Carbon dioxide snow has been shown by Mitchell to be an efficient local application for oriental sore.

The remarkable effect of antimony on the parasites of leishmaniasis was first noted in the treatment of the cutaneous types. The treatment is similar to that described under kala-azar. The effect of the drug is less pronounced on the lesions of the mucous membranes.

CHAPTER IX
DYSENTERY

Definition and Synonyms

Definition.—The designation dysentery refers to a symptom-complex of (1) small, frequently passed mucous or muco-sanguinolent stools and (2) pains connected with spasm of the sphincter ani (tenesmus) or intestinal gripings (tormina).

The condition may be set up by numerous causes but of these two so outweigh the others that it is usual to have in mind either bacillary or amoebic dysentery when the term is employed.

Synonyms.—The Bloody Flux. French: Dysenterie. German: Ruhr.

General Considerations

As will be noted in the sections dealing with amoebic and bacillary dysentery our present knowledge of these conditions is of recent date. There was so much that was etiologically, epidemiologically and clinically contradictory that the subject was impossible of elucidation until the existence of a group of dysentery bacilli was generally accepted, following the reporting, in 1898, by Shiga, of his bacillus of dysentery.
