Your Eye Drops Can Kill You

180312-eye-drops-cure-need-for-glasses-feature

Anything can be a poison, it all depends on the dose. This includes the drops you use to clear your eyes. 

The active, and dangerous, ingredient in many of these preparations is tetrahydrozoline hydrochloride. If ingested in sufficient amounts, it can elevate the blood pressure, drop the heart rate to dangerously low levels, reduce body temperature, and cause nausea, vomiting, shortness of breath, blurred vision, an unsteady gait, seizures, coma, and death. And you thought those little dropper bottles were harmless.

In a new case, it appears that Lana Clayton killed her husband by adding a few drops to his water over several days. He apparently fell down the stairs. Since this chemical causes walking difficulties, blurred vision, and even seizures, he could easily have staggered and fallen down the steps. Or even been pushed. Regardless, a significant amount of the chemical was found in his blood at autopsy.

I’ve blogged about this before in discussing a case of possible munch Munchausen By Proxy. Samantha Elizabeth Unger apparently poisoned her children by adding a few drops of the medication to their juice on multiple occasions. Here is the link to that post:

Criminal Mischief #02: Cause and Manner of Death Notes

Criminal Mischief #02: The ME’s 3 most important determinations: Cause, Manner, and Time of Death

Part I: Cause and Manner of Death Notes

CAUSE/MECHANISM OF DEATH:

Cause of death is why the individual died
Heart attack, GSW, traumatic brain injury, diseases

Mechanism-physiological derangement that causes death

One cause—several mechanisms

Example: MI-arrhythmia, cardiogenic shock, rupture 

Example: GSW—heart or brain damage, exsanguination. wound infection

One mechanism—several causes

Example: Exsanguination—GSW, ulcer, meds, disease 

Just as a cause of death can lead to many different mechanisms of death, any cause of death can have several different manners of death. A gunshot wound to the head can’t be a natural death, but it could be deemed homicidal, suicidal, or accidental.

MANNERS OF DEATH: For what purpose and by whose hand

NATURAL: Natural deaths are due to the workings of Mother Nature in that the death results from a natural disease process. Heart attacks, cancers, pneumonia, and strokes are common natural causes of death. This is by far the largest category of death that the ME sees. 

ACCIDENTAL: Accidental deaths result from an unplanned and unforeseeable sequence of events. Falls, automobile accidents, and in-home electrocutions are examples of accidental deaths. 

SUICIDAL: Suicides are deaths that come by the person’s own hand. Intentional self-inflicted gunshots, drug overdoses, or self-hangings are suicidal deaths. 

HOMICIDAL: Homicides are deaths that occur by the hand of another. Note that a homicide is not necessarily a murder. Homicide is a determination of the ME; murder is a legal charge that is determined by the courts. Though each would be ruled a homicide by the ME, the legal jeopardy is much different for a court verdict of negligent homicide as opposed to first- or second-degree murder. 

UNDETERMINED OR UNCLASSIFIED: This extra category is used in situations where the coroner can’t accurately determine the appropriate category. 

Examples:
Car/pedestrian
Heroin/Drug OD
GSW

Psychological Autopsy

Manner determines whether there is an investigation

Manner not fixed—can change
Proximate cause— the cascade of events

Coffin Birth: An Ancient Egyptian Mystery and the Solving of a Famous Case

Coffin Birth is a term used to describe the delivery of a baby postmortem. That is, the mother is dead and sometime later the child is expelled from the uterus. How does this happen?

During human decomposition, which begins almost immediately at death, the bacterial destruction of tissues leads to the formation of gas within the tissues as well as within the abdominal cavity. Most of the bacteria of decay reside within the G.I. tract so abdominal gas accumulation would be expected. As this accumulation progresses, the intra-abdominal pressure rises. If the victim is a pregnant woman, this pressure can collapse the uterus and force the fetus through the cervix, the vaginal canal, and out into the world. This is called a coffin birth. This can occur days or even weeks/months after death. The timing mostly depends on the speed of the decay process, which in turn depends on the ambient temperature.

Italian researchers have recently found a medieval grave that suggests exactly that. From the arrangement of the maternal bones and those of the near-term child, it appears a coffin birth may indeed have occurred.

Remember the famous Scott and Laci Peterson case? This is what happened to Laci and her unborn son.

Laci Peterson

Laci Peterson

Once the eight-month pregnant Laci was dumped into the San Francisco Bay, the decay process began. The coldness of the water caused a slowing of the decomposition so it took several months before enough gas accumulated to cause two important events that ultimately led to solving the case. First, her corpse became buoyant and floated to the surface and washed ashore, where it was found. The second is that a coffin birth occurred and her unborn child, Connor, was delivered and also washed ashore nearby. The location was near where Scott had said he had gone fishing on that Christmas Eve day. Locating the bodies placed him squarely at the disposal site. Gruesome and sad. Fortunately, Scott now resides in San Quentin.

Did “Tourista” Kill the Aztecs?

Many people who travel to other countries end up suffering from Tourista, or Traveler’s Diarrhea, a gastrointestinal upset that is manifested by diarrhea and sometimes nausea and vomiting. It’s due in many cases to E. coli, which is found everywhere. Various regions will have different strains of E. coli. Residents of the area are able to live quite compatibly with it. The problem arises when you travel to a new area and are exposed to a different strain. Until the body readjusts to this foreign strain, gastrointestinal symptoms can occur. Usually, this is mild and inconvenient and after a few days everything settles down and life goes on.

Tenochtitlan1

 

Not so with the Aztecs. In 1545, an epidemic swept through the Aztec nation killing millions, perhaps as much as 80% of the population. Twenty years earlier an epidemic of smallpox had come through and damaged the population and 20 years later another epidemic swept through killing another huge portion of the population. There have been many infectious processes indicted for the 1545 plague, which the Aztecs called cocoliztli. Smallpox, measles, mumps, and various other infectious entities have been blamed for this. But what if it was actually a gastrointestinal bacterium that did the damage?

The symptoms the victims suffered seem to have been gastrointestinal. Apparently, there was bleeding, vomiting, diarrhea, and splotches on the skin. These symptoms and signs suggest a form of enteritis and that’s exactly what the bacterium salmonella does.

New evidence suggests that it might be a strain of salmonella that caused this problem, in particular, salmonella Paratyphi C. Genetic research using DNA obtained from the teeth of those who succumbed to the epidemic indicate that this might be the case. Where it came from is another question. Did it come with the influx of Europeans? Or perhaps extend south from northern Mexico? This is still being debated and researched but it does appear that salmonella may have been the culprit in the epidemic that destroyed the Aztec Empire.

Salmonella has been responsible for other public health crises, one of the most famous being Mary Mallon, aka  Typhoid Mary. In this situation, the type of salmonella was salmonella typhi, which causes typhoid fever.

The Mystery of Chopin’s Heart

p01bqdpx

Did Frederic Chopin die from Tubercular Pericarditis? And what the heck is that anyway?

Pericarditis is an inflammation has occurred of the pericardium, the sac that contains the heart. Most often it is due to a viral infection but there are many others causes. One of the worst is tuberculosis (TB).

Tubercular Thickening of the Pericardium

X-Ray Showing Thickened Pericardium
(White ring around heart shadow)

Tuberculosis has wreaked havoc in humans for centuries. It has been found in Egyptian mummies and has devastated entire populations. Treatment didn’t appear until the 20th century and in recent years new, more malignant forms have appeared. Even after several millennia, it remains a difficult medical problem.

It attacks the lungs and slowly destroys the tissues, leading to cough, fatigue, weight loss, and muscle wasting—-the reason it was called “the consumption.” It, at times, literally consumed the sufferer.

When it spreads to the heart, particularly the pericardium, it can quickly become deadly. A thick viscous fluid collects in the pericardial sac, compresses the heart, and interferes with its function as a pump. This fluid can also solidify into a leathery trap around the heart so that even survivors of the initial infection can suffer severe, long-term problems that we term constrictive pericarditis—-the encasement restricts cardiac filling and thus effects pumping.

Recent studies suggest that this is what happened to Chopin. His heart took a strange and convoluted journey. He had requested that at his death that his heart be removed and returned to his native Warsaw, Poland. When he died in Paris in 1849, his heart was indeed removed, placed in a crystal jar, and encased in a stone pillar at the Holy Cross Church in Warsaw. In a recent examination, researchers found evidence that suggested he had suffered from TB pericarditis.

Burking Still Lives After 200 Years

Asphyxia is the interruption of oxygen (O2) supply to the body, particularly the brain. Normally, air contains O2 and, when breathed in, it passes into the blood, using hemoglobin as a transport molecule, where it is distributed to the tissues. Any interruption of this delivery chain can lead to death from asphyxia.

The air might be deficient in oxygen such as at high altitude or when another gas such as carbon dioxide (CO2) accumulates, depressing the O2 content to dangerous levels. Or flow into the mouth and nose could be restricted by smothering, choking, or strangulation, or by anything that restricts the expansion of the chest. Or the inhaled air could contain a toxin such as carbon monoxide (CO) or cyanide (CN), and these, in turn, interfere with O2 delivery to the tissues.

Burking is the term applied to asphyxial deaths that result from someone sitting on another in a fashion that restricts breathing. The victim dies from asphyxia. This is a form of Mechanical Asphyxia, where the movement of the chest wall is restricted to the point that breathing isn’t possible. Burking refers to the famous case of Burke and Hare.

From FORENSICS FOR DUMMIES:

Applying Pressure: Mechanical Asphyxia

Mechanical asphyxia results when some external force applied to the body prevents the expansion of the chest and leaves the victim unable to breathe. A person trapped beneath a heavy object, such as a car or a collapsed wall or ceiling, can die because the force of the external pressure prevents the victim from taking in a breath.

A boa constrictor kills in exactly this way. This muscular species of snake wraps itself around its prey. Each time the prey exhales, the snake coils a little tighter. So, each successive breath becomes increasingly shallower until the prey can’t take another breath. Death follows quickly.

Suffocation by “Burking” 

Experts have come to know a particular form of mechanical suffocation as Burking. William Burke was a merchant of sorts around Edinburgh, Scotland, in the early 1800s. In 1827, he hooked up with William Hare, who ran a beggars hotel in the village of Tanners Close. In December of that year, a resident of the hotel died, and Burke arranged to sell the body to a Dr. Knox, who needed corpses for his dissection demonstrations. Burke and Hare loaded a coffin with bark and buried it in front of many witnesses. They then delivered the body to Dr. Knox and received seven pounds and ten shillings. The men struck an arrangement whereby Burke and Hare would deliver the doctor more bodies for eight pounds in summer and ten in winter. (Apparently grave robbing was more difficult when the ground was cold.)

Burke and Hare began digging up fresh corpses for their new enterprise, but the local populace refused to die fast enough for the greedy men. They began kidnapping and killing people who were not likely to be missed. Burke sat on his victims, holding their mouths and noses closed until they suffocated, after which Burke and Hare delivered the corpse and collected their fee.

A lodger at the hotel notified authorities when she discovered the sixteenth and last victim beneath a bed. Police arrested the two men. Hare then cut a deal and testified against Burke. Burke was convicted and experienced asphyxia for himself when he was hanged on January 28, 1829, an event attended by as many as 40,000 people.

 

Burking is alive nearly 200 years later. It seems that 325-pound woman sat on her 9-year-old cousin to punish her for some indiscretion. Unfortunately, the child died from mechanical asphyxia—-“Burking.”
