Homan’s sign test also called dorsiflexon sign test is a physical examination procedure that is used to test for Deep Vein Thrombosis (DVT). A positive Homan’s sign in the presence of other clinical signs may be a quick indicator of DVT. Clinical evaluation alone cannot be relied on for patient management, but when carefully performed, it remains useful in determining the need for additional testing (like D-dimer test, ultrasonography, multidetector helical computed axial tomography (CT), and pulmonary angiography) [1][2].

Pulmonary edema Email this page to a friend Email this page to a friend Facebook Twitter Google+ Pulmonary edema is an abnormal buildup of fluid in the lungs. This buildup of fluid leads to shortness of breath. Causes Pulmonary edema is often caused by congestive heart failure. When the heart is not able to pump efficiently, blood can back up into the veins that take blood through the lungs. As the pressure in these blood vessels increases, fluid is pushed into the air spaces (alveoli) in the lungs. This fluid reduces normal oxygen movement through the lungs. These two factors combine to cause shortness of breath.

Multiple sclerosis (MS) is a disease of the central nervous system estimated to affect 2.3 million people worldwide. It is a chronic disease in which the immune system abnormally attacks the insulation and support around the nerve cells (myelin sheath) in the brain, spinal cord and optic nerves, causing inflammation and consequent damage. MS is a leading cause of non-traumatic disability in young people, usually striking between 20 and 40 years of age. There is no cure for MS, but research continues to better understand and treat the disease.
