[Otoacoustic emissions screening as early identification of hearing loss in newborns]. / Otoemisiones acústicas como prueba de cribado para la detección precoz de la hipoacusia en recién nacidos.

The aim of this study was to examine the results of transient evoked otoacoustic emissions (TEOAE) as screening test for hearing impairment in newborn infants. We examined 9.951 of 11.405 infants born in our city from January 1st, 1995, to December 31st, 1998. A TEOAE test was performed prior to discharge and repeated one week later in cases who failed the first TEOAE. In case of suspected hearing loss auditory brainstem response (ABR) was performed 3 months later. Hearing loss was defined as ABR threshold > 20 dB. 157 infants (1.5%) were identified with hearing loss. Screening with TEOAE was sufficiently sensitive in identification of congenital hearing impairment and the efficacy increased with the experience.

Otoemisiones acústicas como prueba de cribado para la detección precoz de la hipoacusia en recién nacidos / Otoacoustic emissions screening in early identification of hearing loss in newborn

El objetivo de este trabajo fue presentar los resultados de las otoemisiones acústicas evocadas transitorias (OEAT) al utilizarlas como test de cribaje para la detección de hipoacusias en recién nacidos. Nosotros estudiamos 9.951 de los 11.405 recién nacidos en nuestra ciudad, desde el 1 de enero de 1995 al 31 de diciembre de 1998. Se realizaron OEAT a los neonatos antes del alta hospitalaria y se les repitieron a la semana si fallaron las primeras OEAT. Aquellos niños con sospecha de hipoacusia fueron sometidos a potenciales evocados auditivos del tronco cerebral (PEATC) a los 3 meses. Se consideró hipoacusia cuando no se detectó en los PEATC onda V a 20 dB. Ciento cincuenta y siete niños (1,5 por ciento) tuvieron déficit auditivo. El cribaje con OEAT fue suficientemente sensible en la identificación de hipoacusias congénitas, aumentando la eficacia de la prueba conforme mejoraba la experiencia del explorador (AU)

El problema del seguimiento en un programa de detección precoz de sordera / The problem with monitoring in a deafness early detection program

Con la llegada de los avances tecnológicos a la valoración de la audición en los recién nacidos, ha sido posible la implantación del cribaje auditivo universal. Pero uno de los mayores problemas de estos programas es el pobre seguimiento de los niños que fallan el test inicial del cribado. Nosotros apreciamos una ventaja si se realiza el test y retest a los neonatos antes de que abandonen el hospital (AU)

[Primary carcinoma of the trachea. Report of 2 cases]. / Carcinoma primitivo de tráquea. A propósito de dos casos.

Tumours of the trachea remain relatively rare, the incidence of tracheal carcinomata is less than 0.1 per cent. Tumours of the larynx and lungs are, respectively, 75 and 180 times more frequent than malignant lesions of windpipe. Two patients with primary tracheal tumours were evaluated. The present study was undertaken in order to describe and analyse the most pertinent clinical and pathologic features of tracheal carcinomas as they relate to treatment and prognosis.

[Early detection of hearing loss in neonates by using transient evoked otoacoustic emissions]. / Detección precoz de hipoacusia en recién nacidos mediante otoemisiones acústicas evocadas transitorias.

OBJECTIVE: A precocious diagnosis of infantile deafness is essential to avoid its implications in the family and the social and employment future of those that suffer from them. The discovery of new tests that can be used for auditory screening, such as otoacoustic emission, has opened new perspectives in this field. PATIENTS AND METHODS: Universal screening was performed including neonates born in our area. We studied 7,153 children (296 with indicators of risk) born between 1995 and 1997. Our protocol was based on transient evoked otoacoustic emissions as the screening method and brainstem auditory evoked potentials as the diagnostic procedure. RESULTS: Two out of 1000 ears studied presented serious/deep deafness and 1.39 per 100 had some type of hearing loss. The incidence of pathology was higher among ears of children with risk factors: 1.8 per 100 had serious/deep deafness and 7.59 per 100 some type of hearing loss. CONCLUSIONS: Transient evoked otoacoustic emission is an effective method when used in infantile auditory screening, since it is objective, bloodless and quick. Its correlation with auditory evoked potentials is very high, which proves their reliability. The best moment to perform this test (OAE) is when the discharge from the hospital is certified. We believe that universal screening is necessary, although a much higher incidence of deafness is encountered among children with risk factors. The establishment of programs for the precocious detection of infantile deafness should not be delayed.

[Laryngeal paraganglioma]. / Paraganglioma laríngeo.

A case of laryngeal paraganglioma in a 65-year-old male was treated by supraglotic laryngectomy. This controversial tumor is analyzed and guidelines are given for its clinical and histological (immunohistochemical) diagnosis and treatment.
