Corns, athletes

Athlete s foot, tinea pedis, is a condition caused by a fungus. Management of athlete s foot lies with the use of antifungal preparations such as clotrimazole (an imidazole antifungal) and tolnaftate. Salicylic acid is a keratolytic agent indicated for use in treatment of corns, calluses and warts. 

Salicylic acid is used to treat various hyperkeratotic lesions like corns, warts, ring- worm, athlete s foot, chronic dermatitis etc. 

The applications of these dosage forms can be used for their physical effects, in that they act as protectants, lubricants, emollients, drying agents, and such. They may also be used for the specific effect of the medicinal agent present. Preparations that are sold over-the-counter (OTC) often must contain a mixture of medicinal substances for the treatment of minor skin infections, itching, burns, diaper rash, insect stings and bites, athlete s foot, corns, calluses, warts, dandruff, acne, psoriasis, eczema, pain, arthritis, and to supply warmth to aching joints. 

Occupational marks represent the effects of a particular occupation on a worker s skin. They are usually calluses or corns that develop in locations subjected to repeated friction, pressure, or other trauma, and include discolorations, telangiectases, tattoos, odors, deformities, and other changes. In some occupations, the marks may be quite variable, as with musicians (Harvell and Maibach 1992). Corresponding marks may be seen in athletes (Kanerva 1998). Such marks were common previously among workers and served to identify many occupations. Today, with increasing automation, less frequent manual operation of tools.

Prevention of calluses and corns focuses on identifying rare predisposing correctable biomechanical problems and wearing cushioned pads to redistribute pressure. Calluses can be treated early with topical salicylic acid. Corns and advanced calluses, however, should be pared after hydration with warm water. Surgical removal of the underlying bony protuberances, which may be required, poses a particular challenge for the athlete because of lost time.
