RESUMO

OBJECTIVE: Dyslexia is the difficulty of children in learning to read and write as results of neurological deficiencies. The objective was to test the Phonological awareness (PA) and Sinusoidal amplitude modulation (SAM) threshold in children with Phonological dyslexia (PD). METHODS: We performed a case-control, analytic, cross sectional study. We studied 14 children with PD and 14 control children from 7 to 11 years of age, by means of PA measurement and by SAM test. The mean age of dyslexic children was 8.39 years and in the control group was 8.15. RESULTS: Children with PD exhibited inadequate skills in PA, and SAM. We found significant correlations between PA and SAM at 4 Hertz frequency, and calculated regression equations that predicts between one-fourth and one-third of variance of measurements. CONCLUSION: Alterations in PA and SAM found can help to explain basis of deficient language processing exhibited by children with PD.

RESUMEN Objetivo La Dislexia es la dificultad en niños de aprender a leer y escribir como resultado de una deficiencia neurológica. Nuestro objetivo fue probar la Conciencia fonológica (CF) y la Modulación sinusoidal de la amplitud (MSA) en niños con Dislexia fonológica (DF). Métodos Realizamos un estudio analítico, transversal, de casos y controles. Estudiamos la CF y la MSA en 14 niños con DF y 14 controles de 7–11 años. La edad media de los niños con DF fue de 8.39 años y de los controles fue 8.15. Resultados Los niños con DF presentaron deficiencias en CF y en MSA. Encontramos correlaciones entre CF y MSA en la frecuencia de 4 Hertzios (Hz), calculamos ecuaciones de regresión que predijeron de un cuarto a un tercio de la varianza de las mediciones. Conclusión Las deficiencias en CF y en MSA pueden ayudar a comprender las alteraciones en el procesamiento del lenguaje presentadas por los niños con DF.

RESUMO

To assess the influence of the body mass index (BMI) on the occurrence of falls in adults with type 2 diabetes mellitus, receiving primary health care. We collected data from 134 patients (56.7±9.4 y.o.), none of them were seeking medical care due to sensory or balance decline. During the first evaluation, they reported falls, replied to a questionnaire of symptoms related to balance and had a sensory evaluation. After a 6 months follow-up, they reported falls again and, according to the occurrence of falls during the preceding year, patients were classified in 2 groups: no falls (N=92) and falls (N=42). The occurrence of falls was related to BMI, gender and age. Compared to patients with no falls, patients with falls had a greater BMI and comprised a higher proportion of patients with a BMI ≥35; patients with a BMI ≥35 were younger than patients with a BMI <35. A total symptom score ≥4 allowed the classification of 77.7% of the patients with falls and 59.5% with no falls. In adults with type 2 diabetes mellitus, a BMI ≥35 may have an influence on balance and the occurrence of falls, which might be independent from aging. Patients should be aware of this risk and receive counsel on modifiable risk factors.

RESUMO

AIM: To assess the influence of peripheral neuropathy, gender, and obesity on the postural stability of patients with type 2 diabetes mellitus. METHODS: 151 patients with no history of otology, neurology, or orthopaedic or balance disorders accepted to participate in the study. After a clinical interview and neuropathy assessment, postural stability was evaluated by static posturography (eyes open/closed on hard/soft surface) and the "Up & Go" test. RESULTS: During static posturography, on hard surface, the length of sway was related to peripheral neuropathy, gender, age, and obesity; on soft surface, the length of sway was related to peripheral neuropathy, gender, and age, the influence of neuropathy was larger in males than in females, and closing the eyes increased further the difference between genders. The mean time to perform the "Up & Go" test was 11.6 ± 2.2 sec, with influence of peripheral neuropathy, gender, and age. CONCLUSION: In order to preserve the control of static upright posture during conditions with deficient sensory input, male patients with type 2 diabetes mellitus with no history of balance disorders may be more vulnerable than females, and obesity may decrease the static postural control in both males and females.
