ObjectiveTo assess the efficacy of valganciclovir in infants with hearing loss and clinically inapparent congenital cytomegalovirus infection (cCMV), as there is no consensus on treatment this group.Study designA nationwide, non-randomized controlled trial, comparing six weeks oral to cCMV, recruited after newborn screening resulted referral. The choice whether treat was left parents subjects. Eligible subjects were full term aged <13 sensorineural diagnosed cCMV through dried blood spot...
Objective The purpose of this study was to examine the level empathy in deaf and hard hearing (pre)adolescents compared normal controls define influence language various loss characteristics on development empathy. Methods group (mean age 11.9 years) consisted 122 children (52 with cochlear implants 70 conventional aids) 162 children. two groups were using self-reports, a parent-report observation tasks rate children’s empathy, their attendance others’ emotions, emotion recognition,...
The purpose of this study was to examine the levels depressive symptoms and unique contribution two aspects emotion regulation (coping mood states) development depression in hearing-impaired children a control group.In order compare groups, self-report questionnaires concerning depression, coping strategies, states were used. group consisted 27 with cochlear implants, 56 conventional hearing aids, 117 normally children.Hearing-impaired reliably reported more than their peers. Degree loss,...
Objective Sufficient self-esteem is extremely important for psychosocial functioning. It hypothesized that hearing-impaired (HI) children have lower levels of self-esteem, because, among other things, they frequently experience language and communication skills. Therefore, the aim this study was to compare HI children's across different domains with those normal hearing (NH) investigate influence communication, type education, audiological characteristics. Methods This large (N = 252)...
A directional hearing aid might be beneficial in reducing background noise relation to the desired speech signal. Conventional aids with a cardioid microphone are insufficient because of low directivity cardioids. Research was done develop microphone(s) strong characteristics using array techniques. Particular emphasis given optimization and stability. Free-field simulations several robust models show that index 9 dB can obtained at higher frequencies. Simulations were verified laboratory...
Hearing-impaired listeners often have great difficulty understanding speech in surroundings with background noise or reverberation. Based on array techniques, two microphone prototypes (broadside and endfire) been developed strongly directional characteristics [Soede et al., "Development of a new hearing instrument based technology," J. Acoust. Soc. Am. 94, 785-798 (1993)]. Physical measurements show that the arrays attenuate reverberant sound by 6 dB (free-field) can improve signal-to-noise...
The objectives of this study were to examine the levels anxiety in hearing-impaired children with hearing aids or cochlear implants compared normally children, and identify individual variables that associated differences level anxiety.Large retrospective cohort study.Self-reports parent-reports concerning general anxiety, social generalized disorder used. group (mean age, 11.8 years) consisted three age-matched subgroups: 32 implants, 51 conventional aids, 127 without loss.Levels similar....
Children with hearing loss are at risk of developing psychopathology, which has detrimental consequences for academic and psychosocial functioning later in life. Yet, the causes extensive variability outcomes not fully understood. Therefore, authors wanted to objectify symptoms psychopathology children cochlear implants or aids, normally peers, identify various protective factors.
Objective To evaluate clinical, audiological and neuroimaging findings in a cohort of infants diagnosed with congenital cytomegalovirus (cCMV) infection after failure at newborn hearing screening. Methods A prospective observational study the Netherlands, using existing screening infrastructure for well babies. Between July 2012 November 2016, (CMV) PCR testing neonatally obtained dried blood spots (DBS) was offered to all who failed Clinical, data were collected. Results DBS 1374...
Children with hearing loss (HL) are at risk for a lower educational achievement. This longitudinal study compared the school career of nationwide Dutch cohort and without HL based on descriptive data governmental authority Statistics Netherlands. From 2008 to 2018, 3,367,129 children, whom 1,193 used cochlear implants (CIs) 8,874 aids (HAs), were attending primary and/or secondary education. Sixty-one percent children attended mainstream 31% special Compared mainstreamed pupils HL, achieved...
In complex regional pain syndrome type 1 (CRPS-1), patients may have manifestations of central involvement, including allodynia, hyperalgesia or dystonia. We noted that more severely affected experience hyperacusis, which also reflect involvement. The aim this study was to evaluate the occurrence and characteristics hyperacusis in with CRPS related dystonia.The presence speech reception thresholds (SRT), pure-tone (PTT) uncomfortable loudness (UCL) evaluated 40 dystonia.PTT SRT were normal...
Objectives: The first aim of this study was to examine various aspects Theory Mind (ToM) development in young children with moderate hearing loss (MHL) compared peers. second the relation between language abilities and ToM both groups. third compare sequence MHL Design: Forty-four 3 5 years old (35 70 dB HL) who preferred use spoken were identified from a nationwide on children. These 101 Children observed during several tasks measure intention understanding, acknowledgement other’s desires,...
One way to improve speech understanding in noise for HI with a unilateral hearing loss is by contralateral routing of signals (CROS). Such CROS-system captures sounds an additional microphone at the worst ear and transmits these better one. The then provided mix originating from both ears. goal this study quantify effect on reception thresholds (SRTs) unilaterally implanted CI-users diffuse directional as function speaker location. Listening tests are performed accurate intelligibly model...
In Brief Objective: To evaluate the improvement in speech intelligibility noise obtained with an assistive real-time fixed endfire array of bidirectional microphones comparison omnidirectional hearing aid microphone a realistic environment. Design: The was evaluated physically anechoic and reverberant conditions. Perceptual tests were carried out room, two types six different scenarios single multiple sources. Ten normal-hearing subjects 10 users participated. reception threshold for...
People with cochlear implants have severe problems speech understanding in noisy surroundings. This study evaluates and quantifies the effect of two assistive directional microphone systems compared to standard headpiece on perception quiet surroundings background noise, a laboratory setting developed reflect situation whereby listener is disturbed by noise mainly diffuse character due many sources reverberant room.Thirteen postlingually deafened patients, implanted Leiden University Medical...
Cochlear implants (CIs) have dramatically improved the lives of children who are deaf or hard hearing; however, little is known about its implications for preventing development psychiatric symptoms in this at-risk population. This first longitudinal study to examine early manifestation emotional and behavioral disorders associated risk protective factors identified preschoolers with CIs compared hearing peers.Participants were 74 190 controls between ages 1 5 years (mean age, 3.8 years)....
There is lack of a systematic approach concerning how to select an adequate hearing aid and evaluate its efficacy with respect the personal needs rehabilitation. The goal this study was examine applicability added value two widely used self-reporting questionnaires in relation evaluation fitting. We analyzed responses, pre- postfitting, from 1,319 subjects who completed Client Oriented Scale Improvement (COSI) slightly adapted version Amsterdam Inventory for Auditory Disability Handicap (in...
