Beau lines are transverse, band-like depressions extending from one lateral edge of the nail to the other and affecting all nails at corresponding levels (1). Onychomadesis is considered an extreme form of Beau line with subsequent separation of the proximal nail plate from the nail bed. Both fall along a spectrum of nail plate abnormalities that occur secondary to temporary nail matrix arrest ...

This study designs and evaluates a new nail clipper for the elderly using ergonomic methods. The nail clipper usage problems and requirements were collected first. After requirement analysis we applied ergonomic simulation in redesigning the nail clipper and developing a pedal plate. A usability test was conducted to evaluate both typical and newly developed nail clippers using 20 elder partici...

OBJECTIVE To assess glycation of nail proteins as a tool in the diagnosis of diabetes. METHODS Glycation of nail proteins was assessed using a modified photometric nitroblue tetrazolium-based assay, which provides information about average glucose values of the last 6-9 months. Analysis is possible on 10 mg of nail clippings with a within-run coefficient of variation (CV) of 11%. The analyte ...

Peri-implant fractures distal to an antegrade femoral nail are uncommon injuries, with no current consensus on the best treatment modality. We are presenting three cases of periimplant fractures distal to an antegrade femoral nail. All patients sustained an initial traumatic injury, which was managed with an antegrade femoral nail fixation. They subsequently suffer a second injury which causes ...

Weir Mitchell (1872) and Sharpey-Schafer (1931) reported that section of a nerve supplying cutaneous fibres to the fingers results in a retardation of nail growth. Head and Sherren (1905), however, believed that the slowing of growth observed in these cases wvas due entirely to the immobilization of the limb either as a result of splinting or paralysis and that division of sensory fibres withou...

background:   although intramedullary nailing (imn) is an established and accepted operative treatment for femoral shaft fracture in patients younger than 60, there is a lack of data on the results of this treatment on those over 60. the purpose of this study was to determine if the outcome of imn for femoral shaft fracture in elderly patients is also acceptable. particular challenges in this g...

The nail, a fast-growing organ, is sensitive to changes in the germinal matrix, and, as would be expected, a severe systemic illness can affect the growth rate of the ungual matrix, which occasionally results in temporary growth arrest (Beau’s line). Thus, recovery from growth arrest can be associated with onychomadesis, also called nail shedding, a condition that indicates the separation of th...

BACKGROUND Nail psoriasis occurs in up to 50% of patients affected by psoriasis, with a significant impact on quality of life that leads to a real clinical need for new therapeutic options. AIM To confirm whether the strengthening and hardening properties of the hydroxypropyl-chitosan (HPCH) nail lacquer could improve the structure of the nail plates on psoriatic nails. MATERIALS AND METHOD...

Noninvasive techniques for nail imaging would be useful for confirming diagnosis and monitoring treatment response at the microscopic level in patients with nail psoriasis. However, the use of ultrasound and high-resolution magnetic resonance imaging in nail evaluation is limited. Optical coherence tomography (OCT) produces high-resolution images of transversal tissue sections and represents an...

Introduction: Intramedullary nailing has been used frequently for the treatment of tibial diaphyseal fractures. Chronic anterior knee pain has been considered the most frequent post-operative complication of this technique. We investigated the relationship between anterior knee pain and position of nail tip in proximal tibia. Methods: 103 patients were selected among patients who underwent inte...
