re Diagnosing urinary tract infection in children: time to ditch the pad?
Harkensee C, Clennett J, Wilkinson S, et al
Arch Dis Child 2021; 106: 935-936
We read with interest the article by Harkensee et al, (1) suggesting that the urinary collection pad (UCP) no longer had a role in obtaining samples for diagnosis of urinary tract infections (UTI). Whilst it is well established that there is an unacceptably high rate of contamination with UCPs making them unsuitable for microbiological culture, and that the preferred (non-invasive) method for obtaining a sample for culture is by 'clean catch' +/- stimulation or Quick-Wee method, we would suggest that the UCP has a role in screening for UTI, by dipstick analysis of the aspirated pad sample for leucocyte esterase (LE) and nitrites (2). It would be useful, in a paediatric 'acute referral clinic' or Emergency Department, in infants or children, with non-specific abdominal pain, or fever without a focus, where a combination of a negative test for both LE and nitrites can be reasonably used to exclude UTI, and equally a positive LE and nitrite result would indicate a high likelihood of a UTI and the need to obtain a 'clean catch' or catheter specimen for microbiological analysis (3). The advantages of the UCP are that it allows 'point of care' dipstick analysis with inf...

The advantages of the UCP are that it allows 'point of care' dipstick analysis with information to guide clinical decision-making immediately, is passive with minimal parental effort and disruption to the child, there is less likelihood of missing a sample (compared with 'clean catch') and is the preferred collection method of parents.
Perhaps, it's not time to ditch the pad: pads have a place!

The paper by Cappendijk and Hazebroek[1] successfully demonstrates
the problems with diagnosis of appendicitis in the young child.
It makes the important point that diarrhoea may be a feature of
appendicitis and lead to misdiagnosis. In addition, children can have
coexisting pathologies leading to delayed diagnosis. We have seen a cystic
fibrosis child with DIOS (distal intestinal obstruction syndrome) and
appendicitis. Urinary tract infection and appendicitis can also occur
together.
Children with communication problems and learning difficulties are
another high risk group for delay in diagnosis.
The differential diagnosis of appendicitis is large[2] and a child
who presented with abdominal pain and subsequently had appendectomy need
not necessarily have suffered from appendicitis. We would be interested to
know whether the histopathological results were in agreement with clinical
diagnosis.

We read with interest the study and recommendations by Brogan and
colleagues (Arch Dis Child 2000;83:506-507). We agree with them on a
number of issues and wish to draw attention to the following points.
(1) Previous international studies do not support a temperature of
>37.4oC as an inclusion criteria of significant fever for significant bacterial sepsis (SBS).[1][2] A minimum temperature of
38oC for 0 to 2 month old and 39oC for 3-36 month old children is recognised as an indicator of SBS. Hypothermia may also be significant. In children older than 3 years, the highest recorded temperature of 40oC or more in association with other
parameters may be more significant. Interestingly, in their own series, 4/5 with SBS had temperatures of 38.9 to 40.4oC. We propose
that a temperature of at least 38oC should be considered as significant fever.
(2) Lethargy has been mentioned as one of the diagnostic criteria of SBS.
As a diagnostic criterion, it should be defined more objectively rather
than as proposed by the authors. It may be defined as "a
level of consciousness characterised by poor or absent eye contact or as
the failure of a child to recognise parents or caregivers or to interact
with persons or objects in the environment."[3]
(3) Although we fully agree with the cautious interpretation of total WBC
count in relation to serious sepsis, we would like to mention the
importance of absolute neutrophil count (ANC) more than 10000/microlitre, especially in pneumococcal and to some extent in meningococcal sepsis. ANC
of more than 10000 has 76% sensitivity, 78% specificity and 99.2% negative
predictive value in pneumococcal sepsis.[4]
(4) The term toxic needs to be defined as a clinical picture consistent
with a varied constellation of lethargy, poor perfusion or marked
hypo/hyperventilation.[3]
We therefore suggest that the aide-memoir of significant bacterial sepsis
should be modified from ILL to ILLNESS: Irritability, Lethargy, Low capillary refill, Neutrophilia/Neutropenia, Elevated (or low) temperature suggests Significant Sepsis.

The treatment of childhood asthma is controversial: although
oral glucocorticoid treatment in children with asthma was
associated with clinical improvement.[1] There are concerns
about corticosteroids, since stopping drug treatment in
children with asthma results in clinical deterioration,[2]
or in the return of bronchial hyperresponsiveness within two
weeks,[3] with the obvious conclusion that the nature of
drug treatment is suppressive rather than curative. More
importantly, despite prednisolone treatment in acute asthma,
reduction of symptoms and normalisation of pulmonary
function there is evidence of continuing airway inflammation .[1]
However such negative results could be greatly reduced
if more and more pediatricians adopted the practice of
prescribing reduced doses.[4,5] Using the lowest possible
dose and/or alternate-day dosing appears to be safer,[4]
and growth rates[4] and endocrine and lung function return
to normal.[5]
To reduce the risk of systemic effects, it
has been suggested to prefer long acting drugs and start
treatment at 3 PM, since there are no differences compared
to qid dosing, nor influences on 24-h cortisolemia and
cortisoluria.[6]
Completely ignored[1] or disregarded[7] is the issue of
specific immunotherapy (SIT) in children. We have recently
demonstrated that 27/29 (93,1%) controlled studies in 2.042
children and as many controls have shown the effectiveness
of SIT in pediatric age in the treatment of asthma due to
pollens, house dust mites (Der p), epidermal derivatives,
and moulds (p<_0.0001.8 in="in" all="all" studies="studies" the="the" children="children" of="of" control="control" groups="groups" were="were" treated="treated" with="with" available="available" drugs="drugs" and="and" cared="cared" for="for" by="by" their="their" doctors="doctors" as="as" study="study" group.="group." therefore="therefore" _931="_931" have="have" confirmed="confirmed" sit="sit" positive="positive" influence="influence" on="on" natural="natural" history="history" a="a" total="total" remission="remission" asthmatic="asthmatic" symptoms="symptoms" who="who" regularly="regularly" completed="completed" cycle.8="cycle.8" addition="addition" severe="severe" adverse="adverse" reactions="reactions" during="during" are="are" almost="almost" non="non" existent="existent" children.9p="children.9p"/>
From an immunological point of view, oral glucocorticoid
treatment in the children with asthma was associated with
significant reductions in serum concentrations of IL-5,
sCD25, and ECP. However, serum concentrations of IL-5,
sCD25, and ECP remained significantly higher than in
controls, even after treatment with oral glucocorticoids
(p=0.03).[1] Regarding SIT, allergen-induced, in vitro
production of certain cytokines such as IL-4 and IL-10
decreased after SIT; IL-13 (which can induce IgG4 and IgE
antibody production by B cells) increased after SIT.[10]
Therefore IL-13 might play an important role in the
generation of IgG4-blocking antibody during SIT.[10] More
consistent with the reversal of Th2 T cells and associated
cytokines (IL-4 and IL-5) into TH1 T cells and Th1-like
cytokines (IL-2 and IFN-gamma) is the production of IL-12.[11] Thus, the potential ability to shift the Th1/Th2
balance of immune response to allergens creates a favourable
cytokine microenvironment to suppress the allergic reaction
in the asthmatic airway.[12] Accordingly, the production of
IL-5 in asthmatic children treated with corticosteroids[1]
does not appear to be a positive effect.

This article tells us that over the last 30 years the US youth
has shown a decrease in total energy consumed, as well as the percentage
of energy from fat and in particular saturated fats. So what are the
conclusions of the article? That "these trends .... may compromise the
health of future US populations". In the discussion section worries are
expressed about low iron and fibre intakes: despite the fact that both
have risen steadily in the past 30 years. Concern is also expressed about
falling calcium intake, due to a decrease in consumption of dairy
products. US milk intake has always been exceptionally high, and being
rich in saturated fat a reduction was probably desirable. However, the
current lower intake still supplies levels of calcium much higher than
those for children in other developed countries.
There seems little doubt that US children are growing fatter, but I
am at a loss to see in what way their dietary intake explains this.
Presumably the reduction in energy intake is offset by an even greater
reduction in activity, but the effect is that the diet of today's
adolescents, though supplying more energy than required for current levels
of activity, in composition terms appears to be healthier than it has ever
been.
The old fashioned disciplinarian mother used to shout to her children
in the next room "whatever you're doing: stop it!". This appears to
still be our attitude to young people as a group. It is sad to see a
scientific article falling back onto the accepted paradigm that the youth
of today are decadent and unhealthy. Could they not have had the
imagination to actually explore the meaning of these results and even dare to suggest that some things might be improving instead of getting worse?

If sleep studeis are worth doing, they are worth doing well. The study of
sleep disordered breathing is another area of paediatrics that the UK has
stumbled to embrace.[1, 2] Sleep medicine has exponentially increased in
adults in recent years, yet in paediatrics many questions remain
unanswered.
While, van Someren et al made a valiant attempt to answer an
important question,[3] they did so by assessing clinical scores in
relation to a standard which was far from gold, and as such accuracy could
not be determined, only inferred. Clinical scores or simple oximetery are
limited in their ability to identify obstructive sleep apnoea (OSA), being
able to identify significant OSA but not mild/moderate cases.[4, 5] Data
is now accumulating that even mild OSA may be associated with significant
neurocognitive morbidity in children.[6, 7] Full polysomnography is the
current gold standard. The Visilab has not been satisfactorily validated
against full polysomnography, and the results presented in the paper
demonstrated a discrepancy in 2 of 10 simultaneous recordings (a 20% error
rate) with important differences in mean oxygen saturation between the two
systems (93% vs 95%). It is true that full polysomnography may not be
required in all children for the diagnosis of OSA, however this process
should be one of working down from a gold standard rather than edging up
towards it. The arguments used by van Someren against the use of full
polysomnography are weak. Children in dedicated sleep areas tolerate full
polysomnography well: In the 54 full polysomnographic OSA studies
performed in the past 6 months in this unit, sleep efficiency was a mean
of 90% (sd 8%), which includes children with frequent wakening as a result
of their OSA!
Centres in both North America and Australia have dedicated
significant funding in recent years to paediatric sleep laboratories and
the appropriate training of both nursing and medical staff through
specific specialist training criteria; the UK sadly lacks such support.
With the exception of one paediatric unit (concentrating on sleep in rare
disorders) sleep related research in the UK is linked to adults centres.
UK paediatrics needs a sleep medicine wake up call, so that standards can
be set from gold.

paediatrics as presently practised meets the definition of being a process
which enables disabled people and their families to function and
participate fully within their community and support the primacy of the
community in the use of resources is open to question, as Dr. Waterston I
think agrees. This process would require facilitation of a bottom up
approach, ie, giving power and resources from health, education and
social services to the community, and the research testing of such models.
I was proposing a much more confined revolution of tertiary medicine which
let the users and community into the action reorganising the difficulties
and influence that the people in tertiary services face.

The article from the Netherlands by Cappendijk and Hazebroek[1] has again confirmed what is already known in clinical
practice. A recent paper from the Leicester Royal infirmary[2] is almost
identical.
As the authors pointed out, the factors determining the diagnostic
delay are numerous and often cannot be influenced. However, I agree with
their statement that “in a child with abdominal pain which do not settle
quickly, appendicitis should be excluded by early and if necessary
repeated surgical consultations”.[1]
The vermiform appendix varies from 2 cm to 24 cm in length, the
average being about 9 cm. It is longer in the child than in the adult. The
position of the appendix shows a high variation in children. [3, 4] This
variation in the location of the appendix in the abdomen explains the
variation of symptoms seen with acute appendicitis. If the appendix is
retrocaecal or located in the posterior portion of the abdomen,
localisation of the pain and tenderness on examination occur late if at
all. If the appendix is posterior in the pelvis, the pain may localise
only to the lower abdomen. And tenderness to palpation is poorly
localised. The diarrhoea of appendicitis is most common in patients with a
low-lying appendix in proximity to the colon and rectum.[5]
We recently saw a 9-year-old boy presenting with maximum tenderness
in the left iliac fossa. There was a 31-hour history of generalised
abdominal pain followed by vomiting. He was referred to the surgeon with
the diagnosis of generalised peritonitis. Examination under anaesthesia
revealed a mass in the left iliac fossa. Laparotomy confirmed a
generalised peritonitis resulting from a left iliac fossa abscess. This
was from a ruptured appendix, the tip of which was in the left iliac
fossa.

Partsch, Aukamp and Sippell propose that increased testicular
temperature in early childhood might affect later spermatogenesis. They
suggest that 'disposable' nappies could contribute to this and demonstrate
a significant difference between the scrotal skin temperature recorded in
infants using 'disposable' nappies and washable cotton nappies. They
mention in their introductory paragraph that other environmental factors
may be important in the deterioration seen in male reproductive health
over recent years, but do not relate any of these factors to disposable
nappies.[1]
There are many concerns about the use of 'disposable' nappies in
addition to increasing scrotal temperature that may impact on future
fertility and general health. The 'disposable' nappy consists of a plastic
outer layer, a layer of superabsorbant chemicals and inner liner. Nappies
are not subject to government controls or independent testing and
'disposable' nappy manufacturers do not need to disclose the
contents.[2][3]
Recently concern has been raised about the presence of Tributyl Tin (TBT) in 'disposable' nappies. Greenpeace and Women's Environmental
Network have commissioned research which showed that there were
significant levels of TBT in many brands of 'disposable' nappy, including
those on sale in the UK.[4][5] Babies may be in contact with up to 3.6
times the WHOs estimated tolerable daily intake. TBT is an environmental
pollutant which is used in anti-fouling ship paint. It is known to disrupt
the endocrine and immune function of marine shellfish and there are
international plans to phase out its use.
The superabsorbant chemicals used include sodium polyacrylate
crystals which form a gel in contact with urine. This gel can be seen on
the skin in contact with it and there are particular concerns about this
entering the body through broken skin in the nappy area. Sodium
polyacrylate has been removed from tampons as it was associated with the
development of Toxic Shock Syndrome.[6] The inner liner has previously
been shown to contain nonylphenyl ethoxylate, which acts as an oestrogen
mimic, and dioxins.[3]
In addition the use of 'disposable' nappies has important
environmental consequences which may impact on child health. Manufacture
of 'disposable' nappies uses 3.5 times more energy, 8 times as many non-
renewable resources and 90 times as many renewable resources when compared
to washable nappies. The description of nappies as disposable is
misleading. In this country nappies make up approximately 4% of household
waste (800 000 tonnes per year) and every 'disposable' nappy and its
contents ever used is still present in a landfill site.[2]
There are environmentally friendly and safe alternatives to the
'disposable' nappy. Modern washable nappies are very different to the
traditional idea of buckets of terries. There are now shaped cotton
nappies with velcro fastenings, alternatives to nappy pins, breathable
covers and disposable paper inner liners. Concern that the incidence of
nappy rash is higher with washable nappies is unfounded - it has been
shown that it is the length of contact of urine with the skin that is most
important in the development of nappy rash[7] and it may be that an infant
in a 'disposable' has more chance of developing nappy rash as they are
often changed less frequently than an infant in washable nappies. In
addition there are cost savings both to individuals and organisations
using washable nappies and there have been several successful hospital
projects using washable nappies on post natal wards.[2][3]
As paediatricians committed to the health of children we should be
aware of the issues raised by the use of 'disposable' nappies, the
alternatives that exist and sources of information and support for
parents who are concerned about ensuring a safe and sustainable future for
their children.

Harkensee C, Clennett J, Wilkinson S, et al
Arch Dis Child 2021; 106: 935-936
We read with interest the article by Harkensee et al, (1) suggesting that the urinary collection pad (UCP) no longer had a role in obtaining samples for diagnosis of urinary tract infections (UTI). Whilst it is well established that there is an unacceptably high rate of contamination with UCPs making them unsuitable for microbiological culture, and that the preferred (non-invasive) method for obtaining a sample for culture is by 'clean catch' +/- stimulation or Quick-Wee method, we would suggest that the UCP has a role in screening for UTI, by dipstick analysis of the aspirated pad sample for leucocyte esterase (LE) and nitrites (2). It would be useful, in a paediatric 'acute referral clinic' or Emergency Department, in infants or children, with non-specific abdominal pain, or fever without a focus, where a combination of a negative test for both LE and nitrites can be reasonably used to exclude UTI, and equally a positive LE and nitrite result would indicate a high likelihood of a UTI and the need to obtain a 'clean catch' or catheter specimen for microbiological analysis (3). The advantages of the UCP are that it allows 'point of care' dipstick analysis with inf...

The paper by Cappendijk and Hazebroek[1] successfully demonstrates the problems with diagnosis of appendicitis in the young child.
It makes the important point that diarrhoea may be a feature of appendicitis and lead to misdiagnosis. In addition, children can have coexisting pathologies leading to delayed diagnosis. We have seen a cystic fibrosis child with DIOS (distal intestinal obstruction...
We read with interest the study and recommendations by Brogan and colleagues (Arch Dis Child 2000;83:506-507). We agree with them on a number of issues and wish to draw attention to the following points.
(1) Previous international studies do not support a temperature of >37.4oC as an inclusion criteria of significant fever for significant bacterial sepsis (SBS).[1][2] A minimum tempe...
Dear Editor
In reply to the comments by Yim Yee Chan and R Lakshman in which they ask if all patients truely suffered from appendicitis in our study group. The answer is that histopathological investigation confirmed the diagnosis appendicitis in all cases.
Yours sincerely,

The treatment of childhood asthma is controversial: although oral glucocorticoid treatment in children with asthma was associated with clinical improvement.[1] There are concerns about corticosteroids, since stopping drug treatment in children with asthma results in clinical deterioration,[2] or in the return of bronchial hyperresponsiveness within two weeks,[3] with the obvious conclusion that the nat...
This article tells us that over the last 30 years the US youth has shown a decrease in total energy consumed, as well as the percentage of energy from fat and in particular saturated fats. So what are the conclusions of the article? That "these trends .... may compromise the health of future US populations". In the discussion section worries are expressed about low iron and fibre intakes: despite the fact th...
Dear Editor:
If sleep studeis are worth doing, they are worth doing well. The study of sleep disordered breathing is another area of paediatrics that the UK has stumbled to embrace.[1, 2] Sleep medicine has exponentially increased in adults in recent years, yet in paediatrics many questions remain unanswered.
While, van Someren et al made a valiant attempt to answer an important question,[3] they did...
Dear Editor:
I am grateful to Dr Waterston for his commentary. In order to clarify the issues that he raised, I will confirm the following:
(1) I was suggesting that the practice in all branches of tertiary paediatrics should be considered as a disability service from the perspective of the family and child’s predicament. I was not confining the proposal to traditional neurodisability.
(2)...
Dear Editor
The article from the Netherlands by Cappendijk and Hazebroek[1] has again confirmed what is already known in clinical practice. A recent paper from the Leicester Royal infirmary[2] is almost identical.
As the authors pointed out, the factors determining the diagnostic delay are numerous and often cannot be influenced. However, I agree with their statement that “in a child with abdominal pai...
Partsch, Aukamp and Sippell propose that increased testicular temperature in early childhood might affect later spermatogenesis. They suggest that 'disposable' nappies could contribute to this and demonstrate a significant difference between the scrotal skin temperature recorded in infants using 'disposable' nappies and washable cotton nappies. They mention in their introductory paragraph that other environ...
