Superficial
Circumscribed extravasation of blood in the subcutaneous tissue or underneath the mucus membrane
Petechiae
Incomplete or partial dislocation
Subluxation
Direction of wound in suicidal cut throaut
Oblique
Aka linear fracture
Fissure fracture
Caused by impact of a blunt object and may appear as a radiating crack from the site of application of force and may involvr the base of the cranail fodda
Fissure fracture
Aka fracturrs la signature
Localized depressed fracture
Common in the skull of infants wherein there is undue elasticity
Pond or indented fracture
Tangential or glancing approach of a bullet may cause what fracture
Gutter
A person is exempted from criminal liability if he os totally deprived of his understandig and memory and knows no more than an infant, a brute, or a wild beast of what he is doing
Wild beast rule
IC hemorrhage caused by a fracture in the skull
Extradural or epidural
IC where branches of meningral vessels are most often involved
Extradural/ epidural
Most common cause of cerebral compression
Subdural
Secondary kidney changes in crush injuries. Edema and anuria follow a crush. If death supervenes, the kidneys are found to be swollen, pale with marked degeneration of the cells lining the tubles
Crush syndrome
Classification of explosion: occurs when the pressure inside the container exceeds its structural strength
Mechanical(hydraulic)
Can be regarded as condensed energy
Atomic explosion
Release of significant amount of energy by fusion or fission
Nuclear
Explosion caused by mixture of gas and air
Diffused reactant explosion
Occurs when a large quantity of heat and gas is produced as a result of rapid chemical reaction in a solid or liquid material
Condensed reactant explosiob
Deflagrating explosive; rely on burning and confinement to produce explosiob
Low order explosive
Kind of explosive that detonates
High order explosive
Triad of punctate bruises, abrasion, and lacerations may be found distributed all over the body
Not so close to site of explosion
Most destructive nuclear rays
Gamma and neutron
Injury is caused by the missile propelled by the explosion of the gunpowder located in the cartridge shell at the rear of the missile
Firearm shot
Primary propulsive force in a cartridge
Gunpoweder
Sudden release of expanded gas from the muzzle following the bullet
Muzzle blast
Presence of smudging of the wound of entrance infere
A near shot
Responsible for the production of tattoong
Powder grains
Blackening of the margin of the gunshot wound entrance
Powder burns
Bullet travelling in a liquid or solid media accelerates or decelerates transmission of force?
Accelerates
Shape gunshot wound where bone is superficial
Star
Shape gunshot wound where bone is deeply located
Circukar
Metal fouling: superficial or deep bone
Superficial
Medium range is a range of?
15-60 cm
At what range can these finding be found? muzzle imprint, blackening of bullet, and carboxyhemoglobin
Near fire
At what range can tattoing and contact ring be found?
1-15cm ;15-60cm (short and medium range)
At what range are the following not found? Abrasion color, smudging
> 60 cm
At what range is the diameter of the gunshot wound almost the same as the caliber?
Distant fire
If the place where the gunshot wound of exit is pressed on a hard object as when the victim is lying on his back on a hard object, the wound exit tends to be circular or nearly circular with abrasion at its norder
Shored gunshot wound of exit
Bullet loses its momentum while inside the chamber of the heart or inside the big blood vessels
Bullet embolism
Contact or near contact in shotguns is approximately
<6 inches
Test for presence of powder residues on the skin
Dermal nitrate test(paraffin, diphenylamine test, lung’s test, gonzales test)
Test for presence of powder residues on clothing
Walker’s test (dark res or orange brown spots)
Test for presence of primer components: yields blue-violet color in the presence of lead while bright pink color is developed in the presence of barium
Harrison and Milroy test
Test for presence of primer components: a sample is obtained from the hands by the use of paraffin and then exposed to radiation. Extremely sensitive
Neutron activation analysis
Test for presence of primer components: Quick sensitive and empolys equipment within economic means. It can detect presence of barium, antimony and lead
Flameless atomic absorption spectroscopy
Most specific bu seldom used because it is expensive and it requires longer period of time to analyze a case
Scanning electron microscope with a linked x ray analyzer
Aka miner’s cramps, fireman’s cramp, stoker’s cramp
Heat cramps
Involuntary spasmodic painful contraction of muscles essentially due to DHN and excessive loss of chlorides by sweating
Heat cramps
Heart failure primarily caused by heat and precipitated by muscular exertion and warm clothing
Heat exhaustiob
Aka heat hyperexia, comatous form, thermic fever
Heat stroke
Classification of burns by degree
Dupuytren’s classification
Dupuytren’s classification: erythema or simple redness of the skin associated with superficial inflammation and alight swelling
1st degree
Dupuytren’s classification: vesicle formation with acute inflammation
2nd degree
Dupuytren’s classification: burned area is very painful; destruction of the cuticle and parr of the true skin
3rd degree
Dupuytren’s classification: whole skin is destroyed with formation of slough which is yellowish brown or parchment like
4th degree
Dupuytren’s classification: invlolvement of deep fascia and muscles
5th degrew
Dupuytren’s classification: charring of the limb involving subjacent tissues, organs and bone
6th degree
Extent of surface involvement that leads to fatality
1/3 (second and third degree burns)
No pus, or much healing or edema : Age of Burn?
Recent
(+) pus and the red inflammatory zone has disappeared: Age of Burn?
36 hrs to few days
(+) superficial sloughing in a 3rd degree burn:Age of Burn?
1 weeks
Deeper sloughs and are attended with supparation; (+) res granulation
2 weeks
Blisters of ante mortem burns contain what
Abundant albumin and chloride
Splitting of the soft tissue of the body, like the skin due to exposure before or after death of the body to considerable heat
Heat rapture
Heat coagulates albuminous materials inside the muscles making it stiff and contracted
