  • Erratum for BMJ 2014-006608
    Pauline Bakibinga

    Dear Editor in Chief-BMJ Open,

    Figures 3 and 4 in the above publication are misplaced and marked with the wrong captions What is Figure 3 should be Figure 4 and Figure 4 should be Figure 3.

    The right captions would then be: Figure 3: Summary of the PAMANECH Intervention (in blue)

    Figure 4: PAMANECH Project Data collection plan (table in black and white).

    Kind regards,

  • Supervised Learning Events: is rebranding enough?
    Jason M Ali

    Dear Editor

    I read with great interest the article by Rees et al (1) which represents the first assessment of trainee and trainer perceptions towards 'supervised learning events' (SLEs). The Foundation Programme in the UK has been pioneering in its transition from 'workplace based assessments' (WBAs) to SLEs, with the aim of emphasising the formative intent of the tools, to improve engagement of trainees with th...

  • Nalmefene: Extrapolation, Exaggeration or Evidence Based Medicine?
    Alain Braillon

    How Lundbeck's conclusion "Nalmefene can be seen as a cost-effective treatment for alcohol dependence, with substantial public health benefits" can have been published?(1) Should "Open" in BMJ Open means open to aggressive marketing from the drug industry, open not to hope but to hype, open without proper discussion despite several gross limitations.

    First, the piece apply a mathematical model to three trials tha...

  • Why exclude adverse events possibly due to medication or to some procedure?
    Andrew Herxheimer

    This protocol is enterprising, interesting and important, but it nowhere refers to adverse events that might be effects of medication, or of failure of a medicine to work.

    Research on 'patient safety' in hospital has developed quite separately from pharmacovigilance and the elucidation of harms possibly caused by medicines and their prevention, but they are related both conceptually and in practice. They need...

  • Response to the comments published by Pruthu et al.
    Jakob Virenfeldt

    Thank you for your comments on the published paper.

Patients with smear negative TB are diagnosed at the national TB hospital upon x-ray and physician consultation, and are also f...

  • Reply to Rydahl and Clausen
    Oejvind Lidegaard

    Rydahl and Clausen are right about problems with the validity of some official statistics published by central institutions or on the home page of the State Serum Institute (SSI). These processed data are, however, not the same as raw data from the Danish Birth Registry (DBR).

    Today, official statistics are typically made by data managers in severely understaffed units in our central administration, often without...

  • Data in the National Danish Birth Register are unreliable.
    Eva Rydahl

    Olsen (1) has questioned the validity of the stillbirth data used in Hedegaard et als study based on The Danish Birth Register (DBR). Lidegaard replies that "We always make our own data retrieval from the raw data in the National registries, including the birth registry rather than relying on the official statistics" (2). However, we are concerned that data in DBR seems very unreliable, and perhaps even compromised....

    Jens C Skogen

Ung@hordaland, a population-based study" BMJ OPEN 2014;4;e005357.

  • BCIS in hemiarthroplasty
    Anoop G. Jose

    We found this to be an interesting and thought-provoking article about a relatively less known condition, bone cement implantation syndrome (BCIS).(1) There are clear advantages and disadvantages to the use of cement in hemiarthroplasty, and this data illustrates the infrequent incidence of BCIS whilst emphasising the ever-present risk of serious harm to the patient. As such, it should be worth mentioning the risk of BCIS...
