A Study of Effect of Consanguinity on Cochlear Morphology in Patients with Congenital Bilateral Profound Sensorineural Hearing Loss

This study was conducted to know the effect of consanguinity on cochlear morphology, if any. A prospective, observational study, including prelingually deaf children with bilateral profound sensorineural hearing loss who are registered as candidates for cochlear implantation at a tertiary care centre, was conducted. Seven children born out of consanguineous marriages and having bilateral congenital sensorineural hearing loss were imaged for their inner ears by MRI and various cochlear measurements were compared with that of seven control children born out of non-consanguineous marriages and who had congenital bilateral sensorineural hearing deafness. No statistically significant differences were noticed in the measurements of mean cochlear length, cross sectional diameter of cochlea at apex, middle turn and at basal turns; between children born of consanguineous and non-consanguineous marriages. Study revealed normal cochlear morphology in all the children born out of consanguineous marriages. Consanguinity, as a risk factor for development of sensorineural hearing loss, may not result in gross structural anomaly of cochlea. The genetic testing of these patients need not be extensive and can be limited to selective screening of genes responsible for functioning of cochlea rather than its anatomical development.

Authors: Deng JH, Du JH, Ma XR, Zhang PF Abstract The present study explored the application of auditory cortical evoked potentials (ACEP) in the auditory assessment of people using an auditory prosthesis. There were 126 patients with prelingual deafness who were selected from January 2012-June 2017 from the First People's Hospital of Kunshan (Kunshan, China). HEARLab™ system was used to induce a P1-N1-P2 waveform under the condition of 60 dB sound pressure level at /m/, /g/ and /t/ acoustic stimulations. Speech production ability and auditory perception ability of patients were evaluated by speech intelligib...

ConclusionThis research describes for the first time the frequency of the 35delG and D13S1830 mutation in hearing-impaired individuals from Minas Gerais, Brazil, and the collected data reinforce the need for further studies in this population due to heterogeneity of hearing loss.ResumoIntroduçãoA surdez é o déficit sensorial mais frequente em humanos. Estima-se que a incidência seja de 4: 1000 nascimentos no Brasil. Programas específicos para atendimento clínico de pacientes com perda auditiva são escassos no Brasil e a questão é um importante problema de...

Publication date: August 2019Source: Journal of Neurolinguistics, Volume 51Author(s): Qiang Li, Huang Guo, Lihua Liu, Shuang XiaAbstractEarly hearing deprivation can affect the development of hearing, language, and vision. Thirty-four infants with congenital severe sensorineural hearing loss (CSSHL) and 20 age- and sex-matched subjects with normal hearing were recruited. The amplitude of low-frequency fluctuation (ALFF) of auditory and language-related brain areas was compared between infants with deafness and control subjects. Relative to subjects with normal hearing, infants with CSSHL had decreased ALFF values in the ri...

The objectives of the current study were (1) to assess the prevalence of microcephaly and other brain findings in infected and affected fetuses and infants, (2) to compare these findings with other congenital ZIKV series reported to date, and (3) to provide quantitative measures of magnetic resonance imaging (MRI) of fetal and infant brain imaging.

(Natural News) Whether it’s just plain arrogance or a lack of proper education — or both — New York Democratic Socialist Rep.
