Brittle Nails Syndrome is characterized by fragility of the nail plate, affecting 27% of women. We evaluated dermatology patients in a cross-sectional study about perception of nail fragility. One hundred and thirty eight women were included, with median age of 36.5 years. Nail examination showed changes in 57% and 49% reported nail fragility. The first three fingernails were the most affected....

The scarcity of specific submission protocols for nail unit biopsies presents many challenges for appropriate specimen processing. Many nail biopsies are received fragmented or without orientation, often resulting in less-than-ideal tissue embedding and poor histologic sections, which are difficult to interpret. Methods are described for proper nail matrix/bed biopsy and plate submission that i...

A case of nail gun injury is reported. Preoperative radiographs are essential to determine whether copper barbs project from the nail shaft before any attempt is made to remove the nail. Thorough exploration is required.

The authors report the case of a young patient in which, during removal of a Seidel nail four years after healing of a mid shaft fracture of the humerus, bone formation into the central canal of the nail through the peripheral slots, prevented the three spread distal fins of the nail to close. The nail could only be extracted by forceful use of the extracting instrument, fortunately without com...

In an effort to increase the efficacy of topical medications for treating onychomycosis, several new nail penetration enhancers were recently developed. In this study, the ability of 10% (wt/wt) miconazole nitrate combined with a penetration enhancer formulation to permeate the nail is demonstrated by the use of a selection of in vitro nail penetration assays. These assays included the bovine h...

The authors present a case of onychomatricoma, a rare benign tumour of the nail matrix, first described by Baran and Kint in 1992. The lesion appeared on the proximal nail fold, covering half the nail of the second left finger. The nail was thickened and yellowish with longitudinal melanonychia. It was surgically removed with very satisfactory aesthetic results even after 5 years. A review on t...

A 25-year-old man presented with hook nail and painful atrophic pulp over the tip of the terminal phalanx of the right thumb 3 months following a crush injury. Lateral nail folds were poorly defined and the nail was curved. The patient was unable to pick up objects with a precision pinch. Reconstruction was performed with Atasoy antenna procedure. One year later, normal pulp contour of the inju...

768 Ann Dermatol Fig. 1. (A) Close-up view of the ectopic nail showing a bipartite structure. The root of the detached nail located on the distal phalanx extending through the proximal nail fold (PNF). (B) Both parts are separated with longitudinal incision and oblique incisions were made at the both corners of PNF. Care should be taken not to damage main matrix and insertion of tendon. (C) No ...
