Dermatophyte infection is a superficial fungal infection of skin, hair and nails. It is also known as ringworm. In Hindi it is termed as Daad and in Marathi it is termed as Gachkaran.
Ringworm occurs when a person gets infected with Dermatophytes which is a superficial fungus. This fungus lives off human keratin and that is why the infection can occur on the skin, hair and nails.
Dermatophyte infection is transmitted by direct skin contact with infected person and by sharing objects of daily use (fomites).
The folds of the body are the most common sites affected, especially the groins (hence termed jock itch), the armpits, areas below the breasts. The infection can extend onto the abdomen, buttocks and thighs.
The palms, soles, web spaces of fingers and toes may present with itchy and scaly lesions.
Nails may be infected and act as a source for recurrent Dermatophytosis. The nails may show discoloration or total damage of the nail plate can be seen. Toe nail infections are common in elderly and diabetic patients.
Hair infection and appears as scaly patches with loss of hair or severe infections with pus filled lesions may be seen. Hair involvement is common in children.
Consult a dermatologist since it can be easily diagnosed by the presence of itching clinical appearance of the lesions.
Diagnosis is usually done by dermatologist based on clinical features. If needed, scrapings from the skin or clippings of the nail and hair can be subjected to laboratory tests to confirm the diagnosis and identify the causative fungus by microscopy and culture.
Various topical and systemic antifungals are available for treatment.
Topical antifungal agents include terbinafine clotrimazole, miconazole, eberconazole, luliconazole, ketoconazole etc.
Oral antifungals include agents such as fluconazole, itraconazole, terbinafine and griseofulvin. Oral antihistaminics such as cetirizine, levocetirizine are also prescribed to reduce the itching.
Dose, duration and type of medicine is decided by the dermatologist based on severity of the disease, and presence of other diseases such as kidney/liver disease, pregnancy as it can alter the choice of medicine.
These creams when applied may temporarily make you feel better with the relief of symptoms, because of the steroid component, but the fungal infection never clears out and over a period of time there are steroid related side effects on the skin like thinning, stretch marks and light coloured patches. Hence it is important that creams for ringworm should not be purchased over the counter without a valid prescription or on the recommendation of friends/neighbours/family members/non allopathic-non dermatology professionals.
Use of oral antifungals can have adverse effects on liver and it can also have certain interaction with medication for diabetes. Hence inform your dermatologist about the medicines you are taking before he prescribes you any medicines. The dermatologists may also order some blood tests before prescribing and while you are on those medicines.
