INTRODUCTION Cisplatin is an effective chemotherapeutic agent commonly used in the treatment of malignant tumours, but ototoxicity is a significant side effect. OBJECTIVES To discuss the mechanisms of cisplatin ototoxicity and subsequent cell death, and to present the results of experimental studies. MATERIAL AND METHODS We conducted a systematic search(More)
OBJECTIVES To determine the differences between tympanic and extratympanic electrodes regarding recording technique, comfort and ease of execution of the exam, and quality of auditory potential tracings. STUDY DESIGN Prospective cross-section investigation. METHODS Determination of the summation potential/action potential (SP/AP) ratio by(More)
Cisplatin is a potent antineoplastic drug widely used for the treatment of cancer in both adults and children. One of its most important side effects is ototoxicity, which leads to irreversible bilateral hearing loss for high frequencies (4-8 kHz). Several studies have tried to identify drugs that, when combined with cisplatin, may act as otoprotectors. The(More)
Aminoglycoside antibiotics cause considerable toxicity to the inner ear. A progressive hearing loss at high frequencies resulted from the loss of hair cells in the base of the cochlea and a constant preoccupation with finding a treatment that protects against their toxic effects. A self-protection phenomenon to high ototoxic doses of gentamicin is proposed(More)
Aminoglycoside antibiotic derivatives such as neamine, methyl neobiosaminide B, 2-deoxystreptamine, tetra-azidoneamine, tetra-N-acetylneamine, tetra-N-carboxy-benzylneamine, tetra-N-carboxy-methylneamine and tetra-p-methoxy-benzyliminoneamine were prepared and evaluated as to their cochlear and vestibular toxicity. Methyl neobiosaminide B, the most(More)
BACKGROUND muscle strength and power are two factors affecting balance. The impact of muscle strength and power on postural control has not been fully explored among different age strata over sixty. OBJECTIVES the aim of the present study was to assess the muscle strength and power of elderly women in different age groups and determine their correlation(More)
UNLABELLED The use of animal samples is important in otologic research and understanding the anatomy of their ears help make proper use of them in research projects. AIM to study guinea pig's and rat's ears under light microscopy(LM) and scanning electron microscopy(SEM) and understand their anatomical advantages in basic otologic research. MATERIALS(More)
UNLABELLED Hyperbaric oxygen therapy (HBOT) has enhanced the prevention and treatment of auditory ailments such as ototoxicity. OBJECTIVE To study the effects of HBOT upon ototoxic injuries produced by amikacin. METHOD This experimental study included 12 albino guinea pigs, whose auditory function was assessed through distortion product otoacoustic(More)
Auditory conditioning consists of the pre-exposure to low levels of a potential harmful agent to protect against a subsequent harmful presentation. The agent that was first tested was noise. This paradigm was more recently successfully tested with other agents. Nonetheless, the vast majority of the studies utilize the same agent to condition and to cause(More)
UNLABELLED The most common etiologies of tympanic membrane perforation are infections and trauma. OBJECTIVE The objective of the present study was to assess the healing of traumatic tympanic membrane perforation in rats. METHODS The tympanic membrane from male Wistar rats was perforated in the anterior and posterior portions to the handle of the(More)
