Emma Holiday Review Flashcards
How is intussusception treated?
Both diagnose and treat intussusception w/ barium enema (fluid injected into rectum)
When assessing Moro on LGA newborn r. arm remains extended and medially rotated
LGA = large for gestational age
Erb-Duchenne (Erb’s palsy) C5-C6: brachial plexus injury during birth (typically from shoulder dystocia)
-refer if not better by 3-6 mo for surgical repair
=> waiter’s tip deformity
3 days old, bili at 10, direct at .5, eating and pooping well
Physiologic jaundice
-liver conjugation not yet mature
Describe why babies born to mother w/ GDM are at an increased risk for renal or splenic vein thrombosis
B/c of increased viscosity of blood, polycythemia = increased RBC percent of blood make up
-b/c large babies need more O2, hypoxia stimulates EPO production
Tiny white spots on 2 week old’s nose
= Milia
- keratin filled cysts: can occur at any age but common in newborns
- disappear on own w/in weeks to mo
Tx for TTN
Treating transient tachypnea of the neborn = most common cause of respiratory distress in term neonates
Self-resolves in hours to days, can give supportive O2 but not usually needed
Congenital infxn:
Cataracts, deafness, heart defect, extramedullary hematopoesis
Rubella
2 mo old baby has colicky abd pain and current jelly stool w/ a sausage shaped mass in RUQ
= Intussusception
-part of intestine invagintaes (folds into) another section => obstruction
- Current jelly stool = stool mixed w/ blood and mucus
- sausage shaped mass felt upon palpation = the intussusception
Claw hand in newborn: forearm supinated and wrist/fingers are flexed + Horner’s syndrome
Klumpke’s paralysis: lower brachial plexus (C8-T1) injury
Newborn w/ midline defect w/ no bowel present
(a) Tx
= Umbilical hernia
(a) Doesn’t require repair unless persists past age 2-3
How to treat a 4 day old w/ bilateral purulent conjunctivitis
3-5 DOL w/ bilateral purulent conjuncitivitis = gonococcal conjunctivitis
Tx: topical azithromycin + IV 3rd gen ceph (Ceftriaxone)
Why do mothers w/ gestational diabetes have larger babies?
Mothers w/ gestational DM have increased risk of LGA (large for gestational age)/macrosomia b/c extra blood glucose crosses placental barrier => triggers fetal insulin release
-insulin acts as growth hormone
1 wk old baby w/ bileous vomiting, draws up his legs, has abdominal distention
Malrotation and volvulus
- Malrotation = during development the intestines fail to rotate 270 ccw around the SMA => intestines set into wrong part of the abdomen so they become blocked or twist
- Volvulus = bowel twists on its own blood supply since it is not properly fixed in place, can be fatal if becomes ischemic
What is the danger of untreated gonococcal conjunctivitis?
Untreated gonococcal conjunctivitis can cause corneal ulceration
Why do we care about hyperbilirubinemia (besides that you look yellow…)
Neurological toxic effects of indirect bilirubin
- indirect bili can cross the BBB, despite in the basal ganglia and brainstem and cause kernicterus (bilirubin-induced brain dysfunction)
- esp if bili > 20
Congenital infxn:
Microcephaly, periventricular calcifications, deafness, thrombocytopenia, petechiae
CMV
VACTERL association
VACTERL/VATER association = non-random co-occurence of birth defects
Vertebral, anal atresia, cardiac, radial, renal, limb
Association (not a syndrome) b/c the complications are not pathogenically related, but they attend to occur together
Blotchy red spots with overlying white/yellow papules
= Erythema toxicum
- appears 2-5 days after birth
- harmless, rash generally disappears on own in 2 weeks
Extremely common- up to 1/2 of term newborns
-very distressing to parents but completely harmless
How to treat congenital CMV
Tx congenital CMV w/ ganciclovir, but won’t prevent MR
Newborn w/ defect right of midline w/ no sac
= Gastroschisis
Intestines outside of body b/c of hernia (hole in abdominal wall)
- no sac covering
- surgical repair
How to treat 10 day old baby w/ red conjunctiva w/ mucoid discharge and lid swelling
Tx for chlamydia conjunctivitis = oral azithromycin
Pathophysiology of RDS
RDS (infant respiratory distress syndrome) = premature infants caused by developmental insufficiency of surfactant production and structural immaturity of the lungs
-surfactant = complex substance of lipids and proteins made by type II pneumocytes to prevent collapse of the terminal air-spaces (where alveoli develop) throughout inhale exhale cycle
What tests would you order in a baby w/ > 100.4 F
R/o sepsis
- CBC w/ differential
- CXR
- blood culture
- urine culture (use catheter)
- possibly lumbar picture
Pyloric stenosis
(a) metabolic complication
(b) tx
Pyloric stenosis
(a) Hypochloremic, metabolic alkalosis
(b) Surgery to widen the pylorus
Tx for congenital syphilis
Penicillin
Baby of what age w/ a fever > 100.4 is sepsis until proven otherwise
Baby 100.4 F = sepsis until proven otherwise
Xray finding of necrotizing enterocolitis
Pneumatosis intestinalis = air/gas in the bowel wall
-associated w/ ischemia
Which heart defects are associated w/ congenital rubella
PDA, VSD
Congenital infection:
Hydrocephalus, intracranial calcifications, chorioretinitis
Congenital infxn w/ triad: hydrocephalus, intracranial calcifications + chorioretinitis = toxoplasmosis
Neonatal conjunctivitis on day 7-14
Neonatal conjunctivitis day 7-14 w/ red conjunctiva w/ mucoid discharge and lid swelling = chlamydia conjunctivitis
Which inborn error of metabolism may present w/ jaundice, cataracts, and seizures
Galactosemia
-G1p accumulates to damage kidney, liver, and brain
Tx for congenital rubella
No treatment
Risk factors for necrotizing enterocolitis
- premature gut
- introduction of feeds/formula
Newborn w/ ambiguous genitalia. One month later: vomiting, low Na, high K+, acidosis
= Congenital adrenal hyperplasia = 21 hydroxylase deficiency = deficient production of hormones by adrenal gland
What are 2 major worrisome complications of meconium aspiration syndrome
Pulmonary artery HTN, pneumonitis
38 week LGA infant born by C/S to an A2GDM has dyspnea/grunting
TTN - transient tachypnea of the newborn
-tachypnea ( > 40-60 of newborn) w/in 1-2 hours after birth due to retention of lung fluid
Risk factors: babies who were
- born before 28 weeks
- born by C section
- born to mothers w/ diabetes
Normal RR for newborn- 1 yr old
Under 1 yoa: normal RR 30-40 breaths per minute
Which GU d/o is associated w/ prune belly syndrome
Prune belly syndrome = congenital absence of abdominal muscles
-associated w/ cryptorchidism (teste(s) not in scrotum)
Why are babies born to mothers w/ GDM are at an increased risk for jaundice
Big babies have more RBCs => have more RBCs to break down => increased risk for kernicterus (bilirubin induced brain damage)
Why is diaphragmatic hernia so dangerous in a newborn?
(a) What can be done if dx prenatally
(b) Tx?
Pulmonary hypoplasia
(a) Dx prenatally: plan delivery at center w/ ECMO (extracorporeal life support)- respiratory support device
(b) Let lungs mature 3-4 days then do surgical repair
Congenital infection:
Maculopapular rash on palms and soles, snuffles, periostitis
Congenital infection
-Maculopapular rash on palms and soles, snuffles, periostititis = Syphilis
1 day old, bili at 14, direct is .5
Possibly pathologic jaundice b/c bili > 12.
