Compartment syndrome
|
|
Compartment syndromeA condition in which there is swelling and an increase in pressure within a limited space (a compartment) that presses on and compromises blood vessels, nerves, and/or tendons that run through that compartment. Hence, the function of tissue within that compartment is compromised. Compartment syndromes usually involve the leg but can also occur in the forearm, arm, thigh, shoulder, and buttock. Some of the causes of increased pressure in compartment syndromes are trauma (for example, a fracture), too-tight wound dressings or casts, hemorrhage (bleeding) into the compartment, or inflammation (carpal tunnel syndrome, for example).
RELATED TERMS--------------------------------------
Condition
The term "condition" has a number of biomedical meanings including the following: 1.An unhealthy state, such as in "this is a progressive condition." 2.A state of fitness, such as "getting into condition." 3.Something that is essential to the occurrence of something else; essentially a "precondition." 4.As a verb: to cause a change in something so that a response that was previously associated with a certain stimulus becomes associated with another stimulus; to condition a person, as in behavioral conditioning.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Tissue
Biological tissue is a group of cells that perform a similar function.The study of tissues is known as histology, or, in connection with disease, histopathology.The classical tools for studying the tissues are the wax block, the tissue stain, and the optical microscope, though developments in electron microscopy, immunofluorescence, and frozen sections have all added to the sum of knowledge in the last couple of decades.
Forearm
The portion of the upper limb from the elbow to the wrist. In popular usage, the arm extends from the shoulder to the hand. However, in medical terminology, the arm refers to the upper extremity extending from the shoulder only to the elbow. The arm is thus distinguished in medical usage from the forearm, which extends from the elbow to the wrist.The forearm has 2 bones: the radius and ulna.
Arm
"1. In popular usage, the appendage that extends from the shoulder to the hand. However, the medical definition refers to the upper extremity extending from the shoulder only to the elbow, excluding the forearm, which extends from the elbow to the wrist. The arm contains one bone: the humerus. 2. In a randomized clinical trial, any of the treatment groups. Most randomized trials have two ""arms,"" but some have three ""arms,"" or even more."
Shoulder
The ball-and-socket joint connecting the arm with the body.
Trauma
Injury caused by external force, chemical, temperature extremes, or poor tooth alignment.
Wound
A wound is a physical trauma where the skin is torn, cut or punctured. Exposed to air, there is not only a significant chance of death due to loss of blood, but increased chance of bacteria entering the wound or an infection.
Hemorrhage
A general term for loss of blood, often profuse, brought about by injury to the blood vessels or by a deficiency of certain necessary blood elements such as platelets.
Inflammation
A reaction to an injury to the body - by infection, chemicals or physical agents. The symptoms can be - depending on the location of the injury- redness, swelling, heat and pain. The purpose of the inflammation is to dilute and destroy the agent causing the inflammation. To do this, the immune system starts a cascade of actions that causes active cells to gather at the affected location. It is these cells and fluids that cause the redness, swelling, heat and pain.
Syndrome
A grouping of signs and symptoms, based on their frequent co-occurrence, that may suggest a common underlying pathogenesis, course, familial pattern, or treatment selection.
SIMILAR TERMS--------------------------------------

Complement receptor
A structure found on erythrocytes, lymphocytes, neutrophils, monocytes and macrophages that binds C3 fragments.
Complement system
A series of molecules that work together to perform many immune system functions. For example, the complement system helps to dissolve and remove immune complexes and to kill foreign cells.

Complete androgen insensitivity syndrome
A genetic disorder that makes XY fetuses insensitive (unresponsive) to androgens (male hormones). Instead, they are born looking externally like normal girls. Internally, there is a short blind-pouch vagina and no uterus, fallopian tubes or ovaries. There are testes in the abdomen or the inguinal canal. The complete androgen insensitivity syndrome is usually detected at puberty when a girl should but does not begin to menstruate. Many of the girls with the syndrome have no pubic or axillary (armpit) hair. They have luxuriant scalp hair without temporal (male-pattern) balding. They are sterile and cannot bear children. They are at high risk for osteoporosis and so should take estrogen replacement therapy.

The cell behaves non-linearly, responding to a drifting cosine grating with a uniform increase in activity with no sinusiodal modulcation (i.e. insensitive to phase). For a historical perspective see Simple Cells.
Complex partial seizure
A form of partial seizure during which the person loses awareness. The patient does not actually become unconscious, and he or she may carry out actions as complex as walking, talking, or driving.

Computer addiction
A disorder in which the individual turns to the Internet or plays computer games in an attempt to change moods, overcome anxiety, deal with depression, reduce isolation or loneliness, or distract themselves from overwhelming problems. The elderly, as well as children and adolescents, are particularly vulnerable because they may not realize the extent of their dependency. In many instances, individuals with computer addiction may seek help for another condition, such as depression, phobias or other addictions.
Computer Tomography Scan
A diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general x-rays.
Computerized axial tomography (CAT)
Cat scanning adds X-ray images with the aid of a computer to generate cross-sectional views anatomy. It can identify normal and abnormal structures and be used to guide procedures. CAT scanning is painless. Iodine-containing contrast material is sometimes used in CAT scanning. If you are having a CAT scan and are allergic to iodine or contrast materials, you should notify your physicians and radiology staff.
Computerized axial tomography scan
Pictures of structures within the body created by a computer that takes the data from multiple X-ray images and turns them in pictures. The CAT (computerized axial tomography) scan can reveal some soft-tissue and other structures that cannot be seen in conventional X-rays. Using the same dosage of radiation as that of an ordinary X-ray machine, an entire slice of the body can be made visible with about 100 times more clarity with the CAT scan.

Common hepatic duct

This can happen, for example, in sports such with baseballs, softballs, lacrosse balls, hockey pucks and a blow in boxing. The only effective treatment is cardiopulmonary resuscitation with defibrillation to reverse ventricular fibrillation. Commotio cordis ia also known as a ""concussion of the heart."""

Complete androgen insensitivity syndrome
A genetic disorder that makes XY fetuses insensitive (unresponsive) to androgens (male hormones). Instead, they are born looking externally like normal girls. Internally, there is a short blind-pouch vagina and no uterus, fallopian tubes or ovaries. There are testes in the abdomen or the inguinal canal. The complete androgen insensitivity syndrome is usually detected at puberty when a girl should but does not begin to menstruate. Many of the girls with the syndrome have no pubic or axillary (armpit) hair. They have luxuriant scalp hair without temporal (male-pattern) balding. They are sterile and cannot bear children. They are at high risk for osteoporosis and so should take estrogen replacement therapy.
