduodenal portion are presented. The great significance of this procedure in the positive diagnosis of this disease is stressed. The clinical and humoral pictures of these patients are analyzed, and emphasis is made on their poorly defined clinical picture as well as on the little effectiveness of the humoral tests and parasitological studies performed on them. The results of liver macro and microscopic studies on a group of these patients are shown, and the fact that only one patient had lesions attributable to parasitic infestation is pointed out.

ABSTRACT

Se presenta una casuística de 100 laparoscopias realizadas de urgencia en nuestro hospital. Se destaca el valor del procedimiento en los cuadros abdominales agudos donde, además de definir una conducta inmediata, médica o quirúrgica, se obtuvo una correlación de un 97,8 porciento entre los diagnósticos laparoscópicos y operatorio, en los casos intervenidos; se señalan las patologías que con más frecuencia motivaron la exploración laparoscópica. No se informa morbilidad secundaria al procedimiento en los casos estudiados (AU)

ABSTRACT

Se presenta una casuística de 25 casos, estudiados a través de la colangiografía laparoscópica, los cuales eran portadores de vesículas excluidas por colecistografía por vía bucal y endovenosa (E V) o con exámenes radiográficos no concluyentes, y en pacientes portadores de íctero de etiología dudosa. Se destaca el alto valor del procedimiento para llegar a un diagnóstico de certeza en estos casos, especialmente en las vesículas excluidas radiográficamente, donde se demuestra que el 50 porciento de las mismas no corresponden a una patología litiásica. Se recomienda la aplicación del método en todo medio especializado. No se ha informado complicaciones secundarias con el mismo en los casos estudiados (AU)
