A

Both cause azotemia, hyperkalemia, and teratogenicity

Q

Patient presents with fever, hematuria, neuropathy, joint pain, and palpable purpura. What is a possible diagnosis?What labs should be ordered? What would be seen on angiography?

A

Polyarteritis nodosa

Labs:
CBC: increased WBC, decreased Hgb and Hct
ESR: increased
UA: proteinuria, hematuria
p-ANCA (perinuclear-AntiNeutrophil Cytoplasmic Antibodies): negative

Angiography:
Numerous aneurysms (beads on a string)
17
Q

Who typically gets polyarteritis nodosa? How is polyarteritis nodosa treated?

A

Young males

Corticosteroids or other immunosuppressant agents

18
Q

An old lady comes in with a new onset headache, temporal tenderness, and jaw pain. What should be checked on exam? What should be done?

A

This could be Temporal (Giant Cell) Arteritis…check her eyes

Give Prednisone first…then get a biopsy

19
Q

A youngish Asian woman (10-40yo) presents with malaise, vertigo, syncope, and fever. On exam she has decreased carotid and limb pulses. What is on the differential? What diagnostic tools can be used? How should it be treated?

A

Takayasu arteritis (inflammation of aorta and its branches)

Angiography, CT, or MRI can be used

Give corticosteroids or other immunosuppressants
Bypass grafting

20
Q

What is seen on biopsy with Takayasu arteritis?

A

plasma cells and lymphocytes in media and adventitia
Giant cells
Vascular fibrosis

21
Q

Patient presents with asthma-like symptoms, mononeuropathy (pain, numb, or weak), and has a rash. What should be considered? What labs should be drawn? How should it be treated?

A

Allergic granulomatosis with angiitis (Churg-Strauss syndrome)

Labs:
CBC: increased eosinophils
ESR: increased
p-ANCA: increased

Corticosteroids or immunosuppressants

22
Q

Patient comes in with abdominal pain and a papular rash on lower limbs. On history, find out had a URI not too long ago. What labs should be drawn? What should be watched for?

A

Check IgA…serum, purpura biopsy, renal biopsy

Spin down a urine to look for casts…IgA nephropathy

23
Q

Young patient comes in with fever, lymphadenopathy, conjunctival lesions, maculopapular rash, edema, and desquamation of hands/feet. What is the likely diagnosis? What should be monitored? What are treatment options?

A

Kawasaki disease

Get an echo (+/- dobutamine) or angiography for coronary vessel irregularities

Treat with aspirin or IV gamma globulin…often self-limited

24
Q

What are the possible complications to a large VSD that is not fixed?

A

Eisenmenger’s syndrome (not common in developed world)

Increased risk of endocarditis

25
Q

Patient had a known VSD, but nothing was done, and now presents cyanotic. What happened

A

Eisenmenger’s syndrome

L –> R shunt –> increased pulmonary pressure –> R –> L shunt –> cyanosis…irreversible

26
Q

What do patients with a known ASD need for surgeries/dental work?

A

Endocarditis prophylaxis (I’ll look this up…because I thought it was changed to just foreign valves)

27
Q

Would it be a good thing for an extreme-sports enthusiast to have an ASD?

A

No…more likely to desat at high altitudes and more likely to have decompression sickness during deep sea diving

28
Q

What are possible complications of an ASD?

A

Eisenmenger’s syndrome
RV dysfunction
Pulmonary HTN
Arrhythmias

29
Q

Who is most likely to have a PDA?

A

Premature girls

30
Q

How is PDA treated?

A

Indomethacin…decreases PGE2

31
Q

A newborn is found to have transposition of great arteries and has actually survived so far. What other vascular defect does this baby likely have? What else is probably going on with the kid?

A

PDA or VSD (allows mixing of venous and arterial blood)

Apert syndrome, cri-du-chat syndrome, trisomy 13, 18, or 21

32
Q

In utero, a baby was found to have TGA, what can be done after birth to prolong life?

A

Give PGE2…keep PDA open

Surgery

33
Q

What should be checked in a baby found to have Down Syndrome after birth? (I guess old mom didn’t want prenatal ultrasounds…otherwise this could have been seen earlier)

A

Endocardial cushion defects (20% tris-21 people)

34
Q

Who is most likely to have tetralogy of Fallot? What are the four parts?

A

Cri-du-chat, trisomies 13, 18, or 21

Pulmonary stenosis, VSD, overriding aorta, and RVH
