Whooping cough eight weeks, or sometimes longer. A gradual transition then occurs to the convalescent stage, which usually lasts one to four weeks. This stage is marked by a decrease in paroxysms of coughing, although paroxysms may occur with subsequent respiratory infection for many months after the onset of pertussis.

Fabry disease his classic paper on his electron microscopic findings in Fabry disease in 1965. The first specific treatment for Fabry disease was approved in 2001. Fabry disease Fabry disease, also known as Anderson–Fabry disease, is a rare genetic disease that can affect many parts of the body including the kidneys, heart, and skin. Fabry disease is one of a group of conditions known as lysosomal storage diseases. The genetic mutation that causes Fabry disease interferes with the function of an enzyme which processes biomolecules known as sphingolipids, leading to these substances building up in the walls of blood vessels and other
