The document describes a case of a 79-year-old female patient who fell down the stairs after suddenly losing consciousness. She has a history of diabetes and hypertension. Upon examination, her left radial pulse was weak and there was a 20 mmHg difference in blood pressure between the left and right arms, suggesting subclavian steal syndrome. Further tests such as CT angiography would be needed to confirm.

The patient is a 54-year-old man who presented with dizziness. Upon examination, he was found to have left beating nystagmus that changed to right beating nystagmus. While peripheral vestibular signs were initially observed, central vestibular signs emerged later. Based on the history and examination findings, the possibility of either peripheral vestibular neuritis or central stroke was considered. Three physical exam findings - direction-changing nystagmus, skew deviation, and head impulse test - can help distinguish between peripheral and central causes of acute vestibular syndrome with high sensitivity and specificity.
