A
Brain abscess
-do head CT
2
Q
Follicular Thyroid cancer Dx

- mets hematogenously
3
Q
Papillary thyroid carcinoma
A
- COMMONEST thyroid cancer
- look for Psammoma bodies,
- FNA shows large cells with ground glass cytoplasm, inclusion bodies in pale nuclei and central grooving. Encapsulated

9
Q
Lumbar spinal stenosis
A
- Presents as lower back pain and pain in legs/difficulty walking.
- Results from anything that narrows the spinal canal and compresses that nerve roots.

13

Myasthenia Gravis tx
-Step 1?
2?
Crisis?
A
1) Pyridostigmine for all
2) if sx continue then add glucocorticoids, azathioprine, mycophenolate mofetil, and cyclosporine

27
Langerhans cell histiocytosis
- in bone it presents as a lytic long bone lesion w/ pain and high calcium. Associated w/ pathologic fractures. Usually in children.

29
Staph pneumonia
OBVIOUSLY is from IV drug users!!
| -causes cavitary lesions
30
Pneumonia in a HIV pt

Intensive HTN control (NOT GLYCEMIC CONTROL!!)
38
Antibodies for resolved Hep B infection
| Antibodies for Hep B vaccination

- Dig will increase the ectopy of atria and ventricles. It also increases vagal tone and promotes AV block. This combo leads to...
- Atrial tachycardia w/ AV block.
45
Pt clearly had a stroke. What do you order next?
CT of the head WITHOUT contrast to rule out hemorrhage
46
What do you order to dx kidney stones?
US if it is an option.
