REMEMBERING PROF. K.N. SINHA FOR HIS ASTUTE MENTORSHIP

 


Prof. Krishna Nand Sinha was our teacher in the Department of Surgery in King George’s Medical College, Lucknow. He was a Cardio-thoracic surgeon and an outstanding one. I remember assisting him, Dr. Vijay Dikshit and Dr. Vijay Mohan Kohli in many experimental open heart surgeries in dogs before he conducted the first open heart surgery in a patient in 1980, and the first Coronary Artery Bypass Grafting in 1981. We all stayed up all night in the post operative ward. He had keen interest in video assisted thoracoscopic surgery and also started the first pacemaker implantation programme in KGMC. The cardiologists picked it up much later. He was a methodical teacher and a very keen observer of human behaviour. He retired as the Head of the Department of Surgery in 1998.


He was my thesis guide when I was doing my M.S. in Surgery. I was attracted to him because of his sagacious nature and calm attitude. He talked slowly and his thoughts were invariably profound. He understood that the thesis was an occasion to familiarize me with surgical research – how to select an interesting research hypothesis which would later give me the opportunity to make a good podium presentation and result in publication of a few worthwhile research publications was his top most priority.

 

I was the first person in my family to become a doctor, and so unlike a few of my friends, I did not have the necessary mentorship at home to guide my medical career. Prof. Sinha filled that void admirably. He was my mentor, my philosopher and my guide. He was of the opinion that a research thesis must satisfy a few criteria

1.       It must be a topic that relates to public health of our part of the country

2.       It should involve a recent investigative modality that is of current interest to              the journal editors

3.       It should teach me a new skill

After going through many testable assumptions we zeroed in on ‘The effects of tobacco chewing on esophageal mucosa – a clinical, histological and ultrastructural study’.  Because we would be studying the esophagus, in the same set of patients we planned to study the oral and pharyngeal mucosa too so that this data could help us to compare it with esophageal mucosa and also document it separately into two more research papers.

 

True to his meticulous planning, I learnt a new skill – the use of both rigid and flexible endoscopes for performing esophagoscopy. Prof. Sinha made me assist 50 cases before allowing me to introduce the endoscope under his expert supervision. I learned to sprinkle Lugol's Iodine on the esophageal mucosa and biopsy the suspicious areas in the upper, middle and lower third of the esophagus. He then showed me how the gastro-esophageal junction looked and how the stomach mucosa was completely different. He also demonstrated foreign bodies and malignancies and corrosive strictures in his clinical patients, who had nothing to do with my research. He introduced me to his senior Prof. Pramod Nath, who in turn showed me what an electron microscope looks like and later what ultrastructural changes tobacco was producing on the esophageal mucosa.

 

While to most of my colleagues thesis was a huge burden, over and above their clinical work load, because of Prof. Sinha, my thesis was perhaps one of the most enjoyable parts of my post graduation days. He was a tough task master and those were pre computer days. He made me rewrite my 120 page thesis 14 times before approving it, but the bonus of this hard work was that I had three indexed publications from my thesis, one before my M.S. examinations. His benevolence and kindness was exemplified by the fact that I was the first author in all three papers.


Prof. Sinha, Prof. N.C. Misra and later Prof. S.K. Bhatnagar were the outstanding troika who emphasized upon me the value of research and publications. Prof. Sinha would often remind me that while others will approach a job interview with the reference of their influential father and father-in-law, your publications will be your calling cards, and they will be very hard to ignore. He taught me how to choose a journal for publication, what an indexed journal was, how to respectfully respond to reviewers and how to handle rejection, modify the paper and promptly send it to another and better journal.

 

Even after my M.S. days I remained in close touch with Prof. Sinha. He and his wife, Prof. Preeti Sinha, who was in Lucknow University,  stayed in Mahanagar, very close to my place, and his continued mentorship was priceless. After I returned from my overseas training and started my practice, a senior teacher, who was practicing in a hospital in Mahanagar, invited me to start my practice in his hospital. I went to Prof. Sinha for his advice. He looked at me for some time, smiled, and said “Nothing ever grows under a Banyan tree.” This sagacious insight, astute perception, and erudite understanding of such delicate matters was the hallmark of his wonderful mentorship.

 

I often remember my teachers by their lectures, but with Prof. K.N. Sinha I will make an exception. I will try to recall a long conversation I had with him one morning, while sitting in his lawn, and later, when the sun got the better of us, in the lounge room.

 

He was trying to emphasize to me that success in profession and in life are not very different. Those who achieve one and not the other, or those who achieve one at the cost of the other, have really got it wrong. Striving for success is a trait many people share but don’t always know how to accomplish. This need to succeed causes almost everyone to try their best, however, after some times, while some are reaching their goals, others still find themselves tired, exhausted and still lagging far behind. So, there was no dearth of effort in them, but perhaps not in the right direction.

 

If you feel stuck in place, stagnating in life, the "5-Hour Rule" can help you get out of this situation, he said. “What is the 5-hour rule” I asked.  As its name implies, the 5-hour rule speaks of a dedication of 5 hours a week, or one hour per day of work, to deliberate learning and self-improvement. This means that in order to succeed, you have to leave yourself 5 hours a week and devote your attention to learning only, without distractions or excuses. Not everyone learns in the same way, but there are several methods to do this to produce the best results from the process and to understand what you need to change in order to be more successful:

 

1. Reading

The hobby of reading is shared by many successful people. Swami Vivekananda, Ishwar Chandra Vidyasagar and Sarvapalli Radhakrishnan were all avid readers.  They all attributed their success to their reading habit which ensured that their learning never ended. In order to make sure you read and grow, always keep a book in the bag you carry around, set reading goals like several hours or several pages a day, and do your best to meet them.

In today’s day and age, we also have the option to read books on our cell phones or portable tablets, making reading books that much easier. This is one habit that has never deserted me.

 

2. Thinking 

When you truly want to learn instead of just read, you have a very different mindset. Instead of approaching a book as “I need to finish this” you instead say “I’m going to master this. I’m going to know this like the back of my hand. Understanding what you have read and the information you’ve collected is a key condition for success and learning. When you spend time reading to learn and improve yourself, it is also important that you take the time to understand what you have read so that you don’t feel overwhelmed and tired. It is essential that you spend the time to cut off distractions when internalizing this information. A good way to do this is to keep a journal that will help you process your feelings and thoughts. Writing a summary of what you have read will also help you process the things you’ve learned and apply them to your work or any other field you wish to succeed in.

 

3. Experiment / Practice

Once you have begun to learn and understand what you need to do to get ahead and succeed, you can start the practical stage; make time for yourself every week or day to try theories or ideas you have. It could be a project in a job you've struggled with which you've found an interesting way to do or anything else you want to succeed in. When it comes to practical experience, there are no bad ideas, and experimenting with different things, "crazy" as they may be, will allow you to test what works and what doesn’t. A surgeon should practice a new idea again and again in the mind, before translating it in clinical practice. When you find what works, you can apply it to the "real world," that is, at work or other places where you are struggling to succeed.

It is also vital to learn from the mistakes of others because none of us will live long enough to do all the mistakes ourselves and learn from them.

 

4. Don’t confuse working with learning

It is easy to confuse work with learning, and when we do, people begin to feel that they are standing in the same place and stagnating. It is important that you realize that investing many hours at work is not what will guarantee you success in the future. When you begin to devote time to learning and not just to work, you can develop significantly. This way you will focus not only on your daily problems but also on the future and on the way you can strive for it and your goals successfully. Set apart time for deliberate learning so that you’re not only consumed with work, but also with other important things that can push you forward in life.

 

5. Focous on self-improvement rather than just productivity

People often mistakenly think that having a product of their actions means being successful, but that isn’t true. Success in life is not measured only by material achievements that can disappear in an instant, but in constant improvement. Achievements are important, but try not to focus only on them and what you have at a given moment, but on what you will gain in the long run.  

 

The biggest challenge in the 5-hour rule is perseverance since people are constantly out to reap rewards and good outcomes. However, when that doesn’t happen they may give up and make mistakes that will only push them further away from their goal. To make sure this doesn’t happen to you, try to focus on learning and improving yourself, not just on the number on your paycheck, for example. When you learn that you can do things much more complicated than you thought you were capable of before, success will come in a way you could never imagine. For a surgeon, this is priceless!

 

The next time you pick up a book that you believe will be helpful to you at work or in life, slow down. Take notes. Don’t finish the book until you feel you have a mastery-level understanding of the concepts. Then build a plan for how you’re going to implement these concepts. It’ll take you twice the time but give you ten times the return. And, that is how our morning discussion on self improvement culminated.
