May 2016 PDF uploaded for the bank holiday

Reintroduction of egg this month with thanks to the BSACI, benign acute childhood myositis, NICE on iv fluids plus a couple of links on when not to use this guidance and a comparison of algorithms for children with a non-blanching rash.  Do leave comments below.

April and May!

I seem to have forgotten to put a blog post up when I published April’s newsletter which contains information on: tonsillectomy for parents, erythema infectiosum (which I think my son had this week), a safety alert about bath seats, tranexamic acid in paediatric trauma and how to make a nasal douche for rhinitis sufferers.

May is now also published and features dangerous dogs, knee pain, dental caries and continuations of both the dermatology and ENT features.  Do leave comments below.

February 2015 (just)

Have just uploaded February 2015 newsletter – with 4.5 hours of February to go….

NICE on gastro-oesophageal reflux disease, how to recognise speech delay, more viral exanthems, resus cards and information on forthcoming allergy courses.  Do leave comments below:

January 2015, late but useful!

January 2015 newsletter is being published late with apologies.  The newsletter is circulated prior to publication to be checked by my 8 paediatric consultant colleagues and any guest authors.  I neglected to attach the newsletter to my initial email, a fact pointed out to me on the 31st January…..  Now checked and ready to go.

Andrew Lock has put together a really helpful guide to viral exanthems with trustworthy links to proper images, Vicky Agunloye is back this month with an invaluable guide to the healthcare professional’s assessment of a crying baby (and his/her mother).  Tom Waterfield has looked at the usefulness of saline nebs in bronchiolitis, there are some more “do not do” recommendations from NICE and a link to Suffolk’s guideline on managing anaphylaxis and its follow up from primary care.  Do leave comments below:

Sick and tired – the truth about infantile reflux

Sick and tired – the truth about infantile reflux

By Dr Tom Waterfield

We have all had that difficult conversation regarding “reflux” when a tired parent has come to us with their “sicky child” and an unshakeable belief that their baby has gastro-oesophageal reflux disease. There is often enormous pressure to provide a solution but how do we decide which children need treatment and what treatments should we use? In view of the recent concerns regarding the use of Domperidone I have chosen to review the current evidence base for the management of this common problem.

 

The North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition(NASPGHAN) and the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) produced a useful guideline document in 20091. This concise 50 page document discusses the evidence base for all aspects of gastro-oesophageal reflux and some of the key points are outlined below.

 

Diagnosis

1)      Physiological Gastro-oesophageal reflux (GER) is common; around 50% of healthy infants will display symptoms of GER. These “happy spitters” will be gaining weight and healthy1.

2)      Faltering growth is unlikely to be due to GERD and alternate diagnosis such as cow’s milk protein allergy should be considered1.

Investigation

1)      The Gold-Standard investigation to make a positive diagnosis of GERD is an impedance study. This has largely replaced the pH study. In this study the changes in the electrical impedance (ie, resistance) between multiple electrodes located along an oesophageal catheter are used to measure reflux. Unlike a pH study the impedance study will also be able to detect non-acidic reflux1.

 

2)      In the majority of cases there will be no role for any other diagnostic test for GERD1

Management

1)      Reassurance

Try to avoid treating simple GER. Reassurance is often all that is required. Before starting any treatment have a frank discussion regarding the risks and benefits1.

 

2)      Positioning “Tummy Time”

There is evidence that lying prone improves GERD when compared with lying supine or semi-erect. It is however, not recommended that children sleep prone due to the associated risk of sudden infantile death (SIDS). A sensible compromise might involve allowing the child to lie prone when awake and supervised by the parent. Semi-supine positions (such as sitting in a car seat) are not recommended and may exacerbate reflux symptoms1.

 

3)      Thickened Feeds

Commercially available thickened feeds (anti-reflux feeds) are safe and relatively effective at reducing visible regurgitation1.

 

4)      Buffering agents and Alginates

There is very little evidence to support the use of alginates (e.g. Gaviscon Infant) in the treatment of GERD although their use is likely to be safe1.

 

5)      H2RAs and PPIs (Unlicensed treatments)

Antacid treatment with Histamine 2 Receptor Antagonsists (HR2As) is effective at healing proven oesophagitis in adults but there is very little data to support their use in infancy. H2RAs such as Ranitidine are relatively safe but their effectiveness is unproven and there are high rates of tachyphylaxis thereby limiting their usefulness in the long term1.

 

Proton Pump Inhibitors (PPIs) such as Lansoprazole and Omeprazole do not demonstrate tachyphylaxis and can be used for longer term acid suppression. Despite this however, randomised placebo controlled studies have failed to demonstrate a benefit of (PPIs) over placebo when treating GERD in infants1.

 

Some studies have suggested that long term acid suppression with PPIs and H2RAs can lead to increased rates of pneumonia and gastroenteritis1.

 

6)      Prokinetics (unlicensed)

ESPGHAN and NASPGHAN advise against the use of all prokinetic agents including Erythromycin and Domperidone. There is no reliable evidence to support their effectiveness at treating GERD in infants and there have been concerns raised over the potentially cardiotoxic effects of Domperidone2.

 

Summary

Reflux is very common with half of infants having some symptoms. In the majority of cases reassurance is all that is required. If symptoms are severe and persistent and an alternate diagnosis is unlikely then consider thickened feeds and “tummy time” as a first line treatment. If this is unsuccessful then consider antacids but be aware that the evidence base for these treatments is limited and they are being used off license. Prokinetics play no part in managing GERD in infants and Domperidone use may be cardiotoxic2.
