    Eosinophilic otitis media (EOM) is characterized by the presence of highly viscous middle ear effusion containing eosinophils, and is usually associated with bronchial asthma. Intratympanic corticosteroid administration and/or systemic steroid administration are effective treatments. However, the middle ear effusion and progressive hearing loss are difficult to control, significantly affecting the patient’s quality of life. Therefore, appropriate care is important not only for controlling the middle ear effusion and otorrhea, but also for preventing the progression of hearing loss. A 46-year-old woman was referred to our hospital with suspected eosinophilic otitis media. She had a history of asthma and aspirin sensitivity. In addition, she had recurrent nasal polyps despite having undergone nasal polypectomy on two occasions. She was diagnosed as having bilateral EOM according to the diagnostic criteria. She was started on steroid treatment, but after showing initial response, the middle ear effusion recurred immediately after withdrawal of steroid treatment. Although the patient also had difficulty in communication because of bilateral hearing loss, she could not wear hearing aids because of the middle ear effusion. Hearing aids sometimes aggravate middle ear infection by blocking aeration, increasing the risk of sensorineural hearing loss. Therefore, we implanted a bone-anchored hearing aid (Baha®) in her right ear. Average hearing threshold of 500, 1000 and 2000 was 35 dB using Baha®. Although audiometry revealed deterioration of the bone-conduction threshold in the right ear at five years after the Baha® implantation, she still had sufficient bone conduction hearing using Baha® because of the preserved bone-conduction in the contralateral ear. The Baha® hearing system is a clinically effective and good hearing rehabilitative device for patients with EOM.

    Bony abnormalities, including sphenoid dysplasia and calvarial defects, are well recognized in patients with neurofibromatosis type 1. However, having multiple calvarial defects is rare. We present a case of a 35-year-old Japanese male patient who was referred to our hospital because of hearing loss. He was diagnosed with neurofibromatosis type 1 during early childhood. Otoscopic examination revealed a protrusion from the anterior wall of the external auditory canal that obstructed the external auditory canal. Computed tomography findings revealed multiple defects and an uneven skull surface. Large bony defects of the anterior wall of the external auditory canal were also identified bilaterally. Conductive hearing loss was caused by temporomandibular joint herniation that was obstructing the external auditory canal in both ears. An active middle ear implant was implanted in the right ear. A floating mass transducer was placed into the round window niche using a round window coupler. The active middle ear implant improved postoperative audiometric thresholds to approximately 35 dB across all frequencies. No complications occurred for up to 30 months after the operation. An active middle ear implant is a feasible and valuable option for patients with neurofibromatosis type 1 and conductive hearing loss due to multiple skull defects that result in temporomandibular joint herniation.

    Objective: In Japan, the 57S and 67S single syllable lists have been used to test speech perception in cochlear implant (CI) users. However, due to advances in implants and processors, these lists have become too simple for CI users. In 2019, the Japan Otological Society created a new list, referred to as the iCI2004. The objective of this study was to compare the performance of these lists. Methods: The Japanese single syllable speech perception tests, iCI2004, 57S, and 67S, were administered to 70 patients with CI users. The effects of single syllable characteristics on the test scores were examined. The type and number of single syllables used in each list were different. Therefore, we compared the scores for normal lists, shared single syllables, and non-shared single syllables. Results: The average test results were 52% for iCI2004, 64% for 57S, and 77% for 67S; 67S performed the best, followed by 57S and iCI2004. The test results were significantly different. In a comparison of shared single syllables, the average scores were 58% for iCI2004 and 63% for 57S (45 pieces). A comparison of iCI2004 and 67S (17 pieces) showed that the average scores were 63% for iCI2004 and 75% for 67S. A comparison of 57S and 67S (20 pieces) showed that the average score for 57S was 70% and the average scored for 67S was 77%. No significant differences were detected under all conditions. Based on these results, the type of single syllable adopted affected the result. Conclusion: The data gives no clear indication that the selection of the word table or presentation of sound pressure affects listening to sound for CI users in Japan. Based on the type and number of single syllables used, iCI2004 seems appropriate for evaluation of hearing in patients using CI.

    There are few reports of the treatment for severe hearing loss due to otitis media with antineutrophil cytoplasmic antibody-associated vasculitis (OMAAV) achieved by cochlear implantation (CI). Here, we have reported the case of a patient with severe bilateral sensorineural hearing loss with low-frequency residual hearing by OMAAV. CI was performed in her right ear based on the results of contrast-enhanced magnetic resonance imaging (CE-MRI) and promontory stimulation test (PST). The residual hearing in her right ear was preserved after CI and utilized for combined electric acoustic stimulation (EAS). The combined EAS was used for 3 years until the residual hearing became stabilized. However, the usable hearing in low frequency worsened gradually, and the fitting strategy of cochlear implant was changed from combined EAS to CI alone 4 years after CI. Even when the speech discrimination score with CI no longer exceeds 50 %, the patient continued using CI because of its advantages in maintaining the quality of life of the patient. The combined EAS was found to be a feasible option even in an OMAAV patient with residual hearing. CE-MRI and PST may thus be helpful in deciding the side of CI surgery in a patient with OMAAV.

    We herein report the cytokine expression at different stages for three patients who developed cardiac complications after immune checkpoint inhibitor (ICI) therapy. Case 1 with biopsy-proven myocarditis showed increased levels of interleukin (IL)-8, monocyte chemotactic and activating factor, and granulocyte macrophage colony-stimulating factor (GM-CSF) when he developed Takotsubo cardiomyopathy. Case 2 with subclinical myocarditis showed predominant activation of IL-8 during the progressive clinical course. Case 3 with cytokine-releasing syndrome showed substantial activations of IL-6, IL-8, GM-CSF, and interferon-γ. Our data suggest the development of unique cytokine activation in individual patients with cardiac complications after ICI therapy.
