[C3c activation and intrathecal biosynthesis in children suffering from eosinophilic meningoencephalitis due to Angiostrongylus cantonensis]. / Activación y biosíntesis intratecal de C3c en niños con meningoencefalitis eosinofilica por Angiostrongylus cantonensis.

INTRODUCTION: Eosinophilic meningoencephalitis due to Angiostrongylus cantonensis is an emergent infectious disease in our area. The objective of the present paper is to determine if the activation of the complement system was taken placed with the C3c production in cerebrospinal fluid. PATIENTS AND METHODS: 14 patients with an average age 4.5 years were studied. In such patients a lumbar punction was performed. C3c was quantified in serum and cerebrospinal fluid by radial immunodiffusion. RESULTS: Median cell number was 396 x 10(-6)/L with an average of 8.8% of eosinophils. Main symptoms were headache, vomiting and fever. Meningeal signs were present in 50% of the patients. C3c intrathecal synthesis occurred in 13 patients (92.8%). CONCLUSION: It was demonstrated the participation of complement system in third-stage larvae destruction in cerebrospinal fluid.

Activación y biosíntesis intratecal de C3c en niños con meningoencefalitis eosinofílica por Angiostrongylus cantonensis / C3c Activation and intrathecal biosythsis in children suffering form eosinohilic meningoencephalitis due to angiostrongylus cantonensis

Introducción. La meningoencefalitis por Angiostrongylus cantonensis es una enfermedad infecciosa emergente. El objetivo del presente trabajo es determinar si se produce la activación del sistema del complemento con la consiguiente producción de C3c en el líquido cefalorraquídeo. Pacientes y métodos. Se estudiaron 14 pacientes con edad promedio de 4,5 años a los que se les realizó una punción lumbar diagnóstica. La cuantificación de C3c y albúmina en el suero y el líquido cefalorraquídeo se realizó en placas de inmunodifusión radial. Resultados. El número de células promedio en el líquido cefalorraquídeo fue de 396 × 10–6 células/L. En la cuenta diferencial de células se apreció el 8,8% de eosinófilos promedio. Los principales síntomas de los pacientes fueron cefaleas, vómitos y fiebre. El 50% presentó algún signo meníngeo. Se comprobó la existencia de síntesis intratecal de C3c en 13 de los pacientes estudiados (92,8%). Conclusión. Se demuestra la participación del sistema de complemento en la destrucción de la larva del tercer estadio del parásito en el líquido cefalorraquídeo (AU)

Seasonal distribution and evolving forms of multiple sclerosis patients diagnosed from April 2004 to November 2007

Multiple sclerosis (MS) was first reported in Cuba in 1965. The most frequent appearance is observed in the first six months of the year. Objetive: To determine the seasonal distribution and evolving forms of MS patients diagnosed with the disease between April 2004 and November 2007. Twenty-one patients with suspected MS and 42 outbreaks were studied. Patients were classified according to Lublin and Revingold's criteria for clinical forms and according to McDonald. Most patients were classified in outbreak and remission and only two patients classified as primary-progressive multiple sclerosis. The higher number of outbreaks occurred in the first two quarters of the year. It is recommended to study further weather variables that may be related to the emergence of these outbreaks in our environment(AU)

La esclerosis múltiple (EM) fue reportada en Cuba por primera vez en 1965. Se ha venido observando la aparición más frecuente en los primeros seis meses del año. Objetivo: Determinar la distribución estacional y formas evolutivas de EM en pacientes con diagnóstico de esta enfermedad entre abril 2004 y noviembre 2007. Se estudiaron 21 pacientes con sospecha de EM y un total de 42 brotes. Los pacientes fueron clasificados según los criterios de Lublin y Revingold para las formas evolutivas y según los criterios de McDonald. Solo dos pacientes clasificaron en la forma evolutiva progresiva primaria; los primeros dos trimestres del año fueron los de mayor número de brotes. Se recomienda profundizar en las variables climatológicas que pudieran tener vínculo con la aparición de estos brotes en nuestro medio(AU)

[Productivity and visibility of Cuban neuroscientists: bibliometric study of the period 2001-2005]. / Productividad y visibilidad de los neurocientíficos Cubanos: estudio bibliométrico del período2001-2005.

INTRODUCTION: Neurosciences have an important place inside the scientific development of Ibero American countries, and particularly in Cuba. The objective of the current work is to analyze the productivity and visibility of Cuban neuroscientists in the period 2001-2005, and the value of H index as evaluation tool. MATERIALS AND METHODS: Web of Science and Scopus were the databases used as information sources. The 24 Cuban neuroscientists in Web of Science were identified, and their scientific production in Scopus was retrieved. For each author, in each database, the following indicators were calculated: total number of published authors, total number of cited articles, proportion of cited articles, total number of citations received, average of citations received by article, and H index. RESULTS: Some variations in the calculated indicators were observed in Scopus with respect to Web of Science. The wide coverage of this database exerted influence on the increment of scientist's productivity, as well as on the increment of H index values. CONCLUSIONS: The possible incorporation of citation analysis, as well as other indicators derived, in the processes of evaluation and analysis of the scientific activity was considered, in order to evaluate the advances in the Neurosciences field.
