| yellow nail | The complete or almost complete cessation of all nail growth, with thickening of the nails, increase in the convexity, loss of cuticles, and yellowing; the resulting onycholysis can cause loss of some of the nails; the condition is often associated with pulmonary disease but differs from clubbing in that the soft tissues are not hypertrophic. Synonym: yellow nail syndrome. (05 Mar 2000) |

| Kuntscher nail | An intramedullary nail used for internal fixation of a fracture. (05 Mar 2000) |
| fungal nail infection | The most common fungus infection of the nail is 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 tinea unguium and ringworm of the nails. (12 Dec 1998) |
