Is there a relationship between hypercholesterolaemia and noise-induced XXXX ?

Many investigators who have analysed the possible correlation between @entity393 and high serum @entity165 levels have found that hearing appears to be influenced by high blood lipids. Noise, as is well known, also influences hearing, particularly at high frequencies. It increases serum @entity165 levels during short-term experiments. The present investigation addresses the question of a possibly increased ototraumatic influence by the combination of high serum @entity165 levels and occupational noise exposure. Seventy-eight 50-year-old @entity1 with high serum @entity165 levels from a WHO study were compared with 75 50-year-old @entity1 who were randomly selected from the same WHO material. Group mean audiograms showed that hearing was similar in both groups, with a moderate high frequency @entity393 having a configuration suggestive of a noise-induced @entity393 . Analysis of the individual histories and the pure-tone audiograms showed that noise was the most predominant factor influencing hearing at any specific frequency or combination of frequencies. There was a statistically significant tendency for the high- @entity165 group that had suffered the most noise exposure, to have a @entity2198 . There was also a tendency for the low- @entity165 group to have a high-frequency loss if they had been excessively exposed to occupational noise. No further correlations were found. The present results indicate a slightly increased risk of acquiring a high-frequency @entity1274 for @entity1 who work in noisy environments and have high serum @entity165 levels.
