TINEA

We've probably all had it or at least know someone who has. Tinea refers to a group of fungal infections affecting the skin. During warmer months, the prevalence of tinea will accelerate as the infecting organisms thrive on warm and moist environments (such as the feet). Tinea pedis (tinea of the feet) is one of the commonest fungal infections of the skin. It is rare before puberty and generally presents in three main forms:

Interdigital: ("Athlete's Foot") in between the toes, this is the most common form of tinea pedis and is characterised by moist white tissue that often peels and erodes. The underlying skin is red and may weep.

Scaly: presents as widespread white scaling affecting mainly the soles and sides of the feet ("moccasin foot") but can spread to the top of the foot. This form usually has red spots, is very dry and itchy.

Vesicular: is the least common type of tinea pedis with little blisters commonly on the arch or sole of the foot. There is some redness and scaling involved and sometimes a brown discolouration is associated with this form of tinea pedis.

TREATMENT FOR TINEA PEDIS

The treatment for tinea pedis is dictated by the type and severity of tinea you have. It is best to seek advice from your podiatrist for the most effective therapy. Treatment generally involves the application of a topical treatment such as an antifungal cream but in severe cases, oral medications are required. It should be noted that creams should be used for at least fourteen days after you think the tinea has gone to ensure all dermatophytes have been eradicated. The most important aspect of the management of tinea is prevention as recurrence is common.

PREVENTION OF TINEA

Several easy steps can help you prevent recurrence or if you have tinea, help stop you spreading it to others.

• Wash feet daily with a mild soap and dry thoroughly
• Use thongs in communal showers and poolside
• Don't share towels or footwear
• Regularly disinfect the shower recess at home
• Wear cotton socks and shoes with adequate ventilation (i.e. avoid synthetic materials which don't allow the foot to breathe)
• Allowing shoes to dry after use (alternating footwear every second day)

If you are having difficulty in getting over an episode of tinea or should you have any further queries regarding this or any other dermatological condition affecting the feet, please contact your podiatrist at the Melbourne Sports Medicine Centre.
