Experimental Pain and Auditory Sensitivity in Overactive Bladder Syndrome: A Symptoms of the Lower Urinary Tract Dysfunction Research Network (LURN) Study.

PURPOSE: The objective of this study was to investigate the presence of nonbladder sensory abnormalities in participants with overactive bladder syndrome (OAB). MATERIALS AND METHODS: Symptoms of Lower Urinary Tract Dysfunction Research Network (LURN) study participants with OAB symptoms and controls were recruited from 6 U.S. tertiary referral centers. Quantitative sensory testing (QST) was performed to determine pressure pain sensitivity at the thumbnail bed and auditory sensitivity. Fixed and mixed effect multivariable linear regressions and Weibull models were used to compare QST responses between groups. Pearson correlations were used to assess the relationship between QST measures. Associations between QST and self-reported symptoms were explored with linear regression. RESULTS: A total of 297 participants were analyzed (191 OAB, 106 controls; 76% white, 51% male). OAB cases were older than controls (57.4 vs 52.2 years, p=0.015). No significant differences in experimental thumbnail (nonbladder) pain or auditory sensitivity were detected between OAB cases and controls. Correlations between pressure and auditory derived metrics were weak to moderate overall for both groups, with some significantly stronger correlations for cases. Exploratory analyses indicated increased pressure pain and auditory sensitivity were modestly associated with greater self-reported bladder pain and pain interference with physical function. CONCLUSIONS: As a group, no significant differences between OAB cases and controls were observed in experimental nonbladder pain or auditory sensitivity during QST. Associations between QST outcomes and clinical pain raise the possibility of centrally mediated sensory amplification in some individuals with OAB.

Longitudinal auditory pathophysiology following mild blast-induced trauma.

Blast-induced hearing difficulties affect thousands of veterans and civilians. The long-term impact of even a mild blast exposure on the central auditory system is hypothesized to contribute to lasting behavioral complaints associated with mild blast traumatic brain injury (bTBI). Although recovery from mild blast has been studied separately over brief or long time windows, few, if any, studies have investigated recovery longitudinally over short-term and longer-term (months) time windows. Specifically, many peripheral measures of auditory function either recover or exhibit subclinical deficits, masking deficits in processing complex, real-world stimuli that may recover differently. Thus, examining the acute time course and pattern of neurophysiological impairment using appropriate stimuli is critical to better understanding and intervening in bTBI-induced auditory system impairments. Here, we compared auditory brainstem response, middle-latency auditory-evoked potentials, and envelope following responses. Stimuli were clicks, tone pips, amplitude-modulated tones in quiet and in noise, and speech-like stimuli (iterated rippled noise pitch contours) in adult male rats subjected to mild blast and sham exposure over the course of 2 mo. We found that blast animals demonstrated drastic threshold increases and auditory transmission deficits immediately after blast exposure, followed by substantial recovery during the window of 7-14 days postblast, although with some deficits remaining even after 2 mo. Challenging conditions and speech-like stimuli can better elucidate mild bTBI-induced auditory deficit during this period. Our results suggest multiphasic recovery and therefore potentially different time windows for treatment, and deficits can be best observed using a small battery of sound stimuli.NEW & NOTEWORTHY Few studies on blast-induced hearing deficits go beyond simple sounds and sparsely track postexposure. Therefore, the recovery arc for potential therapies and real-world listening is poorly understood. Evidence suggested multiple recovery phases over 2 mo postexposure. Hearing thresholds largely recovered within 14 days and partially explained recovery. However, midlatency responses, responses to amplitude modulation in noise, and speech-like pitch sweeps exhibited extended changes, implying persistent central auditory deficits and the importance of subclinical threshold shifts.

Audiological Performance in Children with Inner Ear Malformations Before and After Cochlear Implantation: A Cohort Study of 274 Patients.

BACKGROUND AND OBJECTIVE: Inner ear malformations (IEMs) are common in children with hearing loss. The different types of IEMs form a unique subgroup of cochlear implant (CI) candidates. We aimed to evaluate the auditory perception outcomes of CI in children with different types of IEMs and compare them with CI users without IEMs. METHODS: The study included 274 CI users with and without IEMs as two groups (n = 137, each). Both groups' chronological age at implantation and duration of CI usage was matched (± 8 months). All subjects were evaluated pre-operatively and post-operatively by the Ling's sound test and the auditory perception test battery, which includes the Meaningful Auditory Integration Scale (MAIS), closed-set Pattern Perception Test (PPT) and open-set Sentence Recognition Test (SRT). Besides, children with IEMs were assessed for language development. RESULTS: Progress in the IEMs' group differed according to the type of ear anomaly. CI users with enlarged vestibular aqueduct had the highest scores, while users with common cavity had the lowest. Children with IEMs performed well on the closed-set test while having difficulty with the open-set test. CONCLUSION: Cochlear implantation outcomes are favourable in IEMs' patients with a cochlear nerve visible on magnetic resonance imaging. Our results indicate that it is critical to take the anatomical differences into account during follow-up and rehabilitation programmes. Each CI user should be evaluated according to his or her individual needs.

Vasculitis and the ear: a literature review.

PURPOSE OF REVIEW: Systemic vasculitides as a group of inflammatory disorders of blood vessels may show clinical manifestations in the ear. This article reviews the recent literature about vasculitis of the ear or the cochleovestibular system, focusing on giant-cell arteritis, Takayasu's arteritis, polyarteritis nodosa, Kawasaki disease, microscopic polyangiitis, granulomatosis with polyangiitis (GPA), eosinophilic GPA, systemic lupus erythematosus, Cogan's syndrome and Behçet's disease. RECENT FINDINGS: In patients with vasculitis, hearing impairment is a frequent problem, followed by tinnitus and vertigo. The severity of sensorineural hearing loss can range from mild impairment to deafness. Autoimmune diseases can induce a conductive hearing loss as a result of effusions of the middle ear, the inflammation of the mucosa of the Eustachian tube, or the involvement of the ossicular chain. Vertigo may be caused by the temporary or permanent occlusion of the labyrinthine or the anterior vestibular artery. Middle ear inflammation is frequent in GPA and eosinophilic GPA. SUMMARY: The progressive sensorineural hearing loss in polyarteritis nodosa or Cogan's syndrome patients may be treated by cochlear implantation.

Impact of an intervention to support hearing and vision in dementia: The SENSE-Cog Field Trial.

OBJECTIVES: Hearing, vision, and cognitive impairment commonly co-occur in older adults. Improving sensory function may positively impact outcomes in people with dementia (PwD). We developed a "sensory intervention" (SI) to support hearing and vision in PwD. Here, we report the findings of an international open-label field trial, and nested case series, to explore the impact of the SI on dementia-related outcomes. METHODS: This was a home-based trial conducted in France, England, and Cyprus. Participants were people with mild-to-moderate dementia and hearing and/or vision impairment (n = 19) and their study partners (unpaid carers; n = 19). The "basic" SI included a hearing and vision assessment and provision of glasses and/or hearing aids. A subsample received the "extended" SI with additional weekly visits from a sensory support therapist (SST). Exploratory analyses of dementia-related, health utility and resource utilisation outcomes were performed. RESULTS: Quality of life (QoL) and sensory functional ability improved. Change in QoL exceeded the threshold for a minimum clinically important difference. There was a modest improvement (in absolute terms) post intervention in behavioural disturbance, self-efficacy, and relationship satisfaction. Study partner time assisting instrumental activities of daily living (iADL) and supervision decreased by about 22 and 38 hours per month, respectively, although time for personal ADL support increased. Qualitative data supported effectiveness of the intervention: PwD were more socially engaged, less isolated, less dependent on study partners, and had improved functional ability and communication. CONCLUSIONS: These findings support the need for a definitive randomised controlled trial (RCT) to evaluate the effectiveness of the intervention.

Epidemiology of cerebral palsy in Sumba Island, Indonesia.

AIM: To define the epidemiology, clinical characteristics, and rehabilitation status of children with cerebral palsy (CP) in Sumba Island, Indonesia. METHOD: A community-based key informant method survey among children (aged <18y) with CP was conducted between March and August 2017. Children with suspected CP underwent detailed neurodevelopmental assessment by a multidisciplinary medical team. Socio-demographic characteristics, aetiology, motor type, motor severity, associated impairments, educational, and rehabilitation status were documented. RESULTS: There were 130 children with clinically confirmed CP. The mean age at assessment was 8 years 11 months and 43.8% (n=57) of the children were female. The mean age at CP diagnosis was 6 years 5 months. Of these children, 46.9% (n=61) had post-neonatally acquired CP, most frequently because of vaccine-preventable infectious encephalopathy (73.8%, n=45). In total, 80.8% (n=105) had a predominantly spastic motor type of CP and 83.8% (n=109) were classified in Gross Motor Functional Classification System levels III to V. A total of 77.7% (n=101) had at least one associated impairment (speech 77.5%, intellectual 29.2%, visual 13.8%, hearing 20.0%, and epilepsy 13.5%). And 66.2% (n=86) had never received rehabilitation services. INTERPRETATION: Post-neonatally acquired CP was common in this setting. Addressing preventable post-neonatally acquired risk factors for CP should be a public health priority. Earlier identification and diagnosis of CP would also provide new opportunities for early intervention and targeted rehabilitation services.

Delayed Supratentorial Intracerebral Hemorrhage After Posterior Fossa Acoustic Neuroma Surgery.

A 72-year-old female patient was complaining from gradual loss of hearing in the left ear, left facial palsy with gait imbalance. Neuroimaging showed left cerebellopontine angle extra-axial mass and was diagnosed as acoustic neuroma. She was operated with left retromastoid suboccipital and gross total excision of the tumor was achieved. Early postoperative period was uneventful and brain computed tomographic (CT) scan in the postoperative day 1 showed gross total resection of the tumor without complications, and patient was discharged at the postoperative day 4. In the postoperative day 7, the patient showed decrease level of consciousness and brain CT scan showed a small hematoma in the anterior part of the left temporal lobe, which was evolved to large intraparanchymal hemorrhage with midline shift in postoperative day 9.

Effects of Liberal vs Restrictive Transfusion Thresholds on Survival and Neurocognitive Outcomes in Extremely Low-Birth-Weight Infants: The ETTNO Randomized Clinical Trial.

Importance: Red blood cell transfusions are commonly administered to infants weighing less than 1000 g at birth. Evidence-based transfusion thresholds have not been established. Previous studies have suggested higher rates of cognitive impairment with restrictive transfusion thresholds. Objective: To compare the effect of liberal vs restrictive red blood cell transfusion strategies on death or disability. Design, Setting, and Participants: Randomized clinical trial conducted in 36 level III/IV neonatal intensive care units in Europe among 1013 infants with birth weights of 400 g to 999 g at less than 72 hours after birth; enrollment took place between July 14, 2011, and November 14, 2014, and follow-up was completed by January 15, 2018. Interventions: Infants were randomly assigned to liberal (n = 492) or restrictive (n = 521) red blood cell transfusion thresholds based on infants' postnatal age and current health state. Main Outcome and Measures: The primary outcome, measured at 24 months of corrected age, was death or disability, defined as any of cognitive deficit, cerebral palsy, or severe visual or hearing impairment. Secondary outcome measures included individual components of the primary outcome, complications of prematurity, and growth. Results: Among 1013 patients randomized (median gestational age at birth, 26.3 [interquartile range {IQR}, 24.9-27.6] weeks; 509 [50.2%] females), 928 (91.6%) completed the trial. Among infants in the liberal vs restrictive transfusion thresholds groups, respectively, incidence of any transfusion was 400/492 (81.3%) vs 315/521 (60.5%); median volume transfused was 40 mL (IQR, 16-73 mL) vs 19 mL (IQR, 0-46 mL); and weekly mean hematocrit was 3 percentage points higher with liberal thresholds. Among infants in the liberal vs restrictive thresholds groups, the primary outcome occurred in 200/450 (44.4%) vs 205/478 (42.9%), respectively, for a difference of 1.6% (95% CI, -4.8% to 7.9%; P = .72). Death by 24 months occurred in 38/460 (8.3%) vs 44/491 (9.0%), for a difference of -0.7% (95% CI, -4.3% to 2.9%; P = .70), cognitive deficit was observed in 154/410 (37.6%) vs 148/430 (34.4%), for a difference of 3.2% (95% CI, -3.3% to 9.6%; P = .47), and cerebral palsy occurred in 18/419 (4.3%) vs 25/443 (5.6%), for a difference of -1.3% (95% CI, -4.2% to 1.5%; P = .37), in the liberal vs the restrictive thresholds groups, respectively. In the liberal vs restrictive thresholds groups, necrotizing enterocolitis requiring surgical intervention occurred in 20/492 (4.1%) vs 28/518 (5.4%); bronchopulmonary dysplasia occurred in 130/458 (28.4%) vs 126/485 (26.0%); and treatment for retinopathy of prematurity was required in 41/472 (8.7%) vs 38/492 (7.7%). Growth at follow-up was also not significantly different between groups. Conclusions and Relevance: Among infants with birth weights of less than 1000 g, a strategy of liberal blood transfusions compared with restrictive transfusions did not reduce the likelihood of death or disability at 24 months of corrected age. Trial Registration: ClinicalTrials.gov Identifier: NCT01393496.

The effect of premature ovarian failure on inner ear function.

The aim of this study was to test whether hearing function is impaired in women with premature ovarian failure. Thirty (30) women with premature ovarian failure (POF), 30 women in menopause and 30 healthy controls were recruited in this study. Pure tone audiometric (PTA), transiently evoked otoacoustic emissions (TEOAEs) and distortion product otoacoustic emissions (DPOAEs) of the study participants were analysed. At PTA, 6 and 8 kHz were lower in menopause group compared with both women with POF and controls. At TEOAE 3 and 4 kHz and at DPOAE 1, 2, 4 and 6 kHz were lower in menopause group compared with the controls. At DPOAE 6 kHz was lower in the POF group compared with the controls. Women with POF comparing to menopause group at TEOAE 3, 4 kHz and at DPOAE 4 and 6 kHz were lower in the menopause group. Inner ear function of both women in menopause and women with POF was declined compared to the healthy controls. Clinically, evaluation of hearing status may be considered in women with POF.Impact statementWhat is already known on this subject: Premature ovarian failure (POF) affects 1%-2% of women, and it adversely effects on health status (such as cardiovascular, psychological and cognitive disorders). Previous studies suggested that a lack of oestrogen might play a role in hearing disorders in women. However, we do not know POF's adversely effect on cochlea and hearing.What the results of this study add: The present study demonstrates that lower serum oestrogen has a negative effect hearing in women with POF at DPOAE 6 kHz.What the implications are of these findings for clinical practice and/or further research: The women with POF must be evaluated for hearing status.

[Audiological correlates of age-related manifestations of auditory disorders.]

The aim of the study was a comparative analysis of complaints and audiological findings in patients of the audiological center depending on their age. The results of the examination of 300 firstly consulted patients (random sample) are presented. The group of young patients (19-44 years) included 40 people; middle age (45-59 years) - 62 people; elderly (60-74 years) - 100 people; senile age (75-90 years) - 98 people. The survey included the collection of complaints and anamnesis, ENT checkup, pure tone audiometry, impedancemetry, speech audiometry in headphones to detect the signs of Central Auditory Processing Disorder or in the free sound field to assess the effectiveness of hearing aids. It was found that for early diagnosis of hearing loss and prevention of age-related sensory-cognitive dysfunction, it is advisable to use not only the results of pure tone audiometry, but also the data of speech audiometry, as well as the analysis of subjective complaints. The results of the work indicate the need for hearing screening in the population over 60 years old.

Congenital Cytomegalovirus Infection Alters Olfaction Before Hearing Deterioration In Mice.

In developed countries, cytomegalovirus (CMV)-infected newborns are at high risk of developing sensorineural handicaps such as hearing loss, requiring extensive follow-up. However, early prognostic tools for auditory damage in children are not yet available. In the fetus, CMV infection leads to early olfactory bulb (OB) damage, suggesting that olfaction might represent a valuable prognosis for neurological outcome of this viral infection. Here, we demonstrate that in utero CMV inoculation causes fetal infection and growth retardation in mice of both sexes. It disrupts OB normal development, leading to disproportionate OB cell layers and rapid major olfactory deficits. Olfaction is impaired as early as day 6 after birth in both sexes, long before the emergence of auditory deficits. Olfactometry in males reveals a long-lasting alteration in olfactory perception and discrimination, particularly in binary mixtures of monomolecular odorants. Although sensory inputs to the OB remain unchanged, hallmarks of autophagy are increased in the OB of 3-postnatal week-old mice, leading to local neuroinflammation and loss of neurons expressing tyrosine hydroxylase and calbindin. At the cellular level, we found CMV-infected cells and an increased number of apoptotic cells scattered throughout the OB layers, whereas cell proliferation in the neurogenic subventricular zone was decreased. These cellular observations were long-lasting, persisting up to 16 weeks after birth in both males and females and thus providing a mechanism supporting olfactory loss. Despite obvious differences in neurogenesis between human and mouse, these findings offer new strategies aimed at early detection of neurological dysfunctions caused by congenital infections.SIGNIFICANCE STATEMENT In developed countries, congenital cytomegalovirus (CMV)-infected newborns are at high risk of developing sensory handicaps such as hearing loss, thus requiring prolonged follow-up. In this study, we describe for the first time the functional impact of congenital CMV infection on the olfactory system and its associated sense of smell. We demonstrate that a mouse model of congenital CMV infection shows defects in olfactory bulb (OB) normal development and pronounced olfactory deficits affecting acuity and discrimination of odorants. These major olfactory deficits occur long before the emergence of auditory deficits through the upregulation of OB autophagy inducing local neuroinflammation and altered neuron content. Our findings provide new opportunities for designing olfactory means to monitor the possible neurological outcome during congenital CMV infection.

Is intensity-modulated radiotherapy superior to conventional techniques to prevent late ear complications of nasopharyngeal cancer?

PURPOSE: This study analyzed the late ear complications of radiotherapy for nasopharyngeal cancer (NPC) and compared the conventional and intensity-modulated radiotherapy (2D-RT and IMRT, respectively). METHODS: At 2-21 years after the end of NPC treatment, 104 ears of 52 patients were evaluated with the otoscopic examination, pure tone audiometry test, tympanometry, and subjective complaints by being blinded to the radiotherapy technique. RESULTS: There were no differences in terms of the pathology of the external, middle or inner ear, air and bone-conduction hearing thresholds, and the air-bone (A-B) gap at 500, 1000, 2000, and 4000 Hz, and tympanometry types between 2D-RT and IMRT groups (p > 0.05). There were positive correlations between the values of A500 and A1000 thresholds; gap 500, 4000, and mean cochlear RT dose (p < 0.05). There were positive correlations between the values of A500, A1000, and A4000 thresholds; gap 500, 1000, 2000, 4000, and maximum cochlear RT dose (p < 0.05). CONCLUSION: IMRT was not found to be superior to 2D-RT to prevent RT-induced ear complications. The solution of the middle ear problems must be the goal of the strategies for complications treatment.

Auditory system dysfunction in Brazilian gasoline station workers.

Objective: To examine the auditory system of Brazilian gasoline station workers using an extensive audiological test battery. Design: This was a cross-sectional study. The audiological evaluation included a questionnaire, pure-tone audiometry, acoustic immittance tests, transient-evoked otoacoustic emissions (TEOAEs), distortion product otoacoustic emissions (DPOAEs), auditory brainstem response (ABR) and P300 auditory-evoked potentials. Study sample: A total of 77 Brazilian gasoline station workers were evaluated, and their results were compared with those of 36 participants who were not exposed to chemicals or noise at work. The gasoline station employees worked in 18 different gas stations, and the noise area measurements from all gas stations revealed time-weighted averages below 85 dBA. Results: Of the 77 gasoline station workers evaluated, 67.5% had audiometric results within the normal range, but 59.7% reported difficulties in communication in noisy places. Gasoline station workers showed significantly poorer results than non-exposed control participants in one or more conditions of each of the audiological tests used, except P300. Conclusions: The results suggest that the gasoline station workers have both peripheral and central auditory dysfunctions that could be partly explained by their exposure to gasoline.

Combined effect of non-bacteriolytic antibiotic and inhibition of matrix metalloproteinases prevents brain injury and preserves learning, memory and hearing function in experimental paediatric pneumococcal meningitis.

BACKGROUND: Pneumococcal meningitis is associated with high mortality and morbidity rates. Up to 50% of survivors show neurologic sequelae including hearing loss, cognitive impairments and learning disabilities, being particularly detrimental in affected infants and children where adjuvant therapy with dexamethasone has no proven beneficial effect. We evaluated the effect of concomitantly targeting specific pathophysiological mechanisms responsible for brain damage-i.e. matrix-metalloproteinase (MMP) activity and the exacerbated cerebral inflammation provoked through antibiotic-induced bacterial lysis. Here, we combined adjunctive therapies previously shown to be neuroprotective when used as single adjuvant therapies. METHODS: Eleven-day-old Wistar rats were infected intracisternally with 6.44 ± 2.17 × 103 CFU Streptococcus pneumoniae and randomised for treatment with ceftriaxone combined with (a) single adjuvant therapy with daptomycin (n = 24), (b) single adjuvant therapy with Trocade (n = 24), (c) combined adjuvant therapy (n = 66) consisting of daptomycin and Trocade, or (d) ceftriaxone monotherapy (n = 42). Clinical parameters and inflammatory CSF cytokine levels were determined during acute meningitis. Cortical damage and hippocampal apoptosis were assessed 42 h after infection. Morris water maze and auditory brainstem responses were used to assess neurofunctional outcome 3 weeks after infection. RESULTS: We found significantly reduced apoptosis in the hippocampal subgranular zone in infant rats receiving adjuvant Trocade (p < 0.01) or combined adjuvant therapy (p < 0.001). Cortical necrosis was significantly reduced in rats treated with adjuvant daptomycin (p < 0.05) or combined adjuvant therapy (p < 0.05) compared to ceftriaxone monotherapy. Six hours after treatment initiation, CSF cytokine levels were significantly reduced for TNF-α (p < 0.01), IL-1ß (p < 0.01), IL-6 (p < 0.001) and IL-10 (p < 0.01) in animals receiving combined adjuvant intervention compared to ceftriaxone monotherapy. Importantly, combined adjuvant therapy significantly improved learning and memory performance in infected animals and reduced hearing loss (77.14 dB vs 60.92 dB, p < 0.05) by preserving low frequency hearing capacity, compared to ceftriaxone monotherapy. CONCLUSION: Combined adjuvant therapy with the non-bacteriolytic antibiotic daptomycin and the MMP inhibitor Trocade integrates the neuroprotective effects of both single adjuvants in experimental paediatric pneumococcal meningitis by reducing neuroinflammation and brain damage, thereby improving neurofunctional outcome. This strategy represents a promising therapeutic option to improve the outcome of paediatric patients suffering from pneumococcal meningitis.

Long-term hearing outcomes after gamma knife surgery in patients with vestibular schwannoma with hearing preservation: evaluation in 92 patients with serial audiograms.

The treatment strategy for patients with vestibular schwannoma (VS) is controversial, and data concerning the long-term hearing outcomes > 5 years after gamma knife surgery (GKS) are limited. The long-term hearing outcomes after GKS were evaluated in VS patients with hearing preservation. Ninety-two VS patients with a pure tone average (PTA) ≤ 50 dB were evaluated. The median age was 54 years; the median tumor volume was 1.5 cm3. The tumors were treated with a median margin dose of 12 Gy and a median mean cochlear dose of 4.0 Gy. At the time of GKS, 65 patients retained a PTA of 0-30 dB, and 27 had a PTA of 31-50 dB. The median follow-up period was 106 months. At the final follow-up, 2 (2%) developed tumor progression. During the median audiogram follow-up of 83 months, the PTA was ≤ 30 dB in 22 patients (24%) and 31-50 dB in 27 patients (29%); 43 patients (47%) worsened to a PTA > 50 dB. Hearing preservation rates were 66, 57, and 44% at 3, 5, and 10 years, respectively. In multivariate analysis, the mean cochlear dose (P < 0.001) and pre-GKS PTA (P = 0.045) were significant for hearing preservation. GKS was an effective treatment option for VS patients with a PTA ≤ 50 dB. As a lower cochlear dose and better pre-GKS PTA contributed to long-term hearing preservation, prophylactic GKS before hearing deterioration or tumor growth would be a treatment of choice if patients provided informed consent.

The role of auditory evoked potentials and otoacoustic emissions in early detection of hearing abnormalities in Behçet's disease patients. A case control study.

OBJECTIVES: To determine the types and to assess the role of auditory evoked potentials and otoacoustic emissions in early detection of hearing abnormalities in Behçet's disease (BD) patients. Their correlations with disease activity were also considered. METHODS: Thirty patients with BD and thirty apparently sex- and age-matched healthy volunteers were included in this study. Auditory evaluation included pure tone audiometry (PTA), otoacoustic emissions (TEOAEs, DPOAE), auditory brainstem response test (ABR) and cortical auditory evoked potentials (tone and speech CAEPs) for all patients and control. RESULTS: The highest abnormality of CAEP latencies elicited by (500Hz and 1000 Hz) as well as speech stimuli (da and ga) among our BD patients was delayed P1 and N1 waves at 80 dB with greater bilateral affection, as well as significant differences between patients and controls. All our BD patients had a smaller amplitude of distortion product OAE (DPOAE) and S/N ratio at 1, 2, 4, 6 kHZ compared with controls and the differences were highly statistically significant (p=0.0001). CONCLUSIONS: Being one of the autoimmune inner ear diseases (AIED), BD has a definite hearing impairment, even in the presence of normal hearing sensitivity, as evidenced by PTA. BD patients had a sub-clinical cochlear pathology which was not affected by disease activity or different organ affection. DPOAE (S/N ratio) proved to be a sensitive test in detecting minimal changes in cochlear pathology and the latencies of CAEPs (tone and speech) measures were considered as sensitive indicators (100%) of early detection of hearing impairment in BD patients.

Post hemorrhagic hydrocephalus and neurodevelopmental outcomes in a context of neonatal intraventricular hemorrhage: an institutional experience in 122 preterm children.

BACKGROUND: Intraventricular hemorrhage (IVH) is a frequent complication in extreme and very preterm births. Despite a high risk of death and impaired neurodevelopment, the precise prognosis of infants with IVH remains unclear. The objective of this study was to evaluate the rate and predictive factors of evolution to post hemorrhagic hydrocephalus (PHH) requiring a shunt, in newborns with IVH and to report their neurodevelopmental outcomes at 2 years of age. METHODS: Among all preterm newborns admitted to the department of neonatalogy at Rouen University Hospital, France between January 2000 and December 2013, 122 had an IVH and were included in the study. Newborns with grade 1 IVH according to the Papile classification were excluded. RESULTS: At 2-year, 18% (n = 22) of our IVH cohort required permanent cerebro spinal fluid (CSF) derivation. High IVH grade, low gestational age at birth and increased head circumference were risk factors for PHH. The rate of death of IVH was 36.9% (n = 45). The rate of cerebral palsy was 55.9% (n = 43) in the 77 surviving patients (49.4%). Risk factors for impaired neurodevelopment were high grade IVH and increased head circumference. CONCLUSION: High IVH grade was strongly correlated with death and neurodevelopmental outcome. The impact of an increased head circumference highlights the need for early management. CSF biomarkers and new medical treatments such as antenatal magnesium sulfate have emerged and could predict and improve the prognosis of these newborns with PHH.

Preliminary study of hearing protection and non-impact, blast-induced concussion in US military personnel.

PRIMARY OBJECTIVE: To examine the relationship between hearing protection and non-impact, blast-induced concussion in US military personnel. RESEARCH DESIGN: Retrospective cohort study. METHODS AND PROCEDURES: A total of 501 US service members from the Expeditionary Medical Encounter Database with hearing protection status reported either 'worn' or 'not worn' were eligible for analysis. Clinical records were reviewed for concussion diagnoses. Univariate and multiple logistic regressions were performed. MAIN OUTCOMES AND RESULTS: Overall, 270 (53.9%) service members sustained non-impact, blast-induced concussion and 231 (46.1%) sustained other blast injuries. Only 39.6% (107 of 270) of service members with concussion wore hearing protection at the point of injury compared with 61.0% (141 of 231) of those with other injuries (p < 0.001). After adjusting for covariates, service members wearing hearing protection had significantly lower odds of concussion compared with those not wearing hearing protection (odds ratio = 0.42, 95% confidence interval = 0.29-0.62). CONCLUSIONS: To our knowledge, this preliminary study is the first to demonstrate that hearing protection is associated with lower odds of non-impact, blast-induced concussion. The benefits of using hearing protection in terms of force readiness could be significant since many service members wounded in recent conflicts were diagnosed with concussion.

In Their Own Words: Caregiver and Patient Perspectives on Stressors, Resources, and Recommendations in Craniofacial Microsomia Care.

This study describes stressors, resources, and recommendations related to craniofacial microsomia (CFM) care from the perspective of caregivers of children with CFM and adults with CFM to inform improved quality of healthcare delivery. A mixed method design was used with fixed-response and open-ended questions from an online survey in English. The survey included demographics, CFM phenotypic information, and items about CFM-related experiences across settings. Themes were identified by qualitative analysis of responses to open-ended questions. Respondents (n = 51) included caregivers (n = 42; 90% mothers) and adults with CFM (n = 9; 78% female), who had a mean age of 45 ±â€Š6 years. Most children were male (71%) with an average age of 7 ±â€Š4 years. Respondents were primarily white (80%), non-Hispanic (89%), from the United States (82%), had a college degree (80%), and had private health insurance (80%). Reflecting the high rate of microtia (84%) in the sample, themes centered on the impact of hearing difficulties across settings with related language concerns. Negative social experiences were frequently described and school needs outlined. Multiple medical stressors were identified and corresponding suggestions included: providers need to be better informed about CFM, treatment coordination among specialists, and preference for a family-centered approach with reassurance, empathy, and clear communication. Advice offered to others with CFM included positive coping strategies. Overall, caregivers' and patients' responses reflected the complexity of CFM treatment. Incorporating these perspectives into routine CFM care has the potential to reduce family distress while improving their healthcare.

[Impaired recognition of environmental sounds in patients with dementia : I can hear but I do not understand]. / Störung des Erkennens von Umweltgeräuschen bei Demenz : Ich höre aber ich verstehe nicht.

BACKGROUND: Impairment of central auditory processing is a well-known symptom of neurodegenerative dementia; however, whilst numerous studies have examined verbal processing impairment, to date few have attempted to describe impairments of non-verbal, environmental sound recognition in patients with dementia. As these impairments may have direct implications on patient support and care, such studies are urgently necessary. AIM OF THE STUDY: The aim of the study was to determine whether the recognition of meaningful environmental sounds is impaired in patients with mild or early stage neurodegenerative dementia. PATIENTS AND METHODS: We developed a test of non-verbal sound recognition consisting of 16 sound sequences from the familiar and unfamiliar environments. We included 18 patients with mild cognitive impairment and mild dementia caused by Alzheimer's disease and frontotemporal dementia, as well as 20 cognitively healthy controls. RESULTS: Patients and controls were given the test of recognizing 16 meaningful sounds from the familiar and unfamiliar environments. Patients with dementia performed significantly worse in comparison to cognitively healthy controls. Whilst healthy controls correctly recognized on average 12.1 ± 2.2 out of 16 sounds, cognitively impaired patients recognized 9.2 ± 2.5. Correlation analysis showed that the mini mental state examination (MMSE) scores were positively correlated with the number of correctly recognized sounds (MMSE: r = 0.556, p = 0.017). DISCUSSION: The fact that even in mild stages of Alzheimer's disease or frontotemporal dementia patients either do not recognize or misinterpret environmental sounds must be taken into consideration not only in everyday life but in particular when patients need to leave their familiar living environment, whether temporarily (e. g. hospitalization) or permanently (e. g. nursing home admission).
