What investigation would you do next?
ExpiratoryCXR
Inspiratory Expiratory
Foreign Body Aspiration
• Highest risk between 1 -3 yrs old• Immature dentition, poor food control• More common with food than toys
peanuts, grapes, hard candies, sliced hot dogs

Case 6
• What is the degree of dehydration of this child?• Management?
Dehydration
Gastroenteritis
• 10% Dehydration
• Rule out UTI
• ORT with rehydration solution (Pedialyte, Gastrolyte)• 5 ml/kg/hr divided every 5 min• continue until appears hydrated
• Consider Ondansetron (0.15 mg/kg)
• Early refeeding (including milk) within 12 hrs
Fluids and Electrolytes
• Maintenance (D5NS)• 4cc/kg/hr for first 10 kg• 2cc/kg/hr for second 10 kg• 1 cc/kg/hr for rest of weight in kg
• Deficit (NS)• If severely dehydrated give FLUID BOLUS, 20 cc/kg
over 15-60 min • Deficit fluid - first half over 8hrs, second half over
16 hrs
• Ongoing Losses• Diarrhea, vomiting, NG losses, polyuria• Insensible losses with fever
Case 7
15 month old male

• HR130 RR24 T37 • Tender abdomen with fullness in RUQ
• Diagnosis?• Investigations?
Intussusception
• 1-3 years• Boys 2:1
• Classic Triad (10-30%)• Vomiting• Crampy abdominal pain• “Red currant jelly” stools
• Lethargy is common
• 75% are ileo-colic• Lead point - Peyer's Patches - preceding viral
infection• Meckel diverticulum, polyps, hematoma (HSP),
lymphoma
Intussusception
• Plain AXR
• May be normal
• May have signs of bowel obstruction
• Paucity of air in RLQ • No air in Cecum on
Lateral Decubitus
Intussusception
• Target Sign
Intussusception
• Crescent Sign
Intussusception
Intussusception
• Air Contrast Enema
• Success rate >80%• Recurrence 10-15%
Case 8
• 4 week old boy with vomiting for past week.
• Initially one emesis per day now emesis with every feed. Forceful. No bile.
• No fever. No diarrhea.
• Born at 39 weeks gestation. Spontaneous vaginal delivery.
• Looks well. Mild dehydration. • Abdomen soft, non tender, BS present.
• DDx?
Case 8

• WBC 8.5 Hgb 120 Plts 360
• Venous gas pH 7.50, PCO2 44, HCO3 30
Pyloric Stenosis
• Most common surgical condition < 2 mos• 4-6 wks of age• Ratio male to female is 4:1• Increased in first born males• Occurs in 5% of siblings and 25% if mother was
affected
• Symptoms of gastric outlet obstruction• Nonbilious vomiting• Emesis increases in frequency and eventually
becomes projectile
Pyloric Stenosis
• Classically:• Hypertrophied pylorus
palpable “olive” in epigastric area
• Peristaltic waves progressing from LUQ to the epigastrium
• Laboratory abnormalities:• Hypokalemic• Hypochloremic• Metabolic alkalosis
Case 9

• Multiple episodes of yellow green vomiting since this morning.
• Progressive lethargy and irritability. Poor feeding.
• Looks unwell, irritable cry.• Abdomen distended.• Weak pulses, cap refill>5 sec.
• DDx? Management?
Volvulus
• Twisting of a loop of bowel around its mesenteric attachment.
• Sudden onset of bilious vomiting in a neonate.
• Acute abdomen with shockmay have a gradual course with
episodic vomiting
• 80% present by the first month40% present in the first week Rarely can be seen in older
children.
Volvulus• Evidence of small bowel obstruction
dilated loops, air fluid levels, paucity of distal air
Volvulus
• Upper GI series • “corkscrew”
appearance of the duodenum and jejunum
Case 10
1 month old girl
• 12 hr history of fever, decreased feeding
• Looks well, alert and interactive• T 38.9o HR 176 RR 42 BP 100/50 • Font flat, neck supple, exam non remarkable
• What is your approach to this case?
Low Risk Criteria (Rochester) for Febrile Infants• Well appearing infants 1-3 months are low risk for
serious bacterial infection if the following criteria are met:
• Previously healthyBorn at term (> 37 weeks)No hyperbilirubinemiaNo hospitalizations No chronic or underlying diseases
• No evidence of focal bacterial infection• Laboratory parameters:
WBC count 5-15/mm3
Urinalysis WBC count < 5/hpfStool WBC count < 5/hpf (if infant has diarrhea)
Case 11

• T 39.2o HR 110 RR 24 BP 110/60 • Awake now, normal neurological exam• Right TM bulging, neck supple, no rash • Past med history unremarkable
• Approach?
Febrile Seizure
• ABC's, IV access
• Seizure treatment• IV/PR lorazepam or diazepam• phenytoin, phenobarbitol
• Simple Febrile Seizure• T>38.5• <20min, generalized seizure• 6mo-6yr• neurologically normal before and after
• Observe in the ED until child returns to normal neuro status
Case 12

• Bilateral non-purulent conjunctivitis• Polymorphous skin eruption• Changes of peripheral extremities
Initial stage: reddened palms and solesConvalescent stage: desquamation of fingertips and toes
• Changes of lips and oral cavity• Cervical lymphadenopathy ( >1.5 cm)
Kawasaki Disease
• Subacute phase - Days 11-21• Resolving acute symptoms• Desquamation of extremities• Arthritis
• Convalescent phase - > Day 21• 25% develop coronary artery aneurysms • Myocardial infarction
• Other manifestations:• Uveitis• Pericarditis• Hepatitis, Gallbladder hydrops• Sterile pyuria, Aseptic meningitis
Kawasaki Disease
• Investigations:• CBC – thrombocytosis• ESR – elevated• CXR, ECG• Echocardiogram
• Treatment• IV Immunoglobulin
reduces incidence of coronary aneurysms to 3% if given within 10 days of onset of illness
defervescence with 48 hrs• ASA
high dose during acute phase then lower dose for 3 mos
Case 13
• 3 yr old girl with rash starting today
Recent URTI
Swollen ankles and knees. Painful walking.
Diagnosis?

• Systemic vasculitis – IGA mediated• 75% of cases between 2-11 years of age
• Clinical Features 100% - rash (non thrombocytopenic purpura) 68% - arthritis 53% - abdominal pain 38% - nephritis (ESRD in ~1%)
• Intussusception (2-3%)
