The Intersection of Medicine and Forensic Toxicology

Introduction

Medicine and forensic toxicology are two closely related fields that intersect in the investigation of crimes, accidents, and other incidents involving toxic substances. Forensic toxicology plays a crucial role in determining the presence and effects of drugs, chemicals, and poisons in biological samples. This article explores the connection between medicine and forensic toxicology, highlighting their collaborative efforts in promoting public safety and justice.

Medicine’s Role in Forensic Toxicology

Medicine provides the foundation for forensic toxicology by studying the effects of substances on the human body. Medical knowledge and expertise help forensic toxicologists understand the pharmacokinetics and pharmacodynamics of drugs, the physiological impact of toxins, and the interactions between substances and bodily systems. Medical professionals, such as pathologists and forensic physicians, often collaborate with forensic toxicologists to analyze toxicological findings and interpret their significance.

Forensic Toxicology in Criminal Investigations

Forensic toxicology plays a vital role in criminal investigations by identifying and quantifying toxic substances in various samples, including blood, urine, hair, and tissue. Toxicologists utilize sophisticated analytical techniques, such as gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS), to detect and measure drugs, poisons, and their metabolites. This information can provide crucial evidence in cases involving drug overdoses, driving under the influence (DUI), poisoning, and suspicious deaths.

Medicolegal Autopsies

Medicolegal autopsies, performed by forensic pathologists, combine medical examination with toxicological analysis to determine the cause and manner of death. Toxicologists assist in the autopsy process by collecting samples, analyzing bodily fluids and tissues for toxic substances, and interpreting toxicological findings. This collaboration helps establish a comprehensive understanding of the circumstances surrounding the individual’s death, particularly if it is related to drug toxicity, poisoning, or chemical exposure.

Medication Monitoring and Drug Testing

Forensic toxicology plays a significant role in medication monitoring and drug testing programs. In various contexts, such as workplace drug testing or probation monitoring, toxicologists analyze biological samples to detect the presence of illicit drugs or misuse of prescribed medications. These tests can provide objective evidence of drug use, aiding in treatment programs and legal proceedings and ensuring public safety.

Expert Testimony in Legal Proceedings

Forensic toxicologists often serve as expert witnesses in legal proceedings, providing objective and scientifically sound testimony related to toxicological findings. Their expertise is crucial in explaining the effects of drugs or poisons on the human body, interpreting laboratory results, and assisting the court in making informed decisions.

Conclusion

The collaboration between medicine and forensic toxicology plays a crucial role in investigating and understanding the effects of toxic substances on human health and in the legal system. Through their combined efforts, medical professionals and forensic toxicologists contribute to public safety, assist in criminal investigations, and provide expert guidance in legal proceedings. The intersection of medicine and forensic toxicology highlights the importance of a multidisciplinary approach to understanding and addressing issues related to toxic substances in society.

Why Are Girls Reaching Puberty Earlier? via The DALE YEAGER Blog

Diet, Endocrine Disruptors, and the COVID-19 Pandemic are documented in this article.stealing years away from the childhood of young girls

An article by Martha Rosenberg explains the four factors which are directly correlated to early puberty in girls. Three of these: Diet, Endocrine Disruptors, and the COVID-19 Pandemic are documented in this article. But the one I want to focus on is Anxiety and Stress Within the Family. Dale Yeager

The age at which girls are reaching puberty is steadily falling. In 1840, the average girl was 16.5 years when she attained menarche—the onset of menstruation. By 1920, the age had dropped to 14.6; by 1950, it was 13.1; in 1980, 12.5; and 12.43 in 2020. By 2022, the percentage of U.S. girls who reached menarche by age 10 had risen to 10 percent from 7 percent.

By 2010, the average girl reached puberty at the age of 10.5. Not only is the drop in puberty age seen across race/ethnicity groups in the United States, but according to a study in the Journal of Adolescent Health, the same trend toward early puberty has also been reported in England, Israel, China, India, Korea, Ghana, Mexico, and Thailand.

There are many reasons why early onset puberty, also called precocious puberty, matters. Early puberty puts girls at increased risk of obesity, diabetes, heart disease and other cardiovascular diseases, low bone mineral density, gynecological/obstetric, gastrointestinal, musculoskeletal, neuro-cognitive, psychiatric and respiratory disorders, and cancer, according to medical papers. Children with precocious puberty “often stop growing earlier than usual” which can “cause them to be shorter than average as adults,” adds the Mayo clinic. Other scientific publications agree.

There are also psychological ramifications associated with early menarche. “Among adolescent girls, early puberty is associated with more depressive disorders, substance use disorders, eating disorders and disruptive behavior disorders,” according to an American Psychological Association article. Girls are also at increased risk of sexually transmitted diseases.

What Are the Causes of Early Puberty?

Most, if not all, medical professionals agree that the age of menarche is lowering but agreement ends there. There are many theories about the dramatic appearance of early puberty among so many girls, and it’s likely that many of them have a basis in fact and that more than one theory is accurate.

Diet

Research published in 2018 in the International Journal of Endocrinology that focused on a cohort of Chinese girls identified clear links between early puberty and diet.

An “unhealthy diet pattern, heavy in desserts and snacks, soft drinks, and fried food, was found to be significantly positively associated with precocious puberty in both boys and girls,” wrote the authors.

“This diet was implicated in the timing of puberty, probably in any of the three ways: high fat intake, high sugar, and obesity due to high-calorie consumption. Consumption of junk food, such as fried foods, had been convincingly linked to obesity and rapid weight gain, a potential predictor of earlier age at menarche and other markers of puberty.”

Certainly, the so-called Western diet has infiltrated countries that once observed local and traditional cuisines.

According to Dr. Robert Lustig, a professor of clinical pediatrics at the University of California–San Francisco’s Benioff Children’s Hospital, “Fatter girls have higher levels of the hormone leptin, which can lead to early puberty, which leads to higher estrogen levels, which leads to greater insulin resistance, causing girls to have yet more fat tissue, more leptin and more estrogen, the cycle feeding on itself, until their bodies physically mature.”

Endocrine Disruptors

Endocrine disruptors are chemicals that mimic and disrupt our hormone functioning and seem to lurk everywhere: in our food packaging, furniture, cleaning products, building materials, drinking water, gardens, cosmetics, and more. How badly have these unwanted chemicals invaded our world? Bisphenol A, a major endocrine disruptor often called BPA, was found in 90 percent of newborn infants tested by the Environmental Working Group along with more than 230 other chemicals!

Sadly, endocrine disruptors aren’t the only likely environmental culprits when it comes to tracing the roots of early puberty. Research published in the International Journal of Environmental Research and Public Health also associates metals such as manganese and lead “with the deregulation of the neuroendocrine system, which could potentially favor the appearance of precocious puberty in environmentally exposed children.”

Anxiety and Stress Within the Family

Research published in the journal Emergency Medicine International finds that the role of anxiety in the family system can contribute to early puberty. Girls with early puberty came from poorer households that were characterized by divorces and remarriages, according to the research. Girls whose parents divorced when they were between 3 and 8 years old were at greater risk. Father absenteeism is increasingly seen as a factor in girls who develop early puberty, say scientific papers.

“The absence of a biologically-related father has been shown to accelerate reproductive development,” write authors in the Journal of Adolescent Health. Two decades ago, researchers posited that “when girls encountered familial conditions that were unfavorable for survival (e.g., insecure and unsupportive family relationships), it was adaptive to become reproductively mature earlier. Since then, numerous empirical studies have confirmed that father absence predicts earlier maturation. Girls in father-absent homes are about twice as likely to experience menarche prior to age 12.”

The COVID-19 Pandemic

With its stress, forced isolation, the dominance of electronic communication, and negative effects on sleep and diet, the COVID-19 pandemic increased the occurrence of early puberty.

According to research in the Italian Journal of Pediatrics, “Due to lengthy periods of school closure, restrictions on activities, and changes in diet and sleep patterns, an increase in the frequency of obesity in children is to be expected,” wrote the authors.

“During the lock-down, children were not only out of school, but they also faced severe restrictions to their daily physical routines, and in this period of inactivity, it was inevitable that there would be an increase in screen-time. When all these contributing factors are combined, it is not difficult to predict that the situation could cause rapid weight gain.”

Sure enough, wrote the authors, “the onset of puberty was earlier in the pandemic period compared to the previous year.”

A similar phenomenon of increased early puberty was noted during the pandemic in Korea and in India.

Experts Weigh In

Dr. Jeanne Stolzer, a professor of child and adolescent development at the University of Nebraska, shared her thoughts with The Epoch Times. “I believe the early puberty we are witnessing is probably due to a convergence of variables.  However, I think that researchers need to be looking into two key variables: Screen use and COVID vaccinations. I also believe that lack of sunlight and physical activity may be contributing factors.”

“Although the multifarious effects of melatonin on the human gonadal system are not fully understood at this time, we do know that screen use clearly impacts melatonin levels,” she said. “Data indicates that melatonin affects oxytocin, vasopressin, and a plethora of growth hormones, therefore, early puberty may very well be related to increasing screen time as screen time disrupts the production of melatonin.”

Researchers also need to be looking into the correlation between vaccines and early puberty, observes Stolzer, “as preliminary data suggests that menstrual cycles have been adversely affected by the COVID vaccine. It stands to reason that age of puberty may also be impacted.”

One study, published in the International Journal of Clinical Practice in October, concluded that “COVID-19 infection and vaccination can affect the menstrual cycle in women.”

In a recent paper published in the International Journal of Sociology of the Family, Stolzer wrote, “Despite the scientific data demonstrating the plethora of negative effects associated with screen time, use of screens is increasing exponentially across the globe due in part to the world-wide pandemic.”

Yet, Stolzer laments, “As mounting scientific evidence continues to be published across continents confirming the negative effects associated with screen time, schools – from preschools to universities-are documenting significant increases in student screen time use.”

Stolzer said children “require large amounts of direct sunlight and rigorous outdoor physical activity if optimal development is to occur. As a direct result of the pandemic, access to the outdoors was severely limited in many communities thus hindering developmental processes exponentially.”

Big Pharma Creates Public School Vaccine Petri Dish in Temecula, CA

Local school districts around the country are under the thumb of vaccine pushing state laws which are financed and pushed by Big Pharma to expand the list of mandatory shots thereby creating a sick disease ridden population. The latest example is from the Temecula Valley school district that scares parents into thinking that it’s the law to inject toxic substances, live viruses, and animal DNA into your body. The neglect to mention that the exemption forms that exist in all but two states in the union. Read the damn insert and educate yourself before you inject yourself.

INFOWARS HEALTH – START GETTING HEALTHY BEFORE IT’S TOO LATE – http://www.infowarshealth.com/

Atascadero woman finds out she could be exposed to Hepatitis B, C & HIV

It has been several days since hundreds of letters from the Santa Barbara County health Department were mailed to patients of a local clinic.  Those letters warn patients to get tested for Hepatitis B, C, and HIV. 

“It’s the accident that just keeps on giving,” says Teresa Turner, a resident of Atascadero.

In 2011, 55-year old Turner says a drunk driver crashed into her, sending her to Dr. Allen Thomashefsky’s Santa Barbara Medical Clinic.

“Dr. Thomashefsky is a very friendly person, he seems to be a good guy,” says Turner.  “The office was very clean and there was nothing out of the ordinary.”

At his office, Turner says she underwent therapy.

“Neck, back, and abdominal muscle,” says Turner.  “I had several injections.”

When say this week’s news, a familiar face came up.

“It was announcing who the doctor was and it was Dr. Thomashefsky,” says Turner.

A phone call later to the Santa Barbara County Health Department, Turner was told she needs to get tested for possible Hepatitis B, C, and HIV.  An appointment that could not come soon enough.

“Monday although it is only a couple of days away, it seems like it is very far away,” says Turner.  “They are infectious diseases and I am concerned that they could have been shared with someone else.”

Turner says she knows the test results could be life changing.

 

“If I was to be infected by one of those, you feel like you are kind of labeled with a virus, how are people going to treat you,” says Turner.

 

She has made an appointment with her doctor in Paso Robles and hopes her story will help others take the necessary steps to move on.

 

“Because you don’t want to hide from this,” says Turner.  “It is a very important and serious issue and you have to go on that path and deal with it.”

Psychologists in focus; Kevin Dutton: Psychopath Studies

Video: PSYCHOLOGISTS IN FOCUS; KEVIN DUTTON

Dutton takes the view that we often miss what should be the obvious anomaly sidelined by the charm – But is it all smoke and fingers?

Kevin Dutton is a postdoctoral researcher at the University of Oxford.  He is specialises in the study of Psychopaths, but rather than the traditional forensic route Dutton takes interest how the ‘symptoms’ of psychopathy can have an advantage in a modern world that is fraught with stressors.  The psychopath often described as  having a selection of specific traits such as cunning and manipulativeness, lack of remorse or guilt, callousness and lack of empathy, charm, grandiose estimation of self, need for stimulation and pathological lying.  Not the best characteristics to put on a C.V.  It is included in the DSM under the classification of Antisocial Personality Disorder.   However in his book The Wisdom of Psychopaths Dutton discusses how these traits are rewarded in society particularly as resistance to stress where others feel the pressure, psychopaths are able to thrive. Self doubt and fear can impair decision making, the psychopath is arguably resistant to this –but would you want one as your boss?  Dutton is clear that this is far from the glorification of violent psychopaths (stating only a small minority of psychopaths are violent) rather acknowledging that the ‘spectrum of psychopathy‘ which all people can be measured and the right characteristics in the right circumstances can be a force for good – hence his term ‘the good psychopath‘.

Here is a quote from Dutton’s book the Wisdom of  Psychopaths, from James Geraghty cited as one of the UK’s leading neurosurgeons.

I have no compassion for those whom I operate on. That is a luxury I simply cannot afford. In the theatre I am reborn: as a cold, heartless machine, totally at one with scalpel, drill and saw. When you’re cutting loose and cheating death high above the snowline of the brain, feelings aren’t fit for purpose. Emotion is entropy, and seriously bad for business. I’ve hunted it down to extinction over the years.”

Do we need people like this in such high stakes roles where emotion maybe a hindrance rather than a help?  Or is compassion an essential characteristic that allows a surgeon to consider the long term impact of their work?

In fact jobs that Psychopaths are believed to flourish in are;

2. Lawyer
3. Media (Television/Radio)
4. Salesperson
5. Surgeon
6. Journalist
7. Police officer
