Penetrating trauma can be caused by a foreign object or by fragments of a broken bone. Usually occurring in violent crime or armed combat, [3] penetrating injuries are commonly caused by gunshots and stabbings. [4] Penetrating trauma can be serious because it can damage internal organs and presents a risk of shock and infection.
While needlestick injuries have the potential to transmit bacteria, protozoa, viruses and prions, [6] the risk of contracting hepatitis B, hepatitis C, and HIV is the highest. [7] The World Health Organization estimated that in 2000, 66,000 hepatitis B, 16,000 hepatitis C, and 1,000 HIV infections were caused by needlestick injuries.
A gunshot wound (GSW) is a penetrating injury caused by a projectile (e.g. a bullet) shot from a gun (typically a firearm). [11] [12] Damage may include bleeding, bone fractures, organ damage, wound infection, and loss of the ability to move part of the body. [2]
Tetanus is caused by the tetanus bacterium, Clostridium tetani. [1] The disease is an international health problem, as C. tetani endospores are ubiquitous. Endospores can be introduced into the body through a puncture wound (penetrating trauma).
An injury is any physiological damage to living tissue [1] caused by immediate physical stress. Injuries to humans can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion.
While a primary infection can practically be viewed as the root cause of an individual's current health problem, a secondary infection is a sequela or complication of that root cause. For example, an infection due to a burn or penetrating trauma (the root cause) is a secondary infection. Primary pathogens often cause primary infection and often ...
Penetrating trauma, including iatrogenic causes such as joint replacements or internal fixation of fractures, leading to a fracture-related infection, [18] or secondary periapical periodontitis in teeth. [13] The area usually affected when the infection is contracted through the bloodstream is the metaphysis of the bone. [17]
A crabeater seal injured by a predator. Injury is physiological damage to the living tissue of any organism, whether in humans, in other animals, or in plants.. Injuries can be caused in many ways, including mechanically with penetration by sharp objects such as teeth or with blunt objects, by heat or cold, or by venoms and biotoxins.
