In 1851 they were still to some extent a distinct people, but exist now only as one of the component divisions of the (Southern) Cheyenne tribe, in no respect different from the others. Under the name Staitan (a contraction of SÅ­tai-hitÃ¤n, pl. SÅ­tai-hitÃ¤nio, âSÅ­tai menâ) they are mentioned by Lewis and Clark in 1804 as a small and savage tribe roving west of the Black Hills.
Styes are usually caused by infections of the oil glands in the eyelid. Very frequently, they are infected by bacteria, most commonly Staphylococcus bacteria. Seborrhea (excessive oily discharge from the glands) may increase the likelihood of developing one of these infections.
1 A sty or a chalazion causes eye pain because of local irritation. 2  Both cause a lump which can be seen or felt within the eyelid formed by a blocked oil gland. 3  This lump causes irritation to the eye, can be very painful to the touch, and is seen in both children and adults.
