Athlete’s foot, also called Tinea Pedis, is a parasitic fungal infection of the epidermis of the human foot. The term “athlete’s foot” refers to the disease and not the organism (fungus) that causes it. Several different fungi, called dermatophytes, can cause tinea pedis. Moreover, a fungus species that causes athlete’s foot can also cause, for example, jock itch (tinea cruris). It is typically caused by a mold (but in some cases a yeast) that grows on the surface of the skin and then into the living skin tissue itself, causing the infection. It usually occurs between the toes, but in severely lasting cases may appear as an extensive “moccasin” pattern on the bottom and sides of the foot. The malady more commonly affects males than females. Tinea pedis is estimated to be the second most common skin disease in the United States, after acne. Up to 15% of the U.S. population may have tinea pedis.
Causes of Tinea (Athlete’s foot)
The body normally hosts a variety of saprotrophic micro-organisms that rapidly cause infection. Athlete’s foot is a layman’s description of a skin fungal infection, and is medically referred to as tinea pedis. It may be associated with several different fungi, including yeasts. The most common fungi causing tinea pedis are Trichophyton rubrum and T. mentagrophytes. Fungi that involve the skin are termed dermatophytes and the resulting infections are called dermatophytosis.
Symptoms of Tinea (Athlete’s foot)
Athlete’s foot causes scaling, flaking and itching of the affected skin. Blisters and cracked skin may also occur, leading to exposed raw tissue, pain, swelling and inflammation. Secondary bacterial infection can accompany the fungal infection, sometimes requiring a course of oral antibiotics.
The infection can be spread to other areas of the body, such as the armpits, knees, elbows, and the groin, and usually is called by a different name once it spreads (such as tinea corporis on the body or limbs and tinea cruris (jock itch or dhobi itch) for an infection of the groin. Tinea pedis most often manifests between the toes, with the webspace between the fourth and fifth digits most commonly afflicted.
Diagnosis for Tinea (Athlete’s foot)
Diagnosis can be performed by a pharmacist, general practitioner and by specialists of dermatologist or podiatrist.
Athlete’s foot can usually be diagnosed by visual inspection of the skin, but where the diagnosis is in doubt direct microscopy of a potassium hydroxide preparation (known as a KOH test) may help rule out other possible causes, such as eczema or psoriasis. A KOH preparation is performed on skin scrapings from the affected area. The KOH preparation has an excellent positive predictive value, but occasionally false negative results may be obtained, especially if treatment with an anti-fungal medication has already begun.
If the above diagnoses are inconclusive or if a treatment regimen has already been started, a biopsy of the affected skin (i.e. a sample of the living skin tissue) can be taken and histological examination of the tissue performed.
A Wood’s lamp, although useful in diagnosing fungal infections of the hair (Tinea capitis), is not usually helpful in diagnosing tinea pedis since the common dermatophytes that cause this disease do not fluoresce under ultraviolet light. However, it can be useful for determining if the disease is due to a non-fungal source.
Transmission from person to person
Athlete’s foot is caused by a parasitic fungus and is a communicable disease. It is typically transmitted in moist environments where people walk barefoot, such as showers, bath houses, and locker rooms. It can also be transmitted by sharing footwear with an infected person, or less commonly, by sharing towels with an infected person.
Transmission to other parts of the body
The various parasitic fungi that cause athlete’s foot can also cause skin infections on other areas of the body, most often under toenails (Onychomycosis) or on the groin (tinea cruris).
Prevention forTinea (Athlete’s foot)
The practices given in this section do not only help prevent spread of the fungus, they can also help greatly in managing and curing athlete’s foot in an individual by reducing or eliminating re-exposure to the fungus in one’s home environment.
The fungi that cause athlete’s foot can live on shower floors, wet towels, and footwear. Athlete’s foot is caused by a fungus and can spread from person to person from shared contact with showers, towels, etc. Hygiene therefore plays an important role in managing an athlete’s foot infection. Since fungi thrive in moist environments, it is very important to keep feet and footwear as dry as possible.
Prevention measures in the home
The fungi that cause athlete’s foot live on moist surfaces and can be transmitted from an infected person to members of the same household through secondary contact. By controlling the fungus growth in the household, transmission of the infection can be prevented.
- Spray tub and bathroom floor with disinfectant after each use to help prevent reinfection and infection of other household members.
- Wash sheets, towels, socks, underwear, and bedclothes in hot water (at 60 °C / 140 °F) to kill the fungus.
- Change towels and bed sheets at least once per week.
- Avoid sharing of towels, shoes and socks between household members.
- Use a separate towel for drying infected skin areas.
Use Anti-Fungal Soap
The use of a proper antibacterial and anti-fungal soap has been proven to aid in the prevention of athlete’s foot. Soaps such as “”GymSoap”” are designed to prevent contamination of the human body by infection and fungi such as athlete’s foot. Some of the active ingredients attributed to preventing these ailments include Tea Tree Oil, which contains terpinen-4-ol which is thought to be the cause of the antimicrobial activity seen in it, and has been noted for the successful treatment of fungal infections ; deionized water, beneficial for its lack of sediments and chlorine ; and Aloe Vera which helps in soothing, moisturizing and healing the skin as well as killing fungus .
Prevention measures in public places
- Wear shower shoes or sandals in locker rooms, public showers, and public baths.
- Wash feet, particularly between the toes, with soap and dry thoroughly after bathing or showering.
- If you have experienced an infection previously, you may want to treat your feet and shoes with over-the-counter drugs.
Personal prevention measures
- Dry feet well after showering, paying particular attention to the web space between the toes.
- Try to limit the amount that your feet sweat by wearing open-toed shoes or well-ventilated shoes, such as lightweight mesh running shoes.
- Wear lightweight cotton socks to help reduce sweat. These must be washed in hot water and/or bleached to avoid reinfection. New light weight, moisture wicking polyester socks, especially those with anti-microbial properties, may be a better choice.
- Use foot powder to help reduce moisture and friction. Some foot powders also include an anti-fungal ingredient.
- Wear open-toed shoes or simply light-weight socks without shoes when at home.
- Keep shoes dry by wearing a different pair each day.
- Change socks and shoes after exercise.
- Replace sole inserts in shoes/sneakers on a frequent basis.
- Replace old sneakers and exercise shoes.
- To prevent jock itch: When getting dressed, put on socks before underwear.
- After any physical activity shower with a soap that has both an antibacterial and anti fungal fighting agent in it.
Treatments of Tinea (Athlete’s foot)
There are many conventional medications (over-the-counter and prescription) as well as alternative treatments for fungal skin infections, including athlete’s foot. Important with any treatment plan is the practice of good hygiene. Several placebo controlled studies report that good foot hygiene alone can cure athlete’s foot even without medication in 30-40% of the cases. However, placebo-controlled trials of allylamines and azoles for athlete’s foot consistently produce much higher percentages of cure than placebo.
Conventional treatment typically involves daily or twice daily application of a topical medication in conjunction with hygiene measures outlined in the above section on prevention. Keeping feet dry and practicing good hygiene is crucial to preventing reinfection. Severe or prolonged fungal skin infections may require treatment with oral anti-fungal medication. Apply zinc oxide based diaper rash ointment.
The fungal infection is often treated with topical antifungal agents, which can take the form of a spray, powder, cream, or gel. The most common ingredients in over-the-counter products are miconazole nitrate (2% typical concentration in the United States) and tolnaftate (1% typ. in the U.S.). Terbinafine, marketed as Lamisil is another over-the-counter drug. There exists a large number of prescription antifungal drugs, from several different drug families. These include ketaconazole, itraconazole, naftifine, nystatin, caspofungin. One study showed that allylamines (terbinafine, Amorolfine, naftifine, butenafine) cure slightly more infections than azoles (Miconazole, ketaconazole, clotrimazole, itraconazole, sertaconazole, etc.). Undecylenic acid (a castor oil derivative) is a known fungicide that can be used for fungal skin infections such as athlete’s foot. Whitfield’s Ointment (benzoic and salicylic acid) is an older treatment that still sees occasional use.
Some topical applications such as carbol fuchsin (also known in the U.S. as Castellani’s paint), often used for intertrigo, work well but in small selected areas. This red dye, used in this treatment like many other vital stains, is both fungicidal and bacteriocidal; however, because of the staining it is cosmetically undesirable. For many years gentian violet was also used for bacterial and fungal infections between fingers or toes.
The time line for cure may be long, often 45 days or longer. The recommended course of treatment is to continue to use the topical treatment for four weeks after the symptoms have subsided to ensure that the fungus has been completely eliminated. However, because the itching associated with the infection subsides quickly, patients may not complete the courses of therapy prescribed.
Anti-itch creams are not recommended as they will alleviate the symptoms but will exacerbate the fungus; this is due to the fact that anti-itch creams typically enhance the moisture content of the skin and encourage fungal growth. For the same reason, some drug manufacturers are using a gel instead of a cream for application of topical drugs (for example, naftin and Lamisil). Novartis, maker of Lamisil, claims that a gel penetrates the skin more quickly than cream.
If the fungal invader is not a dermatophyte but a yeast, other medications such as fluconazole may be used. Typically fluconazole is used for candidal vaginal infections moniliasis but has been shown to be of benefit for those with cutaneous yeast infections as well. The most common of these infections occur in the web spaces (intertriginous) of the toes and at the base of the fingernail or toenail. The hall mark of these infections is a cherry red color surrounding the lesion and a yellow thick pus.
Oral treatment with griseofulvin was begun early in the 1950s. Because of the tendency to cause liver problems and to provoke aplastic anemia the drugs were used cautiously and sparingly. Over time it was found that those problems were due to the size of the crystal in the manufacturing process and microsize and now ultramicrosize crystals are available with few of the original side effects.
For severe cases, the current preferred oral agent in the UK, is the more effective terbinafine. Other prescription oral antifungals include itraconazole and fluconazole.
Symptomatic relief from itching may be achieved after topical application of tea tree oil, probably due to its involvement in the histamine response, however the efficacy of Tea tree oil in the treatment of athlete’s foot (achieving mycological cure) is questionable.
A study of the effect of 3% (v/v) aqueous onion extract was shown to be effective in laboratory conditions against Trichophyton mentagrophytes and T. rubrum.
Ajoene, a compound found in garlic, is sometimes used to treat athlete’s foot.
Rubbing alcohol, hydrogen peroxide and vinegar
Direct application of rubbing alcohol and/or hydrogen peroxide after bathing can aid in killing the fungus at the surface level of the skin and will help prevent a secondary (bacterial) infection from occurring. In addition, soaking the feet in a bath of 70% rubbing alcohol will help dry the skin out, and likewise kill the invading fungus. The alcohol is not, however, effective against spores. Vinegar in some cases has killed the fungus and is effective against spores.
Boric acid application in the socks is used to prevent athlete’s foot when recurrent infections occurs, but is not used to treat it.
Since fungi grow in moist conditions, it is very important to dry the feet well after bathing. A hair dryer can be used to aid the drying process, or to dry feet which have become slightly moist in between showers or baths.
Rubbing feet with a baking soda paste and/or sprinkling baking soda in shoes is thought to help by changing pH.
Household bleach (not recommended)
The use of household bleach as a direct topical application or soak for tinea pedis is not recommended, as it is a well documented irritant (clearly labelled in the United Kingdom as “Harmful” by COSHH). It is used diluted as an environmental decontaminatant to prevent the spread of dermatophytes between animals, and from animals to humans.
Some podiatrists recommend soaking the feet in a solution of Epsom salts in warm water.
The Oxford English Dictionary documents written usage of the term in 1928 (1928 Lit. Digest 22 December. 16/1), which seems to undercut the claim by W. F. Young, Inc. that the term “athlete’s foot” was originated, rather than simply popularized, as part of an advertising campaign for Absorbine Jr. during the 1930s.
Homeopathy Treatment for Tinea (Athlete’s foot)
Keywords: homeopathy, homeopathic, treatment, cure, remedy, remedies, medicine
Homeopathy treats the person as a whole. It means that homeopathic treatment focuses on the patient as a person, as well as his pathological condition. The homeopathic medicines are selected after a full individualizing examination and case-analysis, which includes the medical history of the patient, physical and mental constitution, family history, presenting symptoms, underlying pathology, possible causative factors etc. A miasmatic tendency (predisposition/susceptibility) is also often taken into account for the treatment of chronic conditions. A homeopathy doctor tries to treat more than just the presenting symptoms. The focus is usually on what caused the disease condition? Why ‘this patient’ is sick ‘this way’. The disease diagnosis is important but in homeopathy, the cause of disease is not just probed to the level of bacteria and viruses. Other factors like mental, emotional and physical stress that could predispose a person to illness are also looked for. No a days, even modern medicine also considers a large number of diseases as psychosomatic. The correct homeopathy remedy tries to correct this disease predisposition. The focus is not on curing the disease but to cure the person who is sick, to restore the health. If a disease pathology is not very advanced, homeopathy remedies do give a hope for cure but even in incurable cases, the quality of life can be greatly improved with homeopathic medicines.
The homeopathic remedies (medicines) given below indicate the therapeutic affinity but this is not a complete and definite guide to the homeopathy treatment of this condition. The symptoms listed against each homeopathic remedy may not be directly related to this disease because in homeopathy general symptoms and constitutional indications are also taken into account for selecting a remedy. To study any of the following remedies in more detail, please visit the Materia Medica section at www.Hpathy.com.
None of these medicines should be taken without professional advice and guidance.
