Finger nail plate shape and size for personal identification – a possible low technology method for the developing world - Preliminary report

Stature is fundamental in personal identification for forensic and physical anthropologists. When a full skeleton is not available, stature can be estimated from incomplete human remains. It is also important to apply a method to estimate the stature based on the same specific population of the remains. For this purpose, we measured 4 distances between cephalometric landmarks of the mandible and the stature in 56 subjects (both males and females) from Caucasian Italian population. The correlation between these parameters appeared to be statistically significant, so that it was possible to establish a regression equation to estimate the stature from the mandible in this population.

A series of 66 patients, aged between 1 and 70 years, with 70 disruptive injuries to finger nails was reviewed. The injuries were treated by cleaning of the finger, evacuation of haematoma and anatomical replacement of the nail plate, or a substitute, which was secured with a modified dorsal tension band suture without formal repair of the nail bed. K-wire fixation of the distal phalanx was employed only in the event of displaced fracture of the distal phalanx, complete absence of the nail plate and laceration extending to the distal pulp. This simple method, which bypasses the injured and friable, but vital nail structures resulted in uncomplicated reformation of the normal nail plate in all of the cases. Removal of the nail plate and formal repair of the nail bed is not necessary in any age group with finger nail disruptions.

Abstract Background Nail bed trauma is one of the most common surgically treated paediatric hand injuries in the UK. Despite surgeons generally expressing a preference to replace the nail plate after repairing the nail bed, there is limited evidence to support this practice. We describe a statistical and health economic analysis plan (SHEAP) for the Nail bed INJury Analysis (NINJA) randomised controlled trial. Methods/design NINJA is a multicentre, pragmatic, superiority, parallel group randomised controlled trial of the treatment of nail bed injury in participants 16 years old or younger. The study aims to evaluate the efficacy and cost-effectiveness of replacing the nail plate compared to discarding it following the repair of a nail bed injury. Surgical site infection at 7–10 days post-randomisation and cosmetic appearance of the nail are the co-primary outcomes for NINJA. Surgical site infection at 7–10 days post-randomisation will be evaluated using a logistic regression model adjusting for site as the sole stratification factor and allowing for intra-site correlation. Cosmetic appearance will be assessed via the newly developed Oxford Finger Nail Appearance Score and will be evaluated by use of a Mann-Whitney U test. An ordinal logistic regression model will also be used to assess the Oxford Finger Nail Appearance Score, adjusting for site and allowing for intra-site correlation. Secondary outcomes are measured at 7–10 days and 4 months and include the EQ-5D-Y questionnaire, pain at first dressing change, cost-effectiveness, late surgical site infection, and participant/parent satisfaction with nail healing. Missing primary outcome data will be summarised by treatment arm and investigated through a sensitivity analysis. Full details of the planned methods of analysis and descriptive statistics are described in this paper. The NINJA study protocol has been published previously. Discussion The planned analysis strategy for the NINJA trial has been set out here to reduce the risk of reporting bias and data-driven analysis. Any deviations from the SHEAP described in this paper will be detailed and justified fully in the final report of the trial. Trial registration ISRCTN, ISRCTN44551796. Registered on 23 April 2018.

The Relationship

This study examines the relationship between the shape of the nail plate of the hallux and the base of its distal phalanx. Twenty-three cadaver specimens were examined anatomically for nine variables. These variables represented the following: height and width of the distal phalanx base; height and width of the proximal aspect of the nail plate; distal shape of the nail plate; ratio of the nail plate height and width and structural index of the nail plate. Statistics for the variables are presented using correlation coefficients between nail structural index and bone structural index. The study shows a high and significant correlation between the shape of the proximal aspect of the nail plate and that of the phalangeal base.

In the course of several 21-cm observing programmes being carried out by the Leiden Observatory with the 25-meter telescope at Dwingeloo, a fairly complete, though inhomogeneous, survey of the regionl11= 0° to 66° at low galactic latitudes is becoming available. The essential data on this survey are presented in Table 1. Oort (1967) has given a preliminary report on the first and third investigations. The third is discussed briefly by Kerr in his introductory lecture on the galactic centre region (Paper 42). Burton (1966) has published provisional results of the fifth investigation, and I have discussed the sixth in Paper 19. All of the observations listed in the table have been completed, but we plan to extend investigation 3 to a much finer grid of positions.

Shape And Size

The pore spaces in sandstones are the result of the original depositional fabric and the degree of post-depositional alteration that the rock has experienced. The largest pore volumes are present in coarse-grained, well-sorted materials with high sphericity. The chief mechanisms which alter the shape and size of the pores are precipitation of cementing agents and the dissolution of soluble components. Each process may operate alone or in combination with the other, or there may be several generations of cementation and solution.The scanning electron microscope has ‘been used in this study to reveal the morphology of the pore spaces in a variety of moderate porosity, orthoquartzites.
