Congenital cytomegalovirus (CMV) infection is the most common non-hereditary cause of sensorineural hearing loss (SNHL) yet the mechanisms of hearing loss remain obscure. Natural Killer (NK) cells play a critical role in regulating murine CMV infection via NK cell recognition of the Ly49H cell surface receptor of the viral-encoded m157 ligand expressed at the infected cell surface. This Ly49H N...
OBJECTIVE To investigate risk factors for sensorineural hearing loss (SNHL) in children after liver transplantation. DESIGN Retrospective medical record review. SETTING Pediatric tertiary care hospital. PATIENTS One hundred twenty-five consecutive children who received liver transplants between March 1, 1987, and June 30, 1996. MAIN OUTCOME MEASURES The presence of SNHL (bone conduction...
Mutations in the ATP6V1B1 and ATP6V0A4 genes, encoding subunits B1 and 4 of apical H(+) ATPase, cause recessive forms of distal renal tubular acidosis (dRTA). ATP6V1B mutations have been associated with early sensorineural hearing loss (SNHL), whereas ATP6V0A4 mutations are classically associated with either late-onset SNHL or normal hearing. The phenotype and genotype of 39 new kindreds with r...
Introduction: Hearing impairment is the most frequent sensorial congenital defect in newborns and has increased to 2–4 cases per 1,000 live births. Sensory-neural hearing loss (SNHL) accounts for more than 90% of all hearing loss. This disorder is associated with other congenital disorders such as renal, skeletal, ocular, and cardiac disorders. Given that congenital heart diseases are life-thre...
A detailed analysis of risk factors for the development of sensorineural hearing loss (SNHL) was carried out in 199 forest workers. The hearing threshold of both ears at 4000 Hz was measured, and the effect of age, exposure to noise, blood pressure, presence of vibration induced white finger (VWF), tobacco smoking, plasma LDL-cholesterol concentration, and consumption of drugs were evaluated by...
Introduction: In this study, we examined the role of immunological factors on sudden sensory neural hearing loss (SSNHL). Materials and Methods: This prospective case-controlled study was performed in patients with SSNHL who referred to the ear, nose, and throat (ENT) ward. Fifty-six patients with SSNHLoccurring within a 72-hr period were selected as the case group and 56 participants who ha...
Verbal communication in noisy backgrounds is challenging. Understanding speech in background noise that fluctuates in intensity over time is particularly difficult for hearing-impaired listeners with a sensorineural hearing loss (SNHL). The reduction in fast-acting cochlear compression associated with SNHL exaggerates the perceived fluctuations in intensity in amplitude-modulated sounds. SNHL-i...
Abstract Background Hearing loss can greatly affect the overall quality of life. Several studies have reported that patients with SLE may suffer from audio-vestibular manifestations. The aim this study is to evaluate influence systemic lupus erythematosus (SLE) on hearing and association impairment severity duration SLE. Results Pure-tone audiometry (PTA) (air conduction bone conduction) thresh...
inner ear cells are sensitive to some metabolic and hormonal disorders, but the relation between chronic renal failure (crf), regular dialysis treatment (rdt) and sensorineural hearing loss (snhl) is still a debatable field. the object of this paper was to verify the presence of snhl in patients submitted to hemodialysis with different duration due to crf and in those submitted to conservative ...
Sensorineural hearing loss (SNHL) is a heterogeneous family of hearing disabilities with congenital (including genetic) as well as acquired etiology. Congenital SNHL of genetic etiology is further sub-divided into autosomal dominant, autosomal recessive and X-linked SNHL. More than 60 genes are involved in the etiology of autosomal recessive non-syndromic hearing loss (ARNSHL) commonly manifest...
