| lupus nephritis | Glomerulonephritis associated with systemic lupus erythematosus. It is classified into four histologic types: mesangial, focal, diffuse, and membranous. (12 Dec 1998) |
| lupus papillomatosus | A tuberculous skin lesion having a warty surface with a chronic inflammatory base seen on the hands in adults and lower extremities in children, with marked hypersensitivity to tuberculous antigens. See: postmortem wart. Synonym: lupus papillomatosus, lupus verrucosus, tuberculous wart, verrucous scrofuloderma. (05 Mar 2000) |
| lupus pernio | Sarcoid lesions, clinically resembling frostbite and microscopically resembling lupus vulgaris, involving ears, cheeks, nose, hands, and fingers. (05 Mar 2000) |
| lupus profundus | A subcutaneous panniculitis with marked lymphocyte infiltration of fat lobules giving rise to deep-seated, firm, rubbery nodules that sometimes become ulcerated, usually of the face; may occur in systemic and localised lupus erythematosus. Synonym: lupus profundus. (05 Mar 2000) |
| lupus sebaceus | Lupus erythematosus with lesions on the face in butterfly areas. (05 Mar 2000) |
| lupus serpiginosus | A cutaneous tuberculous lesion that spreads peripherally, healing centrally with scar formation. (05 Mar 2000) |
| lupus superficialis | Skin disease in which there are red scaly patches, especially over the nose and cheeks. May be a symptom of systemic lupus erythematosus. (18 Nov 1997) |
| lupus tuberculosus | Cutaneous tuberculosis with characteristic nodular lesions on the face, particularly about the nose and ears. Synonym: lupus tuberculosus, tuberculosis cutis luposa. (05 Mar 2000) |
| lupus verrucosus | A tuberculous skin lesion having a warty surface with a chronic inflammatory base seen on the hands in adults and lower extremities in children, with marked hypersensitivity to tuberculous antigens. See: postmortem wart. Synonym: lupus papillomatosus, lupus verrucosus, tuberculous wart, verrucous scrofuloderma. (05 Mar 2000) |
| lupus vulgaris | Cutaneous tuberculosis with characteristic nodular lesions on the face, particularly about the nose and ears. Synonym: lupus tuberculosus, tuberculosis cutis luposa. (05 Mar 2000) |
| adhesion phenomenon | A phenomenon manifested by the adherence of antigen-antibody-complement complex to "indicator cells" (microorganisms, platelets, leukocytes, or erythrocytes), the reaction being sensitive and specific for the antigen and antibody in the complex. Synonym: erythrocyte adherence phenomenon, immune adherence phenomenon, red cell adherence phenomenon. (05 Mar 2000) |
| AFORMED phenomenon | As induced pulsus alternans progresses, a state in which alternating heart depolarisations fail to eject any blood, thus allowing longer diastolic filling; the subsequent beat is then able to produce a significant ejection; at high rates the cardiac minute volume and blood pressure may appear normal. Origin: Alternating, failure of response, mechanical, to electrical depolarisation (05 Mar 2000) |
| all-or-nothing phenomenon | <physiology> Refers to the phenomenon where the strength of a nerve impulse is not dependent on the strength of the stimulus. Instead, there is a threshold level of stimulus strength that must be reached before the nerve will fire an impulse (at full capacity). Below the threshold, the nerve will not fire at all. <cardiology> It also refers to the same phenomenon observed in the heart muscle, which will either contract fully or not at all. <psychology> In studies of behaviour, it refers to the same phenomenon where a behavioural stimulus will either produce a complete response or no response at all. Also called all-or-nothing principle, all-or-none law, all-or-none responsiveness, etc. (15 Nov 1997) |
| Anrep phenomenon | Homeometric autoregulation of the heart whereby cardiac performance improves as the afterload (aortic pressure) is increased. (05 Mar 2000) |
