TO STUDY THE INCIDENCE OF SENSORINEURAL HEARING LOSS POST MENINGITIS IN NEONATES

Background:Post meningitis hearing impairment is an important public health problem. Neonatal meningitis is an important cause of mortality and morbidity in neonates in future life. An important consequence is hearing loss. Hearing plays a basic and important role in language, speech and intellectual development. Late detection causes irreversible stunting of the language development potential of the child. Early detection and intervention would help to maximize linguistic competence and literacy development for children who are deaf or hard of hearing. The study of brainstem evoked response audiometry provides an opportunity to evaluate the functional integrity of auditory pathway from inner ear to upper brainstem. Aim:This study was conducted to determine the incidence of sensorineural hearing loss following meningitis in neonates. Material and Methods:The present study was conducted in the Department of Pediatrics, Government Medical College Srinagar. All the patients,Term neonates with CSF culture proven bacterial meningitis. , were referred to the Department of ENT, SMHS Hospital Srinagar, of the institution for thorough ENT checkup, to exclude any ear pathology and BERA (Brainstem Evoked Response Audiometry). Results:In our study total number of cases were 87. Majority of our studied children i.e. 47 (54%) were < days of age whereas 40 (46%) children were 8-28 days of aged. The mean age of our study patients was 15.7+3.71.Out of 87 patients in our study, male predominance was observed with 55.2% males versus 44.8% females with a male to female ratio of 1.2:1. Hearing loss was observed in 11 (12.6%) of our study children.Bilateral hearing loss was seen in 5 of the 11 children (5.7%) while as unilateral hearing loss was observed in 6 of the 11 children (6.9%). Out of a total of 11 (12.6%) patients who had hearing loss, 6 (6.9%) were having mild hearing loss, followed by 3 (3.4%) children with profound hearing loss while as moderate and severe hearing loss was observed in 1 (1.1%) patients each. Conclusion: Hearing loss is not a rare complication asociated with meningitis in neonates, early detection and appropriate treatment is needed to prevent language , speech and intellecual damage.

Evoked Response Audiometry

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.

Evoked Response Audiometry

Background: Leopard syndrome is a rare case, only around 200 cases has been reported worldwide. Leopard syndrome is abbreviation for multipel Lentigines, Electrocardiographic conduction, Ocular hypertelorism, Pulmonary stenosis, Abnormality of genitalia, Retardation of growth, and sensorineural Deafness. This disorder suggests a possible relation between PTPN11 gene mutations and distinct clinical features. Purpose: This case is presented so that ENT specialists could identify signs and symptoms of Leopard Syndrome which manifest as sensorineural hearing loss (SNHL). Case: We report a 29 year old woman with multiple lentigines, scoliosis and atrial septal defect. She has 4 year old twin boys, one of them has cryptorchidism and a 10 month old girl with asymmetric septal hypertrophy and they also have multipel lentigines. They were referred to ENT Department for auditory function screening since Leopard syndrome is suspected. The audiometry of the mother reveals mild conductive deafness (40 dB) in right ear due to tympanic membrane perforation. Audiometry of the twin boys reveals sensorineural hearing loss above 4000 Hz frequency. Brainstem Evoked Response Audiometry (BERA) of the daughter reveals mild sensorineural hearing loss (40 dB )on right ear. Genogram shows that the disorders is dominant autosomal inherited. Management: Periodic auditory examination for sensorineural hearing loss is recommended since delayed onset could occur. Conclusion: Sensorineural hearing loss is a mani-festation of Leopard syndrome that should be assessed early and periodically to detect delayed onset. Keywords: Sensorineural hearing loss (SNHL), Leopard syndrome, generalized lentiginosa.

Background: Early identiﬁcation of congenital hearing loss and early intervention ameliorated many adverse consequences. This study was performed to observe effectiveness of otoacoustic emission in screening of hearing loss in high-risk babies.Methods: Prospective study on 45 high-risk newborns delivered during period of 2013-2014. Selective newborn hearing performed with oto acoustic emissions (OAE) and auditory brain stem responses (ABR), in high-risk infants aged below 7 days, 15 days, after 45 days and after 90 days.Results: Study population comprised of 45 high-risk newborns. In 1st level screening, 28 (62%) babies showed recordable OAE, 17 (38%) babies failed. In 2nd level screening 31 (81%) passed and 7 (19%) failed and death occurred in 7 infants. In 3rd level screening both OAE and brain stem evoked response audiometry (BERA), was performed in 38 cases and positivity was reported in 37 cases. 4th level screening was similar to 3rd level screening where 3 babies failed ABR test. In our study incidence of sensorineural hearing loss found to be 78.91% (3/38×1000) per 1000 high-risk babies. Auditory neuropathy was observed in 2 (4.4%) patients. Sensitivity and specificity of OAE was 100% and 33.3% respectively. In high-risk low birth weight neonates’ sensitivity and specificity was 66.7% and 50.0%.Conclusions: In high-risk babies, appropriate time for screening with OAE is around 60 days of age. OAE are useful diagnostic tool in evaluation of high-risk neonates for early detection of sensorineural hearing loss.

Background: In developing countries, hearing loss continues to be the major public health problem. Among the various causes of hearing loss, chronic otitis media (COM) is one of the commonest. In COM, the presence of sensorineural hearing loss is well established. Our study intends to determine the prevalence of sensorineural hearing loss in chronic otitis media.Methods: This was a cross sectional descriptive study of 151 subjects between the age group of 10 and 60 years. Patients having unilateral chronic otitis media of both mucosal and squamosal types were selected. All patients were evaluated clinically and audiologically. The type, duration of disease and type of perforation is correlated with degree of sensorineural hearing loss. Interaural differences in bone conduction thresholds at 500 Hz, 1 kHz, 2 kHz and 4 kHz were also noted. Results: A statistically significant correlation was noted between type of disease and perforation with hearing loss. A significant interaural difference was noted across the speech frequencies. Sensorineural hearing loss of 19.1% was seen.Conclusions: Significant sensorineural hearing loss is seen in chronic otitis media which was greater in squamosal disease. Statistically significant correlation was noted between type of disease and type of perforation with hearing loss.

Monthly Incidence

This is the first study reporting on the incidence and clinical aspects of sudden sensorineural hearing loss (SSNHL) in South Korea. Using Health Insurance Review and Assessment Service data from 2011 to 2015, the monthly incidence of unilateral SSNHL and incidence according to patients’ sex, age, and month of diagnosis were investigated. The monthly incidence of unilateral SSNHL increased over the 5-year study period, with a mean annual incidence of 17.76 cases/ 100,000 of the population. The incidence increased with age, with most patients presenting in their 60s. There was a slight female preponderance, with a male-to-female ratio of 1: 1.35. Most new patients were diagnosed in October, and the fewest in January. In conclusion, this large-scale study indicates that unilateral SSNHL has a higher incidence among the elderly, women, and in autumn (i.e., along with colder weather).

Background: Brainstem evoked response audiometry (BERA) is a non-invasive diagnostic tool which can be used to assess the early hearing loss. The objectives of the study were to find out the risk factors for severe hearing loss in children and to evaluate the role of BERA in early diagnosis of severe hearing loss in children.Methods: The present hospital based cross sectional study was conducted on 105 children suffering from severe hearing loss. Risk factors of hearing loss was assessed in these children and brainstem evoked response audiometry was performed. Results: Out of 105 children studied risk factors for hearing loss were present in 69 cases (65.71%) in which several cases had multiple risk factors. History of prolonged stay at NICU was present in 23 cases (21.9%). 11 (10.5%) cases had suffered from meningitis while history of cerebral malaria was present in 2 cases (1.9%). History of cerebral palsy was present in 5.7% cases. The family history of hearing loss was present in 15 patients (14.3%). Bilateral severe hearing loss was present in 76 cases (72.4%) while in 13 cases (12.4%) there was bilateral severe to profound hearing loss assessed using BERA test.Conclusions: Early detection and timely intervention can not only help prevent this silent handicap of deafness but also contribute to social and economic productivity of a community.

Background: Steroids have proven efficacy in the management of sudden sensorineural hearing loss (SSNHL); however, the mode of delivery and the duration of the treatment varies amongst different centres and a consensus is yet to be established. The aim of this study was to determine the efficacy of short course intravenous methylprednisolone in the management of SSNHL.Methods: This retrospective study was conducted in the department of ENT and head and neck surgery, TUTH, institute of medicine, Kathmandu, Nepal. Record data of the cases from January 2019 to May 2020, who met the criteria of SSNHL and had received intravenous methylprednisolone for three days, were assessed for the demographic profile, duration and degree of hearing loss, co-morbidities, and hearing improvement after the therapy. Cases with incomplete documentation were excluded. Pre-admission and three days post steroid therapy pure tone audiogram investigation were compared to see the improvement retrospectively. Institutional review committee clearance was taken.Results: Out of 32 patients, the male: female ratio was 1.7:1. Mean hearing loss prior to intravenous Methylprednisolone was 77.84 dB whereas mean hearing loss three days post intravenous methylprednisolone was 69.41dB. Three patients had complete recovery, sixteen had partial recovery and thirteen had no recovery after giving three days of intravenous methylprednisolone.Conclusions: Short course intravenous methylprednisolone is effective in the treatment of SSNHL with minimal side effects.
