PREVENTION, SYMPTOMS AND TREATMENT „ 



most suitable for the larger patients. This treatment is indicated 

 for either cerebral hemorrhage or congestion. Recovery from the 

 former is slow and often incomplete, with persisting paresis, so that 

 treatment is rarely advisable. Frequent change of position of the 

 patient is necessary in unconsciousness, and catheterization and 

 enemata. To facilitate resolution of hemorrhage, sodium iodide 

 (H., gss; D., gr. x, thrice daily) and strychnine (H., gr. i in 

 solution on tongue; D., gr. i/ioo to gr. 1/30 in pill three times 

 a day) may be given after the first two weeks. Massage and far- 

 adism to the muscles also aid recovery in paralyses. 



Cholera. 



See Fowl Cholera (p. 100). 



Chorea. 



This is a nervous disorder characterized by irregular involun- 

 tary movements of voluntary muscles, usually ceasing during sleep. 

 It attacks more often the young, and has been seen in horses, cattle, 

 pigs, cats and dogs, being most frequent in the latter. It is asso- 

 ciated often with endocarditis and arthritis, but whether these are 

 primary or secondary diseases is unknown. 



Chorea is thought to be due to a special infection, but this is 

 uncertain. Reflex causes, as the presence of intestinal worms, are 

 said to predispose. Anemia often accompanies chorea, and chorea 

 frequently follows canine distemper. Stringhalt in horses is classed 

 with chorea by some. 



The severity of chorea varies from twitching of certain groups 

 of muscles to constant motion of the whole body. Usually there is 

 jerking of some part of the body, as the head and neck, with twitch- 

 ing of the facial muscles and jaw, or of the fore or hind legs. The 

 movements occur when the patient is at rest, and even when lying 

 down, but not usually during sleep. 



Treatment. — Rest and attention to hygiene are most important.
