if you can say due to
haven't gotten to cause of death
27
HIV patient
lymphoma > infection > death cause of death - AIDs mechanism of death - septic shock
28
AIDs
can be cause of death
29
wounds from blunt force
abrasion contusion laceration
30
skull of children
harder to fracture | -so you know there is lots of force
31
velocity
more important than mass | -fast small bullet more damaging than slow large bullet
32
contusion severity
``` force vascularity type of tissue location of tissue bruisability ```
33
yellow bruise
presence indicates bruise is 18 hours or older** blue, purple, red don't assist in dating bruise brown is mix of colors
34
abrasion
damaged epidermis friction scraping away epidermis oozes serum or blood gliding - can be bad - ex. motorcycle accident
35
gliding abrasion
force is tangential to body surface | -rolls or heaps of tissue at wound margin
36
patterned abrasion
can be useful in forensics abrasion recapitulate the surface appearance of the instrument
37
dicing injuries in vehicle accidents
windshield are different than passenger windows passenger window - dicing injuries
38
stab wound
sharp force injury where depth is greater than length of wound deeper than longer knives, scissors, screwdrivers, etc.
39
ice pick under skull
unmistakable when you look at autopsy
40
civilian knives
single edged should have blunt squared off side
41
military knives
double edged
42
overkill
means this was something personal often - to face
43
high velocity
exit larger than entrance
44
low velocity
exit and entrance similar size
45
shored
bullet restricted from exiting exit looks like entry
46
head shots
sharp outer table beveled inner table opposite for exit wound
47
suicide
often contact range gunshot
48
hot enough brain
head will explode
49
macro at crime scene
survey, document, safeguard live persons first
50
micro at crime scene
bio materals, specimin retrieval
51
civilian knife
blunt side
52
military knife
two sharp cutting edges
53
cuts only on bony prominences
likely a fall
54
algor mortis
cooling of body
55
rigor mortis
stiff
56
livor mortis
blood sinks to lower parts of body
57
mummification
dry climates
58
adipocere formation
body in water for a long time | -skin erodes - fat covers body
59
increasing drug resistance
bacteria, rickettsia, and viruses are 80% of emerging infectious diseases
60
common infection after burn
pseudomonas aeruginosa
61
intermediate gun shot wound
not likely a suicide think homicide
62
tardieu spots
subdural or pleural petchiae individuals who have been strangled
63
US homicide
highest in males 15-34
64
putrefactive decomposition
GI bacteria cause putrefaction of body wall | -RLQ - cecum first
65
ischemic brain with CO poison
basal ganglia
66
mercury detox
intracellular glutathione
67
vinyl chloride
angiosarcoma of liver
68
bleomycin
interstitial fibrosis of lung chronic effect*
69
radiation complication
aplastic anemia acute effect*
70
thimerosol
in vaccines -thought to cause autism probably wrong
71
cause of death
myocardial infarction
72
mechanism of death
cardiac arrhythmia
73
ecognine
metabolite of cocaine
74
eading cause of death in infants 1 month to 1 year
SIDS yes legitimate COD
75
most common morph finding in child dying of SIDS
astrogliosis in brain stem
76
subsequent SIDS sibling
increased risk
77
most common tumor of infancy
hemangioma
78
sudden death in child less than 1 year not due to SIDS likely
infection
79
teratoma before 4 months
likely benign
80
blasts in peripheral blood
never normal | -likely B cell ALL
81
severe classes of CF
1, 2, 3
82
smoker
cardiac arrhythmia | -decreases threshold for ventricular fib
