Relation between continual evoked oto-acoustic emission(OAE) and spontaneous oto-acoustic emission.

The click-evoked oto-acoustic emission, c-EOAE, in preterm-born infants in the post conceptional age range between 30 and 68 weeks.

Click-evoked otoacoustic emissions (cEOAEs) were repeatedly recorded in an operational sample of 144 very low birth weight (VLBW) infants. A subgroup of 22 was composed of all those babies in which at least 4 recordings were successfully done. The mean birth weight of this group was 1040 g, and the mean duration of assisted ventilation was 17 days. The OAE-recordings were done in the post conce...

Impact of Usage of Personal Music Systems on Oto-Acoustic Emissions Among Medical Students

BACKGROUND Intact hearing is essential for medical students and physicians for communicating with patients and appreciating internal sounds with a stethoscope. With the increased use of (PMSs), they are exposed to high sound levels and are at a risk of developing hearing loss. The effect of long term personal music system (PMS) usage on auditory sensitivity has been well established. Our study ...

Branchio-oto-renal syndrome.

Branchio-oto-renal syndrome, a phenotype consisting of hearing loss, auricular malformations, branchial arch remnants, and renal anomalies is now recognized as one of the more common forms of autosomal dominant syndromic hearing impairment. Three loci known to be associated with the BOR phenotype have been identified and two genes that act in a regulatory network have been cloned, EYA1 and SIX1...

Branchio-oto-renal syndrome.

Branchio-oto-renal syndrome (Melnick-Fraser syndrome) is a rare autosomal dominant disorder characterized by syndromic association of branchial cysts or fistulae along with external, middle & inner ear malformations and renal anomalies. Authors are reporting a 19 year male patient, who presented with profound deafness & low set "lop-ear" with right sided preauricular pit. USG abdomen revealed a...
