“When our fingers and toes are submerged in water, the sympathetic nervous system triggers the blood vessels in our fingers and toes to constrict, causing skin wrinkles,” explains Ashley ...
Maceration often occurs with the application of a bandage to a wound, regardless of its mildness or severity, particularly if the bandage prevents water from evaporating from the surface of the skin. This occurs because the skin under the bandage becomes wet due to perspiration, urine or other bodily fluids, or contact with other liquids. The ...
The wrinkle test (attributed as O'Riain's or Leukens' wrinkle test) is a test of peripheral nerve function. The fingers are placed in warm water for approximately 10–40 minutes. If the fingers do not wrinkle, this is a sign of denervation. [1] [2]
Prior to a 1935 study, the common explanation was based on water absorption in the keratin-laden epithelial skin when immersed in water, [16] causing the skin to expand and resulting in a larger surface area, forcing it to wrinkle. Usually the tips of the fingers and toes are the first to wrinkle because of a thicker layer of keratin and an ...
Erosio interdigitalis blastomycetica (EIB) is a skin condition caused by a Candida albicans infection, characterised by an oval-shaped area of macerated white skin on the web between and extending on to the sides of the fingers. [1]: 310
Wrinkly skin syndrome (WSS) is a rare genetic condition characterized by sagging, wrinkled skin, low skin elasticity, and delayed fontanelle (soft spot) closure, along with a range of other symptoms. [1] The disorder exhibits an autosomal recessive inheritance pattern with mutations in the ATP6V0A2 gene, leading to abnormal glycosylation events ...
