BACKGROUND The radius of curvature (ROC) misfit of cephalomedullary nails during anterograde nailing can lead to complications such as distal anterior cortical encroachment. This study quantified the anatomical fit of a new nail with 1.0-m ROC (TFN-ADVANCED(™) Proximal Femoral Nailing System [TFNA]) compared with a nail with 1.5-m ROC (Gamma3 Long Nail R1.5 [Gamma3]). METHODS We generated 63 ...

Nail disorders are very common, and about 50% of all nail conditions are of fungal etiology. A proper diagnosis is essential because many nail conditions look alike. Diagnosis and treatment of other nail disorders, such as psoriasis, lichen planus, and neoplasms, are discussed.

Background: Nail biting (NB) is a common, but unresolved, problem in psychiatry, psychology, medicine and dentistry. It is the habit of biting one’s nails, is commonly observed in both children and young adults Materials & Methods: The study was a comparative cross‐ sectional microbiological study, conducted on the saliva samples of 40 chronic nail biting subjects in that 20 were males and 20 w...

PURPOSE OF STUDY To measure the pH of the surface of healthy nail plates. PROCEDURES The surface pH of human fingernails and big toenails was measured in vivo using a skin pH meter. The influence of washing, anatomical site (fingers/toes), side (left/right), digit (digits 1-5) and gender was determined. The pH of the nail interior was also measured. RESULTS The pH of the nail plate surface ...

Nails are considered epidermal appendages, and as such, are commonly affected in patients with psoriasis, 80% of whom are likely to develop nail psoriasis as a result of their condition. Two patterns of nail disorders have been shown to be caused by psoriasis. Nail matrix involvement can result in features such as leukonychia, pitting (punctures or cupuliform depressions), red spots in the lunu...

Nail is a tool that greatly reduces the programmer effort for safely parsing and generating data formats defined by a grammar. Nail introduces several key ideas to achieve its goal. First, Nail uses a protocol grammar to define not just the data format, but also the internal object model of the data. Second, Nail eliminates the notion of semantic actions, used by existing parser generators, whi...

BACKGROUND Pincer nail is a nail deformity characterized by transverse overcurvature of the nail plate. Pincer nail can affect a patient's quality of life due to its chronic, recurrent course; however, there have been no clinical studies on the pincer nail condition in Korean patients. OBJECTIVE The purpose of this study was to characterize the clinical findings and treatment of pincer nail. ...

Three hundred leprosy patients were recruited to study the pattern and frequency of nail changes. Nail changes, like longitudinal ridging in finger nails, transverse striations involving both finger and toe nails etc. which occurred with similar frequency in the PB and MB patients in comparison with the control group, were excluded from the analysis. Out of a total number of 150 PB patients, 84...

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...

BACKGROUND Nail apparatus melanoma is known to be associated with a poor prognosis, mainly because of a delay in diagnosis that is made at an invasive stage. This delay is particularly true in cases involving amelanotic melanoma. To our knowledge, only 1 case of in situ amelanotic melanoma of the nail unit has previously been described. We report 3 cases of in situ amelanotic melanoma with clin...
