Arch - The arch of the foot is the area of the bottom of the foot between the heel pad and toe pad.
Acrokeratosis verruciformis - a hereditary dermatosis characterized by the presence of numerous flat wart-like papules on the dorsal aspect of the hand, foot, elbow, and knee.
Ankle - the part of the leg just above the foot; the joint between the leg and the foot. It is a hinge joint formed by the junction of the tibia and fibula with the talus, or ankle bone. The bones are cushioned by cartilage and connected by a number of ligaments, tendons, and muscles that strengthen the joint and enable it to be moved. Because it is in almost constant use, the ankle is particularly susceptible to injuries, such as sprain and fracture. It is also often one of the first joints to be affected by arthritis or gout.
Ankle clonus - a series of abnormal reflex movements of the foot, induced by sudden dorsiflexion, causing alternate contraction and relaxation of the triceps surae muscle.
Athlete's foot - a fungal infection of the skin of the foot; called also tinea pedis. It causes itching and often blisters and cracks, usually between the toes. Causative agents are Candida albicans, Epidermophyton floccosum, and species of Trichophyton, which thrive on warmth and dampness. If not arrested, it can cause a rash and itching in other parts of the body as well. It is likely to be recurrent, since the fungus survives under the toenails and reappears when conditions are favorable. Although Athlete''s foot is usually little more than an uncomfortable nuisance, its open sores provide excellent sites for more serious infections. Early treatment and health care supervision insure correct diagnosis and prevention of complications. Specific diagnosis is made by microscopic examination or culture of skin scrapings for the fungus.
Many people don't realize they have a fungal nail problem and, therefore, don't seek treatment. Yet, fungal toenail infections are a common foot health problem and can persist for years without ever causing pain. The disease, characterized by a change in a toenail's color, is often considered nothing more than a mere blemish. Left untreated, however, it can present serious problems.
Also referred to as onychomycosis, fungal nails are infections underneath the surface of the nail, which may also penetrate the nail. Fungal nail infections are often accompanied by a secondary bacterial and/or yeast infection in or about the nail plate, which ultimately can lead to difficulty and pain when walking or running. Symptoms may include discoloration, brittleness, loosening, thickening, or crumbling of the nail.
A group of fungi, called dermophytes, easily attack the nail and thrive on keratin, the nail's protein substance. In some cases, when these tiny organisms take hold, the nail may become thicker, yellowish-brown, or darker in color, and foul smelling. Debris may collect beneath the nail plate, white marks frequently appear on the nail plate, and the infection is capable of spreading to other toenails, the skin, or even the fingernails.
Nail bed injury may make the nail more susceptible to all types of infection, including fungal infection. Those who suffer chronic diseases, such as diabetes, circulatory problems, or immune-deficiency conditions, are especially prone to fungal nails. Other contributory factors may be a history of Athlete's Foot or excessive perspiration.
You can prevent fungal nail infections by taking these simple precautions:
- Exercise proper hygiene and regularly inspect your feet and toes.
- Keep your feet clean and dry.
- Wear shower shoes in public facilities whenever possible.
- Clip nails straight across so that the nail does not extend beyond the tip of the toe.
- Use a quality foot powder (talcum, not cornstarch) in conjunction with shoes that fit well and are made of materials that breathe.
- Avoid wearing excessively tight hosiery, which promotes moisture. Socks made of synthetic fiber tend to "wick" away moisture faster than cotton or wool socks, especially for those with more active lifestyles.
- Disinfect home pedicure tools and don't apply polish to nails suspected of infection.
Depending on the type of infection you have, over-the-counter liquid antifungal agents may not prevent a fungal infection from recurring. A topical or oral medication may need to be prescribed, and the diseased nail matter and debris removed, a process called debridement. Note: Please consult your physician before taking any medications.
In severe cases, surgical treatment may be required to remove the infected nail. Permanent removal of a chronically painful nail, which has not responded to any other treatment, permits the fungal infection to be cured and prevents the return of a deformed nail.
