In contrast, systemic diseases that are associated with fluid retention generally cause the same amount of edema in both legs, and can also cause edema and swelling elsewhere in the body. The response to therapy with diuretic drugs in patients with venous insufficiency tends to be unsatisfactory. This is because the continued pooling of fluid in the lower extremities makes it difficult for the diuretics to mobilize the edema fluid. Elevation of the legs periodically during the day and the use of compression stockings may alleviate the edema. Some patients require surgical treatment to relieve chronic edema that is caused by venous insufficiency.
There are two stages of Rocky Mountain spotted fever: Subclinical and acute. In the subclinical stage, dogs are infected, but do not show outward signs of the disease though they may have laboratory test abnormalities. These dogs may recover quickly.
How is Rocky Mountain spotted fever spread? Rocky Mountain spotted fever is spread by the bite of an infected tick (the American dog tick or the lone-star tick) or by contamination of the skin with tick blood or feces. Person-to- person transmission does not occur.
