Two side effects which limit the use of cisplatin in cancer chemotherapy are severe nephrotoxicity and ototoxicity. The concurrent administration of sodium thiosulfate with cisplatin reportedly protects from cisplatin nephrotoxicity, however, protection from ototoxicity has not been documented. The purpose of this study was to examine the efficacy of using thiosulfate to ameliorate the ototoxic...

Ototoxic hearing loss is usually detected earliest through monitoring of the highest audible frequencies in individuals administered ototoxic medications. Conducting ototoxicity monitoring may require testing patients in the hospital room. This study evaluated the use of insert earphones for obtaining reliable threshold responses at bedside. Twenty adult subjects were tested during two differen...

Treatment with cisplatin-containing chemotherapy regimens causes hearing loss in 40-60% of cancer patients. It has been suggested that genetic variants in the genes encoding thiopurine S-methyltransferase (TPMT) and catechol O-methyltransferase (COMT) can predict the development of cisplatin-induced ototoxicity and may explain interindividual variability in sensitivity to cisplatin-induced hear...

Aminoglycoside antibiotics, including gentamicin, are widely used clinically in treatment of bacterial infections. Unfortunately, their side effects, especially nephrotoxicity and ototoxicity remain a problem. It is known that aminoglycoside antibiotics bind well to melanin biopolymer, but the relation between their affinity to melanin and ototoxicity is not well documented. The aim of this wor...

Aminoglycosides are widely used in the treatment of gram-negative bacillary infections, including intraabdominal infections. However, these drugs may produce side effects of nephrotoxicity and ototoxicity, particularly when there is volume depletion, shock, advanced age, or renal impairment (23), risk factors which are common in patients with intra-abdominal infection. The impact of treatment w...

The toxicity of netilmicin was compared with that of amikacin in a randomized, prospective trial in 90 adults with a variety of serious gram-negative infections. There was no instance of antibiotic-related nephrotoxicity in the group given amikacin and only one instance in the group given netilmicin. Cochlear toxicity, as measured by a change in audiogram, occurred in 4/14 (28.5%) of the amikac...

Hearing loss or ototoxicity is one of the major side effects associated with the use of the antibiotics, particularly aminoglycosides (AGs), which are the most commonly used antibiotics worldwide. However, the molecular and cellular events involved in the antibiotic-induced ototoxicity remains unclear. In the present study, we test the possibility that prestin, the motor protein specifically ex...
