Onychorrhexis also known as brittle nails, is brittleness with breakage of fingernails or toenails. Paronychia is a bacterial or fungal infection where the nail and skin meet. Koilonychia is when the nail curves upwards (becomes spoon-shaped) due to an iron deficiency. The normal process of change is: brittle nails, straight nails, spoon-shaped ...
The most common symptom of a fungal nail infection is the nail becoming thickened and discoloured: white, black, yellow or green. As the infection progresses the nail can become brittle, with pieces breaking off or coming away from the toe or finger completely.
Green nail syndrome is an infection that can develop in individuals whose hands are frequently submerged in water resulting in discolouration of the nails from shades of green to black. [ 3 ] [ 4 ] It may also occur as transverse green stripes that are ascribed to intermittent episodes of infection. [ 3 ]
Onychomadesis is a periodic idiopathic shedding of the nails beginning at the proximal end, possibly caused by the temporary arrest of the function of the nail matrix. [1]: 784 [2]: 660 One cause in children is hand, foot, and mouth disease. [3] This generally resolves without complication.
While ingrown nails can occur in the nails of both the hands and the feet, they occur most commonly with the toenails (as opposed to fingernails). [citation needed] A common misconception is that the cause of an ingrown toenail is the nail growing into the paronychium, but it can also be caused by overgrown toe skin. [2]
Flat feet (Pes planus foot) essentially means that the arch inside the foot is flat. This very common painless disorder may occur at birth or after pregnancy. Flat feet generally do not cause problems but may sometimes cause the foot to rotate inwards (pronation). There are orthotic shoe insoles (foot orthotics) that help correct flat feet.
Hand, foot, and mouth disease (HFMD) is a common infection caused by a group of enteroviruses. [10] It typically begins with a fever and feeling generally unwell . [ 10 ] This is followed a day or two later by flat discolored spots or bumps that may blister, on the hands, feet and mouth and occasionally buttocks and groin.
The pressure of the blood blister may cause separation of nail plate from the nail bed (onycholysis), but the nail should not be pulled off, as this can cause scarring of the nailbed and deformed nails. [3] Nail discolouration may last some months. [4] The nail plate may also become thicker and more brittle as a result of the injury ...
