The etiology, infectious agent, and treatment are usually different for each form, and the 2 forms are often considered separate entities. It can start suddenly (acute Paronychia) or gradually (chronic Paronychia). Paronychia disease is an infection of the inflammation skin and soft tissue infections that surrounds a toenail or fingernail. Other infectious organisms may be involved, and if left untreated, the nail plate may separate from the nail bed and crumble off. As the infection progresses, organic debris accumulates under the nail plate often discoloring it. The fungus digests the keratin protein of which the nail plate is comprised. It normally appears white or yellowish in color, and may also change the texture and shape of the nail. This type of infection is characterized by Onycholysis (nail plate separation) with evident debris under the nail plate.
Nail Diseases & Infection Fungal or Yeast InfectionĪ fungal or yeast infection which results in Onychomycosis can invade through a tear in the proximal and lateral nail folds as well as the Eponychium. Finally, the nail functions as a tool, enabling for instance a so-called "extended precision grip" (e.g. The nail then acts as a counterforce when the end of the finger touches an object, thereby enhancing the sensitivity of the fingertip, even though there are no nerve endings in the nail itself. It also serves to enhance precise delicate movements of the distal digits through counter-pressure exerted on the pulp of the finger. A healthy (finger)nail has the function of protecting the distal phalanx, the fingertip, and the surrounding soft tissues from injuries.
