ABSTRACT

ABSTRACT Objective This study aimed to determine the prevalence of nonsyndromic congenital sensorineural hearing loss at the Hospital Universitario San Ignacio, Bogotá, Colombia, and to describe the risk factors associated with this condition. Materials and Methods A prospective, observational cross-sectional study with bivariate analysis was conducted. A three-phase process using the Otoacoustic Emissions test screened all live newborns between June 2013 and June 2014. Negative cases were confirmed by Automated Auditory Brainstem Response test. Results A total of 962 newborns were screened with Otoacoustic Emissions test bilaterally: 401 males (46.36%), 464 females (53.64%). The mean weight was 2 798.10 g (95%CI: 2 766.51 - 2 839.76). The mean height was 48.60 cm (95%CI: 48.38 - 48.79). The mean age was 16.24 days (95%CI: 15.47 - 17.01). The mean maternal age was 27.37 years (95%CI: 26.76 - 27.98). There was a family history of hearing loss in 9.48% of the cases (n=90), and a family history of genetic diseases in 100 cases (10.56%). There were 14 cases of TORCH infections (1.45%), 375 admissions to the NICU (39.06%), 160 cases of neonatal jaundice (20.1%), and 79 cases of postpartum infections (8.21%). One live newborn presented with microtia. Conclusions The prevalence of congenital sensorineural hearing loss was 0.31% in both ears, and 0.11% in one ear. Currently, Colombia lacks a public universal newborn hearing screening program, and its future implementation faces great challenges.(AU)


RESUMEN Objetivos Este estudio busca determinar la prevalencia de la hipoacusia neurosensorial congénita no sindrómica en el Hospital Universitario San Ignacio de Bogotá, Colombia, y describir sus factores de riesgo. Materiales y Métodos Estudio observacional, transversal y prospectivo con análisis bivariado. Todos los nacidos vivos entre junio de 2013 y junio de 2014 fueron tamizados con Emisiones Otoacusticas. Los casos negativos fueron confirmados con Potenciales Evocados Auditivos de Tronco Cerebral. Resultados Un total de 962 neonatos fueron tamizados de forma bilateral con Emisiones Otoacústicas: 401 de sexo masculino (46,36%) y 464 de sexo femenino (53,64%). El peso promedio fue de 2 798,10 g (IC95%: 2 766,51 - 2 839,76). La talla promedio fue de 48.60 cm (IC95%: 48,38 - 48,79). La edad promedio fue de 16,24 días (IC95%: 15,47 -17,01). La edad materna promedio fue de 27,37 años (IC95%: 26,76 - 27,98). Se encontró historia familiar de hipoacusia en 9.48% de los casos (n=90) e historia familiar de enfermedades genéticas en 100 casos (10,56%). Hubo 14 casos de infecciones por TORCH (1,45%), 375 admisiones a la UCI Neonatal (39,06%), 160 casos de ictericia neonatal (20,1%) y 79 casos de infecciones postnatales (8,21%).

ABSTRACT

Abstract Introduction With the need for hearing screenings increasing across multiple populations, a need for automated options has been identified. This research seeks to evaluate the hardware requirements for automated hearing screenings using a mobile application. Objective Evaluation of headphone hardware for use with an app-based mobile screening application. Methods For the purposes of this study, hEAR, a Bekesy-based mobile application designed by the research team, was compared with pure tone audiometric tests administered by an audiologist. Both hEAR and the audiologist's test used 7 frequencies (125 Hz, 250 Hz, 500 Hz, 1,000 Hz, 2000 Hz, 4,000 Hz and 8,000 Hz) adopting four different sets of commercially available headphones. The frequencies were regarded as the independent variable, whereas the sound pressure level (in decibels) was the dependent variable. Thirty participants from a university in Texas were recruited and randomly assigned to one of two groups, whose only difference was the order in which the tests were performed. Data were analyzed using a generalized estimating equation model at α = 0.05. Results Findings showed that, when used to collect data with the mobile app, both the Pioneer HDJ-2000 (Pioneer, Bunkyo, Tokyo, Japan) (p> 0.05) and the Sennheiser HD280 Pro (Sennheiser, Wedemark, Hanover, Germany) (p> 0.05) headphones presented results that were not statistically different from the audiologist's data across all test frequencies. Analyses indicated that both headphones had decreased detection probability at 4kHz and 8kHz, but the differences were not statistically significant. Conclusion Data indicate that a mobile application, when paired with appropriate headphones, is capable of reproducing audiologist-quality data.

ABSTRACT

Studies have demonstrated that conventional hearing protectors interfere with sound localization. This research examines possible benefits from advanced communications devices. Horizontal plane sound localization was compared in normal-hearing males with the ears unoccluded and fitted with Peltor H10A passive attenuation earmuffs, Racal Slimgard II communications muffs in active noise reduction (ANR) and talk-through-circuitry (TTC) modes and Nacre QUIETPRO TM communications earplugs in off (passive attenuation) and push-to-talk (PTT) modes. Localization was assessed using an array of eight loudspeakers, two in each spatial quadrant. The stimulus was 75 dB SPL, 300-ms broadband noise. One block of 120 forced-choice loudspeaker identification trials was presented in each condition. Subjects responded using a laptop response box with a set of eight microswitches in the same configuration as the speaker array. A repeated measures ANOVA was applied to the dataset. The results reveal that the overall percent correct response was highest in the unoccluded condition (94%). A significant reduction of 24% was observed for the communications devices in TTC and PTT modes and a reduction of 49% for the passive muff and plug and muff with ANR. Disruption in performance was due to an increase in front-back reversal errors for mirror image spatial positions. The results support the conclusion that communications devices with advanced technologies are less detrimental to directional hearing than conventional, passive, limited amplification and ANR devices.

ABSTRACT

There has been controversy in the health professions about the necessity for newborn infant hearing screening. It is well accepted that patient history or a birth that places the infant in the high-risk registry (HHR) can identify 50 of all infants born with permanent bilateral hearing loss. Two major factors which have been cited as reasons for not screening the well-baby nursery have been poor cost effectiveness and the lack of documentation as to the benefits derived from early identification and intervention. Recent technological developments and published data are presented which indicate that economical well-baby hearing screening can be done in any setting, and that the language acquisition of the infant is permanently affected if the intervention is not done in the first six months after birth

ABSTRACT

La comprobación de la existencia de sonidos generados en las células cilíadas externas del oído y que pueden ser medidos mediante el instrumental adecuado, se basa en las fascinantes experiencias que comenzaron hace sólo 20 años con la verificación hecha por David Kemp, y que modificaron sustancialmente el conocimiento sobre la fisiología coclear. Hoy, los procedimientos están reglados, aceptados universalmente y se vienen aplicando a distintos campos de la clínica y de la investigación, tales como el screening de audición en recién nacidos, el estudio de ototoxicidad, etc. En el presente trabajo se pasa revista sucesivamente a los distintos tipos de otoemisiones acústicas, a las aplicaciones clínicas más conocidas y se propone su instrumentación en distintas áreas de la salud ocupacional y de la medicina legal del trabajo, acompañándose de la presentación de experiencias propias

ABSTRACT

Se planteó la validación de una prueba de logoaudiometría por vía ósea en pacientes con hípoacusias sensoriales y conductivas a fin de obtener una prueba que ayude en el diagnóstico y encamine a una adecuada rehabilitación. Las pruebas se realizaron en tres audiómetros de tres unidades médicas diferentes en tres grupos de pacientes, uno con perdida conductiva, otro sensorial y el tercero con audición normal. Se obtuvo un 97 por ciento de sensibilidad y 96.6 por ciento de especificidad de la prueba. Aunque son resultados preliminares, se concluye que la prueba es útil para la detección de reserva coclear en pacientes con pérdidas auditivas severas y profundas, sobre todo en pacientes con patología de oído medio

ABSTRACT

Se realizó un estudio transversal el 306 jóvenes con edades de 5 a 28 años, 62 deportistas y 244 no deportistas, sobre su capacidad funcional a finalidad de contrastar el factor psicopedagógico. Se observó que el estado de nutrición, edad cronológica, sexo y tiempo de ver televisión, son similares en ambos grupos, cuya diferencia fue en el desempeño físico y en el factor piscpopedagógico, el cual está conformado por el tiempo de aprendizaje, memoria a corto plazo, decodificación auditiva y concentración mental en favor de los que realizan actividad física formal.

ABSTRACT

En 79 niños de 7ny 8 años de edad se rastreó hipoacusia mediantea un audioscopio. El aparato consiste en un otoscopio tradicional de fibra óptica unido a un dispositivo para emitir sonidos de tono puro de 25 dB en un rango de frecuencias de 500 a 4.000 Hz. Los niños fueron estudiados inmediatamente después de una audiometría convencional. En 9 niños se encontrarom dficits de audición, 8 fueron correctamente identificados con el audioscopio. La proporción de falsos positivos puede ser muy alta, para reducirla se recomienda reiterar el procedimiento cuando el primer resultado sugiere un defecto. El equipo es de costo razonable, fácil de usar y más preciso que los métodos simples de rasteo semiológico
