Podcast 581: Alcohol Complications

\Contributor: Don Stader, MD

Educational Pearls:

• Altered mental status/confusion are major symptoms associated with both alcohol use and withdrawal.
• Wernicke's encephalopathy is a triad of symptoms of confusion, internuclear ophthalmoplegia, and confabulation
• The treatment for Wernicke's is IV thiamine or vitamin B1
• Untreated Wernicke's leads to Korsakoff's syndrome where a prolonged thiamine deficiency leads to worsening brain function
• Subdural hematomas from torn bridging veins are common in alcoholics because of the combination of frequent falls and cerebral atrophy caused by alcohol.
• Alcohol is a major cause of heart failure and atrial fibrillation; "holiday heart" is a-fib induced by binge drinking where high levels of acetaldehyde from the metabolism of alcohol excite the heart.
• Frequent alcohol use is linked to esophageal cancer
• Alcoholic cirrhosis can lead to a multitude of complications including esophageal varices that can rupture often with fatal outcomes
• Aspiration pneumonia is more common in alcoholics because of a depressed gag reflex and alteration of oral flora
