[3-6 week old boys]
describe Puberty timeline for females (3)
[8-12 yof: breast + pubic hair]
[–(within 2.5y)–> growth spurt] ->
[MENARCHEby 13y or [by 15y if ⊕F∆]]
1º amenorrhea = NO MENSES by 13y or ([15y if ⊕F∆])*
What does Constitutional Short Stature refer to
“late bloomer” but will attain normal adult height later
pts have normal birth wt and ht but ht velocity slows between 6 mo-3 yo, picks back up after and slows again at adolescence. bone radiographs will show delayed bone age
[Genu Varum] is normal during age ⬜ and presents as (⬜3) . When should this correct by?
0-2 yo ; [BL symmetric bow leg, normal stature, no lateral thrust]
_________________
should correct by 2 yo
[varum is nml 0-2 yo] [ValGus = nml in 4-7 yo]

obtain XR if > 2 yo, short stature or uL
Newborn failure to pass meconium within 48 hours of birth likely indicates ⬜
MOD -5
Hirschsprung Disease
________________
[RET gene mutation vs Trisomy 21] →
failure of neural crest cell migration → absence of ganglion cells from [Auerbach/Meissner enteric nervous plexus] in rectosigmoid (confirmed by rectal suction biopsy)]
= transition zone cutoff between
[narrow aganglionic rectosigmoid] and [markedly dilated innervated descending colon]
EARLY AFTER BIRTH

tx = supportive +/- [Vitamin A if hospitalized]

After successfully treating Acute Otitis Media, how should you manage a patient who p/w persistent middle ear fluid build up?
_________________
Explain why
WATCHFUL WAIT X 3 MO after treatment
_________________
serous fluid may persist in middle ear self-limited to 3 mo after AOM treatment (= [SOME - serous otitis media with effusion] )
further w/u if: infection / BL effusion / sx > 3 mo

Risk factors for Developmental Dysplasia of Hip - 3
________________
when should you stop screening for this?

- Breech Delivery - GET HIP IMAGING IF FEMALE AND BREECHED
- Female - GET HIP IMAGING IF FEMALE AND BREECHED
- Fam hx
12 months old

Dx Criteria for Kawasaki Disease
{[4/5 CRASH] + [Burning HIGH Fever ≥ 5 days]}
- Conjunctivitis
- Rash
- Adenopathy uL in cervical region (least likely)
- Strawberry tongue/oral mucosa changes
-
Hand/Feet redness or swelling
THIS IS DX OF EXCLUSION! THERE CAN NOT BE ANOTHER OBVIOUS CAUSE OF PRESENTATION
Meckel’s Diverticulum etx -4
tx = surgery
👶failure of [pre-gastropancreatic_vitelline duct] to obliterate during first 8 WG
👶 ➜leaves behind RLQ [gastropancreatic ectopic tissue] in blind pouch
👶this blind pouch ectopically produces gastric acid that irritates mucosal lining → mucosal bleeding
👶 ultimately = [NONPAINFUL HEMATOCHEZIA +/- IDA IN 2 YOM]
also could be: asx / [Intussusception] / Diverticulitis / Bowel obstruction
Malrotation and Volvulus are both diagnosed with ⬜
Describe how both would look on this diagnostic?
[UGSBS- Upper GI Series barium swallow]
________________
Malrotation = Ligament of Treitz on the R side of the abd in a gasless abd
________________
Volvulus = corkscrew image

management of
pediatric functional constipation (3)
1st: dietary ∆
2nd: Osmotic Laxatives
ACUTE DISIMPACTION: STIMULANT LAXATIVE
_________________
dietary ∆ = [⇪ fiber/water] | [cow’s milk< 24oz]
How do you manage infants born to Mothers with Active Hepatitis B (4)
_________________
How do you determine if the infant was vertically infected?
infant receives @:
- [BIRTH⼀within 12h of delivery: {obtain[HBV 🅂Ag]🧪1 → administer[HBVIG with HBV💉1]}
_________________ _________________
- [2 mo: HBV💉2]
_________________ _________________
- [6 mo: HBV💉3]
_________________ _________________
- {–(3 months later)–> [9 mo: obtain🧪[HBV 🅂Ag]🧪2 }
_________________
[HBV 🅂Ag] = [HBV “🅂”urface antigen]

[HBV 🅂Ag]
⚠️if [HBV 🅂Ag] positive = HBV VERTICALLY INFECTED!
___________________________x____________________________________
🧪 = labs || 💉=vaccine
Annual Influenza vaccine is recommended for kids age ⬜ for what purpose?
≥6 month old ; prevent [infection and spread of infection] to at-risk populations (asthma/chronic illness/<2 yo)
Hypetrophic Pyloric Stenosis cp (6)
- age 3-6 weeks old
- [POSTPRANDIAL PROJECTILE NONBILIOUS EMESIS]
- [“Hungry Vomiter” (hunger immediately after vomiting)]
- [Epigastric Palpable Olive mass]
- Visible peristalsis
- [hypOchloremic hypOkalemic metabolic alkalosis]

[dx = US] | [tx = IVF ➜ Pyloromyotomy]

FPIAP is a ⬜ reaction to ⬜ that presents in normal infants as ⬜ . The treatment in formula-fed infants is ⬜
FPIAP = Food Protein Induced Allergic Proctocolitis
[non-IgE allergy] ; [milk protein (cow’s milk or soy protein)] ; blood-streaked stools ; Extensively Hydrolyzed Formula

FPIAP = non-IgE rxn to milk protein (casein/whey) = no skin/pulm rxn
Slipped Capital Femoral Epiphysis is a complication of childhood obesity
When does this present?
________________
How does this present?
________________
dx?

puberty (most common hip disorder in fat teens!)
________________
[M: [CHRONIC vague hip/knee pain]
________________
pelvis XRay

“Fat teen Slipped on [ASS, broke Neck] [PIS off Heads]”
[Fat teenchild obesity] during [Slipped Capital Femoral Epiphysis]
–(gradually)– > [ANT SUP Slip femNeck]
which → [POST INF Slip femHead]
➜ [CHRONIC vague hip/knee pain]</sub>
Oligohydramnios –> ⬜ sequence.
Name the 3 most common causes of Oligohydramnios
Oligohydramnios –> POTTER Sequence
POSTERIOR URETHRAL VALVES are the most common cause of obstruction in newborn boys (which causes renal damage –> Oligohydramnios during utero)

What is [Impetigo Diaper Dermatitis]? (3)
________________
Tx? -3
-secondary bacterial diaper infection (by staphA > GASP)
-[PAINFUL honey-crusted papules and pustules]
-in neonates can be c/b sepsis
________________
[: + sepsis s/s]: [Admit for IV Abx and sepsis w/u]
________________
sepsis s/s = [neonatal fever/irritability/lethargy]

Both [Croup Laryngotracheitis] and Epiglottitis cause inspiratory stridor
How do you discern the two?
Epiglottitis causes Drooling!
