What causes Erythronychia?
Longitudinal erythronychia is thought to arise due to matrix function loss and longitudinal thinning of the ventral plate [2, 11]. The thinning of the nail plate creates a longitudinal groove into which the neighboring nail bed swells, resulting in a vascular congestion that manifests as erythema.
Can trauma cause Beaus lines?
Trauma or damage to your nail matrix can cause Beau’s lines, such as: Dropping something heavy on your finger or toe. Exposure to extreme cold. Manicure or artificial nails.
Can paronychia be caused by trauma?
Paronychia is nail inflammation that may result from trauma, irritation or infection. It can affect fingernails or toenails. Paronychia can develop when bacteria enter broken skin near the cuticle and nail fold, causing an infection.
Does stress cause paronychia?
Causes of paronychia The infection is often introduced by injury, or by stress. It occurs three times as frequently in women as in men. Fungal paronychia is more common in those who are diabetic, as well as those who wash their hands a lot.
What causes longitudinal erythronychia?
The most common causes of longitudinal erythronychia involving multiple nails are lichen planus and Darier disease. Less common etiologies are systemic amyloidosis, hemiplegia, graft-versus-host disease, and acantholytic epidermolysis bullosa.
How is longitudinal erythronychia treated?
Treatment of longitudinal erythronychia depends on the etiology. For patients with longitudinal erythronychia-associated discomfort or severe nail splitting, a surgical excision may provide not only the underlying diagnosis of the nail dyschromia, but also relief of related symptoms.
Can Beaus lines be benign?
Beau’s lines are fairly common nail changes in patients on chemotherapy. Beau’s lines harbingers variety of medical disorders (benign and malignant).
Can Beau’s lines be harmless?
Beau’s lines are horizontal, going across the nailline, and should not be confused with vertical ridges going from the bottom (cuticle) of the nail out to the fingertip. These vertical lines are usually a natural consequence of aging and are harmless.
Who is most likely to develop paronychia?
People who have a habit of picking at the skin around the nail, or babies who suck thumbs and break the tender skin around the nail are quite likely to develop chronic paronychia. People who have diabetes are more prone to skin infections in general and tend to get paronychia frequently.
Is longitudinal Erythronychia treatment?
What is longitudinal Erythronychia?
Background Longitudinal erythronychia (LE) is a term for red streaks in the nail. We describe the range of diseases manifested by localized (single or bifid) LE and explain the underlying physical changes. Observations Longitudinal erythronychia can be multiple or localized.
Should I worry about Beau lines?
Deep horizontal ridges, called Beau’s lines, are often symptoms of a serious condition, according to 2018 research . They may actually stop nail growth until the underlying condition is treated. Acute kidney disease may also be present if Beau’s lines appear.
Do Beau lines disappear?
As the nail grows, the Beau’s lines can disappear. Beau’s lines can be caused by trauma or local disease involving the nail fold. They can vary based upon the width or depth of the depression, reflecting the duration or extent of the damage.
Are Beau’s lines permanent?
Why do I keep getting paronychia?
Paronychia (pair-oh-NIE-kee-ah) is a common problem that affects fingernails and toenails. It is caused by an infection of the skin around the nail. Chronic paronychia can happen after dish washing, finger sucking, trimming the cuticles too much, or frequent contact with chemicals.
What is erythronychia?
Erythronychia is a term that covers a range of pathological patterns of red discoloration of the subungual tissues. The intensity of the red contrasts with the pale pink of the nail bed or the cream color of the lunula.
Longitudinal erythronychia may be specific to one nail or involve multiple nails. When longitudinal erythronychia involves one nail, it may be caused by benign conditions, such as onychopapilloma, wart, warty dyskeratoma, glomus tumor, or a solitary lesion of lichen planus.
What causes erythronychia on one nail?
Synopsis. When longitudinal erythronychia involves one nail, it may be caused by benign conditions, such as onychopapilloma, wart, warty dyskeratoma, glomus tumor, or a solitary lesion of lichen planus. Less commonly, it may be caused by malignancies, such as Bowen disease, invasive squamous cell cancer, melanoma in situ, and basal cell carcinoma.
What is the shear stress of erythrocytes under shear conditions?
Studies have been performed on erythrocytes that have been subjected to a low shear stress of less than 100 dyn/cm2in a cone-and-plate viscometer.
