Case Study #1
A 48-year-old man is admitted to a hospital because of pneumonia. Two days after the hospitalization, the patient becomes agitated and restless with tachycardia and hypertension. On physical examination, the patient is noted to be alert, but anxious, tremulous, and disoriented to place and time. And these findings differ from those on examination at admission. His alcohol history is significant (eg, drinking 3 or more vodkas a day for years; most recent alcohol intake occurred 2 days before coming to the hospital), but no history of liver diseases or alcohol withdrawal is evident. His wife is at his bedside and validates his alcohol intake. Subsequent physical examinations reveal no specific changes from the admission assessment except disorientation and anxiety. His respiratory status appears stable, and repeated CXR does not show any progression compared with the admission assessment.
