Like a drink of water, blood is something we take for granted. But when a problem arises, we suddenly realize its undisputed value. Blood, the precious fluid that makes up about 7 percent of the body's weight and comprises some two gallons in the average adult, carries oxygen and nutrients to all parts of the body. It ferries carbon dioxide and other waste products back to the lungs, kidneys and liver for disposal. It fights infection and helps heal wounds. Composed of a mixture of cells and watery liquid called plasma that the cells float in, blood is made in the bone marrow, a jelly-like substance inside the bone. Disorders of the blood are usually managed by a specialist called a hematologist. Such disorders can be found in people of all ages and may also be related to any number of factors, including genetics, environmental exposures, diet and infections. Clearly a very complex specialty, here at Johns Hopkins hematology is divided into adult and pediatric divisions. Robert Brodsky, MD, heads Adult Hematology, while James Casella, MD, heads Pediatric Hematology. Each division offers the full range of diagnostic services as well as access to Johns Hopkins specialists in related disciplines. The divisions are renowned in their ability to characterize unusual blood disorders and are at the cutting edge of developing and refining new treatments. Considerable ongoing research supports these efforts. While most patients seen by a hematologist at Johns Hopkins are referred by another physician, those who want a second opinion or different treatment options are welcome to call on their own.
