Sheldon-area historical tornado activity is below South Carolina state average. It is 32% smaller than the overall U.S. average. On 4/9/1998, a category F3 (max. wind speeds 158-206 mph) tornado 40.7 miles away from the Sheldon place center killed 2 people and injured 17 people and caused $3 million in damages.
Similar results have been found in other studies [17] [18]. Based on these reports we have defined hard-to-heal ulcers in this study as venous leg ulcers with an initial area of 10cm2 or greater and a duration of six months or more.
Duration of therapy for endocarditis, which is a life-threatening infection, is at least 4 weeks. The combination of a beta-lactam and an aminoglycoside (usually gentamicin) is advocated, because it increases bacterial killing in vitro and in animal models of endocarditis.
