Athlete's foot (Tinea pedis) is the most prevalent
cutaneous fungal infection in human that is common
in adult transmitted in moist or humid locations.
•
Location: Classically, the toes are involved, the web
space between the fourth and fifth toes being the most
commonly affected. More severe infections may
spread to the sole of the foot and even to the upper
surface in some cases that need referral.

The skin in the web spaces appears white and (soggy).
The area is normally itchy and the feet tend to smell.
The skin become macerated and begin to peel off and
the underneath skin usually reddened and may be sore.
Severity:
Severe athlete's foot [broken and macerated skin with
signs of bacterial involvement (weeping, pus or yellow
crusts) required referral

1-Clean the skin daily with soap and water. Dry the skin
thoroughly after bath. Don’t share personal towel.
2-Socks should frequently change and washed regularly.
Cotton sock can facilitate the evaporation of moisture,
whereas nylon socks not.
3-Avoid wearing occlusive, non-breathable shoes in
summer, open toe sandals can be helpful and shoes
should be left off where possible.
4-
Applying antifungal foot powder daily can protect
against athletets infection
Management
Topical Antifungals generally advise use for 1–2 weeks
after the disappearance of all signs of infection
1-
Azoles (e.g. clotrimazole, ketoconazole and
miconazole)
Topical azoles can be used to treat many topical fungal
infections, including athlete’s foot.
They have a wide spectrum of action and have been
shown to have both antifungal and antibacterial activity.
So its useful for secondary infection.
SE: cause mild irritation of the skin
Tolnaftate
•
Available in powder, cream, aerosol and
solution formulations and is effective against
athlete’s foot.
•
It has antifungal, but not antibacterial, action.
•
It should be applied twice daily and treatment
should be continued for up to 6 weeks.
•
SE: Tolnaftate may sting slightly when applied
to infected skin.
Terbinafine
•
cream, solution, spray and gel formulations.
•
There is evidence that terbinafine is better than the
azoles in preventing recurrence, so it will be useful
for frequent athlete’s foot.
•
Terbinafine can cause redness, itching and stinging of
the skin;
•
contact with the eyes should be avoided.
•
Terbinafine products are not recommended for use in
children
.
Antifungal/steroid combination:
1-
Miconazole 2% with hydrocortisone 1% (Daktacort)
2- Clotrimazole 1% with Hydrocortisone 1% (Canesten-
H)
M
aximum period of treatment is 7 days. After that
continue with topical antifungal
•
Note: Topical steroid alone not recommended.
Why?
Athlete's foot, a common fungal infection, primarily affects the toes and can spread to the sole of the foot. Symptoms include white, itchy skin with a sogginess and odor. Severe cases with broken skin and signs of bacterial infection require referral. Prevention involves practicing good hygiene, changing socks regularly, wearing breathable shoes, and using antifungal foot powder. Treatment with topical antifungals like azoles is recommended for a couple of weeks. Referral may be needed for immunocompromised patients, diabetics, and toenail involvement.
