If it is not removed, tooth decay will begin. The acids in plaque damage the enamel covering your teeth. It also creates holes in the tooth called cavities. Cavities usually do not hurt, unless they grow very large and affect nerves or cause a tooth fracture.

A broken bone requires emergency medical care. Your child might have a broken (fractured) bone if he or she heard or felt a bone snap, has difficulty moving the injured part, or if the injured part moves in an unnatural way or is very painful to the touch. A sprain occurs when the ligaments, which hold bones together, are overstretched and partially torn. A strain is when a muscle or tendon is overstretched or torn. Sprains and strains generally cause swelling and pain, and there may be bruises around the injured area. Most sprains and strains, after proper medical evaluation, can be treated at home.

Nuclear medicine is a branch of medical imaging that uses small amounts of radioactive material to diagnose and determine the severity of or treat a variety of diseases, including many types of cancers, heart disease, gastrointestinal, endocrine, neurological disorders and other abnormalities within the body.

Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs. Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder. You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.

Keyhole surgery can be helpful for patients with brain, pituitary and skull base tumors. With cutting edge technology and a proven track record in keyhole and endonasal endoscopic approaches, we make surgery safer, less invasive and more effective.

Each year in the United States, about 400 children and teens younger than age 20 are diagnosed. Osteosarcoma is the third most common cancer in teens, after lymphomas and brain tumors. It is extremely rare in children before age 5.

The pituitary gland is often portrayed as the "master gland" of the body. Such praise is justified in the sense that the anterior and posterior pituitary secrete a battery of hormones that collectively influence all cells and affect virtually all physiologic processes. The pituitary gland may be king, but the power behind the throne is clearly the hypothalamus. As alluded to in the last section, some of the neurons within the hypothalamus - neurosecretory neurons - secrete hormones that strictly control secretion of hormones from the anterior pituitary. The hypothalamic hormones are referred to as releasing hormones and inhibiting hormones, reflecting their influence on anterior pituitary hormones.

Anemia is a medical condition in which the red blood cell count or hemoglobin is less than normal. The normal level of hemoglobin is generally different in males and females. For men, a normal hemoglobin level is typically defined as a level of more than 13.5 gram/100 ml, and in women as hemoglobin of more than 12.0 gram/100 ml. These definitions may vary slightly depending on the source and the laboratory reference used. Continue Reading

St. John's wort (Hypericum perforatum) is an over-the-counter herbal supplement used for its antidepressant, anti-inflammatory, and wound-healing properties. Although it has been prescribed in Europe for mild to moderate depression, negative clinical trials and multiple reports of adverse drug interactions have raised concern about its use. St. John's wort induces various P450 isozymes (CYP 1A2, 2C19, 2C9, and 3A4) and P-glycoprotein systems. Drug interactions with the herbal product can lead to treatment failures with many medications, including hormonal contraceptives, antiretrovirals, immunosuppressive agents, narcotics, anticoagulants, and antifungals. There is also a risk for serotonin syndrome when St. John's wort is used in combination with other serotonergic antidepressants. The lack of strict regulation of herbal products that results in variable quality and content (unknown toxic ingredients or inactive ingredients) is also a concern.
