CONCLUSIONS Congenital cytomegalovirus (CMV) infection is a major cause of bilateral and unilateral sensorineural hearing loss (SNHL) in children, accounting for 9.0% of SNHL cases. The diagnostic rate using combined genetic deafness test and CMV DNA detection test was determined to be 46.4% in bilateral profound SNHL. OBJECTIVES The present study investigated the prevalence of congenital CMV...

Keratitis-Ichthyosis-Deafness syndrome is a rare congenital disorder of the ectoderm caused by mutations in the connexin-26 gene (GJB2) on chromosome 13q11-q12, giving rise to keratitis, erythrokeratoderma and neurosensory deafness. We report the case of a 31-year-old black male diagnosed as having KID syndrome. Sequencing analysis showed a heterozygous missense mutation D50N (148G > A) in the ...

Mutations in the DFNB1 locus, where two connexin genes are located (GJB2 and GJB6), account for half of congenital cases of nonsyndromic autosomal recessive deafness. Because of the high frequency of DFNB1 gene mutations and the availability of genetic diagnostic tests involving these genes, they are the best candidates to develop a risk prediction model of being hearing impaired. People underg...

INTRODUCTION Children with severe to profound sensorineural deafness can acquire vocabulary and syntactic structures to communicate by oral language, after cochlear implant. AIM Identify the linguistic skills of children with cochlear implant. MATERIAL AND METHODS Eighteen children of both gender, between 9 and 10 years, with congenital bilateral deafness, using cochlear implant, were studi...

Keratitis-Icthyosis-Deafness (KID) syndrome is a rare dysplasia characterized by vascularizing keratitis, congenital sensorineural hearing-loss, and progressive erythrokeratoderma. To our knowledge, this is the first KID syndrome imaged with FDG-PET in the literature. This paper is intended to help familiarize with the FDG abnormalities related to this rare entity.

Introduction: Congenital anomalies of the cochlea and labyrinth can be associated with meningitis and varying degrees of hearing loss or deafness. Despite antibiotics, meningitis remains a life threatening complication.   Case Report: We report a case of recurrent meningitis following episodes of otitis media in a cochlear implantee child with bilateral vestibulocochlear malformation, due to f...

Congenital hearing loss has been documented to occur in 1 of 1000 live births, with over half of these cases predicted to be hereditary in nature. 2 Most hereditary hearing loss is inherited in a recessive manner, accounting for approximately 85% of non-syndromic hearing loss (NSHL). Deafness is an extremely genetically heterogeneous disorder, shown by the fact that 33 loci for recessive NSHL a...

BACKGROUND Congenital hereditary sensorineural deafness (CHSD) occurs in many dog breeds, including Australian Cattle Dogs. In some breeds, CHSD is associated with a lack of cochlear melanocytes in the stria vascularis, certain coat characteristics, and potentially, abnormalities in neuroepithelial pigment production. This study investigates phenotypic markers for CHSD in 899 Australian Cattle ...

Barakat syndrome, also known as hypoparathyroidism, sensorineural deafness, and renal dysplasia syndrome is an extremely rare congenital disorder. Different etiologies are described for the syndrome but the definite pathophysiology remains unclear. Hereby, we present a case of Barakat syndrome who was diagnosed on the basis of clinical and molecular data.

A diagnosis of Epstein's syndrome was made in a young female with congenital macrothrombopathic thrombocytopenia, a nephropathy and mild sensorineural deafness. Previous case reports of this rare disorder are briefly reviewed and attention is drawn to the frequent association between inherited thrombocytopenia and renal disease.
