StatsMiniBlog: Choosing a test

30 Jun, 15 | by Bob Phillips

StatsMiniBlogThis is a very, very simple approach to picking a method of analysis for a research study (that’s looking at one comparison, and with lots of caveats – this is VERY simple) … but as a start, you may as well go with this picture.

Is breathlessness worth reporting at all?

26 Jun, 15 | by Bob Phillips

6za74k736pc03j9fp8h5gialh.500x223x11Again, deliberate bait in the title which I do hope you’re all used to by now …

But the question arose when I started to look at this paper published in the Archives, addressing the question of observer variation in clinical assessment of wheezy kids. Mostly, I think wheeze = mediastinal mass (fast onset -> T-cell lymphoma, slow onset -> Hodgkin’s lymphoma) or wheeze = aspergillus infection, if hot & leukaemic,  but I do recognise that asthma is, occasionally, the correct answer.

But how breathless are wheezers and do different clinicians agree?

Guest Blog: The trials and tribulations of answering clinical questions

23 Jun, 15 | by Bob Phillips

 For a recent evidence based paediatrics assignment we had to answer and present a clinical question. I’m sure you are well acquainted with the process; construct your question in standard PICO format, search your secondary and primary sources, critically appraise the evidence and draw your conclusions.

Having noted a trend towards starting lamotrigine rather than valproate in adolescent girls, because of the concerns of teratogenicity, and wondering if this is at the expense of good seizure control, my question was:“In adolescent girls with newly diagnosed generalised epilepsy (population) is lamotrigine (intervention) as effective as sodium valproate (comparison) at achieving seizure control (outcome)?”

Basics: Another way to look at it all

19 Jun, 15 | by Bob Phillips

While the theory of different styles of learning (kinetic, verbal, visual etc etc ) may be thoroughly garbage it’s pretty much true that folk often prefer one way of getting their learning. Some like listening – catch our podcasts for that – others doing – so we have #ADC_JC – and many readers of this blog will like, well, reading.

Anyone particularly value pictures?

Practical Authorship: Should I write a Case Report?

Quill_penShould you write a case report?

There is a short answer here, and there is a long answer.  I will give you the short answer, but only if you promise to read the rest.  The short answer is “no”*.  The longer answer is…

Guest blog: “To Play or not to Play”?

12 Jun, 15 | by Bob Phillips

IMG_0196Play in its most intimate of forms allows for free expression, exploration, joy, and excitement . For others it’s a welcome distraction. What makes play become a tool, a balance barometer, a universal subject, is when it is introduced or offered to a child/young person (CYP) who requires an intervention, treatment or one who is in the midst of trauma or a long term diagnosis.

Clinical settings are strange, sterile environments, where your senses are overloaded, where you become overwhelmed by people, sounds, smells and sights – it’s a wonder that play has a place in such a frantic space or moment in time, but it does. For the hospitalised child enhanced information of their condition can lower a child’s fear and the pain they experience. more…

Practical Authorship: Who is Reading?

9 Jun, 15 | by Ian Wacogne

Quill_penIf you write, who is reading?

 

Something I find strange is that people don’t draw on their own experience of reading when they begin to write.  As such, they often don’t write in a way that they themselves would be drawn to.

 

Let me start here with a couple of questions. Please answer honestly.

StatsMiniBlog: Cluster analysis

5 Jun, 15 | by Bob Phillips

20140204-233354.jpgLumps and groups and clumps and factors … all sorts of ways of describing how Things Can Be Similar.

Cluster analysis is a statistical term that refers to an approach – not a particular method – that seeks to work out how to group items together so those in the same group are maximally similar to each other, and maximally different to things in other groups. Like cats and dogs.  more…

I ended the last blog post with the thought that you might write about things that irritate you, or that interest you.

#ADC_JC: We’re Top 5 Material

26 May, 15 | by Bob Phillips

Shameless, we are. The now world-famous #ADC_JC – an online, Twitter-based, synchronous journal club addressing top articles of relevance to paediatrics & child health, has been Officially Recognised as in the Top 5 of such journal clubs. (Thanks @DrHillyHazel for pointing us to this.)

In this article, a systematic approach to the Twitter stats of such interactive journal clubs was undertaken, and showed that the gang that join in with ADC_JC are the most engaged and interactive of the lot.

 

Now that makes me pretty sure you’ll want to join in too … so please feel free to drag up a Twitter account, and set yourself, a glass of wine/beer/milk and a copy of the paper under discussion up on a comfortable surface and take part. For those who are unfamiliar with it, have a look at some of the storify links from the ADC_JC main page and maybe step through this tutorial.

See your tweets too, next time on @ADC_JC?
