begins with blackouts; alcohol is now required by person
phase 2: early alcoholic
person has lost control over alcohol use. physiological dependence is clearly evident
phase 3: Crucial
person is intoxicated more than they are sober
phase 4: chronic
peripheral nerve damage, pain, burning, tingling, prickly sensation of extremities
due to thiamine deficiency
-inadequate intake
-malabsorption
alcoholic peripheral neuropathy
sudden oset of muscle pain, swelling, and weakness, reddish tinge to urine, rapid rise in muscle enzymes (LDH, CPK, AST)
acute alcoholic myopathy
gradual muscle wasting and weakness of skeletal muscles
chronic alcoholic myopathy
Most serious form of thiamine deficiency
characterized by paralysis of ocular muscles, diplopia, ataxia, somnolence, and stupor
Wernicke’s encephalopathy
Syndrome of confusion, loss of recent memory, and confabulation in alcoholic pts
Korsakoff’s pyschosis
effect of alcohol on heart is an accumulation of lipids in myocardial cells, resulting in enlargement and weakened condition
Alcoholic cardiomyopathy
inflammation and pain in esophagus occurs bc of toxic effects on esophageal mucosa and also bc of frequent vomiting assoc with alcohol use
Esophagitis (esophageal varices)
inflammation of stomach lining characterized by epigastric distress, n/v, distension
gastritis
decreased exercise tolerance, tachycardia, dyspnea, edema, palpitations, nonproductive cough increased CPK, AST, ALT, LDH
Treatment is TOTAL ABSTINENCE from alcohol
alcoholic cardiomyopathy: looks like CHF or arrhythmia
usually occurs 1-2 days after binge of excessive consumption, constant, severe epigastric pain, n/v and abdominal distension
pancreatitis
leads to pancreatic insuffiency resulting in steatorrhea, malnutrition, wt loss, and DM
chronic pancreatitis
enlarged, tender liver, n/v, lethargy, anorexia, high WBC, fever, jaundice, ascites and weight loss
alcoholic hepatitis
widespread destruction of liver cells which are replaced by fibrous tissue; portal hypertension, ascites, esophageal varices, hepatic encephalopathy due to high ammonia levels
cirrhosis of liver
impaired mental fxn, apathy, euphoria/depression, sleep disturbances, increased confusion, coma or death possible
Tx: abstinence from alcohol, no protein, neomycin or lactulose
hepatic encephalopathy
Hematologic effects of alcohol
leukopenia and thrombocytopenia
abnormal facial features, small head size, shorter than ave weight, diff paying attention, poor memory, diff in school, learning diffs, speech and lang delays, poor reasoning skills, intellectual disability, sleep and sucking probs as baby, vision or hearing probs, heart, kidneys, and bone probs
FAS
BAC of 100-200mg/dL
intoxication occurs and withdrawal occurs within 4-12 hours of cessation or reduction of heavy use
barbs, non-barbs, anti anxiety agents, club drugs
sedative-hypnotic
primarily affect nervous tissue: depress activity of brain, nerves, muscles, and heart. reduce metabolism
mild sedation-death
sedative hypnotics: barbs, non barbs, antianxiety agents and club drugs
decreased dreaming while on drug but rebound insomnia and excessive dreams during withdrawal
sedative hypnotics: barbs, non barbs, antianxiety agents and club drugs
inhibits RAS for respiratory depression
sedative hypnotics: barbs, non barbs, antianxiety agents and club drugs
amphetamines, synthetic stimulants, non-amphetamine stimulants, cocaine, caffeine, nicotine
stimulants
high doses lead to hypotension (decreased CO, cerebral blood flow, and direct impairment of myocardial contractility)
sedative hypnotics: barbs, non barbs, antianxiety agents and club drugs
