One thing which is most frequently associated with a doctor is a stethoscope. Be it advertisements or real life, a stethoscope is one thing which we see hanging around every doctor’s neck.

The stethoscope is an instrument which is used by doctors to hear a patient’s heartbeats and to check their breathing. This medical instrument is used to hear the resonance of sounds made by our hearts and lungs for evaluative purposes. The instrument has been an object of fascination for a long time, because of its simple design, which consists of just a resonator and two tubes.

But who invented the stethoscope?

René-Théophile-Hyacinthe Laennec or simply known as Rene Laennec, was a French physician who invented stethoscope in the year, 1816. He invented this medical instrument while working at the Necker Hospital in France, and used it in diagnosing various chest and lung conditions, pioneering the whole concept.

He was born on February 17, 1781, Brittany, France and died on August 13, 1826, Kerlouanec due to Tuberculosis.

Necessity for this invention

Rene Laennec invented stethoscopic or stethoscope because of his embarrassment while treating women. He didn’t like to put his ear at their chest in order to diagnose their problems, especially in the case of overweight women. He also found this method of listening to heartbeats very ineffective.

As a result, he invented an instrument which won’t require him to put his ear on his patient’s chest and will be more effective. He rolled a piece of paper into a cylinder and placed one side on the patient’s chest and the other near his ear. He found that he could hear the sounds better.

His contributions to the Medical Field 

He invented the stethoscope but that wasn’t his only major contribution or achievement in the medical field.

He famously coined the term ‘melanoma’, which is a type of cancer that typically occurs in the skin but rarely occur in the mouth or intestines. He was the one who recognised that melanotic lesions are the result of metastatic melanoma.

Laennec is also well known for his studies of peritonitis, amenorrhea and tubercle lesions. He also coined the term cirrhosis, which is a lung disease. His works played a huge role in the understanding the of this disease.

A difference in the design of Traditional and Modern Stethoscopes

The modern stethoscopes that we see today are not what Rene Laennec invented. His original design was rather simple. The doctor’s stethoscope that we see today is much more complex that Laennec’s simple design.

His original design was just a tube, which could be made of wood and copper. It could be assembled and dissembled easily as per the convenience of the physician. The new age stethoscope is a modification of his original design.

His original stethoscope was replaced by the stethoscopes using rubber tubes by end of the 19th century.

Achievements

The government of France honoured Rene Laennec with First Prize in Medicine and Sole Prize in Surgery in 1803.

He was also conferred with the title of the ‘Knight of the Legion of Honor’ in 1824.

His contributions in the medical fields are immense and for it, he will always be remembered.

High carbohydrate intake may increase cancer recurrence risk

Five-year survival rates among these patients continue to be low, in part because these cancers are often detected in the later stages

Consuming high amounts of carbohydrates and sugar prior to treatment for head and neck cancer may increase the patients’ risks of cancer recurrence and mortality, a new study reports.

Patients who consumed the most total carbohydrates and sugars — in the form of sucrose, fructose, lactose and maltose — in the year preceding the cancer treatment were at greater risk of mortality from any cause during the follow-up period. Out of the 400 cancer patients in the study, published in the International Journal of Cancer, more than 17 per cent experienced recurrence of their cancer, and 42 patients died from it.

Associations among carbohydrate intake and patient outcomes differed by cancer type and stage, said lead author Anna E. Arthur, professor at the University of Illinois at Urbana-Champaign.

However, eating moderate amounts of fats and starchy foods such as whole grains, potatoes and legumes after treatment could have protective benefits, reducing the patients’ risks of disease recurrence and death, he added.

What We Know About Cancer Risk and Coffee

“Our results, along with the findings of other studies, suggest that diet composition can affect cancer outcomes,” said co-author Amy M. Goss, professor at the University of Alabama.

Higher mortality rates were found among people with oral cavity cancer who consumed the greatest amounts of total carbohydrates, total sugars and simple carbohydrates, but the researchers found no such associations among people who had oropharyngeal cancers.

Chronic diseases are not yet included in cancer prevention schemes.
Cancer can be caused due to too much sugar.

“Although in this study we found that higher total carbohydrate and total sugar were associated with higher mortality in head and neck cancer patients, because of the study design we can’t say that there’s a definitive cause-effect relationship,” Arthur said.

Five-year survival rates among these patients continue to be low, in part because these cancers are often detected in the later stages, putting patients at high risk of recurrence, the researchers said. IANS

One response to “High carbohydrate intake may increase cancer recurrence risk”

  1. I was about to take Cruise Ship Management in school last year. But unfortunately, when I received the result in hepatitis b test, it was positive. I don’t know where I got this. I’ve never experienced having sex with any man or boyfriend. I was so disappointed at that time. But then again, it is never the end of the world. I repeated the test in a well-known hospital. But, it came back positive again. Early this year i purchase Hepatitis B herbal remedy online from BEST HEALTH HERBAL CENTRE. They told me i will be negative after 4-5 weeks of usage of their Hepatitis B herbal remedy, which i believed and have faith. After 5 weeks of usage, I did another test my HBsAg came negative in routine checkup, so I have done all investigations for hepatitis B. My test reports are HBsAg negative 0.04 on 22/02/2018. I will never stop telling the world about BEST HEALTH HERBAL CENTRE good work in human life .
