Mike and James ‘celebrate’ their 100th episode by scouring the world for insightful commentary and therapeutic gems and bring them to you in a hodgepodge of a podcast. The bottom line – we wish to thank you for listening, we hope our rantings have improved your practice in some way and that you stick with us as we enter the next century of TEC podcasts.
In episode 99, Mike and James shed light on two useful new trials. We breath air into what to do with patients with asthma who don't respond completely to inhaled corticosteroids and we take a close look with improved visual acuity at the microvascular data from ACCORD.
Mike and James were down in New Zealand the first week of September, Christchurch in particular, to give a presentation at the Royal New Zealand College of General Practitioners Annual Scientific Conference – “Doing the Right Thing'.
In episode 98, James and Mike delve into the world of asthma and leave the audience breathless with anticipation. We discuss what you do if inhaled corticosteroids don’t work completely and the risk of using LABAs on their own. Close to the end of the podcast James develops an acute asthmatic attack and Mike ‘accidentally’ gives James the wrong direction to the emergency room.

In Episode 97, Mike and James present listeners with 4 ‘diamonds in the rough’ which should have an impact on practice, or at least get you trending towards a change. Information on MMR and autism, metformin and Vit B12, HbA1C not being zero, and low dose colchicine are presented with the usual clarity and profoundness listeners have come to expect from the podcast. At the end we refer people to the show notes to clear up all the misinformation presented.

In episode 96, Mike and James continue on with the discussion around evidence for low back pain treatment. They discuss things like traction, heat, exercise and bedrest and then finally get into drugs – not personally of course, at least not much, but into the discussion of which ones work and by how much. We conclude with an expert discussion of experts and suggest that experts are not necessarily experts when it comes to evidence.

In episode 95, Mike and James look at the issue of non-specific low back pain and deal with concepts around diagnosis and we find out that x-rays aren’t that useful but MRI’s in the right patient population can play a role. We then start to look at the available evidence for treatment (massage, acupuncture, spinal manipulation) and at the end Mike tries to give James a two-handed neck massage and in retaliation James does acupuncture on Mike with a harpoon.

In episode 94, we get to yet more listener questions and provide vague, yet deep and thoughtful answers. We talk about the use of benzodiazepines, serotonin syndrome, buspirone, ‘urgent’ hypertension and pontificate even more on low doses. Mike and James realise that while low is often a good way to start, all their podcasts to date start of with high expectations yet end with not much more of an effect than placebo.

In episode 93, we once again get back to listener questions. We explore everything from haloperidol for nausea and vomiting, to statin dosing, ASA in diabetics, and finally Alzheimer's drugs. Towards the end, James and Mike realise that listener questions are too hard and they make up some easy ones of their own yet still struggle.

In episode 92, we do a final session with our two family physician friends and colleagues, Mike K and Tina K. We start off with Tina discussing some satisfying evidence for the use of bupropion in women with low sexual desire which causes sexually related personal distress. In the second part Mike K in a slightly less satisfying way looks at the recent evidence surrounding vascular surgery for a treatment of multiple sclerosis. To conclude this 3-part series we all stop talking, to the satisfaction of all our listeners.
