<p class="abstract"><strong>Background:</strong> There are no published studies that compared amplitude of stacked-Tone ABR and Chirp ABR in hearing impaired individuals with sensorineural hearing loss, which need to be investigated. Objective of the study was to know whether amplitude of standard chirp evoked ABR is same as tone burst evoked stacked ABR in individuals with normal hearing listeners and individuals with sensorineural hearing loss.</p><p class="abstract"><strong>Methods:</strong> Present hospital based cross sectional study was carried out at Malla Reddy Institute of Medical Sciences, from January 2016 to December 2016. Two groups of subjects were taken. Group I consisted of 20 ears (14 males and 6 females) with normal hearing. Group II consisted of 20 ears (11 females and 9 males) with cochlear hearing loss.  </p><p class="abstract"><strong>Results:</strong> Wave V Amplitude of stacked tone ABR was higher than Chirp stimuli evoked ABR wave V in both the groups. Amplitude of stacked tone ABR and chirp was smaller for individuals with sensorineural hearing loss than normal hearing. Between the 2 chirp stimuli, standard Chirp ABR amplitude was higher than modified Chirp in normal hearing listeners and individual with sensorineural hearing loss. For modified chirp in individuals with normal hearing and cochlear hearing loss. Latency obtained by standard chirp was longer compared to latency obtained by modified chirp, which is seen in both the groups.</p><p><strong>Conclusions:</strong> Chirp ABR may be opted over stacked tone ABR in neurological investigations due to its lesser variability in amplitude and shorter duration of testing. </p>

ABSTRACT Objective To assess the static and dynamic balance performance of students with normal hearing and with sensorineural hearing loss. Methods A cross-sectional study assessing 96 students, 48 with normal hearing and 48 with sensorineural hearing loss of both sexes, aged 7 and 18 years. To evaluate static balance, Romberg, Romberg-Barré and Fournier tests were used; and for the dynamic balance, we applied the Unterberger test. Results Hearing loss students showed more changes in static and dynamic balance as compared to normal hearing, in all tests used (p<0.001). The same difference was found when subjects were grouped by sex. For females, Romberg, Romberg-Barré, Fournier and Unterberger test p values were, respectively, p=0.004, p<0.001, p<0.001 and p=0.023; for males, the p values were p=0.009, p<0.001, p<0.001 and p=0.002, respectively. The same difference was observed when students were classified by age. For 7 to 10 years old students, the p values for Romberg, Romberg-Barré and Fournier tests were, respectively, p=0.007, p<0.001 and p=0.001; for those aged 11 and 14 years, the p values for Romberg, Romberg-Barré, Fournier and Unterberger tests were p=0.002, p<0.001, p<0.001 and p=0.015, respectively; and for those aged 15 and 18 years, the p values for Romberg-Barré, Fournier and Unterberger tests were, respectively, p=0.037, p<0.001 and p=0.037. Conclusion Hearing-loss students showed more changes in static and dynamic balance comparing to normal hearing of same sex and age groups.

Background and Aim: Sensorineural hearing loss (SNHL) is one of the complications in hemodialysis patients. Vascular access (VA) represents a lifeline for these patients affecting their life quality and clinical outcomes. Arterio­venous fistula is the gold standard of VAs with minor complications and better hemodialysis adequacy. There is no study investigating hearing differences in hemodialysis VAs. Hence, this study aimed to compare SNHL characteristics amongst hemodialysis VAs. Methods: This cross-sectional study conducted on 64 patients aged 18−60 years received regular hemodialysis in 2019. Demographic data and comorbid conditions were recorded based on patients’ case records and electronic databases. After a physical examination, otoscopy, tympa­nometry, and conventional audiometry, patients were divided into fistula (n = 26), permanent catheter (n = 36), and temporary catheter (n = 2) groups according to vascular access type. Results: Prevalence rate of SNHL was 63.89%, 50% and 50% in the permanent catheter, fistula and temporary catheter groups, respectively. Most patients had mild sloping-SNHL in the per­manent catheter and fistula groups as against moderate degree in the other group. There was no significant difference in hearing thresholds, deg­ree and audiogram shape among VA groups. No significant relation was found between age, sex, hemodialysis duration and disease duration with hearing loss in all groups (p > 0.05). Conclusion: More patients had SNHL in per­manent catheter group. Vascular access types, longer duration of hemodialysis and disease dur­ation do not seem to be associated with SNHL. However, further investigation is needed to cla­rify the relationship. Keywords: Sensorineural hearing loss; vascular access; chronic renal failure; hemodialysis

Objectives: To determine the frequency of sensorineural hearing loss (SNHL) in children with bacterial meningitis. Study Design: Cross Sectional study. Setting: Department of Paediatric Medicine Nishtar Hospital, Multan. Period: October 2019 to March 2020. Material & Methods: The study was conducted after permission from ethical committee. A total of 151 patients admitted with bacterial meningitis were enrolled. Apart from the presenting complaints, necessary information like the age and gender were noted. Examination of the child was done to assess the condition of child. Brainstem evoked response audiometry (BERA) test was performed before discharge of the patient from the hospital. The outcome variable that is SNHL in bacterial meningitis assessed by BERA test was noted in a specifically designed Performa. Results: Out of total of 151 patients, males were 83 (55%) while females 68 (45%). Overall mean age was 11.85+6.12 months. SNHL was found in 26 (17.2%) children. There was no significant effect of age or gender on the frequencies of SNHL. Conclusion: SNHL is a frequently encountered complication in our population of children with bacterial meningitis. SNHL should be carefully sought out and properly diagnosed in all the patients presenting with bacterial meningitis.

Obesity is an increase in total body fat, that is if found to be overweight > 20% in men and 25% in women due to fat. Increased obesity cannot beseparated from lifestyle, such as decreased physical activity.    One complication   that   can   be   caused   by   obesity   is   hearing   loss, especiallysensorineural hearing loss caused by microangiopathic abnormalities, especially in the inner ear. But the relationship of events between obesity withhearing loss is still often a debate, because there is no definite consensus. The purpose of this research determine the relationship of obesity with sensorineural hearing loss. This research is an analytic study by obtaining cross-sectional study, with data obtained from the assessment of bodyweight and height to see the status of the mass index, physical examination of the ear, and audiometric examination. Data analysis techniques using the chi square test statistics. Research result obtained relationship between obesity with sensorineural hearing loss as much as 49.09% and the highest degree of hearing loss is mild degrees as much as 27.07%. Research conclusions there is a significant relationship between obesity with sensorineural hearing loss.

Background: To know the prevalence of sensorineural hearing loss among chronic suppurative otitis media patients To study the correlation between duration and clinical findings of CSOM with the degree of hearing loss. Materials and Methods Hospital based cross sectional study of patients aged between 10 to 45years with unilateral chronic suppurative otitis media attending Tirumala Super speciality Hospital, Kadapa from December 2015 to November 2017 with sample size of 100 cases were taken. Results: Out of the 100 cases, 10 patients were having sensorineural hearing loss. Thus the percentage is 10%. Out of the 10 cases of sensorineural hearing loss, no cases with sensorineural hearing loss between 10-15yr and 16-20yr age group. 2 were between in the age group of 26-30yr, 31-35yr and 36-40yr age group and 4 patients were in the age group of 41-45yr. Out of 100 patients 52 were males and 48 were females. Out of 10 patients with sensorineural hearing loss 6 were males and 4 were females. The duration of ear discharge ranged from 3 months to more than 15 years. Among the 100 patients studied 64 had ear discharge from 3months to 5yr. 16 had ear discharge from 6-10yr, 11 had ear discharge from 11-15yr and 9 had ear discharge of more than 15years. Conclusion: Our study shows presence of significant (10%) sensorineural hearing loss in patients with chronic suppurative otitis media. Duration of ear discharge correlates well with sensorineural hearing loss. No significant correlation between sex and sensorineural hearing loss. Keywords: Chronic suppurative otitis media, tubotympanic disease, sensorineural hearing loss.
