| pyoderma | <dermatology> Any purulent skin disease. Synonym: pyodermia. (18 Nov 1997) |
| pyoderma gangrenosum | An ulcerating condition of skin resulting in heaped borders with a typical appearance. Pyoderma gangrenosum appears to be mediated by the immune system, but the exact cause is unknown. The lesion(s) usually begin as a soft nodule on the skin which proceeds to ulcerate. The ulcer enlarges and the skin at the edge is purple-red. Ulcers can become quite large. This condition is associated with several other diseases, some of which are ulcerative colitis, crohn's disease, rheumatoid arthritis, leukaemia, and cryoglobulinaemia. Pyoderma gangrenosum is usually responsive to corticosteroids. (12 Dec 1998) |
| pyoderma vegetans | A benign fungating granulomatous mass caused by chronic pyogenic infection. Synonym: pyoderma vegetans. (05 Mar 2000) |
| CS2 secondary alkylsulfohydrolase | <enzyme> From comamonas terrigena Registry number: EC 3.1.6.- Synonym: cs2 sa sulfohydrolase (26 Jun 1999) |
| protein structure, secondary | The stage in the development of protein structure in which regular hydrogen-bond interactions within contiguous stretches of polypeptide chain give rise to alpha helices and beta sheets. This is the first folding level of protein building. (12 Dec 1998) |
| secondary | Second or inferior in order of time, place or importance, derived from or consequent to a primary event or thing. Origin: L. Secundarius, secundus = second (18 Nov 1997) |

| secondary aerodontalgia | Pain referred to the dental area from an area of aerosinusitis. (05 Mar 2000) |
| secondary agammaglobulinaemia | Immunodeficiency in which there is no evident defect in the lymphoid tissues, but rather hypercatabolism or loss of immunoglobulins such as occurs in familial idiopathic hypercatabolic hypoproteinaemia or in defects associated with the nephrotic syndrome. Synonym: secondary agammaglobulinaemia, secondary antibody deficiency, secondary hypogammaglobulinaemia. (05 Mar 2000) |
| secondary alcohol | An alcohol characterised by the bivalent atom group (05 Mar 2000) |
| secondary aldosteronism | Aldosteronism resulting not from a defect intrinsic to the adrenal cortex but from a stimulation of hormonal secretion caused by extra-adrenal disorders; associated with increased plasma renin activity and occurs in heart failure, nephrotic syndrome, cirrhosis, and hypoproteinaemia.
