Ringworm

Ringworm is a common fungal infection of the skin also be referred to as dermatophyte infection. The name ringworm is a misnomer since the disease is notcaused by a worm. More common in males than in females, ringworm is characterized by patches of rough, reddened skin. Raised eruptions usually form the circular pattern that gives the condition its name. As lesions grow, the centers start to heal; however, the inflamed borders expand and spread the infection.

Ringworm is a term that is commonly used to encompass several types of fungalinfection. Sometimes, however, only body ringworm is classified as true ringworm. Body ringworm (tinea corporis) can affect any part of the body except the scalp, feet, and facial area where a man's beard grows. The well-defined, flaky sores can be dry and scaly or moist and crusty.

Scalp ringworm (tinea capitis) is most common in children. It causes scaly, swollen blisters or a rash that looks like black dots. Sometimes inflamed and filled with pus, scalp ringworm lesions can cause crusting, flaking, and round bald patches, and can cause scarring and permanent hair loss.

Ringworm of the groin (tinea cruris or jock itch) produces raised redsores with well-marked edges. It can spread to the buttocks, inner thighs, and external genitals.

Ringworm of the nails (tinea unguium) generally starts at the tip of one or more toenails, which gradually thicken and discolor. The nail may deteriorate or pull away from the nail bed. Fingernail infection is far less common.

Ringworm can be transmitted by infected people or pets; or by towels, hairbrushes, or other objects contaminated by the fungi. Diabetes mellitus increasessusceptibility, as do dampness, humidity, and dirty, crowded living areas. Tightly braided hair and using hair gel also raise the risk. Likelihood of infection can be lessened by avoiding contact with infected people, pets, or contaminated objects; and staying away from hot, damp places.

Symptoms include inflammation, scaling, and sometimes itching. Diagnosis is based on microscopic examination of scrapings taken from lesions. A dermatologist may also study the scalp of a patient with suspected tinea capitis underultraviolet light. While some infections disappear without treatment, othersrespond to such topical antifungal medications as naftifine (Caldesene Medicated Powder) or tinactin (Desenex) or to griseofulvin (Fulvicin), which is taken by mouth. Medications should be continued for two weeks after lesions disappear.

A person with body ringworm should wear loose clothing and check daily for raw, open sores. Wet dressings applied to moist sores two or three times a daycan lessen inflammation and loosen scales, and the doctor may suggest placingspecial pads between folds of infected skin. Anything the patient has touched or worn should be sterilized in boiling water. Infected nails should be cutshort and straight and carefully cleared of dead cells with an emery board.Patients with jock itch should:

  • Wear cotton underwear and change it more than once a day
  • Keep the infected area dry
  • Apply antifungal ointment over a thin film of antifungal powder.

Shampoo containing selenium sulfide can help prevent spread of scalp ringworm, but prescription shampoo or oral medication is usually needed to cure the infection.

Among the homeopathic medicine recommended includes:

  • Sepia forbrown, scaly patches
  • Tellurium for prominent, well-defined, reddish sores
  • Graphites for thick scales or heavy discharge
  • Sulphur for excessive itching.

Topical applications of antifungal herbs and essential oils also can help resolve ringworm. Tea tree oil (Melaleuca spp.), thuja (Thuja occidentalis), and lavender (Lavandula officinalis) are the most common. Two drops of essential oil in 1/4 ounce of carrier oil is the dose recommendedfor topical application. Essential oils should not be applied to the skin undiluted. Botanical medicine can be taken internally to enhance the body's immune response. A person must be susceptible to exhibit this overgrowth of fungus on the skin. Echinacea (Echinacea spp.) and astragalus (Astragalus membranaceus) are the two most common immune-enhancing herbs. A well-balanced diet, including protein, complex carbohydrates, fresh fruits and vegetables, and good quality fats, is also important in maintaining optimal immune system function.

Ringworm can usually be cured, but recurrence is common. Chronic (recurring)infection develops in one patient in five.

It can take 6-12 months for new hair to cover bald patches, and 3-12 months to cure infected fingernails. Toenail infections do not always respond to treatment.
