CHICKASHA , a See also:city and the See also:county-seat of Grady county, See also:Oklahoma, U. S. A., near the Washita See also:river, about 45 M. S. S. W. of Oklahoma city. Pop. (1900) 3209; (1907) 7862, including 1043 negroes; (1910) 10,320. Chickasha is served by the St See also: CHICKEN-PDX (Syn. varicella, a See also:Low Latin diminutive of variola), a specific contagious disease characterized by an eruption of vesicles in the skin. The disease usually occurs in epidemics, and is one of childhood, the patients being generally between two and six years old. The See also:incubation See also:period is from ten to fifteen days; there are practically no prodromal symptoms, the only indication being a slight amount of See also:fever for some twenty-four See also:hours, after which the eruption makes its See also:appearance. A number of raised red papules appear on the See also:trunk, either on the back or See also:chest; in from twelve to twenty-four hours these develop into tense vesicles filled with a clear fluid, which in another See also:thirty-six hours or so becomes opalescent. During the See also:fourth See also:day these vesicles dry and shrivel up, and the scabs fall off, leaving as a See also:rule no scar. Fresh spots appear during the first three days, so that at the end of that See also:time they can be seen in all stages of growth and decay. The eruption is most marked on the chest, but it also occurs on the See also:face and limbs, and on the mucous membrane of the mouth and See also:palate. The temperature begins to fall after the appearance of the rash, but a certain slight amount may persist after the disappearance of all symptoms. It rarely rises above See also:Io2 F. The disease runs a very favourable course in the See also:majority of cases, and after effects are rare. One attack does not confer See also:immunity, and in numerous cases one individual has had three attacks. The See also:diet should be See also:light, and the patient should be prevented from scratching the spots, which would See also:lead to ulceration and scarring. After the first few days there is no See also:necessity to confine the patient to See also:bed. In the large majority of cases, it is easy to distinguish the disease from smallpox, but in certain patients it is very difficult. The See also:chief points in the See also:differential diagnosis are as follows. (1) In chicken-pox the rash is distributed chiefly on the trunk, and less on the limbs. (2) Some of the vesicles are See also:oval, whereas in smallpox they are always hemispherical. They are also more superficial, and have not at the outset the hard shotty feeling of the more virulent disease. (3) The vesicles attain their full growth within twelve to twenty-four hours. (4) The pustules are usually monocular. (5) There is no.prodromal period. Additional information and CommentsThere are no comments yet for this article.
