Cade, John Frederick Joseph (1912 - 1980)
Taking lithium himself with no ill effect, John Cade then used it to treat ten patients with chronic or recurrent mania, on whom he found it to have a pronounced calming effect. Cade's remarkably successful results were detailed in his paper, 'Lithium salts in the treatment of psychotic excitement', published in the Medical Journal of Australia (1949). He subsequently found that lithium was also of some value in assisting depressives. His discovery of the efficacy of a cheap, naturally occurring and widely available element in dealing with manic-depressive disorders provided an alternative to the existing therapies of shock treatment or prolonged hospitalization.

In 1985 the American National Institute of Mental Health estimated that Cade's discovery of the efficacy of lithium in the treatment of manic depression had saved the world at least $US 17.5 billion in medical costs.

And many lives too!

I have just received a query from a reader of this blog about Lithium, and I thought it worth me reiterating my views here.      It is no secret that I am a traditionalist who believes that lithium is the drug of choice for Bipolar disorders.

The following is an extract from The Cockroach Catcher:
“Get him to the hospital. Whatever it is he is not ours, not this time. But wait. Has he overdosed on the Lithium?”

“No. my wife is very careful and she puts it out every morning, and the rest is in her bag.”

Phew, at least I warned them of the danger. It gave me perpetual nightmare to put so many of my Bipolars on Lithium but from my experience it was otherwise the best.

“Get him admitted and I shall talk to the doctor there.”

He was in fact delirious by the time they got him into hospital and he was admitted to the local Neurological hospital. He was unconscious for at least ten days but no, his lithium level was within therapeutic range.

He had one of the worst encephalitis     they had seen in recent times and they were surprised he survived.

Then I asked the Neurologist who was new, as my good friend had retired by then, if the lithium had in fact protected him. He said he was glad I asked as he was just reading some article on the neuroprotectiveness of lithium.

Well, you never know. One does get lucky sometimes. What lithium might do to Masud in the years to come would be another matter.

I found that people from the Indian subcontinent were very loyal once they realised they had a good doctor – loyalty taking the form of doing exactly what you told them, like keeping medicine safe; and also insisting that they saw only you, not one of your juniors even if they were from their own country. It must have been hard when I retired.

Some parents question the wisdom of using a toxic drug for a condition where suicide risk is high. My answer can only be that lithium seems inherently able to reduce that desire to kill oneself, more than the other mood stabilizers, as the latest Harvard research shows.

Lithium has its problems – toxic at a high level and useless at a low one, although the last point is debatable as younger people seem to do well at below the lower limit of therapeutic range.

Many doctors no longer have the experience of its use and may lose heart as the patient slowly builds up the level of lithium at the cellular level. The blood level is a safeguard against toxicity and anyone starting on lithium will have to wait at least three to four weeks for its effect to kick in. In fact the effect does not kick in, but just fades in if you get the drift.

Long term problems are mainly those of the thyroid and thyroid functions must be monitored closely more so if there is a family history of thyroid problems. Kidney dysfunction seldom occurs with the Child Psychiatrist’s age group but is a well known long term risk.

Also if there is any condition that causes electrolyte upset, such as diarrhea, vomiting and severe dehydration, the doctor must be alerted to the fact that the patient is on Lithium.

Could Lithium be the Aspirin of Psychiatry? Only time will tell!

Junior Doctors & Sunset: 1st day & Tears?


No, it was not the sunset that brought tears:


From Avatar Land© 2015 Am Ang Zhang

This is extracted from another post that is about not just the strange medical condition that I have to wait 30 plus years for an answer but to the Junior Doctor that I fondly remembered. This brought tears to my eyes as it was NHS at its best.


Now are we seeing the end game that Jeremy Hunt is playing. Well, only 54,000 pawns left on the Chess Board.

.........Perhaps we should catheterise her. She had not been seen to use the toilet for hours although she was not drinking much. She was still going round in her room – we gave her the side room and a nurse – and we put on an input output chart so we knew. The new junior doctor’s car broke down so she was late in examining her.
         Bother, I forgot it was changeover time, when new doctors came in for their new six-month rotation.  This is one of the days of the year not to be ill.
         “Good work Sister. What do we do without you?”
         Sister did the catheterisation but only got about 150ml. The mass was still there.
         I phoned Ob-Gyn. The consultant had left for home, but I got her Senior Registrar.
         He came over. Yes, it was possible that she was pregnant but unlikely as there were no breast changes. He would hate to do an X-ray but that seemed justified in the case of an undiagnosed abdominal mass.
         My mind was racing now. Sometimes you do have to believe what you see. Sometimes you have to believe the parents. She was not one of those girls. She could not be pregnant. So now we had to go through the differential diagnosis for abdominal mass in a young girl of thirteen.
         Ovarian cyst was the obvious one.
         This big?
         Possible.
         No. It cannot be.
         The x-ray came back. The tell tale tooth was there and yes – a Teratoma, the distinctive type of tumour that can include teeth, hair, sometimes, even a jaw and tongue.  I guessed just a split second before the results came back. How annoying.
         Working diagnosis: Teratoma with possible toxic psychosis.
         Emergency operation was arranged. Yes, she would be fine a little while after the operation, I reassured the parents.
Junior Doctor arrived:
         The junior arrived and took some history and did a quick physical before she was prepared for the theatre. This petite doctor with a very babyish face told me that on her first day in her last job she had to do an emergency tracheotomy. This time she had been on call for the last three nights and the battery in her old Mini could not cope with the heavy frost so she had to wait for AA before coming. She was most apologetic for not having got in earlier. 

She asked if I had seen many toxic psychosis cases and I asked if she had come across any in her psychiatric placement. As with all good psychiatrists answering a question with another is in our blood and here it worked well.
         Neither of us knew what was to hit us next.


At 2 A.M. I had a call from her.
        “Your patient – I mean our patient could not be aroused after the operation. Yes they removed the teratoma, complete and intact. It is bigger than any specimen I have seen but she could not be aroused.  Any ideas?”
        “Call the paediatrician on call in the regional paediatric unit and I will be in.”
        What happened?  I asked myself as I drove to the hospital.
        What had we done? This was fast becoming a nightmare situation.
        What was I going to say to the parents?
        Something else was going on here, and I was not happy because I did not know what it was. I was supposed to know and I generally did. After all I was the consultant now.
        Thank goodness she could breathe without assistance. That was the first thing I noticed. I saw mother in the corner obviously in tears. She asked if her daughter would be all right. I cannot remember what I said but knowing myself I could not have said anything too discouraging. But then I knew I was in tricky territory and it was unlikely to be the territory of a child psychiatrist.
        A good doctor is one who is not afraid to ask for help but he must also know where to ask.
        “Get me Great Ormond Street.”
        “I already did.”
        She is going to be a good doctor.
        “Well, the Regional unit said that they had no beds so I thought I should ring up my classmate at GOS and she talked to her SR who said “send her in”.”
        Who needs consultants when juniors have that kind of network?  This girl will do well.
        “Everything has been set up. The ambulance will be here in about half an hour and if it is all right I would like to go with her.”
        “Yes, you do and thanks a lot.”

        I told mother that we were transferring her daughter to the best children’s hospital in England if not in the world and the doctor would stay with her in the ambulance. She would be fine.


.........She was impressed with mother’s faith and trust in God.
        She said mother was near to tears. It was bad enough to have such a large Teratoma and then to have the patient unconscious with no one knowing what was going on was very frightening.
        “I have seen some deaths as a medical student but never since I was registered. I do not want this to be my first.”
        I knew the feeling well but what could I say? A doctor has to face it some time.
        “Do you believe there is God?” She asked
        “Do you really think I can answer that one?”
        “Well, you have more experience.”
        “To me it is like reading a good book. You would not know until the end.”
        “So you mean I am not going to know until then.”
        “Interpret whichever way you like. I remember Jung in his Memoir gave quite an account on the Holy Trinity.  There were seventeen bishops in Jung’s family including his own father. Jung had always been puzzled by deity and the bible and most of all by the concept of the Holy Trinity. I know many religious philosophers struggle with that too. By some accident he had access to his father’s inner library. He saw this folder clearly marked Holy Trinity. The relief was phenomenal. He could now have the answer. He hesitated before opening the folder.”
        “What did the folder contain?”
        “See, you want the last chapter. I wanted to know as well. The folder contained pieces of blank paper.”
        “That was it?”

        “That was it.”

  A  reprint:

NHS & Ham: World Class Medicine without trying!

Those doctors that grew up here may not know but those of us from overseas looked forward to coming for our specialist training in this country. A number of us went to the US and they did well too. There was little doubt that for many the years of training in the top hospitals here will guarantee them nice top jobs in Hong Kong or the rest of the commonwealth. 

Why?

We provided World Class Medicine without trying. A quote from a fellow blogger, Dr. No.


Dr No said...
Excellent post - and yes, that is exactly how it used to be. World class medicine without even trying - we just did it, because that is what we did, just as the dolphin swims, and the eagle soars. A key, even vital feature was that the doctors looking after their patients did not need to worry about money or managers. They just got on with it. There was no market to get in the way of truly integrated care. Some may point out that 13 year olds with teratomas are rare, and that is true, but what this case shows us, precisely because of its complexity, is just how capable the system was. And most of the time (of course not always), it dealt just as capably with more routine cases. "How is (sic) the new Consortia going to work out the funding and how are the three Foundation Trust Hospitals going to work out the costs." Exactly. And then: who is going to pay for the staff and their time to work out out all those costs and conduct the transactions?
What many politicians may not know is that pride in what we do is often more important than money or anything else. Our pride is one sure way to ensure quality of practice.

Do we really want to take that away now? Years of heartless re-organisation has left many of us dedicated doctors disillusioned. Many young ones have left. Poorly trained doctors that have no right to be practising medicine now even have jobs in some of these well known hospitals. 

Can we continue to practise World Class Medicine even if we wanted to?

Back to the patient:

Would my patient be dealt with in the same way in 2015?


     GP to Paediatrician: 13 year old with one stiff arm. Seen the same day.
     Paediatrician to me: ? Psychosis or even Catatonia. 
           Seen same day and admitted to Paediatric Ward, DGH.
     Child Psychiatrist to Gynaecologist: ? Pregnancy or tumour. Still the same day.
     Gynaecologist to Radiologist: Unlikely to be pregnant, ? Ovarian cyst.
     Radiologist (Hospital & no India based): Tell tale tooth: Teratoma.
     Gynaecologist: Operation on emergency basis with Paediatric Anaethetics Consultant. Still Day 1.
     Patient unconscious and transferred to GOS on same day. Seen by various Professors.
     Patient later transferred to Queen’s Square (National Hospital for Nervous Diseases), 
             Seen by more Professors.
     Regained consciousness after 23 days.
     Eventually transferred back to local Hospital.


None of the Doctor to Doctor decisions need to be referred to managers.


We did not have Admission Avoidance then. 

How is the new Consortia going to work out the funding and how are the three Foundation Trust Hospitals going to work out the costs.


The danger is that the patient may not even get to see the first Specialist: Paediatrician not to say the second one: me.


Not to mention the operation etc. and the transfer to the Centres of excellence.



Of 100 patients with anti-NMDA-receptor encephalitis, a disorder that associates with antibodies against the NR1 subunit of the receptor, many were initially seen by psychiatrists or admitted to psychiatric centres but subsequently developed seizures, decline of consciousness, and complex symptoms requiring multidisciplinary care. While poorly responsive or in a catatonic-like state, 93 patients developed hypoventilation, autonomic imbalance, or abnormal movements, all overlapping in 52 patients. 59% of patients had a tumour, most commonly ovarian teratoma. Despite the severity of the disorder, 75 patients recovered and 25 had severe deficits or died.

Post Script:
“Ten years later mother came to see my secretary and left a photo. It was a photo of her daughter and her new baby. She had been working at the local bank since she left school, met a very nice man and now she had a baby. Mother thought I might remember them and perhaps I would be pleased with the outcome.

I was very pleased for them too but I would hate for anyone to put faith or god to such a test too often.”

Can it be that it was all so simple then
Or has time rewritten every line
If we had the chance to do it all again

Medicine & Orthodoxy: Heresy & Knowledge!


It is often inconceivable that a small bird of the warbler family can play host to the Cuckoo, which obviously outsizes it by at least three to four times.


Collared Redstart©2008 Am Ang Zhang
This picture was taken in Panama, famed for the abundance of different bird species and as far as I know there are 14 species of Cuckoos in the country.

“It is as foolish to chuck out the old as it is to fully embrace the new.” 

My early guru was referring to the changes happening in the field of psychiatry as the new benzodiazepines were being introduced. How right he was and the same view could well apply to other branches of medicine as well as psychiatry today.

“There is much we can learn from the past. One may even save a life.” 
A Brief History of Time: CPR (Cardiopulmonary Resuscitation)
We have come full circle to some ancient Chinese CPR practice going as far back as 403 B.C.




I mentioned in passing in my book “The Cockroach Catcher” Jenner’s observation and the stir it caused. When I visited his home in Glouscestershire, the curator of the small museum, who was extremely knowledgeable, took pride in telling us how Jenner’s great work on Cowpox vaccination upset the medical establishment on the one hand, and how his observation on the murderous ways of the Cuckoo newborns upset the gentlemanly world of the Ornithologists on the other. It was the Royal Society that awarded him a Fellowship for his keen observation.


©2015 Am Ang Zhang
His work on Cowpox vaccination in the prevention of Smallpox was met with hostile responses. The medical world that was dominated by London at the time could not accept that a country doctor had made such an important discovery. Jenner was publicly humiliated when he brought his findings to London. However, what he discovered could not be denied and eventually his discovery was accepted – a discovery that was to change the world.


It is worth having another look at Brian Martin’s view on:
Dissent and heresy in medicine.
 

Social Science and Medicine, vol. 58, 2004, pp. 713-725.

Brian Martin is Professor of Social Sciences in the School of Social Sciences, Media and Communication at the University of Wollongong, Australia.

Brian uses models on politics and religion to illustrate the model of orthodoxy versus dissent/heresy. You can read his views here.

He noted that challenges from the inside - heresy and dissent - are far more threatening to an establishment than outside challenges. This is true of all establishments, not least medicine.

But why should it be? In a more co-operative environment, these differences become opportunities for learning. Medicine in particular will not progress if all dissenting views are suppressed and smallpox may have indeed killed for another 20 or 30 years or more.

After the discussion on politics and religion he turned his focus medicine.
He then analysed some methods of domination in medical research:


• State power
• Training
• Restriction on entry
• Career opportunities
• Research resources
• Editorial control
• Incentives
• Belief system
• Peer pressure


“Training to become a doctor is a process of enculturation and indoctrination. The heavy work-load of memorisation and intensive practical work discourages independent thinking.”

“Examinations provide a screening process that encourages orthodoxy. For those who pursue a research path through the PhD, the process of writing a thesis or dissertation further weeds out those who might challenge orthodoxy. Some dissidents and even fewer heretics may slip through the training and credentialing system, but then there are few desirable career paths.”

“In order to have a chance, dissidents and heretics need to understand that science and medicine are systems of knowledge intertwined with power, and that if their alternative relies entirely on knowledge, without a power base, it is destined for oblivion.”

Fremantle: Medical Heresy & Nobel

Peptic ulcer – an infectious disease!
In 2005, Nobel Prize in Physiology or Medicine went to Barry Marshall and Robin Warren, who with tenacity and a prepared mind challenged prevailing dogmas. By using technologies generally available (fibre endoscopy, silver staining of histological sections and culture techniques for microaerophilic bacteria), they made an irrefutable case that the bacterium Helicobacter pylori is causing disease. By culturing the bacteria they made them amenable to scientific study.
In 1982, when this bacterium was discovered by Marshall and Warren, stress and lifestyle were considered the major causes of peptic ulcer disease. It is now firmly established that Helicobacter pylori causes more than 90% of duodenal ulcers and up to 80% of gastric ulcers. The link between Helicobacter pylori infection and subsequent gastritis and peptic ulcer disease has been established through studies of human volunteers, antibiotic treatment studies and epidemiological studies.
Difficult 10 years:
The medical establishment was difficult to persuade - everyone accepted that ulcers were caused by acid, stress, spicy foods, and should be treated by drugs blocking acid production. The big Pharmas were not happy to see any change as patients will have to take medication for life.


He went to the US to try and persuade the US doctors.

A big battle was still going on. I went to America to fight the battle there, because unfortunately the American medical profession was extremely conservative: ‘If it hasn’t happened in America, it hasn’t happened’. We needed people in the United States to take the treatment which we had developed.



“Ideas without precedent are generally looked upon with disfavour 
and men are shocked if 
their conceptions of an orderly world are challenged.” 

Bretz, J Harlen 1928. Dry Falls-Thinking Outside The Box


Also, thinking out of the box can be a good idea. Sometimes it’s better not to know all the dogma, all the things about a very difficult disease. If it’s very difficult, that means people have been working on it for years and they haven’t figured out the cure, which means they haven’t figured out the cause. So having all that knowledge that’s been accumulated in the last 10 or 20 years is really not an advantage, and it’s quite good to go and tackle a problem with a fresh mind when no-one else has had any luck.

From a doctor friend:

The Cockroach Catcher has evoked many images, memories, emotions from my own family circumstances and clinical experience.

Your pragmatic approach to problem solving and treatment plans is commendable in the era of micro-managed NHS and education system. I must admit that I learn a great deal about the running of NHS psychiatric services and the school system.

Objectively, a reader outside of the UK would find some chapters in the book intriguing because a lot of space was devoted to explaining the jargons (statementing, section, grammar schools) and the NHS administrative systems. Of course, your need to clarify the peculiar UK background of your clinical practice is understandable.

Your sensitivity and constant reference to the feelings, background and learning curves of your sub-ordinates and other members of the team are rare attributes of psychiatric bosses, whom I usually found lacking in affect! If more medical students have access to your book, I'm sure many more will choose psychiatry as a career. The Cockroach Catcher promotes the human side of clinical psychiatric practice in simple language that an outsider can appreciate. An extremely outstanding piece of work indeed.           More>>>>

The Hong Kong Paradox: Poor Air Quality & Longevity.


We all know about the French Paradox by now and basically, by right the French for what they eat should have the highest heart disease rates despite their fondness of cheeses and dare we mention Foie Gras. At least we now have some idea that it was the trans fat that is the culprit. Then there was a hint that it could be the red wine and when a programme was shown in the US, within a year, red wine sale went up 44%. The rest as they say is history.

What about the Hong Kong Paradox?

No, I am not talking about SIDS, yes, it was a bit of a paradox. Nor am I talking about the low infant mortality rate of 1.3 per thousand. That would be seen as a paradox from the point of view of countries like US or UK. Well the paradox is that the doctors used to be trained in specialism in the UK.

But unlike red wine, I doubt if anyone is going to take up this paradox.

On a good day in Autumn© 2013 Am Ang Zhang

As China is now the main manufacturing country for the rest of the world, it is only obvious that its factories pump out all sorts. Hong Kong in the autumn and winter months suffer from serious air pollution. Every medical research would confirm your suspicion, it is bad for health. But wait:


Hong Kong’s women and men enjoy the longest life expectancy in the world, according to data released by Japan’s health and welfare ministry on Wednesday.

The average lifespan for women in Hong Kong is 87.32 years, and local men on average can expect to live to 81.24. Japanese women took second place at 87.05, while Icelandic and Swiss men shared the second position in the men’s category at 81 years.

The overall life expectancy gap between women and men fell by 0.07 year last year, compared with the previous year’s figures.

Polluted air anyone? Good for longevity.
