A state of prolonged irreversible cessation of all brain activity, including lower brain stem function with the complete absence of voluntary movements, responses to stimuli, brain stem reflexes, and spontaneous respirations. Reversible conditions which mimic this clinical state (e.g., sedative overdose, hypothermia, etc.) are excluded prior to making the determination of brain death. (From Adams et al., Principles of Neurology, 6th ed, pp348-9)
Irreversible cessation of all bodily functions, manifested by absence of spontaneous breathing and total loss of cardiovascular and cerebral functions.
Individuals supplying living tissue, organs, cells, blood or blood components for transfer or transplantation to histocompatible recipients.
The administrative procedures involved with acquiring TISSUES or organs for TRANSPLANTATION through various programs, systems, or organizations. These procedures include obtaining consent from TISSUE DONORS and arranging for transportation of donated tissues and organs, after TISSUE HARVESTING, to HOSPITALS for processing and transplantation.
The termination of the cell's ability to carry out vital functions such as metabolism, growth, reproduction, responsiveness, and adaptability.
Factors which produce cessation of all vital bodily functions. They can be analyzed from an epidemiologic viewpoint.
Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.
Changes in the amounts of various chemicals (neurotransmitters, receptors, enzymes, and other metabolites) specific to the area of the central nervous system contained within the head. These are monitored over time, during sensory stimulation, or under different disease states.
The procedure of removing TISSUES, organs, or specimens from DONORS for reuse, such as TRANSPLANTATION.
A transient absence of spontaneous respiration.
A profound state of unconsciousness associated with depressed cerebral activity from which the individual cannot be aroused. Coma generally occurs when there is dysfunction or injury involving both cerebral hemispheres or the brain stem RETICULAR FORMATION.
The state or condition of being a human individual accorded moral and/or legal rights. Criteria to be used to determine this status are subject to debate, and range from the requirement of simply being a human organism to such requirements as that the individual be self-aware and capable of rational thought and moral agency.
Vegetative state refers to the neurocognitive status of individuals with severe brain damage, in whom physiologic functions (sleep-wake cycles, autonomic control, and breathing) persist, but awareness (including all cognitive function and emotion) is abolished.
Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.
Transference of an organ between individuals of the same species or between individuals of different species.
The state that distinguishes organisms from inorganic matter, manifested by growth, metabolism, reproduction, and adaptation. It includes the course of existence, the sum of experiences, the mode of existing, or the fact of being. Over the centuries inquiries into the nature of life have crossed the boundaries from philosophy to biology, forensic medicine, anthropology, etc., in creative as well as scientific literature. (Random House Unabridged Dictionary, 2d ed; Dr. James H. Cassedy, NLM History of Medicine Division)
The part of the brain that connects the CEREBRAL HEMISPHERES with the SPINAL CORD. It consists of the MESENCEPHALON; PONS; and MEDULLA OBLONGATA.
Imaging techniques used to colocalize sites of brain functions or physiological activity with brain structures.
Conceptual response of the person to the various aspects of death, which are based on individual psychosocial and cultural experience.
The science or philosophy of law. Also, the application of the principles of law and justice to health and medicine.
The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.
The principles of professional conduct concerning the rights and duties of the physician, relations with patients and fellow practitioners, as well as actions of the physician in patient care and interpersonal relations with patient families.
Care provided patients requiring extraordinary therapeutic measures in order to sustain and prolong life.
Elicitation of a rotatory nystagmus by stimulating the semicircular canals with water or air which is above or below body temperature. In warm caloric stimulation a rotatory nystagmus is developed toward the side of the stimulated ear; in cold, away from the stimulated side. Absence of nystagmus indicates the labyrinth is not functioning.
The point at which religious ensoulment or PERSONHOOD is considered to begin.
Withholding or withdrawal of a particular treatment or treatments, often (but not necessarily) life-prolonging treatment, from a patient or from a research subject as part of a research protocol. The concept is differentiated from REFUSAL TO TREAT, where the emphasis is on the health professional's or health facility's refusal to treat a patient or group of patients when the patient or the patient's representative requests treatment. Withholding of life-prolonging treatment is usually indexed only with EUTHANASIA, PASSIVE, unless the distinction between withholding and withdrawing treatment, or the issue of withholding palliative rather than curative treatment, is discussed.
Recording of electric currents developed in the brain by means of electrodes applied to the scalp, to the surface of the brain, or placed within the substance of the brain.
Informed consent given by someone other than the patient or research subject.
Elements of limited time intervals, contributing to particular results or situations.
General dysfunction of an organ occurring immediately following its transplantation. The term most frequently refers to renal dysfunction following KIDNEY TRANSPLANTATION.

An organophosphate cholinesterase inhibitor that is used as an insecticide.
Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS). (From Childs Nerv Syst 1992 Sep; 8(6):301-6)
The process by which organs are kept viable outside of the organism from which they were removed (i.e., kept from decay by means of a chemical agent, cooling, or a fluid substitute that mimics the natural state within the organism).
Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.

The case for a statutory 'definition of death'. (1/411)

Karen Quinlan, the American girl who has lain in deep coma for many months, is still 'alive', that is to say, her heart is still beating and brain death has not occurred. However, several other cases have raised difficult issues about the time of death. Dr Skegg argues that there is a case for a legal definition of death enshrined in statutory form. He suggests that many of the objections to a statutory provision on death are misplaced, and that a statute concerning the occurrence of death could remove all doubts in the minds of both doctors and public as to whether a 'beating heart cadaver' was dead or alive for legal purposes.  (+info)

A matter of life and death: what every anesthesiologist should know about the medical, legal, and ethical aspects of declaring brain death. (2/411)

Accurate criteria for death are increasingly important as it becomes more difficult for the public to distinguish between patients who are still alive from those who, through the aid of medical technology, merely look like they are alive even though they are dead. Patients and their families need to know that a clear line can be drawn between life and death, and that patients who are alive will not be unintentionally treated as though they are dead. For the public to trust the pronouncements of medical doctors as to whether a patient is dead or alive, the criteria must be unambiguous, understandable, and infallible. It is equally important to physicians that accurate, infallible criteria define death. Physicians need to know that a clear line can be drawn between life and death so that patients who are dead are not treated as though they are alive. Such criteria enable us to terminate expensive medical care to corpses. Clear criteria for death also allow us to ethically request the gift of vital organs. Clear, infallible criteria allow us to assure families and society that one living person will not be intentionally or unintentionally killed for the sake of another. The pressure of organ scarcity must not lead physicians to allow the criteria for life and death to become blurred because of the irreparable harm this would cause to the patient-physician relationship and the devastating impact it could have on organ transplantation. As the cases presented here illustrate, anesthesiologists have an important responsibility in the process of assuring that some living patients are not sacrificed to benefit others. Criteria for declaring death should be familiar to every anesthesiologist participating in organ retrieval. Before accepting the responsibility of maintaining a donor for vital organ collection, the anesthesiologist should review data supplied in the chart supporting the diagnosis of brain death and seriously question inconsistencies and inadequate testing conditions. Knowledge of brain death criteria and proper application of these criteria could have changed the course of each of the cases presented.  (+info)

Donor catecholamine use reduces acute allograft rejection and improves graft survival after cadaveric renal transplantation. (3/411)

BACKGROUND: Epidemiological data implicate that renal transplants from living unrelated donors result in superior survival rates as compared with cadaveric grafts, despite a higher degree of human lymphocyte antigen (HLA) mismatching. We undertook a center-based case control study to identify donor-specific determinants affecting early outcome in cadaveric transplantation. METHODS: The study database consisted of 152 consecutive cadaveric renal transplants performed at our center between June 1989 and September 1998. Of these, 24 patients received a retransplant. Donor kidneys were allocated on the basis of prospective HLA matching according to the Eurotransplant rules of organ sharing. Immunosuppressive therapy consisted of a cyclosporine-based triple-drug regimen. In 67 recipients, at least one acute rejection episode occurred during the first month after transplantation. They were taken as cases, and the remaining 85 patients were the controls. Stepwise logistic regression was done on donor-specific explanatory variables obtained from standardized Eurotransplant Necrokidney reports. In a secondary evaluation, the impact on graft survival in long-term follow-up was further measured by applying a Cox regression model. The mean follow-up of all transplant recipients was 3.8 years (SD 2.7 years). RESULTS: Donor age [odds ratio (OR) 1.05; 95% CI, 1.02 to 1.08], traumatic brain injury as cause of death (OR 2.75; 95% CI, 1.16 to 6. 52), and mismatch on HLA-DR (OR 3.0; 95% CI, 1.47 to 6.12) were associated with an increased risk of acute rejection, whereas donor use of dopamine (OR 0.22; 95% CI, 0.09 to 0.51) and/or noradrenaline (OR 0.24; 95% CI, 0.10 to 0.60) independently resulted in a significant beneficial effect. In the multivariate Cox regression analysis, both donor treatment with dopamine (HR 0.44; 95% CI, 0.22 to 0.84) and noradrenaline (HR 0.30; 95% CI, 0.10 to 0.87) remained a significant predictor of superior graft survival in long-term follow-up. CONCLUSIONS: Our data strongly suggest that the use of catecholamines in postmortal organ donors during intensive care results in immunomodulating effects and improves graft survival in long-term follow-up. These findings may at least partially be explained by down-regulating effects of adrenergic substances on the expression of adhesion molecules (VCAM, E-selectin) in the vessel walls of the graft.  (+info)

N18 in median somatosensory evoked potentials: a new indicator of medullary function useful for the diagnosis of brain death. (4/411)

OBJECTIVES: To record N18 in median somatosensory evoked potentials (SEPs) for deeply comatose or brain dead patients and to demonstrate the usefulness of N18 for the diagnosis of brain death in comparison with auditory brain stem responses (ABRs) and P13/14 in median SEPs, which have been conventionally used as complementary tests for the diagnosis of brain death. METHODS: Subjects were 19 deeply comatose or brain dead patients. Thirteen recordings were performed in deeply comatose but not brain dead conditions, and 12 recordings were performed in brain death. N18 was evaluated in the CPi-C2S lead (or other scalp-C2S leads) to obtain a flat baseline. RESULTS: N18 was preserved in 12 of 13 non-brain dead comatose recordings whereas it was completely lost for all of the 12 brain death recordings. P13/14 in median SEPs was preserved for all the comatose recordings, whereas apparent P13/14-like potentials, usually of low amplitude, were seen in nine of 12 brain death recordings-that is, frequent false positives. The ABRs already showed features which were characteristic for brain death (loss of components other than wave 1 or small wave 2) for four comatose recordings, in three of which N18 was preserved. The last result not only corresponds with the fact that ABRs can evaluate pontine and midbrain functions and not medullary function, but further supports the medullary origin of N18. In the four patients followed up for the course of progression from coma to brain death, N18s preserved in normal size during the comatose state were completely lost after brain death was established. CONCLUSIONS: The N18 potential is generated by the cuneate nucleus in the medulla oblongata in the preceding studies. N18 is suggested to be a promising tool for the diagnosis of brain death because there were no false positives and rare false negatives in the present series for detecting the remaining brain stem function.  (+info)

The ambiguity about death in Japan: an ethical implication for organ procurement. (5/411)

In the latter half of the twentieth century, developed countries of the world have made tremendous strides in organ donation and transplantation. However, in this area of medicine, Japan has been slow to follow. Japanese ethics, deeply rooted in religion and tradition, have affected their outlook on life and death. Because the Japanese have only recently started to acknowledge the concept of brain death, transplantation of major organs has been hindered in that country. Currently, there is a dual definition of death in Japan, intended to satisfy both sides of the issue. This interesting paradox, which still stands to be fully resolved, illustrates the contentious conflict between medical ethics and medical progress in Japan.  (+info)

Implications of ischemic penumbra for the diagnosis of brain death. (6/411)

The data reviewed here suggest the possibility that a global reduction of blood supply to the whole brain or solely to the infratentorial structures down to the range of ischemic penumbra for several hours or a few days may lead to misdiagnosis of irreversible brain or brain stem damage in a subset of deeply comatose patients with cephalic areflexia. The following proposals are advanced: 1) the lack of any set of clinically detectable brain functions does not provide a safe diagnosis of brain or brain stem death; 2) apnea testing may induce irreversible brain damage and should be abandoned; 3) moderate hypothermia, antipyresis, prevention of arterial hypotension, and occasionally intra-arterial thrombolysis may contribute to good recovery of a possibly large subset of cases of brain injury currently regarded as irreversible; 4) confirmatory tests for brain death should not replace or delay the administration of potentially effective therapeutic measures; 5) in order to validate confirmatory tests, further research is needed to relate their results to specific levels of blood supply to the brain. The current criteria for the diagnosis of brain death should be revised.  (+info)

Brain death diagnosis in misleading conditions. (7/411)

The necessity of defining brain death (BD) arose from technological development in medical science. The definition of this concept had practical consequences and opened the way to organ donation from BD patients. Nowadays, the imbalance between the number of organs available for transplantation and the size of the demand is becoming critical. In most laboratories, a BD diagnosis is made according to precise criteria and in a well-defined process. BD diagnosis should be improved, not only to assure the safety and to preserve the human dignity of the patient, but also in order to increase the rate of organ donation. By analysing some epidemiological parameters in BD diagnosis and organ donation, it appears that BD diagnoses can be made more often and more rapidly if one has a reliable, accurate, and safe confirmatory test, especially under misleading conditions (hypothermia, drugs, metabolic disturbances). In our experience, the use of multimodality evoked potentials (MEPs) to confirm a BD diagnosis has many advantages: MEPs can be rapidly performed at the patient's bedside, assess the brain stem as well as the cerebral cortex, and are innocuous for the patient. Moreover, their insensitivity to the aforementioned misleading factors is sufficient to distinguish BD from clinical and EEG states that mimic BD. They give an immediate diagnosis, and no delay is required in BD confirmation if there is sufficient cause to account for BD. MEPs are a safe, accurate, and reliable tool for confirming a BD diagnosis, and their use can improve the organ donation rate while preserving the safety of the patient.  (+info)

Re-examining death: against a higher brain criterion. (8/411)

While there is increasing pressure on scarce health care resources, advances in medical science have blurred the boundary between life and death. Individuals can survive for decades without consciousness and individuals whose whole brains are dead can be supported for extended periods. One suggested response is to redefine death, justifying a higher brain criterion for death. This argument fails because it conflates two distinct notions about the demise of human beings--the one, biological and the other, ontological. Death is a biological phenomenon. This view entails the rejection of a higher brain criterion of death. Moreover, I claim that the justification of the whole brain (or brain stem) criterion of death is also cast into doubt by these advances in medical science. I proceed to argue that there is no need to redefine death in order to identify which treatments ought to be provided for the permanently and irreversibly unconscious. There are already clear treatment guidelines.  (+info)

The committee defined "brain death" as follows:

* The absence of any clinical or electrophysiological signs of consciousness, including the lack of response to pain, light, sound, or other stimuli.
* The absence of brainstem reflexes, such as pupillary reactivity, oculocephalic reflex, and gag reflex.
* The failure of all brain waves, including alpha, beta, theta, delta, and epsilon waves, as detected by electroencephalography (EEG).
* The absence of any other clinical or laboratory signs of life, such as heartbeat, breathing, or blood circulation.

The definition of brain death is important because it provides a clear and consistent criteria for determining death in medical settings. It helps to ensure that patients who are clinically dead are not inappropriately kept on life support, and that organ donation can be performed in a timely and ethical manner.

In medical terms, death is defined as the irreversible cessation of all bodily functions that are necessary for life. This includes the loss of consciousness, the absence of breathing, heartbeat, and other vital signs. Brain death, which occurs when the brain no longer functions, is considered a definitive sign of death.

The medical professionals use various criteria to determine death, such as:

1. Cessation of breathing: When an individual stops breathing for more than 20 minutes, it is considered a sign of death.
2. Cessation of heartbeat: The loss of heartbeat for more than 20 minutes is another indicator of death.
3. Loss of consciousness: If an individual is unresponsive and does not react to any stimuli, it can be assumed that they have died.
4. Brain death: When the brain no longer functions, it is considered a definitive sign of death.
5. Decay of body temperature: After death, the body's temperature begins to decrease, which is another indicator of death.

In some cases, medical professionals may use advanced technologies such as electroencephalography (EEG) or functional magnetic resonance imaging (fMRI) to confirm brain death. These tests can help determine whether the brain has indeed ceased functioning and if there is no hope of reviving the individual.

It's important to note that while death is a natural part of life, it can be a difficult and emotional experience for those who are left behind. It's essential to provide support and care to the family members and loved ones of the deceased during this challenging time.

There are several different types of brain injuries that can occur, including:

1. Concussions: A concussion is a type of mild traumatic brain injury that occurs when the brain is jolted or shaken, often due to a blow to the head.
2. Contusions: A contusion is a bruise on the brain that can occur when the brain is struck by an object, such as during a car accident.
3. Coup-contrecoup injuries: This type of injury occurs when the brain is injured as a result of the force of the body striking another object, such as during a fall.
4. Penetrating injuries: A penetrating injury occurs when an object pierces the brain, such as during a gunshot wound or stab injury.
5. Blast injuries: This type of injury occurs when the brain is exposed to a sudden and explosive force, such as during a bombing.

The symptoms of brain injuries can vary depending on the severity of the injury and the location of the damage in the brain. Some common symptoms include:

* Headaches
* Dizziness or loss of balance
* Confusion or disorientation
* Memory loss or difficulty with concentration
* Slurred speech or difficulty with communication
* Vision problems, such as blurred vision or double vision
* Sleep disturbances
* Mood changes, such as irritability or depression
* Personality changes
* Difficulty with coordination and balance

In some cases, brain injuries can be treated with medication, physical therapy, and other forms of rehabilitation. However, in more severe cases, the damage may be permanent and long-lasting. It is important to seek medical attention immediately if symptoms persist or worsen over time.

There are several types of apnea that can occur during sleep, including:

1. Obstructive sleep apnea (OSA): This is the most common type of apnea and occurs when the airway is physically blocked by the tongue or other soft tissue in the throat, causing breathing to stop for short periods.
2. Central sleep apnea (CSA): This type of apnea occurs when the brain fails to send the proper signals to the muscles that control breathing, resulting in a pause in breathing.
3. Mixed sleep apnea (MSA): This type of apnea is a combination of OSA and CSA, where both central and obstructive factors contribute to the pauses in breathing.
4. Hypopneic apnea: This type of apnea is characterized by a decrease in breathing, but not a complete stop.
5. Hypercapnic apnea: This type of apnea is caused by an excessive buildup of carbon dioxide in the blood, which can lead to pauses in breathing.

The symptoms of apnea can vary depending on the type and severity of the condition, but may include:

* Pauses in breathing during sleep
* Waking up with a dry mouth or sore throat
* Morning headaches
* Difficulty concentrating or feeling tired during the day
* High blood pressure
* Heart disease

Treatment options for apnea depend on the underlying cause, but may include:

* Lifestyle changes, such as losing weight, avoiding alcohol and sedatives before bedtime, and sleeping on your side
* Oral appliances or devices that advance the position of the lower jaw and tongue
* Continuous positive airway pressure (CPAP) therapy, which involves wearing a mask during sleep to deliver a constant flow of air pressure into the airways
* Bi-level positive airway pressure (BiPAP) therapy, which involves two levels of air pressure: one for inhalation and another for exhalation
* Surgery to remove excess tissue in the throat or correct physical abnormalities that are contributing to the apnea.

In medical terminology, coma is defined as a state of prolonged unconsciousness that lasts for more than 24 hours and is characterized by a lack of responsiveness to stimuli, including pain, light, sound, or touch. Coma can be caused by a variety of factors, such as:

1. Traumatic brain injury: Coma can result from a severe head injury that causes damage to the brain.
2. Stroke: A stroke can cause coma if it affects a large part of the brain.
3. Infections: Bacterial or viral infections can spread to the brain and cause coma.
4. Poisoning: Toxic substances, such as drugs or chemicals, can cause coma by damaging the brain.
5. Hypoxia: Lack of oxygen to the brain can cause coma.
6. Hypoglycemia: Low blood sugar can cause coma.
7. Metabolic disorders: Certain metabolic disorders, such as diabetic ketoacidosis or hypothyroidism, can cause coma.
8. Electrolyte imbalance: An imbalance of electrolytes, such as sodium or potassium, can cause coma.
9. Chronic conditions: Certain chronic conditions, such as brain tumors or degenerative diseases like Alzheimer's or Parkinson's, can cause coma over time.

It is important to note that a coma is different from a vegetative state, which is characterized by awakening and opening one's eyes but lacking any meaningful response to stimuli. A comatose patient may also exhibit automatic responses, such as breathing or reacting to pain, but they are not aware of their surroundings or able to communicate.

The diagnosis of coma is typically made by a neurologist based on the patient's medical history, physical examination, and results of diagnostic tests such as electroencephalography (EEG) or imaging studies like computed tomography (CT) or magnetic resonance imaging (MRI). Treatment of coma depends on the underlying cause and may include supportive care, medication, or surgical intervention.

The diagnosis of PVS is made by a team of healthcare professionals, including neurosurgeons, neurologists, and rehabilitation specialists. The diagnosis is based on a combination of clinical examination and medical imaging studies, such as electroencephalograms (EEGs) and functional magnetic resonance imaging (fMRI).

There are three main criteria for diagnosing PVS:

1. Lack of awareness: The patient is unable to open their eyes or respond purposefully to stimuli.
2. Lack of purposeful movement: The patient is unable to move voluntarily, except for possibly some reflex movements.
3. Abnormal sleep-wake cycle: The patient exhibits a persistent vegetative state sleep-wake cycle, characterized by periods of sleep and wakefulness that are not consistent with normal sleep patterns.

Treatment for PVS is focused on supporting the patient's basic needs, such as breathing and nutrition, and managing any underlying medical conditions. However, there is no cure for PVS, and the condition is often permanent. Some patients may eventually recover some cognitive and behavioral functions over time, but many will remain in a state of persistent vegetative state for the rest of their lives.

In summary, the definition of persistent vegetative state (PVS) in the medical field refers to a severe loss of cognitive and behavioral function, resulting from traumatic brain injury or other causes, characterized by a lack of awareness, purposeful movement, and abnormal sleep-wake cycle. The diagnosis is made by a team of healthcare professionals, and treatment focuses on supporting the patient's basic needs and managing any underlying medical conditions.

Brain neoplasms can arise from various types of cells in the brain, including glial cells (such as astrocytes and oligodendrocytes), neurons, and vascular tissues. The symptoms of brain neoplasms vary depending on their size, location, and type, but may include headaches, seizures, weakness or numbness in the limbs, and changes in personality or cognitive function.

There are several different types of brain neoplasms, including:

1. Meningiomas: These are benign tumors that arise from the meninges, the thin layers of tissue that cover the brain and spinal cord.
2. Gliomas: These are malignant tumors that arise from glial cells in the brain. The most common type of glioma is a glioblastoma, which is aggressive and hard to treat.
3. Pineal parenchymal tumors: These are rare tumors that arise in the pineal gland, a small endocrine gland in the brain.
4. Craniopharyngiomas: These are benign tumors that arise from the epithelial cells of the pituitary gland and the hypothalamus.
5. Medulloblastomas: These are malignant tumors that arise in the cerebellum, specifically in the medulla oblongata. They are most common in children.
6. Acoustic neurinomas: These are benign tumors that arise on the nerve that connects the inner ear to the brain.
7. Oligodendrogliomas: These are malignant tumors that arise from oligodendrocytes, the cells that produce the fatty substance called myelin that insulates nerve fibers.
8. Lymphomas: These are cancers of the immune system that can arise in the brain and spinal cord. The most common type of lymphoma in the CNS is primary central nervous system (CNS) lymphoma, which is usually a type of B-cell non-Hodgkin lymphoma.
9. Metastatic tumors: These are tumors that have spread to the brain from another part of the body. The most common types of metastatic tumors in the CNS are breast cancer, lung cancer, and melanoma.

These are just a few examples of the many types of brain and spinal cord tumors that can occur. Each type of tumor has its own unique characteristics, such as its location, size, growth rate, and biological behavior. These factors can help doctors determine the best course of treatment for each patient.

DGF can occur in various types of transplantations, including kidney, liver, heart, and lung transplants. The symptoms of DGF may include decreased urine production, decreased respiratory function, and abnormal liver enzymes. Treatment for DGF typically involves supportive care such as fluid and electrolyte replacement, management of infections, and immunosuppressive medications to prevent rejection. In some cases, additional surgical interventions may be necessary.

The diagnosis of DGF is based on clinical evaluation and laboratory tests such as blood chemistry, urinalysis, and biopsy findings. The prognosis for DGF varies depending on the underlying cause and the severity of the condition. In general, prompt recognition and treatment of DGF can improve outcomes and reduce the risk of complications.

In summary, delayed graft function is a common complication in transplantation that can result from various factors. Prompt diagnosis and treatment are essential to prevent long-term damage and improve outcomes for the transplanted organ or tissue.

The word "edema" comes from the Greek word "oidema", meaning swelling.

The term ischemia refers to the reduction of blood flow, and it is often used interchangeably with the term stroke. However, not all strokes are caused by ischemia, as some can be caused by other factors such as bleeding in the brain. Ischemic stroke accounts for about 87% of all strokes.

There are different types of brain ischemia, including:

1. Cerebral ischemia: This refers to the reduction of blood flow to the cerebrum, which is the largest part of the brain and responsible for higher cognitive functions such as thought, emotion, and voluntary movement.
2. Cerebellar ischemia: This refers to the reduction of blood flow to the cerebellum, which is responsible for coordinating and regulating movement, balance, and posture.
3. Brainstem ischemia: This refers to the reduction of blood flow to the brainstem, which is responsible for controlling many of the body's automatic functions such as breathing, heart rate, and blood pressure.
4. Territorial ischemia: This refers to the reduction of blood flow to a specific area of the brain, often caused by a blockage in a blood vessel.
5. Global ischemia: This refers to the reduction of blood flow to the entire brain, which can be caused by a cardiac arrest or other systemic conditions.

The symptoms of brain ischemia can vary depending on the location and severity of the condition, but may include:

1. Weakness or paralysis of the face, arm, or leg on one side of the body
2. Difficulty speaking or understanding speech
3. Sudden vision loss or double vision
4. Dizziness or loss of balance
5. Confusion or difficulty with memory
6. Seizures
7. Slurred speech or inability to speak
8. Numbness or tingling sensations in the face, arm, or leg
9. Vision changes, such as blurred vision or loss of peripheral vision
10. Difficulty with coordination and balance.

It is important to seek medical attention immediately if you experience any of these symptoms, as brain ischemia can cause permanent damage or death if left untreated.
