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. See the entire definition of Antibiotic

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.

Muscle which is responsible for moving extremities and external areas of the body is called "skeletal muscle." Heart muscle is called "cardiac muscle." Muscle that is in the walls of arteries and bowel is called "smooth muscle."
Oral cancer: Cancer within the mouth.
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 .

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. See the entire definition of Yeast infection
