Nail biopsy is a safe and useful technique for diagnosis and management of many nail conditions. A basic understanding of nail anatomy and biology is a prerequisite for a successful nail biopsy. The patient must be adequately prepared and there needs to be excellent anesthesia and hemostasis. The type of nail biopsy depends largely on the location of the pathology in the nail unit. The techniqu...

The combined use of recycled concrete aggregate (RCA) and glass fiber reinforced polymer (GFRP) reinforcement in (RC) structures is deemed plausible to achieve sustainable construction. This paper aims examine the effect such a combination (RCA + GFRP reinforcement) on shear behavior RC beams. Six medium-scale beams (150 × 260 2200 mm) critical were tested under three-point loading until failur...

Offshore structures are exposed to risks of vessel collisions and impacts from dropped objects. Tubular members extensively used in offshore construction, thus, there is scope investigate their crashworthiness behaviour. Aluminium, glass fibre reinforced polymer (GFRP) hybrid aluminium/GFRP circular tube specimens were fabricated then tested under quasi-static dynamic axial loading conditions. ...

We hypothesised that Hansen Solubility Parameters (HSPs) can be used to predict drug-nail affinities. Our aims were to: (i) determine the HSPs (δD, δP, δH) of the nail plate, the hoof membrane (a model for the nail plate), and of the drugs terbinafine HCl, amorolfine HCl, ciclopirox olamine and efinaconazole, by measuring their swelling/solubility in organic liquids, (ii) predict nail-drug inte...

background & aim : pulse oximetry is a frequently used and standard non-invasive method for monitoring oxygen (o2)-saturation in blood. many factors including dark skin and pigmentation may effect on rate of saturation of the blood oxygen absorbed by pulse oximetry. the effect of nail polish and/or henna color on blood oxygen has not been yet identified and the present study has been carried ou...

This study compared patients who underwent treatment with short or long cephalomedullary nails with integrated cephalocervical screws and linear compression. Patients with AO/OTA 31-A2 or A3 pertrochanteric fractures treated with either short (n=72) or long (n=97) InterTAN (Smith & Nephew, Memphis, Tennessee) cephalomedullary nails were reviewed. Information on perioperative measures (estimated...

The nail unit is constructed by distinctly regulated components. The nail isthmus is a lately proposed region as a transitional zone between the most distal part of the nail bed and the hyponychium. It is difficult to recognize the nail isthmus in the normal nail, but it is easy to identify the region in nail disorders such as pterygium inversum unguis and ectopic nail. We describe structure an...

Yellow nail syndrome is a rare disease of unclear etiology. We describe a patient who develops yellow nail syndrome, with primary nail and sinus manifestations, shortly after amalgam dental implants. A study of the patient's nail shedding showed elevated nail titanium levels. The patient had her dental implants removed and had complete resolution of her sinus symptoms with no change in her nail...

The purpose of our study was to compare the proximal femoral nail antirotation (PFNA; Synthes, Paoli, Pennsylvania) with a reconstruction nail (Recon; Zimmer, Warsaw, Indiana) in the treatment of comminuted proximal femoral fractures. Between 2003 and 2010, twenty-three consecutive patients with AO/Orthopaedic Trauma Association 31-A3 fractures combined with proximal 32 fractures who had a mini...
