Abstract:
Spontaneous spinal epidural haematoma (SSEH) is a rare condition that requires urgent surgical intervention in order to prevent permanent neurological deficit. SSEH commonly presents as a paraparesis or tetraparesis. SSEH presenting as a hemiparesis is less common and in such situations, it can be mistaken for a cerebrovascular accident (CVA). Thrombolytic or anticoagulant treatment for CVA can potentially worsen the neurological deficit. We report one such case of SSEH misdiagnosed as a CVA. Treatment with tissue plasminogen activator led to worsening of his condition. On a subsequent cervical spine MRI, an epidural haematoma extending from C3 to C5 was detected and treated with laminectomy and evacuation. Surgical intervention led to significant improvement from American Spinal Injury Association Scale (ASIA) B to ASIA E. Presence of clinical features such as Horner's syndrome, Brown-Sequard syndrome and the absence of cranial nerve palsies in acute hemiparesis are indicative of SSEH rather than CVA.

Cell Potential and Free Energy
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Potential Energy
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...
