SG2 Flashcards
Abdominal aorta normal diameter
less than 2cm
Signs of Cushing’s syndrome that are not as obvious
Easy bruising, muscle weakness
Calculating basal metabolic rate
body weight in pounds times 10. multiply by 1.3 if sedentary, 1.7 heavy activity, 1.9 intense activity
Calculating LDL
LDL= total cholesterol- HDL- triglycerides/5
USPSTF lipid screening guidelines
All men over age 35, all women over age 45 and younger adults (20-35) with other CHD risk factors
Management of LDL dyslipidemia- what kind of diet is recommended?
saturated fat less than 7% of calories; less than 200 mg of cholesterol per day; increased soluble fiber (10-25 g/day) and plant sterols to enhance LDL lowering
Side effects of statins
Hepatic dysfunction. So check LFTs before initiating after 12 weeks of therapy, periodically, and with any dose adjustment. Another SE is myopathy
Other meds that treat LDL dyslipidemia besides statins
Bile acid sequestrants, nicotinic acid (niacin), fibric acid derivatives, ezetimibe
Bile acid sequestrants- what are the benefits and side effects
More modest effect on LDL and HDL; can cause increase in triglycerides, may cauase severe GI distress and constipation
Nicotinic acid (niacin)- how does it work to lower LDL and what are the side effects?
more modest effect on LDL; this is the most effective agent for HDL increasing; this can decrease triglycerides; the side effects include body flushing (which can be reduced by taking ASA before the niacin dose)
Fibric acid derivatives- what are they good for?
These are the first line agents for reducing triglcerides; they canse a modes effect on decreasing LDL; these can raise the HDL as well as a benefit
Ezetimibe- how does it work?
Inhibits the absorption of cholesterol at the intestinal brush border; it increases cholesterol clearance; however, it is unclear whether it decreases atherosclerosis or CHD
Monitoring lipids
Check lipids every 6 weeks after starting therapy and every 6-12 mos when patients is on a stable dose
When is medication for weight loss indicated?
When BMI is over 30 or over 27 with risk factors
What are some meds for weightloss?
Orlistat and prentermine
How does Orlistat work?
GI lipase inhibitor that decreases fat absorption. This is the only medication currently FDA approved for weight loss
How does prentermine work?
First of all, you should know it is indicated only for short term use. Next, the side effects are those of other stimulants, tachy, hypertension, tremor, insomnia
When is bariatric surgery indicated?
BMI over 40 or over 35 with comorbidities
How many migraine episodes are needed for diagnosis?
5 episodes are needed for migraine diagnosis
What is the character of a migraine headache?
unilateral pulsating
How long do migraines typically last?
4 to 72 hours
Are migraines aggravated by physical activity?
Yes. However, tension and cluster are not
How many episodes of a tension headache are required for diagnosis?
10 episodes are required for diagnosis
How do you describe the pain of a tension headache?
bilateral or occipital, with a pressing quality
Are tension headaches associated with phono and photophobia like migraines?
Yes, they are associated with photo and phonophobia like migraines
How long do tension headaches last?
30 mins to 7 days
Are tension headaches aggravated by physical activity?
No, only migraines are aggravated by physical activity
How many episodes of cluster headaches are requires to make the diagnosis?
5 episodes of cluster headaches are required to make the diagnosis
How long do cluster headaches last?
15 mins to 180 mins
Criteria for diagnosis of medication overuse headache
Over 15 headaches per month; regular overuse of an analgesic for over 3 mos; development or worsening of headache during medication overuse
Narcotic dependence
Causing clinically significant impairment manifested by at least three of the following: tolerance, withdrawal, increased doses, desire or inability to cut down, significant amount of time spent in search of the drug, interference with activities, continued use despite physical or pscyh problems due to the drug
What is addiction?
Persistent craving, loss of control over drug use, compulsive use, and a strong tendency to relapse after withdrawal
Guideline for imaging for headache
If patient has migraine with atypical headache patterns or focal neuro signs, patient is high risk for a significant abnormality; study results would alter management
Medications that might trigger headaches
progesterone (birth control or hormone replacement); tobacco; caffeine; alcohol; aspartame and phenylalanine (in diet colas)
Migraine-specific abortive meds
tryptans, ergot alkaloids
Contraindications to use of tryptans for migraine abortion
Use of ergotamine, use of MAOI, history of hemiplegia or basilar migraines, pregnancy, CVD or uncontrolled hypertenson, in combination with SSRIs may cause serotonin syndrome
Contraindications to the use of ergot amines for migraine abortive
Use with tryptans; heart disease or angina, hypertension, or peripheral artery disease, pregnancy, renal insuff, breast feeding
