A dermatophyte fungus infection of the feet known as tinea pedis or foot worm affects the soles and interdigitates clefts of the nails, and toes. Athlete’s foot is another name for it.
Trichophyton rubrum, a dermatophyte that was historically endemic to various regions of Africa, Asia, and Australia, is the culprit behind the infection. Today, though, the organism is still present throughout the Americas and Europe.
Epidemiology
Dermatophyte infections of the leg clefts may afflict ten percent of the general population. It is primarily blamed on wearing occlusive footwear for extended periods of time.
As the occurrence of tinea pedis is seen to be greater in patients using community baths, pools, and showers using sanitation facilities is likely to raise the odds of infection. Adult males are more likely than females to have the disease. One study found that the average age of onset was fifteen years.
Anatomy
Pathophysiology
Tinea pedis infection is likely caused by the blockage of foot clefts, maceration, and damp environments together with a growth in the microflora. This illness is influenced by skin deterioration, temperature, and humidity.
The fungus invaded the skin’s keratin layer by releasing keratinase enzymes. Additionally, mannans, which block the body’s immunological response, are found in the cell walls of dermatophytes.
Etiology
Trichophyton rubrum primarily causes tinea pedis. Additionally engaged are Epidermophyton floccosum and Trichophyton interdigitale. Tricholosporum violaceum is another sporadic agent. About 70% of the cases are caused by T. rubrum.
Risk elements consist of
a warm, muggy climate
Wearing occlusive shoes for a long time
Overly sweaty
Prolonged contact with water
Etiology
Genetics
Prognostic Factors
As long as safeguards are taken, the prognosis is favorable. A risk factor for tinea infestations is hyperhidrosis. The sufferer should be instructed to completely dry their toes after taking a bath because the disease frequently begins on the feet.
When reinfection is to be prevented, the pieces must be completely dry. After washing, it is highly recommended that vulnerable individuals apply a quality antiseptic powder to their feet, paying special attention to the area in between their toes, to keep it dry.
An effective dusting mixture for the foot is clotrimazole or tolnaftate powder. To maintain the feet dry, simply sprinkle talcum powder onto the shoes and socks. When wearing heated occlusive boots, periodic administration of topical antifungal treatment may be necessary.
