PARASITIC DISEASES OF THE NOSE. 



Among these may be named : 



LEECH BITES. 



Form of wound, leeches in posterior nares, discharge of blood, mucus, 

 sneezing, snorting, dysphagia, anorexia, unthriftiness, ansemia. Treat- 

 ment, removal, sodium chloride, tar fumes, ether on sponge. 



Though it more commonly attacks the mouth and hps yet the 

 leech (Hirudo Decora) will sometimes fasten itself inside the 

 nose when that is plunged in water. Its bite is to be recognized 

 by its triangular shape. When taken in by the mouth it may 

 fasten itself in the posterior nares where it is difflcult to recognize 

 its presence. In the anterior nares it can be readily discovered 

 and removed, but in the posterior nares it may maintain its hold 

 indefinitely. There appear in the nasal discharge streaks or clots 

 of blood which may also show at the corners of the mouth. 

 Sneezing, snorting, and difficulty of deglutition, may draw atten- 

 tion to the trouble, and in protracted cases signs of anaemia, in- 

 appetence, unthriftiness and general weakness. The most 

 effective treatment is to remove the leech with the fingers, but as 

 they cannot always be reached in this way, an injection of a 

 strong solution of common salt may be used. Blaise succeeded 

 by burning tar under the nose twice a day, and Louvigny by in- 

 troducing a staff bearing a sponge soaked in ether. 



COCCIDIAN CATARRH IN RABBITS. 



Coccidia in rabbit's nose, etc., inflammation, fatality. Treatment, sul- 

 phur dioxide. 



Zurn describes a contagious catarrh of rabbits caused by the 

 presence in the mucosa of the nose, pharynx, Eustachian tubes 

 and middle ears. of myriads of coccidia. They create acute irrita- 

 tion and prove fatal in many cases. Embedded in the mucosa 

 they are difficult to reach with medicinal agents, yet the free para- 

 sites may be destroyed by frequent fumigations with sulphtirous 

 acid, or by spraying or injecting the nose with its solution.
