| edema | <clinical sign> The presence of abnormally large amounts of fluid in the intercellular tissue spaces of the body, usually applied to demonstrable accumulation of excessive fluid in the subcutaneous tissues. Oedema may be localised, due to venous or lymphatic obstruction or to increased vascular permeability or it may be systemic due to heart failure or renal disease. Collections of oedema fluid are designated according to the site, for example ascites (peritoneal cavity), hydrothorax (pleural cavity) and hydropericardium (pericardial sac). Massive generalised oedema is called anasarca. Origin: Gr. Oide ma = swelling (18 Nov 1997) |
|---|---|
| edema, cardiac | A manifestation of congestive heart failure caused by increased venous and capillary pressures and often associated with the retention of sodium by the kidneys. (12 Dec 1998) |
| arthropathy, neurogenic | Chronic progressive degeneration of the stress-bearing portion of a joint, with bizarre hypertrophic changes at the periphery. It is probably a complication of a variety of neurologic disorders, particularly tabes dorsalis, involving loss of sensation, which leads to relaxation of supporting structures and chronic instability of the joint. (12 Dec 1998) |
| autonomic neurogenic bladder | Malfunctioning bladder, secondary to low spinal cord lesions. (05 Mar 2000) |
| bladder, neurogenic | Any condition of dysfunction of the urinary bladder caused by a lesion of the central or peripheral nervous system. (12 Dec 1998) |
| reflex neurogenic bladder | An abnormal condition of bladder function whereby the bladder is cut off from upper motor neuron control, but where the lower motor neuron arc is still intact. (05 Mar 2000) |
| neurogenic | <embryology> Arising from or caused by the nervous system. Origin: Gr. Gennan = to produce (27 Sep 1997) |
| neurogenic atrophy | Abnormalities of the skin, hair, nails, subcutaneous tissues and bone, caused by peripheral nerve lesions. Synonym: neuritic atrophy, neurogenic atrophy, neurotrophic atrophy, trophic changes. (05 Mar 2000) |
| neurogenic bladder | A dysfunction of the bladder due a malfunction of the autonomic nerves which control bladder function. (27 Sep 1997) |
| neurogenic fracture | A fracture in bone weakened by disease of the nerve supply. (05 Mar 2000) |
| neurogenic gene | Best described in Drosophila, genes that are required to determine a neuronal fate. Examples: Notch, Delta. (18 Nov 1997) |
| 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) |
| neurogenic tonus | Contraction of a muscle caused by the influence of its extrinsic nerve supply (05 Mar 2000) |
| nonneurogenic neurogenic bladder | <urology> Detrusor-sphincter incoordination with urinary incontinence, constipation, urinary tract infection, upper tract changes. Synonym: Hinman syndrome, pseudoneurogenic bladder. (05 Mar 2000) |
| disputed neurogenic thoracic outlet syndrome | <syndrome> A highly controversial disorder in which the brachial plexus is reputedly repressed at one or more sites along its course, particularly within the interscalene triangle, and between the normal first thoracic rib and some other structures; frequently attributed to trauma (particularly automobile accidents, and most often diagnosed in young to middle-aged women; no characteristic clinical presentation, although forequarter pain is characteristic; no definite objective findings are present, and no undisputed ancillary diagnostic studies are available.
