Head Injury

Community-service and law-enforcement authorities have taken a role in protecting potential victims and in prosecuting perpetrators. Most reports of abuse were submitted by educational personnel Other important advantages of the skeletal survey include a high sensitivity for most acute and healing fractures and a relatively low radiation burden. Geometric distortion and varying exposures are unacceptable limitations of this image. Use of a high-detail, high-contrast, screen-film system with good spatial resolution is mandatory. All abnormal areas should be viewed on at least 2 projections. Computed tomography CT scanning of the head is the imaging modality of choice for evaluating a child with acute neurologic findings or retinal hemorrhage on physical examination. It is more sensitive to acute intracerebral and extra-axial hemorrhages than is magnetic resonance imaging MRI. Brain MRI may be helpful as an adjunct for the evaluation of axonal shear injuries and for a precise dating of intracranial hemorrhage.

To systematically review the literature on dating subdural hematomas (SDHs) on CT and MRI scans. Methods We performed a systematic review in MEDLINE, EMBASE and Cochrane to search for articles that described the appearance of SDHs on CT or MRI in relation to time between trauma and scanning.

Hearing loss or hearing ringing tinnitus Blurred Vision Causes[ edit ] Subdural hematomas are most often caused by head injury , when rapidly changing velocities within the skull may stretch and tear small bridging veins. Subdural hematomas due to head injury are described as traumatic. Much more common than epidural hemorrhages , subdural hemorrhages generally result from shearing injuries due to various rotational or linear forces.

Subdural hematoma is also commonly seen in the elderly and in alcoholics, who have evidence of cerebral atrophy. Cerebral atrophy increases the length the bridging veins have to traverse between the two meningeal layers, hence increasing the likelihood of shearing forces causing a tear. It is also more common in patients on anticoagulants or antiplatelet drugs , such as warfarin and aspirin.

Patients on these medications can have a subdural hematoma after a relatively minor traumatic event.

Jul 01,  · Acute Subdural Haematoma (SDH) is the collection of blood between the dural and the arachnoid layers of the meninges. It is one of the most common types of intracranial mass lesion associated with high mortality and morbidity.

Facts about the brain: The brain contains around billion neurons. We have all our neurons when we are babies, but they aren’t yet connected as in an adult. Further, the brain is not fully myelinated until age years. This probably explains most developmental milestones, including those of Piaget. The brain has a great deal to do with our learning, thinking, mood, speech and behavior.

Tweet Pin After spending decades hosting a show requiring people to use their brains, Jeopardy host Alex Trebek is recovering from issues with his own. He is currently taking medical leave from the long-running game show to recover from surgery he had in mid-December to remove blood clots from his brain. Back in October, Trebek took a hard fall, hitting his head. This resulted in subdural hematoma, which caused the blood clots.

Apr 01,  · Currently, the dating of subdural haemorrhage by measuring the CT number alone could lead to inaccuracies as it depends on measurement technique, object composition, and beam energy.

The estimation of time since injury in cases of subdural haemorrhage has been studied only by a few investigators on the histological and radiological front. Materials and Methods The study included a total of cases of closed head injury with subdural haemorrhage. Results Statistically significant results were obtained between the HU measurements of the SDH and the post-traumatic intervals and were found to be statistically significant. A rough attempt was made to determine the effect of haematoma volume on attenuation and was found out to be statistically insignificant.

Conclusion The density of the subdural haematoma decreases with increase in the post-traumatic interval that concurs with the limited number of studies being conducted in the past. We concluded that further sorting of cases could be done according to its age with additional research and uniformity in the methodology. Attenuation coefficient, Computed tomography, Post-traumatic interval, Subdural haemorrhage, Volume Introduction Subdural Haemorrhage SDH is a form of brain haemorrhage in which there is a collection of blood between the dura and the arachnoid layers of the meninges.

Abstract Introduction Microscopic study of the organization of the Subdural Haemorrhage SDH verified against the time period can help us in the determination of its age which has serious medico-legal implications. Very few studies concerning the dating of SDH are present in the literature. Aim This study was conducted for dating the early subdural haemorrhage by routine histopathological stains. Materials and Methods A prospective analytical study was conducted during July to December

A subdural hematoma occurs when a vein ruptures between your skull and your brain’s surface. Acute subdural hematomas. If you sustain a major brain injury, this area can fill with blood and.

If symptoms are maximal at onset, the cause is more likely to be a subarachnoid hemorrhage or an embolic stroke. Causes Thrombotic stroke Illustration of an embolic stroke, showing a blockage lodged in a blood vessel. In thrombotic stroke, a thrombus [35] blood clot usually forms around atherosclerotic plaques. Since blockage of the artery is gradual, onset of symptomatic thrombotic strokes is slower than that of a hemorrhagic stroke. A thrombus itself even if it does not completely block the blood vessel can lead to an embolic stroke see below if the thrombus breaks off and travels in the bloodstream, at which point it is called an embolus.

Two types of thrombosis can cause stroke: Large vessel disease involves the common and internal carotid arteries , the vertebral artery , and the Circle of Willis. Small vessel disease involves the smaller arteries inside the brain: A stroke is the second leading cause of death in people under 20 with sickle-cell anemia. An embolus is most frequently a thrombus, but it can also be a number of other substances including fat e.

Thus, the source of the embolus must be identified. Because the embolic blockage is sudden in onset, symptoms usually are maximal at the start. Also, symptoms may be transient as the embolus is partially resorbed and moves to a different location or dissipates altogether. Emboli most commonly arise from the heart especially in atrial fibrillation but may originate from elsewhere in the arterial tree.

Physicians have an ethical and legal mandate to identify abused children so that they may be protected from further harm and are simultaneously required to think broadly and objectively about differential diagnoses. The medical literature is replete with examples of medical diseases that mimic abuse, potentially leading to misdiagnoses and subsequent harm to children and families. This review highlights some of the common and uncommon diseases that mimic physical and sexual abuse of children.

A subdural hematoma is a collection of blood between the covering of the brain (dura) and the surface of the brain. Causes A subdural hematoma is most often the result of a severe head injury.

Author Chris Meharg 2 Comments Head Injuries in Anime Part 2- Hematoma In part one of Head Injuries in Anime I explained how all those bumps on the head our favorite anime characters receive can be a lot more than just simple bruises, such as a variety of skull fractures. There are of course a number of head injuries beyond bruises and skull fractures, like hematoma and concussions, which have been in the news a lot over the last several years, due in part to the NFL and other collision sports.

Extra Science Content You might be wondering why I used the term collision sport instead of contact or full contact sport. This is because the American College of Pediatrics released a statement in that redefined their view of contact in sports. In contact sports eg, basketball and soccer , athletes routinely make contact with each other or inanimate objects but usually with less force than in collision sports.

In limited-contact sports eg, softball and squash , contact with other athletes or with inanimate objects is infrequent or inadvertent. Extra Science Content over If you are wondering what all of this has to do with anime, the answer is a lot. This knocked out state is often depicted with white pupil-less eyes or swirling eyes. There are many terms for this state: But before we get to concussions, there is one more head injury that is worthy of mention, even if its occurrence in anime is even less than a potential fractured skull.

A hematoma usually forms as a result of an impact or injury, but diseases can also cause them as well. How bruises form is fairly simple in that the blood vessel needs to break but the skin above the blood vessel does not; this means that the blood leaking from the blood vessel stays trapped inside the body. Real bruise bruise in anime You might be thinking what does all of this have to do with the brain?

Think about the last time you had a bruise and you might remember that a bruise and the swelling associated with it caused a bump in the area the bruise is located.

Dating of a subdural hematoma by visual inspection is unreliable, but histologically, using the Munro and Merritt chart, greater accuracy is possible. Although the Munro and Merritt dating concept was done from limited adult data, it is the most comprehensive study to date.

On the site, tallwomen. I did not say a short man. The reasons these women cite for their height preference are the same: Or from Jesus Christ, for that matter. She told me she felt protected by Christ. You might think she was nuts, but it illustrates a point beautifully: If your love interest must be taller, to make you feel protected and secure, to fulfill that fairy tale of the man being the protector, then this means the woman is unable to muster up her own self-assuredness. This is more evident when you consider that these tall women associate only height with protection.

I knew a man who was And where does the tall woman plan on going, that she needs a bodyguard, anyways? A woman could be with a man who fails to fight off the mugger.

Imaging in Subdural Hematoma

This article reviews the origin of this link and casts serious doubt on the specificity of the pathophysiologic connection. The forces required to cause brain injury were derived from an experiment of high velocity impacts on monkeys, that generated forces far above those which might occur with a shaking mechanism. These forces, if present, would invariably cause neck trauma, which is conspicuously absent in most babies allegedly injured by shaking.

Subdural hematoma may also be the result of common birth trauma, complicated by prenatal vitamin D deficiency, which also contributes to the appearance of long bone fractures commonly associated with child abuse. Retinal hemorrhage is a non-specific finding that occurs with many causes of increased intracranial pressure, including infection and hypoxic brain injury. The evidence challenging these connections should prompt emergency physicians and others who care for children to consider a broad differential diagnosis before settling on occult shaking as the de-facto cause.

The relationship of age to clinical and pathological findings was analyzed in adult patients operated on because of chronic subdural hematoma. A well-formed membrane on the inner and outer surface of the hematoma was used as the criterion for chronicity of the hematoma. Younger patients had.

Overview Overview Subdural hematomas SDH are 1 of the 3 types of extra-axial intracranial hemorrhages along with subarachnoid and epidural hemorrhages and usually occur as a result of trauma. Deceleration injuries are often the cause of subdural bleeding from rupturing of veins via a shearing mechanism. Other entities, such as child abuse and ventricular decompression, also can result in subdural bleeding, and spontaneous hemorrhages may occur in patients receiving anticoagulants or patients with a coagulopathy condition.

Compression of a dural sinus does not directly cause a subdural hematoma, although compression may result in a venous infarction. Chronic subdural hematoma is more common in elderly individuals because of the age-associated decrease in brain volume and the increase in venous fragility. Some hematomas can grow large enough to result in herniation of cerebral tissue.

Before computed tomography CT scanning and magnetic resonance imaging MRI technology, subdural hematomas were diagnosed only on the basis of this mass effect, which was depicted as displacement of the blood vessels on angiograms or as a calcified pituitary gland on skull radiographs. The advent of CT scan and MRI studies has made the diagnosis of even small hemorrhages routine see the image below. CSH images may appear as hypodense, isodense, hyperdense, or mixed density. Smaller hemorrhages may be missed on CT scans inn the nonacute setting, MRI is the study of choice because of its high sensitivity and specificity.
