| bone metastases in kids | <radiology> Rhabdomyosarcoma, neuroblastoma, histiocytosis X Note: Wilms tumour goes to lung, not bone (12 Dec 1998) |
|---|---|
| brain abscess in kids | <radiology> Cyanotic congenital heart disease, e.g., tetralogy of Fallot, most important predisposing factor, blood not filtered by pulmonary capillaries (12 Dec 1998) |
| complex liver mass in kids | <radiology> Epithelial, FNH (uncommon, F greater than M), hepatic adenoma (uncommon, F greater than M), hepatoma (increased aFP in 90%), hepatoblastoma (increased aFP, less than 2 years of age), mesenchymal, hamartoma, cavernous haemangioma, haemangioendothelioma, embryonal rhabdomyosarcoma (obstructs common bile duct; less than 5 years of age), undifferentiated sarcoma, teratoma, abscess / haematoma / complicated cyst (12 Dec 1998) |
| pneumoperitoneum in kids | <radiology> Premature infant: NEC most likely to be perforation, air-block most likely to be dissection of air from mediastinum, full-term infant: idiopathic gastric perforation, older kids: perforated peptic ulcer, rupture of Meckel diver, diseased bowel (12 Dec 1998) |

| advanced life support | Definitive emergency medical care that includes defibrillation, airway management, and use of drugs and medications. Compare: basic life support. (05 Mar 2000) |
| artificial life | Artificial life (AL, alife) is a scientific discipline in whichresearchers study life by creating computer programs that recreatebiological systems from scratch. (09 Oct 1997) |
| basic life support | Emergency cardiopulmonary resuscitation, control of bleeding, treatment of shock, acidosis, and poisoning, stabilization of injuries and wounds, and basic first aid. (05 Mar 2000) |
| biological half-life | <biochemistry, biology> This is the time required for one-half of the total amount of a particular substance in a biological system to be consumed or broken down by biological processes when the rate of removal is approximately exponential. Toxic chemicals with a long biological half-life (such as some pesticides) will tend to accumulate in the body and are, therefore, more likely to be harmful. A substance with a short biological half-life may still accumulate if a portion of it it becomes tightly bound to bone or other tissues, even if most of it is quickly cleared from the body. (21 Mar 1998) |

| RNA life | <biology, molecular biology> A hypothetical life form lacking DNA and protein which may have existed on early earth and in which RNA served both a genetic coding and a catalytic function. (23 Aug 1998) |
| physical half-life | The time required for half the atoms of a radionuclide to undergo disintegration. (05 Mar 2000) |
| wrongful life | In civil law a cause of action which alleges that a defendant has wrongfully caused a child to be born. (12 Dec 1998) |
