川崎病
A question was raised whether the disease only started during the period between 1960 and 1970, but later a preserved heart of a seven-year-old boy who died in 1870 was examined and showed three aneurysms of the coronary arteries with clots, as well as pathologic changes consistent with Kawasaki disease. Kawasaki disease is now recognized worldwide. Why cases began to emerge across all continents around the 1960s and 1970s is unclear. Possible explanations could include confusion with other diseases such as scarlet fever, and easier recognition stemming from modern healthcare factors such as the widespread use of antibiotics. In particular, old pathological descriptions from Western countries of infantile polyarteritis nodosa coincide with reports of fatal cases of Kawasaki disease.
