| evolution, planetary | Creation and development of bodies within solar systems, includes study of early planetary geology. (12 Dec 1998) |
| global | The complete, generalised, overall, or total aspect. (05 Mar 2000) |
| global aphasia | In which all aspects of speech and communication are severely impaired. at best, patients can understand or speak only a few words or phrases; they cannot read or write. Synonym: mixed aphasia, total aphasia. (05 Mar 2000) |
| global ecology | <study> The study of the relationship of organisms to each other and to their environment on a global scale. (09 Oct 1997) |
| global paralysis | Paralysis of both whole sides of the body; survival is usually of short duration. Synonym: generalised paralysis. (05 Mar 2000) |
| global stability | <ecology> The ability of an ecological unit (such as a habitat) or taxonomic unit to withstand great disturbances without being greatly affected. (09 Oct 1997) |
| transient global amnesia | A memory disorder seen in middle aged and elderly persons characterised by an episode of amnesia and bewilderment which persists for several hours; during the episode the patient has a memory defect for present and recent past events, but is fully alert, oriented, capable of high-level intellectual activity, and has a normal neurological examination. Typically, these amnesic episodes occur spontaneously, and most patients experience only one; of uncertain aetiology-probably ischemic, but not due to atherosclerosis. (05 Mar 2000) |
| Armanni-Ebstein change | Glycogen vacuolization of the loops of Henle, seen in diabetics before the introduction of insulin. Synonym: Armanni-Ebstein change. (05 Mar 2000) |
| Baggenstoss change | Distention of pancreatic acini by proteinaceous secretion, seen in dehydration. (05 Mar 2000) |
| change | An alteration; in pathology, structural alteration of which the cause and significance is uncertain. Synonym: shift. (05 Mar 2000) |
| change of life | Colloquialism for menopause, climacteric. (05 Mar 2000) |
| chemical change | A process in which one or more substances are changed into one or more different substances. (09 Oct 1997) |
| minimal-change disease | <nephrology> A disorder of the kidneys which largely affects the glomerulus, the blood filtering structure. This disorder is one common cause of nephrotic syndrome, minimal glomerular changes, in children affecting 2 to 3 children per 100,000 population under age 16 in the USA. Minimal change disease is also seen rarely in adults. The cause is unknown but may be related to an autoimmune illness. It is marked by oedema, albuminuria, and an increase in cholesterol in the blood, but otherwise with fairly good renal function. Tubular epithelium is vacuolated by cholesterol droplets, but the glomeruli show only that the foot processes of the glomerular epithelial cells are fused, probably secondary to the proteinuria; the cause of the increased glomerular permeability to plasma protein is unknown. Risk factors include a history for a immune disorder, recent immunisation or a bee sting. Diagnosis is made by renal biopsy. Treatment include systemic corticosteroids which are usually quite effective in curing this disease. Other medications include chlorambucil and cyclophosphamide. In most cases, a moderate protein diet (1 gram protein per Kg body weight per day) will be recommended. Salt (sodium) restriction can be helpful to reduce swelling and vitamin D is usually supplemented. Synonym: lipoid nephrosis (27 Sep 1997) |
