Episode 81: New studies about Vit K/INR, PUD, GABHS and statins

In episode 81, Mike and James talk about new studies. They run the gamut from Vitamin K, sequential therapy for peptic ulcer disease, single dose steroids for Strep throat and yet another meta-analysis of statin therapy. At the end we clearly demonstrate our skill at critical appraisal by recommending Vitamin K for ulcers, sequential antibiotic therapy for primary prevention, steroids for INR problems, statins for Strep throat (come on, you knew statins would work for this) and a kick in the ass for Chris our producer.

Episode 80: Listener comments and questions with an attempt at answers – Part II

In episode 80, Mike and James continue getting back to listener questions. We discuss such topics as glucose monitoring, ezetimibe, niacin, nebulised salbutamol and niacin with uncanny intuitive insight coupled with a degree of emotional sensitivity rarely encountered in podcasts. We then wake up and get Peter Loewen to help answer a difficult question on oral anticoagulants. Show notes 1) Self-monitoring of blood glucose ESMON BMJ 2008;336:1174-7 DiGEM BMJ 2008;336:1177-80 CADTH – thorough review of the  issue of glucose monitoring 2) Ezetimibe ENHANCE N Engl J Med 2008;358:1431-43 SEAS N Engl J Med 2008;359:1343-56 Cancer data N Engl J Med 2008;359:1357-66 3) Ezetimibe vs niacin – niacin better?

Episode 79: Listener comments and questions with an attempt at answers

In episode 79, Mike and James get back to trying to answer questions posed by our wonderful listeners. We both, in our own minds, give wonderful, thoughtful and sensitive answers to issues associated with diabetes, statins, metformin, strep throat etc. Unfortunately, our producer Chris edited all these out and you are left with a lot of ranting and raving from the duo. At the end of the podcast, James and Mike realise Chris has been editing all the podcasts this way and they go searching for a new producer.

Episode 78: The frail elderly – treat symptoms first, last and in the middle – Part III

In episode 78, the final one on the frail elderly, Mike and James, with John Sloan, deal with what is really important to the frail elderly, and that is symptom control. We discuss pain and opioids, sleep and benzos, and combativeness and whatever seems to work – but all in very low doses. To cap of this final episode on the frail elderly, Mike and James forget to plug John’s book and he experiences great pain, he can’t sleep and becomes quite combative, but fortunately Mike and James have listened to this podcast and know what to do.

Episode 77: The frail elderly – blood pressure is good – Part II

In episode 77, Mike and James stop waxing philosophically and get specific about therapeutics and the frail elderly. Once again we get our friend and colleague John Sloan to help us navigate through this evidence-free zone. We specifically talk about how to deal with the patient on 47 drugs and what to do about blood pressure, cholesterol, osteoporosis, and type 2 diabetes. To wrap it all up Mike, James and John do a no-analgesia drugectomy on each other and, other than a bit of whining, seem to do OK.
