Sir,I read the recent publication on diabetes mellitus and auditory brainstem responses with a great interest.[1] Gupta et al, concluded that “BERA is a simple, noninvasive procedure to detect early impairment of acoustic nerve, and CNS pathways, even in the absence of specific symptoms.[1]” I would like to make a discussion on this work. I agree that there can be the aberration of the auditory system in DM. However, the suggestion to use the BERA as a possible screening tool has to be systematically evaluated. The first question is on the cost effectiveness of this technique. Before, possible implementation of routine usage of BERA for general diabeticpatients, this point has to be clarified.
