 Scarlet Fever. Jour. Bost. Soc. Med. Sci., , , ^ • 1 • n r j • 4.1. 



March i8qq ^^^ bactenologically connrmed in the 



case of diphtheria by examination of 

 the nose and throat, were examined in order to ascertain whether the antra and 

 other accessory sinuses were involved. In none of the cases were there any 

 symptoms pointing to disease of the antra or other sinuses. Three of the cases 

 were adults aged respectively nineteen, twenty-two, and twenty-four years, two 

 were ten years old, one twelve, and all the rest between two and six years. 

 Most of the cases in which there was an invasion of the sinuses died in from 

 four to ten days, the average being the ninth day. The earliest infections 

 occurred in diphtheria on the second and third days after membrane formation. 

 All the scarlet fever cases with disease of the sinuses died between the ninth 

 and fifteenth days. 



The cases are divided as follows : diphtheria, thirty-nine cases ; diphtheria 

 complicated by scarlet fever, five cases ; diphtheria complicated by measles, two 

 cases ; scarlet fever, four cases. In the examination of the sinuses precautions 

 were taken not to introduce organisms from the outside. Cultures were 

 made from the contents of the sinuses, and controlled by smears, and infection of 

 the frontal, sphenoidal, and ethmoidal sinuses was only accepted as conclusive 

 when a definite exudate was found, and in which the results obtained by smears 

 and culture were the same. 



In twenty-five of the thirty-nine uncomplicated diphtheria cases, inflammatory 

 changes were found in the accessory sinuses, as follows : both antra, sixteen ; 

 both antra, sphenoidal, and ethmoidal sinuses, two ; one antrum only, five ; 

 sphenoidal sinuses only, five. Of the eighteen double antral cases the exudate, 

 on both sides, in three was a thick yellow pus ; in three, a sero-purulent fluid ; in 

 three, a thin, cloudy, serous fluid ; in one, a purulent fluid with membrane ; in 

 one, a cloudy serous fluid with membrane ; and in seven, a thin mucoid fluid.
