  • The linear regression model
    Michael JR Healy

    Dear Editor,

    There are several problems associated with the use of multiple regression, but the concerns raised by Dr Narchi (Letters, June 2007 p 559) are happily baseless. There is no assumption in the technique of non-association between the predictor variables – indeed, the method is often used to elucidate the effect of one predictor corrected for the confounding effect of another which is associated with...

  • The Formula (Age x 3) + 7, Is A More Accurate Estimate Of Weight In Children.
    Talat Mushtaq

    Dear Editor,

    We read with interest the article by Luscombe and Owens (1) who present a potentially more accurate formula (Weight (kg) = (age x 3) + 7) for estimating a child’s weight based on their age derived from the weights of children attending an emergency department at Nottingham. The most familiar method to estimate the weight is based on the formula: Weight = (Age + 4) x 2, as widely taught in the Advanced...

  • Surprised!
    VIJAY PALANIVEL

    Dear Editor,

    The initial blood gas that was mentioned (pH-6.9, pCO2-11 & BE 12.8) was interpreted as severe metabolic acidosis. But this is in fact, combined respiratory and metabolic acidosis. The 2 possible differentials from the CXR are pneumothorax and cystic congenital adenomatoid malformation. In such a respiratory compromise (as evident from the blood gas) and a CXR picture, I am surprised that this...

  • Response to: Should paediatric central lines be aspirated before use?
    Jonathan HC Evans

    Dear Editor,

    Drs Coulthard & Skinner are correct to highlight the potential dangers of clot embolisation from paediatric central lines. There is however an equally strong argument for aspiration the lines to remove heparin and prevent inadvertent systemic anticoagulation [1,2].

    Haemodialysis lines in particular have relatively large volumes in comparison to patient size and it is not uncommon to have a...

  • Embracing breastfeeding automatically places us on the right side of history
    James E Akre

    Dear Editor,

    The Perspective on the paper by Akobeng and Heller is appreciated, as indeed is the paper itself. Both contribute convincingly to our collective awareness of breastfeeding’s centrality to human development. However, I’m concerned about communicating the benefits of breastfeeding without also making parents, health professionals and policy-makers aware that artificial feeding is a harmful practice with serio...

  • Blood pressure centiles for Great Britain – Can they be safely applied to clinical practice?
    Anjum Gandhi

    Dear Editor,

    The study by Jackson et al(1) attempts to fill a gap in our knowledge in a very vital area. Paediatricians in the United Kingdom have traditionally not included a blood pressure measurement as part of routine clinical assessment, as hypertension is not generally considered to be a common paediatric problem. Those who did check BP had to rely on normal values derived from European and North American stud...

  • Blood pressure charts in UK children
    Kjell Tullus

    Dear Editor,

    The study by Jackson et al on blood pressure centiles for Great Britain (1) provides us with valuable information and insight into children’s blood pressure centiles measured on automated monitors. This is the first time we have been able to see normative data for such large numbers of children in the UK.

    There are, however, a few things in this publication that we would like to discuss. It is...

  • Underestimation potentially better than overestimation
    Mark Anderson

    Dear Editor,

    Luscombe and Owens (1) propose a new formula (weight(kg)=3(age)+7) for accurately estimating weight in the 21st century child. They point out that the classical formula (weight(kg)=2(age+4)) underestimates actual weight in the majority of cases and that this has implications for potentially underdosing of resuscitation drugs and fluids. One of the factors implicated by the authors in this increase in we...

  • The social facilitation of food intake- A recent experience
    Rajalakshmi Lakshman

    Dear Editor,

    In your May 2007 Edition we read with interest three original articles relating to childhood nutrition and obesity (1-3). This highlights the importance of this topic and the necessity to take practical steps to address the problem. Lumeng and Hillman (1) observed food consumption in 54 preschool children in a group of three or nine children and conclude that children consumed 30% more food when e...

  • Cystic lung lesion, a nasogastric tube and plain chest x-ray
    Aruna B Abhyankar

    Dear Editor,

    I read with interest the report of late presentation of congenital diaphragmatic hernia. The authors report that after initial chest xray a ct scan was performed and then followed by another ct scan with contrast via NG tube.

    The rare presentation of diaphragmatic hernia as a solitary cystic lesion may led to a dealy in diagnosis and at times insertion of chest drain. However, it is a we...
