With millions upon millions of journal articles being published every year it is impossible to keep up.  Every month we ask some of our friends from PERUKI (Paediatric Emergency Research in UK and Ireland) to point out something that has caught their eye.

Article 1: Can we use the NEXUS head CT decision rules in paediatric patients with blunt head injuries?

Gupta M, Mower WR, Rodriguez RM, Hendey GW.Validation of the Pediatric NEXUS II Head CT Decision Instrument for Selective Imaging of Pediatric Patients with Blunt Head Trauma. Acad Emerg Med. 2018 Apr 17. doi: 10.1111/acem.13431.

What’s it about? 

The authors conducted a prospective study over nine years in four emergency departments in the US. Children with a blunt head injury had the NEXUS head CT rules applied prior to having the actual head CT. 1018 patients were included; 27 required neurosurgical intervention and 49 had significant intracranial injuries.

NEXUS correctly identified all 27 patients requiring neurosurgical intervention. It identified 48 out of 49 patients with significant intracranial injuries, but incorrectly classified the 49th patient as low risk (and therefore would not have had a CT with NEXUS – although the patient was observed only).

Why does it matter? 

We have a tendency to over-CT in children with head injury – we worry about the consequences of missing a significant injury. The use of NEXUS in this study incorporates clinician judgement. The patient have already been deemed by a clinician to need a head CT, and then NEXUS is applied. The implication is that it could be used to rule out the need for head CT in this group of patients.

Clinically Relevant Bottom Line:

NEXUS has high sensitivity, meaning that it won’t miss patients who need neurosurgical intervention. But the consequence is that it has low specificity, meaning that there will be many false positives. Consequently we could end up scanning way more patients than we need to. However if we use NEXUS as a rule-out (one way) test, then there may be some potential. If we use clinical judgement to decide whether patients need a CT scan, and then before we scan we apply NEXUS – due to its high sensitivity it could be possible to reduce some unnecessary CTs. However, NEXUS did miss a significant intracranial injury, so maybe it’s not that sensitive after all.

Article 2: How about D-dimers instead of head CT scans?

Langness S, Ward E, Halbach J, Lizardo R, Davenport K, Bickler S, Kling K, Thangarajah H, Grabowski J, Fairbanks T. Plasma D-dimer safely reduces unnecessary CT scans obtained in the evaluation of pediatric head trauma. Journal of pediatric surgery. 2018 Apr 1;53(4):752-7.

What’s it about? 

TBI (Traumatic Brain Injury) related visits to the emergency department have increased substantially over the last decade. Head CT scans are considered the most definitive test in ruling out TBI but expose children to radiation. D-dimer serum analysis has been proposed as a potential biomarker for paediatric traumatic brain injury. This retrospective study aimed to estimate the efficacy of using D-dimer to predict TBI.

The authors analysed 663 patients over a 3 year period who presented head trauma. They included 403 patients with isolated head trauma in the final analysis. Subsequently, they calculated which cut-off value would be most effective in preventing head CT scans without missing significant TBI.

The paper found that using D-dimer with a cut off value <750 pg/µL was effective in preventing 209 CT-scans (39.7%) without missing any significant TBI (isolated skull fractures were considered non-significant, n=2).

Why does it matter? 

Ionizing radiation, rising costs and potential sedation are potential side-effects of CT imaging. Moreover, several screening algorithms have been suggested, but they rely on complete and accurate history taking, subjective to variation. This study suggests that we can safely use D-dimer analysis <750 pg/µL as negative predictive value to rule out significant TBI.

Clinically Relevant Bottom Line:

This early study suggests that D-dimer analysis may become a useful adjunct in ruling out clinically important TBI.  More research is needed in the space and in particular, comparison or combination with existing head injury decision rules.

Article 3: What about an EEG?

Koutroumanidis M., & Smith S. Use and Abuse of EEG in the Diagnosis of Idiopathic Generalized Epilepsies. Epilepsia, 46(Suppl. 9):96–107, 2005 International League Against Epilepsy https://doi.org/10.1111/j.1528-1167.2005.00320.x

What’s it all about?

This elegantly titled article notes in the introduction that “EEG interpretation is still empirical and may be completely meaningless and even misleading without knowledge of the clinical problem”; the crux of this 12 page paper published in Epilepsia in 2005, complete with examples of classical waveforms, and a neat evolution of theories of epilepsy.

Why does it matter?

With the increased availability of EEG in tertiary centres, the need to be thoughtful and rational about the usage of this investigation has evolved commensurate with the ease of access. To further inform and guide your outpatient investigative planning, the authors discuss the usage of EEG in the diagnosis of Idiopathic generalised Epilepsies, and it’s uses for other epilepsy presentations.

Clinically Relevant Bottom Line:

Jump to the bullet points on pages 11 and 12 for the entire list of conclusive for what EEG can and cannot offer your patient. Remember,“ Interictal EEG alone cannot be used for a) Establishing or excluding the diagnosis of epilepsy (including IGEs), b) Providing oversimplified clues for reliable syndromic diagnosis (GSW discharges do not always indicate IGE, and focal changes do not necessarily suggest a symptomatic focus), and c) Prognostication and prediction of possible relapse after the discontinuation of AED treatment.

Article 4: Winter is coming – we’d better vaccinate!

What’s it about?

The Australian National Immunisation Program covers 16 infecious diseases including diphtheria, rotavirus, measles, meningococcal disease and poliomyelitis to name a few. This paper reviewed the NSW Child Death Register and NSW Health notifiable conditions register to identify any child deaths between 2005 to 2014 that may have been prevented by vaccination.

Why does it matter?

Overall fifty-four deaths occurred that were identified as potentially having been preventalble with vaccination. One third of these occurred in children with comorbidities. The most common conditions were influenza (12 deaths) and meningococcal disease (5 deaths). The paper also identified changes in maternal vaccination introduced in 2016 as another avenue to reduce child deaths from influenza.

Aus & UK Free Influenza Vaccines

(Note: In Australia for 2018, all children between 6 months and 5 years are eligible for a free seasonal influenza vaccine in addition to all children over 5 with chronic medical conditions such as cardiac disease,respiratory conditions including severe asthma and other chronic illnesses requiring regular follow up or hospitalisation. Aboriginal and Torres Strait Islander people over 15, pregnant women and those aged 65 years and older are also included in the program. See http://www.health.nsw.gov.au/immunisation/Pages/seasonal_flu_vaccination.aspx for details.

For Autumn/Winter in the UK, the NHS is providing  free nasal spray flu vaccination for children aged 2-3 on August 31st 2017, children in preschool until year 4 and those between 2-17 years of age with long term health conditions. See https://www.nhs.uk/conditions/vaccinations/child-flu-vaccine/ for details.

The bottom line

Vaccines save lives. Winter is coming! Remember to check your patients’ immunisation status. We should support routine vaccinations as well as the influenza vaccine for families with children who would qualify for or benefit from it.

Article 5: Excuse me… Can I ask you a personal question?

What’s it about?

 The NHS winter crisis occurs every year, with news outlets seemingly delighting in showing pictures of patients lining up in corridors waiting to be seen. Our friends in the North have done an amazing job under very trying conditions. Whilst this paper is not strictly about paediatrics it is worth taking a look at its subject matter. Do we take less of a history when we see the patient in the corridor?

To begin to answer this question the authors undertook a survey of 409 emergency physicians at the 2015 ACEP Scientific Assembly. It comprised of three key areas :- demographics, history taking and physical examination. The latter two used Likert scales to report various behaviours. There was a great response rate with 409 of the 568 (72%) physicians approached consenting to take part. 90% reported that they had altered their history taking and 56% their physical exam if other people were present. This lead to delays or failure to diagnose in 35% (of those who altered their usual history taking) and 41% (of those that did not do their usual exam).

Why does it matter?

 Winter is coming for us in the South and an increase in seasonal illnesses. I think it unlikely that we will be subjected to the caseload that the UK has seen but we still have patients show-horned into all corners of the department. We know (intuitively) that clinical care is compromised – delivery of timely antibiotics or pain relief, for example – but this paper makes it apparent that even basic history taking is compromised, increasing the potential for error. I wonder what impact the curtains around our cubicles have?

Clinically Relevant Bottom Line:

 Be mindful that you may (un)consciously alter your history and physical exam technique if you are seeing a patient in the corridor. If you need to ask questions of an intimate nature then do so, in an appropriate environment.

Bubble Wrap Plus

The Bubble Wrap introduced our new Plus segment last month featuring a monthly journal club reading list  from Anke Raaijmakers working with Professor Jaan Toelen & his team of the University Hospitals in Leuven. This comprehensive list of ‘articles to read’ across paediatrics is derived from 34 journals, including  major and subspecialty paediatric journals.

This month’s list features answers to intriguing questions such as: ‘Can a major increase in inhaled corticosteroids prevent asthma exacerbations?’, ‘Can CRP and neutrophil analysis guide us in our decision to perform LP in neonatal sepsis?’ and ‘What is the relation between prolonged breastfeeding and caries?’. They have also included an April’s Fools Day hoax as well, can you spot it?
