Forces Institute of Pathology during World War II. In 1952, she became the chief of pathology at Babies Hospital. Later that year, Dorothy Hansine Andersen was awarded the Elizabeth Blackwell Award. Research career During her research career, Dorothy Hansine Andersen studied many children who had digestive or breathing problems, performing autopsies on those who died from these problems. While performing the autopsies she noticed many of the patients who had died from celiac disease had fluid-filled cysts that were surrounded by scars on the pancreas. She also found similar scars and tissue damage in the lungs. These factors led her to the conclusion that the lung and pancreas damage came from the same disease that she called "cystic fibrosis of the pancreas". The name cystic describes to the cysts found the fibrosis describes the scar tissue in the lungs and pancreas. Her research was published in the American Journal of Diseases of Children in 1938. She was awarded the E. Mead Johnson Award in 1939 for her recognition of this disease. In 1942 at Babies Hospital, Andersen developed the first efficient diagnostic test for cystic fibrosis with Paul di Sant'Agnese, who also worked at Columbia University. In 1948, The American Academy of Pediatrics awarded the Borden Bronze Plaque to Anderson for her successful research in nutrition that was entitled “Determining the effectiveness of different antibiotics in relieving the respiratory-tract infections that were the main cause of death from cystic fibrosis.” By 1958, Andersen was a full-time professor at the Columbia College of Physicians and Surgeons. During this time in her career, Andersen wrote in the Journal of Chronic Diseases that her research findings corresponded to cystic fibrosis, a recessively inherited disease that had been thought to be fatal in early infancy, however, she now found that many patients were surviving until early adulthood. Andersen published her final paper in 1959 on the reoccurrence of cystic fibrosis in young adults. Researchers could not determine the cause of cystic fibrosis until the early 1980s, At that time it was confirmed that a single mutation was the cause of the incomplete synthesis of a transmembrane protein that results in thick, clogging secretions mainly in the pancreas and respiratory tract. In addition to her research on cystic fibrosis, Dorothy Hansine Andersen also initially investigated and described a rare glycogen storage disease, glycogen storage disease type IV (GSD IV) also known as Andersen's disease.
