Early diagnosis is challenging, and surgical resection is indispensable for a definitive diagnosis. We report the case of a 3-year-old boy diagnosed with middle-ear SGCh during the follow-up period for left-sided hearing loss discovered at newborn hearing screening (NHS). Long-term follow-up after the NHS result, subsequent computed tomography/magnetic resonance imaging, and surgical resection led to its relatively early diagnosis and treatment.No potential conflict of interest relevant to this article was reported.Okayama University Medical SchoolActa Medica Okayama0386-300X7762023Cochlear Implantation in the Poorer-Hearing Ear Is a Reasonable Choice589593ENRyotaroOmichiDepartment of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesShinKariyaDepartment of Otolaryngology-Head and Neck Surgery, Kawasaki Medial UniversityYukihideMaedaDepartment of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesKunihiroFukushimaHayashima Clinic of Otolaryngology and DermatologyYukoKataokaDepartment of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesAkikoSugayaDepartment of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesKazunoriNishizakiDepartment of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesMizuoAndoDepartment of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesOriginal Article10.18926/AMO/66150Choosing the optimal side for cochlear implantation (CI) remains a major challenge because of the lack of evidence. 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.No potential conflict of interest relevant to this article was reported.Department of Otolaryngology, Okayama University HospitalActa Medica Okayama2023Important things in school life for elementary, junior high, and high school students with hearing loss: 20 tips to support them better: Teacher’s Edition -simplified version-ENYukoKataokaDepartment of Otolaryngology, Okayama University Hospital10.18926/65475No potential conflict of interest relevant to this article was reported.Department of Otolaryngology, Okayama University HospitalActa Medica Okayama2023Communication Support for People with APD: Schools/WorkplacesENYukoKataokaDepartment of Otolaryngology, Okayama University Hospital10.18926/65474No potential conflict of interest relevant to this article was reported.Okayama University Hospital Hearing Health CenterActa Medica Okayama2023Important things in school life for elementary, junior high, and high school students with hearing loss (Teacher’s Edition)ENYukoKataokaOkayama University Hospital Hearing Health CenterAtsukoNakagawaOkayama University Hospital Hearing Health Center10.18926/65473No potential conflict of interest relevant to this article was reported.岡山大学病院 耳鼻咽喉科Acta Medica Okayama2022難聴をもつ小・中・高校生の学校生活で大切なこと : 難聴児への関わり方がよく分かる20のヒント : 先生編, 1枚で理解できる！簡略版ENYukoKataoka10.18926/63370No potential conflict of interest relevant to this article was reported.岡山大学病院 耳鼻咽喉科Acta Medica Okayama2022APDの方へのコミュニケーション支援 : 学校・職場編ENYukoKataoka10.18926/63051No potential conflict of interest relevant to this article was reported.岡山大学病院 耳鼻咽喉科Acta Medica Okayama2021難聴をもつ小・中・高校生の学校生活で大切なこと : 先生編ENYukoKataokaAtsukoNakagawa10.18926/61938No potential conflict of interest relevant to this article was reported.日本耳鼻咽喉科感染症研究会Acta Medica Okayama091339763112013耳漏を主訴に来院した扁桃周囲膿瘍の1例175178EN
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.No potential conflict of interest relevant to this article was reported.岡山医学会Acta Medica Okayama0030-155812632014小児急性中耳炎診療ガイドライン241243ENYukoKataokaKazunoriNishizakiNo potential conflict of interest relevant to this article was reported.Acta Medica Okayama0959-496522132011Expression analysis of microRNAs in murine cochlear explants652654ENMisatoHiraiYukihideMaedaKunihiroFukushimaAkikoSugayaYukoKataokaKazunoriNishizakiMicroRNAs (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.No potential conflict of interest relevant to this article was reported.岡山医学会Acta Medica Okayama0030-155812422012小児難聴に対する取り組み―岡山から全国への発信―155159ENYukoKataokaKunihiroFukushimaAkikoSugayaKazunoriNishizakiNo potential conflict of interest relevant to this article was reported.Acta Medica Okayama7082006Using assessment of higher brain functions of children with GJB2-associated deafness and cochlear implants as a procedure to evaluate language development13431349ENAkihiroKawasakiKunihiroFukushimaYukoKataokaShoichiroFukudaKazunoriNishizaki<p><b>Objective:</b> 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.<br />
<b>Methods:</b> 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.<br />
<b>Results:</b>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.<br />
<b>Conclusions:</b>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.</p>No potential conflict of interest relevant to this article was reported.Acta Medica Okayama2002Chondroitin Sulfate Proteoglycan at the Basal Lamina Beneath High Endothelial Cells in Human Palatine Tonsils: A Light and Electron Microscopic Study Using the Cationic Colloidal Iron MethodENNo potential conflict of interest relevant to this article was reported.
