Toxic Shock Syndrome (TSS) was first recognized in children in 1978. In adults it was found that TSS occurs in menstruating women using very high absorbency tampons. These hogh absorbency tampons contain polyester foam and polyacrylate rayon that soak up magnesium from the vaginal discharge. Reduced magnesium level cause staphylocossus to produce large amount of toxin and causes TSS. The incidence of TSS is highest on the 4th day of menses when the menstrual becomes lesser. Certain women have the tendency to be highly susceptible to this toxin. ∼ Signs and symptoms of TSS: − Fever (with body temperature above 38.8OC / 102 OF).
