| pericardial rub | A to-and-fro grating, rasping, or, rarely, creaking sound heard over the heart in some cases of pericarditis, due to rubbing of the inflamed pericardial surfaces as the heart contracts and relaxes; during normal sinus rhythm it is usually triphasic; during any rhythm it may be biphasic or uniphasic. Synonym: pericardial rub, pericardial friction rub. (05 Mar 2000) |

| biopsy, pleural needle | <investigation, procedure, surgery> A pleural needle biopsy involves the use of a needle (inserted from the skin) to obtain a small sample of pleural tissue for microscopic analysis. The biopsy is done using a local anaesthetic. Abnormal results may reveal cancer (metastatic or primary), tuberculosis, a fungal disease, viral disease, a parasitic disease or collagen vascular disease. Risks include pneumothorax and internal bleeding. (21 Mar 1998) |
