Carter and Syed-Sabir1 gave a good account on the utility of rating
scales in ADHD. The time was appropriate when the new NICE guidance was
published. 2. However, I wish to emphasise to the readers that in UK, many
centres use the short version of Conners' Rating Scales- Revised (CRS-R).3
There are significant differences between the short and long versions of
the CRS.4 The Cognitive Problems / Inattention subscale on the teacher's
short CRS-R includes five questions as below:
Question No 4. Forgets things he/she has already learnt.
Question No 8. Poor in spelling.
Question 13. Not reading up to par.
18.Lacks interest in school work.
22. Poor in arithmetic.
All the above questions are related to the literacy difficulties rather
than indicating inattention. Therefore a high score in Cognitive Problems
/ Inattention subscale in the teacher's completed short CRS-R indicates a
child's literacy difficulties and not inattention. Clinicians need to be
aware that short CRS-R completed by teacher should not be used to evaluate
inattention in a child.

If authors are forced to use an example from a different patient it
would have been appropriate to acknowledge this.
These criticisms apart I enjoyed this Education section very much.

The review of Guillain-Barre Syndrome (GBS) (Arch Dis Child Educ
Pract Ed 2007; 92: ep161-ep168) was clear and comprehensive and will be of
practical value to all who manage these children, whether or not they are
admitted to an intensive care unit. The authors appropriately address the
important issue of communication and emphasise that this may be very
difficult if not impossible for the child and young person who is
conscious but unable to speak or move. Readers my find it interesting and
useful to learn about the often ingenious ways that a number of these
young people have used to ‘communicate’ in this situation, and it is often
not until later that these methods, together with other thoughts, can be
articulated 1,2.
At the Royal Liverpool Children’s Hospital (Alder Hey) we have
designed a single Integrated Care Pathway document which has replaced the
child’s medial case notes and is used by all medical, nursing and therapy
professionals involved in the management of patients with GBS wherever the
child is seen within the hospital (submitted for publication). One of the
main advantages of this single care pathway document is that it has
facilitated communication and knowledge-sharing between the many
disciplines involved with these children. A future version of this GBS
pathway will include a communication sheet for the family and, where
appropriate, the child.

Although examples of interstitial lung disease such as diffuse alveolar
haemorrhage and interstitial fibrosis were the only ones acknowledged to
be associated with Henoch-Schonlein purpura(HSP) in a recent review(1),
the association of HSP and pan-acinar emphysema attributable to alpha-1
antitrypsin(AAT) deficiency also deserves mention(2), especially in view
of the speculative relationship between anti neutrophil cytosplasmic
antibodies(ANCA) and AAT deficiency, on the one hand(2), and ANCA vs HSP
on the other(3)(4). Although the precise pathogenic basis of the
association of AAT deficiency and the vasculitides is unclear, according
to a recent evaluation a major role of alpha-1 antitrypsin(AAT) is to
inhibit the destructive capabilities of proteinase-3(PR3), the serine
protease released from neutrophils and monocytes at local sites of
inflammation and tissue injury. Deficiency of AAT results in an increase
in blood levels of free and active PR3 which, in turn generate further
tissue injury and also generate an antibody response in the form of ANCA.
ANCA, in turn, compounds PR3-related vascular injury by generating a
cascade which includes activation of tumour necrosis factor(TNF)-primed
neutrophils, accelaration of apoptosis of TNF-primed neutrophils, and
secondary necrosis of the TNF-primed neutrophils themselves. The premature
release of the toxic contents of the apoptopic cells is a further episode
in the catalogue of ANCA-related tissue destruction.(2). In the clinical
context a literature review revealed six cases of the association of AAT
deficiency and HSP, one being a child aged 1.8 years when first reported,
and the other five being adults aged 27-82. In the paediatric case there
was no documentation of lung disease, and, in that instance, chronic renal
disease was the significant complication of AAT deficiency. Among the five
adults, four had documented pan-lobular emphysema, with co-existing
chronic renal disease in three of those four. The one adult in whom
pulmonary status had not been documented did also have chronic renal
disease but the fourth adult with pan-lobular emphysema only experienced
transient proteinuria and transient haematuria(2). In the latter instance,
HSP was associated with ANCA of the Immunoglobulin G(IgG) subtype(5)
whereas, among the three adults in whom pan-lobular emphysema co-existed
with chronic renal disease, the one patient with ANCA was characterised
by the IgA subtype of ANCA(2). In all, ANCA was present in only two of
the 6 patients characterised by the association of AAT deficiency and
HSP(2). Both had pan-lobular emphysema, but only one had chronic renal
disease. ANCA of the IgA subclass was a feature of the patient with
chronic renal disease(2), and ANCA of the IgG subclass charcterised the
patient who was free of chronic renal disease(5). Although IgA ANCA has
been identified in as many as 82.3% of 35 chidren aged 3-16 in the acute
phase of HSP(3), among 28 consecutive adult HSP patients who presented
predominantly with abdominal symptoms, the prevalence of ANCA(subtype not
stated) was only 32.1%(4). In the former, no relationship was found
between severity of HSP and IgA ANCA(3), but in the latter HSP patients
with ANCA had significantly(p=0.02) higher clinical scores, significantly
higher(p=0.01)serum creatinine levels, and significantly(p=0.03)higher 24
hour urinary protein excretion than their ANCA negative counterparts(4)
However, given the variability in prevalence of ANCA in HSP patients free
of AAT deficiency(3)(4), and the low prevalence of ANCA when HSP is
associated with AAT(2), the role of ANCA, though speculative, nevertheless
remains intriguing, especially in view of the theoretical considerations
evaluated by Patterson et al(2).

We found Lio’s paper on alopecia in children (Arch. Dis. Child. Ed.
Pract., December issue) very interesting, but noticed that the author does
not mention celiac disease among the autoimmune diseases associated with
alopecia areata.
Both thyroid dysfunction and alopecia may point to celiac disease
even in the absence of gastrointestinal complaints.[1, 2] Alopecia areata
is in fact significantly associated to celiac disease in children as well
as in adults; it might even be its only manifestation, as reported in
several papers.[1, 3, 4] In these cases full recovery with hair re-growth
may be achieved on a gluten free diet. [3, 4] Moreover, we have previously
demonstrated that when associated to celiac disease, alopecia is one of
the autoimmune disorders apparently related to the duration of exposure to
gluten.[5]
We are therefore convinced that all children with alopecia areata
should be screened for celiac disease, particularly (but not exclusively)
if thyroid dysfunction is present.

We read with great interest the paper by Shaw “Osteoporosis in
pediatrics” (Arch. Dis. Child. Ed. Pract., December issue).
The author doesn’t cite celiac disease as a specific cause of osteoporosis
in children, although he correctly recommends celiac screening in case of
suspected secondary osteoporosis.
A diminished bone mineral density with z score lower than -1.0
standard deviation (SD) can be found in up to 50% of children with celiac
disease; more severe reduction of mineral density with z score lower than
-2.5 SD is generally observed only in newly diagnosed children or in
adults.[1] Moreover, celiac patients, including children, are at increased
risk of hip fractures and fractures of any type.[2]
Osteoporosis in celiac disease may be due not only to malabsorption,
but also to abnormalities in cytokine levels.[3] Increased levels of
osteoclast-triggering cytokines, such as IL-1, IL-6 and TNFalfa, have in
fact been found in untreated CD patients, while the level of inhibitory
cytokines such as IL-18 and IL-12 may be lowered. Normalization of
cytokines levels with a gluten-free diet may explain the increased bone
mineral density observed in osteopenic celiac children, particularly under
4 years, while this effect is not so obvious in adults. [1, 4] As bone
mineral density can be reduced both in symptomatic and in silent celiac
disease, early diagnosis is important not only in order to achieve a
normal bone mineral density, but also to prevent the onset of autoimmune
conditions associated to celiac disease.[5]
In conclusion, osteopenia and osteoporosis may be the only
manifestation of silent/latent celiac disease, leading to an increased
risk of fractures. Given the high prevalence of celiac disease, and the
effectiveness of a gluten-free diet in treating and preventing its
complications, it is relevant to consider celiac disease in the
differential diagnosis of osteoporosis in pediatrics.

Alopecia may also be attributable to the use of hair relaxants such
as sodium hydroxide and guanidine hydroxide, respectively(1) or other
products containing sodium, potassium, or guanine sulfites or
thioglycolates(2) to straighten or "relax" tightly curly(spiral) black
hair of the type found among South African blacks(1) or African-
Americans(2). These products work by rearranging the cysteine disulfide
bonds of the hair, but an undesirable consequence is to damage the hair
shaft and to decrease its tensile strenghth(3). In one South African study
in which the definitive analysis comprised 1020 subjects aged 6-21,
alopecia was significantly(p < 0.0001) more prevalent among those with
"relaxed" hair than among those with "natural" hair(1). In an American
study, as many as 95% of 464 patients suffered hair breakage and hair loss
after using a hair relaxant(4) which was subsequently withdrawn after
intervention by the United States FDA. Chemical relaxants can also cause
scarring alopecia, exemplified by 5 subjects in whom the initial symptom
was onset of head discomfort within minutes of the application of the hair
relaxant. The vertex of the head was involved, and it healed with
scarring(5). Given the fact that hair relaxants have been used on children
as young as six(1), hair relaxant-related alopecia should enter into the
differential diagnosis of alopecia in children of African descent.

Dr Roberts questions the point of treating warts and molluscum which
are benign and will often spontaneously resolve, and expresses concern
about discussing these methods of treatment at all. In terms of the
former, I regret that I did not more explicitly state that the so-called
"tincture of time" is, by far, the preferred method of treating these
lesions. The focus of the review is on those cases where there is a
compelling reason to seek further treatment, with emphasis on sorting
through the vast (and often anecdotal) literature on these treatments.
As Dr Roberts notes, the consultant dermatologists carry a heavy load
in the UK, and this is perhaps equally true in the US.[1] Ironically, it
was the tremendous number of "emergency" consultations that are referred
to our practice for warts and molluscum that prompted me to write this
article. Many patients are referred by their pediatricians for warts and
molluscum that have persisted or are spreading, causing a great deal of
anxiety and frustration for all parties. Importantly, many of these
patients express anger towards their pediatrician and frequently feel
marginalized because they were told the lesions would go away without
treatment. Sometimes, the children are ostracized from school, public
pools or sporting events, adding psychological stress to the entire
family.[2]
Much more concerning, however, is when doctors or the patients
themselves feel compelled to treat these lesions and do so in ways that
may cause harm. I specifically cautioned against using imiquimod for
molluscum, for example, as I have seen many adverse effects when used for
this purpose. I have seen patients apply powerful acids and create
painful ulcers which scar, and have seen children traumatized by curettage
without anesthesia of any sort. The secondary purpose of the paper, then,
is to discuss these methods openly and without bias, so that if treatment
is deemed necessary, there is some context and experience for choosing an
appropriate treatment in a manner that is safe for the patient.
Drs Goodyear and Taibjee raise concern that I impugn evidence-based
medicine (EBM). In fact, in my five-page paper with almost 50 references
from the peer-reviewed literature including heavy reliance on the Cochrane
Database, I sought to explore the area where there is not yet enough
evidence to make easy rational choices about treatment of these skin
diseases. Indeed, on the British Association of Dermatologists website,
the only treatments that were given the strength of evidence D ("There is
fair evidence to support the rejection of the use of the procedure") were
oral cimetidine and homeopathy.[3] There were no treatments given
strength of evidence E ("There is good evidence to support the rejection
of the use of the prodedure"). In fact, two of the treatments I discussed
(imiquidmod and heat treatment/balneotherapy) were deemed to have
insufficient evidence at this time. As a strong proponent of EBM, I try
to remain vigilant for the fallacy of argumentum ad ignorantiam in all its
forms, which in this case might be best put: "absence of evidence is not
evidence of absence."
In sum, I overwhelmingly agree with the comments of Drs Goodyear,
Taibjee, and Roberts and appreciate the opportunity to put the review in a
proper light.

What messages are conveyed in this review of North American practice
to Paediatricians and General Practitioners in the UK? The high prevalence
of these conditions in school age children is well known, as is the
natural history for them to spontaneously resolve without medical
intervention. Are we now expected to routinely offer treatment advice or
even refer affected children to dermatology clinics? It would be helpful
to know if the recommendations contained in Dr Lio’s guide had the general
support of the British Association of Dermatologists. (2.)
The questionable benefits to the child of removing warts and
molluscum have to be balanced with the disadvantages of discomfort,
psychological trauma and the possibility of permanent scarring. Most
children prefer not to undergo such procedures if given the choice even
though their parents may wish us to adopt a more active cosmetic approach.
In support of the no treatment option, we should also consider the
practicalities of providing a clinical service for inessential treatments.
Consultant Dermatologists in the UK already carry a heavy patient load and
their expertise should perhaps be restricted to the assessment of lesions
which cause occasional diagnostic difficulty. Inflamed and irritated
lesions are best managed by treatment of the associated eczematisation
which can usually be achieved in primary care. Hospital paediatric
services do not normally have staff who are trained in minor skin surgery
or dermatological procedures so that patients referred for such treatments
would perhaps languish on a waiting list for several months until their
lesions spontaneously resolved.
Several helpful information leaflets are in general circulation to
guide parents and their doctors with general advice on benign
dermatological conditions in children. (2.3.4.) this should be the first
stage and often the only stage required in management.
