当科で施行した人工内耳埋込術 72 例について、「人工内耳埋込術後に何らかの追加の治療・処置を必要とした症状」を術後合併症と定義し、術後の合併症の有無について診療録の記載より調査を行った。72 例中 9 例(12.5%)に術後合併症を認めた。保存的治療もしくは経過観察のみで対処可能であった合併症(軽度合併症)は 4 例、観血的治療を必要とした合併症(重度合併症)は 5 例であった。軽度合併症の内訳は、味覚障害が 2 例、遅発性顔面神経麻痺が 1 例、人工内耳埋込部の感染が 1 例であった。また、重度合併症は、インプラント故障が 2 例、人工内耳埋込部の感染が 2 例、インプラントの露出が 1 例であった。このうち埋込部感染を認めた 2 例は、基礎疾患との関連が考えられた。インプラント故障を認めた 2 例においては、頭部打撲が原因であった。インプラントの露出を来した 1 例については、人工内耳埋込部と耳掛けの体外部との接触が原因と思われた。

<p> Past major earthquakes have been associated with an increase in the prevalence of vertigo or dizziness; the 2016 Kumamoto earthquakes on April 14 and 16 (JST, moment magnitude=7.0, Shindo 7 [Japanese seismic scale]) and the large numbers of aftershocks were no exception. Several months after the initial earthquake, significant outbreaks of vertigo or dizziness occurred over a large area surrounding the epicenter of the earthquake. However, it is unclear why major earthquakes cause these symptoms. After the major earthquake in Kumamoto, we conducted a questionnaire and medical records survey to investigate post-earthquake dizziness (PED). This survey covered a total of 575 subjects who complained of exacerbation of vertigo or dizziness after the earthquake and visited the hospital for follow-up before the scheduled dates. Our results showed that the number of patients with vertigo or dizziness who visited the hospital increased after the earthquake, and peaked between 2 and 4 weeks after the earthquake. The timing of onset of vestibular disorders varied according to the underlying disease. This study also suggested that earthquake-related psychological stress or stress resulting from earthquake evacuation could cause the onset of some vestibular disorders. We speculated that PED could be caused by stimulation of the vestibular and visual systems and bathyesthesia, psychological stress, potential effects of autonomic stress on the equilibrium function, and/or sensory mismatch. Our study could contribute to establishing PED as a new concept in the area of vestibular disorders.</p>

<p> Genetic defects are a major cause of hearing loss in newborns. Numerous causative genes for genetic hearing loss have been identified. Most genes cause only hearing loss which is referred to as non-syndromic deafness. On the other hand, some genes cause not only congenital hearing loss but also vestibular dysfunction,<i> etc</i>., which is referred to as syndromic deafness. However, presently, there are no truly curative treatments for this condition. One of the feasible treatments for congenital inner ear disease is "gene therapy during the embryonic stages" before the expression of abnormal morphology and function of the inner ear. In 2008, Gubbles et al. reported on gene transfer by transuterine-mediated injection into the embryonic inner ear (otocyst) and electroporation at embryonic day 11.5 (E11.5). We also utilized those methods, and performed electroporation-mediated transuterine gene transfer into otocysts (EUGO) for two models of congenital inner ear disease. One is the Connexin (Cx) 30 knockout (KO) mouse in which GJB6 gene coding Cx30 is deleted. The other is the pendrin KO mouse in which the SLC26A4 gene coding pendrin is deleted. The former is the model of non-syndromic deafness, the latter is the model of syndromic deafness. EUGO caused the vast expression of normal genes in the inner ear and successfully improved the hearing and vestibular function in both models. Although we utilized the otocyst at E11.5, this method must be demonstrated before the beginning of gene expression in the inner ear. Thus, the timing of embryonic gene therapy is important, because each gene has a different timing of expression in the inner ear. Herein, we describe state-of-the-art research on genetic inner ear disease treatment through gene therapy and discuss the obstacles to overcome in curative treatments of genetic inner ear diseases in humans.</p>
