  • Author's comments: Could exposure to passive smoke vary with wine consumption?
    Alberto Ruano-Ravina

    Dear Editor

    We agree with Dr Anderson in that patterns of alcohol consumption may vary amongst social class. Nevertheless, in our investigation, most of the people were of low-middle social class. In Spain it is possible that, independently of the economic position, people can have the same access to alcohol since it can be obtained at various prices (from 1€ per bottle to 20€ or more for red wine). The same is...

  • Could exposure to passive smoke vary with wine consumption?
    Wendy J A Anderson

    Dear Editor

    I read with interest the article by Ruano-Ravina et al. Several studies have suggested a relationship between alcohol intake and lung cancer prevalence but existing literature is contradictory. This paper offers an explanation, suggesting that the type of wine, and more specifically whether it is red or white, determines whether the effect is protective or detrimental. There is evidence tha...

  • Discussion "Consumption of milk fat and reduced asthma risk in pre-school children"
    R.M.D. Bernsen

    Dear Editor

    With interest I read the discussion between Karmaus et al. and Wijga et al. [1] Wijga et al. rightly point out that "parental atopy" is a confounder according to figure 1, which illustrates the situation that families with a history of atopy tend to adhere to special diets (for instance avoidance of cow’s milk). In this situation it is correct to include "parental atopy" in the model...

  • B-cell non-Hodgkin's lymphoma of trachea mimicking COPD
    Andrew RL Medford

    Dear Editor

    I was very interested in your recently published image and case describing a patient with COPD presenting as an exacerbation but found to have a B cell non-Hodgkin’s lymphoma of trachea.[1] I wondered whether an FEV1 had been performed on admission and what the Empey Index (FEV1/ PEF ratio) of the patient had been as if this had been high (greater than ten), it may have suggested not simply another...

  • PEF or FEF 75% in asthma management?
    Fabrizio Della Torre

    Dear Editor

    We have read with interest the two papers published by Reddel H K et al.[1] and Ruffin R [2] on the usefulness of the best PEF for asthma self -management plans.

    On the basis of our own experience, we would like to add several comments and raise the following two questions:
    Have you also considered the forced expiratory flow (FEF) at 25–75 of forced vital capacity in...

  • Delayed Neutrophil Apoptosis in Newborn Infants
    Sailesh Kotecha

    Dear Editor

    We would like to thank Dr Molloy for her interest in our recent paper showing delayed neutrophil apoptosis in infants who progressed to chronic lung disease prematurity (CLD) and indeed in those infants who do not survive their course of extracorporeal membrane oxygenation (ECMO) for severe respiratory failure.[1] Having established the association, we are now exploring the potential mechanisms that mi...

  • Authors' response
    K F Chung

    Dear Editor

    We thank Professor Morice and his colleagues for their interest and for the issues raised vis-a-vis our manuscript.

    The main issue raised concerns the possibility that we may have missed gastrooesophageal disorders such as reflux and dysmotility in our cohort of chronic cough patients. In our assessment protocol, we state that we used oesophageal pH measurements in most patients (32 out of 50)...

  • COPD, restrictive syndrome and inflammation
    Filippo Fimognari

    Dear Editor

    in a recent issue of the Journal, Gan WQ et al. published a systematic review and meta-analysis of 14 reports which confirmed the strong association between COPD and biological markers of systemic inflammation [1]. In 6 reports, COPD was diagnosed according to the presence of a FEV1/FVC ratio lower than 0.7. However, in the remaining 8 studies this measure was not available, and authors assumed as affecte...

  • Authors' reply
    Niels Seersholm

    Dear Editor

    Morten Dahl and Børge G. Nordestgaard argue against selection bias, if genotyping is performed after lung function tests because a newborn with PiMZ genotype does not change to PiZZ later in life. The latter is obviously true and not the issue. The reason for possible selection bias is that some persons may fail to have genotype performed due to a characteristic of the lung function tests under stud...

  • Tuberculosis and anti-TNF- treatment
    Prasanta Raghab Mohapatra

    Dear Editor

    Anti TNF treatment should be given after screening for latent tuberculosis as this may result active tuberculosis in these cases [1]. The World Health Organization estimates that at least one-third of the world’s population are infected with TB [2], [3]. 95% of tuberculosis cases and 98% tuberculosis deaths are in the developing countries [2], [3]. It is difficult to rule out latent tuberculosis infection...
