Contact healing
Another name for the alternative medicine practice of laying on of hands.

Content validity
The extent to which a variable (for example, a rating scale) measures what it is supposed to measure (for example, self-care ability).
Contig
Contiguous sequence of DNA created by assembling overlapping sequenced fragments of a chromosome. A group of clones representing overlapping regions of the genome.
Contig map
A map depicting the relative order of a linked library of small overlapping clones representing a complete chromosome segment.
Contiguous gene syndrome
A disorder due to deletion of multiple gene loci that are adjacent to one another. Contiguous gene syndromes are characterized by multiple, apparently unrelated, clinical features caused by deletion of the multiple adjacent genes. Each of the individual genes within a contiguous region, when mutated, gives rise to a distinct feature.
Continence
The ability to hold in a bowel movement or urine.
Continent ileostomy

A machine used to help rehabilitate a limb (an arm or leg).
Contra Costa Regional Medical Center
The Contra Costa Regional Medical Center is a hospital in Contra Costa, California, United States.
Contraception
The intentional prevention of conception or impregnation. Also called birth control.
Contraceptive device, intrauterine (IUD)
A device inserted into the uterus (womb) to prevent conception (pregnancy). The IUD can be a coil, loop, triangle, or T in shape made of plastic or metal.
Contraceptive sponge, vaginal
A contraceptive device that is donut-shaped, made of plastic, contains a spermicide (nonoxynol-9) and is inserted into the vagina to cover the cervix. A loop is provided to ease removal.
Contraceptive, combined oral
"Commonly called ""the pill,"" combined oral contraceptives are the most commonly used form of reversible birth control in the United States. This form of birth control suppresses ovulation (the monthly release of an egg from the ovaries) by the combined actions of the hormones estrogen and progestin."
Contraceptive, diaphragm
A barrier method of contraception that is available by prescription only and must be sized by a health professional to achieve a proper fit.
Contraceptive, minipill
"A form of oral contraceptive taken daily, like combined oral contraceptives (the ""pill""), but containing only the hormone progestin and no estrogen. "
Contraceptive, pill
"Commonly called ""the pill,"" combined oral contraceptives are the most commonly used form of reversible birth control. This form of birth control suppresses ovulation (the monthly release of an egg from the ovaries) by the combined actions of the hormones estrogen and progestin."
Contract
A written, dated, and signed agreement between two or more involved parties that sets out any arrangements on delegation and distribution of tasks and obligations and, if appropriate, on financial matters. The protocol may serve as the basis of a contract.
Contraction
During labor, the strong, rhythmic tightening of the uterus. Pre-laborcontractions are usually irregular and don't increase in intensity orduration.
Contraction, uterine
"The tightening and shortening of the uterine muscles. During labor, contractions accomplish two things: (1) they cause the cervix to thin and dilate (open); and (2) they aid the baby to descend into the birth canal."
Contractions, Braxton Hicks
Irregular contractions of the womb (the uterus) occurring towards the middle of pregnancy in the first pregnancy and, earlier and more intensely, in subsequent pregnancies.
Contracture
Deformity caused by abnormal shortening of the muscles.
Contraindicate
To make a treatment or procedure inadvisable because of a particular condition or circumstance. For examples, certain medications are contraindicated during pregnancy because of the danger they pose to the fetus and the use of aspirin is clearly contraindicated in small children because of the danger of Reye syndrome.
Contraindication
A condition that makes a treatment not helpful or even harmful.
Contralateral
Affecting or pertaining to the opposite side.
Contrast
"Short for ""contrast media."" Contrast media are X-ray dyes used to provide contrast, for example, between blood vessels and other tissue."
Contrast media
"X-ray dye. Commonly spoken of as ""contrast."""
Contrast medium
A substance used in x-ray studies to aid in showing internal structures.
Contrast nephropathy
A form of acute renal failure that starts soon after administration of contrast media (dye) for X-rays. The disorder usually runs a benign course and only rarely requires recourse to dialysis.
Contrast sensitivity function
The reciprocal of the threshold contrast required to obtain a criterion response from a cell or a human subject as a function of spatial frequency. Falls off in sensitivity as the spatial frequency of the test pattern increases.
Contrast sensitivity, visual
The ability to perceive differences between an object and its background.
Control (genetic)
The control of gene expression. Genetic control may be on the transcriptional or translational level. Transcriptional control works by controlling the number of RNA transcripts of a region of DNA, indirectly controlling protein synthesis. Translational control of protein synthesis works by regulating the step of translating RNA into protein.
Control (research)
In research, control subjects or control procedures permit comparison with experimental results.
Control group
The group of subjects in a controlled study that receives no treatment, a standard treatment, or a placebo instead of the therapy being investigated.
Controllable disease
disease or illness that can't be cured but can be managed with diet, exercise, or medications.
Controlled Disease
Taking care of oneself so that a disease has less of an effect on the body. People with diabetes can "control" the disease by staying on their diets, by exercising, by taking medicine if it is needed, and by monitoring their blood glucose. This care will help keep the glucose (sugar) level in the blood from becoming either too high or too low.
Controlled study
A study in which a test treatment is compared with a treatment that has known effects. The control group may receive no treatment, standard treatment, or placebo.
Contusion
A bruise; an injury of soft tissues without breaking the overlying skin.
PREVIOUS AND NEXT TERMS--------------------------------------
Condensation
A psychological process, often present in dreams, in which two or more concepts are fused so that a single symbol represents the multiple components.
Confabulation
Fabrication of stories in response to questions about situations or events that are not recalled.
Confrontation
A communication that deliberately pressures or invites another to self-examine some aspect of behavior in which there is a discrepancy between self-reported and observed behavior.
Constricted affect
Affect type that represents mild reduction in the range and intensity of emotional expression.
Constructional apraxia
An acquired difficulty in drawing two-dimensional objects or forms, or in producing or copying three-dimensional arrangements of forms or shapes.
Contingency reinforcement
Conversion
A defense mechanism, operating unconsciously, by which intrapsychic conflicts that would otherwise give rise to anxiety are instead given symbolic external expression. The repressed ideas or impulses, and the psychological defenses against them, are converted into a variety of somatic symptoms. These may include such symptoms as paralysis, pain, or loss of sensory function.
Coping mechanisms
Ways of adjusting to environmental stress without altering one's goals or purposes; includes both conscious and unconscious mechanisms.
Coprophagia
Eating of filth or feces.
Counterphobia
Deliberately seeking out and exposing onself to, rather than avoiding, the object or situation that is consciously or unconsciously feared.
Countertransference
The therapist's emotional reactions to the patient that are based on the therapist's unconscious needs and conflicts, as distinguished from his or her conscious responses to the patient's behavior. Countertransference may interfere with the therapist's ability to understand the patient and may adversely affect the therapeutic technique. Currently, there is emphasis on the positive aspects of countertransference and its use as a guide to a more empathic understanding of the patient.
