Multiple myeloma is a cancer formed by malignant plasma cells. Normal plasma cells are found in the bone marrow and are an important part of the immune system. The immune system is made up of several types of cells that work together to fight infections and other diseases. Lymphocytes (lymph cells) are the main cell type of the immune system. The major types of lymphocytes are T cells and B cells.
A coma is a prolonged state of unconsciousness. During a coma, a person is unresponsive to his or her environment. The person is alive and looks like he or she is sleeping. However, unlike in a deep sleep, the person cannot be awakened by any stimulation, including pain.
Radiosurgery: Radiosurgery devices, such as the CyberKnife Robotic Radiosurgery System, offer patients a new option for the treatment of lung cancer. The CyberKnife® System is used to treat lung cancer patients who cannot tolerate surgery, have an inoperable tumor, or are seeking an alternative to surgery.
As a curious child, you might remember staring at an older relative's thick stockings at the blue, gnarled veins lying under the skin like bumpy snakes. Known as varicose veins, these blood vessels, which return blood from the legs to the heart, are actually a more superficial system. The real, working venous system for the legs lies deeper, says to Robert A. Weiss, MD, assistant professor of dermatology at the Johns Hopkins School of Medicine in Baltimore. This is good news, because it means that if the surface veins begin to clump up and bulge, they can be removed or destroyed without ruining circulation to the leg. The National Institutes of Health estimates that 60% of all men and women suffer from some form of vein disorder. A quarter of varicose vein sufferers are men, although Weiss notes that it is almost always women who seek help for spider veins.
The Glasgow Coma Scale (GCS) is the most common scoring system used to describe the level of consciousness in a person following a traumatic brain injury. Basically, it is used to help gauge the severity of an acute brain injury.
Simply put, there isn’t enough room for wisdom teeth because our jaws don’t grow to be big enough to have enough space for them to come in. Since there isn’t enough room for them to erupt properly, wisdom teeth tend to come in at an angle or they don’t fully emerge, which causes problems for the rest of the mouth. Third molars (the wisdom teeth) routinely damage the teeth right next door, called second molars. Dentists recommend removing wisdom teeth before they become a problem and to avoid a more complicated surgery. Read more at Ask the Dentist: https://askthedentist.com/wisdom-teeth-removal/
Electrical cardioversion is a procedure in which an electric current is used to reset the heart's rhythm back to its regular pattern (normal sinus rhythm). The low-voltage electric current enters the body through metal paddles or patches applied to the chest wall.
The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood.
