But when something upsets the balance of these organisms in your gut, otherwise harmless bacteria can grow out of control and make you sick. One of the worst offenders is a bacterium called Clostridium difficile(C. difficile, or C. diff).

Acute compartment syndrome refers to ischemic tissue damage secondary to elevated pressures in the enclosed compartments of the lower legs or forearm. When the tissue pressure in an enclosed compartment exceeds the perfusion pressure, the resulting diminished tissue perfusion and compromised blood flow to the muscles and nerves inevitably lead to ischemic tissue necrosis.
