DRUJ stress test: With this provocation maneuver, the wrist is held in pronated or supinated position, while the physician attempts to manipulate the distal ulna in dorsal and volar direction. Painful laxity indicates DRUJ instability and suggests RUL pathology. [2] Ulnar grind test: The forearm is fixated and the wrist is held in dorsiflexion.
The psoas sign, also known as Cope's sign (or Cope's psoas test [1]) or Obraztsova's sign, [2] is a medical sign that indicates irritation to the iliopsoas group of hip flexors in the abdomen, and consequently indicates that the inflamed appendix is retrocaecal in orientation (as the iliopsoas muscle is retroperitoneal).
The plaque reduction neutralization test is used to quantify the titer of neutralizing antibody for a virus. [1] [2] The serum sample or solution of antibody to be tested is diluted and mixed with a viral suspension. This is incubated to allow the antibody to react with the virus. This is poured over a confluent monolayer of host cells.
Type 2 inflammation is a pattern of immune response. Its physiological function is to defend the body against helminths , but a dysregulation of the type 2 inflammatory response has been implicated in the pathophysiology of several diseases.
The utility of the modified Allen's test is questionable, [4] and no direct correlation with reduced ischemic complications of radial artery cannulation have ever been proven. In 1983, Slogoff and colleagues reviewed 1,782 radial artery cannulations and found that 25% of them resulted in complete radial artery occlusion, without apparent ...
Pericarditis (PER-i-kar-DYE-tis) is inflammation of the pericardium, the fibrous sac surrounding the heart. [8] Symptoms typically include sudden onset of sharp chest pain, which may also be felt in the shoulders, neck, or back. [1] The pain is typically less severe when sitting up and more severe when lying down or breathing deeply. [1]
The cold pressor test is a cardiovascular test performed by immersing the hand into an ice water container, usually for one minute, and measuring changes in blood pressure and heart rate. These changes relate to vascular response and pulse excitability. Some research suggests that the outcome of the cold pressor test can help to predict ...
Vasculitis is a group of disorders that destroy blood vessels by inflammation. [2] Both arteries and veins are affected. Lymphangitis (inflammation of lymphatic vessels) is sometimes considered a type of vasculitis. [3] Vasculitis is primarily caused by leukocyte migration and resultant damage.
