Prerequisite is a healthy nail residue of at leas...

lem causing growth disturbance may lead to the formation of transverse lines across the nail plate, as in Mees’, Muehrcke’s, and Beau’s lines (Figure 2). Changes in the configuration of the capillaries in the proximal nail bed are responsible for some of the alterations that occur in patients with connective tissue disorders, while abnormalities in the periosteal vessels contribute to clubbing....

OBJECTIVE Patients with psoriasis and psoriatic arthritis (PsA) commonly have nail involvement. There is no validated psoriatic nail assessment tool.

Human hereditary nail disorders constitute a rare and heterogeneous group of ectodermal dysplasias. They occur as isolated and/or syndromic ectodermal conditions where other ectodermal appendages are also involved, and can occur associated with skeletal dysplasia. 'Nail disorder, nonsyndromic congenital' (OMIM; Online Mendelian Inheritance in Man) is subclassified into 10 different types. The u...

Two prospective studies of ingrowing toenail management were conducted. In the first, 163 patients (204 ingrowing nail edges) who had not had previous surgery were randomised and treated by total nail avulsion, nail edge excision, or nail edge excision with phenolisation of the germinal matrix; recurrence rates one year postoperatively were 73%, 73% and 9% respectively. In the second study, 63 ...
