Tinea Pedis

Tinea pedis, also known as athlete's foot, is a fungal infection of the skin on the feet.

Causes and Risk Factors

• Tinea pedis is caused by a group of fungi called dermatophytes, which thrive in warm, moist environments.
• The most common causative organisms are Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum.
• Risk factors for developing tinea pedis include:
• Wearing tight or occlusive footwear
• Frequent exposure to moisture, such as sweating or walking in wet environments
• Sharing personal care items, such as towels or nail clippers
• Walking barefoot in public areas, such as swimming pools or locker rooms
• Weakened immune system

Symptoms

• Itching, burning, or stinging sensations on the skin of the feet
• Redness, scaling, or cracking of the skin
• Blisters or ulcers on the skin
• Foul odor from the feet
• Thickening of the skin on the feet, especially between the toes

Types of Tinea Pedis

• Interdigital tinea pedis: occurs between the toes
• Plantar tinea pedis: occurs on the soles of the feet
• Moccasin-type tinea pedis: occurs on the soles and sides of the feet, often with a moccasin-like distribution
• Vesiculobullous tinea pedis: occurs with blisters or ulcers on the skin

Diagnosis

• Physical examination of the affected area
• Scraping or swabbing of the affected area to collect samples for laboratory analysis
• Fungal culture or polymerase chain reaction (PCR) testing to confirm the presence of dermatophytes

Treatment

• Topical antifungal medications, such as clotrimazole, terbinafine, or miconazole
• Oral antifungal medications, such as griseofulvin or itraconazole, for more severe cases
• Keeping the feet clean and dry
• Changing socks regularly
• Using antifungal powders or sprays on the feet
• Wearing breathable footwear and socks

Prevention

• Practicing good foot hygiene, including washing the feet daily and drying them thoroughly
• Wearing breathable footwear and socks
• Avoiding sharing personal care items
• Avoiding walking barefoot in public areas
• Using antifungal powders or sprays on the feet regularly

Complications

• Bacterial infections, such as cellulitis or abscesses
• Fungal nail infections (onychomycosis)
• Spread of the infection to other parts of the body, such as the hands or groin area
