Episode 139: PREMIUM – Irritating information about IBS and Cold-FX

In episode 139, James and Mike and Tina Korowynk talk about the available evidence for therapies for irritable bowel syndrome and our good friend and colleague Mike Kolber drops in for a few minutes at the end “runs through” the reality of the situation. We then talk about the recent publication of the largest trial of Cold-FX and find that what wasn’t shown to be statistically different is at least if not more important than what was shown to be statistically different.

Episode 138: Seeing right through the evidence for the risk of CT scans

In episode 138, MIke and James celebrate their triumphant return from New Zealand by inviting Tina Korownyk to help explain the risks associated with CT scans and other forms of radiation. In addition, we ask her to help Mike with his fear of airport scanners and find out that just because a full body search feels good that doesn’t make it right.

Episode 137: Putting the patient back into the diabetes guidelines – the VA perspective


In episode 137, James and Mike welcome Mark McConnell back to podcast land to discuss the latest change in diabetes management guidelines. Mark leads us through a great discussion about how the VA has decided to do a bit of an about face, and incorporate not only evidence but also patient values and preferences into their most recent glucose control guidelines. At the end we all agree that an A1C measurement, no matter if it is 7, 8, or 9, is just a number and is not the ultimate endpoint for proper diabetes care.

Episode 136: PREMIUM – A head-to-head comparison of ezetimibe and prunes

In episode 136, James and Mike once again raise the content bar level with the premium of all PREMIUM podcasts. We talk about a study that looked at the effect of ezetimibe plus simvastatin and we get a very clear answer but unfortunately the question that was asked was completely wrong. We then bring the podcast to a rising never ending crescendo by discussing a “pivotal” trial comparing psyllium to prunes in chronic constipation and low and behold the answer is extremely useful and relevant to day-to-day practice.

Episode 135: Antipsychotics – use in the elderly – part 4

In episode 135, Mike and James and Adil finally get to the end of their antipsychotic tetralogy as they tackle the especially difficult issue of the use of antipsychotics in the elderly. The problem is non-pharmacological treatments do very little, and one is left with having to decide whether or not to use drugs. We discuss the evidence of effectiveness (or lack thereof) of these drugs and the very real potential for harm. At the end, Adil makes both Mike and James agitated and he sedates them with a high dose of a very fine cognac.

Episode 134: Antipsychotics – schizophrenia the drugs – part 3

In episode 134, we get into the nitty gritty of choosing a second drug for schizophrenia if the first one doesn’t work or is not tolerated. In general, it appears there is some evidence to favour clozapine over other agents but the difference isn’t great and as with virtually all of medicine one has to intermingle the available evidence with a good dose of art to make a beautiful therapeutic picture.

Episode 133: Antipsychotics – schizophrenia the drugs – part 2

In episode 133, Mike and James again welcome Adil Virani to help us along with our antipsychotic drug discussion. We discuss the differences between the first and second generation antipsychotics, how to start, and when to consider a depot preparation. At the end of the podcast James realises that he has basically been hearing voices for the entire podcast but was reassured to find out the voices were actually Mike and Adil’s and that in general, they were telling the truth.

Episode 132: Antipsychotics – schizophrenia the condition – part 1

In episode 132, Mike and James bring back their good friend and psych colleague Adil Virani, to help out in thinking about the use of antipsychotics. In part 1, we talk about schizophrenia in general and start to get into a discussion of the use of antipsychotics for this condition and how to decide what drugs to choose. However, at the end our thought process becomes a bit scattered and we decide to leave the discussion about the specific drugs to the next podcast.

Episode 131: Multimorbidity: a challenge for EBM and Mike and James

In episode 131, Mike and James have invited Denise Campbell-Scherer into the podcast world to help us discuss the issue of multimorbidity when it comes to guidelines and chronic medical conditions. We talk about how to think about this issue when it comes to research and practice and we very quickly realise it is tricky and it demands that clinicians need to realise that guidelines are system-based and not patient specific focussed. At the end we decide that we need to take care of patients and not disease states.

Episode 130: Getting exorcised about the evidence around exercise

In episode 130, Mike and James run directly into the face of the evidence around exercise and really sweat out the weightiness of the results. We actively find out that it’s primarily all about quality of life, and that Mike bikes and James rollerblades to keep themselves as close to perfect physical specimens as possible. At the end we find out they also both take medications for delusions of grandeur.
