:Myocardial infarction is necrosis of myocardial tissue which occurs as a result of a deprivation of blood supply, and thus oxygen, to the heart tissue. Blockage of blood supply to the myocardium is caused by occlusion of a coronary artery.

;jaundice
;icterus
:Hyperbilirubinemia making Jaundice (or icterus) is a state of hyperbilirubinemia (increased bilirubin in the patient appear blood) in which bile pigment is deposited in the skin, mucous membranes, and scleras. This deposition of bile pigment results in a yellow. Also called jaundiceappearance.

In lieu of cultures, a more rapid diagnostic test is the PPD--purified protein derivative of tuberculosis--test. PPD is injected under the skin of an individual and then the area is reexamined in 48-72 hours for signs of an inflammatory reaction. A positive test indicates previous exposure to M. tuberculosis.

;dissecting aortic aneurysm
:A dissecting aortic aneurysm occurs when an intimal tear allows blood--under very high pressure--to enter the media and thus to separate the intima from the adventitia. The separation occurs longitudinally and amounts to the formation of a blood-filled canal parallel to the aortic lumen which may run the entire length of the aorta. The word "aneurysm" usually refers to an abnormal dilatation of a localized segment of artery. Since marked dilatation of the aorta is not a prominent feature of a dissecting lesion, "aortic dissection" is now the preferred term.

;Rh-positive
:Rh-positive infants of Rh-negative mothers are at particular risk of developing erythroblastosis fetalis (hemolytic disease of newborns) unless preventive treatments are administered. Successful screening for maternal Rh-negativity and subsequent preventive treatment has greatly reduced the incidence of Rh-induced erythroblastosis fetalis. However, ABO incompatibility between the mother and fetus can also cause erythroblastosis fetalis. Thus, the fact that this mother was Rh-positive does not protect the fetus from developing ABO-induced incompatibility if the mother and fetus have different ABO blood types.
;Gravida 2 Para 1011
:Gravida and para are forms of Latin words which are used in clinical notation. Gravida indicates the number of pregnancies which a woman has had (including a current pregnancy). Thus a pregnant woman with two previous pregnancies (regardless of the outcomes of the pregnancies) would be considered Gravida 3 (abbreviated G3). Para indicates the outcomes of a woman's pregnancies. It is represented by four numbers. First number: term births. Second number: preterm births. Third number: abortions. Fourth number: living children. A woman who is currently pregnant and who has had two previous pregnancies--one child being born preterm and the other term, both now living--would be listed as G3 P1102. A current pregnancy is not included because the outcome is not yet known.
;21 weeks gestation
:The normal gestation period is 38 to 42 weeks.
;alpha-fetoprotein
:Alpha-fetoprotein (AFP) is a serum glycoprotein produced during pregnancy by the yolk sac, fetal GI tract, and fetal liver. Elevated serum AFP levels in a pregnant woman can be an indication of a fetal neural tube defect (or something as common as multiple pregnancy). Open fetal neural tube defects allow alpha-fetoprotein to leak into the amniotic fluid, from which it crosses the placenta and enters the maternal bloodstream. Elevated maternal AFP is an indication for amniocentesis (of which an AFP level of amniotic fluid is routine) and an ultrasound. The combination of these two tests are very reliable in detecting neural tube defects.
;4.2 times the mean
:A maternal serum AFP level is considered elevated if it is greater than 2.5 times the mean.
;neural tube defect
:The neural plate is a part of the dorsal ectoderm from which the central nervous system develops. During fetal development, this plate folds longitudinally to form the neural tube which is protected by the eventual development of surrounding mesoderm into the skull, vertebral column, and skin. A neural tube defect occurs when this surrounding mesoderm does not properly enclose around the neural tube.
;amniocentesis
:Amniocentesis is a procedure in which a needle is inserted transabdominally through the uterus, into the amniotic sac, and amniotic fluid is withdrawn.
;465-gram
:A normal male fetus at this age of development should weigh 360 to 492 grams.
; myelomeningocele
:A myelomeningocele is the herniation of the spinal cord--within the meninges--through a defect in the vertebral canal.
;30 mg/dL
:A normal bilirubin level for a child this age would be <2 mg/dL.
; intraoperative cholangiogram
:Transhepatic cholangiography involves the injection of a radiopaque dye into the intrahepatic ducts of patients with obstructive jaundice. Radiographs are then taken to determine whether a route exists for the dye to leave the liver.
;jejunohepatostomy
:A jejunohepatostomy is a procedure in which an attempt is made to bypass the biliary tree by having bile drain into the jejunum. Risks of this procedure include the development of bacterial infections of the intrahepatic biliary tree.
;liver transplant
:Liver transplantation (along with the donor's bile ducts) is the most successful treatment for these patients.
;pre-term
:Births occurring at 38 to 42 weeks of gestation are considered term pregnancies. Anytime earlier are considered pre-term.
;appropriate for gestational age
:Appropriate for gestational age (AGA) is a term which means that an infant's weight and height were appropriate when adjusted for the gestational age of the child. Large for gestational age (LGA) and small for gestational age (SGA) are the alternative designations.
;2550 grams
:The normal weight for a child of this gestational age would be 2250 to 3000 grams.
;cyanosis
:Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from increased concentrations of reduced hemoglobin in the blood. Cyanosis occurs when the blood oxygen saturation falls below 85%.
;respiratory distress syndrome
:Respiratory distress syndrome (or hyaline membrane disease) is a common complication of prematurity, though it can also be seen in term births. The syndrome results from the functional immaturity of the neonatal lung. The syndrome usually presents within one hour of birth and is initially exhibited clinically by rapid respirations, grunting, and substernal retractions.
;pH 7.31
:A normal pH for a child this age would be 7.37.
;PaCO2 35
:A normal level for a child this age would be 33.
;PaO2 35
:A normal level for a child this age would be 90.
;bradycardia
:Bradycardia is defined as a heart rate below 60 beats per minute. A normal heart rate for a neonate is 100 to 160 beats per minute.
;intravenous pyelogram
:An IVP uses contrast dye to produce radiographs of the pelvicaliceal system.
;550-gram
:A normal kidney for a child this age should weigh 50 grams.
;meconium staining
:Meconium is a dark-green mucilaginous mixture of intestinal secretions and amniotic fluid which is found in the intestine of a full-term fetus. Meconium-stained amniotic fluid, found at delivery, may be an indication of perinatal asphyxia.
;meconium ileus
:Meconium ileus occurs when abnormally viscid meconium completely obstructs the ileum of a newborn.
;atelectasis
:Atelectasis is the collapse of an airway and lung, regardless of the cause, resulting in reduced or absent gas exchange.
;pneumothorax
:A pneumothorax is an accumulation of gas in the pleural space.
