SCI Mechanism and Pathophysiology

The potentially devastating consequences of SCI can include major dysfunction to the motor sensory and autonomic systems Appropriate pre hospital management and consideration of the mechanism of injury can significantly improve outcomes in patients with SCI Mechanism and Pathophysiology SCI is usually caused when two or more vertebrae have an unstable fracture but can also be caused by ruptured ligaments allowing movement of the vertebra to damage the spinal cord without an actual fracture Marsland and Kapoor 2008 127 Blunt trauma to the head and neck is the most common cause of fracture or ligament rupture 50 80 of SCI result from a hyperflexion rotation injury Cole 2009 SCI can occur both in isolation or with other injuries Hess et al 2016 However it only presents in 2 6 of trauma patients although this figure doubles in patients with a head injury and trebles in those with decreased level of consciousness Milby et al 2008 Halpern et al 2010 

A SCI can be complete or incomplete In a complete spinal injury sensation and motor function below the point of injury are lost whether or not the spinal cord is severed Bledsoe and Benner 2006 394 In an incomplete SCI full or partial motor or sensory function are preserved below the level of injury Wyatt et al 2012 369 A patient's level of injury is defined as the lowest level of full sensation and function Greaves and Porter 2007 282 Paraplegia occurs when the legs are affected by spinal cord damage in thoracic lumbar or sacral injuries and tetraplegia occurs when all four limbs are affected as a direct result of cervical spine damage Douglas et al 2013 260 As spinal nerve tissue is very similar to brain tissue the nature of injuries are comparable Spinal nerve tissue can be concussed bruised and suffer cell death It can also be subject to compression and swelling Bledsloe and Benner 2006 394 Serious SCI result in a high percentage of permanent damage with poor outcomes for the patient's quality of life Dixon et al 2014

Creation of the Periodic Table

Have you ever wondered about the creation of the periodic table Over the years the Periodic Table has been through lots of changes As much as it changes the people who make add details and elements to the table change as well The elements of the Periodic Table shape the table in how it looks and the overall organization of it really brings the whole table together In my easy you will learn about a Russian Chemist and his amazing creation of the periodic table Dmitri Ivanovich Mendeleev is a Russian Chemist and Inventor He was born in Tobolsk Russia on Feb 8 1834 and died on Feb 2 1907 in St Petersburg Russia right before his 73rd birthday Mendeleev is the youngest child in his family out of 14 children Although Mendeleev was very smart his family went through pretty harsh times After his father went blind his mom reopened a glass factory But directly after that his dad died when Mendeleev was 13 because of Tuberculosis But it didn t stop there His mom s glass factory burnt down and she lost everything Mendeleev went through school like it was no problem and graduated at age 16 Mendeleev s brother in law talked about science and chemistry a lot so Mendeleev took fond of chemistry He went to St Petersburg Russia in 1861 to become a professor in chemistry at the University of St Petersburg An Italian chemist Stanislao Cannizzaro collected data from labs all over the world and created a pamphlet The pamphlet include ways to determine a consistent set of atomic weights and that there are weight for each element Cannizzaro held a meeting about the pamphlet and Mendeleev attended Mendeleev found out by looking at the pamphlet that he can arrange the elements by their atomic weights and their properties This was how he constructed the table The Periodic Table Mendeleev believed in his Periodic Table so he changed the atomic mass of the elements so they would fit on the table As for example Beryllium Be which was placed in Group 15 but got moved to Group Two next to Magnesium Mg because they were more closely related
