Two common infections that cause nail dystrophy are onychomycosis and psoriasis

Although not life-threatening, onychomycosis (a fungal infection of the nail, usually caused by a dermatophyte) constitutes an important public health problem because of its high prevalence (about 10 of the U. The differential diagnosis includes psoriasis, lichen planus, onychogryphosis, and nail trauma. Fungal Nail Infections are caused by keratin becoming infected with fungi. The most common result is a poor cosmetic appearance of the affected nail(s); Diabetes mellitus – one study found that clinical onychomycosis was found in 162 of 321 patients with type 2 diabetes mellitus. Causes chronic paronychia with secondary nail dystrophy. A common problem resulting from various causes – eg, improperly trimmed nails, hyperhidrosis and poorly fitting shoes. In psoriasis can see a yellowish-brown margin between the margin between the normal nail (pink) and the detached parts (white). Median nail dystrophy. Cause of 2-3 of melanomas in white patients and 1 in 5 or 6 black patients. Fungal nail infections – onychomycosis.

Two common infections that cause nail dystrophy are onychomycosis and psoriasis 2Candida spp. mainly cause fingernail onychomycosis in people whose hands are often submerged in water. To avoid misdiagnosis as nail psoriasis, lichen planus, contact dermatitis, nail bed tumors such as melanoma, trauma, or yellow nail syndrome, laboratory confirmation may be necessary. Onychomycosis is a fungal infection of the nails that causes discoloration, thickening, and separation from the nail bed. 8 times higher in persons with diabetes compared with the general population.2 In patients with human immunodeficiency virus infection, the prevalence ranges from 15 to 40. Another cause of nail dystrophy; mixed disease (e.g., onychomycosis and psoriasis). Caused by either exogenous or endogenous factors, nail dystrophy Classically, psoriatic nail disease consists of: onycholysis; salmon (oil) spots (discolored areas that represent nail bed psoriasis); an irregular pitting pattern; and onychauxis. Biotin, an oral option for brittle nails, benefits dystrophic nails approximately two to three months after patients start using the supplement.

2. Identify the most common nail disorders, including etiology and treatment. Psoriasis causes thickened nails because of abnormal retained hard keratin; other characteristics include pits and small irregular depressions in the nails, distal onycholysis (abnormal thick and separated distal nail plate), and whole-nail dystrophy similar to tinea. Distal and lateral subungual onychomycosis is the most common infection affecting the distal portion of the nail. It should be distinguished from other causes of onychomycosis:. It is often confused with non-infected nail dystrophy due to skin disease, particularly psoriasis (also dermatitis, lichen planus, viral warts, ageing changes). Lateral onychomycosis Superficial white onychomycosis Total nail destruction Onychomycosis Onychomycosis may look similar to nail dystrophy due to trauma, psoriasis, lichen planus, aging changes and even melanoma. Fungal infection is quite common in damaged nails, so antifungal therapy does not always return the nail to normal even when culture is positive. Fungal nail infections, also called onychomycosis, are among the most common nail disorders. The most common feature is affliction of the lateral edges or sides of the nail bed initially. The third type of infection is Total nail dystrophy that leads to thickening of the entire nail. The nail anatomy under the microscope helps determine other causes of nail discoloration and deformity like psoriasis.


Onychomycosis is by far the most common nail dystrophy we see in clinical practice. This is a welcome addition to the nail treatment armamentarium.2. When dealing with a dystrophic nail caused by a dermatophyte infection, a fungal culture, PAS stain and/or KOH should be performed before starting therapy to concur with the clinical diagnosis. Psoriasis is a common, chronic, inflammatory disease that has skin, nail, and systemic manifestations. EPIDEMIOLOGY Nail psoriasis occurs in both adults and children 1,2. Testing for fungal infection is often necessary to rule out onychomycosis as an alternative cause of nail dystrophy. Understanding Onychomycosis Treatment: Mechanisms of Action and Formulation. In fact, this condition has been reported in pediatric patients of all ages, including neonates, and always must be considered in the differential in any patient who presents with nail dystrophy. 2. In general, children who present with onychomycosis have a family history of onychomycosis and/or tinea pedis. Geriatric Patients An estimated 40 of elderly patients have onychomycosis, making this one of the most common infections seen in this population. Psoriasis as a comorbid cause for nail symptoms should be considered when mycologic cure is achieved but appearance does not improve completely; the portion of a nail affected by psoriasis will not change with antifungal treatment. Nail fungus and nail psoriasis are the leading causes of dry and brittle nail conditions. Brittle nails, a form of nail dystrophy also known as onychorrhexis, can affect anyone, but the condition is especially common among older women. If you have dry and brittle nails, the protein layers in your nails are prone to separating and breaking off, so the common symptoms of this condition are misshapen or flaky nail plates that may split longitudinally. Onychomycosis (fungal infection) is a very common cause of nail dystrophy. Nail dystrophy occurs in a considerable proportion of patients with psoriasis. Two clinical patterns of nail manifestations have been seen due to psoriasis: nail matrix involvement or nail bed involvement. These clinical features are more visible in fingernails than in toenails, where nail abnormalities are not diagnostic and are usually clinically indistinguishable from other conditions, especially onychomycosis. Nail psoriasis causes, above all, psychosocial and aesthetic problems, but many patients often complain about functional damage. Abstract: Psoriasis is a common skin disease, with nail involvement in approximately 80 of patients.
