  • Patients still not taking analgesia before attending accident and emergency department
    Arif Razak

    Dear sir

    I was working at a A&E department in North West few years ago and had similar questions as to why patients not taking any analgesia before attending the department. I did a survey on this matter and this is the result of the survey.

    Objectives

    To determine the percentage of patients attending the accident and emergency department with pain but without taking any analgesia prior t...

  • Re:Effects of bed height on the performance of chest compressions- Clinical application of results
    Je Hyeok Oh

    We are incredibly glad to hear that Dr. Sherren has taken an interest in our research (1). I concur with his position on this matter. I believe that cardiopulmonary resuscitation (CPR) issues in in-hospital cardiac arrest patients will be solved through near future technologies such as extracorporeal membrane oxygenators. However, if we divide cardiac arrests broadly into in-hospital and out-of-hospital, or on-site arrests...

  • Intravenous lipid emulsion for calcium channel blocker overdose: fattening up the treatment
    Theophilus L Samuels

    We read with interest the case report by Abeysinghe and colleagues reporting hyperinsulinaemic euglycaemic therapy (HIET) in the treatment of a patient presenting with persistent hypotension following an overdose of the lipophilic calcium channel blocker diltiazem.[1]

    Diltiazem is extremely lipophilic with a log P value of 4.53 (a measure of lipid solubility). Thus we consider that it would have been amenable t...

  • Triage system and adherence of nurses
    Jean-P Tourtier

    We would like to thank van Veen et al. for their evaluation of the Manchester Triage System (MTS) in children. This study was based on simulated case scenario to investigate the repeatability of triage, with a total compliance of nurses with the MTS. We would like to highlight that in real life experience, strict adherence of nurses to triage protocol is rare. Wacher et al. (evaluating the implementation of a set of stan...

  • Normalization of ischemia modified albumin results for serum albumin.
    Giuseppe Lippi

    Ischemia modified albumin (IMA) has recently been proposed for the early detection of myocardial ischemia without infarction [1]. We read with interest the article of Ming-Hui Lin, who evaluated this marker as an early negative predictor of acute coronary syndrome (ACS) in different time to presentation groups and different cardiac risk groups [2]. The authors asserted that IMA is a relatively new test, performed on diffe...

  • Nail polish and pulse oximetry
    Jochen Hinkelbein
    To the Editor!

    We have read the original contribution by Sutcu Cicek et al. [1] with high interest regarding the effect of nail polish and henna on pulse oximetry readings. In their study, these authors report on the influence of both factors in 33 normoxic healthy females. Although the study is interesting, it has significant limitations, which must be addressed.

    To our surprise, the authors state, it is not proven tha...

  • Is S100-B better then rolling a die?
    Steve W Goodacre

    Muller et al report that S-100B had a specificity of 12.2% and a sensitivity of 86.4% and conclude that use of serum S-100B as a biomarker for CCT triage may improve patient screening and decrease the number of CCT scans performed. However, if we were to roll a 6-sided die and call the number 6 negative and the numbers 1 to 5 positive we would expect to have a test with similar parameters: 83.3% sensitivity (i.e. positiv...

  • Response to: Survival after cardiac arrest and severe lactic acidosis (pH 6.61) due to haemorrhage.
    Harvey J Pynn

    Dear Sirs

    I read, with considerable interest, your case history of a 21 year old man who was stabbed in his buttock and went on to suffer a hypovolaemic cardiac arrest whilst on the emergency unit ward awaiting transfusion and exploration of the wound under general anaesthesia.

    A pH of 6.61 is undeniably low and had he presented at such extremes of physiology to your Emergency Department his outcome wo...

  • The good and the harm.
    michel g soete

    The principle of 'primum non nocere' stems from the ancient world of Plato. In the 'real' world it is immpossible to act without doing harm. An examination or treatment takes always some time and money from the patient. Taking time and money is the minimum harm that is done. In many cases ther is additional harm.

    Therefore the principle 'doing more good than harm' seems at first sight a better and more realistic...
