Emotional recognition of dynamic facial expressions before and after cochlear implantation in adults with progressive deafness.

Emotional recognition of dynamic facial expressions before and after cochlear implantation in adults with progressive deafness. Hear Res. 2017 Aug 31;354:64-72 Authors: Ambert-Dahan E, Giraud AL, Mecheri H, Sterkers O, Mosnier I, Samson S Abstract Visual processing has been extensively explored in deaf subjects in the context of verbal communication, through the assessment of speech reading and sign language abilities. However, little is known about visual emotional processing in adult progressive deafness, and after cochlear implantation. The goal of our study was thus to assess the influence of acquired post-lingual progressive deafness on the recognition of dynamic facial emotions that were selected to express canonical fear, happiness, sadness, and anger. A total of 23 adults with post-lingual deafness separated into two groups; those assessed either before (n = 10) and those assessed after (n = 13) cochlear implantation (CI); and 13 normal hearing (NH) individuals participated in the current study. Participants were asked to rate the expression of the four cardinal emotions, and to evaluate both their emotional valence (unpleasant-pleasant) and arousal potential (relaxing-stimulating). We found that patients with deafness were impaired in the recognition of sad faces, and that patients equipped with a CI were additionally impaired in the recognition of happiness and fear (but not anger). Relative to controls, all patients with de...

Authors: Jones ML, Morris JT, Mueller JL, Lippincott B, Sweatman WM Abstract Accessibility of telecommunication technologies by people who are deaf or hard of hearing has been a critical issue since the invention of the telephone. As both telephone and hearing-aid technologies have evolved, finding compatible solutions has been an ongoing challenge. This paper uses the findings of a longitudinal study to examine the impact of Federal hearing-aid compatibility (HAC) regulations in resolving this problem. The study ran concurrently with the phase-in of Federal Communications Commission regulations requiring that mobi...

Lee Sign language is intentionally designed to allow deaf and dumb communities to convey messages and to connect with society. Unfortunately, learning and practicing sign language is not common among society; hence, this study developed a sign language recognition prototype using the Leap Motion Controller (LMC). Many existing studies have proposed methods for incomplete sign language recognition, whereas this study aimed for full American Sign Language (ASL) recognition, which consists of 26 letters and 10 digits. Most of the ASL letters are static (no movement), but certain ASL letters are dynamic (they require certa...

Researchers from the University of Rochester found that viruses, genetics and even existing drugs could cause little hairs to regrow in the inner ear. These hairs pick up on noises entering the ear.

The objective of this report is to compare the characteristics of symptoms and differences in the therapeutic responses of them, who had the same mutation. In addition, we aimed to examine the usefulness of cytokine measurement for diagnosis or determination of treatment effect of CAPS. A 5-year-old Japanese boy (proband) came to our hospital because of short stature, reached the diagnosis of Muckle-Wells syndrome (MWS) due to a mutation inNLRP3 gene, which had not been reported so far (p.G328E, c.G983A). His mother and grandmother harbored the same mutation ofNLRP3. We measured serum concentrations of cytokines in the pro...

In this study, we investigated the pathogenic mechanism of deafness-associated 7505A > G variant in the mitochondrial tRNASer(UCN). The m.7505A > G variant affected the highly conserved adenine at position 11 (A11), disrupted the highly conserved A11-U24 base-pairing of DHU stem of tRNASer(UCN) and introduced a tertiary base pairing (G11-C56) with the C56 in the TΨC loop. We therefore hypothesized that the m.7505A > G variant altered both structure and function of tRNASer(UCN). We demonstrated that the m.7505A > G variant perturbed the conformation and stability of tRNASer(UCN), as indicated...

This study investigated visual statistical learning (VSL) in 24 deaf signers and 24 hearing non-signers. Previous research with hearing individuals suggests that SL mechanisms support literacy. Our first goal was to assess whether VSL was associated with reading ability in deaf individuals, and whether this relation was sustained by a link between VSL and sign language skill. Our second goal was to test the Auditory Scaffolding Hypothesis, which makes the prediction that deaf people should be impaired in sequential processing tasks. For the VSL task, we adopted a modified version of the triplet learning paradigm, with stim...

Abstract Diffuse esophageal leiomyomatosis is a rare esophageal tumor characterized by circumferential thickening of smooth muscle layers. Diffuse esophageal leiomyomatosis can be associated with Alport's syndrome and therefore diagnosed by skin biopsy. Alport syndrome is a hereditary disease usually defined by the association of glomerular nephropathy and perceptual deafness. Here we describe the management of a young women with a diffuse esophageal leiomyomatosis and a past history of uterine leiomyoma. The surgical treatment depends on the esophageal extent of the disease. Association between diffuse esophageal...

We present evidence that KID syndrome can be caused by a homozygous GJB2 mutation and demonstrate an autosomal recessive mode of inheritance for the first time at a molecular level.The spectrum of skin manifestations associated with gap junction gene mutations is still growing, particularly in the case of Cx26. Our findings add to the list of pathogenic variants associated with this condition, and contribute to an insight into the genotype-phenotype correlations of Cx26 mutations, thus elucidating the function of different regions of the protein and further add to the widely diverging associated phenotypes.
