Streptomycin, the first clinically used aminoglycoside is now used primarily in treating tuberculosis because many gram-negative bacteria are resistant and because of substantial ototoxicity. Streptomycin is now rarely used in the United States. Tobramycin is only rarely associated with ototoxicity (about 1/150 according to neu et al, 1986 but there is clear evidence that it can produce a vestibular syndrome similar to gentamicin (Barrsma, 1979; Lehmann, 1976). Most cases of Tobramycin toxicity have occurred in persons with renal impairment. There has been little ototoxicity seen in persons with repeated dosing (Pedersen et al, 1987; Thomesen et al, 1979 which suggests that it may be handled differently by the ear. It is suspected that tobramycin is ototoxic to hearing in neonates but there is little evidence to prove this(de hoog et al, 2002; 2003). In animals, tobramycin is much less ototoxic than gentamicin (Bamonte et al, 1986; Kitasato, 1990; McCormick et al, 1985; Petorossi et al, 1986). Vancomycin, by itself, appears to have only minor ototoxicity, but it potentiates the ototoxicity of gentamicin as well as (probably) other aminoglycosides such as Tobramycin.

It is collagen now used mainly topically because of renal toxicity and ototoxicity (to hearing). Neomycin is poorly absorbed from the normal gastrointestinal tract - about 97 is excreted in the feces. Neomycin is quickly and almost totally absorbed from body surfaces (except the urinary bladder) after bijenkorf local irrigation and when applied topically in association with surgical procedures. With repeated dosing, progressive accumulation occurs in the inner ear. Release occurs slowly over several weeks after dosing has been stopped. Hearing ototoxicity from oral absorption of neomycin has been reported (Rappaport et al, 1986) and there may also be toxicity from ear drops in patients with perforated ear drums. This issue is still unsettled (as of 12/1/98). Neomycin toxicity is often delayed in onset and may not be noted until long after neomycin has been discontinued (Information primarily from the manufacturers literature, teva pharmaceuticals, 11/1999). Kanamycin, also an aminoglycoside, was developed in 1957, and has been replaced by newer aminoglycosides such as gentamicin, tobramycin, netilmicin, and amikacin. It is not thought to be as ototoxic as neomycin. Minocycline in large doses is associated with dizziness, sometimes attributed to vestibular side effects.

persons with gentamicin toxicity have hearing appropriate for their age. Certain persons with mitochondrial deletions in the 12S subunit are much more susceptible to gentamicin than the general population. Commercial tests are presently available to detect this deletion (the A1555 deletion). The prevalence of this mutation is not clear, but 1-2 of the population is estimated based on available data. It is likely that there are many other genetic mutations that confer susceptibility, so far undocumented by present day medicine. Neomycin, another aminoglycoside, was isolated in 1949.

The toxicity of cisplatin is synergistic with gentamicin, and high doses of cisplatin have been reported to review cause total deafness. In animals, cisplatin ototoxicity is related to lipid peroxidation and the use of antioxidant agents such as vitamin e are protective (Rybak et al, 2000; Kalkanis et al, 2004). There are many chemotherapy agents which have no credible evidence for ototoxicity, and also many in whom there are single case reports of dubious significance. In general, drugs that are "broad" in their effects on the body would be expected to also have some ototoxicity. Drugs that are very narrow, perhaps aimed at cell markers, would not be reasonably expected to be ototoxic. Some chemotherapy drugs are used in treatment of inner ear disease -. Cytoxin, methotrexate, and Enbrel. These would obviously not be expected to be ototoxic. Gentamicin is presently the biggest problem antibiotic with respect to ototoxicity as most of the other ototoxic antibiotics have been replaced.

    Furthermore, even if we did have clear and unambiguous knowldge of all safety levels for all toxins, because so many substances are often used in combinations, the environmental and biological effects this cocktail might have, together with their toxicity, is largely not known, and perhaps. The known animal carcinogen acrylamide is generated in fried or overheated carbohydrate foods (such as french fries and potato chips bbq food (e.g. Health experts have criticized media reporting of the mmr-autism controversy for triggering a decline in vaccination rates. Presumably the focus is on reducing the number of unscheduled/emergency visits to the state-sponsored dentists.

    Modern cans use tin coated stainless steel rather than wrought iron. This bacterial strain is especially heat resistant, and is normally killed by heat treatment of canned foods at 121C for 3 minutes.

    Lead, for example, derives from a variety of sources including leaded gas, canned goods, old artist paints with lead-pigment, newsprint and coloured adverts, hair dyes and rinses, dolomite, soft coal, leaded glass, pewter ware or jewelry, fertilisers, pesticides, pottery, cosmetics, tobacco smoke, air pollution, rubber. It is used to minimise bacterial growth inside certain canned food stuffs. Chronic exposure to inorganic arsenic is known to cause cancer and has been linked to heart disease, diabetes and declines in brain functions. In addition, when these harmful micro-organisms are killed off, they release Endotoxins (those toxins not normally excreted by the bacteria/parasites but contained within their structure).
