Ototoxic Effects of Middle Ear Gentamicin Instillation in the Chinchilla
Gentamicin sulphate is used clinically to produce vestibular organ damage in patients with intractable vertigo. The drug is given locally by middle ear instillation. In humans, gentamicin appears to have a more toxic effect on the vestibular parts of the inner ear than on the cochlea. However, cochlear effects are not insignificant and to further explore the utility of monitoring vestibular and...
متن کاملBacterial otitis media, the chinchilla middle ear, and biofilms.
Otitis media in children has a significant impact on heath care and health-care economics [1]. It is the number one reason children are seen in physicians’ offices and the most common reason children are given antibiotics [2]. The economic impact was estimated in 1998 to be between $3 billion and $5 billion per year in the United States. This estimate does not take into consideration the indire...
متن کاملAnalyzing reverse middle-ear transmission: noninvasive Gedankenexperiments.
The phenomenological framework outlined in the companion paper [C. A. Shera and G. Zweig, J. Acoust. Soc. Am. 92, 1356-1370 (1992)] characterizes both forward and reverse transmission through the middle ear. This paper illustrates its use in the analysis of noninvasive measurements of middle-ear and cochlear mechanics. A cochlear scattering framework is developed for the analysis of combination...
متن کاملDetection of otoacoustic emissions in chinchilla when the middle ear contains amniotic fluid.
OBJECTIVES/HYPOTHESIS Otoacoustic emissions have frequently been used for newborn hearing screening. However, they have low specificities and high referral rates. The presence of amniotic fluid in the middle ear is one reason for these problems. The aim of this study was to determine the effects of human amniotic fluid on otoacoustic emissions and on middle-ear function. METHODS Forty-six chi...
متن کاملMiddle ear fluid cytokine and inflammatory cell kinetics in the chinchilla otitis media model.
Streptococcus pneumoniae is the most frequent microbe causing middle ear infection. The pathophysiology of pneumococcal otitis media has been characterized by measurement of local inflammatory mediators such as inflammatory cells, lysozyme, oxidative metabolic products, and inflammatory cytokines. The role of cytokines in bacterial infection has been elucidated with animal models, and interleuk...
