Rule out nail involvement produced by dermatoses, such as psoriasis, atopic dermatitis, onychomycosis and lichen planus, which may present with an isolated symptom and lead to a false-positive diagnosis (Bennet 1975) in the absence of a thorough history and laboratory tests. 

All floor surfaces must be kept clean, dry, and free from protruding nails, splinters, loose boards, holes, or projections. Where wet processes are used, drainage must be maintained and false floors, platforms, mats, or other dry standing places must be provided where practical.
