Fungal Infections of the nail
It is the most common disease of the nails and constitutes about a half of all nail abnormalities.This condition may affect toenails or fingernails, but toenail infections are particularly common. The prevalence of onychomycosis is about 6-8% in the adult population.
The nail plate can have a thickened, yellow, or cloudy appearance. The nails can become rough and crumbly, or can separate from the nail bed. There is usually no pain or other bodily symptoms, unless the disease is severe.
There are four classic types of onychomycosis:
Treatment of onychomycosis is challenging because the infection is embedded within the nail and is difficult to reach. As a result, full removal of symptoms is very slow and may take a year or more.
Most treatments are either systemic antifungal medications, such as terbinafine and itraconazole, or topical, such as nail paints containing ciclopirox or amorolfine.
There is also evidence for combining systemic and topical treatments.
Alternative medicines:
As with many diseases, there are also some scientifically unverified folk or alternative medicine remedies.
Australian tea tree oil has been tested, but there is insufficient information to make recommendations for its use for onychomycosis.
If you feel you have a fungal infection in your toe/s, please feel free to contact me to arrange an appointment to discuss potential treatments.

The nail plate can have a thickened, yellow, or cloudy appearance. The nails can become rough and crumbly, or can separate from the nail bed. There is usually no pain or other bodily symptoms, unless the disease is severe.
There are four classic types of onychomycosis:
- Distal subungual onychomycosis is the most common form of tinea unguium, and is usually caused by Trichophyton rubrum, which invades the nail bed and the underside of the nail plate.
- White superficial onychomycosis (WSO) is caused by fungal invasion of the superficial layers of the nail plate to form "white islands" on the plate. It accounts for only 10 percent of onychomycosis cases. In some cases, WSO is a misdiagnosis of "keratin granulations" which are not a fungus, but a reaction to nail polish that can cause the nails to have a chalky white appearance. A laboratory test should be performed to confirm.
- Proximal subungual onychomycosis is fungal penetration of the newly formed nail plate through the proximal nail fold. It is the least common form of tinea unguium in healthy people, but is found more commonly when the patient is immunocompromised.
- Candidal onychomycosis is Candida species invasion of the fingernails, usually occurring in persons who frequently immerse their hands in water. This normally requires the prior damage of the nail by infection or trauma.

- Grapefruit seed extract as a natural antimicrobial is not demonstrated. Its effectiveness is scientifically unverified. Multiple studies indicate the universal antimicrobial activity is due to contamination with synthetic preservatives that were unlikely to be made from the seeds of the grapefruit.
- Snakeroot leaf extract has, in studies, shown ability to treat superficial onychomycosis, although the results show it is less effective, and equal to conventional drugs ciclopirox and ketaconazole, respectively.
