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.

Daily meditation can help improve mood and sleep in teenagers suffering or recuperating from cancer, a promising research shows.

Mindfulness-based meditation could lessen some symptoms associated with cancer in teenagers, according to the results of a clinical trial intervention led by researchers at University of Montreal and its affiliated CHU Sainte-Justine children’s hospital.

The process focuses on the present moment and the connection between the mind and body.

Adolescents living with cancer face not only the physical symptoms of their condition but also the anxiety and uncertainty related to the progression of the disease and the anticipation of physical and emotional pain related to illness and treatment.

The researchers asked 13 adolescents with cancer to complete questionnaires covering mood (positive and negative emotions, anxiety and depression), sleep and quality of life.
The group was divided in two. The first group of eight adolescents were offered eight mindfulness-based meditation sessions and the remaining five adolescents in the control group were put on a wait-list.

After the last meditation session, patients from both groups filled out the same questionnaires a second time.

“We found that teenagers that participated in the mindfulness group had lower scores in depression after our eight sessions. Girls from the mindfulness group reported sleeping better. We also noticed that they developed mindfulness skills to a greater extent than boys during the sessions,” explained Catherine Malboeuf-Hurtubise from University of Montreal.
