Bullous
|
|
BullousCharacterized by blistering, such as in a second-degree burn.
RELATED TERMS--------------------------------------
Burn
Damage to the skin or other body parts caused by extreme heat, flame, contact with heated objects, or chemicals. Burn depth is generally categorized as first, second, or third degree. The treatment of burns depends on the depth, area, and location of the burn, as well as additional factors, such as material that may be burned onto or into the skin. Treatment options range from simply applying a cold pack to emergency treatment to skin grafts.
SIMILAR TERMS--------------------------------------
Bulla
A large blister appearing as a circumscribed area of separation of the epidermis from the subepidermal structure (subepidermal bulla) or as a circumscribed area of separation of epidermal cells (intraepidermal bulla) caused by the presence of serum, or occasionally by an injected substance.
Bullae
More than one bulla, a bulla being a blister more than 5 mm (about 3/16 inch) in diameter with thin walls that is full of fluid.
Bullous pemphigoid
A disease characterized by tense blisters on the skin. The condition is caused by antibodies that accumulate abnormally in a layer of the skin called the basement membrane. The antigen of this autoimmune disease is localized to the hemidesmosome. Most cases of the disease are in older people but the disease can affect younger people, even babies. Bullous pemphigoid can be chronic, mild and not affect the general health or it can be severe and compromise the health of the sufferer. The diagnosis can be confirmed by a skin biopsy showing the abnormal antibodies deposited in the skin layer. Treatment is with topical cortisone creams, but especially severe cases may sometimes require high doses of cortisone-like drugs (steroids) or immune suppression drugs, such as azathoprine (Imuran).
PREVIOUS AND NEXT TERMS--------------------------------------
Buffalo chest
A single chest cavity with no anatomic separation of the two hemithoraxes due, for example, to tension pneumothorax (air under pressure collapsing a lung). It is called buffalo chest because this anatomical peculiarity of the North American buffalo, or bison, helped the Indians of the Great Plains to kill them. A single Indian arrow to the chest frequently was enough to let air in to collapse both lungs and fell the breathless bison.
Bulbar
Pertaining to a bulb, in medicine any rounded mass of tissue (that is shaped somewhat like a crocus or tulip bulb).
Bulbar conjunctiva
That part of the conjunctiva, a clear membrane of the eye, which covers the outer surface of the eye.
Bulimia susceptibility gene
A gene that determines the susceptibility to developing bulimia, one disorder in the spectrum of eating disorders. There is now a substantial literature showing that bulimia is strongly familial and that the pronounced familial nature of bulimia is due largely to the additive effects of a number of genes. One bulimia susceptibility gene is known to be linked to chromosome 10p (the short arm of chromosome 10). Another susceptibility gene for bulimia may be on chromosome 14.
Bullae
More than one bulla, a bulla being a blister more than 5 mm (about 3/16 inch) in diameter with thin walls that is full of fluid.

Bummed out
Slang term for depression.
BUN
Blood urea nitrogen. A measure primarily of the urea level in blood. Urea is cleared by the kidney and diseases which compromises the function of the kidney will frequently lead to increased blood levels. The blood BUN level can also rise in patients who are dehydrated.
Buprenorphine
A prescription medication for people addicted to heroin or other opiates that acts by relieving the symptoms of opiate withdrawal such as agitation, nausea and insomnia. Buprenorphine is more weakly addictive and has a lower risk of overdose than methadone. The effects last for about three days.
Burkholderia cepacia
(B. cepacia, for short.) A group of bacteria found in soil and water that are often resistant to common antibiotics. B. cepacia poses little medical risk to healthy people. However, people who have certain health problems such as a weakened immune systems or chronic lung disease, particularly cystic fibrosis (CF), are more susceptible to infection with it. Transmission of B. cepacia has been reported from contaminated solutions and medical devices as well as contaminated over-the-counter nasal spray and contaminated mouthwash. B. cepacia can also be spread to susceptible persons by person-to-person contact, contact with contaminated surfaces, and exposure to B. cepacia in the environment. Careful attention to infection control procedures like hand hygiene can help reduce the risk of transmission of this organism. Decisions on the treatment of infections with B. cepacia are best made on a case-by-case basis. Usually it can be treated with drugs called Trimethoprim-sulfamethoxazole or Meropenem.
