Unusual Cure of Angina Pectoris after Virus Disease

Sir,?I read with interest the note by Dr. K. S. Hossain on ' Unusual cure of angina pectoris after virus disease', in your issue of November 1949, p. 502. Many years back I read before the then Kathiawar Medical Society at Rajkot, notes of a case of whooping cough which got cured after the patient developed an attack of measles. I gave my notes the heading ' Antagonism in diseaseThe patient was a male child of 4 years age suffering from whooping cough. He developed measles of the seventh day after he started whooping cough. The relief from whooping cough was very striking, the fits of coughing and subsequent vomiting being abolished from the third day of his having measles. In the Journal of the American Medical Association for 3rd September, 1949, p. 24, Dr. Nathan Gorin of Boston has reported three cases of chronic and intractable asthma in which there was relief of asthma with the appearance of jaundice due to (1) infectious hepatitis, (2) presumable homologous serum hepatitis and (3) metastatic adenocarcinoma of the liver. One could only speculate on the cause or causes of such a dramatic relief in cases in which, it seems, one disease condition elbows out another.
