Onycholysis (drug-induced). This word means separation (-lysis) of nails
(onycho-) from nail beds. There are many causes for such a development. The
commonest are mechanical. Nails worn long are frequently lifted by being
snagged. Excessive soaping and soaking in heavy housework promote separation.
The illustration here is of another cause, namely, an idiopathic response by
photosensitivity in a patient who had been taking demethylchlortetracycline.
Doxycycline also does this.
