cation outcomes due to the age at CI fitting was assessed at regular intervals in children starting at 2, 3, 4 and 5 years of age.

"Research clearly demonstrated for the first time the critical importance of very early CI implantation on communication outcomes," said study author Liliana Colletti, PhD. "The age at fitting CI ranged from 2 to 48 months, and the degree of hearing loss was bilateral and profound in all children."

The study required a participant pool that included infants, toddlers and older children fitted at different ages and the assistance of specialized anesthesiological teams. Limitations of longitudinal studies include selection biases. Age at CI implantation was a significant factor in all outcome measures contributing significantly to speech perception, speech production, and language outcomes. Intra, immediate, post-operative and long term complications showed no statistical difference among groups.


Plenary Session Presentation Heavy Metals Exposure and Hearing Loss in US Adolescents

Chicago, IL Blood lead levels well below the current recommended safe limit are associated with substantially increased odds of high frequency hearing loss.

Researchers evaluated the cross-sectional associations between blood lead, blood mercury, urine cadmium, and urine arsenic and audiometrically determined hearing loss in participants aged 12 to 19 years in the 2005-2006 National Health and Nutrition Examination Survey (NHANES). There were 1,632 individuals available for analysis of blood lead and mercury, and 560 for urine cadmium and urine arsenic. Multivariate logistic regression was used to calculate adjusted odds ratios (OR) and 95% confidence intervals (CI).

"Research showed, while arsenic, mercury and cadmium did not appear to have an overall association, blood lead levels above 2 mic
