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...

Over the past few years, there has been an increase in cases of allergic contact dermatitis caused by acrylates, because of the growing popularity of artificial nails. Pathological reactions to artificial nails typically occur on or around the nail area. Eyelid contact dermatitis due to artificial nails is rarely seen, especially in a nonoccupational setting. The authors report the case of a 45...

Yellow nail syndrome was defined in 1964 as a combination of slow growing, discoloured nails and edema (Samman & White, 1964). The rate of growth of finger nails was less than 0.2 mm per week compared with the normal 0.5-1.2 mm per week. The nails were thickened and the cuticles were deficient. The color varied from pale yellow to slightly greenish. Onycholysis (separation of the nail from its ...

Age-related changes in phospholipid and free cholesterol contents of hindleg muscles from normal and dystrophic (C57BL/6J dy/dy) mice were investigated. Free cholesterol contents in liver, whole blood and brain of dystrophic mice at 3 weeks of age were also compared with the control. Free cholesterol content tended to increase in the liver of the dystrophic mouse. Free cholesterol content of dy...

Interactins between skeletal muscle protein and amino acid metabolism were investigated using C57BL and 129ReJ mice with hereditary muscular dystrophy. On incubation, hind limb muscle preparations from dystrophic mice released large quantities of amino acids, particularly alanine and glutamine which were increased 70% and 40% compared to muscles from carrier or control mice. The increased alani...

Ingrown nails are defined as inflammation of the lateral nail fold that is caused by penetration by the nail plate and associates with pain and/or infection. The pain associated with ingrown nail hampers walking, raises the risk of falls, and decreases the quality of life. The Sogawa method is a novel conservative medical treatment for ingrown nails that is based on stainless steel wire. It was...

Rotational deformity following intramedullary nailing may cause symptoms and require surgical correction by osteotomy. Reamed, locked intramedullary nailing may be performed, but concern about cortical blood supply and potential pulmonary dysfunction from reaming have led many surgeons to limit this and use smaller diameter nails. Slotted nails are commonly used but are less stiff in torsion th...
