Is semantic impairment a predictive sign for Alzheimer disease?
This review describes the performance of persons with Alzheimer disease and mild cognitive impairment in some semantic tasks reported in the literature due to their diagnostic and prognostic values. Most of the studies reviewed included visual confrontation naming and verbal fluency tasks. There is a controversy about whether naming deficits are due to a degradation of semantic contents, diffic...


Utilidad de los potenciales evocados visuales con patrón invertido en el diagnóstico de la dislexia
En los disléxicos se ha demostrado que existe una alteración de la vía magnocelular, lo cual ha sido corroborado con estudios electrofisiológicos. El objetivo de este estudio fue determinar la utilidad de los potenciales evocados visuales con patrón invertido (PEVp) en el diagnóstico de la dislexia. Estudio comparativo en el que se estudiaron 16niños disléxicos del Instituto Nacional de...
Variabilidad en la comprensión gramatical de mayores sanos: diferencias en función de la reserva cognitiva
En el presente estudio se analizan las relaciones entre la variabilidad interindividual (diversidad) en vocabulario, comprensión de oraciones y denominación y la reserva cognitiva (RC) estimada en adultos mayores. Participaron 83 personas de edades comprendidas entre los 60 y los 75años. Se empleó el Cuestionario de Reserva Cognitiva para estimar la RC. Para obtener las medidas de denominac...

Short-Term Changes in Ocular Biometry and Refraction After Discontinuation of Long-Term Orthokeratology
To assess refractive and biometric changes 1 week after discontinuation of lens wear in subjects who had been wearing orthokeratology (OK) contact lenses for 2 years. Twenty-nine subjects aged 6 to 12 years and with myopia of −0.75 to −4.00 diopters (D) and astigmatism of ≤1.00 D participated in the study. Measurements of axial length and anterior chamber depth (Zeiss IOLMaster), corneal ...
Investigation of Tear Osmolarity Using the TearLab Osmolarity System in Normal Adults in Saudi Arabia
To investigate the repeatability and average tear osmolarity using the new lab-on-chip TearLab technology device in normal subjects living in Saudi Arabia, a hot climate country, and to compare the average readings with data from previous studies. Thirty healthy young adults (13 males and 17 females) who ranged in age from 20 to 40 years (mean±SD: 28.57±5.58 years) with no symptoms of dry eye...
Topical Tacrolimus 0.03% as Sole Therapy in Vernal Keratoconjunctivitis: A Randomized Double-Masked Study
