A 16 year old girl comes in by ambulance, after fainting while singing at church on a Sunday morning. Her vitals are: HR 90, RR 16, Temp 36.5, BP 92/64. O2 Sat 99% on RA. On arrival she is alert and looks well. She explains that she stood up to sing, felt lightheaded and then, soon after, lost consciousness. The paramedic lets you know witnesses say she turned ashen grey and sweaty, and was out for about 2 minutes. She had some ‘seizure like activity for 10 seconds’ with a few twitches in different parts of her body. The patient states she was fully recovered within a few minutes. Family history is unremarkable, with no sudden early deaths. Physical examination is also unremarkable. The nurse rolls in an ECG machine to check her rhythm.
What investigations does she require?
Why It Matters?
Pediatric syncope is very common in the emergency setting, accounting for ~1 % of pediatric emergency visits. Between 15 and 50% of children will have at least one syncopal event in their childhood (peaking in adolescence). – It’s a common problem!
The problem?
Historically, working up pediatric syncope has varied widely. ECG use has been routine and some centers have regularly ordered bloodwork, CTs and even EEGs. This onslaught of testing has led to increased hospital costs, stressful false positives for patients and has not improved patient outcomes. Plus, reading pediatric ECGs can be challenging – see the end of this pearl.
A potential solution
In 2017, the Canadian Cardiovascular Society and Canadian Pediatric Cardiology Association published a position statement on an approach to pediatric syncope¹ Full Article – click here
A thorough history and physical can be sufficient in low risk patients – no investigations are required for many pediatric syncope presentations.
Red flags
Lack of Prodrome: warm/clammy sensation, lightheaded ness, visual changes. Having a prodrome is the most important factor in benign syncope
Midexertional syncope; however post exertional syncope (having an opportunity to stop) is typically benign
Chest Pain preceding the event
Prolonged loss of consciousness
Family history of cardiovascular disease/sudden death
Palpitations are common in vasovagal events (although evidence around this not robust)
Involuntary movement is also common in vasovagal syncope. Benign movements can be a muscle twitch to violent jerks of the whole body
Investigative Algorithm

The Evidence
To create this position statement, the Canadian Cardiovascular Society (CCS) performed a literature review of 4307 references, ultimately including 231 articles for full-text review.
Most of the studies referred to in the article are retrospective reviews. Therefore, recommendations in the position statement were mostly graded as ‘Strong recommendation, low level of evidence’. I found the most compelling evidence against routine ECG was the statement: “The ECG was the only indicator of cardiac disease in 5 of 480 patients (1%) and causality could not be determined”.¹ However, they did not list a reference for this statement and I’m not sure what study they drew this conclusion from. I do feel they make a compelling case against over investigation, but as in many areas of medicine, the evidence could be more robust.
Pediatric ECGs – how to interpret?
The nurse hands you the ECG, what features are worrisome on a pediatric ECG?
See following chart from the CCS¹
Figure 2. Pediatric ECG findings in syncope, adapted from Sanatani et al. (2017)
In summary, red light features should prompt an emergent cardiology referral. Yellow light features should prompt a non-urgent cardiology referral while green light features are normal variants and require no further work up.
Case Resolution
There were no red flags, arguably she requires no investigations, not even an ECG. Of course, clinical acumen trumps guidelines, but at least you will be CCS endorsed if you chose to not do any further investigations.

Urine is routinely analyzed and cultured as part of a sick child workup, as diagnosis of urinary tract infection can be difficult in pre-verbal children. They are unable to “point where it hurts”, and physical exam can be both difficult and unreliable in an irritable or obtunded infant. Urine may be collected in three ways – by “clean catch” collection, transurethral catheterization (TUC), and suprapubic aspiration (SPA). Given the inherent risk of contamination with local flora (over 25% in one cohort study)1, clean catch urine is typically useful only for ruling out UTI. TUC is more commonly performed as it does not require physician participation, but SPA remains a valid option for obtaining a urine sample for analysis and culture in children under the age of 2. It has been shown to have a significantly lower rate of contamination than TUC (1% versus 12%, respectively)1, although failure rates are higher with SPA4. Use of portable ultrasound has been shown to significantly increase the rate of success of SPA (79% US guided vs 52% blind)5.

Contraindications: 2,3
Genitourinary abnormalities (congenital or acquired)
Empty or unidentifiable bladder
Bladder tumor
Lower abdominal scarring
Overlying infection
Bleeding disorders
Organomegaly
Complications: 2,3
Gross hematuria

Sterile 5ml and 10ml syringes
Procedure (ultrasound-guided): 2,3
Position the patient supine in frog-leg position, using parent or caregiver to assist with immobilization.
Using sterile technique, identify the bladder on ultrasound; it appears as an anechoic ovoid structure just below the abdominal musculature.
Landmarking: midline lower abdomen, just above the pubic symphysis
Mark the area and sterilize; infiltrate local anesthetic into the marked area
Insert the needle slightly cephalad, 10-20° off perpendicular while aspirating until urine appears.
If the insertion is unsuccessful, do not withdraw the needle fully. Instead, pull back until the needle tip rests in the subcutaneous tissue and then redirect 10° in either direction. Do not attempt more than 3 times.
One sufficient urine is obtained, withdraw the needle and place a sterile dressing at the site of the insertion.

Sudden onset language impairment should be assumed to be aphasia until proven otherwise
Aphasia is most commonly caused by CVA and usually has associated lateralising motor signs (but not always)
Aphasic patients will be able to perform non-verbal tasks normally
If in doubt involve telestroke / neurology early
Global aphasia can have a catastrophic outcome on quality of life. In selected patients, early thrombolysis can significantly improve prognosis.
The injuries sustained by children in chest trauma are frequently different from adults
Signs of shock in pediatric trauma can be subtle
Use evidence based guidelines e.g PECARN when considering CT for abdominal trauma
Elevated Tropinin or abnormal ECG suggest blunt cardiac injury
Incomprehensible Patient – Delirium or Aphasia?
Both can present with disorders of speech and language, however it is important to rapidly distinguish aphasia due to it’s association with stroke and the benefits of early thrombolysis.
Delirium, also known as acute confusional state, is an organically caused decline from a previously baseline level of mental function. It often has a fluctuating course, attentional deficits, and disorganization of behaviour including speech and language.
Aphasia is an impairment of language, affecting the production or comprehension of speech and the ability to read or write. Aphasia is always due to injury to the brain, most commonly from a stroke, but also trauma, tumour or infection.
The first tip here is to figure out how to describe the features of a patient’s language. How is the patient’s language produced and understood?
Are the words clearly enunciated (favoring aphasia) or slurred (favoring delirium)?
Is the patient’s speech grammatically correct (delirium) or lacking in appropriate syntax (aphasia)?
Is the patient’s prosody—or pattern of speech—fluent (delirium) or irregular (aphasia)?
Can the patient understand spoken language (delirium) or is there a major difficulty with following simple verbal/written commands (aphasia)?
Naming and repetition should also be assessed as part of any neurologic examination, but impairment in these modalities is not as useful in distinguishing delirium from aphasia.
The motor evaluation of inattention in a delirious patient involves testing for asterixis, either with arms and wrists fully extended or having the patient squeeze the fingers of the examiner (the “milk maid’s sign”). A delirious patient will struggle with these tasks, the extended hands may flap or the fingers may intermittently lose their grip. The aphasic patient, in contrast, may not have trouble with this.
Severe impairment of production, comprehension and repetition of language
Usually large CVA of left MCA
Usually associated with extensive perisylvian injury affecting both Broca’s and Wernicke’s areas
Usually accompanied by right hemiparesis and often a right visual field deficit (in right handed pt)
Patients with global aphasia can be shown to perform normally on nonverbal tasks such as picture matching, demonstrating they are not suffering from confusion or dementia
Stroke Thrombolysis – Indications and Contraindications Reminder
Patient Selection for Thrombolytic Therapy in AIS:
Inclusion criteria: Patients >18 years of age with symptoms of AIS and a measurable neurological deficit with time of onset <4.5 h.
Exclusion criteria:
A. History
History of intracranial hemorrhage
Stroke, serious head injury or spinal trauma in the preceding 3 months
Recent major surgery, such as cardiac, thoracic, abdominal, or orthopedic in previous 14 days
Arterial puncture at a non-compressible site in the previous 7 days
Any other condition that could increase the risk of hemorrhage after rt-PA administration
B. Clinical
Symptoms suggestive of subarachnoid hemorrhage
Stroke symptoms due to another non-ischemic acute neurological condition such as seizure with post-ictal Todd’s paralysis or focal neurological signs due to severe hypo- or hyperglycemia
Hypertension refractory to antihypertensives such that target blood pressure <185/110 cannot be achieved
Suspected endocarditis
C. Laboratory
Blood glucose concentration below 2.7 mmol/L or above 22.2 mmol/L
Elevated activated partial-thromboplastin time (aPTT)
International Normalized Ratio (INR) greater than 1.7
Platelet count <100 x 109/L
Current use of direct thrombin inhibitors or direct factor Xa inhibitors with elevated insensitive global coagulation tests (aPTT for dabigatran, INR for rivaroxaban) or a quantitative test of drug activity (Hemoclot® for dabigatran, specific anti-factor Xa activity assays for rivaroxaban, apixaban and edoxaban). In this situation, endovascular treatment (thrombectomy) should be considered if patient eligible.
D. CT or MRI Findings
Any hemorrhage on brain CT or MRI
CT showing early signs of extensive infarction (hypodensity more 1/3 of cerebral hemisphere), or a score of less than 5 on the Alberta Stroke Program Early CT Score [ASPECTS], or MRI showing an infarct volume greater than 150 cc on diffusion-weighted imaging.
Relative contraindications for rt-PA therapy in AIS include the following:
Recent myocardial infarction with suspected pericarditis
Rapidly improving stroke symptoms
Pregnancy or post-partum period
Recent GI or urinary tract hemorrhage (within 21 days)
Sudden onset language impairment should be assumed to be aphasia until proven otherwise
Aphasia is most commonly caused by CVA and usually has associated lateralising motor signs (but not always)
Aphasic patients will be able to perform non-verbal tasks normally
If in doubt involve telestroke / neurology early
Global aphasia can have a catastrophic outcome on quality of life. In selected patients, early thrombolysis can significantly improve prognosis.
Pediatric Trauma
Some specific issues particular to pediatric trauma are highlighted:
Pediatric Chest Trauma
Children have compliant chests and thus sustain musculoskeletal thoracic injuries far less frequently (5% of traumas). However, due to this elasticity, the most common injury is a pulmonary contusion.
PITFALLS
Don’t expect traditional adult injury findings: Absence of chest tenderness, crepitus and flail chests does not preclude injury.
Bendy ribs – injury to internal organs with little external evidence
Lung contusions ~50% of chest trauma
Force transmitted to lung parenchyma – lung lacerations much less common <2%
Pediatric Abdominal Trauma
Beware: 20-30% of pediatric trauma patients with a “normal” abdominal exam will have significant abdominal injuries on imaging.
Any polytrauma patient with hemodynamic instability should be considered to have a serious abdominal injury until proven otherwise. Tachycardia primary reflex for kids in response to hypovolemia and it may be the only sign of shock.
HIGH RISK – Indications for CT
• History that suggests severe intra-abdominal injury e.g abrupt acceleration/deceleration, pedestrian vs vehicle, handlebar injury, fall from horse etc
• Concerning physical – tenderness, peritoneal signs, seatbelt sign or other bruising
• AST >200 or ALT >125
• Decreasing Hb or Hct
• Gross hematuria
• Positive FAST
PECARN
The Pediatric Emergency Care Applied Research Network (PECARN) network derived a clinical prediction rule to identify children (median age, 11 years) with acute blunt torso trauma at very low risk for having intra-abdominal injuries (IAIs) that require acute intervention.
The prediction rule consisted of (in descending order of importance)
no evidence of abdominal wall trauma or seat belt sign
Glasgow Coma Scale score greater than 13
no abdominal tenderness
no evidence of thoracic wall trauma
no complaints of abdominal pain
no decreased breath sounds
no vomiting
The rule had a negative predictive value of 5,028 of 5,034 (99.9%; 95% confidence interval [CI] 99.7% to 100%), sensitivity of 197 of 203 (97%; 95% CI 94% to 99%), specificity of 5,028 of 11,841 (42.5%; 95% CI 41.6% to 43.4%), and negative likelihood ratio of 0.07 (95% CI 0.03 to 0.15).
The clinical presentation of blunt cardiac injury varies. Mild injuries may present without objective findings, while some patients may have minor dysrhythmias.
A normal ECG and troponin I during the first 8 hours of hospital stay rules out blunt cardiac injury, and the negative predictive value of combining these 2 simple tests was 100%. https://www.ncbi.nlm.nih.gov/pubmed/12544898

Traumatic Tricuspid Injuries
Location, location, location
RV posterior to sternum – blunt force elevates pressures resulting in rupture of chordae, papillary muscle injury or tear of leaflet
Most frequent associated injury: pulmonary contusion
“The presence of a transient right bundle branch block in the setting of myocardial contusion is a described, but under-recognized occurrence.”
“Although an rsr’ in the right precordial leads may be normal in children, it’s combination with an abnormal frontal axis (“bifasicular block”) is always abnormal and suggest injury to the RV”
The injuries sustained by children in chest trauma are frequently different from adults
Signs of shock in pediatric trauma can be subtle
Use evidence based guidelines e.g PECARN when considering CT for abdominal trauma
Elevated Tropinin or abnormal ECG suggest blunt cardiac injury

Question 1 of 6
1. Question
Which of the following features suggests aphasia over confusion?
Correct
Certain features of a patient’s language can be helpful in differentiating confusion/delerium from aphasia. Clearly enunciated words that lack appropriate syntax and is irregular in speed, along with difficulty following simple verbal or written commands, all suggests aphasia. Delirious/confused patients can usually obey simple verbal or written commands and are more likely to have slurred speech that is grammatically correct.

Question 2 of 6
2. Question
Which of the following defines global aphasia?
Correct
Global aphasia is the most severe form of aphasia and affects all aspects of language (fluency, repetition, comprehension, reading and writing). It is usually associated with a right-sided hemiparesis and is the result of a left MCA or carotid occlusion.

Question 3 of 6
3. Question
Which of the following is true about pediatric blunt chest trauma?
Correct
Kids have bendy ribs/compliant chests and as a result, pulmonary contusions are common and rib fractures not. Rib fractures in kids should be a red flag for significant mechanism of injury.

Question 4 of 6
4. Question
T/F – Liver function tests play an important role in pediatric trauma evaluation
Correct
most kids aren’t alcoholics, so even a small elevation of AST/ALT should raise concern for intra-abdominal injury. Consider CT in these patients.

Question 5 of 6
5. Question
T/F – Significant intra-abdominal injury is very unlikely in an alert, cooperative child who has no pain, a normal abdominal exam and a negative FAST
Correct
FAST does not rule out injury and 20-30% of kids with IAI will have a normal abdominal exam. Algorithms exist to help determine which patients should have a CT, e.g PECARN

Question 6 of 6
6. Question
T/F – the risk of radiation from a CT scan should be the main consideration when deciding whether to scan a child with suspected intra-abdominal injury.
Correct
Use clinical decision tools to support decision to scan. The child will have to survive this injury to have any longterm risk of radiation induced malignancy!
Incorrect
Use clinical decision tools to support decision to scan. The child will have to survive this injury to have any longterm risk of radiation induced malignancy!

The case:
A 16-month old girl with a history of fever of 39 degrees and slightly decreased oral intake for three days. She has no other symptoms of note and is a healthy, fully immunized child. Her vital signs are stable and her temperature is 37.9 after having some Advil at triage. After a careful head-to-toe examination, you note that she looks extremely well and you aren’t able identify a source for the infection.
Question:
Could this be a UTI? What investigations would be appropriate?
The overall prevalence of UTI in febrile infants age 2-24 months who have no apparent source for fever is 5%. There are some groups with higher than average risk of UTI and these groups can be identified. Additionally, the presence of another source of infection (based on clinical history and physical exam) reduces the likelihood of UTI by half.
Individual Risk Factors: Girls
Individual Risk Factors: Boys
Caucasian race
Age < 12 months
Temperature 39 degrees or greater
Fever for 2 or more days
Absence of another source of infection
Nonblack race
Temperature 39 degrees or greater
Fever for 24 hours or more
Absence of another source of infection
In girls age 2-24 months:
1 risk factor: probability of UTI 1% or less
2 risk factors: probability of UTI 2% or less
In boys age 2-24months:
uncircumcised: probability of UTI exceeds 1% even in the absence of other risk factors
circumcised with 2 risk factors: probability of UTI 1% or less
circumcised with 3 risk factors: probability of UTI 2% or less
The probability of UTI increases with the addition of more risk factors, and some of the factors (such as fever duration) may change during the course of the illness, increasing the probability of UTI.
Approximately half of clinicians consider a more than 1% risk of UTI sufficient for further investigation and treatment if UTI is found, to prevent spread of infection and renal scarring.
Recommendations:
If the clinician determines the febrile infant to have a low (<1%) likelihood of UTI, then clinical followup monitoring without testing is sufficient.
If the clinician determines that the febrile infant is not in a low risk group (>1% risk) then there are two options: obtain a urine specimen through catheterization or suprapubic aspirate for urinalysis and culture; or to obtain a urine specimen through the most convenient means and perform a urinalysis. If the urinalysis suggests UTI (positive leukocyte esterase or nitrites, or microscopic bacteria or leukocytes), then a urine specimen should be obtained through catheterization or suprapubic aspirate.
A negative urinalysis does NOT rule out UTI with certainty in children; however it is reasonable to monitor the clinical course without initiating antibiotics.
Urine from a specimen bag CANNOT be used for culture to document UTI due to high risk of contamination.
Case conclusion:
A bag specimen was obtained for urinalysis, which was negative. After discussion with the parents, no antibiotics were prescribed and close followup was available. The child’s fever resolved within 24 hours. The urine culture was also subsequently negative.

Volume Depletion (hypovolemia): refers to any condition in which the effective circulating volume is reduced. It can be produced by salt and water loss (as with vomiting, diarrhea, diuretics, bleeding, or third space sequestration) or by water loss alone (as with insensible water losses or diabetes insipidus).
Dehydration -refers to water loss alone. The clinical manifestation of dehydration is often hypernatremia. The elevation in serum sodium concentration, and therefore serum osmolality, pulls water out of the cells into the extracellular fluid.
Vertebral Artery Dissection – a tricky diagnosis and potentially catastrophic if missed…
Consider dissection in vertigo patients even without history of significant or mild trauma.
Headache and/or neck pain followed by vertigo or unilateral facial paresthesia is an important warning sign that may precede onset of stroke by several days. Dizziness, vertigo, double vision, ataxia, and dysarthria are common clinical features. Lateral medullary (Wallenberg syndrome) and cerebellar infarctions are the most common types of strokes.
Diagnosis – CT Angiography
Treatment – Antiplatelet or Anticoagulation (unless contraindications – see article below)
Cervical Artery Dissection in Stroke Study (CADISS) trial, RCT – antiplatelets versus anticoagulants in the treatment of extracranial carotid and vertebral artery dissections (VADs) = no difference found in outcomes between groups receiving antiplatelets vs anticoagulants. CADISS
Limping Kids – inability to weight bear is always significant…
Need for thorough investigation of non traumatic hip pain in child unable to weight bear. Don’t get biased with previous diagnosis even if by specialists.
Parents often give their children the wrong dose of medications.
Solution:
Provide parents a syringe to draw up medications
Describe the amount of medication in mL, not teaspoons or cc’s
Make sure to give simple instructions
Preamble:
It is well known amongst health practitioners that accurate dosing in pediatrics is extremely important; even a small miscalculation can have catastrophic results, potentially even death. We double check and triple check our calculations to make sure we prescribe the correct weight based dose. This is an excellent practice, and one we should continue to be diligent with, but if we don’t give proper instructions to parents, our calculations will be in vain: in a recent study of parents observed preparing prescriptions for their children, 84% of them made a measurement error!
In this randomized control study, 2110 parents were assigned to 5 different groups in an outpatient office setting. All groups got the same prescription for amoxicillin, and the parents were observed preparing the medication for their children (three times). The groups differed in the tools provided (measuring cup, syringe, or both) and how the units were described (mls, teaspoons or both). (See below).
Results:
Across all groups, 84.4% of parents made at least one measurement error (at least a 20% under/over dose). 21% of parents more than doubled the prescribed dose. The group with the fewest errors was group I: when prescriptions were only written in mLs, and only a syringe was provided. Using the measuring cup, 43% of parents made a dosing error compared to 16% with the syringes (p<0.001).
Parents with lower health literacy and from lower socioeconomic backgrounds were more likely to make mistakes, but like those with better literacy made fewer mistakes in the syringe only group versus the groups that included cups.
Conclusion:
When writing out pediatric liquid prescriptions, describe the medications in terms of mL and specify that the meds should be distributed with a syringe, or provide a syringe from the hospital. This study did not demonstrate whether having practice draw up medications reduced errors, however it seems prudent to have health care workers observe parents give a first dose in the ED if time permits.

It will be created and used by health professionals and the families they care for and its work will drive the highest quality of health care for children and families seeking emergency care in Canada.
Their mission is to deliver the highest standard of care to every child, whether they choose to seek treatment in a pediatric or general emergency department
A big welcome to our nursing / nurse practitioner colleagues at todays rounds. Recent attendance at m&m’s and rounds has been increasing significantly, and a larger venue may soon be required! Just a reminder that ALL (Students, Residents, Physicians, Nurses, NPs, etc) are invited to these CPD (continuous professional development) events.
We were remind that we are frequently faced with patients and their parents requiring advice on the hot topic of food allergies and especially ‘prevention’ of food allergies
Notes from rounds:
If one parent with a food allergy the child has 30% chance of developing Atopy (atopic dermatitis, childhood Asthma, food allergy, allergic rhinitis) in that order – allergic march – developed over childhood in this order
If two parents with food allergy = child risk = 70%
Allergen exposure in early infancy is good if its via the gut, bad if its via the skin (especially if atopic via atopic skin rash)
Due to activation of T-Helper Cells – TH1 vs TH2 = less allergies if TH1 activated via gut than TH2 vis skin
Current Strategies – debunked
Maternal hypoallergenic food eating – false
No cat in house – false – in fact a cat in the house with new infant may be protective
Mechanism
Most kids are getting sensitised via ‘broken skin’ in first year life
Via T-Helper 2 system
Getting exposed via gut stims TH1 system – reduced risk of allergy
Window of opportunity
For kids at risk
4-6 months window for oral sensitisation – may reduce risk of later food allergy
Other Recommendations
No evidence for using soy milk to prevent food allergy
Breast feed until 4-6months then feed them what you want
Wait fro LEAP study – big RCT looking at food allergies and due to present results in next 2 months
Dr Peter Ross presented on Ebola. An extremely stimulating review of the current situation and state of preparedness of own own system. Much discussion was had both during and after the presentation.
It was noted that there is a Provincial plan for managing patient with suspected Ebola. This can be accessed via the Horizon Intranet (Skyline Homepage) This is updated regularly. SJRHEM has printed copies of the plan in accessible areas of the department. These should be accessed and read by all. We have already completed an in-situ simulation for a ‘potential’ ebola case this month. The report for this can be accessed in the Simulation Files – InSitu Sessions – Oct 3rd.
PPE Training is ongoing
Dr Howlett will be posting an update to this website in the next week
