Pure tone audiometry and otoacoustic emissions for the assessment of hearing loss in diabetic patients

2013-01-01 Agarwal, A. C., Pujary, K Balakrishnan, R Nayak, D. R Hasan, F

Context: Evaluation of hearing loss with diabetic control. Aims: The aim of this study was to profile the audiologic findings of diabetic patients by assessing the degree of hearing loss and the presence/absence of otoacoustic emissions (OAEs); to correlate the factors, namely, age, gender, glycemic status, and duration of diabetes mellitus with hearing loss. Settings and Design: The study was done at a tertiary care hospital and a cross-sectional study design was employed. Materials and Methods: Forty known diabetic patients who satisfied the selection criteria and consented were included in the study. Three tests were carried out, namely, pure tone audiometry, immittance audiometry, and OAEs. Statistical Analysis Used: Statistical analysis was performed using the Statistical Package for Social Sciences (SPSS) version 11.5. For the current study, median, interquartile range (IQR), frequency, and percentage were considered. Results: Majority of the patients had bilateral sensorineural hearing loss ranging in severity from minimal to mild degree. Median pure tone average (PTA) values were less in patients with good glycemic status as compared to those with poor glycemic status. OAEs were absent in 30% of the subjects. Age had a contributing effect on raising the hearing threshold but gender and duration of diabetes did not show such an effect. Conclusion: Diabetic patients are at an increased risk of developing sensorineural hearing loss. Indian Journal of Otology,19(1), 13. 2013

Rhyme and Phonemic Awareness Skills in Kannada Speaking Children with Cerebral Palsy.

Selvakumar, A. M. R., John, S B Rajashekhar

Rhyme and phoneme awareness are skills that are essential for learning to read and spell. Their significance has been well established in alphabetic languages. Few studies have ventured to understand these skills in an alpha- syllabary language such as Kannada, where their significance has been debated. However, research related to these skills in childhood conditions like cerebral palsy is scarce. The present study aimed to understand the rhyme and phonemic awareness skills through the tasks of rhyme recognition, phoneme stripping and phoneme oddity for non-words using Metaphonological Skills Test (Prema, 1997). The participants were Kannada speaking children with cerebral palsy (n=12) and language-age (> 8 years) matched, typically developing peers (n=30). The results showed a significant difference between groups for phoneme stripping alone. This implies a lag in the development of phoneme awareness skills in children with cerebral palsy (CWCP). This necessitates early metaphonological instruction and inclusion in the educational curriculum of CWCP. Language in India, 15(1), 21-35. 2015

Syllable Awareness in Kannada Speaking Children with Cerebral Palsy.

Selvakumar, A. M. R., John, S. B Rajashekhar

Syllable awareness is a metaphonological skill that is acquired by children before acquisition of phoneme awareness skills. Its importance has been documented in alphabetic languages where it functions as a predictor of later reading success. However, it has been less researched in alphasyllabary languages with dearth of knowledge in childhood disorders like cerebral palsy. In the present study, the skills of syllable stripping and syllable oddity for words and non-words were studied using the Metaphonological Skills Test (Prema, 1997) in Kannada speaking children with cerebral palsy (n=12) and language-age (> 8 years) matched with typically developing peers (n=30). The findings revealed that performance for syllable stripping and syllable oddity for words was on par for both groups. However, children with cerebral palsy (CWCP) performed poorly on syllable oddity for non-words proving that the ability to engage in overt articulation has an indirect influence on their performance.

Normative for Motor Speech Profile in Kannada-Speaking Adults.

John, J John, S B Rajashekhar

The primary purpose of this study was to establish normative for 18 parameters of Motor Speech Profile (MSP; Computerized Speech Lab; KayPENTAX, Lincoln Park, NJ) in Indian population, specifically for Kannada-speaking adults across age and gender. Study Design: Cross-sectional study. Method: Native Kannada speakers (n = 300) were divided into three age groups (20–40, 41–50, and 51–60 years) with 50 males and 50 females in each group. The obtained data are reported across age and gender for the parameters of diadochokinetic rate, second formant transition, and voice and tremor characteristics of MSP software. Results: Across gender, a statistically significant difference (P < 0.05) was seen for seven parameters; whereas across age, a statistically significant variation was seen for nine parameters in the age group of 51–60 years than other groups (20–40 and 41–50 years). Conclusion: Establishment of the normative is essential for the effective use of acoustic analysis as an objective tool. The findings of the present study serve as a norm-based reference forMSP software in Indian population, aged between 20 and 60 years. Journal of Voice, 28(1), 7-13. 2014
