We investigated the choice of the surgery side for CI (i.e., the better- or poorer-hearing ear) in patients with asymmetric hearing. Audiological records of 74 adults with a unilateral hearing aid who had undergone surgery at Okayama University Hospital were reviewed. The definition of ‘better-hearing ear’ was the aided ear, and the unaided ear was considered the poorer-hearing ear. We performed a multiple regression analysis to identify potential predictors of speech recognition performance after unilateral CI in the patients. Fifty-two patients underwent CI in the poorer-hearing ear. The post-Ci bimodal hearing rate was far higher in the poorer-ear group (77.8% vs. 22.2%). A multivariate analysis revealed that prelingual hearing loss and the patient’s age at CI significantly affected the speech recognition outcome (beta coefficients: 24.6 and ?0.33, 95% confidence intervals [11.75-37.45] and [?0.58 to ?0.09], respectively), but the CI surgery side did not (?6.76, [?14.92-1.39]). Unilateral CI in the poorer-hearing ear may therefore be a reasonable choice for adult patients with postlingual severe hearing loss, providing a greater opportunity for postoperative bimodal hearing.

The patient was a 79-year-old woman. Her left ear was being treated with otitis externa at her nearby clinic by eardrop. Her otorrhea did not improve after one week. The otorrhea still kept outflowing during food intake. That is the reason of her visiting our hospital. Her past medical histories were sigmoid colon perforation with stoma placement, rheumatoid arthritis, diabetes mellitus, hypertension, right hip prosthesis placement. At the first visit to our hospita!, She had a remarkable erosion of the left ear canal, fistula was found in front of the ear canal skin. She showed pus leakage due to her chewing. Strongly swelling surrounded the left tonsil and soft palate, and oropharynx had been narrowed. T he CT scan revealed the low density area with a contrast effect from the lower ear to the left tonsil, was diagnosed with left peritonsillar abscess. On admission to our hospital, drainage and the administration of antibiotics were performed. She was discharged in satisfactory progress on day 10. Peritonsillar abscess, but there is a frequently encountered disease, being the chief complaint otorrhea is rare. As reported case seems to be similar as far as we have searched is only reported as "one case of deep neck abscess in the throat and ear canal causing self-destruction" is Tomohiro Anno 1961. We report this case with the literature about peritonsillar abscess. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=大道亮太郎 kn-aut-sei=大道 kn-aut-mei=亮太郎 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=片岡祐子 kn-aut-sei=片岡 kn-aut-mei=祐子 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=石原久司 kn-aut-sei=石原 kn-aut-mei=久司 aut-affil-num=3 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=西ｱ和則 kn-aut-sei=西ｱ kn-aut-mei=和則 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院 医歯薬学総合研究科 耳鼻咽喉・頭頸部外科学 affil-num=2 en-affil= kn-affil=岡山大学大学院 医歯薬学総合研究科 耳鼻咽喉・頭頸部外科学 affil-num=3 en-affil= kn-affil=香川労災病院耳鼻咽喉科・頭頸部外科 affil-num=4 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科耳鼻咽喉・頭頸部外科学 END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=3 article-no= start-page=241 end-page=243 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Guidelines for acute otitis media in children kn-title=小児急性中耳炎診療ガイドライン en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KataokaYuko en-aut-sei=Kataoka en-aut-mei=Yuko kn-aut-name=片岡祐子 kn-aut-sei=片岡 kn-aut-mei=祐子 aut-affil-num=1 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name=西ｱ和則 kn-aut-sei=西ｱ kn-aut-mei=和則 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　耳鼻咽喉・頭頸部外科学 affil-num=2 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　耳鼻咽喉・頭頸部外科学 END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=13 article-no= start-page=652 end-page=654 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20110914 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Expression analysis of microRNAs in murine cochlear explants en-subtitle= kn-subtitle= en-abstract= kn-abstract=MicroRNAs (miRNAs) play functional roles in sound transduction in cochlea. This study focuses on the validity of cochlear culture as an in vitro experimental tool, in view of miRNA expression. E15 cochleae were dissected and maintained in vitro for 48 h before extraction of miRNAs. MiRNA expression was comprehensively screened in explanted cochleae using a miRNA array that covers 380 miRNAs. A strong correlation was observed between expression levels of miRNAs in in vitro and in in vivo cochleae. Levels of 43 miRNAs were altered in vitro and these changes were reproducible over three trials. These findings indicate that in vitro miRNA profiling is a viable method for analysis of gene expression and action of chemical compounds on cochleae. en-copyright= kn-copyright= en-aut-name=HiraiMisato en-aut-sei=Hirai en-aut-mei=Misato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaYukihide en-aut-sei=Maeda en-aut-mei=Yukihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukushimaKunihiro en-aut-sei=Fukushima en-aut-mei=Kunihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugayaAkiko en-aut-sei=Sugaya en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KataokaYuko en-aut-sei=Kataoka en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharm, Dept Otolaryngol Head & Neck Surg affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharm, Dept Otolaryngol Head & Neck Surg affil-num=3 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharm, Dept Otolaryngol Head & Neck Surg affil-num=4 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharm, Dept Otolaryngol Head & Neck Surg affil-num=5 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharm, Dept Otolaryngol Head & Neck Surg affil-num=6 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharm, Dept Otolaryngol Head & Neck Surg en-keyword=embryonic cochlea kn-keyword=embryonic cochlea en-keyword=microRNA array kn-keyword=microRNA array en-keyword=organ culture of cochlea kn-keyword=organ culture of cochlea END start-ver=1.4 cd-journal=joma no-vol=124 cd-vols= no-issue=2 article-no= start-page=155 end-page=159 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Approaches for infantile hearing loss：Transmission from Okayama to other prefectures kn-title=小児難聴に対する取り組み―岡山から全国への発信― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KataokaYuko en-aut-sei=Kataoka en-aut-mei=Yuko kn-aut-name=片岡祐子 kn-aut-sei=片岡 kn-aut-mei=祐子 aut-affil-num=1 ORCID= en-aut-name=FukushimaKunihiro en-aut-sei=Fukushima en-aut-mei=Kunihiro kn-aut-name=福島邦博 kn-aut-sei=福島 kn-aut-mei=邦博 aut-affil-num=2 ORCID= en-aut-name=SugayaAkiko en-aut-sei=Sugaya en-aut-mei=Akiko kn-aut-name=菅谷明子 kn-aut-sei=菅谷 kn-aut-mei=明子 aut-affil-num=3 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name=西ｱ和則 kn-aut-sei=西ｱ kn-aut-mei=和則 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　耳鼻咽喉・頭頸部外科学 affil-num=2 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　耳鼻咽喉・頭頸部外科学 affil-num=3 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　耳鼻咽喉・頭頸部外科学 affil-num=4 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　耳鼻咽喉・頭頸部外科学 en-keyword=新生児聴覚スクリーニング検査 kn-keyword=新生児聴覚スクリーニング検査 en-keyword=小児難聴 kn-keyword=小児難聴 en-keyword=補聴器・人工内耳 kn-keyword=補聴器・人工内耳 en-keyword=言語発達 kn-keyword=言語発達 en-keyword=遺伝子診断 kn-keyword=遺伝子診断 END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=8 article-no= start-page=1343 end-page=1349 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20068 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Using assessment of higher brain functions of children with GJB2-associated deafness and cochlear implants as a procedure to evaluate language development en-subtitle= kn-subtitle= en-abstract= kn-abstract=

Objective: While investigators have reported that patients with GJB2-associated deafness and cochlear implants have preferable language development, the mechanisms of this phenomenon remains unknown. The goat of the present study was to assess higher brain functions of patients with GJB2-retated and GJB2-unrelated deafness as a method of evaluating language development.
Methods: Eight children with cochlear implants were subjected to genetic testing for GJB2 and underwent the Raven colored progressive matrices test, Rey's auditory verbal learning test, Rey's complex figure test, the standardized Language test for aphasia, the picture vocabulary test, and the standardized comprehension test for abstract words.
Results:Three children were diagnosed with GJB2-related deafness, and five children were diagnosed with GJB2-unrelated deafness. All three GJB2-related cases demonstrated normal range higher brain functions and fair language development. By contrast, one GJB2-unrelated case showed a semantic disorder, another demonstrated a visual cognitive disorder with dyslexia, and another had attention deficit-hyperactivity disorder.
Conclusions:Children with GJB2-unrelated deafness showed a high frequency of heterogeneous disorders that can affect proper language development. This difference between children with GJB2-retated and GJB2-unrelated deafness may account for the improved language development in children with GJB2-related deafness and cochlear implants. Further, genetic diagnosis of the non-syndromic hearing toss represents a useful tool for the preoperative prediction of outcomes following a cochlear implant procedure.
