The story of Charlie, like that of the little Alfie, are events on which everything has been said, but without an adequate reflection on some basic principles that concern precisely the respect for life and the quality of care that daily thousands of health workers try to provide terminal patients. We can discuss for a long time what is best for the interest of the individual patient and family, but the value of the scientific method that constitutes the cornerstone of the medical profession can not be ignored.
Likewise it is the duty of the community to uphold the moral integrity of clinical practice by refusing to provide treatments that do not meet a reasonable scientific justification based on evidence of efficacy. Not thinking according to these principles are also betraying the dictates of the heart and not only those of a reasonable science, which should always be at the service of the patient's good, even in the face of death, in a society that should be defined as "civil".
If it is true that the heart has its reasons that reason does not know, it is the heart that, in the case of terminal children, makes the best choices.
He wrote anonymously one of the two hundred health care workers who followed Charlie: "We did not want to lose Charlie, but it was our legal and moral obligation, our job, to become his spokesman when it was time to say enough".
I was interested to read the articles in this month’s journal exploring the difficulties of end of life decisions when parents and their doctors cannot agree.(1–3) These articles reflect the global media attention focused upon several recent tragic cases in the UK, where differences in view between parents and the clinical team led to confrontation and an unfolding tragedy in the public arena. Whilst all these articles describe the complexity they offer little in terms of solutions. Is it possible to prevent future cases from degenerating into public dispute, or is it an inevitable consequence of modern medicine? Have we advanced to a point where children that would have succumbed now live, and so the focus of care has shifted towards how they live rather than if they live or die?
At least part of the solution should be a shift in focus shift toward prevention of conflict in these high stakes clinical areas rather than finding a remedy once conflict has occurred. This is not just about being better at communicating with families. Conflict prevention will require cultural change, the identification of early warning signs and the use of mediation to facilitate communication between parents and doctors at an early stage.
Communication is not just about what we say, but about how we act and the social networks that we live and work in. It was interesting that there was also an article on Family Integrated Care in the same issue of the journal (4). Patel and colle...

At least part of the solution should be a shift in focus shift toward prevention of conflict in these high stakes clinical areas rather than finding a remedy once conflict has occurred. This is not just about being better at communicating with families. Conflict prevention will require cultural change, the identification of early warning signs and the use of mediation to facilitate communication between parents and doctors at an early stage.
Communication is not just about what we say, but about how we act and the social networks that we live and work in. It was interesting that there was also an article on Family Integrated Care in the same issue of the journal (4). Patel and colleagues describe a new way of working in intensive care medicine, where parents are integrated into the clinical team as primary caregivers. They describe how cultural changes to clinical practice enhance the wellbeing of parents and reduce length of stay of their new-borns. Parental integration will surely improve communication between parents and staff. It reduces barriers to effective communication and creates a shared problem rather than adopting sides.
Despite everyone’s best efforts, there will be times when dissatisfaction and conflict arise. To prevent communication breakdown we should identify risk factors within the situation that would lead to early intervention. Forbat et al identified three distinct phases of escalation in paediatric conflicts from mild, through, moderate to severe.(5) The mild stage focussed on conflict triggers, for example, the inappropriate use of language, conflicting messages given to parents by clinical staff, staff making assumptions about parents and a history of previous unresolved conflict. Training clinical staff to recognise conflict early and use mediation skills to de-escalate and resolve it is another intervention. Six month follow up of a cohort of staff trained in one tertiary children’s hospital reported that 57% of respondents had experienced conflict in the six months following the training. Of these, 91% reported that the training had enabled them to de-escalate the conflict.(6) Formal testing of a framework for the early recognition and management of conflicts between families and health professionals is being undertaken by four tertiary hospitals in the UK later this year.
Only after these foundations are in place, where parents are empowered as part of the clinical team, and an open and safe environment for communication already exists, that local hospital review panels and clinical ethics committees and the courts may be able to help when complex clinical decisions need to be considered. These panels should be introduced as part of the wider clinical team. Doctors and parents should approach them together as a united front to listen to their deliberations.
It is vital that we learn how to prevent these high-profile cases from occurring again. There are no winners or losers in these situations, only victims and casualties: parents whose chance of coping with bereavement has been broken, and a career curtailing event for the doctors and nurses who cared for them. When parents and doctors are in conflict, once sides have been drawn the battle is lost. Changing the way that we work with families, mediation as routine practice, and the early identification of the warning signs of conflict is the only way to prevent this from happening again.

The authors have added an interesting opportunity to refine our clinical decision making with the addition of a point of care test (POC) . However I would argue that choice of POC test might be a critical factor here and very much dependent on initial onset of symptoms. Some years ago published data on the then relatively new POC test for Procalcitonin (PCT-Q) indicated that children presenting within 24 h, PCT performed significantly better (AUC 0.96, SE 0.05) than CRP (0.74, 0.12).(1) This could well explain the differences the authors found in the primary care arm of their study. Setting for these tests becomes increasingly important as we see a shift of more children being seen in GP run Urgent Care Centres with a possibly a different spectrum of illness severity.(2) Prospective studies in different settings comparing both of these biomarkers as POCs would be worth further cosideration.

With great interest, I read a recent study by Verakel et al (1). illustrating the utility of a newly developed algorithm for excluding serious infections (SI) in acutely ill children. Their algorithm stratifies patients into three risk groups based on the values of point-of-care C reactive protein (POC CRP) and is meant to assist the decision making of physicians, especially trainees. This method demonstrated excellent diagnostic performance and enabled physicians to rule out 36% of SI in children visiting outpatient clinics and emergency departments. However, their proposed method does raise some concerns about potential negative consequences in the educational context.
The algorithm requires physicians to perform the POC CRP test for all patients regardless of their pre-test probability of SIs. In addition, their model may lead young physicians to draw conclusions about the patients’ clinical features only after estimating the risk of SI based on the POC CRP value and may cause them to neglect the importance of history taking and physical examinations.
As the authors state, the POC CRP is an innovative tool in pediatric acute care; a POC sample can be obtained by a simple finger prick and the test results can be obtained within several minutes. Nevertheless, in pediatric practice sometimes “doing nothing” is better than “doing something”. This may well be one of the most important principles in pediatrics (2-4).

I assume that the authors' algorithm will function as insurance for children with suspected SI; however, debriefing and reflection by trainees and attending physicians alike after each patient encounter is essential even after implementing this technique.

I would like to thank Professor Mitch Blair for his valuable input and bringing up the issue of considering symptoms onset when interpreting point-of-care test results in acute care settings. Recognizing serious infection in children can be challenging, especially at disease onset when the severity of the infection is unclear. Although the choice of biomarker is pivotal in the risk assessment of acutely ill children guided by the point-of-care test result, we had very good rationale to choose C-reactive protein (CRP) as our preferred test.
Previous research:
CRP and procalcitonin were identified as the best inflammatory markers for serious infections in children to date in a systematic review, which only identified studies from hospital settings.[1] A CRP <20mg/L and procalcitonin <0.5ng/mL significantly reduce the risk of missing a serious infection in children. Our recent study on point-of-care (POC) CRP in primary care found an even lower threshold of 5mg/L to rule out serious infection in those children, probably due to the early presentation in primary care, when the inflammatory response is still developing, which indeed confirms the importance of setting.[2]
However, as shown in Figure 6 of the paper by Van den Bruel et al., C-reactive protein and procalcitonin had comparable diagnostic accuracy in the systematic review, as the shape of the curves was roughly similar and the confidence intervals were largely overlapping.[1]

Practical issues:
At the time of study onset, reliable POC tests were available for CRP only, providing test results within 4 minutes.[3, 4] As mentioned by Professor Blair in his e-letter, other tests such as the Brahms PCT-Q, a semi-quantitative point-of-care procalcitonin test, was available at the time, but required additional manipulation of the sample (centrifugation needed to obtain serum or plasma), a sample volume of 200µL (which was 133 times the volume used in the CRP point-of-care test (merely 1.5 µL, roughly a small drop of blood, especially useful in children)) and an incubation period of at least 30 minutes, which would not be manageable within a single acute care consultation. Therefore, it was not deemed suitable for application in our trial.
Study characteristics & findings:
In the present study, we only included children who were not referred by their general practitioner. Taking into account the organization of healthcare services in Belgium, children and parents may present to A&E directly or a consultant paediatrician of their choice, without the need for a letter of referral. This might explain why some children presented at an early stage of their illness to A&E services, potentially reducing the difference in patient spectrum between GP and hospital paediatric settings.
Furthermore, we found that children with a CRP between 20-75mg/L, should be assessed on seven features, including fever duration <1 day, which reflects the effect of disease onset on the CRP level.
In this particular CRP range, children could still have a serious infection if fever was only present for 1 day.
Conclusion:
Procalcitonin has been introduced as an earlier and more accurate diagnostic markers than currently available tests, however evidence of superior clinical accuracy in diagnosing serious infection in children in ambulatory care is still lacking.
I agree with Professor Blair that further prospective studies are needed to compare the clinical effectiveness of using point-of-care CRP and procalcitonin to guide clinical assessment in acute paediatric care.

I read the article with interest and wish to congratulate the authors for their genuine work on a little known subject.
However there are certain points which require elaboration:
(a) It is likely that there are independent genetic factors that are responsible for a baby being born SGA and the same factors may be playing a role in affecting cognitive outcomes.These factors have not been addressed in the study.
(b) Cognitive outcome of a child is the result of certain internal and certain extraneous factors (eg environmental stimulation).The extraneous factors may confound the results of the above study.
(c) Open heart surgery per se may be detrimental to the cognitive development of a child .But there are certain factors such as Bypass time,duration of mechanical ventilation,exposure to hypotensive milieu,etc that need to be explored in order to get an indepth insight into the subject.
To summarize, the article is a praiseworthy effort into a novel field which opens up potentials of further avenues of research.
We appreciated the paper by McCrossan and others but we believe that the diagnosis of pneumonia in children should be made on a clinical ground and that chest X-rays should be considered only in case of a diagnostic doubt or to rule out a complication such as pleural effusion.[1] A X-ray control after a round pneumonia in adults is prescribed with the aim of ruling out an undelying cancer but this is an extremely rare condition in children. Considering this, rather than discussing the opportunity of a radiologic follow up we should consider the opportunity of adapting international guidelines to children.

Sirs,
I read with great interest the article entitled “Treatment and management of children with haemolytic uraemic syndrome” by Walsh and Johnson recently published in Archives of Disease in Childhood (1). In this review, the authors quoted a study performed by our team that investigated the effect of platelet transfusions in children with haemolytic uraemic syndrome (HUS) (2). The main finding of this study is that we did not find statistically significant evidence of worse disease in children who received platelets; however, the authors of the current review outlined that there was a trend towards prolonged need for dialysis among patients who received platelets. A close analysis of this point showed that transfused patients required dialysis for a median of 7 (2-22) days whereas those not transfused for 10 (2-30) days. Therefore, unlike their statement, comparison of these values (p = 0.08) shows a trend towards shorter duration of dialysis in the group receiving platelets. Despite this result, we still suggest that platelet transfusion should be minimized or avoided if possible in patients with HUS.

Response to Dr Eckhard Korsch’s letter: SIDS as the consequence of an immunological burst
I thank Dr Korsch for his supportive and helpful comments with which I fully concur. I remain concerned by the general lack of appreciation by mainstream SIDS researchers of the essential requirement of congruency between risk factors (male gender, prone sleep position, contaminated sleeping surfaces, smoke exposure, lack of breast feeding, high birth order, etc.) and various staining findings of brainstem nuclei or other pathological findings such as intrathoracic petechiae. The silence from the mainstream sector in relation to my ideas is also of concern. Funding of mainstream SIDS research will continue unimpeded as long as facts set out in my papers are not publicised and addressed. Such funding is an unconscionable waste.
In a new paper accepted for publication in Frontiers in Pediatrics1 I have extended the infection paradigm to take into account the as yet unexplained risk factor of prone sleep position. It seems that only in the presence of infection does prone sleep position achieve significance. My thinking suggests a role for the Vagus in unfavourably tipping the homeostatic balance through neuroimmunological pathways.

I thank Mr O’Hagan for his insightful comments. Indeed it is implicit in the ideas put forward in my paper that a specific infection is not the “cause” of SIDS but, rather, it is the immunological response to the infection (bacterial or viral) in the predisposed infant that results in SIDS as proposed by Dr Korsch with his suggested “immunological burst.”
As mentioned in my response to Dr Korsch, I have extended the infection paradigm to take into account the as yet unexplained risk factor of prone sleep position. (See my paper accepted for publication in Frontiers in Pediatrics.1) The presence of infection is a requirement for the effect of prone sleep position to prevail and suggests a role for the Vagus in unfavourably tipping the homeostatic balance through neuroimmunological pathways.

Therefore, unlike their statement, comparison of these values (p = 0.08) shows a trend towards shorter duration of dialysis in the group receiving platelets. Despite this result, we still suggest that platelet transfusion should be minimized or avoided if possible in patients with HUS.

Response to Dr Eckhard Korsch’s letter: SIDS as the consequence of an immunological burst
I thank Dr Korsch for his supportive and helpful comments with which I fully concur. I remain concerned by the general lack of appreciation by mainstream SIDS researchers of the essential requirement of congruency between risk factors (male gender, prone sleep position, contaminated sleeping surfaces, smoke exposure, lack of breast feeding, high birth order, etc.) and various staining findings of brainstem nuclei or other pathological findings such as intrathoracic petechiae. The silence from the mainstream sector in relation to my ideas is also of concern. Funding of mainstream SIDS research will continue unimpeded as long as facts set out in my papers are not publicised and addressed. Such funding is an unconscionable waste.
In a new paper accepted for publication in Frontiers in Pediatrics1 I have extended the infection paradigm to take into account the as yet unexplained risk factor of prone sleep position. It seems that only in the presence of infection does prone sleep position achieve significance. My thinking suggests a role for the Vagus in unfavourably tipping the homeostatic balance through neuroimmunological pathways.

Response to Edward J O’Hagan: Tertium non datur
I thank Mr O’Hagan for his insightful comments. Indeed it is implicit in the ideas put forward in my paper that a specific infection is not the “cause” of SIDS but, rather, it is the immunological response to the infection (bacterial or viral) in the predisposed infant that results in SIDS as proposed by Dr Korsch with his suggested “immunological burst.”
As mentioned in my response to Dr Korsch, I have extended the infection paradigm to take into account the as yet unexplained risk factor of prone sleep position. (See my paper accepted for publication in Frontiers in Pediatrics.1) The presence of infection is a requirement for the effect of prone sleep position to prevail and suggests a role for the Vagus in unfavourably tipping the homeostatic balance through neuroimmunological pathways.
