28
Uncircumcised risk

29
Hearing screening
in first 48 hours
30
otoacoustic emission
OAE, screening for hearing, sounds presented to ear canal and microphone measures response in ear canal
31
auditory brainstem response
screening for hearing loss, ABR, sounds presented and surface electrodes measure brainstem activity
32
Before discharge - parent care
umbilical cord, cricumcision, feeding, bathing, sleeping patterns and positions, car seats, safety
33
Call if baby has...
fever > 100.4F, respiratory distress, irritability, lethargy, decreased feeding, dehydration
34
Preterm birth risk factors - maternal
preeclampsia, drug abuse (cocaine), chronic medical condition, infection
35
preterm birth risk factors - fetal
multiple gestation, premature rupture of membranes, placenta previa, fetal distress
36
Viability limits
22-25 weeks, 400-750 grams, use new ballard
37
common problems in prematurity
temperature instability, apnea, bradycardia, feeding issues - fluids, electrolytes, nutrition - protein, fat, carbs, aa, vitamins, minerals
38
erythema toxicum
very common in newborns, erythematus macules and papules that evolved into pustules, look like flee bites, face, truck and extremities but no palms or soles, self-limited, no tx
39
cutis marmorata
reticulated mottling of skin, symmetric on trunk and extremities, vascular response to cold, resolves with warmed skin, no tx needed
40
harlequin phenomenon
newborn lies on side and erythema on one side with blanching on the contralateral side, develops suddenly and persists for a time, no tx needed
41
transient neonatal pustular melanosis
vesiculopustular rash, more common in black newborns, no erythema, lesions rupture and leave a scaly, pigmented macule (Ddx), entire body can be affected
42
acne neonatorum
closed comedones on forehead, nose and cheeks, can be open comedones, papules and pustules too, sebaceous gland stimulation from infant or maternal androgens, resolve spontaneously within4 months, can tx if longer than 4 months or extensive with benzoyl peroxide, severe/unrelenting - hyperandrogenism?
43
milia
1-2 mm pearly white or yellow papules due to retention of keratin within dermis, forehead, cheeks, nose and chin, spontaneously resolve, self-limited
44
miliaria
sweat retention due to partial closure of eccrine structures, 1-2 mm vesicles without erythema on head,neck, and truck, vesicle ruptures and desquamates, avoid overheating, remove excess clothing, air conditioning, self-limited and benign
45
seborrheic dermatitis
cradle cap - scalp, face,ears, neck, erythema and greasy scales, can spread to diaper, self-limited in most children, scales can be removes with a brush after shampooing followed by tar shampoos if needed
46
congenital melanocytic nevi
dirupted migration of melanocytes precursors in neural crest, brown to balck - flat or raised, potential for melanoma in a small % of kids, removal if large or changes in color, shape or thickness with regular followup
47
dermal melanosis
mongolian spots, flat bluish-gray brown lesions from trapped melanocytes, back or buttocks and lock like bruises, make sure to document, self-limited and fade by 2 years of age
48
hemangiomas
strawberry in infants, most involute and disappear by 10 years old (90%), may leave atrophy, telangiectasias, hypopigmentation or scars, can tx if getting near school age, tx if near orifice with prednisone, multiple - look for them in liver and GI tract too
49
nevus flammeus
port-wine stain, vascular birthmark, dark red to purple, do not fade ofer time, don't require tx but can use laser to lighten , if near opthalmic distribution of trigeminal nerve watch for glaucoma - Sturge-Weber syndrome
50
nevus simplex
salmon patch, stork bites, angel kisses, flat salmon-colored lesions caused by telangiectasias in dermis, blanch readily, symmetric, benign and resolve
51
skin markers of spinal dysraphism
incomplete fusion of midline elements of the spine, midline lumbosacral skin lesions - lipomas, dimples, dermal sinuses, tails, hemangiomas, etc are cutaneous markers - image (MRI or ultrasound) to check especially with 2+ lesions at midline
52
cafe-au-lait spots
coffee with milk, normal is small
53
sucking blister
suck in utero, self-limited
54
lanugo
fine hair that will slough off, common with preterm babies
55
intraventricular hemorrhage
occurs in gelatinous subependymal germinal matrix of the premature infant, predisposed - premature, RDS, hypoxic-ischemic inury, incr. or decr. cerabral blood flow, hypovolemia
56
retinopathy of prematurity
retinal vessel development interrupted and restarted causing scar tissue beyond the plane of retina, risk - hyperoxia, extreme prematurity, can cause cataracts, glaucoma, and blindness
57
Respiratory Distress Syndrome (RDS)
hyaline membrane disease, caused by surfactant deficiency - not produced by fetal lungs until 26-28 weeks, develop tachypnea, grunting, retractions, nasal flaring, cyanosis, tx- intubate, oxygen, surfactant, complications - bronchopulmonary dysplasia (chronic lung disease) or oxygen toxicity
58
Group B Strep Infection
Major cause of sepsis in newborns, moms screened at 35-57 wks gestation and given intrapartum antibiotics if needed, signs in neonate - respiratory distress, apnea, bradycardia, hypoglycemia, fever/hypothermia, lethargy, meningitis, if any symptoms - evaluate and empiric therapy
59
Transient tachypnea of the newborn (TTN)
term and pre-term infants can get this, risk with C-section, fetal lung fluid retention, tachypnea, grunting, nasal flaring, retractions with clear lungs, CXR: hyperinflated, prominent vascular markings, spontaneously resolves in 48-72 hours and has no long-term complications
60
hyperbilirubinemia
jaundice in the first 24 hours of life is pathologic, physiologic - breakdown fetal RBCs and decreased bilirubin clearance, may be affected due to breast-feeding - lower fluid vol and frequency of stool or breastmilk - fatty acid impede bilirubin clearance, visible if >7 mg/dl, treat with phototherapy at >15, >20 risk for kernicterus, tx with ad-lib feedings and supplement with formula if needed, exchange transfusion at critical levels
61
Premie discharge criteria
no recent apnea or bradycardia, feed via breast or bottle, maintain temp, steady wt gain, medical conditions stable and clear follow-up plan
62
long-term complications of preterm birth
physical - ROP/visual, sensorineural hearing loss, smaller and shorter though may catch up by 2nd year, higher mortality rate at <2 years of age, risk for developmental delay, mental retardation, or cerebral palsy
