  • Are sleep studies worth doing?
    Steve Cunningham

    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...

  • Sweat chloride and conductivity
    Vicky A LeGrys
    Dear Editor

    As a principal author of the sweat testing document published by National Committee for Clinical Laboratory Standards (NCCLS) and consultant to the Cystic Fibrosis Foundation (CFF)(US), I write to address an inaccuracy in the article by Heeley et al (Indirect measurement of sweat electrolyte concentration in the laboratory diagnosis of cystic fibrosis. Arch Dis Child 2000;82:420-4). The authors misrepresent...

  • Iron deficiency anaemia, Helicobacter pylori infection and delayed pubertal growth
    L Cuoco

    Dear Editor

    We read with great interest the paper of Choe and colleagues who investigated possible relationships between H. pylori infection with iron deficiency anaemia (IDA) and subnormal growth at puberty.[1] They concluded that H. pylori infection and related IDA, rather than bacterial infection per se, might cause delayed pubertal growth. We believe that Choe et al’s results need some considerations.

  • Data presented do not justify pessimistic conclusions
    Charlotte M Wright
    Dear Editor

    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...

  • Growth monitoring
    David Morley
    Dear Editor

    Garner, Panpanich and Logan (Arch Dis Child 2000;82:197-201) presented a much needed review of growth monitoring. This is a component of primary health care on which so much finance and health workers' time has and is being expended. No doubt this review will stimulate more necessary trials.

    However, they did not touch on one important aspect of growth monitoring, that is whether health work...

  • Pyridoxine dependent and pyridoxine responsive seizures
    Daniel Hindley

    Dear Editor

    Seizures in infancy and early childhood responsive to pyridoxine are well recognised but rare. Baxter (1) has recently observed that "almost a third of neonatal cases of pyridoxine dependency present with apparent birth asphyxia and/or suspected hypoxic-ischaemic encephalopathy" and recommended that, because of the high proportion of atypical cases, "all children with early onset (younger than 3 years ol...

    VC Cappendijk

    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,

  • Factors delaying diagnosis of appendicitis in children
    Yim Yee Chan

    Dear Editor

    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...

  • Re: Consider absolute risks in SIDS prevention
    Peter Blair

    Authors response

    Poor postnatal weight gain was a significant factor in the multivariate analysis despite controlling for low birthweight, prematurity, neonatal problems, poor socio-economic status and many other potential confounding factors and remained significant when further highly predictive covariates of SIDS such as infants put down prone, infants found with head covered and tobacco exposure were added...

  • Recommendations or guidelines regarding MMR vaccination in children allergic to egg should be clear
    Cantani Arnaldo

    Dear Editor

    I thank doctors Lakshman and Finn for their kind reply, and recognise that my use of the word "hospital" has given rise to a misunderstanding. My letter was based on the analysis the authors have made, not in the ADC article,[1] but in their eLetter to BMJ.[2]

    They wrote:
    (1) immunisation with any vaccine in any child always carries a risk of potentially fatal anaphylaxis...
