| gene expression regulation, neoplastic | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in neoplastic tissue. (12 Dec 1998) |
|---|---|
| cell transformation, neoplastic | Cell changes manifested by escape from control mechanisms, increased growth potential, alterations in the cell surface, karyotypic abnormalities, morphological and biochemical deviations from the norm, and other attributes conferring the ability to invade, metastasize, and kill. (12 Dec 1998) |
| pregnancy complications, neoplastic | Neoplasms occurring during the course of pregnancy, or pregnancy during the course of a neoplastic disease. (12 Dec 1998) |
| neoplastic | <oncology, pathology> Pertaining to or like a neoplasm with new and abnormal growth, pertaining to neoplasia with the formation of a neoplasm. Origin: Gr. Plassein = to form (18 Nov 1997) |
| neoplastic arachnoiditis | Infiltration of subarachnoid space by neoplastic cells, typically medulloblastoma or metastatic carcinoma. Synonym: neoplastic arachnoiditis. (05 Mar 2000) |
| neoplastic endocrine-like syndromes | Endocrine syndromes due to hormone production by neoplasms of non-endocrine tissue, or by other than the usual endocrine tissues. They are often the first indication of a previously undetected neoplasm. (12 Dec 1998) |
| neoplastic meningitis | Infiltration of subarachnoid space by neoplastic cells, typically medulloblastoma or metastatic carcinoma. Synonym: neoplastic arachnoiditis. (05 Mar 2000) |
| neoplastic processes | The pathological mechanisms and forms taken by tissue during degeneration into a neoplasm and its subsequent activity. (12 Dec 1998) |
| neoplastic syndromes, hereditary | The condition of a pattern of malignancies within a family, but not every individual's necessarily having the same neoplasm. Characteristically the tumour tends to occur at an earlier than average age, individuals may have more than one primary tumour, the tumours may be multicentric, usually more than 25 percent of the individuals in direct lineal descent from the proband are affected, and the cancer predisposition in these families behaves as an autosomal dominant trait with about 60 percent penetrance. (12 Dec 1998) |
| acute demyelinating polyneuropathy | <neurology> A neurologic condition. Synonym: Guillain-Barre syndrome. Origin: Gr. Pathos = disease (27 Sep 1997) |
| acute inflammatory polyneuropathy | <neurology, syndrome> Acute infective polyneuritis that results in a form of peripheral neuropathy with temporary loss of movement and sensation due to inflammation of multiple nerves and loss of myelin. The exact cause is unknown but has been associated with an abnormal immune response to viral infection, particularly cytomegalovirus infection, in which there is cell-mediated immunity to a component of myelin. The disease may be autoimmune in origin and complete recovery can take up to six months. Synonym: Guillain-Barre syndrome (12 Jul 2000) |
| alcoholic polyneuropathy | <neurology> A disorder that occurs secondary to the damage to nerve cells from habitual alcohol abuse. The effects of alcoholic polyneuropathy may be due in part to the direct toxic effect alcohol has on nervous tissue in combination with specific nutritional deficiencies (for example B1 or thiamin deficiency and B12 deficiency). Common symptoms include sensory changes, numbness, tingling, muscle weakness, muscle cramps, heat intolerance, impotence, difficulty urinating, swallowing difficulty, speech impairment, diarrhoea and constipation. Origin: Gr. Pathos = disease (27 Sep 1997) |
| arsenical polyneuropathy | An axon loss polyneuropathy that results from subacute or chronic arsenic poisoning; almost always preceded by gastrointestinal symptoms; one of the heavy metal neuropathies. (05 Mar 2000) |
| axonal polyneuropathy | A type of polyneuropathy in which axon degeneration is the sole/predominant feature; many aetiologies, particularly toxic and metabolic; on nerve conduction studies, affects amplitudes of the responses, but does not cause conduction slowing or block. Synonym: axonal polyneuropathy. (05 Mar 2000) |
| axon loss polyneuropathy | A type of polyneuropathy in which axon degeneration is the sole/predominant feature; many aetiologies, particularly toxic and metabolic; on nerve conduction studies, affects amplitudes of the responses, but does not cause conduction slowing or block. Synonym: axonal polyneuropathy. (05 Mar 2000) |
