SUMMARY Over three successive generations four members of a Sicilian family showed early onset, slowly progressive dystrophy of the finger and toe nails, without any other anomalies or skin signs. Histological examination performed in two patients enabled us to discount lichen planus and other underlying diseases. The hereditary and idiopathic nature of the disease is underlined and a classific...

The term "parrot beak nail" describes a morphologic change of the nail plate characterized by excessive forward curvature. It may be associated with systemic disease or, most commonly, occurs as an idiopathic finding complicated by delayed nail plate trimming. The characteristics of parrot beak nails in ten men are described, and the features of this acquired nail deformity are reviewed. Of the...

Because standard femoral supracondylar nails have certain disadvantages, they are often replaced by traditional femoral or tibial locked nails. The purpose of this study was to make a biomechanical comparison between both types of traditional locked nails to determine which technique was more suitable for treating unstable femoral supracondylar fractures. Fourteen left Sawbones femurs (Pacific ...

Due to the existence of different races and ethnicities and their different life styles, anatomical structure of people vary from one region of the world to another.

This is a report on the investigation of the diseases of the nails and the surrounding tissues caused by fungus infections. The investigation was confined to the isolation and study of the fungi present in the lesions, which are presumably the causative organisms of the diseases of the nails and the tissues immediately surrounding them, causing perionychia. Only those cases were selected in whi...

Acrylic nails, including sculptured nails and the new ultraviolet-curable gel polish lacquers, have been associated with allergic contact dermatitis (ACD). We report 2 cases of ACD to acrylic nails with severe onychodystrophy and psoriasiform changes including onycholysis and subungual hyperkeratosis. In both cases, the patients did not realize the association between the use of acrylate-based ...
