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...

Nail-patella syndrome is an autosomal dominant disorder characterized by dyplasia of finger nails, skeletal anomalies, and, frequently, renal disease. It has recently been shown that this disorder is caused by putative loss-of-function mutations in a transcription factor (LMX1B) belonging to the LIMhomeodomain family, members of which are known to be important for pattern formation during devel...

Physical examination revealed both great toenails to have marked thickening of the nail plate with closely spaced transverse superficial ridging, lack of luster, and dark tanyellowish discoloration (...

Green nail syndrome (GNS) caused by Pseudomonas aeruginosa is the most common bacterial nail infection. The treatment of GNS is challenging in many cases and recommendations based on clinical trials are lacking. We report two cases with GNS successfully treated with off-label use of topical nadifloxacin, a fluoroquinolone approved for acne and bacterial skin infections in some countries.

INTRODUCTION Nail patella syndrome is a rare autosomal dominant hereditary condition, with an incidence of 22 per million in the United Kingdom. The syndrome's most common features include iliac horns, hypoplastic patella and nail dysplasia. CASE PRESENTATION We report the case of a 26-year-old Caucasian man with nail patella syndrome who sustained a fracture of his right hypoplastic patella ...
