Purpose: The purpose of this study was to compare the levels of knowledge on 5 diseases between persons in hearing impaired and normal hearing groups. Method: The participants consisted of 44 people who are hearing impaired and 47 who are not. An instrument developed by the research team was used for data collection. The questionnaire consisted of 90 items including demographics and items on 5 diseases, hypertension, cancer, diabetes, pulmonary tuberculosis, and hepatitis. Results: The level of knowledge on the 5 diseases, hypertension, cancer, diabetes, pulmonary tuberculosis, and hepatitis in normal hearing group was significantly higher than hearing impaired group. Conclusion: More attention and comprehensive educational programs are needed for people with hearing impairment.

Genetic hearing loss crosses almost all the categories of hearing loss which includes the following: conductive, sensory, and neural; syndromic and nonsyndromic; congenital, progressive, and adult onset; high-frequency, low-frequency, or mixed frequency; mild or profound; and recessive, dominant, or sex-linked. Genes play a role in almost half of all cases of hearing loss but effective treatment options are very limited. Genetic hearing loss is considered to be extremely genetically heterogeneous. The advancements in genomics have been instrumental to the identification of more than 6,000 causative variants in more than 150 genes causing hearing loss. Identification of genes for hearing impairment provides an increased insight into the normal development and function of cells in the auditory system. These defective genes will ultimately be important therapeutic targets. However, the auditory system is extremely complex which requires tremendous advances in gene therapy including gene vectors, routes of administration, and therapeutic approaches. This review summarizes and discusses recent advances in elucidating the genomics of genetic hearing loss and technologies aimed at developing a gene therapy that may become a treatment option for in the near future.

Otosclerosis, a hereditary disorder characterized by disordered resorption and deposition of bone, results in progressive hearing loss. Osteogenesis imperfecta (OI) is a genetic disorder characterized by recurrent fractures, blue sclera, and varying degrees of hearing impairment; and is a known risk factor for otosclerosis. After adolescence, the risk of fracture decreases, reducing the need for follow-up in OI. However, otosclerosis is a progressive disorder. In this report, we discuss two cases of familial otosclerosis with different clinical features. We hypothesize that the difference in hearing level correlates with the difference in computed tomography findings. The mother, whose case was considered severe, was prescribed hearing aids, while the daughter, who had normal hearing level, was regularly followed up.

청각장애 아동은, 듣고 발화하는 과정을 통해 언어를 재구성해가는 건청 아동과는 달리, 청력의 손실로 인해 언어 습득의 선천적 메커니즘이 작용될 수 없다. 따라서 청각장애 아동의 언어능력 향상을 위해 웹 기반 언어학습 시스템은 이들의 언어학습 특성에 적합하게 구성되어야 한다. 청각장애 아동을 위한 웹 기반 언어학습 시스템을 설계할 때 동작이나 상황을 나타내는 말을 동적으로 구현하고, 사물 및 행동에 대한 관찰력을 증진시킬 수 있도록 주도적인 상황언어학습의 시스템 구성이 필요하다. 그리고 대체사고전략의 활용과 얼굴표정의 강조, 반대어와 대비어의 활용이 시스템 구성에 적용되어야 한다. 이 연구에서는 청각장애 아동의 문법적 오류의 감소와 언어학습의 향상을 도모할 수 있도록 이들의 특성에 적합한 언어학습 시스템을 제안한다.

The cochlear implantation(CI) as an useful tool for aural rehabilitation in bilateral severe to profound hearing impairment. However, CI prefer to usually one ear in spite of bilateral hearing impaired. because of the various characteristics of hearing loss, the hearing conservation for the future possibility, and socioeconomic condition of hearing impaired person and their families. The unilateral CI has limitations such as a directional loss, a difficult speech understanding in noise and a neural plasticity. These limitations will be overcome by hearing aid(HA) which is familiar with hearing impairer. but HA fitting for bimodal-binaural hearing are difficult because the difference output characteristic of HA and CI. This study will be confirm realities of use of HA in unilateral cochlear implantee. For this goal, 25(m:f=10:15) child participated who are used to HA for 1 to 17 months. We had telephone interviews with their mother about use of HA, change of auditory performance and own voice. As the results, hearing threshold levels of unimplanted ear, the use of a appropriate HA, implanted and aided hearing threshold level(HTL) are must be considered for successful biomodal-binaural hearing. Especially, implanted and aided HTL should be very useful parameter for a prediction of HA effect and a criterion of selection for bilateral cochlear implantation.

Because the psychophysical symptoms of hearing loss and dementia in the elderly are very similar, untrained healthcare professionals in dementia facilities can easily overlook a severity of hearing loss in their patients. The present study identifies their knowledge, attitudes, and practices (KAP) on hearing loss using a survey whether they may help hearing problem of the patients with dementia. A total of 29 health-care professionals responded to the KAP survey. Also, 2 family members participated. The results showed that most of the nurses and caregivers in elderly medical welfare facilities who worked with dementia patients did not have knowledge of their hearing loss. Even the facility managers did not know how to conduct hearing tests for their patients although they did recognize that some of their patients had a hearing loss. Eventually, actual practice was not possible at this moment by the professionals. However, our respondents did have a positive attitude toward screening for hearing loss and help their patients with dementia wear hearing aids if a clinical guideline was provided. We suggest to develop clear and precise clinical guidelines of the hearing screening test for the dementia patients due to the interrelationship between dementia and hearing loss. When these guidelines apply to elderly residents in a medical welfare facility, early diagnosis and treatment of their sensory loss will help alleviate their dementia as well.

The spontaneous mutant circling mouse (cir/cir) shows a circling behavior and hearing loss. We produced transgenic mice overexpressing transmembrane inner ear (tmie) gene, the causative gene, for the phenotypic rescue of the circling mouse. Through the continuous breeding with circling mice, the cir/cir homozygous mice carrying the transgene (cir/cir-tg) were produced. The rescued cir/cir-tg mice were able to swim in the water with proper orientation and did not show any circling behavior like wild type mice. Western blot and immunohistochemical analysis exhibited that the transgenic tmie was expressed in the inner ear. Inner and outer hair cells were recovered in the cochlea and spiral ganglion neurons were also recovered in the rescued mice. Auditory brainstem response (ABR) test demonstrated that the cir/cir-tg mice are able to respond to sound. This study demonstrates that tmie transgene can recover the hearing impairment and abnormal behavior in the circling mouse.
