  • Pain
    peggy lreager
    Dear Editor,

    I ran across your site concerning glucomine and sulphate knee cream. I took a cruise to Mexico and bought some cream there with glucomine and sulphate for 6.00. I am 65 and I have rheumatoid-osteoarthritis and am in pain

    That cream worked for me but I cant find it anywhere here. Can you help me find it please?

    Thank you,

    Peggy

  • What is evidence-based medicine?. A note from a developing country
    Luis Huicho

    Dear Editor,

    I read with optimism the note from Dr. Glasziou. It is encouraging to know that systematic reviews on diagnostic tests are being considered as part of national Cochrane movements. We badly need them. We have been involved in this task ever since 1995 and published two systematic reviews [1,2]. Quality of primary studies and methodological problems need to be studied and new tools need to be developed....

  • The context of the test alters the significance placed upon the result
    David Bossano
    Dear Editor

    I see many results in which potassium falls (a little) above the normal range.[1] I was wondering at what level I should be concerned about sudden death being the presenting symptom.

    I reflected that the context in which the result was found affects my decision making.

    A routine test which identifies a raised value, is less alarming than a test which is done for a reason, such as the presence of s...

  • Topical chrondroitin and glucoseamine
    Sidha. S Sambandan

    Dear Editor

    Shouldn't the RCT be done in such a way that the placebo also has Camphor and peppermint oil in identical concentration to the actual cream?[1] It is already known that the latter two can have a good effect on osteoarthritis, especially in the elderly.

    Reference

    1. Reginster J-Y. A topical cream containing glucosamine and chondroitin sulphate reduced joint pain in osteoarthritis of...

  • This article is not about the real cervicogenic headache
    Celio Levyman MD MSc

    Dear Editor

    The paper in question has a strange problem: the definition of cervicogenic headache. Reading the text, one must look to all headaches that origins itself in cervical region, and there we have a conflict with International Classification of Headaches: first described by Ottar Sjaastad in late 1970s, the most correct assumption of cervicogenic headache is a particular syndrome who origins the pain in C...

  • Pragmatic Criteria for excluding diabetes in borderline patients
    David Bossano

    Dear Editor

    In our primary care practice we are grappling with the diagnostic criteria for (type II) DM.

    We use FPG as our main investigation with the WHO criteria of FPG <7.0 on two occasions defining diabetes.

    In the event of repeated FPGs between 6 and 7 (& presumably a previous RPG 7-11.1) we have previously referred patients for an OGTT. However, we have found that this often does not lead to...

  • Conclusion not supported by underlying data
    Brian S. Alper

    Dear Editors

    This Cochrane review concluded that antibiotics reduce short to medium-term persistence in children with persistent nasal discharge or older children with radiographically confirmed sinusitis.

    The EBM synopsis concluded that antibiotics are more effective than placebo in children with persistent nasal discharge.

    The 6 RCTs reviewed in the Cochrane review include four RCTs of older ch...

  • Wearing elasticated stockings on long haul flights
    Dawn McDonald

    Dear Editor

    I found this article interesting on the debate whether the benfit of wearing elasticated stockings on long haul flights were useful in prevention of DVT's in passengers. As you questioned the small amount used in the study were not significant therefore inconclusive on recommendations.

    I was wondering how the staff, namely the pilots cope who make more regular long haul flights than the passeng...

  • Apparently ventilation tubes give immediate hearing
    Moghira Iqbal Siddiqui

    Dear Editor

    Regarding the article by Michael B Aldous,[1] I was little concerned about the impression I got from the randomized control trial. I ask them to consider the proven fact that immediate hearing improvement that takes place following placement of ventilatory tubes. Is it not a fact that fluid accumaulation in middle ear results in profound hearing loss? Does the modern formulas calculating significance and po...

  • Are chest X-rays needed to diagnose pneumonia?
    Santabhanu Chakrabarti

    Dear Editor

    The question asked in a recent article[1] was “In children with acute respiratory infection, is tachypnoea accurate for detecting pneumonia?” The answer obtained was “in children with acute respiratory infection, tachypnoea had a sensitivity of 74% and specificity of 67%”. Please note that radiographic determination of pneumonia was the reference standard to which the finding of tachypnoea was compar...
