Re: SCE Endocrinology and Diabetes practice question from OnExamination: What are the side effects of exenatide?

The correct answer is: Risk of pancreatitis

Explanation:

Acute pancreatitis has been reported in 89 patients treated with exenatide up to September 2007.

The majority of cases (87 out of 89) have occurred in the USA.

Many of the patients who developed pancreatitis had co-existent risk factors for the development of pancreatitis such as alcohol excess, gallstones or hypertriglyceridaemia.

However, despite this, the Food & Drug Administration (FDA) indicated that they felt there was an association between exenatide and the development of pancreatitis in some cases.

Consequently, the FDA advised that patients commencing exenatide should be advised to 'seek medical care promptly if they have unexplained persistent severe abdominal pain, which may be accompanied by vomiting'.

Other recognised side effects of exenatide include gastrointestinal disturbance such as:

  • nausea
  • vomiting
  • diarrhoea, and
  • bloating.

Headache, dizziness and injection site reactions are also recognised side effects.

Weight loss is a benefit of treatment not a side effect.

Hypoglycaemia occurs rarely in patients treated with exenatide in addition to metformin (incidence of 4.5-5.3% compared with 5.3% in placebo treated patients).

If exenatide is used in combination with a sulphonylurea, or both metformin and a sulphonylurea, then the incidence of hypoglycaemia is much higher (14-36% compared with 3% in the placebo group).

In Response to Re: Diminished Capacity and Criminal Law:[QUOTE]

Kirked

This must make most clinicians (and lawyers) uncomfortable.  It presumably comes within the concept of capacity legally.  The default position in clinical practice is to assume that capacity exists until it can be shown that it is impaired.  The general tests for capacity here would presumably have to to show that the criteria applied specifically to his ablility to instruct counsel and to follow proceedings.  Surely, it is for a judge to appoint psychiatric assessors to make these judgements and, as you say, for the process to be transparent.  We are not told who made the judgements and it what circumstances.

I can't see how the claim that he is 'no threat to the public' is connected to the judgement about dementia but there may have been some other reason for that.  I would regard any future involvement in The Lords or other aspect of law-making as a distinct threat to the public.  I couldn't possibly say if some active politicians don't fall into the same category.

Lord Janner has to be considered innocent until proved guilty but dementia of the severity that precludes trial is essentially irreverrsible and if, like Saunders, Lord Janner later makes a miraculous recovery, a charge of perverting the cause of justice might be added.

I had in the back of my mind something about another type of judicical process by which a judge could somehow review the evidence in the absence from court of the defendant.  Is that the case or have I also begun to lose it?

Many thanks Maxim,

The threat to the public aspect of the DPP decision refers to the matter that if no prosecution goes ahead would the accused be likely to commit further offences of the type alleged? In this case the answer is no, because the dementia is such that he would not be in any position to abuse. On that specific point I am in agreement. Janner must of course be considered innocent unless and until he is found guilty - but it is clear to see that the DPP was satisfied that the evidential burden had been met (when assessed at three different times in the preceding thirty years) but factors such as mismanagement, incompetence or cover up prevented a trial taking place when it should have done. Over the last decade there have been cases where elderly men with Dementia have been prosecuted and imprisoned for the same type of offences - it is not surprising that people think 'the establishment' are covering up in this case.

Newspapers have stated that Janner was signing legal documents regarding his financial affairs and was in correspondence with the House of Lords up until over a matter of weeks before the DPP published her decision - he cannot have Dementia so bad he cannot be tried but perfectly capable of managing his own financial affairs. As you rightly say, if he suddenly makes a remarkable recovery there would certainly be some very serious legal questions asked.

As regards the medical experts, two were appointed by the cPS and two by the defence. I don't doubt that the Doctors formed their opinions in good faith but people are rightly skeptical post Saunders, Pinochet et al.

One possibility that the DPP did not put forward - and I believe she should have - would be a trial of facts. While Janner would not be standing trial and could not be found guilty or not guilty, a Judge could hear in open court the allegations and charges, hear the evidence and make a finding on whether the crimes alleged had taken place. At least that way the alleged victims would have an opportunity to state their case and a historical record would be determined. In my view the DPP should have done this, and could still do this. There is concern that victims will be less willing to come forward when famous or well placed people are accused of sexual abuse - a trial of facts would surely be preferable.

Overall, this case has been managed very badly for thirty years. Police officers say they were told by the powers that be not to pursue an MP (likewise with Cyril Smith), alleged victims not treated with decency, the CPS not vigorously managing their case and finally seeming to give Janner a get out of jail free card. Perhaps the full public inquiry which has been started will get to the truth.

Do you think this advertisement is unethical?

We take the Daily Telegraph in our house (Know your enemy, I say) and like others it has a Saturday Colour supplement.  This full page ad appeared this last weekend.

 

As you can see, it's for a Hilton Hotels "Weekender" short holiday package, and invites you "Get, set, go! Make a fast getaway"     On a scooter, dressed for the beach, without helmets.

There have been so many holiday makers maimed or killed, hiring scooters on holiday and, inexperienced or drunk, falling off.    I thought that a responsible newspaper like the Telegraph would have let this one by only in a moment of inattaention.   But no!

"this was an independent advertisement designed, paid for and placed by the company concerned ... you will appreciate that we are presented with thousands of advertisements in the course of a year and it simply isnt possible to check ... We do our best to ensure they appear to be legal, decent, honest and truthful.", said the Telegraph's Enquiries Desk.   In other words, we were only obeying orders.

Who else might see the error of Hilton's ways?  Ah, the Advertising Standards Authority.  Which thanked me for my complaint and will get back to me within ten working days.   Dammit!  That foolish young man and his girl could be dead and buried in ten days!

Complain to Hilton Hotels, you say?   Gladly, if you will give me a contact that isn't "Reservations/ Meetings & Groups/ Investor Relations/ Hotel Questions/ Travel Agent/ etc.etc."

Do you think I'm an interfering old fool?    I think that a hotel company that encourages reckless and, in this country, illegal use of a motor bicycle, should be shown the error of their ways.

Over 75 and DNR

One of our newspapers (not one I would buy) has a main feature on the front page about an apparently new policy to ask those >75 about their views on DNAR. Provided this is introduced as a topic and not a decision to be made irrespective of the illness , I cannot see a great objection , apart from the obvious one that reminding anyone that they might die is seen as totally outlandish. Of course it would be wrong to try to obtain a clear decision unless clinically indicated but as a discussion point there is much to be said for it and after 75 there is an increased risk of acute hospital admission in a state where it could well be difficult to engage in constructive discussion.

Inevitably the response has been pretty over-the-top. The woman at the counter had also seen the headline and said she remembered a book where the elderly were killed off to provide food for the hungry and this seemed to be the first step in that direction..... 

DOI  >75

PS Just had 2 weeks windsurfing in Tobago + fair amount of reading. "I'll see myself out , thank you" is a good short read. A collection of essays (Warnock , Will Self and others) giving some views on end-of-life with quite an emphasis on what the elderly think - or at least the thinking elderly.

I agree with John D that it's important for the profession to keep these things clinical.  The jokey tabloid names for lethal drugs can distort the real nature of such drugs and we should counter these fashions whenever possible.

Even 'ordinary' compounds used for genuine clinical reasons can cause  devastating tissue necrosis when extravasated.  8.4% sodium bicarbonate and 50% dextrose are two of the worst offenders and we still see these problems even with apparently good iv access.  pH and osmolarity are probably the mechanisms in the absence of infection.

Addicts will always find ways to do themselves serious damage but we also need to remind inexperienced staff of similar dangers in their own practice and that the use of these concentrated preparations is rarely, if ever, necessary.

Really, Poltor, do tell!   References, proper trials, please.

On the other hand,  Mathie and Clausen's meta-analysis, in the January issue of Homeopathy http://www.ncbi.nlm.nih.gov/pubmed/25576265 could only find, " some very limited evidence that clinical intervention in animals using homeopathic medicines is distinguishable from corresponding intervention using placebos"

If that is the best that a Homeopathic journal can find, then the whole "discipline" should be discarded.

Surely a Doctor as intelligent as you must have had reason to travel the  cerebral voyage through Kant's Critique of Pure Reason?   I read Kant for relaxation after a day of calculating downwind hazards associated with chemical or nuclear hazards.     In any event,  I hope the NHS does not cover Homeopathy.    I believe it to be Quackery!

A rather pathetic orthopaedic surgeon.  What doctor every sees everything in their specialty, when orthopaedics is so large and medicine changes with time?   I've certainly not seen everything in anaesthesia in thirty-plus years, but I hope I've read about almost everything!

And I hope that Mr.Bicknell is being Devil's Advocate, saying that surgery is such a craft that its practitioners need not know about the science of their specialty.    Surely he will agree that progress in modern surgery has to be based on the evidence of properly conducted trials, and that a fully trained (if not experienced, see above) surgeon should have as part of their professional background a knowledge and experience of trials.

Why will these so-called intelligent people not realise that two factors head the list of damage to the NHS - 1) the Internal Market and the management tiers which it generated, and 2) the stupid idea of 'Efficiency Savings' AKA cuts across the board.

Stopping both of these would allow the NHS to work better at no extra cost!

In one sense extreme bodybuilders may indeed be 'not like us'.  I've seen a claim that a significant proportion of the top competitors have a mutation in a gene coding for functional myostatin, the protein that normally stops skeletal muscle growing beyond a certain size.  It's a similar mutation to the one responsible for the dramatic musculature of Belgian Blue, 'double-muscled', bulls.  My attention was drawn to this when the local farmer put an incredible looking (luckily placid) bull in the field next to our house.  The farmer denied emphatically that he'd been giving the animal anabolic steroids!

maxim makes an important point. What I found interesting in this thread is that the evidence is so poor. It should be feasible to do a good study on paracetamol levels in those on regular prescribed paracetamol and look for evidence of outside sources. The problem would be that obtaining informed consent would re-emphasise the need not to take these and so the study could be self-defeating. The guidelines for those considered as "at risk" seem somewhat arbitrary with the dose : kg bodyweight etc... being in the equation.

A similar problem exists with NSAID - I take my long acting prescribed one cautiously and do not double up with my OTC ibuprofen , but there are times when I am tempted.

I doubt whether the test patient in this thread would have been in a major danger zone but at least she would (hopefully) have been wiser if referred to the A&E as an emergency. Presumably the episode would also have been reported as a "significant clinical incident" : how does this system work in general practice?

As a patient with this condtion I do wonder about the wisdom of antibiotic use to treat. So far i have refused them and the condition seems to self limit -although pain ofen persists for a week or two ect. natural yogurt, honey and extra sleep seems to sort it out at the moment. My GP has never referred me for investigation although my sister who lives in a different country has had a scan. She also has accepted some 'bulking agents' but i have decided that it is eventually about stress levels  and life style.

Traumatic Brain Injury (TBI) is a feature of fast life style worldwide but the numbers of patients are more in countries with huge population like India, Pakistan, and Bangladesh. The statistic shows that they are usually young people and otherwise with robust heath. The researchers have a good chance to re-evaluate the efficacy of a relatively inexpensive drug call Amantadine freely available, in the TBI patients in India, Pakistan and Bangladesh.

Just to point out - many doctors have - mostly unwillingly - become civil servants.

Among the many restrictions this places on their ability to advocate for the populations they serve, this means that if they wish to stand as an MP they must first resign from their posts (though they may be entitled to get their job back again if they're not elected).

Any civil servant doctor would have to take this into consideration.
