Hearing loss in Diabetes Mellitus  

Directory of Open Access Journals (Sweden)

Full Text Available Background: The complex arrangement of inner ear makes it potential target of hyperglycaemic damage. A study was conducted to identify the probable occurrence of hearing loss as a complication of Diabetes Mellitus (DM.Aims and objective:· To assess the hearing loss in type 2 diabetic patients and correlate with age, duration of diabetes, HbA1C.· To correlate hearing loss with nerve conduction study.Design: Cross sectional study was done involving randomly 110 Type 2 DM patients. Data regarding their age and duration of diabetes was collected. Pure tone Audiometry and Nerve conduction study was done. HbA1c level determined. Data statistically analysed using Pearson correlation coefficient.Results: Out of 110 patients 48 patients (43.6% had bilateral Sensorineural hearing in higher frequency (2000hz, 4000hz. Among them Severe hearing loss (71 dB to 90dB was seen in 7 patients (6.36%, moderately severe hearing loss (61dB to 70dB in 16 patients (14.54% and moderate hearing loss(30dB to 60 dB in 25 patients (22.7%. Among 47 patients who had diabetes for more than 10 years, 29 patients (61.7% showed at least mild hearing loss. Duration of DM and sensorineural hearing loss at 2000Hz and 4000Hz showed statistically significant correlation (Pearson coefficient r= 0.561 and r= 0.727 respectively at 0.01 level. In other frequencies no significant correlation was found. Coefficient of determination was r2=0.31(31% and r2=0.52(52% respectively between duration of DM and hearing loss at 2000Hz and 4000Hz. The correlation of hearing loss in lower frequency with HbA1c did not show any statistical significance. However HbA1c and hearing loss in higher frequency (2000 hz and 4000hz showed statistically significant correlation (Pearson coefficient r= 0.282 and r= 0.385 respectively. The correlation of hearing loss with Nerve conduction study did not show any statistical significance.

Congenital sensorineural hearing loss  

International Nuclear Information System (INIS)

The ears of 47 selected patients with congenital sensorineural hearing loss were examined with complex-motion tomography. The patients were divided into 3 general categories: those with a recognized syndrome, those with sensorineural hearing loss unrelated to any known syndrome, and those with microtia. A great variety of inner ear anomalies was detected, but rarely were these characteristic of a particular clinical entity. The most common finding was the Mondini malformation or one of its variants. Isolated dysplasia of the internal auditory canal or the vestibular aqueduct may be responsible for sensorineural hearing loss in some patients. Patients with microtia may also have severe inner ear abnormalities despite the fact that the outer and inner ears develop embryologically from completely separate systems

Sensorineural hearing loss in children.  

LENUS (Irish Health Repository)

The objective of the study was to examine the aetiology of sensorineural hearing loss (SNHL) in a paediatric population presenting to the National Centre of Medical Genetics. A retrospective chart review from 1998 to 2006. One hundred and twenty nine children were investigated for SNHL. The average age of diagnosis of hearing loss was 36 months. The degree of hearing loss was mild in 8 children, moderate in 33 children, severe in 31 children and profound in 57 children. Eighty-five children (66%) were diagnosed with a hereditary hearing loss, 11 (8%) children had an acquired hearing loss and no cause found in 33 (26%) children. This is the first report of the causes of hearing loss in Irish children. The mean age of diagnosis in our cohort is high and emphasises the need for a neonatal screening programme. There remains a number of children for whom the cause of hearing loss remains unknown.

Early detection of hearing loss  

Directory of Open Access Journals (Sweden)

Full Text Available The universal newborn hearing screening (UNHS is currently spreading in Germany, as well, even though there can be no talk of a comprehensive establishment. The introduction of UNHS in several federal states such as Hamburg, Hessen, and Schleswig-Holstein can be ascribed to the personal commitment of individual pediatric audiologists. Apart from the procurement of the screening equipment and the training of the staff responsible for the examination of the newborns, the tracking, i.e. the follow-up on children with conspicuous test results, is of utmost importance. This involves significant administration effort and work and is subject to data protection laws that can differ substantially between the various federal states. Among audiologists, there is consensus that within the first three months of a child’s life, a hearing loss must be diagnosed and that between the age of 3 and 6 months, the supply of a hearing aid must have been initiated. For this purpose, screening steps 1 (usually a TEOAE measurement and 2 (AABR testing need to be conducted in the maternity hospital. The follow-up of step 1 then comprises the repetition of the TEOAE- and AABR measurement for conspicuous children by a specialized physician. The follow-up of step 2 comprises the confirmatory diagnostics in a pediatric audiological center. This always implies BERA diagnostics during spontaneous sleep or under sedation. The subsequent early supply of a hearing aid should generally be conducted by a (pediatric acoustician specialized on children.

Imaging Evaluation of Hearing Loss  

Directory of Open Access Journals (Sweden)

Full Text Available Hearing loss is a common disorder in all societies.Radiologists are often asked to evaluate the complex inner ear structures and auditory pathways in search of a cause for hearing loss. The seemingly complex anatomy of the temporal bone can make some radiologists uncomfortable in interpretation of these studies. In this talk, we will briefly focus on the pertinent imaging anatomy and attempt to go over some of the imaging findings of sensorineural and conductive hearing loss. Optimizing imaging technique will be reviewed. A variety of causes of congenital and acquired causes of hearing loss will be examined, and multiple imaging examples will be presented. Practical tips on how to interpret these studies and how to"nreport them will be given. Imaging is also an important part of the work-up for cochlear implantation. Contraindications, timing, and imaging findings that may necessitate changes in surgical approach will be reviewed.

Drug-induced hearing loss.  

Science.gov (United States)

Hearing loss is generally due to ageing but can be caused by a wide variety of other factors, including some drugs. Many drugs that cause hearing loss are directly toxic to the inner ear or auditory nerve, leading to sensorineural deafness. Sometimes the role of a drug is only suspected after several months or even years. Drug ototoxicity is dependent on the dose and duration of exposure. Hearing loss can worsen if treatment is continued and sometimes even after the drug is withdrawn. Some ear drops contain ototoxic substances. A perforated eardrum facilitates their passage into the inner ear and increases the risk of irreversible hearing loss. Various factors increase the risk of drug-related hearing loss, including age, dehydration, reduced drug elimination (especially due to renal failure), and co-administration of other ototoxic drugs. Drugs known to cause hearing loss include: anti-infectives (especially aminoglycosides); cancer drugs (particularly cisplatin); loop diuretics such as furosemide and phosphodiesterase 5 inhibitors such as tadalafil.

Risk factors for hearing loss in elderly  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: To identify risk factors related to sensorineural hearing loss in elderly. Methods: The sample consisted of 60 selected elderly, divided into two groups: the Case Group, composed by 30 individuals, 21 females and 9 males, aged at least 60 years, presenting sensorineural hearing loss, and the Control Group, composed by 30 individuals matched on gender and age, with normal hearing. The patients were submitted to audiological anamnesis and tonal audiometry. The hearing impairment was defined according to average threshold greater than 35dBNA, in the frequencies of 1,000; 2,000 and 4,000 Hz, in the best ear. Results: Statistically significant odds ratios were: a to audiological history: noise exposure and family history of deafness; b to situations involving hearing difficulty: television, church, telephone, silent environment, spatial location of sound, difficulty with voices and noisy environment; c to otologic history: tinnitus, otorrhea and nausea; and d to medical history: visual problems, smoke, alcohol, thyroid problems and kidney disease. Conclusion: The findings of this study highlighted, for sensorineural hearing loss, risk factors related to audiologic, otologic and medical history, and to situations involving hearing difficulty.

Noise-induced hearing loss.  

Science.gov (United States)

Noise-induced hearing loss (NIHL) still remains a problem in developed countries, despite reduced occupational noise exposure, strict standards for hearing protection and extensive public health awareness campaigns. Therefore NIHL continues to be the focus of noise research activities. This paper summarizes progress achieved recently in our knowledge of NIHL. It includes papers published between the years 2008-2011 (in English), which were identified by a literature search of accessible medical and other relevant databases. A substantial part of this research has been concerned with the risk of NIHL in the entertainment sector, particularly in professional, orchestral musicians. There are also constant concerns regarding noise exposure and hearing risk in "hard to control" occupations, such as farming and construction work. Although occupational noise has decreased since the early 1980s, the number of young people subject to social noise exposure has tripled. If the exposure limits from the Noise at Work Regulations are applied, discotheque music, rock concerts, as well as music from personal music players are associated with the risk of hearing loss in teenagers and young adults. Several recent research studies have increased the understanding of the pathomechanisms of acoustic trauma, the genetics of NIHL, as well as possible dietary and pharmacologic otoprotection in acoustic trauma. The results of these studies are very promising and offer grounds to expect that targeted therapies might help prevent the loss of sensory hair cells and protect the hearing of noise-exposed individuals. These studies emphasize the need to launch an improved noise exposure policy for hearing protection along with developing more efficient norms of NIHL risk assessment. PMID:23257577

Radiation Therapy and Hearing Loss  

International Nuclear Information System (INIS)

A review of literature on the development of sensorineural hearing loss after high-dose radiation therapy for head-and-neck tumors and stereotactic radiosurgery or fractionated stereotactic radiotherapy for the treatment of vestibular schwannoma is presented. Because of the small volume of the cochlea a dose-volume analysis is not feasible. Instead, the current literature on the effect of the mean dose received by the cochlea and other treatment- and patient-related factors on outcome are evaluated. Based on the data, a specific threshold dose to cochlea for sensorineural hearing loss cannot be determined; therefore, dose-prescription limits are suggested. A standard for evaluating radiation therapy-associated ototoxicity as well as a detailed approach for scoring toxicity is presented.

Association between hearing loss and depressive symptoms in elderly  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: Hearing loss causes difficulties in speech understanding, which leads away from the family and social environment. This isolation may be associated with depressive disorders. Type of study: clinical prospective. Objective: To determine the association between hearing loss and depression in a group of non-institutionalized elderly. Method: The sample consisted of individuals aged over 60 years, undergoing complete audiological evaluation and screening for depressive symptoms with the Geriatric Depression Scale (GDS. Results: We evaluated 54 elderly, 26 (48.1% were female and 28 (51.9% males. It was found that 39 (72.2% had hearing thresholds change, and 17 (31.5% with mild hearing loss and 22 (40.7% with moderate hearing loss. Were evident signs of depression in 25 elderly (46.3%, and 22 (40.7% had hearing loss. Data analysis showed an association between hearing loss and depression (p = 0.016. Although not significant (p = 0.18, the association between the degree of hearing loss was positive in relation to the severity of the signs of depression. Conclusion: In elderly people surveyed, there was a strong association between hearing loss and signs of depression and tendency to be an association between the degree of hearing loss and the severity of the signs of depression.

Introduction to audiology: Some basics about hearing loss, hearing technologies and barriers to hearing aid use  

DEFF Research Database (Denmark)

This chapter provides background information for researchers who wish to become familiar with some basic medical and audiological aspects of hearing loss and the technology of hearing aids. It introduces (1) the disciplines involved in research on hearing loss, (2) the medical categories of hearing loss and their various effects on communication, (3) the different degrees of hearing loss as defined by different national and international organizations, (4) statistics on the preva- lence of hearing loss worldwide, (5) some technological aspects of hearing instruments, (6) sta- tistics on non-usage of hearing instruments worldwide, and (7) barriers to using hearing aids. Since hearing loss is a worldwide pervasive phenomenon which is likely to increase even further in the future, the authors point out that an understanding of the non-use of hearing aids is crucial.

Ages of hearing loss diagnosis and cochlear implantation in hearing impaired children  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Aim: Early diagnosis of hearing loss lead to early intervention and improvement of developmental skills of children with hearing loss. The present study aimed to determine the mean age of hearing loss diagnosis and cochlear implantation (CI in hearing impaired children and to compare the age of performing cochlear implantation in children who were identified by newborn hearing screening with those who were not.Methods: This cross-sectional study was conducted on 96 children with severe to profound sensorineural hearing loss who received cochlear implantation in Amir-e-Alam cochlear implantation center between the years 2008 and 2010. For data gathering, we assessed subjects' medical archives, interviewed with their parents and took medical history including demographic information, birth history and hearing loss history.Results: Mean age of hearing loss suspicion, diagnosis, hearing aids administration, Initiation of rehabilitation program, performing cochlear implantation and mean age when cochlear implantation was utilized were 6.73 (SD=5.79, 9.35 (SD=5.79, 13.41 (SD=6.10, 16 (SD=6.36, 41.25 (SD=11.12, and 42.15 (SD=11.00 months, respectively. There was statistically significant difference between them (p<0.05. 43.8% of hearing impaired children had been identified by newborn hearing screening. There was statistically significant difference between cochlear implantation operation age of children who were identified by newborn hearing screening with those who were not (p<0.0001.Conclusion: In spite of notable reduction in the age of hearing loss diagnosis and intervention during recent years, compared to international indices it is still tardy. Conducting newborn hearing screening can significantly reduce these ages.

(De)stigmatizing the silent epidemic: representations of hearing loss in entertainment television.  

Science.gov (United States)

The number of adolescents, young adults, and senior citizens experiencing hearing loss has significantly increased over the last 30 years. Despite this prevalence, hearing loss receives little attention in popular and political discourse, except in its connection to aging. Thus, hearing loss and the use of hearing aids have been stigmatized, discouraging adults from seeking hearing evaluation and screening, and justifying the lack of insurance coverage for hearing devices. This research explored how and why hearing loss continues to be stigmatized through a study of media messages about hearing loss. A textual analysis was conducted on 276 television episodes that involved d/Deaf characters and/or storylines about hearing loss and deafness from 1987 through 2013 (see Table 1). Only 11 fictional programs addressed the experience of hearing loss through 47 episodes, including Criminal Minds, Switched at Birth, House, M.D., and New Girl. Contrary to the assumption that hearing loss exclusively impacts older people, characters were typically young, attractive, working professionals who held prominent roles in the programs. For most characters, hearing loss developed suddenly and was restored by the end of the episode, with only four characters using hearing aids. Hearing loss was depicted as comical, embarrassing, lonely, and threatening to one's work. The scarcity of hearing loss portrayals, combined with the negative representations of hearing loss, could help explain why hearing loss continues to be stigmatized and overlooked, even though almost half of all Americans will eventually experience difficulty hearing.

Murine malaria is associated with significant hearing impairment  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Plasmodium falciparum malaria has been suspected to cause hearing loss. Developmental, cognitive and language disorders have been observed in children, surviving cerebral malaria. This prospective study aims to evaluate whether malaria influences hearing in mice. Methods Twenty mice were included in a standardized murine cerebral malaria model. Auditory evoked brainstem responses were assessed before infection and at the peak of the illness. Results A significant hearing impairment could be demonstrated in mice with malaria, especially the cerebral form. The control group did not show any alterations. No therapy was used. Conclusion This suggests that malaria itself leads to a hearing impairment in mice.

Auditory cortex signs of age-related hearing loss.  

Science.gov (United States)

Age-related hearing loss, or presbyacusis, is a major public health problem that causes communication difficulties and is associated with diminished quality of life. Limited satisfaction with hearing aids, particularly in noisy listening conditions, suggests that central nervous system declines occur with presbyacusis and may limit the efficacy of interventions focused solely on improving audibility. This study of 49 older adults (M = 69.58, SD = 8.22 years; 29 female) was designed to examine the extent to which low and/or high frequency hearing loss was related to auditory cortex morphology. Low and high frequency hearing constructs were obtained from a factor analysis of audiograms from these older adults and 1,704 audiograms from an independent sample of older adults. Significant region of interest and voxel-wise gray matter volume associations were observed for the high frequency hearing construct. These effects occurred most robustly in a primary auditory cortex region (Te1.0) where there was also elevated cerebrospinal fluid with high frequency hearing loss, suggesting that auditory cortex atrophies with high frequency hearing loss. These results indicate that Te1.0 is particularly affected by high frequency hearing loss and may be a target for evaluating the efficacy of interventions for hearing loss. PMID:22618352

Noise Induced Hearing Loss: A Review  

Directory of Open Access Journals (Sweden)

Full Text Available Noise induced hearing loss is one of most common hearing deficit which is almost completely preventable. The hearing loss incurred would depend on the sound qualities, duration of exposure and individual susceptibility and protection. Thereby it can be prevented as we have some set norms for the noise at work places and recreational activities. Once suspected, screening and preventive measures to prevent further progression is taken. There are legislative guidelines for noise at work places for the employers, preventive measures to be taken by employee and role of health professional in screening, assessing the hearing loss and accordingly advise for rehabilitative measures.

Changes in auditory perceptions and cortex resulting from hearing recovery after extended congenital unilateral hearing loss  

Directory of Open Access Journals (Sweden)

Full Text Available Monaural hearing induces auditory system reorganization. Imbalanced input also degrades time-intensity cues for sound localization and signal segregation for listening in noise. While there have been studies of bilateral auditory deprivation and later hearing restoration (e.g. cochlear implants, less is known about unilateral auditory deprivation and subsequent hearing improvement. We investigated effects of long-term congenital unilateral hearing loss on localization, speech understanding, and cortical organization following hearing recovery. Hearing in the congenitally affected ear of a 41 year old female improved significantly after stapedotomy and reconstruction. Pre-operative hearing threshold levels showed unilateral, mixed, moderately-severe to profound hearing loss. The contralateral ear had hearing threshold levels within normal limits. Testing was completed prior to, and three and nine months after surgery. Measurements were of sound localization with intensity-roved stimuli and speech recognition in various noise conditions. We also evoked magnetic resonance signals with monaural stimulation to the unaffected ear. Activation magnitudes were determined in core, belt, and parabelt auditory cortex regions via an interrupted single event design. Hearing improvement following 40 years of congenital unilateral hearing loss resulted in substantially improved sound localization and speech recognition in noise. Auditory cortex also reorganized. Contralateral auditory cortex responses were increased after hearing recovery and the extent of activated cortex was bilateral, including a greater portion of the posterior superior temporal plane. Thus, prolonged predominant monaural stimulation did not prevent auditory system changes consequent to restored binaural hearing. Results support future research of unilateral auditory deprivation effects and plasticity, with consideration for length of deprivation, age at hearing correction, degree and type of hearing loss.

Hearing Loss Protection Using Vitamins  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Aim: Machine-made life along with the industrialization of the societies has caused the human to deal with a kind of stressful environment made up of aching sound and vibration sources. Noisiness has been one of the biggest problems of today’s world that the people are in danger of its painful effects. Auditory disorder is the most common reason for Adult Acquired Hearing Loss. As a result, protection against auditory disorders seems to be necessary. Method: In accordance with the importance of this idea, a number of researches in the field of nutrition which resulted in finding the relation between NIHL and vitamins have been carried out. Through the assessment the fact that vitamins can have both preventative and curing influence on NIHL has been evident. Furthermore, it has been discovered that the deficiency of above-mentioned instances can in a way increase the sensitivity of auditory system to noise. Result: There are various mechanisms for NIHL, and each vitamin in a way can go against the destructive affection of it (NIHL. For instance, vitamins A,C and E along with Magnesium can wipe out the free radicals produced by noise exposure. Making use of Antioxidants combinations like vitamin E can prevent auditory cells from death and Noise Induced Hearing Loss from coming about.Conclusion: Vitamin A deficiency increases the sensitivity of auditory system to noise and as a result increases the susceptibility to NIHL. Vitamin C by preventing DNA Oxidation and Lipid Peroxidation in Cochlea has preventive and therapeutic effects on NIHL. Vitamin B12, B6 Deficiency and Folic Acid by damaging Stereo Vascular increase the vulnerability to NIHl. The mechanism and how vitamins affect each of above-mentioned instances will be covered within the article in details.

Gene therapy for sensorineural hearing loss.  

Science.gov (United States)

Gene therapy is a promising treatment modality that is being explored for several inherited disorders. Multiple human gene therapy clinical trials are currently ongoing, but few are directed at hearing loss. Hearing loss is one of the most prevalent sensory disabilities in the world, and genetics play an important role in the pathophysiology of hearing loss. Gene therapy offers the possibility of restoring hearing by overcoming the functional deficits created by the underlying genetic mutations. In addition, gene therapy could potentially be used to induce hair cell regeneration by delivering genes that are critical to hair cell differentiation into the cochlea. In this review, we examine the promises and challenges of applying gene therapy to the cochlea. We also summarize recent studies that have applied gene therapy to animal models of hearing loss.

Sudden hearing loss after dental treatment.  

Science.gov (United States)

A 66-year-old man presented with impaired balance, tinnitus, sensation of blockage, and hearing loss in his left ear, which developed after dental treatment for dental pain 4 days previously. Treatment of the carious left upper second molar tooth had included pulp extirpation, canal expansion, and tooth filling under local anesthesia with articaine and epinephrine. Impaired balance decreased spontaneously within 3 days of dental treatment, but tinnitus and hearing loss persisted. Pure tone audiogram showed profound sensorineural hearing loss in the left ear, with a downslope from 40 to 100 dB, and an abnormal speech discrimination score (50%). Treatment included intravenous prednisolone, intratympanic dexamethasone, and oral betahistine and trimetazidine. The patient had improved hearing and resolution of tinnitus. Sudden hearing loss is rare after dental treatment, and awareness of this complication may prompt early referral for treatment and may improve recovery and prognosis. PMID:23642550

A 74-year-old man suffered contralateral hearing loss after left acoustic neuroma surgery. Steroid therapy was administered, but no improvement was observed. Contralateral hearing loss is an extremely rare and distressing complication that can occur following acoustic neuroma surgery. Although the mechanism of this rare phenomenon remains unclear, we speculate that in this patient the loss of cerebrospinal fluid or internal auditory artery thrombosis may be involved.

[Pharmacotherapy of acute and chronic hearing loss].  

Science.gov (United States)

The aetiology of acute hearing loss is mostly idiopathic like sudden sensorineural hearing loss and rarely infectious or vascular. Several studies and meta-analyses of pharmacotherapy are reviewed: In chronic tinnitus there is no indication for pharmacotherapy; sometimes a possible psychosomatic comorbidity has to be treated with psychopharmaceutical agents. Despite a low level of evidence treatment with steroids and initially plasma expanding infusions is recommended for acute tinnitus if there is no spontaneous remission. Intratympanic steroid therapy can be used as an alternative if there is severe hearing loss together with tinnitus. PMID:20811867

Vibrant Soundbridge rehabilitation of sensorineural hearing loss.  

Science.gov (United States)

The Vibrant Soundbridge is a means to rehabilitate patients with sensorineural hearing loss. It differs from hearing aids in that it uses mechanical energy rather than acoustic sound to deliver better sound quality to the inner ear. The implant's crucial component is a floating mass transducer that is directly fixed to the incus to drive it, which is introduced into the middle ear through a facial recess approach. Although this is a newer technology, studies thus far have demonstrated better hearing results compared with hearing aids in terms of functional gain and speech intelligibility, and better outcomes on subjective assessments.

Sensorineural Hearing Loss in Chronic Otitis Media  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: Conductive hearing loss due to chronic otitis media (COM can be treated by surgery. COM, however, may be associated with functional damage to the inner ear. Sensorineural hearing loss (SNHL due to COM has been found to be significant by some authors, whereas it has been considered negligible by others. The present study aimed to answer the question; Does COM cause SNHL ? Methods: 120 patients with unilateral COM admitted for tympano-mastoidectomy were selected for this observational case-control study. Air conduction threshold (ACT and bone conduction threshold (BCT averages were calculated at the speech frequencies (500, 1000, 2000Hz and 4 KHz, in affected (case ear and non affected (control ear and then entered in the questionnaire along with intraoperative findings. Multiple statistical tests were used to clarify the relationships between SNHL and COM. Results: COM was seen to be associated with SNHL. The Threshold shift was more accentuated at 4 KHz in older patients. SNHL at 4 KHz seemed to be higher than that at the speech frequencies. There was a significant positive relationship between the elevated BCT and duration of COM. The relationship between elevated BCT and cholesteatoma was also significant. Conclusion: The inner ear is vulnerable to COM. The proximity of the sensory cells to the potential source of harm (inflamed middle ear may mean higher exposure, as reflected by the fact that sensory cells processing high frequencies are more seriously damaged. SNHL in affected ear is strongly dependant on duration of disease.

Assessment of Hearing Loss by OAE in Asphyxiated Newborns  

Science.gov (United States)

Background: Severe birth asphyxia (apgar < 7 at the 5th minute of birth) is recognized as a hearing loss risk factor by the joint committee on infant hearing (JCIH). About half of the newborns with hearing loss do not indicate any sign and risk factor at birth. Accordingly, the joint committee recommended performance of hearing screening test in 2000, especially for babies born with risk factors. Objectives: The aim of this study was to evaluate hearing loss in asphyxiated neonates. Early diagnosis would result in early treatment of these newborns. Patients and Methods: We assessed the relationship between asphyxia and hearing impairment in newborns admitted to a referral hospital, Tehran, Iran within 3 years (2003 - 2006). Hearing problems were diagnosed and followed by otoacoustic emission (OAE) in the third and fifth days of birth. Asphyxiated neonates with abnormal OAE were referred to an ENT specialist; second OAE and tympanometry were carried out after 2 weeks. Based on the results, newborns underwent treatment or were discharged. Results: Of 149 asphyxiated neonates, 80 had mean first minute apgar score of 4.01, and mean 5th minute score was 7.24. Two percent (3/149) of asphyxiated neonates had abnormal OAEs. No statistical correlation was found between the 5th minute apgar score and abnormal OAE (P value = 0.391). However, a significant relationship between the mean birth weight and abnormal OAE (P value = 0.0406) was found. Conclusions: It seems that birth asphyxia is not correlated with hearing loss.

Gd enhanced MRI in sensorineural hearing loss  

International Nuclear Information System (INIS)

The enhanced MRI hearing findings of the inner ear in 124 patients with sensorineural hearing loss were evaluated. MR images were obtained before and after the intravenous administration of gadolinium (0.1 mmol/kg). In three out of seventy-nine patients with unilateral healing loss, cochlear and/or the vestibular enhancement was noted on the symptomatic side. The positive cases included those with Ramsay-Hunt syndrome, mumps and so-called sudden deafness. Forty-five patients with bilateral hearing loss showed no enhancement within the inner ear. Although positive gadolinium enhancement of the inner ear may detect inflammatory lesions due to a viral infection, its incidence in sensorineural hearing loss, including cases of sudden deafness. seems to be extremely rare.

Hearing loss in divers: a 6-year prospective study.  

Science.gov (United States)

Occupational diving is associated with hearing loss, but the cause is disputed. Our aim was to follow a cohort of divers through the first 6 years of their career in order to look for evidence of permanent threshold shift associated with diving activity, occupational noise exposure or acute injuries. Hearing was measured by pure tone audiometry in 67 participants at a basic course for working divers. Hearing thresholds were adjusted for age (ISO 7029). The subjects were examined and interviewed by an otologist. Additional medical and exposure data were recorded in questionnaires and personal logbooks. The procedure was repeated after 3 and 6 years. None of the subjects suffered inner ear barotrauma or inner ear decompression sickness during follow-up. Middle ear barotrauma was common. The prevalence of subjective hearing difficulties increased during follow-up, and there was a significant threshold shift at 4 kHz (mean 2.6 dB, 95% confidence interval 0.9-4.3 dB). Both subjective and objective hearing loss was associated with occupational noise exposure, but not with diving frequency or with a history of middle ear barotrauma. In the absence of manifest inner ear barotrauma or inner ear decompression sickness, noise seems to be the most important cause of long-term hearing loss in occupational divers. This study did not find evidence of long-term hearing loss caused by uneventful diving per se. PMID:21246211

Fractionated Stereotactic Radiotherapy of Vestibular Schwannomas Accelerates Hearing Loss  

International Nuclear Information System (INIS)

Objective: To evaluate long-term tumor control and hearing preservation rates in patients with vestibular schwannoma treated with fractionated stereotactic radiotherapy (FSRT), comparing hearing preservation rates to an untreated control group. The relationship between radiation dose to the cochlea and hearing preservation was also investigated. Methods and Materials: Forty-two patients receiving FSRT between 1997 and 2008 with a minimum follow-up of 2 years were included. All patients received 54 Gy in 27-30 fractions during 5.5-6.0 weeks. Clinical and audiometry data were collected prospectively. From a “wait-and-scan” group, 409 patients were selected as control subjects, matched by initial audiometric parameters. Radiation dose to the cochlea was measured using the original treatment plan and then related to changes in acoustic parameters. Results: Actuarial 2-, 4-, and 10-year tumor control rates were 100%, 91.5%, and 85.0%, respectively. Twenty-one patients had serviceable hearing before FSRT, 8 of whom (38%) retained serviceable hearing at 2 years after FSRT. No patients retained serviceable hearing after 10 years. At 2 years, hearing preservation rates in the control group were 1.8 times higher compared with the group receiving FSRT (P=.007). Radiation dose to the cochlea was significantly correlated to deterioration of the speech reception threshold (P=.03) but not to discrimination loss. Conclusion: FSRT accelerates the naturally occurring hearing loss ithe naturally occurring hearing loss in patients with vestibular schwannoma. Our findings, using fractionation of radiotherapy, parallel results using single-dose radiation. The radiation dose to the cochlea is correlated to hearing loss measured as the speech reception threshold.

Full Text Available Abstract Background It is recognized that the size of tympanic membrane(TM perforation is proportional to the magnitude of hearing loss, however, there is no clear consensus on the effect of the location (site of the perforation on the hearing loss. Hence the study is set to investigate the relationship between the location of perforation on TM and hearing loss. Methods A cross-sectional prospective study of consecutive adult patients with perforated TM conducted in the ENT clinic of University College Hospital Ibadan between January 1st 2005 and July 31st 2006. Instruments used for data collection/processing include questionnaires, video and micro-otoscopy, Pure tone audiometer, image J and SPSS packages. Results Sixty-two patients (22-males, 40-females, aged 16–75 years (mean = 35.4 +/- 4 with 77 perforated ear drums were studied and 15(24.2% had bilateral TM perforations, 21 (33.9% right unilateral and 26(41.9% left unilateral. The locations of the TM perforations were 60(77.9% central, 6(9.6% antero-inferior, 4(5.2% postero-inferior, 4(5.2% antero-superior and 3(3.9% postero-superior respectively with sizes ranging from 1.51%–89.05%, and corresponding hearing levels 30 dB – 80 dB (59% conductive and 41% mixed. Fifty-nine percent had pure conductive hearing loss and the rest mixed. Hearing losses (dBHL increased with the size of perforations (P = 0.01, r = 0.05. Correlation of location of perforations with magnitude of hearing loss in acute TM perorations was (P = 0.244, r = 0.273 and for chronic perforations (p = 0.047 & r = 0.31. Conclusion The location of perforation on the tympanic membrane (TM has no effect on the magnitude of hearing loss in acute TM perforations while it is significant in chronic ones.

Viral Causes of Hearing Loss: A Review for Hearing Health Professionals  

Digital Repository Infrastructure Vision for European Research (DRIVER)

A number of viral infections can cause hearing loss. Hearing loss induced by these viruses can be congenital or acquired, unilateral or bilateral. Certain viral infections can directly damage inner ear structures, others can induce inflammatory responses which then cause this damage, and still others can increase susceptibility or bacterial or fungal infection, leading to hearing loss. Typically, virus-induced hearing loss is sensorineural, although conductive and mixed hearing losses can be ...

Acquired Hearing Loss and Psychiatric Symptoms  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: World Health Organization (WHO defines hearing loss as an impairment in perception, attention and organisation as well as in speaking, In this study, on the base of biopsychosocial theory, we aimed to determine both psychiatric symptoms of the patients who have acquired (but ideopathic hearing impairment/loss, and also, if there was, an association between this physical illness and psychiatric symptoms. Methods: The groups of patients with mild, moderate and severe hearing impairment and a healthy control group were enrolled in the study. Each group contained 30 persons. A sociodemographic questionnaire, the Symptom Check List 90-Revised Form (SCL-90-R and the Non-Patients Form of Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (SCID-NP were used. Results: The psychopathology that have been found in our study was 35.6% in patients group versus 20% in controls. 30-50% of patients with hearing loss reported both social and psychological problems. According to SCL-90-R, in the patients’ groups who had especially moderate and severe hearing loss were more paranoid and depressive; they had more eating and sleeping difficulties; also they complained more from musical hallucinations (25% and their scores of positive symptoms and of additional scales in SCL-90-R were higher than the controls (p< 0.001. In SCID-NP, especially the hallucination, the paranoia and the depression scores were higher in patients with hearing loss. Conclusion: The reasons for psychiatric symptoms in the patients with hearing impairment or loss are multiethiological and it is known that disability is the major ethiological factor. The results of our study showed us that the psychiatry and the other medical disciplines should always work together. (Archives of Neuropsychiatry 2009; 46: 149-56

Hearing loss in elderly patients in a family practice.  

Science.gov (United States)

OBJECTIVE: To investigate hearing loss in elderly patients. DESIGN: Cohort study. SETTING: Family practice. PATIENTS: All ambulatory patients 65 years of age or older who attended the practice from June to August 1989. OUTCOME MEASURES: The Hearing Handicap Inventory for the Elderly--Screening Version (HHIE-S) and the Welch-Allyn Audioscope. Patients who failed one or both of the screening tests were referred to a speech and hearing clinic for audiologic assessment and treatment recommendations. Those with hearing aids were excluded from the main study but were given the opportunity to have them assessed at the clinic. MAIN RESULTS: Of 157 eligible patients 42 were excluded: 16 refused to participate, 13 already had hearing aids, and 13 could not be contacted. Of the remaining 115, 34 failed one or both of the tests (14 failed the HHIE-S, 9 failed the audioscope test, and 11 failed both). Of the 34, 25 completed the audiologic assessment at the clinic. Fifteen were found to have severe hearing impairment; the recommendation was hearing aids for 12, further assessment for 2 and no treatment for 1. Of the remaining 10 patients it was thought that 6 would benefit from hearing aids. Ten of the 11 patients with hearing aids who agreed to undergo testing at the clinic were found to need an adjustment or replacement of their devices. CONCLUSIONS: Hearing loss is a significant problem in elderly patients in primary practice. Further study is required to determine which of the two screening tools is most effective. Most elderly patients with hearing aids may require modification or replacement of their devices. PMID:2009476

Sensorineural hearing loss in insulin-dependent diabetic patients  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Among patients who have sensorineural hearing loss of unknown etiology, diabetes is one of the diseases to be routinely investigated. The relationship between diabetes mellitus and hearing loss is still controversial. The purpose of this study was to examine the prevalence of sensorineural hearing loss in patients with insulin-dependent diabetes mellitus (IDDM compared to control group.Methods: In a cross-sectional study pure tone audiometry (PTA and speech audiometry was performed in 62 patients with insulin-dependent diabetes mellitus (IDDM, aged under 40 years, and in 62 randomly selected age-matched non-diabetic control subjects. Subjects with otological and other metabolic diseases were excluded from the study. We applied the SPSS.10 statistical analysis software Chi-square and student's test. Results: Statistical analysis showed that the hearing of the diabetic patients were significantly worsen than the control subjects. The hearing level tended to be worsen in the diabetic patients than that in control subjects, but the differences were statistically significant only at frequencies of 250,500, 4000 and 8000 Hz p>0.05(. There wasn't statistical significant difference between sex in two study groups p>0.05(. The mean duration of diabetes was no statistically significant with hearing loss p>0.05(. The frequency of complications such as retinopathy, nephropathy, and neuropathy in the diabetic groups had no correlation with speech threshold (p>0.05(.? There were no significant differences between speech reception threshold, speech discrimination score and acoustic reflex in two groups.Conclusions: We conclude that type I diabetes mellitus can cause sensorineural hearing loss.

Classification and hearing evolution of patients with sudden sensorineural hearing loss  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english The aim of this study was to analyze clinical aspects, hearing evolution and efficacy of clinical treatment of patients with sudden sensorineural hearing loss (SSNHL). This was a prospective clinical study of 136 consecutive patients with SSNHL divided into three groups after diagnostic evaluation: [...] patients with defined etiology (DE, N = 13, 10%), concurrent diseases (CD, N = 63, 46.04%) and idiopathic sudden sensorineural hearing loss (ISSHL, N = 60, 43.9%). Initial treatment consisted of prednisone and pentoxifylline. Clinical aspects and hearing evolution for up to 6 months were evaluated. Group CD comprised 73% of patients with metabolic decompensation in the initial evaluation and was significantly older (53.80 years) than groups DE (41.93 years) and ISSHL (39.13 years). Comparison of the mean initial and final hearing loss of the three groups revealed a significant hearing improvement for group CD (P = 0.001) and group ISSHL (P = 0.001). Group DE did not present a significant difference in thresholds. The clinical classification for SSNHL allows the identification of significant differences regarding age, initial and final hearing impairment and likelihood of response to therapy. Elevated age and presence of coexisting disease were associated with a greater initial hearing impact and poorer hearing recovery after 6 months. Patients with defined etiology presented a much more limited response to therapy. The occurrence of decompensated metabolic and cardiovascular diseases and the possibility of first manifestation of auto-immune disease and cerebello-pontine angle tumors justify an adequate protocol for investigation of SSNHL.

Evaluation of age-related hearing loss.  

Science.gov (United States)

Age-related hearing loss (presbycusis) is characterized by an increased hearing threshold and poor speech understanding in a noisy environment, slowed central processing of acoustic information, and impaired localization of sound sources. Presbycusis seriously affects the older people's quality of life. Particularly, hearing loss in the elderly contributes to social isolation, depression, and loss of self-esteem. Current amplification methods related to auditory rehabilitation can provide improved communication ability to users. But, simple auditory rehabilitation is ineffective in managing the central auditory processing disorder and the psychosocial problem of presbycusis. The evaluation of central auditory processing disorder and psychosocial disorder in presbycusis should not be overlooked while providing auditory rehabilitation. PMID:24653906

SOX10 mutations mimic isolated hearing loss.  

Science.gov (United States)

Ninety genes have been identified to date that are involved in non-syndromic hearing loss, and more than 300 different forms of syndromic hearing impairment have been described. Mutations in SOX10, one of the genes contributing to syndromic hearing loss, induce a large range of phenotypes, including several subtypes of Waardenburg syndrome and Kallmann syndrome with deafness. In addition, rare mutations have been identified in patients with isolated signs of these diseases. We used the recent characterization of temporal bone imaging aspects in patients with SOX10 mutations to identify possible patients with isolated hearing loss due to SOX10 mutation. We selected 21 patients with isolated deafness and temporal bone morphological defects for mutational screening. We identified two SOX10 mutations and found that both resulted in a non-functional protein in vitro. Re-evaluation of the two affected patients showed that both had previously undiagnosed olfactory defects. Diagnosis of anosmia or hyposmia in young children is challenging, and particularly in the absence of magnetic resonance imaging (MRI), SOX10 mutations can mimic non-syndromic hearing impairment. MRI should complete temporal bones computed tomographic scan in the management of congenital deafness as it can detect brain anomalies, cochlear nerve defects, and olfactory bulb malformation in addition to inner ear malformations.

The comparative study of reading comprehension in normal-hearing and hearing-loss student  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Aim: In different language approaches, reading is considered as a major skill. Language skills comprising listening, speaking, reading and writing are completely interlinked with each other. Thus, providing active application of listening and speaking skills, children will learn reading and writing skills easily. The aim of this research was to compare reading skills of hearing-loss students studying at exceptional schools with normal students of different degrees.Methods: The research was conducted post-traumatically using standardized 2006 PIRLS test. 80 students in fifth grade of exceptional primary schools, and first and fourth grade of exceptional high schools in Tehran City who had severe and or profound hearing loss were randomly selected along with 80 normal students in ordinary schools who were selected using available sampling method.Results: There were significant differences between reading comprehension of hearing-loss and normal students of all three grades (p<0.001. Reading comprehension in female students was significantly higher than the male ones (p<0.001. There were not any significant differences in mean reading comprehension scores of hearing-loss students in different grades which demonstrate that their reading skills had not developed in tandem with their age and school educations.Conclusion: This study shows that one of the significant concerns regarding hearing-loss students is their reading comprehension ability. Considering reading ability as one of the most important acquisitive abilities which students learn at school, evaluation of reading skills of hearing loss students as well as recognition of their strengths and weaknesses in this field is indispensable.

Age-related hearing loss, methylmalonic acid, and vitamin B12 status in older adults.  

Science.gov (United States)

Hearing loss has been associated with poor vitamin B12 status in some, but not all studies. This study examined a possible relationship between age-related hearing loss and poor B12 status in 93 older adults using different indices of B12 status. Hearing loss was defined as pure-tone average threshold > 25 decibel hearing level. Participants with methylmalonic acid (MMA) > 271 nmol/L at baseline received 1,000 g/d, and those with MMA hearing, those with impaired hearing had a significantly higher serum mean MMA concentrations in the best and the worst ears and a higher prevalence of elevated MMA (> 271 nmol/L) in the worst ear only. Thus, elevated MMA concentration may be associated with hearing loss in older adults. However, short-term B12 supplementation was unrelated to improvements in hearing status in B12-deficient individuals. PMID:18032219

Urografin in the Treatment of Sudden Sensorineural Hearing Loss  

Directory of Open Access Journals (Sweden)

Full Text Available The present study was conducted to find out whether combined treatment of intravenous urografin and corticosteroid has a therapeutic advantage over oral corticosteroid therapy in the treatment of Sudden Sensorineural Hearing Loss (SSNHL. The design of the study was an interventional and controlled clinical trial. Between 2003 and 2005, patients with SSNHL were treated in our center in Tabriz, Iran. Patients were selected if they had a hearing loss of at least 30 dB in at least 3 frequencies on audiometric testing. Audiograms were performed before admission, 1 and 2 weeks and 1 and 2 months after treatment. Patients who were put on bed rest and received intravenous urografin and hydrocortisone were compared with outpatients treated with oral steroid alone. Various descriptive analytical calculations and both Chi-square and t-test were used to analyze the data. Sixty patients were included in this study. Fifty-one patients referred to the otological clinics for the appropriate treatment within the first two weeks after the onset of hearing loss. The overall improvement of both groups was 53.3%. Seventeen (56.6% of 30 patients treated in the inpatient group who received intravenous urografin and intravenous corticosteroid had hearing improvement, while half of the outpatient group received oral corticosteroid responded positively to the treatment (p>0.05. This study revealed no significant difference in hearing improvement between the hospitalized patients who received intravenous urografin and corticosteroid and the patients who received oral corticosteroid alone.

[Relapsing polychondritis with severe hearing loss.  

Science.gov (United States)

Relapsing polychondritis is an uncommon, immune-mediated condition characterized by episodes of inflammation of cartilaginous structures, especially the ears, nose, joints and respiratory tract. RP also affects proteoglycan-rich structures such as the eyes, heart, blood vessels and inner ear. Around one third of cases are associated with other diseases such as vasculitides, connective tissue diseases or myelodysplastic syndrome. Disorders of the inner ear occur in 40-50% of patients. Profound hearing loss is rare. The aim of this study was to describe the case of a patient with relapsing polychondritis associated with severe bilateral hearing loss and clinical manifestations of systemic vasculitis. This study reinforces the importance of an early diagnosis and immediate treatment in case of severe manifestations of the disease. PMID:25440712

Bilateral Pial siderosis and hearing loss  

International Nuclear Information System (INIS)

Seven adult patients with bilateral progressive hearing loss (six male, one female; aged 40-74 years) were studied with a high-field strength (1.5-T) magnetic resonance (MR) system after previous negative workup with either air contrast or intravenous contrast medium-enhanced computed tomography (CT). In all instances, the patients showed extensive evidence of pial siderosis outlining the posterior fossa subarachnoid space. The siderosis was manifested (on long repetition time images) as an increasing susceptibility effect (hypointensity) with a prolongation of echo time. The results of this study indicate that a negative CT examination is inadequate in patients with bilateral hearing loss and that when evidence of siderosis is found on MR images, an etiology for prior subarachnoid hemorrhage must be pursued

Early investigational drugs for hearing loss.  

Science.gov (United States)

Introduction: Sensorineural hearing loss (HL) is becoming a global phenomenon at an alarming rate. Nearly 600 million people have been estimated to have significant HL in at least one ear. There are several different causes of sensorineural HL included in this review of new investigational drugs for HL. They are noise-induced, drug-induced, sudden sensorineural HL, presbycusis and HL due to cytomegalovirus infections. Areas covered: This review presents trends in research for new investigational drugs encompassing a variety of causes of HL. The studies presented here are the latest developments either in the research laboratories or in preclinical, Phase 0, Phase I or Phase II clinical trials for drugs targeting HL. Expert opinion: While it is important that prophylactic measures are developed, it is extremely crucial that rescue strategies for unexpected or unavoidable cochlear insult be established. To achieve this goal for the development of drugs for HL, innovative strategies and extensive testing are required for progress from the bench to bedside. However, although a great deal of research needs to be done to achieve the ultimate goal of protecting the ear against acquired sensorineural HL, we are likely to see exciting breakthroughs in the near future.

[Nonorganic (functional) hearing loss in children].  

Science.gov (United States)

Nonorganic (functional) hearing loss in children is characterized by hearing loss without a detectable corresponding pathology in the auditory system. It is not an uncommon disease in childhood. Typically, there is a discrepancy between elevated pure tone thresholds and normal speech discrimination in everyday life. We evaluated 85 original publications, 27 reviews and 4 textbook articles. Mean age at diagnosis was 11.3 years. Girls were affected twice as often as boys. Patient histories showed a high prevalence of emotional and school problems. Pre-existing organic hearing loss can be worsened by nonorganic causes. A brainstem audiometry should confirm the diagnosis. The differential diagnosis includes auditory processing disorder, elevated thresholds in mental retardation and auditory neuropathy. We recommend taking a personal history including biographical factors, a psychological assessment including intelligence testing and referral to a child psychiatrist. Prognosis seems to be dependent on the severity of the patient's school and/or personal problems. Categorization following the Austen-Lynch model can be a valuable prognostic factor. PMID:22534679

Sensorineural hearing loss in adults with sickle cell anaemia.  

Science.gov (United States)

Sensorineural hearing loss (SNHL) is one of the known complications of sickle cell disease (SCD). However, there is paucity of information on SNHL as a complication of SCD, especially in sickle cell anaemia (SCA) in our environment, hence this study. This was a prospective study of pure tone audiological assessment of 167 adult SCA patients in stable condition attending the adult Sickle Cell Clinic and 100 apparently healthy Haemoglobin AA adults as control in the University College Hospital, Ibadan. Their ages ranged from 15 to 56 years for SCA and 15 to 65 years for the controls, with a mean age of 24.2 (+/- 8.2) and 28.7 (+/- 11.9) years respectively. There were 94 females (56.3%) and 73 males (43.7%), fifty-two females (52%) and forty-eight males (48%), with a M:F ratio of 1:1.3 and 1:1.1 for SCA and controls respectively. Sensorineural hearing loss (SNHL) was observed in a total of 178 ears in 110 SCA patients and 68 ears in 47 controls with a prevalence of 66% and 47%, respectively. Sixty-eight patients (62%) and twenty-one controls (44.7%) had bilateral impairment, although only 18 SCA patients (11%) perceived hearing impairment. High frequency loss (4000-8000 Hz) was commonly affected in both the SCA patients and controls as compared to other frequency ranges. Low frequency range was involved in ten ears (9%) especially the right ear of some SCA patients. Decibel hearing level (dBHL) loss was in the mild range (26-40 dBHL) in 103 (58%) and 53 (78%) ears in the SCA and controls, respectively. Five patients had severe and profound dBHL loss. The range of dBHL loss was 26-43 dBHL especially in the high frequency range bilaterally for both the SCA and controls. Mean binaural hearing of 13 dBHL was recorded in both the SCA and controls for each octave frequency bilaterally in those with normal hearing while 26 and 23 dBHL were for those with impaired hearing respectively. Also, the mean dBHL for both ears was observed to be progressively worse with increasing age groupings, more especially in SCA patients. There was no significant correlation between the severity of hearing loss and the frequency of vaso-occlusive crisis. It is hoped that this study would have increased the awareness that SNHL is a common complication of SCA in our patients. There is thus the need for periodic evaluation of the auditory function of SCA patients in our environment. PMID:12518924

SETTING: Loghman Hakim Hospital, Tehran, Iran, 2000-2001. SUBJECTS (MATERIALS AND METHODS: The sample derived from patients who have been introduced to the Audiometric Center of Loghman Hakim Hospital in Tehran, Iran, and underwent an audiometric examination. Among them 100 adult patients (55 males and 45 females were selected, who suffered from hearing loss. MAIN OUTCOME MEASURES: The patients were clinically examined for TMD signs, and corresponding medical data forms were completed for each one of them. The data obtained included findings of the clinical examination: (a TMD signs, (b signs of hearing disorders (hearing loss, tinnitus, ear pain and vertigo, and (c type of hearing loss (sensory neurotic, conductive, or mixed. RESULTS: Among all patients with hearing loss, 82 patients were found to present TMD. With regard to the outbreak, in patients with hearing loss there is a 95% possibility to present TMD (min. 75%, max. 90. The signs of these 82 patients with hearing loss included 89% hearing loss, 58% tinnitus, 50% ear pain, and 42% vertigo. Out of the three types of hearing loss, the sensory neurotic type was prevailed. CONCLUSIONS: According to the results of this study it could be stated that a relationship may exist between hearing loss and signs of temporomandibular joint disorders.

Recoverable hearing loss with amphetamines and other drugs.  

Science.gov (United States)

Prolonged and sustained consumption of alcohol, heroin and volatiles had been reported to impair hearing. Amphetamine related hearing loss is clinically different from the hearing loss seen with other agents. It seems that illicit drug use could result in two clinically different types of hearing losses. In May and June of 2001, 183 men aged 18 and above who met DSM-IV criteria for substance dependence were studied in a hospital in Saudia Arabia. The purpose of the study was to ascertain the prevalence of amphetamine-related recoverable hearing loss, establish whether similar hearing loss also occurred with other drugs of abuse and determine if drug-related psychosis was more prevalent in those amphetamine users who developed this type of hearing loss. Recoverable type of hearing loss was not just seen in amphetamine users but also occurred with cannabis, heroin, alcohol, dextromethorphan and glue use. Drug-induced psychosis was three and a half times more common in those amphetamine users who developed a hearing loss. Major depression and suicidality was also more common in these individuals. This association of major depression and subsequent development of hearing loss was also found in those using other type of drugs. It was concluded that a history of major depression was a good predictor of later development of both drug-induced psychosis and hearing loss in amphetamine users, and hypoperfusion was proposed as the possible explanation.

Designer aminoglycosides prevent cochlear hair cell loss and hearing loss.  

Science.gov (United States)

Bacterial infections represent a rapidly growing challenge to human health. Aminoglycosides are widely used broad-spectrum antibiotics, but they inflict permanent hearing loss in up to ~50% of patients by causing selective sensory hair cell loss. Here, we hypothesized that reducing aminoglycoside entry into hair cells via mechanotransducer channels would reduce ototoxicity, and therefore we synthesized 9 aminoglycosides with modifications based on biophysical properties of the hair cell mechanotransducer channel and interactions between aminoglycosides and the bacterial ribosome. Compared with the parent aminoglycoside sisomicin, all 9 derivatives displayed no or reduced ototoxicity, with the lead compound N1MS 17 times less ototoxic and with reduced penetration of hair cell mechanotransducer channels in rat cochlear cultures. Both N1MS and sisomicin suppressed growth of E. coli and K. pneumoniae, with N1MS exhibiting superior activity against extended spectrum ? lactamase producers, despite diminished activity against P. aeruginosa and S. aureus. Moreover, systemic sisomicin treatment of mice resulted in 75% to 85% hair cell loss and profound hearing loss, whereas N1MS treatment preserved both hair cells and hearing. Finally, in mice with E. coli-infected bladders, systemic N1MS treatment eliminated bacteria from urinary tract tissues and serially collected urine samples, without compromising auditory and kidney functions. Together, our findings establish N1MS as a nonototoxic aminoglycoside and support targeted modification as a promising approach to generating nonototoxic antibiotics. PMID:25555219

Vision loss and hearing loss in painting and musical composition.  

Science.gov (United States)

This article considers the impact of vision and hearing loss on great painters and musical composers. The visual work of Mary Cassatt, Georgia O'Keeffe, Edgar Degas, and Claude Monet all showed alterations as their vision failed. In contrast, Gabriel Fauré, Bed?ich Smetana, and Ludwig von Beethoven wrote many of their best compositions while totally deaf, and Georg Friedrich Handel and Frederick Delius struggled to compose late in life when they lost their vision (although their hearing remained excellent). There are 2 major distinctions between the role of vision and hearing for these artistic disciplines. First, there is a surrogate means of "hearing" music, through the musical score, which allows composers to write and edit music while totally deaf. The greatest problem with deafness for a skilled composer is interference from internal noise (tinnitus). There is no surrogate for vision to allow a painter to work when the subject is a blur or the colors on the canvas cannot be distinguished. Second, although the appreciation of art is visual and that of music is auditory, the transcription of both art and musical composition is visual. Thus, visual loss does pose a problem for a composer accustomed to working with good sight, because it disrupts habitual methods of writing and editing music. PMID:24565744

Noise-induced hearing loss milestones: past and future  

Scientific Electronic Library Online (English)

Full Text Available SciELO South Africa | Language: English Abstract in english A retrospective study was conducted on the Rand Mutual Assurance (RMA) noise-induced hearing loss (NIHL) compensation claims from 1998 to 2008 to determine if the 2008 milestone agreed at the 2003 Mine Health and Safety Summit was achieved. The number and costs of NIHL compensation claims in differe [...] nt commodity sectors and workplaces were collated. A secondary analysis of the ages of employees compensated after 2008 was conducted. A complementary retrospective analysis of audiogram data investigated the percentage loss of hearing (PLH) shift in different homogeneously exposed groups and occupations at two gold mines. The compensation claims analysis indicated a significant decrease in NIHL claims from 1998 to 2008, but the milestone was not achieved. The reason may be either that claims have not been submitted timeously as required by Instruction 171 and that the current submissions are a result of pre-2003 noise exposure, or that employees who were baselined are still developing NIHL owing to ineffective hearing conservation programmes in place in the mining industry. On the basis of best practice for hearing conservation, recommendations are made for leading indicators in hearing conservation programmes and for reducing the risks of NIHL in order to achieve the 2013 milestone.

[Hearing loss and hyperthyroidism (author's transl)].  

Science.gov (United States)

The audiometric findings on 23 patients with diquited hypothyroidism for a minimum of 4 months to a maximum of 20 years are presented. Audiometric tests, including acustic impedance measurements (tympanometry, stapedius reflex) were performed on all patients before and after an adequate substitution therapy. In 12 patients there was a definite impairment of hearing before the substitution therapy. Eight of them have shown a mild to moderate sensory-neural deafness. Four showed a mixed deafness, in three of which a negative pressure of 300 mm H2O was measured in the middle ear, the fourth one had a seromucotympanon. In three patients with pure sensory-neural deafness the stapedius reflex was elicitated only 30 dB over the pure tone threshold in speech frequencies. The audiometric measurements after an adequate substitution therapy of minimum 4 months has shown a definite improvement of hearing loss. PMID:749865

Subclinical Hearing Loss, Longer Sleep Duration, and Cardiometabolic Risk Factors in Japanese General Population  

Science.gov (United States)

Hearing loss leads to impaired social functioning and quality of life. Hearing loss is also associated with sleeping disorders and cardiometabolic risk factors. Here, we determined whether subclinical hearing loss is associated with sleep duration and cardiometabolic risk factors in a cross-sectional and longitudinal study of healthy Japanese general population. 48,091 men and women aged 20–79 years who underwent medical checkups were included in a cross-sectional study, and 6,674 were included in an 8-year longitudinal study. The prevalence of audiometrically determined hearing loss (>25?dB) at 4000 and 1000?Hz increased significantly with increasing sleep duration in any age strata. Logistic regression analysis showed that compared with reference sleep duration (6?h) longer sleep duration (?8?h) was significantly associated with hearing loss, even after adjusting for potential confounding factors. Simultaneously, hearing loss was significantly associated with male sex, diabetes, and no habitual exercise. In the longitudinal study, the risk of longer sleep duration (?8?h) after 8 years was significantly greater in subjects with hearing loss at 4000?Hz at baseline. In conclusion, current results suggest a potential association of subclinical hearing loss with longer sleep duration and cardiometabolic risk factors in a Japanese general population. PMID:25214844

The influence of hearing aids on the speech and language development of children with hearing loss.  

Science.gov (United States)

IMPORTANCE Hearing loss (HL) in children can be deleterious to their speech and language development. The standard of practice has been early provision of hearing aids (HAs) to moderate these effects; however, there have been few empirical studies evaluating the effectiveness of this practice on speech and language development among children with mild-to-severe HL. OBJECTIVE To investigate the contributions of aided hearing and duration of HA use to speech and language outcomes in children with mild-to-severe HL. DESIGN, SETTING, AND PARTICIPANTS An observational cross-sectional design was used to examine the association of aided hearing levels and length of HA use with levels of speech and language outcomes. One hundred eighty 3- and 5-year-old children with HL were recruited through records of Universal Newborn Hearing Screening and referrals from clinical service providers in the general community in 6 US states. INTERVENTIONS All but 4 children had been fitted with HAs, and measures of aided hearing and the duration of HA use were obtained. MAIN OUTCOMES AND MEASURES Standardized measures of speech and language ability were obtained. RESULTS Measures of the gain in hearing ability for speech provided by the HA were significantly correlated with levels of speech (?179?=?0.20; P?=?.008) and language: ?155?=?0.21; P?=?.01) ability. These correlations were indicative of modest levels of association between aided hearing and speech and language outcomes. These benefits were found for children with mild and moderate-to-severe HL. In addition, the amount of benefit from aided hearing interacted with the duration of HA experience (Speech: F4,161?=?4.98; P?hearing. CONCLUSIONS AND RELEVANCE The degree of improved hearing provided by HAs was associated with better speech and language development in children. In addition, the duration of HA experience interacted with the aided hearing to influence outcomes. These results provide support for the provision of well-fitted HAs to children with HL. In particular, the findings support early HA fitting and HA provision to children with mild HL. PMID:24700303

[Clinical features associated with sudden hearing loss in children].  

Science.gov (United States)

Sudden sensorineural hearing loss is usually unilateral, and the cause is not identified in most adult cases. However, a specific cause has frequently been found in the case of children, in whom idiopathic sudden sensorineural hearing loss (ISHL) is comparatively rare. We investigated 20 cases of acute unilateral sensorineural hearing loss in children associated with a certain disease, but which was first diagnosed as ISHL. Thirteen patients aged 6 to 16 years old were diagnosed as having psychogenic (functional) hearing loss. Discrepancies in behavioral and objective tests are most valuable when functional hearing loss is suspected. Elevated pure-tone thresholds associated with normal distortion product otoacoustic emissions (DPOAEs) enable prompt further investigation. There are several conditions that may mimic functional hearing loss, so auditory brainstem response (ABR) testing is necessary to verify the actual cause. The unilateral profound hearing loss in 2 patients aged 7 and 11 years old was due to asymptomatic mumps proven by detecting the mumps IgM antibody. Total hearing recovery in the 125-1000 Hz frequencies occurred in one case. In 5 patients aged 6 to 12 years old with acute hearing loss and vertigo, high resolution CT imaging showed an abnormally enlarged vestibular aqueduct on the affected side. Large vestibular aqueduct syndrome should be considered in acute high-frequency sloping hearing loss with an A-B gap at low frequencies. PMID:22991853

Evaluation of Occupational Hearing Loss in Fire Fighters in Tehran  

Directory of Open Access Journals (Sweden)

Full Text Available Hearing loss is a controversial occupational disease in fire fighters because exposure to hazardous levels of noise in this job is so variable and unpredictable. In this study, audiometric assessments were performed on 117 fire fighters to evaluate their hearing loss. The results showed that the average fire fighter has a characteristic noise-induced threshold shift, with maximum hearing loss occurring at 6000 Hz. The hearing loss at the test frequencies was related to age, although the association exceeded that of general population only in 6000 Hz frequency in left ear (p=0.021. Despite finding a pattern of threshold shift typical of occupational hearing loss, it must be noted that after controlling for age, there was no strong relation between length of time on the job and the degree of hearing loss. It seems that more extensive studies are needed to evaluate this relationship.

Preliminary comparison of infants speech with and without hearing loss  

Science.gov (United States)

The speech of ten children with hearing loss and ten children without hearing loss aged 12 months is examined. All the children with hearing loss were identified before six months of age, and all have parents who wish them to become oral communicators. The data are from twenty minute sessions with the caregiver and child, with their normal prostheses in place, in semi-structured settings. These data are part of a larger test battery applied to both caregiver and child that is part of a project comparing the development of children with hearing loss to those without hearing loss, known as the Early Development of Children with Hearing Loss. The speech comparisons are in terms of number of utterances, syllable shapes, and segment type. A subset of the data was given a detailed acoustic analysis, including formant frequencies and voice quality measures. [Work supported by NIDCD R01 006237 to Susan Nittrouer.

The aim of this study was to estimate the impact of birthweight on the risk of sensorineural hearing loss in children. The study was a nested case-control study. Cases (n = 327) were identified through the Norwegian county registers of children with hearing loss, and controls (n = 391 992) were all children without hearing loss born in the same counties, identified through the Norwegian Medical Birth Registry of Norway. Case definition was mean sensorineural hearing loss (MHL) > or =35 decibel (dB) hearing level (HL) in the better-hearing ear averaged over the pure-tone hearing thresholds at 500, 1000 and 2000 Hz, diagnosed before the age of 5 years. Birthweight hearing loss of 6.3 [95% CI 2.4, 16.4], controlled for gestational age, gender, parity, maternal age and concurrent birth defects. The risk of hearing loss decreased with increasing birthweights, with adjusted odds ratios of 4.4, 3.8, 1.7 and 1.4 for the birthweights 1500-1999, 2000-2499, 2500-2999 and 3000-3499 g respectively. The risk of both mild to moderate (MHL 35-70 dBHL) and severe/profound hearing losses (MHL >70 dBHL) were influenced by birthweight. PMID:17937734

Immersive simulation of hearing loss and auditory prostheses  

Science.gov (United States)

Simulation of hearing loss is useful for demonstrating the communication challenges facing hearing-impaired people. However, current simulations, most of which are only recordings, do not actually elevate thresholds; i.e., they do not simulate hearing loss, per se. The hearing loss simulator described in this talk is immersive; the user's detection thresh- olds for ambient sounds are shifted by a prescribed degree. This threshold shift is achieved through a combination of passive attenuation (from muff-type hearing protectors) and additive masking noise (introduced by within-muff earphones). Acoustic signals picked up by microphones near each ear are processed through bandpass AGC channels and delivered via the earphones to complete the simulation of frequency-dependent hearing loss and loudness recruitment. Preliminary results validating the accuracy of specified threshold shift will be presented, along with speech-reception data comparing simulated with actual hearing losses. Subjective reactions of users engaged in one-on-one conversation suggest that strong feelings of communication disability are engendered by even moderate degrees of simulated hearing loss. The system, which is capable of simulating any degree of recruiting hearing loss along with hearing aids or cochlear implants, can provide effective interactive demonstrations of both auditory communication handicap and rehabilitation options.

Role Salience and Anticipated Work–Family Relations Among Young Adults With and Without Hearing Loss  

Science.gov (United States)

This study examined the effect of hearing status on role salience and anticipated work–family relations among 101 unmarried young adults aged 20–33 years: 35 with hearing loss (19 hard of hearing and 16 deaf) and 66 hearing. Participants completed the Life Role Salience scale, anticipated conflictual relations scale, anticipated facilitory relations scale, and a background questionnaire. The deaf participants demonstrated a significantly higher level of commitment to work but anticipated the significantly lowest level of conflict. Hearing status was a significant variable in predicting anticipated conflictual relations among all participants. Mode of communication was a significant predictor of conflictual relations among the hearing loss group. Implications for theory and practice were discussed. PMID:18209020

Medication for hearing loss after fractionated stereotactic radiotherapy (SRT) for vestibular schwannoma  

International Nuclear Information System (INIS)

Purpose: To investigate the effectiveness of corticosteroid treatments for patients showing decreases in hearing levels after stereotactic radiotherapy for vestibular schwannoma. Methods and Materials: Twenty-one patients experienced a hearing loss in pure-tone average at greater than 20 dB or less than 10 dB within 1 year after irradiation administration of 44 Gy/22 fractions followed by a 4 Gy boost. Eight received oral prednisone at a daily dose of 30 mg, which was gradually decreased (medicated group), and 13 received none (nonmedicated group). The average observation period was 26.7±16.6 (range: 6-69) months. Results: Hearing recovery was seen after initial onset of the hearing loss in all 8 patients in the medicated group and in 2 of 13 patients in the nonmedicated group (p=0.001). The hearing recovery, that is, the change in pure-tone average (dB) at the last follow-up from the onset of hearing loss, was 9.8±6.9 dB (recovery) in the medicated group and -9.4±12.8 dB (further loss) in the nonmedicated group (p=0.0013). The hearing recovery rate, normalizing to the degree of the hearing loss before medication, was also significantly higher in the medicated group than in the nonmedicated group (p=0.0014). Conclusions: Corticosteroidal intake is suggested to be effective in improving hearing loss after stereotactic radiotherapy, at least in young patients having a useful pretreatment hearing level, if the treatment for hearing loss is administered immediately aftng loss is administered immediately after the hearing loss is first detected

Hearing Loss Due to Familial Hypercholesterolemia and Statin Treatment  

Directory of Open Access Journals (Sweden)

Full Text Available It has been suggested that high cholesterol levels might have adverse effects on hearing and interest- ingly statins may have beneficial effects on hearing loss. Herein, we share a dramatic improvement in acute hearing loss by statin administration in a young patient with familial hypercholesterolemia. To our knowledge this is the first report indicating the possible role of statins in patients suffering from sudden hearing loss in the context of familial hypercholesterolemia. Although the statin administra- tion as a therapeutic option for sudden hearing loss needs to be clarified in prospective studies, this case report might shed more light for possible association of dyslipidemia and hearing loss and role of statins in such cases.

Pediatric hearing loss: common causes, diagnosis and therapeutic approach.  

Science.gov (United States)

Pediatric hearing loss limits the child ability to develop effective auditory and speech capabilities. Early rehabilitation of hearing loss results in higher levels of linguistic, academic and social skills. To achieve the best outcomes, proper and timely diagnosis is essential. The etiology of hearing loss can be classified according to its nature as sensorineural hearing loss (SNHL), conductive hearing loss (CHL) or mixed hearing loss (MHL). Congenital hearing loss could be genetic or non genetic (acquired), syndromic or non-syndromic. Hearing loss can be classified according to the severity into mild (26-40 dB HL), moderate (41-70 dB HL), severe (71-90dB HL) and profound (more than 90 dB HL). Management of hearing loss is mainly influenced by the nature, the bilaterality, the severity and the age at diagnosis. Severe to profound bilateral SNHL can be managed by cochlear implantation (unilateral or bilateral), if picked up at early age while mild to moderate bilateral SNHL are easier to manage with conventional hearing aids. CHL has less impact on the speech development of the child. It is usually managed by correcting the underlying etiology such as otitis media with effusion or even surgically in cases of external ear atresia or ossicular malformations. Unilateral SNHL have fortunately no impact on the language development of the child and can be passed undiagnosed until preschool-aged children. The implementation of national newborn hearing screening programs has improved the management of affected children by rehabilitating them at early stages to allow for normal speech development. In this review article, we aim to highlight the most common causes of pediatric hearing loss, their character and presentation and to review the diagnostic and therapeutic approaches of a deaf child.

Connexin 26 and autosomal recessive non-syndromic hearing loss  

Directory of Open Access Journals (Sweden)

Full Text Available Prelingual deafness occurs with a frequency of 1 in 1000 live births and is divided into syndromic and non-syndromic forms contributing 40 and 60% respectively. Autosomal recessive non-syndromic hearing loss (ARNSHL is responsible for 80% cases of childhood deafness. Nearly all genes localized for ARNSHL cause prelingual, severe to profound, sensorineural hearing impairment. ARNSHL is genetically heterogeneous and at least 39 loci have been identified. The most significant finding to date has been the discovery of mutations in GJB2 gene at the DFNB1 locus on chromosome 13q12 as the major cause of profound prelingual deafness. This was first reported in a Tunisian family in 1994 and thereafter in many different countries. GJB2 gene encodes the gap-junction protein, connexin 26 (Cx26, mutations in which have become the first genetic marker of inherited hearing loss. Allele-specific polymerase chain reaction (AS-PCR, single stranded conformation polymorphism (SSCP and sequencing methods have been developed for the detection of mutations in Cx26 gene. In India as well, the Cx26 mutations are being screened in families with hearing impaired children using these molecular methods. Therefore, in order to create awareness among the clinicians and the affected families; we have attempted to review the Cx26 gene mutations responsible for autosomal recessive type of non-syndromic hearing loss. The efficacy and utility of Cx26 gene analysis might open the path to proper counseling of families for carrier detection and prenatal diagnosis. It may even facilitate the development of strategies in future for the treatment of this common genetic disorder.

What are the audiometric frequencies affected are the responsible for the hearing complaint in the hearing loss for ototoxicity after the oncological treatment?  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: The neurosensory bilateral simetric hearing loss resulting of the oncological treatment is underestimated, because the patients has the hearing detection preserved, reporting complaints in determined situation, or the not comprehension of part of the message. Objective: Investigate which are the audiometric frequencies affected are the responsible by the presence of hearing complaints. Method: Prospective study evaluating 200 patients with cancer in the childhood out of the oncological treatment in at least 8 years, with average age to the diagnosis of 6,21 years (4,71. Was applied anamnesis to investigate the presence of hearing complaints and performed a tonal threshold audiometry. To check the association between the complaint and the hearing loss, was applied the Exact test of Fisher, with one error a=5%, the patients were split into: normal hearing, hearing loss in 8kHz, loss in 6-8 kHz, loss in 4-8 kHz, loss in 2-8 kHz and loss in < 1-8 kHz. Results: We found 125 patients with hearing loss, 10 presented hearing complaints. Between the patients with hearing loss, 16 presented loss only at 8kHz, and 1 with complaint; 22 with loss in 6-8 kHz, being 3 with complaint; 16 with loss in 4-8 kHz, from them 10 with complaint; 15 with loss 2-8 kHz, being 14 with complaint and 6 with loss in < 1-8 kHz all with complaints. There were a significant relationship between the loss and hearing complaint (p<0,001, when the frequency of 4 kHz was involved. Conclusion: The bigger the number of affected frequencies the bigger the occurrence of hearing complaint, most of all when the speech frequencies are involved, and the involvement of 4 kHz already determines the appearing of the complaints.

Disacusia neurossensorial imunomediada Immunomediated sensorineural hearing loss  

Directory of Open Access Journals (Sweden)

Full Text Available A disacusia neurossensorial imunomediada (DNSI é caracterizada geralmente por uma disacusia neurossensorial bilateral, progressiva e assimétrica, acompanhada ou não por outros sintomas da orelha interna. Três pacientes com DNSI cujo quadro clínico e audiométrico eram sugestivos de doença auto-imune, e apresentaram resposta positiva à terapia imunossupressora ou pesquisa positiva de anticorpo anti hsp-70 68kD, foram estudados com relação às características clínicas, testes diagnósticos, alternativas terapêuticas e evolução da doença. Dois pacientes apresentaram quadro de disacusia neurossensorial rapidamente progressiva, associado a quadro vestibular, e outro, quadro de surdez súbita unilateral. Nenhum paciente apresentou positividade às provas reumatológicas, e apenas um paciente apresentou aumento na velocidade de hemossedimentação. Nenhum paciente obteve resposta adequada sustentada à corticoterapia, mas dois deles melhoraram com outras terapias imunossupressoras. O diagnóstico da DNSI é clínico e baseado na resposta positiva ao teste terapêutico com imunossupressores. A pesquisa de anticorpo anti-hsp70 de 68 kD pelo Western Blot é o único exame laboratorial específico para seu diagnóstico, possuindo sensibilidade de 42% e especificidade de 90%. Apenas 1 paciente apresentou positividade para este teste e não respondeu à terapia imunossupressora. Os dois pacientes com teste negativo responderam satisfatoriamente ao tratamento. A baixa sensibilidade do Western Blot e seu alto custo dificultam sua difusa utilização em nosso meio.

Sensorineural Hearing Loss Associated with Kawasaki Disease  

Directory of Open Access Journals (Sweden)

Full Text Available Kawasaki disease (KD is an acute systemic vasculitis of children characterized by fever, rash, conjunctival hyperemia, oropharyngeal erythema, edema and erythema of the hands and feet, and cervical adenopathy [1]. A variety of other features are also characteristics of this syndrome, including coronary artery aneurysms, urethritis, anterior uveitis, mild hepatobiliary dysfunction, and gallbladder hydrops. Coronary artery abnormalities, including aneurysms and ectasia, occur in approximately 20% of untreated patients [2]. Neurologic involvement is rare. Cranial nerve palsy, especially involving the seventh nerve, has been reported [3], as well as hemiparesis caused by cerebral thrombosis and infarction, and convulsions. Although about 30% of patients with acute KD in the United States have been reported to suffer mild sensorineural hearing loss (SNHL [4], only a few such cases have been reported in Japan. On the other hand, in both countries, a few cases of severe or profound SNHL in children who were in the acute phase of KD have been documented [5].

Directory of Open Access Journals (Sweden)

Full Text Available Background and Aim: Reading skill is one of the most important necessities of students' learning in everyday life. This skill is referred to the ability of comprehension, comment and conclusion from texts and receiving the meaning of the massage which is composed. Educational development in any student has a direct relation with the ability of the comprehension. This study is designed to investigate the effects of hearing loss on reading comprehension in hearing-impaired students compared to normal-hearing ones.Methods: Seventeen hearing-impaired students in 4th year of primary exceptional schools in Karaj, Robatkarim and Shahriyar, Iran, were enrolled in this cross-sectional study. Seventeen normal-hearing students were randomly selected from ordinary schools next to exceptional ones as control group. They were compared for different levels of reading comprehension using the international standard booklet (PIRLS 2001. Results: There was a significant difference in performance between hearing-impaired and normal- hearing students in different levels of reading comprehension (p<0.05.Conclusion: Hearing loss has negative effects on different levels of reading comprehension, so in exceptional centers, reconsideration in educational planning in order to direct education from memorizing to comprehension and deeper layers of learning seems necessary.

Clinical study on unilateral hearing loss in children  

International Nuclear Information System (INIS)

A series of 60 children was studied (aged 0 to 10 years, 32 boys, 28 girls) with severe unilateral sensorineural hearing loss of unknown etiology. There were two peaks, at 0 and 6 years. In 19 children, hearing loss was identified during a conservative general health checkup for school or preschool children. In 21 children aged 0 years, 16 were suspected of hearing loss by newborn hearing screening. Temporal bone computed tomography scans were examined in 51 patients. Sixteen ears (31.4%) with hearing loss had inner ear and/or internal auditory canal abnormalities. In one patient, the anomaly was the presence of a bony wall dividing the internal auditory canal into two separate compartments associated with severe inner ear hypoplasia. Two patients had a common cavity. In one of these patients, the anomaly was revealed because of severe bacterial meningitis, and another was detected by newborn hearing screening. Six patients had a narrow internal auditory canal, 4 had a narrow internal auditory canal and hypoplastic cochlea, and 1 had a narrow internal auditory canal and cystic vestibule, and lateral semicircular canal dysplasia. Two patients had a cystic vestibule and lateral semicircular canal dysplasia. One case showed fluctuation of the hearing level in the contralateral ear with normal hearing during the observation period at an average of 20 months. The number of children whose unilateral hearing loss is detected early by newborn hearing screening has enormously newborn hearing screening has enormously increased. Strategies for follow-up, early intervention, and support for families are necessary for young children with unilateral hearing impairment. (author)

Prospective study of alcohol consumption and self-reported hearing loss in women.  

Science.gov (United States)

Chronic excess alcohol intake has been associated with irreversible hearing loss and acute alcohol intake may temporarily impair auditory function; however, some evidence suggests that long-term moderate alcohol intake may be related to lower risk of hearing loss. This study prospectively examined the association between total alcohol and individual alcoholic beverage consumption and risk of hearing loss in women. Data were prospectively collected from 65,424 participants in the Nurses' Health Study II (NHS II), aged 27-44 years at baseline (follow-up 1991-2009). Alcohol consumption was assessed using a validated questionnaire every 4 years. An incident case was defined as a self-reported hearing problem that began after 1991. Cox proportional hazards multivariate regression was used to adjust for potential confounders. During 1,024,555 person-years of follow-up, 12,384 cases of hearing loss occurred. After multivariate adjustment, there was no significant association between total alcohol consumption and risk of hearing loss. In exploratory analyses, beer consumption was associated with increased risk and wine consumption was associated with reduced risk. No significant association was observed for consumption of liquor. Total alcohol consumption is not associated with risk of hearing loss in women. The modest associations observed for beer (direct) and wine (inverse) may be due to chance or residual confounding but merit further study. PMID:25468591

A case of the vibrant soundbridge stapes coupler in patients with mixed hearing loss.  

Science.gov (United States)

The Vibrant Soundbridge (VSB) with stapes clip coupler placement at the stapes head has been used successfully to treat mixed hearing loss. Coupling between the floating mass transducer of the VSB and the stapes head is technically less demanding than incus vibroplasty and is more likely to generate a positive outcome without significantly changing residual hearing or resulting in medical or surgical complications. A 65-year-old man with bilateral mixed hearing loss and chronic otitis media underwent vibroplasty with a stapes clip coupler. Speech discrimination scores in both quiet and noise environments showed better functional gain with the VSB than with the use of a conventional hearing aid. The results of the present case show the feasibility of implanting a VSB with a stapes coupler in patients with mixed hearing loss due to chronic otitis media. PMID:25279233

Genetics of hearing loss: focus on DFNA2  

Directory of Open Access Journals (Sweden)

Full Text Available Laura M Dominguez, Kelley M DodsonDepartment of Otolaryngology, Head and Neck Surgery, Virginia Commonwealth University, Richmond, VAAbstract: The purpose of this review is to assess the current literature on deafness nonsyndromic autosomal dominant 2 (DFNA2 hearing loss and the mutations linked to this disorder. Hearing impairment, particularly nonsyndromic hearing loss, affects multiple families across the world. After the identification of the DFNA2 locus on chromosome 1p34, multiple pathogenic mutations in two genes (GJB3 and KCNQ4 have been reported. The overwhelming majority of pathogenic mutations linked to this form of nonsyndromic hearing loss have been identified in the KCNQ4 gene encoding a voltage-gated potassium channel. It is believed that KCNQ4 channels are present in outer hair cells and possibly inner hair cells and the central auditory pathway. This form of hearing loss is both phenotypically and genetically heterogeneous and there are still DFNA2 pedigrees that have not been associated with changes in either GJB3 or KCNQ4, suggesting that a possible third gene exists at this locus. Further studies of the DFNA2 locus will lead to a better understanding of progressive hearing loss and provide a better means of early detection and treatment.Keywords: deafness nonsyndromic autosomal dominant 2, nonsyndromic deafness, genetic hearing loss, GJB3, KCNQ4

Annual rate of hearing loss falls after fractionated stereotactic irradiation for vestibular schwannoma  

International Nuclear Information System (INIS)

Purpose: The rate of hearing loss in a population before and after irradiation was investigated to determine the effect of irradiation on hearing impairment. Methods and materials: In 72 patients with vestibular schwannoma who received fractionated stereotactic irradiation from 1992 to 1999, 21 had had their hearing levels examined 3 months or more before the treatment. The mean time between the initial examination and treatment was 18.6 months (range: 3-89 months), and the mean time between treatment and the last follow-up was 24.2 months (12-69 months). Thirty-six to 50 Gy in 20-25 fractions over 5 to 6 weeks was given using an X-ray beam from a linear accelerator. Pure tone average (PTA) was measured using the mean hearing level at five frequencies, and the annual rate of hearing loss was defined as [(hearing loss in PTA(dB))/(follow-up period (months)x12)]. Results: The actual cumulative curve of decrease in tumor size of 2 mm or more was 38.3% at 2 years and 80.0% at 3 years. The mean of hearing loss in PTA was 11.6±10.3 dB (-1 to 35 dB) from the initial examination to the start of irradiation and 11.9±14.4 dB (-14 to 37 dB) from the start of irradiation to the last follow-up. The mean annual rates of hearing loss before irradiation and in the 1st, 2nd, 3rd and 4th years after irradiation were, respectively, 18.6, 11.2, 6.2, 5.1, and 5.0 dB/year. The annual rates of hearing loss in the 2nd year (P=0.025) and 3rd year (P=0.018) were significantly slower than the.018) were significantly slower than the rate before irradiation. Conclusions: The mean annual rate of hearing loss was higher before irradiation than after irradiation, and hearing loss slowed rather than accelerated after irradiation. Although hearing loss after the treatment was usually permanent, fractionated stereotactic irradiation was suggested to be effective to lower the rate of hearing loss

Postnatal risk factors associated with hearing loss among high-risk preterm infants: tertiary center results from Turkey.  

Science.gov (United States)

The aim of this study was to determine the postnatal risk factors associated with hearing loss as well as the prevalence of hearing loss among high-risk preterm infants in newborn hearing screening (NHS). We performed a retrospective study of high-risk preterm infants born with a gestational age ?32 weeks and/or a birth weight ?1,500 g. A NHS procedure was performed by automated auditory brainstem response (AABR) and automated evoked otoacoustic emission (TEOAE). Infants who failed TEOAE or AABR or both tests were referred to a tertiary audiology center for diagnosis confirmation and management. Postnatal risk factors associated with hearing loss were evaluated and compared for preterm infants with and without hearing loss. 1,360 high-risk preterm infants were assessed. Permanent hearing loss was found in 19 (1.4%) infants. Multivariate analysis revealed that proven sepsis (p = 0.019), mechanical ventilation ?5 days (p = 0.024), loop diuretics (p = 0.001), patent ductus arteriosus ligation (p = 0.018) and operation for retinopathy of prematurity (ROP) (p = 0.034) were significant related factors for the hearing loss. This study showed a low prevalence of hearing loss and an association between operation for ROP and hearing loss in preterm infants, which has not been defined previously. Our results suggest that every neonatal intensive care unit should determine their own risk factors and take precautions to prevent hearing loss for these high-risk preterm infants. PMID:23917736

The effect of non-linear frequency compression on hearing skills improvement in children with profound hearing loss, using Tavana test  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Aim: Non-linear frequency compression is a new feature in hearing instruments compresses the voices of a high-frequency region above a certain cut-off point and transfers them to the lower frequency regions in order to improve the audibility. In this study, we aimed to survey the effect of this feature on the total level of hearing skills of children with profound hearing loss at the age of 3-4 years.Methods: Twenty two 3-4-years-old children with profound hearing loss were selected with improbable simple sampling. 11 of them had hearing instruments with non-linear frequency compression and 11 had traditional hearing instruments. Tavana test (Jarollahi, 2009 was used to compare the level of hearing skills in these two groups.Results: Comparison of mean scores of total level of hearing skills in two groups indicated a significant difference (p <0.001. Also, the mean scores of level in all subtests, detection (p=0.022, determination (p=0.005, recognition (p=0.039 and comprehension (p=0.010, showed significant differences.Conclusion: Using the hearing instruments with non-linear frequency compression would increase the total level of hearing skills in children with profound hearing loss at the ages of 3-4-years and also, in all skill of detection, determination, recognition and comprehension.

Epistemics in audiological consultations : Divergent conceptualizations of 'hearing' in healthcare encounters between hearing aid acoustitians and patients with hearing loss  

DEFF Research Database (Denmark)

Adult-onset hearing loss affects more than 20% of citizens in the US and in the EU. This second most frequent disability (World Health Organization 2001) is mostly due to aging and noise exposure ('sensorineural'). Although usage of hearing aids effectively increases life quality (Joore et al. 2003; Anteunis 2002), in many western countries, only 15% of those who could benefit from this technology use it, e.g. in the USA, Switzerland, and Finland (Bisgaard 2009). Technological innovation has not helped improve uptake. A longitudional interview study indicates that one barrier to hearing aid acceptance seems to lie in healthcare interactions: 88% of patients with hearing loss accessing the German healthcare system do not complete rehabilitation; the average time between first diagnosis and use of hearing aids is 8-10 years (Meis & Gabriel 2006). The present study contributes to an emering body of CA work on healthcare encounters with hearing loss which show that communication problems occur frequently between healthcare professionals and patients (e.g. Skelt 2006, Laakso 2011-2014, Ruusuvuori 2011-2014; Brouwer 2012, Heinemann et al. 2012, Egbert 2013). The presentation, based on 12 hours of naturally-occurring, video-taped audiological interactions in German, focuses on a specific communication problem which is due to an asymmetricity in "epistemic domains" (Stivers & Rossano 2010:8) in that divergences in the professional's and the patients' conceptualizations of hearing emerge and are frequently not resolved. The goal of these audiological consulations is to select and fit the best possible hearing aid for clients with hearing loss. In order to achieve this goal, audiologists routinely rely on their technological and medical knowledge, the results of a pure-tone audiogram, and the clients' subjective descriptions of hearing experiences in different environments. In these consultations, the institutional conceptualization of hearing (and thus of hearing loss) is that of an objectively measurable functioning of the ear, categorized in an audiogram by decibels and hertz. In contrast, persons with hearing loss perceive of their hearing, even during audiograms, as less precise and more varied. When asked by the audiologist about hearing experiences in different settings (e.g. dyadic conversation, multiperson interaction, telephone, outdoors, train station), the descriptions by clients are diffuse, broad, and metaphorical. Compared to visual impairment, describing hearing seems to be more difficult, and frequently, persons with hearing impairment resort to visual metaphors. A CA examination of conversational order in the areas of turn-taking, sequence, repair, topic, multimodality, and linguistic resources yields partial results for these audiological data, and including epistemics in the analysis achieves to 'grasp' the phenomenon more fully. CA research "into epistemics focuses on the knowledge claims that interactants assert, contest and defend in and through turns-at-talk and sequences of interaction” (Heritage 2013:370). Given that the audiologist and the patient frequently do not achieve a shared knowledge of the patient's hearing loss, these institutional encounters appear to be highly problematic in that the imbalance is not resolved. “(W)hen a speaker indicates that there is an imbalance of information between speaker and hearer, this indication is sufficient to motivate and warrant a sequence of interaction that will be closed when the imbalance is acknowledged as equalized for all practical purposes” (Heritage 2012: 32). The presentation concludes with connecting the interactional problems at the micro-level of direct healthcare encounters to the macro-level and globel problems of the impact of untreated hearing loss. The social repercussions are stigmatization, miscommunication, loss of work, social isolation, depression, and suicide (Carmen 2001). The financial loss per person dropping out of work due to hearing loss is estimated at 200,000 US Dollars (World Health Organization 2001). In Europe, the econmi

Efficient estimates of cochlear hearing loss parameters in individual listeners  

DEFF Research Database (Denmark)

It has been suggested that the level corresponding to the knee-point of the basilar membrane (BM) input/output (I/O) function can be used to estimate the amount of inner- and outer hair-cell loss (IHL, OHL) in listeners with a moderate cochlear hearing impairment Plack et al. (2004). According to Jepsen and Dau (2011) IHL + OHL = HLT [dB], where HLT stands for total hearing loss. Hence having estimates of the total hearing loss and OHC loss, one can estimate the IHL. In the present study, results from forward masking experiments based on temporal masking curves (TMC; Nelson et al., 2001) are presented and used to estimate the knee-point level and the compression ratio of the I/O function. A time-efficient paradigm based on the single-interval-up-down method (SIUD; Lecluyse and Meddis (2009)) was used. In contrast with previous studies, the present study used only on-frequency TMCs to derive estimates of the knee-point level. Further, it is explored whether it is possible to estimate the compression ratio using only on-frequency TMCs. 10 normal-hearing and 10 hearing-impaired listeners (with mild-to-moderate sensorineural hearing loss) were tested at 1, 2 and 4 kHz. The results showed a reasonable reliability and may be applicable to individualized hearing-aid fitting. © 2013 Acoustical Society of America.

Prevalence of Hearing Loss in Newborns Admitted to Neonatal Intensive Care Unit  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: Hearing is essential for humans to communicate with one another. Early diagnosis of hearing loss and intervention in neonates and infants can reduce developmental problems. The aim of the present study was to assess the prevalence of hearing impairment in newborns admitted to a neonatal intensive care unit (NICU and analyze the associated risk factors.   Materials and Methods: This cross-sectional study was conducted to assess the prevalence of hearing loss in neonates who were admitted to the NICU at Nemazee Hospital, Shiraz University of Medical Sciences between January 2006 and January 2007. Auditory function was examined using otoacoustic emission (OAE followed by auditory brainstem response (ABR tests. Relevant potential risk factors were considered and neonates with a family history of hearing loss and craniofacial abnormality were excluded. For statistical analysis logistic regression, the chi-squared test, and Fisher’s exact test were used.    Results: Among the 124 neonates included in the study, 17 (13.7% showed hearing loss in the short term. There was a significant statistical relationship between gestational age of less than 36 weeks (P=0.013, antibiotic therapy (P= 0.033, oxygen therapy (P=0.04, and hearing loss. On the contrary, there was no significant relationship between hearing loss and use of a ventilator, or the presence of sepsis, hyperbilirubinemia, congenial heart disease, transient tachypnea of newborn, congenital pneumonia, or respiratory distress syndrome.  Conclusion: Auditory function in neonates who are admitted to a NICU, especially those treated with oxygenor antibiotics and those born prematurely, should be assessed during their stay in hospital. The importance of early diagnosis of hearing loss and intervention in these neonates and avoidance of any unnecessary oxygenor antibiotic therapy needs to be further promoted.

Hearing loss in the cervico-oculo-acoustic (Wildervanck) syndrome.  

Science.gov (United States)

A 22-year-old woman with mixed hearing loss, Klippel-Feil anomalad (fused cervical vertebrae), and bilateral abducens palsy with retracted bulb (Duane's syndrome) is classified as having the cervico-oculo-acoustic syndrome or Wildervanck syndrome. In this syndrome, the unilateral or bilateral congenital hearing loss is usually severe and of neurosensory origin. To our knowledge, this is the third case of this syndrome with the classical triad and a mixed hearing loss. It is the second case in which an exploratory tympanotomy was performed. An ankylosis of the stapes was found. Stapedectomy and Teflon interposition were successfully carried out. Since the triad of the cervico-oculo-acoustic syndrome can be incomplete, a review of the association of Klippel-Feil anomalad and hearing loss is also presented, with special attention to the anomalies of the ossicular chain.

Cisplatin is a commonly-used chemotherapeutic agent that is highly-effective against a variety of pediatric cancers. Unfortunately, it may lead to ototoxicity, with serious consequences on the quality of life of survivors. Patients remain at risk of progression of ototoxicity even after completion of treatment. We report the case of a medulloblastoma survivor with previously documented normal hearing, who developed significant hearing loss and tinnitus following exposure to excessive noise at a nightclub three years after completion of treatment. We highlight the importance of long-term audiological follow up and education about the increased risk of hearing loss in this population. PMID:25439704

This approach is geared towards developing new products, systems, technologies and practices based on an understanding of why so few persons with hearing loss use the highly advanced hearing technologies. In integrating Conversation Analysis (“CA”), audiology and User Centered Design, three disciplines which are collaborating together for the first time, we are addressing the following questions: Who is the user? What are the interactional situations in which hearing loss and hearing aids are relevant? How can Conversation Analysis contribute to innovation? What are the challenges in such a collaboration?

Using the extended parallel process model to prevent noise-induced hearing loss among coal miners in Appalachia  

Energy Technology Data Exchange (ETDEWEB)

Occupational noise-induced hearing loss is the second most self-reported occupational illness or injury in the United States. Among coal miners, more than 90% of the population reports a hearing deficit by age 55. In this formative evaluation, focus groups were conducted with coal miners in Appalachia to ascertain whether miners perceive hearing loss as a major health risk and if so, what would motivate the consistent wearing of hearing protection devices (HPDs). The theoretical framework of the Extended Parallel Process Model was used to identify the miners' knowledge, attitudes, beliefs, and current behaviors regarding hearing protection. Focus group participants had strong perceived severity and varying levels of perceived susceptibility to hearing loss. Various barriers significantly reduced the self-efficacy and the response efficacy of using hearing protection.

Hearing loss disorders associated with renal disease.  

Science.gov (United States)

There are several syndromes in which both hearing and renal function are impaired. The two best known are branchio-oto-renal (BOR) syndrome and Alport syndrome. These are reviewed along with several other rarer syndromes. BOR is especially important since it is likely to be first recognized by the otolaryngologist because of the hearing and branchial anomalies. It is important for the practicing otolaryngologist to recognize these disorders and to ensure that renal problems are being treated. In addition, the syndromes discussed here are all hereditary and referral to a clinical geneticist may be helpful to the individual and family. PMID:21358188

Sensorineural hearing loss caused by a high jugular bulb.  

Science.gov (United States)

A 15-year-old female presented with sensorineural hearing loss related to a high jugular bulb. She noticed temporary worsening of her right hearing with mild dizziness when her neck was compressed whereas she noticed no change in her left hearing. An audiogram showed temporary worsening of low tone bone-conduction on such occasions. A large jugular bulb covering the right round window was observed through the perforation. Computed tomography (CT) revealed a large jugular bulb obliterating the round window niche. Deterioration of bone conduction during neck compression was thought to be caused by the protrusion of the jugular bulb into the inner ear via the round window. This case suggested the possibility of sensorineural hearing loss due to the jugular bulb. As in the present case, jugular bulb or vein-related ear disorders should be examined by neck compression.

Hair Color and Hearing Loss: A Survey in a Group of Military Men  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: It has been shown that low levels of pigmentation increase susceptibility to noise-induced hearing loss in humans. For this reason, white populations develop more pronounced noise- induced hearing loss in comparison to black populations. Similarly, blue-eyed individuals exhibit greater temporary threshold shift than brown-eyed subjects; still, no strong correlation has been verified between the lightness of hair color and susceptibility to noise-induced hearing loss. This study was performed with the purpose of investigating a possible association between hair color and the degree of hearing loss due to firing noise. Study Design: Prospective observational study. Setting: A tertiary referral center with an accredited otorhinolaryngology-head & neck surgery department.   Materials and Methods: A total of 57 military recruits were divided into two groups; light-colored (blond and light brown and dark-colored hair (dark brown and black. The two groups were matched based on history of firing noise exposure (number of rounds; type of weapon and the level of hearing loss at 2, 3, 4, 6 and 8 kHz sound frequencies was compared between them.   Results: The results showed that the mean level of hearing loss of light-colored hair individuals (20.5±17dB was significantly greater than that of dark-haired subjects (13.5±11dB, (P=0.023.   Conclusion: The results indicate that hair color (blond versus black can be used as an index for predicting susceptibility to noise-induced hearing loss in military environments. Therefore, based on the individual's hair color, upgraded hearing conservation programs are highly recommended.

Determination of Hearing Loss Prevalence in Preschool Children of Ahwaz  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: Children learn to communicate by hearing sounds. If there is hearing loss, the cognitive and speaking abilities and language learning will deteriorate. Early detection and intervention are important factors in the successful treatment of hearing loss in children. Hearing loss (HL is divided into two main groups: conductive hearing loss (CHL and sensorineural hearing loss (SNHL, the prevalence of the former being higher in children, many whose causes are easy to detect and treat. Material and Methods: In this descriptive, cross-sectional study, 785 children, aged 6-7 years, entering elementary school Grade 1 in the school year 2010/2011, were randomly selected from 10% of Ahwaz Hearing Loss Screening Centers, and their audiograms were studied. The collected data were analyzed using SPSS and descriptive statistics. Results: Out of the 785 preschool children examined in this study, 77 children (9.8% suffered from HL (42.9% female and 57.1% male, 59.7% from CHL, and 40.3% from SNHL. Twenty-six percent suffered from bilateral HL and 74% from unilateral HL. Thirty-eight point ninety-six percent had abnormal tympanometry, 61% of whom were Type B. Most of the children (53% had mild HL. Thirty-one point two percent of parents were aware of their children's HL. Conclusion: Considering the high prevalence of HL, especially SNHL, in this study, which is usually permanent but detectable at the neonatal ages, raising public awareness and early screening of ear diseases, which can lead to the detection and treatment in most cases, seem to be vital.

Hearing loss in otitis media with effusion- types and management- a study of hundred cases  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction- Serous Ottis media or otitis media with effusion is a common cause of hearing loss of acute onset. The common presentation will be a block or reduced hearing possible after a travel or flight. Most of the cases present with conductive hearing loss while some may present with mixed or even pure sensory hearing loss. Background- we study hundred patients diagnosed with serous otitis media for the type of hearing loss and characterize the management strategy. Conclusion- Serous otitis media is a common cause of hearing loss which is mostly conductive and is amenable to treatment while some rare cases which may persist may require assistive hearing with amplification. Although sensorineral hearing loss is rare in otitis media, it is seen in practice along with mixed hearing loss. The pathophysiology of the neural affection of hearing loss remains a mystery although many theories exist.

Diffusion-Based Model for Noise-Induced Hearing Loss  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Among several different damaging mechanisms, oxidative stress is found to play an important role in noise-induced hearing loss (NIHL). This is supported by both findings of oxidative damage after noise exposure, and the fact that upregulation of antioxidant defenses seem to reduce the ears susceptibility to noise. Oxidative stress mechanisms could help explain several of the characteristics of NIHL, and we therefore believe that it would be advantageous to estimate noise-induced hearing...

Acute unilateral hearing loss as an unusual presentation of cholesteatoma  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Cholesteatomas are epithelial cysts that contain desquamated keratin. Patients commonly present with progressive hearing loss and a chronically discharging ear. We report an unusual presentation of the disease with an acute hearing loss suffered immediately after prolonged use of a pneumatic drill. Case presentation A 41 year old man with no previous history of ear problems presented with a sudden loss of hearing in his right ear immediately following the prolonged use of a pneumatic drill on concrete. The cause was found to be a fractured long process of incus which had been eroded by the presence of an attic cholesteatoma. A tympanomastoidectomy and ossiculoplasty was performed with good result. Conclusion Cholesteatomas may be asymptomatic and insidious in their onset. This case illustrates the point that an indolent disease such as this may present in unusual ways and the clinician must always have a high index of suspicion combined with thorough assessment and examination of every patient.

Intratympanic injection of dexamethasone for treatment of tinnitus in patients with sudden sensorineural hearing loss  

Directory of Open Access Journals (Sweden)

Full Text Available The purpose of this study is to test the effectiveness of intratympanic dexamethasone injections as a treatment for severe tinnitus in idiopathic sudden sensorineural hearing loss (SNHL. We studied 37 patients who received intratympanic dexamethasone injections and 14 control patients who did not receive it, with severe tinnitus after onset of unilateral sudden SNHL. Hearing level did not change during this study in any patient. The relationship between the duration of tinnitus and effectiveness of treatment was investigated in sudden SNHL. We used a visual analogue scale to evaluate 51 patients with severe tinnitus at the stage of stable hearing level after idiopathic sudden sensorineural hearing loss. Forty-one per cent of patients showed significant improvement after treatment. The average period between onset of sudden sensorineural hearing loss and initiation of intratympanic dexamethasone injection was significantly shorter (207 days in the improved group than in the unchanged group (482 days (P<0.001. In control group, one of 14 patients presented significant improvement spontaneously. Intratympanic dexamethasone treatment may be effective in treatment of severe tinnitus after sudden SNHL at the stage of stable hearing level, and the shorter the period from onset of sudden deafness to the start of intratympanic dexamethasone treatment, the greater the improvement in tinnitus that can be expected.

Frequency selectivity in canaries with a hereditary hearing loss  

Science.gov (United States)

Sensorineural hearing loss is associated with reduced frequency selectivity due to the broadening of the auditory filters in mammals. In European starlings, hearing loss caused by the ototoxic drug kanamycin results in the widening of auditory filters at 5 kHz [Marean et al. (1998)]. In the present study, we examine frequency selectivity in a bird with a permanent hereditary hearing impairment, the Belgian Waterslager (BWS) canary. This strain of canary has long been bred for its loud, low-frequency song, and has been shown to have a hearing loss primarily at higher frequencies (2 kHz and above). Using operant conditioning and the method of constant stimuli, thresholds for detecting pure tones in flat-spectrum broadband noise were measured in BWS and non-BWS canaries. Critical ratios were calculated for comparison with other species of birds. At higher frequencies, critical ratios for BWS canaries were much larger than those of non-BWS canaries and other birds, suggesting reduced frequency selectivity in the region of the birds' hearing loss.

Sensorineural hearing loss after concurrent chemoradiotherapy in nasopharyngeal cancer patients  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Sensorineural hearing loss (SNHL is one of the major long term side effects from radiation therapy (RT in nasopharyngeal cancer (NPC patients. This study aims to review the incidences of SNHL when treating with different radiation techniques. The additional objective is to determine the relationship of the SNHL with the radiation doses delivered to the inner ear. Methods A retrospective cohort study of 134 individual ears from 68 NPC patients, treated with conventional RT and IMRT in combination with chemotherapy from 2004-2008 was performed. Dosimetric data of the cochlea were analyzed. Significant SNHL was defined as > 15 dB increase in bone conduction threshold at 4 kHz and PTA (pure tone average of 0.5, 1, 2 kHz. Relative risk (RR was used to determine the associated factors with the hearing threshold changes at 4 kHz and PTA. Results Median audiological follow up time was 14 months. The incidence of high frequency (4 kHz SNHL was 44% for the whole group (48.75% in the conventional RT, 37% with IMRT. Internal auditory canal mean dose of > 50 Gy had shown a trend to increase the risk of high frequency SNHL (RR 2.02 with 95% CI 1.01-4.03, p = 0.047. Conclusion IMRT and radiation dose limitation to the inner ear appeared to decrease SNHL.

Hearing Loss and Cognitive Decline Among Older Adults  

Science.gov (United States)

Background Whether hearing loss is independently associated with accelerated cognitive decline in older adults is unknown. Methods We studied 1984 older adults (mean age 77.4 years) enrolled in the HealthABC study, a prospective observational study begun in 1997–98. Our baseline cohort consisted of participants without prevalent cognitive impairment (Modified Mini-Mental State [3MS] scores ? 80) who underwent audiometric testing in Year 5. Participants were followed for 6 years. Hearing was defined at baseline using a pure-tone average (PTA) of thresholds at 0.5 – 4 kHz in the better-hearing ear. Cognitive testing was performed in Years 5, 8, 10, and 11 and consisted of the 3MS (measuring global function) and the Digit Symbol Substitution test (DSS, measuring executive function). Incident cognitive impairment was defined as a 3MS score 5 points from baseline. Mixed-effects regression and Cox models were adjusted for demographic and cardiovascular risk factors. Results Individuals with baseline hearing loss (PTA > 25 dB, n = 1162) had rates of decline in 3MS and DSS scores that were 41% and 32% greater, respectively, than those in normal hearing individuals (3MS: ?0.65 points/year [95% CI: ?0.73 – ?0.56] vs. ?0.46 points/year [95% CI: ?0.55 – ?0.36], p=.004; DSS: ?0.83 points/year [95% CI: ?0.94 – ?0.73] vs. ?0.63 points/year [95% CI: ?0.75 – ?0.51], p=.015). Compared to those with normal hearing, individuals with hearing loss had a 24% (Hazard ratio: 1.24 [95% CI: 1.05 – 1.48]) increased risk of incident cognitive impairment. Rates of cognitive decline and the risk of incident cognitive impairment were linearly associated with the severity of an individual’s baseline hearing loss. Conclusion Hearing loss is independently associated with accelerated cognitive decline and incident cognitive impairment in community-dwelling older adults. Further studies investigating the mechanistic basis of this association and whether hearing rehabilitative interventions could affect cognitive decline are needed. PMID:23337978

Correlation between hearing loss and the results of the following questionnaires: Hearing Handicap Inventory for the Adults - Screening Version HHIA-S and Hearing Handicap Inventory for the Elderly - Screening Version - HHIE-S  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: The self-assessment questionnaires are useful to measure the emotional and social/transient consequences resulting from hearing loss, and they can be used in a wide range of situations in the clinical routine, such as auditory screening. Objective: Check the sensitivity and specificities of HHIA-S and HHIE-S questionnaires to identify a hearing loss and their usages in auditory screenings, as well as analyze the ability of these questionnaires to detect different degrees of hearing impairments in the studied people. Method: Retrospective study with 51 individuals aged between 18 and 88, who filled out the Hearing Handicap Inventory for Adults Screening Version - HHIA-S and Hearing Handicap Inventory for the Elderly Screening Version - HHIE-S questionnaires at the waiting room of the Brazilian Unified Health System (SUS's otorhinolaryngology infirmary. Results: The instruments showed a low sensitivity (47%, not identifying individuals with a hearing loss; however, they showed a high specificity (75%, accurately identifying individuals with no hearing disorder. Moreover, no significant association between the degree of hearing loss and the constraint degree for participation was found. Conclusion: the aforementioned questionnaires revealed a low sensitivity and a high specificity, proving to be ineffective for auditory screenings in a group with previous hearing complaints in addition to being unable to detect different types and degrees of hearing impairment.

A case of acute bilateral retrocochlear hearing loss as an initial symptom of unilateral thalamic hemorrhage.  

Science.gov (United States)

A speech discrimination test is a test using a list of 25 phonetically balanced monosyllables. It is often overlooked but significant enough for pure tone audiometry. Many physicians have performed pure tone audiometry but without a speech discrimination test. A 73-year-old woman visited our clinic complaining of sudden bilateral hearing loss. Pure tone audiometry showed only bilateral high frequency loss. However, speech discrimination had decreased markedly. We decided to follow-up after 1 week of Ginexin-F® (ginkgo leaf extract) and Nafril® (nafronyl oxalate). She felt a gait disturbance within 2 days. Magnetic resonance imaging revealed a left thalamic hemorrhage. After a 1 month hospitalization, the hematoma subsided, and speech discrimination recovered 3 months later. Acute hearing loss due to thalamic hemorrhage that recovered has never been reported. We report the first case of retrocochlear hearing loss that occurred with a thalamic hemorrhage in a patient who recovered. PMID:25279230

The More the Worse: the Grade of Noise-Induced Hearing Loss Associates with the Severity of Tinnitus  

Directory of Open Access Journals (Sweden)

Full Text Available Tinnitus disturbs lives and negatively affects the quality of life of about 2% of the adult world population. Research has shown that the main cause of tinnitus is hearing loss. To analyze a possible association of the degree of hearing loss with the severity of tinnitus, we have performed a retrospective study using admission data on 531 patients suffering from chronic tinnitus. We have found that 83% of our tinnitus patients had a high frequency hearing loss corresponding to a noise-induced hearing loss (NIHL. There was a significant correlation between the mean hearing loss and the tinnitus loudness (p < 0.0001. Interestingly, patients suffering from decompensated chronic tinnitus had a greater degree of hearing loss than the patients with compensated form of tinnitus. In addition, we demonstrate that the degree of hearing loss positively correlates with the two subscales (“intrusiveness” and “auditory perceptional difficulties” of the Tinnitus Questionnaire. Our retrospective study provides indirect evidence supporting the hypothesis that the degree of noise-induced hearing loss influences the severity of tinnitus.

Sensorineural hearing loss following irradiation to the malignant tumor of the head and neck  

International Nuclear Information System (INIS)

We observed sensorineural hearing loss following X-ray irradiation to the malignant tumor of head and neck. There were 24 patients whose auditory organs lied within the irradiation field. Ten of these patients were affected by sensorineural hearing loss. Hearing loss occurred at a high frequency in elderly patients, epipharynx tumor and high dose of irradiation. Many cases revealed high tone hearing loss. Most cases showed about a 20?30 dB hearing loss, so their impediment seemed not severe in daily life. In some of these cases, we could have temporal bone findings, but there were no particular findings relevant to sensorineural hearing loss. (author)

Changes in the default mode networks of individuals with long-term unilateral sensorineural hearing loss.  

Science.gov (United States)

Hearing impairment contributes to cognitive dysfunction. Previous studies have found changes of functional connectivity in the default mode network (DMN) associated with cognitive processing in individuals with sensorineural hearing loss (SNHL). Whereas the changes in the DMN in patients with long-term unilateral SNHL (USNHL) is still not entirely clear. In this work, we analyzed resting-state functional magnetic resonance imaging (fMRI) data and neuropsychological test scores from normal hearing subjects (n=11) and patients (n=21) with long-term USNHL. Functional connectivity and nodal topological properties were computed for every brain region in the DMN. Analysis of covariance (ANCOVA) and post hoc analyses were conducted to identify differences between normal controls and patients for each measure. Results indicated that the left USNHL presented enhanced connectivity (p<0.05, false discovery rate (FDR) corrected), and significant changes (p<0.05, Bonferroni corrected) of the nodal topological properties in the DMN compared with the control. More changes in the DMN have been found in the left than right long-term USNHL (RUSNHL). However, the neuropsychological tests did not show significant differences between the USNHL and the control. These findings suggest that long-term USNHL contributes to changes in the DMN, and these changes might affect cognitive abilities in patients with long-term USNHL. Left hearing loss affects the DMN more than the right hearing loss does. The fMRI measures might be more sensitive for observing cognitive changes in patients with hearing loss than clinical neuropsychological tests. This study provides some insights into the mechanisms of the association between hearing loss and cognitive function. PMID:25463518

Contrast-enhanced MR imaging of the endolymphatic sac in patients with sudden hearing loss  

International Nuclear Information System (INIS)

Our objective was to evaluate the frequency of contrast enhancement of the endolymphatic sac in patients with sudden hearing loss. Forty consecutive patients with sudden sensorineural hearing loss (20 males and 20 females; age range 11-82 years), 40 age-matched control subjects, and 5 patients with Meniere's disease were examined using the same imaging protocol on a 1.5-T MR system. Pre- and post-contrast-enhanced T1-weighted 3D spoiled gradient-echo sequence (3D SPGR; TR/TE=23/10 ms, no. of excitations=1, flip angle=30 ) images were obtained using a voxel size of 0.6 x 0.7 x 0.8 mm3. Contrast enhancement in the area of the endolymphatic sac was assessed by two radiologists, and the frequency of contrast enhancement was compared between the three study groups. Enhancement of the ipsilateral endolymphatic sac was observed in 30 of the 40 patients with sudden hearing loss (75%). Twenty of these 30 patients also showed enhancement on the contralateral side, and 1 patient showed enhancement only on the contralateral side. Only 1 of the 5 patients with Meniere's disease showed enhancement. Nine of the 40 control subjects (22.5%) showed enhancement (bilateral enhancement in 5 subjects, unilateral in 4). The frequency of enhancement in patients with sudden hearing loss was significantly higher than that in control subjects (P<0.0001) or patients with Meniere's disease (P<0.05). The frequency of contrast enhancement of the endolymphatic sac is significantly increasendolymphatic sac is significantly increased in patients with sudden hearing loss, but further study is necessary to clarify the relationship between this finding and the pathophysiology of sudden hearing loss.

Identification and genotype/phenotype correlation of mutations in a large German cohort with hearing loss.  

Science.gov (United States)

The prevalence of hearing impairment is estimated as approximately 1 on 1,000 newborn children. To assess a higher mutation detection rate in individuals with hearing loss a three-step mutation screening program consisting of GJB2 in first line, then GJB1, GJB3 and GJB6 (second step) and if tested negative or heterozygote, testing of GJA1, GJB4, SLC26A4 and PJVK (third) was performed. Audiograms were derived from all patients to characterize audiological features of GJB2 mutations especially. In 59 patients (31.3 %) of the 188 probands, the hearing impairment was due to GJB2 mutations, 45 (23.9 %) of these being homozygous for 35delG mutation and 14 (7.4 %) compound heterozygous for GJB2 mutations in the coding region of exon 2 whereas no significant sequence variation was found in exon 1. In 22 (11.7 %) additional patients a single recessive mutation in GJB2, GJB3, GJB6 and SLC26A4 without a second mutation on the other allele was identified, making genetic counseling difficult. Our study showed significant difference in hearing loss degree in the patients with GJB2-mutations. Forty-five (45.5 %) GJB2-cases were identified in 99 individuals diagnosed with severe to profound hearing loss, 14 (17.7 %) GJB2-cases were identified in 79 individuals with moderate deafness whereas no clear GJB2 mutation was found in 10 patients with mild hearing loss (p hearing levels in identical genotypes (even intrafamilial), a significant genotype-phenotype correlation could not be established. Based on the identified mutations spectrum and frequencies, speaking mostly of GJB2, a step by step screening for mutations can be devised and in addition may lead to a better stratification of patients for specific therapeutical approaches.

Health Seeking Behavior among Parents of Children with Hearing Loss: A Cross Sectional Study  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: Prevalence of hearing loss is 11.7% of the school going population (5-15 years. Such children fail to develop speech, language and cognitive skills unless proper habilitation is initiated. If detected early and managed suitably, will have a far better chance at a normal life than those who are habilitated late or not at all. Aims & objectives: To detect the age of suspicion, identification, intervention and treatment seeking behavior of children with hearing loss. Materials & methods: This was a cross- sectional study done in Children between 5 and 15 years age-group with hearing loss, coming to an ENT OPD, New Civil Hospital, Surat during the period of 1st August 2011 to 31 July 2012. Results: A total of 246 children were studied. Mean age of the study population was 9±3.46 years. Average age at first suspicion of hearing loss was 2.9±1.7 years, first consultation was 3.5±1.5 years and first intervention was 7.8±3.3 years. There was significant association between age of first suspicion of congenital hearing loss with father’s occupation (p=0.03. There was significant association between delay in diagnosis and gender (p= 0.04. As the level of education of parents and socio- economic status increased, preference for private set ups for first consultation also increased (p< 0.05. In 63.5% cases, advice of general practitioner resulted in the delay in referral to ENT specialist. Conclusion & Recommendations: Even after primary care, an average gap of 4.3 years is observed among parents for receiving intervention. Mother is the first person to suspect hearing loss among their children. Basic training of general practitioner/ MBBS doctors regarding primary ear care is required.

Cognitive spare capacity in older adults with hearing loss  

Directory of Open Access Journals (Sweden)

Full Text Available Individual differences in working memory capacity are associated with speech recognition in adverse conditions, reflecting the need to maintain and process speech fragments until lexical access can be achieved. When working memory resources are engaged in unlocking the lexicon, there is less Cognitive Spare Capacity (CSC available for higher level processing of speech. CSC is essential for interpreting the linguistic content of speech input and preparing an appropriate response, that is, engaging in conversation. Previously, we showed, using a Cognitive Spare Capacity Test (CSCT that in young adults with normal hearing, CSC was not generally related to working memory capacity (WMC and that when CSC decreased in noise it could be restored by visual cues. In the present study, we investigated CSC in 24 older adults with age-related hearing loss, by administering the CSC Test (CSCT and a battery of cognitive tests. We found generally reduced CSC in older adults with hearing loss compared to the younger group in our previous study, probably because they had poorer cognitive skills and deployed them differently. Importantly, CSC was not reduced in the older group when listening conditions were optimal. Visual cues improved CSC more for this group than for the younger group in our previous study. CSC of older adults with hearing loss was not generally related to WMC but it was consistently related to episodic long term memory, suggesting that the efficiency of this processing bottleneck is important for executive processing of speech in this group.

Developmental plasticity of spatial hearing following asymmetric hearing loss: context-dependent cue integration and its clinical implications  

Directory of Open Access Journals (Sweden)

Full Text Available Under normal hearing conditions, comparisons of the sounds reaching each ear are critical for accurate sound localization. Asymmetric hearing loss should therefore degrade spatial hearing and has become an important experimental tool for probing the plasticity of the auditory system, both during development and adulthood. In clinical populations, hearing loss affecting one ear more than the other is commonly associated with otitis media with effusion, a disorder experienced by approximately 80% of children before the age of two. Asymmetric hearing may also arise in other clinical situations, such as after unilateral cochlear implantation. Here, we consider the role played by spatial cue integration in sound localization under normal acoustical conditions. We then review evidence for adaptive changes in spatial hearing following a developmental hearing loss in one ear, and argue that adaptation may be achieved either by learning a new relationship between the altered cues and directions in space or by changing the way different cues are integrated in the brain. We next consider developmental plasticity as a source of vulnerability, describing maladaptive effects of asymmetric hearing loss that persist even when normal hearing is provided. We also examine the extent to which the consequences of asymmetric hearing loss depend upon its timing and duration. Although much of the experimental literature has focused on the effects of a stable unilateral hearing loss, some of the most common hearing impairments experienced by children tend to fluctuate over time. We therefore argue that there is a need to bridge this gap by investigating the effects of recurring hearing loss during development, and outline recent steps in this direction. We conclude by arguing that this work points toward a more nuanced view of developmental plasticity, in which plasticity may be selectively expressed in response to specific sensory contexts, and consider the clinical implications of this.

Effects of potential neurotoxic pesticides on hearing loss: a review.  

Science.gov (United States)

Several pesticides are supposed to be neurotoxic for humans, consequently, they may also affect the auditory system. This review analyzes human and experimental animal studies testing the hypothesis that exposure to pesticides is associated with hearing loss. The literature on this topic is still sparse and methodological limitations of some papers evaluated are identified. As a whole, available data indicate a possible ototoxic action of pesticides, but alternative hypotheses could not be ruled out, also considering some confounders, such as the co-exposure to noise. Therefore, further studies are necessary in order to clarify the association between pesticides exposure and hearing loss. While awaiting more evidence, for precautionary action we recommend considering pesticides as possible ototoxic agents, in particular for vulnerable targets, such as pregnant women and children during early development.

Functional results after Bonebridge implantation in adults and children with conductive and mixed hearing loss.  

Science.gov (United States)

In patients with conductive hearing loss caused by middle ear disorders or atresia of the ear canal, a Bonebridge implantation can improve hearing by providing vibratory input to the temporal bone. The expected results are improved puretone thresholds and speech recognition. In the European Union, approval of the Bonebridge implantation was recently extended to children. We evaluated the functional outcome of a Bonebridge implantation for eight adults and three children. We found significant improvement in the puretone thresholds, with improvement in the air-bone gap. Speech recognition after surgery was significantly higher than in the best-aided situation before surgery. The Bonebridge significantly improved speech recognition in noisy environments and sound localization. In situations relevant to daily life, hearing deficits were nearly completely restored with the Bonebridge implantation in both adults and children. PMID:25425039

The Effect of Stimulus Bandwidth on Perception of Fricative /s/ among Individuals with Different Degrees of Sensorineural Hearing Loss  

Directory of Open Access Journals (Sweden)

Full Text Available Most of the speech sounds that contribute to speech intelligibility are dominated by high-frequency components. The phoneme /s/ is the third or fourth most frequently occurring phoneme in the English language and second most frequently occurring consonantal phoneme in Hindi language. Given the importance of the phoneme /s/, it is ironic that, this sound contains the highest frequency acoustic elements of any speech sound in English and most of the non-English languages ranging from 4500 Hz to more than 8000 Hz. The most common type of hearing impairment affecting speech perception is high-frequency sensorineural loss (SN and such individuals require good high frequency audibility in order to better perceive fricative cues, regardless of hearing status. While many studies appear to support the general notion that high-frequency amplification may not always be beneficial, the inter-subject variability in most studies precludes a clearly defined rule that would distinguish listeners who are likely to benefit from high-frequency amplification from those who are not. The current study is aimed to determine and compare the effective bandwidth required for the perception of fricative /s/ in individuals with normal hearing and hearing impairment as a function of degree of hearing loss. A total of 100 Hindi speaking subjects equally divided into four groups (Group I: Normal hearing, Group II: Moderate SN hearing loss, Group III: Moderately severe SN hearing loss, Group IV: Severe SN hearing loss participated in the study. Nonsense syllables containing the phonemes /s/, /f/, /?/ and /c/ in /i/ vowel context and low pass filtered at 1, 2, 3, 4, 5, 6, 7, 8 and 9 KHz produced by a female talker were used as stimulus. The results revealed that there was a statistically significant effect (p<0.05 of bandwidth for the perception /s/ between different groups at 1 KHz, 2 KHz, 3 KHz, 4 KHz, 5 KHz, 6 KHz, 7 KHz and 8 KHz and no significant effect (p>0.05 was seen at 9 KHz between groups. In addition, individuals with normal hearing required lower bandwidth for accurate fricative perception and there was a statistically significant difference (p<0.05 in mean bandwidth between groups. Among the hearing impaired group, as the degree of hearing loss increased the subjects required higher bandwidth for accurate perception of fricative. This study has important implications in knowing the effective bandwidth required for the perception of high frequency speech sounds among individuals with hearing loss on individual basis which in turn helps in the selection of appropriate rehabilitative devices.

Progress of hearing loss in neurofibromatosis type 2: implications for future management.  

Science.gov (United States)

The objective of this study was to describe changes in hearing over time in patients with neurofibromatosis type 2 (NF2) treated conservatively. A retrospective case review was conducted in a tertiary referral centre. Pure tone audiometry, speech discrimination scores, serviceable hearing (American Academy of Otolaryngology class A or B) and measurement of vestibular schwannoma (VS) size on magnetic resonance imaging were evaluated in 56 patients (89 ears) with NF2 with at least one conservatively managed VS. Over a mean follow-up period of 7 years (range 0.8-21 years) pure tone average thresholds increased gradually with a mean annual rate of 1.3 dB for the right ear (p = 0.0003) and 2 dB for the left ear (p =  0.0009). Speech discrimination scores dropped with an average annual rate of 1.3 and 0.34 % in the right and left ear, respectively. Patients maintained serviceable hearing for an average of 7.6 years (range 2.7-19.3 years). The average annual VS growth was 0.4 mm without any correlation with hearing loss. There was a correlation between patients' age and pure tone threshold increase (p NF2, hearing threshold increases were very slow. In NF2 patients with indolently behaving tumours, serviceable hearing can be maintained for a significant length of time, making conservative management an attractive option. PMID:25294053

Current aspects of hearing loss from occupational and leisure noise  

Directory of Open Access Journals (Sweden)

Full Text Available Hearing loss from occupational and leisure noise numbers amongst the most frequent causes of an acquired sensorineural hearing loss. Here we present a review of up-to-date findings on the pathophysiology of acoustic injury to the inner ear, with special attention being paid to its molecular-biological and genetic aspects. Epidemiological aspects shall also be dealt with, as shall the roles of lacking recovery from occupational noise due to additional exposure by leisure noise and the combined exposure of noise and chemicals. Based on the epidemiological and pathophysiological findings and against the background of published animal-experimental, pre-clinical and clinical findings, the various approaches for prevention, protection and therapeutic intervention with acoustic trauma are discussed. Pharmacological strategies involving anti-oxidative, anti-excitotoxic and anti-apoptotic substances as well as non-pharmacological strategies like "sound conditioning" are given attention. Furthermore, systemic and local substance application as well as the therapy of acute acoustic trauma and chronic hearing problems (including modern therapy forms for comorbidities such as tinnitus shall be delved into.

Predictors of hearing loss in school entrants in a developing country  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Hearing loss is a prevalent and significant disability that impairs functional development and educational attainment of school children in developing countries. Lack of a simple and practical screening protocol often deters routine and systematic hearing screening at school entry. Aim: To identify predictors of hearing loss for a practical screening model in school-aged children. Settings and Design: Community-based, retrospective case-control study of school entrants in an inner city. Methods: Results from the audiologic and non-audiologic examination of 50 hearing impaired children in randomly selected mainstream schools were compared with those of a control group of 150 normal hearing children, matched for age and sex from the same population. The non-audiologic evaluation consisted of medical history, general physical examination, anthropometry, motor skills, intelligence and visual acuity while the audiologic assessment consisted of otoscopy, audiometry and tympanometry. Statistical Analysis: Multiple logistic regression analysis of significant variables derived from univariate analysis incorporating student t-test and chi-square. Results: Besides parental literacy (OR:0.3; 95% CI:0.16-0.68, non-audiologic variables showed no association with hearing loss. In contrast, most audiologic indicators, enlarged nasal turbinate (OR:3.3; 95% CI:0.98-11.31, debris or foreign bodies in the ear canal (OR:5.4; 95% CI:1.0-36.03, impacted cerumen (OR:6.2; 95% CI:2.12-14.33, dull tympanic membrane (OR:2.2; 95% CI:1.10-4.46, perforated ear drum (OR:24.3; 95% CI:2.93-1100.17 and otitis media with effusion OME (OR:14.2; 95% CI:6.22-33.09, were associated with hearing loss. However, only parental literacy (OR:0.3; 95% CI:0.16-0.69, impacted cerumen (OR:4.0; 95% CI:1.66-9.43 and OME (OR:11.0; 95% CI:4.74-25.62 emerged as predictors. Conclusion: Selective screening based on the identification of impacted cerumen and OME will facilitate the detection of a significant proportion of hearing impaired school entrants.

Effects of hearing loss on the subcortical representation of speech cues  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Individuals with sensorineural hearing loss often report frustration with speech being loud but not clear, especially in background noise. Despite advanced digital technology, hearing aid users may resort to removing their hearing aids in noisy environments due to the perception of excessive loudness. In an animal model, sensorineural hearing loss results in greater auditory nerve coding of the stimulus envelope, leading to a relative deficit of stimulus fine structure. Based on the hypothesi...

Single-sided deafness & directional hearing: contribution of spectral cues and high-frequency hearing loss in the hearing ear  

Directory of Open Access Journals (Sweden)

Full Text Available Direction-specific interactions of sound waves with the head, torso and pinna provide unique spectral-shape cues that are used for the localization of sounds in the vertical plane, whereas horizontal sound localization is based primarily on the processing of binaural acoustic differences in arrival time (interaural time differences, or ITDs and sound level (interaural level differences, or ILDs. Because the binaural sound-localization cues are absent in listeners with total single-sided deafness (SSD, their ability to localize sound is heavily impaired. However, some studies have reported that SSD listeners are able, to some extent, to localize sound sources in azimuth, although the underlying mechanisms used for localization are unclear. To investigate whether SSD listeners rely on monaural pinna-induced spectral-shape cues of their hearing ear for directional hearing, we investigated localization performance for low-pass filtered (LP, 3 kHz and broadband (BB, 0.5 – 20 kHz noises in the two-dimensional frontal hemifield. We tested whether localization performance of SSD listeners further deteriorated when the pinna cavities of their hearing ear were filled with a mold that disrupted their spectral-shape cues. To remove the potential use of perceived sound level as an invalid azimuth cue, we randomly varied stimulus presentation levels over a broad range (45-65 dB SPL. Several listeners with SSD could localize HP and BB sound sources in the horizontal plane, but inter-subject variability was considerable. Localization performance of these listeners strongly reduced after diminishing of their spectral pinna-cues. We further show that inter-subject variability of SSD can be explained to a large extent by the severity of high-frequency hearing loss in their hearing ear.

Chronic noise exposure, high-frequency hearing loss, and hypertension among automotive assembly workers.  

Science.gov (United States)

The prevalence of hypertension and mean blood pressure was studied in 150 white men and 119 black men exposed to industrial noise of 85 dBA or greater for a minimum of 5 years. Mean decibel loss at 4000 Hz was 28.3 among the black workers and 45.3 among the white workers. 31.9% of the black men and 22.0% of the white men had hypertension, defined as diastolic blood pressure greater than 90 mm Hg and/or currently taking hypertensive medication. After controlling for several potential confounding factors, hearing loss at 4000 Hz and years worked in high-noise departments were significantly associated with mean blood pressure and hypertension among the black workers. No correlation between mean blood pressure or the presence of hypertension and hearing loss at 4000 Hz or years worked in high-noise departments was found among the white workers. PMID:2401922

Relations between cochlear histopathology and hearing loss in experimental cochlear implantation.  

Science.gov (United States)

This study reviews the cochlear histology from four hearing preservation cochlear implantation experiments conducted on 73 guinea pigs from our institution, and relates histopathological findings to residual hearing. All guinea pigs had normal hearing prior to surgery and underwent cochlear implantation via a cochleostomy with a silastic-platinum dummy electrode. Pure tone auditory brainstem response (ABR) thresholds from 2 to 32 kHz were recorded prior to surgery, and at one and four weeks postoperatively. The cochleae were then fixed in paraformaldehyde, decalcified, paraffin embedded, and mid-modiolar sections were prepared. The treatment groups were as follows: 1) Systemic dexamethasone, 0.2 mg/kg administered 1 h before implantation, 2) Local dexamethasone, 2% applied topically to the round window for 30 min prior to cochlear implantation, 3) Local n-acetyl cysteine, 200 ?g applied topically to the round window for 30 min prior to implantation, 4) inoculation to keyhole-limpet hemocyanin (KLH) prior to implantation, and 5) untreated controls. There was a significant correlation between the extent of the tissue reaction in the cochlea and the presence of foreign body giant cells (FBGCs), new bone formation and injury to the osseous spiral lamina (OSL). The extent of the tissue response, as a percentage of the area of the scala tympani, limited the best hearing that was observed four weeks after cochlear implantation. Poorer hearing at four weeks correlated with a more extensive tissue response, lower outer hair cell (OHC) counts and OSL injury in the basal turn. Progressive hearing loss was also correlated with the extent of tissue response. Hearing at 2 kHz, which corresponds to the region of the second cochlear turn, did not correspond with loco-regional inner hair cell (IHC), OHC or SGC counts. We conclude that cochlear injury is associated with poorer hearing early after implantation. The tissue response is related to indices of cochlear inflammation and injury. An extensive tissue response limits hearing at four weeks, and correlates with progressive hearing loss. These latter effects may be due to inflammation, but would also be consistent with interference of cochlear mechanics. PMID:23396095

Glycinergic synaptic transmission in the cochlear nucleus of mice with normal hearing and age-related hearing loss.  

Science.gov (United States)

The principal inhibitory neurotransmitter in the mammalian cochlear nucleus (CN) is glycine. During age-related hearing loss (AHL), glycinergic inhibition becomes weaker in CN. However, it is unclear what aspects of glycinergic transmission are responsible for weaker inhibition with AHL. We examined glycinergic transmission onto bushy cells of the anteroventral CN in normal-hearing CBA/CaJ mice and in DBA/2J mice, a strain that exhibits an early onset AHL. Glycinergic synaptic transmission was examined in brain slices of mice at 10-15 postnatal days old, 20-35 days old, and at 6-7 mo old. Spontaneous inhibitory postsynaptic current (sIPSC) event frequency and amplitude were the same among all three ages in both strains of mice. However, the amplitudes of IPSCs evoked (eIPSC) from stimulating the dorsal CN were smaller, and the failure rate was higher, with increasing age due to decreased quantal content in both mouse strains, independent of hearing status. The coefficient of variation of the eIPSC amplitude also increased with age. The decay time constant (?) of sIPSCs and eIPSCs were constant in CBA/CaJ mice at all ages, but were significantly slower in DBA/2J mice at postnatal days 20-35, following the onset of AHL, and not at earlier or later ages. Our results suggest that glycinergic inhibition at the synapses onto bushy cells becomes weaker and less reliable with age through changes in release. However, the hearing loss in DBA/2J mice is accompanied by a transiently enhanced inhibition, which could disrupt the balance of excitation and inhibition. PMID:23904491

Evidence for digenic inheritance of nonsyndromic hereditary hearing loss in a Swedish family.  

Science.gov (United States)

We investigated a Swedish family with nonsyndromic progressive bilateral sensorineural hearing loss. Thirteen candidate loci for autosomal dominant nonsyndromic hearing loss were tested for linkage in this family. We found significant LOD scores (>3) for markers at candidate locus DFNA12 (11q22-q24) and suggestive LOD scores (>2) for markers at locus DFNA2 (1p32). Our results for markers on chromosome 11 narrowed down the candidate region for the DFNA12 locus. A detailed analysis of the phenotypes and haplotypes shared by the affected individuals supported the notion that two genes segregated together with hearing impairment in the family. Severely affected family members had haplotypes linked to the disease allele on both chromosomes 1 and 11, whereas individuals with milder hearing loss had haplotypes linked to the disease allele on either chromosome 1 or chromosome 11. These observations suggest an additive effect of two genes, each gene resulting in a mild and sometimes undiagnosed phenotype, but both together resulting in a more severe phenotype. PMID:9718342

Role of macrophage migration inhibitory factor in age-related hearing loss.  

Science.gov (United States)

Hearing loss related to aging is the most common sensory disorder among elderly individuals. Macrophage migration inhibitory factor (MIF) is a multi-functional molecule. The aim of this study was to identify the role of MIF in the inner ear. MIF-deficient mice (MIF(-/-) mice) of BALB/c background and wild-type BALB/c mice were used in this study. Expression of MIF protein in the inner ear was examined by immunohistochemistry in wild-type mice (WT). The hearing function was assessed by the click-evoked auditory brainstem response in both MIF(-/-) mice and WT at 1, 3, 6, 9, 12, and 18months of age. Morphological examination of the cochlea was also performed using scanning electron microscopy and light microscopy. MIF was observed in the spiral ligament, stria vascularis, Reissner's membrane, spiral ganglion cells (SGCs), saccular macula, and membranous labyrinth. The MIF(-/-) mice had a significant hearing loss as compared with the WT at 9, 12, and 18months of age. In the MIF(-/-) mice, scanning electron microscopy showed that the outer cochlear hair cells were affected, but that the inner cochlear hair cells were relatively well preserved. The number of SGCs was lower in the MIF(-/-) mice. MIF was strongly expressed in the mouse inner ear. Older MIF(-/-) mice showed accelerated age-related hearing loss and morphological inner ear abnormalities. These findings suggest that MIF plays an important role in the inner ear of mice.

Frequency of Sensory Neural Hearing Loss in Major Beta-Thalassemias in Southern Iran  

Directory of Open Access Journals (Sweden)

Full Text Available Objective:The thalassemias are among the most common genetic disorders worldwide, occurring more frequently in the Mediterranean region. The aim of this study was to determined frequency of sensory-neural hearing loss in major ß- thalassemias transfusion dependent patients in south of Iran. Methods:A cross sectional study on 308 cases of major beta-thalassemia patients referring to Thalassemia Center of Shiraz University of Medical Sciences between 2006-2007 years. The diagnosis of ß- thalassemia major was based on clinical history, complete blood count and hemoglobine electrophoresis. Clinical data such as serum ferritin level, deferoxamine (DFO dose, mean daily doses of DFO (mg/kg and audiometric variables was recorded. Findings:Out of 308 cases, 283 (96.5% had normal hearing and 10 (3.5% sensorineural hearing loss. There was no statically significant difference between two groups regarding mean age, weight, age at the first blood transfusion, age at the first DFO infusion. Conclusion:We found the lowest incidence of sensorineural hearing loss in a large population of patients suffered from major thalassemia who received DFO. We show that DFO is not ototoxic at a low dose. When considering all related literature, as a whole there has been much critical misrepresentation about DFO ototoxicity.

We used a force platform, AccuSway Plus, where the tests were conducted under the experimental conditions: open base, eyes open (OBEO; open base, eyes closed (OBEC; closed base, eyes open (CBEO; closed base, eyes closed (CBEC. The body sway velocity (V of the center of pressure, the displacement in the anteroposterior direction (COPap and mediolateral (COPml of the center of pressure were the parameters to evaluate the postural control. For statistical analysis we used the nonparametric Mann–Whitney U test, with a significance level of 5%.Results: In comparisons of variables between the groups, the experimental group outperformed by at least 75% of the control group values. In terms of global trends, the experimental group shows higher values of body oscillations in all experimental conditions and variables evaluated. Children with hearing loss had poorer balance performance compared to the group of hearing. The inferential analysis revealed a statistically significant difference in the balance between deaf and hearing children in the OBEC experimental condition in relation to the COPml parameter (P = 0.04. There were no statistically significant differences in comparisons between the sexes when the groups were analyzed separately. The prevalence of unknown etiology showed 58% of cases and congenital rubella in 16%. The discovery of deafness occurred in 70% of children before the age of 3 years.Conclusion: In this study, children with hearing loss had poorer balance performance compared to the group of hearing children. This finding confirms the need to investigate postural control through longitudinal studies to identify the area of sensory deficit causing poor balance performance and promote more specific early interventions.Keywords: postural control, hearing impairment, balance, children, sensory deprivation, early intervention

Risk Factors for Hearing Loss in Patients Treated With Intensity-Modulated Radiotherapy for Head-and-Neck Tumors  

International Nuclear Information System (INIS)

Purpose: Radiotherapy (RT) is a common treatment of head-and-neck carcinoma. The objective of this study was to perform a prospective multivariate assessment of the dose-effect relationship between intensity-modulated RT and hearing loss. Methods and Materials: Pure tone audiometry at 0.250-16 kHz was obtained before and after treatment in 101 patients (202 ears). All patients received full-course intensity-modulated RT (range, 56-70 Gy), with a median cochlear dose of 11.4 Gy (range, 0.2-69.7). Results: Audiometry was performed 1 week before and a median of 9 weeks (range, 1-112) after treatment. The mean hearing deterioration at pure tone average air-conduction 1-2-4 kHz was small (from 28.6 dB HL to 30.1 dB HL). However, individual patients showed clinically significant hearing loss, with 10-dB threshold shift incidences of 13% and 18% at pure tone averages air-conduction 1-2-4 kHz and 8-10-12.5 kHz, respectively. Post-treatment hearing capability was unfavorable in the case of greater inner ear radiation doses (p <0.0001), unfavorable baseline hearing capability (p <0.0001), green-eyed patients (p <0.0001), and older age (p <0.0001). Using multivariate analysis, a prediction of individual hearing capabiltity after treatment was made. Conclusion: RT-induced hearing loss in the mean population is modest. However, clinically significant hearing loss was observed in older patients with green eyes and unfavorable pretreatment hearing. In these patients, the intended raearing. In these patients, the intended radiation dose may be adjusted according to the proposed predictive model, aiming to decrease the risk of ototoxicity.

Effects of auditory training in individuals with high-frequency hearing loss  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english OBJECTIVE: To determine the effects of a formal auditory training program on the behavioral, electrophysiological and subjective aspects of auditory function in individuals with bilateral high-frequency hearing [...] loss. METHOD: A prospective study of seven individuals aged 46 to 57 years with symmetric, moderate high-frequency hearing loss ranging from 3 to 8 kHz was conducted. Evaluations of auditory processing (sound location, verbal and non-verbal sequential memory tests, the speech-in-noise test, the staggered spondaic word test, synthetic sentence identification with competitive ipsilateral and contralateral competitive messages, random gap detection and the standard duration test), auditory brainstem response and long-latency potentials and the administration of the Abbreviated Profile of Hearing Aid Benefit questionnaire were performed in a sound booth before and immediately after formal auditory training. RESULTS: All of the participants demonstrated abnormal pre-training long-latency characteristics (abnormal latency or absence of the P3 component) and these abnormal characteristics were maintained in six of the seven individuals at the post-training evaluation. No significant differences were found between ears in the quantitative analysis of auditory brainstem responses or long-latency potentials. However, the subjects demonstrated improvements on all behavioral tests. For the questionnaire, the difference on the background noise subscale achieved statistical significance. CONCLUSION: Auditory training in adults with high-frequency hearing loss led to improvements in figure-background hearing skills for verbal sounds, temporal ordination and resolution, and communication in noisy environments. Electrophysiological changes were also observed because, after the training, some long latency components that were absent pre-training were observed during the re-evaluation.

Sensori-neural hearing loss in patients treated with irradiation for nasopharyngeal carcinoma  

International Nuclear Information System (INIS)

The present investigation has been carried out to evaluate the sensitivity of the inner ear to irradiation. Cochlear function was tested in a cohort of 22 patients before and 7-84 months after receiving external irradiation for nasopharyngeal carcinoma. The pre-irradiation sensori-neural hearing threshold at 500, 1000, 2000, and 4000 Hz was used as a baseline for the individual patient, and the observed sensori-neural hearing loss (SNHL) was calculated as the difference between pre- and post-irradiation values. The pre-irradiation hearing level or patient age was not correlated with the actual SNHL. In contrast, there was a significant correlation between the total radiation dose to the inner ear and the observed hearing impairment. SNHL was most pronounced in the high frequencies, with values up to 35 dB (4000 Hz) and 25 dB (2000 Hz) in some patients. The latent period for the complication appeared to be 12 months or more. The deleterious effect of irradiation on the hearing should be kept in mind both in treatment planning and in the follow-up after radiotherapy

Outcomes of 3-year-old children with hearing loss and different types of additional disabilities.  

Science.gov (United States)

This research investigated the speech, language, and functional auditory outcomes of 119 3-year-old children with hearing loss and additional disabilities. Outcomes were evaluated using direct assessment and caregiver report. Multiple regressions revealed that type of additional disability and level of maternal education were significant predictors of language outcomes. Poorer outcomes were achieved in a combined group of children with autism, cerebral palsy, and/or developmental delay (DD) (Group A), compared with children with vision or speech output impairments, syndromes not entailing DD, or medical disorders (Group B). Better outcomes were associated with higher levels of maternal education. The association between better language outcomes and earlier cochlear implant switch-on approached significance. Further regression analyses were conducted separately for children with different types of additional disabilities. Level of maternal education was the only significant predictor of outcomes for Group A children, whereas degree of hearing loss was the strongest predictor for children in Group B. The findings highlight the variable impact that different types of additional disabilities can have on language development in children with hearing loss. PMID:24150488

The importance of MRI examination for sudden sensorineural hearing loss patients  

International Nuclear Information System (INIS)

Sudden sensorineural hearing loss is commonly knwon as inner ear disease, although little is known about its cause in most cases. We evaluated 383 patients with sudden sensorineural hearing loss using magnetic resonance imaging (MRI). In 8.1% of the patients, MRI examination revealed some abnormal findings that may be associated with sudden sensorineural hearing loss: acoustic tumor was noted in 1%, abnormality of the vertebral-basilar artery in 1%, and infarction around the brainstem in 0.8%. In these cases, using MRI at an early stage of examination, we can establish the correct diagnosis of and treatment for hearing loss. (author)

Sensoryneural hearing loss with predominantly fall in 2000Hz secondary to connexin 26 gene mutation  

Directory of Open Access Journals (Sweden)

Full Text Available Mutations in the connexin 26 gene result in prelocutive sensorineural hearing loss beginning in childhood, usually severe or profound, although it have been reported slight to moderate hearing loss with some mutations. We present the case of a girl who had a hearing loss with predominantly fall in 2000Hz presenting a biallelic mutation in the connexin 26 gene (M34T/N206S. After a review of the findings of our case and in the medical literature we can conclude that patients with prelocutive sensorineural hearing loss in the frequency 2000 Hz require to rule out mutations in the connexin 26 gene like the M34T.

Full Text Available TEMA: perda auditiva em neonatos. OBJETIVOS: verificar a prevalência de alterações auditivas em neonatos do Hospital São Paulo, observando se há correlação com as variáveis: peso de nascimento, idade gestacional, relação peso e idade gestacional e fatores de risco para deficiência auditiva. MÉTODO: realizou-se uma análise retrospectiva dos prontuários de 1696 recém nascidos, sendo 648 nascidos pré-termo e 1048 a termo. Todas as crianças foram submetidas à avaliação audiológica constituída por pesquisa das emissões otoacústicas transientes e do reflexo cocleopalpebral e medidas de imitância acústica, estabelecendo-se o diagnóstico do tipo e grau de perda. RESULTADOS: a perda auditiva neurossensorial foi identificada em 0,82% das crianças nascidas a termo, e 3,1% das crianças pré-termo (com diferença estatisticamente significante. A perda auditiva condutiva foi a mais freqüente nas duas populações sendo observada em 14,6% das crianças nascidas a termo e 16,3% das crianças pré-termo. Houve suspeita de alterações do sistema auditivo central em 5,8% das crianças pré-termo e 3,3% das crianças a termo. Na população de crianças nascidas a termo, houve correlação significante entre falha na triagem auditiva e os riscos antecedente familiar e síndrome, sendo 37 vezes maior a chance de uma criança com síndrome falhar na triagem e sete vezes maior a chance de falhar na orelha direita quando esta tiver antecedente familiar de perda auditiva. Quanto menor a idade gestacional (BACKGROUND: hearing loss in newborns. Aim: to verify the prevalence of auditory alterations in newborns of Hospital São Paulo (hospital, observing if there are any correlations with the following variables: birth weight, gestational age, relation weight/gestational age and risk factors for hearing loss. METHOD: A retrospective analysis of the hospital records of 1696 newborns; 648 records of preterm infants and 1048 records of infants born at term. All of the infants had been submitted to an auditory evaluation consisting of: Transient Otoacoustic Emissions, investigation of the cochleal-palpebral reflexes and acoustic imittance tests, identifying the type and level of hearing loss. RESULTS: sensorineural hearing loss was identified in .82% of the infants who were born at term and in 3.1% of the preterm infants - with a statistically significant difference. Conductive hearing loss was the most frequent type of hearing loss in both groups, occurring in 14.6% of the term infants and in 16.3% of the preterm infants. Alteration of the central auditory system was considered as a possible diagnosis for 5.8% of the preterm infants and for 3.3% of the term infants. For the group of infants who were born at term, a significant correlation was observed between failure in the hearing screening test and the presence of risk factors such as family history and presence of a syndrome - the child who presented a syndrome had 37 times more chances of failing in the hearing screening test and seven times more chances of failing in the right ear when there was a family history for hearing loss. The lower the gestational age (< 30 weeks and birth weight (< 1500g, the higher the chances of failing in the hearing screening test (3 times more. CONCLUSION: hearing loss had a higher occurrence in preterm infants who remained in the ICU. Gestational age and birth weight were important variables related to the possibility of failure in the hearing screening test. A correlation was observed between the presence of a syndrome and sensorineural hearing loss in infants who were born at term.

[Remote masking as a test of cochlear conductive hearing losses (author's transl)].  

Science.gov (United States)

The authors studied the remote masking (RM) in patients with Menière's disorder during the hearing loss fluctuations produced either by the disorder or by the glycerol test (Klockhoff). The RM was recorded for pulsed tones of 250, 500 and 1 000 Hz; the masker was a continuous narrow-band noise centered at 3 000 Hz, with 305 Hz (2 875-3 180 Hz) bandwidth, delivered at an overall level of 98 dB SPL. The results showed that the RM decreases during the acute phase, i.e. when the hearing loss increases, and, increases if the glycerol tests do not significantly modify the RM value. They seem to confirm the hypothesis that the RM may be due to a mechanical effect in the internal ear and suggest the possibility of using the RM as a test of end-organ rigidity. PMID:687237

A log-normal distribution model of the effect of bacteria and ear fenestration on hearing loss: a Bayesian approach.  

Science.gov (United States)

Chronic ear infection is a potentially life-threatening illness that medical doctors typically treat with ear surgery. Despite the success of this treatment, complications can occur due to bacteria infection. Surgeons believe that this infection causes the patient to have clinically significant hearing damage. In order to understand such complications, surgeons must quantify the effect of bacteria, their toxins and ear surgery on hearing loss. To this end, the other two authors of this paper performed two experiments on guinea pigs to measure hearing thresholds following a bacterial infection and surgery of the inner ear. The response variable in these experiments is hearing thresholds measured in decibels (dB). The problem in analysing such experiments is that the hearing threshold observations often suffer from missing data and censoring mechanisms of various types. Additionally, the distribution of hearing thresholds has heavy tails and is peaked. In order to account for the above statistical issues, we present a Bayesian method with a location-shifted log-normal distribution. The method accounts for the uncertainty in the data collection mechanism and the parameters associated with a location-shifted log-normal distribution. We refer to one of the parameters as the "location-shift" parameter. The Bayesian approach provides a posterior distribution of the location-shift parameter that we compare with values estimated in previously published studies. The immediate goal of our proposed method was to quantify the effects of ear surgery and bacteria infection on hearing loss. Thus, we present the merits of the method in the form of a case study, and report posterior distributions of mean hearing loss, probability of clinically significant hearing loss and relative risk. The results show that surgeon 2, using the surgical procedure "oval window", poses a greater than 40 per cent chance of a 15dB hearing loss regardless of injection of bacteria or not. However, surgeon 1, using the surgical procedure "semicircular canal", does not pose a significantly greater than 40 per cent chance of a 15dB hearing loss unless there is a Pseudomonas aeruginosa-induced infection.

Coronary artery bypass grafting and sensorineural hearing loss, a cohort study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Sudden sensorineural hearing loss is routinely encountered by the otologist. The etiology is varied and often identifiable. One of the relatively less frequent causes is surgery. Apart from being an established entity with otological surgeries, sensorineural hearing loss has also been known to occur after non-otological procedures under general anesthesia. Commonest amongst these procedures is cardiopulmonary bypass, an association that has long been recognized. However, despite the proposition of diverse hypotheses in the past, the pathophysiology remains unclear. Methods The study is a prospective matched cohort study that will be carried out in Aga Khan University Hospital, Karachi, Pakistan. Participants among exposed would include all those patients who would be undergoing coronary artery bypass surgery in the hospital who fall under the criteria for inclusion. Unexposed group would comprise of patients undergoing a non-bypass procedure of similar duration under the same type of anesthesia who meet the selection criteria. Both these groups will undergo audiometric testing at our hospital on three different occasions during the course of this study. Initially before the procedure to test the baseline hearing capacity; then one week after the procedure to assess any changes in hearing ability following the surgery; and finally a third audiogram at six weeks follow-up to assess further changes in any hearing deficits noted during the second phase of testing. Certain variables including the subjects' demographics and those concerning the procedure itself will be noted and used later for risk factors analysis. A detailed past medical and surgical history will also be obtained. Data analysis would include calculation of relative risk and significance of the results, by running the chi-square test. Other statistical tests like Fisher exact test may then be employed to facilitate data interpretation. Continuous scale may then be employed and multivariate linear regression used. Discussion This study is planned to obtain a better understanding of the correlation between sudden sensorineural hearing loss and cardiopulmonary bypass. Being the first major cohort trial in this line of investigation, the project is designed to identify the existence of any significant relationship between cardiopulmonary bypass and sensorineural hearing deficit.

Full Text Available SciELO South Africa | Language: English Abstract in english INTRODUCTION: Many children with hearing impairment present with one or more health-related conditions defined as a co-morbidity in addition to hearing loss. Families and professionals are then faced with various challenges that often complicate the assessment, management and educational placement o [...] f these children. Appropriate holistic intervention is essential for the development and quality of life of the child. This study describes the co-morbidities within the field of occupational therapy, speech therapy and physiotherapy that pre-school children with hearing loss present with at the Centre for Language and Hearing Impaired Children (CLAHIC) and its implications for management. METHOD: A descriptive, retrospective research design was employed. Using a non-probability, purposive sampling strategy the records of 62 children diagnosed with a hearing loss that attended the CLAHIC from 1999 to 2010, were reviewed. RESULTS: The prevalent co-morbidities identified in this study were found mostly within the field of Occupational Therapy and included fine and gross motor delay, visual motor integration disorders and bilateral integration disorders. Further findings indicated that co-morbidities of hearing loss are independent of the degree of the hearing loss. CONCLUSION: The findings suggest that pre-school children with hearing loss, irrespective of the etiology and degree of hearing loss, should be screened for prevalent co-morbidities, such as fine and gross motor difficulties

Training changes processing of speech cues in older adults with hearing loss  

Directory of Open Access Journals (Sweden)

Full Text Available Aging results in a loss of sensory function, and the effects of hearing impairment can be especially devastating due to reduced communication ability. Older adults with hearing loss report that speech, especially in noisy backgrounds, is uncomfortably loud yet unclear. Hearing loss results in an unbalanced neural representation of speech: the slowly-varying envelope is enhanced, dominating representation in the auditory pathway and perceptual salience at the cost of the rapidly-varying fine structure. We hypothesized that older adults with hearing loss can be trained to compensate for these changes in central auditory processing through directed attention to behaviorally-relevant speech sounds. To that end, we evaluated the effects of auditory-cognitive training in older adults (ages 55-79 with normal hearing and hearing loss. After training, the auditory training group with hearing loss experienced a reduction in the neural representation of the speech envelope presented in noise, approaching levels observed in normal hearing older adults. No changes were noted in the control group. Importantly, changes in speech processing were accompanied by improvements in speech perception. Thus, central processing deficits associated with hearing loss may be partially remediated with training, resulting in real-life benefits for everyday communication.

[Sudden sensorineural hearing loss and jugular bulb diverticulum].  

Science.gov (United States)

The relationship between high placed jugular bulb (diverticulum) and inner ear disorder is not well known. Three of 19 patients with sudden sensorineural hearing loss (SSHL) treated in 1995 had right side jugular bulb diverticulum revealed by CT scan and MRA. One of the 3 SSHL cases complicated with delayed endolymphatic hydrops. The exact mechanism of causation of inner ear symptom is not clear, but may partly be due to pressure effects with the jugular fossa encroaching on inner ear structure such as the cochlear aqueduct and vestibular aqueduct, and due to turbular flow in the diverticulum striking the inner ear. It is needed to further study the influence of the diverticulum on the inner ear. PMID:11263142

Age of diagnosis for congenital hearing loss at Universitas Hospital, Bloemfontein  

Scientific Electronic Library Online (English)

Full Text Available SciELO South Africa | Language: English Abstract in english BACKGROUND: Congenital hearing loss affects 3 - 6/1 000 children worldwide. The benefits of early identification of hearing loss and early intervention have been clearly established. There are no previous studies reporting on the age of diagnosis of congenital hearing loss in the Free State province [...] . OBJECTIVES: To determine the age of diagnosis of congenital hearing loss in the Otorhinolaryngology Clinic at Universitas Hospital. Secondary aims included determining age at first visit, as well as the time delay between first visit and diagnosis, and documenting any interventions which took place. METHODS: A retrospective, descriptive study was undertaken, analysing data from 2001 to 2010. RESULTS: A total of 260 cases of congenital hearing loss were analysed. The median age of diagnosis of hearing loss was 44.5 months. The median age of first visit was 40.9 months, and the median delay between first visit and diagnosis was 49 days. CONCLUSIONS: The median age of diagnosis far exceeds national and international benchmarks. This has a profoundly negative impact on the development and outcomes of children with hearing loss. These results have been used to motivate for the expansion of hearing screening and diagnostic services in the province.

Association between idiopathic hearing loss and mitochondrial DNA mutations: A study on 169 hearing-impaired subjects  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Mutations in mitochondrial DNA (mtDNA) have been shown to be an important cause of sensorineural hearing loss (SNHL). In this study, we performed a clinical and genetic analysis of 169 hearing-impaired patients and some of their relatives suffering from idiopathic SNHL, both familial and sporadic. The analysis of four fragments of their mtDNA identified several polymorphisms, the well known pathogenic mutation, A1555G, and some novel mutations in different genes, implying changes in the amino...

Glycinergic synaptic transmission in the cochlear nucleus of mice with normal hearing and age-related hearing loss  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The principal inhibitory neurotransmitter in the mammalian cochlear nucleus (CN) is glycine. During age-related hearing loss (AHL), glycinergic inhibition becomes weaker in CN. However, it is unclear what aspects of glycinergic transmission are responsible for weaker inhibition with AHL. We examined glycinergic transmission onto bushy cells of the anteroventral CN in normal-hearing CBA/CaJ mice and in DBA/2J mice, a strain that exhibits an early onset AHL. Glycinergic synaptic transmission wa...

Effect of low-level laser treatment on cochlea hair-cell recovery after ototoxic hearing loss  

Science.gov (United States)

The primary cause of hearing loss includes damage to cochlear hair cells. Low-level laser therapy (LLLT) has become a popular treatment for damaged nervous systems. Based on the idea that cochlea hair cells and neural cells are from same developmental origin, the effect of LLLT on hearing loss in animal models is evaluated. Hearing loss animal models were established, and the animals were irradiated by 830-nm diode laser once a day for 10 days. Power density of the laser treatment was 900 mW/cm2, and the fluence was 162 to 194 J. The tympanic membrane was evaluated after LLLT. Thresholds of auditory brainstem responses were evaluated before treatment, after gentamicin, and after 10 days of LLLT. Quantitative scanning electron microscopic (SEM) observations were done by counting remaining hair cells. Tympanic membranes were intact at the end of the experiment. No adverse tissue reaction was found. On SEM images, LLLT significantly increased the number of hair cells in middle and basal turns. Hearing was significantly improved by laser irradiation. After LLLT treatment, both the hearing threshold and hair-cell count significantly improved.

The effect of mild-to-moderate hearing loss on auditory and emotion processing networks  

Directory of Open Access Journals (Sweden)

Full Text Available We investigated the impact of hearing loss on emotional processing using task- and rest-based functional magnetic resonance imaging. Two age-matched groups of middle-aged participants were recruited: one with bilateral high-frequency hearing loss (HL and a control group with normal hearing (NH. During the task-based portion of the experiment, participants were instructed to rate affective stimuli from the International Affective Digital Sounds database as pleasant, unpleasant, or neutral. In the resting state experiment, participants were told to fixate on a '+' sign on a screen for five minutes. The results of both the task-based and resting state studies suggest that NH and HL patients differ in their emotional response. Specifically, in the task-based study, we found slower response to affective but not neutral sounds by the HL group compared to the NH group. This was reflected in the brain activation patterns, with the NH group employing the expected limbic and auditory regions including the left amygdala, left parahippocampus, right middle temporal gyrus and left superior temporal gyrus to a greater extent in processing affective stimuli when compared to the HL group. In the resting state study, we observed no significant differences in connectivity of the auditory network between the groups. In the dorsal attention network, HL patients exhibited decreased connectivity between seed regions and left insula and left postcentral gyrus compared to controls. The default mode network was also altered, showing increased connectivity between seeds and left middle frontal gyrus in the HL group. Further targeted analysis revealed increased intrinsic connectivity between the right middle temporal gyrus and the right precentral gyrus. The results from both studies suggest neuronal reorganization as a consequence of hearing loss, most notably in networks responding to emotional sounds.

[An implantable hearing aid for inner ear hearing loss. Short-term implantation of microphone and transducer].  

Science.gov (United States)

A microphone constructed for implantation in the posterior wall of the auditory canal and a piezoelectric transducer serving as the main components of an implantable hearing aid were temporally implanted in five patients during middle ear surgery under local anesthesia. The microphone was positioned beneath the skin of the auditory canal such that it completely covered the microphone membrane. The vibratory element of the transducer was coupled to the malleus in four patients with normal ossicular chains and directly to the stapes in one patient with missing incus. The microphone and transducer were electrically connected with an external battery-driven signal amplifier. Speech material and music were presented in the operation room at a sound level of 65 dB SPL under free-field conditions. The patients had to estimate the quality of speech, music, and their own voice as well as the effects of bone-conducting noises. All patients were able to hear with the system. An intraoperative talk without vision contact was possible without any problems, as was understanding of numerals ("Freiburger Zahlentest"). Perception of music was judged as "clear and undistorted with all broadband component." The estimation was also valid for one patient with a sensorineural hearing loss. One patient declared the music to be "a little of unnatural." Bone-conducted sound was estimated as normal in two patients, better than without an implant in one patient with sensorineural hearing loss, and "somewhat metallic" in another patient. Hearing the own voice was considered "normal" in two cases "monotonous" in one case, and "a little bit roaring" in another case. An amplification factor that can be technically realized in an implantable hearing aid was necessary for one of the patients with sensorineural hearing loss to perceive music at a pleasant volume. On the basis of this study, essential requirements for the construction of a fully implantable hearing aid are fulfilled. PMID:9445860

Clinical analysis of post-irradiation sensorineural hearing loss in patients suffering from nasopharyngeal carcinoma  

International Nuclear Information System (INIS)

Objective: To investigate the incidence of post-irradiation sensorineural hearing loss (SNHL) in patients suffering from nasopharyngeal carcinoma and to evaluate its potentially contributing factors. Methods: Pure tonetest and impedance audiography were carried out in patients suffering from nasopharyngeal carcinoma with a post-irradiation follow-up time over 1 year. Additionally, the test results were combined with clinical data and analyzed retrospectively. Results: The follow-up time of all patients ranged from 12 to 94 months (median 53 months). The incidences of SNHL at low and high frequencies were 8% and 42% respectively. Univariate analysis showed that patient's age and follow-up time affected the incidence of SNHL at high frequencies (t=2.051, P=0.0269; t=2.978, P=0.0011), but sex, preirradiation subjective hearing loss, irradiation dose and chemotherapy including cisplatin had no significance. Multivariate analysis by Binary Logistic Regression revealed that the risk of SNHL was correlated with patient's age and follow-up time (P=0.02; P=0.009). Conclusion: Post-irradiation SNHL at high frequencies in patients suffering from nasopharyngeal carcinoma is more common than that at low frequencies. The independent prognostic factors for development of SNHL at high frequencies are patient's age and follow-up time. But the role of preirradiation hearing level ,irradiation dose and chemotherapy including cisplatin are not conclusive and further research is needed. (nclusive and further research is needed.

Prospective study of inner ear radiation dose and hearing loss in head-and-neck cancer patients  

International Nuclear Information System (INIS)

Purpose: To determine the relationship between the radiation dose to the inner ear and long-term hearing loss. Methods and Materials: Eligible patients included those receiving curative radiotherapy (RT) for head-and-neck cancer. After enrollment, patients underwent three-dimensional conformal RT planning and delivery (180-200 cGy/fraction) appropriate for their disease site and stage. The inner ear was contoured on axial CT planning images. Dose-volume histograms, as well as the mean and maximal dose for each structure, were calculated. Patients underwent pure tone audiometry at baseline (before treatment) and 1, 6, 12, 24, and 36 months after RT. The threshold level (the greater the value, the more hearing loss) in decibels was recorded for 250, 500, 1000, 2000, 4000, and 8000 Hz. For patients receiving predominantly unilateral RT, the contralateral ear served as the de facto control. The differences in threshold level between the ipsilateral and contralateral ears were calculated, and the temporal pattern and dose-response relation of hearing loss were analyzed using statistical methods that take into account the correlation between two ears in the same subject and repeated, sequential measurements of each subject. Results: Of the 40 patients enrolled in this study, 35 qualified for analysis. Four patients who received concurrent chemotherapy and RT were analyzed separately. The 31 unilaterally treated patients received a median dose of 47.4 Gy (range, 14.1-68.8 Gyedian dose of 47.4 Gy (range, 14.1-68.8 Gy) to the ipsilateral inner ear and 4.2 Gy (range, 0.5-31.3 Gy) to the contralateral inner ear. Hearing loss was associated with the radiation dose received by the inner ear (loss of 210dB was observed in ears receiving ?45 Gy) and was most appreciable in the higher frequencies (?2000 Hz). For a 60-year-old patient with no previous hearing loss in either ear, after receiving 45 Gy, the ipsilateral ear, according to our clinical model, would have a 19.3-dB (95% confidence interval [CI], 15.5-23.0) and 5.4-dB (95% CI, 3.5-7.5) hearing decrement compared with the contralateral ear for 8000 Hz and 1000 Hz, respectively. Age and an initial hearing difference within an ear pair also affected hearing loss. The baseline hearing threshold was inversely related to radiation-induced hearing loss. The degree of hearing loss was dependent on the frequency tested, age, baseline hearing, and baseline difference in hearing between a patient's two ears. Conclusion: High-frequency (?2000 Hz) hearing acuity worsens significantly after RT in a dose-dependent fashion. A larger number of patients needs to be studied to validate these results. This knowledge can be applied to create guidelines regarding future dose limits to the auditory apparatus for patients undergoing head-and-neck RT

Age-related hearing loss in sea lions and their scientists  

Science.gov (United States)

Interest in the hearing capabilities of California sea lions (Zalophus californianus) was first stimulated by the echolocation hypothesis and more recently by rising concern about coastal noise pollution. During a series of audiometric tests, we measured the absolute hearing sensitivity of two sea lions and two of their human investigators. Aerial hearing curves for each subject were obtained with a go/no-go procedure and standard psychophysics. Additionally, underwater hearing curves were obtained for the sea lions using the same procedures. Underwater, the older sea lion (22-25 years of age) showed hearing losses relative to the younger sea lion (13-16 years) that ranged from 10 dB at lower frequencies to 50 dB near the upper frequency limit. The older sea lions' hearing losses in air were consistent with those measured underwater. The older human (69 years) tested also showed losses relative to the younger human (22 years). These differences ranged from 15 dB at lower frequencies up to 35 dB at the highest frequency tested. The results obtained in this study document age-related hearing losses in sea lions and humans. The findings are consistent with data on presbycusis in other mammalian species, showing that maximum hearing loss occurs at the highest frequencies.

Are open-fit hearing aids a possible alternative to bone-anchored hearing devices in patients with mild to severe hearing loss? A preliminary trial  

Directory of Open Access Journals (Sweden)

Full Text Available Open-fit hearing aids (OFHAs may be of benefit for some individuals with chronic outer and middle ear conditions for which boneanchored hearing devices (BAHDs are normally recommended. The purpose of this study was to compare performance between OFHAs and BAHDs. A Starkey Destiny 800 OFHA was fit on eight adult BAHD users and speech perception measures in quiet and in background noise were compared under two different test conditions: i BAHD only and ii OFHA only. Equivalent outcome measure performance between these two conditions suggests that the OFHA was able to provide sufficient amplification for mild to moderate degrees of hearing loss (pure-tone averages (PTAs less than 47 dB HL. The improved speech perception performances and increased loudness ratings observed for several of the participants with moderately-severe to severe degrees of hearing loss (PTAs of 47 dB HL or greater in the BAHD only condition suggest that the OFHA did not provide sufficient amplification for these individuals. Therefore, OFHAs may be a successful alternative to the BAHD for individuals with no more than a moderate conductive hearing loss who are unable or unwilling to undergo implant surgery or unable to wear conventional hearing aids due to allergies, irritation, or chronic infection associated with the ear being blocked with a shell or earmold.

The association between low levels of lead in blood and occupational noise-induced hearing loss in steel workers  

International Nuclear Information System (INIS)

As the use of leaded gasoline has ceased in the last decade, background lead exposure has generally been reduced. The aim of this study was to examine the effect of low-level lead exposure on human hearing loss. This study was conducted in a steel plant and 412 workers were recruited from all over the plant. Personal information such as demographics and work history was obtained through a questionnaire. All subjects took part in an audiometric examination of hearing thresholds, for both ears, with air-conducted pure tones at frequencies of 500, 1000, 2000, 3000, 4000, 6000 and 8000 Hz. Subjects' blood samples were collected and analyzed for levels of manganese, copper, zinc, arsenic, cadmium and lead with inductive couple plasma-mass spectrometry. Meanwhile, noise levels in different working zones were determined using a sound level meter with A-weighting network. Only subjects with hearing loss difference of no more than 15 dB between both ears and had no congenital abnormalities were included in further data analysis. Lead was the only metal in blood found significantly correlated with hearing loss for most tested sound frequencies (p < 0.05 to p < 0.0001). After adjustment for age and noise level, the logistic regression model analysis indicated that elevated blood lead over 7 ?g/dL was significantly associated with hearing loss at the sound frequencies of 3000 through 8000 Hz with odds ratios raging from 3.06 to 6.26 (p < 0.05 ? p < 0.005). We concluded that el0.05 ? p < 0.005). We concluded that elevated blood lead at level below 10 ?g/dL might enhance the noise-induced hearing loss. Future research needs to further explore the detailed mechanism.

Connexin26 (GJB2) deficiency reduces active cochlear amplification leading to late-onset hearing loss.  

Science.gov (United States)

Connexin26 (Cx26, GJB2) mutations account for >50% of nonsyndromic hearing loss. The deafness is not always congenital. A large group of these patients (?30%) demonstrate a late-onset hearing loss, starting in childhood. They have normal hearing early in life and are therefore good candidates for applying protective and therapeutic interventions. However, the underlying deafness mechanism is unclear. In this study, we used a time-controlled, inducible gene knockout technique to knockout Cx26 expression in the cochlea after birth. We found that deletion of Cx26 after postnatal day 5 (P5) in mice could lead to late-onset hearing loss. Similar to clinical observations, the mice demonstrated progressive, mild to moderate hearing loss. The hearing loss initiated at high frequencies and then extended to the middle- and low-frequency range. The cochlea showed normal development and had no apparent hair cell loss. However, distortion product otoacoustic emission (DPOAE) was reduced. The reduction was also progressive and large at high-frequencies. Consistent with DPOAE reduction, we found that outer hair cell electromotility-associated nonlinear capacitance was shifted to the right and the slope of voltage dependence was reduced. The endocochlear potential was reduced in Cx26 conditional knockout (cKO) mice but the reduction was not associated with progressive hearing loss. These data suggest that Cx26 deficiency may impair active cochlear amplification leading to late-onset hearing loss. Our study also helps develop newer protective and therapeutic interventions to this common nonsyndromic hearing loss. PMID:25451287

Is sensorineural hearing loss a possible side effect of nasopharyngeal and parotid irradiation? A systematic review of the literature  

International Nuclear Information System (INIS)

Background and purpose: Little has been published about permanent hearing loss due to radiotherapy, thus making it a rather unknown phenomenon. Therefore, we performed a study of the literature over the last 20 years. Materials and methods: Sixteen relevant clinical studies were found, reporting mostly on nasopharyngeal or parotid gland treatments. Hearing loss was measured using a pure tone audiogram. Studies were assessed using a simple scoring list. Nine studies were used for further analysis. Data on the pure tone audiogram were pooled. Results: Results showed that, especially in the higher frequencies (?4 kHz), loss can be measured. When data were pooled, in 42±3% of the patients a hearing loss was found of 10 dB or more at 4 kHz. Averaged over all measured frequencies the effect is less prominent but still statistically significant (18±2%). No significant difference between nasopharyngeal and parotid gland treatment was found (P<0.05). Conclusion: Only a few studies, mostly concerning small patient numbers, have investigated hearing damage due to radiotherapy. So far there has been no consensus on the subject. However, in this systematic review we found a significant effect. Dose to the inner ear therefore deserves more attention, especially in dose escalation studies and inverse planning

Acute sensorineural hearing loss and severe otalgia due to scrub typhus  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi. Case presentations We encountered a patient with sensorineural hearing loss complicating scrub typhus, and three patients with scrub typhus who complained of otalgia, which was sudden onset, severe, paroxysmal, intermittent yet persistent pain lasting for several seconds, appeared within 1 week after the onset of fever and rash. The acute sensorineural hearing loss and otalgia were resolved after antibiotic administration. Conclusion When patients in endemic areas present with fever and rash and have sensorineural hearing loss or otalgia without otoscopic abnormalities, clinicians should suspect scrub typhus and consider empirical antibiotic therapy.

Age-related and noise-induced hearing losses in humans are multifactorial, with contributions from, and potential interactions among, numerous variables that can shape final outcome. A recent retrospective clinical study suggests an age-noise interaction that exacerbates age-related hearing loss in previously noise-damaged ears (Gates et al., 2000). Here, we address the issue in an animal model by comparing noise-induced and age-related hearing loss (NIHL; AHL) in groups of CBA/CaJ mice expos...

Spread of masking in normal subjects and in subjects with high-frequency hearing loss.  

Science.gov (United States)

Upward spread of masking and remote masking were investigated in 4 subjects with closely matched high-frequency hearing losses. Masked thresholds in the presence of a high-frequency or a low-frequency bandpass noise were obtained using an adaptive-threshold procedure. 'Abnormal' upward spread of masking existed for the impaired subjects at some test frequencies when compared to the masking predicted on the basis of normal masking results and hearing-impaired quiet thresholds. Remote masking thresholds were usually shifted to the same absolute levels for normal and hearing-impaired subjects. These results demonstrate that speech reception in noise for listeners with high-frequency hearing loss could be affected by spread of masking and levels of hearing loss. PMID:3707439

Acrylonitrile potentiates hearing loss and cochlear damage induced by moderate noise exposure in rats  

International Nuclear Information System (INIS)

The diversity of chemical and drugs that can potentiate noise-induced hearing loss (NIHL) has impeded efforts to predict such interactions. We have hypothesized that chemical contaminants that disrupt intrinsic antioxidant defenses hold significant risk for potentiating NIHL. If this is true, then acrylonitrile (ACN) would be expected to potentiate NIHL. ACN, one of the 50 most commonly used chemicals in the United States, is metabolized via two pathways that are likely to disrupt intrinsic reactive oxygen species (ROS) buffering systems: (1) it conjugates glutathione, depleting this important antioxidant rapidly; (2) a second pathway involves the formation of cyanide, which can inhibit superoxide dismutase. We hypothesized that moderate noise exposure, that does not produce permanent hearing loss by itself, could initiate oxidative stress and that ACN could render the inner ear more sensitive to noise by disrupting intrinsic antioxidant defenses. Temporary and persistent effects of ACN alone (50 mg/kg, sc 5 days), noise alone (95 or 97 dB octave band noise, 4 h/day for 5 days), or ACN in combination with noise were determined using distortion product otoacoustic emissions (DPOAEs) and compound action potential (CAP) amplitudes. Histopathological damage to hair cells resulting from these treatments was also investigated using surface preparations of the organ of Corti. Individually, neither ACN nor noise exposures caused any permanent hearing or hair cell loss; only aermanent hearing or hair cell loss; only a reversible temporary threshold shift was measured in noise-exposed animals. However, when given in combination, ACN and noise induced permanent threshold shifts (13-16 dB between 7 and 40 kHz) and a decrease in DPOAE amplitudes (up to 25 dB at 19 kHz), as well as significant outer hair cell (OHC) loss (up to 20% in the first row between 13 and 47 kHz). This investigation demonstrates that ACN can potentiate NIHL at noise levels that are realistic in terms of human exposure, and that the OHCs are the main target of toxicity. While the exact mechanism is unknown, the results are consistent with the hypothesis of ROS involvement in NIHL at moderate levels

MÉTODOS: Foram avaliados 57 pacientes, com idades entre 20 e 59 anos (30 home [...] ns e 27 mulheres), que realizaram anamnese, avaliação otorrinolaringológica, avaliação audiológica básica e triagem do processamento auditivo, com o teste Dicótico de Dígitos. Os sujeitos foram alocados nos grupos G1 (audição normal), G2 (perda auditiva leve) e G3 (perda moderada). Foi realizada análise estatística apropriada e o nível de significância adotado foi de 5%. RESULTADOS: Observou-se presença significativa de homens no grupo com perda auditiva. Não foram encontradas diferenças significativas no desempenho do referido teste entre os grupos. Porém, no grupo controle, foram observados piores desempenhos, quando comparados com o critério de normalidade previsto para adultos jovens brasileiros. A média do limiar de detecção de gaps, da amostra geral, foi de 8,2 ms, em ambas as orelhas, e a média das porcentagens de acertos foi de 49,7% para a orelha direita (OD) e de 50,6% para a orelha esquerda (OE). CONCLUSÃO: A habilidade de resolução temporal avaliada pelo teste GIN não sofre influência da perda auditiva sensorioneural de graus leve e moderado, tanto nos limiares de detecção de gaps quanto na porcentagem de acertos, em ambas as orelhas. Abstract in english PURPOSE: To evaluate temporal resolution in adults with mild and moderate sensorineural hearing loss using the Gaps in Noise (GIN) test to determine whether these losses affect the test performance. METHODS: Fifty-seven patients between 20 and 59 years of age (30 men and 27 women) were evaluated; th [...] ese patients had a complete medical history taken and underwent ENT examination, basic audiological evaluation, and auditory screening via the dichotic digits test. The subjects were divided into three groups: G1 (normal hearing), G2 (mild hearing loss), and G3 (moderate hearing loss). The appropriate statistical analysis was performed, and the adopted level of significance was 5%. RESULTS: A significant proportion of men was observed in the group with hearing loss. There were no significant differences in test performance between the groups. However, the control group's performance was worse than the normality criteria set for young Brazilian adults. The mean gap detection threshold for the total sample was 8.2 ms in both ears, and the mean percentage of correct responses was 49.7% for the right ear (RE) and 50.6% for the left ear (LE). CONCLUSION: The temporal resolution evaluated by the GIN test was not influenced by mild-to-moderate sensorineural hearing loss either in the gap detection thresholds or in the percentage of correct responses for both ears.

Targeted massive parallel sequencing: the effective detection of novel causative mutations associated with hearing loss in small families  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Hereditary hearing loss is one of the most common heterogeneous disorders, and genetic variants that can cause hearing loss have been identified in over sixty genes. Most of these hearing loss genes have been detected using classical genetic methods, typically starting with linkage analysis in large families with hereditary hearing loss. However, these classical strategies are not well suited for mutation analysis in smaller families who have insufficient genetic information. Methods Eighty known hearing loss genes were selected and simultaneously sequenced by targeted next-generation sequencing (NGS in 8 Korean families with autosomal dominant non-syndromic sensorineural hearing loss. Results Five mutations in known hearing loss genes, including 1 nonsense and 4 missense mutations, were identified in 5 different genes (ACTG1, MYO1F, DIAPH1, POU4F3 and EYA4, and the genotypes for these mutations were consistent with the autosomal dominant inheritance pattern of hearing loss in each family. No mutational hot-spots were revealed in these Korean families. Conclusion Targeted NGS allowed for the detection of pathogenic mutations in affected individuals who were not candidates for classical genetic studies. This report is the first documenting the effective use of an NGS technique to detect pathogenic mutations that underlie hearing loss in an East Asian population. Using this NGS technique to establish a database of common mutations in Korean patients with hearing loss and further data accumulation will contribute to the early diagnosis and fundamental therapies for hereditary hearing loss.

The consequences of noise-induced hearing loss on dairy farm communities in New Zealand.  

Science.gov (United States)

The objective of this study was to investigate how noise-induced hearing loss (NIHL) or noise injury (NI) affects individuals and others of dairy farm communities in New Zealand. Using "grab" or opportunistic sampling at DairyNZ discussion groups and a recreational function, a survey questionnaire was completed by 74 participants from two dairy farming communities in New Zealand. Self-reported hearing difficulties were highlighted by 48% (42) of the 74 participants. The effects of NI on individuals and others included communication difficulties leading to the development of coping strategies, social isolation; decreased employment opportunities, loss of productivity, and increased effort and adjustments by family and work colleagues. Frustration, anxiety, stress, resentment, depression, and fatigue are also negative consequences that may contribute to a loss of quality of life and contribute to further health costs. Increased lateness, absenteeism, sickness and other behavioral aspects were not expressed as normal issues in the workplace, as the majority of the individuals are/were self-employed or working in a family business. This study shows that each year in New Zealand NI results in significant negative social, psychological, and economic consequences for those individuals affected, along with their families, friends, and work colleagues.

Forward- and simultaneous-masked thresholds in bandlimited maskers in subjects with normal hearing and cochlear hearing loss.  

Science.gov (United States)

Forward- and simultaneous-masked thresholds were measured at 0.5 and 2.0 kHz in bandpass maskers as a function of masker bandwidth and in a broadband masker with the goal of estimating psychophysical suppression. Suppression was operationally defined in two ways: (1) as a change in forward-masked threshold as a function of masker bandwidth, and (2) as a change in effective masker level with increased masker bandwidth, taking into account the nonlinear growth of forward masking. Subjects were younger adults with normal hearing and older adults with cochlear hearing loss. Thresholds decreased as a function of masker bandwidth in forward masking, which was attributed to effects of suppression; thresholds remained constant or increased slightly with increasing masker bandwidth in simultaneous masking. For subjects with normal hearing, slightly larger estimates of suppression were obtained at 2.0 kHz rather than at 0.5 kHz. For hearing-impaired subjects, suppression was reduced in regions of hearing loss. The magnitude of suppression was strongly correlated with the absolute threshold at the signal frequency, but did not vary with thresholds at frequencies remote from the signal. The results suggest that measuring forward-masked thresholds in bandlimited and broadband maskers may be an efficient psychophysical method for estimating suppression. PMID:11519573

Teachers' perceptions of the inclusion of children with hearing loss in general education settings.  

Science.gov (United States)

A questionnaire was used to document the attitudes of 63 classroom teachers in Ottawa, Canada, toward inclusive education for students with hearing loss. The objective was to determine whether teachers had the attitudes, knowledge, and teaching skills proposed to underlie the effective inclusion of these students in regular classrooms. It was found that the teachers had favorable attitudes toward inclusion for students with hearing loss, felt confident in their ability to teach them, and were knowledgeable about the effects of hearing loss on language and learning. They also clearly indicated that their teacher education programs had insufficiently prepared them to teach these students effectively. The results highlight the need for increased emphasis on the unique educational requirements of students with hearing loss in teacher education programs, and for the provision of appropriate supports for both teachers and students to promote successful inclusion.

Prevalence of childhood hearing loss. The Hispanic Health and Nutrition Examination Survey and the National Health and Nutrition Examination Survey II.  

Science.gov (United States)

Comparative analysis of the epidemiology of childhood hearing loss was undertaken among African-American, Hispanic-American, and non-Hispanic white children. Audiometric data on children aged 6-19 years were obtained from 688 African Americans, 330 Cuban Americans, 2,602 Mexican Americans, 1,025 Puerto Ricans, and 3,243 non-Hispanic whites who participated in either the National Health and Nutrition Examination Survey II, 1976-1980, or the Hispanic Health and Nutrition Examination Survey, 1982-1984. Hearing loss was defined as a pure-tone decibel hearing threshold level (averaged over 500, 1,000, and 2,000 Hz) greater than 15 in the ear with the best response. The prevalence (per 1,000) of bilateral hearing loss was 17.0 for African-American, 68.3 for Cuban-American, 27.6 for Mexican-American, 57.7 for Puerto Rican, and 15.5 for non-Hispanic white children. Differences in prevalence by ethnicity/race diminished when a more stringent definition of hearing loss (i.e., moderate or greater than 30 dB hearing threshold level) was used. There were no adolescent African-American males aged 16-19 years who had a hearing loss. After adjustment for age, the odds of hearing loss was significantly greater in males than in females only in non-Hispanic whites (odds ratio = 2.2; 95% confidence interval 1.6-3.3). On the basis of 1993 census population estimates in the United States, over 819,000 children aged 6-19 years have some degree of hearing impairment, and over 216,000 of these children have moderate or greater hearing impairment.

Comparison of acute low-tone sensorineural hearing loss versus Meniere's disease by electrocochleography.  

Science.gov (United States)

To clarify the pathogenesis of acute low-tone sensorineural hearing loss (ALHL), we retrospectively compared the electrocochleographic findings from 20 patients with ALHL with those from 58 patients with Meniere's disease (MD) classified into 4 groups (MD1 through MD4) according to their pure tone average. The mean summating potential-action potential ratio in the ALHL group was 0.35 +/- 0.13, which was significantly higher than the control ratio but similar to the ratio seen in the MD1 group (pure tone average < 25 dB hearing level). The mean detection threshold of the cochlear microphonics in the ALHL group was 32.0 +/- 9.4 dB normal hearing level, which was again similar to that seen in the MDI group. Moreover, more than 50% of patients with ALHL had normal cochlear microphonics input-output curves. We therefore conclude that the pathogenesis of ALHL arises from an endolymphatic hydrops with little or no impairment of hair cells that resembles early-stage MD. PMID:15053200

Brain structural and functional alterations in patients with unilateral hearing loss.  

Science.gov (United States)

Alterations of brain structure and functional connectivity have been described in patients with hearing impairments due to distinct pathogenesis; however, the influence of unilateral hearing loss (UHL) on brain morphology and regional brain activity is still not completely understood. In this study, we aim to investigate regional brain structural and functional alterations in patients with UHL. T1-weighted volumetric images and task-free fMRIs were acquired from 14 patients with right-sided UHL (pure tone average ? 40 dB HL) and 19 healthy controls. Hearing ability was assessed by pure tone audiometry. Voxel-based morphometry (VBM) was performed to detect brain regions with changed gray matter volume or white matter volume in UHL. The amplitude of low-frequency fluctuation (ALFF) was calculated to analyze brain activity at the baseline and was compared between two groups. Compared with controls, UHL patients showed decreased gray matter volume in bilateral posterior cingulate gyrus and precuneus, left superior/middle/inferior temporal gyrus, and right parahippocampal gyrus and lingual gyrus. Meanwhile, patients showed significantly decreased ALFF in bilateral precuneus, left inferior parietal lobule, and right inferior frontal gyrus and insula and increased ALFF in right inferior and middle temporal gyrus. These findings suggest that chronic UHL could induce brain morphological changes and is associated with aberrant baseline brain activity. PMID:25093284

Hearing Loss After Radiotherapy for Pediatric Brain Tumors: Effect of Cochlear Dose  

International Nuclear Information System (INIS)

Purpose: To determine the effect of cochlear dose on sensorineural hearing loss in pediatric patients with brain tumor treated by using conformal radiation therapy (CRT). Patients and Methods: We studied 78 pediatric patients (155 ears) with localized brain tumors treated in 1997-2001 who had not received platinum-based chemotherapy and were followed up for at least 48 months. They were evaluated prospectively by means of serial pure-tone audiograms (250 Hz-8 kHz) and/or auditory brainstem response before and every 6 months after CRT. Results: Hearing loss occurred in 14% (11 of 78) of patients and 11% (17 of 155) of cochleae, with onset most often at 3-5 years after CRT. The incidence of hearing loss was low for a cochlear mean dose of 30 Gy or less and increased at greater than 40-45 Gy. Risk was greater at high frequencies (6-8 kHz). In children who tested abnormal for hearing, average hearing thresholds increased from a less than 25 decibel (dB) hearing level (HL) at baseline to a mean of 46 ± 13 (SD) dB HL for high frequencies, 41 ± 7 dB HL for low frequencies, and 38 ± 6 dB HL for intermediate frequencies. Conclusions: Sensorineural hearing loss is a late effect of CRT. In the absence of other factors, including ototoxic chemotherapy, increase in cochlear dose correlates positively with hearing loss in pediatric patients with brain tumor. To minimize the risk of hearing loss for children treated with radiation therapy, a cumulative cochlear dose less than 35 cumulative cochlear dose less than 35 Gy is recommended for patients planned to receive 54-59.4 Gy in 30-33 treatment fractions

Considerations for cochlear implantation of children with sudden, fluctuating hearing loss.  

Science.gov (United States)

The histories of two pediatric patients who received cochlear implants with subsequent partial recovery of hearing in the nonimplanted ear are reviewed. One child had a sudden bilateral hearing loss, presumably secondary to autoimmune ear disease. The other child had a bilateral progressive hearing loss diagnosed as large vestibular aqueduct syndrome (LVAS). The rationale for the timing of the surgical implantation is discussed. Retrospectively, recovery of hearing in the nonimplanted ear suggests the possibility that the implant could have been delayed or eliminated as a treatment option, and that wearable hearing aids may have been appropriate. A number of factors, however, suggest the decision to implant was appropriate. Issues involved in the decision-making process of when to implant are presented and discussed. PMID:16515130

Prevalence of unilateral hearing loss in children: the National Health and Nutrition Examination Survey II and the Hispanic Health and Nutrition Examination Survey.  

Science.gov (United States)

We compared population-based prevalence rates of unilateral hearing loss among African-American, Cuban-American, Mexican-American, Puerto Rican, and non-Hispanic White children 6 to 19 yr of age. The prevalence (per thousand) of overall hearing loss (average decibel HTL >30) ranged from 6.4 in Mexican-Americans to 12.3 in Cuban-Americans. The prevalence of moderate to profound unilateral hearing loss (average decibel HTL >50) ranged from 0.0 in Cuban-Americans to 5.2 in Puerto Ricans. No statistically significant age or gender differences were found within any of the ethnic groups. Among these five ethnic groups, it is estimated that approximately 391,000 school-aged children in the United States have unilateral hearing loss. PMID:9728728

OBJETIVOS: verificar a prevalência de alterações auditivas em neonatos do Hospital São Paulo, observando se há correlação com as variáveis: peso de nascimento, idade gestacional, relação peso e idade gestacional e fatores de risco para deficiência auditiva. MÉTODO: [...] realizou-se uma análise retrospectiva dos prontuários de 1696 recém nascidos, sendo 648 nascidos pré-termo e 1048 a termo. Todas as crianças foram submetidas à avaliação audiológica constituída por pesquisa das emissões otoacústicas transientes e do reflexo cocleopalpebral e medidas de imitância acústica, estabelecendo-se o diagnóstico do tipo e grau de perda. RESULTADOS: a perda auditiva neurossensorial foi identificada em 0,82% das crianças nascidas a termo, e 3,1% das crianças pré-termo (com diferença estatisticamente significante). A perda auditiva condutiva foi a mais freqüente nas duas populações sendo observada em 14,6% das crianças nascidas a termo e 16,3% das crianças pré-termo. Houve suspeita de alterações do sistema auditivo central em 5,8% das crianças pré-termo e 3,3% das crianças a termo. Na população de crianças nascidas a termo, houve correlação significante entre falha na triagem auditiva e os riscos antecedente familiar e síndrome, sendo 37 vezes maior a chance de uma criança com síndrome falhar na triagem e sete vezes maior a chance de falhar na orelha direita quando esta tiver antecedente familiar de perda auditiva. Quanto menor a idade gestacional ( Abstract in english BACKGROUND: hearing loss in newborns. Aim: to verify the prevalence of auditory alterations in newborns of Hospital São Paulo (hospital), observing if there are any correlations with the following variables: birth weight, gestational age, relation weight/gestational age and risk factors for hearing [...] loss. METHOD: A retrospective analysis of the hospital records of 1696 newborns; 648 records of preterm infants and 1048 records of infants born at term. All of the infants had been submitted to an auditory evaluation consisting of: Transient Otoacoustic Emissions, investigation of the cochleal-palpebral reflexes and acoustic imittance tests, identifying the type and level of hearing loss. RESULTS: sensorineural hearing loss was identified in .82% of the infants who were born at term and in 3.1% of the preterm infants - with a statistically significant difference. Conductive hearing loss was the most frequent type of hearing loss in both groups, occurring in 14.6% of the term infants and in 16.3% of the preterm infants. Alteration of the central auditory system was considered as a possible diagnosis for 5.8% of the preterm infants and for 3.3% of the term infants. For the group of infants who were born at term, a significant correlation was observed between failure in the hearing screening test and the presence of risk factors such as family history and presence of a syndrome - the child who presented a syndrome had 37 times more chances of failing in the hearing screening test and seven times more chances of failing in the right ear when there was a family history for hearing loss.

Interaction of click intensity and cochlear hearing loss on auditory brain stem response wave V latency.  

Science.gov (United States)

Auditory brain stem responses (ABRs) to 95, 80, 60, 40, and 30 dB nHL clicks were retrospectively studied from 103 patients (194 ears) with various degrees of cochlear impairment. Hearing loss and sample size were balanced across gender. Results indicate that the slope of the wave V latency versus 4000 Hz hearing loss function doubles as click intensity is decreased from 80 (0.01 msec/dB HL) to 60 nHL (0.02 msec/dB HL). Overall results indicate a slope increase of 0.0004 msec for each decibel decrease in click intensity from 95 to 30 dB nHL. Intersubject variability increased with increased hearing loss and/or decreased stimulus intensity. The effects of hearing loss on wave V latency are minimal, and intersubject variability is less if high-intensity clicks (greater than or equal to 95 dB nHL) are used. No differences in the effects of hearing loss on wave V latency were seen between males and females. Latency corrections for cochlear hearing loss should, therefore, consider stimulus intensity.

Contralateral hearing loss after vestibular schwannoma excision: A rare complication of neurotologic surgery.  

Science.gov (United States)

We report a rare case of contralateral hearing loss after vestibular schwannoma excision in a 48-year-old man who underwent surgery via a suboccipital approach for removal of a nearly 2-cm lesion involving the right cerebellopontine angle. Postoperatively, the patient awoke with bilateral deafness, confirmed by both audiometry and spontaneous otoacoustic emissions. The patient was treated aggressively with high-dose intravenous steroids, vitamins E and C, and oxygen. Over the next several months he had gradual recovery of most of the hearing in his left (unoperated) ear. Contralateral hearing loss may develop after vestibular schwannoma excision; multiple pathophysiologic mechanisms for this occurrence have been proposed. PMID:25606833

Vacuolization and alterations of lysosomal membrane proteins in cochlear marginal cells contribute to hearing loss in neuraminidase 1-deficient mice.  

Science.gov (United States)

The neuraminidase-1 (Neu1) knockout mouse model is a phenocopy of the lysosomal storage disease (LSD) sialidosis, characterized by multisystemic and neuropathic symptoms, including hearing loss. We have characterized the auditory defects in Neu1(-/-) mice and found that hearing loss involves both conductive and sensorineural components. Auditory brainstem response (ABR) thresholds were significantly elevated in Neu1(-/-) mice at P21 (48-55 dB), and hearing loss appeared progressive (53-66 dB at P60). At these ages Neu1(-/-) mice accumulated cerumen in the external ear canal and had a thickened mucosa and inflammation in the middle ear. In cochleae of adult wild-type mice, Neu1 was expressed in several cell types in the stria vascularis, the organ of Corti, and spiral ganglion. Progressive morphological abnormalities such as extensive vacuolization were detected in the Neu1(-/-) cochleae as early as P9. These early morphologic changes in Neu1(-/-) cochleae were associated with oversialylation of several lysosomal associated membrane proteins (Lamps) in the stria vascularis. A marked increase in the expression and apical localization of Lamp-1 in marginal cells of the stria vascularis predicts exacerbation of lysosomal exocytosis into the endolymph. Consequently, the endolymphatic potential in Neu1(-/-) mice was reduced by approximately 20 mV at ages P31-P44, which would cause dysfunction of transduction in sensory hair cells. This study suggests a molecular mechanism that contributes to hearing loss in sialidosis and identifies potential therapeutic targets. PMID:19857571

Independent impacts of age and hearing loss on spatial release in a complex auditory environment  

Directory of Open Access Journals (Sweden)

Full Text Available Listeners in complex auditory environments can benefit from the ability to use a variety of spatial and spectrotemporal cues for sound source segregation. Probing these abilities is an essential part of gaining a more complete understanding of why listeners differ in navigating the auditory environment. Two fundamental processes that can impact the auditory systems of individual listeners are aging and hearing loss. One difficulty with uncovering the independent effects of age and hearing loss on spatial release is the commonly observed phenomenon of age-related hearing loss. In order to reveal the effects of aging on spatial hearing, it is essential to develop testing methods that reduce the influence of hearing loss on the outcomes. The statistical power needed for such testing generally requires a larger number of participants than can easily be tested using traditional behavioral methods. This work describes the development and validation of a rapid method by which listeners can be categorized in terms of their ability to use spatial and spectrotemporal cues to separate competing speech streams. Results show that when age and audibility are not covarying, age alone can be shown to substantially reduce spatial release from masking. These data support the hypothesis that aging, independent of an individual’s hearing threshold, can result in changes in the cortical and/or subcortical structures essential for spatial hearing.

An Evaluation of Sensory Neural Hearing Loss in Thalassaemic Patients Treated with Desferrioxamine and Its Risk Factors  

Directory of Open Access Journals (Sweden)

Full Text Available Back ground: In major thalassaemia patients who need blood transfusion, iron overload is a major therapeutic disadvantage that leads to heart failure which is the major cause of death in such patients. Desferrioxamine (DFO is the most efficient factor for iron chelation, but it carries adverse effects such sensory-neural hearing loss. Methods: The study began in March 2002 and continued untill March 2003, on 160 cases of thalassaemia to determine the incidence of sensory – neural hearing loss and its risk factors in patients who received Desferrioxamine (DFO. All cases underwent audiometric tests. Retrospectively, other needed information were either obtained through interview or extracted from the medical files. Results were analyzed with ANOVA, t-test and Chi-square tests. Results: Seventy-six patients of the total 156 patients showed impairment in PTA (48.7% with 24 of them suffering significant involvement (15.4%. These abnormalities generally affected high frequencies including, 4000 and 8000 Hz. Male gender, increased serum billirubin level and fasting blood sugar were statistically correlated with hearing loss (p.v = 0.038, p.v = 0.38, p.v = 0.002 respectively. There was no significant correlation between hearing loss and other factors. Mean DFO administration in patients, was 29.69 mg/kg/day and mean therapeutic index of DFO was 0.01 mg/kg/day/mg/lit. Both of them were below the critical level (<40mg/kg/day and <0.025mg/kg/day/mg/lit respectively, however hearing loss had developed. Conclusion: Controlling DFO dosage per se does not seem to be enough for decreasing ototoxicity rate. Periodic audiometric tests are highly recommended to detect hearing loss as soon as possible. There are some other factors such as male gender, increased billirubin and FBS, which contribute to DFO ototoxicity. Looking for these risk factors and controlling them, would help identifying susceptible patients and preventing this complication.

Cochlea hair cell rescue after a noise-induced hearing loss using a low level laser therapy (LLLT)  

Science.gov (United States)

Aim: To see the effect of LLLT on noise-induced hearing loss. Methods: Eleven rats were exposed to noise (120 dB, 16 kHz, 6 h) and left ears were irradiated at 60J/cm2, 830 nm laser for 12 days. Right ears were control. Hearing levels were measured at frequencies of 4, 8, 12, 16, 32 kHz before noise exposure and after 12th irradiations. Results: The initial hearing levels were 26.5+/-4.7, 24.5+/-5.0, 24.0+/-5.2, 24.0+/-3.2, 24.5+/-5.5 dB SPL. After noise exposure, thresholds were 63.5+/-15.1, 64+/-16.8, 71.5+/-11.3, 73.5+/-15.6, 67.5+/-14.4 dB SPL in 4, 8, 12, 16, 32 kHz. After 12th irradiation, thresholds of treated ears recovered significantly 21+/-4.2, 20+/-3.5, 24+/-11.9, 24+/-12.9, 21+/-2.2 dB SPL and that of the untreated right ears measured 36.3+/-22.9, 45+/-15.8, 66.3+/-22.9, 50+/-16.8, 43.8+/-21.4 dB SPL. Conclusion: LLLT may promote recovery of hearing after noiseinduced hearing loss.

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese OBJETIVO: caracterizar o perfil de pescadores participantes de uma ação educativa desenvolvida como parte do Programa de Prevenção de Perdas Auditivas. MÉTODO: estudo seccional realizado com 52 pescadores industriais. Realizou-se ações educativas abordando temas pertinentes à audição, como funcionam [...] ento e cuidados. Após a ação, os participantes responderam a um questionário com questões referentes aos conceitos empregados na palestra e às queixas apresentadas, a seguir fizeram o exame de audiometria. RESULTADOS: a idade dos pescadores variou de 24 a 65 anos (média de 42,8 anos). 61,53% das audiometrias estavam alteradas, sendo que 96,8% dos pescadores com alterações auditivas tinham mais de 40 anos. No questionário respondido, 78,84% dos pescadores consideram que o ruído das embarcações é de forte intensidade; 17,31% referiam dificuldades auditivas; 30,77% com dificuldades em compreender fala e 46,15% com zumbido. 76,92% responderam que além da perda auditiva, o zumbido é um dos efeitos relacionados à exposição ao ruído. Todos estes resultados indicam a necessidade de intervenção preventiva individual e coletiva nesta população. O índice de perdas auditivas é um número que chama a atenção, porém, poucos sentem dificuldades auditivas. A ação educativa realizada foi o primeiro passo para a conscientização destes trabalhadores em relação à prevenção dos prejuízos que a exposição ao ruído pode causar à saúde. CONCLUSÕES: houve dependência significante entre o perfil auditivo e a idade dos pescadores, ou seja, a ocorrência de alterações auditivas é significativamente maior a partir de 40 anos de idade. Assim, os pescadores que apresentavam mais de 40 anos de idade tem 18,05 vezes mais alterações auditivas do que os com menos de 40 anos.
