How a Deadly Fire Gave Birth to Modern Medicine
On the evening of November 28, 1942, more than 1,000 revelers from the Boston College-Holy Cross football game jammed into the Cocoanut Grove, Boston's oldest nightclub. When a spark from faulty wiring accidently ignited an artificial palm tree, the packed nightspot, which was only designed to accommodate about 500 people, was quickly engulfed in flames. In the ensuing panic, hundreds of people were trapped inside, with most exit doors locked. Bodies piled up by the only open entrance, jamming the exits, and 490 people ultimately died in the worst fire in the country in forty years.
"People couldn't get out," says Dr. Kenneth Marshall, a retired plastic surgeon in Boston and president of the Cocoanut Grove Memorial Committee. "It was a tragedy of mammoth proportions."
Within a half an hour of the start of the blaze, the Red Cross mobilized more than five hundred volunteers in what one newspaper called a "Rehearsal for Possible Blitz." The mayor of Boston imposed martial law. More than 300 victims—many of whom subsequently died--were taken to Boston City Hospital in one hour, averaging one victim every eleven seconds, while Massachusetts General Hospital admitted 114 victims in two hours. In the hospitals, 220 victims clung precariously to life, in agonizing pain from massive burns, their bodies ravaged by infection.

Tragic Losses Prompted Revolutionary Leaps
But there is a silver lining: this horrific disaster prompted dramatic changes in safety regulations to prevent another catastrophe of this magnitude and led to the development of medical techniques that eventually saved millions of lives. It transformed burn care treatment and the use of plasma on burn victims, but most importantly, it introduced to the public a new wonder drug that revolutionized medicine, midwifed the birth of the modern pharmaceutical industry, and nearly doubled life expectancy, from 48 years at the turn of the 20th century to 78 years in the post-World War II years.
The devastating grief of the survivors also led to the first published study of post-traumatic stress disorder by pioneering psychiatrist Alexandra Adler, daughter of famed Viennese psychoanalyst Alfred Adler, who was a student of Freud. Dr. Adler studied the anxiety and depression that followed this catastrophe, according to the New York Times, and "later applied her findings to the treatment World War II veterans."
Dr. Ken Marshall is intimately familiar with the lingering psychological trauma of enduring such a disaster. His mother, an Irish immigrant and a nurse in the surgical wards at Boston City Hospital, was on duty that cold Thanksgiving weekend night, and didn't come home for four days. "For years afterward, she'd wake up screaming in the middle of the night," recalls Dr. Marshall, who was four years old at the time. "Seeing all those bodies lined up in neat rows across the City Hospital's parking lot, still in their evening clothes. It was always on her mind and memories of the horrors plagued her for the rest of her life."
The sheer magnitude of casualties prompted overwhelmed physicians to try experimental new procedures that were later successfully used to treat thousands of battlefield casualties. Instead of cutting off blisters and using dyes and tannic acid to treat burned tissues, which can harden the skin, they applied gauze coated with petroleum jelly. Doctors also refined the formula for using plasma--the fluid portion of blood and a medical technology that was just four years old--to replenish bodily liquids that evaporated because of the loss of the protective covering of skin.
"Every war has given us a new medical advance. And penicillin was the great scientific advance of World War II."
"The initial insult with burns is a loss of fluids and patients can die of shock," says Dr. Ken Marshall. "The scientific progress that was made by the two institutions revolutionized fluid management and topical management of burn care forever."
Still, they could not halt the staph infections that kill most burn victims—which prompted the first civilian use of a miracle elixir that was being secretly developed in government-sponsored labs and that ultimately ushered in a new age in therapeutics. Military officials quickly realized this disaster could provide an excellent natural laboratory to test the effectiveness of this drug and see if it could be used to treat the acute traumas of combat in this unfortunate civilian approximation of battlefield conditions. At the time, the very existence of this wondrous medicine—penicillin—was a closely guarded military secret.
From Forgotten Lab Experiment to Wonder Drug
In 1928, Alexander Fleming discovered the curative powers of penicillin, which promised to eradicate infectious pathogens that killed millions every year. But the road to mass producing enough of the highly unstable mold was littered with seemingly unsurmountable obstacles and it remained a forgotten laboratory curiosity for over a decade. But Fleming never gave up and penicillin's eventual rescue from obscurity was a landmark in scientific history.
In 1940, a group at Oxford University, funded in part by the Rockefeller Foundation, isolated enough penicillin to test it on twenty-five mice, which had been infected with lethal doses of streptococci. Its therapeutic effects were miraculous—the untreated mice died within hours, while the treated ones played merrily in their cages, undisturbed. Subsequent tests on a handful of patients, who were brought back from the brink of death, confirmed that penicillin was indeed a wonder drug. But Britain was then being ravaged by the German Luftwaffe during the Blitz, and there were simply no resources to devote to penicillin during the Nazi onslaught.
In June of 1941, two of the Oxford researchers, Howard Florey and Ernst Chain, embarked on a clandestine mission to enlist American aid. Samples of the temperamental mold were stored in their coats. By October, the Roosevelt Administration had recruited four companies—Merck, Squibb, Pfizer and Lederle—to team up in a massive, top-secret development program. Merck, which had more experience with fermentation procedures, swiftly pulled away from the pack and every milligram they produced was zealously hoarded.
After the nightclub fire, the government ordered Merck to dispatch to Boston whatever supplies of penicillin that they could spare and to refine any crude penicillin broth brewing in Merck's fermentation vats. After working in round-the-clock relays over the course of three days, on the evening of December 1st, 1942, a refrigerated truck containing thirty-two liters of injectable penicillin left Merck's Rahway, New Jersey plant. It was accompanied by a convoy of police escorts through four states before arriving in the pre-dawn hours at Massachusetts General Hospital. Dozens of people were rescued from near-certain death in the first public demonstration of the powers of the antibiotic, and the existence of penicillin could no longer be kept secret from inquisitive reporters and an exultant public. The next day, the Boston Globe called it "priceless" and Time magazine dubbed it a "wonder drug."
Within fourteen months, penicillin production escalated exponentially, churning out enough to save the lives of thousands of soldiers, including many from the Normandy invasion. And in October 1945, just weeks after the Japanese surrender ended World War II, Alexander Fleming, Howard Florey and Ernst Chain were awarded the Nobel Prize in medicine. But penicillin didn't just save lives—it helped build some of the most innovative medical and scientific companies in history, including Merck, Pfizer, Glaxo and Sandoz.
"Every war has given us a new medical advance," concludes Marshall. "And penicillin was the great scientific advance of World War II."
Short-Term Suspended Animation for Humans Is Coming Soon
At 1 a.m., Tony B. is flown to a shock trauma center of a university hospital. Five minutes earlier, he was picked up unconscious with no blood pressure, having suffered multiple gunshot wounds with severe blood loss. Standard measures alone would not have saved his life, but on the helicopter he was injected with ice-cold fluids intravenously to begin cooling him from the inside, and given special drugs to protect his heart and brain.
Suspended animation is not routine yet, but it's going through clinical trials at the University of Maryland and the University of Pittsburgh.
A surgeon accesses Tony's aorta, allowing his body to be flushed with larger amounts of cold fluids, thereby inducing profound hypothermia -- a body temperature below 10° C (50° F). This is suspended animation, a form of human hibernation, but officially the procedure is called Emergency Preservation and Resuscitation for Cardiac Arrest from Trauma (EPR-CAT).
This chilly state, which constitutes the preservation component of Tony's care, continues for an hour as surgeons repair injuries and connect his circulation to cardiopulmonary bypass (CPB). This allows blood to move through the brain delivering oxygen at low doses appropriate for the sharply reduced metabolic rate that comes with the hypothermia, without depending on the heart and lungs. CPB also enables controlled, gradual re-warming of Tony's body as fluid and appropriate amounts of red blood cells are transfused into him.
After another hour or so, Tony's body temperature reaches the range of 32-34° C (~90-93° F), called mild hypothermia. Having begun the fluid resuscitation process already, the team stops warming Tony, switches his circulation from CPB to his own heart and lungs, and begins cardiac resuscitation with electrical jolts to his heart. With his blood pressure stable, his heart rate slow but appropriate for the mild hypothermia, Tony is maintained at this intermediate temperature for 24 hours; this last step is already standard practice in treatment of people who suffer cardiac arrest without blood loss trauma.
The purpose is to prevent brain damage that might come with the rapid influx of too much oxygen, just as a feast would mean death to a starvation victim. After he is warmed to a normal temperature of 37° C (~99° F), Tony is awakened and ultimately recovers with no brain damage.
Tony's case is fictional; EPR-CAT is not routine yet, but it's going through clinical trials at the University of Maryland and the University of Pittsburgh, under the direction of trauma surgeon Dr. Samuel Tisherman, who spent many years developing the procedure in dogs and pigs. In such cases, patients undergo suspended animation for a couple of hours at most, but other treatments are showing promise in laboratory animals, like the use of hydrogen sulfide gas without active cooling to induce suspended animation in mice. Such interventions could ultimately fuse with EPR-CAT, sending the new technology further into what's still the realm of science fiction – at least for now.
Consider the scenario of a 5-year-old girl diagnosed with a progressive, incurable, terminal disease.
Experts say that extended suspended animation – cooling patients in a stable state for months or years -- could be possible at some point, although no one can predict when the technology will be clinical reality, since hydrogen sulfide and other chemical tactics would have to move into clinical use in humans and prove safe and effective in combination with EPR-CAT, or with a similar cooling approach.
How Could Long-Term Suspended Animation Impact Humanity?
Consider the scenario of a 5-year-old girl diagnosed with a progressive, incurable, terminal disease. Since available treatments would only lengthen the projected survival by a year, she is placed into suspended animation. She is revived partially every few years, as new treatments become available that can have a major impact on her disease. After 35 years of this, she is revived completely as treatments are finally adequate to cure her condition, but biologically she has aged only a few months. Physically, she is normal now, though her parents are in their seventies, and her siblings are grown and married.
Such hypothetical scenarios raise many issues: Where will the resources come from to take care of patients for that long? Who will pay? And how will patients adapt when they emerge into a completely different world?
"Heavy resource utilization is a factor if you've got people hibernating for years or decades," says Bradford Winters, an associate professor of anesthesiology and critical care medicine, and assistant professor of neurological surgery at Johns Hopkins.
Conceivably, special high-tech facilities with robots and artificial intelligence watching over the hibernators might solve the resource issue, but even then, Winters notes that long-term hibernation would entail major disparities between the wealthy and poor. "And then there is the psychological effect of being disconnected from one's family and society for a generation or more," he says. "What happens to that 5-year-old waking to her retired parents and married siblings? Will her younger sister adopt her? What would that be like?"
Probably better than dying is one answer.
Back on Earth, human hibernation would raise daunting policy questions that may take many years to resolve.
Outside of medicine, one application of human hibernation that has intrigued generations of science fiction writers is in long-duration space travel. During a voyage lasting years or decades, space explorers or colonists not only could avoid long periods of potential boredom, but also the aging process. Considering that the alternative to "sleeper ships" would be multi-generation starships so large that they'd be like small worlds, human hibernation in spaceflight could become an enabling technology for interstellar flight.
Big Questions: It's Not Too Early to Ask
Back on Earth, the daunting policy questions may take many years to resolve. Society ought to be aware of them now, before human hibernation technology outpaces its dramatic implications.
"Our current framework of ethical and legal regulation is adequate for cases like the gunshot victim who is chilled deeply for a few hours. Short-term cryopreservation is currently part of the continuum of care," notes David N. Hoffman, a clinical ethicist and health care attorney who teaches at Columbia University, and at Yeshiva University's Benjamin N. Cardozo School of Law and Albert Einstein College of Medicine.
"But we'll need a new framework when there's a capability to cryopreserve people for many years and still bring them back. There's also a legal-ethical issue involving the parties that decide to put the person into hibernation versus the patient wishes in terms of what risk benefit ratio they would accept, and who is responsible for the expense and burdens associated with cases that don't turn out just right?"
To begin thinking about practical solutions, Hoffman characterizes long-term human hibernation as an extension of the ethics of cyro-preserved embryos that are held for potential parents, often for long periods of time. But the human hibernation issue is much more complex.
"The ability of the custodian and patient to enter into a meaningful and beneficial arrangement is fraught, because medical advances necessary to address the person's illness or injury are -- by definition -- unknown," says Hoffman. "It means that you need a third party, a surrogate, to act on opportunities that the patient could never have contemplated."
Such multigenerational considerations might become more manageable, of course, in an era when gene therapy, bionic parts, and genetically engineered replacement organs enable dramatic life extension. But if people will be living for centuries regardless of whether or not they hibernate, then developing the medical technology may be the least of the challenges.
The Mind-Blowing Promise of Neural Implants
You may not have heard of DARPA, the research branch of the Pentagon. But you're definitely familiar with some of the technology it has pioneered, like the Internet, Siri, and handheld GPS.
"Now we're going to try to go from this proof-of-concept all the way to commercial technologies that can powerfully affect patients' lives."
Last week in National Harbor, Maryland, DARPA celebrated its 60th anniversary by showcasing its latest breakthroughs and emerging research programs, one of which centers around using neurotechnology to enhance the capabilities of the human brain. This technology is initially being developed to help warfighters and veterans, but its success could have enormous implications for civilian patients and, eventually, mainstream consumers.
The field is moving ahead rapidly. Fifteen years ago, a monkey named Aurora used a brain-machine interface to control a cursor on a computer screen. In 2014, DARPA's mind-controlled prosthetic arm for amputees won approval from the Food and Drug Administration.
Since then, DARPA has continued to push neurotechnology to new heights. Here are three of their research programs that are showing promise in early human testing:
1) A NEURAL IMPLANT HELP MANAGE PSYCHIATRIC ILLNESS
More than 2.2 million veterans and 44 million civilians are living with some form of psychiatric illness, and medications don't work for everyone. DARPA set out to create new options for people living with debilitating anxiety, depression, and PTSD.
"We can get somebody back to normal. It's a whole new set of tools for physicians," said Justin Sanchez, Director of the Biological Technologies Office at DARPA.
He told the audience about a woman living with both epilepsy and extreme anxiety, who has a direct neural interface that reads her brain's signals in real time and can be modulated with stimulation. He shared a recent video of her testing the device:
"Now we're going to try to go from this proof-of-concept all the way to commercial technologies that can powerfully affect patients' lives," Sanchez said.
2) A NEURAL IMPLANT TO HELP IMPROVE MEMORY
"We are right at the cusp" of improving memory recall with direct neural interfaces, Sanchez said.
All day long, our brains shift between poor and good memory states. A brain-computer interface can read the signals of populations of neurons in the lateral temporal cortex. The device continuously monitors the state of the brain and delivers stimulation within a fraction of a second after detecting a poor memory state, to improve the person's memory performance.
The improved memory lasts only seconds, so the system "delivers stimulation as needed in a closed loop to keep the performance in a good state, because of this natural variability of performance," said Dan Rizzuto, founder of NiaTherapeutics, whose technology was developed with support from DARPA and the United States BRAIN Initiative.
Check out this recently shot video of a patient testing the device, which Sanchez called "a breakthrough moment":
About 400 patients have been tested with this technology so far. In a pilot study whose data have not yet been published, patients with traumatic brain injury showed improvement in recall of around 28 percent, according to Rizzuto.
He estimates that potential FDA approval of the device for patients with traumatic brain injury is still 7 to 8 years away. The technology holds the potential to help many other kinds of patients as well.
"We believe this device could also be used to treat Alzheimer's because it's not specific to any brain pathology but based on a deep understanding of the way human memory works," Rizzuto said.
3) A NEURAL IMPLANT TO REVOLUTIONIZE PROSTHETICS FOR WARFIGHTERS AND VETERANS
Since 2006, DARPA has run a program to revolutionize prosthetics. The latest advances allow amputees to actually feel again with their bionic limbs.
Sensors in a prosthetic hand relay information to an interface in the brain that allows the person to detect which of their "fingers" are being touched, while their eyes are closed:
WHAT COMES NEXT?
DARPA is now turning its attention to non-surgical, non-invasive neurotechnology. Researchers hope to use advanced sensor technology to detect signals from neurons without putting any electrodes directly inside the brain. Under the direction of program manager Dr. Al Emondi, the N³ program is about to launch soon and plans to run for four or five years.
"We haven't even scratched the surface of what a human brain's capability is," said Dr. Geoffrey Ling, the Founding Director of the Biological Technologies Office. "When we can make this a non-invasive consumer technology, this will explode. It will take on a life of its own."
Then, inevitably, the hard questions will follow.
As Sanchez put it: "Will society consider some form of neural enhancement a personal choice like braces? Could there be a disturbing gap for people who have neurotech and those who don't? We must come together and all think over the horizon. How the story unfolds ultimately depends on all of us."
