Help Notes for Nurses No. 1 -- Infections and Deformities of Toenails
What is Onychomycosis?
• Onychomycosis is an infection of toenails or fingernails associated with fungi or molds.
Why does Onychomycosis need nurses' attention?
• Onychomycosis may lead to big medical problems as well as reduce a person's quality of life. Its fungal lesions may spread to other places in the body including the scalp and skin. Some of these legions are contagious.
• "Onychomycosis is the most common nail disorder in adults. It is four to seven times more frequent in toenails, where it often involves several nails. It is a progressive disease
• In the "Foot-Check-Study within the European Achilles project, it's prevalence rate in Germany was found to be 12.4%.
What are its core features?
• Onychomycosis is a progressive disease most likely to be found among adults, and often involves several toenails.
• Often the nail plate is discolored, and as the the the disease progresses it might be lost altogether as the nail plate becomes detached from the nail bed.
To what deeper disease conditions might Onychomycosis point?
• Onychomycosis is a predictor for development of diabetic foot syndrome and foot ulcer.
What are some its predisposing factors?
• Diabetes mellitus is one of its disposing factors.
What are the available treatment strategies?
• Treatment strategy is mostly involve oral and topical therapies, with the former tending to be more effective. New drugs are being developed and some are are undergoing clinical trials. A key problem is the difficulty of nail permeation by drugs.
• Thus attentive caring for skin and nail disorders is important to inhibit problems developing in deeper structures of the foot.
• The most common topical application is ciclopirox (8% nail lacquer). This has limited effectiveness; yet the development of more in effective applications has proven to be a challenge.
