Onychomycosis– is a condition that we refer to as a fungal infection of the nail plate. It is the most common infection of the nail plate. About 8% of the adult population suffer from fungal infections of nail plates. The nail plates often present as yellow, thick, flacky, and misshapened and my also become lifted from the underlying nail bed. In severe cases, there also may be an odor to the nail plate.
There are four different types of categories of onychomycosis.
1. Candidal Onychomycosis occurs when Candida (yeast) infects that nail plate.
2. Superficial White Onychomycosis (SWO) occurs when fungus infects the top layers of the nail plate. One will see white islands of infection along the nail plate.
3. Proximal Subungual Onychomycosis (PSO) occurs when the nail plate along the cuticle becomes infected with fungus. This type of onychomycosis occures more commonly in immunocompromised individuals.
4. Distal Subungual Onychomycosis (DSO) is the most common cause of onychomycosis. The nail infection will begin along the tip of the nail plate and work its way back towards the base of the nail plate.
Onychomycosis can be caused by dermatophytes, Candida, and non dermatophytic molds. The most common dermatophytes Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum. Candida infections are more often aquired in people that work with water. Onychomycosis caused by molds is often seen in more tropical parts of the world.
Factors that place an individual at risk are occlusive footware, age, medical conditions such as diabetes and poor circulation, immunosuppression (HIV), trauma and warm climates.
North Dallas Ingrown Toenail Specialists recommend nail plate samples to be sent to histology lab for confirmation of onychomycosis. This is done by taking a sample of the infected nail plate and sending it to a dermatopathologist for examination.
Treatment of an onychomycotic nail plate can be a long process since the infection is within the nail plate. Current treatment options include topical medications such as Penlac which is a prescription topical nail lacquer and non-prescription, Formula 3 that is available at North Dallas Ingrown Toenail Specialists.
Oral medications include Lamisil which is the most effective oral antifungal. Prior to being placed on this medication, it is highly advised that you have a blood test to check your liver enzyme levels (AST and ALT) to confirm that you are healthy enough to take the medication.
