WHAT'S
THE PROBLEM?
Fungus Nails is an unsightly infection of the nails,
causing thickened, brittle, yellow, discolored and sometimes
painful nails. It is very difficult to cure. It is caused by
one of several microscopic organisms, similar to those that cause
Athlete's Foot (dermatophytosis) These are plant like organisms
that thrive in a dark, warm, moist environment, such as within
shoes and stockings. They grow in the nail bed, beneath your
nails, and live off Keratin, the protein in the nail. The condition
usually begins toward the far end of the nail and may cause white
or yellow-white areas that appear to be rotten or dead. If the
infection continues to the base of the nail, it can invade the
nail root (matrix) and cause the nail to grow thickened and deformed.
Many people complain of a foul odor associated with this condition.
It can also spread to other nails. The fungus often spreads to
the adjacent skin surrounding the nail.

HOW DOES IT FEEL?
It may not be painful in the beginning, and may
only look slightly different than the normal nails. Later, the
nail may begin to show small patches of white or yellowish-tan
color and may become brittle and split. As it progresses, the
nail becomes thicker and deformed and may begin to grow at an
angle and become an Ingrown Nail. Pain develops, due to the ingrown
or thickened nail deformity, and becomes aggravated by pressure
applied by shoes. Inflammation can develop due to this pressure
and a secondary bacterial infection may occur, leading to more
pain. Even without inflammation, shoe pressure on the fungal
nails can cause pain, making it difficult to walk or stand
for periods of time. This can also influence one's involvement in day to day
activities.
LET'S DO A TEST!
Correct evaluation and diagnosis is important, as other common
medical conditions, such as psoriasis, can look like Fungus Nails. Your doctor
may make this decision by examination alone. He may also examine scrapings
from the nail under the microscope or send these scrapings to the lab for accurate
identification, to determine if the condition is a fungus and what type of
fungus is responsible.
HOW DID THIS HAPPEN?
Many types of fungus are common in our environment. Among them
are the dermatophytes, a group of opportunistic parasitic plant organisms,
similar to molds or mildew, that, lacking chlorophyll, do not require sunlight
for growth. Sweaty tennis shoes and moist socks create the perfect conditions
for them. The funguses thrive in a warm, moist, dark environment and they eat
the protein keratin that our skin produces. Although funguses may be present
in the skin around the nails, one may not develop a nail infection without
history of injury, such as bruised nails from short shoes, inflammation from
an ingrown nail, or from cutting the nails incorrectly or too short. In other
words, the organisms do not invade intact, healthy, normal skin or nails. Other
contributing factors would be excessive perspiration, and Dermatophytosis (Athlete's
Foot), which is caused by similar fungi. Some individuals appear to be more
susceptible to infection. These would include those with medical conditions
such as diabetes and poor circulation and HIV. For that reason, even if treatment
is successful in eliminating the condition, the susceptible person may become
re-infected in the future.
WHAT CAN I DO FOR IT?
Topical medications are ineffective in most cases, because the
infection starts growing under the nail. No topical medicines penetrate deep
enough into and through the nail, to treat the living organisms under the nail
plate. Any clearing of the nail surface is eventually overtaken by infected
nail replacing it from underneath. Unfortunately, in this condition, any self
treatment is, at best, temporary. Use of a topical antifungal medicine may,
at best, prevent spread of the fungus to, as yet, unaffected nails or the surrounding
skin.
WHAT WILL MY DOCTOR DO FOR IT?
First of all, the doctor will do a physical examination to determine
if there is a fungus present and not some other kind of medical condition.
After determining the type of fungus, treatment may range from topical solutions
to oral, systemic medications. The nails may be trimmed and reduced with an
electric grinder periodically, and you may be asked to participate in some
way at home. Surgical and/or laser treatment may address removal of part or
all of the nail with additional medications to prevent recurrence as the new
nail grows.
Fortunately, oral medications are now available that have proven very effective
in curing these difficult infections. These medicines reach the nail through
the blood stream and create a barrier between the old infected nail, and the
newly formed nail, effectively killing all living fungus organisms.. The medications
are taken for about three months. During that time, they penetrate into and
saturate the growing part of the nail. Even after you stop taking the medicine,
the medicine that has gotten into the nail continues to treat the nail from
inside for another six to nine months, until a healthy nail has completely
grown out. The medicines seem expensive initially, but in the long run, they
are more economical than previous long term treatments, and they offer a good
chance of a cure. Although these medications are safe, there are some side
effects in a small percentage of patients and they require a blood test to
monitor blood levels. Your doctor will discuss the advantages and disadvantages
of oral therapy and other alternatives with you, to determine the most appropriate
treatment in your situation.
CAN I PREVENT FROM IT HAPPENING AGAIN?
You may be asked to treat the insides of your shoes, which have become
contaminated by the fungus. This is to make sure that the new healthy nail
doesn't become contaminated by any fungus hiding in the shoe.
To prevent the fungus infection from coming back, the best offense is a good
defense. We must control moisture and create a drier environment for your feet.
Use powder in shoes, to absorb perspiration. Avoid synthetic or nylon socks
that trap, rather than absorb perspiration. Cotton socks absorb moisture and
wick it away from the skin and nails. Keeping your feet dry and protected from
injury is essential to avoid any fungus infections. If you have been cutting
your nails too deeply, or treating an ingrown nail on your own, this may have
allowed the fungus to grow under the nail. If shoes have become contaminated
while you had the condition, they may be sanitized by spraying them with a
topical antifungal spray, to prevent a recurrence of the Fungal Nail condition.
