Xofigo Approved for Prostate Cancer THURSDAY, May 16 (HealthDay News) -- The U.S. Food and Drug Administration has approved a drug to help men with advanced prostate cancer whose disease has spread to the bones. The drug, Xofigo, is targeted to patients with late-stage, metastatic disease that has spread to the bones but not to other organs, the FDA said in a news release. It is meant for patients who have already undergone surgery and/or drug therapies such as hormone-based treatments. In a clinical tr...

X-rays of the Extremities (X-ray of the Arm, Leg, Hand, Wrist, Foot, Ankle, Shoulder, Knee, or Hip) Procedure overview What are X-rays of the extremities? X-rays use invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs on film. Standard X-rays are performed for many reasons, including diagnosing tumors or bone injuries. X-rays are made by using external radiation to produce images of the body, its organs, and other internal structures for diagnostic purposes. X...

X-rays of the Skull (Skull X-ray Studies) Procedure overview What are X-rays of the skull? X-rays use invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs on film. Standard X-rays are performed for many reasons, including diagnosing tumors or bone injuries. X-rays are made by using external radiation to produce images of the body, its organs, and other internal structures for diagnostic purposes. X-rays pass through body tissues onto specially treated plates (s...

X-rays of the Spine, Neck, or Back (Cervical, Thoracic, Lumbar, Sacral, or Coccygeal X-ray Studies) Procedure overview What are X-rays of the spine, neck, or back? X-rays use invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs on film. Standard X-rays are performed for many reasons, including diagnosing tumors or bone injuries. X-rays are made by using external radiation to produce images of the body, its organs, and other internal structures for diagnostic pu...

X-linked Dominant: Incontinentia Pigmenti Genes are inherited from our biological parents in specific ways. One of the basic patterns of inheritance of our genes is called X-linked dominant inheritance. What is X-linked dominant inheritance? X-linked dominant inheritance occurs when the gene is located on the X chromosome, but the gene acts in a dominant manner. This means that both males and females can display the trait or disorder, when they only have one copy of the gene. Click Image to Enlarge Depe...

X-linked Recessive: Red-Green Color Blindness, Hemophilia A Genes are inherited from our biological parents in specific ways. One of the basic patterns of inheritance of our genes is called X-linked recessive inheritance. What is X-linked inheritance? X-linked inheritance means that the gene causing the trait or the disorder is located on the X chromosome. Remember, females have two X chromosomes, while males have one X and one Y. Genes on the X chromosome can be recessive or dominant, and their express...

X-linked Agammaglobulinemia What is X-linked agammaglobulinemia? X-linked agammaglobulinemia, also called Bruton's agammaglobulinemia or congenital agammaglobulinemia, was the first immunodeficiency disease ever identified. "X-linked" means that the gene which causes this agammaglobulinemia is located on the X chromosome, and therefore primarily affects males because it is unlikely that females will have two altered copies of the gene. The disease causes the child to be unable to produce antibodies that...

X-Rays What are X-rays? X-rays use invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs on film or digital media. Standard X-rays are performed for many reasons, including diagnosing tumors or bone injuries. X-rays are made by using external radiation to produce images of the body, its organs, and other internal structures for diagnostic purposes. X-rays pass through body structures onto specially-treated plates (similar to camera film) or digital media and a "...

Xeljanz Approved for Rheumatoid Arthritis WEDNESDAY, Nov. 7 (HealthDay News) -- Xeljanz (tofacitinib) has been approved by the U.S. Food and Drug Administration to treat symptoms of rheumatoid arthritis (RA) among people who can't tolerate, or haven't been helped by, the drug methotrexate. RA is an autoimmune disease in which the immune system mistakenly attacks the body. In the case of RA, this leads to swelling of the joints and nearby tissues. About 1.5 million Americans have RA, the FDA said in a ne...
