Age, drugs, and noise are major causes of acquired hearing loss. The involvement of reactive oxygen species (ROS) in hair cell death has long been discussed, but there is considerably less information available as to the mechanisms underlying ROS formation. Most cellular ROS arise in mitochondria and this review will evaluate evidence for mitochondrial pathology in general and dysfunction of th...
RP, a 52 years housewife was seen by us for the first time on 1st October, 2001. She had polyarticular pains and swelling since 20 years, involving small and large joints symmetrically. She had been diagnosed to suffer from rheumatoid arthritis and had received non-steroidal antiinflammatory drugs (NSAIDs), steroids and ayurvedic treatment intermittently over the past 20 years but had never rec...
Pain relievers containing N-acetyl-para-aminophenol, also called APAP, acetaminophen or paracetamol, in combination with opioid narcotics are top-selling pharmaceuticals in the U.S. Individuals who abuse these drugs for as little as sixty days can develop tinnitus and progressive bilateral sensorineural hearing loss. Recently published studies indicate that APAP and its metabolic product N-acet...
Untreated hearing loss imposes significant costs on the global healthcare system and impairs individuals' quality of life. Sensorineural is characterized by cumulative irreversible sensory hair cells auditory nerves in cochlea. Entire vital cochlear explants are one fundamental tools research to detect cell characterize molecular mechanisms inner ear cells. Many years ago, a protocol for neonat...
BACKGROUND Cisplatin is one of the most ototoxic chemotherapy drugs, resulting in a permanent and irreversible hearing loss in up to 50% of patients. Cisplatin and gentamicin are thought to damage hearing through a common mechanism, involving reactive oxygen species in the inner ear. Aspirin has been shown to minimise gentamicin-induced ototoxicity. We, therefore, tested the hypothesis that asp...
Ototoxic models of animal represent an elemental tool in basic otological research. In the present study, using guinea pigs we compared cochlear lesions mediated via cisplatin applied in terms of two regimens: consecutive application alone and in combination with furosemide. The influences of furosemide alone were also assessed; it was observed to result in temporary hearing loss and reversible...
An objective method for identifying ototoxic hearing loss among patients receiving cisplatin is necessary since the ability of patients to take a behavioral test may change over the course of treatment. Data from 56 monitoring visits by 19 Veterans taking cisplatin were used to identify combinations of distortion-product otoacoustic emission (DPOAE) metrics and ototoxicity risk factors that bes...
The Mongolian gerbil, Meriones unguiculatus, has been widely employed as a model for studies of the inner ear. In spite of its established use for auditory research, no robust protocols to induce ototoxic hair cell damage have been developed for this species. In this paper, we demonstrate the development of an aminoglycoside-induced model of hair cell loss, using kanamycin potentiated by the lo...
BACKGROUND Adverse events (AEs) of second line anti-tuberculosis drugs (SLDs) are relatively well documented. However, the actual burden has rarely been described in detail in programmatic settings. We investigated the occurrence of these events in the national cohort of multidrug-resistant tuberculosis (MDR-TB) patients in Nigeria. METHOD This was a retrospective, observational cohort study,...
Reactive oxygen species (ROS) play a major role in drug-, noise-, and age-dependent hearing loss, but the source of ROS in the inner ear remains largely unknown. Herein, we demonstrate that NADPH oxidase (NOX) 3, a member of the NOX/dual domain oxidase family of NADPH oxidases, is highly expressed in specific portions of the inner ear. As assessed by real-time PCR, NOX3 mRNA expression in the i...
