A bruise, also known as a contusion, is a type of hematoma of tissue, [3] the most common cause being capillaries damaged by trauma, causing localized bleeding that extravasates into the surrounding interstitial tissues. Most bruises occur close enough to the epidermis such that the bleeding causes a visible discoloration.
A pulmonary contusion, also known as lung contusion, is a bruise of the lung, caused by chest trauma. As a result of damage to capillaries , blood and other fluids accumulate in the lung tissue. The excess fluid interferes with gas exchange , potentially leading to inadequate oxygen levels ( hypoxia ).
A soft tissue injury is the damage of muscles, ligaments and tendons throughout the body. Common soft tissue injuries usually occur from a sprain, strain, a one-off blow resulting in a contusion or overuse of a particular part of the body. Soft tissue injuries can result in pain, swelling, bruising and loss of function. [1]
Identifying an allergy to penicillin requires a hypersensitivity skin test, which diagnoses IgE-mediated immune responses caused by penicillin. This test is typically performed by an allergist who uses a skin-prick and intradermal injection of penicilloyl-polylysine, a negative control (normal saline), and a positive control ( histamine ).
The abdominal organs. Signs and symptoms are not seen in early days and after some days initial pain is seen. People injured in motor vehicle collisions may present with a "seat belt sign", bruising on the abdomen along the site of the lap portion of the safety belt; this sign is associated with a high rate of injury to the abdominal organs.

Cerebral contusion (Latin: contusio cerebri), a form of traumatic brain injury, is a bruise of the brain tissue. [2] Like bruises in other tissues, cerebral contusion can be associated with multiple microhemorrhages, small blood vessel leaks into brain tissue. Contusion occurs in 20–30% of severe head injuries.

Antibiotics are some of the most powerful tools in medicine. They’re prescribed to treat a variety of infections caused by bacteria, such as urinary tract infections, most ear infections, strep ...
The reaction is also seen in the other diseases caused by spirochetes: Lyme disease, relapsing fever, and leptospirosis. [4] There have been case reports of the Jarisch–Herxheimer reaction accompanying treatment of other infections, including Q fever , bartonellosis , brucellosis , trichinellosis , and African trypanosomiasis .
