Although the paper of El-Radhi et al[1] presents
interesting data about decreases in inflammatory markers during the
resolution of acute asthma, some of their conclusions are not valid.
First, acute asthma has a tendency to resolve without corticosteroid
therapy.[2] Since all of the children with acute asthma (quite rightly)
received steroids, the observed effect may equally reflect processes
associated with spontaneous resolution. Indeed, corticosteroids do not
inhibit the release of eosinophil cationic protein (ECP) from eosinophils.[3] Second, the normal controls are inadequate. Atopy per se is
associated with increased serum levels of ECP,[4] and it is therefore to
be expected that the asymptomatic atopic asthmatics will have higher ECP
levels than the mostly non-atopic controls.

In response to the short report of Brogan and Raffles.[1]
Although studies on children with petechiae who appear clinically unwell are important, the management of such children should pose few dilemmas in deciding to treat for presumed sepsis. A more challenging group is those with petechiae who appear to be well. We feel this group generates anxiety for clinicians who worry about missing occult or early sepsis.
To address this question, we retrospectively identified from a 1 year period, all children who presented with petechiae to our emergency department.
We wanted to focus in particular on well, afebrile children with petechiae of unknown cause. Therefore, unlike Brogan and
Raffles, we excluded those at the time of presentation thought to have clinical sepsis, those with idiopathic thrombocytopaenic
purpura or Henoch- Schonlein purpura and those with suspected non-accidental injury. We also excluded febrile children,
but unlike Brogan and Raffles, we defined fever as a temperature of 38C or more (in accordance with the study of Mandl et
al [2], the largest prospective study to-date on the incidence of sepsis associated with petechiae).
31 well, afebrile children with petechiae were identified. Each had comments in their notes like 'appears well' and the
diagnosis for each was 'viral illness', plus or minus mechanical causes for petechiae. In addition, objective criteria such as
pulse oximetry, capillary refill time and blood pressure were all normal. Having identified this cohort, we reviewed laboratory
data and outcome for each child.
10 children were less than one year, 10 between one and five years and 11 over five years. 19 had blood cultures done - all
negative. 9 of these also had meningococcal PCR done - all negative. Of the 12 without blood cultures, 1 had meningococcal
PCR done, which was negative. 27 had full blood counts - 3 showed an elevated white cell count and none had low white
cell counts. 19 had C-reactive protein measured, 9 of which were elevated.
12 children were admitted - all remained well (despite this 9 were given antibiotics, which were discontinued after 48 hours).
19 were discharged, having received no antibiotics. As far as we are aware, no children subsequently developed clinical
sepsis.
The results of our study are in keeping with those of Mandl et al [2], who found the incidence of clinical sepsis amongst
(febrile) children with petechiae, who appeared well at the time of presentation, to be nil.
Furthermore, our study shows that management of well children with petechiae is highly variable. Lack of consensus among
paediatricians on the management of petechial rashes has been well documented [3]. In our own department, we are
considering implementation of the following guidelines for the management of well, afebrile children with petechiae, although
we acknowledge that larger prospective studies are required.
1. That such children be observed in the emergency department for 4 to 6 hours and if they remain clinically well and
afebrile, discharge without antibiotics would be safe.
2. Laboratory investigation is probably unnecessary, unless indicated to exclude ITP.

The recent article by Eiser and Morse was an excellent
review of studies in this area.[1] We agree that emphasising the outcome
of the child as a whole, rather than using raw clinical indicators is
important, and that measuring Quality of Life (QoL) should help with this.
The article refers to an instrument which we developed to measure QoL in
children with Crohn’s disease.[2] The initial development actually took
place in the United Kingdom not the USA, further extensive development has
subsequently been done in Canada and the Netherlands, as well as the UK.
Specific concerns were determined from interviews with 82 Canadian
children with Inflammatory Bowel Disease (IBD) aged between 8 and 16
years. These issues were incorporated into an “item reduction list” which
was administered to a further 117 Canadian children with IBD, who ranked
the issues in terms of importance and frequency. From the 50 highest
ranking concerns a 32-item paediatric IBD QoL instrument (IMPACT) has been
developed. The instrument has shown strong correlation with patient global
assessment of QoL and contains questions encompassing 6 domains: bowel
symptoms; systemic symptoms; social/functional concerns; body image; test/treatment concerns; emotional concerns.[3]
We agree with the authors concerns about cross-cultural adaptation of
QoL instruments. We sent the Canadian “item reduction list” to 53 British
children with IBD and asked them to rank the issues in the same way as the
Canadian children did. In addition they were asked if they had any other
concerns and we also conducted focus groups to identify any additional
concerns. The British children with IBD generally had the same concerns as
their Canadian counterparts but the QoL appeared to be worse in British
children.[4] This encouraged us to believe that IMPACT would also be
valid in the UK, but pilot studies have shown that many UK children, their
parents and health professionals found the questions to be too complicated
and/or upsetting. Similar problems have also been experienced by our Dutch
colleagues who have developed a simplified, child-friendly version of the
questionnaire (called IMPACT-II) incorporating the same concerns.[5] In a
pilot study of 21 UK children with IBD who completed both versions of the
questionnaire 16 preferred IMPACT-II as they felt it was easier to
understand and quicker to complete.[6]
We also share the authors concerns that questionnaires can be time
consuming and difficult to complete. We have therefore developed a
portable, touch-screen computer version of IMPACT-II which can be used in
the outpatient clinic. In a further pilot study of 19 UK children with
IBD who completed the paper and computer versions, 17 preferred the
computer version.[7] This is currently undergoing further validation and
we hope that it will be a major step towards providing information about
QoL in children with IBD in the clinical setting.

Partsch and colleagues speculate that a rise in
testicular temperature in infants and young children
consequent to the wearing of modern plastic lined disposable
nappies [diapers] may have contributed to both the fall in sperm
counts and the increase in testicular cancer which have been
reported in some countries.[1] In support of this hypothesis
Partsche et al refer to reports of rising incidence rates in
testicular cancer.[2-6] These studies report increased
cancer risk in men born from before 1900 to 1988 diagnosed
up to 1988, from 1916 to 1978, before 1970, from 1907 to 1981,
and from 1865 to 1975, respectively. None reports incidence
of testicular cancer in men who have had the opportunity to
wear modern disposable nappies which have only been widely
available since the late 1970s. There is some suggestion
that the rise in testicular cancer may not be continuing.[7]
There are no data on testicular cancer incidence in men who
are likely to have worn modern disposable nappies as the
peak age for this disease is the late 20s and the men are
simply too young. Similarly, the reports of a declining
sperm count do not include any men born after 1975,[8-11] and even the most recent study from Denmark
includes men born only before 1978.[12]
There is no way that
modern disposable nappies could have contributed to the
changes in male gonadal health reported in men observed to
date since all studies are of men who were born before they
were available.
Partsch et al[1] claim that the scrotal cooling mechanism
was often completely abolished in boys wearing modern
disposable nappies. This would appear to be
over-interpretation of the data they had available, for two
reasons. Firstly, they compared 24-hour mean scrotal
temperature with spot rectal temperature and were unable to
take into account the considerable circadian variation in
core temperature in infants.[13] Secondly, they used
measurement techniques validated in adults but not in
nappy-wearing infants. They have not demonstrated that their
methods, which included covering a considerable portion of
the scrotal surface with adhesive tape, did not interfere
with two aspects of scrotal cooling, ie, evaporation from the
skin surface and contraction and relaxation of the scrotal
sac. There is the very real possibility that the measurement
process itself increased scrotal temperatures in all
children.
There are several inconsistencies in the results table (table 1 in the paper by Partsch et al)[1]; for example, the
mean temperatures and the calculated difference between
temperatures measured with modern plastic lined disposable
nappies and cotton nappies can not be reconciled, which the
authors may wish to clarify.[1]
Further scientific research is clearly needed to establish
the normal range of temperatures in infant testes and
the extent to which they may be affected by different types
of nappies and also the extent to which any changes may
affect testicular health. However, it is clear that modern
plastic lined disposable nappies can have played no role in
the changes in male gonadal health reported worldwide to
date.

Conflict of Interest
I have provided advice on scientific and epidemiological aspects of this
study to 2 trade associations which act on behalf of modern plastic lined
disposable nappy manufacturers EDANA and AHPMA.
We thank David Strauss for his interest in our work but he fails to
substantiate
his claims that there are 'substantial problems' with it.
First, we wish to correct an error on page 470 (Arch. Dis. Child. 2000; 83: 470), column 2, line 11,
`dying
before' should read 'surviving until'.
With regard to Strauss's remarks on LAS, both the abstract and the
results
section include the phrase 'survived to age 5', so Strauss has not
explained our
result, but
merely repeated this information. Even the brief precis of the
LAS in the paper makes it clear that it would be difficult, if not
impossible,
as well as unwise, to attempt to complete it for a 2 year old.
That some-one might misquote our work is true, but not our responsibility.
With regard to mobility and mental ability, we have reported exactly
what is
measured, and have referenced other work which includes measures different
from
ours. It appears that Strauss wishes we had speculated about information
we do
not have. Note that IQ was constructed to have a mean of 100, and
standard
deviation of 15. On this scale, fewer than 4 in 10,000 people would have
an IQ
less than 50, our definition of severe cognitive disability.
Fewer than 5 in 10 million people would have an IQ of less than 20, the
number
mentioned by Dr Rosenbloom.
It seems obvious that persistent vegetative state or indeed leukaemia
or need
for ventilation twice a year are clearly additional and largely
independent risk factors for death which any court would take in to
account.
With regard to hazard or odds ratios, our discussion does comment on
multivariate versus univariate models (Arch. Dis. Child. 2000; 83: 472).
Whether univariate or multivariate, one still has a relative statistic, so
that any lack of similarity in the baseline categories will be relevant.
Strauss claims that `The real reason is simpl(y)' the difference between
multivariate and univariate analyses: he gives hazard ratios for tube
feeding,
and states that the univariate ratio of 23.6 is 'about as large as any in
Hutton
et al's Table 5'. However, Strauss fails to quote a factor - hand use -
which,
unlike tube feeding, can be
easily compared with our work, and that of South East Thames. In
correspondence
with
Hutton, Strauss stated "Re. hand use: our multivariate OR was 1.52 and
our
univariate OR was 5.69": a value which is substantially less than 23.6,
and than
our results.
Further, Strauss states that this lower ratio is for a more disabled
group: "But
our
definitions are very different from yours. Our 'bad' group is 'no
functional use
of hand' ... while your 'severe manual disability' group is much more
inclusive'
...". Thus the `reason' Strauss gives fails to explain the difference in
results
for manual disability.
We thank Dr Grigg for his interest in our work.[1] We agree that the asthma attacks may have resolved spontaneously in some cases, which was
precisely why we stated that the markers fell in association with steroid
therapy, and nowhere implied causality. Nevertheless, the statistical
analysis suggests that the chances this occurred at random are extremely
low.

precisely why we stated that the markers fell in association with steroid
therapy, and nowhere implied causality. Nevertheless, the statistical
analysis suggests that the chances this occurred at random are extremely
low.
We agree that corticosteroids do not inhibit, except at very high
concentrations, degranulation of the eosinophils induced by incubation
with opsonised particles, such as Sepharose beads in vitro.[2] However,
there is overwhelming evidence that cytokines such as IL-5 prime
eosinophils for increased release of granule proteins in this situation,[3,4] and that they inhibit cytokine-mediated prolongation of eosinophil
survival.[5] These observations, coupled with the abundant evidence that
corticosteroids reduce the expression of eosinophil-active cytokines, such
as IL-5, provide a convincing chain of evidence linking the clinical use
of corticosteroids with reduced release of eosinophil granule proteins in
vivo.
With regard to the controls in this study the ratio of atopic to non-
atopic asthmatics was 4:1 and of atopic to non-atopic controls was 3:1.
These differences are not significant by chi-squared testing. Whilst we
agree that more controls might have strengthened our conclusions,
nonetheless the evidence of unresolved inflammation after an apparently
clinically adequate course of prednisolone, as shown by the elevated
levels of IL-5 and sCD25, remains strong.

Professor Salazar-De-Sousa,[1] commenting on the recent paper by Høst et al,[2] maintains that recent prospective and randomised clinical studies have shown that
soy protein (SP) is as allergenic as cow's milk (CM) protein citing a review paper[3]; however, the author failed to detail which are these studies.
In 1990 we demonstrated[4] that Eastham et al[5] have shown an antibody response to SPs in all SP-fed infants that was comparable to that found to CM in CM-fed infants. However, only soy antigenicity was studied,[4] since the authors measured not IgE antibodies but hemagglutinins to soy and to CM, which mainly belong to IgG antibodies.[5] As the
matter remained controversial, I have published a paper with 142 references and 7 tables, encompassing all diverse aspects of SPs.[6]
If Professor Salazar-De-Sousa reads attentively the data shown in the tables of the paper, he shall convince himself that SFs are recommended for the treatment and/or
prevention of food allergy, also following a recent document of the American Academy of Pediatrics.[7] However, we were distressed about the news "against soy formulas" that we read on the literature, such as "soy formulas should not
prescribed to allergic infants, due to the high incidence of
crossreactions with cow milk proteins".[8]
Professor Salazar, however, appears to be really interested in hydrolysate formulas (HFs). We have documented 202 reactions to HFs in a paper, and 41 case-reports in
another. In total 17 cases of shock-anaphylaxis (one every 3.3 years) versus one/22.3 years provoked by SPFs, with a difference of 676%.

I read with great interest a manuscript reported by Hodson et al in
the journal (2000;83:45-51. The authors discussed various corticosteroid
treatment protocols in patients with nephrotic syndrome (NS). They
suggested that children in their first episode of NS should be treated
with prednisone for at least three months with an increase in benefit being
shown for up to seven months of treatment.

treatment protocols in patients with nephrotic syndrome (NS). They
suggested that children in their first episode of NS should be treated

We used prednisone (daily 60 mg/m2 for 4 weeks, 45, 30, 20, 5 mg/m2 on
alternate days for 4 weeks, respectively) in the treatment of 7 patients
with NS (Group I) and compared its effect with the high dose
methylprednisolone (HDMP) in a dosage of 30 mg/kg/d for 3 days, 20 mg/kg/d for 4 days, 10 mg/kg/d for a week, perorally, before 9 A.M. in the
treatment of 8 patients with NS (Group II).[1]
The patients were followed-up for a duration of 38 ± 5.5 months (24-68
months) in Group I and 42 ± 5.5 moths (16-72 months) in Group II.
No
significant difference was obtained in the duration of remission between
two groups (p>0.05), while HDMP induced early remission than
prednisone (p<_0.05. the="the" mean="mean" relapse="relapse" rates="rates" were="were" _0.8="_0.8" year="year" in="in" both="both" groups.="groups." we="we" think="think" that="that" oral="oral" hdmp="hdmp" treatment="treatment" may="may" be="be" used="used" of="of" ns="ns" and="and" is="is" more="more" effective="effective" inducing="inducing" early="early" remission="remission" than="than" prednisone.p="prednisone.p"/>
Conclusion, it can be recommended that patients with NS can be treated
with the oral HDMP as an alternative treatment to standart oral
prednisone treatment.

First multiplying the probabilities gives the odds against these

Second she has calculated the a priori possibility for events that

The report of Hacking et al,[1] of a series of infants with very
early onset interstitial lung disease (ILD) with good prognosis, is of
great clinical interest but sadly represents a lost investigative
opportunity.
Firstly, their statement that percutaneous open lung biopsy
has fewer side effects than open lung biopsy (OLB) is not supported by any
direct comparative trial, and cannot be allowed to stand. Indeed, the
largest published series using this technique[2] was heavily criticized
both for the number of complications and the often non-diagnostic samples
obtained.[3,4] In contrast OLB is safe,[5] permits direct inspection of
the site of biopsy, and allows the acquisition of specimens large enough
to determine the lung architecture in order more precisely to classify the
different types of paediatric ILD. OLB thus allows appreciation of the
distribution of disease involvement within the acinus, allowing more
precise identification of different histopathological patterns. There is
thus no reason to favour percutaneous biopsy over OLB in skilled hands;
indeed the weight of evidence is in favour of OLB.
Secondly, their
selected nomenclature of paediatric ILD is open to criticism. It is
questionable whether the use of term "idiopathic pulmonary fibrosis" (IPF)
is still appropriate in children. IPF is generally used synonymously with
lone cryptogenic fibrosing alveolitis, which in adults is most often
represented histopathologically by the pattern of "usual interstitial
pneumonia" (UIP). However UIP is rarely if ever seen in children; much
more common are lymphocytic interstitial pneumonia (LIP), desquamative
interstitial pneumonia (DIP), non-specific interstitial pneumonia (NSIP)
and chronic pneumonitis of infancy.[6] Identifying these histological
patterns may point towards specific investigations with regard to
aetiology, and may also provide prognostic and treatment data, and we
consider that it is a pity that this or a similar histopathological
classification was not used in this report.
We suggest that more will be
learned about these rare conditions if diagnostic precision is maximized
by comparison of pre-biopsy computed tomography with properly classified
histological findings.[7] Inter-disciplinary collaboration is needed to
achieve this; and it is unfortunate that more details of imaging and an up
to date classification of histology were not included in an otherwise
informative paper.[1]

Although the paper of El-Radhi et al[1] presents interesting data about decreases in inflammatory markers during the resolution of acute asthma, some of their conclusions are not valid. First, acute asthma has a tendency to resolve without corticosteroid therapy.[2] Since all of the children with acute asthma (quite rightly) received steroids, the observed effect may equally reflect processes associated wit...

Although studies on children with petechiae who appear clinically unwell are important, the management of such children should pose few dilemmas in deciding to treat for presumed sepsis. A more challenging group is those with petechiae who appear to be well. We feel this group generates anxiety for clinicians who worry about missing occult or ear...
The recent article by Eiser and Morse was an excellent review of studies in this area.[1] We agree that emphasising the outcome of the child as a whole, rather than using raw clinical indicators is important, and that measuring Quality of Life (QoL) should help with this. The article refers to an instrument which we developed to measure QoL in children with Crohn’s disease.[2] The initial development actuall...
Dear Editor:
Partsch and colleagues speculate that a rise in testicular temperature in infants and young children consequent to the wearing of modern plastic lined disposable nappies [diapers] may have contributed to both the fall in sperm counts and the increase in testicular cancer which have been reported in some countries.[1] In support of this hypothesis Partsche et al refer to reports of rising incidence ra...
Dear Editor,
We thank David Strauss for his interest in our work but he fails to substantiate his claims that there are 'substantial problems' with it.
First, we wish to correct an error on page 470 (Arch. Dis. Child. 2000; 83: 470), column 2, line 11, `dying before' should read 'surviving until'.
With regard to Strauss's remarks on LAS, both the abstract and the results section include th...
Dear Editor,
We thank Dr Grigg for his interest in our work.[1] We agree that the asthma attacks may have resolved spontaneously in some cases, which was precisely why we stated that the markers fell in association with steroid therapy, and nowhere implied causality. Nevertheless, the statistical analysis suggests that the chances this occurred at random are extremely low.
We agree that corticosteroid...
Dear Sir
Professor Salazar-De-Sousa,[1] commenting on the recent paper by Høst et al,[2] maintains that recent prospective and randomised clinical studies have shown that soy protein (SP) is as allergenic as cow's milk (CM) protein citing a review paper[3]; however, the author failed to detail which are these studies.
In 1990 we demonstrated[4] that Eastham et al[5] have shown an antibody response to SPs in...
Dear Editor,
I read with great interest a manuscript reported by Hodson et al in the journal (2000;83:45-51. The authors discussed various corticosteroid treatment protocols in patients with nephrotic syndrome (NS). They suggested that children in their first episode of NS should be treated with prednisone for at least three months with an increase in benefit being shown for up to seven months of treatment.

Liz Donovan's fascinating article certainly suggests that the big finger is pointing at her. However, although her calculation is numerically correct (and how nice to find someone using non-US billions) the reasoning is a little suspect.
First multiplying the probabilities gives the odds against these seven rare conditions presenting in the order indicated; her final figure should be divided by 7...
Dear Editor:
The report of Hacking et al,[1] of a series of infants with very early onset interstitial lung disease (ILD) with good prognosis, is of great clinical interest but sadly represents a lost investigative opportunity.
Firstly, their statement that percutaneous open lung biopsy has fewer side effects than open lung biopsy (OLB) is not supported by any direct comparative trial, and cannot be allow...
