Self-harm refers to intentional behaviors that cause harm to oneself. This is most commonly regarded as direct injury of one's own skin tissues, commonly with suicidal intention. Other terms such as cutting, self-injury, and self-mutilation have been used for any self-harming behavior regardless of suicidal intent. Common forms of self-harm include damaging the skin with a sharp object or scratching with the fingernails, hitting, or burning. The exact bounds of self-harm are imprecise, but generally exclude tissue damage that occurs as an unintended side-effect of eating disorders or substance abuse, as well as more societally acceptable body modification such as tattoos and piercings.
Strangling or strangulation is compression of the neck that may lead to unconsciousness or death by causing an increasingly hypoxic state in the brain by restricting the flow of oxygen through the trachea. Fatal strangulation typically occurs in cases of violence, accidents, and is one of two main ways that hanging causes death.
An injury is any physiological damage to living tissue 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. Injuries can occur in any part of the body, and different symptoms are associated with different injuries.
Airway management includes a set of maneuvers and medical procedures performed to prevent and relieve airway obstruction. This ensures an open pathway for gas exchange between a patient's lungs and the atmosphere. This is accomplished by either clearing a previously obstructed airway; or by preventing airway obstruction in cases such as anaphylaxis, the obtunded patient, or medical sedation. Airway obstruction can be caused by the tongue, foreign objects, the tissues of the airway itself, and bodily fluids such as blood and gastric contents (aspiration).
Major trauma is any injury that has the potential to cause prolonged disability or death. There are many causes of major trauma, blunt and penetrating, including falls, motor vehicle collisions, stabbing wounds, and gunshot wounds. Depending on the severity of injury, quickness of management, and transportation to an appropriate medical facility may be necessary to prevent loss of life or limb. The initial assessment is critical, and involves a physical evaluation and also may include the use of imaging tools to determine the types of injuries accurately and to formulate a course of treatment.
Erotic asphyxiation is the intentional restriction of oxygen to the brain for the purposes of sexual arousal. With a partner, the act often involves strangulation. The term autoerotic asphyxiation is used when the act is done by a person to themself. Colloquially, a person engaging in the activity is sometimes called a gasper. Erotic asphyxiation can lead to accidental death due to asphyxia.
A suicide method is any means by which a person may choose to end their life. Suicide attempts do not always result in death, and a non-fatal suicide attempt can leave the person with serious physical injuries, long-term health problems, or brain damage.
Suicide prevention is a collection of efforts to reduce the risk of suicide. Suicide is often preventable, and the efforts to prevent it may occur at the individual, relationship, community, and society level. Suicide is a serious public health problem that can have long-lasting effects on individuals, families, and communities. Preventing suicide requires strategies at all levels of society. This includes prevention and protective strategies for individuals, families, and communities. Suicide can be prevented by learning the warning signs, promoting prevention and resilience, and committing to social change.
A suicide pact is an agreed plan between two or more individuals to die by suicide. The plan may be to die together, or separately and closely timed.
Ludwig's angina is a type of severe cellulitis involving the floor of the mouth and is often caused by bacterial sources. Early in the infection, the floor of the mouth raises due to swelling, leading to difficulty swallowing saliva. As a result, patients may present with drooling and difficulty speaking. As the condition worsens, the airway may be compromised and hardening of the spaces on both sides of the tongue may develop. Overall, this condition has a rapid onset over a few hours.
A gunshot wound (GSW) is a penetrating injury caused by a projectile shot from a gun. Damage may include bleeding, bone fractures, organ damage, wound infection, and loss of the ability to move part of the body. 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. In severe cases, although not uncommon, the injury is fatal. Long-term complications can include bowel obstruction, failure to thrive, neurogenic bladder and paralysis, recurrent cardiorespiratory distress and pneumothorax, hypoxic brain injury leading to early dementia, amputations, chronic pain and pain with light touch (hyperalgesia), deep venous thrombosis with pulmonary embolus, limb swelling and debility, and lead poisoning.
Suicide is the act of intentionally causing one's own death. Mental disorders, physical disorders, and substance abuse are common risk factors.
Facial trauma, also called maxillofacial trauma, is any physical trauma to the face. Facial trauma can involve soft tissue injuries such as burns, lacerations and bruises, or fractures of the facial bones such as nasal fractures and fractures of the jaw, as well as trauma such as eye injuries. Symptoms are specific to the type of injury; for example, fractures may involve pain, swelling, loss of function, or changes in the shape of facial structures.
Paracetamol poisoning, also known as acetaminophen poisoning, is caused by excessive use of the medication paracetamol (acetaminophen). Most people have few or non-specific symptoms in the first 24 hours following overdose. These symptoms include feeling tired, abdominal pain, or nausea. This is typically followed by absence of symptoms for a couple of days, after which yellowish skin, blood clotting problems, and confusion occurs as a result of liver failure. Additional complications may include kidney failure, pancreatitis, low blood sugar, and lactic acidosis. If death does not occur, people tend to recover fully over a couple of weeks. Without treatment, death from toxicity occurs 4 to 18 days later.
Benzodiazepine overdose describes the ingestion of one of the drugs in the benzodiazepine class in quantities greater than are recommended or generally practiced. The most common symptoms of overdose include central nervous system (CNS) depression, impaired balance, ataxia, and slurred speech. Severe symptoms include coma and respiratory depression. Supportive care is the mainstay of treatment of benzodiazepine overdose. There is an antidote, flumazenil, but its use is controversial.
Gender differences in suicide rates have been shown to be significant. There are different rates of suicides and suicidal behavior between males and females. While females more often have suicidal thoughts, males die by suicide more frequently. This discrepancy is also known as the gender paradox in suicide.
A suicide attempt is an act in which an individual tries to kill themselves but survives. Mental health professionals discourage describing suicide attempts as "failed" or "unsuccessful", as doing so may imply that a suicide resulting in death is a successful or desirable outcome.
Psychological autopsy in suicidology is a systematic procedure for evaluating suicidal intention in equivocal cases. It was invented by American psychologists Norman Farberow and Edwin S. Shneidman during their time working at the Los Angeles Suicide Prevention Center, which they founded in 1958.
Alan Lee Berman also known as Lanny Berman, is an American psychologist, psychotherapist, and suicidologist. He is an adjunct professor of Psychiatry and Behavioral Sciences at Johns Hopkins School of Medicine. Berman was formerly the executive director of the American Association of Suicidology. He is a fellow of the American Psychological Association and the International Association for Suicide Research. Berman has a private practice in psychological and forensic consultation.
Suicide and trauma is the increased risk of suicide that is caused by psychological trauma.
