32
What is addiction?
Persistent craving, loss of control over drug use, compulsive use, and a strong tendency to relapse after withdrawal
33
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

46
Management of hyperthyroidism

47
Side effects of PTU and methimazole
Low white blood cell count in less than 1% of patients. For this reason, it requires regular blood monitoring

How long does it take for PTU and methimazole to work?
Clinical improvement is seen after 1 month but it is 3 months before thyroid level decreases
49
What are some side effects of radioactive iodine?
Soreness of neck or brief worsening of symptoms. Patients with opthalmopathy may experience worsening of their symptoms. Eventually, many patients become hypothyorid and need to take thyroid replacement
50
How do you monitor a patient after she is given radioactive iodine?
Check TSH every 2-3 months until it has stabilized and every 6 mos or so after that
51
Treatment of hypothyroidism
Levothyroxine. Check TSH one month after starting. In primary hypothyoridism, check annually. In secondary hypothyroidism, must monitor more closely
52
Most common mechanism of injury of ankle sprain
plantarflexion and inversion ("down and in")
53
History of snap or tear
Diagnostically significant in a knee injury but not an ankle injury
54
The lateral stabilizing ligaments of the ankle
Are the most commonly injured in plantar flex and inversion injuries; These include the anterior talofib, posterior talofib, and the calcaneofibular ligament
55
Tests to assess the stability of the lateral stabilizing ligaments of the ankle
Anterior drawer test for anterior talofibular ligament; Inversion test for calcaneofibular ligament; Posterior talofibular ligament is rarely injured so there's no test for it
56
How do we assess for ankle sprain secondary to eversion and rotation (much less common MOI)
Cross-legged test detects high ankle tibiofibular syndesmotic sprain
57
Grading ankle sprains I, II, III
I is stretching or small tear (no bruising, no loss of stability); II is incomplete tear (brusing common, moderate functional impairment); III is complete tear and loss of integrity of the ligament (mechanical instability)
58
Peroneal tendon tear is usually secondary to what kind of injury? How does the pain present?
Usually inversion injury or repetitive trauma. Persistent pain posterior to the lateral malleolus
59
Talar dome fracture
Initial xrays may miss. Watch out for avascular necrosis
60
Tendonitis in the ankle
Usually involves posterior tibialis tendon. Swelling, warmth and stiffness are common
61
Subtalar injury
Dislocation invoves talocalcaneal and talonavicular joints
62
Tarsal tunnel syndrome
Entrapment of the tibial nerve. Pain, tingling, and burning sensation along the sole of the foot and/or the inside of the ankle
63
Syndesmatic injury
Positive ankle squeeze test. Involves interosseous membrane and anterior inferior tibiofibular ligament
64
Ottawa ankle rules
Sensitivity of 97 to 100%. Xrays of the ankle are needed if: there is pain in the malleolar zone and EITHER bony tenderness along the distal 6 cm of the posterior edge of the malleolus OR inability to bear weight both immediately and in the ED
65
Ottawa foot rules
Xrays are indicated if there is pain in the midfoot region and EITHER bony tenderness at the navicular base or base of the fifth metatarsal OR inability to bear weight both immediately and in the ED
66
