Two Accidental Discoveries in Healthcare
Introduction
The field of medicine contains a
plethora of therapies that started as accidental discoveries. Many of the
treatments used today resulted from observing nature and exploring the observed
causes. For example, in the 1700s, Edward Jenner noticed that milkmaids
appeared immune to Smallpox. Through observation and experimentation, he
discovered that Coxpox proved effective in preventing Smallpox, which was the
beginning of vaccinations (Stewart & Devlin, 2006). The pattern of
observation and discovery in healthcare continues today.
The Warfarin Discovery
Warfarin is a medication used to
prevent blood clots and treats various medical conditions such as deep vein
thrombosis and pulmonary emboli. Without the discovery of Warfarin, cardiac
valve replacement surgery and ventricular assist devices would not exist.
In the 1920s, a catastrophic
hemorrhagic illness caused many cattle deaths in the mid-western United States.
Farmer's were troubled by the uncontrolled and unexplained bleeding in cattle after
a minor surgical procedure or birth. This disease puzzled scientists and
farmers because the animals appeared healthy until injured. Dr. Frank
Schofiled, a veterinarian, grew curious about the condition called Sweet Clover
Disease and discovered moldy hay eaten by cows contributed to the syndrome (Meek, 2013).
The mold's causative agent
responsible for the bleeding remained elusive until Dr. Karl Paul Link, a
chemist, isolated Dicumarol from the mold. The discovery of Dicumarol leads to
the synthesis of Warfarin Sodium, also known as Coumadin (Hall & Wilkins, 2005).
The scientist's investigations
started with an inquiry into the cause of hemorrhagic disease in cattle and
resulted in a life-changing discovery. Today, Coumadin remains one of the most
critical medications available to physicians in treating disease and is listed
on the World Health Organizations' list of 100 essential medications (Pirmohamed, 2006).
From Chemical Warfare to Hope
Mustard
gas is a chemical used as an area denial weapon and first saw use in the
trenches during World War One. The gas causes horrific blisters resulting in
chemical burns to the skin and lungs, leading to death in the unlucky and
permanent blindness in the survivors (Duchovic & Vilensky, 2007). However, the mechanism behind
the gruesome injuries remained elusive until the discovery of deoxyribonucleic
acid.
On
December 2nd, 1943, an attack by the Luftwaffe on the port of Bari,
Italy, resulted in 617 injuries and 83 deaths resulting from Mustard Gas
exposure (Conant, 2020).
The cause of death and injuries remained a secret until after the end of the War.
The investigating officer, Colonel Cornelius Rhoads, observed victims who
initially survived the original injuries subsequently died of various blood
dyscrasias. During autopsies, Dr. Rhoads discovered bone marrow depletion in
the victims (Plunkett, 2014).
The incident resulted
in the accidental discovery of chemotherapy and led to the modern treatment of
cancer (Conant, 2020).
Dr. Rhoads convinced General Motors founders Alfred Sloane and Charles
Kettering to establish the Sloan Kettering Institute for Cancer Research (Conant, 2020).
The institution explored mustard gas analogs and medical applications that
persist to this day in cancer treatment.
Today, the healthcare
industry frequently looks to nature for solutions to treat disease. Many of
these discoveries are incidental observations that result in medical advances.
Those discoveries improve the quality of life and offer hope where none
previously existed.
