What are second and third
degree burns?
Lesions in which there is a complete necrosis (dead) of the epidermis (skin) over the entire target area. Also referred to as a “scald burn”
-
What distinguished between
a second and third degree burn?
The depth of the burn- 2nd is more surfaced and the 3rd burns down deep (muscles, nerves, and tissues) and will not come back so you will either have scar tissue or need a skin graft
-
What is meant by
threshold exposure
The shortest time at any given temp that causes complete destruction of the epidermis
-
Examples of Threshold
Exposure:
- 111 degrees is the lowest possible temp for subcutaneous burning and requires 6 hrs-that is, burning below the skin
- 115 degrees requires 3 hrs
- 118 degrees requires 15 minutes
- 155 degrees requires 1 sec or less
- Exposure to the sun can someone get a 2nd or 3rd
- degree burn? Yes
- 140 degrees is the temp at which hot water heaters are normally set
-
What does the body do to
compensate for excessive heat at the level of the epidermis?
Its going to start cooling it and your body will gradually get there unless it’s a very bad case
-
What is hyperthermia?
Excessive heat
-
What is hypothermia?
Excessive cold
-
According to Monteleone,
what is the most common place that burn
Injuries were recorded?
home
-
The most common type of
burn
- (48% rounded) were scald
- burns,
- followed by flame (30%
- rounded)
-
What is a stocking burn?
- About the same as a glove
- burn
-
A glove burn?
- Immersion-Its an even
- pattern at the bottom, some splashing at the top
-
abusers tend to target the
area for abuse
that’s the cause of the problem
-
most commonly identified explanation (trigger mechanism) for burn injuries due to abuse is
toilet training
-
Reference to Alfred Hitchcock movie—significance of the movie scene
- Killing Someone Is Not Easy
- Tom Curtain, 1966-Kills a man in a hotel roomtook about 5 mins
-
Reference to police
training—being shot
early training they were told to shot twice but now they are taught to empty the gun
- ○ Societal expectations when someone is shot
- ○ Societal expectations when someone else is shot
-
Reference to Sherwin Nuland’s book How We Die.
the physiological processes of dying from a number of diseases,accidents, homicides, and etc
-
Drowning is a form of
asphyxia
○ The mouth and nostrils are occluded by water
-
Step 1 in drowning
- The mouth and nostrils are occluded by water
-
-
Suicide By Drowning
Generally will not resist the inhalation of water
-
Step 2--If
accidental—or someone intentionally tries to drown someone—the victim will..
- victim will fight by holding his breath until becoming too exhausted
- and hypercarbic to continue. Hypercarbic-depletion of oxygen in the
- blood
-
Step 3 in drowning
- Obstruction
- ○ The air passages then become obstructed—all the way down to the lungs
- ○ Note: near the surface there is the possibility of foaming from the mouth and a vomiting reflex
-
Key
question—the aspiration of water is delayed at first—WHY?
Itis one of the body’s natural reflex mechanisms.
-
how long does this last ( how long it take to drown?)
About 2-3 minutes. When the water first hits the airways-the larynx reflexively goes into spasm and closes off in an effort to present further intake
-
Step 4—what
happens that causes it to relax?
Decreasing oxygen in the blood and causes the larynx to relax
-
Step 5—then what
happens?
The water rushes into the lungs and fills them after about 5 mins
-
Is the person dead if they have been drowning ?
It depends, but you can always try to save them
-
What
happens in fresh water drowning?
- The water is absorbed into the circulation through the lungs, the blood is diluted; the chemical imbalance is upset resulting in disequilibrium in the blood; red blood cells are destroyed; large amounts of potassium
- are released into the circulation system and a cardiac poison that causes the heart to fibillate
-
WHAT
HAPPENS IN SALT WATER DROWNING?
- The process is reversed—
- water leaves the circulation and enters the aviola of the lungs
- The same process as dying from pneumonia
-
What form of drowning would you expect
to find in a swimming pool?
Why?
Salt water drowning b/c of the chlorine
-
Does
body mass play a role in drowning?
- Yes, adipose tissue releases fat- fat is bouyant
- ○ Think of children—especially babies—and fatty tissue ratio
- ○ 10% of Caucasians and Hispanics are natural “sinkers”
- ○ 90% of Blacks are natural “sinkers”
-
Think of the movies—how do they portray a drowning victim once the body begins to sink?
Is the body “dead”?
On their side, feet first
no
-
What is the significance of this knowledge for investigation of a drowning?
Are there exceptions?
For example, injuries to the head (cuts, abrasions, etc. may appear to have been inflicted prior to the drowning
- Yes, about 15% of drowning victims are the result of “dry drowning”
- ○ There may be no water in the lungs
- ○ And, of course, the position of drowning victims may vary depending on circumstances
-
How does the corpse of a drowning victim sink? In what position would you expect to find the body of a drowning victim?
Are there exceptions?
Head first. The head will looked scratched/cut and beat
Yes, about 15 % of drowning victims are the result of “dry drowning”

Shaken Baby Syndrome
defined
is a type of inflicted traumatic brain injury that happens when a baby is violently shaken. (National Institute of Neurological Disorders and Stroke
-
What is the primary
trigger mechanism for Shaken Baby Syndrome?
crying
-
Focal is..
when a spot hits something in contact but diffuse is through the brain
-
(Earthquake vs. Peak
Acceleration)
- Earthquake-slow moving back and forth.
- Peak is rapid movement with abrupt stop
-
Shaken baby is the result
of a
Repeated peak acceleration action
-
Seven physiological
aspects of shaken baby syndrome
- (1) Bridging veins
- (2) Subdural hematoma and bilateral subdural hemotama
- (3) Concussions
- (4) Shearing of brain tissue
- (5) The eye
- Detached retina
- Retinal hemorrhaging
- (6) Fracture Rib head, first rib, clavicle, and other bones
- (7) Diffuse axonal injury
-
The coverings of the brain-in order from top to bottom
- a. skin-hair on top
- b. skull-blood vessels on top
- c. Dura Mater-subdural hematomas are right below this
- d. Arachnoid
- e. Pia Mater
- f. the brain
-
What is a concussion?
Bruising of the brain tissue
-
a concussion reduces
normal flow of oxygen to the part of the brain
-
Normally, a single concussion...
doesn’t deplete all of the oxygen flow and, in time, the flow of oxygen returns to normal with no serious damage
-
Repeated concussions in Short intervals result in
additional oxygen deletion with successive concussions resulting in depletion of oxygen (ischemia) to the point that the brain matter cannot recover and necrosis (death) occurs.
-
Shearing of arteries
Most likely to result form Peak acceleration-deceleration forces
when the brain is moving within the skull cavity
-
Peak acceleration- deceleration causes what happens to the arteries (and nerves) in the brain?
Bending and stretching the brain also slams against the wall of the skull
-
Results of Peak acceleration-deceleration
contusions/concussions but can also result in tearing of arteries
-
Focal Injuries and
possible results
a direct blow to the head can also result in rupturing and shearing of the arteries within the brain and the veins in the dura cavity
-
Clavicle
the rib that’s going to break first is going to be in the front

-
Pedophilia
- is a medical term-- “The act or fantasy or engaging in sexual activity with pre-pubertal children as a repeatedly
- preferred or exclusive method of achieving sexual excitement.”
-
Hebephile
The same definition as pedophilia, except the child has reached puberty.
-
Child Molester
“A significantly older individual who engages in any type of sexual activity with individuals legally defined as children"
-
Munchausen Syndrome By Proxy defined
A form of child abuse in which a parent or guardian fabricates or induces illness in a child.
-
Who is the most common perpetrator?
(MSBP)
the mother
-
Why is Munchausen Syndrome
By Proxy so difficult to diagnose?
The caretakers of the children are adept at deceiving medical and mental health professionals
-
Most common form of MSBP
Apnea
-
Some reasons (5) that make MSBP difficult to prove
- 1. The evidence is usually circumstantial.
- 2. Physicians are not trained to identify.
- 3. Physicians are uncomfortable with the concept of MSBP.
- 4.Judges are reluctant to believe that the condition exists.
- 5. Juries do not want to believe that mothers
- would do such a thing
-
Five General Facts to Consider with MSBP
- 1. Perpetrators who engage in MSBP are often connected, or have been connected to, the medical profession or child care agencies
- 2. The perpetrators research medical symptoms and conditions. They know what they are talking about
- 3. Shopping--perpetrators move around from doctor to doctor, hospital to hospital.
- 4. The children are often coached and become very good at faking and are convincing
- 5. Mortality rates are estimated at about 10 %.
-
what 2 types of monitoring did the hospital study from the MSBP lecture use
video and voice
-
Research Procedures of hospital study on MSBP
- 1.Multidisciplinary team worked together at a hospital
- 2. Emphasis on protecting the child
- 3. When a child was admitted the family member signed a form. Included was permission to use video and sound monitoring
- 4. Security officers monitored the surveillance cameras 24 hours a day.
- 5. If something observed, the floor nurse was notified and immediately went to the room and intervened.
- 6. Most of the cases were referred to this hospital because of the video surveillance and because a physician suspected MSBP.
- 7. A team at the hospital decided that there was a high probability this was a case of MSBP before monitoring.
-
were the family member in the hospital room (in the MSBP study ) monitored
yes
-
Two types of perpetrators of MSBP
- 1. Inducers induce the disease or medical condition
- directly.{(Note example given: smothering 1injection of bodily fluid (urine)}
2. Fabricators No inducement of disease or medical condition.--Either creates symptoms by lying or stages the disease. (Note example given: mother vomits and then presents the vomit as coming from the child)
-
chief medical complaints if children admitted to the hospital...
- 1.Apnea/cyanosis
- 2.Undiagnosed persistent symptoms
- 3.Vomiting
- 4.Sepsis
- 5. Behavior problems
- 6. Other
-
Coaching MSBP
Some of the mothers were overheard coaching their child to display the symptoms.
-
41 cases were monitored at the hospital how many were confirmed as MSBP? and what types?
- 23 confirmed
- 10 fabricators
- 2 inducers
- 11 both
- § 2 of these confirmed by lab drug tests
- § 2 by direct observation
- § 1 confessed when questioned
- ○23 cases confirmed
- ○13 required video monitoring to prove
- ○5 the video monitoring was supportive
- ○5 video monitoring was not necessary
-
All of the perpetrators of the confirmed cases of MSBP
were what type of caregiver to the child?
the mother of the child
-
Monitoring resulted in how many of the 41 suspected perpetrators being proved innocent?
4
-
What across the counter medicine is frequently used to induce vomiting by MSBP perpetrators?
epicac
-
Many perpetrators use MSBP as a way of
gaining social attention and social acceptance
-
Can fabricating a child’s illness ever be considered a crime?
yes
-
What singer produced a well known song about his own experience with MSBP?
Eminem
-
What is the current medical theory as to why repeated concussions to the same place on the brain, in short
successive periods, results in permanent loss of the brain matter?
- A concussion reduces the normal flow of oxygen to that part of the brain. Normally, a single concussion does not deplete all of the oxygen flow and, in time, the flow of oxygen returns to normal with no serious
- damage. Repeated concussions in short intervals results in additional oxygen depletion with eachsuccessive concussion resulting in depletion of oxygen (ischemia) to the point that the brain matter
- cannot recover and necrosis occurs.
-
What is the physiological mechanism by
which the concussed area is deprived of oxygen.
- During a concussion, arteries constrict, slowing blood flow to the brain. At the same time, calcium floods the energy-producing portions of brain cells. That calcium
- plays a mean defense, blocking oxygen- and glucose-rich blood from replenishing neurons' energy supply.
-
If the area of the brain what has suffered a concussion is not allowed sufficient time to heal, what happens when there is a second concussion to the same area?
- The constriction of arteries increases and additional calcium floods the energy-producing portions of brain
- cells. The flow of oxygen is further depleted and may be reduced completely or sufficiently to the point that cells in this part of the brain die. Remember, necrotic brain cells are not replaced by new brain cells.
-
Why is playing sports with concussion symptoms so risky?
During a concussion, arteries constrict, slowing blood flow to the brain. At the same time, calcium floods the energy-producing portions of brain cells. That calcium plays a mean defense, blocking oxygen- and glucose-rich blood from replenishing neurons' energy supply. Brain cells get sluggish, and a concussed athlete who can't focus or suffers from slower reaction times is left more susceptible to a slew of other injuries, including another concussion. A second blow to the head could lead to more arterial constriction and more calcium infusions.
