A sudden, sometimes fatal, disease of the brain (encephalopathy) with degeneration of the liver, occurs in children (most cases 4-12 years of age), comes after the chickenpox (varicella) or an influenza-type illness, is also associated with taking medications containing aspirin.

Radio frequency identification, a system for remotely storing and retrieving data. RFID tags can serve to identify and track medications.
Restriction fragment length polymorphism. A difference in DNA between people that can be recognized by the use of a restriction enzyme.
- Rh factor
An antigen found on the surface of red blood cells. Red blood cells with the antigen are said to be Rh positive (Rh+). Those without the surface antigen are said to be Rh negative (Rh-). Blood used in transfusions much match donors for Rh status as well as for ABO blood group, as Rh- patients […]

the first twin was hydropic (swollen with edema fluid) and stillborn, and the second of the twins was deeply jaundiced and subsequently died of kernicterus.
A condition in which skeletal muscle is broken down, releasing muscle enzymes and electrolytes from inside the muscle cells. Risks of rhabdomyolysis include muscle breakdown and kidney failure because the cellular component myo- globin is toxic to the kidneys. Rhabdomyolysis is relatively uncommon, but it most often occurs as the result of extensive muscle damage […]
