Reference excerpt

Surinder Kumar Sama (born 1934) is an Indian gastroenterologist, known for his expertise in endocrinology and diabetology. He is considered by many as the Father of Gastroenterology in India. The discovery of Non-cirrhotic portal fibrosis, an idiopathic chronic liver disease is attributed to him, which he described in a 1962 medical paper, co-authored with Ramalingaswami and Wig. The Government of India awarded him the civilian honour of the Padma Shri in 2004 for his pioneering research on liver diseases including Non-cirrhotic portal fibrosis and Hepatitis B. Sama also received the highest Indian medical honour of Dr. B. C. Roy Award in 2004.

Biography Dr. Sama was born in 1934, did his graduate studies at the All India Institute of Medical Sciences Delhi and started his career by joining his alma mater, in 1958. He stayed at AIIMS till 1974 during which time he established the Department of Gastroenterology at the institute as well as at G. B. Pant Hospital, another government hospital in the Indian capital city, even started gaining interest in Bangladesh healthcare services. In 1976, he joined Sir Ganga Ram Hospital as an honorary physician of gastroenterology and served the charitable hospital for 36 years, including as its chairman from 1995 to 2006. During this period, he founded the Gastroenterology department there which has now grown to become a centre of excellence. He held various posts at the hospital, including that of the founder member of the Board of Management. He retains the Management Board membership and is also a member of its Board of Trustees. While continuing his association with Sir Ganga Ram Hospital, he founded Sama Hospital in 1982 and is its director. Dr. Sama is considered by many as a pioneer of medical research on liver diseases in India. His 1962 article is reported to be the first attempt at describing the chronic disease of Non-cirrhotic portal fibrosis and is also credited with recognised research on Hepatitis B. His researches have been documented by over 45 articles, published in peer reviewed national and international journals. He is a former president and a life member of the Indian Society of Gastroenterology and has organised six therapeutic endoscopic workshops during his tenure there. He is also a life member of the Indian Society of Study of Liver Disease, Indian Society of Gastrointestinal Endoscopy, American Gastroenterology Association and Association of Physicians of India and was the president of the New Delhi chapter of the Indian Medical Association. He served as the personal physician to the President of India in 2001. He is also the vice president of the Managing Committee of DAV College. He has delivered several award lectures such as Presidential Oration (1986), Dr. B. L. Kapur Memorial Oration (1991), Dr. K. L. Wig Memorial Oration (2002) and Dr. R. S. Tiwary Oration (2005). Dr. Sama, a Fellow of the World Health Organization and the National Academy of Medical Sciences, received Dr. B. C. Roy Award, the highest Indian award in the medical category, from the Medical Council of India in 2004. The Government of India awarded him the civilian honour of the Padma Shri in 2004 and the International Association for Preventive Cardiology honoured him with their Lifetime Achievement Award in 2006. He is also a recipient of several other awards such as Punjab Rattan Award, DMA Ratna Award, Bharat Jyoti Award, Bhaskar Award, Human Care Award and Delhi Rattan Award.

Worked examples

Example 1 — a first encounter with S. K. Sama

Start with the simplest possible case. Write down what S. K. Sama claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to S. K. Sama before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about S. K. Sama ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of S. K. Sama

In research: S. K. Sama appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses S. K. Sama in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: S. K. Sama is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1934 births, 20th-century Indian medical doctors, Academic staff of the All India Institute of Medical Sciences, New Delhi, so understanding it makes those chapters shorter.
In everyday life: Look for S. K. Sama outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
