PREVIOUS AND NEXT TERMS--------------------------------------
Foot, athlete
A skin infection caused by a fungus called Trichophyton which can thrive and infect the upper layer of the skin when the feet (or other areas of the body) remain moist, warm, and irritated. The fungus can be found on floors and in socks and clothing and can be spread from person to person by contact with these objects. However, without proper growing conditions (a warm, moist environment), the fungus will not infect the skin.
Foot-and-mouth disease
A disease caused by a highly infectious virus that can infect people but affects them most by infecting livestock -- cattle, pigs, sheep and goats. The foot-and-mouth disease virus (FMDV) is in the same family of viruses as those causing the common cold.
Foot-drop
Dropping of the front of the foot due to weakness or paralysis of the anterior muscles of the lower leg. Foot-drop results in what is called a steppage gait in which the advancing foot is lifted high in order that the toes may clear the ground. Foot drop can be due to a number of conditions including injury to the muscles that dorsiflex the foot or to the nerves to those muscles, a neuropathy, multiple sclerosis, a stroke, drug toxicity, and diabetes. Treatment may include an ankle-foot orthosis.
