| tinea unguium | The most common fungus infection of the nails (onychomycosis). Onychomycosis makes the nails look white and opaque, thickened, and brittle. Older women (perhaps because oestrogen deficiency may increase the risk of infection). And men and women with diabetes or disease of the small blood vessels (peripheral vacscular disease) are at increased risk. Artificial nails (acrylic or wraps ) increase the risk because when an artificial nail is applied, the nail surface is usually abraded with an emery board damaging it, emery boards can carry infection, and. Water can collect under the nail creating a moist, warm environment for fungal growth. Alternative names include ringworm of the nails and dermatophytic onychomycosis. (17 Dec 1998) |
