Karelitz and Stempien discovered that extracts from human serum globulin and placental globulin can be used as lightening agents for scarlet fever and this was used later as the basis for the Dick test. The association of scarlet fever and bacteriophages was described in 1926 by Cantacuzène (Ioan Cantacuzino) and Bonciu.An antitoxin for scarlet fever was developed in 1924. The first toxin which causes this disease was cloned and sequenced in 1986 by Weeks and Ferretti. The discovery of penicillin and its subsequent widespread use has significantly reduced the mortality of this once feared disease. Reports of cases of scarlet fever have been on the rise in countries including England, Wales, South Korea, Vietnam, China, and Hong Kong in recent years. Researchers are unsure as to what has caused the spike in cases of the disease. The Dick test
The Dick test, invented in 1924 by George F. Dick and Gladys Dick, was used to identify those susceptible to scarlet fever. The Dick test consisted of injecting a diluted strain of the streptococci known to cause scarlet fever into a persons skin. A local reaction in the skin at the site of injection appeared in people who were susceptible to developing scarlet fever. The reaction was most notable around 24 hours after the injection but could be seen as early as 4 hours. If no reaction was seen in the skin, then that person was assumed to have already developed immunity to the disease and was not at risk of developing it. References

The first USFDA NDA failed to gain approval and was followed by a pair of NDAs (one for alogliptin and a second for a combination of alogliptin and pioglitazone) in July 2011. In 2012, Takeda received a negative response from the USFDA on both of these NDAs, citing a need for additional data.In 2013, the FDA approved the drug in three formulations: as a stand-alone with the brand-name Nesina, combined with metformin using the name Kazano, and when combined with pioglitazone as Oseni.
