Objective: Compare if localization of sounds and words discrimination in reverberant environment is different between children with dyslexia and controls.
Method: We studied 30 children with dyslexia and 30 controls. Sound and word localization and discrimination was studied in five angles from left to right auditory fields (-90o, -45o, 0o, +45o, +90o), under reverberant and no-reverberant conditions; correct answers were compared.
Objective: We hypothesized that if the right hemisphere auditory processing abilities can be altered in children with developmental dyslexia (DD), we can detect dysfunction using specific tests.
Method: We performed an analytical comparative cross-sectional study. We studied 20 right-handed children with DD and 20 healthy right-handed control subjects (CS).
Objective: To identify the natural tendencies of hits and calculate the cutoff for a test group of central auditory processes (CAP): binaural fusion, filtered words, dichotic digits, frequency patterns and duration patterns and ambient sounds in normal 5-, 7-, 9- and 11-year-old children.
Material And Methods: We studied 369 children (738 ears) who attend public schools in Puebla City, administering 6 CAP tests (two binaural and four monaural); we used an audiometer at 50dB SL re-threshold at 1 kHz, from a CD recorded at the CCECADET-UNAM-INR (Centre for Applied Science and Technological Development at the National Autonomous University of Mexico and the National Institute for Rehabilitation).
Results: We determined the cutoff points for the six tests.

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.
Introduction And Objective: To identify the auditory or clinical test that has the best correlation with the ear in which we apply the monaural hearing aid in symmetric bilateral hearing loss.
Material And Method: A total of 37 adult patients with symmetric bilateral hearing loss were examined regarding the correlation between the best score in speech discrimination test, corporal laterality, auditory laterality with dichotic digits in Spanish and score for filtered words with monaural hearing aid.
Results: The best correlation was obtained between auditory laterality and gain with hearing aid (0.
Objective: The objective of this study was to document the clinical characteristics of migraine and patterns of medication use in residents > or =15 years old in 12 Latin American urban communities.
Background: Few large-scale population studies have established the symptoms and disability associated with migraine with or without aura in Latin American urban communities or the pattern of medication use in these regions.
Methods: In this study, subjects in 12 urban communities, from 6 Latin American countries, were surveyed with a validated face-to-face interview questionnaire based on International Headache Society criteria for migraine.
Objective: To determine the 1-year point prevalence of migraine among residents > or =15 years old in 12 Latin American urban communities, and record medical consultation preferences of the identified migraineurs.
Background: Prevalence of migraine with or without aura in Latin American urban communities has not been established by large-scale population studies.
Methods: A validated face-to-face interview questionnaire based on International Headache Society criteria was completed for all headache sufferers within selected households, in a cross-sectional study.
Background: Some authors have mentioned that intersensory integration is damaged in children with learning disabilities (LDs), and other investigators point to motor control alterations in the same patients. Thus, we decided to study these hypotheses by means of posturographic recordings.
Methods: A highly selected group of 27 children with LDs was compared with 27 children of control group without LDs.
Objective: This report describes the main clinical features associated with specific reading disability (RD) in a group of 778 school-age children studied in a Neuropsychological Clinic in Mexico City.
Material And Methods: The study was performed retrospectively, using data abstracted from clinical records of subjects seen in 1995-1996. Children were mainly from low and middle economic strata and aged between 6 to 12 years.
