Value of ultrasonography in diagnosis of pediatric vocal fold paralysis

Conclusion
MGA and VAA are quantitative indicators of vocal fold immobility. Ultrasound is a reliable method of diagnosis of pediatric VFP. To diagnose VFP from an ultrasound image, the criteria are: (1) abnormal mobility (this was the most important and direct evidence), (2) hyperechoic air-column band of the glottic rima during phonation, (3) flaccid vocal fold and (4) asymmetry of the glottal structures.

Fiberoptic Endoscopic Evaluation of Swallowing in children: Feeding outcomes related to diagnostic groups and endoscopic findings

Conclusion
Many children overcome their dysphagia but those with neurologic disorders are less likely to achieve total oral feeding status. In children with dysphagia evaluated by FEES, the long-term feeding status is not significantly associated with the initial FEES findings.

Morphometric Differences in the Heschl’s Gyrus of Hearing Impaired and Normal Hearing Infants

This study investigates the morphometry of Heschl’s gyrus and its included primary auditory cortex (PAC) in hearing impaired (HI) and normal hearing (NH) infants. Fourty-two infants, age 8–19 months, with NH (n = 26) or hearing impairment (n = 16) were studied using high-resolution 3D magnetic resonance imaging. Gray matter (GM) and white matter (WM) volumes were obtained using software for automatic brain imaging segmentation to estimate the volume of each tissue within manually defined regions for the anterior portion of Heschl’s gyrus (aHG) in each individual subject, transformed to an infant brain template space. Interactions among group (HI, NH), tissue type (GM, WM), and hemisphere (left, right) were examined using analysis of variance. Whole-brain voxel-based morphometry was utilized to explore volume differences between groups across the entire brain. The HI group showed increased GM and decreased WM in aHG compared with the NH group; likely effects of auditory deprivation. The HI group did not exhibit their typical L > R asymmetry pattern that the NH group showed. Increased GM in aHG in HI infants may represent abnormal cortical development in PAC as seen in animal models of sensory deprivation. Lower WM volume is consistent with studies with deaf adults.

Mandarin Chinese speech recognition by pediatric cochlear implant users

Consistent with previous studies’ findings, early implantation provided a significant advantage for profoundly deaf children. Performance for both groups was generally quite good for the relatively difficult materials and tasks, suggesting that open-set word and sentence recognition may be useful in evaluating speech performance with older pediatric CI users. Differences in disyllable recognition between Groups 1 and 2 may reflect differences in adaptation to electric stimulation. The Group 1 subjects developed speech patterns exclusively via electric stimulation, while the Group 2 subjects adapted to electric stimulation relative to previous acoustic patterns.

Communication vulnerable patients in the pediatric ICU: Enhancing care through augmentative and alternative communication

Children in pediatric intensive care units (PICUs) may experience a broad range of motor, sensory, cognitive, and linguistic difficulties that make it difficult for them to communicate effectively. Being unable to communicate is emotionally frightening for children and can lead to an increase in sentinel events, medical errors and extended lengths of stay. Implementation of augmentative and alternative communication (AAC) tools and strategies can address the communication needs of children in the PICU by enabling them to communicate their wants, needs and feelings to healthcare providers and family members and participate in their own care more productively.<p><p>from the <a href=”Journal” _mce_href=”http://iospress.metapress.com/content/17214k076508n4k7/”><em>Journal”>http://iospress.metapress.com/content/17214k076508n4k7/”><em>Journal of Pediatric Rehabilitation Medicine</em></a></p>

Measuring communicative performance with the FAPCI instrument: Preliminary results from normal hearing and cochlear implanted children

Conclusion
: Normal hearing children demonstrated increasing FAPCI scores with age, and these preliminary growth curves allow for the interpretation of a cochlear-implanted child’s FAPCI scores in comparison to normal hearing children. Additional research using a larger, longitudinal cohort of normal hearing children will be needed to develop definitive normative FAPCI trajectories.

Postcricoid vascular lesions Histopathological and Immunohistochemical Diagnosis

Conclusions:
Patients with postcricoid vascular lesions usually present with mild to moderate feeding difficulties, and stridor or dyspnea with agitation. Histopathology and immunohistochemistry results suggest that postcricoid vascular lesions may often represent congenital vascular malformations instead of infantile hemangiomas.

Racial/Ethnic and socioeconomic disparities in the prevalence and treatment of otitis media in children in the United States†‡

Racial/ethnic and socioeconomic disparities exist for the prevalence and treatment of children with OM. Socioeconomic deprivation increases the risk of OM in children. Despite the frequency of tympanostomy tube insertion in children in the United States, few studies have addressed inequalities in access or utilization of surgical therapy. Given the changing healthcare climate and the social and economic impact of OM in children, further investigation of racial/ethnic and socioeconomic disparities targeting access to surgical treatment of OM should take precedence in health services research.

Long term hearing degeneration after platinum-based chemotherapy in childhood

The aim of this study was to investigate long-term development of hearing in subjects who had received platinum-based chemotherapy in childhood or adolescence. Another aim was to assess the self-reported hearing loss handicap and compare it to audiometric measurements. Medical records from individuals diagnosed with childhood cancer and treated with platinum-based chemotherapy between 1985 and 2000 at the University Hospital in Lund Sweden were reviewed retrospectively. Fifteen subjects, who fulfilled the eligibility criteria set for the study, underwent a thorough audiometric evaluation. The results show that the hearing loss, in subjects with ototoxicity had increased after the end of treatment, to include also the lower frequencies. The largest deterioration in hearing thresholds, up to 55 dB HL, was found at frequencies above 2 kHz. The findings also reveal that the subjects have a considerably greater hearing loss handicap and disability than would be expected from the results of the audiometric evaluations. The conclusion of this study is that children and adolescence treated with platinum-based chemotherapy should have regular audiometric follow-up examinations, also many years after the end of treatment. Furthermore, assessments of self-reported hearing disability should be made during and after chemotherapy.

Comparison of Traditional Bone-Conduction Hearing Aids with the Baha® System

The Baha system is a valid treatment in conductive hearing loss via a Softband or implanted. It statistically outperforms the traditional bone-conduction hearing aids and should be used as a first choice in intervention rather than a last option for inoperable conductive hearing loss.

Exploration of the relationships among medical health history variables and aspiration

Significant relationships exist between aspiration or penetration and the family’s answers about their child’s medical history. Practitioners should consider a swallow assessment whenever a child has a history which includes variables with a strong association with aspiration or penetration.

Pediatric cholesteatoma and variants in the gene encoding connexin 26

Abstract

Objectives/Hypothesis:
Connexin 26 is a gap junction protein encoded by the GJB2 gene. It is expressed in cholesteatoma, and mutations cause proliferative skin disorders and sensorineural hearing loss (SNHL). Deletions of GJB6, which encodes connexin 30, cause SNHL in a digenic manner with a heterozygous GJB2 mutation. We hypothesize that GJB2 and GJB6 mutations might influence the development of cholesteatoma.

Study Design:
Prospective observational study to identify GJB mutations in pediatric cholesteatoma.

Methods:
Peripheral blood samples from 98 children with cholesteatoma were screened for mutations in the GJB2 gene by direct sequencing of the coding region (exon 2 and the intron/exon boundary). Deletions of the GJB6 gene were tested using multiple ligation probe amplification methods. GJB status was compared with other populations and patient age and extent of cholesteatoma at presentation.

Results:
Fourteen children had at least one GJB2 variant (14%). Of these, three had two variants. Two of the variants were neutral polymorphisms. One child with the GJB2 genotype 35delG/35delG also had SNHL. No correlation was found between GJB2 status and patient age or cholesteatoma severity at presentation. No GJB6 deletions were found.

Conclusions:
GJB2 gene variants are present in a minority of children with cholesteatoma, but may be more common than in normal populations. It is conceivable that alterations of connexin 26 expression could contribute to the multifactorial disease process in cholesteatoma by modifying the cell-to-cell communication that is important in proliferation and migration of keratinocytes.

Multiple benefits of personal FM system use by children with auditory processing disorder (APD)

Children with auditory processing disorders (APD) were fitted with Phonak EduLink FM devices for home and classroom use. Baseline measures of the children with APD, prior to FM use, documented significantly lower speech-perception scores, evidence of decreased academic performance, and psychosocial problems in comparison to an age- and gender-matched control group. Repeated measures during the school year demonstrated speech-perception improvement in noisy classroom environments as well as significant academic and psychosocial benefits. Compared with the control group, the children with APD showed greater speech-perception advantage with FM technology. Notably, after prolonged FM use, even unaided (no FM device) speech-perception performance was improved in the children with APD, suggesting the possibility of fundamentally enhanced auditory system function.

Two Ears and Two (or More?) Devices: A Pediatric Case Study of Bilateral Profound Hearing Loss

Advances in technology and expanding candidacy guidelines have motivated many clinics to consider children with precipitously sloping high-frequency hearing loss as candidates for cochlear implants (CIs). A case study is presented of a pediatric CI patient whose hearing thresholds were preserved within 10 dB of preimplant levels (125-750 Hz) after receiving a fully inserted 31.5-mm electrode array at one ear. The primary goal of this study was to explore the possible benefit of using both a hearing aid (HA) and a CI at one ear while using a HA at the opposite ear. The authors find that although the use of bilateral hearing aids with a CI may only provide a slight benefit, careful attention must be paid to the coordinated fitting of devices, especially at the ear with two devices.
