The St.Emlyn’s Podcast

This episode of the podcast is a live recording from the PREMIER Conference of John O Neil discussing penetrating injuries with learning points that are useful for clinicians who look after both adult and paediatric patients. 

There are three main mechanisms – violence, impalement and self harm, although the first is by far the most common. 

Penetrating injuries are rare but have significant morbidity and mortality. The key is early and accurate diagnosis, and many can be managed conservatively. The distribution of penetrating injuries across the UK differs widely, with most in the London area, although as seen in the news recently can happen anywhere.

Remember how traumatic it is to be a trauma patient. We put you on a bed, cut off your clothes, stick needles in you and take your family away. Some will also just not engage with you (teenage boys particularly) making assessment difficult. Be kind. Don’t get frustrated.

Physiologically there may be a strong vagal response that can hide some of the signs we’d expect. Also, bear in mind the events prior to the injury – the child may have been running a considerable distance (before and after the incident) raising their lactate (but don’t assume this is the cause). Children tend to ‘fall off a cliff’ – they appear well, but can suddenly decompensate – keep the momentum to definitive management going and do not be falsely reassured.

John mentioned a great friend of St Emlyn’s Vic Brazil and we would heartily endorse you have a look at her work.

Chris brought us his reflections amnd knowledge from some of his extensive experience as a military EM consultant in two wars. Blast injury could be blunt, penetrating, may involve major haemorrhage: you have to expect any injury possible. It’s worldwide and it’s getting more common. 

Blast injury affects every body cavity, but it is the CABC approach that matters, Doing the basics well is still the key. Bleeding points may not be obvious so apply tourniquets wherever stops the bleeding.

Often patients will not arrive in ones or twos but as a whole group affected by an incident, so it is vital we are prepared. The Paediatric Blast Injury Field Manual is a free resource available to download here and is highly recommended.

Chris Hillman is a Consultant in Emergency Medicine and Paediatric Emergency Medicine, working in Southampton. Serving in the Royal Navy since university, he has deployed on Ships, Submarines and with Commando units globally, and with the Army to Afghanistan and Iraq. He is the outgoing Consultant Advisor in Emergency Medicine and Clinical Director Commando Forward Surgical Group. 

This is the second in our series of talks recorded live in June 2023 at the PREMIER conference.

Looking after patients with non-epileptiform seizures are a challenging, and common, event in the Emergency Department. 10% of attendances at paediatric neurology clinics are thought to be 'functional' and a lot of these will also present to the ED. These problems can involve a wide range of physical or sensory manifestations, almost all of wide have significant differentials which we cannot miss.

A large number of these patients can end up with an incorrect diagnosis, some of this due to confirmation bias by clinicians, but also some with psychogenic non-epileptiform seizures may coexist with organic problems.

The history is key and can be helped significantly by watching videos of events. There may be other factors giving a clue to a non-epileptic cause. Sometimes this will only happen in one place, like school, and the history may be inconsistent. Awareness and generalised bilateral movements, with episodes that are different each time all point to a non epileptiform origin. And then there are symptoms just 'not fitting' with our knowledge of dermatomal distribution.

There are Red Flags - Events happening during exercise, neurological signs, unpredictability and patterns to the events all point to a more sinister diagnosis

Management is incredibly difficult, particularly in trhe ED. Don't suggest an organic diagnosis and leave some ambiguity. There is time to get more information and there are few definitive diagnostic tests. EEGs are notoriously unreliable. Self help groups can help.

Steve Warriner has worked as a paediatrician at the QA in Portsmouth for the last 16 years. He trained in various regions in the UK including the Midlands, Yorkshire and the North East of England before working in Somerset for a brief period. He has a particular interest in epilepsy and neurological conditions in children and lead the district epilepsy service in Portsmouth. He teaches on the British Paediatric Neurology Association epilepsy training courses both in the UK and across the world. He was part of the team who designed and implemented the training course (initially in Myanmar) and the method of cascade training has recently been recognised by the World Health Organisation and the course now runs in nearly 30 counties in 3 languages. Steve recently chaired a multidisciplinary working group to update the Advanced Life Support Group guideline for management of prolonged seizures. In his spare time, Steve is a triathlete who qualified for and competed in the World Ironman Championship race in Hawaii in 2022.

This is the first in a series of podcasts, recorded live at the Premier Conference in Winchester.

In this episode, David James challenges our current practice when we give a 'weaning plan' for children discharged with wheeze. 

There is a plan here that you can review and give to patients and their carers.

This is the first podcast in our new series from St Emlyn's Medical School. They are specifically aimed at healthcare students and focus on the Medical Licensing Assessment (UK) presentations in particular but will be useful wherever you listen in the world. 

Each episode has a standard format with a case to set the scene, a set of learning objectives, a discussion, a summary and a case resolution. 

There are comprehensive listening notes on the dedicated website, as well as a growing set of other resources. 

We hope you enjoy listening. The rest of the podcasts can be found on Spotify, or wherever you get your podcasts. 

The music for this series (just as it is for the St Emlyn's Podcast) is composed by Greg Beardsell

The latest CAN is one of our brand-new 'revision editions' -- brief podcasts aimed at covering the essentials of critical appraisal for medical students and junior doctors preparing for exams.

With the help of Gregory Yates, an academic doctor based in Manchester, this episode introduces two core concepts: sensitivity and specificity. These are two ways of thinking about the accuracy of a diagnostic test. Knowing the sensitivity and specificity of an investigation will give you a decent idea of how it should be used in the emergency department.

Sensitivity (Sn) describes the chance that a test will be positive if your patient has the condition you're testing for. Some people call it the 'true positive rate' or alternatively the positivity in disease (PID) rate. If you need a hand remembering it, you can always remember that PID is a sensitive issue.

Meanwhile, specificity (Sp) considers the chance of a test being negative if the patient doesn't have the condition you're testing for. It's the 'true negative rate' or alternatively the negativity in health (NIH) rate. There are times when we particularly need a test to have a high sensitivity. This is generally when we want to be particularly confident that a test accurately identifies everyone with the relevant condition because we really don't want to miss it. We need a high sensitivity to rule out disease. (Sn-uff it out). At other times, we need to be confident that a patient with a positive test actually has the disease - for example, if the treatment is unpleasant or involves exposing patients to risk. In that case, we want a high specificity to rule in disease. (Sp-in it in).

In this CAN, we use D-Dimer as an example of a very sensitive investigation: it’s positive in nearly 100% of cases of venous thromboembolism. Specificity describes the likelihood that the test will be negative if your patient does not have the disease. We use HbA1c as an example of a highly specific investigation: it’s rarely used in the emergency department, but if it’s elevated, we can be almost certain that the patient is diabetic. HbA1c is almost never (

Our regular monthly round up and chat from the St Emlyn's blog. We talk about the use of artificial intelligence in research and the use of remifentanil instead of neuromuscular blockade in rapid sequence intubation. Plus more about the StEmlynsWILD conference and Simon's new role as Dean of RCEM and how you can get involved. 

Long term listeners to the St Emlyn’s podcast may remember our series entitled ‘Critical Appraisal Nuggets’ (CANs). We are absolutely delighted to reinvigorate this project under the leadership of Professor Rick Body, with the episode on semi structured interviews.

In this easily digestible and succinct podcast Rick and Laura Howard go through the pros and cons of setting up semi structured interviews and how these can be used effectively in qualitative research.

In the latest episode, we cover a qualitative research technique: semi-structured interviews. Qualitative research might be out of your comfort zone: we’re generally more comfortable with quantitative measures – numbers and statistics. It’s something they have experience with, having previously published a paper exploring the impact of events that happen at work on the wellbeing of emergency physicians. This was a labour of love for Laura. Laura wrote a powerful blog about it here.

Semi-structured interviews are a great way to get the really rich data we need to understand something in greater depth. They allow us to ask ‘why?’ as well as just ‘what?’, ‘who?’ and ‘when?’. But reading qualitative research papers can be difficult when it takes us out of our comfort zone. In this CAN podcast, Laura and Rick take us through what semi-structured interviews are, why we might use them, how you design and conduct them, and they also have some pearls of wisdom about how to make transcribing them a lot less painful. By the end, we hope that you’ll feel confident with the basics of the technique. And if you want to practice your critical appraisal, why not put their study under the microscope?
