I am grateful for the clarification of one specific point made in the original paper published in Archives of Disease in Childhood by Richard Franklin, John Pearn and Amy Peden (Drowning fatalities in childhood: the role of pre-existing medical conditions. Archives of Disease in Childhood 2017; 102:888-93). This relates to their recommendations on swimming safely that reflected both their collective experiential opinion, as well as the recommendations of authorities such as the ‘Royal Life Saving Society – Australia’ and other Australian water safety organisations. Understandably, these authorities will have a significant adult bias and one could – and reasonably should – question some of their criteria, both in terms of ‘seizures’ (i.e. what type of 'seizure') and seizure-frequency. I would challenge the comment made by the International Life Saving Federation in which they state: “Epilepsy submersion and drowning risk is greatest in an identified high-risk group that includes: those with frequent (more than one per year) seizures….”; the majority of paediatricians and paediatric neurologists and probably adult physicians that treat people with epilepsy would not define “frequent” as more than one seizure per year; by definition this would include two seizures per year. My point remains that doctors, and the many different authorities to which they provide expert advice, should no longer consider and cite epilepsy as a single disorder but as a group of disorders...

My point remains that doctors, and the many different authorities to which they provide expert advice, should no longer consider and cite epilepsy as a single disorder but as a group of disorders that affect adults and children, the latter with a markedly heterogeneous range of seizure types, syndromes, causes, treatments and outcomes, all of which can be used to provide an individualised care plan. Failure to do so in certain situations might constitute discrimination against children with an epilepsy.
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.

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.

I thank Mr O’Hagan for his insightful comments.

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.

Confusion may arise in the minds of UK-based readers of this article due to the terminology used in this article, which differs slightly from the notion of “community paediatrics” in the UK.
Whereas in the UK all children receive primary care from a General Practitioner (GP), who then makes referrals to secondary and tertiary level specialists as required, the Israeli “community paediatrician” referred to in this article is actually a primary care paediatrician, who delivers all aspects of medical care to the infant and child, much as the GP in the UK does for both adults and children.
The majority of children and young people in Israel receive primary medical care from a fully qualified paediatrician who has achieved consultant (or specialist) status with a minimum of 4.5-5 years of general paediatric training. Only a minority of children and young people in Israel receive primary medical care from a Family Physician (equivalent to the UK “GP”). Paediatricians in Israel can work either in primary care or as paediatricians with an additional sub-specialty in hospitals, or can work in both settings in parallel (often working part or full time in hospital and moonlighting in primary care).

Paediatricians in Israel can work either in primary care or as paediatricians with an additional sub-specialty in hospitals, or can work in both settings in parallel (often working part or full time in hospital and moonlighting in primary care).
In the UK, the “community paediatrician” is a second tier specialist who deals in specific medical areas , and accepts referrals from the primary medical carer (GP), via a selective referral system. Community paediatricians in the UK usually provide neuro-development and neuro-disability assessments, including autism, but also provide medical services related to child protection and child abuse; children in care of the state (“looked after children”), adoption panels, child death inquiries, statutory advice for children with special educational needs (currently Education and Health Care Plan), special schools and other specialist areas which are developed locally. The UK community paediatrician cannot be accessed on demand and at short notice in the same way as a UK GP or an Israeli primary paediatrician are.
Therefore, the title of the article “Community paediatrics in Israel” actually refers to a system of primary care for children and young people, with on-demand access for parents or children, rather than to a specialist second-tier service. However the changes described in the article refer to expansion of the existing training to incorporate additional expertise in topics such as mental health, behaviour and ADHD, which are increasing in prevalence and demand for service (in Israel as in the UK).
Another term in the article which might cause confusion is “resident” or residency, which in the UK would be equivalent to “registrar”.
The first paragraph in the article ends in a statement that “management of paediatric problems in the community (Israel) is done by paediatricians who had not completed subspecialty training”. This actually means that they are fully trained consultant paediatricians, but are not necessarily certified in a subspecialty, such as paediatric respiratory, neonatology, neurology or haematology, etc.
Whereas in the UK not all paediatricians are at consultant (specialist) grade (i.e. “non career grade paediatricians”), in Israel the only non-consultant grade paediatricians working in hospitals or primary care are those who are in paediatric training (registrars by UK terminology , or “residents” in USA terminology), which culminates in achieving status of specialist /consultant.
Paediatricians in the UK are usually either “community, “acute” (hospital general paediatricians), or specialist in paediatric sub-specialities (mostly based in tertiary level hospital settings).
In Israel many paediatric subspecialties are available both in hospitals and in the community, some of which require a referral from the primary paediatrician, but others can be accessed directly by parent initiative (for example paediatric orthopaedic surgeons or neurologists).
All people permanently residing in Israeli (I have avoided the word “resident” here) are covered by national health insurance, however, as opposed to the single system (NHS) operating in the UK, in Israel four competing public health organisations (Health Funds) operate, delivering a basic universal “basket of services” , and competing with each other by offering increasing levels of excellence or diversity of additional services.
This comment will, I hope, clarify some of the information presented in the article by Porter et al.

Hello,
After reviewing some cases presenting to Bristol with Rhabdomyolysis I wondered if this child had genetics sent for Ryanodine Receptor gene (RYR gene). This can cause malignant hyperthermia and in our case the boy resented with muscle pain on exertion and recurrent rhabdomyolysis. The article below is useful.

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.

These reflect the opinions of the authors, but are generally cognate (albeit more conservative with respect to children) with the recommendations of Royal Life Saving Society – Australia and other Australian water safety organisations (Table 1). We acknowledge that our advice, concerning therapeutic levels of medication and the duration of seizure-free periods, is arbitrary. It reflects our collective experience of seven decades of drowning research, extensive aquatic involvement and participation in national and international formulation of safety doctrines. We also acknowledge that children with persistent febrile convulsions may have lower risks when taken for recreational swimming; but at this stage of knowledge we opine that heightened surveillance is nevertheless required. We agree that there are differential risks associated with different epileptic conditions and pre-existent syndromes. Judgement concerning such risks must reside with a child’s treating physician, as every child is different.
Organisation and Title
Policy reference to epilepsy
Royal Life Saving Society - Australia Epilepsy Medical Policy (2014)
The general rule is that persons suffering from epilepsy are medically eligible for all society awards, patrol duties and aquatic competition provided they have been free of seizures for two years. This is irrespective of whether medications are being taken or not. Where the seizure is the result of any of the following, a further six months must elapse without seizure before water activities can be resumed: a) medication omitted; (b) inadequate sleep; or (c) physical exhaustion. Where a seizure has occurred following withdrawal of medication on medical advice a minimum period of one month must elapse before water activities can be resumed. Where a seizure is the result of; alcohol abuse, head injury or brain surgery water activity may not be resumed for a further two years.
Guidelines (SU6) for Safe Pool Operation, RLSSA (2013)
Qualified lifeguards with a diagnosis of epilepsy are eligible to participate in lifeguard activity provided they have the approval of their medical attendant who is fully aware of the nature and duties of pool lifeguarding. The responsibility for a lifeguard’s management of their epilepsy at all times rests with them and their medical attendant.
Australasian Council for the Teaching of Swimming and Water Safety (AUSTSWIM) Teachers of Aquatics - Access and Inclusion Manual (2013)
A person with epilepsy should be under the care of a doctor and have their condition managed with medication. If this is the case, there is no reason why they should not participate in aquatic activity. Cold water conditions and high-intensity activities should be avoided. Long periods of immersion should also be limited. It is recommended an ‘observer’ be present to watch for signs of a pending episode and assist in the event of an epileptic fit.
Surf Life Saving Australia Seizures and Epilepsy Policy (2012)
Individuals diagnosed with a seizure disorder, child or adult, should not swim, surf, or paddle on craft at a beach; unless they have been free of seizures for at least one year. They should not swim, surf or paddle on craft for at least three months after cessation of medications. Where the seizure is the result of a clear precipitating cause that can be remediated, a further six months must elapse without seizure before swimming, surfing, craft paddling is resumed. Individuals with a seizure disorder should not swim, surf or paddle alone. Companions should be aware of the potential for seizures and the possible need for rescue. They should never hyperventilate for any reason and this is especially important prior to swimming and diving.
International Life Saving Federation MPS 17 – Seizures and Epilepsy Risks for Bathing, Swimming, Lifesaving and Lifeguarding (2016) 4
Bathtub use for children with epilepsy should have direct, close (in the room), and continuous supervision. Older children and adolescents with epilepsy should not bathe or shower with the bathroom door locked.
Epilepsy carries increased relative risk of submersion and drowning. Children and adults should be advised of this increased relative risk. Individuals with unstable, or potentially unstable epilepsy should avoid water activity until stability is re-established.
Epilepsy submersion and drowning risk is greatest in an identified high-risk group that includes: those with frequent (more than one per year) seizures; - those with unpredictable convulsive seizures; and/or those who have other disabilities.
Extra precautions and attention are warranted. This patient group should avoid water activities, or should participate in clear, shallow, still water, with a (securely fastened) personal flotation device that will support an unconscious person, and they should be within arm’s length of a capable support person.
Individuals with stable, controlled epilepsy and no other risk factors, who participate in recreational, instructional, and competitive water activities, should do so in supervised areas and with another capable person. Individuals with chronic disabilities who are intellectually and neurologically able, and medically stable should be encouraged to undertake swimming and lifesaving training.

We read with interest the recent paper by Cook et al(1) reporting their experience with 119 cases of cystic pulmonary airway malformation (CPAM); in which no reported cases showed malignant change. The potential for malignant transformation of CPAM is well-described but extremely rare. Type 1 can predispose to mucinous bronchiolo-alveolar carcinoma in adults, type 2 are associated with pleuropulmonary blastoma (PPB)(2). We describe a case of PPB diagnosed histologically following non-urgent resection of a CPAM.
A 10-month old boy was routinely referred by primary care with episodic wheeze and shortness of breath. He was thriving with no clinical stigmata nor symptoms of malignancy, and no relevant family history.
Examination noted reduced air entry to the left lung; chest x-ray showed extensive left sided hyperlucency with mediastinal shift. Urgent chest CT with contrast demonstrated a very large multi-septated cystic malformation arising in the left lower lobe, with no systemic arterial supply. He was referred to the paediatric thoracic surgeons.
Four months later he had reduced exercise tolerance and one brief admission for pneumonia. Surgical excision took place one year after CT imaging. Resection was uncomplicated and subsequent histological identification of a type 2 CPAM with PPB was unexpected. There were nodules containing malignant spindle epithelioid cells and he has since commenced chemotherapy.

Previous papers have shown that karyotypes from PPB tumours usually contain excessive material from chromosome 8, and an increased incidence of p53 mutations. It has been suggested these mutations differentiate simple CPAM from cases that will later undergo malignant transformation.(3)
We therefore felt it was valuable to report that malignancy does occur in this group of patients unexpectedly, with significant consequences. There may also be a role for testing genetic aspects of CPAMs; some data suggests p53 mutations within CPAMs may be a useful indicator of risk of PPB.

Confusion may arise in the minds of UK-based readers of this article due to the terminology used in this article, which differs slightly from the notion of “community paediatrics” in the UK.
Whereas in the UK all children receive primary care from a General Practitioner (GP), who then makes referrals to secondary and tertiary level specialists as required, the Israeli “community paediatrician” referred to in this article is actually a primary care paediatrician, who delivers all aspects of medical care to the infant and child, much as the GP in the UK does for both adults and children.
The majority of children and young people in Israel receive primary medical care from a fully qualified paediatrician who has achieved consultant (or specialist) status with a minimum of 4.5-5 years of general paediatric training. Only a minority of children and young people in Israel receive primary medical care from a Family Physician (equivalent to the UK “GP”). Paediatricians in Israel can work either in primary care or as paediatricians with an additional sub-specialty in hospitals, or can work in both settings in parallel (often working part or full time in hospital and moonlighting in primary care).
In the UK, the “community paediatrician” is a second tier specialist who deals in specific medical areas , and accepts referrals from the primary medical carer (GP), via a selective referral system. Community paediatricians in the UK usually provide neuro-development...
Show MoreHello,
After reviewing some cases presenting to Bristol with Rhabdomyolysis I wondered if this child had genetics sent for Ryanodine Receptor gene (RYR gene). This can cause malignant hyperthermia and in our case the boy resented with muscle pain on exertion and recurrent rhabdomyolysis. The article below is useful.

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.

The Editorial by Professor Richard Appleton, ‘Seizures, safety and submersion: sense and sensibility’ addresses crucial points relating to children with epilepsy and their optimal, but safe, participation in aquatic activities 1. All agree that the goal is to ensure that children from all backgrounds and with pre-existent medical conditions grow up to have a ‘normal and unrestricted life’ 1. Aquatics are an important activity for all children in both developed and developing nations 2. Our study was undertaken specifically to determine the relative risk of different medical conditions 3. Like the other studies quoted by Professor Appleton, pre-existent epilepsy has been found to pose an increased risk of drowning by a factor of between 2 and 10. The absence of other pre-morbid diagnoses may either reflect a selection bias in that parents are not allowing those children to participate in aquatics or that parents recognise the hazards and put in place appropriate safety strategies. Differential aquatic exposure rates, specific for different pre-existent medical conditions, are unknown; and therefore denominators which define specific risks remain unknown. In our paper we recommend that ‘Children with epilepsy may swim with safety if drug levels are in the therapeutic range, the child has been seizure-free for 6-12 months and compensatory extra supervision is in place’ (3). These reflect the opinions of the authors, but are generally cognat...
Show MoreWe read with interest the recent paper by Cook et al(1) reporting their experience with 119 cases of cystic pulmonary airway malformation (CPAM); in which no reported cases showed malignant change. The potential for malignant transformation of CPAM is well-described but extremely rare. Type 1 can predispose to mucinous bronchiolo-alveolar carcinoma in adults, type 2 are associated with pleuropulmonary blastoma (PPB)(2). We describe a case of PPB diagnosed histologically following non-urgent resection of a CPAM.
Show MoreA 10-month old boy was routinely referred by primary care with episodic wheeze and shortness of breath. He was thriving with no clinical stigmata nor symptoms of malignancy, and no relevant family history.
Examination noted reduced air entry to the left lung; chest x-ray showed extensive left sided hyperlucency with mediastinal shift. Urgent chest CT with contrast demonstrated a very large multi-septated cystic malformation arising in the left lower lobe, with no systemic arterial supply. He was referred to the paediatric thoracic surgeons.
Four months later he had reduced exercise tolerance and one brief admission for pneumonia. Surgical excision took place one year after CT imaging. Resection was uncomplicated and subsequent histological identification of a type 2 CPAM with PPB was unexpected. There were nodules containing malignant spindle epithelioid cells and he has since commenced chemotherapy.
