Objectives: Our aim was to validate the “Wulira App” a mHealth application against gold standard audiometry as a pragmatic audiometry solution for under-served and vulnerable groups of patients at risk of hearing loss. The specific objectives were as follows: To compare hearing thresholds determined using the Wulira app to standard pure tone audiometry among patients on MDR-TB treatment. To determine the correlation between the measured hearing loss with the Wulira app and standard audiometry with patient reported hearing loss. To determine the proportion of patients on MDR-TB treatment that experience hearing loss? Materials and Methods: We consecutively recruited patients ≥18 years old and receiving kanamycin in their treatment regimen between February and June 2019 for this study. Clinical and demographic data were obtained from each participant and documented in a secure database. Participants had hearing assessment performed once at enrolment with paired standard audiometry and the Wulira mobile phone app in a soundproof room. Results: A total of 120 MDR-TB patients with a mean age of 34.0 (±9.6) years were recruited for this study and 69 (57.5%) were male. When compared to pure tone audiometry, the Wulira app was able to correctly detect 91.4% hearing loss in right ear and 88.4% in the left ear. The specificity of the Wulira app was equally high, reaching 93.2% in the right ear and 91.5% in the left ear. Conclusion: The Wulira app may be a useful alternative home-based tool for hearing assessment in MDR-TB patients, essentially for early detection of hearing loss following commencement of second-line injectable drugs.

AbstractObjective:This paper describes the first reported case of progressive sensorineural hearing loss caused by azathioprine, which was reversed on stoppage of the drug.Case report:A female patient with previously normal hearing presented with progressive sensorineural hearing loss after being started on azathioprine. Otological and neurological examination findings were unremarkable. After stopping the drug, the patient reported an improvement in hearing, which was confirmed on pure tone audiometry.Conclusion:This previously unreported side effect of azathioprine is highlighted in order to increase clinical awareness. Early recognition of this adverse effect is important to minimise the possibility of permanent sensorineural hearing loss.

<p class="abstract"><strong><span lang="EN-US">Background:</span></strong>Hearing loss is an invisible injury that has been viewed as an acceptable by-product of military service. It is imperative to detect hearing loss at early stage to take immediate remedial measures. In Indian armed forces the current method of assessment of hearing is primarily by Free Field Hearing which is obsolete and has numerous shortcomings. We contucted a study using free iOS application to detect hearing loss. The objectives of the study were to investigate the validity and reproducibility of app based hearing assement and free field hearing with clinical pure tone audiometer as gold standard. It is cross sectional intra-subject comparative study</p><p class="abstract"><strong><span lang="EN-US">Methods:</span></strong>The study was conducted at CHAF where 200 patients were accrued. Hearing assessment was carried out by Pure Tone Audiometry (PTA) which is gold standard. Thereafter these patients were subjected to hearing assessment by using windows application “freehearingtestsoftware.com” and by free field hearing (FFH).  </p><p class="abstract"><strong><span lang="EN-US">Results:</span></strong>Hearing assessment by FFH and hearing check app was compared with PTA. Hearing check app was found to be more sensitive than FFH (98% and 73%). Both modalities had high specificity (95% and 99%). The test retest reproducibility measured with Pearson correlation coefficient was high (0.99) with hearing check app.</p><p class="abstract"><strong><span lang="EN-US">Conclusions:</span></strong>Smart phone application like Hearing check app is a cheap and effective way to assess hearing with reasonable accuracy. It’s high sensitivity and high test retest reproducibility makes it an ideal tool for screening and early detection of hearing loss replacing out-dated free field hearing.</p><p class="abstract"><span lang="EN-US"> </span></p>

Objective: To assess the hearing loss among the subjects using excessive mobile phone. Methodology: 50 subjects were entered for this study with age ranging from 20 to 40 years using mobile phone for more than 5 years. 25 subjects who used mobile phone for less than (<) 60 min /day formed one group, while 25 subjects who used cell phone for more than (>) 60 min /day formed the second group. The hearing levels of all the subjects were tested using Pure Tone Audiometry (PTA). Duration of mobile phone usage was assessed by questionnaires. Results: There was a significant increase (p-value .00006) in the hearing thresholds at all frequencies in air conduction and bone conduction in right ear in test group compared with the control group. Similar result was found in the left ear except for bone conduction at frequency 4 and 6 (kilo hertz) kHz. Excessive use of mobile phone caused Sensory neural hearing loss and the prevalence was 84% in group who used mobile phone for > 60 min / day and 20% in group who used for < 60 min / day. Conclusion: Excessive use of mobile phone may cause increase in pure tone threshold associated with the duration of usage. The use for more than 5 years with more than 60 minutes daily can produce harmful effects on human hearing.

<p class="abstract"><strong>Background:</strong> With the advent of new smart phones every day, health hazard related to it is also increasing. The usage of mobile phones has become a domineering activity of the students. Such usage have been documented to cause many health hazards like hearing loss, the mobile phone electromagnetic radiation has other potential risks like vehicular accidents, headache, and sleep disturbances, thermal effects and alteration of blood brain barrier. The objective of the study was to assess the hearing loss with pure tone audiometry due to chronic mobile phone usage among medical college students in a tertiary care hospital.</p><p class="abstract"><strong>Methods:</strong> This was a cross sectional study conducted among the medical students from June 2018 to December 2018, with the sample size of 129. The participants were interviewed using pretested, validated questionnaire followed the participants were subjected to pure tone audiometry.  </p><p class="abstract"><strong>Results:</strong> Among the 129 participants, the majority of the study participants (58.1%) were females. The median age of the participants was 20 and almost 42.7% of the participants used in ear media while using the phone. 10.9% and 19.4% showed symptoms of tinnitus and hard of hearing respectively. On testing the participants with pure tone audiometry, around 9.3% had mild hearing loss and 3.9% had moderate hearing loss.</p><p class="abstract"><strong>Conclusions:</strong> The health hazard caused by the mobile phone usage may not be evident for many years. The students are exposed to smart phones frequently and hence periodic screening and health education regarding the harm of using mobile phones for longer duration should be made imperative.</p>

AbstractObjectivesSodium bromate is a strong oxidant, and bromate intoxication can cause irreversible severe-to-profound sensorineural hearing loss. This paper reports the first case in the English literature of bromate-induced hearing loss with hearing recovery measured by formal audiological assessment.Case reportA 72-year-old woman was admitted to hospital with complaints of profound hearing loss, nausea, diarrhoea and anuria after bromate ingestion in a suicide attempt. On admission, pure tone audiometry and auditory brainstem responses showed profound bilateral deafness. Under the diagnosis of bromate-induced acute renal failure and sensorineural hearing loss, continuous haemodiafiltration was performed. When dialysis was discontinued, pure tone audiometry and auditory brainstem responses showed partial threshold recovery from profound deafness.ConclusionSevere-to-profound sensorineural hearing loss is a common symptom of bromate intoxication. Bromate-induced hearing loss may be partially treated, and early application of continuous haemodiafiltration might be useful as a treatment for this intractable condition.

Objective: To evaluate cochlear functioning in patients (18 - 45 years old) with varying stages of chronic kidney disease (CKD). Using purposive sampling, 50 participants, 10 in each of the 5 stages of CKD, were selected and underwent pure tone audiometric testing and distortion product otoacoustic emissions (DPOAEs).Results: Significant differences (p<0.05) were found between pure tone audiometry and DPOAEs in detecting early cochlear dysfunction in the high-frequency range in stages 3 (6 000/5 000 Hz; p=0.00), 4 (6 000/5 000 Hz; p<0.03) and 5 (4 000/3 333 Hz; p<0.01, 8 000/6 667 Hz:p<0.05) with DPOAEs being more sensitive in identifying early cochlear dysfunction. Patients in stages 1 and 2 presented with normal puretone thresholds and DPOAEs, suggesting that cochlear functioning in these patients was normal. Early cochlear dysfunction, thereby indicating a subclinical hearing loss, was identified in stages 3, 4 and 5 by DPOAE testing. In addition, blood test results, drug intake and concomitant conditions were recorded and analysed which suggested a relationship between reduced cochlear functioning and increased electrolyte levels, treatment regimens and concomitant conditions.Conclusion: Participants in the later stages of CKD presented with early cochlear dysfunction, presenting with subclinical hearing loss. It was postulated that this subclinical hearing loss resulted from a combination of electrolytic, urea and creatinine imbalances, together with concomitant medical conditions and ototoxic drug intake. It was concluded that audiological monitoring be included in the management of patients with CKD and that DPOAEs be introduced as part of the test battery to monitor cochlear function in patients with varying degrees of CKD.

Chronic suppurative otitis media is one of the common otological conditions in India for which patients seek advice from an otorhinolaryngologist. Chronic suppurative otitis media is recurrent and progressive disease which is characterized with tympanic membrane perforation and suppurative discharge. Pure tone audiometry is the most common test used to evaluate auditory sensitivity. Since hearing loss is a common complication of chronic suppurative otitis media, we designed this study to evaluate preoperative pure tone audiometry findings in patients with chronic suppurative otitis media and its correlation with the intra-operative findings. <strong>Aims and Objectives:</strong> 1] To assess the intra-operative findings in patients with chronic suppurative otitis media. 2] To evaluate the correlation between the preoperative pure tone audiometry findings and intra-operative findings in patients with chronic suppurative otitis media. 3] To assess the type of hearing loss and degree of hearing loss in patients with chronic suppurative otitis media. <strong>Materials and Methods:</strong> This is an Observational study carried over a period of 3 years from August 2011 to August 2013. Total number of patients included in this study was 100. <strong>Result:</strong> Out of 100 patients studied 69 % of patients had Tubo-Tympanic type of CSOM, 31 % of patients had Attico-antral type of CSOM. In patients of Safe CSOM; Central perforation was seen in maximum cases 46.4 %, anterior central perforations was seen in 8.7 % cases, posterior central perforations seen in 20.2 % cases, and subtotal perforations seen in 24.63 % cases. In patients of Unsafe CSOM posterosuperior cholesteatoma was seen in maximum cases 67.74 %, and attic cholesteatoma was seen in 32.2 % cases. In safe CSOM patients all ossicles were intact and mobile whereas in unsafe CSOM patients only 4 patients had intact ossicular chain, while maximum patients had ossicular defect. <strong>Conclusion:</strong> Hearing loss depends on size of perforation. Hearing loss increases as the size of perforation increases. Average air conduction threshold and air bone gap did not differ significantly between various groups of ossicular defect. This shows us that neither air conduction nor air bone gap are reliable parameters on basis of which we can predict ossicular status preoperatively.

Objectives: To compare assessment of hearing by PTA and status of tympanic membrane by oto-endoscope, pre-operative and post-operative tympanoplasty. Study Design: Retrospective/ Comparative study. Setting: Two different hospitals in Karachi. 1-Social Security Landhi Hospital Karachi. 2- Al-Tibri medical College & Hospital, Old Thana, Malir, Karachi. Period: July 2017 to June 2018. Material & Methods: 76 patients were included for this study with both genders who had dry tympanic membrane perforations. Age ranges between 18 to 40 years. Made two groups A (pre-operative and B (post-operative). In group-A, examined tympanic membrane perforations. 45 patients had small size (25%) perforations, 15 medium size (50%) and 16 subtotal (75%). Hearing assessment done by Pure tone Audiometry (PTA). After 1. 2 and 3 months post-tympanoplasty, examined grafted tympanic membrane and compared pre-operated status of tympanic membrane with post-operated status of tympanic membrane. PTA done after 3 months and compared it with pre-operated PTA. Results: Examination of tympanic membrane before tympanoplasty performed, perforations noted in all patients with different sizes in their tympanic membrane. PTA (pure tone audiometry) advised before tympanoplasty to all patients. Weber test performed on 1st post-operated day, it was lateralized towards operated ear which indicate the safety of inner ear. Post-operated 1, 2 and 3 months examined tympanic membrane with oto-endoscope. Intact grafted tympanic membrane seen in 70 patients after 1 months. After 2 months 72 patients had intact grafted tympanic membrane and after 3 months 73 patients out of 76 patients had intact grafted tympanic membrane. PTA also advised after 3 months of tympanoplasty and compared it with pre-operated pure tone audiometry (PTA). Air conduction (AC) decreased 15.39dB after tympanoplasty. AB-gap reduction 13.95dB seen in 73 patients which showed hearing improvement. P value is < 0.001 significant. Conclusion: Tympanoplasty is a good and safe procedure for hearing improvement by reduction of AB-gap as well as provide protection of middle ear mucosa from infections due to closure of perforations of tympanic membranes.
