Do thyroid cancer patients with basal undetectable Tg measured by current immunoassays require rhTSH testing?
Low risk patients with undetectable basal Tg measured with current commercially available immunoassays should be followed with at least one rhTSH stimulated Tg and neck US because of the insufficient predictive value for recurrence/persistent disease of basal Tg.
For these subjects, the sound sensation created by steady electric stimulation on the most-apical electrode was neither a white noise nor a pure tone, but a complex signal with a progressive increase in the spacing between the frequency components in 3 out of 5 subjects. Knowing whether the inharmonic nature of the sound was related to the fact that the non-implanted ear was impaired has to be explored in single-sided deafened patients with a contralateral CI. These results may be used in the future to better understand peripheral and central auditory processing in relation to cochlear implants.
