Narrow Bands

The relationship between hearing level and loudness discomfort level (LDL) for narrow-band noise was evaluated in two groups of patients with sensorineural hearing loss. Group I had thresholds ranging from 25–60 dB SPL and Group II’s thresholds ranged from 65–100 dB SPL. LDLs were determined for narrow bands of noise centered at 500, 1000, 2000, and 4000 Hz. The LDLs for Group II were greater than those for Group I and the differences were statistically significant. It is speculated that one reason for others not finding differences as a function of hearing level may be the absence of severe to profound hearing loss in the test populations.

The Relationship

The present cross-sectional study set out to determine the nutritional status of infants aged 0–3 months with the WHO Multicentre Growth Reference (WHO-MGR) and examine the relationship between undernutrition and congenital or early-onset sensorineural hearing loss (CESHL) rarely reported for developing countries. The nutritional status of all infants attending community-based clinics for routine Bacille de Calmette-Guérin (BCG) immunisation from July 2005 to December 2006 was determined by weight-for-age, weight-for-length and BMI-for-age based on the WHO-MGR. Hearing loss status was determined by tympanometry, auditory brainstem response (ABR) and visual response audiometry after a two-stage screening with transient evoked otoacoustic emissions and automated ABR. The relationship between nutritional status and CESHL were explored after adjusting for potentially confounding maternal and infant characteristics using multivariable logistic regression analyses. Of the 3386 infants who completed the hearing evaluation protocol, seventy-one were confirmed with hearing loss (>30 dB hearing level). More than one-third (37·9 %) of all infants and over half (54·9 %) of those with CESHL were undernourished by at least one measure of growth. Stunting (35·3 %) was the most prevalent nutritional deficit in infants with CESHL. In the final logistic model, infants with any undernourished physical state were significantly likely to have CESHL (OR 1·67; 95 % CI 1·03, 2·77) and of a severe-to-profound degree (OR 3·92; 95 % CI 1·38, 11·17) compared with infants without any undernourishment. Prospective studies to establish the full spectrum of the relationship between undernutrition and CESHL, particularly in resource-poor countries, are therefore warranted.

<p class="abstract"><strong>Background:</strong> <span lang="EN-IN">The association between Hearing loss and diabetes, first mentioned by Jardao in 1857, had been under continuous research since then; giving both positive and negative results. This study aims to explore the relationship of hearing loss with type II DM and also to evaluate the impact of glycemic control over degree of hearing loss. </span></p><p class="abstract"><strong>Methods:</strong> <span lang="EN-IN">92 patients with type II DM were enrolled in this study, audiometrically evaluated and compared with equal number of age and sex matched non-diabetic controls. Apart from audiological tests, haematological tests like FBS, PPBS, HbA1c, serum creatinine and cholesterol were carried out to assess glycemic control.  </span></p><p class="abstract"><strong>Results:</strong> <span lang="EN-IN">It was observed that 31 (34%) of the diabetic patients had mild to moderate sensorineural hearing loss, while only 12 (13%) of the control group suffered from the same, which is statistically significant (p&lt;0.05). Among these 31 patients, 19 (61%) patients had uncontrolled diabetes (HbA1c &gt;8.5) and 12 (39%) had higher creatinine levels (&gt;2.5 mg/dl). Higher frequencies (4 and 8 kHz) were found to be affected more, both in case and control groups. Low stapedial reflex thresholds were observed in 14% patients of case group and 5.4% of the controls. Speech discrimination scores were not significantly different. Otoacoustic emission showed outer hair cell dysfunction in 85% cases and 66% controls. </span></p><p class="abstract"><strong>Conclusions:</strong> <span lang="EN-IN">There is a strong correlation between diabetes mellitus and hearing threshold levels especially at higher frequencies. Long duration and uncontrolled diabetes has more implications over hearing threshold. Since the pattern of hearing loss in diabetes and presbycusis is similar, it may be said that hearing level with ageing is significantly impaired earlier in diabetic patients as compared to general population.</span></p>

Aim: Sudden sensorineural hearing loss (SSNHL) involves acute unexplained hearing loss, nearly always one-sided of 30dB or greater over at least three contiguous audiometric frequencies. The aetiology of SSNHL is mostly unknown. According to the literature, the causes include vascular, microbial and autoimmune problems. There is still no agreed standard treatment. The aim of the paper was to evaluate the results of combined pharmacotherapy and hyperbaric oxygen therapy in patients with idiopathic sudden deafness. Material/Methods: The study was carried out on 40 patients with SSNHL. The patients were divided into two groups: group I – 24 patients treated with the combined pharmacotherapy and hyperbaric oxygen therapy and group II – 16 patients treated only pharmacologically. The patients from Group 1 were treated in the Centre of Hyperbaric Therapy CREATOR Ltd. in Lodz, Poland. Each patient underwent 15 sessions in a hyperbaric chamber. In all patients, the percentage of hearing loss for the selected frequencies was assessed before and after the therapy according to Sabine and Fowler. Results: The group of 40 patie nts aged from 33 to 77 years (mean 52.4) included 21 females and 19 males. Group I consisted of 24 patients, 11 females and 13 males, group II consisted of 16 patients, 10 females, and 6 males. After therapy, the mean hearing level in all patients improved by 27.14%, in Group I – by 34.34%, in Group II – by 16.3%. Conclusions: Early hyperbaric oxygen therapy combined with steroid therapy improves prognosis and shows good results in sudden hearing loss treatment.

A Prospective Study

Objective Saccule could be damaged in patients with idiopathic sudden sensorineural hearing loss (ISSHL) with vertigo and with high-frequency sensorineural hearing loss. Thus, the saccule might be deteriorated subclinically in ISSHL cases without vertigo. Therefore, we investigated saccular damage in ISSHL patients without vertigo through vestibular evoked myogenic potentials (VEMP). Study Design A prospective study. Subjects and Methods Fifty-two patients with ISSHL without vertigo were enrolled in the study. We identified VEMP in patients with ISSHL and analyzed the association of VEMP with initial hearing threshold, each threshold according to frequency, the type of audiogram, and hearing recovery. Results For cases with absent VEMP, we found significant differences between patients with 90 dB or more hearing loss and those with a hearing loss less than 55 dB with frequencies over 1000 Hz. Patients with profound hearing loss presented significantly high abnormal and absent VEMP than patients with audiograms of other types. Conclusion These findings suggest that the subclinical deterioration of the saccular neuroepithelium is associated with patients with ISSHL having profound hearing loss at the high frequency.

The Relationship

Objectives. Calprotectin, a protein released by neutrophils, has been used in many studies as a biomarker showing the presence of inflammation. In this study, it was aimed to investigate the relationship between serum calprotectin level and response to the treatment of idiopathic sudden sensorineural hearing loss (ISSHL).Methods. The present study is a prospective, cross-sectional historical cohort study. The study group consisted of 44 patients with ISSHL, and the control group consisted of 41 healthy volunteers without ear pathology. At the same time, patients in the study group were divided into three groups according to the response to ISSHL treatment (recovered, partially recovered, unrecovered). The relationship between the groups was statistically evaluated in terms of serum calprotectin levels.Results. The mean serum calprotectin value was 75.67±19.48 ng/mL in the study group and 50.24±29.14 ng/mL in the control group (<i>P</i>=0.001). Serum calprotectin value according to the severity of hearing loss in the mild, moderate and severe was 66.20±8.82, 70.35±16.77, and 91.23±19.73 ng/mL, respectively. Serum calprotectin value in the severe group was significantly higher compared to the moderate and mild groups (<i>P</i>=0.004, <i>P</i>=0.001, respectively). Serum calprotectin value according to the treatment response in the recovered, partially recovered and unrecovered groups was 63.36±11.54, 80.17±12.06, and 85.33±22.33 ng/mL, respectively. Serum calprotectin value in the recovered group was significantly lower compared to the partially recovered and unrecovered groups (<i>P</i>=0.002, <i>P</i>=0.001, respectively).Conclusion. Serum calprotectin value informs the clinician about both the severity of hearing loss and the response to treatment. Hence, serum calprotectin can be used as an important biomarker in ISSHL patients for the determination of the prognosis of disease.

INTRODUCTION Cochlear damage secondary to exposure to acoustic trauma is the consequence of the acoustic energy effects on the hearing cells in Korti's organ. OBJECTIVE The objective was to assess the correlation between the degree of sensorineural hearing loss and the type of audiogram registered in acoustic trauma exposed patients. METHOD We analyzed 262 audiograms of patients exposed to acoustic trauma in correlation to 146 audiograms of patients with cochlear damage and hearing loss not related to acoustic trauma. "A" group consisted of acoustic trauma cases, while "B" group incorporated cases with hearing loss secondary to cochlear ischaemia or degeneration. All audiograms were subdivided with regard to the mean hearing loss into three groups: mild (21-40 dB HL), moderate (41-60 dB HL) and severe (over 60 dB HL) hearing loss. Based on audiogram configuration five types of audiogram were defined: type 1 flat; type 2 hearing threshold slope at 2 kHz, type 3 hearing threshold slope at 4 kHz; type 4 hearing threshold notch at 2 kHz; type 5 notch at 4 kHz. RESULTS Mild hearing loss was recorded in 163 (62.2%) ears in the acoustic trauma group, while in 78 (29.8%) ears we established moderate hearing loss with the maximum threshold shift at frequencies ranging from 4 kHz to 8 kHz. The least frequent was profound hearing loss, obtained in 21 (8%) audiograms in the acoustic trauma group. Characteristic audiogram configurations in the acoustic trauma patient group were: type 1 (N=66; 25.2%), type 2 (N=71; 27.1%), and type 3 (N=68; 25.9%). Audiogram configurations were significanly different in the acoustic trauma group in comparison to the cochlear ischaemia group of patients (p=0.0005). CONCLUSION Cochlear damage concomitant to acoustic trauma could be assessed by the audiogram configuration. Preserved hearing acuity at low and mild frequency range indicates the limited damage to the hearing cells in Korti's organ in the apical cochlear turn.

Introduction Diabetes has become a global epidemic. Hearing loss has been long associated with diabetes. Brainstem Evoked Response Audiometry (BERA) is an objective, non-invasive, electro diagnostic test that not only evaluates the functional integrity of the subcortical auditory pathway but also provides topo-diagnosis of hearing loss. This study aims to identify the role BERA in detecting hearing loss early in diabetic patients.Materials and Methods In this study a total of 210 patients were taken and subjected to blood glucose levels followed by PTA were divided into two groups. Group I (n=105) consisted of diabetic patients with sensorineural hearing loss (SNHL) and Group II (n=105) had age and sex matched non-diabetics with SNHL. All the patients were evaluated with BERA.Results All the patients were subjected to Brain Stem Evoked Response Audiometry (BERA). Absolute latency of Wave I, III, V, I-III, III-V and I-V were assessed for both the ears. In both ear Absolute latency were significantly higher in diabetics as compared to non-diabetic patientsConclusion The findings of present study showed that the severity of hearing loss was significantly higher in diabetic patients as compared to non-diabetic controls. Level of glycemic control showed a possible link with severity of hearing loss.

Introduction: This study aimed to investigate the relationship between sudden sensorineural hearing loss, vestibular neuritis, and infection with COVID-19. Materials and Methods: In this study, a total of 56 Iranians (32 females and 24 males) with a Mean±SD age of 45.12±14 years were studied in Tehran City, Iran. Individuals diagnosed with Sudden Sensorineural Hearing Loss (SSNHL) or vestibular neuritis based on definitive diagnostic criteria were included in the study. The methodology comprised four sections of underlying Sudden Hearing Loss,, auditory and vestibular inspection, SARS-CoV-2 Reverse Transcription-Polymerase Chain Reaction (RT-PCR) test, and statistical analysis. Also, the videonystagmography test was used in participants with vertigo to diagnose vestibular neuritis. Pure tone audiometry confirmed SSNHL in some patients with a complaint of hearing loss. Furthermore, tuning fork, Rinne and Weber tests were also performed. Results: The results of SARS-CoV-2 RT-PCR in 56 subjects showed that eight subjects (22.2%) with vestibular neuritis and two with SSNHL (10%) had a positive RT-PCR test. The Chi- square and Fisher exact-tests with a 95% confidence interval revealed no statistically significant (P>0.05) relationship between COVID-19 infection and vestibular neuritis or SSNHL. Conclusion: The present study showed no statistically significant relationship between audiovestibular disorders and positive SARS-CoV-2 RT-PCR test. However, the possibility of this relationship cannot be ruled out, and there is a need for studies with larger sample sizes.

The significance of asymmetric sensorineural hearing loss (ASNHL) is due to a special approach to diagnosis, followed by the process of hearing aids and auditory rehabilitation. Currently, there is no standard audiometric criterion for determining the forms of asymmetry, which significantly affects the assessment of the prevalence of ASNHL. The study aimed to assess the prevalence and classification of ASNHL forms in the older age group using two methods of calculation: 1) the difference in the average hearing threshold at speech frequencies (in the range of 0,5–4 kHz) ≥15 dB was detected in 14,14% of cases; 2) the different degree of hearing loss, according to the International classification, in the right and left ear was 35,98%. In most cases, asymmetry was manifested by bilateral sensorineural hearing loss of varying severity, prevailing in the group of long-livers – 82,6%. Given the potentially high prevalence of asymmetry depending on the audiological criterion, the results of the work are a reason for further research in the development of a unified method for verifying a clinically significant form of ASNHL.
