| shock, septic | Shock due to circulatory insufficiency caused most commonly by gram-negative bacteraemia. It is less often the result of the persistent presence of other micro-organisms in the blood (fungaemia, viraemia); in rare instances, it is caused by gram-positive organisms, but with different symptomatology.

| shock, shell | The World War I name for what is known today as posttraumatic stress, this is a psychological disorder that develops in some individuals who have had major traumatic experiences (and, for example, have been in a serious accident or through a war). The person is typically numb at first but later has symptoms including depression, excessive irritability, guilt (for having survived while others died), recurrent nightmares, flashbacks to the traumatic scene, and overreactions to sudden noises. Posttraumatic stress became known as such in the 70s due to the adjustment problems of some vietnam veterans.shots, allergy: known medically as allergy desensitization or allergy immunotherapy, the injections are designed to stimulate the immune system with gradually increasing doses of the substances to which a person is allergic, the aim being to modify or stop the allergy war (by reducing the strength of the IgE and its effect on the mast cells). This form of treatment is very effective for allergies to pollen, mites, cats, and especially stinging insects (e.g., bees, hornets, yellowjackets, wasps, velvet ants, fire ants). Allergy immunotherapy usually takes 6 months to a year to become effective and injections are usually required for 3-5 years. (12 Dec 1998) |

| shock tube | <radiobiology> A gas-filled tube used in plasma physics to quickly ionize a gas. A capacitor bank charged to a high voltage is discharged into the gas at one tube end to ionize and heat the gas, producing a shock wave that may be studied as it travels down the tube. (09 Oct 1997) |
| shock wave | <radiobiology> Wave produced (for example, in a gas or plasma) as a result of a sudden violent disturbance. To produce a shock wave in a given region, the disturbance must take place in a shorter time than the time required for sound waves to traverse the region. (09 Oct 1997) |
| shock wave lithotripsy | A method of fragmenting calculi. (05 Mar 2000) |
| hypovolaemic shock | A state of inadequate tissue perfusion that occurs secondary to an abnormally low circulating blood volume. May occur as the result of severe dehydration. (27 Sep 1997) |
| hypovolemic shock | A medical condition where there are abnormally low levels of blood plasma in the body, such that the body is unable to properly maintain blood pressure, cardiac output of blood, and normal amounts of fluid in the tissues. This results in a state of deep physical depression. (09 Oct 1997) |
| spinal shock | Transient depression or abolition of reflex activity below the level of an acute spinal cord injury or transection. (05 Mar 2000) |
| neurogenic shock | <neurology> This form of distributive shock results from a change in systemic vascular resistance, mediated by a neurologic injury (for example, head injury, spinal cord injury). Synonym: spinal shock. (27 Sep 1997) |
| nitroid shock | A syndrome resembling that produced by the administration of a large dose of a nitrite, sometimes caused by a too rapid intravenous injection of arsphenamine or some other drug. See: nitritoid reaction. (05 Mar 2000) |
