List common benign and malignant pediatric neoplasms and contrast sites of involvement. 2 routes of infection: transcervical (ascending/giving birth, transplacental (hematologically) - infectious agents infect the fetus by passing through the placenta. Common infections are: bacteria (e. g. beta hemolytic strep, viral (e. g. herpes) Fetus acquires a transcervical infection either by: Inhaling infected amniotic fluid into lungs, or: acquiring infection when passing through infected birth canal during delivery. Associated with inflammations: chorioamnionitis = inflammation of the placental membrane, funisitis = inflammation of the umbilical cord. Inflammation is a problem for 2 reasons: 1. Inflammatory cells sit on the membrane and cause narrowing of the amniotic sac membrane, which can lead to direct rupture: 2.
