Dizziness/vertigo are important public heath care issues especially in elderly patients. Isolated dizziness/vertigo without neurological deficits has seldom been considered a symptom/sign due to vascular origin. Recently, some studies have suggested that vascular origin should be considered in cases of positional vertigo and isolated vertigo or dizziness when the etiology remains unclear. In this study, we tried to delineate the correlation of dizziness/vertigo and risk factors of stroke. ⋯ After careful examination and approach, a vascular origin should be considered in dizzy patients of unknown etiology.

Review Case Reports
Subacute combined degeneration caused by nitrous oxide intoxication: case reports.
Case reports with a comprehensive review of the current literature concerning subacute combined degeneration induced by nitrous oxide inhalation. A differential diagnosis should be considered when young patients present with progressive myelopathy because that the misuse of nitrous oxide has potentially serious outcomes. ⋯ Iatrogenic usage of nitrous oxide apparently resulted in subacute combined degeneration in our three patients. Recently, nitrous oxide misuse has increased among young people. Subacute combined degeneration of the spinal cord should be considered as a possible outcome of such abuse.
