A variety of itching, often encountered in the eczema of elderly people, is formication; this is described as exactly like the crawling of myriads of animals over the skin. It is probably due to the successive irritation of nerve fibrils in the skin. At times patients who suffer from it will scarcely be persuaded that it is not due to insects.
[1] [2] [3] In the elderly, xerosis, is the most common cause for an itch due to the degradation of the skin barrier over time. [4] However, the cause of senile pruritus is not clearly known. [ 5 ] Diagnosis is based on an elimination criteria during a full body examination that can be done by either a dermatologist or non-dermatologist physician.
OTC skin protectants like zinc acetate, zinc carbonate, zinc oxide, and calamine can also help dry the oozing and weeping, while baking soda or colloidal oatmeal may help with the itch, the FDA ...
Itch is readily abolished in skin areas treated with nociceptor excitotoxin capsaicin but remains unchanged in skin areas rendered touch insensitive by pretreatment with anti-inflammatory saponins. Although experimentally induced itch can still be perceived under a complete A-fiber conduction block , it is significantly diminished.
The area of skin involved can vary from small to the entire body. [149] [150] Diagnosis – Medical diagnosis (abbreviated Dx [151] or D S) is the process of determining which disease or condition explains a person's symptoms and signs. It is most often referred to as diagnosis with the medical context being implicit.
Atopic dermatitis is also associated with the release of pruritogens (molecules that stimulate pruritus or itching) in the skin. [33] Keratinocytes, mast cells , eosinophils and T-cells release pruritogens in the skin; leading to activation of Aδ fibers and Group C nerve fibers in the epidermis and dermis contributing to sensations of pruritus ...
Constant scratching causes the skin to thicken. The thickened skin itches, causing more scratching, causing more thickening. Affected area may spread rapidly through the rest of the body. Many hypothesize LSC has a psychosomatic origin. [3] Those predisposed to itch as a response to emotional tensions may be more susceptible to the itch-scratch ...
Flushing is to become markedly red in the face and often other areas of the skin, from various physiological conditions. Flushing is generally distinguished from blushing, since blushing is psychosomatic, milder, generally restricted to the face, cheeks or ears, and generally assumed to reflect emotional stress, such as embarrassment, anger, or romantic stimulation.
