Audiometric profile in patients with chronic renal failure.

Abstract
OBJECTIVES:
To determine the occurrence of hearing loss and to establish audiometric profiles and patterns of hearing impairment in patients with chronic renal failure (CRF).
METHODS:
A retrospective study examined the relationship between the different stages of CRF and corresponding audiologic findings in those patients. Twenty-three subjects (46 ears) in the age range of 25 to 60 years were included in the study. These subjects were arranged into groups ranging from the second to fifth stages of CRF. Audiologic assessment in each subject was performed using a battery of tests, which included pure-tone audiometry, transient otoacoustic emission (TOAE), distortion product otoacoustic emission, and brainstem evoked response audiometry (BERA).
RESULTS:
Significant differences in the degree of hearing loss were observed among patients with different stages of CRF. It was noted that almost all (95.65%) patients with CRF did not pass the TOAEs. It was important to notice that none of the patients with CRF showed findings on BERA that pointed to retrocochlear involvement. Thus, the present study found that most patients (65.21%) had a cochlear pathology.
CONCLUSIONS:
We observed that (a) there is a high incidence of hearing loss among patients with CRF; (b) the methods of treatment (hemodialysis and conservative treatment) may not influence the impact of the disease on hearing; (c) levels of serum electrolytes and biochemical constituents of blood do not seem to correctly reflect the audiologic status of a CRF patient; and (d) hearing loss in patients with CRF has a distinct audiologic pattern. Given that CRF involves hearing loss, routine audiologic assessment in patients with this condition is essential.

Objectives: Treatment of tinnitus is not ‘absolute’ in terms of its approach through a single therapy model. The more recent modes of treatment focus on attenuating somatic perception and on synchronizing the emotional component of tinnitus with more ‘positive’ physiological events in the body, so that the person does not correlate the presence of tinnitus with annoyance and a source of disturbance. Both these goals are possible with neurophysiological ‘habituation’ at proper synapses across the auditory pathway. The present study has been conducted to observe the effects of Bhramari Pranayama (BP) on both the physical and emotional aspects of tinnitus. Bhramari Pranayama is a ‘Yogic’ technique that involves the combination of a relaxing posture and a process of producing sub-tinnitus level humming sound during exhalation along with simultaneous pressing of the closed eyelids. Study Design: A group of patients with tinnitus was administered BP as a therapy. Three other groups of similar patients were given Ginkgo biloba, Masking therapy and a combination of all the above-mentioned modalities, respectively, as treatment for tinnitus. The outcome of the study was determined by analysing the pre- and post-therapeutic values measured for parameters such as: 1) Loudness; 2) THI score; and 3) Anxiety and Depression scale. Results: Demonstrated that BP as well as all the other modalities of treatment significantly reduced the post-therapeutic scores in all the parameters, in all the groups. Conclusion: We concluded that BP significantly reduced the irritability, depression and the anxiety associated with tinnitus. It relieved the symptoms in tinnitus possibly by 1) acting as source of self-generated sound; 2) inducing parasympathetic predominance in the neural milieu; and 3) by acting as a relaxation technique. BP may serve as a cost effective, frequently applicable adjuvant therapy for tinnitus that probably acts through neuromodulating principles.
