Introduction: Serum Anti endothelial Cell Antibodies (AECAs) play a prominent role in idiopathic Sensorineural Hearing Loss (SNHL) in that they induce vascular damage (immune mediated).The of the current study is  To compare AECAs in serum and perilymphatic .uid of idiopathic SNHL children (<15y) undergoing cochlear implant surgery.Methods: This was a cross sectional study performed in the coch...

Inhibitory neurotransmission is a critical determinant of neuronal network gain and dynamic range, suggesting that network properties are shaped by activity during development. A previous study demonstrated that sensorineural hearing loss (SNHL) in gerbils leads to smaller inhibitory potentials in L2/3 pyramidal neurons in the thalamorecipient auditory cortex, ACx. Here, we explored the mechani...

The objective was to determine frequency of sensorineural hearing loss (SNHL), identified by abnormal threshold in evoked potentials, absence of otoacoustic emissions and behavioral responses, auditory neuropathy (AN) (absence of evoked potentials, with preservation of otoacoustic emissions), and neurological comorbidity in infants with hyperbilirubinemia (HB) treated with exchange-transfusion ...

INTRODUCTION This study was designed to compare the sensitivity and specificity of detecting sensorineural hearing loss (SNHL) using the transient-evoked otoacoustic emissions (OAE) machine (the Madsen TE Echoscreen) and automated auditory brainstem response (AABR) machine (the Sabre Compac portable AABR) in term neonates exposed to severe hyperbilirubinaemia. METHODS This was a prospective s...

The discrimination of interaural phase differences (IPDs) requires accurate binaural temporal processing and has been used as a measure of sensitivity to temporal envelope and temporal fine structure (TFS). Previous studies found that TFS-IPD discrimination declined with age and with sensorineural hearing loss (SNHL), but age and SNHL have often been confounded. The aim of this study was to det...

Mutations of MYO15A are generally known to cause severe to profound hearing loss throughout all frequencies. Here, we found two novel MYO15A mutations, c.3871C>T (p.L1291F) and c.5835T>G (p.Y1945X) in an affected individual carrying congenital profound sensorineural hearing loss (SNHL) through targeted resequencing of 134 known deafness genes. The variant, p.L1291F and p.Y1945X, resided in the ...

Hearing loss is one of the most common disabilities and has lifelong consequences for affected children and their families. Both conductive and sensorineural hearing loss (SNHL) may be caused by a wide variety of congenital and acquired factors. Its early detection, together with appropriate intervention, is critical to speech, language and cognitive development in hearing-impaired children. In...

INTRODUCTION A considerable high number of SNHL patients also suffer from dizziness and related vestibular symptoms. OBJECTIVE To evaluate the association of vestibular dysfunction and sensorineural hearing loss (SNHL) in adult patients. METHODS Prospective, double-blinded, controlled studies composed by 63 adult patients without any vestibular symptoms or diagnosed vestibular diseases. Aud...

CONTEXT Endolymphatic sac tumors (ELSTs) are associated with von Hippel-Lindau disease and cause irreversible sensorineural hearing loss (SNHL) and vestibulopathy. The underlying mechanisms of audiovestibular morbidity remain unclear and optimal timing of treatment is not known. OBJECTIVE To define the mechanisms underlying audiovestibular pathophysiology associated with ELSTs. DESIGN, SETT...
