Wound
A wound is a rapid onset of injury that involves laceration, lacerated or puncture wound, punctured skin (an ''open'' wound), or a bruise, contusion (a ''closed'' wound) from blunt force physical trauma, trauma or compression. In pathology, a ''wound'' is an acute injury that damages the epidermis of the skin. To healing, heal a wound, the body undertakes a series of actions collectively known as the wound healing process. Classification According to level of contamination, a wound can be classified as: * Clean wound – made under sterile conditions where there are no organisms present, and the skin is likely to heal without complications. * Contaminated wound – usually resulting from accidental injury; there are pathogenic organisms and foreign bodies in the wound. * Infected wound – the wound has pathogenic organisms present and multiplying, exhibiting clinical signs of infection (yellow appearance, soreness, redness, oozing pus). * Colonized wound – a chronic situation, ...

Wound Healing
Wound healing refers to a living organism's replacement of destroyed or damaged tissue by newly produced tissue. In undamaged skin, the epidermis (surface, epithelial layer) and dermis (deeper, connective layer) form a protective barrier against the external environment. When the barrier is broken, a regulated sequence of biochemical events is set into motion to repair the damage. This process is divided into predictable phases: blood clotting (hemostasis), inflammation, tissue growth ( cell proliferation), and tissue remodeling (maturation and cell differentiation). Blood clotting may be considered to be part of the inflammation stage instead of a separate stage. The wound healing process is not only complex but fragile, and it is susceptible to interruption or failure leading to the formation of non-healing chronic wounds. Factors that contribute to non-healing chronic wounds are diabetes, venous or arterial disease, infection, and metabolic deficiencies of old age.Enoch, S ...

Ballistic Trauma
A gunshot wound (GSW) is a penetrating injury caused by a projectile (e.g. a bullet) from a gun (typically firearm or air gun). Damages may include bleeding, bone fractures, organ damage, wound infection, loss of the ability to move part of the body and, in more severe cases, death. Damage depends on the part of the body hit, the path the bullet follows through the body, and the type and speed of the bullet. Long-term complications can include lead poisoning and post-traumatic stress disorder (PTSD). Factors that determine rates of gun violence vary by country. These factors may include the illegal drug trade, easy access to firearms, substance misuse including alcohol, mental health problems, firearm laws, social attitudes, economic differences and occupations such as being a police officer. Where guns are more common, altercations more often end in death. Before management begins it should be verified the area is safe. This is followed by stopping major bleeding, then as ...

Puncture Wound
Penetrating trauma is an open wound injury that occurs when an object pierces the skin and enters a tissue of the body, creating a deep but relatively narrow entry wound. In contrast, a blunt or ''non-penetrating'' trauma may have some deep damage, but the overlying skin is not necessarily broken and the wound is still closed to the outside environment. The penetrating object may remain in the tissues, come back out the path it entered, or pass through the full thickness of the tissues and exit from another area. A penetrating injury in which an object enters the body or a structure and passes all the way through an exit wound is called a perforating trauma, while the term ''penetrating trauma'' implies that the object does not perforate wholly through. In gunshot wounds, perforating trauma is associated with an entrance wound and an often larger exit wound. Penetrating trauma can be caused by a foreign object or by fragments of a broken bone. Usually occurring in violent cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pressure Ulcer
Pressure ulcers, also known as pressure sores, bed sores or pressure injuries, are localised damage to the skin and/or underlying tissue that usually occur over a bony prominence as a result of usually long-term pressure, or pressure in combination with shear or friction. The most common sites are the skin overlying the sacrum, coccyx, heels, and hips, though other sites can be affected, such as the elbows, knees, ankles, back of shoulders, or the back of the cranium. Pressure ulcers occur due to pressure applied to soft tissue resulting in completely or partially obstructed blood flow to the soft tissue. Shear is also a cause, as it can pull on blood vessels that feed the skin. Pressure ulcers most commonly develop in individuals who are not moving about, such as those who are on chronic bedrest or consistently use a wheelchair. It is widely believed that other factors can influence the tolerance of skin for pressure and shear, thereby increasing the risk of pressure ulcer d ...

Injury
An injury is any physiological damage to living tissue caused by immediate physical stress. An injury can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries. Treatment of a major injury is typically carried out by a health professional and varies greatly depending on the nature of the injury. Traffic collisions are the most common cause of accidental injury and injury-related death among humans. Injuries are distinct from chronic conditions, psychological trauma, infections, or medical procedures, though injury can be a contributing factor to any of these. Several major health organizations have established systems for the classification and description of human injuries. Occurrence Injuries may be intentional or unintentional. Intentional injuries may be acts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Healing
With physical trauma or disease suffered by an organism, healing involves the repairing of damaged tissue(s), organs and the biological system as a whole and resumption of (normal) functioning. Medicine includes the process by which the cells in the body regenerate and repair to reduce the size of a damaged or necrotic area and replace it with new living tissue. The replacement can happen in two ways: by ''regeneration'' in which the necrotic cells are replaced by new cells that form "like" tissue as was originally there; or by ''repair'' in which injured tissue is replaced with scar tissue. Most organs will heal using a mixture of both mechanisms. Within surgery, healing is more often referred to as recovery, and postoperative recovery has historically been viewed simply as restitution of function and readiness for discharge. More recently, it has been described as an energy‐requiring process to decrease physical symptoms, reach a level of emotional well‐being, regain func ...

Splinter
A splinter (also known as a sliver) is a fragment of a larger object, or a foreign body that penetrates or is purposely injected into a body. The foreign body must be lodged inside tissue to be considered a splinter. Splinters may cause initial pain through ripping of flesh and muscle, or infection through bacteria on the foreign object. Splinters commonly consist of wood, but there are many other types, for example, other common types of splinters are glass, plastic, metal, and spines of animals. As with any wound that breaks the skin, splinters can lead to infection, which if left untreated could develop into more serious complications. If a splinter is in the body for more than 2–3 days, or if the wound shows signs of inflammation or tenderness (whether the splinter was removed or not), advice should be sought from a doctor. Getting a splinter Generally, a splinter causes an initial feeling of pain as the sharp object makes its initial penetration through the body. Th ...

Plastic Surgery
Plastic surgery is a surgical specialty involving the restoration, reconstruction or alteration of the human body. It can be divided into two main categories: reconstructive surgery and cosmetic surgery. Reconstructive surgery includes craniofacial surgery, hand surgery, microsurgery, and the treatment of burns. While reconstructive surgery aims to reconstruct a part of the body or improve its functioning, cosmetic (or aesthetic) surgery aims at improving the appearance of it. Etymology The word ''plastic'' in ''plastic surgery'' means "reshaping" and comes from the Greek πλαστική (τέχνη), ''plastikē'' (''tekhnē''), "the art of modelling" of malleable flesh. This meaning in English is seen as early as 1598. The surgical definition of "plastic" first appeared in 1839, preceding the modern "engineering material made from petroleum" sense by 70 years. History Treatments for the plastic repair of a broken nose are first mentioned in the Egyptian medical text ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
