Esclerosis múltiple: ventaja izquierda para la lateralidad auditiva en pruebas dicóticas de procesamiento auditivo central y relación de pruebas psicoacústicas con examen de discapacidad-EDEM / Multiple sclerosis: Left advantage for auditory laterality in dichotic tests of central auditory processing and relationship of psychoacoustic tests with the Multiple Sclerosis Disability Scale-EDSS

OBJETIVO: Evaluar los trastornos en procesos centrales de la audición, en pacientes con esclerosis múltiple, enfatizando en lateralidad auditiva mediante la aplicación de pruebas psicoacústicas e identificar la relación de estas con funciones de la Escala de Discapacidad en Esclerosis Múltiple (EDEM). MÉTODO: En 26 individuos con esclerosis múltiple y 26 controles se aplicaron escala de depresión (HADS), EDEM y 9 pruebas psicoacústicas para estudiar trastornos en los procesos centrales de la audición. Se efectuaron pruebas de correlación entre EDEM y pruebas psicoacústicas. RESULTADOS: Siete de 9 pruebas psicoacústicas fueron diferentes significativamente (p < 0,05); derecha o izquierda (14/19 exploraciones) respecto al grupo control. En dígitos dicóticos la izquierda mostró ventaja de aciertos respecto al predominio usual de dígitos dicóticos en la derecha. Hubo correlación significativa en 5 pruebas psicoacústicas y funciones específicas de la Escala de Discapacidad en Esclerosis Múltiple. CONCLUSIÓN: Conviene investigar la ventaja del oído izquierdo detectada como expresión de influencias deficientes del cuerpo calloso y de atención en esclerosis múltiple. Hay correlación entre pruebas psicoacústicas con funciones específicas de EDEM

OBJECTIVE: To evaluate the central auditory processing disorders in patients with multiple sclerosis, emphasizing auditory laterality by applying psychoacoustic tests and to identify their relationship with the Multiple Sclerosis Disability Scale (EDSS) functions. METHOD: Depression scales (HADS), EDSS, and 9 psychoacoustic tests to study CAPD were applied to 26 individuals with multiple sclerosis and 26 controls. Correlation tests were performed between the EDSS and psychoacoustic tests. RESULTS: Seven out of 9 psychoacoustic tests were significantly different (P<.05); right or left (14/19 explorations) with respect to control. In dichotic digits there was a left-ear advantage compared to the usual predominance of RDD. There was significant correlation in five psychoacoustic tests and the specific functions of EDSS. CONCLUSION: The left-ear advantage detected and interpreted as an expression of deficient influences of the corpus callosum and attention in multiple sclerosis should be investigated. There was a correlation between psychoacoustic tests and specific EDSS functions

Procesos centrales de la audición evaluados en español en escolares con dislexia y controles. Pruebas de fusión binaural y de palabras filtradas / Assessment of central auditory processes in evaluated in Spanish in children with dyslexia and controls. Binaural Fusion Test and Filtered Word Test

Objetivo: El objetivo es evaluar la habilidad para distinguir palabras usando dos pruebas psicoacústicas verbales de procesos centrales de la audición (PCA) en español: la prueba de fusión binaural (PFB) y la prueba de palabra filtrada (PPF), en niños con dislexia y en niños controles. Métodos: Cuarenta niños con dislexia seleccionados de grupos de terapia y 40 niños seleccionados de 298 niños de una escuela pública como controles, pareados por sexo y edad. Resultados: Hubo predominio masculino 2/l en los niños disléxicos. Los promedios de acierto para la PFB fueron del 65 al 66% para los niños con dislexia y del 78 al 80% para los niños control. Para la PPF éstos fueron del 50 al 55% para los niños con dislexia y del 67 al 71% para los controles (t de Student <0,05). Conclusiones: Estos resultados contribuyen a evidenciar alteraciones de los PCA para estímulos psicoacústicos verbales en niños con dislexia. Se propone evaluar cada paciente con pruebas de PCA para definir el plan de rehabilitación (AU)

Objectives: The aim is to assess the ability to discriminate words, using two psychoacoustic verbal tests of Central auditory processes in Spanish: Binaural Fusion Test (BFT in its Spanish version) and Filtered Word Test (FWT in its Spanish version) in children with dyslexia and controls. Methods: One group of 40 dyslexic children was receiving therapy for dyslexia at the time of the tests. 40 children without dyslexia were selected as controls, out of 298 children who attended a public school. Results: The rate of males to females was 2/1 in the dyslexic group. The average correct answers for the BFT were 65–66% in dyslexic group and 75–80% in the control group. For the FWT they were 50–54% in the dyslexic group and 67–71% in the control group (student t <0.05). Conclusions: These results contribute to make evident disorders in central auditory processing in children with dyslexia. We suggest using the tests with each patient in order to elaborate a rehabilitation plan (AU)

[Vestibular findings in patients with Vogt-Koyanagi-Harada syndrome]. / Hallazgos vestibulares en pacientes con síndrome de Vogt-Koyanagi-Harada.

OBJECTIVE: To identify and describe vestibular abnormalities in patients with Vogt-Koyanagi-Harada syndrome (VKH). MATERIALS AND METHOD: Prospective, cross-sectional, observational and descriptive study. Patients with VKH referred by an ophthalmological center, were interrogated and physically examined in search of signs of vestibular abnormalities, and if positive, they underwent videonystagmography, computerized dynamic posturography, tonal audiometry and tympanometry. RESULTS: Out of 21 patients with VKH, only 10 were included in the study due to presenting data of vestibular abnormalities (10/10 with vestibular symptoms and 9/10 with abnormalities in the physical exploration). The age average was 37.8 years. The videonystagmography was mainly abnormal in ocular saccades test (10/10). The posturography showed a higher alteration of the visual (4/10) and vestibular (4/10) afferents. A diagnosis of benign paroxysmal positional vertigo was mostly concluded (6/10). None presented abnormalities of the middle ear nor data of central pathology, 6/10 presented abnormalities in tonal audiometry. CONCLUSIONS: Peripheral vestibular disorder is often present in the population with VKH.

Objetivo: Identificar y describir alteraciones vestibulares en pacientes con síndrome de Vogt-Koyanagi-Harada (VKH). Material y método: Estudio prospectivo, transversal, observacional y descriptivo. Se interrogó y exploró físicamente a pacientes con VKH referidos de un centro oftalmológico, en busca de datos de alteración vestibular. De ser positiva, se les realizó videonistagmografía, posturografía dinámica computarizada, audiometría tonal y timpanometría. Resultados: De 21 pacientes con VKH, sólo se incluyeron a 10 por presentar datos de alteración vestibular (10/10 con síntomas vestibulares, 9/10 con alteraciones en la exploración física). Media de edad, 37,8 años. Videonistagmografía principalmente alterada en prueba de sacadas oculares (10/10). Posturografía con mayor alteración de las aferencias visual (4/10) y vestibular (4/10). Se concluyó mayoritariamente el diagnóstico de vértigo postural paroxístico benigno (6/10). Ninguno presentó alteración del oído medio ni datos de afección central; 6/10 tuvieron alteraciones en la audiometría tonal. Conclusiones: La población con VKH frecuentemente sufre afección vestibular periférica (AU)
