| 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) |
| apophysial fracture | Separation of apophysis from bone. (05 Mar 2000) |
| articular fracture | A fracture involving the joint surface of a bone. (05 Mar 2000) |
| atlas fracture | <radiology> Incidence: 4% of cervical spine injuries, site: posterior arch, anterior arch, massa lateralis, Jefferson fracture associated with: fractures of C7 (25%), fractures of C2 pedicle (15%), extraspinal fractures (58%) (12 Dec 1998) |
| avulsion fracture | A fracture that occurs when a joint capsule, ligament, or muscle insertion of origin is pulled from the bone as a result of a sprain dislocation or strong contracture of the muscle against resistance; as the soft tissue is pulled away from the bone, a fragment or fragments of the bone may come away with it. (05 Mar 2000) |
| axis fracture | <radiology> Incidence: 6% of cervical spine injuries, associated with atlas fractures in 8%, hyperflexion injury: odontoid fracture, type I avulsion of tip of odontoid (5-8%) difficult to detect, type II fracture through base of dens (54-67%) complication: nonunion, type III subdental injury (30-33%) prognosis: good, Differential diagnosis: os odontoideum, ossiculum terminale, hypoplasia/aplasia of dens, hyperextension injury: hangman's fracture (12 Dec 1998) |
| barton fracture | <radiology> Intra-articular fracture of distal radius, dorsal displacement of separated fragment, due to fall on outstretched hand see: wrist fractures (12 Dec 1998) |
