Pulse oximetry (Spo2) is a simple, noninvasive method that is widely used to determine oxygen saturation in patients undergoing surgical procedures. Artificial acrylic nails have recently become fashionable to strengthen and lengthen nails. This study investigates the effect of unpolished acrylic nails on the measurement of oxygen saturation by pulse oximetry. Data were collected during a 3-mon...

Until very recently, analysis of bone biopsies by means of the method of electron paramagnetic resonance (EPR) collected after surgery or amputation has been considered as the sole reliable method for radiation dose assessment in hands and feet. EPR measurements in finger- and toenail have been considered for accident dosimetry for a long time. Human nails are very attractive biophysical materi...

background and objectives: pulse oximetry is the most common technique for monitoring hemoglobin oxygen saturation (spo2). different colors and brands of nail polish may cause disturbance in the reading and interpretation of oxygen saturation. the aim of this study was to determine the effect of different colors of nail polish on oxygen saturation measured by pulse oximeter. methods: thirty hea...

Punctate leukonychia is particularly frequently seen in young girls when they start to perform their own manicure. It is thought to be of traumatic origin, but this only explains a part of the cases. Punctate und short striate leukonychia is often a sign of a hammer blow when it overlies a subungual hematoma. Crush injuries are usually bigger (Figure1). Transverse leukonychia may be a sign of l...

INTRODUCTION: It is common knowledge that the fracture healing process is strongly influenced by the mechanical behaviour of the bone implant complex (BIC) due to the resulting interfragmentary movement (IFM) of the bone fragments at the fracture site. Unreamed intramedullary nailing reduces the disturbance of blood supply in comparison to reamed nailing but leads to a more flexible stabilizati...

The terms onychocryptosis, 'ingrowing nail' and 'ingrown nail' are used in various localities to indicate degrees of severity but for the purpose of this article they will be applied as synonyms to describe a condition where a portion of the side of the nail plate has actually penetrated the epidermis and dermis of the nail groove to produce a wound. The condition may or may not be further comp...

Hereditary ectodermal dysplasia is an inherited disorder involving skin, hair, nails and teeth. Two main clinical forms have been described--hypohidrotic type and hidrotic type. A case of ectodermal dysplasia with absence of hypohidrosis and defective nails has been reported. The importance of early prosthetic management has been discussed.

Elastic stable intramedullary nailing (ESIN) is a minimally invasive technique. According to this technique, two elastic nails are introduced through the metaphysis into the medullary canal, advanced through the fracture site and impacted into the opposite metaphysis. These nails are preformed in a C-shaped manner, which allows for their precise orientation and the creation of an elastic system...
