Onychomycosis is a type of fungal infection affecting the toenails or
fingernails. It may involve parts of the nail such as the matrix, bed, or
plate. This infection can cause pain, discomfort, and disfigurement and may
produce serious physical and occupational limitations, as well as reducing
quality of life.
This type of infection is found among athletes; it can be caused by immunosuppression,
poor care of the finger and toe especially with people who fix artificial nails,
swim in public pools, and wear tight fitting shoes, etc. onychomycosis of the
toe nails is more common than that of the fingernails.
There are many types of Onychomycosis viz: Distal lateral subungual
onychomycosis (DLSO), White superficial onychomycosis (WSO), proximal subungual
onychomycosis (PSO), Endonyx onychomycosis (EO) and Candidal onychomycosis.
Onychomycosis is caused by three main types of organisms namely;
The dermatophyte, Trichophyton
rubrum – the most common type causing DLSO and PSO (as above)
The dermatophyte, Trichophyton mentagrophytes
– commonly causes WSO, and;
The yeast Candida albicans –
most common cause of chronic mucocutaneous candidiasis (disease of mucous
membrane and regular skin) of the nail.
Signs and
Symptoms:
·
Complaints about the appearance of
the nail, with no physical symptoms
·
With disease progression, there is interference
with standing, walking, and exercising.
·
Paresthesia (a sense of pricking,
tingling, or creeping on the skin having no objective cause and usually
associated with injury or irritation of a nerve), pain, discomfort, and loss of
dexterity are observed.
·
Loss of self-esteem often occur leading
to social problems. Severe candida problems can cause disfiguring of the
fingertips and nails.
PREVENTION
AND TREATMENT
Treatment of onychomycosis is achieved by oral and topical medications.
A combination of both increases the cure rate. However, surgical interventions
may be used as adjunct therapy.
Topical preparations are often useful for prevention of reoccurrence in
people treated with systemic antifungals. These topical preparations include:
·
Ciclopirox olamine 8% nail lacquer
solution
·
Amorolfine or bifonazole/urea
·
Efinaconazole 10% topical solution
(the first topical triazole approved by the FDA for toenail onychomycosis)
·
Tavaborole (Kerydin ®) 5% topical
solution [approved by FDA in 2014] – the first oxaborole antifungal approved
for topical treatment of onychomycosis
Systemic preparations include:
·
Terbinafine
·
Itraconazole
·
Fluconazole and posaconazole
(off-label alternatives)
Non-pharmacological treatment options include:
·
Laser treatment
·
Photodynamic therapy
·
Mechanical, chemical or surgical
nail avulsion
·
Chemical removal with a 40-50% urea
compound in patients with very thick nails
·
Removal of the nail plate in
addition to treatment with oral medications.
PREVENTIVE
MEASURES:
·
Wash your feet and dry them before
putting on your shoes
·
Clip toenails straight across so the
nail doesn’t reach past the tip of the toe – this protects the delicate tissues
beneath the nail
·
Wear properly fitting shoes that
allow space and air into your nail. Avoid wearing damp or wet socks.
·
Use of antifungal sprays on your
shoe
·
Use of shower shoes in public
places, such as damp gym locker rooms and around swimming pools.
·
Maintain good finger and toe nail
hygiene by keeping manicure and pedicure tools clean between uses.
