  • The surgical safety checklist-mainly a challenge for anaesthesia mortality in low-income countries?
    Gregor Pollach

    Working on a daily basis in the theatres of the largest hospital in a low-income country (Malawi) we were pleased to read the study of Aveling and colleagues [1]. They demonstrated in a clear, quite comprehensive and critical manner challenges involved with the surgical safety checklist in resource poor situations.

    Continuously experiencing the real life situation in Africa we do think that there is an important...

  • UK study of SmPCs complements the findings of German study.
    David K Raynor

    Summaries of Product Characteristics (SmPCs) are a cornerstone of the EU medicines licensing process, and could be a valuable information resource for doctors and other health professionals. We welcome the paper by Vromans et al, looking at how SmPCs could better support physicians, and are pleased to say that their findings with German doctors, are consistent with the findings from UK doctors which we published contempo...

  • Data owner and pollen allergens in Denmark
    Janne Sommer

    Dear Professor Ping Qin, Dear Editor

    I have with interest read the article: Suicide risk in relation to air pollen counts: a study based on data from Danish registers. As the data producer and data owner I have identified a number of incorrect statements in this study, that I would like to see corrected or added. Due to these errors, the study is unacceptable both with respect to scientific practice as well as wi...

  • Re:Authors' Reply to responses on BMJ Open to Bed sharing when parents do not smoke: Is there a risk of SIDS? An individual level analysis of five major cases-control studies.
    Edward J. O'Hagan

    Language in and of itself has no meaning . Only people have meaning. For example:

    Through the Looking Glass, by Lewis Carroll

    'I don't know what you mean by "glory",' Alice said.

    Humpty Dumpty smiled contemptuously. 'Of course you don't --till I tell you. I meant "there's a nice knock-down argument for you!"'

    'But "glory" doesn't mean "a nice knock-down argument",' Alice objected....

  • Response from the European Medicines Agency
    Isabelle Moulon

    The European Medicines Agency (EMA) welcomes the research on the usability of the summaries of the European Public Assessment reports (EPAR summaries) by Professor David K Raynor and David Bryant recently published on the BMJ Open website.

    The EMA had first become aware of the results of this user-testing study in 2011 while the Agency was already consulting stakeholders on improving the EPAR summaries, aiming a...

  • Re:Response to 'Does contact with a podiatrist prevent the occurrence of a lower extremity amputation in people with diabetes? A systematic review and meta-analysis.' CM Buckley, IJ Perry, CP Bradley, PM Kearney
    Claire M Buckley

    Many thanks to the College of Podiatry and the Society of Chiropodists and Podiatrists for your response to our systematic review examining the published evidence for the effect of contact with a podiatrist on the occurrence of a lower extremity amputation in people with diabetes. We agree wholeheartedly that this review does not provide proof that podiatric intervention has no effect on amputation rates. Rather, it hig...

  • Re:The mortality and cancer experience of New Zealand Vietnam war veterans: a cohort study
    David I McBride

    Roy, If we saw worse mortality in this group, we would have a problem. We don't, we see the 'healthy soldier' effect. This probably means that the Maori men in our sample were as healthy as anyone else.

  • Response to "Specificity and sensitivity of transcranial sonography of the substantia nigra in the diagnosis of Parkinson's disease: prospective cohort study in 196 patients"
    Philipp Mahlknecht

    The study by Bouwmans and colleagues seems to be well designed and thoroughly executed [1], but the primary results are surprising regarding both the transcranial sonography (TCS) and dopamine transporters - single- photon emission computed tomography (DAT-SPECT) results. According to large scale prospective studies, DAT-SPECT should have a specificity close to 100% in differentiating neurodegenerative parkinsonian syndrom...

  • Complementary and alternative asthma treatments and their association with asthma control: a population-based study: Letter to Editor
    Simran Kaur

    The use of complementary and alternative treatment in asthmatic patients was very well described by Chen et al. It is indeed a good piece of research wherein relationship of different types of CAM is done with asthma severity and treatment by conventional medications. However, it is also important to estimate the therapeutic-toxicologic safety profile (risk-benefit ratio) of various CAM interventions for asthma 1. Also,...

  • Differences between RCTs and observational studies of hormone therapy effects have not been definitely reconciled
    Arthur J Hartz

    Rossouw et al. addressed only the comparisons of results from randomized controlled trials (RCTs) and observational studies (OSs). They did not consider analyses that compared outcomes of participants who had the same treatment but were in different studies. These analyses found that adjusting for the WHI risk factors was not sufficient to account for unmeasured risk differences between subjects in different studies. T...
