Onycholysis is a common medical condition characterized by the painless detachment of the nail from the nail bed, usually starting at the tip and/or sides. [1] On the hands, it occurs particularly on the ring finger but can occur on any of the fingernails. It may also happen to toenails. Onycholysis can occur in many conditions, including ...
The thick curved nail is difficult to cut, and often remains untrimmed, exacerbating the problem. Onychomycosis in every nail of the right foot. Onycholysis is a loosening of the exposed portion of the nail from the nail bed, usually beginning at the free edge and continuing to the lunula.
Onychomadesis is defined by the nail plate's detachment from the matrix, its continuous connection to the nail bed, and, frequently but not always, shedding. [4] Beau lines are transverse ridges on the nail plates. [5] Onychomadesis might be considered a more severe version of Beau lines. [6]
Psoriatic nails are characterized by a translucent discolouration in the nail bed that resembles a drop of oil beneath the nail plate. [2] Early signs that may accompany the "oil drop" include thickening of the lateral edges of the nail bed with or without resultant flattening or concavity of the nail; separation of the nail from the underlying nail bed, often in thin streaks from the tip-edge ...
A bed of nails is an oblong piece of wood, the size of a bed, with nails pointing upwards out of it. [1] While it appears at first glance that anyone lying on such a "bed" would be injured by the nails, if the nails are numerous enough, the weight is distributed among them so that the pressure exerted by each nail is not enough to puncture the ...
Muehrcke's lines were described by American physician Robert C. Muehrcke (1921–2003) in 1956. In a study published in BMJ, he examined patients with known chronic hypoalbuminemia and healthy volunteers, finding that the appearance of multiple transverse white lines was a highly specific marker for low serum albumin (no subject with the sign had SA over 2.2 g/dL), was associated with severity ...
Pincer nail is characterized by an increase in the nail's maximum transverse curvature, pushing the nail edges down into the lateral nail fold. The nail bed at the distal end along the longitudinal axis of the nail plate is also pushed down in a proximal to distal manner.
The condition is thought to be due to a decrease in vascularity and an increase in connective tissue within the nail bed; [3] the darker shade of the distal portion of the nail fades upon pressure, which differentiates Terry's nails from Lindsay's nails.
