Sure enough, the association is positive and may be higher in those given \u201catypical\u201d antipsychotics. But this was no watertight study; medication was often given for a month or less and it\u2019s far from clear where, if at all, the relation was causal.<\/p>\n<p>\u201cPhysiotherapy\u201d for most of us doctors is a black box, and we want to keep it that way for fear that we might have nothing otherwise to offer our patients with subacute back pain. <a href=\"http:\/\/www.annals.org\/cgi\/content\/abstract\/146\/11\/787\">This study from Australia and New Zealand<\/a> attempted to prise open the black lid and see what\u2019s inside the box: it randomised patients to physiotherapist-directed exercise or sham exercise sessions plus physiotherapist-directed advice or sham advice. The canny Ozzies and Kiwis weren\u2019t supposed to know the difference. And actually there wasn\u2019t much at 6 weeks and none at all at 12 months, in terms of outcome.<\/p>\n<p>Here\u2019s a <a href=\"http:\/\/www.annals.org\/cgi\/content\/abstract\/146\/11\/797\">Japanese meta-analysis of a new marker for rheumatoid arthritis<\/a> \u2013 anti-cyclic citrullinated peptide antibodies. These antibodies may even be causal in the disease process. The editorial shows that their predictive value still varies with the clinical context, as is the case with all diagnostic tests. \u201cBayes clears the haze\u201d, it claims, but even a high risk patient with a clear clinical history and positive anti-CCP antibodies has no more than a 67% risk of having rheumatoid: quite a diagnostic sea-mist, I would say.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Another negative trial of homocysteine-lowering therapy: this is a substudy of HOPE-2 and shows that oral supplements of folic acid, pyridoxine and cobalamin lower HCy but do not reduce venous [&#8230;]<\/p>\n<p><a class=\"btn btn-secondary understrap-read-more-link\" href=\"https:\/\/blogs.bmj.com\/bmj\/2007\/06\/10\/ann-intern-med-5-june-2007-vol-146\/\">More&#8230;<\/a><\/p>\n","protected":false},"author":1,"featured_media":38363,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[111],"tags":[],"class_list":["post-250","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-richard-lehmans-weekly-review-of-medical-journals"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
