...Mira LaVergne Mrs. Angie Herbert English II 14 March 2012 Chiari Malformation To say the human brain is complex is an understatement. Simply laughing requires help from five different areas of the brain. Nursing Assistant Central 4. Dr. Choug Bui’s procedure for Chiari Malformation is better because he uses the body’s own tissue instead of synthetic materiel. In the normal brain Attached to the brain stem is the cerebellum. It looks a lot like a cauliflower. The cerebellum controls movement and balance. It is important with the coordation of the body and the body’s equilibrium. The brain stem starts out at brain and continues throughout the body’s spine; which advent ally turns into the spinal cord. The brain stem is what makes the body alive. Its sends signals throughout the body, most importantly to the body’s main organs. It also regulates the body’s consciousness. The spine contains 26 bones, 24 are vertebrates. Vertebrates are the main part of the spine. The spine is divided into 5 parts: cervical, thoracic, lumbar, sacrum, and coccyx. When compared to the normal human brain, the Chiari Malformation is clearly different. This Malformation was discovered by Hans Chiari in 1819. Hewitt and Gabata 4. It is a rare, but serious neurological condition. Labuda 20. Chiari Malformation is where the cerebellum descends out into the spinal canal. Labuda 20. It is a progressive condition.

(Hom, 2009) Bacterial meningitis more frequently occurs in black and Hispanic children. This is thought to be related to socioeconomic rather than racial factors The brain and spinal cord are remarkably resistant to infection, but when they become infected, the consequences are usually very serious. Infections may be caused by bacteria, viruses, fungi, and occasionally protozoa or parasites. The most common type of CNS infection is Bacterial Meningitis which is characterized by inflammation of the meninges, the membranes lining the brain and spinal cord. (Hom, 2009. Almost any bacteria entering the body can cause meningitis. The most common are meningococci (Neisseria meningitidis), pneumococci (Streptococcus pneumonia), and Haemophilus influenza. Thtese organisms are often present in the nasopharynx. S. pneumonia and N. meningitides are found most often in adults. Factors predisposing to bacterial meningitis include any circumstance where the dura has been compromised, such as open brian injry or brain surgery, systemic infection, anatomic defects of the skull, immunocompromise, and other systemic illnesses. Close quarters, poor hygiene, and malnutrition also place people at risk. THE BRAIN HAS 3 PROTECTIVE...

...confusion. Mr. Drake had a physical examination done and he is suffering (encephalitis) inflammation of the brain tissue. Mr. Drake was given fluids through the IV to treat the infection around the brain tissue. Mr. Drake was placed on medication through the IV. Because of the severeness of his illness, Mr. Drake went into a light comatose state which only allowed tactile and verbal stimuli (response), but was unconscious. So a tube was placed through the nostril for feeding purposes. After 14 days of fluid injection through the IV Mr. Drake was slowly back to normal. PART 2. 1. Meningitis is swelling of the membranes around the brain and spinal cord. There are different types of meningitis, but most are caused by viruses or bacteria. Viral meningitis can make you very sick but it often doesn’t have lingering effects. Bacterial meningitis is more serious. It progresses rapidly and can cause permanent damage or even become life-threatening. CT scans of the head may reveal swelling or inflammation. These tests can also help your doctor look for infection in other areas of the body that may be associated with meningitis. Spinal tap (lumbar puncture). The definitive diagnosis of meningitis requires an analysis of your cerebrospinal fluid (CSF), which is collected during a procedure known as a spinal tap. In people with meningitis, the CSF fluid often shows a low sugar (glucose) level along with an increased white blood cell count and increased protein. CSF analysis may also help your...

...partition of circulating blood from the brain extracellular fluid in the central nervous system. It arises along all the capillaries and comprises of tight junctions close to capillaries which is not present in normal circulation. The blood–brain barrier is composed of high-density cells restricting passage of substances from the bloodstream much more than endothelial cells in capillaries elsewhere in the body. Astrocyte cell projections called astrocytic feet (also known as glia limitans) surround the endothelial cells of the blood–brain barrier, offering biochemical aid to those cells. The blood–brain barrier is different from the pretty similar blood–cerebrospinal-fluid barrier, which is a role of the choroidal cells of the choroid plexus, and from the blood–retinal barrier, which can be believed to be a part of the entire dominion of such barriers. Numerous regions of the human brain are not on the brain side of the blood–brain barrier. These comprise circumventricular organs. Example include: the top of the third and fourth ventricles; capillaries in pineal gland on the roof of diencephalon and pineal gland. The pineal gland secretes the hormone melatonin "directly into the systemic circulation". Therefore, melatonin is not affected by the blood–brain barrier. The blood–brain barrier works very efficiently to defend the brain from numerous common bacterial infections, infections of the brain rare. Infections of the brain occur are very serious and difficult to treat. Antibodies...

...and produce clinical symptoms due to mass effect or obstructive hydrocephalus. The mechanism of progressive enlargement of arachnoid cysts is controversial. A one-way slit or ball valve is often hypothesized as the mechanism responsible for enlargement. Clinical Presentation: We present four cases of communicating congenital suprasellar prepontine arachnoid cysts in which a slit-valve was identified in the wall of the cyst. All four patients presented with hydrocephalus due to enlargement of the arachnoid cyst. The slit valve was located in the arachnoid wall of each arachnoid cyst and was located in the midline directly over the main trunk of the basilar artery. We believe this slit valve was responsible for the net influx of cerebrospinal fluid (CSF) into the cyst and thus responsible for cyst enlargement over time. We also present one case of an arachnoid cyst in the middle cranial fossa that had a small circular opening in the wall of the cyst but lacked a slit-valve. This cyst did not enlarge and required surgery because of cyst wall rupture and the development of a subdural hygroma with headaches. Conclusion: One-way slit-valves exist and are the mechanism of enlargement of suprasellar prepontine arachnoid cysts. The location of the slit valve opening in each of our arachnoid cyst cases was directly over the basilar artery trunk. Caudal to rostral CSF flow in the prepontine cistern during the cardiac cycle lifted the arachnoid wall of the cyst off the basilar trunk...

Myelitis – inflammation of the spinal cord Arthritis is inflammation of the joint and it is used in a medical environment every day. Let’s say a 70 year old comes in with knee pain her knees are swelling and pain that she can barely walk. The doctor will ask a series of question then he would start to run testes like draw fluid from the knee and do x-rays to see what type of arthritis the patient have. Your regular doctor may use the term arthritis because they can give the patient medicine for inflammation and pain if the pain persist (U.S. National Library of Medicine - The World's Largest Medical Library, 2012) the patient will have to see a specialist. Meningitis is inflammation of the membrane covering the brain and spinal cord it is used in a medical environment rarely. If a 5 year old comes to the doctor with symptoms like vomiting, headache, and neck stiffness the doctor will ask question how long have she had these symptoms and run testes like cerebrospinal fluid, check the brain, and C- reactive protein to see what kind of meningitis it is. The hospital use the term meningitis or the patient primary doctor if the patient need further testing they will recommend a specialist. Myelitis is inflammation of the spinal cord.

...The day that changed my life It was a phone call from the hospital in S.C to my mom back in MI that changed my life forever. I was 18 years old newly married, traveling around the states with my husband for his job I was in Greenville, S.C. when one of my usual migraines started. Migraines have been a part of my life since the age of 12 so this was not out of the ordinary, until day 3 and no change. We knew something had to be wrong and that’s when the journey to where I am today started. I went to the emergency room to get a Toradol shot as I had before, I explained the situation and the length of the migraine and that when the nurse felt something was more serious than a migraine. I was rushed to the back for an MRI and that when it was seen I had a quarter sized tumor in the center of my brain. They were sending me over to a neurosurgeon to talk about immediate brain surgery the tumor needed to be removed before any further damage was done. I was only a kid all alone with just my husband in a state that we didn’t know a single person and I was being prepped for an overnight stay in the hospital while having to break the news to my mom over the phone. I was admitted at 11 pm and was scheduled to have the surgery at 5 am, after a sleepless night and the hours slowly passing 5 am came and was gone and I had yet to see a nurse or a doctor. A few more hours passed and finally at 3 pm I saw the neurosurgeon who advised that he was releasing me and that he would not be performing...

...Hydrocephalus Hydrocephalus Hydrocephalus is an anomaly which origins have been linked to both genetic and environmental factors. Saladin, (2007) has defined hydrocephalus as an abnormal accumulation of central spinal fluid (CSF) in the brain usually as a result of a blockage in the CSF flow and the subsequent reabsorption. The rate of occurrence of hydrocephalus varies by whom is asked; there are not any national registries therefore there is not a data base that can accurately depict a real number of people afflicted with this anomaly. Instances of hydrocephalus are not all associated with genetics, some other factors that have been documented are: congenital malformations, intercerebral hemorrhage, infection and maternal alcohol abuse. Two article will be discussed in the paper; one article is dedicated to genetics while the second article discusses environmental factors that have been associated with hydrocephalus. Article 1 Genetics of human hydrocephalus The article discusses that evidence is mounting that genetic factors play a role in the “pathogenesis of hydrocephalus”. Hydrocephalus has two forms; acquired and inherited. There are several documented instanced of genetic involved in hydrocephalus in animals, but the documentation that has been gathered to date is not as substantial in human hydrocephalus. “Hydrocephalus is considered complex and has multifactorial neurological defects.” It is believed that one of the possible causes is related to protein and...

The case study starts with a description of a patients’ medical history, followed by discussion question/s. First, you have to analyze the medical history of the patient. As you read the patient’s information: * Highlight any risk factors that might exist, existing medical conditions, present signs and symptoms or complains that the patient is suffering from. * Analyze the results of any diagnostic tests that were performed. Diagnostic tests include, physical exams, blood test, radiologic tests (x-ray, CT scans, etc.), and other functional tests. * Relate the medical treatment used to the underlying pathology. * Propose clinical management plan for the patient’s condition, and possible prognosis. You are encouraged to discuss the cases with other students and in groups, however, each student should submit the analysis of the case study in their own words through discussions. Students should submit their case study through the “Discussion” link AND the “Turnitin Dropbox” link for that case study available on the course’s main page. If you fail to submit your case study through both links your case study will not be graded. Turnitin is an automated system which instructors can use to quickly and easily compare each student's assignment with billions of web sites, as well as an enormous database of student papers that grows with each submission.Accordingly, you...

...Bacterial Meningitis Meningitis is a bacterial infection of the membranes covering the brain and spinal cord (meninges). Meningitis can be acute, with a quick onset of symptoms, it can be chronic, and lasting a month or more, or it can be mild or aseptic. Acute bacterial meningitis is the most common form of meningitis.Meningitis is a disease that can be passed from person to person (contagious). It is caused most often by viruses or bacteria that infect the tissues, meninges and sometimes the fluid (cerebral spinal fluid, or CSF) that surround the brain and spinal cord. Organisms that cause meningitis can be passed from one person to another or passed from rodents and insects to people. But exposure to an organism that causes meningitis does not mean you will get the infection. During birth, a mother can pass organisms that cause meningitis to her baby even if the mother does not have symptoms. Delivering a baby by cesarean section rather than through the birth canal does not always protect the baby from getting the infection. Both bacteria and viruses can be transmitted this way. Through stool, stool could have enteroviruses or certain types of bacteria in it. Washing hands on a regular basis can help prevent you and your children from getting infected this way. More children than adults get meningitis this way. Through coughing and sneezing. Infected people can pass certain bacteria that are normally found in saliva or mucus in their noses and throats. Through kissing...
