Glossary for Pruritus

Medical terms related to Pruritus or mentioned in this section include:

  • Acanthocheilonemiasis: A rare tropical infection caused by a particular threadworm usually found in Africa. It may cause skin rashes, muscle and joint pains, neurologic disorders and skin lumps. The cerebrospinal fluid may also contain the larvae.
  • Acquired angioedema: A rare disorder characterized by recurring episodes of swelling of parts of the skin or mucous membranes. Sometimes internal organs may be involved. The disorder occurs in patients with lymphoproliferative or autoimmune disorders which result in the dysfunction of a complex blood protein called C1 inhibitor.
  • Adverse reaction: Term to describe unwanted, negative consequences sometimes associated with using medications, diagnostic tests or therapeutic interventions.
  • Allergic conjunctivitis: also known as vernal catarrah
  • Ancylostoma duodenale: An infestation with Ancylostoma duodenale which is a parasitic hookwork whichcan cause serious disease in humans - usually occurs in people who work barefoot in damp soil. The hookworms suck blood from the intestines of the host which can result in anemia if there is a large number of worms.
  • Athlete's foot: A condition which is characterized by a chronic superificial infection of the foot caused by a fungi
  • Atopic dermatitis: Skin rash usually from allergic causes.
  • Autosensitization dermatitis: A skin reaction involving the development of a variety of skin lesions in response to infections (virus, bacteria, fungus, parasite), inflammatory skin conditions or other triggers. The skin reaction may vary considerable in appearance from itchy red skin to the development of blisters and may involve variable portions of the body.
  • Bacterial conjunctivitis: Infection and inflammation of the conjunctiva caused by bacteria.
  • Benadryl -- Teratogenic Agent: There is evidence to indicate that exposure to Benadryl during pregnancy may have a teratogenic effect on the fetus. A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
  • Bile acid synthesis defect, congenital, 2: A defect which prevents the body from making bile acid which results in progressive liver disease. The defect is a deficiency of a particular enzyme (cholestasis with delta(4)-3-oxosteroid 5-beta-reductase) needed to make bile acid.
  • Bile acid synthesis defects: A defect which prevents the body from making bile acid which results in progressive liver disease.
  • Bile acid synthesis defects, congenital, 1: A defect which prevents the body from making bile acid which results in progressive liver disease. The defect is a deficiency of a particular enzyme (3-beta-hydroxy-delta-5-C27-steroid oxidoreductase) needed to make bile acid.
  • Bile acid synthesis defects, congenital, 2: A defect which prevents the body from making bile acid which results in progressive liver disease. The defect is a deficiency of a particular enzyme (cholestasis with delta(4)-3-oxosteroid 5-beta-reductase) needed to make bile acid.
  • Bile acid synthesis defects, congenital, 3: A defect which prevents the body from making bile acid which results in progressive liver disease. The defect involved a deficiency of 7-alpha-hydroxylase which is an enzyme needed to prevent the accumulation of 27-hydroxycholesterol which is toxic to the liver.
  • Bile acid synthesis defects, congenital, 4: A defect which prevents the body from making bile acid which results in progressive liver disease.
  • Blisters: Blistering of the skin.
  • Body symptoms: Symptoms affecting the entire body features.

A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
  • Cercarial dermatitis: A short-lived rash that occurs as an allergic reaction to larval (cercariae) infection of the skin. These particular parasites use birds and animals as their first hosts. Larval eggs are excreted in the faeces and when they land in water, they hatch into larvae which then infect certain aquatic snails. The infected snails release another form of the larvae called cercariae which then search for a bird, mammal host. When they enter the skin of a human they die as humans are unsuitable hosts but the skin can produce an allergic reaction.

A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
  • Cholestasis disease of pregnancy: A liver condition that can occur usually in the last stage of pregnancy. The flow of bile in the gallbladder or liver is impaired by the high levels of pregnancy hormones. The bile acids build up in the organs and then enter the bloodstream. The main symptom is usually itching. Symptoms usually resolve after delivering the baby. Risk factors includes existing liver condition, multiple pregnancy and a family history of the condition.
  • Cholestasis, progressive familial intrahepatic 1: A rare inherited condition where bile is unable to drain from the liver where it builds up and causes progressive liver damage.
  • Cholestasis, progressive familial intrahepatic 3: A rare inherited condition where bile is unable to drain from the liver where it builds up and causes progressive liver damage. The condition has an early onset and usually leads to end-stage liver disease by the end of the second decade. The various types of this condition differ in the origin of the genetic defect (liver-specific ATP-binding cassette transporter on chromosome 2q24). Type 2 is also associated with an increased risk of liver cancer in the first few years of life.
  • Chronic Kidney Disease: Long-term and generally irreversible disease of the kidneys due to infection, obstruction, congenital diseases or generalised diseases causing failure of the kidneys' normal functions.
