Manicures can result in nail damage via instrumentation, nail polish, nail polish removers, and artificial nails. We report nail weakness, brittleness, and thinning in five subjects after the application of a new manicure system called gel polish and removal with acetone and manual peeling. All subjects complained that the polish was very difficult to remove and that their nails became much thi...

We hypothesize that nails have an automatic curvature feature and that their flat shape is maintained by the daily upward mechanical forces from the finger/toe pad. Thus, nail deformities, such as pincer nail, spoon nail, and koilonychias, may be caused by an imbalance between these forces and can be treated by controlling these forces. Here, we report the case of a 55-year-old man whose severe...

BACKGROUND Cutaneous T-cell lymphoma can be associated with clinically significant nail alterations, the presentation of which can be protean and misleading. To date, only a few reports have demonstrated direct specific tumor infiltration of the nail bed, while little is known about the efficacy of topical treatments. OBSERVATIONS We describe the case of a 93-year-old man presenting with Séza...

Twenty Nail Dystrophy (TND) is a rare acquired idiopathic nail dystrophy characterized by excess longitudinal ridging, distal notching, splitting, loss of nail luster and thinning of nail plates that may affect 1 to 20 nails. It occurs as a common manifestation of various dermatoses affecting the nail unit like lichen planus, psoriasis, atopic dermatitis, onychomycosis, vitiligo and alopecia ar...

the witkop syndrome is a rare autosomal dominant disorder characterized by the absence of several teeth and abnormalities of the nails. this is the first report of a rare genetic tooth and nail syndrome diagnosed in a 2.5-year-old boy with early exfoliation of the primary canine, absence of the primary incisors, and nail dysplasia. a homozygous mutation was identified in 3’-utr of msx1 gene in ...

BACKGROUND Nail-bed injuries are the most common hand injury in children. Surgical dogma is to replace the nail plate after repairing the nail bed. Recent evidence suggests this might increase infection rates and returns to clinic. The aim of this feasibility trial was to inform the design and conduct of a definitive trial comparing replacing or discarding the nail plate after nail-bed repair. ...

The key objective of this paper is to investigate a new biometric identifier for forensic and civilian applications. We propose a novel biometric authentication system based on low resolution finger nail plate images. Despite the uniqueness and high stability of the nail plate, its usage as a biometric identifier has not been extensively investigated for personal authentication. This paper impl...

Pincer nail deformity is characterized by excessive curvature and distortion of the nail in the transverse dimension, and particularly at the distal part of the nail plate. This deformity leads to pinching off and loss of soft tissue in the affected digit, causing severe pain. Many treatment methods have been proposed; however, an effective long-term method preserving the nail matrix has not ye...

There are different nail manifestations of systemic diseases. This case represents Mees' lines. In the current report, this phenomenon was caused by chemotherapy agents used for treatment of leukemia. It was caused by medication insult to the nail matrix. Nonblanching and impalpable nail bands, migration with the nail growth, and thumb involvement differentiate Mees' from Beau's and Muehrcke's ...

An 8-year old boy with polyarthritis and nail involvement is presented in this report. Nail involvement in Reiter's syndrome is a rare condition that may include painless erythematous nduration of the base of the nail fold; subungual parakeratotic scaling and thickening opacification, ridging of the nail plate.
