Cerebral Venous Sinus Thrombosis
Cerebral Venous Sinus Thrombosis samer kareem 5,812 Views • 2 years ago

Thrombosis of the venous channels in the brain is an uncommon cause of cerebral infarction relative to arterial disease, but it is an important consideration because of its potential morbidity. (See Prognosis.) Knowledge of the anatomy of the venous system is essential in evaluating patients with cerebral venous thrombosis (CVT), since symptoms associated with the condition are related to the area of thrombosis. For example, cerebral infarction may occur with cortical vein or sagittal sinus thrombosis secondary to tissue congestion with obstruction. (See Presentation.) Lateral sinus thrombosis may be associated with headache and a pseudotumor cerebri–like picture. Extension into the jugular bulb may cause jugular foramen syndrome, while cranial nerve palsies may be seen in cavernous sinus thrombosis as a compressive phenomenon. Cerebral hemorrhage also may be a presenting feature in patients with venous sinus thrombosis. (See Presentation.) Imaging procedures have led to easier recognition of venous sinus thrombosis (see the images below), offering the opportunity for early therapeutic measures. (See Workup.)

View Media Gallery The following guidelines for CVT have been provided by the American Heart Association and the American Stroke Association [1] : In patients with suspected CVT, routine blood studies consisting of a complete blood count, chemistry panel, prothrombin time, and activated partial thromboplastin time should be performed. Screening for potential prothrombotic conditions that may predispose a person to CVT (eg, use of contraceptives, underlying inflammatory disease, infectious process) is recommended in the initial clinical assessment. Testing for prothrombotic conditions (including protein C, protein S, or antithrombin deficiency), antiphospholipid syndrome, prothrombin G20210A mutation, and factor V Leiden can be beneficial for the management of patients with CVT. Testing for protein C, protein S, and antithrombin deficiency is generally indicated 2-4 weeks after completion of anticoagulation. There is a very limited value of testing in the acute setting or in patients taking warfarin. In patients with provoked CVT (associated with a transient risk factor), vitamin K antagonists may be continued for 3-6 months, with a target international normalized ratio of 2.0-3.0. In patients with unprovoked CVT, vitamin K antagonists may be continued for 6-12 months, with a target international normalized ratio of 2.0-3.0. For patients with recurrent CVT, venous thromboembolism (VTE) after CVT, or first CVT with severe thrombophilia (ie, homozygous prothrombin G20210A; homozygous factor V Leiden; deficiencies of protein C, protein S, or antithrombin; combined thrombophilia defects; or antiphospholipid syndrome), indefinite anticoagulation may be considered, with a target international normalized ratio of 2.0-3.0. For women with CVT during pregnancy, low-molecular-weight heparin (LMWH) in full anticoagulant doses should be continued throughout pregnancy, and LMWH or vitamin K antagonist with a target international normalized ratio of 2.0-3.0 should be continued for ≥6 weeks postpartum (for a total minimum duration of therapy of 6 months). It is reasonable to advise women with a history of CVT that future pregnancy is not contraindicated. Further investigations regarding the underlying cause and a formal consultation with a hematologist or maternal fetal medicine specialist are reasonable. It is reasonable to treat acute CVT during pregnancy with full-dose LMWH rather than unfractionated heparin. For women with a history of CVT, prophylaxis with LMWH during future pregnancies and the postpartum period is reasonable.

Lumbar Epidural Abscess
Lumbar Epidural Abscess samer kareem 10,986 Views • 2 years ago

An epidural abscess is a collection of pus (infected material) between the outer covering of the brain and spinal cord and the bones of the skull or spine. The abscess causes swelling in the area. Spinal cord abscess (SCA) is a rare condition capable of causing permanent damage to the spinal cord. Abscesses are caused when injured tissue becomes infected. The body's immune system sends white blood cells to help fight off the infection. They begin to fill the damaged tissue, causing pus to build up.

Obstructive lung diseases include conditions that make it hard to exhale all the air in the lungs. People with restrictive lung disease have difficulty fully expanding their lungs with air. Obstructive and restrictive lung disease share the same main symptom: shortness of breath with exertion.

Progeria
Progeria samer kareem 5,469 Views • 2 years ago

Progeria (pro-JEER-e-uh), also known as Hutchinson-Gilford syndrome, is an extremely rare, progressive genetic disorder that causes children to age rapidly, beginning in their first two years of life. Children with progeria generally appear normal at birth. During the first year, signs and symptoms, such as slow growth and hair loss, begin to appear. Heart problems or strokes are the eventual cause of death in most children with progeria. The average life expectancy for a child with progeria is about 13 years, but some with the disease die younger and some live 20 years or longer. There's no cure for progeria, but ongoing research shows some promise for treatment.

Scoliosis Fusion  Surgery
Scoliosis Fusion Surgery samer kareem 25,069 Views • 2 years ago

In as many as 80% of cases, doctors don’t find the exact reason for a curved spine. Scoliosis without a known cause is what doctors call “idiopathic.” Some kinds of scoliosis do have clear causes. Doctors divide those curves into two types -- structural and nonstructural. In nonstructural scoliosis, the spine works normally, but looks curved. Why does this happen? There are a number of reasons, such as one leg’s being longer than the other, muscle spasms, and inflammations like appendicitis. When these problems are treated, this type of scoliosis often goes away.

This 40 yr male had upper abdominal pain for 3 months. A video-endoscopic examination of esophagus, stomach and duodenum was performed. A large 2.5x2.5 cm chronic ulcer was detected in the first part (bulb) of duodenum. A gastric biopsy was taken for diagnosis of Helicobacter infection and a rapid urease test done which was positive. He received triple therapy (2 antibiotics and acid suppressive drug for one week) to eradicate Helicobacter pylori infection. Ulcer disease showed rapid clinical and endoscopic healing. Eradication of Helicobacter pylori infection led to permanent ulcer cure.

Bilateral Sagittal Split osteotomy
Bilateral Sagittal Split osteotomy samer kareem 10,727 Views • 2 years ago

The bilateral sagittal split osteotomy is an indispensable tool in the correction of dentofacial abnormalities. The technique has been in practice since the late 1800s, but did not reach widespread acceptance and use until several modifications were described in the 1960s and 1970s. Those modifications came from a desire to make the procedure safer, more reliable, and more predictable with less relapse. Those goals continue to stimulate innovation in the field today and have helped the procedure evolve to be a very dependable, consistent method of correction of many types of malocclusion. The operative surgeon should be well versed in the history, anatomy, technical aspects, and complications of the bilateral sagittal split osteotomy to fully understand the procedure and to counsel the patient.

What Is Phonemic Awareness, Reading Program For Kids, Phonics For Children, Teach Your Baby To Read---- http://children-learning-reading.good-info.co----- What is Phonemic Awareness, Phonemic Awareness is defined as the ability to identify, hear, and work with the smallest units of sound known as phonemes. It is NOT the same as phonological awareness, instead, it is a sub-category of phonological awareness. For example, phonemic awareness is narrow, and deals only with phonemes and manipulating the individual sounds of words - such as /c/, /a/, and /t/ are the individual sounds that make up to form the word "cat". Phonological awareness on the other hand, includes the phonemic awareness ability, and it also includes the ability to hear, identify, and manipulate larger units of sound such as rimes and onsets. Phonemic awareness can be taught very early on, and will play a critical role in helping children learn to read and spell. While it's not set in stone on when a child can learn to read, however, I do believe that a child that can speak is a child that can learn to read. Children as young as two years old can learn to read by developing phonemic awareness, and they can learn to read fluently. Please see a video of a 2 year old (2yr11months) reading below. Below are several of the most common phonemic awareness skills that are often practiced with students and young children: Phonemic identity - being able to recognize common sounds in different words such as /p/ is the common sound for "pat", "pick", and "play". Phonemic isolation - being able to recognize the individual sounds of words such as /c/ is the beginning sound of "cat" and /t/ is the ending sound of "cat". Phoneme substitution - being able to change one word to another by substituting one phoneme. For example changing the /t/ in "cat" to /p/ now makes "cap". Word Segmenting - the parent says the word "lap", and the child says the individual sounds: /l/, /a/, and /p/. Oral blending - the parent says the individual sounds such as /r/, /e/, and /d/, and the child forms the word from the sounds to say "red". Studies have found that phonemic awareness is the best predictor of reading success in young children. Research has also found that children with a high level of phonemic awareness progress with high reading and spelling achievements; however, some children with low phonemic awareness experience difficulties in learning to read and spell. Therefore, it is important for parents to help their young children develop good phonemic awareness. Being able to oral blend and segment words helps children to read and spell. According to the National Reading Panel, oral blending helps children develop reading skills where printed letters are turned into sounds which combine to form words. Additionally, word segmenting helps children breakdown words into their individual sounds (phonemes), and helps children learn to spell unfamiliar words. As a young child begins to develop and master phonemic awareness skills, they will discover an entirely new world in print and reading. You will open up their world to a whole new dimension of fun and silliness. They will be able to read books that they enjoy, develop a better understanding of the world around them through printed materials, and have a whole lot of fun by making up new nonsense words through phonemic substitutions. For example, we taught our daughter to read at a young age - when she was a little over 2 and a half years old. Before she turned three, she would run around the house saying all types of silly words using phonemic substitution. One of her favorite was substituting the letter sound /d/ in "daddy" with the letter sound /n/. So, she would run around me in circles and repeatedly say "nanny, nanny, come do this" or "nanny, nanny, come play with me" etc... Of course, she only did this when she wanted to be silly and to make me laugh, at other times, she would of course properly refer to me as "daddy", and not "nanny". She is well aware of the differences between these words and is fully capable of using phonemic substitution to change any of the letters in the words to make other words. Give your child a head start, and.. pave the way for a bright, successful future..Click here to learn how to easily and quickly teach your child to read. http://children-learning-reading.good-info.co

Rickets
Rickets samer kareem 1,389 Views • 2 years ago

Rickets is the softening and weakening of bones in children, usually because of an extreme and prolonged vitamin D deficiency. Vitamin D promotes the absorption of calcium and phosphorus from the gastrointestinal tract. A deficiency of vitamin D makes it difficult to maintain proper calcium and phosphorus levels in bones, which can cause rickets. Adding vitamin D or calcium to the diet generally corrects the bone problems associated with rickets. When rickets are due to another underlying medical problem, your child may need additional medications or other treatment. Some skeletal deformities caused by rickets may require corrective surgery.

What is Major Depressive Disorder?
What is Major Depressive Disorder? samer kareem 2,063 Views • 2 years ago

Possible causes include a combination of biological, psychological, and social sources of distress. Increasingly, research suggests these factors may cause changes in brain function, including altered activity of certain neural circuits in the brain. The persistent feeling of sadness or loss of interest that characterizes major depression can lead to a range of behavioral and physical symptoms. These may include changes in sleep, appetite, energy level, concentration, daily behavior, or self-esteem. Depression can also be associated with thoughts of suicide. The mainstay of treatment is usually medication, talk therapy, or a combination of the two. Increasingly, research suggests these treatments may normalize brain changes associated with depression.

Traumatic Acute Subdural Hematoma
Traumatic Acute Subdural Hematoma Surgeon 7,087 Views • 2 years ago

A subdural hematoma (SDH) is a collection of blood below the inner layer of the dura but external to the brain and arachnoid membrane (see the images below). Subdural hematoma is the most common type of traumatic intracranial mass lesion. Subdural hematoma occurs not only in patients with severe head injury but also in patients with less severe head injuries, particularly those who are elderly or who are receiving anticoagulants. Subdural hematoma may also be spontaneous or caused by a procedure, such as a lumbar puncture (see Etiology). Rates of mortality and morbidity can be high, even with the best medical and neurosurgical care (see Prognosis). Subdural hematomas are usually characterized on the basis of their size and location and the amount of time elapsed since the inciting event age (ie, whether they are acute, subacute, or chronic). When the inciting event is unknown, the appearance of the hematoma on neuroimaging studies can help determine when the hematoma occurred. These factors, as well as the neurologic and medical condition of the patient, determine the course of treatment and may also influence the outcome. Generally, acute subdural hematomas are less than 72 hours old and are hyperdense compared with the brain on computed tomography scans. The subacute phase begins 3-7 days after acute injury. Chronic subdural hematomas develop over the course of weeks and are hypodense compared with the brain. However, subdural hematomas may be mixed in nature, such as when acute bleeding has occurred into a chronic subdural hematoma. Presentation varies widely in acute subdural hematoma (see Clinical). Many of these patients are comatose on admission. However, approximately 50% of patients with head injuries who require emergency neurosurgery present with head injuries that are classified as moderate or mild (Glasgow Coma Scale scores 9-13 and 14-15, respectively). Many of these patients harbor intracranial mass lesions. In a large series of patients who developed intracranial hematomas requiring emergent decompression, more than half had lucid intervals and were able to make conversation between the time of their injury and subsequent deterioration. In a more comprehensive review of the literature on the surgical treatment of acute subdural hematomas, lucid intervals were noted in up to 38% of cases. These patients may be more likely to benefit from medical and surgical intervention when instituted in a timely fashion (ie, before further neurological deterioration).

Esophageal Varices
Esophageal Varices samer kareem 2,309 Views • 2 years ago

Esophageal varices are abnormal, enlarged veins in the tube that connects the throat and stomach (esophagus). This condition occurs most often in people with serious liver diseases. Esophageal varices develop when normal blood flow to the liver is blocked by a clot or scar tissue in the liver. To go around the blockages, blood flows into smaller blood vessels that aren't designed to carry large volumes of blood. The vessels can leak blood or even rupture, causing life-threatening bleeding. A number of drugs and medical procedures can help prevent and stop bleeding from esophageal varices.
