Referred itch (original) (raw)
Referred itch or mitempfindung is the phenomenon in which a stimulus applied in one region of the body is felt as an itch or irritation in a different part of the body. The syndrome is relatively harmless, though it can be irritating, and healthy individuals can express symptoms. Stimuli range from a firm pressure applied to the skin – a scratch – to irritation or pulling on a hair follicle on the skin. The referred sensation itself should not be painful; it is more of an irritating prickle leading to the compulsion to scratch the area. The stimulus and referred itch are ipsilateral (the stimulus and the referred itch occur on the same side of the body). Also, because scratching or putting pressure on the referred itch does not cause the stimulus area to itch, the relationship between the

| dbo:abstract | Referred itch or mitempfindung is the phenomenon in which a stimulus applied in one region of the body is felt as an itch or irritation in a different part of the body. The syndrome is relatively harmless, though it can be irritating, and healthy individuals can express symptoms. Stimuli range from a firm pressure applied to the skin – a scratch – to irritation or pulling on a hair follicle on the skin. The referred sensation itself should not be painful; it is more of an irritating prickle leading to the compulsion to scratch the area. The stimulus and referred itch are ipsilateral (the stimulus and the referred itch occur on the same side of the body). Also, because scratching or putting pressure on the referred itch does not cause the stimulus area to itch, the relationship between the stimulus and the referred itch is unidirectional. The itching sensation is spontaneous and can cease with continued stimulation. There are two types of referred itch: normal and acquired (pathological). Normal mitempfindung is usually detected in early childhood and persists for the majority, if not the rest, of the individual's life. Acquired or pathological mitempfindung is the effect of damage to the central nervous system and only lasts for a short period of time. Symptoms are variable among affected individuals, but it is widely accepted that the soles of the feet, palms, and the face are never affected by mitempfindung. There is no evidence of genetic influence on referred itch. There is a published study, however, that mentions an affected man whose children were also affected. Much is still unknown about the physiological mechanisms of the phenomenon, and no single theory is accepted. Research and information regarding mitempfindung is limited and dated. Most research on the topic was conducted in the late 19th century, and the most recent publications occurred in the late 1970s. A handful of studies were done in the early 1990s, but further data must be collected and interpreted before a thorough understanding of mitempfindung is reached. (en) |
