70
Where does most of the bilirubin in the newborn come from?
75% comes from the physiological breakdown of RBCs
The hemoglobin released from the red cells is converted to unconjugated bilirubin that is insoluble in aqueous solutions and binds to albuminin the blood stream.In the liver the bilirubin is extracted by the hepatocytes where it binds to cytosolic proteins and is then conjugated with glucuronide by uridinediphosphate glucuronyl transferase (UDPGT, also known as glucuronosyl transferase).The conjugated bilirubin is water-soluble and is excreted into the bile and then into the intestine.
In adults, most of the bile is metabolized by the intestinal flora to urobilin and excreted in the stool. The newborn infant, however, lacks thegastrointestinal flora to metabolize bile, which allows the β-glucuronidase present in the meconium to hydrolyze the conjugated bilirubin back to itsunconjugated form.The unconjugated bilirubin is then reabsorbed into the blood stream where it binds to albumin.Newborns absorb significant quantities of bilirubin through this process, known as enterohepatic circulat
71
Kernicterus
Kernicterus is the pathological term used to describe staining of the basal ganglia and cranial nerve nuclei by bilirubin. "Kernicterus" also describesthe chronic clinical condition that results from the toxic effects of high levels of unconjugated bilirubin.Kernicterus res
72
Physiologic jaundice
This is defined as a total bilirubin level ≤ 15 mg/dL (≤ 257 μmol/L) in full-term infants who are otherwise healthy and have no other demonstrable cause for elevated bilirubin.
Almost all newborn infants have hyperbilirubinemia, but it is benign and self-limited.
Physiologic jaundice in a full-term baby is usually first noticed on the second or third day of life, with the bilirubin level reaching its peak at day three or four of life.
Numerous factors promote the increased enterohepatic circulation that results in physiologic jaundice:
- Increased bilirubin production (from the breakdown of the short-lived fetal red cells)
- Relative deficiency of hepatocyte proteins and UDPGT
- Lack of intestinal flora to metabolize bile
- High levels of β-glucuronidase in meconium
- Minimal oral (enteral) intake in the first 2-4 days of life, resulting in slow excretion of meconium (especially common with breastfed infants)
73
Breastfeeding jaundice
- happens early in the first week of life and occurs when the milk supply is relatively or absolutely low, resulting in limited enteral intake.
- This may be referred to as a "lack-of-breast milk jaundice" or "breastfeeding-associated jaundice."
- The low intake results in decreased gastrointestinal motility that in turn promotes retention of meconium.
- The β-glucuronidase in meconium deconjugates bilirubin and the unconjugated bilirubin is reabsorbed via the enterohepaticcirculation, causing an elevation of serum levels.
- Occasionally, persistently low volume of breast milk can cause the neonate to become dehydrated and malnourished.Breastfeeding jaundice is often difficult to distinguish from physiologic jaundice
74
Breast milk jaundice
- Begins in the first 4 to 7 days of life but may not peak until about 10 to 14 days.
- Not the result of low breast milk volume.
- While the cause is not completely understood, one explanation is that β-glucuronidase present in breast milk deconjugates bilirubin in the intestinal tract; the unconjugated bilirubin is then reabsorbed via enterohepatic circulation.
- Breast milk jaundice can persist for up to 12 weeks, but total bilirubin concentration rarely, if ever, reaches concerning levels.
- The time course of breast milk jaundice is quite different from that of physiologic jaundice
75
Hemolytic causes of jaundice
Antibody-positive hemolysis is labeled "direct Coombs" or "direct antibody test (DAT)" positive.
The most common forms of antibody-positive hemolysis include:
-Rh incompatibility (mother is Rh-negative and baby is Rh-positive)
-ABO incompatibility (mother is type O and baby is type A or B)
-Incompatibilities with minor blood group antigens (much less common)
Antibody-negative hemolysis occurs in infants who have red blood cell membrane defects (e.g., spherocytosis) or red blood cellenzyme defects (glucose-6-phosphate dehydrogenase or pyruvate kinase deficiency).
76
Non-hemolytic RBC breakdown
- excessive bruising from birth trauma
- large cephalohematoma or other hemorrhage (e.g. intracranial)
- polycythemia
- swallowed blood (large amounts) during delivery
77
Metabolic causes of jaundice
Crigler-Najjar syndrome type 1 and type 2: is a rare (1;1,000,000 newborns) autosomal recessive condition that causes severe unconjugated hyperbilirubinemia starting in the first few days of life. It results from decreased bilirubin clearance caused bydeficient (type 2) or completely absent (type 1) UDPGT and can lead to kernicterus.
Gilbert Syndrome is a much less severe but more common cause of unconjugated hyperbilirubinemia than Crigler-Najjaar. The more common form of this condition involves the UGT1A1 gene and is inherited in an autosomal recessive pattern. The resulting decreased enzyme function interferes with glucuronidation and therefore the conjugation of bilirubin is slowed.Patients with Gilbert syndrome have intermittent, self-resolving episodes of unconjugated hyperbilirubinemia, usually beginningin adolescence.
Galactosemia and hypothyroidism also have jaundice as prominent clinical findings. Jaundice found in hypothyroidism may be caused by a combination of decreased rate of bilirubin conjugation, decreased gut motility and impaired feeding. These congenital disorders may be detected by neonatal screening.
78
Typical infant breastfeeding pattern
A successfully breastfed baby typically nurses 8-12 times in 24 hours.
Feedings may initially last up to 60 minutes but gradually become shorter in duration, ~10-15 minutes at each breast. (Increasingly frequent or consistently lengthy feeding sessions may indicate a problem, especially if the infant is not gaining weight.)
79
Biliary atresia
A healthy-appearing infant who develops jaundice, dark urine, and acholic (pale) stools between 3 and 6 weeks of age may have biliary atresia.
Any infant who develops jaundice after two weeks of age must be evaluated with fractionated bilirubin (i.e., total and direct bilirubin levels).
A patient suspected of having biliary atresia generally will be referred to a pediatric gastroenterologist or pediatric surgeon.
Treatment
When diagnosed early, biliary atresia can be treated surgically with the Kasai procedure (anastomosis of the intrahepatic bile ducts to a loop of intestine to allow bile to drain directly into the intestine).
If done early, the Kasai procedure will restore bile flow and prevent liver damage.
80
Caput vs cephalohematoma
A caput succedaneum is an edematous swelling over the presenting portion of the scalp of an infant and is commonly seen in babies born vaginally in vertex position. Because the scalp overlies the periosteum, this boggy swelling crosses suture lines, easily differentiating it from a cephalohematoma.
81
How often should young infants breastfeed?

86
CAH
The most common form of congenital adrenal hyperplasia, 21-OH deficiency, causes decreased production of cortisol and aldosterone.
Plasma 17-OH progesterone is elevated with 21-OH deficiency because its production occurs prior to the block in the pathway of adrenal steroid formation.
The increased 17-OH progesterone with CAH is diverted to androgen formation.Thus, female patients with 21-OH deficiency are virilized.
Male patients with 21-OH deficiency may be harder to detect (virilization presents as increased penile length and darker pigmentation of the scrotum).
Decreased mineralocorticoid activity in 21-OH deficiency (the salt-wasting form) leads to hyponatremia and hyperkalemia, and may present with vomiting, dehydration, and shock in a newborn.
87
Congenital hypothyroidism symptoms
- Feeding problems
- Decreased activity
- Constipation
- Prolonged jaundice
- Skin mottling

With time, if untreated, patients develop a large tongue, hoarse cry and puffy myxedematous facies.
CH is one of the most common preventable causes of intellectual disability. The longer treatment is delayed, the greater the risk
Newborns with a low T4 and elevated TSH on the newborn screen are considered to have CH until proven otherwise.
Because early treatment is critical for normal development, the patient should be started on levothyroxine (L-thyroxine) while waiting forconfirmatory measurement of serum T4 and TSH.

Measles
After a prodrome of fever (over 38.3 C, or 101 F), cough, coryza, and conjunctivitis, this maculopapular rash starts on the neck, behind the ears,and along the hairline.
The rash spreads downward, reaching the feet in two or three days.The initial rash appears on the buccal mucosa as red lesions with bluish whitespots in the center (known as Koplik spots).
These have frequently disappeared by the time the patient presents to medical attention.
Immunization is very effective in preventing this infection.

Which bugs cause pneumonia in which ages?
Most common cause of pneumonia in kids is a respiratory virus (adenovirus, RSV, parainfluenza, influenza)
In the neonatal period, bacteria transmitted from the maternal genital tract must be considered, including Group B streptococcus, E.Coli, and Klebsiella.
Pneumonia due to Chlamydia pneumoniae usually presents with a staccato cough between 4 and 12 weeks of age.
Streptococcus pneumoniae is the most common bacterial cause of pneumonia in the U.S. among infants beyond the neonatal period and children up to 5 or 6 years of age.In school-aged and older children,
Mycoplasma pneumoniae is the predominant cause, followed by S. pneumoniae.
110
Croup

Mostly due to parainfluenza, but can also be due to RSV, influenza, and rhinovirus.
Peak incidence 2y
Cough and stridor: Croup often starts with cold-like symptoms (congestion, coryza, sore throat, cough, and fever). This may progress to inspiratory stridor and a "seal-like" or "barky" cough
CXR: narrowing in the subglottic region ("steeple sign")
Tx: supportive
Breathing humidified air or mist therapy can improve laryngospasm. Racemic aerosolized epinephrine can beused for acute improvement, and oral or IM dexamethasone can reduce the severity of symptoms
111
Foreign body aspiration xray
PA film (with the child in a sitting position): Right hemidiaphragm is flattened, suggesting unilateral hyperexpansion on the right.
Right decubitus: With child on her right side, the mediastinal structures remain in the midline, rather than shifting towards the right lung due to gravity, further demonstrating the fixed hyperinflation of the right lung.
Left decubitus: With child on her left side, the mediastinal structures shift towards the left lung as expected.

Post-infectious cerebellitis
Autoimmune post-viral
occurs several weeks after a viral infection (e.g., varicella or coxsackie virus).
Onset is sudden and consists of ataxia, vomiting, nystagmus in about half of the patients and dysarthria in some.
CSF may be normal or have a pleocytosis; eventually the CSF protein is elevated.
135
Infectious cerebellitis
May be viral or bacterial in etiology.
Fever is often an accompanying symptom.
Mental status changes are often observed.
Examples of pathogens include mumps, enteroviruses and Epstein-Barr virus.
Bacterial pathogens include those that cause bacterial meningitis (e.g., Streptococcus pneumoniae, Neisseria meningitidis and Haemophilus influenzae type B.
136

Bronchopulmonary dysplasia
BPD is a chronic lung disease of premature infants resulting from damage to immature and insufficently flexible alveolar tissue associated with intubation, positive pressure ventilation, and oxygen toxicity.
BPD (or chronic lung disease) may cause poor growth in part due to increased caloric requirements, repeated pulmonaryinfections or congestive heart failure.
Development in these infants may be delayed because of prolonged or repeated hospitalization due to illness, underlying neurological disease, or both.
153
Retinopathy of prematurity
ROP is characterized by extraretinal fibrovascular proliferation and, in severe cases, may cause retinal detachment and blindness.
All premature infants, particularly those weighing less than 1500 g are at risk of ROP.
Approximately 50% of infants weighing less than 1200 g develop ROP.
Development in children with ROP may be delayed depending on the degree of visual impairment
154
Periventricular leukomalacia
PVL is the result of damage to the white matter surrounding the ventricles in the brain as a result of hypoxia, ischemia,and inflammation.
It is correlated with intraventricular hemorrhage (bleeding from the delicate vessels of the neuronal and glial proliferationzone-germinal matrix-that surrounds the lateral ventricles in preterm infants and fetuses); it is likely that damage to the white matter is actually more widespread, but not easily visualized using current clinical imaging techniques.
PVL with cysts (cystic PVL) is highly correlated with cerebral palsy
155
