Congratulations to my friend Dr Prem Alva!

2012-05-14T22:18:00.002+01:00

I would like to heartily congratulate my dear friend Dr Prem Alva (Consultant pediatric cardiologist) for his amazing work saving the life of a one day old baby girl with congenital pulmonary stenosis. Our common friends and I are extremely proud of him, and look forward to see him work wonders saving children like he does on a daily basis.

He made national news! Check out the article here.

We will be asking Dr Alva to write a brief article on congenital pulmonary stenosis for all our readers. Keep an eye out for it!!!

Well done Alva!

We are on twitter!

Support a charity - make a difference!

2012-05-14T18:15:00.000+01:00

Dear all

Charity has always been close to my heart, and today I have added a SocialVibe widget on the right hand side of this blog. You do not have to donate any money or even take out your wallet. All you need to do is click on the widget and the window that opens may ask you to rate a movie trailer or something along those lines. All it takes it a couple of minutes of your time, and it is for a good cause. The money is donated by big corporations like Apple or Colgate etc.

This month, I am supporting 'Children mending hearts'. Check them out on www.childrenmendinghearts.org. The widget states otherwise, but whatever it says, it still is for a noble and worthy cause.

I hope you all click on the widget and support the charities. If it asks you to return at a later date, please do so.

Thank you all for your time.

Warm wishes

Medical Mnemonics

2012-05-13T01:02:00.001+01:00

Oh, how we all loved mnemonics during medical school. Remember the carpal bones - 'She Looks Too Pretty, Try To Catch Her'?? Well, for the MRCP basic sciences section, what better way to remember the facts than with a book on mnemonics! Given that you are a seasoned medical student (or a junior doctor, as most of us call it!), get yourself a book with good mnemonics to remember all those bones, tissues, tendons, physiological pathways, biochemical pathways etc. We found one on Amazon that seems to be going strong. A quick preview and it looks good, packed with illustrations and interesting anecdotes. Here is the link for you:

For those of you who have a kindle, or have the software on your computer, you can download the book straight away -

The book combines mnemonics with humour, so it most certainly is a good read. Remember, a lot of questions in the MRCP part 1 exam cover topics from years ago. In addition to the books we have recommended in other posts, this appears to be a good accompaniment. Reviews by other users are great as well.

Enjoy it!

Book reviews

2012-05-12T22:54:00.000+01:00

Hey everyone

Over the next few weeks to months, I will be posting book reviews on various books that have been used by senior house officers and registrars for exams, and will also include reviews of books from medical school. They will be written by various experienced doctors, and will hopefully give you an insight into what to look for in the books, what is good, what is bad, what could make you fall asleep etc. We hope that these reviews help you make an informed decision on purchasing them if you wish. We will also provide you with links to purchase them as well - just to make life easy for you :-)

Until the next post....

Answer to clinical scenario - April 30th

2012-05-12T16:26:00.004+01:00

Hi readers

You may have seen this question recently :

A 60 year old Asian man with a history of type 2 diabetes on insulin and hypertension presents with deteriorating renal function and is referred by his GP to the renal clinic. In the renal clinic, he is found to have leg oedema, elevated JVP with rapid x-descent, ascites, mild jaundice and bi-basal dullness. Chest X-ray shows cardiomegaly. ECG shows left ventricular hypertrophy with strain. Resting heart rate was 100 bpm and BP of 90/70. The definitive cardiac diagnosis can be obtained by -

a. Cardiac MRI
b. CT pulmonary angiography
c. Ventilation-perfusion scan
d. Transthoracic Echocardiography
e. Right and left heart catheterisation

In the patient above, which of the following observation is likely to be true?

a. Absent contrast reflux into the hepatic vein on CTPA
b. Pulsus paradoxus of 30 mmHg on clinical examination
c. Paradoxical septal motion on transthoracic echocardiography
d. Myocardial speckling on CMR
e. Pulmonary capillary wedge pressure of 15mmHg on cardiac catheter

Here are the answers to the questions

Question 1 - d
Question 2 - b

Explanation

In the clinical scenario, the leg oedema, elevated JVP and ascites indicate high right ventricular pressures. Mild jaundice could be secondary to hepatic congestion and the bibasal dullness is likely due to pleural effusions. The rapid x-descent on JVP raises the suspicion of pericardial effusion, which is likely in this patient with renal failure. Hence option D is the investigation of choice.

Gadolinium contrast should be used with caution for cardiac MRI in the presence of significant renal impairment, so is not indicated in this patient. The clinical history makes acute pulmonary embolism unlikely, and hence CTPA and V/Q scan are not indicated. Right and left heart catheterisation is indicated in the absence of pericardial effusion, and aid in the diagnosis of restrictive cardiomyopathy of constrictive pericarditis.

Reflux of contrast into the hepatic vein on CTPA is indicative of tricusid regurgitation and high RV pressure. A pulsus paradoxus of 30 mmHg indicates cardiac tamponade which is likely in this patient with hypotension, tachycardia and clinical features of severe pericardial effusion. Paradoxical septal motion on transthoracic echo is indicative of pulmonary hypertension (which could be secondary to other causes). Myocardial speckling on CMR is seen in amyloidosis.

A PCWP of 15mmHg on cardiac catheter indicates minimally elevated left atrial pressure, which is unlikely to be the case in this patient. Therefore the answer to the second question is B.

Note : In patients with pulmonary hypertension and cardiac tamponade, the classic echo features of right atrial and right ventricular collapse may be delayed.

Our sincere thanks to Dr Ramachandra, senior registrar in interventional cardiology for his input.

New questions coming soon!!!

A question from our website

2012-05-09T08:59:00.000+01:00

Q. The normal resting membrane potential of ventricular myocardium is

a. 85 to 90 mV
b. -85 to -90 mV
c. 70 to 80 mV
d. -70 to -80 mV
e. -30 to -40 mV

A. b. -85 to -90 mV

The resting membrane potential is corresponds to stage 4 of cardiac myocyte contraction. It is primarily due K+ channels. The resting membrane potential corresponds to diastole in cardiac contraction, and the normal potential is between -85 to -90 mV. When the myocyte is stimulated during the resting membrane potential, it results in influx of Na+ ions and the start of contraction.

As is seen in the above image, the cardiac action potential consists of 5 stage, beginning with phase 4 all the way back to phase 4.

Phase 4 - corresponds to resting membrane potential. K+ channels are open, and an electrolyte balance is achieved to maintain the potential between -85 to -95 mV

Phase 0 - This corresponds to the start of the action potential, and is due to rapid influx of Na+ ions and a rise in membrane potential. In essence, this is the depolarisation phase.

Phase 1 - The Na+ channels close, and the membrane potential reaches a plateau.

Phase 2 - The L-type Ca2+ channels open and calcium influx occurs. Outward movement of K+ starts in this phase.

Phase 3 - The Ca2+ channels close, and K+ efflux continues. This is the relaxation / repolarisation phase of the myocyte action potential.

Rivoroxaban

2012-05-06T23:17:00.003+01:00

Good knowledge of drug pharmacology forms the basis of good clinical practice. While discussing each and every drug there is out there is out of the scope of this blog, today we shall talk briefly about Rivoroxaban.

Rivoroxaban

Direct anti-Xa inhibitor
Administered orally and has good bioavailability
Unlike warfarin, it does NOT require regular monitoring, and the dose remains the same to achieve adequate anti-coagulation
It is currently approved for use in Atrial fibrillation (ROCKET-AF)
It is also useful in prevention of venous thromboembolism

From an MRCP point of view, clinical pharmacology forms a reasonable proportion of the exam. Make sure you get a good book with questions, rather than read a textbook. There are not many out there, here are a few:

There are more books available, but they all remain rather ancient, with no recent editions in the last 5 years. The books listed about are cheap and affordable. Definitely spend a lot of time with clinical pharmacology. It is as important as basic sciences (see our basic sciences post), so find a study partner, and study hard! Its well worth studying pharmacology this way rather than reading a huge textbook with a lot of unnecessary information - well, from an exam point of view.

All the best! Next exam 11th September (kind of a jinxed date, isn't it!)

PACES review on your computer??

2012-05-03T15:21:00.000+01:00

While scouring for good information and books on Amazon, I came across a Kindle version of the PACES book we featured in this blog. Well, it more of 'an aid' to the existing books, but sometimes that's just what you need for last minute revision. Did you know you can access Kindle books on your computer, though its great own a Kindle and revise on the go! Here it is my friends -

Carrying heavy books around can be frustrating. This book on your Kindle or on your computer is brilliant to revise when travelling about. I am assuming that you all possess a Kindle - if you don't have it, get one! Its great - why do you think it remains the number one seller on Amazon!! :-)

Best wishes y'all!

Book review - MRCP part 1 Basic sciences

2012-05-01T19:34:00.001+01:00

OK, for those of you preparing for the part 1 exam, here is a valuable tip. Basic sciences - spend a lot of time with that. Not just a few days, not a weekend, but at least a good fortnight of solid reading. I say this as it carries the highest number of marks in the part 1 exam, and believe me when I tell you can score full in that section as its all about remembering facts.

Now, you can go out there, dig out all your old books from medical school days and start from page one. What we suggest is to read 'Basic sciences for the MRCP part 1' by Phillipa Easterbrook. This book is brilliant. It covers all the basic science that is relevant to the exam, starting from anatomy to biochemistry and physiology. Also covered is immunology, a subject that a lot of medical students find extremely hard to understand and remember. Of course, bear in mind this is not a textbook, it's more of a 'fact book'. It's brief, concise and precise. It's an easy read too, but we would recommend group study when it comes to basic science as its a good idea to quiz each other when preparing for the exam. You will find it to be to the point, covering just those topics that are important from an exam point of view. Easterbrook also has a 'Best of five' book as well, which is a valuable accompaniment to the original book.

Everyone uses it, so we recommend you get yourself a copy from the bookstore or online. We have included the links on Amazon where you can buy it from - ensure you have the latest edition and not a hand me down from a senior who did the exam donkeys years ago! Score full in basic sciences, and it is highly likely you will pass the exam. A lot of us ignored this advice from our seniors, and have failed the exam miserably, or just by that one dreaded mark! So go get this book! - if you don't believe us, go check out the user reviews on Amazon, they speaks for themselves!

We hope you enjoy these books - we are confident you will find them useful.

Happy reading!

Answer to clinical scenario 27.03.2012

2012-04-30T19:40:00.001+01:00

Hey everyone,

You may remember the clinical scenario that was posted on the 27th of last month. Well, for those of you who were wondering what the actor was asked to do - if the candidate apologised for the accident with the lignocaine and stated that it was contraindicated in her father, the actor would stand up and shout 'you killed my father' and leave the room! Imagine that.

The correct way to handle that situation is to explain the situation in its totality, and explain that at the local anaesthetic concentration, lignocaine pretty much has no effect on the heart, so would play no role in contributing toward the patient's death. Of course, you would also get a senior to discuss the situation with you and the family together.

MRCP clinical scenarios only appear scary on paper. They are no more than regular scenarios encountered in clinical practice. Keep a cool head, and they are all a walk in the park.

More scenarios soon!

Book Review - Anatomy!

2012-04-30T19:32:00.001+01:00

Hello readers, hope all of you are well. Sorry it has been a while since my last post, but not only have I been travelling a bit but have been attending numerous meetings - been hectic! Its good to be back and see that the blog has had over 1000 views so far!! Thank you to all who have visited the blog.

Later today, I will be posting a clinical scenario for you all to discuss - something that is relevant to the MRCP exam. But for now, I will be quickly reviewing a book that got me (and many others) started in medical college. I do this as it brings back great memories - one of excitement of starting medical school, confusion as to what the difference between a tendon and aponeurosis is, and of course the beginning of a long career of healing.

So yes, the book I am referring to in the title is not Greys anatomy, but what we considered to be our Greys anatomy text book - 'Human anatomy' by BD Chaurasia. Best thing about the book - the simple, reproducible diagrams. Of course, anatomy is tedious and difficult, and memorising what nerve goes through what canal under what bone and over what muscle is hard, but the simple figure in this textbook just make memorising such facts easy. And as a first year medical student at the tender age of 16, I don't think I could have handled a huge textbook with complicated 3D figures - don't you agree?!!

I submit this post is probably not relevant to my readers as most of you are way past medical school and probably practising in you area of expertise, but a trip down memory lane never hurt anyone! Feels kinda nice :-)

Well, I am sure that myself and my 300 classmates, and everyone from most universities who have used this book would recommend it - we pretty much considered it the 'bible' of human anatomy. You can purchase your copy from Amazon, and I have attached a link below that should avoid the hassle of searching for the book and take you directly to the page -

It is definitely worth it, especially if you are preparing for entrance exams - the diagrams (though may appear redundant) are packed with information and are great to memorise facts. A lot of them I still remember, 12 years post graduation!

Clinical scenario coming up next!

Ticagrelor

2012-04-01T17:53:00.003+01:00

Those of you who are keeping up to date will have no doubt heard about Ticagrelor, a new antiplatelet drug. Below are key points regarding this revolutionary drug

Mechanism of action - Reversible platelet ADP receptor blocker (P2Y12)

Unlike Clopidogrel, it is not a thienopyridine drug.

Advantages over Clopidogrel include a more rapid onset of action and its platelet inhibition is more pronounced. Bleeding risks are not different from Clopidogrel either.

From the MRCP point of view

1. Its a reversible P2Y12 inhibitor
2. More rapid onset of action compared with clopidogrel
3. More potent platelet inhibition.

There are recent studies looking at the role of Ticagrelor in ACS. The NEJM published the PLATO study that compared Ticagrelor and Clopidogrel in patients with ACS. The primary end points were significantly reduced. Interestingly, dyspnoea was a side effect seen more often with Ticagrelor.

It is a good idea to know what this study involved. Read the study here.

Pharmacology is a big part of the MRCP part 1 exam. Read a good book and thou shalt pass! Here are a few

Case 1 - How will you handle this?

2012-03-27T11:55:00.002+01:00

You are called to casualty to see an 81 year old man who has a background history of ischemic heart disease and hypertension. He is admitted with acute shortness of breath and is in atrial fibrillation with a ventricular rate of 162 bpm. His blood pressure is only 80/60 mmHg. He is in heart failure. He is being given oxygen, but the staff are having a lot of difficulty obtaining peripheral access. You insert a central line in, flush it to ensure it's patency, and give him some frusemide to help shift the fluid. Unfortunately a short while later, he arrests, and despite the best resuscitation efforts, he dies. While cleaning up the area, the staff mentions to you that the patient's daughter is in the waiting area and has no idea what is going on. While preparing yourself to go and speak to her, you notice that you injected lignocaine (used to anaesthetise the skin) into central line while flushing it instead of saline. Knowing fully what the effects of intravenous lignocaine can be in such a situation, you have to now speak to the daughter, who is anxious to know what is going on, as she is his main carer.

How will you go about handling this scenario? Submit your answers in the comments box and I will tell you what the daughter was instructed to do!

By the way, this was an actual scenario that I wrote for the exams. Good luck!

Passing the PACES

2012-03-27T11:26:00.000+01:00

Right, once you have passed the written exam, then comes the toughest part of the MRCP - (drumroll!) the PACES. 5 stations, tough clinical cases and some moody examiners! But go in with the right preparation, and you will absolutely wing it! Its really not that hard; just think of it as a ward round or an on-call shift where you are asked to see complicated and sick patients. Beware however, sometimes you could get a normal case, like I did in my exam 6 years ago. I remember it well - abdominal station, normal abdomen but she was pseudocushingoid. Don't know how, but I got it! Phew!

Well, actually I do know how. Like many of us who passed, we had the right tutors and the right books to prepare. While you may get some old books handed down by registrars to you, just remember that newer editions and new books that emerge have new cases and sometimes provide you with valuable tips on picking up ceratin things. Of course, the whole inspection-palpation-percussion-auscultation rule always applies, but its the little things that these books will help you with.

I have listed a few books below that will no doubt be useful. Once you have these, ensure you have a study partner who will critique you every time you examine a patient. I tell you, it helps.

I have organised the MRCP PACES exam in the past, and I have seen first hand what the examiners can mark you down on, and what you can score full on. Remember the steps in examination and be cool and calm. No patient wants to see a nervous doctor!!

Books to read :

I would strongly recommend these. Study well and you can score full marks. In my next post, I will be placing a tough clinical scenario that was in the MRCP communication station a few years ago. I look forward to hearing how you will handle it!

Happy reading!

Mnemonic #1

2012-03-25T22:32:00.002+01:00

Mnemonics are invaluable in remembering features and facts about different conditions in Cardiology. From time to time, I will post some mnemonics I have found on the internet on this blog. I hope you find them useful. I will try and keep them 'clean', but you all know that mnemonics that we all tend to remember are the 'inappropriate' ones :-) ! We kick off this thread with

Causes of Atrial Fibrillation (ARITHMATIC)

Alcohol
Rheumatic fever
Idiopathic
Thyrotoxicosis
Hypertension
Mitral stenosis / Myxoma
Atrial septal defect
Toxins
Ischemic heart disease
Cardiomyopathy (commonly dilated)
