RESUMO

INTRODUCTION AND METHODS: In order to compare the magnetic resonance image characteristics of individuals belonging to pedigrees carrying the mutation E280A-PS1 associated to early onset Alzheimer disease, coming from Antioquia, Colombia, 78 individuals were studied. 47 of them were carriers of the mutation, 23 of those presented symptoms and 31 individuals being controls (non carriers of the mutation). RESULTS: In summary, significative differences were appreciated between symptomatic individuals and those asymptomatic. There was not significant difference between asymptomatic carriers and the controls. The presence of the perihippocampal fissure constituted a difference statistically significant between the symptomatic individuals and those carriers asymptomatic and between the symptomatic ones and the controls. The interuncal distance increased significantly was another difference between symptomatic and asymptomatic individuals and among symptomatic and control group. The lobar atrophy and the ventriculomegaly were found in symptomatic individuals and they correlate with the disorder graveness. There was not significance in the presence of infarcts and/or hippocampal hyperintensities. CONCLUSION: These results corroborate the statement that magnetic resonance image is very useful in the diagnosis and follow-up of individuals affected by early onset Alzheimer disease.

RESUMO

INTRODUCTION: In this investigations, was carried out a neurocysticercosis (NC) prevalence study during seven months in the Instituto Neurológico de Antioquia with the purpose of known neurocysticercosis frequency as cause of epilepsy in patients older than ten years that we attended in our institute. MATERIAL AND METHODS: Computerized tomographies (CT) were made to 503 patients, with epilepsy, 24.7% of them were CT positive for NC. Cysticercosis enzyme linked immunoelectrotransfer blot (EITB) and enzyme linked immunoabsorbent assay (ELISA) test were made to 178 patients, 19.6% were EITB positive for NC and 5% ELISA positive for NC. Results. From this result it is possible to infer that about 8% of the 503 patients with epilepsy had cysticercosis, according to EITB that is the golden assay for NC. The CT and ELISA test had 94.3% and 27.7% sensitivity, respectively, according to EITB. The specificity of the CT for NC was 49.2% and specificity for ELISA test was 100% as compared to EITB. The multivariate analysis with logistic regression allowed to establish association of positive EITB with factors such as male sex, eating pork, headaches and multiple lesions in CT. CONCLUSIONS: Prevention and education actions are necessary for the interruption of the neurocysticercosis transmission chain in order to diminish the high prevalence of epilepsy in the country and its complication and consequences.
