| ARTICLES RELATED TO biochemical cascade | | | |  biochemical cascade: Encyclopedia - Traumatic brain injuryTraumatic brain injury (TBI), traumatic injuries to the brain, also called acquired brain injury, intracranial injury, or simply head injury, occurs when a sudden trauma causes damage to the brain. Parts of the brain that can be damaged include the cerebral hemispheres, cerebellum, and brain stem (see brain damage). Symptoms of a TBI can be mild, moderate, or severe, depending on the extent of the damage to the brain. Outcome can be anything from complete recovery to permanent disability or death.

| | | | biochemical cascade: Encyclopedia II - Subdural hematoma - Signs and symptoms Symptoms of subdural hemorrhage have a slower onset than those of epidural hemorrhages because the lower pressure veins bleed more slowly than arteries. Thus, signs and symptoms may show up within 24 hours but can be delayed as much as 2 weeks (Sanders and McKenna, 2001). If the bleeds are large enough to put pressure on the brain, signs of increased ICP or damage to part of the brain will be present (Wagner, 2004).
Other signs and symptoms of subdural hematoma include the following:

| | | | biochemical cascade: Encyclopedia II - Complement system - Outline The three pathways all generate homologous variants of the protease, C3-convertase. C3-convertase cleaves and activates C3, creating C3a and C3b and causing a cascade of further cleavage and activation events. C3b binds to the surface of pathogens leading to greater internalization by phagocytic cells. C5a is an important chemokine, which leads to the recruitment of inflammatory cells. C5b is initiates the membrane attack pathway which results in the membrane attack complex (MAC), consisting of C5b, C6, C7, C8, and polymeric C9. MAC is the cytolytic endproduct of the complement cascade, it forms a transmembrane channel w ...

| | | | biochemical cascade: Encyclopedia II - Stroke - Treatment
Stroke - Early assessment.
It is important to identify a stroke as early as possible because patients who are treated earlier are more likely to survive and have better recoveries.
If a patient is suspected of having a stroke, emergency services should be contacted immediately. The patient should be transported to the nearest hospital that can provide a rapid evaluation and treatment with the latest available therapies targeted to the type of stroke. The faster these therapies are started for hemorrhagic a ...

| | | | biochemical cascade: Encyclopedia II - Traumatic brain injury - Complications Sometimes, health complications occur in the period immediately following a TBI. These complications are not types of TBI, but are distinct medical problems that arise as a result of the injury. Although complications are rare, the risk increases with the severity of the trauma. Complications of TBI include immediate seizures, hydrocephalus or post-traumatic ventricular enlargement, cerebrospinal fluid leaks, infections, vascular injuries, cranial nerve injuries, pain, bed sores, multiple organ system failure in unconscious patients, and polytrauma (trau ...

| | | | biochemical cascade: Encyclopedia II - Subdural hematoma - Features Most of the time, subdural hematomas occur around the tops and sides of the frontal and parietal lobes (University of Vermont; Wagner, 2004). They also occur in the posterior fossa, and near the falx cerebri and tentorium (Wagner, 2004). Unlike epidural hematomas, which cannot expand past the sutures of the skull, subdural hematomas can expand along the inside of the skull, creating a convex shape that follows the curve of the brain, stopping only at the dural re ...

| | | | biochemical cascade: Encyclopedia II - Subdural hematoma - Subtypes Subdural hematomas are divided into acute, subacute, and chronic, depending on their speed of onset. Acute subdural hematomas that are due to trauma are the most lethal of all head injuries and have a high mortality rate if they are not rapidly treated with surgical decompression.
Acute bleeds develop after high speed acceleration or deceleration injuries and are increasingly severe with larger hematomas. They are most severe if associated with cerebral contusions (Wagner, 2004). Though much faster than chronic subdural bleeds, acute ...

| | | | biochemical cascade: Encyclopedia II - Traumatic brain injury - Causes of and Risk Factors for TBI Half of all TBIs are due to transportation accidents involving automobiles, motorcycles, bicycles, and pedestrians. These accidents are the major cause of TBI in people under age 75.
For those 75 and older, falls cause the majority of TBIs.
Approximately 20 percent of TBIs are due to violence, such as firearm assaults and child abuse, and about 3 percent are due to sports injuries. Fully half of TBI incidents involve alcohol use.

| | | | biochemical cascade: Encyclopedia II - Traumatic brain injury - Types of TBI The damage from TBI can be focal, confined to one area of the brain, or diffuse, involving more than one area of the brain. Diffuse trauma to the brain is frequently associated with concussion (a shaking of the brain in response to sudden motion of the head), diffuse axonal injury, or coma. Localized injuries may be associated with neurobehavioral manifestations, hemiparesis or other focal neurologic deficits.
Types of focal brain injury include bruising of brain tissue called a contusion and intracranial hemorrhage or hematoma, heavy ...

| | | | biochemical cascade: Encyclopedia II - Traumatic brain injury - Effects on consciousness Generally, there are five abnormal states of consciousness that can result from a TBI: stupor, coma, persistent vegetative state, locked-in syndrome, and brain death.
Stupor is a state in which the patient is unresponsive but can be aroused briefly by a strong stimulus, such as sharp pain. Coma is a state in which the patient is totally unconscious, unresponsive, unaware, and unarousable.
Patients in a persistent vegetative state are unconscious and unaware of their surroundings, but they continue to have a sleep-wake cycle and ...

| | | | biochemical cascade: Encyclopedia II - Subdural hematoma - Pathophysiology Collected blood from the subdural bleed may draw in water due to osmosis, causing it to expand, which may compress brain tissue and cause new bleeds by tearing other blood vessels (Downie, 2001). The collected blood may even develop its own membrane (McCaffrey, 2001).
In some subdural bleeds, the arachnoid layer of the meninges is torn, and cerebrospinal fluid (CSF) and blood both expand in the intracrania ...

| | | | biochemical cascade: Encyclopedia II - Subdural hematoma - Treatment It is important that a patient receive medical assessment, including a complete neurological examination, after any head trauma. A CT scan or MRI scan will usually detect significant subdural hematomas.
Treatment of a subdural hematoma depends on its size and rate of growth. Small subdural hematomas can be managed by careful monitoring until the body heals itself. Large or symptomatic hematomas require a craniotomy, the surgical opening of the skull. A surgeon then opens the dura, removes the blood clot with suction or irrigation, and ...

With mild TBI, the patient may remain conscious or may lose consciousness for a few seconds or minutes. The person may also feel dazed or not like him- or herself for several days or weeks after the initial injury. Other symptoms include:
headache,
mental confusion,
lightheadedness,
dizziness,
double vision, blurred vision, or tired eyes,

| | | | biochemical cascade: Encyclopedia II - Stroke - Prevention Prevention is an important public health concern. Identification of patients with treatable risk factors for stroke is paramount. Treatment of risk factors in patients who have already had strokes (secondary prevention) is also very important as they are at high risk of subsequent events compared with those who have never had a stroke. Medication or drug therapy is the most common method of stroke prevention. Aspirin (usually at a low dose of 75 mg) is recommended for the primary and secondary prevention of stroke, and treating hypertension is another way to mo ...

| | | | biochemical cascade: Encyclopedia II - Subdural hematoma - Risk factors Factors increasing the risk of a subdural hematoma include very young or very old age. As the brain shrinks with age, the subdural space enlarges and the veins that traverse the space must travel over a wider distance, making them more vulnerable to tears. This and the fact that the elderly have more brittle veins make chronic subdural bleeds more common in older patients (Downie, 2001). Infants, too, have larger subdural spaces and are more predisposed to subdural bleeds than are young adults (Wagner, 2004).
Other risk factors for subdural bleeds include taking blood thinners (antic ...
