Características neuropsicológicas de crianças com dislexia

The aim of this study was to identify the neuropsychological characteristics of dyslexic children. Seventy-three children underwent neuropsychological assessment and were divided into two groups: a group with dyslexia (DG; n=39) and a control group (CG; n= 34). A general linear model showed a significant difference between the groups regarding the following abilities: reading, writing and mathematics; forward and backward digit span tasks; semantic and phonological fluency; number of completed categories and total number of cards in the Wisconsin Cards Sorting Test; as well as right and left discrimination on self and on other. These results suggest impairment in executive functions, phonological working memory and semantic memory among dyslexic children, rather than impairment of just phonological abilities, as suggested in previous studies.O objetivo deste trabalho foi identificar as características neuropsicológicas de crianças com dislexia. Foram incluídas 73 crianças divididas em dois grupos: um grupo composto por crianças disléxicas (GD; n=39), e um grupo controle (GC; n= 34). A análise de modelo linear geral mostrou diferença significativa entre os grupos nas habilidades de leitura, escrita, matemática, dígitos ordem direta, dígitos ordem inversa, fluência semântica e fonológica, número de categorias e total de cartas do Teste de Classificação de Cartas de Wisconsin, discriminação direita e esquerda em si e no outro. Esses resultados demonstram que podem existir déficits nas funções executivas, memória operacional fonológica e memória semântica e não apenas nas habilidades fonológicas.Universidade Presbiteriana MackenzieUniversidade Federal de São Paulo (UNIFESP)Universidade Federal de São Paulo, EPM, São Paulo, BrazilSciEL

Quality of life in elderly with dizziness

Dizziness is frequent in elderly people. AIMS: To evaluate the Quality of Life (QoL) in elderly subjects with dizziness, relate it with gender and age. MATERIAL AND METHOD: A prospective study comprising 120 elderly patients with dizziness evaluated with Brazilian versions of the Whoqol-bref and the dizziness handicap inventory (DHI). The factor analysis (FA), the Mann Whitney and Kruskal Wallis tests, and the Spearman correlation were applied to study the results. RESULTS: The most compromised domains were the DHI physical domain and the Whoqol-bref physical and environment domains. FA resulted in 3 factors in the DHI and 5 factors in the Whoqol-bref. There was a moderate correlation (-0.596) in the total scores of both instruments. Males had a better QoL in the environment perception and introspectivity and health perception factors of the Whoqol-bref test. Females had a better QoL in the functionality perception factor of the Whoqol-bref test. There were no significant age differences. CONCLUSIONS: Elderly patients with dizziness have a worse QoL. Elderly females with dizziness have worse QoL scores in environment perception and introspectivity and health perception and better QoL in the functionality perception factor compared to elderly males.Tontura é muito frequente em idosos. OBJETIVOS: Avaliar a qualidade de vida (QV) em idosos vestibulopatas e relacioná-la com o gênero e a faixa etária. MATERIAL E MÉTODO: Estudo prospectivo que incluiu série de 120 casos de idosos com tontura que foram avaliados por meio das versões brasileiras dos questionários Whoqol-bref e Dizziness Handicap Inventory (DHI). Os resultados obtidos foram submetidos à Análise Fatorial (AF) e aos testes de Mann Whitney, Kruskal Wallis e correlação de Spearman. RESULTADOS: O domínio físico avaliado pelo DHI, e o físico e o ambiental do Whoqol-bref foram os mais comprometidos. A AF resultou em 3 fatores no DHI e 5 no Whoqol-bref: Houve moderada correlação (-0,596) entre o escore total de ambos os instrumentos. Os homens apresentaram melhor QV nos fatores percepção ambiental e introspectividade e percepção da saúde do Whoqol-bref. As idosas obtiveram melhor QV no fator percepção da funcionalidade do Whoqol-bref. Não houve diferenças significantes entre os fatores dos dois instrumentos por faixa etária. CONCLUSÕES: Idosos vestibulopatas apresentam QV prejudicada. As idosas vestibulopatas apresentam pior QV em relação aos fatores percepção ambiental e introspectividade e percepção da saúde e melhor QV em relação ao fator percepção da funcionalidade que os homens.UNIFESP-EPMUNIBAN Programa de Mestrado em Reabilitação do Equilíbrio Corporal e Inclusão SocialUNIFESP-EPM Departamento de Otorrinolaringologia e Cirurgia de Cabeça e PescoçoUNIFESP, EPM, Depto. de Otorrinolaringologia e Cirurgia de Cabeça e PescoçoSciEL

Taxonomic revision of Galeocharax (Characiformes: Characidae: Characinae)

ABSTRACT The taxonomy of Galeocharax, a genus of freshwater fishes distributed in most South American cis-Andean river systems, except the rio Negro, rio São Francisco and rio Xingu basins and the eastern drainages of Brazil, is herein revised. A total of 1229 specimens were examined from which 680 had meristic and morphometric data taken. Osteological and morphological features were also examined through radiographs, scanning electron microscopy and in cleared and stained specimens. Three of the four species previously considered as valid are herein recognized: Galeocharax humeralis from rio Paraguay and lower rio Paraná basins; Galeocharax goeldii, from rio Madeira basin, with records of geographical distribution expanded to the río Madre de Dios, río Beni, rio Mamoré and rio Guaporé basins and Galeocharax gulo, which is widespread throughout rio Amazonas, río Orinoco, rio Tocantins, and upper rio Paraná basins. Galeocharax knerii is herein considered a junior synonym of Galeocharax gulo. A key to species of Galeocharax is presented

Systematics of Lamontichthys Miranda-Ribeiro (Siluriformes: Loricariidae), with the description of two new species

The taxonomic revision of the genus Lamontichthys Miranda-Ribeiro, based on the examination of 164 specimens of different river drainages throughout the Amazon basin, revealed the presence of six species of which two are new. Lamontichthys filamentosus occurs in the upper and middle portions of the rio Amazonas basin; L. llanero in the río Orinoco basin; L. maracaibero in the lago Maracaibo basin; and L. stibaros in the upper río Amazonas basin. Lamontichthys avacanoeiro, new species, occurs in the upper rio Tocantins basin; and L. parakana, new species, in the lower rio Tocantins basin. The new species represent a considerable extension in the so far known distribution of the genus. A parsimony analysis, including 87 osteological and external morphological characters from Lamontichthys and related taxa (total of 16), resulted in three most parsimonious trees with 194 steps (CI = 0.73 and RI = 0.78). The hypothesis of monophyly of Lamontichthys is corroborated and supported by six derived characters. Within Lamontichthys two monophyletic assemblages are recognized, one includes L. avacanoeiro and L. stibaros, the other includes L. maracaibero and the clade formed by L. filamentosus and L. llanero. The relationships of Lamontichthys parakana, a species that was not included in the phylogenetic analysis is discussed. The monophyly and relationships of the monotypic genus Pterosturisoma microps are also discussed
