onychology

What! Another Book on Nails? The decade of the 1980s provided an explosive interest in the diagnosis and treatment of nail disorders. An area of dermatology long neglected by clinical and basic science-research people as well, onychology has rather suddenly become fashionable. The nail unit is no longer regarded as untouchable or an appendage to be ignored. Suddenly, investigators are peering into the chemistry, physiology, and development of the nail. Cell biology, electron microscopy, ultrasound, and numerous other sophisticated research techniques and methodologies are being applied to the study of the onychium and how it works.
