Flashcards in AAFP Review Questions Deck (466)
Hallmark lab finding in polymyalgia rheumatics
Markedly elevated ESR
OCPs and cancer
Prevent ovarian cancer and may cause breast cancer
Combined OCP vs. progestin-only
Progestin only pills (a.k.a. “POPs” or “the mini pill”) are associated with more break-through bleeding and slightly higher failure rates than the combination pill that contains both estrogen and progesterone. Progestin only pills are more difficult to take, because they must be taken at the same time every day to maintain their efficacy. They are usually reserved for women who have a compelling reason avoid estrogen. Such patients might include women with migraine headaches, smokers over age 35, patients in the postpartum period, or women with clotting disease, cardiovascular disease, uncontrolled HTN, SLE, or hypertriglyceridemia
First step in evaluating short stature
-familial short stature
-constitutional delay of growth
Distinguish between familial short stature and constitutional delay of growth
Bone age (X-ray of hand and wrist)
-FSS: bone age matches chronological age
-CDG: bone age lags behind chronological age
(both have normal growth velocity)
Do we treat bacteruria of pregnancy?
YES (EVEN IF ASYMPTOMATIC), to prevent pyelonephritis
- Without treatment, as many as 30 to 40 percent of pregnant women with asymptomatic bacteriuria will develop a symptomatic urinary tract infection (UTI).
-We screen all pregnant women at least once for asymptomatic bacteriuria. Screening for asymptomatic bacteriuria is performed at 12 to 16 weeks gestation with a midstream urine for culture. The diagnosis is made by finding high-level bacterial growth (≥105 colony forming units [cfu]/mL or, for group B Streptococcus, ≥104 cfu/mL) on urine culture in the absence of symptoms consistent with UTI.
-Management of asymptomatic bacteriuria in pregnant women includes antibiotic therapy tailored to culture results, which reduces the risk of subsequent pyelonephritis and is associated with improved pregnancy outcomes. Potential options include beta-lactams, nitrofurantoin, and fosfomycin
Treatment of bacteruria in pregnancy
[common bugs: E. coli, Klebsiella, GBS]
cephalexin, amoxicillin, amoxicillin/clavulanate, nitrofurantoin, and sulfonamides (but NO sulfonamides in 1st trimester d/t causing hyperbilirubinemia of the newborn]
At least 5d
At least 4 of:
-desquamation (esp. of fingertips, palms, and soles)
-polymorphous, nonvesicular rash
-cervical lymphadenopathy (often unilateral)
-dry or fissured lips
-"strawberry tongue" [Ddx: scarlet fever or Kawasaki disease]
DO-NOT-MISS DIAGNOSIS d/t life-threatening coronary artery aneurysms
Patients need serial echos to monitor aneurysms.
Treatment of Kawasaki disease includes intravenous immunoglobulin (IVIg) and corticosteroids, as well as aspirin to prevent thrombosis
Treatment of Kawasaki disease
Patients need serial echos to monitor aneurysms.
Intravenous immunoglobulin (IVIg) and corticosteroids, as well as aspirin to prevent thrombosis
How to choose allopurinol vs. probenecid
24 hour urine collection for uric acid
<600 mg: underexcreter --> probenecid
>600 mg: overproducer --> allopurinol
Two most common nonpathological reasons for high alfa-fetoprotein
1. Multiple gestations
2. Inaccurate gestational date
Blood on dipstick but no RBCs
Myoglobinuria (myoglobin cross reacts w/ hemoglobin on dipstick)
Prevent myoglobin-induced ATN in rhabdomyolysis
>200 / >120 in the absence of symptoms
increased blood pressure with signs and symptoms of end-organ damage such as papilledema, stroke, hematuria, headache, altered mental status, acute coronary syndrome, etc.
Treatment of hypertensive emergency
Treatment of hypertensive urgency
Oral antihypertensives (e.g., labetalol)
How to begin a new-onset eneuresis workup
This single test will allow screening for urinary tract infection, a common cause of new-onset enuresis, as well as diabetic ketoacidosis, diabetes insipidus, and water intoxication. Imaging and referrals are reserved for patients with histories and physical exams that suggest a structural cause.
The patient (usually 6 mo - 36 mo) usually presents with a history of sudden onset severe, crampy abdominal pain that is accompanied by drawing the legs up toward the abdomen and inconsolable crying. These episodes usually last 20 minutes and pain-free periods can follow. Usually the episodes become more severe and spaced closer together over time. Non-bilious vomiting can become bilious as the obstruction worsens. “Currant jelly” stool is a common description of the blood and mucus mixed stool that can occur with intussusception. Palpation of a “sausage-shaped” mass is also classic, but is not always appreciated on physical exam. Ultrasound imaging is not mandatory for diagnosis, but if performed, it may reveal pathognomonic “bull’s eye” or “coiled spring” lesions. Prompt treatment is necessary to avoid irreversible intestinal ischemia or bowel perforation. Air contrast enema is diagnostic and therapeutic.
Congenital rubella findings
Deafness and cataracts as well as numerous purpuric skin lesions, (“blueberry muffin” baby).
Congenital rubella syndrome occurs when the mother contracts rubella early on in her pregnancy – the risk of congenital rubella syndrome is very low after 20 weeks. Since the MMR vaccine contains a live attenuated virus, there is at least a theoretical risk of causing congenital rubella syndrome, and for this reason the vaccine is avoided in pregnant women.
HIV patient w/ CD4 < 200 needs what?
TMP/SMX for prophylaxis of pneumocystis jirovecii pneumonia
HIV patient w/ CD4 < 100 needs what?
TMP/SMX for prophylaxis of toxoplasma gondii
HIV patient w/ CD4 < 50 needs what?
Azithromycin or clarithromycin for prophylaxis of MAC
What is a positive PPD in a high risk patient?
>5 mm induration
(HIV/AIDS, immunocompromised/suppressed, close TB contact)
What is a positive PPD in a moderate risk patient?
>10 mm induration
(homeless, comes from a country with high TB rates, or is an i.v. drug user)
What is a positive PPD in a low risk patient?
> 15 mm induration
(no major TB RFs)
Management of shoulder dystocia
1. Fundal pressure (sufficient in most cases)
2. Corkscrew maneuver: delivery of the posterior arm and shoulder, flexion of the maternal hips, and rotation of the infant
3. fracturing the fetal clavicles or maternal symphysi
(RFs for shoulder dystocia:
Fetal macrosomia, gestational diabetes, maternal obesity, postdate pregnancy, and prolonged second stage of labor)
Most common complication of shoulder dystocia
Damage to C5-C6 --> waiter's tip
Congenital syphilis findings
Rash involving palms and soles, blood-tinged purulent nasal discharge ("the snuffles"), lymphadenopathy, organomegaly
