| acute intermittent porphyria | <gastroenterology, haematology> A group of rare inherited metabolic disorders that result from a disturbance in porphyrin metabolism, causing increased formation and excretion of porphyrin or its precursors. It is caused by hepatic overproduction of d-aminolevulinic acid, which has greatly increased urinary excretion and of porphobilinogen, and some increase of uroporphyrin, due to a deficiency of porphobilinogen deaminase. Clinical features: intermittent acute attacks of hypertension, abdominal colic, psychosis, and polyneuropathy, but with no photosensitivity. It is exacerbated by the ingestion of certain drugs such as; barbiturates). Inheritance: autosomal dominant. (20 Sep 2002) |

| synchronised intermittent mandatory ventilation | Intermittent mandatory ventilation spontaneously initiated by the patient, to increase tidal volume, and subsequently synchronised with patient's respiratory cycle. Synonym: synchronised intermittent mandatory ventilation. (05 Mar 2000) |
| intermittent | Occurring at separated intervals, having periods of cessation of activity. (18 Nov 1997) |
| intermittent acute porphyria | <gastroenterology, haematology> A group of rare inherited metabolic disorders that result from a disturbance in porphyrin metabolism, causing increased formation and excretion of porphyrin or its precursors. It is caused by hepatic overproduction of d-aminolevulinic acid, which has greatly increased urinary excretion and of porphobilinogen, and some increase of uroporphyrin, due to a deficiency of porphobilinogen deaminase.
