Prospective Longitudinal

Background: Nail bed defects produce a nail plate dystrophy that is permanent and presents important cosmetic problems. To correct the defect, we used a hard palate mucosal graft. This is a procedure with encouraging outcomes for nail bed scars. Objective: To show our initial experience with the hard palate mucosal graft technique for correcting nail dystrophy or permanent onycholysis secondary to a nail bed scar. Methods: This was a prospective, longitudinal, descriptive, observational study. We included five patients with a traumatic nail bed scar and one patient with congenital dystrophy. Seven nails were treated using a hard palate mucosal graft. Results: All repaired nails had a good outcome, with excellent growth and improvement in nail dystrophy. The patients had surgical recovery in 2 weeks and tolerable pain. Conclusions: This is a relatively easy procedure for experienced surgeons to correct nail dystrophy secondary to a nail bed scar, with good to excellent results.

Objective To characterize the ultrasound findings of the nail plate and nail bed in systemic lupus erythematosus (SLE) and its association with nail dystrophy. Methods Thirty-two SLE patients, 36 patients with osteoarthritis (OA) and 20 healthy individuals were studied. High-frequency linear ultrasound was performed in nails of the second to fifth fingers in all participants. Disease activity (SLEDAI-2K index), accrued organ damage (SLICC/ACR index), autoantibody profile, and Raynaud’s phenomenon were also assessed in SLE patients. Results Nail bed thickness in SLE patients was higher than in healthy individuals (1.25 ± 0.31 mm vs 1.17 ± 0.29 mm; P = 0.01) but lower than in OA (1.39 ± 0.37 mm; P < 0.001), while nail plate thickness was similar among groups. Nail dystrophy was found more frequently in SLE and OA than in healthy individuals. SLE patients with nail dystrophy were older than their counterparts with no dystrophy (39.4 ± 10.4 years vs 27.8 ± 5.6 years; P = 0.004), although nail dystrophy showed no association with SLICC/ACR, SLEDAI-2K, nail bed vascularity, or autoantibodies. Conclusions Nail bed in SLE patients is thicker than in healthy individuals but thinner than in OA patients. Nail dystrophy in SLE is associated with advanced age, but not with accrued organ damage, disease activity, Raynaud's phenomenon, or DIP synovitis assessed by ultrasound.
