Introduction: As one of the preferred modes of land transportation, the frequency of train services was very high. One of the negative impacts arising from train activity was noise. The high noise intensity of the train causes hearing loss. Method: This study aims to analyze the differences in the incidence of hearing loss in 2 groups of residents in Turirejo Lawang Malang. This research used the observational method and the data were analyzed descriptive qualitative. A total of 20 people were selected as respondents by purposive sampling. Noise intensity was measured by Sound Level Meter and audiometric measurements were examined at SIMA Malang Laboratory. Result and Discussion: The prevalence of sensorineural hearing loss was more common in residents whose homes at 3-7 m away from the railroad tracks. In addition, residents who lived at least 15 years at a distance of 3-7 m also experienced more hearing loss. One cause of hearing loss is due to exposure to high noise and for a long time and will damage the hair cells in the cochlea, causing hearing loss. If noise exposure continues and for a long period of time damage to hair cells will be permanent and cannot return to normal. Conclusion: There needs to be a policy from the government in determining the minimum limit of the distance of the house to the railroad tracks. In addition, it is necessary to install a barrier near people’s homes to reduce noise.

Missense Variation

Purpose: Usher syndrome (USH) is an autosomal recessive disorder characterized by congenital sensorineural hearing impairment and retinitis pigmentosa. Classification distinguishes three clinical types of which type I (USH1) is the most severe, with vestibular dysfunction as an added feature. To date, 15 genes and 3 loci have been identified with the USH1G gene being an uncommon cause of USH. We describe an atypical USH1G-related phenotype caused by a novel homozygous missense variation in a patient with profound hearing impairment and relatively mild retinitis pigmentosa, but no vestibular dysfunction. Methods: A 26-year-old female patient with profound congenital sensorineural hearing loss, nyctalopia and retinitis pigmentosa was studied. Audiometric, vestibular and ophthalmologic examination was performed. A panel of 13 genes was tested by next-generation sequencing (NGS). Results: While the hearing loss was confirmed to be profound, the vestibular function resulted normal. Although typical retinitis pigmentosa was present, the age at onset was unusually late for USH1 syndrome. A novel homozygous missense variation (c.1187T>A, p.Leu396Gln) in the USH1G gene has been identified as causing the disease in our patient. Conclusions: Genetic and phenotypic heterogeneity are very common in both isolated and syndromic retinal dystrophies and sensorineural hearing loss. Our findings widen the spectrum of USH allelic disorders and strength the concept that variants in genes that are classically known as underlying one specific clinical USH subtype might result in unexpected phenotypes.

Recent reports concerning the use of acupuncture as a possible treatment for sensorineural hearing impairment were reviewed and evaluated. It was concluded that acupuncture has no effect upon the hearing ability of individuals with sensorineural losses. Further, it was suggested that subjective feelings of improvement represent a placebo effect resulting from the application of a treatment that patients believe might work and not from acupuncture itself.

Ganglion Neurons

Inner ear hair cells (HCs) and spiral ganglion neurons (SGNs) are the core components of the auditory system. However, they are vulnerable to genetic defects, noise exposure, ototoxic drugs and aging, and loss or damage of HCs and SGNs results in permanent hearing loss due to their limited capacity for spontaneous regeneration in mammals. Many efforts have been made to combat hearing loss including cochlear implants, HC regeneration, gene therapy, and antioxidant drugs. Here we review the role of autophagy in sensorineural hearing loss and the potential targets related to autophagy for the treatment of hearing loss.

This middle-aged gentleman with no previous medical history presented to the local ENT outpatient clinic complaining of right-sided hearing loss.  No history of trauma or previous head and neck surgery was elicited. Following clinical and auditory assessment a right sensorineural hearing loss was confirmed.  A right-sided facial palsy was additionally identified on examination. A MRI of the internal auditory meati was performed (Figure 1a & 1b).  Following radiologist review, MRI and MRA of the brain was undertaken.   DISCUSSION   Auditory impairment is a condition with a legion of potential causes. One of the routine aspects of the assessment process for those with sensorineural hearing loss is MR imaging (MRI) of the internal auditory meati (IAMS).   The vast majority of MRI studies are normal, however one of the more commonly identified pathologies are cerebrovascular abnormalities. The most well recognised is neurovascular conflict of the vestibulocochlear nerve by a vascular loop at the root entry zone (REZ), however a broader range of potential responsible structural abnormalities are known. A wide range of processes for auditory dysfunction have been outlined.1 These include; cerebral ischaemia events, subarachnoid haemorrhage, cerebrovascular malformations and rarely dural arteriovenous fistulas (dAVFs).   Dural AVF's are abnormal vascular communications between the dural venous sinuses and an arter(ies) - most frequently branches of the external carotid artery. Sensorineural hearing impairment is one of the rarer presenting symptoms. The mechanism for hearing impairment is believed to result from either direct vascular compression on the vestibulocochlear nerve from an enlarged aberrant draining vein or from a vascular steal phenomenon (Figures 2a & 2b). An engorged draining vein from the dAVF causing mechanical compression on the nerve is the most well recognized.2 A single prior case has been reported of compression from an intraossesous dAVF of the skull base.3   The arteriovenous fistula may be directed identified (Figure 3) along with the associated signs of enlarged cerebral cortical veins and white matter change of venous hypertension (Figure 4).

Most adults with Alport syndrome (AS) suffer from progressive sensorineural hearing loss. However, little is known about the early characteristics of hearing loss in children with AS. As a part of the EARLY PRO-TECT Alport trial, this study was the first clinical trial ever to investigate hearing loss in children with AS over a timespan of up to six years Nine of 51 children (18%) had hearing impairment. Audiograms were divided into three age groups: in the 5–9-year-olds, the 4-pure tone average (4PTA) was 8.9 decibel (dB) (n = 15) in those with normal hearing and 43.8 dB (n = 2, 12%) in those with hearing impairment. Among the 10–13-year-olds, 4PTA was 4.8 dB (healthy, n = 12) and 41.4 dB (hearing impaired, n = 6.33%). For the 14–20-year-olds, the 4PTA was 7.0 dB (healthy; n = 9) and 48.2 dB (hearing impaired, n = 3.25%). On average, hearing thresholds of the hearing impaired group increased, especially at frequencies between 1–3 kHz. In conclusion, 18% of children developed hearing loss, with a maximum hearing loss in the audiograms at 1–3 kHz. The percentage of children with hearing impairment increased from 10% at baseline to 18% at end of trial as did the severity of hearing loss.

Abstract Background Glutaric aciduria type 1 (GA-1) is a rare disease connected with speech delay and neurological deficits. However, the audiological and otologic profiles of GA-1 have not yet been fully characterized. To our knowledge, this is the largest study of comprehensive audiological and otologic evaluation in patients with GA-1 to date. Methods Thirteen patients diagnosed with GA-1 between January 1994 and December 2019 with audiological, radiological and genetic manifestations were retrospectively analyzed. Hearing tests were performed in all patients. MRI was performed for radiological evaluation. Results Hearing loss was found in 76.9% (10/13) of GA-1 patients, including slight hearing loss in 46.1% (6/13) of patients, mild hearing loss in 15.4% (2/13) of patients, and moderate hearing loss in 7.7% (1/13) of patients. Normal hearing thresholds were seen in 23% (3/13) of patients. Patients with intensive care unit (ICU) admission history showed significantly worse hearing than those without (29.17 ± 12.47 vs 13.56 ± 3.93 dB HL, 95% CI 2.92–24.70, p = 0.0176). One patient had moderate sensorineural hearing loss and a past history of acute encephalopathic crisis. No usual causative gene mutations associated with hearing loss were found in these patients. MRI showed a normal vestibulocochlear apparatus and cochlear nerve. One patient with extensive injury of the basal ganglia on MRI after acute encephalopathic crisis was found to have moderate sensorineural hearing loss. Two patients with disability scores above 5 were found to have mild to moderate hearing impairment. No obvious correlation between macrocephaly and hearing loss was found. Conclusion A high prevalence of hearing impairment is found in GA-1 patients. Adequate audiological evaluation is essential for these patients, especially for those after encephalopathic crises or with ICU admission history.
