Case Answers:
Case answers will be presented after review of the HPI.
Answer 1
Include questions about alcohol consumption and other substance use when discussing
nutrition and the use of prescription or OTC medications.
You should also include the following:
Answer 2
12 ounces of beer = 4 ounces wine = 1.5 ounces 80 proof liquor (a shot) = 10 - 12
grams of ethanol. One can of beer is usually 12 ounces so his 16 beers/week works out to
160 - 192 grams of ethanol. Each gram of alcohol has approximately 7 kcals and on average,
ethanol accounts for about half an alcoholics caloric intake.
Answer 3
There is no "typical alcoholic personality." This questions is meant to
stimulate discussion of personal biases towards alcoholics. The "skid row bum"
stereotype is invalid, representing only about 5% of those with alcohol dependence. 50% of
male drinkers have temporary alcohol-induced problems, usually in the late-teen to
young-adult years; 10% of men and 5% of women develop pervasive and persistent
alcohol-related problem, also termed "alcoholism". Most have jobs and family
members who may be affected the alcoholism. In the medical setting, particularly the
inpatient ward, prevalence is even higher and may reach 20-30%.
Answer 4
This patient does not drink in moderation (>2 drinks/day max., inconsistent
limits, drinks alone, not heed warnings). He demonstrates risky use (driving while
intoxicated) and hazardous use (>4 drinks per occasion for men, and >14 drinks per
week on average). Harmful drinking is demonstrated by his DUI, effect on his interpersonal
relations with his girlfriend, missed days at work, and potential cause of his collar bone
fracture and ankle sprain. Alcohol dependence is demonstrated by his increased drinking
pattern suggestive of tolerance, and drinking for relief. If his morning
"illness" is thought to be secondary to mild alcohol withdrawal, this would
signify alcohol dependence.
Answer 5
DSM Criteria for alcohol dependence includes evidence of abuse (alcohol-related
life impairment interfering with functioning within the previous 12 months) and evidence
of a strong compulsion to use alcohol, accompanied by increased alcohol tolerance, or
physical signs of withdrawal when ethanol intake is abruptly reduced or ceases. Duration
criterion: some symptoms of the disturbance have persisted for at least 1 month, or have
occurred repeatedly over the previous 12 months. Dependence criteria require that three or
more of the following items be met:
Dependence and abuse are determined by functional impairment, NOT the absolute quantity of the substance used.
This patient has significant functional impairment, but additional questions to better characterize his morning illness (is it withdrawal?), his recent escalation of intake (is it due to tolerance?), etc. should be asked.
Answer 6
Answer 7
There is no test available to diagnose alcoholism. The ALT and AST have very low
sensitivity in diagnosing alcoholism. However, if the AST/ALT ratio is greater than 2, it
is likely that the patient has alcoholic liver disease. The GGT is a more sensitive marker
for alcoholic liver disease, although it is very nonspecific and may go up for other
reasons, such as phenytoin, phenobarbital, pregnancy, or other liver disease. The GGT
seems to go up after binge drinking and stay up for a couple of weeks. It may be useful as
laboratory confirmation of a clinical diagnosis. Some have estimated its sensitivity at
60% and its specificity at 80-90%. Bilirubin, alkaline phosphatase and LDH have less
importance in the diagnosis since they are insensitive and nonspecific. Normal LFTs
do not rule-out the diagnosis of alcoholism. BAL (blood alcohol level) is useful in the
acute intoxication setting, as in the ED and gives you some idea of tolerance - if the
serum level is high with little apparent impairment, it is suggestive of a high degree of
tolerance. The MCV is usually high but is non-specific and not diagnostic; the elevation
results from a direct toxic effect of EtOH on erythroblasts in the marrow.
Answer 8
This patient is in denial and demonstrates ambivalence about his problems.
Discussion should include the six components of a brief intervention:
This strategy mirrors the FRAMES program described in the OConnor article. Both have been shown to result in decreased alcohol intake.
