VALGANCICLOVIR IN INFANTS WITH HEARING LOSS AND CLINICALLY INAPPARENT CONGENITAL CYTOMEGALOVIRUS INFECTION: A NONRANDOMIZED CONTROLLED TRIAL
Pui Khi Chung, MD, Fleurtje A. J. Schornagel, MD, Wim Soede, PhD, Erik W. van Zwet, PhD, Aloys C. M. Kroes, Professor, MD, PhD, Anne Marie Oudesluys-Murphy, Professor, MD, PhD, and Ann C. T. M. Vossen, PhD

To assess the efficacy of valganciclovir in infants with hearing loss and clinically inapparent congenital cytomegalovirus infection (cCMV), as there is no consensus on treatment of this group.

At the follow-up age of 18–22 months, an auditory brainstem response was performed by a trained investigator during a home visit or at the study site, using a Vivosonic Integrity™ device (Vivosonic Inc., Canada).

EVALUATION OF HEARING IMPAIRMENT IN PATIENTS WITH DOWN SYNDROME

It is estimated that the prevalence of hearing loss in children with Down syndrome (DS) ranges from 38% to 82%. However, the diagnosis of hearing loss in DS is difficult, due to an impaired ability to cooperate for subjective tests. Thus, objective tests such as impedance audiometry, otoacoustic emissions, and auditory brainstem responses (ABRs) may be more appropriate. In this study objective methods without anesthesia were used to determine the amount, type, and prevalence of hearing loss in people with DS.

bilirubin hearing

A study of Hyperbilirubinic and normal newborns showed that Hyperbilirubinemic newborns had decreased Medial Olivocochlear (MOC) reflex activity. This may be indicative of future problems in speech discrimination and effective hearing in noisy background. Additional long cohort studies are needed to evaluate the clinical importance of MOC reflex measurements in this group.


apnea

Objective

Obstructive sleep apnea syndrome (OSAS) is a respiratory syndrome that manifests during sleep. For the auditory system to be able to function normally, the inner ear and cochlear nerve require healthy oxygen support. The purpose of this study was to assess the hearing function of patients with OSAS and to reveal the relationship between polysomnographic parameters and hearing test results.

Vivosonic’s policy is to provide support for a period of 5 years from the date of withdrawal of a product from the market. It is now over 5 years since the sale of our last new G1 system and we currently have a limited inventory of parts available to service or repair these G1 systems. We are no longer providing software updates for these G1 systems and we no longer support Windows 7. As also previously communicated, support and parts are no longer available for the XP version.

VEMP

Using the Vivosonic Integrity™ V500 System, the aim of this study was to investigate the VEMP* responses in conductive hearing loss using bone conduction stimulation. The response percentage of present VEMP waves by AC stimulation was 20% (4 ears). For BC stimulation, the rate increased to 75% (15 ears).

RESEARCH ARTICLE

Early Hearing Detection and Intervention: Timely Diagnosis, Timely Management

Findlen, Ursula M.; Hounam, Gina M.; Alexy, Emily; Adunka, Oliver F.

Ear and Hearing, August 2018

This study examined how three clinical practice changes affected age at diagnosis: 1) Using Kalman-weighted signal averaging for ABR assessment, 2) Using a tone burst-prioritized protocol for assessment, and 3) Expediting the initial visit for infants.

Regarding the technology used for assessments, Kalman-weighted signal averaging ABRs may decrease the age at hearing determination for infants. Two factors decreased across the study time period: 1) The need for multiple tests to confirm diagnosis due to limited data obtained at initial evaluation and 2) difficulty testing due to limited infant sleep duration. Both of these factors can be improved by using Kalman-weighted signal averaging, which enhanced data collection efficiency when compared with conventional methods.
