BACKGROUND Previous authors have claimed that dehydration of the nail plate causes brittle nails. Some experts claim that normal nails contain 18% water, and brittle nails contain less than 16%. OBJECTIVE We sought to test the hypothesis that brittle nails contain 2% less water than normal nails. We also examined the relationship between a number of health and behavioral variables and brittle...
Flexible intramedullary nails are commonly used to treat femoral fractures in children. This study evaluated the biomechanical differences between stainless steel and titanium nails when securing transverse and comminuted fractures in a synthetic femur model. Retrograde flexible stainless steel and titanium nails placed in a divergent "C" pattern were mechanically tested, and axial rotation and...
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...

Pathologic hoof changes in horses and swine can be normalized by administration of biotin. This vitamin has been given orally to women with brittle fingernails or onychoschizia. The aim of the study was to test whether the favorable clinical results could be corroborated by scanning electron microscopy. We investigated the distal ends of the fingernails from 32 persons. They were placed into th...
The fluoride content in the urine, hair, and nails of 106 workers employed in a phosphate fertiliser plant was significantly raised above the control level. Positive correlations were found between the group means for concentrations of fluorides in urine and hair (r = 0.77), urine and nails (r = 0.99), and hair and nails (r = 0.70). Individual values in the whole population gave significant cor...
