| percutaneous umbilical blood sampling | See: PUBS. (12 Dec 1998) |
| nephrostomy, percutaneous | The insertion of a catheter through the skin and body wall into the kidney pelvis, mainly to provide urine drainage where the ureter is not functional. It is used also to remove or dissolve renal calculi and to diagnose ureteral obstruction. (12 Dec 1998) |
| diskectomy, percutaneous | Percutaneous excision of a herniated or displaced intervertebral disk by posterolateral approach, always remaining outside the spinal canal. Percutaneous nucleotomy was first described by hijikata in japan in 1975. In 1985 onik introduced automated percutaneous nucleotomy which consists in percutaneous aspiration of the nucleus pulposus. It is carried out under local anaesthesia, thus reducing the surgical insult and requiring brief hospitalization, often performed on an outpatient basis. It appears to be a well-tolerated alternative to surgical diskectomy and chymopapain nucleolysis. (12 Dec 1998) |
| absolute risk | <statistics> The excess risk due to exposure to a specific hazard (disease, injury, etc.) (15 Jan 1998) |
| acceptable risk | <statistics> This relates to the potential for suffering disease or injury that will be tolerated by an individual, group, or society in exchange for the benefits of using a substance or process that will cause such disease or injury. Acceptability of risk depends on scientific data, social, economic, and political factors, and on the perceived benefits arising from a chemical or process that creates the risk in question. (15 Jan 1998) |
| attributable risk | The rate of a disease or other outcome in exposed individuals that can be attributed to the exposure. (05 Mar 2000) |
| cardiac risk | A term to describe overall risk of developing heart disease (blockage of the coronary arteries). Typical risk factors include: diabetes, high blood pressure, prior heart attack, high cholesterol, obesity, smoking and a family history for heart attacks in parents or siblings. (27 Sep 1997) |
| recurrence risk | In medical genetics, the recurrence risk is the chance that a genetic (inherited) disease present in the family will recur in that family and affect another person (or persons). It is the chance of lightning striking twice (or thrice, etc.). (12 Dec 1998) |
| glaucoma, risk factors | If you belong to a high-risk group for glaucoma, have your eyes examined through dilated pupils every 2 years by an eye care professional. High-risk groups include everyone with a family history of glaucoma, everyone over the age of 60 and any Black over the age of 40. (Among Blacks, studies show that glaucoma is: 5 times more likely to occur in Blacks than in Whites and about 4 times more likely to cause blindness in Blacks than in Whites). (12 Dec 1998) |
| relative risk | <epidemiology> The proportion of diseased people amongst those exposed to the relevant risk factor divided by the proportion of diseased people amongst those not exposed to the risk factor. This should be used in those cohort studies where those with and without disease are followed to observe which individuals become diseased. (05 Dec 1998) |
| risk | The probability that an event will occur. It encompasses a variety of measures of the probability of a generally unfavorable outcome. (12 Dec 1998) |
| risk assessment | The qualitative or quantitative estimation of the likelihood of adverse effects that may result from exposure to specified health hazards or from the absence of beneficial influences. (12 Dec 1998) |
| risk benefit | An analysis of risk versus benefit is a complex assessment that must be made by a physician prior to the administration of a particular form of drug therapy. Since many medications may have side effects that can be harmful (during the course of treatment), the overall risk of a particular form of drug therapy must be weighed against the overall threat of the untreated disease process (or treatment with an altenative drug). (27 Sep 1997) |
| risk factor | <statistics> A clearly defined occurrence or characteristic that has been associated with the increased rate of a subsequently occurring disease. (14 Oct 1997) |
