Introduction: Mobile phones as fastest means of communication, indispensable for daily life globally. The widespread use has given rise to concerns about the potential health hazards of its electromagnetic fields (EMFs) on human health. The present study was conducted to investigate the adverse effects of mobile phone usage on auditory functions and to study the pattern of hearing threshold in mobile phone users. Objective: The objective of the study was to study the effect of mobile phone on average pure tone audiometry (PTA) threshold of the person and to study the changes in the pure tone threshold at high frequencies such as 2 kHz, 4 kHz, and 8 kHz among the students with prolonged exposure to mobile phones. Material and methods: A cross-sectional study was conducted among 200 medical and paramedical students who have been using mobile phones for one year or more, divided in two groups. Group A- less than one hour per day and GroupB- more than one hour per day. The effect of mobile phones on the PTA threshold in the exposed ear and the nonexposed ear was also assessed. Results: The study shows that there is a significant difference in average air conduction (AC) and bone conduction (BC) hearing threshold among the exposed and the nonexposed ears (P < 0.05) especially at high frequency. A significant rise of both AC and BC threshold in group B more than group A also noted in this study. Conclusion: The study conducted shows changes in the hearing threshold with mobile usage. The technology along with comfort also brings some hazards, hence to limit the duration of usage of mobile phones.

The Difference

Objective This study was performed to determine whether exposure to personal music players (PMPs) in the immediate morning prior to hearing testing confounds the association between mobile phone use and hearing thresholds of adolescents. Design In this cohort study of cognitive function in year 7 students (median age 13 years, range 11–14), information regarding the weekly use of mobile phones and the use of PMPs was assessed by a questionnaire. Pure-tone audiometry was used to establish hearing thresholds for all participants. Results Among a cohort of 317 adolescents (60.9% females), 130 were unexposed to PMP use while 33 were exposed to PMP use in the morning prior to hearing testing. No statistically significant difference in hearing threshold shifts was found between adolescents who were and were not exposed to PMP use prior to hearing testing. Likewise, the difference in the use of mobile phones according to the PMP use status was not statistically significant. Conclusion Exposure to PMPs prior to hearing testing did not introduce confounding in the present study of mobile phone use and hearing loss among adolescents.

Purpose: The purpose of this study was to investigate the effect of oral isotretinoin, a drug used in the treatment of acne vulgaris, on hearing function determined by serial audiology examinations. Methods: Forty patients with acne vulgaris were included in this study. Nine patients were excluded from the study because of inconsistent follow-up. The hearing of each participant was tested with pure tone audiometry and transient evoked autoacoustic emissions before and two and four weeks after treatment with isotretinoin (0.3-0.6 mg/kg/day) in the remaining 31 patients (62 ears). Results: The differences between the mean values of the pre-treatment and post-treatment pure tone hearing thresholds at 1000, 2000, 4000 and 6000 Hz frequencies were statistically significant (p < 0.05), but there was no significant difference between the pre-treatment and post-treatment values at 250 and 500 Hz frequencies (p > 0.05). The difference between the pre-treatment and post-treatment signal–noise ratio values of the transient evoked autoacoustic emissions was not significantly different (p > 0.05). Conclusion: Our results suggest that the use of isotretinoin may cause bilateral hearing threshold changes. Further animal and human studies are required to investigate and characterize isotretinoin-induced neurophysiological alterations in hearing.

Introduction: Noise-induced hearing loss is a significant, often unrecognized health problem among the military pilots. Advanced aircraft are powerful and more efficient but generate high noise causing noise-induced hearing loss (NIHL) among military pilots. Aim: To determine the prevalence of noise-induced hearing loss among pilots of the Bangladesh Air Force (BAF) and its association with aircraft type and flying hours. Methods: This cross-sectional study was carried out at Central Medical Board (CMB), Bangladesh Air Force (BAF) Dhaka from April 2017 to March 2018. The audiometry was done in the ENT department of CMB, BAF. Pure-tone audiometry was used to measure hearing thresholds and following pure tone frequencies were used for the test: 0.25, 0.5, 1, 2, 3, 4, 6 and 8 kHz. The association between flight hours and the development of noise-induced hearing loss was analyzed in the different age groups. Results: The study revealed NIHL in the aircrew was 16.5% with a higher prevalence among the helicopter pilots (18.6%) as compared with fighter (16.7%) and transport (11.5%) pilots. The left ear was affected in most of the cases than the right ear. Pilots of more than 40 years old and ≥1500 flying hours had a significantly higher hearing threshold compared with other categories. Conclusion: Exposure to noise in aircrew is unavoidable. By avoiding prolonged exposure to loud noise environments and utilization of personal hearing safety devices can prevent noise-induced hearing loss. JAFMC Bangladesh. Vol 15, No 1 (June) 2020: 12-15

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.

Abstract Objective The prolonged exposure to electromagnetic fields of mobile phones can damage the cochlear hair cells, which can be detected by otoacoustic emission (OAE). To know the effect of mobile phones on hearing, the young volunteers were subjected to prolonged mobile phone usage and changes in OAE were recorded. Materials and Methods Twenty-eight volunteers with normal hearing were made to talk one full hour continuously on the mobile phone. Distortion product otoacoustic emission (DPOAE) was measured prior to the usage of mobile phones and immediately after the use (post-exposure 1) and 24 hours after the use (post-exposure 2). The values were compared. Results Out of the 28 volunteers, 20 were females and 8 were males. Twenty-one volunteers preferred the right ear while using mobile phones, 7 preferred the left ear. There was no statistically significant difference between the baseline DPOAE values and values of post-exposure 1 and 2 when only the preferred ear was taken into consideration. When the preferred ear was compared with nonpreferred ear, a statistically significant difference was found only in the low frequencies between the pre-exposure and post-exposure 1 values. Conclusion This study shows there was no significant correlation between OAE and prolonged mobile phone exposure when the preferred ear was not considered.

<p class="abstract"><strong>Background:</strong> Hearing loss is common in patients with chronic renal failure. It is well known that chronic renal failure (CRF) causes different systemic and otorhinolaryngologic manifestations due to the accumulation of nitrogenous waste products. The aim of the study was to evaluate hearing threshold and the severity of hearing loss at different frequencies in patients of chronic renal failure (CRF), and to analyse the role of duration of disease on hearing threshold in patients of CRF.</p><p class="abstract"><strong>Methods:</strong> Fifty two patients of CRF were included in the study. Pure tone audiometry was done in all cases.</p><p class="abstract"><strong>Results:</strong> Majority of the patients were in 21 to 40 year age group (mean: out of 52 patients, 38 patients (73.07%) had sensorineural hearing loss and 14 patients (26.93%) had normal hearing. Majority of the patients with hearing loss had mild (44.73%) or moderate (42.11%) sensorineural hearing loss. On comparison of the mean hearing threshold Group II (duration of disease more than five years- 17 patients) showed a statistically significant difference (P&lt;0.05) in mean hearing threshold at 250 Hz.</p><p class="abstract"><strong>Conclusions:</strong> Hearing loss is present in majority of the patients of CRF. Most of the cases have mild to moderate sensorineural hearing loss. High frequency hearing loss in chronic renal failure is related to the duration of the disease, duration of haemodialysis’ and internal homeostasis, namely hyponatremia.</p>

New Perspective

Surgical treatment of otosclerosis with stapedotomy leads to the improvement of subjective and objective problems in patients with otosclerosis. A prospective study included patients who had been treated surgically at the Department for Ear, Nose and Throat in Novi Sad in the period from September 2006 to September 2007. On the basis of the appropriate diagnostic procedures, 33 patients were diagnosed with otosclerosis. Functional hearing was assessed before and after surgery by means of pure tone audiometry. The comparison of functional results before and after surgery revealed no changes in pure tone average of bone conduction threshold (average hearing threshold for hearing range), whereas pure tone average of air conduction and pure tone average of the gap showed statistically significant improvement. The results of this study demonstrated the applicability of stapedotomy as a method for successful management of otosclerosis. This way of examination offers a new perspective on patients? health, which should be defined as a physical, psychosocial and social well-being, and not only the absence of a disease itself.
