ABSTRACT
Introducción: El procesamiento sensorial determina e influencia el nivel de desarrollo que presentan los individuos en la infancia y cuando se afecta alguno de los sistemas que lo integran, se alteran dominios del desarrollo que impiden a los niños desenvolverse de manera adecuada en su entorno. Objetivos: Describir y comparar el procesamiento sensorial de los niños con trastorno específico del lenguaje y con desarrollo típico del lenguaje. Métodos: La muestra estuvo conformada por 60 niños con edades de 4 a 5 años de la escuela especial de lenguaje San Clemente, asignados a dos grupos de acuerdo con la presencia o ausencia de trastorno específico del lenguaje. El procesamiento sensorial se evaluó mediante la escala de procesamiento sensorial. Se evaluó el tipo de distribución de las variables de la escala para su posterior análisis. Resultados: Los niños con trastorno específico del lenguaje obtuvieron 275 puntos y se ubicaron por debajo del puntaje de corte, en cambio los menores con desarrollo típico obtuvieron 309 puntos y se situaron por sobre el puntaje de corte. Es decir, los niños con trastorno específico del lenguaje presentaron un procesamiento sensorial más bajo en comparación con los niños que poseen desarrollo típico del lenguaje con diferencias significativas en el sistema auditivo y propioceptivo. Conclusiones: Los niños con trastorno específico del lenguaje exhiben un desempeño más bajo en tareas de procesamiento sensorial, es por ello, que este último debe ser considerado en la evaluación y diagnóstico de niños con este trastorno para generar un abordaje más integral.
Introduction: Sensory processing determines and influences the level of development presented by individuals in childhood and when any of the systems that integrate it are affected. Developmental domains are altered and they prevent children from developing adequately in their environment. Objectives: To describe and compare sensory processing in children with specific language impairment and typical language development. Methods: The sample consisted of 60 children aged 4 to 5 years from the San Clemente Special Language School, whom were assigned to two groups according to the presence or absence of specific language disorder. Sensory processing was assessed using the sensory processing scale. The type of distribution of the scale variables was evaluated for further analysis. Results: Children with specific language disorder obtained 275 points and were below the cut-off score, while children with typical development obtained 309 points and were above the cut-off score. That is, children with specific language disorder have lower sensory processing compared to children with typical language development with significant differences in the auditory and proprioceptive system. Conclusions: Children with specific language disorder show lower performance in sensory processing tasks, which is why the latter should be considered in the evaluation and diagnosis of children with this disorder to generate a more comprehensive approach.
ABSTRACT
The metazoan parasite fauna of Hippoglossina macrops (n = 123) from northern Chile (30°S) is quantitatively described for the first time, and the role of host age and sex was evaluated. Twelve parasite species were recovered, including 5 ectoparasites (2 Monogenea, 2 Copepoda and 1 Piscicolidae) and 7 endoparasites (1 Digenea, 3 Cestoda, 2 Acanthocephala, and 1 Nematoda). The copepod Holobomolochus chilensis, the monogenean Neoheterobothrium sp., the adult acanthocephalan Floridosentis sp. and the hirudinean, Gliptonobdella sp. are new geographical and host records. The most prevalent ectoparasitic species were the monogenean, Neoheterobothrium sp. and the copepod, H. chilensis. Among endoparasites, the acanthocephalans Floridosentis sp. and Corynosoma australe were most prevalent and abundant. Prevalence and mean intensity of infection for most parasitic species were not affected by host sex, however the prevalence of Floridosentis sp. was significantly greater in males. Intensity of infection was positively correlated with host age for Neoheterobothrium sp., and negatively correlated for Floridosentis sp. and H. chilensis. The helminth species richness of the host H. macrops was lower compared to related flatfishes from the Northern Hemisphere. The relationship of the helminth fauna of H. macrops, its feeding habits and ecological habitats are discussed
