Candidiasis (Yeast Infection, Candida) Glossary of Terms
The following are health and medical definitions of terms that appear in the Candidiasis (Yeast Infection, Candida) article.
Abdomen: The belly, that part of the body that contains all of the structures between the chest and the pelvis. The abdomen is separated anatomically from the chest by the diaphragm, the powerful muscle spanning the body cavity below the lungs. Abdominal: Relating to the abdomen, the belly, that part of the body that contains all of the structures between the chest and the pelvis. The abdomen is separated anatomically from the chest by the diaphragm, the powerful muscle spanning the body cavity below the lungs. Abdominal pain: Pain in the belly (the abdomen). Abdominal pain can come from conditions affecting a variety of organs. The abdomen is an anatomical area that is bounded by the lower margin of the ribs above, the pelvic bone (pubic ramus) below, and the flanks on each side. Although abdominal pain can arise from the tissues of the abdominal wall that surround the abdominal cavity (the skin and abdominal wall muscles), the term abdominal pain generally is used to describe pain originating from organs within the abdominal cavity (from beneath the skin and muscles). These organs include the stomach, small intestine, colon, liver, gallbladder, and pancreas. Abnormal: Not normal. Deviating from the usual structure, position, condition, or behavior. In referring to a growth, abnormal may mean that it is cancerous or premalignant (likely to become cancer). Acute: Of abrupt onset, in reference to a disease. Acute often also connotes an illness that is of short duration, rapidly progressive, and in need of urgent care. Antibiotic: A drug used to treat infections caused by bacteria and other microorganisms. Originally, an antibiotic was a substance produced by one microorganism that selectively inhibits the growth of another. Synthetic antibiotics, usually chemically related to natural antibiotics, have since been produced that accomplish comparable tasks. Antifungal: A drug used to treat fungal infections. Antifungal agent: A drug used to treat fungal infections. Anus: The opening of the rectum to the outside of the body. Appendicitis: Inflammation of the appendix, the small worm-like projection from the first part of the colon. Appendicitis usually involves infection of the appendix by bacteria that invade it and infect the wall of the appendix. Appendicitis can progress to produce an abscess (a pocket of pus) and even peritonitis (inflammation of the lining of the abdomen and pelvis). Bacteria: Single-celled microorganisms which can exist either as independent (free-living) organisms or as parasites (dependent upon another organism for life). Bacterial: Of or pertaining to bacteria. For example, a bacterial lung infection. Bacterial vaginosis: A vaginal condition characterized by an abnormal vaginal discharge due to an overgrowth of normal bacteria in the vagina. Women with bacterial vaginosis have less of the normal vaginal bacteria called lactobacilli. Symptoms are the vaginal discharge and sometimes a fishy odor. A sign under the microscope is an unusual vaginal cell called a clue cell. A metanalysis of 18 separate studies involving over 20,000 women demonstrated that bacterial vaginosis predisposes to preterm pregnancy and the earlier a vaginal infection occurs in pregnancy, the greater is the risk of a preterm delivery. The metanalysis also revealed that bacterial vaginosis increases the risk of a spontaneous abortion nearly 10-fold. Bacterial vaginosis also can lead to infection of the amniotic fluid and of the uterus after delivery. Therefore, screening and treatment for bacterial vaginosis during pregnancy may be done. Treatment options for bacterial vaginosis include vaginal gels and oral antibiotics. The antibiotic treatment is the same in pregnancy as in non-pregnant women. Biopsy: The removal of a sample of tissue for purposes of diagnosis. (Many definitions of "biopsy" stipulate that the sample of tissue is removed for examination under a microscope. This may or may not be the case. The diagnosis may be achieved by other means such as by analysis of chromosomes or genes.) Birth control: Birth control is the use of any practices, methods, or devices to prevent pregnancy from occurring in a sexually active woman. Also referred to as family planning, pregnancy prevention, fertility control, or contraception; birth control methods are designed either to prevent fertilization of an egg or implantation of a fertilized egg in the uterus. Brain: That part of the central nervous system that is located within the cranium (skull). The brain functions as the primary receiver, organizer and distributor of information for the body. It has two (right and left) halves called "hemispheres." Breast bone: Familiar name for the sternum, the long flat bone in the middle of the front of the chest. Breastfeeding: Feeding a child human breast milk. According to the American Academy of Pediatrics, human breast milk is preferred for all infants. This includes even premature and sick babies, with rare exceptions. It is the food least likely to cause allergic reactions; it is inexpensive; it is readily available at any hour of the day or night; babies accept the taste readily; and the antibodies in breast milk can help a baby resist infections. Cancer: An abnormal growth of cells which tend to proliferate in an uncontrolled way and, in some cases, to metastasize (spread). Candida albicans: A yeast-like fungal organism found in small amounts in the normal human intestinal tract. Normally kept in check by the body's own helpful bacteria, C. albicans can increase in numbers when this balance is disturbed to cause candidiasis of the intestinal tract, or yeast infections of other parts of the body. C. albicans causes thrush. Also called Monilia albicans. Candidiasis: Overgrowth of the C. albicans yeast in the gastrointestinal tract, or infection of other body areas with this yeast. Vaginal yeast infections, some forms of diaper rash and other skin rashes that emerge in moist, warm areas of skin, and thrush (a condition characterized by patches of white inside the mouth and/or throat) are all forms of yeast infection. Candidiasis tends to develop when the normal balance of bacteria (flora) in the area is upset, as can occur with antibiotic use. Prevention measures include the use of probiotics and in some cases dietary changes. Treatment is via antifungal medications. Candidiasis is usually a minor and easily addressed problem, but can be more serious for those with immune-system disorders, such as AIDS. Catheter: A thin, flexible tube. For example, a catheter placed in a vein provides a pathway for giving drugs, nutrients, fluids, or blood products. Samples of blood can also be withdrawn through the catheter. Cell: The basic structural and functional unit in people and all living things. Each cell is a small container of chemicals and water wrapped in a membrane. Cheek: The side of the face forming the side wall of the mouth. Chemotherapy: 1. In the original sense, a chemical that binds to and specifically kills microbes or tumor cells. The term chemotherapy was coined in this regard by Paul Ehrlich (1854-1915). Chills: feelings of coldness accompanied by shivering. Chills may develop after exposure to a cold environment or may accompany a fever. Chlamydia: A type of bacteria one species of which causes an infection very similar to gonorrhea in the way that it is spread, the symptoms it produces, and the long-term consequences. CT scan: Computerized tomography scan. Pictures of structures within the body created by a computer that takes the data from multiple X-ray images and turns them into pictures on a screen. CT stands for computerized tomography. Cuts: Severed skin. Washing a cut or scrape with soap and water and keeping it clean and dry is all that is required to care for most wounds. Putting alcohol hydrogen peroxide, and iodine into a wound can delay healing and should be avoided. Seek medical care early if you think that you might need stitches. Any delay can increase the rate of wound infection. Any puncture wound through tennis shoes has a high risk of infection and should be seen by your healthcare professional. Any redness, swelling, increased pain, or pus draining from the wound may indicate an infection that requires professional care. Diabetes: Refers to diabetes mellitus or, less often, to diabetes insipidus. Diabetes mellitus and diabetes insipidus share the name "diabetes" because they are both conditions characterized by excessive urination (polyuria). Diagnosis: 1 The nature of a disease; the identification of an illness. 2 A conclusion or decision reached by diagnosis. The diagnosis is rabies. 3 The identification of any problem. The diagnosis was a plugged IV. Diaper rash: Also called "diaper dermatitis," a diaper rash is a skin inflammatory reaction localized to the area usually covered by the diaper. It can have many causes including infections (yeast, bacterial or viral), friction irritation, chemical allergies (perfumes, soaps), sweat and plugging of sweat glands. Discharge: 1.The flow of fluid from part of the body, such as from the nose or vagina. Douche: A stream of water directed at any part of the body or any body cavity, often into the vagina, for cleansing or medicinal purposes. Dysfunction: Difficult function or abnormal function. Esophagitis: Inflammation of the esophagus. The esophagus is that soft tube-like portion of the digestive tract connecting the pharynx with the stomach. Esophagus: The tube that connects the pharynx (throat) with the stomach. The esophagus lies between the trachea (windpipe) and the spine. It passes down the neck, pierces the diaphragm just to the left of the midline, and joins the cardiac (upper) end of the stomach. In an adult, the esophagus is about 25 centimeters (10 inches) long. When a person swallows, the muscular walls of the esophagus contract to push food down into the stomach. Glands in the lining of the esophagus produce mucus, which keeps the passageway moist and facilitates swallowing. Also known as the gullet or swallowing tube. From the Greek oisophagos, from oisein meaning to bear or carry + phagein, to eat. Fever: Although a fever technically is any body temperature above the normal of 98.6 degrees F. (37 degrees C.), in practice a person is usually not considered to have a significant fever until the temperature is above 100.4 degrees F (38 degrees C.). Fingernail: A fingernail is produced by living skin cells in the finger. A fingernail consists of several parts including the nail plate (the visible part of the nail), the nail bed (the skin beneath the nail plate), the cuticle (the tissue that overlaps the plate and rims the base of the nail), the nail folds (the skin folds that frame and support the nail on three sides), the lunula (the whitish half-moon at the base of the nail) and the matrix (the hidden part of the nail unit under the cuticle). Fungal: Pertaining to a fungus. For example, a fungal skin infection. Fungi: Plural of fungus. Fungus: A single-celled or multicellular organism. Fungi can be true pathogens (such as histoplasmosis and coccidioidomycosis) that cause infections in healthy persons or they can be opportunistic pathogens (such as aspergillosis, candidiasis, and cryptococcosis) that cause infections in immunocompromised persons (including cancer patients, transplant recipients, and persons with AIDS). An example of a common fungus is the yeast organism which causes thrush and diaper rash (diaper dermatitis). Fungi are also used for the development of antibiotics, antitoxins, and other drugs used to control various human diseases. Gastrointestinal: Adjective referring collectively to the stomach and small and large intestines. Genital: Pertaining to the external and internal organs of reproduction. (Not to be confused with genetic.) Gonorrhea: A sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoea. Although gonorrhea is known primarily as a sexually transmitted infection (STI), it is not exclusively so, but can also be transmitted to the newborn during the birthing process. Heart: The muscle that pumps blood received from veins into arteries throughout the body. It is positioned in the chest behind the sternum (breastbone; in front of the trachea, esophagus, and aorta; and above the diaphragm muscle that separates the chest and abdominal cavities. The normal heart is about the size of a closed fist, and weighs about 10.5 ounces. It is cone-shaped, with the point of the cone pointing down to the left. Two-thirds of the heart lies in the left side of the chest with the balance in the right chest. Hygiene: The science of preventive medicine and the preservation of health. From the name of Hygeia, the daughter of Asklepios, the Greek god of medicine (whose staff with entwined snake is the symbol of medicine). Asklepios (known to the Romans as Aesculapius) had a number of children including not only Hygeia but also Panaceia, the patroness of clinical medicine. Hygeia also followed her father into medicine. As the patroness of health, Hygeia was charged with providing a healthy environment to prevent illness. In Greek, "hygieia" means health. Immune: Protected against infection. The Latin immunis means free, exempt. Immune system: A complex system that is responsible for distinguishing us from everything foreign to us, and for protecting us against infections and foreign substances. The immune system works to seek and kill invaders. Indicate: In medicine, to make a treatment or procedure advisable because of a particular condition or circumstance. For example, certain medications are indicated for the treatment of hypertension during pregnancy while others are contraindicated. Infection: The growth of a parasitic organism within the body. (A parasitic organism is one that lives on or in another organism and draws its nourishment therefrom.) A person with an infection has another organism (a "germ") growing within him, drawing its nourishment from the person. Inflammation: A basic way in which the body reacts to infection, irritation or other injury, the key feature being redness, warmth, swelling and pain. Inflammation is now recognized as a type of nonspecific immune response. Itching: An uncomfortable sensation in the skin that feels as if something is crawling on the skin or in the skin, and makes the person want to scratch the affected area. Kidney: One of a pair of organs located in the right and left side of the abdomen which clear "poisons" from the blood, regulate acid concentration and maintain water balance in the body by excreting urine. The kidneys are part of the urinary tract. The urine then passes through connecting tubes called "ureters" into the bladder. The bladder stores the urine until it is released during urination. See the entire definition of Kidney Laboratory: A place for doing tests and research procedures and preparing chemicals, etc. Although "laboratory" looks very like the Latin "laboratorium" (a place to labor, a work place), the word "laboratory" came from the Latin "elaborare" (to work out, as a problem, and with great pains), as evidenced by the Old English spelling "elaboratory" designating "a place where learned effort was applied to the solution of scientific problems." Leukemia: Cancer of the blood cells. The growth and development of the blood cells are abnormal. Strictly speaking, leukemia should refer only to cancer of the white blood cells (the leukocytes) but in practice it can apply to malignancy of any cellular element in the blood or bone marrow, as in red cell leukemia (erythroleukemia). Liver: An organ in the upper abdomen that aids in digestion and removes waste products and worn-out cells from the blood. The liver is the largest solid organ in the body. The liver weighs about three and a half pounds (1.6 kilograms). It measures about 8 inches (20 cm) horizontally (across) and 6.5 inches (17 cm) vertically (down) and is 4.5 inches (12 cm) thick. See the entire definition of Liver Lungs: The lungs are a pair of breathing organs located with the chest which remove carbon dioxide from and bring oxygen to the blood. There is a right and left lung. Malaise: A vague feeling of discomfort, one that cannot be pinned down but is often sensed as "just not right." Menopause: The time in a woman's life when menstrual periods permanently stop; it is also called the "change of life." Menopause is the opposite of the menarche. Menstruation: The periodic blood that flows as a discharge from the uterus. Also called menorrhea, the time during which menstruation occurs is referred to as menses. The menses occurs at approximately 4 week intervals to compose the menstrual cycle. Microscope: An optical instrument that augments the power of the eye to see small objects. The name microscope was coined by Johannes Faber (1574-1629) who in 1628 borrowed from the Greek to combined micro-, small with skopein, to view. Although the first microscopes were simple microscopes, most (if not all) optical microscopes today are compound microscopes. Monilia: A yeast-like fungus now called Candida. Mouth: 1. The upper opening of the digestive tract, beginning with the lips and containing the teeth, gums, and tongue. Foodstuffs are broken down mechanically in the mouth by chewing and saliva is added as a lubricant. Saliva contains amylase, an enzyme that digests starch. 2. Any opening or aperture in the body. The mouth in both senses of the word is also called the os, the Latin word for an opening, or mouth. The o in os is pronounced as in hope. The genitive form of os is oris from which comes the word oral. MRI: Abbreviation and nickname for magnetic resonance imaging. For more information, see: Magnetic Resonance Imaging; Paul C. Lauterbur; Peter Mansfield. Mucous: Pertaining to mucus, a thick fluid produced by the lining of some tissues of the body. Nausea: Nausea, is the urge to vomit. It can be brought by many causes including, systemic illnesses, such as influenza, medications, pain, and inner ear disease. When nausea and/or vomiting are persistent, or when they are accompanied by other severe symptoms such as abdominal pain, jaundice, fever, or bleeding, a physician should be consulted. Oral candidiasis: Yeast infection of the mouth and throat caused by the fungus Candida albicans; also known as thrush. Yeast organisms are part of the germs normally found in various parts of the body. They ordinarily do not cause any symptoms. Organ: A relatively independent part of the body that carries out one or more special functions. The organs of the human body include the eye, ear, heart, lungs, and liver. Pain: An unpleasant sensation that can range from mild, localized discomfort to agony. Pain has both physical and emotional components. The physical part of pain results from nerve stimulation. Pain may be contained to a discrete area, as in an injury, or it can be more diffuse, as in disorders like fibromyalgia. Pain is mediated by specific nerve fibers that carry the pain impulses to the brain where their conscious appreciation may be modified by many factors. Palate: The roof of the mouth. The front portion is bony (hard palate), and the back portion is muscular (soft palate). Pelvic: Having to do with the pelvis, the lower part of the abdomen, located between the hip bones. Penis: The external male sex organ used to copulate and ejaculate semen and to convey urine outside the body. Potassium: The major positive ion (cation) found inside of cells. The chemical notation for potassium is K+. Pregnancy: The state of carrying a developing embryo or fetus within the female body. This condition can be indicated by positive results on an over-the-counter urine test, and confirmed through a blood test, ultrasound, detection of fetal heartbeat, or an X-ray. Pregnancy lasts for about nine months, measured from the date of the woman's last menstrual period (LMP). It is conventionally divided into three trimesters, each roughly three months long. Pregnant: The state of carrying a developing fetus within the body. Prescription: A physician's order for the preparation and administration of a drug or device for a patient. A prescription has several parts. They include the superscription or heading with the symbol "R" or "Rx", which stands for the word recipe (meaning, in Latin, to take); the inscription, which contains the names and quantities of the ingredients; the subscription or directions for compounding the drug; and the signature which is often preceded by the sign "s" standing for signa (Latin for mark), giving the directions to be marked on the container. Rash: Breaking out (eruption) of the skin. Medically, a rash is referred to as an exanthem. Recur: To occur again. To return. Any symptom (such as fatigue), any sign (such as a heart murmur), or any disease can recur. Recurrent: Back again. A recurrent fever is a fever that has returned after an intermission: a recrudescent fever. Rule out: A term much used in medicine, meaning to eliminate or exclude something from consideration. The ACB (albumin cobalt binding) test helps rule out a heart attack in the differential diagnosis of severe chest pain. Scan: As a noun, the data or image obtained from the examination of organs or regions of the body by gathering information with a sensing device. Speculum: An instrument used to widen an opening to look within a passage or a cavity. For example, a speculum may be used to widen the opening of the vagina so that the cervix is more easily visible. Other examples include the nasal speculum to look up into the nostrils and the ear speculum to look within the ear canal at the ear drum. The term "speculum" is the Latin word for mirror. Sperm: A sperm is the male "gamete" or sex cell. It combines with the female "gamete," called an ovum, to form a zygote. The formation process is called "fertilization." (see ovum, zygote). Spleen: An organ located in the upper left part of the abdomen near the stomach. The spleen produces lymphocytes; it is the largest lymphatic organ in the body. The spleen also filters the blood, serves as a major reservoir for blood and destroys blood cells that are aged. Sternum: Anatomic name for the breast bone, the long flat bone in the upper middle of the front of the chest. Steroid: A general class of chemical substances that are structurally related to one another and share the same chemical skeleton (a tetracyclic cyclopenta[a]phenanthrene skeleton). Stomach: 1. The sac-shaped digestive organ that is located in the upper abdomen, under the ribs. The upper part of the stomach connects to the esophagus, and the lower part leads into the small intestine. Superficial: In anatomy, on the surface or shallow. As opposed to deep. The skin is superficial to the muscles. The cornea is on the superficial surface of the eye. Swallowing tube: Descriptive term for the esophagus. See: Esophagus. 
Symptom: Any subjective evidence of disease. Anxiety, lower back pain, and fatigue are all symptoms. They are sensations only the patient can perceive. In contrast, a sign is objective evidence of disease. A bloody nose is a sign. It is evident to the patient, doctor, nurse and other observers. Systemic: Affecting the entire body. A systemic disease such as diabetes can affect the whole body. Systemic chemotherapy employs drugs that travel through the bloodstream and reach and affect cells all over the body. Therapy: The treatment of disease. Thrush: Yeast infection of the mouth and throat, characterized by patches of white, caused by the fungus Candida albicans . Tongue: The tongue is a strong muscle anchored to the floor of the mouth. It is covered by the lingual membrane which has special areas to detect tastes. Trichomoniasis: Infection with trichomonas, in humans with Trichomonas vaginalis. Troche: A small medicated lozenge designed to dissolve. For example, to soothe the throat as a cough drop. Urinary: Having to do with the kidneys, ureters, and bladder. The urinary system represents the functional and anatomic aspects of the kidneys, ureters, and bladder. Urine: Liquid waste. The urine is a clear, transparent fluid. It normally has an amber color. The average amount of urine excreted in 24 hours is from 40 to 60 ounces (about 1,200 cubic centimeters). Chemically, the urine is mainly an aqueous (watery) solution of salt (sodium chloride) and substances called urea and uric acid. Normally, it contains about 960 parts of water to 40 parts of solid matter. Abnormally, it may contain sugar (in diabetes), albumen (a protein) (as in some forms of kidney disease), bile pigments (as in jaundice), or abnormal quantities of one or another of its normal components. Uterus: The uterus (womb) is a hollow, pear-shaped organ located in a woman's lower abdomen between the bladder and the rectum. The narrow, lower portion of the uterus is the cervix; the broader, upper part is the corpus. The corpus is made up of two layers of tissue. See the entire definition of Uterus Vagina: The muscular canal extending from the cervix to the outside of the body. It is usually six to seven inches in length, and its walls are lined with mucus membrane. It includes two vaultlike structures, the anterior (front) vaginal fornix and the posterior (rear) vaginal fornix. The cervix protrudes slightly into the vagina, and it is through a tiny hole in the cervix (the os) that sperm make their way toward the internal reproductive organs. The vagina also includes numerous tiny glands that make vaginal secretions. Vaginal discharge: Vaginal discharge is a fluid produced by glands in the vaginal wall and cervix that drains from the opening of the vagina. The amount and appearance of normal vaginal discharge varies throughout the menstrual cycle. An increase in the amount of vaginal discharge, an abnormal odor or consistency of the fluid, or pain that accompanies vaginal discharge can all be signs of infection or other disorders. Such disorders include (this is not an all inclusive list) bacterial vaginosis, yeast vaginitis, and vaginitis. Vaginal yeast infection: Infection of the vagina caused by a fungus known as Candida. A yeast vaginal infection is characterized by itching, burning, soreness, pain during intercourse and/or urination, and vaginal discharge that is typically cheesy white in color. The diagnosis is confirmed through identification of the yeast under a microscope from a specimen scraped from the vaginal area. A yeast vaginal infection that is causing symptoms is treated with topical medications applied in and around the vagina and with medications taken by mouth. Topical antibiotic creams include butoconazole (Femstat 3), clotrimazole (Lotrimin), miconazole (Monistat), and terconazole (Terazol 3). Clotrimazole, miconazole, terconazole, and nystatin (Mycostatin) are also available as vaginal tablets. Oral antibiotics for yeast vaginitis include fluconazole (Diflucan). During pregnancy, only the topical creams are used. Vaginitis: Inflammation of the vagina. The vagina is the muscular canal extending from the cervix to the outside of the body. Vaginitis is often caused by a fungus. A woman with this condition may have itching or burning and may notice a discharge. Vaginitis is a common condition. There are factors that predispose a woman to develop vaginitis. For example, women who have diabetes have vaginitis more often than women who do not. Yeast infection: Overgrowth of yeast can affect the skin (yeast rash), mouth (thrush), digestive tract, esophagus, vagina (vaginitis), and other parts of the body. Yeast infections occur most frequently in moist areas of the body. Although Candida albicans and other Candida yeasts are the most frequent offenders, other yeast groups are known to cause illness, primarily in immunocompromised patients. These include Torulopsis, Cryptococcus, Malassezia, and Trichosporon yeasts. Diagnosis is by observation, and can be confirmed by culturing a stool or mucosa sample, or a scraping from the affected area. Treatment is by topical or oral antifungal medications. Acidophilous, a helpful bacteria that normally helps to keep yeast in check, can also be tried in supplement form or in yogurt with live cultures. |

Candidiasis (Yeast Infection, Candida)
Oral Thrush Overview
Thrush (formally "oropharyngeal candidiasis") is a superficial yeast infection that may involve the tongue, inner cheek (buccal mucosa), inner lip region, and occasionally the gums (gingiva). While it is most commonly seen in young infants, thrush may affect toddlers, and to a lesser degree, older children and occasionally adults. Oral thrush diagnosed in an adult should always lead to a search for an underlying medical condition (diabetes, use of immunosuppressive therapy, etc.).
Oral Thrush Causes
Thrush is caused by an overgrowth of the yeast Candida albicans, which is commonly found on skin surfaces, the oral cavity, and throughout the intestinal tract of healthy individuals. Newborn infants often are exposed during delivery and may develop oral evidence of thrush within 10 days post-delivery. Breastfeeding infants may infect their mother's nipple area during breastfeeding. In additio...
