The article deals with paediatric pathology, which is quite different than adult pathology. Many diseases that afflict children are uncommon or unheard of in adults.
Persistent pulmonary hypertension of the newborn
- Abbreviated PPHN.
- Related to patent ductus arteriosus and persistent fetal circulation.[1]
Associations:[2]
- Meconium aspiration.
- Anemia.
- Infection.
- Pneumonia (severe).
- Hypoglycemia.
- Birth asphyxia.
Hypoxic-ischemic encephalopathy
Main article: Neuropathology
- Abbreviated HIE.
- Autopsy adds some information.
- Two-tone liver - suggests prior injury.[3]
- HIE in perinatal period may be unique to the specific time of the injury, i.e. the type of hypoxic insults vary by developmental stage.[4]
- Some hypoxic injuries that are prenatal do not occur after birth.
- Hypoxic-ischemic insults are predominantly in the white matter.
Germinal matrix hemorrhage
- Arises from the germinal matrix, the tissue from which neurons and glial arise from.[5]
- Location: periventricular; may cause an intraventricular hemorrhage.
- Image: Germinal matrix (nlm.nih.gov).[5]
- Location: periventricular; may cause an intraventricular hemorrhage.
- The germinal matrix is thought to be intrinsically fragile and is especially so in premature infants.
