Onychomycosis

Definition:
Onychomycosis (also known as “dermatophytic onychomycosis,” “ringworm of the nail,” and “tinea unguium”) means fungal infection 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.

Clasification:
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.

Symptoms:
The nail plate can have a thickened, yellow-brown , or cloudy appearance. The nails can become rough and crumbly  , or can separate from the nail bed. This thickening, discolouration and disfigurement are clearly visible.There is usually no pain or other bodily symptoms, unless the disease is severe.

Dermatophytids are fungus-free skin lesions that sometimes form as a result of a fungus infection in another part of the body. This could take the form of a rash or itch in an area of the body that is not infected with the fungus. Dermatophytids can be thought of as an allergic reaction to the fungus. People with onychomycosis may experience significant psychosocial problems due to the appearance of the nail. This is particularly increased when fingernails are affected.

The effects of onychomycosis aren’t simply cosmetic. A thickened nail may limit usual activities. It may press on the inside of footwear, for example, causing discomfort and pain. This in turn can cause problems when walking, and reduce mobility.

Causes:
Onychomycosis is caused by 3 main classes of organisms: dermatophytes (fungi that infect hair, skin, and nails and feed on nail tissue), yeasts, and nondermatophyte molds. All 3 classes cause the same symptoms, so the appearance of the infection does not reveal which class is responsible for the infection. Dermatophytes (including Epidermophyton, Microsporum, and Trichophyton species) are, by far, the most common causes of onychomycosis worldwide. Yeasts cause 8% of cases, and nondermatophyte molds cause 2% of onychomycosis cases.

•The dermatophyte Trichophyton rubrum is the most common fungus causing distal lateral subungual onychomycosis (DLSO) and proximal subungual onychomycosis (PSO).

•The dermatophyte Trichophyton mentagrophytes commonly causes white superficial onychomycosis (WSO), and more rarely, WSO can be caused by species of nondermatophyte molds.

•The yeast Candida albicans is the most common cause of chronic mucocutaneous candidiasis (disease of mucous membrane and regular skin) of the nail.

Risk Factors:
Risk factors for onychomycosis include family history, advancing age, poor health, trauma, living in a warm climate, participation in fitness activities, immunosuppression (can occur from HIV or certain drugs), bathing in communal showers (such as at a gym), and wearing shoes that cover the toes completely and don’t let in any airflow.

People with diabetes are at greater risk, as are those whose immune system is suppressed.

It’s possible to reduce your risk of onychomycosis by practising good nail care. This reduces the risk of other nail and foot-related problems, too.

Diagnosis:
Onychomycosis (OM) can be identified by its appearance. However, other conditions and infections can cause problems in the nails that look like onychomycosis. OM must be confirmed by laboratory tests before beginning treatment, because treatment is long, expensive, and does have some risks.

•A sample of the nail can be examined under a microscope to detect fungi. See Anatomy of the Nail for information on the parts of the nail.

•The nails must be clipped and cleaned with an alcohol swab to remove bacteria and dirt.

•If the doctor suspects distal lateral subungual onychomycosis (DLSO), a sample (specimen) should be taken from the nail bed to be examined. The sample should be taken from a site closest to the cuticle, where the concentration of fungi is the greatest.

•If proximal subungual onychomycosis (PSO) is suspected, the sample is taken from the underlying nail bed close to the lunula.

•A piece of the nail surface is taken for examination if white superficial onychomycosis (WSO) is suspected.

•To detect candidal onychomycosis, the doctor should take a sample from the affected nail bed edges closest to the cuticle and sides of the nail.

•In the laboratory, the sample may be treated with a solution made from 20% potassium hydroxide (KOH) in dimethyl sulfoxide (DMSO) to rule out the presence of fungi. The specimen may also be treated with dyes (a process called staining) to make it easier to see the fungi through the microscope.

•If fungi are present in the infected nail, they can be seen through a microscope, but the exact type (species) cannot be determined by simply looking through a microscope. To identify what exactly is causing onychomycosis, a technique called culturing is used. Using a fungal culture to identify the particular fungus is important because regular therapy may not work on nondermatophyte molds.

…#The infected nail is scraped or clipped.

…#The scrapings or clippings are crushed and put into containers. Any fungus in the samples can grow in the laboratory in these special containers.

…#The species of fungus can be identified from the cultures grown in the lab.

Treatment:
Medications
In the past, medicines used to treat onychomycosis (OM) were not very effective. OM is difficult to treat because nails grow slowly and receive very little blood supply. However, recent advances in treatment options, including oral (taken by mouth) and topical (applied on the skin or nail surface) medications, have been made. Newer oral medicines have revolutionized treatment of onychomycosis. However, the rate of recurrence is high, even with newer medicines. Treatment is expensive, has certain risks, and recurrence is possible.

•Topical antifungals are medicines applied to the skin and nail area that kill fungus.

…#These topical agents should only be used if less than half the nail is involved or if the person with onychomycosis cannot take the oral medicines. Medicines include amorolfine (approved for use outside the United States), ciclopirox olamine (Penlac, which is applied like nail polish), sodium pyrithione, bifonazole/urea (available outside the United States), propylene glycol-urea-lactic acid, imidazoles, such as ketoconazole (Nizoral Cream), and allylamines, such as terbinafine (Lamisil Cream).

…#Topical treatments are limited because they cannot penetrate the nail deeply enough, so they are generally unable to cure onychomycosis. Topical medicines may be useful as additional therapy in combination with oral medicines.

•Newer oral medicines are available. These antifungal medicines are more effective because they go through the body to penetrate the nail plate within days of starting therapy.

…#Newer oral antifungal drugs terbinafine (Lamisil Tablets) and itraconazole (Sporanox Capsules) have replaced older therapies, such as griseofulvin, in the treatment of onychomycosis. They offer shorter treatment periods (oral antifungal medications usually are administered over a 3-month period), higher cure rates, and fewer side effects. These medications are fairly safe, with few contraindications (conditions that make taking the medicine inadvisable), but they should not be taken by patients with liver disease or heart failure. Before prescribing one of these medications, doctors often order a blood test to make sure the liver is functioning properly. Common side effects include nausea and stomach pain.

…#Fluconazole (Diflucan) is not approved by the Food and Drug Administration (FDA) for treatment of onychomycosis, but it may be an alternative to itraconazole and terbinafine.

•To decrease the side effects and duration of oral therapy, topical and surgical treatments may be combined with oral antifungal management.
Surgery

Surgical approaches to onychomycosis treatment include surgically or chemically removing the nail (nail avulsion or matrixectomy).

•Removing the nail plate (fingernail or toenail) is not effective treatment on its own. This procedure should be considered an adjunctive (additional) treatment combined with oral therapy.

•A combination of oral, topical, and surgical therapy can increase the effectiveness of treatment and reduce the cost of ongoing treatments.

Research:
Most drug development activities are focused on the discovery of new antifungals and novel delivery methods to promote access of existing antifungal drugs into the infected nail plate. Active clinical trials investigating onychomycosis:

Phase III
*A topical treatment, AN2690, is being developed by Anacor Pharmaceuticals.  It is active against Trichophyton species.

*A medicinal nail lacquer, MycoVa from Apricus Biosciences,[40] contains terbinafine as the active ingredient and a permeation enhancer DDAIP which facilitates the delivery of the drug into the nail bed where the fungus resides.

*A comparison of delivery methods for itraconzole

*Safety and tolerability of topical terbinafine

*Laser-based treatments

*Topical IDP-108

*Bifonazole cream application after nail ablation with urea paste

Phase II
*Posaconazole, taken orally.

*A topical treatment, NB-002, is being developed by NanoBio Corporation. It has completed Phase II trials

Onycholysis

[amazon_link asins=’B00AVP37G8,B015RR4I3A,B00KLE0Y7O,B004I94DF2,B00GHODSES,B0083EP6OU’

Definition:
Onycholysis is a diseases whose symptoms appear as the separation of the nail plate from the nail bed on your fingers and toes. But that is not the full definition. The separation must be gradual and must be painless. Onycholysis can happen due to a number of reasons including trauma, onychomycosis or fungal infection in the nails. Onycholysis is generally seen in adulthood and might be symptomatic of other skin diseases or infections, allergic contact to some compounds like acrylic nail products, consequence of an injury, or hyperactive thyroid glands.

Onycholysis disease is not restricted to any one sex but generally women are more prone to it specially those who keep long fingernails. Actually long fingernails result in its tip being hit against hard objects repeatedly. It is also seen that the affected nails don’t show any skin inflammation and the finger nail remains firm and smooth. It is simply because onycholysis is not a disease of the nails tissue matrix.

Symptoms:
It is actually very easy to spot Onycholysis nail disease. You’ll find that the nail lifts itself from its bed and there is a gap between the pink portion of the nail and the white outside edge of the finger nail.
Click to see the picture
One way of determining Onycholysis has set in to check for signs of discoloration underneath the nail since this may occur as a result of secondary infection. The painless and spontaneous separation of the nail plate starts at the distal free margin and gradually progresses proximally. That actually signifies secondary infection making the situation more serious. Secondary infections might also result in the deformation of the shape of the nail plate and appearance of pits and indentations in the nail surface.
Larger portion of the nail may become opaque, get whitened or discolored to yellow or green and this calls for medical attention.

Causes:
*Idiopathic
*Trauma e.g. excessive manicuring
*Infection: especially fungal
*Skin disease: psoriasis, dermatitis
*Impaired peripheral circulation e.g. Raynaud’s
*Systemic disease: hyper- and hypothyroidism, reactive arthritis

Diagnosis:
Diagnosing Onycholysis is simple and straight forward. To diagnose Onycholysis you must examine closely your fingernails and the toenails for nail plate separation, opacity and discoloration and effects the disease might have on the peripheral skin surrounding your nails and toes. If you feel that something is wrong but can’t make a clear diagnostic, you need to go see your doctor or physician who would look for and diagnose for other symptoms and search for other symptomatic signs of the disease such as skin appearance around your nails or the appearance of indentations in the surface or the color and shape of the nails. Doctors search for sign of rashes on the skin or even check for related symptoms linked to thyroid problems. If the diagnostic suspicious of your doctor leans towards fungal infection, some tissues from beneath your nail plate might be scraped out for further testing.

Treatment:

Treatment usually involves tackling the underlying cause, such as a fungal infection.

Nail changes aren’t usually permanent, but they can take many months to resolve, even after treatment.
*Some of the remedial measures one can take for Onycholysis at home include regular trimming of nails to ensure they remain short and clean (manageable too) and using a skin softening hand cream to nourish the nails and hands.
*If Onycholysis has set in due to nail biting, picking or tearing, the person can consider seeking psychological counseling to get the necessary encouragement and guidance to underlying problems to stop this behavior.
*Persons suffering from Onycholysis should wear light cotton gloves under vinyl gloves for wet work and avoid keeping their hands immersed for prolonged periods in water.


*If Onycholysis has set in on the feet, one should avoid wearing tight shoes and trim the nails straight across the top only.

Prevention:
What you can do is to take some preventive steps to avoid the occurrence of onycholysis. You can start with avoiding exposure to harsh chemicals like nail polish remover. You would do well to wear cotton gloves or rubber gloves while immersing your nails in water repeatedly. Nails expand when it is moisten and shrinks when it dries. And yes, clip your nails at the affected portion and try to keep your nails short to avoid further trauma from getting damaged everyday.

Nail Diseases & Disorders

Definition:
Nail diseases & disorders are distinct from diseases of the skin. Although nails are a skin appendage, they have their own signs and symptoms which may relate to other medical conditions. Nail conditions that show signs of infection or inflammation require medical assistance and cannot be treated at a beauty parlor. Deformity or disease of the nails may be referred to as onychosis.

A nail disorder is a condition caused by injury to the nail or disease or imbalance in the body.Many persons have had some type of common nail disorder at some part of their lifetime. In some cases one can cosmetically improve a nail disorder but to get a permanent result it is always wise to contact a Licensed Nail Technician.

There are many different kinds of nail diseases and disorders and some of them are mentioned below:-

Click to see the pictures

Bruised Nails
is a condition in which a clot of blood forms under the nail plate. The clot is caused by injury to the nail bed. It can vary in color from maroon to black. In some cases, a bruised nail will fall off during the healing process. Severe bruising should not be worked on.

Onychatrophia
Also known as atrophy describes the wasting away of the nail. The nail loses its shine, shrinks, and falls.
This can be caused by injury to the nail matrix or by internal disease.
Handle this condition with care

——————————————————————————–

Onychauxis
Show the opposite symptoms of onychatrophia.
Nails with this disorder are abnormally thick. The condition is usually caused by internal imbalance, local infection, or heredity.
File the nail until smooth and buff

——————————————————————————–

Onychocryptosis:

Onychocryptosis, commonly known as “ingrown nails” (unguis incarnatus), can affect either the fingers or the toes. In this condition, the nail cuts into one or both sides of the nail bed, resulting in inflammation and possibly infection.Ingrown nails is a familiar condition of the fingers and toes in which the nail grows into the sides of the tissue around the nail.If the nail is not too deeply imbedded in the flesh, you can trim the corner of the nail in a curved shape to relieve the pressure on nail groove. If it is deep they should see a doctor.

The relative rarity of this condition in the fingers suggests that pressure from the ground or shoe against the toe is a prime factor. The movements involved in walking or other physical disturbances can contribute to the problem. Mild onychocryptosis, particularly in the absence of infection, can be treated by trimming and rounding the nail. More advanced cases, which usually include infection, are treated by surgically excising the ingrowing portion of the nail down to its bony origin and thermally or chemically cauterizing the matrix, or ‘root’, to prevent recurrence. This surgery is called matrixectomy. The best results are achieved by cauterizing the matrix with phenol. Another, much less effective, treatment is excision of the matrix, sometimes called a ‘cold steel procedure’.

——————————————————————————–

Onychophagy
Is the medical term for nails that have been bitten enough to become deformed. This condition can be greatly improved by regular manicures or artificial nails.
It is not realistic to tell a nail biter to come back for artificial nails after they have grown a free edge. Artificial nails can help this person break the biting habit. There are also nail biting topically applied remedies available.

——————————————————————————–

Pterygium nail
Describes the common condition of the forward growth of the cuticle on the nail. The cuticle sticks to the nail plate and, if not treated, will grow over the nail to the free edge.

The nail pictured is an extreme case and will take several manicures to get the cuticle back in place.

——————————————————————————–

Leukonychia
Is a condition in which white spots appear on the nails. It is caused by air bubbles, a bruise or other injury to the nail.
Leukonchia can not be corrected but it will grow out.

——————————————————————————–

Onychorrhexis
Refers to split or brittle nails that also have a series of lengthwise ridges. It can be caused by chemicals, injury to the fingers, excessive use of cuticle solvents, nail polish removers and careless rough filing.
This condition may be corrected by softening the nails with a reconditioning treatment and discontinuing the abuse.

——————————————————————————–

Hangnails
Is a common condition in which the cuticle around the nail splits.
Hangnails are caused by dry cuticles and skin. They are also aggravated by improper trimming.
This disorder can be solved by keeping the cuticles moisturized with oil and lotion. These can become infected and very painful

——————————————————————————–

Furrows
Also known as corrugations, are long ridges that run either lengthwise or across the nail. Some lengthwise ridges are normal in adults.
These ridges increase with age and can also be caused by psoriasis, poor circulation and frostbite.
Ridges that run across the nail are caused by high fevers, pregnancy & measles

——————————————————————————–

Eggshell Nails
Are thin, white, and curved over the free edge. The condition is caused by improper diet, internal disease, medication, or nervous disorders. Be careful when manicuring these nails because they are fragile and break easily.

——————————————————————————–

Discolored Nails..
This is a condition in which the nails turn a variety including yellow, blue, blue-gray, green, red and purple. Discoloration can be caused by poor circulation, a heart condition, or topical or oral medications. It may also indicate the presence of a systemic disorder. Artificial wraps, tips or an application of colored polish can hide this condition.
