    7 y with viral URTI 2 weeks ago. Now presents in CHF and a maculopapular rash. What is the most likely diagnosis?
    a. Viral myocarditis?
    b. Acute rheumatic fever
    c. Subacute bacterial endocarditis
A

Viral myocarditis

Murmur with gallop suggests CHF
CHF is unlikely for ARF

Rash

  • ARF = erythema marginatum
  • SLE = malar + discoid rashes
  • SBE = Osler node, Janeway lesions, splinter hemorrhages

Most common pathogens for viral myocarditis:

  • enteroviruses e.g. coxsackie
  • influenza
  • adeno
  • EBV/CMV
  • parvo

Presentation

  • fever, tachycardia, hypotension, gallop rhythm, murmur, resp distress
  • acute or chronic heart failure or chest pain
  • if decompensated heart failure, then hepatomegaly, peripheral edema, wheeze + rales

Diagnosis

  • Cardiac MRI is standard for Dx!
  • ECG + ECHO: non-specific

Supportive care

  • Inotropes (esp milrinone), use but with caution
  • Diuretics
  • IVIG + steroids are controversial

    a) Ischemic stroke
    b) Confusional migraine
    c) Poisoning
    d) seizure
A

Poisoning
Likely sedative hypnotic

No description of sz. Post-ictal period:

  • usually manifests as confusion + suppressed alertness
  • can have focal neuro deficits that reflect type + location of sz (e.g. Todd paresis = postictal paresis: aphasia, hemanopsia, numbness)
  • lasts from sec to hours
  • most recover responsiveness + alertness within 10-20 min of generalized sz. Gradual + consistent improvement with time

Ischemic stroke
- would expect changes in tone + pupils

Confusional migraine

  • H/A typical of migraine
  • PLUS agitation, disorientation, aphasia that last longer than H/A
  • Duration of confusion 2-24H
54
Q
  1. A child was found with Anti-cholinergic symptoms cause?

Q
  1. Kid took bottle of camphor. What do you see on CXR?
    a. Pneumatocele
    b. Hyperinflation
    c. Cardiomegaly
    d. Tracheal-bronchial narrowing
A

Pneumatocele

Camphor = hydrocarbon
Vicks inhaler, tiger balm

  • early onset of Sx (5-15min post ingestion)
  • oxidized + conjugated by the liver, renally excreted
  • Sx typically resolve within 24H
  • aspiration leading to pneumonitits are most dangerous consequence of acute hydrocarbon ingestion
  • oropharyngeal irritation, N/V, abdo pain, sz
  • transient mild CNS depression

IVx

  • Can detect camphor in blood + urine, but not useful
  • leukocytosis, proteinuria, transient transaminitis
  • ECG
  • CXR: lung changes within 2-8H, peak in 48-72h. Pneumatoceles + pleural effusions can occur 2-3wks after

Tx

  • No gastric emptying (risk of aspiration worse than risk of systemic toxicity)
  • No activated charcoal (hydrocarbon absorbed too quickly for it to be effective)
  • ASx or mild oropharyngeal irritation/GI irritation observe minimum 4H
  • If Sz (highest risk in first 2H0, give benzo
56

AG Metabolic acidosis (d/t accumulation of lactic acid + ketoacid)
Hypokalemia
Hyperglycemia (early on) then hypoglycemia (later on)

Renal failure is rare, but indication for dialysis

Activated charcoal
NaHCo3 to alkalinize urine
Give dextrose
IVF

Check for acetaminophen co-ingestion!

58
Q
  1. Treatment of methanol overdose

a. fomepizole

A

Fomepizole

Methanol

  • 2 step metabolism into formic acid (toxic metabolite)
  • lethal dose 1g/kg
  • AG met acidosis with OG>10
  • OCULAR TOXICITY
  • Afferent pupillary defect = ominous sedation

Tx

  • ABCs
  • Fomepizole: inhibits hepatic oxidation, so elimination shifts to pulmonary + renal routes
  • NaHCO3
  • Folic acid co-factor
  • Hemodialysis if acidemia or visual changes (methanol) or renal failure (ethylene glycol)

Note: ethylene glycol issue is renal failure
Note: isopropyl alcohol hallmark is ketosis without acidosis, no osmolar gap

    a. Supportive
    b. Naloxone
    c. Flumazenil
    d. Atropine
A

Symptomatic management

Dilated pupils
Sympathomimetics
Anticholinergics

Increased HR in both
Flailing arms + legs suggests NM excitation, which is more likely sympathomimetic

  • Naloxone for opioids: Expect miosis (constricted pupils), sedation, decreased HR
  • Atropine for cholinergics: Expect DUMBBELLS. Bradycardia. Constricted pupils.
  • Flumazenil for BZDP = sedative hypnotics: normal/decreased HR, constricted pupils, sedation

    —————-
    A 13-year old boy presents with his parents in an obtunded state. His GCS is 9, he is rousable to stimulation but flails his arms and acts very inappropriately. His is flushed, tachycardic and his pupils are very dilated. What toxin was he most likely to have ingested?
    a. imipramine
    b. jimson weed
    c. alcohol
    d. Morphine
A

Jimson weed = anticholinergic

Dilated pupils + tachycardia

  • sympathomimetics
  • anticholinergic

Opiates: expect constricted pupils, sedation, resp depression, bradycardia

Imipramine = TCA = anticholinergic. TCA would expect hypotension (fluid refractory)

Ethanol = sedative hypnotic = constricted pupils, normal HR, sedation

63
Q
  1. A child ingests some paint thinner which is a hydrocarbon. What should you do in the emergency department?
    a. Gastric lavage
    b. Activated charcoal
    c. Observe and treat supportively
    d. Discharge home
A

Observe + treat supportively

Gastric lavage + activated charcoal is not helpful b/c hydrocarbons are quickly absorbed in the gut

Watch for later effects

    d. Electromechanical dissociation
    —————
    Teenager found in the park. Outside temperature -3 degrees. CPR is provided. What would suggest to you that you can discontinue resuscitation?
    a. benzo found in urine
    b. electromechanical dissociation
    c. refractory ventricular fibrillation
    d. Rectal temp <30oC
    —————
  2. Kid with hypothermia. When would you stop resuscitation?
    a. Electromechanical dissociation
A

Electromechanical dissociation

  • Electromechanical dissociation = PEA can be seen commonly in hypothermia, though more commonly see VF and asystole
  • Benzos in urine: often hypothermia is preceded by other disorders (e.g. drug overdose, alcohol use, or trauma). Should look for and treat these underlying conditions simultaneously with hypothermia Tx
  • Rewarm to T32-34. Rectal temp can often lag behind central temperature measurements. If pt fails to rewarm, use more aggressive rewarming techniques. Treat reversible factors
  • Arrhythmias can resolve once rewarmed. Assuming that pt has core T>32C and still has refractory VF, would consider discontinuining resuscitation. Whereas, if warm and PEA, then still need to go through other Hs&Ts and potentially epi may be more effective once warm

  3. 10 month had private swimming lessons x 45 min. 1 h after lesson is found lethargic and brought to ER. Has GTC Sz. BP 120/80. RR normal. No external signs of head injury. Lungs are clear. What is the most likely etiology.
    a. Chlorine intoxication
    b. Closed head injury
    c. Near drowning
    d. Water intoxication
A

Water intoxication

CPS: swimming lessons for infants/toddlers
Hazards:
1. Drowning
2. Water intoxication with hyponatremia + sz
3. Hypothermia
3. Infections (e.g. otitis externa)

Recommendations

  • <4yo cannot developmentally swim independently, swimming programs in this age is not an effective drowning prevention strategy
  • Residential pools should be fenced on all 4 sides (not including house), include self-closing, self-latching gate
  • PFDs for all young children and those who cannot swim. NOT a substitute for supervision
  • All parents + pool owners should have first aid + CPR training and maintain emergency action plan
81
Q
  1. Child with drowning injury is in PICU on conventional mechanical ventilation, requiring PIP 30 and PEEP 10. He suddenly has an increase in his HR and a drop in his BP to hypotensive levels. What is your next best management?
    a. Increase pip
    b. Decrease pip
    c. Increase peep
    d. Decrease peep
A

Decreases PIP

Could be too high of pressures impeding venous return
But the sudden change suggests obstructive shock from PTX
Positive pressure causes barotrauma
(vs volutrauma = injury due to overdistension of lung during mechanical ventilation)

High PEEP has not been shown to increase risk of barotrauma

Q
  1. 2 month old baby with FTT, constipation, and vomiting. Labs show pH 7.28, Na 128, K 2.7, Cl 107, urine pH 7.5. What is the underlying problem?
    a) CAH
    b) cystinosis
    c) pyloric stenosis
    d) cystic fibrosis
A

??????Cystinosis

Low Na, low K, high chloride
need to know bicarb, but presumably metabolic acidosis

Suggests RTA
urine pH 7.5
Not type IV = hyperkalemic
Proximal RTA = problem with reabsorbing HCO3. If normal kidneys, urine pH <5.5
Distal RTA = failure to acidify the urine. Urine pH >5.5

Pyloric stenosis: expect higher bicarb leading to metabolic alkalosis, low K, low Cl
CAH: expect low Na, high K
Not cystic fibrosis
