| intermittent positive-pressure ventilation | Application of positive pressure to the inspiratory phase when the patient has an artificial airway in place and is connected to a ventilator. See: controlled mechanical ventilation (12 Dec 1998) |
| intermittent pulse | Irregularity of the heart due to extrasystoles which are too weak to open the semilunar valves; often owing to the long pause following the premature beat, extra long pauses equal to two regular cycles occur from time to time between pulse beats. Synonym: pulsus intercidens. (05 Mar 2000) |
| intermittent sterilization | Exposure to a temperature of 100°C (flowing steam) for a definite period, usually an hour, on each of several days; at each heating the developed bacteria are destroyed; spores, which are unaffected, germinate during the intervening periods and are subsequently destroyed. Synonym: discontinuous sterilization, intermittent sterilization, tyndallization. (05 Mar 2000) |
| intermittent tetanus | 1. Hyperexcitability of nerves and muscles due to decrease in concentration of extracellular ionised calcium, which may be associated with such conditions as parathyroid hypofunction, vitamin D deficiency and alkalosis or result from ingestion of alkaline salts, it is characterised by carpopedal spasm, muscular twitching and cramps, laryngospasm with inspiratory stridor, hyperreflexia and choreiform movements. 2. Tetanus. (18 Nov 1997) |
| intermittent torticollis | Stiff neck due to spasm of the neck muscles. Synonym: intermittent torticollis. (05 Mar 2000) |
| acute malaria | A form of malaria that may be intermittent or remittent, consisting of a chill accompanied and followed by fever with its attendant general symptoms, and terminating in a sweating stage; the paroxysms, caused by release of merozoites from infected cells, recur every 48 hours in tertian (vivax or ovale) malaria, every 72 hours in quartan (malariae) malaria, and at indefinite but frequent intervals, usually about 48 hours, in malignant tertian (falciparum) malaria. (05 Mar 2000) |
| algid malaria | A form of falciparum malaria chiefly involving the gut and other abdominal viscera; gastric algid malaria is characterised by persistent vomiting; dysenteric algid malaria is characterised by bloody diarrheic stools in which enormous numbers of infected red blood cells are found. (05 Mar 2000) |
| autochthonous malaria | Disease acquired by mosquito transmission in an area where malaria regularly occurs. (05 Mar 2000) |
| avian malaria | <veterinary> Plasmodial infections of domestic and wild birds, transmitted chiefly by culicine mosquitoes. (05 Mar 2000) |
| benign tertian malaria | <disease, microbiology> A type of malaria caused by the protozoan Plasmodium vivax, it isthe most common form of the disease, is rarely fatal but is the most difficult to cure, and is characterised by fevers that typically occur every other day. (11 Nov 1997) |
| bilious remittent malaria | A form of falciparum malaria characterised by bilious vomiting, bilious diarrhoea, etc. (05 Mar 2000) |
| malaria | In humans, the set of diseases caused by infection by the protozoans Plasmodium vivax causing the tertian type, P. Malariae the quartan type and P. Falciparum the quotidian or irregular type of disease, the names referring to the frequency of fevers. The fevers occur when the merozoites are released from the erythrocytes. The organisms are transmitted by the Anopheles mosquito. (18 Nov 1997) |
| malaria, avian | Any of a group of infections of fowl caused by protozoa of the genera plasmodium, leucocytozoon, and haemoproteus. The life cycles of these parasites and the disease produced bears strong resemblance to those observed in human malaria. (12 Dec 1998) |
| malaria, cerebral | A condition that is most commonly seen as a severe complication of malaria, falciparum mainly involving the brain. It has also been reported to occur as a result of infection with other plasmodium species. This disease is often fatal and presents as disturbances in consciousness ranging from somnolence to coma, major motor seizures, and organic psychosis. The onset may be gradual or sudden following a convulsion. (12 Dec 1998) |
