Spinal Epidural Hematoma

High pressure decreases the perfusion pressure in brain blood vessels (since the perfusion pressure is the mean arterial pressure minus the intracranial pressure). [dartmouth.edu]

If this is too low, there will be further damage to neural tissue due to ischemia, which will result in further edema and an even greater increase in pressure. [dartmouth.edu]

Hypovolemia

Intact cerebral blood flow (CBF) is essential for cerebral metabolism and function, whereas hypoperfusion in relation to hypovolemia and hypocapnia can lead to severe cerebral damage. This study was designed to assess internal carotid artery blood flow (ICA-BF) during simulated hypovolemia and noninvasive positive[…] [ncbi.nlm.nih.gov]

Dehydration

Abstract This hospital-record review describes the clinical profile of hypernatremic dehydration in neonates. 49 neonates (3.4% of the total admitted newborns) developed hypernatremic dehydration between January 2014 and August 2015. The major presenting complaints were fever (34.6%), poor feeding (42.8%), loose[…] [ncbi.nlm.nih.gov]

Cervical Spondylosis

Cervical Spondylosis is a condition in which abnormal deterioration of the cervical cartilages and vertebrae causes chronic neck pain. It is usually the result of prior a damage to the neck, including work or life-style activities, although its occurrence is affected by genetic factors because some families show[…] [symptoma.com]

Syringomyelia

Syringomyelia is a generic term referring to a disorder in which a cyst or cavity forms within the spinal cord. This cyst, called a syrinx, can expand and elongate over time, destroying the spinal cord. The damage may result in loss of feeling, paralysis, weakness, and stiffness in the back, shoulders, and extremities.[…] [en.wikipedia.org]

Hematomyelia

A 34-year-old woman with Factor XI deficiency presented with rapidly progressive quadriplegia following a 1-week prodrome of cervical pain.
