| peripheral tabes | A syndrome having the characteristics of tabetic neurosyphilis but not due to syphilis. Synonym: Leyden's ataxia, peripheral tabes, pseudoataxia. (05 Mar 2000) |

| peripheral vision | Vision resulting from retinal stimulation beyond the macula. Synonym: indirect vision. (05 Mar 2000) |
| neuroectodermal tumour, peripheral | A heterogeneous group of malignant neoplasms arising in either supportive structures or neuronal tissue. They occur in adolescents and young adults. This tumour shares a number of characteristics with ewing's sarcoma: it is highly cellular and consists of a monotonous pattern of primitive-appearing round cells. The chest wall is the most common site but the trunk, abdomen, and pelvis are other primary sites. (12 Dec 1998) |
| lymphoma, T-cell, peripheral | A group of malignant lymphomas thought to derive from peripheral T-lymphocytes in lymph nodes and other nonlymphoid sites. They include a broad spectrum of lymphocyte morphology, but in all instances express T-cell markers admixed with epithelioid histiocytes, plasma cells, and eosinophils. Although markedly similar to large-cell immunoblastic lymphoma (lymphoma, large-cell, immunoblastic), this group's unique features warrant separate treatment. (12 Dec 1998) |
| airway resistance | The opposition of the tracheobronchial tree to air flow: the mouth-to-alveoli pressure difference divided by the air flow. (12 Dec 1998) |
| ampicillin resistance | Nonsusceptibility of a microbe to the action of ampicillin, a penicillin derivative that interferes with cell wall synthesis. (12 Dec 1998) |
| androgen resistance syndromes | A class of disorders associated with 5a-steroid reductase deficiency, testicular feminization, and related disorders. Compare: steroid 5a-reductase, Reifenstein's syndrome, infertile male syndrome, testicular feminization syndrome. (05 Mar 2000) |
| antibiotic resistance | The ability of a bacterium tosynthesise a protein that neutralises an antibiotic. (09 Oct 1997) |
| antibiotic resistance gene | Genes in a microorganism which confer resistance to antibiotics, for example by coding for enzymes which destroy it, by coding for surface proteins which prevent it from entering the microorganism, or by being a mutant form of the antibiotic's target so that it can ignore it. (09 Oct 1997) |
| bacteriophage resistance | Resistance of a bacterial mutant to infection by a bacteriophage to which the parent (wild type) strain is susceptible. (05 Mar 2000) |
| beta-lactam resistance | Nonsusceptibility of an organism to the action of the beta-lactam antibiotics. (12 Dec 1998) |
| capillary resistance | The resistance offered to the flow of blood through the capillary portion of the peripheral vascular bed. (12 Dec 1998) |
| capillary resistance test | A tourniquet test used to determine presence of vitamin C deficiency or thrombocytopenia; a circle 2.5 cm in diameter, the upper edge of which is 4 cm below the crease of the elbow, is drawn on the inner aspect of the forearm, pressure midway between the systolic and diastolic blood pressure is applied above the elbow for 15 minutes, and a count of petechiae within the circle is made: 10, normal; 10 to 20, marginal zone; over 20, abnormal. See: Rumpel-Leede test. Synonym: capillary resistance test, vitamin C test. (05 Mar 2000) |
| resistance | The failure of a condition to respond or remit following treatment. (16 Dec 1997) |
| resistance, antibiotic | The ability of bacteria and other microorganisms to withstand an antibiotic to which they were once sensitive (and were once stalled or killed outright). Also called drug resistance. (12 Dec 1998) |
