BACKGROUND Nail apparatus melanoma is known to be associated with a poor prognosis, mainly because of a delay in diagnosis that is made at an invasive stage. This delay is particularly true in cases involving amelanotic melanoma. To our knowledge, only 1 case of in situ amelanotic melanoma of the nail unit has previously been described. We report 3 cases of in situ amelanotic melanoma with clin...

Nail is a tool that greatly reduces the programmer effort for safely parsing and generating data formats defined by a grammar. Nail introduces several key ideas to achieve its goal. First, Nail uses the protocol grammar to define not just the data format, but also the internal object model of the data. Second, Nail eliminates the notion of semantic actions, used by existing parser generators, w...

BACKGROUND Vitiligo is an acquired pigmentary skin disorder affecting 0.1-4% of the general population. The nails may be affected in patients with an autoimmune disease such as psoriasis, and in those with alopecia areata. It has been suggested that nail abnormalities should be apparent in vitiligo patients. OBJECTIVE We sought to document the frequency and clinical presentation of nail abnor...

Background Onychomycosis is a fungal infection causing progressive destruction of the nail elements, with age increasing frequency of infection and potential for complications. The condition accounts for almost half of all nail issues yet continues to be largely under-reported and untreated. This study will investigate the antifungal efficacy of eucalyptus oil in vivo, for fungal nail infection...

Of 135 consecutive patients admitted with subtrochanteric fractures of the femur, 104 were studied; half had internal fixation with a Zickel nail and half had a nail-plate device. Fractures treated with a Zickel nail had significantly less blood loss during operation and took less time to walk with full weight-bearing, but the incidence of technical error at operation was higher. Errors include...

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...
