DTP was licensed in 1949. DTaP and Tdap are both combined vaccines against diphtheria, tetanus, and pertussis. The difference is in the dosage, with the upper case letters meaning higher quantity. DTaP (also DTPa and TDaP) is a combined vaccine against diphtheria, tetanus, and pertussis, in which the pertussis component is acellular.

Fatty liver disease Fatty liver disease Fatty liver disease (FLD), also known as hepatic steatosis, is a condition where excess fat builds up in the liver. There are two types non-alcoholic fatty liver disease (NAFLD) and alcoholic liver disease. NAFLD is made up of simple fatty liver and non-alcoholic steatohepatitis (NASH). Risk factors for NAFLD include diabetes, obesity, and older age. The condition is also associated with other diseases that influence fat metabolism. It is difficult to distinguish alcoholic FLD, which is part of alcoholic liver disease, from nonalcoholic FLD (NAFLD), and both show microvesicular and macrovesicular fatty changes at different stages.
