Tinea Versicolor

What is Tinea Versicolor?

A doctor’s evaluation is the best way to confirm a tinea versicolor infection. It is a relatively common condition.  Two to eight percent of the United States population has tinea versicolor disease.  This skin disease frequently affects adolescents and young adults, especially in warm humid climates.  It is thought that the yeast feeds on skin oils and dead skin cells.  Infections are found more often in people who have dandruff and hyperhidrosis.

Diagnoses for Tinea versicolor

Diagnosis is usually based on a medical history and physical examination. The patches or spots that appear with this condition are distinctive, and usually allow the diagnosis to be made on physical examination.  Physicians may use an ultraviolet light to examine the patches more clearly. Under the light yeast types in the Malassezia group may glow yellow-green.  Another common practice in tinea versicolor treatment is for the physician to do skin scrapings of the lesions to help confirm the tinea versicolor diagnosis.

For someone who has received a tinea versicolor diagnosis the infection is easily treated with a variety of things like skin creams, shampoos, or solutions. If the infection is severe or if it envelops large areas of your body, is recurring, or does not ease with skin care, the doctor may prescribe antifungal pills.  People with liver or heart problems cannot take antifungal pills.  Blood tests may have to be done so the doctor can check to make sure your kidneys and liver are functioning properly.

Tinea Versicolor Treatment

Tinea versicolor treatment kills the fungi quickly, but it can take months for the spots to abate and for your skin color to return to normal.  Tinea versicolor treatment can last days or weeks, depending on how the rash reacts. For six months after the first tinea versicolor treatment, a person may be advised to apply topical treatments occasionally or take one or more doses of oral antifungal medicine to help prevent the rash from returning.

Doctors often recommend that bed linens and pajamas be washed daily during the tinea versicolor treatment to avoid re-infection. Some experts do advise boiling or discarding contaminated clothing if the rash is unshakable to prevent tinea versicolor.  It is believed to be a more certain way to eliminate the yeast during the tinea versicolor treatment.

Griseofulvin Tinea Capitis

Griseofulvin Tinea Capitis

Tinea capitis, or ringworm of the scalp, is the most common dermatophyte infection among children.  This is a problem worldwide but approximately 3 to 8 percent of American children are affected, and up to one third of in-house contacts are asymptomatic carriers, meaning they show no outward signs of the infection. Tinea infections are usually spread by humans but may also be passed to humans from animals. Adolescent and adult infections are uncommon.

The three primary dermatophytes most commonly seen are Trichophyton tonsurans, Microsporum audouinii and Microsporum canis. Anti-fungal medications, taken by mouth, are used to treat the infection. There are several different options that are often used to treat this condition.  Griseofulvin has long been the standard therapy for tinea capitis.  It is currently the only antifungal agent labeled by the U.S. Food and Drug Administration for this condition. Griseofulvin is an antibiotic derived from a species of Penicillium.

Griseofulvin acts systemically to inhibit the growth of Trichophyton, Microsporum, and Epidermophyton genera of fungi. With the use of an anti-fungal like griseofulvin Tinea Capitis can be treated effectively.  Fungistatic amounts are deposited in the keratin, which is gradually exfoliated and replaced by non-infected tissue.  Griseofulvin absorption from the gastrointestinal tract varies considerably from one individual to the next. This is mainly because of insolubility of the drug in the upper G.I. tract. The peak serum level found in fasting adults given 0.5 gm occurs at about four hours and ranges between 0.5 and 2.0 mcg/mL.

As previously mentioned some individuals do not absorb at the same rate as others and tend to attain lower blood levels at all times. This may explain why some patients respond better to this type of treatment than others. Better blood levels can probably be attained in most patients if Griseofulvin is taken after ingesting a meal with a high fat content.

Some of the symptoms of tinea capitis or scalp ringworm to watch for are bald patched areas, where hair that has broken off from the scalp, itching of the scalp, pus-filled lesions or sores on the scalp, round, scaly lesions on the scalp that may be inflamed, and small black dots on the scalp. Tinea capitis may be extremely persistent, and it may return after treatment. It has been found that in many cases it goes away on its own as a person reaches puberty.  Good general hygiene is a key factor to prevent and treat tinea infections.

Most dermatophytes do not fluoresce. There are exceptions.  Two of those exceptions are zoophilic dermatophytes. Zoonotic means the disease can be passed from animals to humans.  Cats are more likely to be infected of all animals.  The skin changes in cats are very similar to those of affected people, but cats can carry the infection without exhibiting obvious signs.  It is sometimes hard to tell the source of the fungus.  Microsporum canis and Microsporum andoui are zoonotic minor causes fluoresce a blue-green color. A Wood’s light examination can also help to differentiate erythrasma caused by the bacterium Corynebacterium minutissimum from tinea cruris.  The former fluoresces coral-red and the latter does not fluoresce.

The Wood’s light examination can be helpful in evaluating the scope of infection, identifying areas for sampling and determining treatment response when the tinea capitis diagnosis is positive. The examination can also be helpful for examining the contacts of an infected person.

Microscopic examination is fundamental to the office diagnosis of any Tinea Capitis infection. A biopsy is scraped from an active area of the lesion, placed in a drop of potassium hydroxide solution and examined by microscope. The examination is highly for Tinea Capitis is sensitive and specific for dermatophyte identification but can be done quickly and easily,

If hyphae are identified in fungal infections and if pseudohyphae or yeast forms are seen in Candida or Pityrosporum infections, microscopy is positive. A positive examination is adequate to justify starting Tinea Capitis treatment.  Species identification does not usually influence treatment choices.

There are several different options that are often used to treat this Tinea Capitis condition.  Suggestions for prevention include things like keeping the area clean.   Using a medicated shampoo, with ingredients like ketoconazole or selenium sulfide, may reduce the spread of infection.  It may be necessary for other family members and pets to be examined, diagnosed and treated.
