Artificial nails

M J L Bucx, P Krijtenburg, G J Scheffer
- An increasing number of patients wear nail polish, artificial nails or have piercings.- There is uncertainty about the perioperative management of these items, especially when located outside the surgical area.- In the majority of hospitals, patients are urged to remove these items preoperatively, under the assumption that they might cause problems.- Frequently, however, these items cannot be removed straightforwardly.- Nail polish and artificial nails only very rarely cause perioperative problems and therefore do not need to be removed pre-operatively...

PURPOSE: New research is focusing on the use of autologous growth factors to increase the effect of bone fracture healing while decreasing the amount of healing time for the patient. Platelets have been demonstrated to be the natural storage vessel for several growth factors and cytokines that promote blood coagulation, tissue repair, and the process of bone mineralization. The present study aims to evaluate the role of platelet-rich plasma (PRP) in healing of acute femoral shaft fractures radiologically...

Having long artificial (acrylic) nails is a current fashion trend, and they are becoming an increasingly popular cosmetic enhancement. We believe that they can be a potential burn hazard to their unknowing users. We present the first reported case in medical literature of a woman whose acrylic nail ignited from a cigarette butt a short distance from the nail while she was taking the final puffs. She sustained a full thickness burn to her dominant left thumb, resulting in terminalisation. Acrylic nails are very flammable and, once ignited, they burn to completion, with the source of flame removed...

OBJECTIVES: Fluoride toothpaste has been extensively used to prevent dental caries. However, the risk of fluorosis is concerning, especially in young children. Calcium phosphate has been an effective remineralizing agent and is present in commercial dental products, with no risk of fluorosis to users. This in vitro study aimed to compare the effects of different calcium phosphate compounds and fluoride-containing dentifrices on artificial caries in primary teeth. MATERIALS AND METHODS: Fifty sound primary incisors were coated with nail varnish, leaving two 1 mm(2) windows on the labial surface before immersion in demineralizing solution for 96 hours to produce artificial enamel lesions...

Acrylates are molecules that are well known for their strong sensitizing properties. Historically, many beauticians and individuals using store-bought artificial nail products have developed allergic contact dermatitis from acrylates. More recently, the use of acrylic nails among flamenco guitarists to strengthen their nails has become very popular. A 40-year-old non-atopic male patient working as a flamenco guitarist developed dystrophy, onycholysis and paronychia involving the first four nails of his right hand...

Exposure to ultraviolet-A (UVA) light can accidentally cause adverse effects in the skin and eyes. UVA induces DNA damage directly by creating pyrimidine dimers or by the formation of reactive oxygen species that can indirectly affect DNA integrity. UVA radiation is emitted by lamps from everyday devices. In adult rats, micronucleated erythrocytes (MNE) are removed from the circulation by the spleen. However, in newborn rats, MNE have been observed in peripheral blood erythrocytes. The objective of this study was to use micronucleus tests to evaluate the DNA damage caused in newborn rats exposed to UVA light from three different types of UVA lamps obtained from commonly used devices: counterfeit detectors, insecticide devices, and equipment used to harden resins for artificial nails...

Unstable intertrochanteric fractures are commonly treated with a cephalomedullary nail due to high failure rates with a sliding hip screw. The Omega3 Trochanteric Stabilizing Plate is a relatively new device that functions like a modified sliding hip screw with a proximal extension; however, its mechanical properties have not been evaluated. This study biomechanically compared a cephalomedullary nail, that is, Gamma3 Nail against the Omega3 plate. Unstable intertrochanteric fractures were created in 24 artificial femurs...

Tibial shaft fractures are among the most common long bone fractures in humans. The incidence is 1-2 per 100,000. The gold standard of treatment for AO type 42 A-C fractures is a locking intramedullary nail. The development of new implants has extended the indications for this minimally invasive technique, so that now AO types 41 and 43 can also be treated with special nails. Fixed-angle screw anchors increase primary stability and supplemental locking devices located proximally and distally extend the spectrum of use to metaphyseal fractures...

INTRODUCTION: Artificial models can be useful at approximate and qualitative research, which should give the preliminary results. Artificial models are usually made of photo-elastic plastic e.g.. juvidur, araldite in the three-dimensional contour shape of the bone. Anatomical preparations consist of the same heterogeneous, structural materials with extremely anisotropic and unequal highly elastic characteristics, which are embedded in a complex organic structure. THE AIM OF THE STUDY: Examine the budget voltage and deformation of: dynamic compression plate (DCP), locking compression plate (LCP), Mitkovic internal fixator (MIF), Locked intramedullary nailing (LIN) on the compressive and bending forces on juvidur and veal bone models and compared the results of these two methods (juvidur, veal bone)...

OBJECTIVES: To assess the re-hardening potential of enamel matrix derivatives (EMD) and self-assembling peptides in vitro, hypothesizing that these materials may increase the mineralization of artificial carious lesions and improve hardness profiles. MATERIAL AND METHODS: Forty-eight enamel samples were prepared from extracted bovine lower central incisors. After embedding and polishing, nail varnish was applied, leaving a defined test area. One third of this area was covered with a flowable composite (non-demineralized control)...

Cosmetic embellishment of fingernails involves the use of substance that harden either after the evaporation of solvents (varnishes) or after polymerisation (artificial acrylic nails, gel tips, glue-on artificial nails). Pathological reactions to cosmetics usually occur at a remote site for varnishes, and, most commonly, in situ with polymerising substances. Unvarnished artificial nails do not affect pulse oximetry readings, and in theory, patients are not required to remove them. However, a real problem of contamination via artificial nails exists...

This article demonstrates an example of a wearable chemical sensor based on a fingernail platform. Fingernails represent an attractive wearable platform, merging beauty products with chemical sensing, to enable monitoring of our surrounding environment. The new colorimetric pH fingernail sensor relies on coating artificial nails with a recognition layer consisted of pH indicators entrapped in a polyvinyl chloride (PVC) matrix. Such color changing fingernails offer fast and reversible response to pH changes, repeated use, and intense color change detected easily with naked eye...

Onycholysis is the detachment of the nail plate from the nail bed. If drug-induced, it can be an isolated phenomenon, but it may also accompany or follow a cutaneous phototoxicity reaction due to drug intake and exposure to ultraviolet irradiation. Photo-onycholysis is a rare photosensitivity reaction due to exposure to either a natural or artificial source of light. Many drugs are responsible for this phototoxic reaction, especially tetracyclines, psoralens, chloramphenicol, non-steroidal anti-inflammatory drugs, fluoroquinolones, and, rarely, doxycycline...
