Vestibular Impairment and Postural Development in Children With Bilateral Profound Hearing Loss.

Importance: Children with profound hearing loss (HL) and vestibular impairment have worse cochlear implant outcomes compared with those without vestibular impairment. However, the decision for cochlear implantation is rarely based on vestibular function assessment as a complement to audiologic testing.

Objectives: To identify the prevalence of vestibular impairment according to HL origin and to assess the association between vestibular impairment and delayed posturomotor development in children with profound HL.

Olfactory function in congenital cytomegalovirus infection: a prospective study.

Congenital cytomegalovirus (CMV) infection leads to olfactory bulb lesions in the fetus, yet little is known about its impact on olfaction after birth. Here, we have assessed in a prospective study conducted on children in two French hospitals from 2016 to 2019, infection severity and olfactory performance after congenital CMV infection. Children with congenital CMV infection aged 3 to 10 years and healthy controls (CTL) matched for age and sex to CMV children symptomatic at birth (sCMV) were enrolled.

Vestibular Migraine of Childhood and Recurrent Vertigo of Childhood: Diagnostic criteria Consensus document of the Committee for the Classification of Vestibular Disorders of the Bárány Society and the International Headache Society.

This paper describes the diagnostic criteria for "Vestibular Migraine of Childhood", "probable Vestibular Migraine of Childhood" and "Recurrent Vertigo of Childhood" as put forth by the Committee for the Classification of Vestibular Disorders of the Bárány Society (ICVD) and the Migraine Classification subgroup of the International Headache Society. Migraine plays an important role in some subgroups of children with recurrent vertigo. In this classification paper a spectrum of three disorders is described in which the migraine component varies from definite to possibly absent.

Subjective visual vertical in patients with Usher syndrome.

Background: Verticality, or more precisely the ability to perceive spatial orientation with regard to gravity, is based on the integration of visual, vestibular and somesthetic information.

Objective: The purpose of the present study was to compare the subjective visual vertical (SVV) in patients with Usher (type I and type II) with visual or vestibular impairment, and in healthy participants, in order to explore the importance of the visual and vestibular functions on the vertical’s perception.

Methods: We evaluated the SVV using a wall housing which projects on the opposite wall a red-light line of about 2 meters, obtained by laser cannon.

Visual searching capabilities in Age-Related Macular Degeneration (AMD) subjects.

A decrease in visual perception with age was observed due to a decline in neurocognitive and visual functions. Previous studies showed that aging affects visual processes and contextual perceptual phenomena. The aim of our study was to explore the effect of age as well as the effect of Age-Related Macular Degeneration (AMD) on the visual searching task.

Postural Instability in Subjects With Usher Syndrome.

This study investigated postural performances and vestibular impairment in Usher patients. The three groups studied were: 11 patients with Usher type I (with visual and vestibular impairment), 14 patients with Usher type II (with only visual impairment), and 14 healthy control subjects. Postural stability was measured with a Framiral Multitest Equilibre platform with three visual conditions: eyes open (EO), eyes closed (EC), and vision disturbed by optokinetic stimulation (OPT), and two different postural conditions: stable or unstable platform.

Dizziness and Convergence Insufficiency in Children: Screening and Management.

Objective: In children screened for dizziness with vergence disorders, we tested short and long term efficacy of orthoptic vergence training (OVT) and instructions to reduce screen usage.

Methods: Prospective study: Of the 179 children referred for vertigo or dizziness (over 3 years) with ophthalmological disorder as the only problem after complete oto-neuro-vestibular testing, 69 presented vergence insufficiency, and 49 accepted to participate in this study. 109 healthy children served as controls.

Changes of spatial and temporal characteristics of dynamic postural control in children with typical neurodevelopment with age: Results of a multicenter pediatric study.

Background: The aim of this multicenter study is to investigate the effect of chronological age and gender in postural control.

Methods: To approach an ecological model, we used a multicenter posturography assessment. We analyzed postural control with surface, mean velocity of center of pressure [CoP] and temporal analysis, with Postural Instability Index [PII] being a more sensitive parameter in postural evaluation.

Epidemiology of Vestibular Impairments in a Pediatric Population.

The purpose of this study was to report the prevalence of vestibular impairment (VI) in children (  = 2,528) referred for complete vestibular testing because of balance disorders (BD) or hearing loss (H). A VI was shown in 51.5% of the children tested (1,304/2,528).

Reduced Balance Restoration Capacities Following Unilateral Vestibular Insult in Elderly Mice.

Acute vestibular syndrome (AVS) is characterized by severe posturo-locomotor and vestibulo-oculomotor impairment and accompanies several types of peripheral vestibulopathies (PVP). We know very little about its etiology, how its various symptoms are expressed and how it evolves with age. Robust repair capabilities of primary vestibular synapses have recently been shown to restore behavioral functionality.

Video Head Impulse Tests with a Remote Camera System: Normative Values of Semicircular Canal Vestibulo-Ocular Reflex Gain in Infants and Children.

The video head impulse test (VHIT) is widely used to identify semicircular canal function impairments in adults. But classical VHIT testing systems attach goggles tightly to the head, which is not tolerated by infants. Remote video detection of head and eye movements resolves this issue and, here, we report VHIT protocols and normative values for children.

Developmental study identifies the ages at which the processes involved in the perception of verticality and in postural stability occur.

Aim: The aim of this study was to understand the role played by visual information on the development of verticality and postural stability in healthy children.

Methods: The study comprised 66 healthy children from 4.0 to 15.

Up/down anisotropies of vertical saccades in healthy children depending on the mode and the depth of execution.

While the overall development of saccades in children has recently gained increasing interest, the precise characteristics of vertical saccades remain understudied. The few adult studies existing showed up/down anisotropies on various parameters. This study focuses on the development of vertical saccades and their interaction with vergence movements, according to the mode of initiation of the saccades (automatic and controlled).

A case of mild CHARGE syndrome associated with a splice site mutation in CHD7.

CHARGE syndrome (MIM#214800) (Coloboma, Heart defect, Atresia of choanae, Retarded growth and development, Genital hypoplasia, Ear abnormalities/deafness) is caused by heterozygous mutation of CHD7 transmitted in an autosomal dominant manner. In this report, we describe a patient with bilateral hearing impairment, unusually-shaped ears, no intellectual disability and a patent ductus arteriosus. Further investigation showed abnormal semicircular canals and the presence of olfactory bulbs.

Vestibular Disorders in Children With Congenital Cytomegalovirus Infection.

Background: Congenital cytomegalovirus (CMV) infection is the leading infectious cause of neurologic disabilities and sensorineural hearing loss in children. Sensorineural hearing loss prevalence in CMV suggests a viral tropism for the inner ear. Vestibular disorders induced by CMV infection are underestimated.
