Mortality in parents after death of a child in Denmark: a nationwide follow-up study
Discussion
This study of >300,000 parents in Denmark (21,000 of whom had lost a child under 18 years of age, and 290,000 who had not) is a fascinating insight into the long-term effects of a child bereavement.
In the 1st 3 years after the death, the risk of “unnatural” death (suicide, motor accident, other accidents, and inflicted violence) was increased nearly 4 fold in mothers, and by 50% in fathers.
In the period 10 to 18 years after the death, the mothers (not fathers) also had a nearly 50% higher risk of dying from
Unexpected death or death from unnatural causes resulted in higher relative maternal mortality rates than did the expected death of a child. The age of the child at the time of death had no impact on the rates.
This study was only possible because in Denmark every individual has a unique personal ID number for life
Abstract
Background
Little is known about the effect of parental bereavement on physical health. We investigated whether the death of a child increased mortality in parents.
Impact of the pneumococcal conjugate vaccine on otitis media
Discussion
The new(ish) conjugate vaccine is now well demonstrated to protect against invasive pneumococcal disease, but its impact on otitis media had seemed somewhat disappointing - probably because otitis media is often caused by serotypes not in the vaccine (and of course because OM is frequently over-diagnosed anyway and no vaccine can prevent this!).
This large study (37,868 children), now shows a statistically very significant (P < 0.0001) and clinically moderate benefit with a 26% reduction in the risk of 10 doctor visits for OM within a 6-month period, and a 24% reduction in ventilation tube placements.
I think we should all be promoting routine pneumococcal conjugate vaccination for children under 2 anyway, but it now seems reasonable to include less ear infections as a benefit when talking to parents. Although the children in this study were not specifically those exhibiting a tendency to recurrent OM, personally I would suggest it to parents of children in this group.
Abstract
Preventing sleeping problems in infants who are at risk of developing them
Discussion
These investigators found: If around day 7 of age parents keep a diary of feeding for a single 24 hour period, and the baby feeds >11 times in that day, then the baby is nearly 3 times as likely not to be sleeping through the night at 12 weeks of age as a baby who feeds less. They will also take longer to feed, and exhibit more cry/fuss behavior.
In the “feeds >11 times” group, they found a simple intervention (see below) improved sleeping behaviour - 82% vs 61% slept through the night, they also woke less in the day and fed more quickly than those who didn't get the intervention.
It all sounds v simple, and if it works could make a big difference to quality of life for a significant number of parents.
The intervention:
-
First, parents are asked to maximise the difference between day and night time environments, by minimising light and social interaction at night.
-
Second, they are asked to settle a baby judged to be sleepy in a cot or similar place, and to avoid feeding or cuddling to sleep, at night time.
-
Third, once the baby is 3 weeks old, healthy, and putting on weight normally, they can begin to delay feeding when baby wakes at night, in order to dissociate waking from feeding. This is done gradually, using nappy changing or handling to introduce a delay, and does not involve leaving babies to cry.

Sudden infant death syndrome: bed sharing with mothers who smoke
Discussion
Is it safe for babies to sleep in bed with their parents? Quite a bit of evidence on this recently. Many studies (including this one) are limited by their retrospective case series nature (without a true measure of relevant denominators), but this study suggests (v similar to others) that co-sleeping is unsafe if:
-
a co-sleeping parent smokes
-
a co-sleeping parent uses alcohol / drugs that night
-
sleeping on a sofa
Here are the findings of a previous case-control study (Fleming et al BMJ 1999;319:1457-1462 )
Key messsages
-
Cosleeping with an infant on a sofa was associated with a particularly high risk of sudden infant death syndrome
-
Sharing a room with the parents was associated with a lower risk
-
There was no increased risk associated with bed sharing when the infant was placed back in his or her cot
-
Among parents who do not smoke or infants older than 14 weeks there was no association between infants being found in the parental bed and an increased risk of sudden infant death syndrome
-
The risk linked with bed sharing among younger infants seems to be associated with recent parental consumption of alcohol, overcrowded housing conditions, extreme parental tiredness, and the infant being under a duvet

Blood pressure in sleep disordered breathing
Discussion
Sleep disordered breathing (OSA etc) is a known risk factor for hypertension in adults. This small study in children suggests the same occurs in them. This may turn out to be important.
Abstract
Imaging Studies after a First Febrile Urinary Tract Infection in Young Children
Discussion
A recurring theme - what imaging should young children have after their first UTI?
Here is another study supporting the view that extensive imaging investigations are unwarranted.
Here is my v personal interpretation:
-
An acute ultrasound is of limited value, unless the child does not respond to therapy as expected, and maybe in the case of v young boys with possible PU valves (which anyway may be generally excluded on careful history and examination of urine stream).
-
An MCU will demonstrate reflux (and this will be shown about 40% of children with UTI at this age) - this is only of value if you believe intervention (antibiotic prophylaxis) will alter important outcomes (further scarring, hypertension, renal function impairment). Given the lack of evidence that the intervention achieves this it seems generally unwarranted.
-
DMSA scanning can show pathology (pyelonephritis acutely, scarring later) but this rarely changes management.
Given the invasive and unpleasant nature of some of these investigations, and the current lack of evidence for benefit, I believe we generally should not do them in straightforward cases of UTI, and that our efforts and resources would be better directed to early detection by urinalysis and culture during subsequent febrile illnesses in all children with a previous febrile urinary tract infection.

Urethrovaginal Reflux—A Common Cause of Daytime Incontinence in Girls
Discussion
In my experience, this problem is moderately common yet easily overlooked. They girls are often a bit chubby and a careful history usually reveals the problem without the need for any tests. Voiding with the legs widely spread (even sitting on the toilet facing the cistern) will usually fix it and confirm the diagnosis.
Abstract
Systematic Review of Treatments for Recurrent Abdominal Pain
Discussion
Recurrent Abdominal Pain is a common paediatric problem, and the term probably covers a number of different true diagnostic entities. This review article looks at a diverse group of therapies that appear to be effective although success is probably dependant on selecting the right treatment for the specific diagnosis if one can be made.
The full review is worth a read.
(Famotidine is an H-2 blocker (histamine blocker) like ranitidine and Pizotifen is a competitive seratonin antagonist often used to treat migraine. )

The Role of Emergent Neuroimaging in Children With New-Onset Afebrile Seizures
Discussion
Do children with new-onset afebrile seizures need urgent (or “emergent” in US speak) neuroimaging?
This study of 475 cases in Boston suggests that children can be classified into 3 groups: those with a known underlying neurological disorder; those under 3 with a focal seizure; and the rest. for the first 2 groups combined the chance of finding an abnormality was 26% and for the rest (the low risk group) it was 2%.
This supports our current general practice of not performing neuroimaging in previously well children with new-onset afebrile seizures unless they are young and have focal seizure.

Does the Treatment of Attention-Deficit/Hyperactivity Disorder With Stimulants Contribute to Drug Use/Abuse? A 13-Year Prospective Study
Discussion
Does the use of stimulant medication increase the risk of young adulthood drug abuse? This study (and 11 previous studies) suggest that it does not. The subsequent review article says it may even reduce the risk .

Incidence of Cranial Asymmetry in Healthy Newborns
Discussion
In this study of 200 newborns, they found the incidence of neonatal cranial flattening in singletons was 13%, and in twins 56%. The authors state that they have seen a considerable increase in the incidence of posterior plagiocephaly following the changes in recommended sleeping posture for babies (to avoid SIDS) - I'm not sure if this is true, but lots of babies do seem to have flat heads.

Pain Reduction at Venipuncture in Newborns: Oral Glucose Compared With Local Anesthetic Cream
Discussion
Which is better for reducing the pain of neonatal procedures, Glucose or EMLA? The study seems to suggest that Glucose is better (that's lucky because it is less expensive!). I wonder about the potential benefits of using both.
Abstract
Systemic Steroid for Chronic Otitis Media With Effusion in Children
Discussion
This is an old topic, but still relevant. Do Systemic Steroids help to resolve Chronic Otitis Media With Effusion (glue ear) in Children?
This study from one of the key centres of paediatric ENT research, suggests a small but only very short term benefited using steroids. Seems like it can't be recommended as useful therapy.
Here is the Cochrane review conclusion too: “There was no evidence of benefit for steroid treatment for resolution of OME or of resolution of hearing loss associated with OME in the longer term. “
Abstract
Survey of adrenal crisis associated with inhaled corticosteroids in the United Kingdom
Discussion
These authors have published several articles on adrenal suppression with inhaled steroids.
It is a useful reminder that inhaled steroids are safe at normal doses, but we should beware of very high doses, especially of fluticasone.
-
Always try and use the minimal effective dose.
-
Only use doses over 1000mcg if there is a documented benefit (the studies generally don't support higher doses).
-
Consider an ACTH stimulation test for those on doses over 1000mcg they are to continue.
-
Don't stop high doses abruptly.
Abstract
Does breastfeeding reduce allergic disorders?
Discussion
Here are 2 large studies with opposite findings. A NZ study showed no apparent benefit (and possibly some increased risk) but the Swedish study appears to support the view that breastfeeding does reduce allergic disease. I'm sure there will be a lot of debate on this.
The NZ study was longer term (up to age 26years!) but the Swedish study was much larger (but only up to age 2 years). Maybe breastfeeding is protective in the short term but the effect is lost with age (makes some biological sense).

Use of the internet by parents of paediatric outpatients
Discussion
We all know that parents are commonly using the Internet to access information about their children's health problems. Do we always remember to discuss this with them? (they will usually not volunteer this). The information available on the Internet is of very varied quality and parents need guidance in its interpretation.
